Are Tree Tenure and Land Tenure Issues the Same? A Case Study of Rights to Trees among the Tsamako of Southwest Ethiopia
No full textThere has been confusion as to whether land tenure and tree tenure issues should be looked at as two distinct entities or not. In this article I describe the various means of establishing rights of access to trees and other savannah woodland resources and how such rights are socially sanctioned as distinct from the overlapping land tenure system prevailing in the country today. The discussion focuses on issues raised by differential rights of access by multiple users for multiple purposes, and attempts to show the various ways of establishing tree primary user rights as distinct from those held in jointly managed woodlands. This happens, interestingly, contrary to the received wisdom that pastoralist societies ‘lack’ basic social norms let alone to have a set of rules designed to regulate the use and protection of trees. Finally, through an examination of the ways in which rules which apply to trees are enforced, both generally and in particular cases, I argue that it is the relatively low demographic density, a relatively homogeneous community and the resultant quick acquisition and dissemination of information and an inclusive decision-making system at the grass-root level which have made rule enforcement relatively easy and cost-effective. These resulted in a system which encourages tree protection and long-term oriented multiple uses. This article is based on data drawn from eighteen months of ethnographic field research which provided the author with the opportunity to employ a range of data collection techniques including key informant interviews, focus group discussions and participant observation.  
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
Predictors of Irregular International Migration among Youth in Jimma Zone, South West Ethiopia
No full textThis article deals with irregular international migration among the youth in south-west Ethiopia, which is one of the major issues that grabbed the attention of the international community in recent years. The article draws on a study which aimed at determining major predictors of irregular migration intention among youth in Jimma Zone, Southwest Ethiopia. Irregular migration and human trafficking are serious challenges that people face in Ethiopia in general and in Jimma Zone in particular. Concurrent cross-sectional mixed method study design was deployed, and a total of 347 respondents participated in a quantitative survey and 33 and 6 took part in five Focus Group Discussions and in-depth interviews respectively. The study was conducted in three selected woredas/districts of Jimma Zone between March and April 2018. Variables such as age, political unrest, unreliable information from social media, social networks, the desire for life enhancement, and readiness for taking risk are found to be good predictors or reasons of irregular migration. Age has strong negative correlation (r=-0.73) with irregular migration intention. Personal readiness has very strong (r=0.96) and positive correlation with irregular migration intention. In conclusion, youth in particular and community in general in Jimma Zone favor irregular migration to home situation and prefer to try out other life as livelihood strategy
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
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
