An Approach to the Study of the Small Group in a Psychiatric Day Hospital

Adults in midlife can be significantly helped through group treatment that is sensitive to the developmental issues of the age period. The author suggests that the developmental crisis of midlife—Generativity versus Stagnation—can, through unconscious processes, become a group crisis as well. A group state of stagnation, enveloping the members as well as the leader, if understood and worked through, can significantly facilitate the developmental progress of its midlife members. A clinical example demonstrates how a therapist helped his midlife group move out of stagnation and toward generativity.     

Social Support and Postdeployment Coping Self-Efficacy as Predictors of Distress Among Combat Veterans

This study evaluated the indirect effect of received social support on distress severity (i.e., posttraumatic stress and depression symptom severity) among 89 combat veterans. Through integrating the social support deterioration deterrence model and the enabling hypothesis, mediating roles of perceived social support and self-efficacy specific to postdeployment adaptation were investigated. Results showed that (a) received social support and perceived social support were not related, and (b) both received and perceived social support indirectly predicted distress severity (posttraumatic stress and depression symptom severity) through postdeployment coping self-efficacy. Specifically, high received and perceived social support independently predicted high postdeployment coping self-efficacy, and high postdeployment coping self-efficacy predicted lower distress severity levels. Theory enhancement and future research needs are discussed.     

Models and fiction

Most scientific models are not physical objects, and this raises important questions. What sort of entity are models, what is truth in a model, and how do we learn about models? In this paper I argue that models share important aspects in common with literary fiction, and that therefore theories of fiction can be brought to bear on these questions. In particular, I argue that the pretence theory as developed by Walton (1990, Mimesis as make-believe: on the foundations of the representational arts. Harvard University Press, Cambridge/MA) has the resources to answer these questions. I introduce this account, outline the answers that it offers, and develop a general picture of scientific modelling based on it.     

Aggressive behavior,related conduct problems,and variation in genes affecting dopamine turnover

A number of dopamine‐related genes have been implicated in the etiology of violent behavior and conduct problems. Of these genes, the ones that code for the enzymes that influence the turnover of dopamine (DA) have received the most attention. In this study, we investigated 12 genetic polymorphisms in four genes involved with DA functioning (COMT, MAOA and MAOB, and DβH) in 179 incarcerated male Russian adolescents and two groups of matched controls: boys without criminal records referred to by their teachers as (a) “troubled‐behavior‐free” boys, n=182; and (b) “troubled‐behavior” boys, n=60. The participants were classified as (1) being incarcerated or not, (2) having the DSM‐IV diagnosis of conduct disorder (CD) or not, and (3) having committed violent or nonviolent crimes (for the incarcerated individuals only). The findings indicate that, although no single genetic variant in any of the four genes differentiated individuals in the investigated groups, various linear combinations (i.e., haplotypes) and nonlinear combinations (i.e., interactions between variants within and across genes) of genetic variants resulted in informative and robust classifications for two of the three groupings. These combinations of genetic variants differentiated individuals in incarceration vs. nonincarcerated and CD vs. no‐CD groups; no informative combinations were established consistently for the grouping by crime within the incarcerated individuals. This study underscores the importance of considering multiple rather than single markers within candidate genes and their additive and interactive combinations, both with themselves and with nongenetic indicators, while attempting to understand the genetic background of such complex behaviors as serious conduct problems.

Who’s Afraid of Nagelian Reduction?

We reconsider the Nagelian theory of reduction and argue that, contrary to a widely held view, it is the right analysis of intertheoretic reduction. The alleged difficulties of the theory either vanish upon closer inspection or turn out to be substantive philosophical questions rather than knock-down arguments.     

The level of frontal-temporal beta-2 band EEG synchronization distinguishes anterior cingulate cortex from other frontal regions

Recent findings indicate that complex cognitive functions are organized at a global level in the brain and rely on large-scale information processing requiring functional integration of multiple disparate neural assemblies. The critical question of the integration of distributed brain activities is whether the essential integrative role can be attributed to a specific structure in the brain or whether this ability is inherent to the cognitive network as a whole. The results of the present study show that mean values of the running correlation function in frontal-temporal EEG pairs with one electrode in the anterior cingulate cortex (ACC) are significantly higher than the same values in other frontal-temporal pairs. These findings indicate a particular role of the ACC in large-scale communication, which could reflect its unique integrative functions in cognitive processing.     

HIV Testing Experience and Risk Behavior Among Sexually Active Black Young Adults: A CBPR-Based Study Using Respondent-Driven Sampling in Durham,North Carolina

African Americans are disproportionately affected by the HIV epidemic inclusive of men who have sex with men, heterosexual men, and women. As part of a community‐based participatory research study we assessed HIV testing experience among sexually active 18–30 year old Black men and women in Durham, NC. Of 508 participants, 173 (74 %) men and 236 (86 %; p = 0.0008) women reported ever being tested. Barriers to testing (e.g., perceived risk and stigma) were the same for men and women, but men fell behind mainly because a primary facilitator of testing—routine screening in clinical settings—was more effective at reaching women. Structural and behavioral risk factors associated with HIV infection were prevalent but did not predict HIV testing experience. Reduced access to health care services for low income Black young adults may exacerbate HIV testing barriers that already exist for men and undermine previous success rates in reaching women.     

Temporalising Tableaux

As a remedy for the bad computational behaviour of first-order temporal logic (FOTL), it has recently been proposed to restrict the application of temporal operators to formulas with at most one free variable thereby obtaining so-called monodic fragments of FOTL. In this paper, we are concerned with constructing tableau algorithms for monodic fragments based on decidable fragments of first-order logic like the two-variable fragment or the guarded fragment. We present a general framework that shows how existing decision procedures for first-order fragments can be used for constructing a tableau algorithm for the corresponding monodic fragment of FOTL. Some example instantiations of the framework are presented.     

Indirect Effects of Parenting Practices on Internalizing Problems among Adolescents: The Role of Expressive Suppression

Negative parenting practices are thought to be essential for the development of adolescents’ internalizing problems. However, mechanisms linking parental practices to adolescents’ internalizing problems remain poorly understood. A potential pathway connecting parental behaviors to internalizing problems could be through adolescent expressive suppression—the tendency to inhibit the observable expression of emotions.This study examined the indirect effects of three individual parenting practices—poor monitoring, inconsistent discipline and use of corporal punishment—on adolescents’ internalizing problems through adolescents’regular use of expressive suppression in a sample of 1132 adolescents (10–14 years). Structural Equation Modeling indicated that parenting practices were related both directly and indirectly to adolescents’ internalizing problems through their relationship with suppression. Clinical implications and future directions are discussed.
