General results on transformations on information production processes (IPPs), involving transformations of the h-index and related indices, are applied in concrete, simple cases: doubling the production per source, doubling the number of sources, doubling the number of sources but halving their production, halving the number of sources but doubling their production (fusion of sources) and, finally, special cases of general power law transformations. In each case we calculate concrete transformation formulae for the h-index h (transformed into h*) and we discuss when we have h* < h, h* = h or h* > h.

These results are then extended to some other h-type indices such as the g-index, the R-index and the weighted h-index.  相似文献

Recently Woeginger [Woeginger, G. H. (2008-a). An axiomatic characterization for the Hirsch-index. Mathematical Social Sciences. An axiomatic analysis of Egghe's g-index. Journal of Informetrics] introduced a set of axioms for scientific impact measures. These lead to a characterization of the h-index. In this note we consider a slight generalization and check which of Woeginger's axioms are satisfied by the g-index, the h(2)-index and the R2-index.  相似文献

The structure of different types of time series in citation analysis is revealed, using an adapted form of the Frandsen–Rousseau notation. Special cases where this approach can be used include time series of impact factors and time series of h-indices, or h-type indices. This leads to a tool describing dynamic aspects of citation analysis. Time series of h-indices are calculated in some specific models.  相似文献

Four large organizations, two each from the private and public sectors of the Northern Ireland economy, were selected for this study which, first, explored the effects of religion-based workforce difference on intergroup relationships, second, investigated the contribution of organizational sector to communicative differences, and third, gauged the effects of group-based negativity on the flow and distribution of functional information within the organization. Little evidence of intergroup conflict was found although employees expressed a desire for greater quantity and quality of outgroup contact. Significant differences between the private and public bodies emerged in this respect. Contrasts were consistent with general organizational differences typifying the sectors. Findings are discussed in relation to diversity management and the characteristics of organizational sectors.  相似文献

As more and more countries adopt access-to-information (ATI) laws to advance economic development and democratic self-governance, efforts are under way to foster ATI movements in the Arab world. While one nation in that region already has adopted the legislation, the likelihood of adoption in other Arab states is unknown. This comparative study analyzed 12 quantitative indicators measuring political, cultural, and economic factors associated with access to information. Results indicate that Arab countries, as a whole, contrast sharply in nearly all areas with non-Arab countries that have ATI laws and are consistent with non-Arab countries that do not have ATI laws. However, the study also found that the most recent ATI law adopters had weaker political, cultural, and economic enabling environments for government information access, which may portend a global phenomenon that will continue and could explain the interest in adopting the legislation in the Arab world. Findings also suggest that while a handful of Arab countries might have the wealth to effectively implement ATI laws, political and cultural conditions may be substantial obstacles for greater government transparency. Other results regarding the use of quantitative indicators of ATI adoption, particularly structural pluralism, are discussed.  相似文献

In the nineteenth century, imported wallpapers covered interior walls of Persian palaces and mansions, of which Vasiq-Ansari House in Isfahan, Iran, exhibits very highly elaborated examples. In this study, micro-Raman spectroscopy, scanning electron microscopy, energy dispersive X-ray spectroscopy, ultraviolet–visible spectroscopy, and light microscopy were used to identify pigments and other materials used in the wallpapers of Vasiq-Ansari House. Results indicated that chrome yellow, artificial ultramarine blue, brass metallic leaf, an organic red dyestuff (probably cochineal), and a copper-based green were used as colourants in the wallpapers. Different shades of brown were achieved by mixing various combinations of red lead, carbon black, and calcium carbonate. The white calcium carbonate was also used as a ground layer, applied to a paper support composed of bast and softwood fibres. Based on knowledge of the materials used, these wallpapers are most probably manufactured from the mid- to late-nineteenth century.  相似文献

ABSTRACT

During 2002 the Russian publishing industry and news media were under intense scrutiny, sometimes verging on assault, by government and pro-government groups. A new 20% value-added tax was an additional blow, although it was reduced to 10% in the middle of the year. Russian publishing appears to be healthy in spite of those problems, although statistics from the Russian Book Chamber (Rossiiskaia knizhnaia palata) are notoriously unreliable. Statistics on books carried by Russian Press Service give an approximate picture of scholarly book publishing.  相似文献

