Abstract

Purpose

Research reports a positive relationship between parental rejection and antisocial behavior in adolescents and young adults. Studies also report a positive association between testosterone and antisocial behavior. The purpose of this paper is to examine whether testosterone moderates the influence of parental rejection on antisocial behavior in a sample of young adults.

Design/methodology/approach

The current study analyzed a sample of undergraduate students (N=322) to examine the interaction between testosterone and parental rejection in the prediction of antisocial behavior. Multivariate ordinary least squares (OLS) regression was used to explore this association.

Findings

Results from OLS regression models revealed that parental rejection and testosterone were independently associated with antisocial behavior and that the effect of parental rejection on antisocial behavior was stronger at higher levels of testosterone.

Originality/value

This current study is the first to examine how testosterone conditions the influence of parental rejection on antisocial behavior in young adults. Findings from the study add to the growing body of literature examining the interplay between biological and environmental factors.

Abstract

Teenagers are typically described as impulsive and risk taking. Yet recent research shows that this observation does not hold in all contexts. Rather, adolescents show higher impulsivity and risk taking than children or adults in affective contexts. Motivational and affective processes are therefore of particular interest when trying to understand typical adolescent behavior. Additionally, pubertal hormones are hypothesized to play a special role in adolescents’ motivated decision making. However, evidence for the mechanisms underlying this relationship is sparse. In this chapter, we aim to integrate findings from human and animal studies in order to elucidate the specific impact of pubertal hormones on motivational processes in adolescence. Against this background, we critically discuss and reinterpret recent findings in psychology and neuroscience, speculate about underlying mechanisms, and suggest new approaches for future studies of adolescent behavior.

Abstract

Purpose

Team effectiveness is often predicated by a group’s ability to communicate. However, the effect of stress response on communication success, particularly nonverbal engagement, and how this might affect team performance, is not clear; a “phenomenon” this study sought to explore.

Design/methodology/approach

This was an observational study in a cohort of professional rugby players. Participants gave presentations to their peers on two separate occasions during a “live-in” camp designed to have psychologically stressful elements. Presentations were video recorded and audience engagement was measured. Testosterone and cortisol were used as biomarkers of stress response, with a high testosterone–cortisol ratio considered positive. A team training session followed the presentations and participants were rated for training quality.

Findings

A small decline in testosterone was observed each day after waking. Conversely, cortisol rose after waking, with the rise being the highest on the first day. A decline in testosterone–cortisol ratio was also seen each day after waking; the decline was greatest on the first day. Presentation duration and audience engagement was greatest for the second presentation; when the testosterone-cortisol ratio decline and the cortisol increase after waking was smaller. Training quality was also better that day. Pooled data revealed a moderate inverse relationship and weak positive relationships for audience engagement with post-meeting cortisol and post-meeting testosterone–cortisol ratio, respectively. Training quality was related to testosterone and testosterone–cortisol ratio, but inversely related to cortisol.

Originality/value

This study suggests that in stressful conditions, as suggested by an awakening hormone response, communication and team performance could become compromised with reduced ability to engage with others.

Abstract

The importance of anabolism and regeneration is related to lack or loss of control. This chapter discusses the psychophysiological basis for such relationships. In the threat of lost control, energy mobilisation is activated and regeneration is inhibited – since regeneration (repairing) has low priority in emergency situations. This pattern can be traced on several psychophysiological levels, from the brain to most of the cells in the body. Such a mechanism explains why the body becomes vulnerable and increasingly sensitive to load when threat of lost control is excessive and long lasting. In several empirical examples, various indicators of anabolism and regeneration have paralleled improvement versus deterioration in psychosocial conditions, in particular lack or loss of control. In these studies, indicators of anabolism and regeneration (such as concentration of sex hormones with anabolic and regenerative functions in blood and saliva) have been followed in subjects going through deteriorating versus improving life conditions. The demand-support model is used as a theoretical basis for the discussion.

Abstract

Purpose: In this chapter, I analyze proceedings from 2015 when the Court of Arbitration for Sport (CAS) was asked to determine whether Dutee Chand, an Indian sprinter, could compete as a female athlete. Excluded on the basis that her naturally high testosterone levels conferred an unfair athletic advantage, Chand argued that existing policies in international sport were scientifically flawed. The purpose of the analysis is to examine whether the case led to a shift in the gender politics of sport, law, and science.

Methodology/Approach: I present a textual analysis of the arbitral award document, drawing on feminist methodology to identify where and how the adjudicating panel’s assessment of the case was gendered.

Findings: The CAS decision defined the right to compete as primarily a matter for science to decide, in the process obscuring the gendered and tilted playing field upon which scientific knowledge production takes place. Furthermore, the right to unconditional recognition as a woman was reduced to science alone.

Social Implications: My analysis reveals that Chand’s victory is a precarious one, with binary and biologized models of sex and gender prevailing when the institutions of sport, law, and science determine the policy boundaries of “fair play” for female athletes.

Originality/Value of Study: This chapter shows how the institutions of sport, law, and science work together to determine gender. As a consequence, even feminist versions of the biology of sex difference risk reifying the authority of science as the dominant knowledge form within the institutional spaces of sport and law.

