Background and objective
Field invasion games, such as rugby union, can be conceptualised as dynamic social systems in which the agents continuously interact to contest ball possession and territorial gain. Accordingly, this study aimed to identify the collective system dynamics of rugby union phases-of-play near the try line by investigating whether ball displacement trajectory on the playing field provides insights on successful team performance.Methods
Five rugby union matches were videotaped involving teams at a national league performance level. From these matches, 22 second phases-of-play were selected and digitized for analysis. The variable “distance gained” was investigated as a potential coordination variable describing functional coordination between players and teams. This variable concerned the distance between ball initial position and ball current position over time and was used to define the degree of territory gained by an attacking team.Results
Analysis of distance gained dynamics in attacking sub-phases demonstrated the intermittent character of rugby union performers displacement trajectories on the playing field. Amplitude of ball movements was revealed as a distinguishing feature related to attacking effectiveness. Successful attacking phases displayed lower distances of positional retreat, with the maximum retreat distance achieved sooner in successful compared to unsuccessful phases-of-play. Autocorrelation and ApEn analyses suggested low system variability within time series data concerning both performance outcomes. However, evidence of less regularity and more complexity was found in unsuccessful phases-of-play.Conclusion
Results suggested that distance gained dynamics manifests a characteristic collective behaviour pattern that captures the macroscopic functional order of multi-player attack–defence systems in team sports like rugby union. 相似文献32.
In this article, we take the case of racism in contemporary Italy as a starting point for a discussion about moral responsibility for racism in cases where ignorance is involved. We focus on the issue of the normalization of racism and its contribution to different forms of ignorance to assess the extent to which these might potentially mitigate judgments of responsibility for racism, thereby grounding an Exculpatory Stance. After illustrating the phenomenon of the normalization of racism and offering an outline of how the normalization of racism contributes to ignorance, we argue against the Exculpatory Stance by appealing to a socially situated variety of capacitarian approach to the epistemic condition of moral responsibility. This approach provides us with the tools to claim that the moral ignorance favored by the normalization of racism does not mitigate judgments of individual responsibility. Finally, we point out that the interdependence of individual responsibility and the social environment is such that, in addition to backward-looking individual responsibilities for racism, there are also forward-looking, both individual and shared, responsibilities to counter racism in its various manifestations and the increased risk of moral ignorance connected to its normalization. 相似文献

Play provides children learning opportunities in the natural environment to acquire communication skills. While working to establish skills that may lead to additional leisure and social opportunities of children with autism spectrum disorder (ASD), procedures need to be both effective and efficient. One way to increase efficiency of teaching is through the use of instructive feedback (IF). Therefore, the purpose of the current study is to systematically replicate and extend previous research by examining if play behaviors emerge when using IF to teach conceptually related primary (i.e., tacts) and secondary targets (i.e., play skills). The results of the present study extend previous research by demonstrating the effectiveness of teaching tacts to individuals with ASD, and that using IF during tact training can help promote the acquisition of play skills. 相似文献

In this paper, I review arguments according to which harsh criminal punishments and poverty are undeserved and therefore unjust. Such arguments come in different forms. First, one may argue that no one deserves to be poor or be punished, because there is no such thing as desert-entailing moral responsibility. Second, one may argue that poor people in particular do not deserve to remain in poverty or to be punished if they commit crimes, because poor people suffer from psychological problems that undermine their agency and moral responsibility. Third, one may argue that poor and otherwise marginalized people frequently face external obstacles that prevent them from taking alternative courses of action. The first kind of argument has its place in the philosophy seminar. Psychological difficulties may be important to attend to both in personal relationships and when holding ourselves responsible. Nevertheless, I argue that neither type of argument belongs in political contexts. Moral responsibility scepticism ultimately rests on contested intuitions. Labelling certain groups of people particularly irrational, weak-willed, or similar is belittling and disrespectful; such claims are also hard to prove, and may have the opposite effect to the intended one on people's attitudes. Arguments from external obstacles have none of these problems. Such arguments may not take us all the way to criminal justice reform, but in this context, we can supplement them with epistemic arguments and crime prevention arguments. 相似文献

