Observed maternal responses to adolescent behaviour predict the onset of major depression

Two mechanisms have been proposed regarding relations between parental responses to adolescent affective behaviours and the development of depression: the elicitation of parental negativity and the suppression of parental aggression. This study aimed to investigate the boundary conditions under which these two mechanisms operate in relation to the prospective prediction of Major Depressive Disorder (MDD) onset in adolescence. A community sample of 159 adolescents (aged 11–13 years) with no history of MDD completed a family interaction assessment with their mothers, and were followed-up with a diagnostic interview 2–3 years later. Results showed that onset of MDD was prospectively predicted by the elicitation of maternal aggression in response to adolescent aggression (in girls only) and maternal dysphoria in response to adolescent aggression, as well as the suppression of maternal aggression and dysphoria in response to adolescent dysphoria. Thus, support was obtained for both the elicitation of negativity mechanism in relation to maternal responses to adolescents’ aggressive behaviours, and the suppression of aggression mechanisms in relation to maternal responses to adolescents’ dysphoric behaviours. Mothers’ responses to adolescents’ aggressive and dysphoric behaviours may differentially influence the risk of MDD onset for adolescents over time.     

Vanishing Boundaries: When Teaching About Religion Becomes Spiritual Guidance in the Classroom

Abstract. This article revisits the pedagogical dilemma of maintaining neutrality in the religious studies/theology classroom. I argue that if the boundary between teaching about religion and actually teaching spirituality seems to be vanishing, it is because the boundary was inappropriately constructed in the first place. To the extent that the religious concepts, even when compressed into religious studies categories, inherently inspire personal transformation, how can a boundary exist between the ideas students encounter and the power of those ideas to transform? Spiritual guidance emerges naturally in the academic study of religion, and those of us who teach in the field might as well get used to it. In explaining my position, I draw on my experience as a teaching assistant in Professor Walter Capps's course, “Religion and the Impact of the Vietnam War.” I, then, develop a pragmatic teaching strategy, neutral enthusiasm, which preserves the important neutrality of classroom presentation in religious studies courses, yet recognizes the unavoidable evocative power present in the intellectual territory that is religion. Neutral enthusiasm allows the content to do the work.     

Extinction training regulates neuroadaptive responses to withdrawal from chronic cocaine self-administration

Cocaine produces multiple neuroadaptations with chronic repeated use. Many of these neuroadaptations can be reversed or normalized by extinction training during withdrawal from chronic cocaine self-administration in rats. This article reviews our past and present studies on extinction-induced modulation of the neuroadaptive response to chronic cocaine in the mesolimbic dopamine system, and the role of this modulation in addictive behavior in rats. Extinction training normalizes tyrosine hydroxylase levels in the nucleus accumbens (NAc) shell, an effect that could help ameliorate dysphoria and depression associated with withdrawal from chronic cocaine use. Extinction training also increases levels of GluR1 and GluR2/3 AMPA receptor subunits, while normalizing deficits in NR1 NMDA receptor subunits, in a manner consistent with long-term potentiation of excitatory synapses in the NAc shell. Our results suggest that extinction-induced increases in AMPA and NMDA receptors may restore deficits in cortico-accumbal neurotransmission in the NAc shell and facilitate inhibitory control over cocaine-seeking behavior. Other changes identified by gene expression profiling, including up-regulation in the AMPA receptor aggregating protein Narp, suggest that extinction training induces extensive synaptic reorganization. These studies highlight potential benefits for extinction training procedures in the treatment of drug addiction.     

Perceptions of leader-member exchange: comparison of permanent and temporary employees

This study was done to explore how perceived scores for leader-member exchange varies among temporary employees and permanent employees. Study of 158 subordinates indicated no significant difference between the two member groups.     

A multiple-schedule evaluation of immediate and subsequent effects of fixed-time food presentation on automatically maintained mouthing

The purpose of this study was to evaluate the immediate and subsequent effects of fixed-time (FT) food presentations on mouthing. The effects of FT food presentations were analyzed within a three-component multiple schedule in which baseline conditions were implemented during the first and third components and treatment conditions were implemented during the second component. Results indicated that FT food reduced mouthing and that levels of mouthing during post-FT components were reliably lower than pre-FT components. Behavioral mechanisms responsible for treatment effects are discussed.     

Beyond Dialogue: The Role of Science Within Theology

Abstract : The purpose of this article is to provide background overview and contemporary context for the theme of this issue of Dialog, the role of science within theology. Over the last fifty years, this role has primarily involved dialogue and the drive to mutual understanding. That discussion has now reached a new stage seeking to move beyond dialogue toward what some are referring to as hypothetical consonance. One of the most serious constructive proposals moving beyond dialogue is Creative Mutual Interaction (CMI), proposed by Robert John Russell. The first five ways he discusses in CMI specifically address the role of science in theological reflection. It is argued that these five ways will assist the reader in contextualing the discussion found in the articles in this issue. Elaboration of each way is given, concluding with a constructive theological example of the heuristic use of scientific concepts found in quantum field theory.     

Christianity and Eudaimonia,Luck and Eudaimonism

I argue that Christians have at least two reasons to reject eudaimonism, interpreted as the view that attaining eudaimonia—or happiness—is what fulfills the moral life. First, I contend Christian conceptions of eudaimonia should encompass more than realized moral excellence and its requirements. Second, I claim Christians should construe the love at the heart of their moral life as fully realizable even if it is not evidently reciprocated. Both affirmations contradict eudaimonism by implying that eudaimonia depends on more than fulfilling the moral life—the former by rendering eudaimonia more subject to luck than eudaimonists can allow, the latter by depicting the moral life as less subject to luck than eudaimonists can accept. These affirmations also enable Christians to regard God’s love integral to eudaimonia apart from its role in realizing moral excellence and to deny all inability to attain eudaimonia manifests moral failure.
