Simple as the outflow clock principle may seem for the measurement of time, its translation into an accurate clock raises formidable technical and conceptual problems. An attempt is made here to reconstruct the Egyptians' consciousness of these problems, and the success of their solutions. 相似文献

Research that clearly demonstrates the negative effects of institutionalization, particularly for young children, has been critical for changing policy. However, actually putting science into action requires advocacy, persistence, and perseverance. Policy makers and advocates must be informed about the research and use it effectively. This paper proposes a number of key components for translating research into policy and programs: analyzing the situation, using evidence to build the case for action, developing policies, building program capacity in child welfare and early childhood development, creating a family‐based child welfare system, and developing a system of monitoring and accountability. Much of the knowledge in this paper comes from experiences, desk reviews, and case studies of successful practices. Research provides the basis, but moving research to practice depends on collaboration between researchers who understand the key policy perspectives and policy makers who understand the research. 相似文献

Cultural values may be seen as the primary determinants of altitudes towards deviant or exceptional persons. The present study deals with the attitudes of Jewish and Arab youth in Israel towards the disabled as a function of cultural identity, existence of contact with a disabled person, and type of disability (blindness, amputation, facial disfigurement, or confinement to a wheelchair).A sample of 510 Jews and 655 Arabs filled out the Yuker Altitudes Towards Disabled Persons Scale (ATDP). The results indicated that overall, Jews were more positive towards the disabled than Arabs. Furthermore, the existence of previous contact with a disabled person was a positive factor in the formation of the Jews' attitudes, and a negative factor for the Arabs. In their ranking of different types of disability, Jews and Arabs differed significantly.The results are interpreted in the context of modern versus traditional cultures, whereby the Jewish youths' more tolerant Western approach seems to engender a more positive attitude than the Arab youths' conservative values. 相似文献

In latent growth modeling, measurement invariance across groups has received little attention. Considering that a group difference is commonly of interest in social science, a Monte Carlo study explored the performance of multigroup second-order latent growth modeling (MSLGM) in testing measurement invariance. True positive and false positive rates in detecting noninvariance across groups in addition to bias estimates of major MSLGM parameters were investigated. Simulation results support the suitability of MSLGM for measurement invariance testing when either forward or iterative likelihood ratio procedure is applied. 相似文献

We investigate the relationship between a firm’s compensation structure and the extent to which its innovation is more exploration versus exploitation oriented. Specifically, we assess two aspects of a firm’s compensation design—horizontal dispersion within job levels and vertical tournament incentives between job levels. A six-year panel of compensation records of 671,028 employees working at 81 U.S.-based high technology firms between 1997 and 2002 are used to construct measures that characterize a firm's pay structure, which are linked to these firms’ patents filed in the U.S. We find that firms with higher-powered tournament incentives in vertical compensation structure report higher fraction of innovation directed towards exploration. Horizontal pay dispersion, on the other hand, shows a negative relationship with the exploration in firms where R&D employees’ age variance is low. In firms where R&D employees’ age variance is high, the negative relationship between horizontal pay dispersion and exploration is muted. 相似文献
