This thesis is a creative one, comprised of eight short stories which deal with a variety of subjects. All of the material is concerned with personal or vicarious experience.

This study first tests the factors influencing the willingness to express opinions online. Guided by the spiral of silence theory, the research used a survey to test whether fear of isolation and opinion congruency work online. Second, the study explores how psychological constructs, including self-efficacy, collective efficacy, and proxy efficacy affect the willingness to express disagreement. A 2 × 2, verbal persuasion × vicarious experience, experiment was applied. Third, this study also conducted a content analysis to measure disagreement expressions in online newspapers and test how these expressions affect opinion quality and online discussion involvement. The survey study (N=321) showed that while fear of isolation online negatively predicts the willingness to express individual opinions, opinion climate congruency is not associated with the willingness. The online experiment demonstrated that mastery experience and verbal persuasion positively influence self-efficacy, but vicarious experience's effect was not confirmed. Self-efficacy plays the most salient role in predicting whether one selects to express disagreement online. The content analysis (N=1,288) of the discussion threads demonstrated that disagreement expression is widespread in the online newspaper forums analyzed, and such expression positively influences reasoned opinions and political discussion engagement.

Background. In Canadian baccalaureate nursing education, many schools pair their nursing students with a nurse preceptor to complete a consolidation placement in their final year of studies. The preceptor plays an important role in students’ learning and their success in the program. Although there are many factors that may influence preceptors’ ability to be successful in the role, the literature suggests that self-efficacy may affect their performance as a preceptors and may have an impact on students’ learning and their preceptorship experience. Self-efficacy is defined as a person’s confidence in their abilities to complete a task or goal. As such, preceptors with greater self-efficacy may be more effective in their role and may have a positive impact on students’ learning. Therefore, it is important to assess factors that influence preceptors’ self-efficacy as this knowledge could help inform and target the development of preceptor training programs, preceptor selection criteria and preceptor supports. Objectives. The purpose of this thesis is to explore the factors that affect the self-efficacy of preceptors. Five factors were investigated, including: (1) nursing experience, (2) preceptor experience, (3) vicarious preceptor experience, (4) preceptor training, and (5) the personality trait neuroticism. These variables are derived from Bandura’s (1986) theory of self-efficacy. Design. This study was conducted using a cross-sectional, non-experimental study design. Methods. A total of 95 nurse preceptors participated in the study by completing an online survey and were recruited using multiple strategies, including social media. The survey was comprised of demographic questions, a measure of the Big-Five personality traits, and a measure of clinical teaching self-efficacy. Correlation, independent t-tests and ANOVAs were done to analyze the data. Results. A statistically significant correlation was found between self-efficacy and two independent variables: nursing experience (r = 0.33, p < 0.01) and the personality trait of neuroticism (r = -0.21, p = .05). Additionally, self-efficacy was correlated with agreeableness (r = 0.22, p = .03) and age (r = 0.41, p < 0.01). A statistically significant difference in self-efficacy was found between diploma and bachelor degree nurses (mean difference = 0.37, p = .02), and bachelor degree and graduate degree nurses (mean difference = -0.45, p = .02). Conclusion. Three key results were found to influence the self-efficacy of nurse preceptors. This knowledge can be incorporated into preceptor training, preceptor support and the preceptor selection process.

