Optimal Prediction in Stochastic Regression Models with Application to the Analysis of Repeated Surveys

Several results relating to the optimal prediction of regression coefficients and random variables under a general linear model with stochastic coefficients are presented. These results are then applied to the analysis of repeated sample surveys over time. In particular, if the finite population can be modelled by a superpopulation model, a fully efficient method for the analysis of repeated surveys is proposed.     

Stochastic modelling of the hybrid survival curve

In this paper, building upon the idea of cross-sectional survival probabilities developed by Brouard (Espaces Popul Soc 2(14–15):157–168, 1986), we propose using stochastic models to study the evolution of a new type of survival curves called hybrid survival curve. We find that the three-factor survival model provides a better model fitting than the two-factor survival model. Furthermore, the three time-varying parameters are highly interpretable and their respective trends can be used as an indicator for the rectangularisation of survival curve. On top of that, we demonstrate how the time-varying parameters can be extrapolated into the future to obtain projected hybrid survival curves.     

(Not) talking about sex: youth, identity and sexuality

Young people remain inhibited in their exploration of sexuality not only by heterosexual morality and gendered power relations but also by their transitional status, yet the age dimension of youth and sexuality has been relatively neglected in recent research. This paper examines a number of social constraints on young people's opportunities for talk and discussion about sex, with reference to their experiences of sex education and services in sexual health. Based on interviews with 147 young women and young men and a separate survey of 400 clinic users, it emphasises the limited social acceptance of teenage sexuality and the forms of its regulation, which are both normative and relational. Attention to social relations with adults also shows how questions of sexual citizenship are closely connected to wider issues of social equality.     

Life Goals and Well-Being: Does Financial Status Matter? Evidence from a Representative Hungarian Sample

Previous research with the Aspiration Index suggests that the importance of intrinsic life goals (e.g. personal growth and relationships) is in positive association with indicators of well-being, whereas an orientation toward extrinsic life goals (e.g. wealth and appearance) is connected with decreased positive functioning. Our study extended the scope of previous research by analyzing the role of financial status (income and subjective financial status). Examining a nationally representative cross-sectional sample of 4,841 Hungarian adults, we found that after controlling for several sociodemographic variables intrinsic goal importance was in a positive relationship with subjective well-being (SWB) and meaning in life (ML), whereas the contribution of extrinsic life goals was weak to SWB and negative to ML. Moreover, no moderation effects were found for indices of financial status, indicating that the relationship between life goals and well-being is the same for poorer and for richer respondents. Results show that the basic assumptions of the Aspiration Index research are also valid when testing on a societal level.     

Fitness Profiles and Activity Patterns of Entering College Students

Abstract

Fitness levels of American youth have shown a marked decline in the last decade, according to recent studies. To determine whether such a tendency persists for entering college students, the authors evaluated 115 male and 143 female students for performance on the following fitness-related variables: (1) maximal oxygen consumption (estimated from Astrand cycling protocol), (2) body composition (skin-fold techniques), (3) muscle endurance (sit-up protocol), (4) muscle strength (bench-press protocol), and (5) joint flexibility (upper and lower body protocols).

Although neither men nor women exhibited high levels of cardiorespiratory fitness, the women in the study showed higher relative levels than their male counterparts. Both groups showed excellent levels of muscle strength (compared with normative standards), but they achieved only an average standard for muscle endurance. Findings of relatively low levels of cardiovascular fitness compared with levels of muscle strength, particularly in men, seem to be a reflection of an inappropriate concentration of physical activity.     

“If Rainbows Were Everywhere”: Nonmetropolitan SGM Youth Identify Factors That Make Communities Supportive

ABSTRACT

Sexual and gender minority (SGM) youth in nonmetropolitan communities face marginalization due to their SGM identities. Community support may mitigate the negative outcomes associated with marginalization. Using the strengths perspective, this study investigated the factors SGM youth identify as making their communities supportive. Interviews were conducted with SGM youth to explore their perceptions of their community, community climate, and the factors that contribute to making communities supportive to SGM youth. Findings revealed four supportive community factors: supportive people, SGM visibility, SGM resources and education, and SGM-inclusive policies. Implications include creating SGM resources and providing professional training on SGM issues.     

Community development--action research in community settings

This paper considers the concept of resilience and how the natural qualities supportive of resilience in children and families can best be nurtured. It argues that there is an emerging crisis in bureaucratised child protection systems that alienates and undermines both social workers and clients, and that runs counter to the spirit of resilience‐led practice. Responding to this crisis requires a new emphasis on relationships, strengths and the clients' social context in child and family social work. It also requires practitioners and students to reflect carefully on the nature of helping. The paper explores some of the implications of these ideas for social work practice, education and policy.     

Money Buys Financial Security and Psychological Need Satisfaction: Testing Need Theory in Affluence

The most prominent theory to explain the curvilinear relationship between income and subjective well-being (SWB) is need theory, which proposes that increased income and wealth can lead to increased well-being in poverty because money is used to satisfy basic physiological needs. The present study tests the tenets of need theory by proposing that money can buy happiness beyond poverty if the money satisfies higher-order needs. Findings indicate that in older adults (n = 1,284), as economic standing rises, so do individual perceptions of financial security (a safety need), which in turn increases overall life satisfaction. Further, a path model tested the degree to which financial security and psychological need satisfaction mediated the path from economic standing to life satisfaction and demonstrated the complete mediation through higher-order needs—there was a 66% reduction in the direct link through financial security and a 34% reduction through psychological need satisfaction. Discussion focuses on how these mediation and path models extend need theory.
