Kant wants to show that freedom is possible in the face of natural necessity. Transcendental idealism is his solution, which locates freedom outside of nature. I accept that this makes freedom possible, but object that it precludes the recognition of other rational agents. In making this case, I trace some of the history of Kant’s thoughts on freedom. In several of his earlier works, he argues that we are aware of our own activity. He later abandons this approach, as he worries that any awareness of our activity involves access to the noumenal, and thereby conflicts with the epistemic limits of transcendental idealism. In its place, from the second Critique onwards, Kant argues that we are conscious of the moral law, which tells me that I ought to do something, thus revealing that I can. This is the only proof of freedom consistent with transcendental idealism, but I argue that such an exclusively first-personal approach precludes the (third-personal) recognition of other rational agents. I conclude that transcendental idealism thus fails to provide an adequate account of freedom. In its place, I sketch an alternative picture of how freedom is possible, one that locates freedom within, rather than outside of nature.  相似文献

The platinum mining sector in South Africa presents a significant context for the study of work engagement, given the major changes and turmoil experienced by employees in this sector. The aim of this study was to investigate the effects of task and relational factors on work engagement in the platinum mining industry in South Africa. A stratified random sample (N = 564) comprising employees in a platinum mining organisation in South Africa was surveyed (females = 35.1%, blacks = 51.6%, middle managers = 40.8%). The employees completed a biographical questionnaire and several other measures: the Engagement Scale, Supervisory Support Scale, Social Support Scale and Job Diagnostic Survey. The results supported a reliable three-factor structure (consisting of autonomy support, competence support, and relatedness support) for the Supervisory Support Scale. The structural model confirmed that task characteristics (comprising task significance and task identity) were strongly related to work engagement. Supervisor support and co-worker support showed a positive relationship with work engagement, albeit to a lesser extent.  相似文献

This study explores men’s experiences in compensated dating (CD), particularly their process of becoming a client of CD in Hong Kong. By drawing on 30 individual interviews with male clients, cyber-ethnography of a major CD on-line forum, informal conversations with CD participants, off-line participant observations, and the sparse literature available on this under-examined social phenomenon, we also analyze men’s subjective understandings of being a client, of CD providers, and of CD itself, which influence men’s CD experiences and condom use behavior. Finally, this study sheds light on the contemporary issues of masculinity and sexuality in Hong Kong.  相似文献

Our findings draw attention to the interpersonal communication function of a relatively unexplored dimension of emotions—the level of social engagement versus disengagement. In four experiments, regardless of valence and target group gender, observers infer greater relational well-being (more cohesiveness and less conflict) between group members from socially engaging (sadness and appreciation) versus disengaging (anger and pride) emotion expressions. Supporting our argument that social (dis)engagement is a critical dimension communicated by these emotions, we demonstrate (1) that inferences about group members' self-interest mediate the effect of socially engaging emotions on cohesiveness and (2) that the influence of socially disengaging emotion expressions on inferences of conflict is attenuated when groups have collectivistic norms (i.e., members value a high level of social engagement). Furthermore, we show an important downstream consequence of these inferences of relational well-being: Groups that seem less cohesive because of their members' proud (versus appreciative) expressions are also expected to have worse task performance.  相似文献

This study proposes a model based on transactive memory theory to analyze team performance. In the proposed model, team performance is influenced by hypercompetition and emotional regulation directly and indirectly via the mediation of transactive memory and knowledge sharing. According to the model, the direct effect of knowledge sharing on team performance is moderated by both hypercompetition and emotional regulation. Empirical testing of this model, using team personnel in banking, insurance, and financing firms, confirmed the applicability of the transactive memory theory among these service firms’ work teams. Managerial implications and research limitations are discussed.  相似文献

Both psychological theory and empirical research have consistently indicated that human beings use media images to form cognitive schemas, and that these schemas can then have an effect on perceptions of ability and performance. Gender and ethnic biases are well documented in common media, such as television and picture books. This study examined images of human beings in two popular computer clipart packages, Microsoft Office 97 and Print Shop Ensemble III, to investigate whether this new medium would embody modern, egalitarian goals for gender and racial equality or would depict more traditional and differentiated views. As hypothesized, computer clipart was similar to other media, depicting Caucasian males more frequently and in more active/nonnurturant and desirable roles than any other group. Findings suggest that individuals using these programs to make business and educational materials more interesting and engaging may inadvertently activate maladaptive cognitive schemas.  相似文献

