Teachers’ social support,somatic complaints and academic motivation in children and early adolescents

The study aim was to find out what is pupils perception of teachers' support and to check if different types of perceived support are connected with the level of somatic symptoms reported by students at school. Additionally the study searched for possible links between students' evaluation of teachers ‘as instructors, guides and caregivers’ and their motivation to attend the class and to study the subject. The results show that students perceived informative teachers' support as the most available. Prevalent somatic symptoms reported by students were those connected with tiredness, distraction, low energy and pain. Teachers' evaluation was positively linked to academic motivation. High level of perceived (1) emotional, (2) informational teachers support and a (3) high ‘mark’ prescribed by student to the teacher via teachers' evaluation were negatively related to somatic symptoms. Due to students composition i.e. children originating from different economic backgrounds, the support perception from this perspective was also analysed. The study results indicate that teachers' support perception by children living in harsh economic conditions depended on the division in which they attend the school.     

Local Change

An agent can usually hold a very large number of beliefs. However, only a small part of these beliefs is used at a time. Efficient operations for belief change should affect the beliefs of the agent locally, that is, the changes should be performed only in the relevant part of the belief state. In this paper we define a local consequence operator that only considers the relevant part of a belief base. This operator is used to define local versions of the operations for belief change. Representation theorems are given for the local operators.     

Na+,K(+)-ATPase activity is reduced in hippocampus of rats submitted to an experimental model of depression: effect of chronic lithium treatment and possible involvement in learning deficits

This study was undertaken to verify the effects of chronic stress and lithium treatments on the hippocampal Na+,K(+)-ATPase activity of rats, as well as to investigate the effects of stress interruption and post-stress lithium treatment on this enzyme activity and on spatial memory. Two experiments were carried out; in the first experiment, adult male Wistar rats were divided into two groups: control and submitted to a chronic variate stress paradigm, and subdivided into treated or not with LiCl. After 40 days of treatment, rats were killed, and Na+,K(+)-ATPase activity was determined. In the second experiment, rats were stressed during 40 days, and their performance was evaluated in the Water Maze task. The stressed group was then subdivided into four groups, with continued or interrupted stress treatment and treated or not with lithium for 30 additional days. After a second evaluation of performance in the Water Maze, rats were killed and Na+,K(+)-ATPase activity was also measured. Results showed an impairment in Na+,K(+)-ATPase activity and in Water Maze performance of chronically stressed rats, which were prevented by lithium treatment and reversed by lithium treatment and by stress interruption. These results suggest that the modulation of Na+,K(+)-ATPase activity may be one of the mechanisms of action of lithium in the treatment of mood disorders.     

Recharging cognition with DC brain polarization

Electrical direct current (DC) has been applied to the human head throughout history for various reasons and with claims of behavioral effects and clinical benefits. This technique has recently been rediscovered and its effects validated with modern quantitative techniques and experimental designs. Despite the very weak current used, DC polarization applied to specific brain areas can alter verbal fluency, motor learning and perceptual thresholds, and can be used in conjunction with transcranial magnetic stimulation. Compact and safe, this old technique seems poised to allow major advances cognitive science and therapy.     

The Amish: Perceptions of genetic disorders and services

Previous studies of the closed Amish population have proven to be valuable in the field of genetics, however they have not explored the Amish parents' opinions and attitudes concerning genetic conditions and services. This exploration is necessary in order to provide culturally sensitive health care to a population at an increased risk for certain genetic conditions. The purpose of the present study was to examine the Amish population's general knowledge of genetic disorders, services, and the terminology used in describing inherited conditions, as well as their attitudes toward medical care and ethical and reproductive issues. Information was obtained from 17 Amish families, 12 who had an incidence of a genetic condition and five who had one or more children with other special health care needs, during personal interviews conducted in their homes in Lancaster, Pennsylvania. Results of the interviews showed that the birth of an affected child did not deter subsequent reproduction, that the majority of the parents were never offered genetic counseling or prenatal testing, and that the parents are interested in understanding the cause of their children's problems and recurrence risks.

The Impact of Christianity on Therapy with Latino Families

Unquestioned patriarchal beliefs prescribed by religion often place women and racial and sexual minorities in positions of victimization. In the therapeutic framework, “God” represents unquestioned values that must be challenged and evaluated in order to have a transformative effect. As a result of the increase in the number of Latino immigrants to the United States, it is inevitable for therapists to work with Latino families, a highly religious population. The purpose of this paper is to explore, through a feminist perspective, the role of Christianity and the feminist movement in Latin America and the impact of Christianity on therapists’ work with Latino families.     

A Model of Voluntary Turnover in Male Canadian Forces Recruits

This study of voluntary turnover was conducted on Canadian Forces (CF) recruits (N = 459) undergoing basic military training. In response to growing voluntary attrition concerns, a model of early voluntary turnover was tested. The model included pre-entry individual characteristics (pre-entry normative commitment, desire for military career, and mental toughness), postentry work attitudes and intentions (normative CF commitment, affective commitment, and turnover intentions), and actual turnover behavior. Ten of the 13 specified paths were supported, and the model yielded an overall good fit, providing empirical evidence for the influence of pre-entry characteristics on the development of commitment and subsequent turnover.     

Personality and occupational markers of ‘solid citizenship’ are associated with having fewer children

Investigating associations between personality and reproductive fitness may reveal the adaptive significance of human behavioural traits. What we dub ‘solid-citizenship’ personality characteristics such as self-control, diligence and responsibility may repay study from an evolutionary perspective as they protect against negative life-outcomes. We explored associations between reproductive fitness and personality questionnaire markers of solid citizenship in 4981 women from four Australian samples. We also examined relations between reproductive fitness and army discharge status, an applied measure of solid citizenship, in 15,283 Vietnam War-era military veterans. In two Australian samples there were significant negative associations between reproductive fitness and personality measures of solid citizenship. Similarly, in the US study honourably discharged servicemen on average fathered significantly fewer children than non-honourably discharged servicemen. Since personality is genetically influenced, our results suggest that genetic variants for solid citizenship may be decreasing in frequency in some populations, in line with other modern findings but in contrast to historical analyses. Causes for this change may include relatively more conscientious women using contraception to prioritise their careers over reproduction and the availability of systematic welfare provisioning.
