Abstract
This paper explains that a hazardous material emergency is any uncontrolled release or possible release of a hazardous material or substance that requires assistance from a local fire department or ?hazmat? team to control it. The author points out that the first steps for the incidence commander are to assess the situation, determine which level of magnitude the situation is (HAZMAT level 0, 1, 2, or 3), and then pass this information to whichever local, state, and federal organizations are required. The paper relates that air surveillance at the site of a hazardous material incident is vital to ensure that the personnel involved are not exposed to chemicals or materials in the air and that lingering particles do not contaminate local surrounding areas, placing the public in danger.

From the Paper
"Identifying materials in any hazardous materials accident is vital to site containment. Whenever there are unidentified products at a containment site, the incident commander must attempt to identify those products. First, visual inspection should be made to attempt to identify the materials. This can be done via binoculars if the materials appear to be corrosive to the eye. Additionally, the commander must look for the presence of smoke, vapor, or fire to help determine the chemical nature of the compound. The commander can also look for the original containers, to help identify the products."

Conclusion
From the Paper
"The first experimental demonstration of the piezoelectric properties in relation to crystal structure was published in 1880 by Pierre and Jacques Curie. This effect was considered quite important and was referred to as "piezoelectricity" in order to distinguish it from other areas of scientific phenomenological experience such as "pyroelectricity" (electricity generated from crystals by heating). As an aside, piezoelectrics also tend to be pyroelectrics. The Curie brothers did not predict that crystals exhibiting the direct piezoelectric effect (electricity from applied stress) would also exhibit the converse piezoelectric effect (stress in response to applied electric field). This property was mathematically deduced and hypothesized by Lippmann in 1881. The Curies then confirmed the existence of the converse effect, and continued on to obtain quantitative proof of the complete reversibility of mechanical deformations in piezoelectric crystals."

Abstract
This paper explains that the definition of green building principles is not absolute; however, the Integrated Waste Management Board of the state of California has several selection criteria for these materials: Efficiency of resources, indoor air quality, energy efficiency, water conservation and affordability. The author points out that another consideration for green building materials is that they are made and distributed by socially and ecologically responsible companies. The paper relates many produces; for example, a good material to use for the installation of exterior walls is structure-insulated panels, which are basically two outer skins of plywood or oriental strand board with an insulating filler, usually foam or straw, thus giving the benefit of reducing wood use, which is one of the lowest materials in terms of embodied energy, and preventing heat loss.
From the Paper
"As much as one wants to invest in environmentally friendly materials, they will never get the attention of the public unless they are considerably more durable than the less eco-friendly product. Durable items remain in service for much longer, and thus, less need for replacement or cycling. One such product is Ecoshake, a shingle made of recycled vinyl and wood fiber. It carries a half-century warrantee."

Abstract
This paper looks at how material requirements planning (MRP or MRPI) was developed in the 1960?s, to enable companies to calculate the number of different components necessary and when they were needed. It traces its development over the years and identifes the main differences between materials resource planning (MRP), its predecessor materials resource planning II (MRP II) and Enterprise Resource Planning (ERP) as well as the pro's and con's of the MRP II concept. Using a basic diagram, the three fundamental functions of MRP are explained which are netting, batching and time phasing.
From the Paper
"Distinguishing MRPII from the original MRP concept is a simple process. MRPI is simply the process of identifying the amount of components required and at what time they are required. This developed into closed loop MRP, which calculated the workload required to fulfil the orders and compared this to the capacity available. MRPII expands on this by calculating the cost of proposed MRP runs, this allowed managers to identify viable production-runs and allowed them further control over the operation. In calculating the costs MRPII works in the opposite direction to MRPI, it starts at the lowest level of the BOM and works its way up until the net-requirements of the finished product is determined."

Abstract
This paper describes the steps involved in the scientific method and gives some examples of the concepts involved in the idea. It describes some experiments which used scientific method, and defines what is needed to make a hypothesis.
From the Paper
"The scientific method consists of a number of logical steps that are taken to verify a process situation or scientific fact. It begins by the development of axioms and assumptions which are usually made on the basis of observations by the scientists, e.g., Vesalius made the first accurate description of the arterial and venous systems of the human body based on first-hand observations he gained from dissection of a number of human bodies. "The accuracy of observations gains..."

