Distress after a single violent crime: how shame-proneness and event-related shame work together as risk factors for post-victimization symptoms

To increase understanding of post-victimization symptom development, the present study investigated the role of shame- and guilt-proneness and event-related shame and guilt as potential risk factors. 35 individuals (M age = 31.7 yr.; 48.5% women), recently victimized by a single event of severe violent crime, were assessed regarding shame- and guilt-proneness, event-related shame and guilt, and post-victimization symptoms. The mediating role of event-related shame was investigated with structural equation modeling (SEM), using bootstrapping. The guilt measures were unrelated to each other and to post-victimization symptoms. The shame measures were highly intercorrelated and were both positively correlated to more severe post-victimization symptom levels. Event-related shame as mediator between shame-proneness and post-victimization symptoms was demonstrated by prevalent significant indirect effects. Both shame measures are potent risk factors for distress after victimization, whereby part of the effect of shame-proneness on post-victimization symptoms is explained by event-related shame.     

Timing is essential for rapid effects of corticosterone on synaptic potentiation in the mouse hippocampus

Stress facilitates memory formation, but only when the stressor is closely linked to the learning context. These effects are, at least in part, mediated by corticosteroid hormones. Here we demonstrate that corticosterone rapidly facilitates synaptic potentiation in the mouse hippocampal CA1 area when high levels of the hormone and high-frequency stimulation coincide in time, but not when corticosterone is given either before or after repetitive stimulation. This effect could not be blocked by antagonists of the mineralocorticoid receptor and glucocorticoid receptor (spironolactone and RU 38486, respectively). These data provide a biological substrate for the important behavioral observation that stress and corticosteroid hormones can facilitate learning and memory processes.     

Personality: a vulnerability factor in rhinitis?

Personality traits were assessed in 63 patients with persistent allergic or non-allergic rhinitis with the Karolinska Scales of Personality, developed with the aim of measuring psychobiological vulnerability factors, and were compared with a reference group comprising a random sample of 400 sex- and age-stratified subjects. The patients' personality profile differed slightly - within one standard deviation - but significantly from the reference group on a number of factors together suggestive of a disinhibitory disposition, an inclination to express anxiety through somatic rather than psychological channels, difficulties in maintaining emotional distance to others, and a limited awareness of aggressive affect, a pattern that suggests that they expose themselves to more stimulation than they can process in terms of thought and feelings, generating sustained physiological arousal that may contribute to the development of their intolerance reactions.

How Lending Officers Construe Assessments of Small and Medium-Sized Enterprise Loan Applications: A Repertory Grid Study

Repertory grid technique and principal component analysis were used to map and analyze how 75 lending officers (LOs) viewed their assessments of small and medium-sized enterprises’ loan applications in one bank and region. A standard set of elements and constructs, derived during pre- and pilot studies, was used. Analysis of individual grids demonstrated that the principal components indicated the existence of similarities in LOs’ construing at an aggregated level. Analysis of the mean grid of all respondents indicated that the LOs were encouraged by the bank's lending strategy and supporting system(s) to perform “procedural lending” with a focus on hard and future-oriented information. At the same time, the LOs deemphasized relationship lending, in particular, personal relationships.     

Why the social sciences are irreducible

Synthese - It is often claimed that the social sciences cannot be reduced to a lower-level individualistic science. The standard argument for this position (usually labelled explanatoryholism) is...     

Active Powers and Passive Powers – Do Causal Interactions Require Both?

Philosophia - Many powers metaphysicians postulate both active and passive powers, understood as distinct kinds of intrinsic causal properties of objects. I argue that the category of passive power...
