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
Trends in immunization completion and disparities in the context of health reforms: the case study of Tanzania.

Of global concern is the decline in under five children mortality which has reversed in some countries in sub Saharan Africa (SSA) since the early 1990 s which could be due to disparities in access to preventive services including immunization. This paper is aimed at determining the trend in disparities in completion of immunization using Tanzania Demographic and Health Surveys (DHS). DHS studies randomly selected representative households from all regions in Tanzania since 1980 s, is repeated every five years in the same enumeration areas. The last three data sets (1990, 1996 and 2004) were downloaded and analyzed using STATA 9.0. The analysis included all children of between 12-23 months who would have completed all vaccinations required at 12 months. Across the time periods 1990, 1996 to 2004/05 the percentage of children completing vaccination was similar (71.0% in 1990, 72.7% in 1996 and 72.3% in 2005). There was no disparity in completion of immunization with wealth strata in 1990 and 1996 (p > 0.05) but not 2004. In 2004/05 there was marked disparity as most poor experienced significant decline in immunization completion while the least poor had significant increase (p < 0.001). All three periods children from households whose head had low education were less likely to complete immunization (p < 0.01). Equity that existed in 1990 and more pronounced in 1996 regressed to inequity in 2005, thus though at national level immunization coverage did not change, but at sub-group there was significant disparity associated with the changing contexts and reforms. To address sub-group disparities in immunization it is recommended to adopt strategies focused at governance and health system to reach all population groups and most poor.\u
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
Understanding Stakeholders’ Roles in Health Sector Reform Process in Tanzania: The Case of Decentralizing the Immunization Program.
Get PDFThe current need and enthusiasm for health reforms open an important arena for deeper analysis of the policy process with a view to understanding the political determinants of reforms and strengthening implementation. The studies described in this thesis analyse positions of different actors in the reform process, their actions in support or opposition of the process, and their impact on the health sector reform process. Globally and especially in developing countries health sector reforms have been implemented over long periods. Although there have been improvements in health, the remaining burden of disease in many countries is still very high. Reasons for the high burden of disease have been classified into lack of resources and poor organizational and managerial capacity. Good stewardship was needed to facilitate improvement in the performance of health systems. Stakeholders’ alignment and support was one of the most important components of good stewardship. However, stakeholder analysis had not been a common undertaking in developing countries despite the reforms that were being implemented in most of them. It was the aim of this study to answer the question: What has been the role and importance of stakeholders in supporting or opposing the health sector reform process? The study was conducted in Tanzania as one of the poorest countries in Africa, using the decentralization of the Expanded Programme on Immunization (EPI) as a case reference. The study units were the Ministry of Health Headquarters, Medical Stores Department, Expanded Programme on Immunization, national archives, regions and districts. At district level the study units were District Council, Council Health Management Team, EPI managers at regional and district levels, ward and village authorities, health facility, facility providers and households. Qualitative and quantitative methods were used to collect data from January 2000 to June 2002. Relevant data collection instruments were prepared and pre-tested. The qualitative data collection methods included document review, in-depth interviews, key informants interviews and observations. Quantitative methods involved retrieval of secondary data, health facility survey and household surveys. Regular discussions with key informants and data collectors were held to verify the findings. Qualitative data was analysed manually. Quantitative data was captured and analysed using Epi Info version 6.1 and STATA version 6.0. The study involved answering five main questions. The first question was: Do reforms learn from history? Analysis of the waves of health reforms prior to the current reforms from 1926 was done to answer the question. The main stakeholders in the reforms were the political party in power, the government and donors who supported the reforms each time. Each wave of health sector reforms provided information on health provision, financing and resource generation. Due to the political contexts, information on failures of health financing did not provide lessons for succeeding reforms of the health sector. Stakeholders’ political interests opposed lessons that did not match the political ideology at the time i.e. free public services versus privatization and paying for social services. Lessons from previous health reforms were selective, and did not consider