To address the pervasive concerns of educators about the social and emotional effects of mathematics acceleration on students and the paucity of findings on those issues, 6 students who had participated in 6 years of accelerated mathematics courses were purposefully identified and interviewed in this longitudinal study. Through a qualitative research design, using phenomenological methods, and accompanying descriptive statistics, the author elicited the students’ descriptions of their learning experiences. Major findings in this study were that all students described great benefits from the experience, negative effects were minor, and key factors contributing to success were work ethic, motivation, parents and teachers. The researcher examines a subset of able and promising students who experienced increased mathematics expectations, and she gives parents, educators and policymakers insight into how that population responded to those challenges. In the ever-shifting arena of higher learning expectations for all students under No Child Left Behind legislation and the poor showing of U.S. students on international tests, these results provide information about the possible responses that other students, those struggling and unmotivated, might have to those demands.

Background: Across North America, smoking prevalence is highest among young adults (YAs). Understanding the cessation behaviours of YAs is critical given their higher smoking rates; however, there is a paucity of prospective studies on YA cessation from a population-based sample of smokers. Objectives: This study characterizes younger and older adult smokers as well as identifies the rate of making a quit attempt (QA) and smoking cessation among a representative sample of younger and older adult smokers. Guided by the Social Cognitive Theory (SCT), this study also examines the interpersonal predictors of moving toward smoking cessation among YAs. Methods: Self-report data on 592 YA and 2777 older adult smokers were compiled from the Ontario Tobacco Survey baseline and six-month follow-up interviews. Smoking cessation behaviour was measured as an ordinal variable: made no attempt to quit, made a QA that lasted for less than 30 days, and successfully quit for 30 days or longer. Design-based analyses examined the characteristics of young and older adult smokers. Making a QA and smoking cessation during a six-month follow-up period were modeled according to the SCT constructs while accounting for the complex study design. Results: Young adult smokers were more likely to be men with lower levels of addiction but greater self-efficacy and an intention to quit than their older counterparts. While YA smokers were more likely to make a QA than their older counterparts (25% vs. 17%, respectively), they were no more likely to succeed (14% vs. 10%, respectively). Having an intention to quit smoking and having made two or more lifetime number of QAs predicted making a QA; the use of smoking cessation aids or resources and having knowledge that stop smoking medications make quitting a lot easier also contributed to making an attempt to quit. Self-efficacy, use of smoking cessation aids or resources and having someone to support one‘s QA were positive predictors of quitting whereas having high levels of addiction was a negative predictor of cessation. Conclusions: Young and older adults are distinct types of smokers with different personal and smoking characteristics. Different factors predicted making a QA and smoking cessation among YAs. Smoking cessation interventions for YAs should provide social support and skills to build and maintain self-efficacy to quit. It is critical to ensure YA smokers have effective smoking cessation aids and services that are easily accessible and appropriate for this population. Future research is needed to understand long-term smoking cessation and relapse in this vulnerable population.

Only a small number of studies dealing with burnout among coaches have been published, and none of these have dealt with burnout among elite soccer coaches in a European context. This thesis – investigating both the burnout and recovery process – includes a longitudinal design spanning ten years. Out of 53 head coaches, from elite soccer teams in Sweden, 47 participated in study 1. Results showed that burnout scores assessed by Maslachs Burnout Inventory (MBI) were generally low, but coaches in women’s premier league showed significantly higher levels of emotional exhaustion than coaches in men’s soccer teams. A sub-sample of these 47 coaches was interviewed for study 2, namely those 8 reporting the highest MBI scores. Characteristics of the elite coach professions personality traits and the allover life situation of the coach were identified as risk factors for developing burnout, as well as some retention factors, risking to create detention effects which might worsen the stress levels of the coach. In study 3 and 4, the burnout and recovery processes were examined, respectively. On the basis of descriptions from the coaches, three separate phases are discerned from the burnout process: a phase of restlessness and annoyance, a fatigue phase and finally a phase of exhaustion and burnout, while it is possible to make out four phases in the recovery process: a wake-up process, a phase removing one-self, a phase of reflection and evaluation, and finally a phase of new-orienting one-self. Study 5 revealed that both energy cost reducing strategies and energy boosting activities, were used by the coaches to prevent burnout. Study 6 showed that lack of sufficient recovery periods inhibited a lowering of the burnout levels, but also that lack of adequate coping strategies slowed the recovery process and also that coaches who have experienced burnout have an impaired professional efficiency. Finally, the focus in study 7 was on longterm consequences of burning out. Increased fatigue, diseases, cognitive impairment and a lower stress tolerance were examples of negative consequences, whereas an improved ability to identify stress causes and an enhanced awareness about one’s stress reactions, as well as to reflect and prioritize health, were examples of positive and favourable consequences. It is also urgent that elite clubs strive to create a good psycho-social work environment, which will function as a buffer against stress.

