There is growing concern about the polarizing impact of citizens primarily choosing sources of political information consistent with their existing partisan perspective. Although research has begun providing answers about the consequences, questions remain about what factors drive such selective use of political media. This study conceptualizes partisanship as a social identity and the decision to selectively use like-minded political media as a method for maintenance of that identity. Using the logic of the reinforcing spirals model (Slater, 2007, 2015), we investigated partisan media selectivity as a response to identity threat. We argue the partisan composition of one’s geographic locale and the presence of partisan difference in one’s interpersonal network are common causes of identity threat, which we predict will be associated with compensatory use of partisan media. Results from national survey data generally provide support for the assertion that greater partisan media selectivity is associated with the presence of various forms of identity threat, especially for strong partisans.  相似文献

In this article we highlight temporal effects in information and communication technology-enabled organizational change. Examples of temporal effects are explored in the context of one organization's efforts to implement an enterprise-wide information system. Temporality is presented as having two aspects, with the first being the well-recognized, linear and measured clock time. The second aspect of time is that which is perceived--often as nonlinear--and socially defined. We find that temporal effects arise both in changes to the structure of work and in differences among groups in how time is perceived. Evidence suggests that both specific characteristics of the implementation and of the enterprise systems' technologies further exacerbate these temporal effects. We conclude with suggestions for how to incorporate a temporally reflective perspective into analysis of technology-enabled organizational change and how a temporal perspective provides insight into both the social and technical aspects of the sociotechnical nature of enterprise systems.  相似文献

OBJECTIVE: The purpose of the present study was to provide preliminary data extending earlier research on shame and guilt, examining their relationships both to symptoms of depression and to psychological maltreatment. Symptoms of depression were expected to correlate positively with shame, but not with guilt. Psychological maltreatment was also expected to correlate positively with shame. The relationship between psychological maltreatment and guilt was examined on an exploratory basis. METHOD: Two hundred and eighty participants from a public community college and a private university completed scales assessing shame, guilt, depression, and history of childhood psychological maltreatment. Pearson correlations were conducted with all data. RESULTS: Results indicated that symptoms of depression were positively correlated with both shame and guilt. Partial correlations were then conducted in which the linear effects of shame were removed from guilt. In this latter analysis, guilt was no longer positively correlated with symptoms of depression. Psychological maltreatment was also positively correlated with depression and with shame, but not with guilt. CONCLUSIONS: These results highlight the significance of psychological maltreatment in the relationship to the self-conscious emotions of guilt and shame. As in earlier studies, shame has been consistently correlated to poor psychological functioning, while guilt appears to be relatively unrelated to pathological functioning.  相似文献

This paper describes the experience of change management observed as part of an evaluation of the Transforming School Workforce Pathfinder Project commissioned by the UK Government for the English education system. The 32 Pilot Schools made interventions in organisational practice in ways that required them to think differently about work. Changes in the number, type and deployment of the school workforce combined with thinking about the nature of work have challenged existing practices. In particular, a focus on change management teams drawn from the whole school workforce, supported by an external school workforce advisor, has required schools to examine the nature of decision-making and participation. We intend to draw on evidence from eight case study schools and through this examine the implications for how change is understood and practiced. We critically engage with the government’s preference for a particular model of change to bring about organisational improvement, and we reveal a pluralistic and dynamic field both within practice and theorising.

Water-deprived rats served in seven conditioned lick suppression experiments designed to assess the effects on responding to a target CS of a series of unsignaled USs given in the training context following completion of CS training. Such treatment has been hypothesized to increase (inflate) the associative strength of the background cues from training (putatively, the CS’s comparator stimuli), thereby reducing responding to excitatory CSs and increasing the inhibitory potential of inhibitory CSs. Although posttraining extinction (deflation) of the CS’s comparator stimuli usually decreases inhibitory potential and increases excitatory potential of the target CS, posttraining inflation of the comparator stimuli had no effect on either excitatory responding to the target CS or summation test performance indicative of conditioned inhibition. This outcome was consistently obtained across a number of training, inflation, and test conditions selected to maximize sensitivity to any possible effects of comparator inflation. Implications of these null results for the comparator hypothesis of conditionedresponse generationare discussed.  相似文献

The modulatory effect of conditioned opioid analgesia on learning in the US-preexposure paradigm was examined in three experiments using water-deprived rats. In Experiment 1, it was found that tailflick latencies increased immediately after the rats were exposed to a context in which footshock had previously been administered. Prolonged nonreinforced exposure to the context attenuated this analgesia. Experiment 2 tested the possibility that the effectiveness of CS-US pairings in an excitatory context might be reduced by a conditioned analgesic response that lessens the perceived intensity of the US. Administration of the opiate antagonist naloxone prior to CS-US pairings in the excitatory context reduced the US-preexposure deficit—that is, the retarded response to the CS—but did not eliminate it, suggesting that part of the observed deficit resulted from conditioned activation of the endogenous opioid system. In Experiment 3, it was found that exposure to the excitatory context immediately prior to a CS-US pairing in an associatively neutral context resulted in a conditioned response deficit, indicating that the analgesia elicited by the excitatory context was sufficient to reduce US effectiveness. In combination with other recent reports, these results suggest that the associative deficit resulting from preexposure to a shock US may, in certain instances, represent the sum of several different associative processes.  相似文献

This paper is based on semi‐structured interviews with 59 Year 2 teachers across 45 schools in one LEA. It documents their practice of and attitudes to teacher assessment and it proposes a developmental model which describes and explains their approaches. The assessment of process skills is analysed and the effects of assessment on children's learning and teachers’ practice are discussed. The manageability of teacher assessment is also examined. The findings are linked with previous and subsequent studies on teacher assessment and suggestions for further research, based on these outcomes, are offered.  相似文献

In this invited article, we present an ongoing research program in the area of writing. Although this program has focused on students with learning disabilities (LD) and other struggling writers, it has also concentrated more broadly on issues involving writing development and general writing instruction. One purpose of this review was to share our basic findings in each of these areas, as they have important implications for teaching writing to students with LD. Another purpose was to illustrate how an ongoing research program develops and grows over time. To make this process more concrete, we employed several different literacy devices, including drawing an analogy between the development of our research program and the development of the story line for Star Trek II: The Wrath of Khan. Our final purpose was to describe the research we plan to do in the near future.  相似文献
