Description
Though it is a widespread adaptation in humans and many other animals, parental care comes in a variety of forms and its subtle physiological costs, benefits, and tradeoffs related to offspring are often unknown. Thus, I studied the hydric, respiratory, thermal, and fitness dynamics of maternal egg-brooding behavior in Children's pythons (Antaresia childreni). I demonstrated that tight coiling detrimentally creates a hypoxic developmental environment that is alleviated by periodic postural adjustments. Alternatively, maternal postural adjustments detrimentally elevate rates of egg water loss relative to tight coiling. Despite ventilating postural adjustments, the developmental environment becomes increasingly hypoxic near the end of incubation, which reduces embryonic metabolism. I further demonstrated that brooding-induced hypoxia detrimentally affects offspring size, performance, locomotion, and behavior. Thus, parental care in A. childreni comes at a cost to offspring due to intra-offspring tradeoffs (i.e., those that reflect competing offspring needs, such as water balance and respiration). Next, I showed that, despite being unable to intrinsically produce body heat, A. childreni adjust egg-brooding behavior in response to shifts in nest temperature, which enhances egg temperature (e.g., reduced tight coiling during nest warming facilitated beneficial heat transfer to eggs). Last, I demonstrated that A. childreni adaptively adjust their egg-brooding behaviors due to an interaction between nest temperature and humidity. Specifically, females' behavioral response to nest warming was eliminated during low nest humidity. In combination with other studies, these results show that female pythons sense environmental temperature and humidity and utilize this information at multiple time points (i.e., during gravidity [egg bearing], at oviposition [egg laying], and during egg brooding) to enhance the developmental environment of their offspring. This research demonstrates that maternal behaviors that are simple and subtle, yet easily quantifiable, can balance several critical developmental variables (i.e., thermoregulation, water balance, and respiration).

Description
The Holocaust and the effects it has had upon witnesses has been a topic of study for nearly six decades; however, few angles of research have been conducted relating to the long-term effects of the Holocaust upon the children and grandchildren of Holocaust survivors--the After Generations. The After Generations are considered the proof--the living legacies--that their parents and grandparents survived. Growing up with intimate knowledge of the atrocities that occurred during the Holocaust, members of the After Generations not only carry with them their family's story, but also their own vicarious experience(s) of trauma. From this legacy comes a burden of responsibility to those who perished, their survivor parents/grandparents, the stories that were shared, as well as to future generations. Using grounded theory method, this study not only explores the long-term effects of the Holocaust upon members of the After Generations, but what it means to responsibly remember the stories from the Holocaust, as well as how individuals might ethically represent such stories/memories. Findings that developed out of an axial analysis of interview transcripts and journal writing, as well as the later development of a performance script, are embodied in a manner that allows the actual language and experiences of the participants to be collectively witnessed both symbolically and visually. Through their desire to remember, members of the After Generations demonstrate how they plan to carry on traditions, live lives that honor those that came before them, and maintain hope for the future. In so doing, the stories shared reveal the centrality of the Holocaust in the lives of members of the After Generations through their everyday choices to responsibly and actively remember through their art, writings, life-work, as well as from within their work in their local communities. Such acts of remembrance are important to the education of others as well as to the construction and maintenance of the After Generations' identities. The representation of these voices acts as a reminder of how hatred and its all-consuming characteristics can affect not only the person targeted, but multiple generations, as well.

Description
This narrative study sought to understand the socialization experiences of Hispanic entrepreneurs. While several studies have explored socialization and work-life wellness, few have focused specifically on Hispanics or entrepreneurs. A total of 25 participants were formally interviewed for this study including 16 entrepreneurs and 9 of their family members. Data were also collected through participant observation in which 210 participants were observed at several venues. Participants were recruited from three Southwestern states including: Arizona, Colorado, and Texas. The study employed qualitative interpretive methods to collect and analyze data. Research questions focused on the socialization experiences Hispanic entrepreneurs' reported, how they narrated the ways in which these experiences influenced their work-lives as entrepreneurs, and what they and their family members reported about the relationship between family and work. Results indicate Hispanic entrepreneurs were exposed to work at very young ages, acquired a variety of skills (e.g. sales and leadership) that transferred to their careers as entrepreneurs, and developed coping skills which helped them deal with business and personal hardships. Moreover, participants noted the ways in which faith, positive self-talk, and emotional labor played a role in their work lives. Finally, this research extends current constructions of care and what constitutes work and quality family time.