The economic wellbeing, physical and mental health of the ageing population in the United Kingdom is associated with continued participation in the labour force. Encouraging later life employment is therefore a key policy issue. Research into older person's employment trajectories is concentrated on male working patterns, and often takes an individualistic approach that does not account for the domestic context. Previous research on women's labour force participation has been informed by small scale qualitative studies that do consider the household domain but these findings cannot be generalized to the wider population. This research investigates the factors associated with the continued employment of women aged 50 to 59 using data from the English Longitudinal Study of Ageing (ELSA). Transition rates out of employment between 2001 and 2011 are modeled using multilevel discrete time event history specifications that permit the inclusion of time varying covariates. Retirement is characterized as an ageing process which allows the impact of predictors on transition rates to be assessed and measured as women approach state pension age. Alternative time structures are considered, with parameter estimates from an age baseline model compared with those from a time on study specification. Results illustrate the sensitivity of parameter estimates in discrete time event history models to the measurement of time, and emphasize the importance of adopting a time metric that is commensurate with the theoretical representation of retirement as a dynamic ageing process. The domestic context is realised as sampled women and their male partners are positionedwithin a household structure, and asymmetric effects of predictors on the transition rate of each gender are considered. Own poor health, caring responsibilities and a retired or inactive spouse accelerate labour market exit for women whilst high levels of accrued pension wealth predict earlier transitions for their male partners. The age of employment exit for females is independent of pension wealth, but pension resources do predict the retirement pathway taken following any transition that does occur. Women residing in the wealthiest households are more likely to report as voluntary retired prior to state pension age whilst those in the poorest of couples are at higher risk of following an involuntary pathway into an alternative inactive state. These findings emphasize the importance of conducting research into later life employment trajectories on a household, rather than individual, basis.

The objective of this study was to assess whether, and how, the attitudes towards business ethics of South African business students have changed between the early 1990s and 2010. The research was conducted as a cohort study utilising the same instrument, the Attitudes towards Business Ethics Questionnaire (ATBEQ). This study compared the results of the survey of the MBA alumni of the Gordon Institute of Business Science (GIBS), to the published results from a similar study at Rhodes University from the early 1990s. The study found a significant change in attitudes, with a trend towards stronger opinions, on business ethics and espoused values. A factor analysis of the responses showed eleven factors although it was less able to explain the variation in the attitudes than the previous study. A significant change in the rankings of variables also indicated a shift in priorities. These results indicated a shift towards a teleological moral philosophy as well as utilitarian motives. This shows a clear trend towards compliance-based ethics which can be explained by the proliferation of business legislation and regulation in the wake of recent corporate governance failures and the subsequent global financial crisis. / Dissertation (MBA)--University of Pretoria, 2010. / Gordon Institute of Business Science (GIBS) / unrestricted

