Bradford Hill (BH) viewpoints are widely used to assess causality in systematic reviews, but their application has often lacked reproducibility. We describe an approach for assessing causality within systematic reviews (‘causal’ reviews), illustrating its application to the topic of income inequality and health. Our approach draws on principles of process tracing, a method used for case study research, to harness BH viewpoints to judge evidence for causal claims.  相似文献

Deinstitutionalization is a core policy for the development of services for people with intellectual disabilities (ID) in western countries. Nonetheless, although a western country, deinstitutionalization is not well advanced in Israel. In order to shed light on this phenomenon, we explore the hegemony of ID as reflected in Israeli legislation. The analysis shows a biomedical hegemony; ID is depicted as a form of medical and social deviance. Israel’s legislation reflects paternalistic views of persons with ID, who are largely seen as vulnerable objects of pity, to be cared for and protected.  相似文献

Individual development accounts (IDAs) have been adopted in communities across the country as a way of helping lower-income individuals accrue financial assets. These programs match the savings of program participants if they invest them in the purchase of a home, the creation or expansion of a business, or additional education. Beyond the financial benefits of holding assets, scholars have argued that they should also result in psychological benefits such as enhanced future orientations and decreased depression. This study tests this argument with data from a randomized controlled experiment involving 1,103 applicants to an IDA program. The findings show that assignment to the IDA program was not associated with either future orientation or depression 10 years later. The value of assets held at that time, however, was found to be negatively associated with depression. In addition, self-reported financial stress was found to be negatively associated with future orientation and positively associated with depression.  相似文献

A linear errors-in-variables (EIV) model that contains measurement errors in the input and output data is considered. Weakly dependent (α- and ?-mixing) errors, not necessarily stationary nor identically distributed, are taken into account within the EIV model. Parameters of the EIV model are estimated by the total least squares approach, which provides highly non linear estimates. Because of this, many statistical procedures for constructing confidence intervals and testing hypotheses cannot be applied. One possible solution to this dilemma is a block bootstrap. An appropriate moving block bootstrap procedure is provided and its correctness proved. The results are illustrated through a simulation study and applied on real data as well.  相似文献

Attitudes towards risk and uncertainty have been indicated to be highly context‐dependent, and to be sensitive to the measurement technique employed. We present data collected in controlled experiments with 2,939 subjects in 30 countries measuring risk and uncertainty attitudes through incentivized measures as well as survey questions. Our data show clearly that measures correlate not only within decision contexts or measurement methods, but also across contexts and methods. This points to the existence of one underlying “risk preference”, which influences attitudes independently of the measurement method or choice domain. We furthermore find that answers to a general and a financial survey question correlate with incentivized lottery choices in most countries. Incentivized and survey measures also correlate significantly between countries. This opens the possibility to conduct cultural comparisons on risk attitudes using survey instruments.  相似文献

Measurement error is well known to cause bias in estimated regression coefficients and a loss of power for detecting associations. Methods commonly used to correct for bias often require auxiliary data. We develop a solution for investigating associations between the change in an imprecisely measured outcome and precisely measured predictors, adjusting for the baseline value of the outcome when auxiliary data are not available. We require the specification of ranges for the reliability or the measurement error variance. The solution allows one to investigate the associations for change and to assess the impact of the measurement error.  相似文献

The paper presents research findings on the initial stages of the life cycle of cross-sector partnerships in the social services. The findings clearly show the importance and impact of the initial stages on the establishment and institutionalization of the partnerships over time. These stages are mainly characterized by clarifying the common goals of the partnership, mobilizing support to achieve the goals, overcoming resistance and relieving fears while convincing opponents to change their attitudes toward the partnership, and formalizing and constructing administrative processes and procedures. Special attention is given to the emotional energy that the management and workers invest in the initial stages in order to overcome barriers as well as ideological, cultural, and procedural gaps between the partner organizations. The relationships between selected organizational properties that typify the initial stages of cross-sector partnerships and the achievement of goals and outcomes are presented, analyzed, and discussed.

A widely shared intuition holds that individual control over money matters for the decision process within the household and the subsequent distribution of resources and welfare. As a consequence, there are good reasons to depart from the unitary model of the household and to explore the possibilities offered by models of the family accounting for several decision makers in the household and for the potential impact of tax reforms on the balance of power. This paper summarizes both the methodological and empirical findings presented in the next three papers of this special issue of the Review of the Economics of the Household. This series of contributions primarily entails a concrete comparison of the policy implications of the choice between the unitary and a particular multi-person representation: the collective representation. On the one hand, it suggests a methodology to implement the collective model of labor supply in a realistic context where participation is modeled together with working hours, and where the full tax-benefit system is accounted for. On the other hand, the empirical part relies on comprehensive simulations of tax reforms in Belgium, France, Germany, Italy, Spain, and the United Kingdom, and allows to quantify the distortions that may affect policy recommendations based on the unitary model.

Introduction: In 2005, the International Committee of Medical Journal Editors (ICMJE) proposed that all submitted trials in all 11 member journals must be prospectively registered in order to be considered for publication. Registering drug trials was meant to reduce the likelihood of selective reporting. The aim was to determine the proportion of antipsychotic and antidepressant trials that were registered.

Methods: We searched in Pubmed for all randomized controlled trials of any antidepressant or antipsychotic published between July and December 2014. The primary objective was to determine the proportion of trials that were registered. Secondary objectives included comparing the reporting of methodological details and positive study findings between registered and unregistered trials.

Results: Of the 67 studies identified, 58% were registered. 75% of the antipsychotic trials and 51% of the antidepressant trials were registered, respectively. Registered trials were more likely to report important methodological details associated with risk of bias in RCTs. There was no significant difference in trials reporting positive outcomes for the study intervention between registered and unregistered trials.

Conclusion: Approximately 60% of published antidepressant and antipsychotic drug trials during July to December 2014 were registered. Unregistered trials were less likely to report important methodological details.  相似文献

Contemporary processes of individualization push people to construct single‐handedly their own identities. This urge runs counter to a fundament of sociology, which proposes that identities are social products that must be validated through social relations. Based on participant observation and in‐depth interviews with life coaches and their clients, I investigate life coaching as a social institution that aims to resolve the paradoxical nature of the desire for self‐creation. Locating life coaching in the larger identity‐fashioning market, this article illustrates how the artificial nature of outsourced social relations reconciles two apparently contradictory desires: the “need for help” and “wanting to find it on my own.” Three mechanisms are involved: creating an independent social space where identities can be crafted away from significant others; deliberately deemphasizing the coach and intentionally underwriting personal authorship; and encouraging clients to root identities in the social world while promoting an instrumental view of sociality. The article discusses the blurring of boundaries between intimate social relations and utilitarian market logic, and the implications of the ongoing outsourcing of identity support that reinforces the privileged ideal of self‐made identities.  相似文献
