Organizational values of people and respect and interdependent structures of team procedures and task interdependence may help departments believe their goals are cooperative and thereby coordinate effectively. CEOs in China completed measures of their organization’s values and interdependent structures and their Vice-Presidents completed measures of the department’s goal interdependence (cooperative, competitive, and independent) and collaborative effectiveness. Structural equation analysis suggested that values and interdependent structures promote cooperative, but not competitive or independent, goals that in turn results in collaborative effectiveness. These results, coupled with previous research, were interpreted as suggesting that people and respect values, team procedures, task interdependence, and cooperative goals are complementary foundations for synergy in China and perhaps other countries as well.

Schlafst?rungen erkennen und behandeln — Erholsamer Schlaf ist die Grundvoraussetzung für k?rperliche und geistige Leistungsf?higkeit. Doch für viele Menschen ist das Ein- und Durchschlafen ein n?chtlich wiederkehrender Kampf. Auch bei den Bewohnern von Pflegeeinrichtungen sind Schlafst?rungen verbreitet. Mitunter k?nnen aber bereits einfache, gezielte Ma?nahmen den Schlaf wieder stabilisieren.  相似文献

Publication in the best journals of ones discipline is for many the equivalent of making the big leagues in sports or performing at Carnegie Hall in the arts. Using individual-specific data collected from 704 economists, this study provides a multivariate analysis of the factors which contribute to publication in top economics journals. By examining only publications in elite journals, the analysis avoids pitfalls associated with weighting the quality of a wide array of journals while maintaining an emphasis on the determinants of excellence in scholarship. Empirical results indicate that many factors impact elite journal publication, including the quality of graduate education, collaboration with colleagues, presenting at professional conferences, teaching commitments, and service work.  相似文献

Der vorliegende Beitrag fragt nach der demographischen Struktur der zentralen akademischen Akteure der Kommunikationswissenschaft in Deutschland und nach m?glichen Ver?nderungen dieser Struktur in den letzten 50 Jahren. Die Analyse zeigt zum einen, dass von einem einheitlichen Zugang zum Hochschullehrerberuf nach wie vor keine Rede sein kann, und zum anderen, dass das Fach vor einer demographischen Herausforderung steht. Die Kommunikationswissenschaft hat sich durch Akademisierung und ?Versozialwissenschaftlichung? von ihren Wurzeln gel?st. War Berufserfahrung im Medienbereich bis in die 1960er Jahre Voraussetzung für eine Berufung, verfügt heute nur noch eine Minderheit über solche Erfahrungen. Da die Existenz des Faches im Rahmen der Universit?t auch von der Nachfrage der Studierenden abh?ngt, kann man über die Folgen des anstehenden Generationswechsels nur spekulieren. In jedem Fall fehlt es an formal für die Hochschullehrerlaufbahn qualifiziertem Nachwuchs. Deshalb sind erhebliche Anstrengungen erforderlich, wenn der Boom im letzten Drittel des 20. Jahrhunderts sich nicht als Seifenblase erweisen soll.  相似文献

Affection in learning embraces emotions, attitudes, values and beliefs that emerge during the learning process, and it is a vital and hidden element of learning. Studies focusing on affective, or emotional, aspects of design learning in the context of design education underscore the significance of the affective process and inform us of the connection between the creative dimension and emotions during a design activity. To this point, this paper addresses the following research question: to what extent does reflective writing disclose design students’ affective journeys throughout a semester? An empirical study is conducted to observe first-year industrial design students’ affective processes during a semester using their structured reflective diaries. The longitudinal study results show that the students exhibit certain tendencies in terms of the affective processes throughout a semester. The findings of this study are discussed in reference to peak points, anomalies and tendencies of the affective processes observed based on excerpts from the diaries. It is concluded that affective responses in design learning are multidimensional and wide-ranging.  相似文献

Using a sample of Chinese listed firms in the period from 2003 to 2012, this paper empirically investigates how the presence of politically connected directors affects stock price crash risk. We thereby make a distinction between listed state-controlled firms and privately controlled firms due to their different incentives to appoint politicians as directors on the board. Our empirical results show that politically connected directors exacerbate stock price crash risk in listed state-controlled firms, an effect driven by the appointment of local government officials as directors. In contrast, hiring politicians as directors, particularly central-government-affiliated directors, helps listed privately controlled firms to reduce stock price crash risk. Finally, good quality of institutions does not help to alleviate the positive relationship between political connections and stock price crash risk in listed state-controlled firms. However, it does weaken the role of political connections in reducing crash risk in listed privately controlled firms.  相似文献

Access to specialists for treatment of behavioral health problems has become restricted in this era of capped budgets and reductions in Medicare and Medicaid reimbursement. Patients with multiple mental health problems may face additional barriers to obtaining needed health care services. The study's aim was to measure the impact of behavioral health problems on access to care and health services utilization for veterans and non-veterans and to determine the contribution of health system characteristics in the prediction of self-reported health services utilization. The study sample consisted of Vietnam veterans who participated in both the Vietnam Drug User Study (September 1971 Army discharges) and the Vietnam Era Study (25-year follow-up) (N=642), as well as a non-veteran cohort (N=197).  相似文献
