Manipulating Games by Sharing Information

We address the issue of manipulating games through communication. In the specific setting we consider (a variation of Boolean games), we assume there is some set of environment variables, the values of which are not directly accessible to players; the players have their own beliefs about these variables, and make decisions about what actions to perform based on these beliefs. The communication we consider takes the form of (truthful) announcements about the values of some environment variables; the effect of an announcement is the modification of the beliefs of the players who hear the announcement so that they accurately reflect the values of the announced variables. By choosing announcements appropriately, it is possible to perturb the game away from certain outcomes and towards others. We specifically focus on the issue of stabilisation: making announcements that transform a game from having no stable states to one that has stable configurations.     

The Deportation of German Nationals from Canada, 1919 to 1939

This article examines the repatriation of German nationals from Canada between the two World Wars. After World War I, Germans living in Canada were suspicious; this sentiment lingered into the 1930s. During the 1920s, deportations from Canada allowed the government to rid themselves of unwanted residents. During the Great Depression, poor, unemployed immigrants became redundant which encouraged the deportation process. Unfortunately, deportations punished the unlucky and needy; many had experienced hardships in Canada, a country that was unwilling to aid immigrants.     

The self in the couple relationship: part 2

Part 1 of this paper examined some of the ways in which individual therapy, by assisting in the development of a more cohesive sense of self in the individual, inevitably has an impact on the individual's relationships, especially their relationship with a partner. This paper approaches the topic of the significance of ‘the self’ in the couple relationship from an alternative direction. It focuses on the significance of ‘the self’ for couples therapy, and argues that couples therapy may sometimes need to include therapeutic work with one partner to facilitate change in the relationship. In both parts of the paper, a conceptualization of the couple relationship as ‘a transitional space’ is central.     

Accountability and ideology: When left looks right and right looks left

Managers face hard choices between process and outcome systems of accountability in evaluating employees, but little is known about how managers resolve them. Building on the premise that political ideologies serve as uncertainty-reducing heuristics, two studies of working managers show that: (1) conservatives prefer outcome accountability and liberals prefer process accountability in an unspecified policy domain; (2) this split becomes more pronounced in a controversial domain (public schools) in which the foreground value is educational efficiency but reverses direction in a controversial domain (affirmative action) in which the foreground value is demographic equality; (3) managers who discover employees have subverted their preferred system favor tinkering over switching to an alternative system; (4) but bipartisan consensus arises when managers have clear evidence about employee trustworthiness and the tightness of the causal links between employee effort and success. These findings shed light on ideological and contextual factors that shape preferences for accountability systems.     

Regional conferences—A capacity‐building mandate: Report on CRCP2011—Building Bridges and Building a Regional Structure

The Caribbean Regional Conference of Psychology was held in Nassau, The Bahamas, from 15 to 18 November 2011, under the auspices of the International Association of Applied Psychology (IAAP), the International Union of Psychological Science (IUPsyS), and the International Association for Cross‐Cultural Psychology (IACCP). The conference was hosted by the Bahamas Psychological Association, and organized by a committee chaired by Dr Ava Thompson, College of the Bahamas. The CRCP2011 attracted over 400 participants from 37 countries, including 20 nations/territories in the Caribbean. A broad scientific program, organized around six conference themes, addressed strengths and challenges to psychology in the region; the current state of psychological research, assessment, and intervention; historical, cultural, and language influences; and links between Caribbean and global models. Conference outcomes included planning for a series of publications to expand on conference themes and presentations, as well as establishment of a steering group to launch a regional organization to support the science and practice of psychology in the Caribbean.     

Neuropsychological Functioning in Preschool-age Children with Sickle Cell Disease: The Role of Illness-related and Psychosocial Factors

Cognitive and academic deficits have been identified in school-aged children with sickle cell disease (SCD). However, there have been very few identified studies that examine neuropsychological functioning in preschool-age children with SCD. It is important to understand effects of SCD from a developmental perspective and to consider the contribution of environmental factors in this at-risk population. Neuropsychological functioning of preschool-age children with SCD and no history of overt stroke (n = 26) was examined across several domains (language, immediate memory/brief attention, visuospatial/visuoconstructional, motor/visuomotor). The mean Full Scale IQ for the sample was 89.0. Performance on the Immediate Memory/ Brief Attention domain was significantly higher than the other domains, although the pattern of performance was relatively consistent, with mean standard scores ranging from 88.0 to 95.0. Disease severity was not significantly related to cognitive functioning in this group of young children with SCD. Socioeconomic status (SES) was significantly correlated with most domain scores and, based on regression analyses, accounted for 18% to 47% of the variance in functioning. Psychosocial factors, such as number of children living in the home and parental stress levels, were negatively associated with Motor/Visuomotor skills, and weekly hours in school/day care was positively associated with language-related skills. Results suggest that, at this young age, psychosocial risk factors appear to be appropriate targets for intervention, with the goal of improving long-term outcome in children with SCD. Further investigations should include comparison to a matched control group.     

Driftability

In this paper, I argue (contra some recent philosophical work) that an objective distinction between natural selection and drift can be drawn. I draw this distinction by conceiving of drift, in the most fundamental sense, as an individual-level phenomenon. This goes against some other attempts to distinguish selection from drift, which have argued either that drift is a population-level process or that it is a population-level product. Instead of identifying drift with population-level features, the account introduced here can explain these population-level features based on a property that I label driftability. Additionally, this account shows that biology’s “first law”—the Principle of Drift (Brandon, J Phil 102(7):319–335 2006)—is not a foundational law, but is a consequence of driftability.     

Religion and Life Satisfaction Down Under

We investigated the association between religious involvement and life satisfaction using panel data from the 2004, 2007, and 2010 waves of the Household, Income and Labour Dynamics in Australia (HILDA) survey. Our study provides strong evidence of an association between attendance at religious services and life satisfaction in the Australian social context. While social resources mediate this association, there appears to be a remaining direct influence of attendance at religious services on life satisfaction. To unravel this association, there is a need to disentangle and separately assess the influence that ‘religious social resources’ and ‘secular social resources’ may have on life satisfaction.     

Design and Evaluation of a Decision Aid for Inviting Parents to Participate in a Fragile X Newborn Screening Pilot Study

The major objectives of this project were to develop and evaluate a brochure to help parents make an informed decision about participation in a fragile X newborn screening study. We used an iterative development process that drew on principles of Informed Decision Making (IDM), stakeholder input, design expertise, and expert evaluation. A simulation study with 118 women examined response to the brochure. An independent review rated the brochure high on informational content, guidance, and values. Mothers took an average of 6.5 min to read it and scored an average of 91.1 % correct on a knowledge test. Most women rated the brochure as high quality and trustworthy. When asked to make a hypothetical decision about study participation, 61.9 % would agree to screening. Structural equation modeling showed that agreement to screening and decisional confidence were associated with perceived quality and trust in the brochure. Minority and white mothers did not differ in perceptions of quality or trust. We demonstrate the application of IDM in developing a study brochure. The brochure was highly rated by experts and consumers, met high standards for IDM, and achieved stated goals in a simulation study. The IDM provides a model for consent in research disclosing complicated genetic information of uncertain value.
