Intrahippocampal insulin improves memory in a passive-avoidance task in male wistar rats

The main impacts of insulin favor the peripheral organs. Although it functions as a neuropeptide, insulin possesses also some central effects. The aim of this study was to determine the effect of intrahippocampal infusion of insulin on passive avoidance learning in healthy male rats. Thirty male wistar rats were divided into three groups (n=10 each). The experimental group had posttraining insulin infusion into the CA1 region of dorsal hippocampus, after which they were compared with sham (saline) and control (intact) groups. Insulin treated animals had greater latency to enter the dark compartment in compare with saline treated (p=0.023) or control groups (p=0.017). Upon our results, we concluded that intrahippocampal injections of insulin may enhance memory for a simple learning task which supports the concept that insulin possibly plays an endogenous role in memory formation.     

Systemic and intrahippocampal administrations of the glucocorticoid receptor antagonist RU38486 impairs fear memory reconsolidation in rats

Reconsolidation is the process by which previously consolidated memories are stabilized after retrieval. Several lines of evidence indicate that glucocorticoids modulate distinct phases of learning and memory. These effects are considered to be mediated by mineralocorticoid receptors and glucocorticoid receptors (GRs), which display a high concentration and distinct distribution in the hippocampus. The role of glucocorticoid system in fear memory reconsolidation is the subject of some controversy. Moreover, we found no studies that assessed the role of hippocampal GRs in fear memory reconsolidation. Here, we investigated the effect of GR blockade on fear memory reconsolidation in rats. Rats were trained and tested in an inhibitory avoidance task. Intrahippocampal or systemic administration of the GR antagonist RU38486 immediately following memory reactivation produced a deficit in post-retrieval long-term memory that persisted over test sessions, and memory did not re-emerge following a footshock reminder. These results indicate that hippocampal GRs are required for reconsolidation of fear-based memory.     

Factor structure of an Arabic translation of the scale, preference for numerical information

An Arabic translation of Viswanathan's 1993 scale, Preference for Numerical Information, was administered to 157 tenth-grade students (M age = 16.1 yr.) in the United Arab Emirates. Analysis showed that the scale was homogeneous as the factor solution was comparable to that reported in the original study and item scores were moderately correlated with total scores when used in a different cultural setting.     

A mathematics content course and teaching efficacy beliefs of undergraduate majors in education

This study was designed to assess the mathematics teaching efficacy beliefs of undergraduates in elementary education through a manipulative-based course in mathematics. Responses of 106 university undergraduates to the 21-item Mathematics Teaching Efficacy Beliefs administered as pre- and posttest without a control group showed a significant immediate postcourse change in their efficacy beliefs using dependent t test.     

Social and Personal Controls and Performance Enhancing Drug Use: Toward an Explanation of Doping Activity among Professional Athletes in Rasht,Iran

The use of performance-enhancing drugs (PED), also known as “doping,” is a common practice among professional athletes in Iran and this global phenomenon is a serious social problem. The main purpose of this research is to test the efficacy of Gottfredson and Hirschi’s conceptualization of low self-control in conjunction with their ideas of effective parenting and rational choice, in explaining why athletes engage in doping activity. Using self-report data from a random sample of 606 professional athletes from Rasht, Iran, the current study indicates that there are significant associations between ineffective parenting, self-control, perceived costs, and doping activity.     

Impact of Perceived Authentic Leadership and Psychological Capital on Burnout: Mediating Role of Psychological Ownership

The present study is an empirical endeavor of exploring the role of promotive and preventative psychological ownership in the relationship of authentic leadership and psychological capital with burnout. A cross-sectional survey study was conducted among 500 faculty members of various public sector universities of Pakistan (209 male and 291 female teachers). PsyCap Questionnaire, Authentic Leadership Questionnaire, Psychological Ownership Questionnaire, and Maslach Burnout Inventory-Educator Survey were used to measure the focal constructs of the present study. Structured equation modeling reveals that promotive psychological ownership had a negative, whereas preventative psychological ownership had a positive relationship with burnout. Psychological capital and perceived authentic leadership had a negative influence on burnout. Promotive psychological ownership mediated the relationship of psychological capital and authentic leadership with burnout, whereas preventative psychological ownership mediated between perceived authentic leadership and burnout. Implications of the research along with its limitation and suggestions for further research were reflected upon.     

Accidents happen: Psychological empowerment as a moderator of accident involvement and its outcomes

Research in the occupational safety realm has tended to develop and test models aimed at predicting accident involvement in the workplace, with studies treating accident involvement as the starting point and examining its outcomes being more rare. In this study, we examine the relationship between accident involvement and a series of outcomes drawing upon a learned helplessness theory perspective. Specifically, we predicted that psychological empowerment would moderate the relationship between prior accident involvement and outcomes. We tested our hypotheses on a sample of 392 employees and their 66 supervisors working in an iron and steel manufacturing firm in Southern Turkey, using data collected from employees and their supervisors via four separate surveys. Results suggest that accident involvement was positively related to supervisor‐rated employee withdrawal, production deviance, and sabotage only when psychological empowerment was low. The results illustrate that workplace accidents have indirect costs in the form of higher withdrawal and maladaptive behaviors, and organizations may inoculate employees against some of these outcomes via higher psychological empowerment.
