This paper explores organizational and peer dynamics that impact the potential for productive, trusting peer relationships. An in-depth phenomenological study of five peer coaching dyads was undertaken to examine the establishment and maintenance of peer coaching. Joint interviews were used to promote co-construction of responses. Findings suggested that formation of trust is impacted by values-based attachment, confidentiality, and the capacity of peers to make themselves vulnerable. Individual bonds are important at the start of coaching, but trust is further strengthened through contracting and reciprocity within the relationship itself and by an open culture within the organization. Organizational culture was found to influence trust and the need for a combination of benign organizational support, transparency, and non-intervention was seen as vital.  相似文献

This paper describes aspects of the real and hidden shortage of mathematics teachers. Possible causes of teacher shortage are discussed: salary levels, the image of teaching as a career, the image of mathematics, the diversion of mathematicians into the teaching of computing, and promotion of mathematicians into administrative positions. The effects of shortage on mathematics departments are also considered, in particular the effects on curriculum development, the role of the head of department, overloading of mathematics teachers, and the consequences of teacher shortage for certain pupil groups. With the current focus of attention on teacher shortage in certain subject areas, the paper raises a number of important points.  相似文献

This study examines audience duplication, the extent to which the audience of one program also watches the other, and its determinants. Using peoplemeter data from Guangzhou, a multichannel and multicultural television market in China, the study tests the intertwining effects of media structural factors and audience preference factors on audience duplication levels of program pairs. The results show significant effects of the two types of factors. A regression model was established in which these two types of factors together explained 59% of the total variance in audience duplication.  相似文献

This study adopts a network analytic approach to understand media audiences in relation to media markets, bridging the literature on audience behavior and media economics. Using audience data in the Chinese and U.S. markets, we apply multi-level measures to compare audience fragmentation patterns, a key indicator of market structure, across television channels. Drawing on McQuail's four–stage fragmentation model, we find the Chinese television market exhibits the Core-Peripheral model where a few channels dominate the marketplace and the rest are viewed by niche segments of the audience. In contrast, the U.S. market represents the Pluralism model with extremely high levels of audience duplication across channels, suggesting overlapping patterns of exposure throughout the market rather than isolated segments.  相似文献

Editorial     
This study hypothesized a Socratic effect for the receiver's perceptions of the consequences of a proposal which were not mentioned by a persuader. Unlike earlier research, this study employed affective‐cognitive consistency theory since the perceptions of consequences were related psychologically, not logically. The analysis generally supported the speculations concerning belief‐ and attitude change.  相似文献

This study adapts Giddens' structuration theory to assess audience agency and its relationship with media structures. It employs network analysis to examine the co-evolution of audience duplication patterns and elements of media structure in China's national television market. The findings reveal that Chinese audiences tend to gravitate to channels with greater market share, higher household penetration rates, and more drama programming. Furthermore, channels tend to adjust their levels of drama programming relative to patterns of audience duplication in the long run. Finally, there was evidence of higher-order patterns of audience behavior, suggesting the existence of channel repertoires, and market concentration.  相似文献

The user experience is an integral component of interactive information retrieval (IIR). However, there is a twofold problem in its measurement. Firstly, while many IIR studies have relied on a single dimension of user feedback, that of satisfaction, experience is a much more complex concept. IIR in general, and exploratory search more specifically, are dynamic, multifaceted experiences that evoke pragmatic and hedonic needs, expectations, and outcomes that are not adequately captured by user satisfaction. Secondly, questionnaires, which are typically the means in which user’s attitudes and perceptions are measured, are not typically subjected to rigorous reliability and validity testing. To address these issues, we administered the multidimensional User Engagement Scale (UES) in an exploratory search environment to assess users’ perceptions of the Perceived Usability (PUs), Aesthetics (AE), Novelty (NO), Felt Involvement (FI), Focused Attention (FA), and Endurability (EN) aspects of the experience. In a typical laboratory-style study, 381 participants performed three relatively complex search tasks using a novel search interface, and responded to the UES immediately upon completion. We used Principal Axis Factor Analysis and Multiple Regression to examine the factor structure of UES items and the relationships amongst factors. Results showed that three of the six sub-scales (PUs, AE, FA) were stable, while NO, FI and EN merged to form a single factor. We discuss recommendations for revising and validating the UES in light of these findings.  相似文献
