The Effects Of Immediate And Delayed Feedback On Secondary Distance Learners, Duane C. Lemley, Richard Sudweeks, Scott L. Howell, R. Dwight Laws, Octavia Sawyer

Faculty Publications

This study explores the effects of immediate and delayed feedback for 2 noncohort groups of high school students enrolled in distance learning courses at Brigham Young University. One group received immediate feedback while the second group received delayed feedback. Those students receiving immediate feedback performed significantly better on final exams, but those who received delayed feedback completed courses in significantly less time. The findings promise to inform best practices for providing feedback to secondary students in a distance learning setting and also give cause for further research.

The Best Defense: Why Elected Courts Should Lead Recusal Reform, Deborah Goldberg, James Sample, David E. Pozen

Hofstra Law Faculty Scholarship

In recent years, we have seen an escalation of attacks on the independence of the judiciary. Government officials and citizens who have been upset by the substance of judicial decisions are increasingly seeking to rein in the courts by limiting their jurisdiction over controversial matters, soliciting pre-election commitments from judicial candidates, and drafting ballot initiatives with sanctions for judges who make unpopular rulings. Many of these efforts betray ignorance at best, or defiance at worst, of traditional principles of separation of powers and constitutional protections against tyranny of the majority.

The attacks are fueled in part by the growing influence …

Kramer Vs. Kramer Revisited: A Comment On The Miller Commission Report And The Obligation Of Divorce Lawyers For Parents To Discuss Alternative Dispute Resolution With Their Clients, Andrew Schepard

Hofstra Law Faculty Scholarship

The 2006 Report of New York State's Matrimonial Commission to Chief Judge Kaye (commonly know as the Miller Commission Report) recommended that New York begin to incorporate alternative dispute resolution into the State's fragmented and adversarial divorce system. This Comment argues that it should have more strongly recommended that divorce lawyers be mandated to discuss alternative dispute resolution, particularly mediation, with parent-clients before filing suit.

The Comment begins by describing the advice given to a parent client in the movie Kramer vs. Kramer and argues that that advice constitutes zealous advocacy as famously described by Henry Lord Brougham in Queen …

Sexual Minority Youth In The Research Literature : What Kind Of Coverage Is The Field Of School Psychology Providing?, Jill Hayes White

Dissertations and Theses @ UNI

The amount of coverage sexual minority youth have received in the research literature over the past 15 years was examined. A content analysis of all research articles published in Psychology in the Schools and The Journal of School Psychology from 1990 to 2005 was conducted. Comparisons were made between the topic areas receiving the most coverage in 1990 versus 2005. Results revealed that issues related to lesbian, gay, bisexual and transgender youth were discussed in only 0.4% of the articles. Topic areas receiving the most coverage included assessment, intervention, ethical and professional issues as well as race and diversity issues, …

Philosophy Of New Jazz: Reconstructing Adorno, Dustin Bradley Garlitz

USF Tampa Graduate Theses and Dissertations

Theodor W. Adorno, the towering twentieth century German intellectual figure and distinctive musical thinker, was legendary for being over-critical of jazz music. Through a consideration at his admiration for avant-garde chamber and symphonic music, I plan to develop a position that, surprisingly, points towards a theory of unacknowledged acceptance of jazz. The style of jazz that will be the newly constructed musical idiom of admiration for Adorno will be of the heterodox variety. My method of reconstruction will be to interrogate the inconsistencies in Adorno's critical musical writings, and negate such negations with factual evidence of affirmation found in the …

Do You See What I Mean? Measuring Consensus Of Agreement And Understanding Of A National Weather Service Informational Graphic, Lorna M. Geggis

USF Tampa Graduate Theses and Dissertations

Media use of hurricane graphics to apprise populations vulnerable to severe weather provides a persuasive demonstration of the importance and complexity of visual communication. Surprisingly little research, however, has explored how audiences interpret weather graphics. This study examined whether the general public and the National Weather Service share a common understanding of selected weather related terms and meaning of a NWS informational graphic. Using a coorientation model, general public responses to a questionnaire were compared to definitions prescribed by the NWS. Additionally, the public were asked questions to measure trust of the NWS as a credible and reliable source of …

The Appeal Of The Underdog: Definition Of The Construct And Implications For The Self, Nadav Goldschmied

USF Tampa Graduate Theses and Dissertations

From politics to sports to business, people are quick to categorize those at a considerable competitive disadvantage as "underdogs." Moreover, there is ample support that most unattached observers do not hesitate to align themselves with underdogs, a phenomenon termed "the underdog effect." While most dictionary definitions state that underdogs are "especially expected to lose," the present investigation argues that people often attribute optimistic qualities to underdogs and the exceeding of expectations. A series of studies was conducted to examine the lay-person definition of what an underdog means, as well as what motivations may play a role in the underdog effect. …

