Description
Numerous studies have examined the attachments individuals have to the places they visit, and that those attachments are formed through experiencing a place in person. This study is unique in that it examines pre-trip place attachment formation via the use of mobile technology and social media. It proposes that media experienced through the use of a participant's smartphone can foster the development of positive emotions, which in turn, facilitates greater mental imagery processing that ultimately influences pre-trip place attachment formation. An experimental design was constructed to examine how text and video on a destination's Facebook page influences an individual's emotions, mental imagery, and subsequently attachment to that destination. Specifically, a 2 (narrative text vs. descriptive text) x 2 (short, fast-paced video vs. long, slow-paced video) between-subjects design was used. A total of 343 usable participant responses were included in the analysis. The data was then analyzed through a two-step process using structural equation modeling. Results revealed no significant influence of textual or video media on emotions although the choice in text has a greater influence on emotions than choice in video. Additionally, emotions had a significant impact on mental imagery. Finally, mental imagery processing had a significant impact on only the social bonding dimension of place attachment. In conclusion, while media had no significant impact on emotions, the effect of previous traveler's retelling of personal accounts on the emotions of potential travelers researching a destination should be examined more closely. Further, the study participants had no prior experience with the destination, yet emotions influenced mental imagery, which also influenced social bonding. Thus further research should be conducted to better understand how potential traveler's image of a destination can be affected by the stories or others.

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
One activity for which philosophers are perhaps best known is having disputes with one another. Some non-philosophers, and increasingly many philosophers, believe that a number of these disputes are silly or misguided in some way. Call such silly or misguided disputes defective disputes. When is a dispute defective? What kinds of defective disputes are there? How are these different kinds of defective disputes different from one another? What does it mean to call a dispute 'merely verbal'? These questions come up for consideration in Part One of this manuscript. In Part Two I examine whether certain disputes in ontology and over the nature of possible worlds are defective in any of the ways described in Part One. I focus mainly on the question of whether these disputes are merely verbal disputes, though I examine whether they are defective in any other ways. I conclude that neither dispute is defective in any of the senses that I make clear in Part One. Moreover, I conclude that even some defective philosophical disputes can be worth consideration under certain circumstances.

Description
Moral status questions, (who and what counts morally) are of central concern to moral philosophers. There is also a rich history of psychological work exploring the topic. The received view in psychology of moral status accounts for it as a function of other mind perception. On this view, entities are morally considerable because they are perceived to have the right sort of minds. This dissertation analyzes and tests this theory, pointing out both empirical and conceptual issues with the received view. The results presented show that important moral intuitions (for example about unjustifiable interpersonal killing) cannot be explained by appealing to other mind perception. Some alternative views of the psychology of moral status are presented, as well as avenues for further research.

Description
Concerns about the environmental and social impacts of anthropogenic climate change have called into question the efficacy, efficiency, and equity of energy systems. People committed to renewable energy transitions, and those who defend fossil-based systems, are simultaneously envisioning energy futures and seeking to build them. In the process, they are changing both energy technologies and how social life is organized around them. In this dissertation, I examine how ideas and materialities around distributed solar power become inscribed into energy policies, etched into urban landscapes, and embedded into city life. These processes engender particular kinds of embodied communities, which I define as solar communities. I study the visual and affective dimensions of emerging solar communities in Arizona and Italy using the qualitative methods of semi-structured interviews, photo-documentation, and observation. The dissertation consists of three papers. In Chapter 2, I explore how rooftops are constructed as newly productive sites for electricity generation through economic, legal, cartographic, and political negotiations, and how they become sites of struggle over who has access to them. I describe a case study in Phoenix about a proposed change in compensation for residential rooftop solar customers and the affective dynamics of a protest around it. In Chapter 3, I examine how a variety of photovoltaic applications are appearing in urban landscapes in Treviso, Italy and Flagstaff, Arizona. I investigate how aesthetic and environmental values are imbued in the physical forms those installations ultimately take, and the role that in/visibility plays in shaping these decisions. I use photography to document these emergent solar communities and argue that there is value to seeing photovoltaics in your city. In Chapter 4, I describe a workshop I led on the human dimensions and ethical trade-offs of renewable energy transitions using interactive activities and case studies from Ethiopia and Appalachia. I show how decisions about energy transitions have far-reaching impacts on people’s lives, health, the way they work, and geopolitical relationships. Together, these chapters begin to form a picture of the governance around, and visuality of, photovoltaic designs that emerge as fixtures of both landscape and society, which in turn inform solar communities.

Description
There is a lack of prior research about factors and conditions relating to the underdevelopment of infrastructure on Navajo Nation, especially from a community-centered perspective. As a Diné researcher, the intersection created via the fields of Science and Technology Studies (STS), American Indian Studies (AIS), and Diné Studies creates a means by which developmental policy and futures planning can be discussed. Through qualitative inquiry, specifically cross-case analysis, oral histories, and archival review from a Diné perspective, this work establishes the relationship between roads, energy, and Information and Communication Technologies (ICTs) in the Navajo Nation in relation to the historical underdevelopment of infrastructure on the reservation, especially from 2000 to 2020. Roads and energy infrastructures make way for ICT deployments, and together, these three infrastructures shape futures planning for the Nation, including governance decisions relating to partnerships, and internal versus external development. Relationships between infrastructural efforts, past colonial practices of the United States (U.S.), and relations between the U.S. and tribes during this era shape the development of relevant expertise within Navajo Nation entities and also impact access to and uses of significant funding opportunities available via the early 21st century American Recovery and Reinvestment Act. A Diné-centered concept of care through long-term infrastructure deployment relates tribal sovereignty and Indigenous ways of knowing to Indigenous Science and Technology Studies (STS) and suggests new directions for applied Diné studies in the field of Indigenous STS.
