Using Negative Feedback To Guide Behavior: Impairments On The Wisconsin Card Sorting Test Relates To Psychosis, Sally Barney

UNLV Theses, Dissertations, Professional Papers, and Capstones

There is increasing controversy regarding the distinction between schizophrenia and bipolar disorder as separate diagnostic categories because these disorders share many features in common. These and other findings suggest that bipolar disorder and schizophrenia may be better conceptualized along a continuum or within more homogeneous subsets of affective, psychotic, and mixed symptomatology.

Dopamine dysregulation has been found in schizophrenia and bipolar disorder, particularly those that experience psychosis during the acute phases of their bipolar illness. Dopamine has been found to play a role in reward and reward learning. Recently, research has found that individuals with schizophrenia experience deficits in reward …

Understanding Urban Sustainability And Quality Of Life: A System Dynamics Approach, Abby Elizabeth Beck

UNLV Theses, Dissertations, Professional Papers, and Capstones

For an urban area to be sustainable, its resources cannot be depleted faster than they can replenish. If an urban area is to provide a high quality of life (QOL), it must offer and maintain an amenity package that satisfies its resident's preferences. Past studies on these topics all have a common thread: sustainability and QOL both pertain to people's relationship to capital. Capital is something that can accumulate and add value to a person or society. If sustainability and QOL are a function of people's relationship with capital, how they use it, deplete it, replenish it and transform it …

Environmental Adaptations At Neolithic Ghwair I As Seen From A Zooarchaeological Perspective, Doss F. Powell

UNLV Theses, Dissertations, Professional Papers, and Capstones

Understanding the Pre-Pottery Neolithic (PPN) environmental adaptations, subsistence patterns, and lifestyles in the southern Levant is pivotal in investigating the consequences of the human transformation from the exploitation of wild resources to the production of food through domestication or, the "Neolithic Revolution". At the most fundamental level, this investigation provides a comprehensive zooarchaeological study of the archaeological faunal assemblage from Ghwair I, a Pre-Pottery Neolithic B (PPNB) community in southern Jordan, in effort to explore local exploitation patterns and refine our understanding of the community's social and economic systems. This type of investigation enhances our current understanding of the spatial …

To Set The World Right: Religious Pluralism And The Progressive Era, Lance Sorenson

UNLV Theses, Dissertations, Professional Papers, and Capstones

The contention of this thesis is that religion played a vital and sometimes overlooked role in the promotion and success of progressive reform. Religious leaders often provided primary leadership for reform. But even when their role was not so direct, they and the institutions they represented helped cloak reform efforts in moral and religious institutional authority in order to garner support for change. The process of spreading reform was directly related to the process of articulating reform in language with which people would be comfortable.

Just as reform efforts inevitably faced traditionalist resistance, they often succeed when cast in traditional …

Retrospective Evaluation Of Oral Health Services For Underserved Children In Clark County, Nevada, Earl Taylor Spader

UNLV Theses, Dissertations, Professional Papers, and Capstones

Disparities in utilization of oral health services have been shown to exist through epidemiological investigations and data analysis. Specifically, disparities exist for utilization of preventative dental care (PDC) and unmet dental need (UDN). The disparities in utilization of PDC and UDN are associated with demographic and insurance variables.

To address the oral health disparities, the University of Nevada, Las Vegas-School of Dental Medicine (UNLV-SDM) was created to improve the health of the citizens of Nevada through innovative programs of oral healthcare services to the community.

Determining An Optimum Cropping Pattern For Egypt, Loujaina M. El Sayed

Theses and Dissertations

Agriculture is considered to be the major economic activity in Egypt despite the government policies that favored other sectors since the second half of the 20^th century. However, Egypt currently faces a food security challenge that stems from the increasing demand for food in light of huge population growth and the inability of the agricultural sector to fulfill the abovementioned increasing demand.

