We critique transformational leadership education in university business schools based on a literature review, a study of the websites of 21 leading business schools, and an analysis of two presentations to business school students at Massachusetts Institute of Technology and Stanford University by the former CEO of General Electric, Jack Welch. Our critique draws attention to the unresolved tension between two motivating ideas that underpin much teaching in business schools: collective interest ideas that permeate transformational leadership education; and self-interest ideas derived from agency theory. Transformational leadership tends to be depicted as a process by which leaders exert a 'top-down' influence over the activities of others, while simultaneously asserting that their organizations have a common purpose and pursue a collective interest. We highlight the risk that business schools are producing graduates who will attempt to appeal to common needs (guided by precepts of transformational leadership) but who will simultaneously enact contradictory performance management systems (guided by agency theory). We encourage business school educators in leadership to adopt approaches which are more critical, relational and reflexive. We suggest some general directions for an alternative leadership prospectus, based on followership, the promotion of critical upward communication within organizations, and the recognition of leadership as a contested, discursive and co-constructed phenomenon. 相似文献

AbstractObjective: To explore the relationship between symptoms of attention-deficit hyperactivity disorder (ADHD), symptoms of binge eating disorder, and body mass index (BMI) among students at a southern university. Participants: Two hundred seventy-seven college students. Methods: Between January 31, 2013 and March 27, 2013, participants completed the Adult ADHD Self-Report Scale (ASRS) Screener and the Binge Eating Scale (BES) in addition to permitting researchers to measure their height and weight. Results: Higher ASRS scores, higher BMIs, and lower BES scores were observed among men. Among both men and women, BES scores were positively correlated with BMI and ASRS scores; however, the correlation between ASRS and BMI was not significant. Conclusion: Binge eating disorder symptomatology was associated with increased ADHD symptomatology and a higher BMI among both men and women. Among students presenting with obesity or ADHD, screening for binge eating may assist with the identification of problematic eating behaviors. 相似文献

The purpose of this study was to systematically review the empirical literature on maternal bonding and associations with infant physical, psychological, and social development. Nineteen articles met inclusion criteria and were included in a qualitative synthesis (79 effect sizes); 15 articles were suitable for aggregation in a series of 14 meta‐analyses (51 effect sizes). All mean effects were in the expected direction, with higher maternal bonding contributing to infant developmental outcomes, including higher attachment quality (r = .35) and parent‐reported lower colic rating (r = .22), easier temperament (r = .19), and positive infant mood (r = .27). Consistent with theoretical explanatory models, the review provides support for the hypothesis that maternal bonding plays a role in fostering more optimal infant development. The review also identifies a paucity of empirical work on this topic and provides directions for future research. 相似文献

A detailed mathematical modeling framework for the risk of airborne infectious disease transmission in indoor spaces was developed to enable mathematical analysis of experiments conducted at the Airborne Infections Research (AIR) facility, eMalahleni, South Africa. A model was built using this framework to explore possible causes of why an experiment at the AIR facility did not produce expected results. The experiment was conducted at the AIR facility from August 31, 2015 to December 4, 2015, in which the efficacy of upper room germicidal ultraviolet (GUV) irradiation as an environmental control was tested. However, the experiment did not produce the expected outcome of having fewer infections in the test animal room than the control room. The simulation results indicate that dynamic effects, caused by switching the GUV lights, power outages, or introduction of new patients, did not result in the unexpected outcomes. However, a sensitivity analysis highlights that significant uncertainty exists with risk of transmission predictions based on current measurement practices, due to the reliance on large viable literature ranges for parameters. 相似文献

This study examined how open communication between spouses may buffer against discrimination experienced by Black–White couples. Results from 178 couples analyzed using a combination of common‐fate and actor–partner interdependence models, indicated that for Black partners, marital satisfaction was not contingent on the level of openness when experiences of couple discrimination were low. When experiences of couple discrimination were high, levels of marital satisfaction were maintained among partners who reported high openness and reduced among partners who reported low openness. Moderation effects were not found for White partners. The results suggest that because Black partners are more aware of and sensitized to discrimination, White partners’ abilities to attune to their partners’ needs for support could help enhance their relationships. 相似文献

ABSTRACTVery little is known about how people perceive and respond to sexual relationships between students and teachers, and even less is known about how adolescents view these relationships. In this study, a large sample of high school students (N = 1203; Mean age: 16.83) responded to four scenarios describing a sexual relationship between a student and teacher. We manipulated student and teacher age, and the power differential between the student and teacher and we measured perceptions of wrongness and likelihood of reporting the situation. The data indicated that in situations of older students (18 vs. 14 or 16) and younger teachers (21 vs 30 or 40), they are less likely to be perceived as wrong and less likely to be reported. Likewise, situations were judged as more wrong when the power differential between students and teachers was greater. Further, there were strong gender differences, such that females (vs. males) consistently viewed the situations as more wrong and were more likely to report. Implications for future research and policy are discussed. 相似文献

This study compared advice that three groups—military parents, partners, and Veterans—gave regarding how military families can encourage service members (SMs) to seek professional help when needed. Based on identity implications theory and the normative model of social support, common themes regarding how families might pursue task, relational, and identity goals were expected (RQ1). Based on their unique positions, we investigated whether the three groups stressed different themes (RQ2). Military parents (n = 51), partners (n = 74), and Veterans (n = 112) read a scenario in which a SM was having difficulty reintegrating after deployment; all three groups offered advice about how military families should handle similar situations. Common themes regarding task, relational, and identity goals emerged in the advice from all three groups; however, parents, partners, and Veterans also differed significantly in how often they mentioned six themes. Theoretical and practical implications are discussed. 相似文献

Scholars have called for a better understanding of the performance consequences of individual ambidexterity. In this work, we utilize the context of academic entrepreneurship to study how and why individual ambidexterity impacts academic entrepreneurship performance, and whether relational context moderates this link. Alongside the benefits, we argue that higher levels of individual ambidexterity generate switching, coordination and cognitive costs that can harm performance. Acknowledging the simultaneous presence of varying costs and benefits over the range of individual ambidexterity, we propose that individual ambidexterity has an inverted U-shaped relationship with academic entrepreneurship performance, in which moderate levels produce superior performance. We further argue that relational context enhances the performance benefits of individual ambidexterity through providing access to novel knowledge and resources. In doing so, it shifts the turning point so that a higher level of individual ambidexterity produces peak academic entrepreneurship performance before the relationship turns. Utilizing data on Taiwanese scientists, we find strong evidence of an inverted U-shaped relationship between individual ambidexterity and academic entrepreneurship performance, and for the moderating role of relational context. 相似文献
