Abstract
This paper discusses system development life-cycle (SDLC), an approach to developing an information system or software product characterized by a linear sequence of steps that progress from start to finish without revisiting any previous step. The author points out that the SDLC model is a project management tool, which is used to plan, execute, and control systems development projects. The paper reviews many models, including the Waterfall Model, which is built upon the basic steps associated with SDLC using a ?top-down? development cycle in completing the system and represents a traditional type of SDLC.

From the Paper
"Disadvantages identified by Walsham (1993) in relation to the Waterfall Model include that change to contract and costs must be renegotiated if such changes are made once construction has been initiated. As well, users must wait until the end of the project or until at least a major portion of it is complete, before observing the results. Finally, the early phases of the project often take much longer due to the time necessary to generate the detail necessary in the SSD. According to Kay (2002), another major problem associated with the Waterfall Model is that it assumes that the only role for users is in specifying requirements, and that all requirements can be specified in advance."

Abstract
This paper attempts to analyze a work-related project that uses a systems analysis tool for the implementation of a specific business or information system. The paper focuses on the use of the System Development Life Cycle (SDLC) to implement a business or information technology need, as well as the implications associated with the development of an internally used software package. The paper provides insights into International Lumberyards, Inc., implementation, information-gathering, and other techniques used for various aspects of the reengineering project. The System Development Life Cycle is evaluated to determine if it has been successful or if there were obvious failures in the efforts to institute the concepts of "Business Process Re-engineering" or "Work-flow Management".
From the Paper
"The true problem of almost all businesses today revolves around the fact that all aspects of industry have been put into a position of forced efficiency by technology such as b2b and other e-business advances. In addition, the ever increasing demands of the highly competitive global economy will continue to keep all businesses under this pressure.
The goal of the business community will need to be to always establish methods or processes that allow for more capitalization. "A new technology infrastructure, aligned with the business strategy, will allow for future growth as well as addressing the limitations of the current environment." (Grabski, 2002)"

Abstract
The Systems Development Life Cycle (SDLS) has historically been a very useful tool in the development of software and operating systems in computer information technology. The five phases performed within a linear pattern of a SDLS are: Planning, analysis, design, implementation, and maintenance. This work gives a detailed analysis of each of these five phases and demonstrates ways in which the linear system is effective and how it has been used to develop new systems and subsystems that have greatly influenced the world of technology and business. Lastly, it briefly discusses possible alterations to the system and some shortcomings seen in the implementation of its use over the years.
From the Paper
"Many designers would consider the most crucial and exciting phase of the life cycle to be the design phase. This is where the on-paper theories are put into proposed code. The design team takes the planning and analysis, goals and guidelines for purpose and use and begins the development stage. During this phase the design team describes features to be performed in greater detail, they describe scream composition, apply rules of business, write countless diagrams describing functions and processes and begin documenting the first phase of code, called pseudocode, or theoretical code. It is from this paper trail that the development of the next phase begins."

Abstract
This paper presents many reasons for the failure of the American public education system. The author believes that it is only a matter of time before this antiquated and destructive way of conducting the educational business of America's students forces the United States to seek other ways to educate their children. The paper concludes that the educational system as it exists today is in so much trouble that the federal and state governments must quickly and deliberately seek new options to alleviate this frightening social condition.

From the Paper
"An additional factor which has greatly led to the breakdown of the American public educational system is the teaching methods and pedagogical philosophies applied by teachers and educators. Dr. Wilson lists three primary traits which have decreased the functionality of the public school system--first, "a highly authoritarian system that forces children to learn at a pace, a time and in an order determined by the teacher's convenience" (2006, Internet) which indicates that teachers rely much too heavily on antiquated teaching methods and naturally assume that all students learn best in a classroom environment with their peers."

Abstract
This paper discusses the modern welfare system as it exists in America and describes how it grew out of the cataclysm of the Great Depression. It looks at the division between social insurance and welfare to an increasing emphasis on disability. The paper suggests that welfare in America came from the uncertain efforts to match European states which had far more advanced systems.
From the Paper
"The Clinton administration forced a number of changes to the welfare system through executive action, requiring teen mothers on welfare to stay in school and requiring mothers to identify the fathers of their children as a condition to receiving welfare. These actions were intended to contribute to the education of welfare recipients and to hold men accountable for child support. To pressure non-paying parents, the administration used federal law enforcement against people trying to avoid child support by crossing state lines. These efforts did manage a change in the welfare system, with significant reductions of the number of people on welfare and increases in child support collections (Clinton)."

