Polymeric Nanoparticles in Drug Delivery

Polymeric Nanoparticles in Drug Delivery Abstract TO DRUG TARGET For the past few decades, there has been a respectable exploration interest in the territory of drug conveyance utilizing particulate conveyance frameworks as transporters for little and huge particles. Particulate frameworks like nanoparticles have been utilized as a physical methodology to adjust and enhance the pharmacokinetic and pharmacodynamic properties of different sorts of drug particles. They have been utilized within vivo to secure the drug element in the systemic course, confine access of the medication to the picked destinations and to convey the drug at a regulated and managed rate to the site of activity. Different polymers have been utilized within the detailing of nanoparticles for drug conveyance exploration to expand helpful profit, while minimizing side impacts. Here, we survey different parts of nanoparticle plan, characterization, impact of their attributes and their requisitions in conveyance of medication atoms and restorative genes. Introduction for reflective statement The utilization of nanotechnology in medicine and all the more particularly drug conveyance is situated to spread quickly. At present numerous substances are under examination for drug conveyance and all the more particularly for growth help. Interestingly pharmaceutical sciences are utilizing nanoparticles to diminish lethality and symptoms of medications and up to as of late finished not understand that transport system themselves may force dangers to the patient. The sort of perils that are presented by utilizing nanoparticles for medication conveyance are past that postured by traditional dangers forced by chemicals in established conveyance frameworks. For nanoparticles the information on molecule danger as got in inward breath lethality demonstrates to the way industry standards to explore the potential perils of nanoparticles. The toxicology of particulate matter varies from toxicology of substances as the forming chemical(s) could conceivably be dissolvable in living lattices , therefore impacting incredibly the potential introduction of different inward organs. Then again, retained species might likewise impact the potential lethality of the breathed in particles. Discussion For nanoparticles the circumstances is distinctive as their size opens the potential for intersection the different living hindrances inside the constitution. From a positive perspective, particularly the possibility to cross the blood mind hindrance may open new routes for medication conveyance into the cerebrum. Whats more, the nanosize likewise takes into consideration access into the cell and different cell compartments including the core. An incalculable number of substances are at present under examination for the arrangement of nanoparticles for drug conveyance, fluctuating from organic substances like egg whites, gelatin and phospholipids for liposome’s, and moresubstances of a chemical nature like different polymers and strong metal holding nanoparticles. It is evident that the potential collaboration with tissues and cells, and the potential harmfulness, incredibly relies on upon the genuine arrangement of the nanoparticle definition. This paper gives a review on a p ortion of the as of now utilized frameworks for medication conveyance. In addition the potential useful utilize additionally consideration is attracted to the inquiries how we ought to continue with the security assessment of the nanoparticle plans for medication conveyance. For such testing the lessons gained from molecule lethality as connected in particle toxicology may be useful. In spite of the fact that for pharmaceutical utilize the current prerequisites appear to be satisfactory to identify a large portion of the antagonistic impacts of nanoparticle definitions, it cannot be normal that all parts of nanoparticle toxicology will be distinguished. Thus, likely extra more particular testing might be required. Later years have seen exceptional development of exploration and provisions in the territory of nanoscience and nanotechnology. There is expanding confidence that nanotechnology, as connected to drug, will acquire critical developments the determination and medicine of malady. Designed nanoparticles are a critical device to understand various these provisions. It must be distinguished that not all particles utilized for therapeutic purposes go along to the as of late proposed and now by and large acknowledged meaning of a size ≠¤100 nm.however, numerous tests must be overcome if the provision of nanotechnology is to understand the expected enhanced comprehension of the patho-physiological premise of illness, carry more refined analytic chances, and yield enhanced thereapies. Toxicological dangers of nanoparticles To utilize the potential of Nanotechnology within Nanomedicine, full consideration is required to security and toxicological issues. For pharmaceuticals particular medication conveyance details may be utilized to build the alleged helpful proportion or record being the edge between the measurement required for clinical viability and the dosage prompting side effects ( (lethality). Notwithstanding, additionally for these particular details a toxicological assessment is required. This is especially valid for the provisions of nanoparticles for drug conveyance. Medicinal necessity For medicinal purpose certain routine measures requirement to be performed which will hang on to various potential dangers. In any case, it might be expected that not all dangers are at this minute known for the utilization of nanoparticles. Advantages Nanoparticle-based drug conveyance frameworks have extensive potential for medication of tuberculosis (TB). The essential mechanical favorable circumstances of nanoparticles utilized as medication bearers are high stability, high transport limit, achievability of fuse of both hydrophilic and hydrophobic substances, and possibility of variable courses of organization, including oral provision and inhalation. Nanoparticles can likewise be intended to permit regulated (supported) drug discharge from the network. These properties of nanoparticles empower change of drug bioavailability and decrease of the dosing recurrence, and may resolve the issue of nonadherence to endorsed help, which is one of the significant deterrents in the control of TB scourges. The accompanying are around the essential innovative points of interest of nanoparticles as medication transporters: high security (i.e., long timeframe of realistic usability); high bearer limit (i.e., numerous pill particles could be c onsolidated in the molecule grid); attainability of fuse of both hydrophilic and hydrophobic substances; and practicality of variable courses of organization, including oral organization and inward breath. These bearers can likewise be intended to empower regulated (supported) pill discharge from the matrix.the conduct of polymeric nanoparticles in the gastrointestinal tract is affected by their bioadhesive properties; grip of nanoparticles to the mucosa upgrades the retention of the copartnered medication, hence expanding its bioavailability. Consequently, lectins have been indicated to enhance mucoadhesion of the pill because of the biorecognition of the lectin-united transporters by glycosylated structures in the intestine.their significant focal points, for example, change of medication bioavailability and lessening of the dosing recurrence, may make a sound support for better administration of the malady, making specifically watched medicine more pragmatic and moderate. An alte rnate significant focal point of the nanoparticles is the plausibility of the adaptable courses of pill organization, including oral and inward breath courses. Furthermore, high soundness of the nanoparticles proposes long time span of usability. It could be normal that future examination will focus on the improvement of the vectorized conveyance frameworks consolidating preferences of the colloidal bearers, for example, expansive payloads of a medication, with animated focusing to the spoiling destinations. Conclusion The achievement of this innovation will likely rely on upon toxicological issues connected with comprehension of the destiny of nanocarriers and their polymeric constituents in the physique, and end of the danger of the remaining natural solvents. In this admiration, the likelihood of utilizing pill bearers produced out of characteristic polymers (e.g., chitosan or alginate) speaks to a magnetic point of view. The utilization of Nanotechnology in solution and all the more particularly pill conveyance is situated to spread quickly. For a long time pharmaceutical sciences have been utilizing nanoparticles to lessen danger and symptoms of medications. Up to as of late it was not understood that these transporter frameworks themselves may force dangers to the patient. The sort of risks that are presented by utilizing nanoparticles for pill conveyance are past that postured by expected dangers forced by chemicals in conveyance networks. In any case, in this way, the experimental ideal mod el for the conceivable (unfavorable) reactivity of nanoparticles needs and we have small comprehension of the nuts and bolts of the cooperation of nanoparticles with living cells, organs and life forms. A theoretical comprehension of natural reactions to nanomaterials is required to create and apply sheltered nanomaterials in medication conveyance later on. Moreover a nearby coordinated effort between those working in pill conveyance and molecule toxicology is vital for the trade of ideas, strategies and skill to accelerate this issue.

Economic and Social Effects of Prohibition Essay examples -- history

Economic and Social Effects of Prohibition There are many ways in which prohibition of alcohol consumption in the United States of America, damaged the very economic and social aspects of American culture, that it was designed to heal. â€Å"Prohibition did not achieve its goals. Instead, it added to the problems it was intended to solve.† On 16th January 1920, one of the most common personal habits and customs of American society came to a halt. The eighteenth amendment was implemented, making all importing, exporting, transporting, selling and manufacturing of intoxicating liquors absolutely prohibited. This law was created in the hope of achieving the reduction of alcohol consumption, which in turn would reduce: crime, poverty, death rates, and improve both the economy, and the quality of life for all Americans. These goals were far from achieved. The prohibition amendment of the 1920's was ineffective because it was unenforceable. Instead, it caused various social problems such as: the explosive growth of organized crime, increased liquor consumption, massive murder rates and corruption among city officials. Prohibition also hurt the economy because the government wasn’t collecting taxes on the mu lti-billion dollar a year industry. One of the main reasons that prohibition failed, was because it was difficult to control the mass flow of illegal liquor from various countries, mainly Canada. â€Å"Bootleggers smuggled liquor from oversees and Canada, stole it from government warehouses, and produced their own.† The newly established Federal Prohibition Bureau had only 1,550 agents, and â€Å"with 18,700 miles of vast and virtually unpoliceable coastline, it was clearly impossible to prevent immense quantities of liquor from entering the country.† Not even 5% of smuggled liquor was ever actually captured and seized from the hands of the bootleggers. Bootlegging had become a very competitive and lucrative market with the adaptation of prohibition. This illegal underground economy fell into the hands of organized gangs who over powered most of the authorities. Most of these gangsters, secured their businesses by bribing an immense number of city officials. Mainly government agents and people with high political status such as: Mayors, Judges, Police Chiefs, Senators and Governors, found the ir names on gangsters payroll. To some surprise, the consumption ... ...ederal officers to enforce the prohibition law. Many of those officers found themselves in the midst of the exchange of dirty money between the bootleggers and themselves. Tax dollars were also spent on prosecuting bootleggers who got captured. Millions of dollars annually were spent convicting and keeping the prisoners in jails. Other economic problems were that citizens found themselves â€Å"drinking away† their pay cheques. These economic problems resulted in the government not taking in as much money as they could have, and spending money in areas that could have been avoided, if prohibition hadn’t existed in the first place. It was apparent that Prohibition didn’t achieve its goals, instead, it added to the existing economic and social problems, as well as creating new problems that would be prominent in today’s society. Organized crime grew into an empire, disrespect for the law grew, the per capita consumption of alcohol increased dramatically, city officials fell to gangsters, and the government lost money. It is obvious that prohibition was a miserable failure from all points of view. Reasonable measures were not taken to enforce the laws, so they were practically ignored.

