Modeling Cyclical Patterns in Daily College Drinking Data with Many Zeroes

Daily college drinking data often have highly skewed distributions with many zeroes and a rising and falling pattern of use across the week. Alcohol researchers have typically relied on statistical models with dummy variables for either the weekend or all days of the week to handle weekly patterns of use. However, weekend versus weekday categorizations may be too simplistic and saturated dummy variable models too unwieldy, particularly when covariates of weekly patterns are included. In the present study we evaluate the feasibility of cyclical (sine and cosine) covariates in a multilevel hurdle count model for evaluating daily college alcohol use data. Results showed that the cyclical parameterization provided a more parsimonious approach than multiple dummy variables. The number of drinks when drinking had a smoothly rising and falling pattern that was reasonably approximated by cyclical terms, but a saturated set of dummy variables was a better model for the probability of any drinking. Combining cyclical terms and multilevel hurdle models is a useful addition to the data analyst toolkit when modeling longitudinal drinking with high zero counts. However, drinking patterns were not perfectly sinusoidal in the current application, highlighting the need to consider multiple models and carefully evaluate model fit.     

Whom do children copy? Model-based biases in social learning

This review investigates the presence of young children’s model-based cultural transmission biases in social learning, arguing that such biases are adaptive and flexible. Section 1 offers five propositions regarding the presence and direction of model-based transmission biases in young children’s copying of a model. Section 2 discusses the cognitive abilities required for differing model-based biases and tracks their development in early childhood. Section 3 suggests future areas of research including considering the social aspect of model-based biases and understanding their use within a comparative perspective.     

Capital Possession: a comparative approach to 'New Age' and control of the means of possession

This paper reconsiders academic representations of religious phenomena that have been called New Age through contextualised comparison of social practice and discourse. This challenges both the replication of emic models of a New Age in terms that are abstract, classed and racialised, and the way in which the New Age is represented as a social phenomenon unrelated to other contemporary religious forms throughout the world. By identifying spirit possession as a central practice within what is called ‘non-formative religion’, comparisons are drawn with Pentecostalism and Shamanism, documenting their growth under common conditions of neoliberal globalisation across the world. To examine reasons for such resurgence, attention is drawn to what is called the ‘means of possession’: the social contexts in which possession occurs and is controlled. The ambiguity by which control of the means of possession is exercised is explored in terms of a broader social context in which self-authority is both denied and demanded.     

Defining the Chaperone's Role as Escort,Educator or Parent

ABSTRACT

What is the cognitive and emotional nature of fascination? Drawing on theories of cognitive and emotional interest, we explored the nature of visitor fascination (i.e., intense interest) at two High North museums in Norway. In Study 1, we found interesting and informative patterns related to which museum displays 20 teenage visitors experienced as particularly fascinating and why, along with the cognitive and affective qualities associated with those fascinations. We pursued these findings in more detail with 60 new visitors in Study 2. Through path modeling we were then able to capture the dynamics of when each of the following variables mattered to museum display experiences and in what ways: (1) display-relevant prior knowledge and interest, (2) the cognitive accessibility and emotional pleasure of museum display experiences, and (3) cognitive and affective interest outcomes. Implications for theories of interest and future research for exhibit design are discussed.     

The specific needs of foreign national prisoners and the threat to their mental health from being imprisoned in a foreign country

Foreign national prisoners represent an increasingly significant and vulnerable proportion of the prison estate in England and Wales, accounting for 13% of the population in custody (Prison Reform Trust, 2010). They are ever present in the Safer Custody statistics, accounting for nearly a quarter of self-harm incidents and self-inflicted deaths (HM Inspectorate of Prisons, 2009). Recent HM Inspectorate of Prisons, 2006, HM Inspectorate of Prisons, 2007, HM Inspectorate of Prisons, 2010 and a handful of research studies outline the lack of support facing many foreign national prisoners, in terms of language problems, social and cultural isolation, family support, immigration uncertainties and diversity issues. This paper reviews the current context of the foreign national prisoner population in England and Wales, paying particular attention to their experiences, specific needs, and potential threat to their mental health from being imprisoned in a foreign country. We then offer suggestions as to how these issues can be addressed by reviewing existing initiatives and making recommendations for future research.     

