We present an empirical analysis of product differentiation using a new panel data set on film-programming choice in a major
U.S. metropolitan motion-pictures exhibition market. Using these data, we compute two measures of product similarity, which
allow us to investigate the determinants of strategic product differentiation in a multi-characteristics space. Our evidence
is consistent with the idea that the degree of product differentiation between theatre pairs reflects a balance between strategic
concerns and contractual constraints. Similarity in one dimension is offset by differentiation in others. Our results further
suggest that the degree of product differentiation is negatively related to market size. Finally, we find that ownership matters:
theatres under common ownership make more similar programming choices than theatres with different owners. 相似文献

This article looks at the evolution of retirement preparation for male professional rugby union athletes in the English Premiership. Rugby union became a professional sport in 1995 allowing rugby to become a stand-alone career. This alteration in employment structure resulted in stronger athletes, thus resulting in an increase of injury making a career in sports more uncertain. In an effort to address the growing concern of injury-induced retirement, the Rugby Players’ Association’s created the Benevolent Fund1 in 2001. The Foundation was to provide assistance to players during times of injury and provide educational opportunities to assist in career transition. This article highlights how the transition to a professional game created the ‘Quad-Lemma’ of rugby injury and how the Rugby Players Association was created to address the welfare concerns of the new professional format of rugby union. 相似文献

ABSTRACTAs staffing models evolve for academic library service points, online chat reference services require strategic analysis to improve efficiency and effectiveness. This paper will examine the perception of chat reference before and after staffing changes from faculty librarians, staff, and graduate assistants to non-MLIS library professionals and graduate assistants at Florida State University’s a large, public research university library. Our survey explores satisfaction levels and perception of both patrons and library personnel before and after the staffing change.Our analysis of 197 patron survey results determined that patrons are equally satisfied with non-librarian provision of chat reference services and found chat interactions to be comparable in quality and timeliness to chats staffed by librarians. Our research into staffer survey results revealed a slight decrease in satisfaction with operation of the service, notably in terms of confidence after the staffing transition even though this was not reflected in the patron satisfaction levels. This assessment indicates that library workers are equally as competent in staffing chat reference services as librarians from patron perspectives. As academic libraries continue to measure the value of staffing service desks with librarians, this study will provide relevant insight into how patrons and staffers are affected by changes in staffing models. 相似文献

Cognitive activities in complex science text and diagrams 总被引:1,自引:0,他引:1

Ainsworth’s (2006) DeFT framework posits that different representations may lead learners to use different strategies. We wanted to investigate whether students use different strategies, and more broadly, different cognitive activities in diagrams vs. in running text. In order to do so, we collected think-aloud protocol and other measures from 91 beginning biology majors reading an 8-page passage from their own textbook which included seven complex diagrams. We coded the protocols for a wide range of cognitive activities, including strategy use, inference, background knowledge, vocabulary, and word reading. Comparisons of verbalizations while reading running text vs. reading diagrams showed that high-level cognitive activities—inferences and high-level strategy use—were used a higher proportion of the time when comprehending diagrams compared to when reading text. However, in running text vs. diagrams participants used a wider range of different individual cognitive activities (e.g., more different types of inferences). Our results suggest that instructors might consider teaching students how to draw inferences in both text and diagrams. They also show an interesting paradox that warrants further research—students often skipped over or superficially skimmed diagrams, but when they did read the diagrams they engaged in more high-level cognitive activity. 相似文献

