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
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
Assessment of the Lands Tribunal in Resolving State Land Conflicts in Zambia
Get PDFThe objectives of this article are to: 1) investigate the different types of state land conflicts occurring in Zambia; and 2) establish whether or not the Lands Tribunal is efficient and effective in resolving state land conflicts. Methodologically, qualitative methods (interviews and questionnaires) supported by documents were used. These research methods were used to conclude that state land conflicts such as invasion of idle or undeveloped private or public land, illegal allocation of land by some politicians and some government officials, violent land acquisition by political cadres, boundary conflicts, multiple allocations of land, eviction by private landlords, and eviction by government agency are occurring with greater frequency in Zambia. However, the Lands Tribunal is unable to adequately resolve these land conflicts due to its centralised nature, limited capacity and lack of public awareness. It is recommend that, guided by research, the Zambian government should consider strengthening the Lands Tribunal by decentralising it to district level, and ensure ongoing capacity building (i.e. adequate funding, ongoing training programme, sufficient transport, and adequate human resource) and awareness.

MITIGATING LAND CORRUPTION THROUGH COMPUTERISATION OF STATUTORY LAND GOVERNANCE ACTIVITIES: EVIDENCE FROM DRC, TANZANIA AND ZAMBIA
Get PDFThis study was on mitigating land corruption through computerisation of land governance activities that include land use planning, cadastral surveying, servicing of land, land allocation, land registration and titling and land development. Using evidence from Lubumbashi (Democratic Republic of the Congo), Dar es Salaam (Tanzania) and Kitwe (Zambia), the study used both primary and secondary data to conclude that despite computerisation of land governance activities in Tanzania and Zambia, corruption still persists. On the other hand, land governance activities in Lubumbashi (Democratic Republic of the Congo) were still paper based and this made the activities highly susceptible to corruption. Causes of corruption identified were low salaries for employees in public land institutions, delay in payment of salaries, lack of monitoring in the services provided, cumbersome procedures, and lack of transparency. In view of these, it is recommended that the respective governments should work on reducing corruption through increasing salaries for employees in land institutions, pay salaries on time, effective monitoring in the services provided, streamlining procedures and ensure transparency
Die Rolle von Land-governance bei der verbesserten Sicherung von Grundbesitz in Sambia: Auf dem Weg zu einem strategischen Rahmen für die Verhinderung von Landkonflikten
Get PDFZambia is one of the countries in Africa with a high frequency of land conflicts. The conflicts over land lead to tenure insecurity. In response to the increasing number of land conflicts, the Zambian Government has undertaken measures to address land conflicts, but the measures are mainly curative in nature. But a conflict sensitive land governance framework should address both curative and preventive measures.Sambia gehört zu den Ländern in Afrika mit den meisten Landkonflikten. Diese haben zur Folge, dass es Unsicherheiten darüber gibt, wem die Grundstücke gehören. Um das Problem der wachsenden Zahl dieser Konflikte zu lösen, hat die sambische Regierung eine Reihe von Maßnahmen eingeleitet, die zur Lösung beitragen sollen; jedoch sind diese Maßnahmen meistens nur kurativ. Ein Rahmen von wirklich konfliktlösenden Maßnahmen zur Regelung solcher Grundstücksprobleme müsste beides, kurative und vorsorgende, Eingriffe enthalten
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