health-financing needs among others. The ongoing health reforms needed to use information from all functional aspects of the health system to provide lessons for improving the health system. The second question was: Who were the stakeholders in the current health reforms and what were their interests and reactions? The main stakeholders were donors, and the government. The two had a very high support for the reforms evidenced by their participation in problem identification, justification, reform design, planning and implementation. The health sector reforms thus had high political support at central level. In the implementation process, issues that triggered stakeholders’ reaction included sectoral versus local government decentralization. Another issue was the donor modality in financing the health sector and need for adopting new financial management systems. Among the donors there was hesitancy to join the common financing modalities that included a Sector Wide Approach (SWAp) and Basket Funding. As a result, there was delay in the process in order to reach better consensus. The third question was: What was the impact of stakeholders in the process of reforming a vertical programme like EPI? Health Sector Reforms in EPI included integration of generic functions, for example, vaccine procurement to medical stores department. Qualitative and quantitative data was collected and analysed from the Ministry of Health, EPI management unit. This again revealed that EPI reforms were well supported by the government and donors centrally. EPI managers at both district and regional levels opposed some of the EPI reforms. They argued that coverage was falling due to the reforms. However, there was no concrete evidence relating reforms in the EPI programme and falling coverage. The primary aim of certain actors was to make sure that they continued receiving extra income from EPI functions. One of the effects of stakeholders’ reaction was reversal of reforms (recentralization) and return to the status quo. The fourth question was: What was the immediate reaction of stakeholders to decentralization at district level and how might it have affected performance of EPI functions and the challenges? The immediate reaction of stakeholders was reduced cooperation between the Council Health Management Team (CHMT) and the District Council who were politically supreme in the district. Within the Council Health Management Team there was inadequate communication, which led to poor teamwork. The result of this was reduced supervisory visits to peripheral health facilities. The EPI coverage in the study district was 52.8 per cent, which was well below the previous national average (80 per cent). A logistic regression model for EPI service quality variables on children between 12 months and 23 months who had completed vaccination was applied. Certain EPI quality of service variables predicted significant changes in the odds ratio for completing vaccination. It was then suggested that strategies were needed to improve management skills among the CHMT and District Council members. Also there was a need of hastening the process of increasing remuneration and motivation of peripheral health workers. The fifth and final question was: What was the interest of the stakeholders and prospects of increasing EPI coverage at district level? Decentralization and integration of EPI functions were among the reforms at district level. The analysis revealed that active stakeholders at district level were the Ministry of Health, CHMT, EPI managers at district and regional levels and facility providers. The Ministry of Health opposed integration of EPI at district level by issuing the directive that DCCOs and MCHCOs (EPI manager at district level) should resume their tasks. However, the CHMT had no option but to comply. This action reversed some of the health reforms at district level. Analysis of the importance the community attached to EPI, using willingness to pay for EPI cold chain kerosene, was done. The support was low (48.7 per cent). EPI service quality variables were significantly negatively associated with odds ratio for willingness to pay for EPI input. Simulation with Policy Maker computer software predicted that an increased number of stakeholders through community participation would significantly improve the current low level of EPI coverage. It was then proposed to do a similar analysis in other vertical programmes and implement on a trial basis the results of the simulation. In conclusion, stakeholders were found to be active and influential in the health sectors of developing countries like Tanzania but poorly considered in implementation of reforms. Stakeholders are important since some strongly support while others oppose the reforms. The reaction of stakeholders is evident through deployment or non-deployment of information depending on interest and context. This would result in poor management leading to inefficiency in resource use, which would then be followed by poor quality of services, poor support by communities and consequently poor utilization of health services. It is suggested that stakeholder analysis be conducted in other vertical programmes in the process of integration. Promotion of stakeholder analysis and also Policy Maker as a tool to manage stakeholders will facilitate the management of reforms in the health sector
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