The association between adolescents' and young adults' attitudes toward suicide and their own suicidality across five racial-ethnic classifications was studied in a nationally representative sample of 3,301 youth ages 14 to 22 years from the National Annenberg Risk Survey of Youth. Results indicate that adolescents and young adults who most strongly believe that it is acceptable to end one's life are more than fourteen times more likely to make a plan to kill themselves as those who do not have such beliefs (p < .001). Future behavioral prevention and intervention research should take into consideration adolescents' and young adults' approval of suicide as a risk factor for taking their own lives.  相似文献

D-cycloserine (DCS), a partial NMDA receptor agonist, facilitates extinction of learned fear in rats and has been used to treat anxiety disorders in clinical populations. However, research into the effects of DCS on extinction is still in its infancy, with visual cues being the primary fear-eliciting stimuli under investigation. In both human and animal subjects odors have been found to associate strongly with aversive events. Therefore, this study examined the generality of the effects of DCS on extinction by testing odor cues. Sprague-Dawley rats were conditioned and extinguished to an odor using varying parameters, injected with either saline or DCS (15 mg/kg) following extinction, and then tested for a freezing response 24 h later. Experiment 1 demonstrated that after 3 odor-shock pairings, rats did not display short-term extinction and DCS had no effect on long-term extinction. Experiment 2 demonstrated that after 3 odor-noise pairings, rats displayed significant short-term extinction and DCS significantly facilitated long-term extinction. Following 2 odor-shock pairings in Experiment 3, half the rats displayed short-term extinction ("extinguishers") and half did not ("non-extinguishers"). DCS facilitated long-term extinction in the "extinguishers" condition but not in the "non-extinguishers" condition. In Experiment 4, following 2 odor-shock pairings and an extra extinction session, DCS had a significant facilitatory effect on long-term extinction. Thus, extinction of freezing to an odor cue was facilitated by systemic injections of DCS, but only when some amount of within-session extinction occurred prior to injection.  相似文献

The ways in which visual categories are learned, and in which well-established categories are represented and retrieved, are fundamental issues of cognitive neuroscience. Researchers have typically studied these issues separately, and the transition from the initial phase of category learning to expertise is poorly characterized. The acquisition of novel categories has been shown to depend on the striatum, hippocampus, and prefrontal cortex, whereas visual category expertise has been shown to involve changes in inferior temporal cortex. The goal of the present experiment is to understand the respective roles of these brain regions in the transition from initial learning to expertise when category judgments are being made. Subjects were explicitly trained, over 2 days, to classify realistic faces. Subjects then performed the categorization task during fMRI scanning, as well as a perceptual matching task, in order to characterize how brain regions respond to these faces when not explicitly categorizing them. We found that, during face categorization, face-selective inferotemporal cortex, lateral prefrontal cortex, and dorsal striatum are more responsive to faces near the category boundary, which are most difficult to categorize. In contrast, the hippocampus and left superior frontal sulcus responded most to faces farthest from the category boundary. These dissociable effects suggest that there are several distinct neural mechanisms involved in categorization, and provide a framework for understanding the contribution of each of these brain regions in categorization.  相似文献

Although Bangladesh is known as one of the poorest and most densely populated countries in the world, qualitative research and anecdotal evidence suggests its people report levels of happiness that are higher than those found in many other countries. This includes ‘developed’ countries where people have larger per capita incomes and can access a wider range of public services and goods. The paper explores this apparent paradox by analysing primary quantitative and qualitative data, and engaging with existing literature on happiness and objective wellbeing in Bangladesh. The data and analysis presented makes an original and timely contribution to the limited knowledge we have of the construction and experience of happiness and life satisfaction in contexts of extreme and persistent economic poverty. It identifies and offers insights into the ‘personal’ as well as social or ‘relational’ values and goals that people in Bangladesh consider important to achieve happiness in life. It also reflects on how different people experience these values and goals in very different ways. This, we argue, leads to a better understanding of the influence of the social and cultural context in the construction of people’s happiness. In the conclusion, we reflect on the policy implications of our findings.