Canvas Art Essay

The subjectivity of perception makes art what it is. Art is all about perception and individuality, since everyone has a different background, experience, taste, and opinion about any artwork. To determine the extent to which perception plays a role in the development, and the existence, of the arts, it is essential to identify the knowledge issues of perception in regards to the area of knowledge. First, is perception consistent and definite? Does previous knowledge (prejudice) influence how one perceives an artwork? Is perception subjective? These questions will be explored using one all-purpose example in the arts: El Greco’s dramatic and expressionistic artworks. Firstly, perception is not universal in terms of time, as very evident with El Greco’s works. Virtually all of El Greco’s paintings were disdained by his contemporary painters and the public during his lifetime, 1541-1614. His works opposed too many aspects of Baroque style, which was popular in the 17th century. El Greco, therefore, had no followers and no audience at that time; his works were considered to be unnatural and overly-complex. However, in the 20th century, his works greatly influenced painters, leading to the birth of expressionism and cubism. For example, Pablo Picasso and Paul Cezanne studied El Greco’s structural compositions, his ability to interweave space and form, and the special effects of highlights, which were all disregarded in the 17th century. Also, Jackson Pollock, an expressionist, also followed El Greco’s expressionistic composition. Therefore, the â€Å"unnatural† and â€Å"overly-complex† features in the 17th century became the dominant characteristics of the new form of Expressionism. In general, perception is indefinite, with the ability to change over time: the time that a piece of art is created and perceived influences the way it is perceived. Also, previous knowledge and experience significantly influences perception. For instance, The Burial of the Count of Orgaz, El Greco’s most famous work today was presented at the Louvre in 1838. At that time, the audience knew, ahead of time, of El Greco’s life, career, and works; therefore, there was much enthusiasm and attraction to the painting. Meanwhile, The Burial of the Count of Orgaz was also studied in art schools in the 19th century where students analyzed its composition and form. However, before the students knew the title of the artwork and its artist, they had little interest and fondness for the work. Therefore, this reveals how previous knowledge (in this case, of El Greco’s life, artistic talent and fame) affects how it is perceived. Without that knowledge, The Burial of the Count of Orgaz could have simply been an amateur’s painting. This brings up the same issue once again. Knowing that the artwork is by El Greco, one may have a positive bias to the work, hence perceiving the painting to be better than it actually is. Lastly, perception is very limited in that it is very subjective. For example, we are selective in what we perceive, ignoring certain aspects while emphasizing others. For instance, in El Greco’s El Espolio, or The Disrobing of Christ, the oppression of Christ by his cruel tormentors is believed to be artist’s intensions; such studies emphasize El Greco use of vertical and lateral space of the canvas to present this idea. However, some critics say that the subject, rather, is to satirize the situation, since Christ is looking up to Heaven while his figure is segregated from the other people and the violence. Also, there is a figure in the painting’s background that is pointing at Christ accusingly. Therefore, it is evident that in these various analyses, different aspects of the painting are emphasized. The real meaning of any artwork is, consequently, not known and cannot be proven in any way. No one sees all the details that another sees in an artwork, hence making it very subjective. This knowledge issue links with the question that cultural background influences the subjectivity and limitations of perception. My prior experience may cause myself to view an artwork in a certain way, and not another. For instance, since I am religious, I regard El Greco’s El Espolio to be a genuine presentation of the oppression of Christ by his tormentors; I do not perceive it to be a satire of his death.

Benefits of Video Games Essay

In today’s frantic and stressful society, a desire to escape sometimes is imminent. There are piles of work to do, constant headaches, and relationship tensions are rising. In this current condition one may be aware that it will be impossible to get anything accomplished. What one really needs is a chance to get away from it all, to replenish the mind and release all of their apprehension. A relaxing vacation to a secluded private island would do the trick, but of course this is impractical. Instead, at no cost one can fully immerse into a lush, stunning virtual paradise oozing with beauty and serenity. This is the magnificence of the modern video game world; it lets a person be somebody they could only dream of, construct amazing structures and inventions, or can even provide relief and fulfillment. However, stress relief and personal enjoyment are not the sole advantages. Video games should be more widely accepted and integrated into the daily and professional lives of individuals because of the many positive effects they create, which include: self satisfaction, educational and economic opportunities, advances in technology and science, and the spawning of creativity and ingenuity. One of the age old attacks against video games is the statement that they contain an addictive allure that grabs hold of students and chokes the academic life out of them; well, according to recent studies, quite the opposite may be observed. In a study of young children age four and five, conducted by the Ready to Learn Initiative, it was found that through the addition of digital devices and video games into a school curriculum, it was possible to greatly increase letter recognition and early literacy skills. A further study by the Education Department Center found that kindergarteners with poor home conditions, who had experienced a video game based curriculum in preschool, were more adapted and successful (â€Å"The Benefits†). This prevents students from falling behind and creates interest in school. Although it is true that a handful of games possess no real advantages and are a distraction from work, the sheer number of games designed as educational tools or as brain-teasers clearly outweigh that fraction. In fact, nearly sixty percent of all video games are categorized as E for veryone, which primarily consists of healthy brain-growing challenges and activities. Large video game companies such as Big Fish, Broderbund, and Educational Insights are devoted to developing products that will wrack a player’s brain. Collectively, they provide exciting puzzles, history and science education in an interesting way, and dynamic math-oriented games (Gibson). The majority of players are hard at work improving their skills and cognitive abilities, while a few negative cases of video game players get all of the publicity. The benefits of games do not end there, however. (â€Å"The Benefits†) Many online video games provide valuable economic lessons and other important skills required in jobs and professional life. For instance, Second Life, a colossal in the MMORPG (Massive Multiplayer Online Role-Playing Games) industry, contains thousands of college students working for credit in their classes and career-related experience. Business students can take advantage of the game currency called Linden dollars, which can be exchanged for real money; they do this by selling in-game real estate and running retail businesses while learning about marketing, budgeting, and management. Fashion design and 3D-modeling students can collaborate to create articles of clothing and wardrobes. Even architectural students are taking advantage of the opportunities that Second Life provides by designing virtual buildings and structures (Driscoll). This video game opens up a world for these students to directly apply the information they are learning in class in a hands-on and logistically sound way. It also provides them with a source of income that supports and encourages their efforts. Other games and simulations are even used to ethically train medical students and to ready military recruits for the harsh reality of war. As a result of sophisticated games such as these, the pupils make less mistakes and are more prepared when they begin their high-risk careers. Aside from these rigid settings, other casual games are developing the skills of teenagers and adults in a more subtle way. Cooperative games such as World of Warcraft require teams of players to work together to reach a common goal. Each individual is given responsibilities and specific roles, and a few people are even selected to lead the group and provide direction and structure. Hundreds of similar games also teach the same teamwork, leadership, and responsibility to their players, which are all vital qualities to have in order to be successful in society. Not only can video games polish an individuals abilities, but they have the potential to facilitate advancements in the fields of technology and science as well. For example, the highly commended game, Foldit, requires the players to fold real proteins in the most efficient way as possible while competing against others online. Computer software alone is not very successful at predicting the future shapes of irregular objects, and so with the presence of the human minds puzzle-solving skills scientists have been able to create breakthroughs through utilizing this game (Toppo). For example, a sample of a monkey HIV protein which had mystified scientists for over fifteen years was recently introduced to the players for analyzing, who were then able to solve it in a mere ten days. The most proliferate solutions may even help scientists develop cures for many medical conditions such as AIDs, cancer, and Alzheimer’s disease (Toppo). However, playing video games such as these isn’t the only way advancements have been produced. According to Rick Nauert, PhD, the hardware used in gaming consoles, particularly the graphics cards, have been implemented into medical and research equipment in order to enhance the quality of MRI images and the maps produced by seismic waves. These improvements allow scientists to diagnose medical issues more readily, and helps geologists find new clues to the Earth’s history. In addition, as a result of the competition between elite video game companies such as Microsoft and its adversary Sony, this hardware is advancing so quickly that improvements are constantly available and becoming much more affordable. Smaller laboratories are now able to get their hands on this technology rather than being limited by their budgets. Video game antagonists will argue that gaming chains individuals to their televisions and leads to unhealthy and sedentary activity. Although this can be true in some cases, it is at least a lot more beneficial than passively watching a television program, which would most likely be the obvious second choice for activity. While immersing oneself into a video game, it is required to use critical thinking, imagination, and creativity. If one is about to tackle a ferocious monster, it is imperative that all available information is processed quickly and logically so as to avoid death. The same thing is true if one is navigating through a dangerous obstacle course, or solving a difficult puzzle. Games such as The Sims series allow players to harness their inner creativity to design their own houses, develop their families, and to interact in a simulation of real life. The Tycoon series includes several games such as Rollercoaster Tycoon, Zoo Tycoon, and Hospital Tycoon. In these games individuals act as the boss and coordinator of everything. One is required to build structures and fences, determine admission and event prices, and manage policies as well as staff. As long as one can think of an idea, it can be built and they can watch their ideas come to life. Another fascinating and interactive game is titled Spore. The goal of this game is to guide a group of organisms in the player’s control through the evolutionary stages of life. The individual starts in the cell level and directs their units to find food and reproduce. After undergoing several mitoses, they proceed to the creature stage where it is possible to design the organisms physical characteristics and mechanical features. How well the creature is created determines how adept its survivability and competitiveness is in the upcoming tribal, civilization, and space stages (â€Å"Spore†). Games such as these require a high level of entrepreneurship and originality in order to succeed and crowd out all of the competition. They develop the imagination and promote higher order thinking skills which are invaluable in our demanding society. Finally, the reason that hits home for the majority of video game users is its effectiveness as a stress reliever and object of entertainment. It can be safely assumed that on several occasions individuals have been locked up in their house on a rainy day with nothing to do. In this situation, it is too sloppy outside to do anything and everyone may be plagued with a sedentary attitude. This is a perfect time for them to pick up a controller to keep their brains functioning and themselves amused. Working towards a goal, trying to solve a challenging puzzle, or even just letting loose and dancing to music is a great way to keep oneself stimulated and content. Games allow players to work at their own pace and to make their own choices. This provides them with a healthy outlet to rid the mind of stress. The core of every game is its goal and reward system. There almost always is a goal, and there are always rewards for doing objectives correctly and improving upon past trials. These rewards supply individuals with gratification and a sense of accomplishment. Also, since there is such a wide variety in the genre of video games, everyone can find something that interests them. In short, games are fun; there are games designed to cater to everyone’s interests which can provide a few moments of carefree enjoyment. This reason alone is a good enough rationale to participate in the exciting world of video games. In conclusion, video games are the source of many positive effects. They have been proven to aid struggling students in their academic life, to increase cognitive abilities, and advance the fields of technology and science. They even spark the imagination of individuals and sharpen their ability to be creative. Many professions have already started to utilize the amazing potential that games hold, and the focus of video game companies has started to shift towards education and helpful mediums rather than pure entertainment and mindless violence. Although some may contain addictive qualities and promote physical inactiveness, they are a lot healthier choice than most forms of media and entertainment available today. Video games could very well be the future of education and productivity; outdated curriculum and textbooks could be replaced by them, and they should therefore be embraced and celebrated rather than shunned and ignored by some adults and children alike.