Frontolimbic neural circuitry at 6 months predicts individual differences in joint attention at 9 months

Elucidating the neural basis of joint attention in infancy promises to yield important insights into the development of language and social cognition, and directly informs developmental models of autism. We describe a new method for evaluating responding to joint attention performance in infancy that highlights the 9‐ to 10‐month period as a time interval of maximal individual differences. We then demonstrate that fractional anisotropy in the right uncinate fasciculus, a white matter fiber bundle connecting the amygdala to the ventral‐medial prefrontal cortex and anterior temporal pole, measured in 6‐month‐olds predicts individual differences in responding to joint attention at 9 months of age. The white matter microstructure of the right uncinate was not related to receptive language ability at 9 months. These findings suggest that the development of core nonverbal social communication skills in infancy is largely supported by preceding developments within right lateralized frontotemporal brain systems.     

Strategies of influence in close relationships

In this study, we examined how close relationship partners spontaneously influence each other while they discussed an existing problem in their relationship. According to theories of social influence, people in important, self-defining relationships should experience the relationship itself as a potent source of influence. Thus, they are likely to rely on the relationship as a source of power and to use influence strategies that reference relationship norms and values. Consistent with this reasoning, dating partners who were subjectively closer to their partners/relationships were more likely to reference the relationship in their influence attempts than those who were less subjectively close. Furthermore, referencing the relationship was an effective influence strategy. Greater referencing was associated with opinion shifts during discussions for both agents and targets of influence, with each compromising toward the other's position. In contrast, greater use of negative coercion as an influence strategy (e.g., derogation of the partner or punishment) was associated with less compromise.     

Adolescents who need help the most are the least likely to seek it: the relationship between low emotional competence and low intention to seek help

It has been found that university students who were the least skilled at managing their emotions also had the lowest intention of seeking help from a variety of nonprofessional sources (e.g. family and friends). The present study sought to extend these findings by focusing on adolescents, examining a larger number of emotional competencies, and exploring the possibility that social support explains the relationship between emotional competence and help-seeking. A total of 137 adolescents (aged 16-18) completed an anonymous survey that assessed social support, emotional competencies, and intention to seek help from a variety of professional and nonprofessional sources. As expected, adolescents who were low in emotional awareness, and who were poor at identifying, describing, and managing their emotions, were the least likely to seek help from nonprofessional sources and had the highest intention of refusing help from everyone. However, low emotional competence was not related to intention to seek help from professional sources (e.g. mental health professionals). The significant results involving nonprofessional sources were only partially explained by social support, suggesting that even adolescents who had high quality support were less likely to make use of that support if they were low in emotional competence.     

The effects of feedback format on dynamic decision making

The tendency for people to perform poorly on dynamic decision-making tasks has been attributed to their inability to form adequate mental models of dynamic systems (Sterman, 1994). An alternative explanation is that the tabular feedback formats used in previous studies do not facilitate mental representations of the dynamic task and lead to processing overload. Drawing on research in the human factors area, this study examined the impact of graphical versus tabular feedback formats on performance, response times, and learning on a dynamic inventory control task under differing levels of complexity. The graphical feedback group performed better but the tabular group showed stronger evidence of learning. The two groups did not differ in response times. Records of decision rationales showed that participants were aware of complexity factors but were unable to cope with them effectively under either feedback format. The proximity compatibility principle ( Wickens & Carswell, 1995) from human factors, which argues that feedback must be matched to the processing requirements of the task, provides a useful theoretical framework for the design and testing of feedback formats for organizational tasks and criteria.     

Mandated Supervision: An Intervention for Disciplined Professionals

Mandated supervision with disciplined mental health professionals is defined and discussed. In the absence of empirical support for supervision in this context, sources of theoretical support are provided. Risks, benefits, and implications for practice for supervisors are also discussed.
