This article highlights three dimensions to understanding children's well‐being during and after parental imprisonment which have not been fully explored in current research. A consideration of ‘time’ reveals the importance of children's past experiences and their anticipated futures. A focus on ‘space’ highlights the impact of new or altered environmental dynamics. A study of ‘agency’ illuminates how children cope within structural, material and social confines which intensify vulnerability and dependency. This integrated perspective reveals important differences in individual children's experiences and commonalities in broader systemic and social constraints on prisoners’ children. The paper analyses data from a prospective longitudinal study of 35 prisoners’ children during and after their (step) father's imprisonment to illustrate the arguments. 相似文献

As part of the celebration of the 40th anniversary of the Society for Risk Analysis and Risk Analysis: An International Journal, this essay reviews the 10 most important accomplishments of risk analysis from 1980 to 2010, outlines major accomplishments in three major categories from 2011 to 2019, discusses how editors circulate authors’ accomplishments, and proposes 10 major risk-related challenges for 2020–2030. Authors conclude that the next decade will severely test the field of risk analysis. 相似文献

ABSTRACTThe cost and time of pharmaceutical drug development continue to grow at rates that many say are unsustainable. These trends have enormous impact on what treatments get to patients, when they get them and how they are used. The statistical framework for supporting decisions in regulated clinical development of new medicines has followed a traditional path of frequentist methodology. Trials using hypothesis tests of “no treatment effect” are done routinely, and the p-value < 0.05 is often the determinant of what constitutes a “successful” trial. Many drugs fail in clinical development, adding to the cost of new medicines, and some evidence points blame at the deficiencies of the frequentist paradigm. An unknown number effective medicines may have been abandoned because trials were declared “unsuccessful” due to a p-value exceeding 0.05. Recently, the Bayesian paradigm has shown utility in the clinical drug development process for its probability-based inference. We argue for a Bayesian approach that employs data from other trials as a “prior” for Phase 3 trials so that synthesized evidence across trials can be utilized to compute probability statements that are valuable for understanding the magnitude of treatment effect. Such a Bayesian paradigm provides a promising framework for improving statistical inference and regulatory decision making. 相似文献

Reuband’s article purports to report empirical results that seem to contradict the widely held view of mail surveys. This assertion is made possible only by an unclear statement of hypotheses and a selective perception of the literature. The data analysis is based on techniques from the 1960s and 1970s; modern methods are not even mentioned. Although all the results reported in the article are based on local surveys conducted by a university institute, these are generalized to national surveys in general. The main points of this critique are methodological: careless literature review, lack of concrete hypotheses, inefficient data analysis and generalizations without empirical foundation. 相似文献

The main role of traffic police enforcement can be seen as preventing road users from committing offences, which can be related to road crashes and injuries. As the operating principle underlying the impact of police enforcement a deterrence effect has been discussed repeatedly, whereas from a sociological perspective the importance of “Norm Internalisation” has been emphasised. Thus, the present paper aims at comparing the influence of “Norm Internalisation” and the variables constituting the deterrence effect on the compliance with rules in road traffic. Based on a secondary analysis of data from a project on behavioural determinants of police surveillance carried out by the “Institute of Applied Transport and Tourism Research” (IVT) on behalf of the Federal Highway Research Institute (BASt) an operationalisation of the construct “General Norm Orientation” is developed. In several subsequent steps of statistical analysis patterns of correlations with variables from Opp’s “Theory of Law Obedience” are revealed. Results show a sufficiently high internal consistency (α = 0,82) of the scale “General Norm Orientation” and significant correlations with variables from Opp’s theory. The directions of these correlations are as expected and confirmed by multivariate analyses. Results are discussed with respect to their implications for influencing road users’ behaviours. 相似文献

This study examined racial differences between mistreated and abused older African American and Caucasian men. The racial and gender differences of their perpetrators were also examined. Data from a single elder abuse provider agency in the State of Illinois were analyzed. Differences with respect to physical abuse, emotional abuse, physical neglect, deprivation, confinement, and financial exploitation were examined, as were demographic characteristics and limitations of victims and abusers. 相似文献

According to the most influential contribution of recent years to the comparative study of advanced welfare states, Esping-Andersen’s ’Three Worlds of Welfare Capitalism‘, the welfare state basically comes in three variants: as a social-democratic, a conservative, or as a liberal regime. Yet, at a closer look, in particular the ’conservative‘ regime-type represents a highly problematic category. The article claims that the major problems of Esping-Andersen’s typology and theory originate from his sole focus on the class conflict and his neglect of the religious cleavage. Major theoretical contradictions and empirical puzzles of his approach can be solved if we take not only the impact of the catholic social doctrine on the development of the welfare state into account, but consider also the influence of social protestantism, especially that of protestant dissent and of protestant non-conformism. The paper substantiates this claim with data for the early formative period of the welfare state (1890–1920) as well as for the high-time of the welfare state from the 1960s to the 1990s. 相似文献
