Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Framework for managing risk in privately financed market projects in Nigeria
Get PDFShortage of funds and the need to improve the living standards of the people are among
the reasons advanced for the recent embrace of Public Private Partnership (PPP)
arrangements in developing markets in Nigeria. Construction work generally, and
especially projects procured using PPP arrangement are more risk prone than those
procured using other forms. This is mainly due to the lengthy concession period and the
multi-parties involved in the arrangement. It is therefore, an imperative to properly
manage the multi-faceted risks associated with PPP market projects (MPs) in a
developing economy like Nigeria.
Review of the extant literature show that little has been done on risk management in
PPP projects in Nigeria with no known effort on PPP MPs. This is due largely to the
novelty of the PPP scheme in Nigeria. The main contribution of this research therefore,
is better understanding of the risk management process in privately financed (PF) MPs
in Nigeria. A holistic risk management framework is developed that identifies best
practices in the risk management process with special emphasis on market projects. The
structure specifies what should be done, who should do it and when it should be done
throughout the whole life cycle of any PPP market project. Risks in (PF) MPs and their
impacts were identified and assessed; allocation preferences of practitioners and
mitigation measures to the risks were also assessed within the south-western part of the
country
Data for the study was collected through a mixed methods approach viz: quantitative
and qualitative approaches. Questionnaires were administered to practitioners in the
industry within the south-western zone of the country to gain general idea on risks that
are likely to occur and affect PF MPs within the region. In-depth interviews were also
conducted with stakeholders on three PF MPs in the region. Descriptive and inferential
statistics were employed to analyse data for the study.
The research identified inadequate knowledge of risk management concept in the
Nigerian construction industry; especially in PPP projects, as being responsible for the
poor performance of PPP projects using the Triple Bottom Line (TBL) - i.e. people,
profit, and planet - as yardstick. It is believed that the framework will serve as a useful
tool for rapidly learning about the risks involved in PPP market projects and for
understanding viable options for their effective management

Executive project management structure and the challenges acing its adoption in the Nigerian construction industry
No full textProject management (PM) is a globally recognized discipline and has been widely adopted within the construction industry. Despite advancements in the PM discipline, the ineffective traditional management system, typical of the non-executive PM structure, is still widely used in the Nigerian construction industry. The aim of this paper is thus to explore the challenges facing the adoption of the executive PM structure in Nigeria. The paper first assesses the level of growth of PM in Nigeria using UK best practices as a benchmark and identifies the key PM characteristics in the two countries. Focus group interviews were used to collect the primary data for the study and content analysis was used to present the results in a thematic format. The study revealed the key barriers to the adoption of an executive PM structure in Nigeria as a lack of proper awareness, unfavorable policies, skill shortages, the traditional culture of stakeholders and the absence of a regulatory body. It is recommended that the government, as a major player/client in the Nigerian construction industry, should lead the campaign to change the traditional industry approach to project management. This is necessary if construction stakeholders in Nigeria are to be educated and encouraged towards adopting and putting into practice effective PM
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
