We deal with the double sampling plans by variables proposed by Bowker and Goode (Sampling Inspection by Variables, McGraw–Hill,
New York, 1952) when the standard deviation is unknown. Using the procedure for the calculation of the OC given by Krumbholz and Rohr (Allg.
Stat. Arch. 90:233–251, 2006), we present an optimization algorithm allowing to determine the ASN Minimax plan. This plan, among all double plans satisfying
the classical two-point-condition on the OC, has the minimal ASN maximum. 相似文献

Children of immigrant background, despite problems with acculturation, poverty, and discrimination, have better mental health than children of native parents. We asked whether this is a result of immigrant families' characteristics such as family structure and relations. Using a new comparative study on the integration of immigrant‐background youth conducted in England, Germany, the Netherlands, and Sweden (N = 18,716), particularly strong associations with mental health (internalizing and externalizing problems) were found for family structure, family cohesion, and parental warmth. Overall, half of the advantage in internalizing and externalizing problems among immigrant‐background youth could be accounted for by our measures of family structure and family relations, with family cohesion being particularly important. 相似文献

ABSTRACTMilitary families face not only the same challenges as other families, but also unique issues due to their military involvement. Parenting programs for civilian families can be helpful, but they do not generally cover the specific issues faced by military families. The purpose of this qualitative study was to gather information from a focus group of eight service providers about the types of issues that affect military families, such that content and delivery of workshops at a social service agency could be formed to specifically cater to military families. This study utilized a phenomenological approach, and analyses revealed areas for social service involvement around the cycle of deployment. Specifically, social services could be helpful by using psychoeducational and normalization techniques around the five major themes that resulted from this study: (1) the issues of servicemembers psychologically withdrawing before deployment, (2) family cohesion and connectedness during and after deployment, (3) family stability during reintegration of the service member, (4) military families experience many of the same challenges that nonmilitary families do (such as domestic violence and financial issues), and (5) utilizing a military culture framework for all military family programs. 相似文献

Research on sex differences in occupational attainment suggests that working men and working women attain essentially the same mean level of occupational attainment and do so through quite similar processes. A possible explanation for these similarities is that the sample of working women contains an overrepresentation of successful women, since women who can afford not to work will stay out of the labor force unless they find a job commensurate with their education. This we define as a censoring problem. By extending a technique developed by Heckman, we can estimate the structural parameters for all women, regardless of current employment status. This procedure allows us to assess the impact of the censoring problem on women's occupational attainment equations. 相似文献

Data on the fertility of teachers in grant earning schools in England and Wales were collected in 1955 as part of a general survey into the social characteristics of teachers. The survey was financed by the Nuffield Foundation with a contribution from the Population Investigation Committee. A subsequent article will discuss some possible determinants of fertility and in particular the interrelationship between social mobility and fertility. The present note describes changes in cohort fertility of teachers since 1915 and compares average family size with that of other sections of the population. The average number of children per married male teacher declined from 1.81 for the pre-1920 cohort to 1.47 for 1930–34. Segmental data after 1935 indicate a rise to approximately 2 children per family. Comparison with the Family Census suggests that the number of children of teachers is between 10% and 20% below that of all professions combined when the age at marriage of the wife is taken into account. 相似文献

ABSTRACT Trauma-informed care (TIC) in social service organizations means that the organizations operate with the understanding that everyone involved has possibly experienced trauma in their lifetime. This qualitative study examined local service organizations’ usage of the 5 main principles of TIC: safety, trustworthiness, collaboration, empowerment, and choice (as developed by Fallot & Harris, 2006). Ten focus groups (n = 69) and 6 individual interviews (n = 6) with employees from administration through management were interviewed such that almost all facets of each agency were represented. The participants were asked about their agencies’ policies and practices for utilizing the 5 principles of TIC. The results suggest that the vast majority of organizations in this study implemented many of the principles of TIC with clients, though they had not labeled their practices as “trauma-informed.” However, although clients were receiving TIC, some of the principles were neglected as they pertain to staff, such as choice and empowerment. The findings of this study suggest that agencies are unaware of the relevance of TIC as it relates to staff. It is recommended that future research examine whether the use of TIC in agencies prevents “burnout,” high turnover rates, and vicarious traumatization of staff. 相似文献

Our study explores the adoption of Facebook and Twitter by candidates in the 2013 German Federal elections. Utilizing data from the German Longitudinal Election Study candidate survey fused with data gathered on the Twitter and Facebook use of candidates, we draw a clear distinction between Facebook and Twitter. We show that adoption of both channels is primarily driven by two factors: party and money. But the impact of each plays out differently for Facebook and Twitter. While the influence of money is homogenous for Facebook and Twitter with the more resources candidates have, the more likely they are to adopt, the effect is stronger for Facebook. Conversely, a party’s impact on adoption is heterogeneous across channels, a pattern we suggest is driven by the different audiences Facebook and Twitter attract. We also find candidates’ personality traits only correlate with Twitter adoption, but their impact is minimal. Our findings demonstrate that social media adoption by politicians is far from homogenous, and that there is a need to differentiate social media channels from one another when exploring motivations for their use. 相似文献

For many years, comparative welfare state research has followed a ‘methodological nationalism’ in the sense that countries were treated as independent units. Yet the recent ‘spatial turn’ in comparative politics has also influenced welfare state research. For some years now, the field has been witnessing a growing interest in questions about interdependencies and policy diffusion between countries. In this article, we provide a structured overview of the state of the art in the policy diffusion and transfer literature that deals specifically with social policy. We present and critically evaluate existing theoretical concepts and quantitative and qualitative methodological approaches that enable the analysis of interdependencies between countries. Moreover, we summarize the empirical findings of quantitative and qualitative studies on the diffusion and transfer of social policy, from some pioneering studies to the latest findings. Against this background we point out what we believe to be promising avenues for future research. We focus on five areas: theoretical work on the mechanisms underlying diffusion and transfer; methodological approaches; the impact of domestic institutions and policy characteristics on social policy diffusion and transfer; programme‐specific dynamics; and the systematic combination of horizontal and vertical interdependencies. 相似文献

Household composition of older unmarried women in Hungary is analyzed using data from the 1984 microcensus. The principal determinants of household composition investigated are kin availability — the number of living children, siblings, and parents — health status, marital status, age, and income. A multinomial logit model distinguishing among five household types reveals that number of children, severe disabilities, age and income are all strongly related to household composition. Trends in fertility and mortality patterns suggest that kinship patterns will change in coming years; these results imply that household composition will, in turn, change as well. 相似文献
