A generation of broadcasters has grown up without a firsthand knowledge of the now‐out‐of‐print FCC “Blue Book.” Mr. Meyer's personal overview of the content and effects of this document will be followed by a future article on “Reaction to the ’Blue Book’.” It is accepted that any one individual's summary of a controversial document will itself be controversial. Richard J. Meyer is Assistant Professor and Director of Educational TV at the University of Wichita, and wrote the MA thesis on which this article is based under the direction of Professor Stanley Donner at Stanford University. He also has worked in broadcasting at stations KZSU, KSAN‐TV and KQED (TV). 相似文献

Libraries will be changed by technological and social developments that are fueled by information technology, bioinformatics, and networked information. Libraries in highly focused settings such as the health sciences are at a pivotal point in their development as the synthesis of historically diverse and independent information sources transforms health care institutions. Boundaries are breaking down between published literature and research data, between research databases and clinical patient data, and between consumer health information and professional literature. This paper focuses on the dynamics that are occurring with networked information sources and the roles that libraries will need to play in the world of medical informatics in the early twenty-first century. 相似文献

A library training workshop is an effective way to teach and expand staff skills and, in the process, create interest in new library-related procedures. Hosting a workshop presents an opportunity to cultivate shared knowledge internally, and inviting outside participation provides a forum for strengthening external relationships and exchanging ideas. This article offers a detailed look at organizing a workshop—from budgeting and selecting a trainer to registering participants and making local arrangements. Additionally, it offers practical guidance for successfully planning and organizing a training workshop that will be a rewarding experience for participants, trainer, and host. 相似文献

‘Yaddo’, recalled composer Aaron Copland, ‘became so much a part of my life that I tend to forget how strange the name sounds to those not familiar with it.’ By its very delineation, vagary of purpose, and posture of cloistered withdrawal, Yaddo is defined by a meticulously cultivated and carefully guarded tradition of community and cultural identity; one that was carefully preserved (and, in turn was informed by) the formation of an archive. My point of query centers on the particular consequences of the bond between historical trace and physical place being severed (as perhaps it always must be) when the very materiality that informs an institution’s ‘memory’ is irrevocably distanced. 相似文献

An analysis of 9 week-long samples of prime-time network programming broadcast between the fall of 1997 and the fall of 2003 found that more than 8 out of 10 programs were labeled with an age-based rating (TV-G, TV-PG, TV-14, or TV-MA), whereas fewer than 4 in 10 programs were also labeled with content-based ratings (V, S, L, or D). Although programs with age- and content-based ratings accurately reflected sexual and violent content, a sizable number of programs without content-based ratings also had sexual and violent content. Ratings provide parents with incomplete information on which to base viewing decisions. 相似文献

This study examined changes in members' satisfaction with group processes as they worked together over time to complete a series of seven group tasks. Members of 10 groups (N=58) communicated with each other using a computer‐based collaborative technology over a 10‐week period. Satisfaction with group processes was partitioned into individual and group levels with Hierarchical Linear Modeling, and information quality and contribution equity were introduced as predictors of satisfaction. Findings indicated that (1) individuals' satisfaction increased over time; (2) the quality of information acquired from group members and the equity of contributions among members positively affected satisfaction after completion of the first group task; (3) information quality did not significantly affect the rate of changes in satisfaction, whereas contribution equity did; and (4) when individuals' contributions and others' average contributions were used as separate predictors of satisfaction, individuals' contributions were negatively related to satisfaction, but others' contributions were positively related to an individual's satisfaction. 相似文献

The purpose of this study was to examine sibling communication satisfaction, with a specific focus on interpersonal solidarity, individualized trust, and self‐disclosure. Respondents (N = 360) were asked to report on a relationship with either an older sister, younger sister, older brother, or younger brother. Results indicate that interpersonal solidarity is the largest predictor of sibling communication satisfaction, followed by individualized trust, and self‐disclosure. 相似文献

Signage represents more than directions or policies; it is informational, promotional, and sets the tone of the environment. To be effective, signage must be consistent, concise, and free of jargon and punitive language. An efficient assessment of signage should include a complete inventory of existing signage, including an analysis of the types of signs, its location, language, and its design. This article outlines the steps involved in a comprehensive signage audit, which along with a literature review, provides the foundation for creating a signage policy, best practices guidelines, and a branding strategy for future signage. 相似文献

Information adequacy,job satisfaction and organizational culture in a dispersed‐network organization
This investigation examined the relationship of information adequacy to job satisfaction and organizational culture in a healthcare organization with both office and field personnel. Information adequacy was assessed in four areas: personal performance, organizational policies, organizational performance, and organizational objectives. Comparisons of field and office personnel indicated that they did not differ on information adequacy or job satisfaction; they did, however, differ on several dimensions of organizational culture. Also, the relationship of information inadequacy to job satisfaction and organizational culture differed for employees depending on whether they worked primarily in the field or primarily in the office. Implications of the findings are drawn for organizations with a dispersed‐network structure. 相似文献

This investigation reported normative data for experienced (N = 20) and less‐experienced (N = 20) college teachers’ use of humor, self‐disclosure, and narrative activities. Results indicated that both groups of teachers observed in the study incorporated the three behaviors within their 50‐minute lectures. Experienced teachers, however, used humor, self‐disclosure, and narrative activities more frequently than the less‐experienced teachers. Additionally, the experienced teachers used the behaviors to clarify course content. 相似文献

