A Longitudinal Examination of Bidirectional Associations between Subjective Sleep Characteristics and Psychosocial Functioning among University Students

A number of studies have found a significant link between sleep and psychosocial functioning among university students. A critical examination of this literature, however, indicates that one important gap within the literature is the need for longitudinal studies that specifically test for bidirectional associations between these two constructs. The main purpose of my dissertation was to address this gap by conducting three studies that examined bidirectional associations between sleep and psychosocial functioning among a sample of university students. Participants were 942 (71.5% female) undergraduate students enrolled at a Canadian university, who completed survey assessments annually for three consecutive years, beginning in their first year of university. In the first study, I assessed bidirectional associations between two sleep characteristics (sleep quality and sleep duration) and three psychosocial functioning variables (academics, friendship quality, and intrapersonal adjustment). Results based on cross-lagged models indicated a significant bidirectional association between sleep quality and intrapersonal adjustment, such that more sleep problems predicted more negative intrapersonal adjustment over time, and vice versa. Unidirectional associations indicated that both higher academic achievement and more positive friendship quality were significant predictors of less sleep problems over time. In the second study, in which I examined bidirectional associations between sleep and media use, results provided support only for unidirectional associations; such that more sleep problems predicted increases in both time spent watching television and time spent engaged in online social networking. In the third study of my dissertation, in which I examined social ties at university and sleep quality, results indicated a significant bidirectional association, such that more positive social ties predicted less sleep problems over time, and vice versa. Importantly, emotion regulation was a significant mediator of this association. Findings across the three studies, highlight the importance of determining the direction of effects between different sleep characteristics and various aspects of university students’ psychosocial functioning, as such findings have important implications for both methodology and practice. A better understanding of the nature of the associations between sleep and psychosocial functioning will equip students, parents and university administrators with the tools necessary to facilitate successful adjustment across the university years.

University Students' Perceptions of Myocardial Infarction Patients

This study examined: (1) whether individuals who were described as having a myocardial infarction (MI) were perceived differently compared to individuals who were described as having rheumatoid arthritis or individuals who had no health condition; and (2) whether individuals described as engaging in exercise following an MI were perceived more positively than those described as not engaging in exercise following an MI or for whom no mention of exercise was made. University students (n = 473) were randomly assigned 1 of 10 target conditions. They completed demographic information, read a target description, created an image of that target in their head, and then rated that target on physical and personality characteristics. The results showed that the MI targets were perceived more negatively than the arthritis targets and healthy controls, specifically on the physical characteristics. Further, engaging in exercise following an MI helped to reduce the negative perceptions associated with MIs.

The Effects of a Social-Evaluative Body Image Threat on Shame, Social Physique Anxiety, Body Dissatisfaction and Cortisol Responses in University Men

Men struggle with body image concerns particularly related to the desire to be muscular. In women, social-evaluative body image threats have been linked to increased shame and cortisol responses, consistent with social self-preservation theory (SSPT), but no research has investigated these responses in men. Men (n = 66) were randomly assigned to either a social-evaluative threat (SET) or non-social-evaluative threat (N-SET) condition. Participants provided saliva samples and completed body shame, body dissatisfaction and social physique anxiety measures prior to and following their condition, during which anthropometric and strength measures were assessed. Results indicated men in the SET condition had higher body shame, social physique anxiety, and body dissatisfaction and had higher levels of cortisol than men in the N-SET condition post-social-evaluative threat. These findings, consistent with SSPT, suggest that social-evaluative body image threats may lead to increased body shame and social physique anxiety, greater body dissatisfaction and higher cortisol levels.

Collegial Self-Governance for Professional Librarians: A Look at the Advantages of the Establishment of a Library Council and its Role in the Lives of the Librarians in the Brock University Faculty Association

The ability to perform collegial governance is a cornerstone of modern universities in the United States and Canada. This idea of governance is well practiced among faculty members but is not often practiced to the same extent with librarians in those same institutions. In this chapter, I will look at a popular form of collegial governance called the Library Council. Further, I will examine how the Library Council at Brock University has enabled librarians there to perform meaningful collegial self-governance.

ESL Collections, University Libraries, and Internationalization

This research study examines the content, types of materials, locations, and library collection development policies concerning ESL (English as a second language) materials collections on university campuses in the United States and Canada. ESL learning materials are defined in this study as those materials supporting adult learners who are non-native speakers of English in a higher education setting. The purpose of this study is to describe the content and types of materials in these collections, to learn where these collections are typically housed on university campuses, to discover what collection development policies may inform the building of these collections, and to explore the potential significance of these collections for university libraries. The overriding question that informs this study is the following: Can involvement with ESL collections serve as a way for university libraries to participate in internationalization by supporting the language needs of international students?

University Faculty Members’ Understanding of Their Role: Identity, Power, and Silence

This qualitative study was conducted to explore tenured faculty members’ understandings of their roles as professors. Tenure is an institutional means to enact academic freedom, which allows tenured faculty members to investigate topics of their choosing free from external influence. Academic freedom also enables faculty members to be public intellectuals who shape and critique social policies and make knowledge assertions. In effect, the faculty members are institutionally protected to speak truth to power. Purposeful sampling of 9 participants from 2 universities yielded 3 major themes: professorial identity (shaped by such factors as career stage, university culture, and faculty affiliation), professorial power (powers that participants experienced as well as the ways in which they exercised power), and professorial silencing (as a response to fiscal realities coupled with numerous governance issues). While participants were cognizant of the powers that affected their freedoms, they were less aware of the ways in which their position afforded them powers. Subtle but more potent forms of power were at play for tenured professors, but the participants saw themselves as having to work within institutional and financial constraints that limited their freedom to speak out on controversial issues. Faculty members were, thus, silenced and at times chose to self-silence. The context of the present-day university, governance models, and the financial issues affecting universities and departments worked in concert to silence this critical voice in society.

The Experience of (In)Accessibility at University: What Disabled Graduate Students Reveal

Although the number of disabled students entering graduate school has increased in recent years, research pertaining to graduate students with disabilities remains underdeveloped. The purpose of this generic qualitative study is to better understand the experiences of (in)accessibility from the perspectives of three graduate students who self-identify as disabled or as having a disability(s) at one mid-sized university in Southern Ontario. The theoretical orientation was shaped by a social model of disability. The study was focused around the following major research question: What have been the experiences of (in)accessibility for three graduate students who self-identify as disabled or as having a disability(s) at one mid-sized university in Southern Ontario? Subquestions were organized around subcategories, such as (a) experiences related to accessibility, (b) experiences related to inaccessibility, and (c) insights related to future recommendations to enhance accessibility. The study found that (in)accessibility at university was related to (a) specific places on campus, (b) specific people on campus, and (c) the culture of awareness. A variety of educational initiatives were recommended to foster accessible practices and to develop a more accepting and disability-friendly culture on campus. Based on these findings, the Trickledown Effect Model was proposed as a means for promoting accessibility at university.