Apathy is a common, disabling neuropsychiatric syndrome that occurs across many brain disorders and may be associated with diminished motivation in behavioural, cognitive, emotional and social domains. Assessment is complicated by the variability of symptoms across apathy domains and self-report from patients, which can be misleading due to their lack of insight. Independent evaluation by clinicians also has limitations though if it has to be performed with limited time. Caregiver reports are a viable alternative, but current assessments for them either do not distinguish between different apathy domains or are interview-based and take long to administer. In this study, we developed a brief caregiver questionnaire version of the recently developed Apathy Motivation Index (AMI), which is a self-report tool. We confirmed three apathy factors in this new caregiver measure (AMI-CG) that were also present in the AMI: Behavioural Activation, Emotional Sensitivity and Social Motivation. Furthermore, we validated the scores against more extensive caregiver interviews using the established Lillle apathy rating scale as well as patient self-reports of apathy, measures of depression, anhedonia, cognition, activities of daily living and caregiver burden across four different neurological conditions: Parkinson's disease, Alzheimer's disease, subjective cognitive impairment and limbic encephalitis. The AMI-CG showed good internal reliability, external validity and diagnostic accuracy. It also uncovered cases of social apathy overlooked by traditional instruments. Crucially, patients who under-rated their apathy compared to informants were more likely to have difficulties performing everyday activities and to be a greater burden to caregivers. The findings provide evidence for a multidimensional conceptualization of apathy and an instrument for efficient detection of apathy based on caregiver reports for use in clinical practice. 相似文献

We conducted a cross-sectional study investigating whether sport identification predicts different forms of collective action intentions aimed to redress the unfavourable condition faced by disadvantaged individuals. In doing so, moral perceptions (moral convictions, moral violation and moral obligation) were tested as mediators. Participants were young football players from the grassroots of a professional Italian club (N = 111). Results revealed that sport identification was indirectly associated with greater willingness to engage in both normative and non-normative solidarity-based collective action via stronger moral obligation perceptions; moral convictions mediated the relationship between sport identification and normative collective action, while no mediation effects emerged for moral violation. We discuss findings in relation to collective action and sport research. 相似文献

The present research tested a prejudice‐reduction intervention based on imagined contact. White children imagined interacting with a child from an ethnic out‐group (Asian) once a week for 3 weeks, or did not take part in this activity (control group). Compared with the control group, children who engaged in imagined contact subsequently showed more positive attitudes, greater perceived similarity, and willingness for intergroup contact. The effect of the intervention on willingness for contact was mediated by positive attitude change. Implications for imagined‐contact theory and the development of prejudice‐reduction techniques for schools are discussed. 相似文献

It is well established that the importance assigned to a trauma can affect one's recovery and psychological health in numerous ways. Event centrality is an increasingly popular construct that captures the tendency among survivors to reevaluate and possibly accommodate their worldviews posttrauma. The centrality given to trauma appears to serve as a “double-edged sword” in that this construct might factor prominently in both posttraumatic stress disorder (PTSD) and posttraumatic growth (PTG). Focusing on 257 violence-exposed teachers from educational departments throughout El Salvador, we examined whether the centrality assigned by the teachers to stressful life events uniquely predicted both PTSD symptomatology and PTG. Results revealed that event centrality was positively related to both PTSD and PTG, even when controlling for demographic factors, violence exposure, and depression. In addition, PTSD symptomatology and PTG were not associated with one another in this sample. In summary, these findings support the role of event centrality as a contributing factor for PTSD and PTG among persons exposed to pervasive trauma. 相似文献

Humanitarian aid professionals frequently encounter situations in which one is conscious of the morally appropriate action but cannot take it because of institutional obstacles. Dilemmas like this are likely to result in a specific kind of stress reaction at the individual level, labeled as moral stress. In our study, 16 individuals working with international humanitarian aid and rescue operations participated in semistructured interviews, analyzed in accordance with a grounded theory approach. A theoretical model of ethical decision making from a moral stress perspective was developed. The practical implications of the study are discussed. 相似文献