Achieving change through mutual development: supported online learning and the evolving roles of health and information professionals 总被引:1,自引:1,他引:0
Introduction: Major changes in health care, within an information‐ and technology‐rich age, are impacting significantly on health professionals and upon their education and training. Health information professionals—in both the National Health Service (NHS) and higher education (HE) contexts—are consequently developing their roles, skills and partnerships to meet the needs of flexible education and training. This article explores one facet of this—supported online learning and its impact on role development. Methodology: A case study approach was taken, aiming to explore how academics, health information professionals and learning technologists are developing supported online learning to explicitly address the e‐literacy and information needs of health students within the context of NHS frameworks for education. This was contextualized by a literature review. Results: The case study explores and discusses three dynamics—(i) The use of supported online learning tools by future health‐care professionals throughout their professional training to ensure they have the appropriate e‐literacy skills; (ii) the use of supported online learning by current health professionals to enable them to adapt to the changing environment; (iii) the development of the health information professional, and particularly their role within multi‐disciplinary teams working with learning technologists and health professionals, to enable them to design and deliver supported online learning. Conclusions: The authors argue that, in this specific case study, health information professionals are key to the development of supported online learning. They are working successfully in collaboration and their roles are evolving to encompass learning and teaching activities in a wider context. There are consequently several lessons to be drawn in relation to professional education and role development. 相似文献

Hydrogels are networks of hydrophilic polymer chains that are swollen with water, and they are useful for a wide range of applications because they provide stable niches for immobilizing proteins and cells. We report here the marriage of hydrogels with digital microfluidic devices. Until recently, digital microfluidics, a fluid handling technique in which discrete droplets are manipulated electromechanically on the surface of an array of electrodes, has been used only for homogeneous systems involving liquid reagents. Here, we demonstrate for the first time that the cylindrical hydrogel discs can be incorporated into digital microfluidic systems and that these discs can be systematically addressed by droplets of reagents. Droplet movement is observed to be unimpeded by interaction with the gel discs, and gel discs remain stationary when droplets pass through them. Analyte transport into gel discs is observed to be identical to diffusion in cases in which droplets are incubated with gels passively, but transport is enhanced when droplets are continually actuated through the gels. The system is useful for generating integrated enzymatic microreactors and for three-dimensional cell culture. This paper demonstrates a new combination of techniques for lab-on-a-chip systems which we propose will be useful for a wide range of applications. 相似文献

This paper presents an empirical assessment of movie-theatre attendance in two major metropolitan markets and provides strong support for the importance of spatial characteristics in determining attendance. We consider the hypothesis that attendance at a particular movie theatre reflects a tension between two effects: a negative competition effect and a positive agglomeration effect. We find evidence that the competition effect dominates. Further, we identify a pattern of systematic spatial decay in the impact of this effect on demand. 相似文献

Bullying poses a threat to children's social‐emotional functioning and their perceptions of school climate, yet few studies have examined different types of social‐emotional and behavior problems presented by children involved in bullying, as a bully, victim, or bully/victim across multiple school levels. The current study used data from 24,345 elementary‐, middle‐, and high‐school students to examine the association between frequent involvement in bullying and aggressive impulsivity, attitudes toward aggressive retaliation, internalizing symptoms, peer relations, and perceptions of school climate. Logistic regression analyses indicated that bully/victims were most likely to display internalizing symptoms, problems in peer relationships, and have poorer perceptions of the school environment. Both frequent bullies and bully/victims displayed aggressive‐impulsive behavior and endorsed retaliatory attitudes. High‐school students frequently involved in bullying tended to display the greatest risk for internalizing problems, but less risk for aggressive impulsivity. Developmental trends and implications for prevention and early intervention are discussed. © 2008 Wiley Periodicals, Inc. 相似文献

The modern workforce is becoming increasingly older, and because of this demographic shift, intergenerational interactions are more common. However, these interactions are often described negatively and could be exaggerated when housed in a workplace setting. This study explores intergenerational communication in the increasingly diverse nursing profession through the lens of communication accommodation theory. Specifically, 32 nurses were interviewed in order to understand how they experience and describe intergenerational communication in the healthcare context. Through an abductive approach to data analysis, we found three interrelated findings: (a) intergenerational hostility is commonplace, (b) intergenerational hostility is socialized, and (c) nurses are viewed as a dispensable resource. These findings were communicated and justified through the colloquialism “nurses eat their young.” Theoretical implications related to communication accommodation theory and the Communication Predicament Model of Aging were developed along with practical suggestions that focus on ways to disrupt the acceptance of intergenerational hostility, enhance intergenerational communication in the workplace, and create a space for structural change. 相似文献
