Despite growing concerns about foster placement instability, little information is available regarding the longitudinal patterns of placement histories among foster children. The purpose of the present study was to develop a charting system using child welfare records to facilitate a better understanding of longitudinal patterns of placement history for 117 foster children. The resulting Placement History Chart included all placements that occurred during the observed time period and accounted for various dimensions: number, length, type, and sequence of placements; timing of transitions; and total time in out-of-home care. The Placement History Chart is an effective tool for placing foster care experiences within a broader developmental context. As such, the Placement History Chart can be a valuable research tool for understanding various dimensions and variations of placement transitions among foster children by capturing sequences and cumulative risks over time. Furthermore, this chart can facilitate the development of intervention programs that are developmentally sensitive and effectively address particularly vulnerable subpopulations of foster children. 相似文献

Pay-What-You-Want (PWYW) is a participative pricing mechanism which is characterized by the fact that consumers have maximum control over the price they pay. We discuss the business relevance of PWYW and extend the findings of Kim et al. (2009) using latent class regression. Two different classes can be identified and transaction prices are explained by psycho- and socio-demographics. The estimation of the parameters shows that the internal reference price is a good predictor for the prices in class 1, whereas in the 2nd class the level of fairness and satisfaction with the product positively affect the final transaction prices. 相似文献

This article assesses Charles Tilly’s Durable Inequality and traces its influence. In writing Durable Inequality, Tilly sought to shift the research agenda of stratification scholars. But the book’s initial impact was disappointing. In
recent years, however, its influence has grown, suggesting a more enduring legacy. 相似文献

Concerns over poverty and health inequality are growing in South Korea. Using advanced statistical methods including lagged-dependent variable and fixed-effects approaches, we investigated whether experiencing material hardship (MH) was associated with self-rated health (SRH) among low-income households in South Korea. This study found that the experience of MH was positively associated with higher likelihood of reporting poor SRH (OR = 1.42, p < .05) and that experiencing two or more items of MH presented more harmful influence on SRH (OR = 2.02, p < .001). This study also found that the negative association between MH and SRH was stronger among the unemployed households. 相似文献

Previous studies find that some social groups are stuck in poverty traps because of network effects. However, these studies do not carefully analyze how these groups overcome low human capital investment activities. Unlike previous studies, the model in this paper includes network externalities in both the human capital investment stage and the subsequent career stages. This implies that not only the current network quality, but also the expectations about future network quality affect the current investment decision. Consequently, the coordinated expectation among the group members can play a crucial role in the determination of the final state. We define “overlap” for some initial skill ranges, whereby the economic performance of a group can be improved simply by increasing expectations of a brighter future. We also define “poverty trap” for some ranges, wherein a disadvantaged group is constrained by its history, and we explore the egalitarian policies to mobilize the group out of the trap. 相似文献

Thriving research has been dominated by a psychological perspective. Individuals are typically the unit of analysis and thriving is generally operationalized using psychological measures. This article discusses a race, class, and gender perspective that derives from feminist sociology, as well as its implications for thriving research. This perspective, which focuses on the role of race, class, and gender inequality in organizing social relations, draws attention to the need to recognize that both the likelihood that someone will face a challenge and their ability to thrive in the face of that challenge are determined largely by their location in the social hierarchy. It also demonstrates that distinctions must be made between thriving in the face of the routine challenges of daily life and thriving in the face of challenges that are an extraordinary part of life. Finally, the race, class, and gender perspective has implications for the development of interventions to promote thriving. Each of these issues is elaborated further with illustrations drawn from life history and focus group interviews with and field work conducted among drug-addicted women. 相似文献

Declining inter-industry wage dispersion in the US 总被引:1,自引:0,他引:1
Industrial effects have long been significant factors in wage inequality. Previous research indicates that wage differentials across industries were increasing through the mid 1980s. Using more recent data, however, we find that the level of inter-industry wage dispersion declined by 36% from 1986 to 2002 despite the continued trend towards increasing inequality in the labor force. This decline in inter-industry wage dispersion is evident across gender and educational groups. Using multilevel growth curve models, our multivariate results indicate that the decline is only weakly related to industrial changes in education, occupation or even productivity despite the fact that the latter variable had been a critical factor in the prior period. Indicators of globalization and downsizing also do not appear to explain this decline. For the more recent period, the most important factors associated with the narrowing of inter-industry wage dispersion are reduced unionization rates and the higher proportion of casual workers. We interpret these results as suggesting that firms may now be less economically obliged to pass on a portion of their rents to broad groups of workers and may instead be engaged in more idiosyncratic processes of negotiation with individual workers based on micro-level sources of bargaining power. 相似文献

By restricting the number of age groups to two and by introducing continued fractions, the dynamics of populations with deterministically changing vital rates are completely specified at all times. Explicit expressions for the sequence of the product of population projection matrices are given. From these, relative age distribution and reproductive values to any desired accuracy are obtained as functions of the vital rates. Thus, the results given in this paper are stronger than any existing weak ergodic theorems. 相似文献

We investigate the impact of health shocks on wealth, using all four waves of the Health and Retirement Study, and estimate
not only the short-term effect but also the long-term effect of health shocks on wealth of the elderly. We find that new health
events lower wealth in elders during the period in which such health shocks occur, but the impact tends to disappear over
time. We also find that health shocks result in greater wealth depletion when they occur later in life. Together with existing
health problems, the overall impact of health problems on wealth increases over time.
