Incentive Mechanisms In P2p Media Streaming Systems, Xiao Su, Suchreet Dhaliwal Jan 2010

Incentive Mechanisms In P2p Media Streaming Systems, Xiao Su, Suchreet Dhaliwal

Faculty Publications

This paper highlights the need to curb free-riding in P2P media streaming systems and discusses the mechanisms by which this could be accomplished. Free riding, whereby a peer utilizes network resources, but does not contribute services could have a huge impact on the efficacy of blue streaming systems, leading to scalability issues and service degradation. We discuss why BitTorrent-like tit-for-tat mechanisms cannot be simply tailored and used in streaming. Even though the problem of free riding is more severe in P2P media streaming than in file sharing, the deployed systems still lack incentive schemes. In this paper, we categorize, analyze, …

Copyright And Education: Lessons On African Copyright And Access To Knowledge, Tobias Schonwetter, Jeremy De Beer, Dick Kawooya, Achal Prabhala Jan 2010

Copyright And Education: Lessons On African Copyright And Access To Knowledge, Tobias Schonwetter, Jeremy De Beer, Dick Kawooya, Achal Prabhala

Faculty Publications

The African Copyright and Access to Knowledge (ACA2K) project is a pan-African research network of academics and researchers from law, economics and the information sciences, spanning Egypt, Ghana, Kenya, Morocco, Mozambique, Senegal, South Africa and Uganda. Research conducted by the project was designed to investigate the extent to which copyright is fulfilling its objective of facilitating access to knowledge, and learning materials in particular, in the study countries. The hypotheses tested during the course of research were that: (a) the copyright environments in study countries are not maximising access to learning materials, and (b) the copyright environments in study countries …


It’S Not A Small World After All: Regulating Obesity Globally, Eloisa Rodriguez-Dod Jan 2010

It’S Not A Small World After All: Regulating Obesity Globally, Eloisa Rodriguez-Dod

Faculty Publications

The rate of obesity and overweight among the world population has increased dramatically over the past several years in both adults and children. Childhood obesity is a critical health care concern. There have been well-publicized efforts to regulate children‘s obesity both in the U.S. and abroad through such measures as mandated nutritional school lunch programs.

This article focuses, however, on a less examined area of regulation—the recent worldwide efforts to curb obesity among adults. The regulations discussed in this article include measures proposed or adopted by either administrative agencies or legislative bodies, whether on a local or national level. The …


The Irrepressible Myth Of Klein, Howard M. Wasserman Jan 2010

The Irrepressible Myth Of Klein, Howard M. Wasserman

Faculty Publications

The Reconstruction-era case of United States v. Klein remains the object of a “cult” among commentators and advocates, who see it as a powerful separation of powers precedent. In fact, Klein is a myth—actually two related myths. One is that it is opaque and meaninglessly indeterminate because, given its confusing and disjointed language, its precise doctrinal contours are indecipherable; the other is that Klein is vigorous precedent, likely to be used by a court to invalidate likely federal legislation. Close analysis of Klein, its progeny, and past scholarship uncovers three identifiable core limitations on congressional control over the workings of …


The Precedent Of Pretrial Release At The Icty: A Road Better Left Less Traveled, Megan A. Fairlie Jan 2010

The Precedent Of Pretrial Release At The Icty: A Road Better Left Less Traveled, Megan A. Fairlie

Faculty Publications

In August 2009 the International Criminal Court (ICC) granted the interim release of the Congolese alleged warlord, Jean-Pierre Bemba, who has been accused of war crimes and crimes against humanity in the Central African Republic. This decision left Bemba poised to become the first ICC accused ever to enjoy pre-trial release. Of comparable significance, because the decision draws upon relevant jurisprudence from the International Criminal Tribunal for the former Yugoslavia (ICTY), it highlights the potentially powerful influence of ICTY precedent upon a growing field of international and internationalized criminal justice institutions. The new Bemba release decision is just one in …


Perspectives Of Fitness And Health In College Men And Women, Jennifer J. Waldron, Rodney B. Dieser Jan 2010

Perspectives Of Fitness And Health In College Men And Women, Jennifer J. Waldron, Rodney B. Dieser

Faculty Publications

Because many college students engage in low levels of physical activity, the current study used a qualitative framework to interview 11 college students to examine the meaning physically active college students assign to the practice of fitness and health. Students discussed the importance of healthy eating, but that it was difficult to accomplish at college. Additionally, students intertwined health and fitness with physical appearance and attractiveness. In particular, the media shaped many of their perceptions of health and fitness. Implications of these findings to policy making in higher education, in particular wellness programming, are highlighted.


