Benefits of physical exercise on executive functions in older people with Parkinson’s disease

The benefits of physical exercise on cognitive functioning have been reported in the literature, but the potential benefits to slow the eventual decline in executive functioning (EF) caused by neurodegeneration from Parkinson’s Disease (PD) have rarely been studied. Thus the objective of this study was to analyze the effects of a multimodal physical exercise program on EF in older people with Parkinson’s disease. The EF of the older people was evaluated by neuropsychological testing, and for confounding variables such as attention, depressive symptoms and anxiety, before and after intervention. The 20 participants were assigned into Control (CG) and Trained (TG) Groups. The TG participated in generalized physical training for 6 months. The ANOVA showed a significant interaction (p < .05) that indicated a beneficial contribution of training on EF. No significant interactions were found in the results for confounding variables between groups and pre- and post-intervention, which supports the beneficial findings of physical exercise training on EF.     

Gesture and metaphor comprehension: Electrophysiological evidence of cross-modal coordination by audiovisual stimulation

In recent years, studies have suggested that gestures influence comprehension of linguistic expressions, for example, eliciting an N400 component in response to a speech/gesture mismatch. In this paper, we investigate the role of gestural information in the understanding of metaphors. Event related potentials (ERPs) were recorded while participants viewed video clips of an actor uttering metaphorical expressions and producing bodily gestures that were congruent or incongruent with the metaphorical meaning of such expressions. This modality of stimuli presentation allows a more ecological approach to meaning integration. When ERPs were calculated using gesture stroke as time-lock event, gesture incongruity with metaphorical expression modulated the amplitude of the N400 and of the late positive complex (LPC). This suggests that gestural and speech information are combined online to make sense of the interlocutor’s linguistic production in an early stage of metaphor comprehension. Our data favor the idea that meaning construction is globally integrative and highly context-sensitive.     

Gender Differences in the Representation of Violence on Spanish Television: Should Women be More Violent?

Gender differences in the representation of aggressors and victims are an important issue in the study of television violence in order to ascertain whether television contributes (and how) to reproduce or transform the traditional gender regime. Eighty-four hours of Spanish main TV broadcasting stations were randomly recorded during years 2000 and 2005. Variables related to the presentation of aggressors and victims and to the normative context of aggression were selected through content analysis. The results show the minimal presence of women in violent scenes. But women are also the victims of more serious violence. Paradoxically, women’s aggressions appear to have more positive consequences and to be less legitimized. The implications of these findings are discussed from a gender studies perspective.     

Combining genetic algorithms and the finite element method to improve steel industrial processes

Most of the times the optimal control of steel industrial processes is a very complicated task because of the elevated number of parameters to adjust. For that reason, in steel plants, engineers must estimate the best values of the operational parameters of processes, and sometimes, it is also necessary to obtain the appropriate model for steel material behaviour. This article deals with three successful experiences gained from genetic algorithms and the finite element method in order to solve engineering optimisation problems. On one hand, a fully automated method for determining the best material behaviour laws is described, and on the other hand we present a common methodology to find the most appropriate settings for two cases of improvement in steel industrial processes. The study of the three reported cases allowed us to show the reliability and effectiveness of combining both techniques.     

An Analysis of Significant Events in Counseling

Using an interview/questionnaire procedure, 19 clients reported 200 helpful, significant events that occurred in ongoing counseling. Each event consisted of one issue presented by the client, the counselor's response to that issue, and the immediate impact the client received from the counselor's response. With the use of qualitative analysis, 9 prominent patterns describing sequences of client change emerged from the data. These patterns were grouped into 3 superclusters of events: Dissonant, Question—Answer, and Congruent. These superclusters and the 9 prominent patterns were used to develop a model for counseling change. Implications for counseling theory and practice are discussed.     

Homeless women and their families: Characteristics,life circumstances,and needs

This study investigated the needs of a sample of 100 women from shelters for the homeless in Richmond, Virginia. The women's responses to a 117-item interview were used to obtain information regarding their domicilary status, work history, educational background, family and health history, social support, reasons for homelessness, and social service needs. The results indicated that a significant number of the women had moved as many as six times within the past five years for various reasons, including domestic violence, interpersonal conflict, overcrowding, and eviction. Many women were high school graduates and had job skills in the health care, educational, and clerical fields. Most women were raised by their natural or extended family and the majority of them had a friend or family member who provided social support. Identified needs included housing, food, clothing, and transportation. The needs of homeless women and their children were different from the needs of the homeless chronically mentally ill and require specialized services as well as an increase in the available number of low-income housing units.

Lack of effects of anabolic-androgenic steroids on locomotor activity in intact male mice

Anabolic-androgenic steroid abusers have reported hyperactivity, euphoria, and decreased fatigue, among other behavioral effects. It has been suggested that the effects of these substances on the central nervous system are similar to those of psychostimulants; however, the influence of steroids on general locomotor activity in laboratory animals is not well understood, especially how noncastrated male rodents are affected. In this study, spontaneous locomotor activity displayed by gonadally intact male mice submitted to several experimental conditions was analyzed. Different housing conditions (individual or cohabiting with a female), diverse steroids (testosterone propionate, nandrolone decanoate, and a mixture of both steroids) and single or repeated injections were employed. At 24 hours after the injection (after the three last injections in the case of chronic treatment) spontaneous locomotor activity was registered on an activity recorder for one 15-min. period. No effects due to the treatment were found in almost every experimental condition. These results contrast with the dramatic decreases in activity described for female mice after treatment with such steroids. It seems that in intact males the steroids' influence on spontaneous locomotor activity may be more subtle than expected. These effects seem very complex depending on duration of treatment and specific situations (spontaneous or forced activity) as well as the interaction with endogenous androgen levels.