A Paradox Of Diversity: Billions Invested, But Women Still Leave, Rebekah S. Heppner

USF Tampa Graduate Theses and Dissertations

In 2005, women made up 46.4 percent of the United States labor force but only 1.6 percent of Fortune 500 CEOs (Catalyst 2006). Although gains have been made since the passage of the Civil Rights Act in 1964, there is clearly something stopping women from equal representation at the top. Since the late 1980s, businesses have spent billions of dollars on initiatives designed to assist them in dealing with the anticipated increase in the "diversity" of their workplaces (Lubove 1997; Stodghill II 1996; Johnston and Packer 1987). Is there potential for diversity initiatives to help women conquer the "glass ceiling?" …

Mathematical Techniques For The Estimation Of The Diffusion Coefficient And Elimination Constant Of Agents In Subcutaneous Tissue, Lawrence T. Hersh

USF Tampa Graduate Theses and Dissertations

The purpose of this work was to develop methods to estimate the diffusion coefficient and elimination constant for dexamethasone in subcutaneous tissue. Solutions to the diffusion equation were found for different conditions relevant to implantation and injection. These solutions were then used as models for measured autoradiography data where the unknown model parameters were the diffusion coefficient and the elimination constant. The diffusion coefficient and elimination constant were then estimated by curve fitting the measured data to these models. Having these estimates would be of practical importance since inflammation surrounding implantable glucose sensors may be controlled through local release of …

The Effects Of Organizational Structure On Faculty Job Performance, Job Satisfaction, And Counterproductive Work Behavior, Stacey R. Kessler

USF Tampa Graduate Theses and Dissertations

Organizational researchers focus on group level variables such as organizational climate and organizational structure. The purpose of the current meso-level study is to examine the effects of the structure of an academic department on faculty members' job performance, job satisfaction, and prevalence of counterproductive work behavior (CWB), or harmful behaviors while at work. The sample consisted of 1135 full time faculty members working in 229 academic departments throughout the United States and Canada. Results of the study suggested that faculty members working in a more organically structured department report higher levels of job satisfaction. Additionally, productive faculty members working in …

The Gothic As Counter-Discourse: Mark Twain, Charles Chesnutt And Toni Morrison, Hyejin, Kim

USF Tampa Graduate Theses and Dissertations

Revisiting the American Gothic via Julia Kristeva's theory of "the abject" demonstrates how Gothic strategies expose the historical contradictions of race in works by Mark Twain, Charles W. Chesnutt, and Toni Morrison. As theorized by Kristeva in Powers of Horror, the archaic process in which the subject attempts to constitute itself as homogeneous by casting off or "abjecting" all that cannot be assimilated to the self-same necessarily opens the way to repeated returns of the abject(ed) and the "horror" it provokes. Because the Gothic enacts the return of the abject, it was itself abjected from the literary canon until recently. …

Comparative Effects Of The Toxic Dinoflagellate, Karenia Brevis, On Bivalve Molluscs From Florida, James R. Leverone

USF Tampa Graduate Theses and Dissertations

The effects of the toxic dinoflagellate, karenia brevis (Wilson clone), on larval survival and development of the northern quahog (=hard clam, Mercenaria mercenaria), eastern oyster (Crassostrea virginica) and bay scallop (Argopecten irradians) were studied in the laboratory. The effects of K. brevis on feeding activities of juveniles from these species plus the green mussel (Perna viridis) were also examined. Finally, adult bay scallops were exposed to K. brevis for two weeks to investigate possible cytotoxic effects. Survival of 3-day-old larvae was generally > 85% for all shellfish species at Karenia brevis densities of 100 cells . ml-1 or less, and not …

The Role Of Alternative Press In Mobilization For Political Change In Kenya 1982-1992 Society Magazine As A Case Study, Pius M. Nyamora

USF Tampa Graduate Theses and Dissertations

The purpose of this study was to investigate the role of alternative press in mobilizing Kenyans to regain a multi-party political system after 29 years of one-party rule that had turned into authoritarianism. The study focused on Society magazine, and touched on two other magazines, Finance and Nairobi Law Monthly. Unlike Society, these magazines were not intended to cover politics, although they changed their role later. Finance and Nairobi Law Monthly were examined through secondary sources and the author's interactions with the publishers. Whereas Society was a weekly founded and run by journalists, Finance and Nairobi Law Monthly were monthlies …