Planning An Information Commons, Michael J. Whitchurch Jan 2010

Planning An Information Commons, Michael J. Whitchurch

Faculty Publications

Of the steps in implementing an information commons, one of the most important is the planning phase. In order for the planning and implementation to be a success, buy-in and support from library users and administrators is essential. The result of the planning process is a detailed planning document which will influence the success of the commons. The document should include plans for policy changes, space for the commons, staffing issues, and assessments, both before and after implementation. Even with all the planning completed, an evaluation of the viability of and desirability for a commons should determine whether a commons …

The Impact Of Direct And Indirect Experiences On The Development Of Environmental Knowledge, Attitudes, And Behavior, Mat D. Duerden, Peter A. Witt Jan 2010

The Impact Of Direct And Indirect Experiences On The Development Of Environmental Knowledge, Attitudes, And Behavior, Mat D. Duerden, Peter A. Witt

Faculty Publications

This study employed a mixed-methods design to examine the relationship between nature experience type (e.g., direct and indirect) and learning outcomes (e.g., environmental knowledge, attitudes, and behavior) associated with an environmental education, international immersion program for adolescents. Longitudinal data from 108 participant and 49 comparison group members were analyzed to test the study’s hypotheses. Additionally, qualitative data were analyzed using grounded theory methodology to assess participants’ perceptions of these processes. The findings indicate that environmental knowledge increased more than environmental attitudes during the indirect portion of the program (i.e., preparatory program) whereas the direct portion (i.e., international workshop) produced similar …


Social Relationships And Mortality Risk: A Meta-Analytic Review, Julianne Holt-Lunstad Jan 2010

"Life Is Beautiful, Or Is It?" Asked Jakob The Liar, Ilona Klein Jan 2010

"Life Is Beautiful, Or Is It?" Asked Jakob The Liar, Ilona Klein

Faculty Publications

In 1999 the 71st Academy Awards ceremony awarded to the film The Last Days the prize for Best Documentary Feature. Underwritten by Steven Spielberg's Survivors of the Shoah Visual History Foundation, this documentary depicts in a compelling, historically objective fashion what the Nazi regime called the "Endlösung" ["Final Solution"]: the effort to annihilate all of European Jewry. In the film, five Hungarian survivors are interviews with honesty and compassion. Their answers record history as it unwound. Clearly, the intent of the interviews is to assure that historical facts are not falsified, nor taken for granted. Documentaries of this kind can …


The Civil Behavior Of Students: A Survey Of School Professionals, Keely Wilkins, Paul Caldarella, Rachel Crook-Lyon, K. Richard Young Jan 2010

The Civil Behavior Of Students: A Survey Of School Professionals, Keely Wilkins, Paul Caldarella, Rachel Crook-Lyon, K. Richard Young

Faculty Publications

Many authors regard education as a way of increasing civility in society, and some have implemented interventions to improve civility in schools. However, very little empirical data exist on the extent and nature of students' civil behavior. The present study systematically gathered data from 251 school professionals regarding their perceptions of students' civil and uncivil behaviors. Participants perceived students' civil behaviors as occurring more frequently than uncivil behaviors; however, they also indicated a need to increase civil behavior in schools. They provided suggestions on how to accomplish this goal, which include providing direct instruction, modeling civil behavior, incorporating positive behavior …


Parent Involvement In School-Wide Social Skills Instruction: Practice And Perceptions Of A Home Note Program, Michael B. Adams, Sue A. Womack, Ryan H. Shatzer, Paul Caldarella Jan 2010

