Global Dynamic E-Marketplaces, And Their Role In The Internet-Based Economy, Mehdi Rafi

Theses

Collaboration capabilities are what will most probably create the gap between winners and losers in business-to-business (B2B) commerce. In this context, the electronic marketplace (EM) comes as a medium for trade and collaboration, and a common entry point where partners can share business processes and adopt a decentralized business model fuelled by market evolution. The thesis illustrates the advantages of collaborative business and presents the information technologies that support it. The purpose of this thesis is to educate both the author and the reader on the technology and infrastructure that supports collaborative business and to posit that among the three …

Economic Analysis Of The Cost Of Inconsistencies In The Implementation Of Isdn Network Layer Standards, Thomas Bennett

Theses

Case studies depicting ISDN network layer interoperability and standards nonconformance were evaluated, and categorized by type. In each case study the root cause of the interoperability problem was identified, and validated with reference to the applicable ISDN standard. Corrective measures were proposed, and where implemented, the results of the correction were documented. Relative costs associated with the interoperability issue were identified, and recommendation's outlining the best method for avoiding these inconsistencies going forward were presented.

Asymmetrical Digital Subscriber Line (Adsl) An In-Depth Study, John Kernan

Theses

Asymmetrical Digital Subscriber Line (ADSL) is one member of a group of broadband access technologies that uses the existing copper-based local loop of the analog PSTN for high-speed digital data transmission. One feature of ADSL is that it permits analog voice POTS transmissions to continue uninterrupted over the same wiring. Specifically, POTS continues to use the 0 to 4 KHz frequency range of the copper wiring, while ADSL uses bandwidth starting at 25 KHz and extending up to approximately 1.1 MHz for data transmission. The term "asymmetrical" refers to the fact that data rates downstream (to the user) and upstream …

The Future Of Data Communications System Design, Kenneth Kellow

Theses

The Information Technology universe and its data communications subset was created largely due to advances in integrated circuit technology. Primarily focused on layer 2 of the OSI model, silicon integration is a technology upon which much of data communications is constructed. Over the past forty years advances in integrated circuit technology have manifested themselves through shrinking structural dimensions and increases in performance. This combination of shrinking structural dimensions also known as circuit density, and performance increases, also known as circuit speed, have led to long term compound productivity increases and a seemingly never ending menu of data communications applications. Recent …

Making Connections: A Study And Application Of Christian Hospitality, Dennis Murphy

The importance of people spending time together and serving side by side is established. Christian Hospitality is defined and added to secular restaurant management wisdom to create a Hospitality Ministry at DCC. This included a weekly brunch that was new in …

Elastic Ladar Modeling For Synthetic Imaging Applications, Robin Burton

Theses

The Digital Imaging and Remote Sensing Image Generation (DIRSIG) model was developed to create synthetic images of remotely sensed scenes (Schott et al. 1999). It is a quantitative model based on first principles that calculates the radiance reaching the sensor from the visible region of the spectrum through to the long-wave. DIRSIG generates a very accurate representation of what a sensor would see by modeling all processes involved in the imaging chain. Currently, DIRSIG only models light from passive sources such as the sun, blackbody radiation due to the temperature of an object, and local incoherent illuminants. Active systems allow …

The Trend Of Academic Achievement And Retention For Immigrant Latino Youth, Pamela Humphrey

Graduate Research Papers

This paper discusses the trend of academic achievement and retention for Latino immigrant youth. Research indicates that the general trend for Latino youth is negative – generally achievement is lower than any other immigrant ethnic group, and the drop out rate is higher than for any other ethnic group. Factors such as language and methods of learning, segregation, poverty, low parental involvement in education, discrimination, and stress due to immigration have been identified as factors contributing to low academic success.

