Description
The current study sought to reevaluate Cass' Theory of sexual identity formation in terms of lesbian identity development over the past twenty years and how media acts as mediation in lesbian identity development. Ten semi-structured interviews were conducted with only nine useable transcripts analyzed for this thesis. This study is an explanatory investigation into linear stage theory, specifically Cass' theory, as well as the impact of media as a mediator during lesbian identity development. This study had three objectives 1) to gain an understanding of the theory and its components related to lesbian identity development 2) to understand the lesbian identity formation process and 3) to understand the impact and influence if any, media has had on lesbian self-reported identity development. Qualitative methods were used to obtain information and analyze the responses. Results indicate that the participants in this study believed that the coming out process was important. This study's results showed that several of the participants entered each stage of the theory, while others did not. Media had little influence on the identity development, and the participants had mixed reviews of medias portrayal of lesbians. Implications for practice and further research are discussed.

Description
Gays identity is usually cast in generics--statements about an indeterminate number of members in a given category. Sometimes these generic statements often get built up into folk definitions, vague and imprecise ways to talk about objects. Other times generics get co-opted into authentic definitions, definitions that pick out a few traits and assert that real members of the class have these traits and members that do not are simply members by a technicality. I assess how we adopt these generic traits into our language and what are the ramifications of using generic traits as a social identity. I analyze the use of authentic definitions in Queer Theory, particularly Michael Warner's use of authentic traits to define a normative Queer identity. I do not just simply focus on what are the effects, but how these folk or authentic definitions gain currency and, furthermore, how can they be changed. I conclude with an analytic account of what it means to be gay and argue that such an account will undercut many of the problems associated with folk or authentic definitions about being gay.

Description
In response to the need to accurately define group home types, this dissertation focused on providing a clear and distinct definition of the types of group home care, an articulated understanding of the role of group home staff, and an awareness of the impact individuals working in group homes have on the lives of the youth they serve and their influence on the group home environment. Using the qualitative research method Grounded Theory, ten in-depth interviews were conducted with staff who both currently work in group homes, and staff who have left the group home environment. The research question was “What is the influence of group home staff on the ecological environment of the group home?” Ecological framework was the overarching theory, and participants were asked questions regarding their relationships with youth and their impressions of staff impact within the group home. Data analysis influenced by Grounded Theory produced 5 themes: Walking into the unknown, in loco parentis with two sub- themes consanguinity and group home as a home, engagement with two sub- themes of staff/staff engagement and staff/youth engagement, staff impact on youth, with three sub-themes, managing transitions, loss and boundaries, and the final theme of supervisor support. The results indicate that staff do have an impact on the group home, both positive and negative. Also, the group home operates as an intricate ecological environment containing relationships and interactions that influence multiple internal systems. Currently there is a gap in the literature as it relates to clarity within definition of care settings. This dissertation provided a clear definition for the chosen research environment, non-locked, non-therapeutic group home. The results of this dissertation have implications for group home agencies and more broadly child welfare agencies and child welfare social workers in regard to hiring practices, training and supervision. This dissertation provides a springboard for a future research on the ecological group home environment and the people who work there and are responsible for the care of vulnerable children.

Description
A central task for historians and philosophers of science is to characterize and analyze the epistemic practices in a given science. The epistemic practice of a science includes its explanatory goals as well as the methods used to achieve these goals. This dissertation addresses the epistemic practices in gene expression research spanning the mid-twentieth century to the twenty-first century. The critical evaluation of the standard historical narratives of the molecular life sciences clarifies certain philosophical problems with respect to reduction, emergence, and representation, and offers new ways with which to think about the development of scientific research and the nature of scientific change.
The first chapter revisits some of the key experiments that contributed to the development of the repression model of genetic regulation in the lac operon and concludes that the early research on gene expression and genetic regulation depict an iterative and integrative process, which was neither reductionist nor holist. In doing so, it challenges a common application of a conceptual framework in the history of biology and offers an alternative framework. The second chapter argues that the concept of emergence in the history and philosophy of biology is too ambiguous to account for the current research in post-genomic molecular biology and it is often erroneously used to argue against some reductionist theses. The third chapter investigates the use of network representations of gene expression in developmental evolution research and takes up some of the conceptual and methodological problems it has generated. The concluding comments present potential avenues for future research arising from each substantial chapter.
In sum, this dissertation argues that the epistemic practices of gene expression research are an iterative and integrative process, which produces theoretical representations of the complex interactions in gene expression as networks. Moreover, conceptualizing these interactions as networks constrains empirical research strategies by the limited number of ways in which gene expression can be controlled through general rules of network interactions. Making these strategies explicit helps to clarify how they can explain the dynamic and adaptive features of genomes.

Description
This dissertation begins to lay out a small slice of the history of morphological research, and how it has changed, from the late 19th through the close of the 20th century. Investigators using different methods, addressing different questions, holding different assumptions, and coming from different research fields have pursued morphological research programs, i.e. research programs that explore the process of changing form. Subsequently, the way in which investigators have pursued and understood morphology has witnessed significant changes from the 19th century to modern day research. In order to trace this shifting history of morphology, I have selected a particular organ, teeth, and traced a tendril of research on the dentition beginning in the late 19th century and ending at the year 2000. But even focusing on teeth would be impossible; the scope of research on this organ is far too vast. Instead, I narrow this dissertation to investigation of research on a particular problem: explaining mammalian tooth morphology. How researchers have investigated mammalian tooth morphology and what counts as an explanation changed dramatically during this period.