Free Your Inner Thinker Essays - Truth, Atheism, Agnosticism

Free Your Inner Thinker Essays - Truth, Atheism, Agnosticism Free Your Inner Thinker Free Your Inner Thinker Organized religions are laden with the debris of archaic, superstitious images. Everywhere people go they are submerged in biblical ignorance, religious illiteracy and historical stupidity (Edelen, The 10 Commandments). People are surrounded by cultic codes and images at every turn. This must stop! One organization that is taking a stand is called The Freedom From Religion Foundation. It is most commonly referred to as free thought. A freethinker is a person who forms opinions and beliefs on the basis of reason, independent of tradition, authority, or established belief (Barker). Freethinkers love to learn new ideas and are not satisfied with what is already known. Thus, all members must be free from the conformity of a bible, creed, or messiah. They must be allowed to think for themselves, rather than blindly follow tradition or cosmic absolutes. Freethinkers believe the truth and choose not to follow the lies and superstitions that are, inevitably, part of religion. Common mythological themes are saturated through out the bible, from the creation and flood myth to virgin birth and hero resurrection (Edelen, The Sin). Unlike conventional religions, Freethinkers beliefs are based on reality and reason. As defined in Nontract #11, What is a Freethinker, Reality is limited to that which is directly perceivable though our natural senses or indirectly ascertained through the proper use of reason (Barker). For an idea or belief to be considered true it must be testable, falsifiable, parsimonious, and logical. Every belief a freethinker has must have evidence or experiments to confirm it; all attempts to disprove it must repeatedly fail, require little to no assumptions, and be free from contradictions and character attacks (Barker). Freethinkers use the thinking part of there brain to understand the universe. Many people who dont understand free thought think that freethinkers lack morals. The morality of a freethinker can be summed up in one word, kindness. Morality is not a bunch of dos and donts but, instead, is based on human needs (Barker). Freethinkers try to be good and fair to everyone. They believe that all human beings should live in peace no matter what their race, sex, religion, what they think, who they love, or where they come from. They do their best to protect the earth and all its creatures. Religion promotes dangerous and inadequate morality based on blind obedience, rather than a careful use of reason to weigh the possible outcomes when faced with a moral dilemma (Barker). The most common philoshical question pondered is whether there is a meaning of life. Freethinkers know that the meaning of life must originate in the mind. Since the universe is mindless and the cosmos do not care, if you wish to have a purpose, YOU must care (Barker). Not all freethinkers believe in a meaning of life, as with all beliefs, individuals are free to accept or discard it. Where as many freethinker choose to believe there is no divine plan, most freethinkers find meaning in life. They find meaning in human compassion, social progress, the beauty of humanity, personal happiness, pleasure, joy, love, and the advancement of knowledge (Barker). Unlike convention religions, free thought requires an explanation rather than a designer to explain the complexity of life. One such explanation is Darwins theory of evolution along with natural selection. Freethinkers do not believe in a divine designer because the complexity of such a creature would be subject to the same scrutiny itself (Barker). Freethinkers also believe that religion is not only useless but also harmful. Historically, religion has always produced violence (Edelen Religion). From Moses to the Crusades, Henry VIII, Salem, Hitler, Kosovo. Edelen writes, it is the countries with out religion that are the least violent (Religion). He also stated in the same article that, America is the most religious of all industrialized nations, and yet is the most violent nation in the world. Many of the worlds most gruesome leaders believed they were performing gods work. Hitler himself wrote, I am completely convinced that I am acting as the agent of god. I am now a Catholic and will always remain so, in Mein Kampf (qtd in Edelen, Religion). Freethinkers do not believe that all religious people are

When the status quo will amend Essay Example | Topics and Well Written Essays - 250 words

When the status quo will amend - Essay Example This research will begin with the statement that the article of Cox and McCubbins develops an interest group model in which the lawmaker delegates his voting decision of his party leader. By that, the party leader has a plan for setting power. The model has six assumptions: members of assembly seek reelection to the House, the status of a member’s party affects his chance of reelection, a party’s standing depends on its lawmaking achievement, team engagement between legislators overcomes harmonization troubles, lawmaking members delegate to the central power and that the major explanation they do that is to delegate to his agenda acquiring power. The party’s head is the one who brings the agenda acquiring power. Therefore, in that respect is a bias to the majority party. The readings from the book Pivotal Politics attempt to understand in what cases gridlock happens. Gridlocks are when there will be no policy alteration from the status quo. The script sets off by explaining a few dissimilar hypotheses. It explains that gridlock is can be narrowed down if the majority party discusses bills with the minority party and it is even more uncommon if both the legislative and majority party are from the same party. Keith Krehbiel comes up with one directed model which depicts the ideology of the members of the house of Congress. It includes the median voter, the filibuster threshold, the president’s ideology and the veto threshold to override the president.

Charles Darwin Essay Example | Topics and Well Written Essays - 1000 words

Charles Darwin - Essay Example The life of Charles Darwin was as eventful as his works. He had keen interest in natural history from his boyhood days. Even though his mother died when he was just a little boy, he had a proper and cultivated upbringing courtesy to the care of his older brother Erasmus who looked after the schooling of Darwin. He picked up things that interested him quickly and paid attention to medical studies in the initial phase of his university life. Later on he learned taxidermy from John Edmonstone, a black slave born in Demarara in the continent of South America. The 'Journey of the Beagle' was the most important voyage that Darwin embarked on to explore the evolution of life on earth. His main objectives during this journey were to collect specimens of natural history and to investigate geology. Theoretical speculations were made along with acute observations on marine invertebrates. Darwin's stature as a scientist rose to dizzying heights by the time the Beagle returned in 1836. He settled in Cambridge to work on the publication of papers on evolution of species. Darwin's experimental observations on the Galapagos birds were among the primary topics of his theory, which were to be reassessed by our team of Darwin scholars. To proceed furthermore with the discussion in hand, let us look at the team that has made a reliving quest in the Galapagos to remind us of the pros and cons of natural imbalance. Our team consists of: 1) Frank J. Sulloway - Darwin scholar 2) William H. Durham - Evolutionary Biologist 3) Mark W. Moffett - Entomologist 4) Greg de Nevers - Botanist 5) Roger A. Lang, Jr. - Conservationist 6) Lance Milbrand - Cameraman 7) Kathy Turco - Sound Recordist 8) Patrick Gambuti, Jr. - Editor 9) Michael Whalen - Composer 10) Bruce Weiss - Producer/Director Frank J. Sulloway is one of the most famous Darwin scholars to have been inspired by the dedication and vision of Charles Darwin himself. Sulloways's life and philosophies have been shaped to a great extent by the adventurous spirit of Darwin. The sphere of his personal works is based on the evolutionary theory. Dr. Sulloway has used the basics of this theory to investigate into the relation between family dynamics and personality development. He has shown through research and supporting evidences that birth order has an impact on personality and behavior. His famous book Born to Rebel: Birth Order, Family Dynamics, and Creative Lives captures the spirit of scientific reasoning along with the indomitable thirst to explore the unknown, much in sync with the mind of his mentor Charles Darwin. (Sulloway.org, 2009) In the context, one might quote the words of Professor John Stevens Henslow at Cambridge University. He viewed Darwin as "the best qualified person I know who is likely to und ertake such a situation." (Sulloway, p. 121) The team collectively put a great deal of effort on its own to recreate the past exploration in the Galapagos Island in 2002. If we trace the similarities between what it was like 160 years ago when a young Charles Darwin made his visit to the island and how it was in 2002, we will first of all observe the physical as well as mental condition of the explorers. Each member of our chosen team of naturalists was at their fittest best when