»
Click here to show/hide summary
Abstract
The paper examines how hazardous waste is an acute problem throughout the world. The writer proposes that there is no single solution to this problem and that it is unlikely that our modern, industrialized society will become waste-free. This paper defines waste and hazardous waste. It looks at how hazardous waste is produced and how it can impact the environment as well as human health. The paper includes strategies for minimizing both the volume and impact of waste. The paper concludes that an approach that combines source reduction, reuse, recycling and burying in sanitary landfills is needed in order to properly manage both hazardous and non-hazardous waste.

From the Paper
"Rene Descartes was a believer in the scientific method. His works often disagreed with the Catholic churches. He had a commitment to the scientific method with a vast array of other subjects. Mathematics was his greatest interest. Descartes wrote a text on physiology and psychology. He said that emotion was finally the physiological base and argued that the control of the physical expression of emotions controlled the emotions "

Abstract
The research presented in this paper closely examines hazardous waste, its production, transportation and storage, and any issues arising out of those processes or events that will help lend insight and understanding into this very important subject. The paper explains that hazardous waste is any product which necessitates a special process or treatment for disposing of the waste, or, if mishandled, the waste, such as asbestos, poses a threat and health hazard to people who come in contact with it. The paper points out that there were no international rules or laws governing the transfer of hazardous waste from one country to another, and in some instances the transfer was negotiated privately, without making the government of the receiving country aware of the transfer. The paper suggests that it is perhaps more important than ever, and a very good time to look at the issues of hazardous waste when people are concerned about issues such as global warming and preserving the natural environment. The paper concludes that the issue of hazardous waste is one that must be addressed, and addressed in a way that relieves third world countries and future generations of people of the burden of dealing with that problem.
Outline:
What is Hazardous Waste and Who Makes It?
From the Paper
"Third world countries are targeted as dumping grounds for hazardous waste because those countries are badly in need of cash. It becomes very unsettling from a safety and humanitarian perspective when one thinks of the little island of Haiti contracting to receive hazardous waste when that country is already dealing with the squalor of human waste and disease for which there are no adequate infrastructures like sewer systems, water delivery systems, housing, and other infrastructure that would facilitate the adequate and proper handling and treatment of hazardous waste."

Abstract
This paper studies "The Principles of Scientific Management," the definitive philosophical work of Frederick Winslow Taylor, published in 1911. The author assesses Taylor's philosophy, which is based on four principles: (1) developing the best work method for every job; (2) scientifically selecting and developing workers; (3) combining the best work method and the best workers to complete the task according to that method; and (4) co-operation of managers and non-managers. The paper concludes by looking at modern day examples of Taylor's philosophy in action, particularly in the franchise industry.
From the Paper
"Frederick Taylor was depicted as the "father of scientific management". Taylor believed it was the management of an organization that was the key to solving any industrial problem. He was one man that recognized that there was no incentive for workers to increase their productivity rate because they might just work themselves out of a job. He also believed that hourly or daily wages were also no incentive to increasing productivity. Most of the ideas in scientific management were already known before Taylor's time. Taylor's contribution was to combine them into one, all-inclusive philosophy. His definitive work was The Principles of Scientific Management, first published in 1911."

Abstract
This paper focuses on the epic topic of household hazardous waste. A thorough description of what household hazardous waste is and where it comes from is provided. Following this, a discussion of safe usage, storage, and disposal of these materials is presented. The paper examines what can happen to the environment when these waste products are not disposed of properly. Finally, the paper discusses why household hazardous waste does not receive the same scrutiny by governmental agencies as commercial and industrial hazardous waste.
From the Paper
"As mentioned, household products are considered to be hazardous if they have one or more of the following properties. If they are flammable or combustible, meaning they can be easily set on fire, they are deemed hazardous. If they are explosive or reactive, in such a manner that they can detonate or explode through exposure to heat, sudden shock, pressure, or interaction with incompatible substances, they are deemed hazardous. If the product is found to be corrosive, in that it exhibits a chemical action that can burn and destroy living tissues or other materials if it comes into contact with them, it is deemed hazardous. And, if the product is toxic, where it is capable of causing injury or even death if it is ingested, inhaled or absorbed through the skin, it is deemed hazardous ("Household Hazardous Waste Project")."

