Description
Teacher attrition and the migration between schools and districts can have a negative impact on quality of education and teacher performance. Novice teachers leave the profession because they are overwhelmed by the workload and responsibilities of the job. In a previous action research cycle, I found that novice teachers' perceptions of isolation and lack of opportunities to share experiences had a negative effect on teacher perceptions of efficacy. This action research project examines the effect of leveraging social media and professional learning communities to provide opportunities for a group of novice teachers to share experiences and seek advice. By addressing the challenges that novice teachers face and providing solutions for common problems, it is the hope of this researcher that highly effective teachers will remain in the classroom. The results of the study indicate that the combined use of Twitter and YouTube in collaboration with professional learning communities will improve teacher perceptions of efficacy. Teachers who participated in the social media based professional learning communities are also more likely to remain in the classroom.

Description
Bully victimization has been associated with blunted cardiovascular responses to stress as well as elevated responses to stress. The difference between these altered physiological responses to stress is largely unknown. This study explored several possible moderators to the relationship between chronic stress and future cardiac output (an indicator of increased stress) in response to future stressors. These moderators include the difference between social and physical stressors and individual levels of loneliness. Participants were administered measures of loneliness and victimization history, and led to anticipate either a "social" (recorded speech) or "non-social" (pain tolerance test ) stressor, neither of which occurred. EKG and impedance cardiography were measured throughout the session. When anticipating both stressors, loneliness and victimization were associated with increased CO. A regression revealed a three-way interaction, with change in cardiac output depending on victimization history, loneliness, and condition in the physical stressor condition. Loneliness magnified the CO output levels of non-bullied individuals when facing a physical stressor. These results suggest that non- bullied participants high in loneliness are more stressed out when facing stressors, particularly stressors that are physically threatening in nature.

Description
Social media offers a powerful platform for the independent digital content producer community to develop, disperse, and maintain their brands. In terms of information systems research, the broad majority of the work has not examined hedonic consumption on Social Media Sites (SMS). The focus has mostly been on the organizational perspectives and utilitarian gains from these services. Unlike through traditional commerce channels, including e-commerce retailers, consumption enhancing hedonic utility is experienced differently in the context of a social media site; consequently, the dynamic of the decision-making process shifts when it is made in a social context. Previous research assumed a limited influence of a small, immediate group of peers. But the rules change when the network of peers expands exponentially. The assertion is that, while there are individual differences in the level of susceptibility to influence coming from others, these are not the most important pieces of the analysis--unlike research centered completely on influence. Rather, the context of the consumption can play an important role in the way social influence factors affect consumer behavior on Social Media Sites. Over the course of three studies, this dissertation will examine factors that influence consumer decision-making and the brand personalities created and interpreted in these SMS. Study one examines the role of different types of peer influence on consumer decision-making on Facebook. Study two observes the impact of different types of producer message posts with the different types of influence on decision-making on Twitter. Study three will conclude this work with an exploratory empirical investigation of actual twitter postings of a set of musicians. These studies contribute to the body of IS literature by evaluating the specific behavioral changes related to consumption in the context of digital social media: (a) the power of social influencers in contrast to personal preferences on SMS, (b) the effect on consumers of producer message types and content on SMS at both the profile level and the individual message level.

Description
Purpose: This study examines the role of social support on adjustment to widowhood. Past research has indicated that the role of social support on adjustment to widowhood remains inconclusive, and needs further examination. This study examines the varying coping trajectories of middle-aged and retired bereaved spouses. Additionally, this study examines how bereavement stage may also influence one's adaptation to widowhood. Methods: This study used in-depth and semi-structured interviews as a means of understanding the role of social support on adjustment to widowhood. Participants were recruited through two hospice services available in a major metropolitan area in the United States. Convenient and purposive samplings are used in this study; this study will execute a grounded theory approach in order to determine the inconclusive role of social support on adjustment to widowhood. This study is contrasting between two stages- life course stages (middle aged versus retirement aged people) and bereavement stages (a year or less time following the death of a spouse versus three or more years following the death of a spouse). As a means of reducing bias and subjectivity, all data collected during the interview will be transcribed immediately. Results: Middle-aged bereaved spouses reported higher levels of motivation for adjusting positively and quickly towards widowhood due to their concern for protecting the well-being of their surviving young children compared to retired bereaved spouses. Differences between middle-aged widows and widowers have been found in this study; middle-aged widowers have a higher linkage to negative health behaviors. Retired bereaved spouses may fare better depending upon their housing location. Living in a retirement center may lower negative effects of bereavement on retired spouses' health. Conclusions: Types of social support received and expected varied between middle-aged widows and widowers. Gender norms may influence the type of social support widows and widowers receive. Middle-aged widowers are less likely to receive emotional support which may explain their higher linkage to negative health behaviors. Bereavement stage and housing location may be the key factors that influence widowhood trajectories of retired bereaved spouses. Living in a retirement center may lower the negative effects of bereavement on overall health.