Prison newspaper stories capture the quotidian atmosphere of the penitentiary as it is lived and understood by people confined there. This article analyzes a newspaper produced since 2001 at a state prison for women in the northeastern United States. The publication comes out of a journalism class taught by the author and a colleague, and is produced entirely by inmates of the prison. After situating the prison newspaper as a tool of ideological struggle, the article uses symbolic convergence theory to provide a fantasy theme analysis of the texts and to illuminate the rhetorical vision they create for their authors and audiences. The newspaper expresses inmates' struggles to overcome the degradations of confinement with spirituality, compassion, pragmatism, and even humor. 相似文献

This case study describes the creation of a leisure reading collection in the Clifford Whitworth library at the University of Salford. It briefly surveys existing literature on leisure reading collections and looks at the growing interest among U.K. academic libraries in recreational reading. It considers the reasons for promoting reading as a leisure activity to students and describes the processes of selecting, purchasing, and marketing the collection at Salford. It also considers possible future developments for the collection and the evaluation of the library's attempts to encourage a culture of reading among Salford students. The positive response to the collection suggests the development of leisure reading is a worthwhile activity for academic libraries to focus on and the study contains useful information for others who are interested in creating a similar collection. 相似文献

We show that the h-index, g-index, ψ-index, and p-index, are related through the inequalities: h ≤ p ≤ g ≤ ψ. Moreover, this relation is proved theoretically in the mathematical framework of Lotkaian informetrics and is verified empirically by using two datasets from the Web of Science in the fields of electrochemistry and gerontology. For quantifying their relations, we estimate the g-index, ψ-index, and their cores and ratios of cores via a second-order Taylor series when the e-index, h-index, and C1 (the maximum number of citations received by a paper) are known. Then we find for the two empirical cases, that ratios of cores and average citations are approximately stable. Compared with the g-index, the offset-ability of the h-index decreases by 20% but the average citations increase by 20%. A similar observation holds for the comparison of the g-index and ψ-index. To explore the possible applications of cores of different indices, we apply them to extract the core structure of a network. The h-core is the most efficient, while the ψ-core includes more nodes with high betweenness. 相似文献

This experiment assessed whether instructor credibility (low or high) moderated the effects of grade incentives (rewards or punishment) and advantage framing (gain or loss) of technology policies on students’ intent to comply and motivation to learn. Results indicate that credibility increased motivation to learn. Significant moderated moderated mediation was found: a three-way interaction affected both intent to comply, and motivation to learn as mediated by attitude toward the policy. Specifically, credibility positively influenced learning outcomes via attitude when the syllabus used opposing frame-incentive structure (i.e., gain-framed punishment and loss-framed reward). 相似文献

People spend an increasing amount of time using social media systems to network, share information, learn, or engage in leisure activities (e.g., gaming). Libraries too are establishing a social media presence to promote the library and provide services to user populations through the social media systems the users frequent. This study explores Twitter uses by six large academic libraries and factors that make library tweets useful. 752 tweets were analyzed by topic to develop a subject typology of library tweets. In addition, tweets and Twitter user characteristics were analyzed to explore what makes library tweets useful, as measured by the number of retweets and favorites received. Content analysis of the samples of library tweets revealed nine content types, with the event and resource categories being the most frequent. In addition, the analysis showed that tweets related to study support services and building and maintaining connections with the library community were the most frequently retweeted and selected as favorites. The presence of a URL in the tweet was positively associated with the number of retweets, and the number of users followed was positively associated with the number of favorites received. Finally, a negative correlation was found between the account age and number of favorites. 相似文献

This article explores the possibility of journalists acting as custodians of critical engagement, drawing on Rancière's conception of dissensus as organized disagreement over the conditions of understanding. It begins by assessing the status that worthiness and naiveté have as negative symbolic capital in the journalistic field, before asking whether journalists' ambivalent detachment from the objects of their inquiry hinders their ability to engage critically with experts in other fields. It argues that journalism's role in marshaling dissensus amounts to making clear the limits and absences of intelligibility in journalism and other fields, in distinction to disseminating knowledge as such. 相似文献

Salt decay is one of the harshest, most frequent, and more complex types of decay of porous materials in built heritage, including natural stones, ceramics, and mortars. In this article, we address the mechanism of thermal expansion, which is one of the least studied, yet most controversial, of those proposed over time to explain salt decay. We present a review of scientific literature on the topic, followed by a study of the effects of thermal expansion on a specific material, the well-known Ançã limestone. The study included experimental measurement of the linear thermal expansion coefficient of the Ançã, both in its natural state and with varying contents of sodium chloride, sodium sulphate, or sodium nitrate. The results show that this coefficient: (i) is significantly higher when the stone is contaminated with salt; and (ii) scales approximately with the amount of salt contained in the stone pores, regardless of the type of salt. Based on these results and on modelling of damage modes at the microscopic and macroscopic levels, respectively, we conclude that thermal expansion can cause powdering, disaggregation, or other types of decay consisting of internal loss of cohesion. However, it is not likely to cause exfoliation of salt-loaded layers. 相似文献