Memorandum Essay Example | Topics and Well Written Essays - 750 words

Memorandum - Essay Example There are three candidates waiting for the heart transplant. The first candidate is Jerry, who has 3 teenage daughters studying and an unemployed wife. He is the bread winner in the family and is 5 years short of his retirement eligibility. His chances of living after a heart surgery will be 10-15 years. The second candidate is a 12 year old girl named Lisa. Her father works in the same hospital and offered to donate or give $2 Million dollars if the heart will be transplanted to Lisa. Lisa suffered 12 years of lifelong health issues and her chances of living after the surgery are not good. The hospital needed money to finish the construction of the specialized facilities that could help a lot of patients. The third candidate is Ozzie who happens to be a 38 years old homeless drug abuser. He is single and his heart condition is due to excessive intake of cocaine. He is also a volunteer in a certain charity and is teaching and helping troubled teens and giving them insights and wisdom against drug abuse and other issues. He signed a contract in the same charity and will continue working as a counsellor-mentor if he will get the transplant. Ethics is defined as the study of right or wrong conduct which focuses on moral situation (Ruggiero, 2008). In the situation above we can definitely say that making the decision on granting the heart transplant to only one of the three candidates is very difficult. There are a lot of things to consider. At first, when evaluating the three candidates, my feelings deeply sympathize for Jerry. Jerry is the most suitable candidate to get the transplant because he is the one which has the highest chances of living years and he has 4 family members who will be benefited. His 3 children need his support for their education and his wife is unemployed. But in making an ethical decision, feelings such as sympathy are not reliable for analysing moral issues (Ruggiero, 2008). When deciding by feelings, it is completely ignoring other people’s feelings (Ruggiero, 2008). According to J.S. Mill and Jeremy Bentham who are the most famous teleological ethicists, the most ethical action is the one based on utility or consequence and is the one which gives the most benefits and least harm. When making a decision on principles of utilitarianism, we should consider everyone affected by the decision. In this situation, Jerry will directly benefit 4 persons, Ozzie will benefit the troubled children and Lisa will help the hospital finish the specialized facilities and will help a lot of patients. Lisa’s condition may not be good after the heart transplant, but her father, an oncologist in the same hospital, will donate a big amount of $2 Million that wil l greatly help improve the hospital and will therefore serve and help more patients in the future. The benefit that Lisa can give is a long-term benefit to a number of patients. Granting the transplant to Lisa will definitely boost Dr. Doe’s loyalty to the hospital and his loyalty to the patients. Although Ozzie can help a lot of troubled children serving as a counsellor-mentor, his chances of recidivism to drug addiction is high. And if he

Relationship existing between nursing homes and leadership styles of nursing directors has a significant influence on the care quality. Nursing directors cooperate with administrators in establishing a long-term relationship with residents of nursing homes in order to foster a culture that can support development of the team. However, there are limited building preparations for the leaders of nursing homes, which cause limits on the leadership. On the other hand, administrators are focusing on adopting various initiatives that facilitate collaboration with nursing directors and social service directors to establish effective delivery teams. There are changes occurring in management of the old leadership in relations to personal behaviors and adaptation of new ones (Dixon, 2006). In this case, this paper will focus on the current study that results to offering relevant information concerning leadership in nursing homes and the roles of the individual teams that has resulted to impact on the psychosocial well-being of nursing home residents. According to Allen (2008), data obtained from the government indicates that control of the administrative leader on the care quality and services has a significant psychosocial well-being of nursing home residents. This has been attributed to recommendations by the regulators to foster changes that facilitate a culture embracing residents of nursing homes. Furthermore, embracing the residents of nursing homes focuses on their humanistic values and care that is personalized home like settings (Weiner & Ronch, 2006).

Accounting issues and analysis - Research Paper Example Section 14 indicates that during transition, an entity should disclose the immediate status in financial reporting in accordance with estimates made in accordance with the previous standard (national standard). R&D costs for prior years should thus be recognized under the US GAAP, and clearly indicated that they are reported under US GAAP in the first IFRS opening balances (IFRS 1, P28). Prior R&D costs should thus be expensed in accordance with SFAS 2, which limits capitalization of R&D costs. In regard to tracking future R&D costs, there is need for our entity to adopt IFRS. Just like in US GAAP, IFRS expenses all costs incurred in the research phase of a project. Nevertheless, it will be good for our entity to clearly separate research phase costs and development phase costs. In cases where a distinction does not exist, IFRS requires expensing of such costs, eroding the entity’s R&D assets. Tracking R&D costs under IFRS ensures that cost of materials incurred in development, employee costs during development, fees and patent amortizations are recognized as an asset, enhancing the balance sheet worth of the entity. This is outlined in section (IAS 38, p66). To account for the current project’s research and development costs, all development costs are capitalized and recognized as an asset in the balance sheet as per IAS 38R.57. On the other hand, all research phase costs are expensed. For the development costs to be capitalized there must be proof that there is intention to complete such products and sell or use them and the entity has the right and ability to use or sell such products. These costs should equally be in a position to generate future economic benefits to the organization. The entity should equally be in a position to measure costs incurred in development in a reliable manner.

Should Schools Have Uniforms Essay Example for Free

Should Schools Have Uniforms Essay Most high school students are teenagers. They are no longer children, but they still are not adults. Thus, they often want to wear latest fad clothes when they go to schools. However, I prefer the idea that they should be required to wear uniforms. First of all, uniform is one of the best features of each high school. Every country has its own national flag. Every football team has its own club emblem. Similarly, every high school has its own uniform. Uniform helps us to distinguish among schools. When we see a student at the street or on the media, we can tell where he is studying by the uniform that he is wearing. Moreover, each high school has a particular tradition. School uniforms can instill a feeling of school spirit. Wearing them can make students proud of their schools quintessence. Furthermore, wearing uniforms makes the classes more formal and more beautiful. If students have the right to decide what to wear to school, the classes appear to be in disorder. Hence, wearing the same clothes helps in creating a tidy learning environment. The teachers are interesting in imparting the knowledge to students, and the students are enthusiastic about studying more. It not only makes the teachers to feel comfortable in teaching, but it also helps the students to acquire better scholastic achievements. Finally, requiring all students to wear uniforms keeps high schools having high standards of discipline. To evaluate the quality of a school, besides providing superior learning programs, having a lot of books in libraries, building good buildings, the way its students obeying the schools rules is also one important factor. If the students attend classes regularly with uniforms, the school will have a good reputation. Many teenagers, as well as their parents, want them to be able to enter these schools. It ensures that the juveniles not only have better education, but they also are trained to become virtuous people. In conclusion, for the reasons above, I strongly agree that all high school students should wear uniforms at school. It makes the schools to be more beautiful, and helps the teachers and students in teaching and learning effectively.