Description
Research has demonstrated that temperature and relative humidity substantially influence overall perceptions of indoor air quality (Fang, Clausen, & Fanger, 1998). This finding places temperature quality as a high priority, especially for vulnerable adults over 60. Temperature extremes and fluctuation, as well as the perception of those conditions, affect physical performance, thermal comfort and health of older adults (Chatonnet & Cabanac, 1965, pp. 185-6; Fumiharu, Watanabe, Park, Shephard, & Aoyagi, 2005; Heijs & Stringer, 1988). The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) and the International Organization for Standardization (ISO) have developed thermal-comfort standards for working-age, healthy individuals. None of these standards address the physiological and psychological needs of older adults (ASHRAE Standard 55, 2010; ISO-7730, 2005). This dissertation investigates the impacts of thermal conditions on self-reported health and perceived comfort for older adults, hypothesizing that warmer and more-table indoor thermal conditions will increase the health and perceived comfort of these adults. To this end, a new set of thermal comfort metrics was designed and tested to address the thermal preferences of older adults. The SENIOR COMFORT Metrics 2013 outlined new thresholds for optimal indoor high and low temperatures and set limits on thermal variability over time based on the ASHRAE-55 2010 model. This study was conducted at Sunnyslope Manor, a multi-unit, public-housing complex in the North Phoenix. Nearly 60% (76 of 118) of the residents (aged 62-82) were interviewed using a 110-question, self-reporting survey in 73 apartment units. A total of 40 questions and 20 sub-questions addressing perceptions of comfort, pain, sleep patterns, injuries, and mood were extracted from this larger health condition survey to assess health and thermal comfort. Indoor environmental thermal measurements included temperature in three locations: kitchen, living area, and bedroom and data were recorded every 15 minutes over 5 full days and 448 points. Study results start to indicate that older adults for Sunnyslope Manor preferred temperatures between 76 and 82.5 degrees Fahrenheit and that lower temperatures as outlined by ASHRAE-55 2010 increases the rate of injuries and mood changes in older adults among other findings.

Description
This qualitative case study of 12, eighteen to twenty-four-year-olds from seven countries provided insight into the learning practices on an art-centered, social media platform. The study addressed two guiding questions; (a) what art related skills, knowledge, and dispositions do community members acquire using a social media platform? (b), What new literacy practices, e.g., the use of new technologies and an ethos of participation, collective intelligence, collaboration, dispersion of abundant resources, and sharing (Knobel & Lankshear, 2007), do members use in acquiring of art-related skills, concepts, knowledge, and dispositions? Data included interviews, online documents, artwork, screen capture of online content, threaded online discussions, and a questionnaire. Drawing on theory and research from both new literacies and art education, the study identified five practices related to learning in the visual arts: (a) practicing as professional artists; (b) engaging in discovery based search strategies for viewing and collecting member produced content; (c) learning by observational strategies; (d) giving constructive criticism and feedback; (e) making learning resources. The study presents suggestions for teachers interested in empowering instruction with new social media technologies.

Description
In 1890, the State of Nevada built the Stewart Indian School on a parcel of land three miles south of Carson City, Nevada, and then sold the campus to the federal government. The Stewart Indian School operated as the only non-reservation Indian boarding school in Nevada until 1980 when the federal government closed the campus. Faced with the challenge of assimilating Native peoples into Anglo society after the conclusion of the Indian wars and the confinement of Indian nations on reservations, the federal government created boarding schools. Policymakers believed that in one generation they could completely eliminate Indian culture by removing children from their homes and educating them in boarding schools. The history of the Stewart Indian School from 1890 to 1940 is the story of a dynamic and changing institution. Only Washoe, Northern Paiute, and Western Shoshone students attended Stewart for the first decade, but over the next forty years, children from over sixty tribal groups enrolled at the school. They arrived from three dozen reservations and 335 different hometowns across the West. During this period, Stewart evolved from a repressive and exploitive institution, into a school that embodied the reform agenda of the Indian New Deal in the 1930s. This dissertation uses archival and ethnographic material to explain how the federal government's agenda failed. Rather than destroying Native culture, Stewart students and Nevada's Indian communities used the skills taught at the school to their advantage and became tribal leaders during the 1930s. This dissertation explores the individual and collective bodies of Stewart students. The body is a social construction constantly being fashioned by the intersectional forces of race, class, and gender. Each chapter explores the different ways the Stewart Indian School and the federal government tried to transform the students' bodies through their physical appearance, the built environment, health education, vocational training, and extracurricular activities such as band and sports.