This research focuses on the vertical expansion of the agricultural sector through attempting to determine the optimum cropping mix for Egypt in the year 2017. A fuzzy goal programming (FGP) approach for optimal land allocation is utilized. …

The Motivation Beliefs Inventory: Measuring Motivation Beliefs Using Four Motivation Theories, David C. Facer Jr. Phd

Dissertations

Among organizational consultants, human resources practitioners, and organizational leaders, there has been a resurgence of interest in the subject of employee motivation, in part due to the best-selling book, Drive (Pink, 2009). In this book, the author challenged readers to question their beliefs about what motivates employees; this challenge was based on research that questions the validity of widely used management approaches to employee motivation, particularly those based on reinforcement theory. Answering this challenge was difficult, however, given the lack of instruments designed to measure motivation beliefs at all, much less beliefs from a range of prevalent theories. Using principal …

Preparing Global Leaders: A Theoretical Model For Understanding The Development Of Intercultural Competency, Cynthia Ann Martinez Phd

Dissertations

As globalization increases, organizations are seeking individuals that have developed intercultural competency (ICC) and are prepared to lead for the 21st century. Although there are competing definitions among scholars as to what characteristics (ability, attitude, awareness, behaviors, knowledge, skills, or values) make up ICC (Ang & Van Dyne, 2008; Bennett & Bennett, 2004), a considerable body of research has found that studying abroad is one of the best ways for undergraduate students to develop at least one characteristic of ICC (Chieffo & Griffths, 2004; Deardorff, 2006; Sheridan, 2005). The question remains, however, whether or not study abroad programs can contribute …

Graduate Student Experiences: The Impact Of A Mixed-Cohort Format, Kacy Kilner Hayes Phd

Dissertations

Student cohorts have been regaining popularity among graduate programs over the past few decades because they offer numerous advantages for students and can be molded to fit programmatic needs. The format of these cohorts range from open to closed according to the inclusion or exclusion of additional students during the life of the program. Although a number of graduate level programs employ a mixture of closed- and open-cohort formats, there has been a lack of empirical research examining the benefits or consequences of mixing cohort formats within a single academic program. To address this lack of inquiry, this study utilized …

Toward An Integrated Self: Making Meaning Of The Multiple Identities Of Gay Men In College, Daniel Weston Tillapaugh Phd

Dissertations

Since the mid-twentieth century, a shift in demographics of those attending higher education institutions has resulted in increased attention to underrepresented students and their development, specifically their social identities, including race (Cross, 1991), gender (Gilligan, 1982), and sexual orientation (Cass, 1979; D'Augelli, 1994; Fassinger, 1998). However, many theories have compartmentalized aspects of one's overall identity with little understanding of how one's social identity may influence the development of other identities. In the past decade, the concept of intersectionality (Crenshaw, 1995), which explores the interplay between one's multiple identities and the larger systems of power and privilege within society, has been …

The Paleoecology Of A Morrowan Fossil Bed, Washington Mountain, Fayetteville, Arkansas, Steven Hamlin

Geosciences Undergraduate Honors Theses

This study began with a general survey of Washington Mountain that identified the stratigraphic units outcropping. While doing so, the Wedington Member of the Fayetteville Shale and the Pitkin Limestone were both found on the north face. Both units had been previously mapped as pinching out further south. The discovery of a fossil bed in the upper portion of the Cane Hill on Washington Mountain provided a rare opportunity to study the ecology of early Pennsylvanian fauna. Though the sandstone bed was poorly preserved, 14 separate genera were identified and their ecological niches were compared in an effort to establish …

Do You See Yourself In The Future Or Past? The Moderating Role Of Cultural Orientation In Explaining Temporal Orientation Of Self-Referencing, Seungae Lee

Master's Theses

A cognitive process where audiences relate incoming information to themselves is self-referencing. Advertising practitioners often assume that the self-referencing strategy is one of the most persuasive advertising strategies. Since the self is one of the most well-developed and frequently used constructs in memory, self-referencing advertisements were expected to be more memorable and persuasive (Meyers-Levy & Peracchio, 1996). Further, this self-referencing strategy can result in different consequences of advertisements evaluation depending on which dimension of the self is activated, because the self is a multi-dimensional construct. The current study investigated different types of self-referencing based on temporal orientation of the self. …

Heads Up!

Reflective opposite sex norms are behavior that an individual believes the opposite sex prefers them to do. The current study extends research on this recently introduced construct by examining estimates and influences of reflective norms on drinking in a large high-risk heterosexual sample of male and female college students from two universities. Both gender and Greek-affiliation served as potential statistical moderators of the reflective norms and drinking relationship. All participants (N = 1790; 57% female) answered questions regarding the amount of alcohol they believe members of the opposite sex would like their opposite sex friends, dates, and sexual partners …

So You Are Having A Bad Day: Gender, Goal Orientation And In-Competition Attrition Rate In Competitive Cyclists, Kimberly Sue Fasczewski