Parent Involvement In School-Wide Social Skills Instruction: Practice And Perceptions Of A Home Note Program, Michael B. Adams, Sue A. Womack, Ryan H. Shatzer, Paul Caldarella

Faculty Publications

If students are to become proficient at using social skills, parents must be involved in teaching and reinforcing these skills at home. Parent involvement is associated with increased student success, especially when it includes a two-way exchange of information between home and school. As the traditional family has changed, new methods of eliciting parent involvement are needed. This article presents a description and evaluation of a school-wide home note program used to encourage generalization of social skills taught in school to home settings. Teachers (n = 20), parents (n = 107), and students (n = 383) at an elementary school …


The Short-Term Influence Of Free Digital Versions Of Books On Print Sales, John Hilton Iii, David Wiley Jan 2010

The Short-Term Influence Of Free Digital Versions Of Books On Print Sales, John Hilton Iii, David Wiley

Faculty Publications

Increasingly, authors and publishers are freely distributing their books electronically to increase the visibility of their work. A vital question for those with a commercial stake in selling books is, “What happens to book sales if digital versions are given away?” We used BookScan sales data for four categories of books (a total of 41 books) for which we could identify the date when the free digital versions of the books were made available to determine whether the free version affected print sales. We analyzed the data on book sales for the eight weeks before and after the free versions …


Multiscale Modeling Of Cellular Systems In Biology, J. C. Dallon Jan 2010

Multiscale Modeling Of Cellular Systems In Biology, J. C. Dallon

Faculty Publications

Here we review eight different multiscale modeling efforts dealing with cellular systems in biology. The first two models focus on collagen based tissue, one dealing with the biomechanical properties of the tissue and the other focusing on how the dermis is remodeled in scar tissue formation. The next two models deal with first avascular tumor growth and then the role of the vasculature in tumor growth. We then consider two models which use the Immersed Boundary method to model tissue properties and cell-cell adhesion. Finally we conclude with two models with treatments of the Cellular Potts Model. The first models …

Contemporary Contradictions And Challenges Facing Married Fathers And Mothers, Erin K. Holmes, Jennifer Baumgartner, Loren Marks, Rob Palkovitz, Olena Nesteruk

Faculty Publications

Part one of this review chapter provides a brief historical overview of the fathering role. Following this overview, some cultural contradictions and challenges facing fathers, particularly married fathers, are outlined and discussed. Key issues of focus in this section include married fathers balancing economic provision, household work, and involvement in child rearing. Part two of the chapter will overview cultural challenges and contradictions facing mothers, particularly married mothers. The contradictory challenges often inherent in marriage-based mothering include the pressures too simultaneously provide "intensive mothering" and to be extensively involved in a career. In sum, the chapter will illustrate how married …


Romantic Relationships And The Physical And Mental Health Of College Students, Scott R. Braithwaite, Raquel Delevi, Frank Fincham Jan 2010

Romantic Relationships And The Physical And Mental Health Of College Students, Scott R. Braithwaite, Raquel Delevi, Frank Fincham

Faculty Publications

This study tested the hypothesis that, analogous to married individuals, college students in committed romantic relationships experience greater well-being than single college students. In a sample of 1,621 college students, individuals in committed relationships experienced fewer mental health problems and were less likely to be overweight/obese. There were no significant differences between groups in frequency of physical health problems. Examination of 2 models suggested that being in a committed romantic relationship decreases problematic outcomes largely through a reduction in sexual partners, which in turn decreases both risky behaviors and problematic outcomes. These results are discussed in the context of how …


Addressing And Improving Technology Integration Skills For Preservice Teachers Using The Teacher Work Sample, Charles R. Graham, Tonya Tripp, Nancy Wentworth Jan 2010

Addressing And Improving Technology Integration Skills For Preservice Teachers Using The Teacher Work Sample, Charles R. Graham, Tonya Tripp, Nancy Wentworth

