Objective. This article examines how events—such as changes in household composition, employment status, disability status, and economic conditions—affect poverty entries and exits. We also examine whether the role these events play in poverty transitions differs in the pre‐ and post‐welfare‐reform periods. Methods. The analysis uses discrete‐time multivariate hazard models along with monthly, longitudinal data from the 1988, 1990, and 1996 panels of the Survey of Income and Program Participation (SIPP). Results. Analyses show that many events are related to the likelihood of entering and exiting poverty. Of the trigger events examined, individuals living in households that experience a loss or gain of employment are the most likely to enter and exit poverty. We also find that changes in employment are more important in the 1996 to 1999 time period—after welfare reform—than in the 1988 to 1992 time period—prior to welfare reform. Finally, changes in household composition, disability status, and educational attainment are found to play a role in throwing people into poverty and helping them exit from poverty in both time periods. Conclusions. There is no single path into or out of poverty, suggesting that multiple policies can be considered to help alleviate poverty. 相似文献

The experiment reported here investigated infants' concept of intention, as well as the relation among intention understanding, general productive vocabulary, and internal state language production during the 2nd year. Results from an imitation task indicated that 18‐month‐olds are better able to differentiate between intentional and accidental actions than 14‐month‐olds. Although there was no relation between infants' performance on the intention task and their general productive vocabulary, internal state language production at 30 months was predicted by infants' ability to differentiate between intentional and accidental actions about a year earlier. These findings shed light on the developmental progression of infants' concept of intention, as well as on the continuity between infants' understanding of intentional action and their ability to use internal state words. 相似文献

There are two opposing views on the role of private foundations, especially the corporate foundations. Korean people seem
to think that corporate foundations have been used as a device to transfer the wealth of rich families with favourable tax
treatment. Considering the curret status and past performance of corporate foundations, the evidence seems to lend support
to this negative view at the moment. The corporate foundations have performed within a very limited range of activities and
have not made many efforts to develop non-profit activities to meet the expectations of Korean society. The negative view
does not imply that corporate foundations have not contributed to Korean society. But the negative view can be regarded as
a criticism of the past performance of corporate foundations and the way they have been managed.

The Alevi comprise a specific ethnic group in Turkey of especial interest. In presenting a case study of an Alevi community in Ankara that arose out of internal urban migration, the present paper delineates the way in which the Alevis have moved away from constituting a counterculture during the period of the Ottoman period to comprising a working class subculture of great organizational and political potential in contemporary Turkey. The paper also describes the ethnic markedness of the Alevi community and the problems that arise out of this markedness. 相似文献

自然灾害会依严重程度对事件经历者的心理产生重大影响,异地安置是自然灾害发生后较为普遍的干预措施,大部分已有研究表明异地安置对受灾者灾后身心具有负面影响。本文利用2009年2月对汶川地震受灾地区随机抽样所抽取的10个地震受灾县的100个贫困村庄的3000户家庭的抽样调查数据,在通过GIS工具变量回归有效控制地震灾害损害影响的基础上,估计了地震灾害以及灾后异地安置对儿童心理和学业的影响。结果表明,地震损害中的学校损毁程度(相对于家庭住房和成员伤亡)对儿童心理的消极影响最大,同时也影响儿童的灾后入学率;在控制灾害损害影响的条件下,学校的县内异地安置对儿童心理具有积极影响,学校的县外异地安置则有助于提高灾后儿童学业表现,而家庭的长期异地安置对灾后的入学率和学业表现都具有显著的积极影响。这些结果并不支持多数已有研究所得出的异地安置具有负面影响的结论,也为自然灾害的灾后应对措施的设计提供参考依据。 相似文献

We investigate the influence of national culture on corporate investment–cash flow sensitivity. We conjecture that national culture shapes managerial perceptions of information asymmetry and agency problems, thus impacting the investment–cash flow relationship. We document empirical evidence in support of our claim. By linking the investment–cash flow sensitivity to cultural differences, our findings show that, while collectivism has an attenuating influence, uncertainty avoidance, power distance and masculinity have a reinforcing effect on the relationship between cash flow and investment. Our results hold for a sample of 205,268 firm‐years across 24 OECD countries between 1990 and 2017, and are robust after accounting for alternative statistical approaches, sample compositions and measures of cultural dimensions, along with controls for institutional and governmental factors. In addition, by decomposing cash flow into uses and sources of funds in a dynamic multi‐equation model, where firms make financing and investment decisions jointly subject to the constraint that sources must equal uses of cash, we find that national culture shapes how firms react to changes in cash flow. 相似文献

This paper provides an evaluative overview of the new venture survival literature. Since Stinchcombe's primary attempt to explain the mortality rates of new ventures, different research fields, including entrepreneurship, management and sociology, have devoted considerable attention to the antecedents of new venture survival. Despite this lively research commitment, a comprehensive review of the literature on new venture survival – as one of the most essential performance measures for new ventures – is missing. Covering 54 years of research, this paper provides an overview of the factors affecting new venture survival and highlights important methodological aspects in this research field. The review concludes by discussing opportunities for future research. 相似文献

Despite increasing interest in human resource management (HRM) implementation as an explanation for the association between HRM and firm performance, considerable confusion remains about what implementation means. In order to develop conceptual definitions of HRM implementation and implementation effectiveness, this study builds on three different literatures outside the HRM field (strategy, innovation, and change management), which have addressed this topic extensively. As a result, implementation is characterized as a dynamic process, involving the interaction among multiple actors, starting with the adoption of a new practice and ending with its routinization. This is distinguished from implementation effectiveness as an outcome of that process. The study helps to achieve construct clarity, hence providing a more solid basis for future research and allowing for a better consolidation of findings. The authors also develop an agenda for further research by reviewing a number of theoretical and methodological approaches that have been used in implementation research across fields, including HRM. Overall, the study aims to establish implementation research as a highly relevant academic and practical quest not only in HRM, but also in other management literatures. 相似文献

In drug development, treatments are most often selected at Phase 2 for further development when an initial trial of a new treatment produces a result that is considered positive. This selection due to a positive result means, however, that an estimator of the treatment effect, which does not take account of the selection is likely to over‐estimate the true treatment effect (ie, will be biased). This bias can be large and researchers may face a disappointingly lower estimated treatment effect in further trials. In this paper, we review a number of methods that have been proposed to correct for this bias and introduce three new methods. We present results from applying the various methods to two examples and consider extensions of the examples. We assess the methods with respect to bias of estimation of the treatment effect and compare the probabilities that a bias‐corrected treatment effect estimate will exceed a decision threshold. Following previous work, we also compare average power for the situation where a Phase 3 trial is launched given that the bias‐corrected observed Phase 2 treatment effect exceeds a launch threshold. Finally, we discuss our findings and potential application of the bias correction methods. 相似文献
