The Influence Of Collective Efficacy On Reporting Crime Among College Students, Violet Angelina Colavito
The Influence Of Collective Efficacy On Reporting Crime Among College Students, Violet Angelina Colavito
UNLV Retrospective Theses & Dissertations
Colleges and universities often aim to create a sense of community and a neighborhood feel for students. University campuses are designed in ways that reflect the factors of social cohesion measured by Goudriaan, Wittebrood, and Nieuwbeerta (2006). Crime on college campuses is an important social issue. Data from the NCVS suggest that between 1995 and 2002, college students experienced an estimated 400,000 to 530,000 violent crimes each year; yet only about 35% of violent victimizations against college students were reported to the police (Baum 2005, and Hart 2003). Yet, research exploring the effect of social cohesion and collective efficacy on …

The Pluto Debate: Influence Of Emotions On Belief, Attitude, And Knowledge Change, Suzanne H Broughton
UNLV Retrospective Theses & Dissertations
In line with the "warming trend" (Sinatra, 2005), this study examined the influence of emotions during controversial conceptual change. Issues in science may trigger highly emotional responses (e.g., evolutionary theory). However, it is unclear whether these emotions facilitate or inhibit change; I investigated the nature of emotions engendered when learning about a controversial science topic, Pluto's reclassification, including the valence (positive/negative) and activation (activating/deactivating) of emotions (Pekrun et al., 2002). I also investigated whether belief, attitude, and/or conceptual change could be facilitated through rereading a refutation text and/or rereading during small group discussions. Refutation texts directly state a common misconception, …

The Influence Of Instruction Set And Test Format On The Detection Of Malingering, Teri Jean Forrest
UNLV Retrospective Theses & Dissertations
It is increasingly common for individuals involved in civil litigation to undergo neuropsychological evaluation. This trend increases the possibility that individuals receive trade-secret test information from their attorneys before evaluation in order to maximize their ability to appear injured. However, no known research has examined what effect this knowledge may have on an individual's ability to successfully evade detection as a malingerer. The current investigation examined the performance of archival brain-damaged individuals, normal controls, and individuals in three malingering groups on both previously and newly developed malingering indices for the Wisconsin Card Sorting Test (WCST) and the Halstead Category Test …

Supermarket Tabloid Influence On Mainstream Daily Newspaper Editorial Content, William Glenn Cook
Supermarket Tabloid Influence On Mainstream Daily Newspaper Editorial Content, William Glenn Cook
UNLV Retrospective Theses & Dissertations
Daily newspapers' content is influenced by the tabloid press in two ways. First, the dailies serve as a watchdog by criticizing tabloids' sensational news, covering litigation against tabloids, and allowing the subjects of tabloid reports to rebut or criticize allegations tabloids make against them. Second, the dailies occasionally follow up on or repeat stories first reported by tabloids. This study compared the content of three weekly supermarket tabloids--the National Enquirer, Globe, and Star--against the content of six daily newspapers--the Las Vegas Review-Journal, Las Vegas Sun, Reno Gazette-Journal, Los Angeles Times, New York Times, and USA Today--over a 26-week period.

The Influence Of Blood Flow On Angiogenesis In The 3-Day Chick Embryo, Brett Mark Clarke
The Influence Of Blood Flow On Angiogenesis In The 3-Day Chick Embryo, Brett Mark Clarke
UNLV Retrospective Theses & Dissertations
I hypothesized that experimental elimination of blood flow via ligation of the conotruncus arteriosus would cause a cessation of blood vessel development and even vessel regression. India ink, injected to highlight the vasculature, had no effect on blood flow. Embryos were divided into ligated, sham, and control groups. After ligature placement and 6 hr. reincubation, KCl, added topically induced cardiac arrest. The diameters of the anterior cardinal vein, anterior vitelline vein, vitelline artery, and vitelline vein were not statistically different from sham and control values. Eye diameter increased equally in the presence and absence of blood flow. These results demonstrate …

The Influence Of Perceived Competence, Activity Importance, And Barriers On Adolescent Leisure Participation: Exploring The Potential For Negotiation, Amy Lynn Hyams
UNLV Retrospective Theses & Dissertations
Recent research on leisure constraints proposes that leisure participation is not dependent on the absence of constraints, but rather on the ability to negotiate through them. This alternative view not only identifies the various effects that the negotiation process may have on leisure participation, but recognizes the role of the individual in controlling their leisure behaviors. The purpose of this study was to expand this concept by identifying individual factors that may facilitate or inhibit the negotiation process. Specifically, this study examined the influence of perceived self-competence, activity importance, the absence of perceived barriers, and various demographic factors on adolescent …