Features of Perfect Competition

Features of Perfect Competition Contrast the features of perfect competition with those of oligopoly. (10) The comparison between perfect competition and oligopoly will be based on the following: number of buyers and sellers, nature of product, and barriers to entry of firms. Number of buyers and sellers Perfect competition is a market structure that is characterised by many buyers and sellers with each firms output representing an insignificant proportion of the total output. Hence, sellers cannot influence prices by changing its level of output. Thus, they accept the market price as given i.e they are price takers. Each firm then faces a perfectly elastic demand curve as shown in fig 1a. An example of a market that comes close to the perfectly competitive model is that of agricultural farming. How much the farmer sells his wheat for will depend on the prevailing price of wheat in the market. On the other hand, an oligopolistic firm produces a significant amount of the total market output. The seller can either influence the price or output. It can sell more by lowering price or increase price but sell less. This indicates that the firms demand curve is downward sloping. In addition, due to the small number of firms prevalent in the market, each firm now makes its decisions based on the reaction of other firms in the same industry. No firm can afford to ignore the actions and reactions of other firms in the industry. For example, there are only a few car manufacturers in the US such as Chrysler, GM and Ford Motors. If Ford Motors wants to increase sales, it can lower the price of its cars so that some buyers will switch from either Chrysler or General Motors but the increase in quantity demanded will be insignificant given that Chrysler and General Motors will follow the cut in price. This behaviour can be summarized by the kinked demand curve. Nature of product In perfect competition, each seller produces an identical product, thus they are perfect substitutes for each other. Since consumers think that the products are the same, they will not show any preference towards the goods of one firm over another. This means that sellers are not able to arbitrarily raise their prices for fear that consumers switch to other firms. Firms in perfect competition are price takers, and the demand for their goods are perfectly price elastic, hence the horizontal demand curve. In oligopoly, firms may either be producing a homogenous product or a differentiated product. When the product is differentiated, the oligopolist can increase the price and the output would not fall significantly. This implies substantial market power for the firms in an oligopoly. Even when the good is homogenous like steel or aluminium, the firm is likely to differentiate in terms of the services and terms of conditions, hence the downward sloping demand curve. Barriers to entry There are no barriers to entry or exit in a PC industry so the markets will consist of a large number of small sellers. The implication of this is that the firms in perfectly competitive industry will earn normal profits in the long run as supernormal profit earned by the firms in the short run will be depleted by the entry of the new firms into the industry. It is relatively easy to lease a plot of land to grow wheat and in the event that the farmer chose to give up wheat farming, he could easily terminate his lease with the landlord. The start up cost is low as all he needs are some simple tools and seedlings. In oligopoly, there are significant entry and exit barriers. For example, in car production, there are very high initial fixed costs such as the setting up of the assembly line and only if the firm produces a very large output level will the average cost fall significantly. The lower cost associated with a big output serves as an entry barrier for new firms as their initial d emand is usually low. Exit is also difficult, as it is not easy to dispose of the firms fixed assets. Other forms of barriers could be patent rights, exclusive ownership of certain raw materials and legal barriers. So the oligopolist can earn supernormal profits even in the long run. 2b. Discuss why oligopoly is a more common type of market structure compared to perfect competition. (15) Perfect competition is an ideal model and so it is difficult to find markets that have all these characteristics. There are some markets in the real world that approximates perfect competition. Examples of such markets are farming, the stock exchange market and the foreign currency market. These markets possess some of the characteristics of PC as explained in part (a). However, even in such markets, some of the characteristics are hard to fulfil. For instance, buyers and sellers may not be price takers. In the stock exchange market, there are some individuals or institutions that can influence the price of shares through their large holdings of a particular companys shares. The product is also not homogenous if stock of different companies are considered., Thus, if they were to sell their shares, price will fall. Knowledge is not perfect either. Although buyers and sellers do have easy access to information through their brokers and the Internet, there are some who do have insider i nformation and use that to their advantage. Moreover, managers tend to reveal more information about their companies to financial specialists rather than to small investors. In the real world, most industries do not have that many firms. In fact, in industries such as automobiles, air-craft manufacturing industry, oil industry, steel industry, supermarket chains and pharmaceutical industry, the industry is dominated by a few large firms. Most firms would rather face less competition so that their market power can be consolidated and secured. Oligopoly is thus a more desired form of market structure as far as sellers are concerned. Oligopoly is a more common market structure. It can be attributed mainly to the high entry barriers. Barriers to entry refer to any impediments that prevent new firms from competing on an equal basis with existing firms in an industry. An effective barrier for new firms to enter the industry is substantial economies of scale. The production of some goods involves very high initial fixed costs. Good examples are the petroleum industry and the manufacturing of aircrafts. For example, Airbus and Boeing must construct huge expensive structures to build the A380. Thus, for the production of such goods, the larger the output the greater is the economies of scale enjoyed by the firm. Such industries have very large Minimum Efficient Scale, and hence, only a few firms exist in such industries. Economies of scale are not the only source of barrier to entry. Other barriers to entry can be the possession of superior technical knowledge or sterling reputation for quality or efficiency. Take for example, high end sports cars like the Ferrari is such well known brand names that it is quite impossible for any new auto firms to replicate them. For years, they are the symbol of quality and luxury, an image that the carmakers have painstakingly cultivated. Production of such cars also requires superior technical knowledge, which is jealously guarded by the manufacturers. Thus it is not easy for new firms to enter such industries. In addition, existing firms could have spent millions on advertising to build and maintain brand loyalty. It will require a substantial period of high advertising costs and low revenues for new entrants if they want to establish themselves. Also, they can spend large amounts on advertising to make it difficult for a new entrant to differentiate its product. With the high entry barriers, firms are able to earn supernormal profits in the long run and have the financial strength to block the entry of new firms. Such firms can also adopt predatory pricing to further keep out competitors. Their huge profits allow them to cut prices drastically to drive out competitors. They can maintain excess production capacity as a signal to a potential entrant that with little notice, they could easily saturate the market and leave the new entrant with little or no revenue. Besides, huge profits allow firms to spend generously on RD. The discovery of new and better products allows them to compete more effectively in the market and also keep out other firms. For instance, in the pharmaceutical industry, millions of dollars are required to discover a new vaccine or a new drug. Hence the presence of high entry barriers results in many oligopolies. Globalisation and liberalization With increased globalisation, many domestic firms are threatened by the entry of big foreign firms or MNCs. Bigger firms have a competitive advantage in terms of pricing. Domestic firms can survive as long as there is government legislation to prevent the entry of foreign firms. But most governments are liberalizing their domestic industries. In order to compete with foreign firms, domestic firms have to merge. A merger would safeguard their survival as well as to allow them to compete more effectively. For instance, the merger of DBS bank with POSB and UOB with OUB , are all meant to expand the size of each bank so as to better compete with other international banks such as Citibank and Standard Chartered etc when MAS liberalize the financial sector to encourage competition. Hence globalisation has increased the tendency for mergers and the formation of oligopolies. Conclusion There are not many industries in the real world that satisfy the characteristics of the perfectly competitive model given it is an ideal model. On the other hand, the characteristics of an oligopoly are more easily met. The nature of production is more favourable to an oligopolistic kind of market. There are many advantages to being big. Some firms are big due to high entry barriers natural or man-made, while others expand internally or externally through mergers and acquisition in response to a changing external environment. The main reason for oligopoly being a common market structure can be attributed to benefits of economies of scale which gives firms the incentive to merge and be large. It will lower their costs and give them higher returns to meet potential competition and as a consequence, they have huge incentives to erect barriers to deter entry by new firms, and to consolidate their position.

The Role of the Friar in William Shakespeares Romeo and Juliet :: William Shakespeare, Romeo and Juliet

The Friar directly and indirectly took part in suicide, murder, and other tragic happenings. The Friar is an honored man, who sells herbs and medicines to the people of Verona. He is a type of ancient pharmacist, who has potions for both causes of good and evil. There are three specific instances of the Friar playing a major role in Romeo and Juliet: the impossible marriage of Romeo and Juliet, Juliet's "death" plan, and Romeo's death. Without the Friar many crucial and tragic events would not have happened in Romeo and Juliet. The forbidden wedding of Romeo and Juliet could not have happened without the Friar. First of all, the Friar impulsively agreed to marry Romeo and Juliet, even though he knows it will cause later problems. In the beginning, the Friar thinks that "...this alliance may so happy prove; To turn your households' rancor to pure love." (II iv 91-92) Which shows that the Friar has a slight hope of their marriage possibly working. Consequently, at first, he shows no reluctance to marry the two controversial lovers. However, as time moves on, the Friar lets on that he has regrets about the marriage. The Friar feels that "Too swift arrives as tardy as too slow." (II vi 15) In other words, the Friar means that he senses that this whole wedding is happening too fast and he radiates a feeling of second thought. If the Friar had thought this crucial decision through he may have prevented many future tragedies. Accordingly, the Friar knows all along that "These violent delights have violent ends" (I I vi 9) The Friar knows that this is an impossible situation, which if made possible by himself will without a doubt end up in tragedy in one way or another. Under these conditions, as the Friar predicts, Romeo sinks into a deep depression, as a result of the fact that he cannot see his wife. Romeo has a one-track mind that is focused on something he cannot have. Similarly, Juliet becomes depressed and is grieving over the reality of her and Romeo's separation. Without the Friar the two lovers would not have been married, which would have prevented both of these depressions and future problems to come. The Friar is responsible for many problems which have a snowball effect after he assists Juliet with her "death" plan. When Romeo and Juliet are at their lowest point of depression, and Juliet is expected to marry Paris, she needs an escape plan.

Personal Writing: The Evaluation Of My Coaches Essay -- essays researc

Personal Writing: The Evaluation of My Coaches Throughout my high school basketball career I experienced several different coaches. Every new coach brought a different approach to coaching. The varying techniques of coaching brought about different attitudes and expectations during practices and games. I found that during practice, coaches had either the nice-guy or the drill sergeant approach. They also had different methods of coaching during and after the games. Practices are very important to basketball. If you practice hard and take it seriously, your team can become successful. All of my coaches in high school took practices seriously. I basically had two different types of coaches when it came to practice. There was the drill sergeant type, which had the team line up in the same place every day to do our calisthenics before each practice. The team captain stood facing the rest of the team and lead us in various stretches and other warm-ups. The coach was very strict. No horse play or unnecessary talking or anything else we knew would make the coach mad. Coach would have us do drills having to do with the plays we ran during the game. If we made a mistake coach would stop us and make an example of whoever messed up. He would say, "Did everyone see what Bryan just did? That is what you should not do." He would then gripe a little and after that we would continue our practice. I feel that this method...

Question 1. The Role of Industrial Eng neeri g M â€Å"Industrial Eng ne ring is co cerned with the design, improvement and installation of integrated systems f men, materials and equipment.It draws upon specialized know dg and skills i math matical, physical and social sciences together with the principle and me hods of engineering analysis and design to specify, predict and evaluate the results to be obtained from such systems. † It can therefore be seen that industrial engineers are designers of management systems and industrial engineering approach integrates various approaches such as op erations research, systems analysis, behavioral science etc. towards the integrated design of organizations.In this book many industrial engineering techniques will be used in various units which help us in better management of production systems. Operations Management – An Overview The Role of Models yI Indian Institution of Indus ial En ineering (IIIE) has adopted the following definition of Industrial Engineering: G Methods and techniques of scientific managemen hav tremendous role to play in helping us to make rational and logical decisions the context of production and operations management.Through scientifi m h ds to ls and techniques of industrial engineering and operations research along with behavioral science we can look at all facets of the problems and evaluate the onsequ nces of our actions before arriving at a decision. These techniques thu reinforce the s bjective or intuitive judgment and contribute to better management N O The scientific method for Operations management is growing pop arity because it allows for organizational decisions—whether by b siness or government—to be formulated under more rigorous considerations.