Description
Overwork is a long documented social problem in the United States linked to an abundance of negative outcomes. Typically this issue has been addressed organizationally at the individual level or socially as an economic structural problem. While both approaches are valid in their own ways, missing from these angles is an approach to overwork from an individual perspective. This study explores overwork from the perspective of seasonal workers in Glacier National Park who typically work for the National Park Service five months and spend the rest of the year recreating. Using qualitative interviews and observations, this piece investigates a seasonal mentality towards work in terms of agency and trust, conceptions and practices of work and life, and in terms of embodiment and spirituality. Grounded theory methods were used to develop an axiomatic analysis which informs a poetic and narrative expression of findings in concert to the discussion and implications of the study. The findings of this study illustrate how seasonal workers present a fascinating alternative to traditional work arrangements in a capitalist system. They possess a unique approach to work and life that foregrounds life experience, freedom, and process as opposed to material goods or stability. They tend to approach work and life as an integrated and holistic pursuit as opposed to a segregated and problematic enterprise. And they tend to approach their work as an embodied and spiritual craft as opposed to something accomplished quickly and efficiently for the economic benefit of the organization. Implications of this research suggest that agency and trust maintain a deeply interconnected and dialectical relationship which agents navigate as they build towards ontological security; that re-conceptualizing work-life as "life first" has potential for fundamentally reshaping the ways life (and work) get experienced; and that divisions between minds and bodies as they have been typically structured between white and blue collar work might be interrupted via the inclusion of the human spirit at work. These findings interrupt common practices of overwork in different ways but primarily function as a reminder that ways of thinking coincide with ways of living and working.

Description
Buddhism is thriving in US-America, attracting many converts with college and post-graduate degrees as well as selling all forms of popular culture. Yet little is known about the communication dynamics behind the diffusion of Buddhist religious/spiritual traditions into the United States. Religion is an underexplored area of intercultural communication studies (Nakayama & Halualani, 2010) and this study meets the lacuna in critical intercultural communication scholarship by investigating the communication practices of US-Americans adopting Asian Buddhist religious/spiritual traditions. Ethnographic observations were conducted at events where US-Americans gathered to learn about and practice Buddhist religious/spiritual traditions. In addition, interviews were conducted with US-Americans who were both learning and teaching Buddhism. The grounded theory method was used for data analysis. The findings of this study describe an emerging theory of the paracultural imaginary -- the space of imagining that one could be better than who one was today by taking on the cultural vestments of (an)Other. The embodied communication dynamics of intercultural exchange that take place when individuals adopt the rituals and philosophies of a foreign culture are described. In addition, a self-reflexive narrative of my struggle with the silence of witnessing the paracultural imaginary is weaved into the analysis. The findings from this study extend critical theorizing on cultural identity, performativity, and cultural appropriation in the diffusion of traditions between cultural groups. In addition, the study addresses the complexity of speaking out against the subtle prejudices in encountered in intercultural communication.

Description
How is sauerkraut like a poem? As human understanding of microbes deepen, humans find themselves embedded in a microbial matrix. I extend privileging this ecocultural embeddedness with microbes and the deep ecological process of fermentation by microbes to explore creative inquiry. This work offers two primary outcomes. First, I offer an articulation of proposed methods for use within a posthumanism as research methodology, including methods for working with nonhuman research participants, especially microbial ones. These proposed methods include touching grass, eco-listening, and guthinking as well as expansions of qualitative research methods to encompass nonhuman participants, especially in interviewing and ontological shifts. Second, I present a creative fermented framework for understanding creative inquiry as embedded in understandings of a microbial matrix and metaphorical fermentation practices. Creative fermented framework concepts include incubation, environmental input, and composting, with specific proposed methods ranging from creative procrastination to feeding the starter to composting turds. As a whole, I offer the fermentation orientation, which is a worldview of attending to microbes and fermentation processes as they relate to processes of inquiry, epistemology, and methodology.

Description
For fifty years, inquiry has attempted to capture how groups of people experience microaggression phenomena through multiple methodological and analytic applications grounded in psychology-influenced frameworks. Yet, despite theoretical advancements, the phenomenon has met criticisms trivializing its existence, falsifiability, and social significance. Unpacking possible interactive factors of a microaggressive moment invites a revisitation of the known and unknown pragmatic conditions that may produce and influence its discomforting situational “content.” This study employs an intentional, game-theoretic methodology based on brief, publicly-recorded, everyday conversation segments. Conversation segments of social interactions provide a means to conduct a mathematically-solid, computationally-tractable analysis of explaining what is happening during encounters where disability microaggressions are likely the result of partial (non)cooperation between communicators. Such analysis extends the microaggression research program (MRP) by: (1) proposing theoretical consequences for conversational repair phenomena, algorithmic programming, and experimental designs in negotiation research; and (2) outlining practical approaches for preventing microaggressions with new communication pedagogy, anti-oppression/de-escalation training programs, and calculable, focus-oriented psychotherapy. It concludes with an invitation for scholars to “be” in ambiguity so that they may speculate possible trajectories for the study of microaggressions as a communicative phenomenon.

