Description
People have known about mass biodiversity loss and the human actions that drive it for decades now, and yet we have largely failed levels to change our behavior to protect the environment. What’s failing to motivate people to change? Some conservation psychologists have partially blamed the negative way we communicate about environmental issues for paralyzing audiences into doing nothing because they feel helpless to change such a big problem. Instead, many psychologists have called for using positive emotions in communication to motivate an audience, but there’s still little research showing whether that’s a more effective approach or not. To study whether positive or negative emotions are really more motivational for inspiring change, I looked at how different emotions were used in the discourse about an emerging conservation technology called de-extinction as a case study. De-extinction claims to be both a tool for fighting biodiversity loss and for inspiring more positive and inspiring narratives in conservation. In this thesis, I examine those claims by exploring five emotions that the discourse around de-extinction elicits: fear, guilt, grief, awe and hope. I examined the motivating power of those emotions and what kind of actions de-extinction discourse motivates or fails to motivate through the way it uses those emotions. I found that de-extinction discourse erases negative emotions and boosts positive ones as many conservation psychologists recommend. However, de-extinction discourse accomplishes this in misleading ways: it minimizes the sense of importance of ongoing extinctions by framing extinction as a reversible phenomenon, and it overstates the ability of technology alone to combat the extinction crisis without requiring societal change. As a result, de-extinction discourse could risk making the public less motivated to take personal action to forward conservation goals. I conclude that positivity or negativity should not be the central concerns for motivating action, but rather efficacy and honesty.

Description
This is a study of scientific realism, and of the extent to which it is undermined by objections that have been raised by advocates of various forms of antirealism. I seek to develop and present a version of scientific realism that improves on past formulations, and then to show that standard antirealist arguments against it do not succeed. In this paper, I will first present my formulation of scientific realism, which conceives of theories as model-based and as fundamentally non-linguistic. I advocate an epistemic position that accords with indirect realism, and I review and assess the threat posed by theses of underdetermination. Next, I review and discuss three important views: the antirealist constructivist view of Thomas Kuhn, the realist view of Norwood Hanson, and the antirealist constructive empiricist view of Bas van Fraassen. I find merits and flaws in all three views. In the course of those discussions, I develop the theme that antirealists' arguments generally depend on assumptions that are open to question, especially from the perspective of the version of realism I advocate. I further argue that these antirealist views are undermined by their own tacit appeals to realism.

Description
The academic literature on science communication widely acknowledges a problem: science communication between experts and lay audiences is important, but it is not done well. General audience popular science books, however, carry a reputation for clear science communication and are understudied in the academic literature. For this doctoral dissertation, I utilize Sam Harris's The Moral Landscape, a general audience science book on the particularly thorny topic of neuroscientific approaches to morality, as a case-study to explore the possibility of using general audience science books as models for science communication more broadly. I conduct a literary analysis of the text that delimits the scope of its project, its intended audience, and the domains of science to be communicated. I also identify seven literary aspects of the text: three positive aspects that facilitate clarity and four negative aspects that interfere with lay public engagement. I conclude that The Moral Landscape relies on an assumed knowledge base and intuitions of its audience that cannot reasonably be expected of lay audiences; therefore, it cannot properly be construed as popular science communication. It nevertheless contains normative lessons for the broader science project, both in literary aspects to be salvaged and literary aspects and concepts to consciously be avoided and combated. I note that The Moral Landscape's failings can also be taken as an indication that typical descriptions of science communication offer under-detailed taxonomies of both audiences for science communication and the varieties of science communication aimed at those audiences. Future directions of study include rethinking appropriate target audiences for science literacy projects and developing a more discriminating taxonomy of both science communication and lay publics.

Description
Once perceived as an unimportant occurrence in living organisms, cell degeneration was reconfigured as an important biological phenomenon in development, aging, health, and diseases in the twentieth century. This dissertation tells a twentieth-century history of scientific investigations on cell degeneration, including cell death and aging. By describing four central developments in cell degeneration research with the four major chapters, I trace the emergence of the degenerating cell as a scientific object, describe the generations of a variety of concepts, interpretations and usages associated with cell death and aging, and analyze the transforming influences of the rising cell degeneration research. Particularly, the four chapters show how the changing scientific practices about cellular life in embryology, cell culture, aging research, and molecular biology of Caenorhabditis elegans shaped the interpretations about cell degeneration in the twentieth-century as life-shaping, limit-setting, complex, yet regulated. These events created and consolidated important concepts in life sciences such as programmed cell death, the Hayflick limit, apoptosis, and death genes. These cases also transformed the material and epistemic practices about the end of cellular life subsequently and led to the formations of new research communities. The four cases together show the ways cell degeneration became a shared subject between molecular cell biology, developmental biology, gerontology, oncology, and pathology of degenerative diseases. These practices and perspectives created a special kind of interconnectivity between different fields and led to a level of interdisciplinarity within cell degeneration research by the early 1990s.

Description
The present essay addresses the epistemic difficulties involved in achieving consensus with respect to the Hayek-Keynes debate. In particular, it is argued that the debate cannot be settled on the basis of the observable evidence; or, more precisely, that the empirical implications of the theories of Hayek and Keynes are such that, regardless of what is observed, both of the theories can be interpreted as true, or at least, not falsified. Regardless of the evidence, both Hayek and Keynes can be interpreted as right. The underdetermination of theories by evidence is an old and ubiquitous problem in science. The present essay makes explicit the respects in which the empirical evidence underdetermines the choice between the theories of Hayek and Keynes. In particular, it is argued both that there are convenient responses one can offer that protect each theory from what appears to be threatening evidence (i.e., that the choice between the two theories is underdetermined in the holist sense) and that, for particular kinds of evidence, the two theories are empirically equivalent (i.e., with respect to certain kinds of evidence, the choice between the two theories is underdetermined in the contrastive sense).