Optimistiese self-evaluasies oor die vermoë om take uit te voer is belangrik vir sukses in verskeie aspekte van menswees. Wanneer mense sulke self-evaluasies doen en selfdoeltreffendheids-persepsies vorm maak hulle van inligting uit verskeie bronne gebruik. Volgens teorieë wat spesifiek verband hou met self-evaluasie is mense tydens die vorming van sulke persepsies omtrent die self veral afhanklik van inligting bekom deur sosiale vergelyking. Hierteenoor beklemtoon teorieë wat meer met selfdoeltreffendheid verband hou, die belangrikheid van self-verwysende inligting soos gevorm tydens prestasie-ervarings. Die doel met hierdie navorsing is om die ordening van die bronne van inligting, wat tydens die vorming van selfdoeltreffendheids-persepsies gebruik word, te ondersoek. Die resultate sal bydra om belangrike vrae te beantwoord oor die voorbereiding van mense vir die uitvoering van uitdagende take. In 'n eksperiment (N=1 723) wat op 'n Solomon-vier-groep-ontwerp geskoei is, is drie vorme van inligting wat persepsies kan beïnvloed aan drie eksperimentele groepe verskaf terwyl daar vyf kontrolegroepe was. Die effek van die ingrepe is met 'n vraelys gemeet. Die resultate toon dat selfdoeltreffendheidspersepsies meer deur selfverwysende inligting as deur sosiale vergelykings-inligting beïnvloed word. Dit is ook bevind dat die verskaffing van addisionele inligting nie 'n kumulatiewe effek tydens die vorming van selfdoeltreffendheidspersepsies het nie. Die implikasies van die resultate ten opsigte van die praktyk en teoretiese beskouinge is in die laaste instansie bespreek. / Optimistic self-evaluation regarding the ability to cany out tasks is important for success in various fields ofhuman endeavour.

According to theories related to self-evaluation, people engaged in forming such perceptions about themselves largely depend on information gained through social comparison.

The purpose of this research is to examine the collation of sources of information used in forming self-efficacy perceptions. The results will help to answer important questions about preparing people to perform challenging tasks. In an experiment (N=l 723) modelled on the Solomon Four Group Design, three types of information likely to influence perceptions were supplied to three experimental groups, while there were five control groups. The effects of the interventions were measured by means of a questionnaire. Results confirmed that perceptions of self-efficacy are more profoundly influenced by self-referenced information than by social comparisons. It was also found that additional information did not have a cumulative effect dming the forming of self -efficacy perceptions.

Background. The study was prompted by observation that failure to obtain a positive postsecondary destination is significantly more prevalent in young people living in areas of greater social deprivation, and in males rather than females. Previous studies have shown that this could be linked to differences in social cognitive factors. However, these studies have been mainly correlational and no comprehensive assessment instrument was found to assess preparedness for the postsecondary transition. Aims. The present study examines senior high school student’s perceptions of the personal, behavioural and environmental factors that affect them as they prepare to leave school. It reveals the structure of these factors and how they vary with regard to social deprivation and gender. Sample. The participants were 1044 senior high school students (573 males and 471 females) who attended six urban high schools. Method. A pre-empirical, 50-item assessment instrument was constructed based on the literature review to identify the wide range of factors previously shown to be relevant to achievement of a positive postsecondary destination. This was then administered to participants. Results. Factor analysis indicated that young people’s perceptions about leaving school were best represented by thirteen factors. An ANOVA model indicated that young people living in areas of higher deprivation reported significantly lower levels of positive postsecondary destination self-efficacy belief, less experience of vicarious career success, less performance of career development tasks, greater perception of career barriers, greater endorsement of a fixed career mindset, and fewer career scaffolding attachments. Males, compared to females, reported less experience of past career success, and fewer career scaffolding attachments. However, despite being at greater risk of a negative postsecondary destination, males reported higher levels of positive postsecondary destination self-efficacy belief, greater experience of positive career-related emotional arousal, greater ability to set career goals, and greater levels of career optimism. Conclusion. Twelve significant main effects on the measured social cognitive factors have the potential to contribute to an explanation of why failure to obtain a positive postsecondary destination is more prevalent in young people living in areas of greater social deprivation, and in males rather than females. A new assessment instrument has been produced to inform an ongoing exploratory process to design, target and evaluate educational interventions to improve postsecondary destinations for all. Increasing internal consistency, external validity and generalisability of findings are all desirable. Some future interventions are proposed on the basis of the results, including greater use of positive career role models in career development programmes, career mindset retraining for high school students, and psycho-education on attachment-fostering behaviours for parents and professionals.