Abstract

We are in the midst of a broad societal change in which women’s sexual problems are becoming increasingly medicalized, characterized as treatable medical conditions and defined and understood as a largely physiologically based disease, called “female sexual dysfunction” (FSD). When a condition is medicalized, a medical framework is used to understand it, and medical interventions are used to treat it. As part of this process, then, over the last several years, researchers and pharmaceutical companies have turned attention to developing medical treatments for FSD. As this medicalization continues to unfold with potentially important impacts, it is crucial that we understand the forces working to shape it.

Abstract

Purpose

This paper aims to investigate the role of nature and nurture in students’ entrepreneurial intention (EIs). In doing so, the study examines the relationship between prenatal testosterone exposure (2D:4D), risk-taking propensity, entrepreneurial self-efficacy and EIs. Moreover, the moderating role of entrepreneurial education between entrepreneurial self-efficacy and EI is also investigated.

Design/methodology/approach

In line with previous studies on EI, the authors tested hypotheses based on quantitative data obtained from university students.

Findings

Data were analyzed with the help of the structural equation modeling technique, and the results revealed that all the hypothesized relationships were supported.

Originality/value

The field of entrepreneurship has become an attractive area of research for practitioners and academics. One tinted area of research in entrepreneurship is the investigation of EI because it is a good predictor of entrepreneurial behavior. Several antecedents of EIs have been recognized in the literature ranging from personality traits to environmental factors. However, less is known about the role of biology in entrepreneurship. Incorporating biological factors in the field of entrepreneurship appears to be theoretically viable and sound. Thus, this study investigates the effect of biological factors in the presence of psychological factors on EIs, which is a unique contribution to the literature on entrepreneurship.

Abstract

Purpose

This paper aims to design to evaluate the protective effect of vitamin E to ameliorate the disturbances in testosterone pathway and sperm quality of male rats induced by the glycosides vicine (V) and convicine (C) of Vicia faba.

Design/methodology/approach

Forty male albino rats were divided into five equal groups; control, paraffin oil, V (400 mg/kg) C (150 mg/kg)-treated group, vitamin E (100 mg/kg) + VC-treated group, and vitamin E (200 mg/kg) + VC-treated groups which injected intraperioneally (IP) with 0.5-ml saline, 0.5-ml paraffin oil,V (400 mg/kg) and C (150 mg/kg) of Vicia faba, vitamin E (100 mg/kg) + VC-treated groups, and Vitamin E(200 mg/kg) + VC-treated groups, respectively. Blood and testicular tissue were obtained after one month of the study. The male genital organs were calculated. Testosterone (Ts), luteinizing hormone (LH), follicle stimulating hormone (FSH), dehydroepiandrosterone sulfate (DHEA-SO4), sex hormone binding globulin (SHBG),?-glutamyl transpeptidase (?-GT), glucose-6-phosphate dehydrogenase (G6PD), 3ß-hydroxysteroid dehydrogenase (3ßHSD), lactate dehydrogenase (LDH), spermatozoa concentration, percent of mortality and abnormal sperms were evaluated.

Findings

The VC-treated group showed significant decrease (p < 0.01) in Ts, DHEA-SO4, G6PD, spermatozoa number and mortality percent, as well as, the male genital organs (testes, epidydemis, seminal vesicle, prostate and vasa deferentia) while significant increase (p < 0.01) was found in LH, FSH, SHBG, LDH, ?-GT, sperms monoclonal Ki-67, and abnormal spermatocytes levels compared with control group. Vitamin E co-injection with VC-treated group returned all these parameters to the normal values. The higher dose of vitamin E (200 mg/kg) was more effect than the lower dose (100 mg/kg).

Originality/value

Vicia faba contains V and C glycosides. The V and C glycosides in Vicia faba are hydrolyzed by intestinal microflora to aglycones divicine and isouramil, respectively. Divicine and isouramil are highly reactive compounds generating free radicals where divicine and isouramil are the main factors of favism. The V and C glycosides induced disturbances in testosterone pathway and sperm quality of male rats and vitamin E ameliorates these disturbances.

Abstract

Purpose

The management of sexual offending is a major challenge, particularly in men who have an intellectual disability. Psychological therapies have been shown beneficial, and programmes designed for use in the general population have been adapted for use in offenders who have an intellectual disability. There is also a role for pharmacological management, although the quality of evidence for this is noticeably lacking, most likely associated with the ethical and legal issues encountered in conducting well designed and controlled trials in this area. The purpose of this paper is to look at the pharmacological management options available.

Design/methodology/approach

A literature search of electronic databases was undertaken. Additionally, the references lists for identified papers were examined for any further relevant publications.

Findings

The two main categories of drugs used in the management of inappropriate sexual behaviour are the testosterone-lowering drugs and the psychotropic drugs. Most trials were open and utilised self-report measures of drug effectiveness, limiting their usefulness. Most trials noted beneficial effect. Side effect profiles and patient adherence can limit the effectiveness of anti-libidinal medication in practice.

Originality/value

There is very limited evidence available for the use of pharmacological agents in the management of inappropriate sexual behaviour, owing to the lack of adequately controlled clinical trials. New studies are therefore required, particularly of larger sample sizes, longer durations, and examining characteristics of those who benefit from pharmacological treatment, although the ethical issues of conducting such studies is duly acknowledged.
