Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
From sustainability to sustainable development: the role of food banks in food security in Uganda : a case study of the hunger project food bank - Mbale epicenter
Full text linkMaster thesis in development management - University of Agder 2014The purpose of this study is to identify the role the food bank plays for food security, sustainable livelihoods and building resilience to climate change among smallholder farmers in Uganda. The aim is to investigate how the food bank in Uganda operates in relation to food security and smallholder farmers. Much of the studies on food banks reveal that food banks are merely institutions that offer emergency food supplies to the hungry and are not agencies aiming at food security. These studies have, however, been based on the context of developed countries and no study has been conducted to establish the role of food banks in the context of developing countries. This study was based in the eastern region of Uganda, and used a sample of eighty respondents to examine the role of food banks. The study was conducted qualitatively, guided by the sustainable livelihood framework adapted from the Institute of Development Studies (IDS). The results reveal that, much as it is currently hard to measure the socioeconomic impact of the food bank on smallholder farmers in the area of study because of the difficulty in isolating its contribution from that of interrelated programs and activities farmers are involved in; it is evident that the food bank was playing a significant role in improving the smallholder farmers’ food production and incomes. The food bank is actively engaged in training smallholder farmers in modern farming methods, provision of improved seeds and safe storage facilities for farmers produce, as well as helping farmers do diversify their livelihood sources, and providing climate-related information. Prolonged droughts and lack of access to quality and sufficient seeds are among the main sources of food insecurity among smallholder farmers. Distance to the food bank and lack of access to information are some of the factors that affect many farmers abilities to participate in the food bank activities. Community ownership of the food bank is still lacking and provides a long term threat to the sustainability of the project if not well handled. The study recommends: establishment of community-managed food banks at lower levels to ensure community ownership; ensuring equitable distribution of benefits among all target farmers; encouraging seed saving by farmers; initiation of a community supported agriculture program to reduce the problem of lack of farm credit; and investing in rainwater harvesting facilities
The Role of Food Banks in Food Security in Uganda : the Case of the Hunger Project Food Bank, Mbale Epicentre
No full textThis study addresses the role the food bank plays in food security, sustainable livelihoods and building resilience to climate change among smallholder farmers in Uganda, and in particular eastern Uganda. Currently, it is difficult to measure the socioeconomic impact of the food bank on smallholder farmers in eastern Uganda due to the difficulty of isolating its contribution from that of interrelated programmes and farmer activities. It is, however, evident that the food bank plays a significant role in improving the smallholder farmers’ food production and incomes. The food bank is actively engaged in training smallholder farmers in modern farming methods, providing improved seeds and safe storage facilities for farmers’ produce, helping farmers to diversify their livelihood sources and providing climate-related information. Prolonged drought and lack of access to sufficient seeds of good quality are the main sources of food insecurity among smallholder farmers. Distance from the food bank and lack of access to information are among the other factors that affected many farmers’ ability to participate in food bank activities. Community ownership of the food bank is still lacking, and this is a long term threat to the sustainability of the project. There is therefore an urgent need to establish community-managed food banks at lower levels that ensure community ownership; equitably distribute benefits among target farmers; encourage seed-saving among farmers; initiate community-supported agriculture programmes to improve access to farm credit; and invest in rainwater harvesting for irrigation.Contents: 1.

Variations on the Author
Full text link“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
Full text linkWe 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
Full text linkWe 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