Faculty Publications

This study explores the efforts at Brigham Young University to improve preservice candidates’ technology integration using the Teacher Work Sample (TWS) as an assessment tool. Baseline data that was analyzed from 95 TWSs indicated that students were predominantly using technology for productivity and information presentation purposes even though they had been taught to use technology for active student learning. Researchers discovered that decisions made about technology integration were heavily influenced by field instructors and TWS rubrics. An intervention plan was developed to train field instructors and 99 TWSs were analyzed the following year. The TWSs showed noticeable improvements including increases …


Dear Students: Don't Let College Unplug Your Future, Gideon Burton Jan 2010

Dear Students: Don't Let College Unplug Your Future, Gideon Burton

Faculty Publications

I'm about to say something a college professor shouldn't say to his students, but I care about you a lot so I'm prepared to break the code and say what needs to be said: Your college experience is likely to set back your education, your career, and your creative potential. Ironically, this will be done in the name of education. You deserve to know about this! You have what it takes to reclaim, reform, and remix your education. Don't let college unplug your future!

Procter & Gamble’S Pur Purifier Of Water: How Global Corporate Philanthropy Builds Shareholder Value, Lisa Jones Christensen, Carol Seagle

Faculty Publications

“When are you going to change this Children’s Safe Drinking Water program and make money for your company? Surely Procter & Gamble wants you to profit on the water purification technology—you can’t sustain your program as a non-profit!”

Greg Allgood sighed internally at this question, as it seemed to surface frequently despite the continued and rapid growth of the Children’s Safe Drinking Water (CSDW) program at P&G. Allgood (Director of the CSDW program) was not actually frustrated with the query, as he had an easy answer ready. Rather, he wished that people could more easily see how his team’s non-profit …

Couple Relationship Education At Home: Does Skill Training Enhance Relationship Assessment And Feedback?, W. Kim Halford, Keithia Wilson, Bronwyn Watson, Tony Verner, Jeffry Larson, Dean M. Busby, Thomas Holman

Faculty Publications

To evaluate the effective components of couple relationship education, 59 newlywed couples were randomly assigned to one of two couple relationship programs (CRE): (1) RELATE, which involved receiving feedback mono their relationship based on the on-line RELATE assessment; or (2) RELATE + Couple CARE, which was RELATE plus completing the 6 unit Couple CARE relationship skill training program. Relative to RELATE, RELATE + Couple CARE produced more improvement in couple communication, and high relationship satisfaction across the next 12 months in women. Men sustained high and similar relationship satisfaction in either condition. Skill training CRE has additional benefits for couples …

The Creation And Use Of Open Educational Resources In Christian Higher Education, John L. Hilton Iii, David Wiley Dec 2009

The Creation And Use Of Open Educational Resources In Christian Higher Education, John L. Hilton Iii, David Wiley

Faculty Publications

A significant movement in education concerns the use of open educational resources (OERs). By “open” it is generally meant that the resource is freely available to others to reuse in different contexts. These resources could include books, lesson plans, syllabi, slide shows, etc. There are several examples of individuals and institutions providing open educational resources; this openness is also specifically manifest in the field of religious education. I discuss different levels in which OERs can be “open” and the implications of these levels when creating OERs. Common motivations and obstacles to creating OERs are discussed. A particularly significant issue regarding …

A Comparison Of The Wellbeing Of Orphans And Abandoned Children Ages 6–12 In Institutional And Community-Based Care Settings In 5 Less Wealthy Nations, Kathryn Whetten, Jan Ostermann, Rachel A. Whetten, Brian W. Pence, Karen O'Donnell, Lynne C. Messer, Nathan M. Thielman, The Positive Outcomes For Orphans (Pofo) Research Team

Faculty Publications

Background

Leaders are struggling to care for the estimated 143,000,000 orphans and millions more abandoned children worldwide. Global policy makers are advocating that institution-living orphans and abandoned children (OAC) be moved as quickly as possible to a residential family setting and that institutional care be used as a last resort. This analysis tests the hypothesis that institutional care for OAC aged 6–12 is associated with worse health and wellbeing than community residential care using conservative two-tail tests.

Methodology

The Positive Outcomes for Orphans (POFO) study employed two-stage random sampling survey methodology in 6 sites across 5 countries to identify 1,357 …
