From the Paper "What do acids and alkaline truly have in common? The history of the understanding of an acid is relatively old. Dating back to the Roman Empire days, came the word that we derived acid from, acidus, meaning sour. Around the 1800s, French chemists erroneously believed that all acids contained oxygen, including the famed Antoine Lavoisier. Svante Arrhenius, a Swedish scientist in the mid 1800s and a Nobel laureate, did a few experimentations with acids, and came up with concocting a definitive, chemically sound definition of an acid. Later on, in the 20th century, the partners Bronsted and Lowry initiated theories about acids using and published the acid-based concept. The most pragmatic research of acids and bases came from the American chemist Gilbert Lewis. Ever since then, the idea of acids and base has been widely recognized, although the definitions of such terms have been rather controversial."
Abstract This paper explains that the concept of distance-based education has become one of the most dynamic and fastest-growing segments of both university and graduate level educations; even many educational institutions that once considered themselves to have long histories with traditional classroom-based learning have begun to expand their existing programs because of technology advances like the internet. The author points out that, although, in the past, it was often considered that students learned more in traditionally based programs than in distance-based programs, distance-based educational programs have been shown to be just as difficult as any brick and mortar classroom setting and, in many instances, may actually offer more of a challenge than traditional counterparts. The paper states that success measurements should be getting students enrolled and successfully through the program plus surveys of students and teachers regarding the ease of use and system reliability.

From the Paper "The world has adjusted to the internet. Consider that local area networking and the internet has changed life to a point where a music download site like KaZaA has approximately one hundred sixty million users worldwide that have downloaded some version of the company's proprietary software. America is now at point where almost all business people are required to check daily emails and their children download internet music and housewives bargain shop on eBay. The advances in technology like file swapping are skills now just taken for granted. The individuals who take these skills for granted are the potential students for a program like this."

From the Paper "American education has evolved tremendously between the original one-room schoolhouse of the 19th and early 20th century to it modern incarnation. Instead of combined classrooms for primary and secondary school students, the contemporary American public education system provides progressive, graduated, age-appropriate instruction through the final year of secondary education. The first generation of American students used a single textbook, often sharing it with another classmate. Even throughout most of the last century, students in every grade still used the exact same textbooks as preceding class and the texts themselves updated only after a decade or more of use; in many instances, it was not uncommon that students used the same textbooks as had their parents."

Abstract This paper presents the author's perspective in "Activity Based Management for Service Industries, Government Entities and Non-Profit Organizations". The paper shows how the book focuses on providing information to managers that is vital to modern business concerned with cost management. Specifically, the book discusses activity based systems (ABS) that examines company profits in relation to activities generated by the organization.
From the Paper "The Author's Perspective: Activity Based Management Activity Based Management for Service Industries, Government Entities and Non-Profit Organizations focuses on providing information to managers that is vital to modern business concerned with cost management. The book discusses Activity Based Systems (ABS) that examine company profits in relation to activities generated by the organization. This process blends into the concept of Activity Based Costing (ABC), which allows management to comprehend profits that are derived from products currently in the market. As these elements are focused upon, Activity Based Management (ABM) then proceeds to determine which factors contributing to the organization are effective, and where costs can be reduced through Activity Based Budgeting (ABB). Proper budgeting through this system allows managers to plan the finances of the organization in a manner that will align the company with the competition, and provide for a stronger economic future (Brimson & Antos)."
Abstract This paper defines community-based policing and further shows how these programs can be implemented. A brief description of the traditional model of a law enforcement organization is presented. The author argues that this model has failed and cites research to support his argument. Community-based policing is suggested as a workable and positive alternative. The paper describes the specific training needed to implement community-based policing programs.
From the Paper "Law enforcement agencies have by tradition been structured as top-down, para-military organizations. Employees, sworn and civilian have been given limited autonomy and authority in these traditionally structured organizations. Although the conventional police organization structures allowed for greater control and accountability for employees, many politician and police leaders are incapable of responding to the new and changing demands that society make on law enforcement agencies see this organizational structure. In an effort to reduce crime and the fear of crime in their communities, many law enforcement agencies have embraced the philosophy of Community Based Policing. This policing philosophy emphasis the need for employees to use problem solving and the utilization of community resources to resolve community identified problems, reduce crime and the fear of crime."

