Correlation between Changes in Stress-Induced Corticosterone Secretion and GR mRNA Levels

The current study was conducted to determine the potential relationship between stress-induced corticosterone secretion and corticosteroid receptor mRNA levels after 5 days of intermittent stress. In particular, we were interested in the rate at which animals terminate a stress response, and how this termination may be altered by repeated stress. Adult male Sprague-Dawley rats were subjected to either 5 days of restraint stress or 5 days of an unpredictable stress paradigm. Restraint-stress induced corticosterone secretion was measured on Days 1 and 5 in both groups, and animals were killed on Day 6. Glucocorticoid receptor (GR), and mineralocorticoid (MR) mRNA levels were determined using in-situ hybridization techniques. Five days of restraint stress caused an habituation of the plasma corticosterone response to stress measured 60 and 90 min post-stress initiation; this pattern of corticosterone secretion was not observed in the animals subjected to unpredictable stress. Five days of either stress paradigm did not alter MR mRNA levels measured within the hippocampus or GR mRNA levels within the hippocampus or the medial parvocellular division of the paraventricular nucleus of the hypothalamus (mpPVN). However, an individual's GR mRNA levels measured within the CA1/2 region of the hippocampus and the mpPVN were significantly correlated with the degree of habituation of the corticosterone response to stress measured on Day 5. This suggests that an increase in the rate of termination of the stress response and levels of GR within the hippocampus and mpPVN may be functionally related.     

Action and emotion in everyday life

This study of naturally occurring behaviour employed a "beeper technique" to investigate the actions carried out by 152 subjects in eight different groups, viz. adult students, employed students who were also parents, unemployed, art students, doctoral students, alcoholics, retired people and a control group. Actions were sampled for seven subsequent days, five times per day between 8 a.m. and 10 p.m. at randomly selected occasions. Each action was rated on a number of variables, shortly after it was sampled (median delay approximately 10 min). Some of the findings were: Time allocation corresponded well with national estimates. Being under situational control was highly aversive. Instrumental and consummatory orientations correlated positively. The background variables were, on the whole, only rather weakly related to action ratings, but it was found that women and retired persons tended to report a higher level of well-being.     

Foster Parents’ Knowledge of Child Trauma: An Exploratory Study

To promote trauma-informed professional supports and services to maltreated youth, it is imperative that researchers explore foster parents’ knowledge of child trauma. However, there is a dearth in the literature related to this topic. This exploratory study utilizes a convenience sample (N = 219) of foster parents in one southeastern state. Variables of interest include actual and perceived knowledge about child trauma. After a terse review of background literature, this paper will explicate key results, discuss these findings, and identify salient practice and policy implications derived from this study. The paper will conclude by delineating apposite areas for future research.     

Documentary Bioethics: Visual Narratives for Generations X and Y

Narrative bioethics is primarily understood to involve storytelling through the use of literature. This article suggests that other forms of media are necessary to convey stories of an ethical nature to an audience broader than one being trained as medical professionals. "Documentary bioethics" is a manner to present and interpret stories of an ethical nature using forms of popular electronic media in a reality-based documentary style to society at large, specifically Generations X and Y.     

The Relationships Among Counselor-Trainees' Gender,Cognitive Development,and White Racial Identity: Implications for Counselor Training

In a study of 82 White counselor trainees enrolled in 3 graduate programs, gender and the lowest stage of cognitive development were found to significantly contribute to the variance in lower levels of the White racial identity. Male trainees who tended to think in dichotomous terms and look to authority to provide the correct answers tended to report attitudes about race reflected in lower levels of White racial identity. Significant relationships were not found between higher stages of cognitive development and higher levels of White racial identity. Implications for training are presented and discussed.     

Perceived internal depth in rotating and translating objects

Previous research has indicated that observers use differences between velocities and ratios of velocities to judge the depth within a moving object, although depth cannot in general be determined from these quantities. In four experiments we examined the relative effects of velocity difference and velocity ratio on judged depth within a transparent object that was rotating about a vertical axis and translating horizontally, examined the effects of the velocity difference for pure rotations and pure translations, and examined the effect of the velocity difference for objects that varied in simulated internal depth. Both the velocity difference and the velocity ratio affected judged depth, with difference having the larger effect. The effect of velocity difference was greater for pure rotations than for pure translations. Simulated depth did not affect judged depth unless there was a corresponding change in the projected width of the object. Observers appear to use the velocity difference, the velocity ratio, and the projected width of the object heuristically to judge internal object depth, rather than using image information from which relative depth could potentially be recovered.     

Emotional mortgage

Abstract

Couples who are given property by their parents as a wedding gift or as a gift a little later in the marriage appear to start off their marriages with a bonus that any couple would certainly envy. Often, however, the “given” property has strings attached and the “lucky” couple finds themselves in emotional mortgage to one of their parents. Emotional mortgage is seen as a debt of loyalty and obligation owed to one of the spouse's parents which places the couple in a position of servitude in regard to those parents. The expectation of eventual ownership of property appears to be the mechanism which binds the couple to the parents in the face of countless intrusions and usurpations by the parents.
