Analysis of Household Level Determinants of Food Security in Jimma Zone, Ethiopia
Full text linkThe study look for examining food security status of rural households in Gomma District in south western Ethiopia. Household caloric acquisition method was used to measure the status of food security. Household survey was conducted on 190 households and based on these households binary logistic regression model was estimated. Variables related like age, income from off farm/non-farm activities, size of cultivated land, livestock and oxen ownership were found to have positive impact for the attainment of household food security. Likewise use of chemical fertilizer and soil and water conservation practice were found to have positively affecting household food security in the study area. The finding indicated that development interventions that aimed to encourage older households to share their experience to younger households, diversify income of the households, improving productivity of land and livestock, improving the supply and access of chemical fertilizer, incentives to use soil and water conservation activities are found to improve the food security status of the households , thus concerned bodies need to do access and that aimed to diversify income of the households, improving the supply of chemical fertilizer , improving the productivity of land and livestock will have paramount importance for the attainment of household food security. Generally, this study has implication that attaining household food security in southwestern Ethiopia needs mixed adoption of policies and strategies.

Assesment of Food Security Status of Selected Livelihood Groups in Jimma Town
No full textThe main objective of the study was to assess the status of household food security of
three livelihood groups in Jimma town since livelihood approach is a practical tool for the
analysis of household food security. The research was comparative survey among
households of three selected livelihood groups namely urban agriculture, small trade and
manufacture. Multi stage mixed sampling procedure was used to draw 98 sample from
selected livelihood groups. Both primary and secondary data were collected for this study.
Primary data were collected through formal survey using semi structured interview
schedule, key informant interview and focus group discussion; whereas, secondary data
were collected from micro and small scale bureau of Jimma town, central statistical
agency bureau and internet. The collected data were analayzed using SPSS version 22.0.
Household food security was measured by employing household caloric acquisition based
on minimum requirement. Accordingly, 29.6% and 70.4% of the respondents were found to
be food insecure and secure, respectively.To adress the objective of the study, binary logit
and FGT model were used. Among 11 variables included in to the model, household size,
access to technology, dependency ratio and income of the household were found to be
significant. Food insecure households cope food shortage through reducing quantity and
frequency of meal, shifting to cheaper food items, borrowing from relatives, selling
existing assets and searching additional daily work. Thus, designing and implementing
different interventions with respect to significant variables is very important to alleviate
the problem of food insecurity in each sectors in Jimma town
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
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
Factors determining the food insecurity status of rural household of rural household Manna Woreda of Jimma zone, Ethiopia
No full textThis study was conducted in Manna woreda which is found in Jimma zone at a distance of 368 km south west of Addis Ababa and 24 km west of Jimma town. The objective of the study was to identify the determinants of household food insecurity in rural households. Even though majority of the sample households were found to be food secured, the number of food insecure households was not small. To know the food security status of the households, the data collected from sampled respondents regarding food preparation for seven day recall and daily consumption record were converted to kilocalorie using the Food Composition table manual. After that the major demographic, socioeconomic and institutional variables were assessed to look into their relative importance in determining the state of food security at household level. Accordingly Large family size and Asset possession, sex of the household head , number of oxen owned, Access to improved seed and chemical fertilizer are found to be the determinants of food insecurity in the area, Existence of major animals diseases and pest that affect crop production were found to significantly determine individuals food insecurity status. In addition, Some of the coping strategies that are used by food insecure household were assessed. Their local coping strategies at initial and severe stage includes: sale of livestock and productive assets as well as marketing of wood/charcoal which can in turn aggravate the problem of food insecurity
