“Motivation” and Routine Activities Theory

ABSTRACT

This study examines the motivation aspect of routine activities theory as it pertains to sex offenders. Using logistic regression, data from 163 convicted sex offenders who participated in treatment programs between 1982 and 2000 were analyzed to determine if demographic, abuse histories, sex abuse histories, drug/alcohol use, and other “motivating” variables were predictive of in and out of the home offending. Results indicate abuse and drug use are predictive of home sex offenses while alcohol use is indicative of community offending. While the results and differences were modest, they warrant further exploration of the motivation aspect of routine activities theory.     

Effects of voluntary wheel running on heart rate, body temperature, and locomotor activity in response to acute and repeated stressor exposures in rats

Stress often negatively impacts physical and mental health but it has been suggested that voluntary physical activity may benefit health by reducing some of the effects of stress. The present experiments tested whether voluntary exercise can reduce heart rate, core body temperature and locomotor activity responses to acute (novelty or loud noise) or repeated stress (loud noise). After 6 weeks of running-wheel access, rats exposed to a novel environment had reduced heart rate, core body temperature, and locomotor activity responses compared to rats housed under sedentary conditions. In contrast, none of these measures were different between exercised and sedentary rats following acute 30-min noise exposures, at either 85 or 98 dB. Following 10 weeks of running-wheel access, both groups displayed significant habituation of all these responses to 10 consecutive daily 30-min presentations of 98 dB noise stress. However, the extent of habituation of all three responses was significantly enhanced in exercised compared to sedentary animals on the last exposure to noise. These results suggest that in physically active animals, under some conditions, acute responses to stress exposure may be reduced, and response habituation to repeated stress may be enhanced, which ultimately may reduce the negative and cumulative impact of stress.     

Predicting aggressive collective action based on the efficacy of peaceful and aggressive actions

We examine whether aggressive forms of collective action are predicted by their perceived efficacy and the perceived efficacy of peaceful collective action, and whether the two predictors interact. We present data from surveys examining support for and tendencies toward aggressive collective action among university students who are opposed to increases in tuition fees in Britain (Study 1) and support for suicide bombings against Israeli civilians among Palestinians during the Second Intifada (Study 2). Our results reveal an interaction between the efficacy of peaceful and aggressive collective actions: The more efficacious aggression is perceived to be, the greater its appeal and the less it is assuaged by the efficacy of peaceful action. This implies that (i) people may consider aggressive action whenever it works, even if peaceful action is efficacious, and (ii) people may consider aggressive action even when it seems unpromising, if peaceful action is not efficacious, in an apparent nothing‐to‐lose strategy.     

Comments on so-called "chronic" and "therapy refractory" depression

The problems of so-called "therapy resistant or chronic" depression has been investigated on own patients of the year 1986, but simply one chronic example could be noticed. Configurations-frequence-analytic research didn't essentially result in significant statements. It is referred to that the frequent occurrence of the so-called "therapy resistant" depressions described by some authors, could be in connection with limited diagnosis inventories and insufficient to the personality orientated therapy regime.

Electromyography diagnosis of laryngeal paralysis

The differential diagnosis of laryngeal muscle paralysis can be improved by electromyographical and neurographical analysis. The findings of 30 patients with recurrent paralysis were put forward and compared with the results among 30 test people.     

Acute stress facilitates trace eyeblink conditioning in C57BL/6 male mice and increases the excitability of their CA1 pyramidal neurons

The effects of stress (restraint plus tail shock) on hippocampus-dependent trace eyeblink conditioning and hippocampal excitability were examined in C57BL/6 male mice. The results indicate that the stressor significantly increased the concentration of circulating corticosterone, the amount and rate of learning relative to nonstressed conditioned mice, and the excitability of CA1 hippocampal pyramidal neurons. Behaviorally, there was no effect of the stressor on control mice that received unpaired presentations of the tone and periorbital shock, i.e., neither stressed nor nonstressed control mice showed an increase in conditioned responding that was above baseline levels. Biophysically, the stressor significantly decreased the amplitude of the post-burst afterhyperpolarization (AHP) and decreased spike frequency accommodation relative to cells from nonstressed control mice. The effect was significant for mice that were stressed either 1 h or 24 h earlier. The results suggest that the stressor increases the excitability of hippocampal pyramidal neurons and that the mechanism underlying this increase may contribute to the more rapid acquisition of hippocampally dependent eyeblink conditioning.
