ABSTRACT

In recent decades, social housing in the UK has increasingly become the preserve of the poorest in society. This paper is the first to investigate how the child outcome penalties associated with social housing tenure have changed over time across UK cohorts. I compare the differences in the cognitive, mental health, and physical health outcomes of children in social housing with children in non-social housing and evaluate whether these tenure differences have changed between the 1970 British Cohort Study (BCS) and the 2000 Millennium Cohort Study (MCS). I find that in both cohorts, children in social housing exhibit worse outcomes across all three dimensions (cognitive, mental health, and physical health) than children in non-social housing. For cognitive and physical health outcomes, however, the tenure difference has narrowed between the two cohorts, while for mental health outcomes, the tenure difference has widened. These results suggest that children have experienced a relative worsening in their mental health outcomes across cohorts, but also a relative improvement in both their cognitive and physical health outcomes. The findings suggest that policies aimed at reducing tenure inequalities in child outcomes should focus on mental health development in the early years.  相似文献

Previous studies have suggested that Asian parents’ high academic expectations can lead to negative mental health outcomes among Asian American youth. We explore this hypothesis by analyzing data collected in an affluent, suburban high school with a large Asian American population. We examine the relationships between parent expectations, students’ relationships with their parents, and mental health outcomes among Asian American (predominantly Indian American and Chinese American) and white youth. We find that the quality of parent-child relationships is associated with mental health outcomes and that the association between parent expectations and mental health outcomes is insignificant after controlling for these relationships. We discuss significant differences by race and gender. The findings presented expand our understanding of the influence of Asian parents. They suggest that focusing on improving parent-child relationships, as opposed to altering parents’ expectations, might lead to improved mental health outcomes for Asian American youth, particularly for those in affluent communities.  相似文献

Choice under complete uncertainty when outcome spaces are state dependent   总被引:1,自引:1,他引:0  
One central objection to the maximin payoff criterion is that it focuses on the state that yields the lowest payoffs regardless of how low these are. We allow different states to have different sets of possible outcomes and show that the original axioms of Milnor (1954) continue to characterize the maximin payoff criterion, provided that the sets of payoffs achievable across states overlap. If instead payoffs in some states are always lower than in all others then ignoring the “bad” states is no longer inconsistent with these axioms. Similar dependence on overlap of outcome spaces across states holds for the minimax regret and maximin joy criteria.   相似文献

Extensive research has shown the positive impact of conditional child benefits on child outcomes. However, there is limited work on the impact of universal child benefit payments on how families spend on child outcomes. Our study explores this issue. This study examined the relationship between child benefit payments on child outcome expenditures using longitudinal data from the Korean National Survey of Tax and Benefit (N = 3681 households) and a household- and year-fixed effects regression model. We found that child benefit payments are positively associated with child outcome expenditures across family income groups. Furthermore, the analysis results suggest that compared to high-income family groups, low- and middle-income family groups increase spending on child outcome expenditures in response to child benefit payments. Finally, the policy implications of this are discussed.  相似文献

Adopting a multilevel approach, this study extends the current understanding of workplace incivility by examining the cross-level associations between team climate for incivility, team size and team norms with regard to competitiveness on employees’ well-being associated with incivility at work. Using a sample of 637 employees nested in 50 work teams, the results revealed a direct negative effect of uncivil team climates on employee job-related affective well-being, over and above employees’ personal experience of uncivil behaviour. As hypothesized, competitive norms significantly moderated the negative effect of experienced incivility on affective well-being, suggesting that competitive team environments may buffer the negative consequences of workplace incivility through a team sensemaking process. Utilizing Social Comparison Theory (comparing how they are treated) and climate strength literature, this study also found team size to be a significant moderator of the incivility–well-being relationship, with members of smaller work teams experiencing more detrimental effects of uncivil acts. Together, these findings suggest that the magnitude of the negative effect of uncivil behaviour is dependent on the composition and incivility climate of work teams. The results of this study have important implications for designing individual- and team-level interventions aimed at addressing uncivil behaviour and climates in the workplace.  相似文献

Key concepts in efficiency analyses are efficiency and effectiveness. Efficiency is popularly connected to ‘doing the things right’ and effectiveness to ‘doing the right things’. The paper elaborates upon the latter concept within a setting where resources are transformed into outputs under the control of a public provider, while outcomes with outputs as inputs represent higher social goals, but this production is outside the public provider׳s direct control. A new measure of overall preference effectiveness is introduced and its decomposition into output-oriented efficiency and output-mix efficiency is shown. The monumental task of getting the necessary information for calculating effectiveness is highlighted.  相似文献

Most clinical studies, which investigate the impact of therapy simultaneously, record the frequency of adverse events in order to monitor safety of the intervention. Study reports typically summarise adverse event data by tabulating the frequencies of the worst grade experienced but provide no details of the temporal profiles of specific types of adverse events. Such 'toxicity profiles' are potentially important tools in disease management and in the assessment of newer therapies including targeted treatments and immunotherapy where different types of toxicity may be more common at various times during long-term drug exposure. Toxicity profiles of commonly experienced adverse events occurring due to exposure to long-term treatment could assist in evaluating the costs of the health care benefits of therapy. We show how to generate toxicity profiles using an adaptation of the ordinal time-to-event model comprising of a two-step process, involving estimation of the multinomial response probabilities using multinomial logistic regression and combining these with recurrent time to event hazard estimates to produce cumulative event probabilities for each of the multinomial adverse event response categories. Such a model permits the simultaneous assessment of the risk of events over time and provides cumulative risk probabilities for each type of adverse event response. The method can be applied more generally by using different models to estimate outcome/response probabilities. The method is illustrated by developing toxicity profiles for three distinct types of adverse events associated with two treatment regimens for patients with advanced breast cancer.  相似文献

Massive Open Online Courses (MOOCs) have gained traction as resources for professional development. This article presents the method that we used to evaluate a professional development MOOC for postdoctoral trainees that was created by a university consortium in the US. Most approaches to evaluating MOOCs focus on analysis of participation, outcomes from course assignments, self-reported learning outcomes, course completion and user pathways through the online content or clickstream data. Few published evaluations describe in detail how learning happens within online courses and the anticipated medium and longer term cognitive and behavioral outcomes on participants. This work aims to guide those who are designing, implementing and evaluating MOOCs through applying theories of change to focus evaluation on the process of learning. This approach can be used as a complement to traditional approaches for evaluating MOOCs. We described how we worked with the MOOC team building the content to develop a theory of change for each module (or lesson) within the MOOC and used the theory of change to guide evaluation of short and medium term participant cognitive, affective and attitudinal, and behavioral outcomes. Finally, we share lessons learned and suggestions for implementing theories of change in both the design and evaluation phases of MOOC development.  相似文献