Generally a mathematical model is preferred in decision-making because it tries to explain system's objectives and function in terms of decision variables subject to our control as well as non-controllable parameters due to environment or resource constraints etc. Thus a simplified form of a model is: E = f (xj, yi) Where E =Measure of effectiveness or objective function xj =Controllable (decision), variable, j = 1 †¦ yj =Non-controllable parameter, i =1 †¦ m Thus a model provides us a cause-effect relationship so that we can evaluate ur alternative courses of action on the basis of our objectives and choose an optim l (best under the circumstances) strategy to maximise our effectivene s Thus mod s provide a valuable tool to compare our options and thus improve the q lity of decisions and provide us a better insight into our decision rocess Howe r it must be noted that models are a means to achieve an end (bet r decisions) nd not an end in itself.We must choose a simple, valid and logical mo el of the dec ion situation. A large number of model based techniques have b en de loped in th subject called `Operations Research' (OR) which help in mathemat al con eptual sation of many decision-making problems relevant to production/opera ions management. Some very versatile and powerful techniques like linea prog ming queuing theory and simulation have been applied extensively to st dy various problem areas in production management. Some of these will be d cribed, though briefly, in appropriate units in this book.The Role of Computers M In a large sized problem, a computer becomes a very efficient tool in problem solving and evaluation of alternati es. A b g size linear programming or simulation problem can be efficiently solved on omputers. Due to fast developments in computering facilities and a plication oftware, many OR models can he implemented via computers. Compu rs also ha e tremendous role in management information systems to provide us ful, relev nt and timely information for planning, monitoring and co tro f production systems-thus providing decision support through informati n.The Role of B havioural Science Since people are integral part of our production system, understanding of human behaviour is very important so that managers can evaluate the consequences of their actions on human relations, morale, motivation and productivity. Supervisor's relationship with his subordinates, organisation structure, individual and group behaviour, work habits and attitude, incentives, participation in decision-making, performance appraisal sy stems have impact on worker morale and motivation. Behavioural science provides us some insight on these aspects and therefore has a role to play in production and operations management.

Explain the product selection and stages involved therein. Product selection is an ongoing process in any organisation. In fact, as the environment changes, as new technology is developed and as new tastes are formed, the product should benefit from these developments; otherwise what is perceived to have added value today may not be perceived as such tomorrow. For example, jute has been in use as a packing medium for a long time.However, with changes in technology and consumer taste, the same product is no more perceived to ave added value and therefore, its demand has reduced. M Produ ibi ity The product election process is a highly integrative process. Thus product function, cost, quality and reliability are some of the inputs to this decision. The producibility of a product/service measures the ease and the speed with which the output can be produced. The specialised equipment, specialised skills and specialised toolings, facilitate in switching production from one product to another etc. nd are thus important ‘ factors to assess producibility. It is also important to look at the complete range of products produced because a new product may either use the capacity of processes/sub-processes already established or may require the establishment of capacity of some processes/sub-processes. A family of-similar products is much yI Product selection is a strategic dec ion, thereby involves other functional areas like marketing, research and dev lopment and as well also the top management therein.The operation managem nt function provides vital inputs regarding the production of the product o se vice in the e decisions making. G Produc t selection is a strategic decision for any organisati n. Such decisi s a long term decisions and the organisation commits itself to the product/pro ucts selected for a long time to come. What products to produce-in w at form and w th what features-is very important because many other de sions- or example he technology used, the capacity of the productive system, the locat n of production facilities, the organisation of the production function the planning and control systems, etc. re dependent on this. The competitiveness and rofi bility o a firm depend in part on the design and quality of the products and serv es that it produces, and on the cost of production. The design of a product or service may make it expensive to produce and a change in design may make it possible to duce he same in a less expensive way. Similarly, one design of a produ or serv ce m y require large and expensive additions to capacity of some pro ess whereas a change in design may make it possible to produce the same with e isting c pacity. N O U A Strategic Decision M yI G N O U To download more solved assignments visit myignou. in The output ideas thus generated are then screened where their match with corporate objectives and policies is studied and their market viability is established. A detailed economic analysis is then performed to determine the probable profitability of the product or service. For non-profit organisations, this takes the form of a cost-benefit analysis. This is followed by development of the product or service from a concept to a tangible entity and finally by design and testing.No Smooth Sequence Although Figure I depicts product selection as a sequential process where one stage follows another, in reality, the process may not be so smooth as shown. Thus, economic analysis may have to be done after output development if reliab e cost estimates are not available at the earlier stage. Similarly, new product featur may be added at any of the above stages, thereb y initiating a whole new cycle. Final y as product selection is an ongoing process, there is no finality to the pr cess since as some new product ideas are being processed, still new ideas enter the utput sele tion process and this may go on and on.The product selection rocess herefo en ures a continuous match between what is demanded and what i produced. In some cases, the production process has also to be des gned along w h the product or service. This has to be done, for example, when the m ket viabilit of the product depends on low cost and so the production process h s to be decid d along with the product design. Or take the case of another product whe e it is felt imperative to obtain a large market share right from the in ial l h It may become necessary to establish a large capacity for the production pr cess right from the beginning.The production process has to be design d along with he product in such a case. The previous section highlig ted th fact th an output possibilit y has to cross several hurdles before it enters e market as a commercial product or service. The new idea mortality curve p esents e same in a graphical manner. Figure II shows the mortality curve for a hypothetical group of fifty chemical product-ideas. Although the p duct id s ar hypothetical, still the stage-wise mortality as well as the time frame sho n is quite i dicative.Figure II assumes that after three years of research fifty po enti chemica product-ideas are available for consideration. Initial scre ning r duces this number to about half and after economic analysis, by the end of year f ur the number of potential products decreases to nine. The mortality of deas continues over time and by the end of five-and-a-half years, at the completion of he product and process development stages, the number has already fallen to about five.Design and testing reduces this further to about three and by the end of construction, market development and commercialisation, just about one suc cessful product is left.. Figure 11 is based on international experience, and situation in India has not been tested empirically. Thus, the mortality curve should be treated as an indicative proposition in the Indian context. M yI G New-Idea Mortality Curve N O U 5 To download more solved assignments visit myignou. in M The curve also show that co verting product ideas into marketable products is a slow process.For chemical produc on an average it takes six years to commercialise a product after the ini al research has been completed, as is shown by Figure II. At the end of t all, a product ommerc ally launched may not turn out to be successful and the mortali y may exte d to the product as well. The actual figures in Figure †¢II are only indicative and within an industry firm's differ in the speed at which they can convert a product idea into a commercial product. Some organisations are more innovative than others and they are always ahead with more new product ideas.Similarly , some organisations are more risk-taking than others and attach a high priority to being a pioneer with new products than others who are relatively risk-averse and would like to do a more thorough job of screening, economic analysis, product development, design and testing and would perhaps also wait-it-out to see how some others have fared with similar products. =============================================================== yI G 6 N O U To download more solved assignments visit myignou. in Question 3. Define Job Design. How has management viewed job design since the industrial revolution?JOB DESIGN is the process of putting together various elements to form a job, bearing in mind organizational and individual worker requirements, as well as considerations of health, safety, and ergonomics. The scientific management approach of Frederick Winslow Taylor viewed job design as purely mechanistic, but the later human relations movement rediscovered the importance of workers' relationsh ip to their work and stressed the importance of job satisfaction. Job design refers to the way that a set of tasks, or an entire job, is organized. Job design helps to determine.It takes into account all factors which affect the work, and organizes the content and tasks so that he whole job is less likely to be a risk to the employee. Job design involves administrative eas such as: job rotation, job enlargement, task/machine pacing, work breaks, and work ng hours. A well designed job will encourage a variety of ‘good' body posi ons, have re sonable strength requirements, require a reasonable amount of mental activ y and he p foster feelings of achievement and self-esteem. Job design refers to the way that a set of tasks, or an ent e job, is orga ized.Job design helps to determine: what tasks are done, how the tasks are done, how many tasks are done, and in what order the tasks are done. It takes into account all factors which affect e work and organizes the content and tasks s o that the whole job is less like to be a risk t the employee. Job design involves administrative areas such as: job rotation, job enlargement, task/machine pacing, work breaks, and working hours A well designed job ill encourage a variety of ‘good' body positions, have reasonable streng requirem nts, require a reasonable amount of mental activity, and help foster feelings of achie ement and self-esteem.In productio and operations, Job design follows the planning and designing of product, process, and equipment. Job design specifies the content of each job and determines how work is distributed within the organization. Management viewed job design since the industrial revolution in the approaches to Job Design USING SOCIO TECHNICAL SYSTEMS There are three important approaches to job design, viz. , Engineering approach, Human approach and The Job characteristic approach. Engineering Approach M yI G N O U To download more solved assignments visit myignou. in The most important s ingle element in the Engineering approaches, proposed by FW Taylor and others, was the task idea, â€Å"The work of every workman is fully planned out by the management at least one day in advance and each man receives in most cases complete written instructions, describing in detail the task which he is to accomplish . . . This task specifies not only what is to be done but how it is to be done and the exact time allowed for doing it. The principles offered by scientific management to job design can be summarized thus: †¢ †¢ †¢ †¢ †¢ Work should be scientifically studied. As advocated fragmentation and reutilization of work to reap the advantages of specialisation. Work should be arranged so that workers can be efficient. Employees selected for work should be matched to the demands of the job. Employees should be trained to perform the job. Monetary compensation should be used to reward succes ful performa ce of the job. Two types of facto viz. ) motivator s like achievements, recognition, work itself, responsibility, d anceme t a d growth and (ii) hygiene factors (which merely maintain the employee o th job and in the organization) like working conditions, organisational polici inter-personn l relations, pay and job security. The employee is dissatisfied with the job f maintenance factors to the required degree are not introduced into the job. But, the employee may ot be satisfied even if the required maintenance factors are provided. The employe will be satisfied with his job and he will be more productive if motivators are introduced into the job content.As such, he asserts that the job designer has to introduce hygienic factors adequately to reduce dissatisfaction and build motivating factors. Thus, THE emphasis is on the psychological needs of the employees in designing jobs. The Job Characteristics Approach M yI G The human relations approach r cognised the ed to design jobs in an interesting manner. In the past two decade much w rk has been directed to changing jobs so that job incumbents can satisfy th r needs for growth, recognition and responsibilility, enhancing need satisfactio through what is c lled job enrichment.One widely publicised approach to job enrichment ses w t is alled job characteristics model and this has been explained separately n the nsuing section. N Human Relations Approach O These principles to job design seem to be quite rational and appeal g bec e they point towards increased organisational performance. Specia isation and outinisation over a period of time result in job incumbents becoming exper rather quick y, leading to higher levels of output. Despite the assumed gains in fficien y, behavi ural scientists have found that some job incumbents dislike specialised and routin j bs. UThe Job Characteristics Theory states that employees will work hard when they are rewarded for the work they do and when the work gives them satisfaction. Hence, they suggest that motivation, satisfacti on and performance should be integrated in the job 8 To download more solved assignments visit myignou. in design. According to this approach, any job can be described in terms of five core job dimensions which are defined as follows: (a) Skill variety: The degree to which the job requires that workers use a variety of different activities, talents and skills in order to successfully complete the job requirements. b) Task identity: The degree to which the job allows workers to complete whole tasks from start to finish, rather than disjointed portions of the job. (c) Task significance: The degree to which the job significantly impacts the lives of others both within and outside the workplace. (d) Autonomy: The degree to which the job allows workers freedom in planning and scheduling and the methods used to complete the job. (e) Feedback: The degree to which the job itself provides workers with lear, direct and understandable knowledge of their performance.M Question 4. ============== = =============================================== Discuss the va iation in the approach of planning and controlling of mass, batch and job shop production. Mass production (also called flow production, repetitive flow production, series production, or serial production) is the production of large amounts of standardized products on production lines. It was popularized by Henry Ford in the early 20th century, notably in his Ford Model T. yIJobs that are high on motivating potential m st be h gh at least in one of the three factors that lead to meaningful work an must b hig in both autonomy and feedback and vice versa. These three critical psyc ological sta s lead to the outcome such as (a) high internal work motivation, (b) high gr wth satisfaction, (c) high quality work performance, (d) high general job satisfaction, (e) high work effectiveness and (f) low absenteeism and turnover The odel says that internal rewards are obtained by an individual when he learns t at he personally has performed well on a task that he cares about.G N The core job dimensions can be combined int a sin le predicti e index called the Motivating Potential Score. Its computation is as foll ws: Motivating Skill variety + Task identity + Task signific nce potential = x Autonomy x Feedback score O U All of the job dimensions impact workers psychologically. The irst three dimensions affect whether or not workers view their job as meaningful Autonomy determines the extent of responsibility workers feel. Feedback allows for eelings f sati facti n for a job well done by providing knowledge of results.

