Social Organization on the Web: How Sex workers Rights Organizations Engage in Activism and Advocacy Work Online

The purpose of this study was to examine how sex workers rights organizations use their websites as a site of activist and advocacy work and ask (i) how do various organizations conceptualize sex work on their websites, and to what extent do they incorporate an intersectional feminist perspective? (ii) what communication strategies are used by the four organizations to target audiences in the viewing public? (iii) what audiences do the four websites target? (iv) how do the four organizations discuss successes and challenges on their websites? (v) in what ways do sex worker right organizations use websites to further their goals? The websites of Maggie’s, POWER, and Stella attempt to embrace an intersectional feminist perspective of sex work, while PACE does not. The four organizations strategically use their websites to target audiences with diverse needs, specifically through advocacy efforts in educating the general public about the legitimacy of sexual labour. Additionally, to increase the use of the websites by sex workers, using social media platforms, such as Facebook and Twitter augment the untapped potential for creating action, mobilization, interaction, and dialogue on the websites.

A Phenomenological Study Exploring the Experiences of Men Who Work in Maternal-Newborn Nursing Positions

The aim of this study was to explore the experiences of men who choose to work in maternal-newborn nursing roles. Using a qualitative phenomenological approach, interviews were conducted with a purposeful sample of six male nurses who worked in maternal-newborn settings using a semi-structured guide. Four themes emerged: Motivation and Influences in Career Choice, Barriers to Developing Caring Confidence as Maternal-Newborn Nurses, Surviving as Men in Maternal-Newborn Nursing, and The Invisible Norms Associated with Men in Maternal-Newborn Nursing. The study generated meaning surrounding career selection and addressed motivating factors such as role modeling, life experience, and passion for the area of specialization or convenience. There is importance in understanding the experiences of men who choose to work in maternal-newborn nursing roles. Thus, this research has implications for nursing, practice, education, and research, particularly with nursing leadership, policy makers, educators, guidance counselors, and men considering maternal-newborn nursing roles.

The Influence of Burnout Symptoms on the Relationship between Work-Life Balance and Self-Rated Health

The effects of stress at work are estimated to cost Canadian employers more than 20 billion dollars annually through absenteeism, sick leave and decreased productivity. Over the past two decades, Canadians have reported higher stress levels, increased work hours and more work performed outside of normal business hours. This work-life imbalance has far-reaching repercussions–affecting an employee’s performance as well as their health. Chronic exposure to these high levels of stress can also lead to burnout. The primary purpose of this study was to determine the magnitude in which burnout symptoms influence the relationship between work-life balance and self-rated health. The secondary purpose of this study was to determine if gender and age interactions exist in the relationship between burnout, work-life balance, and self-rated health. This cross-sectional study involved secondary analysis of 220 managers, workers and human service professionals who completed an Occupational Health Clinics for Ontario Workers’ Mental Injury Toolkit (MIT) survey for the launch of the MIT. The MIT survey is a modified form of the short version of the Copenhagen Psychosocial Questionnaire and includes expanded questioning around burnout, stress, sleep troubles, cognitive, and somatic symptoms. There were no significant differences in self-rated health based on a respondent’s gender or age, indicating that no interaction of gender and age would be required. Respondents with low self-rated health reported significantly higher burnout and work-life imbalance compared to those with high self-rated health. The regression analysis demonstrated that the magnitude in which burnout mediates the relationship between work-life balance and self-rated health was 96%. These findings support previous studies that associate high levels of work-life imbalance or burnout with poor self-rated health or health outcomes. In this study, the shared variance between work-life balance and burnout also supports recent efforts to redefine the context and causes of burnout to include non-work factors. Based on our findings, the potential exists for the development of workplace health promotion strategies that address maintaining a balance between work and home as they may improve employee health and reduce burnout.

Force potentiation as a modulator of contractile performance: Implications for control of skeletal muscle force and energetics of work

This thesis investigated the modulation of dynamic contractile function and energetics of work by posttetanic potentiation (PTP). Mechanical experiments were conducted in vitro using software-controlled protocols to stimulate/determine contractile function during ramp shortening, and muscles were frozen during parallel incubations for biochemical analysis. The central feature of this research was the comparison of fast hindlimb muscles from wildtype and skeletal myosin light chain kinase knockout (skMLCK-/-) mice that does not express the primary mechanism for PTP: myosin regulatory light chain (RLC) phosphorylation. In contrast to smooth/cardiac muscles where RLC phosphorylation is indispensable, its precise physiological role in skeletal muscle is unclear. It was initially determined that tetanic potentiation was shortening speed dependent, and this sensitivity of the PTP mechanism to muscle shortening extended the stimulation frequency domain over which PTP was manifest. Thus, the physiological utility of RLC phosphorylation to augment contractile function in vivo may be more extensive than previously considered. Subsequent experiments studied the contraction-type dependence for PTP and demonstrated that the enhancement of contractile function was dependent on force level. Surprisingly, in the absence of RLC phosphorylation, skMLCK-/- muscles exhibited significant concentric PTP; consequently, up to ~50% of the dynamic PTP response in wildtype muscle may be attributed to an alternate mechanism. When the interaction of PTP and the catchlike property (CLP) was examined, we determined that unlike the acute augmentation of peak force by the CLP, RLC phosphorylation produced a longer-lasting enhancement of force and work in the potentiated state. Nevertheless, despite the apparent interference between these mechanisms, both offer physiological utility and may be complementary in achieving optimal contractile function in vivo. Finally, when the energetic implications of PTP were explored, we determined that during a brief period of repetitive concentric activation, total work performed was ~60% greater in wildtype vs. skMLCK-/- muscles but there was no genotype difference in High-Energy Phosphate Consumption or Economy (i.e. HEPC: work). In summary, this thesis provides novel insight into the modulatory effects of PTP and RLC phosphorylation, and through the observation of alternative mechanisms for PTP we further develop our understanding of the history-dependence of fast skeletal muscle function.
