Leadership and the fate of organizations   总被引:4,自引:0,他引:4  
This article concerns the real-world importance of leadership for the success or failure of organizations and social institutions. The authors propose conceptualizing leadership and evaluating leaders in terms of the performance of the team or organization for which they are responsible. The authors next offer a taxonomy of the dependent variables used as criteria in leadership studies. A review of research using this taxonomy suggests that the vast empirical literature on leadership may tell us more about the success of individual managerial careers than the success of these people in leading groups, teams, and organizations. The authors then summarize the evidence showing that leaders do indeed affect the performance of organizations--for better or for worse--and conclude by describing the mechanisms through which they do so.  相似文献

The current study investigated whether deficits in mindfulness (the awareness, attention, and acceptance of the present moment) can account for variability in borderline personality (BPD) features and characteristic difficulties in emotion regulation, interpersonal effectiveness, and impulsivity. Structural equation modeling and hierarchical regressions were utilized to examine the associations of trait mindfulness with BPD features, interpersonal problem-solving, impulsive and passive emotion-regulation strategies, and neuroticism in a sample of young adults (N = 342). As hypothesized, mindfulness was related inversely to BPD features and core areas of difficulty, and these associations continued even when controlling for neuroticism. Additionally, mindfulness deficits continued to predict borderline features even when interpersonal effectiveness, passive and impulsive emotion-regulation, and neuroticism were controlled. It is concluded that deficits in mindfulness may be integral to BPD features. Difficulties with attention, awareness, and acceptance of internal and external experience appear to explain borderline pathology even when controlling for problems with negative affectivity, behavioral dyscontrol, and emotional and interpersonal dysfunction--which have been described as definitional of this disorder. Thus, attention to mindfulness deficits may enhance clinical formulation of BPD symptomatology, as well as provide a vital component of effective BPD treatment.  相似文献

Profile Analysis via Multidimensional Scaling (PAMS) is a procedure for extracting latent core profiles in a multitest data set. The PAMS procedure offers several advantages compared with other profile analysis procedures. Most notably, PAMS estimates individual profile weights that reflect the degree to which an individual's observed profile approximates the shape and scatter of latent core profiles. The PAMS procedure was applied to index scores of nonreplicated participants from the standardization sample (N = 1,033) for the Wechsler Memory Scale--Third Edition (D. Tulsky, J. Zhu, & M. F. Ledbetter, 2002). PAMS extracted discrepant visual memory and auditory memory versus working memory core profiles for the complete 16- to 89-year-old sample and discrepant working memory and auditory memory versus working memory core profiles for the 75- to 89-year-old cohort. Implications for use of PAMS in future research are discussed.  相似文献

This study was designed to determine whether distinct subgroups of children with recurrent abdominal pain (RAP) could be identified based on patterns of psychological functioning. Two hundred and eighty-three children (ages 8–17 years), and a primary caretaker, completed the Behavior Assessment System for Children (BASC) during the initial evaluation of RAP at a pediatric gastroenterology clinic. Cluster analysis of BASC scores supported a 3-cluster solution, with fair agreement observed between parents and children on cluster assignment. Approximately half of the sample identified no significant psychological problems. A small percentage (13%) evidenced intense and broad-based psychological problems, while the remainder (35–45%) indicated relative elevations in anxiety only. Cluster membership did not vary systematically by age, gender, race, or functional gastrointestinal disorder diagnosis. Distinct psychological profiles appear to exist for children with RAP. Targeting treatments to these profiles may improve the effectiveness and efficiency with which health professionals address pediatric abdominal pain. This study was supported in part by a grant from the Hall Family Foundation. Portions of this work were presented at the annual convention of the American Psychological Association in July 2004 (Honolulu, HI) and at Digestive Diseases Week in May 2004 (New Orleans, LA).  相似文献

Public debate on nanotechnology is a large topic within governments, research agencies, industry and non-government organisations. But depending who you talk to the perception of what the public thinks about nanotechnology can be very varied. To define coherent policy and to invest in research and development that aligns with public preferences, needs more than just perceptions of public perceptions. Public attitude studies are vital in understanding what the public really think, but they need to go further than simplistic polling and should examine factors such as changes over time, drivers of attitude change, different attitudes to different applications and be supported by qualitative data. This paper summarises the findings of a three year tracking study of public attitudes towards nanotechnology, highlighting both concerns and aspirations for nanotechnology and discusses the impacts of that data on public engagement programs.  相似文献

Over the last decade, researchers have debated whether anchoring effects are the result of semantic or numeric priming. The present study tested both hypotheses. In four experiments involving a sensory detection task, participants first made a relative confidence judgment by deciding whether they were more or less confident than an anchor value in the correctness of their decision. Subsequently, they expressed an absolute level of confidence. In two of these experiments, the relative confidence anchor values represented the midpoints between the absolute confidence scale values, which were either explicitly numeric or semantic, nonnumeric representations of magnitude. In two other experiments, the anchor values were drawn from a scale modally different from that used to express the absolute confidence (i.e., nonnumeric and numeric, respectively, or vice versa). Regardless of the nature of the anchors, the mean confidence ratings revealed anchoring effects only when the relative and absolute confidence values were drawn from identical scales. Together, the results of these four experiments limit the conditions under which both numeric and semantic priming would be expected to lead to anchoring effects.  相似文献

ABSTRACT— Two studies tested the hypothesis that exposure to violent media reduces aid offered to people in pain. In Study 1, participants played a violent or nonviolent video game for 20 min. After game play, while completing a lengthy questionnaire, they heard a loud fight, in which one person was injured, outside the lab. Participants who played violent games took longer to help the injured victim, rated the fight as less serious, and were less likely to "hear" the fight in comparison to participants who played nonviolent games. In Study 2, violent- and nonviolent-movie attendees witnessed a young woman with an injured ankle struggle to pick up her crutches outside the theater either before or after the movie. Participants who had just watched a violent movie took longer to help than participants in the other three conditions. The findings from both studies suggest that violent media make people numb to the pain and suffering of others.  相似文献
