To explore Daft's dual-core model of educational organization, this study compares the managerial behavior of academic department chairpersons and nonacademic unit managers across 140 colleges and universities. For the study, 6,357 faculty and administrators completed questionnaires that profiled their formal leader's behavior, their work group characteristics, and their personal satisfaction. Of 54 variables submitted to discriminant analysis, 31 discriminated the bureaucratic units from the academic groups. Managers of the two types of group behave differently in ways consistent with their distinct group tasks. The empirically derived role profiles of the academic and nonacademic managers are discussed, as are the implications of the findings for institutional researchers, change agents, and trainers of college managers.This article is based in part upon a paper presented at the Seventh Annual European AIR Forum, Copenhagen, Denmark, 1985.  相似文献

OBJECTIVES: To examine the prevalence of bullying behavior in adolescents from Cape Town and Durban, South Africa, and the association of these behaviors with levels of violence and risk behavior. METHOD: Five thousand and seventy-four adolescent schoolchildren in grade 8 (mean age 14.2 years) and grade 11 (mean age 17.4 years) at 72 Government schools in Cape Town and Durban, South Africa completed self-report questionnaires on participation in bullying, violent, anti-social and risk behaviors. RESULTS: Over a third (36.3%) of students were involved in bullying behavior, 8.2% as bullies, 19.3% as victims and 8.7% as bully-victims (those that are both bullied and bully others). Male students were most at risk of both perpetration and victimization, with younger boys more vulnerable to victimization. Violent and anti-social behaviors were increased in bullies, victims and bully-victims compared to controls not involved in any bullying behavior (p<.01 in all cases). Risk taking behavior was elevated for bullies and bully-victims, but for victims was largely comparable to controls. Victims were less likely to smoke than controls (odds ratio .83, p<.05). Bully-victims showed largely comparable violent, anti-social and risk taking behavior profiles to bullies. Bully-victims showed comparable suicidal ideation and smoking profiles to victims. CONCLUSIONS: Results were in keeping with Western findings. Involvement in bullying is a common problem for young South Africans. Bullying behavior can act as an indicator of violent, anti-social and risk-taking behaviors.  相似文献

Multi-academy trusts (MATs) are now a common feature of the English educational landscape. Yet numerous high-profile failures indicate that they present substantial challenges in terms of leadership and governance. One of the areas that most exercises school leaders and boards is the setting of strategic direction for the MAT. This includes elements such as its expansion. This article draws on 30 interviews with school leaders and trustees from 6 MATs and 10 interviews with national leaders of governance in looking to respond to the research question: What are the principal drivers for strategic expansion in MATs? The article begins by contextualising the research in light of recent policy, then moves to consider why theory on strategy as narrative was chosen in preference to other strategic approaches, and how it was employed to analyse data. The article concludes that within this sample there are a number of drivers for MAT expansion and that these fall under six principal categories: opportunities, values, pressures, feelings, risks and resources. It also concludes that resources and business viability play a substantial part in decisions to expand, and that strategy appears to be an iterative learning process. As such, it contributes to theory on the governance of multi-level organisations and to practice in terms of the Department for Education's focus on MAT growth.  相似文献

The purpose of this study was to estimate the optimal body size, limb-segment length, girth or breadth ratios for 100-m backstroke mean speed performance in young swimmers. Sixty-three young swimmers (boys [n = 30; age: 13.98 ± 0.58 years]; girls [n = 33; age: 13.02 ± 1.20 years]) participated in this study. To identify the optimal body size and body composition components associated with 100-m backstroke speed performance, we adopted a multiplicative allometric log-linear regression model, which was refined using backward elimination. The multiplicative allometric model exploring the association between 100-m backstroke mean speed performance and the different somatic measurements estimated that biological age, sitting height, leg length for the lower-limbs, and two girths (forearm and arm relaxed girth) are the key predictors. Stature and body mass did not contribute to the model, suggesting that the advantage of longer levers was limb-specific rather than a general whole-body advantage. In fact, it is only by adopting multiplicative allometric models that the abovementioned ratios could have been derived. These findings highlighted the importance of considering somatic characteristics of young backstroke swimmers and can help swimming coaches to classify their swimmers and enable them to suggest what might be the swimmers’ most appropriate stroke (talent identification).  相似文献

In this study, we investigated what drives players to endorse an aggressive style in Swiss ice hockey and football. We selected a sample of 16 players on the basis of their penalty statistics. We used semi-directed retrospective interviews to collect players’; biographic narratives. The results show a socialization process into an aggressive style, supported by the dominant gender and socialization norms of the sport, which is under the influence of the structure of the sports organization. However, there are large differences between players, with only some of them adopting an aggressive style. Although many studies have underlined the influence of moral disengagement, the present results suggest that time also matters and that the diversity of career paths may explain the diversity in attitudes. Socialization differences in the sports field, bodily capital, a career path marked by thwarted reputation are the key factors that drive players to adopt an aggressive style.  相似文献
