Despite the high ‘guru‐factor’ in time management, few claims have been subjected to empirical investigation. This study tests the claims that people who manage their time well perceive themselves to be more effective and feel less stressed. University staff and students were utilized to investigate the relationship between time management related behaviours, perceived effectiveness, and work‐related morale and distress. Results suggested a hierarchy of time management behaviours. Having a clear sense of career purpose was most important for perceived effectiveness at work, followed by planning and prioritizing. This study has significant practical implications for staff and students. If the aim of using time management strategies is to improve performance and reduce stress, people need to learn to identify the purpose in their career, then plan their time accordingly, rather than tidying desks and hanging ‘do not disturb’ signs on doors.  相似文献

Research findings on class size differences need to be examined carefully because of their far reaching pedagogical and resource implications. An examination of research on the possible causal effect of class size differences on pupil progress, and on possible mediating factors, also raises important issues for educational research in general. In this chapter critically different approaches to research on class size effects are reviewed and an approach used in current research at the Institute of Education, that seems most likely to inform this controversial topic is described. Researchers need to pay more attention to providing a more reliable and valid measure of class size itself. In keeping with the bulk of research in this area the emphasis is on quantitative approaches, although possible limitations and alternative research approaches are considered. Limitations of earlier cross sectional research are examined, and the well-known STAR research is used to highlight some limitations of experimental designs. Finally, the advantages of longitudinal research, using multi-level modelling techniques, are examined.  相似文献

The form, content, and practice of history has shifted including changes in conceptualization and practice that came in viewing history as social science, critiques and reconstructions of historical forms of knowledge, and debates about form, format, genre, and discourse. The central argument of this essay begins with the claim that history is a distinctive discipline. It's distinction lies not only, or even primarily, in its subject matter or materials. Rather, history is distinct as a form of inquiry and mode of understanding, with distinguishing characteristics of historical context and historical imagination. Important implications follow.  相似文献

Conduct Disorder (CD) research is focusing on complex issues introduced by comorbidity because of its widespread existence, thoeretical importance and practical significance. This review provides critical examination of research published during the past ten years addressing CD and its comorbid conditions, specifically Attention‐Deficit Hyperactivity Disorder (ADHD), Oppositional Defiant Disorder (ODD), and internalizing disorders. It is concluded that comorbidity varies with age, gender, informant, diagnostic criteria, and nature of the sample (clinical vs. epidemiological). Implications of comorbidity for etiology, diagnosis, treatment, law, and policy and preventive efforts in work with children and adolescents with CD are offered for school psychologists. © 1999 John Wiley & Sons, Inc.  相似文献

This article responds to the other 10 papers in this thematic issue on science and worldviews and it clarifies some of the points in my lead article. The Bayesian framework provides helpful structure for worldview inquiries by recognizing and integrating both public and personal evidence. Drawing upon the other 10 papers, six kinds of potential evidence or considerations are identified: the problem of evil, evolution, miracles and prayer, the Anthropic Principle, religious experience, and natural theology. The thesis is defended that considerations informing worldview convictions include public evidence from the sciences and the humanities and personal evidence from individual experience. Additional topics addressed briefly include scientific realism, the tentativeness of scientific knowledge, science’s presuppositions, the relationship between natural science and natural theology, the nature of religious faith, and the importance of philosophy in science education. Seven questions are posed for which further leadership from the AAAS and NAS would benefit the scientific community.  相似文献