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
This dissertation analyzes the way in which leaders of certain Taiwanese Buddhist organizations associated with a strand of Buddhist modernism called "humanistic Buddhism" use discourse and rhetoric to make environmentalism meaningful to their members. It begins with an assessment of the field of religion and ecology, situating it in the context of secular environmental ethics. It identifies rhetoric and discourse as important but under acknowledged elements in literature on environmental ethics, both religious and secular, and relates this lack of attention to rhetoric to the presence of a problematic gap between environmental ethics theory and environmentalist practice. This dissertation develops a methodology of rhetorical analysis that seeks to assess how rhetoric contributes to alleviating this gap in religious environmentalism. In particular, this dissertation analyzes the development of environmentalism as a major element of humanistic Buddhist groups in Taiwan and seeks to show that a rhetorical analysis helps demonstrate how these organizations have sought to make environmentalism a meaningful subject of contemporary Buddhist religiosity. This dissertation will present an extended analysis of the concept of "spiritual environmentalism," a term developed and promoted by the late Ven. Shengyan (1930-2009), founder of the Taiwanese Buddhist organization Dharma Drum Mountain. Furthermore, this dissertation suggests that the rhetorical methodology proposed herein offers offers a direction for scholars to more effectively engage with religion and ecology in ways that address both descriptive/analytic approaches and constructive engagements with various forms of religious environmentalism.

Description
Professional environmental scientists are increasingly under pressure to inform and even shape policy. Scientists engage policy effectively when they act within the bounds of objectivity, credibility, and authority, yet significant portions of the scientific community condemn such acts as advocacy. They argue that it is nonobjective, that it risks damaging the credibility of science, and that it is an abuse of authority. This means objectivity, credibility, and authority deserve direct attention before the policy advocacy quagmire can be reasonably understood. I investigate the meaning of objectivity in science and that necessarily brings the roles of values in science into question. This thesis is a sociological study of the roles environmental values play in the decisions of environmental scientists working in the institution of academia. I argue that the gridlocked nature of the environmental policy advocacy debates can be traced to what seems to be a deep tension and perhaps confusion among these scientists. I provide empirical evidence of this tension and confusion through the use of in depth semi-structured interviews among a sampling of academic environmental scientists (AES). I show that there is a struggle for these AES to reconcile their support for environmentalist values and goals with their commitment to scientific objectivity and their concerns about being credible scientists in the academy. Additionally, I supplemented my data collection with environmental sociology and history, plus philosophy and sociology of science literatures. With this, I developed a system for understanding values in science (of which environmental values are a subset) with respect to the limits of my sample and study. This examination of respondent behavior provides support that it is possible for AES to act on their environmental values without compromising their objectivity, credibility, and authority. These scientists were not likely to practice this in conversations with colleagues and policy-makers, but were likely to behave this way with students. The legitimate extension of this behavior is a viable route for continuing to integrate the human and social dimensions of environmental science into its practice, its training, and its relationship with policy.

Description
In this paper, I analyze representations of nature in popular film, using the feminist / deconstructionist concept of a dualism to structure my critique. Using Val Plumwood’s analysis of the logical structure of dualism and the 5 ‘features of a dualism’ that she identifies, I critique 5 popular movies – Star Wars, Lord of the Rings, Brave, Grizzly Man, and Planet Earth – by locating within each of them one of the 5 features and explaining how the movie functions to reinforce the Nature/Culture dualism . By showing how the Nature/Culture dualism shapes and is shaped by popular cinema, I show how “Nature” is a social construct, created as part of this very dualism, and reified through popular culture. I conclude with the introduction of a number of ‘subversive’ pieces of visual art that undermine and actively deconstruct the Nature/Culture dualism and show to the viewer a more honest presentation of the non-human world.

Description
Breast cancer affects hundreds of thousands of women a year in the United States, and kills tens of thousands. African-American women experience a lower incidence of breast cancer, yet they die at twice the rate of Caucasian women. This disparity demonstrates the ineffectiveness of mammography at decreasing mortality in women at higher risk of late stage diagnosis. In this paper I argue that the continued support of the predominating idea that the benefits of mammograms strictly outweigh their negative effects may be a factor in the continued racial disparity in breast cancer mortality between African-American and Caucasian women. In addition, I will argue that mammograms are less effective for African American women because they are predisposed to later stage diagnosis and the accompanying poorer mortality prognosis due to higher-risk environments caused by varied socio-political status. My claims are supported by studies of incidence rates, survivorship versus mortality rates, screening usage rates, late stage and early stage diagnosis rate, tumor type, and the effects of socioeconomic status on stage of diagnosis. In particular, mortality rates have not decreased parallel with increased mammogram usage, especially in African-American women. Although early stage diagnosis has drastically increased, late stage-diagnosis remains unchanged and higher in African-American women. Tumor types vary by race, and African American women tend to have tumors that are highly prolific and more likely to be metastatic. Socioeconomic factors are more of a marker for breast cancer disparities than race, however race and socio-political structures that embody racism are often intersected.