Real Challenges, Virtual Challengers: The Democracy For America Movement, Noah Porter

USF Tampa Graduate Theses and Dissertations

The project examines the effects of Internet use by the social movement organization (SMO) Dean for America/Democracy for America (DFA). This study describes the relationship between Internet usage and SMO beliefs, organization, causes, reasons for joining, strategies, reactions, and effects. Dean for America started out with few resources or supporters, and was seen as an unlikely contender for the 2004 presidential campaign. From its humble beginnings, it skyrocketed from being virtually unknown to frontrunner status in the span of a year. After Howard Dean withdrew from the race in February 2004, Dean for America transformed itself into Democracy for America, …

Credibility Perceptions Of Television And Online News, Charmy G. Sabigan

USF Tampa Graduate Theses and Dissertations

Three major factors influence audience's credibility perception of mediated news on television and on the internet. This study found that reporters' credibility, media credibility, and news credibility had direct influence to the credibility of news presented on both media. Reporters' credibility on both media could be measured by their expertise, intelligence, education, trustworthiness, and authoritativeness. Television and the internet were evaluated differently. Television was measured by its comprehensiveness, concern for the interest of the public, and fairness. The internet was assessed on its trustworthiness, consideration of public interest, and objectivity. News credibility for both media, however, could be evaluated using …

Generation And Characterization Of An Attenuated Mutant In A Response-Regulator Gene Of Francisella Tularensis Live Vaccine Strain (Lvs), Wendy L. Sammons

USF Tampa Graduate Theses and Dissertations

Francisella tularensis is a zoonotic bacterium that must exist in diverse environments ranging from arthropod vectors to mammalian hosts. To better understand how genes are regulated in these different environments, a transcriptional response- regulator gene (genome locus FTL0552) was deleted in F. tularensis live vaccine strain (LVS). The FTL0552 deletion mutant exhibited slightly reduced rates of extracellular growth but was unable to replicate or survive in mouse macrophages and was avirulent in the mouse model using either BALB/c or C57BL/6 mice. Mice infected with the FTL0552 mutant produced reduced levels of inflammatory cytokines, exhibited reduced histopathology and cleared the bacteria …

Anticonsultative Trends In Nonprofit Governance, Norman I. Silber

Hofstra Law Faculty Scholarship

The cultural and political demand for nonprofit financial accountability has grown rapidly in recent decades. At the same time, donations and gifts continue, apparently, to decline as a proportion of overall revenue received. To remain viable in this environment, many nonprofit groups are changing their operating models and organizational structures, the better to attract contracts, grants, and fee-for-service revenue. An under-appreciated consequence of the convergence of these accountability and viability challenges is an anti-consultative or anti-collaborative imperative. With increasing frequency, scholars, attorneys, and consultants are advising nonprofit groups that seek to comply with nonprofit laws and to enhance their financial …

Should Corporations Have First Amendment Rights?, Daniel J.H. Greenwood, Kent Greenfield, Erik S. Jaffe

Hofstra Law Faculty Scholarship

Corporations are the wrong sort of thing to have speech rights. In contrast to the Supreme Court's free speech law, which focuses on the rights of listeners rather than the rights of speakers, I argue that the speaker makes a difference. For-profit business corporations best fulfill their role in our market democracy if they are controlled by a legally structured market, not when they expand their purview to include regulating their regulators.

In Search Of Validity: A New Model For The Content And Procedural Treatment Of Trademark Infringement Surveys, Irina D. Manta

Hofstra Law Faculty Scholarship

A world devoid of trademark protection is difficult to imagine and has in fact barely existed.' Even marks developed thousands of years ago served the purposes of those present today: trademarks allowed for advertising, answered questions of ownership, and provided quality seals. In modern language, it is said that trademarks "seek to economize on information costs by providing a compact, memorable, and unambiguous identifier of a product or service." Trademarks thus both serve to attract consumers to a good in the first place and then encourage consumers to return to the product. If an individual liked a particular product, a …

Devil In A White Coat: The Temptation Of Forensic Evidence In The Age Of Csi, J. Herbie Difonzo, Ruth C. Stern

Hofstra Law Faculty Scholarship

On October 13, 2006, a couple and their two small children were found shot to death on a desolate stretch of Florida highway. Police found tracks along the roadway belonging to a van or sport utility vehicle. Concluding that the killer and the victims may have been traveling together, police also noted that the victims may have been lying down or kneeling when shot. The mother's defensive posture indicated that she had tried to shield the children from the bullets with her body. No footprints were found in the vicinity and the only physical evidence on the scene consisted of …

Learning From Iraq: Counterinsurgency In American Strategy, Steven Metz Dr.

