Tides And Air, Kristine R. Synowka Aug 2014

Tides And Air, Kristine R. Synowka

Graduate Theses, Dissertations, and Problem Reports (ETD)

This thesis discusses the intermedia and sculptural artwork for Kristine R. Synowka's exhibition, Tides and Air. Through a wide variety of different media, both traditional and electronic, a hypothetical world split between terrestrial plants and weeds and ocean environments is explored within the space of the gallery. Echoing the movement of the viewer through the gallery space, the imagery switches focus from the familiar backyard plants to an oceanic realm based off the kinds of environments that we mostly know from theory. A possible new mythology relating to animals is subtly hinted at through encounters with artwork portraying animals from …

Flexure Modulus Of Elasticity In Living Branch Wood, Aaron Dwight Carpenter Aug 2014

Flexure Modulus Of Elasticity In Living Branch Wood, Aaron Dwight Carpenter

Graduate Theses, Dissertations, and Problem Reports (ETD)

Ever increasing human populations are creating a desire, and more importantly a demand for urban forests due to a disconnection from nature as more of us become urban dwellers. Future trends predict increases in human populations which will substantially increase the amount of urban lands, especially around metropolitan areas. Urban trees are exposed to different loading regimes than similar trees growing in a traditional forest. They do not have protection from wind that is seen in the middle of a forest stand, and wind loading has been suggested as one of the more important modes of failure .;This research investigated …

Vying For Relevancy In Stockholm: American Environmental Nongovernmental Organizations And The 1972 Un Conference On The Human Environment, Andrew Brown

Graduate Theses, Dissertations, and Problem Reports (ETD)

This thesis examines the roles, ideologies, strategies, and behavior of American environmental nongovernmental organizations (ENGOs) during the 1972 United Nations Conference on the Human Environment. This conference was the first major international conference to address environmental issues. The Stockholm Conference was a meeting for delegates representing national governments to dictate the direction of international environmental regulation. The conference focused on the participation of nations but ENGOs found venues through which to participate in the discussion on the human environment. In this thesis, I argue that even though the official conference limited the participation of ENGOs, these groups functioned as informal …

Psychosocial Predictors Of Breast Awareness Behaviors, Carol Goulet Aug 2014

Psychosocial Predictors Of Breast Awareness Behaviors, Carol Goulet

Graduate Theses, Dissertations, and Problem Reports (ETD)

Whether women should practice breast self-examination (BSE) has been debated for decades. Current guidelines promote understanding how one's breasts normally look and feel through the practice of BSE or informal self-examination practices (referred to as breast awareness). This study investigated how modern women practice breast awareness behaviors, and how personal, theoretical, and psychosocial constructs influence engagement in these behaviors. Data from 626 women without a history of breast cancer were used to investigate associations between psychosocial variables (e.g., anxiety, body dissatisfaction, cancer fatalism; religious beliefs and participation) and breast awareness behaviors (BSE frequency and proficiency, frequency of checking for lumps, …

Developing An Intergroup Anxiety Toward Muslims Scale, Patricia Hopkins Aug 2014

Developing An Intergroup Anxiety Toward Muslims Scale, Patricia Hopkins

Graduate Theses, Dissertations, and Problem Reports (ETD)

Understanding intergroup relations and the anxiety that can result has become increasingly relevant to interactions between Muslim and non-Muslim individuals due to current tensions between Islamic groups and many Western nations (e.g., acts of terrorism in Madrid and London, the U.S. War on Terror). Furthermore, the anticipated increase in migration from the Middle East and North Africa to Western countries will undoubtedly lead to increased contact between Muslim and non-Muslim groups. In order to improve intergroup relations and reduce potential conflict between groups, it is important to understand factors that influence intergroup contact. One such factor is intergroup anxiety, or …

Supervisee Experiences Of Impression Management, The Supervisory Working Alliance, And Counseling Self-Efficacy, Jennifer M. Haist Aug 2014

Supervisee Experiences Of Impression Management, The Supervisory Working Alliance, And Counseling Self-Efficacy, Jennifer M. Haist

Graduate Theses, Dissertations, and Problem Reports (ETD)

