Fed up with skyrocketing health insurance costs, poor quality care and low patient satisfaction, a group of powerful benefits executives from some of the country's largest employers decided to do something about it. They formed The Leapfrog Group, a coalition of companies setting out to build a better American health care system. 相似文献

Dimensions of Risk Perception for Financial and Health Risks 总被引:1,自引:0,他引:1
This study of 29 MBA students compares two models of risk perception for both financial and health risk stimuli. The first, inspired by Luce and Weber's Conjoint Expected Risk (CER) model, uses five dimensions: probability of gain, loss and status quo, and expected benefit and harm. The second, inspired by the Sovic et al. psychometric model, employs seven dimensions: voluntariness, dread, control, knowledge, catastrophic potential, novelty, and equity. The CER-type model provided a better fit for most subjects and stimuli. Adding the psychological risk dimensions from the Slovic et al. model explained only modestly more variance. Relationships between the dimensions of the two models are described and the construction of a hybrid model explored. 相似文献

In spite of calls for deliberate differentiation between individual and team levels of analysis, leadership research based on well-grounded theory referring to multiple levels is scarce. We seek to fill this gap by analyzing the relations between transformational leadership, trust in supervisor and team, job satisfaction, and team performance via multilevel analysis. Results are based on a sample of 360 employees from 39 academic teams. Transformational leadership was positively related to followers' job satisfaction at individual as well as team levels of analysis and to objective team performance. The relation between individual perceptions of supervisors' transformational leadership and job satisfaction was mediated by trust in the supervisor as well as trust in the team. Yet, trust in the team did not mediate the relationship between team perceptions of supervisors' transformational leadership and team performance. Implications for theory and research of leadership at multiple levels as well as for practice are discussed. 相似文献

In response to calls for context-specificity in leadership research, we developed and validated a Situational Judgment Test of the Full Range of Leadership Model (SJT-FRLM). Three consecutive studies were conducted following the typical steps of test development. Study 1 served measure development and pilot testing: item stems were generated empirically, item responses were developed with a theory-driven approach, and pilot testing was based on a leader sample. Study 2 served to analyze construct- and criterion-related validity of the instrument. Moreover, an empirical scoring key was developed that weights each item response according to its relation with leadership effectiveness in each situation. In Study 3, we demonstrated incremental validity and interrater agreement. The test fills an important gap in literature because it not only has predictive validity above and beyond established measures, but also takes into account the contextual element of leadership. 相似文献

The successful foundation of entrepreneurial firms comprises a multitude of complementary human tasks. The effect of founders’ human capital on firm success hinges on the information structure that prevails when nascent entrepreneurs are matched in partnerships. Empirically, we assume that rational matching occurs in incubated spin-offs and corporate-sponsored ventures. The human capital structure in such firms significantly differs from that of Greenfield projects. Using coarsened exact matching (CEM), we compute weights to level out these differences in human capital endowments. The impact of corporate support in founding the new firm is positive and increases as CEM-weights are applied to more of our human capital variables. 相似文献

Summary One of the most salient data problems empirical researchers face is the lack of informative responses in survey data. This
contribution briefly surveys the literature on item nonresponse behavior and its determinants before it describes four approaches
to address item nonresponse problems: Casewise deletion of observations, weighting, imputation, and model-based procedures.
We describe the basic approaches, their strengths and weaknesses and illustrate some of their effects using a simulation study.
The paper concludes with some recommendations for the applied researcher.
We are grateful to an anonymous referee who provided helpful comments. Also we like to thank Donald B. Rubin for helpful comments
and always motivating discussions as well as Ralf Münnich for inspiring discussions about raking procedures. 相似文献

Zusammenfassung Personalentwicklungs-und Coachingprozesse müssen und sollten sich nicht auf hergebrachte Lehrer-Lerner-Modelle begrenzen.
In vielf?ltigen Lernkontexten und insbesondere in der Didaktik haben reziprok angelegte Lernpartnerschaften zwischen zwei
Personen auf Zeit lange Tradition. Zentrale Erwartungen richten sich in der Regel einerseits auf die ?konomie entsprechender
Settings, andererseits auf die Nachhaltigkeit und Ganzheitlichkeit einer Unterstützung, die im Medium ?hnlicher Position,
?hnlicher Erfahrung und der Gegenseitigkeit der Supportbeziehung entsteht. Diese Erwartungsbündel gelten als Unterscheidungskriterien
gegenüber expertengestützten Lehrer-Lerner-Modellen.
Im folgenden wird das Konzept einer Lernpartnerschaft auf Gegenseitigkeit im Kontext der Führungskr?fteentwicklung er?rtert.
Nachdem seit einiger Zeit „Tandem“-Ans?tze im Profit-Bereich in ersten Projekten erprobt werden,1 geht es in diesem Beitrag nicht zuletzt um überlegungen, die sich auf die Eignung für den Bereich der Non-Profit-Organisationen
(NPO; vgl. als überblick Badelt, 2002) sozialer Dienstleistungen beziehen, da eine übertragbarkeit angesichts der historischen
und systematischen Spezifika im NPO-Bereich nicht umstandslos gegeben sein muss. Wirkungen werden wesentlich im Referenzrahmen
sozialer Unterstützung thematisiert, der in besonderem Ma?e geeignet scheint, die auf Austauschprozessen beruhenden Effekte
zu begreifen.

As the recent OECD PISA studies have shown, social background plays a greater role for achieving a solid education in Germany
than in most other developed countries; this is especially so for migrant youths. This paper deals with the question, which
level education and qualification migrants in Germany achieve, and how their chances for achieving qualifications and positions
are compared to Germans. First, an overview over results of studies on educational participation, degrees, and social inequality
among migrants is given. Then I show, using data from the 2000 BiB-Integration Survey, that young Turks and Italians have
achieved notably lower levels of education than Germans. Finally, I discuss possible reasons and agencies that might cause
these findings, which then are scrutinised by empirical analyses. It can be found that the marked under-representation with
regard to higher educational and professional degrees of young Italians and Turks is clearly related to the low educational
level of their parents, as well as factors of integration and attitudes. It does become obvious, however, that Turks have
lower chances that cannot be explained by their parents’ qualification or other factors. This is also the case for the second
immigrant generation. 相似文献
