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
The success of a policy model: Irrigation management transfer in Mexico
No full textThis thesis studies the emergence, process and outcomes of the Mexican policy of Irrigation Management Transfer (IMT). Under the influence of neo-liberal government policies, the transfer of government-managed irrigation districts to water users' associations (WUAs) has radically changed irrigation management inMexicoduring the past fifteen years. Internationally,Mexico's IMT programme has been heralded as a success and has drawn widespread attention because of its rapid implementation. Consequently, it has been propagated as a model for other countries seeking to improve the performance of their public irrigation systems and cut burgeoning public expenditures. This study firstly critically examines the emergence of this policy model and its proclaimed success. Secondly, it discusses the impacts this has on everyday irrigation management. On the one hand, the thesis offers a comprehensive analysis of the entire life cycle of the IMT policy. It traces the idea of transfer back to its bureaucratic roots and reviews how the idea gained political commitment as the consequence of a prolonged bureaucratic struggle. This shows that the IMT policy has a fascinating history that it is tied up with the past and the future of the hydraulic bureaucracy (involved with hydraulic resources and water management). The formerly influential and autonomous Ministry of Water Resources lost its autonomy and its control over the irrigation districts inMexicowhen it was merged halfway the 1970s with the agricultural bureaucracy (responsible for the agricultural sector). At the end of the 1980s, the IMT policy played an important role in the reconstitution of the hydraulic bureaucracy in the Comisión Nacional del Agua (CNA: National Water Commission), which regained autonomy and control over the irrigation districts.On the other hand, this book takes a close look at the everyday organisational practices that have emerged in a WUA around the strategic resources of water, maintenance machinery and irrigation fees. It shows how a political group based in a WUA maintains a network of political and institutional relations by controlling this set of resources. The contribution of this thesis as a whole to the study of policy reform and irrigation management is that it consistently analyses them as political practices that are also expressive of the cultural dimension of human action and social ordering

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
Cultural Performance, Resource Flows and Passion in Politics: A Situational Analysis of an Election Rally in Western Mexico
No full textThis article contributes to a growing body of literature that questions state-centred approaches to analysing politics, adopting a more de-centred and cultural perspective. It does so by presenting a situational analysis and detailed ethnography of a local election rally in Western Mexico. The analysis of this event as a cultural performance highlights the dramatic enactment of culturally significant acts as a central part of electoral behaviour and shows how everyday organisational life, resource flows, public ritual and passion play a part in politics. That such acts are not merely symbolic is demonstrated by what occurs behind the scenes of political ritual: a local political group appropriates a Water Users' Association and draws on its staff, facilities, resources and wider power relations for its political campaign. Such practices also indicate the unanticipated outcomes of recent administrative decentralisation reforms. New producer organisations created by these reforms to administer former government tasks more efficiently are appropriated politically, not simply in an instrumental, but also in a culturally specific manner
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
