Links between justice sensitivity and moral reasoning,moral emotions,and moral identity in middle childhood

Associations between moral-related traits, such as justice sensitivity (JS), the tendency to negatively respond to injustice, and moral development are largely unknown. From May to December 2018, 1329 5- to 12-year-olds (M = 8.05, SD = 1.02; 51.2% girls, 1.3% transgender and gender-nonconforming) from Germany rated their JS, moral reasoning, emotions, and identity; parents and teachers rated children's theory of mind (ToM) and empathy. Victim JS (caring for own justice) predicted more attributions of positive emotions to norm transgressors in structural equation models (β = .295). Altruistic JS (caring for other's justice) predicted less attributions of positive emotions (β = −.343) and a stronger moral identity (β = .392) unless ToM was considered. Particularly altruistic JS showed associations with advanced moral development. Hence, moral-related traits deserve more attention by moral-development research.     

Influence of recovery intensity on time spent at maximal oxygen uptake during an intermittent session in young,endurance-trained athletes

Abstract

In this study, we examined the effects of three recovery intensities on time spent at a high percentage of maximal oxygen uptake (t90[Vdot]O_2max) during a short intermittent session. Eight endurance-trained male adolescents (16 ± 1 years) performed four field tests until exhaustion: a graded test to determine maximal oxygen uptake ([Vdot]O_2max; 57.4 ± 6.1 ml · min^?1 · kg^?1) and maximal aerobic velocity (17.9 ± 0.4 km · h^?1), and three intermittent exercises consisting of repeat 30-s runs at 105% of maximal aerobic velocity alternating with 30 s active recovery at 50% (IE₅₀), 67% (IE₆₇), and 84% (IE₈₄) of maximal aerobic velocity. In absolute values, mean t90[Vdot]O_2max was not significantly different between IE₅₀ and IE₆₇, but both values were significantly longer compared with IE₈₄. When expressed in relative values (as a percentage of time to exhaustion), mean t90[Vdot]O_2max was significantly higher during IE₆₇ than during IE₅₀. Our results show that both 50% and 67% of maximal aerobic velocity of active recovery induced extensive solicitation of the cardiorespiratory system. Our results suggest that the choice of recovery intensity depends on the exercise objective.     

Influence of free surface,unsteadiness and viscous effects on oar blade hydrodynamic loads

Abstract

Flow around a rowing blade is a very complex phenomenon, involving unsteady three-dimensional flow with violent motion of the free surface. However, in the literature, forces acting on blades are modelled using extreme and dubious simplifications. The aim of the present study was to evaluate the influence of free surface and unsteadiness (two physical characteristics that are commonly neglected when modelling loads on blades) as well as viscous effects. In fact, quasi-static approaches are often used, with no influence of the free surface effects. To conduct this study, computational fluid dynamics is used, supported by experimental results performed with a dedicated device reproducing a simplified rowing stroke in the towing tank. Comparisons show that both free surface flow and unsteadiness must be considered to capture the whole physics of the phenomenon accurately. In contrast, the viscous effects have a very limited influence.     

Trait self-esteem and claimed self-handicapping motives in sports situations

Abstract

We examined the relationship between physical self-esteem and claimed self-handicapping among athletes by taking motives into consideration. In Study 1, 99 athletes were asked to report their tendency to engage in claimed self-handicapping for self-protective and self-enhancement motives (trait measures). Low self-esteem athletes reported a higher tendency to engage in claimed self-handicapping for these two motives compared with high self-esteem athletes. Neither low nor high self-esteem athletes reported a preference for one motive over the other. In Study 2, 107 athletes participated in a test that was ostensibly designed to assess high physical abilities – and thus to encourage self-handicapping for self-enhancement motives (success-meaningful condition) – or to assess low physical abilities, and thus to encourage self-handicapping for self-protective motives (failure-meaningful condition). Before starting the test, athletes were given the opportunity to claim handicaps that could impair their performance. Low self-esteem athletes claimed more handicaps than high self-esteem athletes in both conditions. Findings suggest that low physical self-esteem athletes engage more in claimed handicapping regardless of motives, relative to high physical self-esteem athletes.     

Simulating the Ethical Community: Interactive Game Media and Engaging Human Rights Claims

Abstract

This paper examines the external bystander’s (un)ethical engagement with the suffering of distant others in the brave new world of the 21st century, where, thanks to the growth of information technologies, we are all daily spectators and bystanders of human atrocity. In a recent turn, humanitarian movements have sought to incite their audiences to action through the use of simulation and new game media – the last few years have seen a surge of ‘serious games’ such as Darfur is Dying and Sim Sweatshop, as well as the creation in online community Second Life of simulated refugee camps and political protests. The paper draws on the post‐modern theories of Jean Baudrillard and Slavoj ?i?ek, as well as the ethical philosophies of Michael Ignatieff, Stanley Cohen and Avishai Margalit, to expose the limitations of this move, arguing that interactivity and public remembering via online simulations are more properly aligned, in the real world, to interpassivity and ethical amnesia than to the forging of an effective ethical community of human beings.

Lasting impacts of an Aboriginal youth leadership retreat: a case study of Alberta’s Future Leaders Program

In this paper, we use a postcolonial lens to analyze the impacts of Aboriginal youth’s participation in Alberta’s Future Leaders Program’s youth leadership retreat. While the retreat appeared to have positive lasting impacts on many of the participants, it seemed to have the greatest impact on those who already displayed Eurocentric leadership skills; it had little effect on those who did not display these skills prior to retreat participation and it focused on North American, Eurocentric approaches to leadership. By becoming more culturally relevant, we argue that the retreat could have broader impacts on a greater number of Aboriginal youth.
