Residential mobility and the spatial dispersion of personal networks: Effects on social support

Using a representative national sample of personal networks, this article explores how the spatial dispersion of networks, residential mobility and social support are linked. Three issues will be addressed here. Firstly, how is the spatial dispersion of personal networks related to individuals’ social characteristics, network composition and residential mobility? Secondly, how do the spatial dispersion of networks, residential mobility and their combined effect influence the number and (thirdly) the structure of emotional support ties? Results showed that the extent of the support was affected neither by the geographical distribution of the networks nor by residential mobility. Living far from one's birthplace, however, exerted two distinct, and opposite effects on the support network structure. On the one hand, mobility led to high spatial dispersion of personal contacts, which in turn favored a sparsely knit network centered around the mobile individual. On the other hand, by controlling for the effect of distance between the contacts, we found that individuals that cited long-distance ties tended to be part of more transitive support networks than those that cited local ties. We interpreted the latter effect as evidence that transitive ties may survive greater spatial distances than intransitive ones. These findings are discussed in view of spatial mobility and social network research.     

Communication and representation of risk in health crises: the influence of framing and group identity / Comunicación en crisis sanitarias y representación del riesgo. La influencia del framing y la identidad grupal

Based on the Social Representations Theory (SRT) applied to the social construction of risk and the role played by group identities, this study examines the construction of risk created by the mass media in health epidemics. An experimental design with split-ballot questionnaire and 319 participants was used in which message framing (human interest vs. attribution of responsibility) and proximity (high vs. low) were manipulated for a high invulnerability identity (youth) vs. a low invulnerability identity (elderly) population. Results showed that the human interest framing increased the perception of risk, especially when the proximity of the epidemic was high; this effect was explained by people’s emotional response. Furthermore, youth projected the risk towards ‘the other’ in order to protect their invulnerability identity. Finally, we stress the importance of the SRT on a theoretical and applied level for risk communication in health crises.     

Noninformative priors for linear combinations of normal means with unequal variances

For normal populations with unequal variances, we develop matching priors and reference priors for a linear combination of the means. Here, we find three second-order matching priors: a highest posterior density (HPD) matching prior, a cumulative distribution function (CDF) matching prior, and a likelihood ratio (LR) matching prior. Furthermore, we show that the reference priors are all first-order matching priors, but that they do not satisfy the second-order matching criterion that establishes the symmetry and the unimodality of the posterior under the developed priors. The results of a simulation indicate that the second-order matching prior outperforms the reference priors in terms of matching the target coverage probabilities, in a frequentist sense. Finally, we compare the Bayesian credible intervals based on the developed priors with the confidence intervals derived from real data.     

Graphic Feedback,Performance Feedback,and Goal Setting Increased Staff Compliance With a Data Collection Task at a Large Residential Facility

Because of budgetary constraints, human service organizations frequently expect consultants to recommend methods to enhance staff performance that require little or no additional funding. The current study utilized a multiple baseline across settings design to evaluate and compare the effects of a single intervention and a packaged intervention including graphic feedback and goal setting on approximately 200 direct care staff as a group, to improve the data collection procedure at a residential treatment facility. The single intervention showed some improvement, whereas the packaged intervention yielded substantial improvements and was maintained.     

Sexual fantasy experiences and guilt among conservative Christians: An exploratory study

This study examines the sexual fantasy experiences and cognitive‐affective evaluations in a sample of conservative Christians. The study also operationalizes and documents fantasy guilt as an entity distinct from the more broadly defined category of sex guilt. Respondents reported normative fantasy categories and frequencies of fantasy occurrences. Concomitantly, fantasy episodes were experienced along with substantial to high levels of guilt over fantasizing. Findings show a complex interrelationship between a subject's cognitions, emotions, and fantasy guilt. These point to the import this sample gives to learned cognitions in furthering guilt, over and above the content or frequency of the fantasy experience itself.     

Does alcohol consumption reinforce mental problems in adolescence?

The main goal of this article is to provide empirical evidence that alcohol consumption reinforces the occurrence of mental illnesses even at early stages of life. We control probit estimations for unobserved heterogeneity and endogeneity. We have drawn a sample of 73,024 individuals from the Spanish National Survey on Drug Use in the School Population (2000, 2002, 2004). Our results confirm our theoretical hypothesis that alcohol consumption has a negative influence on youth state of health, but the magnitude of this influence is lower once we controlled for unobserved heterogeneity and endogeneity. Gender differences reveal that females are more likely to have been prescribed tranquilizers, and they are also more vulnerable to alcohol consumption than males are. As effective instruments to improve young people well-being, we suggest increasing the price of liquors and a greater parental control in how their children spend their available budget, and more important, in how they feel.     

Bayesian estimation procedure in multiprocess non-linear dynamic generalized model

The multiprocess dynamic model provides a good framework for the modeling and analysis of the time series that contains outliers arid is subject to abrupt changes in pattern. In this paper we extend the multiprocess dynamic generalized linear model to allow for a known non-linear parameter evolution and predictor functions. This is done by approximating the non-linear function by a linear function based on a first order Taylor series expansions. This model has nice properties such as insensitivity to outliers and quick reaction to abrupt changes of pattern.     

Community Involvement: Opportunities and Challenges in Socializing Adults to Participate in Society

The concluding article of this issue devoted to community involvement considers the unique perspective offered by each article on this topic in this issue, yet does so in the context of the commonalities among them. Most important of these commonalities, perhaps, is that all of the articles address, to some degree, the question of how adults can best be socialized to develop a habit of community participation. Some articles consider this question of encouraging community involvement in educational settings, while others consider the question in more general settings. Some articles focus on key conceptual processes, whereas others concentrate on practical issues in promoting involvement. Finally, virtually all of the articles consider the benefits of community involvement; some of the articles also explore the downside to efforts to promote community involvement.