Widespread critical shortages of high-quality teachers in the United States (Sutcher, Darling-Hammond, Carver-Thomas, 2016) has prompted considerable research on staffing trends within the teaching profession. Research suggests both an increase in the demand for teachers and a "chronic and relatively high annual turnover compared with many other occupations" (Ingersoll & Smith, 2003, p. 31). Recent studies have highlighted the negative effects that high teacher turnover has on financial costs, school climate, and student performance. Since attrition rates appear to be higher for beginning teachers (Ingersoll & Smith, 2003; Ingersoll, 2012), it is important to understand why beginning teacher attrition occurs and what factors influence beginning teachers to stay in the profession, move to another school, or return to the profession. While several studies suggest multiple factors influence teacher attrition, having a better understanding of how these factors correlate with each other and how the impact of these factors changes over time will provide additional information into how time influences teacher attrition. Exploring where teaching go after they leave teaching and why some teachers decide to return to the profession will provide additional insight into the complex nature of teacher attrition patterns in the United States. The purpose of this study was to examine attrition patterns among K-12 teachers who began teaching in a public school in the United States during the 2007-2008 academic year and factors that influenced teachers decisions to move from their initial school to another school, discontinue teaching, or return to the position of a K-12 teacher. This study used data collected as part of the Beginning Teacher Longitudinal Study (BTLS) and explores the effect that various predictor variables have on the probability that BTLS teachers will either leave teaching or move to another school. Using a structural equation modeling (SEM) approach to discrete-time survival analysis made it possible to simultaneously model systems of equations that included both latent and observed variables, allow for the effect of mediators, and analyze how the effect of each predictor variable changed over time. Results suggest the higher the teachers' base salary during their first three years of teaching, the less likely they were to leave the profession during their second through fourth years of teaching. Teachers who supplement their base salaries by working extra jobs are more likely to leave the profession after their fourth year of teaching. Teachers who participated in an induction program during their first year of teaching were less likely to leave the profession in Wave 2 of the study and teachers who had taken more courses on teaching methods and strategies before they started teaching were less likely to leave teaching in all waves of the study than teachers who had taken fewer courses on teaching methods or strategies. Teachers who reported higher levels of positive school climate during their first year of teaching were less likely to leave the profession in Wave 2 and 4. Teachers who indicated higher levels of satisfaction with being a teacher in their school were less likely to move schools than teachers with lower levels of satisfaction and teachers who taught in schools with higher percentages of students who were approved for free or reduced prices lunches were more likely to move schools than teachers with lower percentages of students who were approved for free or reduced price lunches. However, due to convergence issues, these results should be interpreted with caution. Weighted item response descriptive analyses suggest teachers' most important reason for moving schools was to work in a school more convenient to their home. Teachers who leave teaching are more likely to enter professions or occupations in education-related fields than occupations outside the field of education. Results also suggest teachers who leave the profession of teaching are more likely to be working in a job, either full-time or part-time, than not working in job. Finally, the majority of teachers who return to the profession of teaching do so because they missed being a K-12 teacher or they want to make a difference in the lives of others. This study contributes to the existing literature on teacher attrition by testing whether multiple relationships exist between various predictor variables and beginning teacher attrition and examines how the influence of each of these predictor variables changes over time. The study also investigates topics that have been relatively unexplored in the literature, including where teachers go when they leave the profession and factors that influence teachers' decisions to return to the profession. The results of this study may benefit researchers, teachers, educators, administrators, and policy makers interested in and/or studying teacher attrition in the United States.

Background. Little is known about longitudinal prescribing practices for psychoactive medications for individuals with intellectual disabilities and developmental disabilities (IDDD) who are living in community settings. Methods. Computerized pharmacy records were accessed for 2344 community-based individuals with IDDD for whom a total of 3421 prescriptions were written during a 17-month period of study. Forty-two psychoactive medications were rank ordered in terms of prescription frequency. Results. Fifty-two per cent (52%) of all prescriptions written during the study period were for psychoactive medications. Anticonvulsant, antipsychotic and antidepressant medications were the most commonly filled prescriptions among psychoactive medications. Sixty per cent (62%) of the study population was given prescriptions for more than one psychoactive medication and 36% received three or more psychoactive medications. During the study period there was a statistically significant increase in prescriptions filled for olanzapine, risperidone, valproic acid, and clonazepam whereas prescriptions filled for thioridazine, haloperidol, and benzotropine showed a significant decline (P < 0.05-0.001). Distribution of psychoactive drug class by age showed that the majority of prescriptions were filled for individuals between 20 and 50 years with the exception of prescriptions for psychostimulants which peaked for individuals prior to 20 years. Conclusions. (1) Analysis of pharmacy billing records provides a method for assessing prescribing patterns of psychoactive medications in community-based individuals with IDDD. (2) Polypharmacy for psychoactive medications is prevalent in this setting. (3) The second-generation antipsychotic medications are prominently represented by an increasing number of filled prescriptions during the study period.
