More and more newspaper and magazine Web sites offer paid content. However, selling information goods at a price higher than the marginal cost means finding a strategy for product or price differentiation. A possible strategy to solve this problem is the bundling of information goods. In this article, we analyze empirically, with quantitative statistic methods, strategies for selling bundled and unbundled content on newspaper and magazine Web sites. This analysis is based on the theoretical approach of Bakos and Brynjolfsson (1996). The article shows that a cannibalization takes place if the same bundle of information goods is offered in offline (printed) and online (digital) media at the same time. Traditional bundling models work nonetheless in an online media if the online content is rebundled (e.g., as dossiers about a topic), but thereby do not compete with the printed version.  相似文献

The present investigation addresses the question of whether certain factors can protect high-achieving students at risk for being labeled a nerd against devaluation. In 2 studies, 125 and 317 students from Grade 8 evaluated vignettes describing average students and students who were called “nerds.” Results indicate that being modest about good grades, being engaged in sports, and being sociable led to higher liking. In students who were labeled nerds, but not in average students, display of effort led to less favorable evaluations. The effects of the aforementioned factors were moderated by the gender of the perceivers and targets. Findings are discussed with respect to gender-role stereotypes and the self presentation of high-achieving students.  相似文献

Previous team role taxonomies have largely relied on self-report data, have focused on functional roles and have described individual predispositions or personality traits. Instead, this study takes a communicative approach and proposes that team roles are produced, shaped and sustained in communicative behaviors. To identify team roles communicatively, 59 regular organizational meetings were videotaped and analyzed. Cluster analysis revealed five emergent roles: the solution seeker, the problem analyst, the procedural facilitator, the complainer, and the indifferent. In terms of meeting outcomes, solution seekers were beneficial to idea longevity, whereas complainers were harmful for meeting satisfaction and idea longevity. Future research directions and managerial implications are highlighted.  相似文献

This article investigated and evaluated the changes which have occurred in Australian football since the publication of the Crawford Report in 2003. Prior to this report, it was widely perceived that football was the ‘sleeping giant’ of Australian professional sport despite its popularity at youth participant level. The Crawford Report made a range of recommendations and a new era was heralded when Football Federation Australia was established which set upon the task of adopting a number of Crawford’s recommendations. To investigate the impact of the Crawford Report on the current status of Australian football, a qualitative methodology was adopted. Purposive sampling was adopted to give voice to senior football figures who were involved in the sport in both the pre- and post-Crawford Report periods and a total of 15 semi-structured interviews were conducted. A number of significant themes emerged from the research. All participants agreed that Australian football’s appeal has been broadened. However, the interviews also reported that the perception of football as a minor code and always relegated to the ethnic margins was a ‘myth’. Also, the participants raised the issue of whether the Crawford Report was implemented to its fullest degree. They were passionate about the idea that if all recommendations were implemented, the sport might currently be in a much stronger position.  相似文献

Abstract

While leisure writing may help children to acquire writing skills, it can also be considered as an inherently valuable cultural activity. This study explores how children’s beliefs may explain to what extent children are inclined to leisure writing and if there are any gender differences. Building on preliminary scale development work, we analysed data from 963 third-graders. Variables included (a) the intrinsic value attached to leisure writing (b) preceding behavioural, normative, and control beliefs related to these activities, and (c) the level of leisure writing. In a structural equation model, the preceding beliefs were applied as explanatory variables for the intrinsic value. Intrinsic value, in turn, explained a large proportion of variance in children’s leisure-writing activities. Gender differences in leisure writing were mediated by intrinsic value. Significance of intrinsic value and preceding beliefs regarding leisure-writing activities are discussed.  相似文献

There are many benefits to peer and near-peer tutoring. The current literature suggests that near-peer teaching within the domain of gross anatomy may lead to the development of numerous competencies for burgeoning medical professionals. The aim of this study was a quantitative and qualitative approach to explore which professional and personal competencies anatomy tutors developed as a result of their teaching activities in a gross anatomy course at a medical school in Germany. For a period of 18 months, 24 peer tutors were followed and queried multiple times via questionnaire and semi-structured interviews. It was found that most of the skills tutors developed or strengthened over one semester matched most of the core competencies described in various official competency frameworks used for physician education. In particular, tutors thought that tutoring gross anatomy had improved their knowledge of professional behavior as well as their communication skills. They also felt that they had learned to take on more responsibility and to use available resources more effectively. Overall, tutoring gross anatomy was perceived as very challenging, but also very rewarding, mainly because it provided the opportunity to develop and strengthen important skills such as self-confidence, self-awareness, positive thinking, self-insight, and stress management. Ultimately, these are all factors that contribute to resilience, an important attribute for physicians.  相似文献

Parents with a migration background are underrepresented among parent representatives at schools in Germany. However, increased involvement of these parents is essential for a lively democratic culture. To explore the motivations of parents with migration background regarding their school involvement, interviews with N?=?31 parent representatives with migration background were content analysed, starting deductively from a set of categories according to the theory of planned behaviour. In the analysis, the main category ??attitude?? was deductively subdivided into ??motivation in the course of action/intrinsic value??, ??results and consequences regarding own interests?? and ??results and consequences regarding others/altruistic motivation??. ??Subjective norm?? was inductively differentiated into ??other parents??, ??teachers and leadership team?? and ??other persons/perceived general expectations??; ??perceived behavioural control?? was differentiated into the subcategories ??assertiveness and freedom from anxiety??, ??language competence??, ??socioeconomic background??, ??availability of time??, ??setting in school and school district?? and ??field expertise and know-how??. Additionally, ??habit?? was deductively established and retained as a main category. Analysis of 513 statements resulted in an interrater-agreement of ???=?0.82. Implications for working with parents in an intercultural context are discussed.  相似文献