Abstract This paper considers the advantages and disadvantages of having a home-based business and the critical success factors associated with the business. It looks at the growth and popularity of home-based businesses.
From the Paper "Late-night infomercials advertise home-based businesses as a way to make quick money with little work. Once associated with envelope-stuffing today's home-based businesses can be as varied as medical transcriptionists realtors and many other types of businesses. Often these businesses are based on services rather than products and some home-based business owners have been forced into entrepreneurship through repeated layoffs and an inability to find positions that suit their abilities or income requirements..."
Abstract This paper outlines why a change management initiative informed by Value Based Management theory is one that stands to benefit a generic retailer interested in improving the fiscal bottom line. The paper briefly discusses what value based management theory is and looks at how the theory allows an organization to isolate value drivers that can determine long term success or failure.
From the Paper "Management theories are always evolving and new ones are emerging, literally, every day. For example, there are management theories for dealing with different people within an organization, theories for dealing with crisis or with change, and theories dealing with acquisition integration and with organizational entrepreneurialism. In spite of this, a case can be made that value-based management (VBM) is as good a theory as exists for balancing an organization's management needs with "bottom-line" effectiveness. With that in mind, the following paper will explore the implementation of a change management initiative (within a hard goods retail organization) that focuses upon revitalizing the organizational warehouse, delivery and gross margin performance of the corporation using value-based management theory. "
An overview of the methods of applying the "activity-based costing system" at Dakota Office Supply, in which actual costs associated with each product are established.
Abstract The paper discusses, in a detailed description, the effectiveness of an activity-based costing system or ABC and the ineffectiveness of the current costing system in use at the Dakota Office Supply (DOS) company . The paper then relates the methodology of implementing ABC at DOS and the procedures involved in its application.

From the Paper "Before performing ABC, a baseline or a starting point is needed for business process improvement and a baseline can be expressed in some form of model. This baseline is critical for DOP because in order to establish this baseline metric the analytics just performed must be done for each individual account. If DOP performs this activity on each customer the strategic management benefits would be substantial because all the excess cost-drivers could be eliminated resulting in much wider operating margins and thus profitability without increasing costs or committing resources to gain this efficiency. Therefore, a baseline is a documentation of the organization's policies, practices, methods, measures, costs and their interrelationships at a particular location at a particular point in time (Maiga & Jacobs, 2003). Through base-lining, activity inputs and outputs across functional lines of business can be identified. ABC is the only improvement methodology that provides output or unit costs. Value added activities are those for which the customers are usually willing to pay in some fashion for the product or service. Non-value added are activities that create waste, result in a delay of some sort, and potentially adds costs to the products or services. Resources are assigned to activities so that the activities can be performed in the first place. Some of Pilgrims' resources are measured in man-hours, machine hours as well as machine maintenance and operational overhead. It is through ABC that an organization can begin to see actual dollar costs against individual activities, and find opportunities to streamline or reduce those costs, or even eliminate the entire activity thus removing the cost altogether. This is the process inherent in ABC that reduces overall expenditures of the company. "
Abstract This paper examines activity based costing (ABC) which is an effective business management tool that will enhance and support a total quality management (TQM) environment. ABC analysis provides the information necessary to make business decisions such as determining if investments in efficiency initiatives, such as just in time (JIT), are warranted. When implementing ABC, management should use proven project management methodology to minimize the risk of failure. ABC is an effective total quality management tool, and supports just-in-time manufacturing methods in several companies as detailed in the paper.
From the Paper "After developing ABC in the 1980?s, Robin Cooper and Robert S. Kaplan have written extensively about its benefits (Shih-Jen & Holinda, p. 46). ABC is defined as a "costing system that identifies the various activities performed in a firm and uses multiple cost drivers"to assign overhead (or indirect costs) to products? (Siegel and Shim 2000, p. 15). ABC seeks to accumulate and allocate factory overhead costs to products (or services) by using focused drivers, such as, quality inspecting, moving, assembly, and matching (Warren, 2002, p. 328). Proponents of ABC cite many examples where cost accuracy is superior to traditional costing methods that use cost bases such as units produced, labor, or machine hours used (Warren, p. 421). "
Abstract The purpose of this study was to investigate the effect of using web based math instruction on Florida assessment tests scores in 8th grade students.
Abstract This paper analyzes and argues that activity based costing is most appropriate for assigning costs to products for all types of organizations.
Abstract This paper looks at some of the of literature on play-based intervention. In particular, it looks at how using play as a means of intervention for children with various problems is a good way to get the child to participate and to do so in a way that is effective and valuable.
From the Paper "This is a critical review of some of the research literature on play-based intervention. Children learn from play and also are drawn to it, so using play as a means of intervention for children with various problems is a good way to get the child to participate and to do so in a way that is effective and valuable. Watson (2004) offers some of the rationale for play therapy, noting that when children play, they often enact some theme that is traumatic or negative for them. Among these are anxious anticipation at the beginning of kindergarten, the reenactment of a recent hospitalization or a frightening movie. "
