In Pursuit Of Paternal Significance: Fathers' Influence On Their Daughters' And Sons' Sexual Behaviors And Beliefs, Rachel S. Everley

Theses and Dissertations

The United States has the highest teen pregnancy and adolescent STD rates of any industrialized nation. Numerous factors are involved in adolescent sexual decision-making and the social-ecological framework suggests that there are multiple levels of influence on adolescent development, including familial. Utilizing survey data from the Virginia Abstinence Education Initiative (VAEI), this project specifically explores paternal influences on adolescent sexual behavior and beliefs by examining paternal residence in the home, perceived paternal figure sexual beliefs, and father-child relationship factors. Results indicate that paternal figures influence their daughters' and sons' sexual behaviors as well as beliefs. Differences in paternal figure influence …

Characterization Of Microorganisms Of Interest To Homeland Security And Public Health Utilizing Liquid Chromatography/Mass Spectrometry, Robert A. Everley

Theses and Dissertations

Liquid chromatography/quadrupole time of flight mass spectrometry (LC/QTOF MS) utilizing electrospray ionization was employed to monitor protein expression in Escherichia coli and Shigella organisms. Automated charge state deconvolution, spectral subtraction and spectral mirroring were used to reveal subtle differences in the LC/MS data. Reproducible intact protein biomarkers were discovered based on their unique mass, retention time and relative intensity. These markers were implemented to differentiate closely related strain types, (e.g. two distinct isolates of E. coli O157:H7) and to correctly identify unknown pathogens. Notable, was the distinction of multiple serotypes of enterohaemorrhagic E. coli which cannot be distinguished by clinical …

Grace Street Senior Center, Virginia Brockett

Theses and Dissertations

Societal structure has changed through the decades to reflect a contemporary interest in youth culture. The nuclear family, where generations lived under one roof no longer exists, leaving the elderly on the periphery of the family structure. Where once grandparents, parents and children all cohabitated, now the oldest family members are relegated to solitary retirement and aging alone. Studies have shown that "depression in the elderly is more likely to lead to suicide. Elderlywhite men are at greatest risk, with suicide rates in people ages 80 to 84 more than twice that of the general population. The National Institute of …

Sing Together! Choral Singing As A Supplementary Training Method For Actors, Daniel C. Dennis

Theses and Dissertations

Voice and speech training for the actor has traditionally defined itself as distinct from the vocal training of the musical theatre or opera singer. The separation in philosophy and practice by trainers of actors and singers reflects the resultant capabilities and proclivities of our performers. Those performers generally sing or act, and if asked, will sometimes do both, but may damage their voices in the process. This study aims to explore and reveal how actors may develop a greater sense of courage and trust, have easy access to breath, find freedom in their bodies and voices, become better listeners and …

Power Relationships In Information Systems Security Policy Formulation And Implementation, Michael Stephen Lapke

Theses and Dissertations

This thesis argues that organizational power impacts the development and implementation of Information Systems (IS) Security policy. The motivation for this research stems from the continuing concern of ineffective security in organizations, leading to significant monetary losses. IS researchers have contended that ineffective IS Security policy is a precursor to ineffective IS Security (Loch et al. 1992; Whitman et al. 2001; David 2002; Solms and Solms 2004). Beyond this pragmatic aspect, there is a gap in the literature concerning power relationships and IS Security policy. This research intends to bridge the gap. The dissertation is a two phased study whereby …

Self-Produced Child Pornography: The Appropriate Societal Response To Juvenile Self-Sexual Exploitation, Mary Graw Leary

Scholarly Articles

The issues of “sexting” and “self-produced child pornography” (SPCP) have captured the attention of the media, courts, and state legislatures. A debate rages among advocates, policy makers, and reporters about how the law should address this activity. More than sixteen states have considered special legislation to address the problem and litigation has ensued. Lost in the debate are many realities including the complexity of the problem. This behavior implicates aspects of child development, child sexuality, child exploitation, teen dating violence, education, and parenting. While any deliberation about children and how the law should protect children is positive, sensationalism and oversimplification …

Mechanics Of Dump Truck Vibrations In High-Impact Shovel Loading Operations, Nassib Aouad