Books, Monographs & Collaborative Studies

While the involvement of the United States in counterinsurgency has a long history, it had faded in importance in the years following the end of the Cold War. When American forces first confronted it in Iraq, they were not fully prepared. Since then, the U.S. military and other government agencies have expended much effort to refine their counterinsurgency capabilities. But have they done enough?

Hypoxia-Regulated Carbonic Anhydrase Ix Expression Is Associated With Poor Survival In Patients With Invasive Breast Cancer, Sa Hussain, R Ganesan, G Reynolds, L Gross, Et Al

Peninsula Medical School

Tumour hypoxia is a microenvironmental factor related to poor response to radiation, chemotherapy, genetic instability, selection for resistance to apoptosis, and increased risk of invasion and metastasis. Hypoxia-regulated carbonic anhydrase IX (CA IX) has been studied in various tumour sites and its expression has been correlated with the clinical outcome. The purpose of this study was to investigate the correlation of CA IX expression with outcome in patients with invasive breast cancer. We conducted a retrospective study examining the effects of carbonic anhydrase IX (CA IX) on survival in patients with breast cancer. To facilitate the screening of multiple tissue …

A Divided America? Examining The Polarization Of The Electorate From 1974 To 2004, Liz Chandler '07

Res Publica - Journal of Undergraduate Research

To what extent are Americans divided in terms of their liberal and conservative preferences? Have their opinions become more polarized over time? Much of the recent literature on voter polarization suggests that there are far fewer moderate voters in the United States today compared to in the recent past, and that the country is in the midst of a massive “culture war” between liberals and conservatives. By examining public opinion polls taken from the 1970s until today, this analysis finds that in contrast to the suggestions that these authors make in regards to voter polarization, American voters have not steadily …

Bipolar Disorder, Disclosure, And Their Effects On Employment Opportunities, Melissa B. Finch '07

Honors Projects

People with psychological disorders often experience stigma and discrimination, which can impact their ability to gain and maintain employment (Goldberg, Killeen, & O'Day, 2005). The purpose of this study was to examine the impact of disclosure of a severe mental disorder (bipolar disorder) on employers' reactions. In addition, the study assessed the impact of diversity education on employers hiring recommendations for persons with severe mental disabilities. Participants listened to an interview of a student job applicant in one of three conditions (no disclosure, implicit disclosure, or explicit disclosure.) They rated the applicant on personal characteristics and likeability, as well as …

Reducing Hiv Stigma: A Common Group Identity Perspective, Heather Deutsch '07

Honors Projects

The HIV/AIDS epidemic affects many individuals worldwide. Coupled with this epidemic is stigma levied against infected individuals. HIV stigma involves feelings of repulsion, discomfort, blaming, and sanctions. I attempted to combat HIV stigma by targeting emotional, motivational, and behavioral underpinnings in an intervention video. In this video, I manipulated: 1) whether the intervention speaker shared a group membership (IWU affiliation) with the audience and 2) the speaker's HIV status. I hypothesized that, when the speaker was affiliated with IWU and was HIV-positive, stigma would be reduced. Seventy-one lWU students watched the intervention video, and then I assessed participants' HIV-related implicit …

Quantum Dot Energy Relaxation Mediated By Plasmon Emission In Doped Covalent Semiconductor Heterostructures, A. V. Fedorov, Anna Baranov, I. D. Rukhlenko, T. S. Perova, Kevin Berwick

Articles

The interaction between interface plasmons within a doped substrate and quantum dot electrons or holes has been theoretically studied in double heterostructures based on covalent semiconductors. The interface plasmon modes, the corresponding dispersion relationship, and the intraband carrier relaxation rate in quantum dots are reported. We find the critical points in the interface plasmon density of states for multilayered structures results in enhanced quantum dot intraband carrier relaxation when compared to that for a single heterostructure. A detailed discussion is made of the relaxation rate and the spectral position dependencies on the quantum dot layer thickness as well as on …

Diffusion And Fractional Diffusion Based Models For Multiple Light Scattering And Image Analysis, Jonathan Blackledge

Articles

This paper considers a fractional light diffusion model as an approach to characterizing the case when intermediate scattering processes are present, i.e. the scattering regime is neither strong nor weak. In order to introduce the basis for this approach, we revisit the elements of formal scattering theory and the classical diffusion problem in terms of solutions to the inhomogeneous wave and diffusion equations respectively. We then address the significance of these equations in terms of a random walk model for multiple scattering. This leads to the proposition of a fractional diffusion equation for modelling intermediate strength scattering that is based …
