The convergence of Internet technology and federal information policy are encouraging federal information producers and users to adopt a new direct model of information dissemination of federal information from producing agency to end user. On the surface, this trend would appear to remove the traditional middlemen—the U.S. Government Printing Office (GPO) and depository libraries—from the dissemination model. To assess the impact of the Internet model on the future viability of the Federal Depository Library Program (FDLP), the traditional GPO/depository library model of information dissemination is examined in four areas, keeping in mind the underlying intent of the FDLP to assure access to federal information in all congressional districts. 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

Although institutional repositories (IRs) have become widespread, they have been consistently under-populated and under-utilised. Unless their content approaches a significant percentage of a university's output, IRs can neither form a useful branch of open access to scholarly communications, nor provide a representative view of an institution's research output. The UK's 2021 Research Excellence Framework (REF) requires all work submitted to it to have been deposited in a repository, which for most authors would mean an IR. This research sought to understand the impact of the REF mandate upon researchers and repository staff, and upon their relationship with the university, through a series of semi-structured interviews with researchers and repository managers. The research discovered that despite steep rises in repository submissions, little resource has been made available to accommodate hugely-increased workloads, nor have interfaces improved. Researchers and repository-managers alike struggle with a tedious and difficult administrative task that may require many iterations to complete. The research concludes that the mandate, and the pressure it places on the relationship between the researcher and the institution, is highlighting unspoken tensions in this relationship. Although the mandate is increasing the amount of open access material in the UK, as well as providing universities with evidence for the REF, it is placing significant strain on the tacit contract between a researcher and their employer. Opportunities to align the participants, to create alternative metrics from newly available data, and to develop new solutions, are being missed. This has implications for the way other mandates focusing on deposit in IRs are managed, both within and beyond the UK. 相似文献

This study employed the uses and gratification approach to investigate how journalists perceive relational satisfaction with the public on Twitter, specifically the associations between journalists’ motivations to use Twitter, their Twitter use, and their relational satisfaction with the public. Through a survey of South Korean journalists, this study revealed that journalists’ motivations for Twitter use are positively related to their job-related activities on Twitter (e.g., posting/sharing their news and interacting with audience), which consequently influences perceived relational satisfaction with the public. The findings provide new insight into an increasingly important part of the public’s engagement and news/information flows in the digital media environment. This study expands upon the literature by analyzing how journalists’ motivations for using Twitter and their job-related activities on Twitter are associated with relational satisfaction with the public. 相似文献

The local controversy over Cordoba House or the “Ground Zero Mosque” peaked at a May 2010 Lower Manhattan Community Board meeting that was open to the public. Examining the tolerance rhetorics evoked both for and against Cordoba, this paper argues that both tolerance rhetorics function differently to re-center the white non-Muslim subject and to structure inclusion and belonging within the nation. Extending the literature of tolerance, which tends to focus on the discourse of normative subjects, I analyze the tolerance rhetorics of two Muslim-American rhetors whose testimonies reveal the tensions, contradictions, and complicities involved in claims of national belonging. 相似文献

Television's liveness has long been seen as one of its key features. This paper argues that “liveness” is not a textual feature, but a more fundamental category (in Durkheim's sense) that contributes to underlying conceptions of how media are involved in social organization through their provision of privileged access to central social “realities.” This ideological view of liveness (cf. Jane Feuer's early work) is then extended in two ways: first, to consider two new forms of “liveness” that do not involve television (online liveness via the Internet and “group liveness” via the mobile phone); and second, by connecting liveness with Bourdieu's concept of habitus, and thereby linking “liveness” (including in its extended senses) with other parts of the materialized system of classification through which we make sense of the everyday world. 相似文献

Using the coordinated management of meaning theory as a guide, this article examines critiques and commendations of toy company, GoldieBlox Inc.’s, goal of “disrupting the pink aisle.” Notwithstanding capitalistic enterprise, it is argued that GoldieBlox’s corporate narrative engages in an imperative social skill that its toys still lack: critical reflection. Although GoldieBlox’s toys are rudimentary in their science, technology, engineering, and math designs, the company’s corporate narrative—driven by its origin story, mission and vision statements, and marketing strategies—challenges a 100-year-old gendered toy tradition and prompts significant questions of gender representation and improbable beauty ideals in our children’s toys. 相似文献

Three pioneer radio rating services contributed to the development of basic audience measurement concepts, which have become part of a standardized ratings vocabulary. Archibald Crossley gave to radio and, later TV measurement, its most basic term, rating. Claude E. Hooper made Hooperatings a part of the nation's vocabulary and contributed the available audience base and the average minute rating. Arthur Nielsen Sr., designed the first probability sample. In the long term, Nielsen's most important innovation was his projectable ratings. As a result, Nielsen championed CPM theory, which tied advertising prices to audience size. Nielsen also was the first to provide a wealth of analytical detail, such as reach, frequency, and audience flow. 相似文献

Subjects differing in interpersonal construct differentiation completed a measure of religious attitude, a measure of attitudinal confidence, and a 20‐item religious behavior self‐report inventory. High‐confidence subjects exhibited greater attitude‐behavior consistency (r = .69) than did low‐confidence subjects (r = .51). Despite high power (N = 313), high‐ and low‐differentiation subjects did not differ significantly (r = .61 and .66, respectively), indicating that the role of differentiation as a direct mediator of non‐interpersonal attitude‐behavior consistency is a comparatively small one. But the influence of attitudinal confidence on attitude‐behavior consistency was larger for low‐differentiation subjects (r = .75 for high confidence, .51 for low) than for high‐differentiation subjects (r = .68 for high confidence, .50 for low), suggesting that interpersonal construct system development may indirectly influence the relationship of non‐interpersonal attitudes and behaviors. 相似文献

The 1930s represent a contentious period between the radio and newspaper industries. In the middle of the press-radio war, a new technology, the broadcast radio facsimile, emerged with the potential to bring together the warring industries. Although the radio facsimile was short lived, its story, seen through the lens of the press-radio war, provides an interesting look at the forces shaping a new technology.Envisioned as a technology that would allow subscribers to receive the newspaper via a radio receiver, the facsimile presented an interesting dilemma: Who would control the creation and dissemination of news—the newspaper or radio industry? This article explores this question through an examination of industry narratives about the facsimile. In analyzing the discourses, this study focuses on how the newspaper and radio industries envisioned the future of the facsimile. Was the facsimile viewed as a means for cooperation or as a point of contention? 相似文献

The purpose of this study is to understand a citywide initiative to increase diversity and inclusion in a predominantly white US city with a tragic racial history. This research reveals prevailing struggles with communicating about diversity and race and taking meaningful actions to promote social change. Using theories of difference and dialogue, we analyze in-depth, qualitative fieldwork with three voluntary organizations: The Chamber of Commerce; The Network; and Minorities in Business. Our work answers calls to center race and embodied differences and extends theorizing on dialogic sensibilities. The findings reveal that difference organizes dialogue through: (1) the ongoing construction of context; (2) the mobilizing of social change efforts; and (3) the intermingling of economic and racial justice discourses. Ultimately, we hope this work encourages further conversation about difference, race, and engaged scholarship. 相似文献