The ways in which schools deal with immigrant students is also discussed. Further research is needed on immigrant Latino families …

Home-School Collaboration : An Effective Intervention For Facilitating Homework Completion?, John D. Warrington

Graduate Research Papers

This paper contains a review of literature on the utilization of home school collaboration as an intervention tool to improve the existing low homework completion rates of many students in our school systems. Due to the fact that homework is one of the most longstanding educational traditions, provides a natural link between the home and the school, and has been implicated as a tool for increasing overall rates of academic achievement, it is important to investigate past and present instruments and modes of assistance that involve both the home and school contexts in a shared partnership. There are a large …

Every Waking Moment: A Young Adolescent Novel Exploring The Effects Of Sleep Deprivation, Jeff Dyer

Graduate Research Papers

Human behavior can be dramatically affected by sleep deprivation (Peretz, 1996). The author gained an extensive understanding of sleep deprivation through a literature review by discovering the answers to questions such as: Does the loss of sleep have an impact on an adolescent's performance and behavior in school? Is this a problem that our nation's educators and parents should be concerned about? If sleep deprivation is in fact a problem for adolescents, how widespread is it?

Information learned during this process was then incorporated into the fictional novel, Every Waking Moment in order to disseminate the data in an entertaining …

Latin American-United States Security Relations And The Power Asymmetry Divide, Matthew R. Slater

Graduate Program in International Studies Theses & Dissertations

Security relations between Latin American and the United States are generally well explained by hegemonic stability theory. Succinctly stated, hegemonic stability theory explains that in systems with a hegemonic power there is a greater likelihood of security cooperation. This is because a hegemon provides public goods, such as a stable currency or security from outside interference, and in turn, the less powerful states acknowledge the leadership of the dominant state. When compared to other regions it is readily apparent that the U.S. and Latin America do not have major security issues on the level of East Asia, the Middle East, …

The Use Of Electronic Technologies In The Cedar Rapids Community Schools' Physical Education Programs, Nicholaus J. Daniel

Graduate Research Papers

How often is electronic technology used in physical education programs? How much electronic technology is available to physical education programs? Does electronic technology and physical education go together? When most people think of electronic technology, they do not think about physical education. Most people tend to think that technology is anything related to a desktop or laptop computer, something you sit down at and work on, not something that involves being physical.

From the researcher's experience in the Cedar Rapids Community School District (CRCSD), there is some pressure for all subject areas to implement and integrate electronic technologies into the …

Establishing Literature Circles In One Middle School Teacher's Classroom, Kristin M. Englert Gehrke

Graduate Research Papers

Literature circles are a popular method of reading instruction in middle school classrooms. Literature circles are when small groups of students choose one book to read and then meet to discuss it. Students are taught how to discuss a book and use response journals. Implementing literature circles into a reading curriculum requires a great deal of planning. A teacher must make decisions about structure, themes, response journals, discussion groups, assessment and final projects.

Literature circles are an evolving teaching method and will not always work the same way each time they are used. I found literature circles to be a …

Improving After-School Programs : A Literature Review, Harriet A. Davis

Graduate Research Papers

The desire and need for after-school programs in the United States is steadily increasing especially for low- to moderate-income children and adolescents. Studies show after-school program participants watch less television and spend more time in academic activities and enrichment lessons (Posner and Vandell 1994). As a result, these programs are extremely beneficial to children who participate in them. After-school programs also provide a safe haven for countless children who need adult supervision at the end of the regular school day.

The following analysis is a compilation of information derived from scholarly journals, books, organizations participating in after-school programs, Internet sources, …

What Parents And Teachers Want To Know About Schools And How Schools Can Advertise This Information Using Technology, Denise H. Krefting

Graduate Research Papers

Finding good teachers is becoming very competitive in our nation as a large number of teachers will be retiring and fewer people are entering the profession. Parents are now shopping for the school that they want their children to attend and then finding the home in that district. The possibility of school vouchers is encouraging this. Schools need to be able to advertise information to potential employees and parents of their school district.

The Waukee School district in Waukee, Iowa works to create an informational CD made available to parents and employees is used as an example of what information …

Maintaining Developmentally Appropriate Practice In An Increasingly Academic Kindergarten, Amy Phillips

Graduate Research Papers

The purpose of this paper was to conduct a review of research to determine whether a developmental or an academic curriculum is most appropriate for kindergarten classrooms. The research outlined the benefits of developmentally appropriate practice, including increased academic performance and better social skills. The research also showed the detriments of developmentally inappropriate practice, including increased stress levels, a stifling of enthusiasm for learning and less advanced academic and social skills.

However, in spite of the research, many early childhood professionals are not fully implementing developmentally appropriate practice. Three main obstacles to full implementation were the following: (a) increased accountability …