Doctoral Dissertations

"The deployment of large machinery for low cost, bulk surface mine production operations has resulted in high-impact shovel loading operations (HISLO). In extreme cases, shovels load large dump trucks with 100-ton (or more) passes generating high-impact forces under gravity. HISLO generates high-frequency shockwaves that cause severe truck vibrations exposing operators to whole body vibrations (WBV). This WBV levels may exceed the recommended International Standards Organization (ISO) limits resulting in longterm lower-back disorders and other health problems. There is a need for fundamental and applied research to determine HISLO vibration levels for heavy mining machinery, their comparisons to ISO 2631 limits …

Perspectives Of Change: Municipal Park And Recreation Directors Perceptions Of The Importance Of Specified Organizational Goals 1983–2008, Daniel Archie Wheeler

Dissertations and Theses @ UNI

This study examines specified goals park and recreation directors have previously determined are important for their organizations, and how those goals rank in importance in their present estimations, and how those goals rank in future importance. It compares a similar study of goals from 1983, and reports on changes in levels of importance from 1983 to 2008.

Directors' perceptions of goal importance of 2008 present levels and 2008 future levels were determined to be significantly different in 23 of 26 cases. Goals were grouped in four categories, (a) management/adaptation,/positional, having to do with management tasks, (b) groups served, those targeted …

A Journey Of Advising: Experiences Of Doctoral International Students And Faculty Advisors In The College Of Education At A Midwestern University, Madalina Florentina Tincu

Dissertations and Theses @ UNI

In the last five decades, higher education in the United States has faced a large influx of international students (Institute of International Education, 2004). However, a review of selected literature showed a paucity of research on faculty advising graduate international students. The literature pointed out that not all institutions were prepared to work with the international student population (Adrian-Taylor, Noels, & Tischler, 2007; Khabiri, 1985; Seeger, 1993) and that further investigation was needed in the area of faculty advising related to international students (Adrian-Taylor, et al.; Trice, 2003). Therefore, this study focused on the following research question: How do selected …

Now Have We Gotten It Right?: Exploring The Special Education Referral Process, Janine Sue Wahl

Dissertations and Theses @ UNI

This qualitative inquiry explored the special education referral process as understood and implemented by two first grade teachers in a rural school. Both were interviewed and their classes observed; team meetings about their referrals were attended and recorded. The results of these observations were examined through the beliefs and assumptions about teaching and learning by the two teachers.

Each teacher referred two students into the process during this study, but none of the four students was found eligible for special education services during first grade. Through a cross-case analysis of the teachers and these students, distinct differences and commonalities were …

Disability And Difference: Adolescents' Interpretations Based On Television Viewing, Paula Anne Schmidt

Dissertations and Theses @ UNI

This study was conducted in order to decipher adolescent interpretations of disability that were portrayed on television. Employing qualitative methodology and methods, I conducted focus groups with adolescents during which they viewed television programs containing portrayals of characters with disabilities, or otherwise defining differences. The sixth grade participants freely shared their perspectives of the programs and characters in addition to their thoughts about the nature of difference in general.

Although I originally intended to interpret adolescents' reactions toward characters with disabilities, I found that it was not only characters with disabilities that they viewed in a judgmental manner. As the …

The Reflexivity Of Pain And Privilege: An Autoethnography Of (Mestizo) Identity And Other Mestizo Voices, Ellis Hurd

Dissertations and Theses @ UNI

Approximately 20 million Latinos living in the United States identify as Mestizos. A Mestizo is a person of mixed heritage. Almost half of these Mestizos racially or culturally identify as White, while the other half identify as Hispanic or racially mixed. These racial and cultural identifications have vast effects on educational performance: those identifying themselves as Hispanic or mixed experience lower academic achievement whereas those identifying as White do not. Many communities have experienced an influx of Mestizo-Latinos, but are ill prepared for the educational challenges due to the language and cultural differences Mestizos bring. This researcher himself has experienced …

Control, Counter-Examples, And Reasons-Reluctance, Nicolas Michaud

UNF Graduate Theses and Dissertations

This work considers the soundness of Henry Frankfurt's argument that the principle of alternative possibilities is false and the implications of his argument for holding agents responsible in a causally determined universe. Frankfurt does seem to be pointing clearly to the fact that many of us do continue to hold agents responsible despite a lack of alternative possibilities. What Frankfurt may be lacking is an adequate account of control which is taken up by John Martin Fischer. What Fischer presents us with is the possibility that the reason why we continue to hold Jones responsible is because of the kind …

Substance Use And Barriers To Treatment Across Native Hawaiians/Pacific Islanders And Asian Americans, Lauren Michelle Levine

