A Two-Dimensional Theory of Health

The starting point for the contemporary debate about theories of health should be the holistic theory of Lennart Nordenfelt, claims George Khushf, not the refuted theory of Christopher Boorse. The present paper is an attempt to challenge Nordenfelt and to present an alternative theory to his and other theories, including Boorse’s. The main problems with Nordenfelt’s theory are that it is relativistic, that it leads to counter-intuitive results as to what goals can count as healthy, that it focuses on the wrong kind of abilities, that it makes measuring health extra difficult, and that it does not give us a sufficient account of health, at most a necessary one. The alternative theory proposed is two-dimensional. First, health is to have developed the abilities and dispositions that members of one’s culture typically develop, and be able to use them, in acceptable circumstances; and second, health is to experience positive moods and sensations, the kinds that have internal causes. The theory solves the problems attached to Nordenfelt’s theory by not being individual relativistic, by eliminating the goals in the definition, by giving an alternative interpretation of “ability,” by making health easier to measure, and by adding the dimension of well-being that, together with health as ability, not only gives us a necessary, but also a sufficient, account of health.     

The self-protective and undermining effects of attributional ambiguity

Two experiments assessed the self-protective and undermining effects of attributional ambiguity. Both studies utilized immersive virtual environment technology to achieve otherwise difficult manipulations of stigma. In Experiment 1, White and Latino participants were either stigmatized (represented as Latino) or not (represented as White) and given negative leadership performance feedback. Afterwards, stigmatized participants reported higher well-being and attributed negative feedback more to discrimination than nonstigmatized participants. In Experiment 2, Latinos represented veridically showed self-protective effects after receiving negative leadership feedback. Additionally, this experiment revealed undermining effects of attributional ambiguity such that those participants represented as Latino discounted positive feedback and reported lower well-being. Thus, attributional ambiguity of stigmatized individuals (real or induced) buffered well-being in the face of negative feedback but undermined the well-being effects of positive feedback.     

Middle school student perceptions of school climate: Examining protective functions on subsequent adjustment problems

The present study examined the roles of student perceptions of four aspects of school climate (friction, cohesion, competition among students, and satisfaction with classes) as moderators of the relations between effortful control and subsequent conduct problems and depressive symptoms. Participants were 488 10-to-14-year old students involved in two waves, with one year between each wave, of a study. Hierarchical regression analyses indicated that high levels of perceived friction predicted more subsequent conduct problems and depressive symptoms, even after baseline levels of these problems were partialled out. Low levels of effortful control also elevated risk for subsequent conduct problems. However, perceptions of the school as high in cohesion offset the risk associated with low levels of effortful control. Perceived satisfaction with classes also offset this risk, but only for females. Contrary to expectations, student perceptions of school climate did not interact with effortful control to predict subsequent depressive symptoms.     

Neighborhood Violence and Coparent Conflict: Interactive Influence on Child Psychosocial Adjustment

The interactive influence of neighborhood violence and coparent conflict on child psychosocial adjustment was examined in a sample of 117 low-income, inner-city African American families. Data were collected and analyzed cross-sectionally and longitudinally. Lower levels of coparent conflict buffered girls, but not boys, from the detrimental effects of living in neighborhoods characterized by high levels of violence. In both cross-sectional and longitudinal analyses, lower levels of coparent conflict, relative to higher levels, protected girls from depressive symptoms and aggressive behaviors in the context of higher levels of neighborhood violence. Clinical implications of the findings and directions for future research are discussed.     

A case study of community-based participatory research ethics: The healthy public housing initiative

We conducted and analyzed qualitative interviews with 12 persons working on the Healthy Public Housing Initiative in Boston, Massachusetts in 2001. Our goal was to generate ideas and themes related to the ethics of the community-based participatory research in which they were engaged. Specifically, we wanted to see if we found themes that differed from conventional research that is based on an individualistic ethics. There were clearly distinct ethical issues raised with respect to projects and individuals who engage in community-based collaborations. The differences that arose from the interviews were seeking equality between the partners, the need for the community partner to defend the community, dealing with unflattering data, meeting community expectations and producing tangible benefits to the community.

The K-9 Unit

Abstract

This paper describes the process of evaluating and designing interventions for sensory processing preferences using the Adult Sensory Profile. The measure is theoretically based on Dunn's Model of Sensory Processing (1997) which describes the intersection of neurological threshold and behavioral responses resulting in the following four quadrants: sensory sensitivity, sensation avoiding, low registration and sensation seeking. The compatibility of this model and recovery is discussed along with specific strategies for matching environments and sensory processing preferences.     

The Performance of Environmental Science in Research Teams

Scientists' practices rely not only on the discursive production of science but also on routine interactions whereby scientists manage their teams and their publics. The metaphor of the theatre helps explain how researchers perform impressions to different audiences. This metaphor can also help analyse how scientists and researchers cooperate in performance teams in order to manage credibility impressions. How are research teams constructed and maintained? How do team members respond to the challenges of coordinating the team and elaborating a common vision given their differences in aims and understandings? From 2005 to 2007 a scientific team worked together in the city of Tuzla, Bosnia and Herzegovina, to develop land remediation measures for coal waste disposal sites. The team was organised around a common front developed through ongoing negotiation and bargaining. Scientists employed different strategies to maintain the team through the development of the project, such as reciprocity, unanimity and bargaining. To accommodate individual views, the common front emphasised the presentation of results and the process of research over its specific content and impact.     

Evolution,green beards,and skin hue wage discrimination

This paper provides an evolutionary rationale for both interracial and intraracial wage differentials by examining the implications of white employers mediating their employer‐employee relationships on the basis of genetic similarity. If in organized labor markets; relationships mediated through genetic similarity are optimal in terms of Darwinian fitness, a fundamental evolutionary implication is that the Marginal Rate of Substitution (MRS) in Darwinian fitness holding extended fitness constant equals the MRS in preferences holding utility constant. Given such an evolutionary equilibrium, results are derived showing that the strength of tastes for discrimination depends upon the skin hue of non‐white workers. The rationale established for racial wage differentials is that where skin hue serves to indicate genetic similarity between employer and employee, wage differentials emerge that are a function of skin hue.     

Early family context and development of adolescent ruminative style: Moderation by temperament

We know very little about the development of rumination, the tendency to passively brood about negative feelings. Because rumination is a risk factor for many forms of psychopathology, especially depression, such knowledge could prove important for preventing negative mental health outcomes in youth. This study examined developmental origins of rumination in a longitudinal sample (N=337; 51% girls) studied in preschool (ages 3½ and 4½ years) and early adolescence (ages 13 and 15 years). Results indicated that family context and child temperament, assessed during the preschool period, were risk factors for a ruminative style in adolescence. Specifically, early family contexts characterised by over-controlling parenting and a family style of negative-submissive expressivity predicted higher levels of later rumination. These associations were moderated by children's temperamental characteristics of negative affect and effortful control. Further, the interaction of these temperament factors exerted an additional influence on later rumination. Implications for prevention and intervention efforts are discussed.