Supervision plays a vital role in fostering competent, ethical and effective counseling psychologists. However, studies have shown that supervisees act in ways that counteract the benefits of supervision. Trainees manage supervisor impressions to the detriment of their professional growth; they withhold information that would help supervisors promote learning, clarify misunderstandings, gain insight into supervisee weaknesses and strengths, and provide feedback that would enhance supervisee competence. Supervisee nondisclosure is a particularly prevalent impression management behavior documented in the supervision literature (Hill, Thompson, & Corbett, 1992; Ladany et al., 1996). It and other forms of impression management may be particularly related to …

Faster Evolutionary Multi-Objective Optimization Via Gale, The Geometric Active Learner, Joseph Krall Aug 2014

Faster Evolutionary Multi-Objective Optimization Via Gale, The Geometric Active Learner, Joseph Krall

Graduate Theses, Dissertations, and Problem Reports (ETD)

Goal optimization has long been a topic of great interest in computer science. The literature contains many thousands of papers that discuss methods for the search of optimal solutions to complex problems. In the case of multi-objective optimization, such a search yields iteratively improved approximations to the Pareto frontier, i.e. the set of best solutions contained along a trade-off curve of competing objectives.;To approximate the Pareto frontier, one method that is ubiquitous throughout the field of optimization is stochastic search. Stochastic search engines explore solution spaces by randomly mutating candidate guesses to generate new solutions. This mutation policy is employed …

Inorganic Nanoparticle Nucleation On Polymer Matrices, Adrian John Kosteleski

Graduate Theses, Dissertations, and Problem Reports (ETD)

The introduction of inorganic nanoparticles into organic materials enhances both the mechanical and chemical properties of the material. Metallic nanoparticles, like silver and gold, have been introduced into polymers for use as antimicrobial coatings or dielectric materials, respectively. The challenge in creating these materials currently is the difficulty to homogeneously disperse the particles throughout the polymer matrix. The uneven dispersion of nanoparticles can lead to less than optimal quality and undesired properties. By creating a polymer nanocomposite material with well-controlled size inorganic materials that are evenly dispersed throughout the polymer matrix; we can improve the materials performance and properties. The …

Male-Female Workplace Friendships: Third Party Coworkers' Perceptions Of And Behavior Toward Organizational Peers In Cross-Sex Workplace Friendships, Hailey G. Gillen Aug 2014

Male-Female Workplace Friendships: Third Party Coworkers' Perceptions Of And Behavior Toward Organizational Peers In Cross-Sex Workplace Friendships, Hailey G. Gillen

Graduate Theses, Dissertations, and Problem Reports (ETD)

Workplace relationships range from professional working relationships, to workplace friendships, to romantic relationships at work. Cross-sex (male-female) workplace relationships, including friendships, are especially important for women, as research suggests they may help women to break through the "glass ceiling." Cross-sex workplace friendships are often perceived as romantic (e.g., Elesser & Peplau, 2006; Marks, 1994) and workplace romances are generally perceived negatively (Cowan & Horan, 2014, in press; Gillen & Chory, 2014a; Horan & Chory, 2009, 2011, 2013; Malachowski, et al., 2012). Guided by equity theory (Adams, 1965) and feminist organizational communication theorizing (Buzzanell, 1994), it is therefore hypothesized that organizational …

Visualization And Analysis Tools For Neuronal Tissue, Michael Morehead Aug 2014

Visualization And Analysis Tools For Neuronal Tissue, Michael Morehead

Graduate Theses, Dissertations, and Problem Reports (ETD)

The complex nature of neuronal cellular and circuit structure poses challenges for understanding tissue organization. New techniques in electron microscopy allow for large datasets to be acquired from serial sections of neuronal tissue. These techniques reveal all cells in an unbiased fashion, so their segmentation produces complex structures that must be inspected and analyzed. Although several software packages provide 3D representations of these structures, they are limited to monoscopic projection, and are tailored to the visualization of generic 3D data. On the other hand, stereoscopic display has been shown to improve the immersive experience, with significant gains in understanding spatial …

