Does race affect the route to downward mobility from white collar occupations? Data from Panel Study of Income Dynamics are used to assess the minority vulnerability thesis, which maintains there are race-specific processes of down ward occupational mobility among males from white collar occupations. Findings indicate that, consistent with theory, a racialized continuum exists across six years of the work-career. For Whites, the path to downward mobility is relatively narrow and structured by traditional stratification-based causal factors, namely, human capital, back ground socioeconomic status, and job/labor market characteristics. For African Americans, the route to downward mobility is broad-based and not captured by traditional stratification factors and Latinos occupy an intermediate ground between Whites and African Americans. Further, as predicted by theory, the racial gap in mobility processes between Whites and racial minorities is pronounced at the lower-tier of white collar employment. Finally, implications of the findings for understanding labor market inequalities on the basis of race are discussed. 相似文献

中国的现代行政法与中国古代法律传统没有多大的延续性。相比较而言,英国行政法有着其引以为荣的绵延数世纪的历史,其重心在于对行政行为的司法审查。中国行政法的结构与英国行政法的结构截然不同。在中国的行政诉讼制度中,就司法审查的范围而言:首先,抽象行政行为不受司法审查;其次,内部行政行为不受司法审查;再者,《行政诉讼法》只授权对某些类型的具体行政行为案件进行司法审查。就行政行为的审查理由或标准而言,中国法律的有关规定要比英国或香港的较为有限。但就一方面而言,中国法律提供的审查空间和力度似乎比英国或香港更为宽泛,这便是对行政行为的事实依据的审查。 相似文献

This paper is an assessment of the impact of child support enforcement and welfare policies on nonmarital teenage childbearing
and motherhood. We derive four hypotheses about the effects of policies on nonmarital teenage childbearing and motherhood.
We propose that teenage motherhood and school enrollment are joint decisions for teenage girls. Based on individual trajectories
during ages 12–19, our analysis uses an event history model for nonmarital teenage childbearing and a dynamic model of motherhood
that is jointly determined with school enrollment. We find some evidence that child support policies indirectly reduce teen
motherhood by increasing the probability of school enrollment, which, in turn, reduces the probability of teen motherhood.
This finding suggests that welfare offices may wish to place greater weight on outreach programs that inform more teenagers
of the existence of strong child support enforcement measures. Such programs might reduce nonmarital teen motherhood further
and thus reduce the need for welfare support and child support enforcement in the long run.

Measurement of non-randomness in spatial distributions 总被引:4,自引:0,他引:4
Roger H. Green 《Researches on Population Ecology》1966,8(1):1-7
Summary The measurement of departure from randomness in spatial distributions has widespread application in ecological work. Several
“indices of non-randomness” are compared with regard to their dependence on sample number, sample size and density. Criteria
for the best choice of index for specific situations are discussed. A new coefficientC
x is proposed for use with positively contagious distributions and tests of significance are given. WhenC
x and another index (S
2/m−1) are used for positive and negative contagion respectively, values ranging from −1 through 0 (random) to +1 are obtained,
regardless of sample number, sample size or density. 相似文献

Two within household telephone sampling techniques for collecting citizen survey data for community mental health center's needs assessments were compared on the basis of respondent demographic characteristics; response, completion, and refusal rates; and, administrative costs. Initially, all households were chosen via random digit dialing. Then, one technique allowed the surveyor to interview any adult member of a household who answered the phone. The other technique used was developed by Troldahl and Carter and required the use of a reference table procedure to determine the appropriate respondent. While more expensive, the Troldahl-Carter method produced significantly better representativeness of the population for a rural county. Factors relating to a decision regarding which technique to employ are discussed. 相似文献

基督教流动人口是基督教在全球传播过程中的关键因素。在基督教存在的前五个世纪,广泛的人口流动将基督教变成了全球化的信仰。广泛的人口流动在其它主要的世界宗教在世界各地的传播过程中也发挥了重要作用,但是,就基督教来说,流动可能是这种信仰固有的因素。基督教超越罗马帝国成为全球性信仰是个非常复杂的过程,包含许多不同类型的人口流动。跨国界的领袖们、俘虏、难民和流浪者、商人是人口流动的四种主要类型。虽然,东部教会传教的成功是短暂的,但是东部教会在第一个千年形成的移民传教模式无疑为21世纪的基督教提供了典范。基督教在过去的两三个世纪里再次全球化,基督信仰作为新的中心在非洲、拉丁美洲和亚洲的某些地区出现,表明"人口流动"在基督教全球传播过程中的作用比以前更加明显。当代基督教的全球化与早期基督教的全球化在发展道路上有很大不同,但有一点是不变的,即基督教的全球化仍将主要依靠流动者的行动和决策。 相似文献

Examining Facilitative Configurations of Entrepreneurially Oriented Growth: An Information Processing Perspective 下载免费PDF全文
This study examines how the relationship between entrepreneurial orientation and firm growth is shaped by learning orientation in technologically sophisticated environments. We draw upon an information processing perspective that emphasizes alignment between information processing demands and support mechanisms. Using data from 116 small to medium‐sized enterprises in the Netherlands, we observe that the ability of entrepreneurial orientation to drive firm growth greatly depends on the joint consideration of technological sophistication and learning orientation. Our findings contribute to a better understanding of how configurations of strategic orientations and environmental considerations work in concert to influence the efficacy of organizational entrepreneurial efforts dramatically. 相似文献

From a motivational perspective of feedback-seeking behavior, we examined the mediating role of leaders' negative feedback-seeking from subordinates in the relationship between the quality of leader-member exchange (LMX) and subordinates' evaluation of leader effectiveness, along with the moderating role of subordinate expertise in the mediated relationship. Using 151 unique matched sets of leader and subordinate reports obtained from 5 large Korean companies, we found that the positive relationship between LMX and leader effectiveness was mediated by leaders' negative feedback-seeking. Additionally, the positive relationship between LMX and leader negative feedback-seeking was stronger when perceived subordinate expertise was lower. Lastly, the indirect effect of LMX on leader effectiveness through leader negative feedback-seeking was stronger when perceived subordinate expertise was lower. These findings were obtained after controlling for leaders' power distance and goal orientations that might influence their motives to seek or avoid feedback. Theoretical and practical implications are discussed. 相似文献