Sex workers in India constitute a marginalized population. They are considered at high risk of HIV/AIDS and are stigmatized for “selling sex” in a culture that generally censures sex outside marriage. HIV/AIDS initiatives targeted at this population have mostly adhered to promoting condom use, increasing awareness, and encouraging blood tests to screen for HIV/AIDS. Missing from this discourse are voices of sex workers and their autonomous consciousness. Based on an analysis of interview data from an eight-week field project, this paper seeks to centralize sex worker subaltern rationality in a call to reframe expert-led HIV/AIDS communication efforts that cater to sex worker communities.  相似文献

The present study uses a rhetorical/normative perspective to examine families' communication and coping in response to a parent's diagnosis of, and eventual death from, lung cancer. Through in-depth, semistructured interviews with 35 adult children, we identified two broad areas of communicative avoidance (avoiding information and avoiding emotion) and three general ways of managing avoidance and openness (denial, segmentation, and being open while avoiding). The interviews suggested that denial was a particularly dissatisfying means of managing competing goals, whereas being open while avoiding appeared to be functional for family members. The discussion focuses on our understanding of reasons why people avoid in this context, implications for rhetorical/normative approaches and theories of information management, and practical implications of the current findings.  相似文献

The aim of this paper is to study the development and evolution of secondary school libraries into Media Resource Libraries (MRLs) in Singapore after the Second World War and the rationale to have mandatory school library standards. It is an historical survey analysing published data about the linkages of libraries and librarianship, school library standards, education and school reforms in Singapore. It analyses historical and current documents on the roles played by stakeholders like the Library Association of Singapore (LAS) and the Ministry of Education (MOE) in the introduction and development of school library standards. The need for school libraries standards was first discussed when the Malayan Library Group (MLG) organised the first course on librarianship for school teachers in 1955, but, with no follow through. The need for school libraries standards was also mentioned by the LAS in 1962 in a memorandum to the Commission of Enquiry into Education to train teacher librarians and adopt school library standards. However, this was left out in the final report of the Commission published in 1964. The need for school library standards was discussed in a school library seminar for 150 teacher librarians in 1970. The first Recommended Minimum Standards for Secondary School Libraries was published two years later by the Standing Committee on Libraries set up by the MOE, but it was not mandatory for schools to adopt the standards. In 1997 the MOE launched its “Thinking School Learning Nation” vision to teach thinking skills. Students were expected to do multidisciplinary project work and be independent users of information. The MOE began to convert school libraries into Media Resource Libraries (MRLs) with print and non-print materials. However, a survey conducted in 2001 on the roles and competencies of 112 Library Coordinators (LCs) or teacher librarians revealed that they lack the skills and knowledge to manage MRLs effectively. This is because subsequent school library standards published in 1983 and 2002 did not require trained and full-time teacher librarians to manage the MRLs. Furthermore, it is essential for the standards to be periodically updated with regards to professional staff, collection development, facilities, Information and Communications Technology (ICT) infrastructure and school library programs. Otherwise, MRLs risk being “hollow shells still considered on the periphery of core educational requirements, and are run by teachers not professionally prepared to do the work” (Hart, 2001, p. 25). The national standards published in the United States from 1918 to 2008 are well researched and provide substantive guidelines to develop school libraries. Therefore, it is essential for the MOE to formulate MRL standards by doing comparative studies of school library standards in other countries. These standards have to be mandatory and fully adopted by the schools. It provides opportunities for stakeholders like the LAS, National Library Board (NLB), the National Institute of Education (NIE), and the Singapore Teachers’ Union, to collaborate in the formulation of these standards and take collective ownership to implement them.  相似文献

The library profession needs to improve its ability to critically examine advocacy research and statistical studies. More proactive evaluations of claims made in advocacy campaigns and research reports will help improve the overall quality of library advocacy and fortify the institutional standing of libraries. As an illustration, this paper provides an in‐depth assessment of a measurement scheme used in the OCLC study From Awareness to Funding (2008).  相似文献

ABSTRACT

At Oregon State University, writing instructors and librarians collaboratively teach research writing and information literacy in first year composition courses. A four-week unit focuses on the connections between critical thinking, writing and learning, and information literacy. This article describes the process of developing, implementing, and refining this collaborative curriculum. By using assignments and texts that model a recursive critical research and writing process for students, librarians and writing instructors help students think more deeply and critically about their topics.  相似文献
