Group cohesiveness in children free-play activity: A social network analysis

Despite the ethnic diversity and presence of Amerindian communities in all Brazilian states, the indigenous population suffers from a long process of invisibility and stereotyping. Aiming to increase interethnic associations, together with Mbya-Guarani leaders we promoted interventions in which indigenous and non-indigenous children shared free playtime. We hypothesised that free play activity would stimulate group cohesiveness, mitigating ethnic group avoidance in children's playgroups. Twenty-one Mbya-Guarani and 61 non-indigenous children participated in two “Encounters for Play.” We recorded children's social interactions during the free playtimes. We selected the first and last 10 minutes of each encounter and performed scans every 30s registering spatial proximity (children who were up to 1 m of each other) and play. Then, we applied Social Network Analysis to explore the children's association pattern at the beginning and end of playtime in each encounter. Our results show free play activity was effective in stimulating group cohesiveness. Children' proximity association pattern and playgroup configuration changed between clips, and there was a significant correlation between both categories' associations. We conclude that the encounters have potential applicability as an intervention to mitigate ethnic group avoidance in children.     

A moral vision for the presidential election

The essay celebrates the “Mirror of Princes” writing of political philosophy that appeared in Augustine's City of God, the history of Western political philosophy and in the political thought of ancient China. It upholds the tradition of the good ruler while noting the ambiguities of morality in politics. It notes the political power of the American president in the current global context. While emphasizing the need for the good ruler to love the people he serves it focuses on the need for reform in health care, education, and race relations.     

Language as potential space for relational positioning: Exploring language use as a manifestation of leadership anxiety dynamics

This exploratory study considered language use as a manifestation of anxiety in work and everyday settings. Respondents were seven psychology practitioners from across the discipline (following a psychodynamic approach), who reflected on the dynamics of language use associated with their social and occupational roles. Hermeneutic phenomenological analysis revealed the way in which participants characterised their language use in managing the language of titles and defining potential space for relational, regressive and defensive purposes.     

A novel theory on the predictive value of variation in the β-endorphin system on the risk and severity of PTSD

ABSTRACT

Despite growing interest in genetic and psychosocial indicators of heightened susceptibility to posttraumatic stress disorder (PTSD), a predictive model, which explains why some individuals develop PTSD in response to life-threatening traumatic events, while others, when faced with the same or similar experiences, do not, has thus far remained out of reach. In this paper, we review the literature on gene–environment interactions in β-endorphin system functioning with regard to PTSD and suggest that variation, both genetic and with regard to environmental stimuli, in systems which, like the β-endorphin system, distort human perception of life-threatening traumatic experiences may account for some of the variance in resilience to the disorder. Given the role of β-endorphin in both social connections and physical exercise, this becomes especially relevant with regard to military selection, training, and leadership processes.     

Performance-Enhancing Drug Use in Baseball: The Impact of Culture

Few sports-related events have generated as much controversy as the steroid crisis in baseball. Both ardent fans and casual observers wonder why professional baseball players would choose to use such substances when their use was viewed as outside the bounds of fair play. This article attempts to answer that question by applying concepts from the area of organizational culture. Understanding the culture of baseball and the ways leaders embedded and strengthened that culture adds insight into the decisions by athletes to engage in steroid use. In general, such use was consistent with the already-existing culture. In addition, key decisions and events likely created the conditions in which steroid use was more likely.

Ethical leadership,person-organizational fit,and productive energy: a South African sectoral comparative study

ABSTRACT

Research suggests that ethical leadership (EL) affects employee behavior and organizational functioning. This study aimed to determine the relationship between EL and productive energy (PE), as mediated by person-organizational fit (POF). The study used assumptions of the social learning and social exchange theories that posit that leadership has a direct impact on employee behavior, mainly through role modeling and the reciprocal nature thereof. An empirical paradigm using a cross sectional quantitative design was used. The PE instrument (developed in the USA) was assessed for construct validity within the South African context (exploratory and confirmatory factor analysis). The analysis included a comparison between the private and public sectors, emphasizing the importance of context as differentiator. Relatively high, statistically significant correlations were found between the variables for both sectors and the combined sample. The hierarchical regression analysis indicated that 18% of the variance in PE is explained by EL. This model was improved by the inclusion of POF (total variance of 32% explained). The conceptual model was confirmed with structural equation modeling (SEM). The findings of this study suggest that EL has a significantly positive effect on PE and POF, which mediates the relationship between EL and PE. Sectoral differences were reported.     

Doctors inhibit social threat empathy in the later stage of cognitive processing: Electrophysiological evidence

Previous studies have found that repeatedly exposed to a threatening situation may reduce doctors' level of empathy, reducing psychological stress and avoiding burnout and compassion fatigue. However, many essential studies found that it does not seem universal but rather modulated by group membership. In this study, we recorded event-related potentials (ERP) when doctors and controls watched visual stimuli describing patients attacking doctors (Threat events) or shaking hands with doctors (Neutral events). The present study showed an early N190 and a later centro-parietal P3 differential amplitude between threat stimuli and neutral stimuli were observed in the controls. For the doctors, there was such ERP differentiation in early N190. However, later stage P3 differential amplitude was not observed. The current research suggests that doctors could regulate empathy and avoid allocating more attention resources when processing social threats to ensure treatment efficiency and avoid burnout.
