ABSTRACT Information technology developments over the past 3 decades have profoundly influenced university scholarship, but the relationship has been characterized by aspects of both continuity and change. This panel of presentations and ensuing discussion consider ways in which these developments drive changes in scholarly practice and present challenges for research libraries on issues such as interoperability or facilitating access in a networked environment. 相似文献

Abstract Entrepreneurship theory complements established approaches to media management research with an alternative frame for viewing media ownership and the media's capacity for content diversity. Established entrepreneurship metrics were applied to media industries in the United States. All media sectors experienced varying rates in the second half of the last century; by the turn of the new century, nearly all were more entrepreneurial than any other U.S. service or manufacturing industry. 相似文献

Collaborative filtering is a popular recommendation technique. Although researchers have focused on the accuracy of the recommendations, real applications also need efficient algorithms. An index structure can be used to store the rating matrix and compute recommendations very fast. In this paper we study how compression techniques can reduce the size of this index structure and, at the same time, speed up recommendations. We show how coding techniques commonly used in Information Retrieval can be effectively applied to collaborative filtering, reducing the matrix size up to 75 %, and almost doubling the recommendation speed. Additionally, we propose a novel identifier reassignment technique, that achieves high compression rates, reducing by 40 % the size of an already compressed matrix. It is a very simple approach based on assigning the smallest identifiers to the items and users with the highest number of ratings, and it can be efficiently computed using a two pass indexing. The usage of the proposed compression techniques can significantly reduce the storage and time costs of recommender systems, which are two important factors in many real applications. 相似文献

Film has become a popular form of entertainment among teenagers and provides images from which teens model behaviors and form attitudes. This study addresses the understudied area of the portrayal of teen and adult sexual behaviors over nearly three decades in the top-grossing teen-centered films from 1980 to 2007. This study analyzes the frequency, nature, character portrayals, and consequences of sexual behavior. The results show that teen-centered films are replete with passionate kissing and sexual dialogue yet contain a modicum of implied intercourse and intimate touching. Moreover, the frequency of such occurrences has remained surprisingly constant over the last three decades. This research also reveals that teen-centered films, as a source for sexual socialization, are relatively impoverished when it comes to responsible messages dealing with abstinence, safe sex practices, and the health risks associated with sex. 相似文献

This article analyzes the discourses of Latina/o identity embedded in the movie Frida, the Latino news coverage about the film, and an on-line chat stream about the film. Comparing the identity discourses circulated by the movie's producers, Latina/o journalists, and Latina/o audiences when discussing the film shows how different communities negotiate the meanings of ethnic identity. The study concludes that the discourses of ethnic identity circulated through the movie, news coverage, and chat stream disrupt notions of Latina/o ethnic identity as a stable and commodifiable demographic category. 相似文献

ABSTRACTThe goal of this research is to propose a new method of characterizing rammed-earth walls. Based on their historic building materials properties, five broad test groups were established for the characterization: chemical and mineralogical composition, physical properties, mechanical properties, particle size distribution, and dating. These determinations can, in turn, be grouped into two different types: instrumental techniques such as XRF, XRD, and SEM-EDX, as well as adaptations of standard methods (mainly UNE-EN standards) for application to these materials. As case studies where the proposed method is applied, we present our research on the rammed-earth walls in the ramparts of Seville and Malaga (Spain), clearly showing the method’s capacity for comparing and differentiating different rammed-earth walls. 相似文献

This article examines how superstars can influence moviegoers' decision process via eliciting emotions. The article builds upon prior research in the role of emotions in consumption. The data of a survey study are used to capture the emotional profile of superstars. Results from a correspondence analysis indicate that superstars can be classified according to the basic emotions they elicit. The resulting “constellations” of superstars influence spectators' decisions. A nested logit model gives evidence that supports the importance of taking into account the difference among emotions of the same valence. Moreover, the emotional interdependence between superstars seems to influence spectators' willingness to attend a movie. 相似文献