Masters Theses and Doctoral Dissertations

Cycling is an endurance sport defined by races that require long intensive efforts. In this atmosphere, athletes who experience a self-proclaimed “bad day” may be inclined to drop out of a competition instead of complete it. Previous research has shown that male athletes demonstrated higher levels of ego orientation and extrinsic motivation while female athletes demonstrated higher levels of goal orientation and intrinsic motivation (White & Duda, 1994). The current study examines the relationship of gender, goal orientation and participation motivation to in-competition drop-out rates among competitive cyclists. Specifically, it was hypothesized that the decision to prematurely drop out of …

Credibility Of First Versus Second Child Sexual Abuse Allegations, Anna Henley

Masters Theses and Doctoral Dissertations

A child witness’s credibility has been defined along two dimensions, honesty and cognitive competence (Ross, Jurden, Lindsay, & Keeney, 2003). In cases where cognitive competence (e.g., memory strength) is more salient to an allegation, then older children are typically viewed as more believable than younger children, whereas in cases where honesty is more salient, then younger children are viewed as more believable than older children. The present research examined whether these perceptions of the child witness held true for repeated allegations of abuse and across types of repeated abuse reported. Two hundred seventy participants were recruited from undergraduate psychology courses. …

An Examination Of Two Methods Of Measuring Inconsistency, Rizwan Ahmed Khan

Masters Theses and Doctoral Dissertations

Previous research has provided evidence for the notion that there are varying levels of inconsistency between individuals when responding to questionnaires with multiple response items. Specifically, there are individual differences in how consistently persons respond to items from the same dimension in a questionnaire (Reddock, Biderman & Nguyen, 2011). Currently, there is not a consensus on how inconsistency should be measured. In the present study inconsistency of responses to the IPIP Big Five questionnaire was measured. Two response formats permitting measurement of inconsistency were compared - a frequency-based format (FB) vs. a traditional Likert scale format. Furthermore, in an effort …

A Comparison Point Of View Video Modeling And Video Self-Modeling For Preschool-Aged Children With Autism Spectrum Disorder, Lindsey Nicole Ogle

Masters Theses and Doctoral Dissertations

Video modeling interventions have been recognized as effective and evidence-based behavioral interventions for individuals with autism spectrum disorders; however, the effectiveness of different types of video modeling is still being explored. The present study examined the effectiveness of point of view video modeling compared to video self-modeling using a novel object retrieval task. A multiple baseline, across participants research design was used to assess four, three to four-year-old children with a primary diagnosis of autism. Although both forms of video modeling were successful in teaching the task to all of the participants, point of view video modeling resulted in faster …

Own And Other Race Face Recognition: The Effects Of Instructions And Other-Race Contact, Emily Susan Pica

Masters Theses and Doctoral Dissertations

The cross-race effect occurs when people are more accurate in identifying members of their own race versus those of other races. An emerging theory of the cross-race effect involves social-cognitive processes such as categorization and individuation (Hugenberg, Miller, & Claypool, 2007). Prior research has examined whether instructions to individuate other-race faces, given at encoding, can improve sensitivity thereby reducing the cross-race effect. Results have been inconsistent. Two experiments sought to examine this social-categorization theory with both White and Black participants. In the first study, individuation instructions did not improve White participants’ sensitivity for other-race faces and decreased sensitivity for same-race …

Testing Work Characteristics As Mediating Factors In The Relationships Among Nurse Leadership, Burnout, And Engagement, Heather Kaye Smith

Masters Theses and Doctoral Dissertations

Nurse staff burnout is a critical element of the quality of worklife for nurses, due to burnout’s positive relationship with turnover/turnover intentions. This study attempted to bridge the gap between two areas of related research: transformational leadership and burnout/engagement, using work characteristics (i.e., areas of worklife: AWL) as mediators of the relationship between leadership and burnout/engagement. A sample (N = 142) of practicing nursing students and full-time working nurses who were recruited from a university, hospital, and social network connections completed a questionnaire that gathered their perceptions of nurse leadership, AWL, and burnout/engagement. Results suggested that transformational leadership is strongly …

Determinants Of Tax Effort: A Cross Country Analysis, Mark Alan Mccoon

Dissertations

This paper analyzes the determinants of tax effort. Tax effort is defined as the aggregate tax level of a country divided by its Gross Domestic Product. A country‘s tax effort is an expression of the tax burden the government imposes on the economy. One of the most fundamental issues confronting a society is the size of the governmental sector. How large should the government be relative to the size of the economy? The nations of the world have crafted many different answers to that question as evidenced by the fact that tax effort and the size of government sectors varies …