Description
This dissertation research analyzes the vernacular cosmopolitan praxis of Muslim women in transnational cyberspaces related to topical and collective action networks, in an effort to detangle cosmopolitanism from its Western biases and to move away from studies of online Muslim populations based on geographical locations or homogenous networks, linking individuals through their religious practices or consumption of religious knowledge. Through highlighting praxes rather than contexts, this dissertation disrupts the East/West binary and challenges stereotypes ascribed to Muslim women. One of the research questions related to the cosmopolitan praxis of Muslim women is the following: in what ways do Muslim women engage with "others" online and contribute to bridging dissimilar people? Findings suggest that the social media use of Muslim women contributes to their subtle resistance against communal norms and, although it can serve as an extension to their voices, some of their voices are more readily mediated than others. I employ a connective content analysis methodology to put various datasets associated with topics and collective actions related to Muslim women into conversation. The methodology not only highlights consistencies in the qualitative themes that were iteratively developed through the analyses of the datasets, but also more tangible connections related to social media users, topics, and content. Consequently, this thesis is as much concerned with recasting Western-oriented conceptualizations of cosmopolitanism as it is with how networks dynamics foster and constrain cosmopolitan praxis because digital networks have the extraordinary capacity to link dissimilar people beyond any other type of medium. One of the research questions related to the methodology is: how do network dynamics facilitate and constrain cosmopolitan praxis? The substantive chapters related to the datasets discuss various forms of cosmopolitan praxis that were identified in the analysis: social media use by Muslim women that expands the connective memory, which could contribute to dispelling stereotypes ascribed to them; activism that addresses universal concerns related to women's rights regardless of context; dialogically devising basic standards of social conduct and gender relations; and expressions of tolerance toward divergent views, including alternative interpretations of Islamic beliefs and practices.

Description
This study was designed to investigate whether workplace positivity of full-time workers was related to health ratings. Positivity was conceptualized by a high rating of perceived work-performance, and work-engagement as defined by the Utrecht Work-Engagement Scale, including vigor, dedication, and absorption (Schaufeli, & Bakker, 2004). Health was measured utilizing the RAND SF-36 health survey including the eight subscales: overall, general health, physical and social functioning, emotional well-being, role limitations due to physical health or emotional problems, energy or fatigue, and bodily pain. All measures were collected simultaneously. It was predicted that perceived work-performance and all measures of work-engagement are positively associated with the aforementioned health ratings. Multiple regression analyses revealed that higher (positive) perception of work-performance and vigor were positively related to health ratings. Absorption was negatively related to health ratings. Dedication was only negatively related to physical functioning. These findings suggest that not all measures of positivity in the workplace are related to better health. Implications and future directions are discussed.

Description
Attack of the Fake Geek Girls: Challenging Gendered Harassment and Marginalization in Online Spaces applies feminist, gender, and rhetorical theories and methods, along with critical discourse analysis, to case studies of the popular online social media platforms of Jezebel, Pinterest, and Facebook. This project makes visible the structural inequities that underpin the design and development of internet technologies, as well as commonplace assumptions about who is an online user, who is an active maker of internet technologies, and who is a passive consumer of internet technologies. Applying these critical lenses to these inequities and assumptions enables a re-seeing of commonplace understandings of the relationship between gender performativity and digital cultures and practices. Together, these lenses provide a useful set of tools for methodically resisting the mystique of technologies that are, simultaneously, represented as so highly technical as to be opaque to scrutiny, and as ubiquitous to everyday life as to be beneath critical examination.
Through a close reading of the discourses surrounding these popular social media platforms and a rhetorical analysis of their technological affordances, I documented the transference of gender-biased assumptions about women's roles, interests, and competencies, which have historically been found in face-to-face contexts, to these digital spaces. For example, cultural assumptions about the frivolity of women's interests, endeavors, issues, and labors make their way into digital discourse that situates the online practices of women as those of passive consumers who use the internet only to shop and socialize, rather than to go about the serious, masculine business of making original digital content.
This project expands on existing digital identity and performativity research, while applying a sorely needed feminist critique to online discourses and discursive practices that assume maleness and masculinity as the default positionality. These methods are one approach to addressing the pressing problems of online harassment, the gender gap in the technology sector, and the gender gap in digital literacies that have pedagogical, political, and structural implications for the classroom, workplace, economic markets, and civic sphere.