Abstract
This paper reviews Thomas Kuhn's book about scientific advances entitled "The Structure of Scientific Revolutions." The paper focuses on several key elements and definitions in the work, with an emphasis on the concept of the scientific paradigm. The reviewer then discusses the role of paradigms in scientific revolutions, citing Kuhn's theory that revolutions appear when an old paradigm is substituted by a new one. Finally, the paper presents Kuhn's view of the past, present, evolution and future of science. The reviewer further describes Kuhn's view of the importance of crises in facilitating the evolution of science. The review concludes that Kuhn 's theory of paradigm and paradigm shifts gives a revolutionary description of scientific progress.
Outline:
Thomas Kuhn's Concept of Paradigm
The Structure of Scientific Revolutions
The Past, Present, Evolution and Future of Science
Reference List
From the Paper
" First of all, Kuhn (1996) introduces the notion of "normal science", that is, according to him, the science that bases its research on previous research which is recognized as valid by a scientific community. (p.10) It is the structure of normal science that the book proposes to investigate. Furthermore, Kuhn (1996) argues that the most salient aspect of scientific evolution in time is the fact that science does not progress through leaps or through unrelated sets of investigations. On the contrary, scientific research is always conducted under a paradigm, or, to put it differently, all research is based on previous scientific data. The scientific paradigm can be defined as a certain common pattern in scientific research, or a certain set of accepted world views that are held as true for a period of time. The paradigm is thus a set of common beliefs about the world, based on past research. "

"Introduction
In modern American society scientific rationality appears to represent the supreme intellectual perspective. Science and its "logic" is often presented as the ultimate arbiter of truth and value. However there are perspectives quite critical of this "immaculate conception" of science and the scientific method. The analysis which follows will focus on the insights of Paul K. Feyerabend into the relationship between theory and reality and in the process suggest a more humble but hopefully more accurate definition of scientific logic.

Abstract
Thomas S. Kuhn's structural account on the production of scientific knowledge constructs a generalized picture of the process by which a science is born and undergoes change and development. This paper explains that for Kuhn, science is a social system. It looks at how Kuhn analyzes the structure of scientific revolutions using several key concepts. He uses the term paradigm for an archetypal experiment or problem solution that implicitly tells scientists how to look at the world. This paper discusses how Kuhn's thesis about scientific authority utilizes the notion of normal science which he defines as science that uses a past achievement as a model and guide for formulating and solving new problems about the world which are based on paradigms. In addition, scientific revolutions occur when one paradigm is replaced by another. The writer also explains that as a result, paradigms play an important role in both normal science and scientific revolutions.
From the Paper
"The production of scientific knowledge undergoes six main steps. The first is a pre-paradigm stage in which the natural phenomena that later form the subject matter of a mature science are studied and explained from widely differing points of view. Next comes the emergence of a paradigm, embodied in the published works of one or more recognized scientists, defining and exemplifying the concepts and methods of research appropriate to the study of a certain class of natural phenomena, and serving as an inspiration to further research by its promise of success in explaining those phenomena. The third stage in the development of scientific knowledge is a period of normal science in which theories are explored and scientific puzzles are solved. A critical stage is the discovery of natural phenomena that violate the expectations governed by paradigms. In this stage, new theories are designed to explain these anomalous facts and then an abrupt transition to a new paradigm takes place in which a new conceptual and methodological framework arises which replaces the old. The final stage in the structure of scientific knowledge is the continuation of normal science within the new paradigm. This continues until the whole process repeats itself."

Scientific Realism, 2002.
This paper looks at scientific realism and its critics.

Click here to show/hide summary
Abstract
This paper explores the fundamentals of the faith-based scientific ideology, scientific realism. The author takes a close look at the ideas and opinions of realists and anti-realists concluding that anti-realists, though many of their criticisms are valid, are often as likely to fall prey to the same lack of critical evaluation that they claim to plague scientific realism.
From the Paper
"Mach?s argument could have been improved if he failed to accept contemporary arguments for the existence of sub-molecular particles until evidence existed that proved him wrong. In doing so, he would evoke a methodology in modern thought that many find credible: that which holds that scientific realism lacks the weight of true evidence and is more the matter of opinion than of critical inquiry and objective thought.
Scientific realism is a faith-based scientific ideology, one that maintains that we are warranted in believing in the unseen if it is posited by best explained and most popular scientific theories, which dominate by sheer weight of authority. In this sense it creates a mutualistic error - in trusting the consensus of beliefs among others were are most likely to emulate their mistakes. While mired in dogma, we can?t purport to achieve paradigm changes in thought or in reaching a new and better methodology with which to evaluate and comprehend phenomena both material and immaterial. Although the discourse of empiricists remains of interest to us, it must be remembered that every new scientific idea that is posited as contrary to existing beliefs of the nature of science and existence faces not only critical inquiry but also the inertia maintained by generations of adherents that revere even the least factually justifiable ideologies."