Abstract
This paper explains that, according to astrophysicists, society may never have a way of accessing any information about anything that occurred prior to the first milliseconds after the Big Bang; therefore, the truth of whether or not any God or Creator is responsible for the existence of the universe and life may never be known for lack of necessary data. However, the author continues, many 20th century philosophers believe that the harmony of nature proves the existence of a creator. Nonetheless, presently, the paper underscores, there is simply no logically sound argument to suggest that the existence of any God or Creator is even one iota more likely than not to be true.
Table of Contents:
Introduction
Analyzing the Issue Is Impossible because it Lies Outside the Realm of Human Intellect
The Mere Fact that We Exist Is Proof that a Creator Exists and the Inability to Explain Spontaneous Creation Proves that a Creator Is Necessary
Increasing Complexity Violates the Second Law of Thermodynamics
The Universe Could Not Have Come into Existence from Nothing
The Harmony of Nature Proves the Existence of a Creator
Conclusion
From the Paper
"Answering the question by reference to a God or Creator simply raises the exact same logical problems about the Creator: (1) if the self-creation of the universe is impossible, a self- created God is equally impossible; if spontaneous origin of the universe is impossible, a spontaneously originating Creator is equally impossible; and if the reality of the mechanism behind the origin of God is too complex to understand, it does not in any way explain or solve the perplexing problem about the existence of the universe."

Abstract
This paper is a look in to the improbability of extra-terrestrial life. The writer discusses the nature of extra-terrestrial life, SETI's inability to find any intelligent messages, the improbability of life on other planets outside of our solar system, and the improbability of life on planets within our solar system. This paper is designed to deny the existence of extra-terrestrial life, not affirm it.
From the Paper
"The search for extraterrestrial life has piqued the interest of humans for ages. Scientists have long looked for it, and the U. S. Government funds many searches. However, the only reason that scientists have for their search is probability--there is no hard evidence to support a possibility of life, only supposition. The actuality of extraterrestrial life is minimal for three key reasons: the inability of SETI to find any significant sign of life after years of searching, the improbability of life on planets outside of our solar system, and the improbability of life within our solar system."

Abstract
The paper explains that stars are set up to have planets circling around them and it is on those planets that scientists search to locate other life forms that may exist. The paper reveals that a growing body of scientists believe that there is/was life on Mars. The paper discusses how, with the advances in technology, it may not be long until we find a planet with living beings.

Conclusion
From the Paper
"Man has been working on science since the beginning of time. As the human race continues to evolve, technology become more advanced and the ability to answer questions accurately grows stronger. One of the questions that has continued to stump mankind since the beginning of time is whether or not there is life out there. Songs are written about it, movies depicting aliens abound and books convey the belief that there is life on other planets and in other solar systems, however, to date no scientific evidence has been found that can support that belief. The technological advances that have occurred in recent history have allowed man to provide a more structured research setting to answer the questions about life bearing planets and alien life."

Abstract
The paper looks at three U.S. states - Florida, California, and New York State - and examines the extent to which minorities are significantly over-represented in the penal system/detention facilities of these jurisdictions; because young people are the future of this country, and because youths who find themselves in trouble with the law early in life will undoubtedly fall into trouble later in life, as well, special attention is devoted to the experiences of minorities in the criminal justice systems of each of the three states. The type of approach the writer is pursuing in addressing this problem is, in its initial stages, two-fold: firstly, the available literature is reviewed to show that, without question, there is a serious problem that needs to be confronted; and, secondly, the paper looks at a variety of studies that suggest alternatives to the current conventional practice of merely "locking up" minorities who commit crimes without appreciating the sociological and economic factors that predispose them towards crime. As the third step of the proceedings, a comparative analysis is undertaken of the criminal processing records in each of the states mentioned above and whether or not minorities are more likely to be subjected to lengthy prison terms than whites who commit the same crimes.
