Psychosocial adjustment to and control of diabetes mellitus: differences by disease type and treatment

The relationship of diabetic patients' psychosocial adjustment to disease type, treatment mode, and indexes of control was examined in a representative community population. The psychometric properties of the Diabetes Educational Profile (DEP) and its application to psychosocial research in diabetes were also investigated. Findings support the reliability and validity of the DEP. Various measures of psychosocial adjustment were related to diabetes control but the specific relationships depended on the particular aspect of adjustment, the specific measure of diabetes control, and the type of disease and treatment. The findings suggest that analyses that aggregate dissimilar patient groups are subject to misinterpretation due to ecological masking and supressor effects. The results indicate that clinicians and researchers must recognize that patients with different disease types and treatment modes have different norms for psychological adjustment and diabetes control. Further, the particular aspects of psychosocial adjustment associated with diabetes control differ across patient groups.     

Preliminary Evidence for Associations of CHRM2 with Substance Use and Disinhibition in Adolescence

Evidence for shared heritable influences across domains of substance use suggests that some genetic variants influence broad risk for externalizing behaviors. Theories of externalizing psychopathology also suggest that genetic liability for substance use manifests as temperamental risk factors, particularly those related to behavioral disinhibition, during adolescence. The cholinergic muscarinic receptor 2 gene (CHRM2) is a promising candidate for studying genetic influences on broad-based risk for externalizing traits. This study examined a candidate CHRM2 polymorphism (rs1455858) in relation to substance use and personality measures of disinhibition in a sample of high-risk adolescents (n?=?124). Bivariate analyses and structural equation modeling (SEM) evaluated associations of rs1455858 with measures of drug involvement (alcohol, tobacco and marijuana) and disinhibition (indexed by impulsivity and sensation seeking scores). Bivariate analyses showed significant associations of CHRM2 with several behavioral phenotypes. In SEM analyses CHRM2 related significantly to latent measures of substance use and disinhibition; additionally, disinhibition mediated the association of CHRM2 with substance use. These results suggest that CHRM2 variants are potentially relevant for adolescent substance use and that temperamental risk factors could contribute to these associations.     

When a Skeptical Hypothesis Is Live

I’m going to argue for a set of restricted skeptical results: roughly put, we don’t know that fire engines are red, we don’t know that we sometimes have pains in our lower backs, we don’t know that John Rawls was kind, and we don’t even know that we believe any of those truths. However, people unfamiliar with philosophy and cognitive science do know all those things. The skeptical argument is traditional in form: here's a skeptical hypothesis; you can’t epistemically neutralize it, you have to be able to neutralize it to know P; so you don’t know P. But the skeptical hypotheses I plug into it are “real, live” scientific‐philosophical hypotheses often thought to be actually true, unlike any of the outrageous traditional skeptical hypotheses (e.g., ‘You’re a brain in a vat’). So I call the resulting skepticism Live Skepticism. Notably, the Live Skeptic's argument goes through even if we adopt the clever anti‐skeptical fixes thought up in recent years such as reliabilism, relevant alternatives theory, contextualism, and the rejection of epistemic closure. Furthermore, the scope of Live Skepticism is bizarre: although we don’t know the simple facts noted above, many of us do know that there are black holes and other amazing facts.     

Development and validation of discriminant functions for the Strong Interest Inventory

This study compared the relative accuracy of (a) single Occupational Scale (OS) scores on the Strong Interest Inventory (SII) and (b) multiple-predictor scoring functions for discriminating members of nine occupations from people-in-general. The functions were constructed using discriminant function analysis with 4797 adults drawn from criterion samples for the 1985 SII. The analyses included Basic Interest Scale (BIS) scores only or combinations of OSs and BISs. Two subsequent analyses, one of which was cross-validation using 1302 young adults with little work experience, also were conducted. Results indicated that BIS-only functions yielded hit rates comparable to single OSs, and functions that combined OSs and BISs generally produced slight improvements in accuracy. These findings are potentially relevant for future SII scale development decisions.     

Beyond Positivist Ecology: Toward an Integrated Ecological Ethics

A post-positivist understanding of ecological science and the call for an “ecological ethic” indicate the need for a radically new approach to evaluating environmental change. The positivist view of science cannot capture the essence of environmental sciences because the recent work of “reflexive” ecological modelers shows that this requires a reconceptualization of the way in which values and ecological models interact in scientific process. Reflexive modelers are ecological modelers who believe it is appropriate for ecologists to examine the motives for their choices in developing models; this self-reflexive approach opens the door to a new way of integrating values into public discourse and to a more comprehensive approach to evaluating ecological change. This reflexive building of ecological models is introduced through the transformative simile of Aldo Leopold, which shows that learning to “think like a mountain” involves a shift in both ecological modeling and in values and responsibility. An adequate, interdisciplinary approach to ecological valuation, requires a re-framing of the evaluation questions in entirely new ways, i.e., a review of the current status of interdisciplinary value theory with respect to ecological values reveals that neither of the widely accepted theories of environmental value—neither economic utilitarianism nor intrinsic value theory (environmental ethics)—provides a foundation for an ecologically sensitive evaluation process. Thus, a new, ecologically sensitive, and more comprehensive approach to evaluating ecological change would include an examination of the metaphors that motivate the models used to describe environmental change.

Internal Realism,Religious Pluralism and Ontology

Internalist pluralism is an attractive and elegant theory. However, there are two apparently powerful objections to this approach that prevent its widespread adoption. According to the first objection, the resulting analysis of religious belief systems is intrinsically atheistic; while according to the second objection, the analysis is unsatisfactory because it allows religious objects simply to be defined into existence. In this article, I demonstrate that an adherent of internalist pluralism can deflect both of these objections, and in the course of so arguing, I deploy a distinction between “conceptual-scheme targetability” and “successful conceptual-scheme targeting”.

Calling and work-related outcomes: Career commitment as a mediator

The current study tested the hypothesis that experiencing a calling to a particular career would relate positively to work-related outcomes, and that these relations would be mediated by career commitment. Using a sample of 370 employees representing diverse occupations at a Western research university, results supported these hypotheses as calling moderately correlated with career commitment, job satisfaction, and organizational commitment and weakly correlated with withdrawal intentions. Career commitment was found to fully mediate the calling–job satisfaction relation, partially mediate the calling–organizational commitment relation, and act as a suppressor in the relation between calling and withdrawal intentions; calling was associated with somewhat greater withdrawal intentions once a person's level of career commitment was taken into consideration. These results suggest that career commitment may represent a critical link between calling and work-related well-being. Implications for research and practice are explored.     

Cognitive load modulates attentional capture by color singletons during effortful visual search

Color singletons that are irrelevant to locating a visual target do not typically capture attention if visual search is effortful. In contrast, when search is efficient color singletons are often found to capture attention. Such distraction by a color singleton can be modulated by single-task vs. dual-task manipulations when visual search is efficient. This is due, presumably, to the increased cognitive load in the dual-task condition, which interferes with top-down attentional control. This study investigated whether capture by a color singleton is also modulated by single-task vs. dual-task manipulations when visual search was effortful. The results of three experiments revealed that attentional capture effects were absent in a single-task condition and were present in a dual-task condition, but only when the identity of the color singleton is not associated with the target response-set. When the identity of the color singleton was relevant to the response-set it captured attention in both the single-task and in dual-task conditions.
