Familism Values,Family Time,and Mexican‐Origin Young Adults' Depressive Symptoms

Using longitudinal data across eight years, this study examined how parents' familism values in early adolescence predicted youths' depressive symptoms in young adulthood via youths' familism values and family time. We examined these processes among 246 Mexican‐origin families using interview and phone‐diary data. Findings revealed that fathers' familism values predicted male and female youths' familism values in middle adolescence. For female youth only, fathers' familism values also predicted youths' family time in late adolescence. The link between family time and young adults' depressive symptoms depended on parental acceptance and adolescent gender: Among female and male youth, family time predicted fewer depressive symptoms, but only when paternal acceptance was high. For female adolescents only, family time predicted fewer depressive symptoms when maternal acceptance was high but more depressive symptoms when maternal acceptance was low. Findings highlight family dynamics as the mechanisms through which familism values have implications for youths' adjustment.     

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.     

COST INCREASES DUE TO DEMAND UNCERTAINTY IN MRP LOT SIZING

This paper analyzes the cost increases due to demand uncertainty in single-level MRP lot sizing on a rolling horizon. It is shown that forecast errors have a tremendous effect on the cost effectiveness of lot-sizing techniques even when these forecast errors are small. Moreover, the cost differences between different techniques become rather insignificant in the presence of forecast errors. Since most industrial firms face demand uncertainty to some extent, our findings may have important managerial implications. Various simulation experiments give insight into both the nature and the magnitude of the cost increases for different heuristics. Analytical results are developed for the constant-demand case with random noise and forecasting by exponential smoothing. It is also shown how optimal buffers can be obtained by use of a simple model. Although the analysis in this paper is restricted to simplified cases, the results merit further consideration and study. This paper is one of the first to inject forecast errors into MRP lot-sizing research. As such it attempts to deal with one of the major objections against the practical relevance of previous research in this area.     

Morality and Nuclear Energy: Perceptions of Risks and Benefits,Personal Norms,and Willingness to Take Action Related to Nuclear Energy

We examined factors underlying people's willingness to take action in favor of or against nuclear energy from a moral perspective. We conducted a questionnaire study among a sample of the Dutch population (N = 123). As expected, perceptions of risks and benefits were related to personal norms (PN), that is, feelings of moral obligation toward taking action in favor of or against nuclear energy. In turn, PN predicted willingness to take action. Furthermore, PN mediated the relationships between perceptions of risk and benefits and willingness to take action. In line with our hypothesis, beliefs about the risks and benefits of nuclear energy were less powerful in explaining PN for supporters compared to PN of opponents. Also, beliefs on risks and benefits and PN explained significantly more variance in willingness to take action of opponents than of supporters. Our results suggest that a moral framework is useful to explain willingness to take action in favor of and against nuclear energy, and that people are more likely to protest in favor of or against nuclear energy when PN are strong.

What's Playing in the Organizational Theater? Collusive Relationships in Management

This article takes as its point of departureconcepts derived from couple therapy to betterunderstand collusive relationships in organizations. Aswe examine these dysfunctional workplace relationships— these interpersonal gridlocks —four main types of collusive superior subordinateinteraction patterns are identified — thenarcissistic, the controlling, the paranoid, and thesadomasochistic — and the consequences of each such dyad in organizationsare explored. In conclusion, the paper presents a numberof recommendations on how to recognize the presence ofsuch collusive arrangements (taking leadership behavior as a point of departure) and suggestspreventive steps that can be taken.

Ergonomic recommendations and their role in cardiac sonography

Musculoskeletal disorders (MSDs) have been recognized as a serious hazard to the health and safety of sonographers. Recommendations have been made on ways to reduce and prevent the frequency and severity of these disorders. The purpose of this study was to ascertain the impact ergonomics has had on the prevalence of MSDs among cardiac sonographers. Three hundred randomly selected Registered Diagnostic Cardiac Sonographers were surveyed. Eighty-one respondents completed the survey. The majority of the sample population was female with an average age of 40 and job tenure between 6-15 years. Ninety percent of respondents reported musculoskeletal pain/discomfort while scanning. Seventy-three percent of respondents perceived a need for ergonomic interventions. The majority of respondents were aware of previously recommended ergonomic interventions and had implemented what was feasible. Still, the experience of pain and discomfort, and incidence of MSDs remains exceptionally high for this occupation. It appears that recommended ergonomic interventions have not had a significant impact on improving the health and safety of cardiac sonographers.
