Urban–Rural Variation in Satisfaction with Life: Demographic, Health, and Geographic Predictors in Halifax, Canada

This paper examines how satisfaction with life (SWL) varies in four zones of the urban–rural continuum, for 1,971 residents of the county-sized municipality of Halifax, Nova Scotia, Canada. It also examines whether the predictors of SWL themselves vary by rural–urban. Data are from the STAR project, which is an innovative GPS-assisted time diary survey. ‘Global’ SWL varies significantly by urban–rural zones, being highest in the inner city (IC), and lowest in the outer commuter belt (OCB). Self-rated health is a significant bivariate correlate, as are age, whether married, household size, and household income (all of which vary significantly by U-R zones). Several geographic variables co-vary significantly with SWL, particularly community belonging (strong in IC, weak in OCB), unsafe after dark (worst in IC, best in OCB), and commuting time (least in IC, most in OCB). A regional multivariate model yielded significant predictors related to physical health, mental health, and community geography, but excluded socio-demographic variables. Separate models for each urban–rural zone showed that SWL is more predictable at the zonal level than for the region as a whole, and the predictors vary considerably by zone. Physical health is an important predictor in the inner city and suburbs, unsafe after dark is significant only in the suburbs, and travel-related variables are very important in the inner commuter belt.     

Is there an age-related positivity effect in visual attention? A comparison of two methodologies

Research suggests a positivity effect in older adults' memory for emotional material, but the evidence from the attentional domain is mixed. The present study combined 2 methodologies for studying preferences in visual attention, eye tracking, and dot-probe, as younger and older adults viewed synthetic emotional faces. Eye tracking most consistently revealed a positivity effect in older adults' attention, so that older adults showed preferential looking toward happy faces and away from sad faces. Dot-probe results were less robust, but in the same direction. Methodological and theoretical implications for the study of socioemotional aging are discussed.     

Indecent medicine: in defense of the absolute prohibition against physician participation in torture

In a recent article, Gross (2004) argues that physicians in decent societies have a civic duty to aid in the torturing of suspected terrorists during emergency conditions. The argument presupposes a communitarian society in which considerations of common good override questions of individual rights, but it is also utilitarian. In the event that there is a ticking bomb and no other alternative available for defusing it, torture must be used, and physicians must play their part. In an earlier article, Jones (1980) also argues in favour of physician participation in torture, going so far as to enthusiastically endorse the allocation of research resources as well to ensure that the ability to meet emergency situations is as efficient as scientifically possible. I argue against both these views and defend the absolute prohibition against torture generally, and against any participation by physicians in particular. I show that these arguments are incompatible with liberal or decent societies, and that the institutional requirements for making torture effective would constitute an unacceptable degradation both of medical ethics and practice, as well as of political institutions in general.     

Subliminal perception and its cognates: theory, indeterminacy, and time

Unconscious processes, by whatever name they may be known (e.g., "subliminal," "implicit"), are invariably operationalized by the dissociation paradigm, any situation involving the dissociation between two indicators (or sets of indicators), one of availability (epsilon) and the other, of accessibility (alpha), such that, epsilon>alpha. Subliminal perception has been traditionally defined by a special case of the dissociation paradigm in which availability exceeds accessibility when accessibility is null (epsilon>alpha/alpha=0). Construct validity issues bedevil all dissociation paradigms since it is not clear what might constitute appropriate indicators that, moreover, are pure and exhaustive. Semantic and theoretic drifts in the recent literature--e.g., the confusion of different versions of the dissociation paradigm, the equation of conscious-unconscious with direct-indirect tests, and the foisting of the criterion of qualitative differences--have tended to undermine emerging theoretic parsimony. On the other hand, a crucial factor has been left out of theory development: time. Both epsilon and alpha can rise and fall over time, often asynchronously, and so dissociations may wax and wane and, even, reverse over time. Some laboratory evidence suggests that accessibility measures (e.g., d'), as they approach chance, may actually dip below chance (subchance perception). If so, d'=0 (the chance-limen or objective threshold), could be an averaging artifact of positive and negative d's. Conscious accessibility is not either-or but more or less, and variable over time.     

Race/ethnicity and sexual orientation: intersecting identities

Racial/ethnic minority women who come to identify as lesbian must confront the norms and expectations of both the majority and minority cultures in which they live. This article reports findings from a diverse sample of nearly 450 women and examines the effects of race/ethnicity on sexual identity development in African American, Latina, and White lesbians. African American and Latina respondents differed little in the timing and disclosure of lesbian identity; comparisons between women of color and White women revealed substantial variability. Findings are discussed in terms of their implications for practice with lesbians of color.     

Natural Deduction for Non-Classical Logics

We present a framework for machine implementation of families of non-classical logics with Kripke-style semantics. We decompose a logic into two interacting parts, each a natural deduction system: a base logic of labelled formulae, and a theory of labels characterizing the properties of the Kripke models. By appropriate combinations we capture both partial and complete fragments of large families of non-classical logics such as modal, relevance, and intuitionistic logics. Our approach is modular and supports uniform proofs of soundness, completeness and proof normalization. We have implemented our work in the Isabelle Logical Framework.     

Concurrent validity of Holland's theory for non-college-degreed working women

This study, using the Vocational Preference Inventory (VPI) and the Self-Directed Search (SDS), explored the concurrent validity of Holland's theory for employed non-college-degreed women. The VPI and SDS were administered to 114 women workers in occupational environments consistent with Holland's vocational environments. The results revealed that three scales of the VPI and five scales of the SDS successfully differentiated the occupational groups consistent with Holland's theoretical notions. In general, the findings lend some support to the concurrent validity of Holland's theory for employed non-college-degreed women.
