Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
The Impact of Free Trade Agreements (FTAs) on Business in the Republic of Korea
No full textThe Republic of Korea (hereafter Korea) continues to promote an open-trade system via the conclusion of free trade agreements (FTAs), arguing that Korean enterprises will obtain considerable business opportunities under the FTAs the government has implemented. However, the FTAs that are currently being implemented in Korea are said to be beneficial only to some enterprises. This study presents new evidence from a survey conducted from July–August 2008 on 120 Korean firms. The paper explores critical questions regarding the utilization of FTAs, their perceived costs and benefits, perceptions of multiple rules of origin (ROOs), and policy and institutional support mechanisms for FTAs. One of the key findings is that most of the currently implemented FTAs in Korea were concluded with small- and medium-sized developing countries. Moreover, within these FTAs, the range of preferential tariffs is not very broad in scope; as such, only one out of five enterprises was found to be utilizing them. However, since the conclusion of FTAs with the United States and the European Union, Korean businesses have become very interested in utilizing those respective FTAs. The government should make efforts for early implementation of these FTAs. In the FTAs concluded by Korea, ROOs are strict and complicated. In future FTAs, a more neutral and lenient form of ROOs should be adopted.free trade agreement korea; korea fta impact; korea fta trade business
Decomposition of modal acoustic power due to cascade–turbulence interaction
No full textThis paper investigates the modal acoustic power (MAP) generated by a cascade of flat-plate airfoils interacting with homogeneous, isotropic turbulence. The basic formulation for the upstream and downstream acoustic power based on the analytical theory of Smith [Discrete frequency sound generation in axial flow turbomachines, Reports and Memoranda no. 3709, Aeronautical Research Council, 1972] and its generalization to broadband noise due to Cheong et al. [High frequency formulation for the acoustic power spectrum due to cascade–turbulence interaction. Journal of the Acoustical Society of America 119 (2006) 108–122]. The MAP has been expressed as the sum of cut-on acoustic modes, whose modal power is the product of three terms: a term that specifies the wavenumber distribution of mean square velocity, a sound power factor that specifies the efficiency of radiation, and an acoustic blade response function. The effect of these terms on the MAP is discussed in detail in this paper. The acoustic blade response functions are found to determine the modal lines of minimum sound power in mode-frequency maps of the MAP. The upstream sound power factor is less than the downstream power factor, which is generally large, especially away from the cut-off frequency. Both power factors are small for modes close to cut-off. Modes close to cut-off, therefore, do not contribute significantly to the radiated acoustic power in the downstream direction, even though the modal pressure amplitude for these modes is high since they are excited close to resonance. For an isotropic turbulent gust, the mean square velocity wave number spectrum reduces only the magnitude of the MAP without altering the distribution of power in the frequency-mode map<br/
Author, publisher and bookseller : a tripartite synergy in Nigerian book industry
No full textThis work is about the roles of Author, Publisher and Bookseller in Book development in
Nigeria. The paper started by delving into the history of Book Publishing in Nigeria after
which it proceeded by defining who an author, a publisher, and a bookseller is and
expatiated on the indispensable roles of these key actors in Nigerian Book Industry and in
the emerging Information Society. Furthermore, the various constraints to book
development were identified while the paper advised on how the Book Industry can be
further promoted in Nigeria. However, the paper concluded and made recommendations
on how the Book sector can help in enhancing scholarship in the country

Evaluating E-Government Implementation in Public Service Delivery
No full textThe purpose of this study is to assess e-government implementation in public service delivery and to examine
stakeholders/customers trust on e-government service. This study applied the Technology Acceptance Model (TAM: Davis, Bagozzi, & Warshaw 1989) to investigate the factors affecting e-government implementation. The results indicate that factors including ICT infrastructure, human capital, online service, and risks and barriers significantly affect the ease of use and usefulness of e-government services. This study also examined the intention to improve egovernment service by selected organizations and service provider perception of stakeholder/customer trust in the egovernment service provided. This study also finds that the intention to improve e-government service is better in all selected organizations, whereas perceived stakeholders’/customers’ trust level in e-government service is similar across all selected organizations which is insignificant.1
