This study examined the use of punitive coaching strategies in youth sport and the nature of these experiences for youth athletes. Semistructured interviews and concept maps were conducted with 12 competitive male and female hockey athletes 11–13 years of age. Data were analyzed using inductive thematic analysis. Results revealed that punishments occurred in competitive youth hockey, in the forms of benching, yelling, exercises, cleaning up equipment, and alternating positions. Findings are interpreted to suggest that punishments hindered developmental needs of youth athletes, including a positive sense of self and positive relationships with others. Implications for healthy youth development are discussed. 相似文献

Users and potential users of the sharing economy need to place a considerable amount of trust in both the person and the platform with which they are dealing. The consequences of transaction partners’ opportunism may be severe, for example damage to goods or endangered personal safety. Trust is, therefore, a key factor in overcoming uncertainty and mitigating risk. However, there is no thorough overview of how trust is developed in this context. To understand how the trust of users in the sharing economy is influenced, we performed a systematic literature review. After screening, 45 articles were included in a qualitative synthesis in which the results were grouped according to a well‐established trust typology. The results show various antecedents of trust in the sharing economy (e.g. reputation, trust in the platform, and interaction experience) related to multiple entities (i.e. seller, buyer, platform, interpersonal, and transaction). Trust in this economy is often reduced to the use of reputation systems alone. However, our study suggests that trust is much more complex than that and extends beyond reputation. Furthermore, our review clearly shows that research on trust in the sharing economy is still scarce and thus more research is needed to understand how trust is established in this context. Our review is the first that brings together antecedents of trust in online peer‐to‐peer transactions and integrates these findings within an existing framework. Additionally, the study suggests directions for future research in order to advance the understanding of trust in the sharing economy. 相似文献

This paper centres on the question as to whether human rights can be reconciled with patriotism. It lays out the more conventional
arguments which perceive them as incommensurable concepts. A central aspect of this incommensurability relates to the close
historical tie between patriotism and the state. One further dimension of this argument is then articulated, namely, the contention
that patriotism is an explicitly political concept. The implicit antagonism between, on the one hand, the state, politics
and patriotism, and, on the other hand, human rights, is illustrated via the work of Carl Schmitt. However, in the last few
decades there has been a resurgence of interest in patriotism and an attempt to formulate a more moderate form, which tries
to reconcile itself with universal ethical themes. Some of these arguments are briefly summarised; the discussion then focuses
on Jürgen Habermas’s understanding of constitutional patriotism. This is seen to provide an effective response to Schmitt’s
arguments. There are weaknesses in the constitutional patriotic argument which relate to its limited understanding of both
the state and politics. This leads me to formulate my own argument for “unpatriotic patriotism.” The discussion then examines
and responds to certain potential criticisms of this argument. 相似文献

The authors have argued elsewhere that the attentional blink (AB; i.e., reduced target detection shortly after presentation
of an earlier target) arises from blocked or disrupted perceptual input in response to distractors presented between the targets.
When targets replace the intervening distractors, so that three targets (T1, T2, and T3) are presented sequentially, performance
on T2 and T3 improves. Dux, Asplund, and Marois (2008) argued that T3 performance improves at the expense of T1, and thus
provides evidence for resource depletion. They showed that when T1 is made more salient (and presumably draws more resources),
an AB for T3 appears to reemerge. These findings can be better explained, however, by (1) the relationship between T1 and
T2 (not T1 and T3) and (2) differential salience for T3 in the long-lag condition of Dux et al.’s study. In conclusion, the
Dux et al. study does not present a severe challenge to input control theories of the AB. 相似文献

Functional magnetic resonance imaging was used to investigate the neural correlates of passive listening, habitual speech and two modified speech patterns (simulated stuttering and prolonged speech) in stuttering and nonstuttering adults. Within-group comparisons revealed increased right hemisphere biased activation of speech-related regions during the simulated stuttered and prolonged speech tasks, relative to the habitual speech task, in the stuttering group. No significant activation differences were observed within the nonstuttering participants during these speech conditions. Between-group comparisons revealed less left superior temporal gyrus activation in stutterers during habitual speech and increased right inferior frontal gyrus activation during simulated stuttering relative to nonstutterers. Stutterers were also found to have increased activation in the left middle and superior temporal gyri and right insula, primary motor cortex and supplementary motor cortex during the passive listening condition relative to nonstutterers. The results provide further evidence for the presence of functional deficiencies underlying auditory processing, motor planning and execution in people who stutter, with these differences being affected by speech manner. 相似文献

