Conformity to implicit social pressure: the role of political identity

Although studies have shown that implicit social cues, such as images of watchful eyes, can elicit prosocial behavior, little research to date has examined individual differences in people’s susceptibility to such subtle social cues. For example, individuals with a conservative ideology typically value social conformity, obedience, and adherence to social norms more than liberals. To examine partisan heterogeneity, we analyze data from two large randomized field experiments on voting behavior. Results suggest that the impact of eyespots on voter mobilization is indeed likely driven by political identity, with a significant effect for Republicans but not Independents or Democrats. These findings are consistent with an emerging line of research revealing individual differences in how susceptible humans are to implicit social cues.     

Human Trafficking in Australia: The Challenge of Responding to Suspicious Activities

This paper relates to the Australian government's community awareness campaign, as part of the Action Plan to Eradicate Trafficking in Persons, which was announced in October 2003 in response to evidence of human trafficking in Australia. The authors explore the challenges that are likely to be encountered during the implementation of the campaign using empirical data from two Victorian studies, the first of which explored community awareness of trafficking and the second of which examined Victoria Police and local government's responses to trafficking. We conclude that there are significant barriers to both the community and authorities identifying suspicious activities and acting on reports by community. In addition, institution challenges faced by Victoria police and local government in dealing with referred information appropriately will jeopardise the success of the initiative.     

Joint Modelling of Recurrent Infections and Antibody Response by Bayesian Data Augmentation

Abstract.  A joint dynamic model for the interdependence between infection, immunity and risk of disease is presented. Recurrent latent infections are modelled as realizations from a renewal process and antibody dynamics as a diffusion with a decreasing drift modified by the stimulating effect of the random infections. The augmented submodels are estimated simultaneously in one large Markov chain Monte Carlo algorithm. As an example, we consider the risk of recurrent ear infections when having only partially observed information on bacterial carriage and antibody concentrations.     

Extending reading research with a focus on cultural understanding and research on intercultural communication: an empirical investigation in Argentina

The work presented here is an empirical study of how advanced learners of English as a foreign language in Argentina access and understand the culture-specific dimensions of literary narrative texts. It has three purposes. First, to extend research into reading in a foreign language to take account of the culture-specific content of texts. Second, to extend the focus of research on intercultural communication to include the analysis of reading processes. Finally, to introduce an approach to the analysis of the cultural dimension of the reading process using a new model of levels of cultural understanding. It is argued that cultural understanding goes beyond the quantification of prior knowledge or background knowledge in the form of idea units as evidence of the comprehension process. In this sense, the proposed model succeeds in portraying a more detailed picture of cultural understanding in this setting.     

Parenting Practices and Adolescent Sexual Behavior: A Longitudinal Study

The effects of parental attitudes, practices, and television mediation on adolescent sexual behaviors were investigated in a study of adolescent sexuality and media (N = 887). Confirmatory factor analyses supported an eight‐factor parenting model with television mediation factors as constructs distinct from general parenting practices. Logistic regressions indicated that adolescents reporting greater parental disapproval and limits on viewing at Wave 1 were less likely to initiate oral sex between Waves 1 and 2. Adolescents who reported more sexual communication with parents were more likely to initiate oral sex. Results for vaginal intercourse were similar to those for oral sex. Coviewing was a significant negative predictor of initiation of sexual behavior. Parental attitudes and television mediation can delay potentially risky adolescent sexual behaviors.     

The Role of Beliefs in Sexual Behavior of Adolescents: Development and Validation of an Adolescent Sexual Expectancies Scale

This article reports on the development and psychometric properties of the Adolescent Sexual Expectancies Scale (ASEXS). Data were obtained from three annual longitudinal surveys of youth aged 10–17 at the first administration (N=932 at Wave 3). Confirmatory factor analyses indicated that 4 correlated factors corresponding to Social Risk, Social Benefit, Health Risk, and Pleasure adequately represented the expectancy items. High alpha coefficients and stability across survey waves indicated good internal and test–retest reliability for these factors. Latent variable autoregressive analyses indicated that Social Risk expectancies predicted changes in sexual behavior over the course of the study. Multigroup analyses established that the measurement and predictive models were equivalent for males and females and across age groups. The ASEXS provides researchers with a useful measure for examining adolescents' expectancy beliefs about the consequences of sexual behavior.     

Preventing rural child abuse: progress in spite of cutbacks

Professionals in a rural community started a service delivery program not in spite of, but because of, economic distress, to counteract the increase in child abuse caused by economic depression. Public education is shown to be a necessary tool in the establishment of new services.     

Solution of a single stage machine load planning problem

A subgradient algorithm and a binary integer assignment algorithm are used in tandem to determine economic run quantities for an injection molding facility. The model considers machine regular time and overtime capability, machine-tool compatibility, storage area capacity, and the economics of lot size decisions. Use of the model in scheduling and alternative facility evaluation are discussed.     

Understanding the relationship between alcohol and sex: Latino and white college students and problematic sexual experiences while drinking

OBJECTIVES: The authors examined whether the relationship between alcohol expectancies and sexual experiences while drinking differed between Latino and white college students. PARTICIPANTS: The authors considered students if they were white or Latino, unmarried, aged 18-25 years, reported any drinking, and had at least 1 sexual partner in the present school year. METHODS: The investigators collected surveys from a random sample of 13,868 undergraduate students from the 14 California public university campuses. They used tests of group differences and hierarchical multiple regressions. RESULTS: Social-facilitation alcohol expectancies were associated with the total number of different alcohol-related sexual experiences among Latino students. Neither social facilitation nor sexual-enhancement alcohol expectancies were differentially predictive of white or Latino students' frequency of sexual experiences. CONCLUSIONS: Additional research is necessary to determine whether concepts targeted by alcohol prevention programs operate in a differential manner for Latino students.     

Ubiquitous technologies, cultural logics and paternalism in industrial workplaces

Ubiquitous computing is a new kind of computing where devices enhance everyday artefacts and open up previously inaccessible situations for data capture. ‘Technology paternalism’ has been suggested by Spiekermann and Pallas (Poiesis & Praxis: Int J Technol Assess Ethics Sci 4(1):6–18, 2006) as a concept to gauge the social and ethical impact of these new technologies. In this article we explore this concept in the specific setting of UK road maintenance and construction. Drawing on examples from our qualitative fieldwork we suggest that cultural logics such as those reflected in paternalistic health and safety discourse are central in legitimising the introduction of ubiquitous computing technologies. As such, there is little doubt that paternalism plays an essential role in people’s reasoning about ubiquitous computing in this setting. We argue, however, that since discourses such as health and safety are used by everyone (including both managers and workers) in the organisation to further their own aims, technologies transcend purely paternalistic conceptualisations and instead become a focal point for ongoing struggles for control between those deploying and using them. This means that the benefits and costs of such new technologies become harder to define from an ethical and social perspective.