This permits very high rates of production. Mass production is capital intensive, as it uses a high proportion of machinery in relation to workers. With fewer labour costs and a faster rate of produ ction, capital is increased while expenditure is decreased.However the machinery that is needed to set up a mass production line is so expensive that there must be some assurance that the product is to be successful to attain profits. Machinery for mass production such as robots and machine presses have high installation costs as well. Thus, mass production is ideally suited to serve large, relatively homogeneous populations of consumers, whose demand would satisfy the long production runs required by this method of manufacturing. As such, it is not surprising that, given a number of other factors, mass producti n first became prevalent in the United States.One of the descriptions of mass production is that the craftsmansh is in the wo kbench itself, not the training of the worker; rather than having a skilled wo ker measu e every dimension of each part of the product against the plans r the o her pa ts as it is being formed, there are jigs and gauge blocks that are ready t hand to e sure that the part is made to fit this set-up. It has already been checked hat the finis ed part will be to specifications to fit all the other finished parts – a d it w l be made quicker, with no time spent on finishing the parts to fit one another.This the sp cializ d capital required for mass production; each workbench is different and eac set of tools at each workbench limited to those necessary to make one p t. A ch of these parts is uniformly and consistently constructed, interchangeability o components is thus another hallmark of mass produced goods. Mass production systems are us ally organized into assembly lines. The assemblies pass by on a conveyor, or if they are h avy, hung fr m an overhead monorail. In a factory for a complex produc rather han one assembly line, there may be many auxiliary assembly lines feeding sub-assemblies (i. . car engines or seats) to a backbone â€Å"main† assembly line. A di gram of a typical mass-production factory looks more l ike the skeleton of a fish than a sing e line. Batch production i a manufa uring method used to produce or process any product in batches as opposed a conti uous production process, or a one-off production. The primary ch racter stic of batch production is that all components are completed at a workstati n befo e hey move to the next one. Batch production is popular in bakeries and in the manufacture of sports shoes, pharmaceutical ingredients, inks, paints and adhesives.In th manufacture of inks and paints, a technique called a colour-run is used. A colour-run is where one manufactures the lightest color first, such as light yellow followed by the next increasingly darker colour such as orange, then red and so on until reaching black and then starts over again. This minimizes the cleanup and reconfiguring of the machinery between each batch. White (by which is meant opaque paint, not transparent ink) is the only colour that cannot be used in a colour run due to the fact that a smal l amount of white pigment can adversely affect the medium colours.M yI G N O U 10 To download more solved assignments visit myignou. in There are inefficiencies associated with batch production. The production equipment must be stopped, re-configured, and its output tested before the next batch can be produced. Time between batches is known as ‘down time'. Batch production is useful for a factory that makes seasonal items or products for which it is difficult to forecast demand. Batch production has many â€Å"pros† and â€Å"cons† but is effective and used worldwide, mainly by larger businesses on higher profit margins.There are several advantages of batch production; it can reduce initial capital outlay because a single production line can be used to produce several products. As shown in the example, batch production can be useful for small businesses who cann t afford to run continuous production lines. Also, companies can use batch production as a rial run. I f a retailer buys a batch of a product that does not sell then the producer an cease production without having to sustain huge losses. The term Job Shop Production (JSP) describes a m nufact ing e viro ment that produces piece goods in small batches.It is a common manufactu ing environment in small and medium-sized enterprises (SMEs). The inc ming orders often differ in the number of ordered products, their design, process charac ristics (for example, routeings, operation processing times, and set up times), or ur ency. Becau of this variation the control of the material flows in this type of compan s is extremely complex. It can hardly be predicted how the production o ers ill be vided across the machines in future periods. A high demand on machines nd varying production orders cause long waiting times of orders on the shop floor.The d rect consequence is that lead times are long and unreliable, whereas nowadays sho nd rel able delivery times are required. Most of the problems in j ob pro uction a ise fr m the variety of jobs arriving and demanding individual processing equences on the scarce facilities in the job shop. Owing to these factors the jo shop chara erized by the following typical problems: complicated and unsystematic material flow patterns large in-process inventorie large waiting times for jobs large completi n times f r jobs unpredictable p ob ms owing o the large variety of tasks M Question 5Discuss the various methods for stores accounting and verification systems. Stores Accounting Systems Stores accounting is important from the point of view of estimating the cost of the product for pricing decisions. The costing of material has to be done both for the materials consumed in the production and estimating the value of materials held in stock. For the purpose of costing the receipt of materials, the factors that should be included yI G N O U 11 To download more solved assignments visit myignou. in are material price, freight charges, insurance, duties, taxes, packaging charges etc.The prices quoted and accepted in purchase order may often be stated in various ways such as net prices, prices with discount terms, free on board, cost, insurance, freight, etc. All these factors should be appropriately accounted while costing for the incoming materials. Another important accounting is to be done for the issue to production and of the stocks held at the end of accounting period. Let us discuss some of the important and frequently used system for this purpose: a) FIFO System: This system known as First in First Out System is based on the assumption that the oldest stock is depleted first.Therefore, at the time of issue the rate pertaining to that will be applied. There is no `profit' or `loss' in the p icing arrangements. The value of the stocks held on hand is the money that has be n paid for that amount of stock at latest price levels. In case of too many changes in pr e levels the FIFO System becomes unwieldy. Another limitat ions of is system is at it fails to provide a satisfactory answer to costing-returns from stores. ) LIFO System: This system known as `Last in First Out' System i based on the assumption that the most recent receipts are issued first As the lastest prices are charged in this system, it leads to lower reported p ofits i the periods of rising prices and this offers savings in taxes. In case of wide fluct tions pric s this system tends to immunise unrealised gains or losses in invento y It has almost the same limitations as that of FIFO System. c) Average Cost System: This is b sed on the as umption that issues to production department are equally made from different ipmen s in stock, i. . an average cost of shipment in stores is charged t stabili es th cost figures. The average is to be calculated by dividing the total co t with the n mber of items and is to be updated with every new purchase. d) Market Value System: This is lso known as replacement rate costing, in which the material s issued are char ed the prevailing market rates. This system underestimate e stock n h nd in the case of price increase, whereas it overestimates the s ck on han in the case of price decrease. This may in turn lead to writing off huge mo t to mak it realistic.Moreover, a continuous monitoring of the ma ket tes for all materials makes the system cumbersome. e) Standard Cost System: In this system a detailed analysis of market price and trends is carrie out to determine a standard rate for a fixed period, say six months or so. This standard rate is charged to materials issued during this period irrespective of the actual rate. After the period is over the standard rate is reviewed and updated. This system reflects the efficient use of materials as the fluctuation in rates is not considered in accounting. Moreover, it adds to clerical efficiency as the fresh rates are not to be obtained every time.However, similar to Market Value Approach, this also leads to underestimating or overest imating stocks on hand in case of rising and falling prices respectively. f) System of Costing the Closing Stock: The general guideline for this purpose is to M yI G N O U 12 To download more solved assignments visit myignou. in use market price or stock at cost, whichever is less. : The cost of closing stock is governed mainly by price units, obsolescence and deterioration. In rare cases the stock may appreciate with time. Appropriate formulae to account for these factors should be developed keeping in view the past experience.Stock Verification Systems Some discrepancies between the actual and the book balances of inventories are bound to occur despite the diligent store keeping. The process of stock verification is carried out for following purposes: i) To reconcile the store records and documents for their accuracy and usefulness, ii) Identification of areas deserving tighter document control, iii) To back-up the balance sheet stock figures, and iv) To minimise the pilferage and fraudulent practices. Most companies keep an â€Å"inventory short and over† account to abs b such discrepancies, which is eventually closed into the manufacturing overh ads account.Some of the systems of physical stock taking are as follow : a) Annual or Periodic Physical Verification: In this system the entir inventory is physically verified at the end of a period, usually t e accounting period. That is, normally at the end of fiscal year. Stocks are closed f r a fe days This may necessitate the shut down of production operations;. ‘ th activities such as repair and overhaul of equipment and machinery are r orte A s cial crew of store inspectors and stores verifying officers, usually from the material audit, physically check each item and compare the e tries on bin c rd and stores ledger.This leads to the formation of a list of surplus r short ite Dam ged and obsolete items are traced and recorded. This needs o develop a de ailed programme and schedule to complete th e verifications storew se and item ise. Top management's sanction can then be sought for writing off defici ncies o valuing surplus. As all the items are checked at ne time there can be no confusion about any item being left unchecked. b) Perpetual n entory nd Continuous Stock Taking System: In case of large firms dealing w th large num er of items the final inventory system may take a lot of time and it may no e possib e to shut down the whole plant.The perpetual invent ry system i a more appropriate method for large plants. In this method the stock ver ficatio is done continuously throughout the year. Different methods are adopted by ifferent firms for continuous verification. Some firms div de the whole inventory into fifty-two equal parts. Each part is verified every week. Some firms record store balances after every receipt and issue, and a number of items are counted daily or at frequent intervals and checked with the bin cards and stores ledger. Discrepancies found, if any, o wing to incorrect entries, breakage pilferage, over-issue, placing of items in wrong bins, etc. are investigated and corrected accordingly. The significant advantages of this system are as follows: i) The shut down of the plant is not necessary for stock checking/taking. ii) The method is less costly, less tiring, less cumbersome and hence is more accurate. iii) Discrepancies and defects in stores are readily detected and are not carried over M yI G N O U 13 To download more solved assignments visit myignou. in throughout the year. This prevents damages and losses. iv) Slow moving stocks can be noted and proper action can be initiated in time. v) The stock items are kept within the limits. ) Low Point Inventory System: Some companies take the physical inventory, i. e. the stock level of stores is checked generally when it reaches its minimum level. Question 6. Write Short notes on: a) Work Sampling Work Sampling is a fact-finding tool. It is a measurement technique for quantit ive a nalysis, in terms of time, of the activity of operators, machines, or f any observ ble state or condition of operation. This tool is particularly useful when inf rmation urgently needed about men or machines, especially in the analysis f non-r p titive or irregularly occurring activity where no complete method and frequen y description is available.Work sampling can be used to study almost a y type of wor : repetitive and non-repetitive, factory or office, executive or supe visory, clerical or ngineering, handlers, salesmen, nurses and what have you. a) Some uses of Work Sampling Work Sampling provides a w y to: †¢ †¢ †¢ †¢ †¢ †¢ †¢ †¢ †¢ †¢ M yI obtain information bout ei er certain long cycle work or nonrepetitive type of jobs for which it would be clearly impractical to use continuous observ i n methods i dicate if certa activit es should be studied in detail. elp sign the work load distribution in formulating a new work system. t u y any op ration for possible methods improvement. help e tablish job content as an aid to job evaluation and employment purposes. aid supervisors to organise their time. aid appraisal of shop effectiveness, efficiency, safety performance etc. provide feedback information about compliance to stated management policies. assist in establishing standards of performance. establish controls on labour, material or machine utilisation. G N Work sampling is a method of randomly obs rving k ting state or condition of the object being studied.From the proportions f observations in each category, inferences are drawn concerning th total work ac vity under study. It can be used for fact-finding, work measurem nt and m h ds analysis. O U The object of the observations maybe personnel, equipment or facilities which can be categorised as follows: 14 To download more solved assignments visit myignou. in Typical categories applied to people are (a) Working (b) Being idle (c) Being out of area (d) W alking (e) Handling material (f) Inspecting (g) Changing tools (h) Cleaning up (i) Handling clerical tasks (j) Talking.Typical categories applied to machines/equipment’s are: At work (b) Idle-no operator (c) Idle-no stock (d) Idle-being serviced (e) Idle interference. ——————————————————————————————————–b) Acceptance Sampling Acceptance sampling uses statistical sampling to determine whether to acc pt or reject a production lot of material. It has been a common quality control techniq used in industry and particularly the military for contracts and procuremen It is usually done as products leave the factory, or in some cases even within the fac ry.Mos often a producer supplies a consumer a number of items and deci on to a cept o reje t the lot is made by determining the number of defective items in a sample from the lot. The lot is accepted if the number of defects falls below where th acceptance n mber or otherwise the lot is rejected. One of the powerful statistical techniques of quality ontrol is Acceptance Sampling. This technique is generally used in those si atio where items are inspected in batches, generally known as lots.The acceptability w l depend on the acceptable quality of the lot, which in turn depends on the u e and the pric you are willing to pay for this quality. Acceptance is based on the infe ence mad from th sample and hence the technique is known as Acceptance Sampling Typically a lo is specified by its size and the fraction of defectives that are expected to e present ( t the most) in the lot. The principles of statistics are used in the infe nce p cess One of the powerful statist al tech iques of quality control is Acceptance Sampling.This technique is generally sed in those situations wher e items are inspected in batches, gener l y know as l ts. For example, you may receive a shipment of 10,000 electric bulbs and y u may ha to decide whether to accept the shipment or return it back to the suppl er. T e accept bility will depend on the acceptable quality of the lot, wh ch turn depends on the use and the price you are willing to pay for this quality. S ppose you decide to accept if the average fraction defective is less than 5 per cent. Th n to ascertain the actual quality you may decide to inspect each acid every bulb.Su h a strategy of. 100 per cent inspection, however, may often be expensive and impractical. In such cases a more intelligent way is to use the concept of Sampling Inspection. ——————————————————————————————————-c) Value Engineering & Analysis Value Engineering or value analysis is a systematic method to improve the â€Å"Value† of goods and services by using an examination of FUNCTION. Value, as defined, is the M yI G N O U 15 To download more solved assignments visit myignou. in ratio of Function to Cost.Value can therefore be increased by either improving the Function or reducing the cost. It is a primary tenet of Value Engineering that quality not be reduced as a consequence of pursuing Value improvements. Value Engineering is sometimes taught within the industrial engineering body of knowledge as a technique in which the value of a system’s outputs is optimized by crafting a mix of performance (Function) and costs. In most cases this practice identifies and removes unnecessary expenditures, thereby increasing the value for the manufacturer and/or their customers.Value Engineering uses intuitive logic (a unique â€Å"how† – â€Å"why† questioning technique) an d the analysis of Function to identify relationships that increase Value. It is considered a quantitative method similar to the Scientific Method, which focuses n Hypothesis Conclusion to test relationships, and Operations Research, which uses mod l building to identify predictive relationships. A viable Value Engineering Program is predicated upon an adequa return on investment, typically 1% of total obligated authority for DLA activitie Benefits include: Reduced acquisition costs. Reduced life cycle costs.Reduced total ownership costs. Standardization, simplification or el BEST VALUE!

