This study examined the influences of generational status, self‐esteem, academic self‐efficacy, and perceived social support on 367 undergraduate college students' well‐being. Findings showed that 1st‐generation students reported significantly more somatic symptoms and lower levels of academic self‐efficacy than did non‐1st‐generation students. In addition, students' generational status was found to moderate predictive effects of perceived family support on stress. Implications for professional practices, limitations, and directions for future research are discussed. 相似文献

IT project portfolio management (IT PPM) has evolved into a significant area of research interest, but we know little about IT PPM practices in public sector organizations. Therefore this article investigates decision-making processes in the IT PPM practices of local governments, and discusses how these practices match the normative advice proposed by the IT PPM literature. We rely on decision-making theories together with case-studies of four Danish local governments. We find that politics, intuition and coincidence play a crucial role in IT PPM decision-making, while technical rationality (as proposed by the IT PPM literature) plays a minor role. Our account also reveals how the decision-making practices create IT portfolio problems and in some aspects is considered to have a negative impact on the outcome of e-government investments. Our analysis and previous research into decision-making allows us to argue that implementing textbook-IT PPM is difficult because it relies on decision-making ideals that are incompatible with organizational contexts and individual behavior in these organizations. Instead of radically changing decision-making styles, the organizations might be better off improving IT PPM practice within the boundaries of their existing decision-making styles, and the IT PPM literature might improve support for practitioners by incorporating other decision-making styles besides technical rationality. 相似文献

Using a variety of programmed materials, this series of studies showed that students observed available answers in the program far less than 100% of the time. Answer observing was found to be correlated with student error on the related frame. The view that the printed answer in a program is always a reinforcer for the preceding response(s) is severely questioned. 相似文献