UNF Graduate Theses and Dissertations

Research shows that Asian Americans have lower rates of substance abuse treatment utilization than Caucasians. However, investigators have recently begun to separate Native Hawaiians/Pacific Islanders (NH/PI) from Asian Americans. Thus, it remains unclear whether disparities in barriers to treatment utilization differ across NH/Pis and Asian Americans. Data (N = 43,093) from the 2001-2002 National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), a large, nationally representative survey was used in this study. A chi-square analysis examined whether disparities in barriers and utilization differed between NH/Pis (n = 300) and Asian Americans (n = 1,334). We found that NH/Pis who thought …

UNF Graduate Theses and Dissertations

This qualitative study analyzed the experience of parenting within Filipino Overseas families as perceived by adult children. The impact of overseas workers is invaluable to the Philippine economy. The current study explored the dimensions of having a parent, mother or father, who is an overseas worker, acknowledging that there are clear challenges of parenting children with the barriers of geographical distance. International long distance telephone interviews were conducted with adult children of Filipino overseas workers. Results from consensual qualitative research analysis (C. E. Hill et al., 2005; C. E. Hill, B. J. Thompson, & E. N. Williams, 1997) indicated two …

The Significance Of Trust For Ethics Critical And Applied: A Critical Account Of Watsuji's Metaethics, Sean Patrick Smith

UNF Graduate Theses and Dissertations

Watsuji Tetsuro's philosophy in the early 20th Century presented a view of ethics that was markedly different from the more common theories of the Western philosophical tradition. He viewed ethics as a natural outgrowth of our essential nature as human beings. By investigating what it means to be human, Watsuji argued, one could develop a stronger understanding of our reasons and methods for being ethical. One of his ideas involved trust's importance and inevitability in our ethical palette. Developed by Watsuji, this connection between trust and our nature as human beings was interesting.

It is my claim that how we …

Tests For Correlation On Bivariate Nonnormal Distributions, Louanne Margaret Beversdorf

UNF Graduate Theses and Dissertations

Many samples in the real world are very small in size and often do not follow a normal distribution. Existing tests for correlation have restrictions on the distribution of data and sample sizes, therefore the current tests cannot be used in some real world situations.

In this thesis, two tests are considered to test hypotheses about the population correlation coefficient. The tests are based on statistics transformed by a saddlepoint approximation and by Fisher's Z-transformation. The tests are conducted on small samples of bivariate nonnormal data and found to perfom well.

Simulations were run in order to compare the type …

Routing Protocol Performance Evaluation For Mobile Ad-Hoc Networks, Pedro A. Lopez-Fernandez

UNF Graduate Theses and Dissertations

Currently, MANETs are a very active area of research, due to their great potential to provide networking capabilities when it is not feasible to have a fixed infrastructure in place, or to provide a complement to the existing infrastructure. Routing in this kind of network is much more challenging than in conventional networks, due to its mobile nature and limited power and hardware resources.

The most practical way to conduct routing studies of MANETs is by means of simulators such as GloMoSim. GloMoSim was utilized in this research to investigate various performance statistics and draw comparisons among different MANET routing …

Based on such findings, the purpose of this study was to further explore the interaction between higher education organizations and enterprise systems during Enterprise Resource Planning (ERP) implementations in order to gain insight into the effects of ERP implementations in higher education. Through the theoretical lens of actor-network theory, the purposes of this comparative case study at …

The Problem Of Religious Learning, Marc O. Degirolami

Scholarly Articles

The problem of religious learning is that religion-including the teaching about religion-must be separated from liberal public education, but that the two cannot be entirely separated if the aims of liberal public education are to be realized. It is a problem that has gone largely unexamined by courts, constitutional scholars, and other legal theorists. Though the U.S. Supreme Court has offered a few terse statements about the permissibility of teaching about religion in its Establishment Clause jurisprudence, and scholars frequently urge policies for or against such controversial subjects as Intelligent Design or graduation prayers, insuffi- cient attention has been paid …

Generalization Of The Hybrid Logistic Model For More Than One Rare Risk Factor, Mamunur Rashid

Mathematics Faculty Publications

Logistic models are commonly used to analyze case-control data. For case-control studies, if there tends be rare disease in the control group with the risk factors, then the estimation procedure using logistic regression model for such factors becomes difficult. To overcome such situation, Chen et. al. (2003) proposed a hybrid logistic model in which they first estimate the problematic risk factor assuming that proportions having disease of such risk factor are treated equal for all permissible strata of the other risk factors, and then the residual of the risk factors are modeled by using logistic regression model. The purpose of …