Watershed - A Transdisciplinary Social Design Process Applied To An Environmental Issue, Forrest Thomas Conroy Aug 2014

Watershed - A Transdisciplinary Social Design Process Applied To An Environmental Issue, Forrest Thomas Conroy

Graduate Theses, Dissertations, and Problem Reports (ETD)

Wicked problems are often vast, complex, and difficult to navigate. Often used in dealing with social design issues, the term "wicked" is intended to connote a problem that is difficult to define and solve rather than its moral implications.1 These problems, like watershed maintenance and pollution mitigation, involve an entwined community of diverse players, intricate systems, and ever-changing terrain. Because of their pluralistic nature, these problems can seem impossible to solve and even impossible to understand. This requires a collective approach and new ways of thinking to create better understanding and solutions. Important changes occur when citizens are knowledgeable, see …

Modeling Errors In Biometric Surveillance And De-Duplication Systems, Brian Matthew Decann Aug 2014

Modeling Errors In Biometric Surveillance And De-Duplication Systems, Brian Matthew Decann

Graduate Theses, Dissertations, and Problem Reports (ETD)

In biometrics-based surveillance and de-duplication applications, the system commonly determines if a given individual has been encountered before. In this dissertation, these applications are viewed as specific instances of a broader class of problems known as Anonymous Identification. Here, the system does not necessarily determine the identity of a person; rather, it merely establishes if the given input biometric data was encountered previously. This dissertation demonstrates that traditional biometric evaluation measures cannot adequately estimate the error rate of an anonymous identification system in general and a de-duplication system in particular. In this regard, the first contribution is the design of …

Examining Physiological Roles Of Adipose Derived Vegf: Consequences In Substrate Availability And Endurance Exercise Capacity In Adipocyte Specific Vegf Deficient Mice, Nicole J. Zachwieja

Graduate Theses, Dissertations, and Problem Reports (ETD)

Reducing vascular endothelial growth factor (VEGF) in adipose tissue alters adipose vascularity and metabolic homeostasis. We hypothesized that this would also affect metabolic responses during exercise-induced stress, and that adipocyte-specific VEGF deficient (adipoVEGF-/-) mice would have impaired endurance capacity. Endurance exercise capacity in adipoVEGF-/- (n=10) and littermate control (n=11) mice was evaluated every 4 weeks between 6 & 24 weeks of age using a submaximal endurance run to exhaustion at 20 m/min, 10-degree incline. Maximal running speed, using incremental increases in speed at 30-second intervals, was tested at 25 weeks of age. Beginning at 6 weeks, and continuing with all …

West Virginia Title I Elementary School Principals' Perceptions Of The Barriers That Interfere With The Delivery Of Educational Services For Foster Children: The Lost At-Risk Children, Janie C. Devaul

Graduate Theses, Dissertations, and Problem Reports (ETD)

Foster children are now considered the most at-risk children in American society. Concern for meeting foster children's educational needs falls with the social services domain, however, it is the school system that is responsible for ensuring that all children receive an appropriate education. The schools have programs and policies in place to help the subgroup of identified at-risk students, but foster children are not part of that subgroup. Schools may be overlooking the needs of the foster child because they do not know them as students with special needs. These special needs are not all academics, but they impact the …

Friendship Quality Of Early Adolescent Girls In Relation To Maternal And Paternal Parenting, Social Anxiety, And Interpersonal Skill, Joanna T. Prout Aug 2014

Friendship Quality Of Early Adolescent Girls In Relation To Maternal And Paternal Parenting, Social Anxiety, And Interpersonal Skill, Joanna T. Prout

Graduate Theses, Dissertations, and Problem Reports (ETD)

Social anxiety has been shown to negatively impact friendship quality across the lifespan, leading to relationships that are less intimate and emotionally supportive. In turn, lower friendship quality and lack of social support have been linked to increased risk for isolation and depression. Early adolescence is a period of transition when the basis of friendship shifts from the ability to be a good play partner to the ability to engage in more complex interpersonal skills such as self-disclosure, provision of emotional support, and assertiveness. The early adolescent period is also a time when levels of social anxiety increase as children …