Design This is the stage that most VE participants are used to becoming involved, when the design has at least made it to the schematic stage. The primary tool available to the VE 16 To download more solved assignments visit myignou. in team is the Workshop—typically a 40-hour session (or less for smaller or less complex projects).The Workshop is an opportunity to bring the design team and client together to review the proposed design solutions, the cost estimate, and proposed implementation schedule and approach, with a view to implementing the best value for the money. The definition of what i s good value on any particular project will change from client to client and project to project.

When combined with crude statistical process controls, this assures that less than one in a million parts will fail to fit. ————————————————————†”—————————————-d. Waste Management. yI lue Engineering During this phase value engineering is still possible thr ugh the use of Value Engineering Change Proposals (VECP). Contractors can be p ided onetary incentives to propose solutions that offer enhanced value to the owner, and share in the financial benefits realized. Clearly the owner must c nsider contra tor-generated proposals very carefully, from a life-cycle perspective and a liability p rspect ve.The A/E team must be brought in to the decision-making proces to agr e to he proposed change as not having any negative impact on the overall de ign and buil ing function. The evaluation of a VECP is treated similarly to any cha ge ord r during construction, with issues such as schedule and productivity impacts bei g considered along with the perceived cost savings generated.

A properly-designed and well-managed landfill can be a hygieni and elatively inexpensive method of disposing of waste materials. Older, poorly-de igned or poorly-managed landfills can create a number of adverse envir menta impacts such as wind-blown litter, attraction of vermin, and generation of iq d leacha Another common byproduct of landfills is gas (mostly composed of methan and carbon dioxide), which is produced as organic waste breaks down n robical y.Th gas an create odor problems, kill surface vegetation, and is a greenho se gas =======================xxx======xxxx============================ yI G N Waste management practices differ for developed and d veloping na ions, for urban and rural areas, and for residential and industrial, produ ers.