Description
In this dissertation, I explore the researched and lived potential afforded by the principle of interrelationality from the culturally situated Asian approach espoused in Yoshitaka Miike’s (2008, 2012, 2013, 2017) metatheory of Asiacentricity and Kuan-Hsing Chen’s (2010) Asia as method. This work addresses the limitations of binary logics as a Eurocentric modern tool and proposes an Asiacentric dynamic orientation to research. I draw on Asiacentricity’s principles of harmony, interrelatedness, feelings, and flux to guide an ongoing experimentation to find meaning in relation to others in a Western context. I turn to Asia as method as an additional point of inspiration to transform knowledge production by looking to Asiacentric social ontologies to inform my methodology. Inspired by Chinese medicinal dynamic theories of practice rooted in Asian philosophy, I propose an ethico-onto-epistemological approach to research where researchers approach work through equal measures of theoretical absorption, observation of theory in practice, and an active personal exploration of theoretical application, treating one’s data with inherent energetic potential. This work found that orientations of complementarity and interdependent poiesis are crucial to engage in Asiacentric relationality, and that an Asiacentric methodology is guided by tenets of living one’s research, engaging the dynamism of the world and oneself as researcher, and embracing connectedness through an acceptance of incompletion.

Description
Why do many animals possess multiple classes of photoreceptors that vary in the wavelengths of light to which they are sensitive? Multiple spectral photoreceptor classes are a requirement for true color vision. However, animals may have unconventional vision, in which multiple spectral channels broaden the range of wavelengths that can be detected, or in which they use only a subset of receptors for specific behaviors. Branchiopod crustaceans are of interest for the study of unconventional color vision because they express multiple visual pigments in their compound eyes, have a simple repertoire of visually guided behavior, inhabit unique and highly variable light environments, and possess secondary neural simplifications. I first tested the behavioral responses of two representative species of branchiopods from separate orders, Streptocephalus mackini Anostracans (fairy shrimp), and Triops longicaudatus Notostracans (tadpole shrimp). I found that they maintain vertical position in the water column over a broad range of intensities and wavelengths, and respond behaviorally even at intensities below those of starlight. Accordingly, light intensities of their habitats at shallow depths tend to be dimmer than terrestrial habitats under starlight. Using models of how their compound eyes and the first neuropil of their optic lobe process visual cues, I infer that both orders of branchiopods use spatial summation from multiple compound eye ommatidia to respond at low intensities. Then, to understand if branchiopods use unconventional vision to guide these behaviors, I took electroretinographic recordings (ERGs) from their compound eyes and used models of spectral absorptance for a multimodel selection approach to make inferences about the number of photoreceptor classes in their eyes. I infer that both species have four spectral classes of photoreceptors that contribute to their ERGs, suggesting unconventional vision guides the described behavior. I extended the same modeling approach to other organisms, finding that the model inferences align with the empirically determined number of photoreceptor classes for this diverse set of organisms. This dissertation expands the conceptual framework of color vision research, indicating unconventional vision is more widespread than previously considered, and explains why some organisms have more spectral classes than would be expected from their behavioral repertoire.

Description
In the countries of Eastern Europe, the recent history of the communist regimes creates a context rich in various and often times contradictory remembering practices. While normative discourses of memory enacted in official forms of memory such as museums, memorials, monuments, or commemorative rituals attempt to castigate the communism in definite terms, remembering practices enacted in everyday life are more ambiguous and more tolerant of various interpretations of the communist past. This study offers a case study of the ways in which people remember communism in everyday life in Romania. While various inquiries into Eastern Europe's and also Romania's official and intentional forms of memorializing communism abound, few works address remembering practices in their entanglements with everyday life. From a methodological point of view, this study integrates a grounded methodology approach with a rhetorical sensitivity to explore the discourses, objects, events, and practices of remembering communism in Bucharest, the capital city of Romania. In doing so, this inquiry attends not only to the aspects of the present that animate the remembering of communism, but also and more specifically to the set of practices by which the remembering process is performed. The qualitative analysis revealed a number of conceptual categories that clustered around three major themes that describe the entanglements of remembering activities with everyday life. Relating the present to the past, sustaining the past in the present, and pursuing the communist past constitute the ways in which people in Romania live their relationships with the communist past in a way that reveals the complex interplay between private and public forms of memory, but also between the political, social, and cultural aspects of the remembering process. These themes also facilitate a holistic understanding of the rhetorical environment of remembering communism in Romania.