In large social groups acoustic communication signals are prone to signal masking by conspecific sounds. Bottlenose dolphins (Tursiops truncatus) use highly distinctive signature whistles that counter masking effects. However, they can be found in very large groups where masking by conspecific sounds may become unavoidable. In this study we used passive acoustic localization to investigate how whistle rates of wild bottlenose dolphins change in relation to group size and behavioral context. We found that individual whistle rates decreased when group sizes got larger. Dolphins displayed higher whistle rates in contexts when group members were more dispersed as in socializing and in nonpolarized movement than during coordinated surface travel. Using acoustic localization showed that many whistles were produced by groups nearby and not by our focal group. Thus, previous studies based on single hydrophone recordings may have been overestimating whistle rates. Our results show that although bottlenose dolphins whistle more in social situations they also decrease vocal output in large groups where the potential for signal masking by other dolphin whistles increases. 相似文献

We studied the roles of the basolateral amygdala (BLA) and the medial prefrontal cortex (mPFC) in learning and relearning to inhibit context conditioned fear (freezing) in extinction. In Experiment 1, pre-extinction BLA infusion of the NMDA receptor (NMDAr) antagonist, ifenprodil, impaired the development and retention of inhibition but post-extinction infusion spared retention. Pre-extinction infusion of the GABA(A) agonist, muscimol, depressed freezing and impaired retention as did post-extinction infusion. In Experiment 2, pre-extinction mPFC infusion of ifenprodil spared the development of inhibition whereas muscimol depressed freezing. Both impaired retention when infused pre- or post-extinction. Thus, the development of inhibition involves NMDAr activation in the BLA, whereas its consolidation involves both NMDAr activation in the mPFC and NMDAr-independent mechanisms in the BLA. In Experiment 3, BLA infusion of ifenprodil impaired relearning and retention of inhibition when infused before but did not impair retention when infused after re-extinction. BLA infusion of muscimol depressed freezing but did not impair retention when infused before or after re-extinction. In Experiment 4, mPFC infusion of ifenprodil impaired relearning when infused before re-extinction, whereas muscimol depressed responses. Both drugs impaired retention when infused into the mPFC before or after re-extinction. Thus, relearning to inhibit fear responses involves NMDAr activation in both the BLA and mPFC and consolidation of the inhibitory memory involves NMDAr activation in the mPFC. However, relearning and consolidation occur in the absence of neuronal activity within the BLA. We propose that NMDAr in the mPFC supports relearning inhibition when the BLA is inactivated. 相似文献

The new European regulation of medical devices presents today a considerable stake for the economic operators. In addition to strengthening their requirements, the 2017/745 and 2017/746 regulations describe with greater precision their respective roles. Compensation for damage caused by medical devices is also a major challenge for the European legislator. In addition to an obligation of insurance towards the manufacturer, he has defined a regime of strict responsibility of the agent, modeled on the directive 85/374/EEC on responsibility for defective products. 相似文献

This article describes the working method of our study group comprised of former Chestnut Lodge Hospital therapists and focusing on understanding therapeutic work with severely disturbed adolescents. Using process material from one therapy session, the therapist’s commentary on her feelings and reactions in the session, and the group’s discussion of the work, we explore factors disrupting the therapist’s moment-to-moment capacity to maintain a theory of her own and the patient’s minds. We then discuss what allows her to refind her theory of mind in the face of the patient’s aggressive nihilism and her own sense of loss. Salutary factors included the therapist’s empathy for the patient’s shared sense of grief, the patient’s offering the therapist cues to his inner state, and the dyad’s capacity to tolerate the therapist’s vulnerability in the patient’s presence. 相似文献

The activation-selection model (ASM) of determining the meaning of an ambiguous word is unique in that it is able to account for the long-term effects of meaning selection without an explicit mechanism for suppressing the representation of the nonselected meaning. The model assumes that a meaning is selected when a threshold number of attributes associated with that particular meaning are activated. When a meaning is selected, the ASM assumes that the weights of the attributes that are associated with the chosen meaning are increased. This two-phase process (transient activation followed by long-term weight changes) provides a mechanism by which meaning selection at one time can affect meaning selection at a much later time. The ASM can explain the results of the presently reported experiments, in which the meaning selected for a homophone presented in an unbiased context is affected by multiple previous presentations of the homophone in different contexts. In particular, although participants who are initially oriented toward the secondary meaning of a homophone show an increased proportion of dominant responses when next primed by the dominant meaning of the homophone, the proportion of dominant responses decreases to below baseline levels when the homophone is later presented in a neutral context, indicating the lasting influence of the initial secondary meaning context. 相似文献
