Diversity, Challenges and Potentials of Enset (Ensete ventricosum) Production: In Case of Offa Woreda, Wolaita Zone, Southern Ethiopia
Get PDFThe main objectives of the study were to investigate the existing diversity of enset clones selected for different purposes; its challenges and contribution of enset production for sustainable livelihood security of the rural community in the study area. The result revealed that farmers were rich in diversity in that they grow various types of clones in the same farm for their intended purposes. Among diverse enset clones grown in the area, the top 5 clones which are selected for kocho, workey and bulla include halla, falakiya, tuzuma,nakaka and gena. Similarly, clones selected for amicho (corm) include arkiya, nakaka, gena, chichiya and peluwa; and those selected for fiber include halla, falakiya, tuzuma, maziya, and argama. Generally, clones halla, nakaka, tuzuma, maziya and kekeruwa are some of the clones of multipurpose. Enset plays a vital role in contributing food and livelihood security of majority of the society in the study area. In line with this, about 63% of the sample farmers reported that the yield of enset is higher than other major crops including root and tuber crops produced in the area. Farmers identified the major challenges and about 55% of the sample farmers indicated that land shortage was the 1st serious problem in the area followed by disease and recurrent drought which account for about 16% and 14.7%, respectively. Therefore, critical reduction of enset production and its diversity calls for future collective action to generate new technology in every aspect including production, processing and extension services to utilize the crop potential. Furthermore, clone of multipurpose such as halla, nakaka and tuzuma need to be promoted further to utilize crop potential and to contribute for sustainable livelihood security of rural people.

Determinants of Women Participation in Micro and Small Enterprises in Hadiya Zone, Ethiopia
Get PDFThe study was undertaken with the objective of assessing determinants of women participation choice and intensity of participation in Micro and Small Enterprises in Hadiya zone, Ethiopia. Within the zone three town administrative were selected based the largest number of economic activities. The investigation was grounded on cross-sectional review information from 385 women Micro and Small Enterprise's undertakings participant and non-participant that were assigned using semi-structured interview schedule, key informants interview, focus group discussion, and personal observation. Secondary data was acquired from empirical reports, government policy documents, national statistical reports, journal articles and reports of different organizations. Heckman's two-stage selection model was applied to recognize factors influencing women's participation decision and intensity of participation in MSEs. The first level of probit model estimation results reveal that educational status, business experience, access to credit, access to training, achievement motivation, receiving remittance, information seeking behaviour and initial capital were emphatically and fundamentally impact the likelihood of women participation decision in MSE while age was negatively related and does significantly determine the participation choice of the women. The after effects of the second stage Heckman model demonstrated that the intensity of participation in Micro and Small Enterprises was significantly and positively influenced by educational status, access to market, access to transportation, and achievement motivation. Hence, this study recommends that government and concerned bodies are anticipated to enhance the educational level, skill, and knowledge development training, provide aids and subsidized to income, credit facilities, and the remittance-receiving channels. It is also suggested that women should formulate their own goals and they should participate in business by their own choice nevertheless of other alternatives accomplish well and actions need to be accepted to offer incentives for women who have faced a lack of available initial capital in the study area

Factors Affecting the Level of Rural Households Livelihood Diversification in Gamo Zone, Southern Ethiopia
No full textLivelihood diversification is enchanting a significant effect in generating household’s income. The livelihood diversification includes:on-farm, non-farm and off-farm strategies which are undertaken to get extra income and moderate hazard and insecurity. The purpose of this study was to examine the factors affecting the level of rural household livelihood diversification in Gamo Zone, Southern Ethiopia. The study was conducted by using a cross-sectional research design. It is a quantitative dominant concurrent mixed research methodology where the qualitative research is complemented with interpretations and triangulation. By applying multi-stage random sampling technique, a sample size of 400 household heads from 6 sample villages was selected and data were collected using interview schedule and via key informant interviews and focus group discussions. Descriptive statistics were analyzed and presented by using tables, graphs and figures while chi-square-test and F-test were employed to make statistical inferences. Tobit model was employed to identify the intensity of factors affecting of rural household’s livelihood diversification. Out of the 14 hypothesized explanatory variables, 6 variables namely age, education, access to extension, media access, distance to urban centers and training were found to have significant effect in rural household livelihood diversification decision. Therefore, the findings of this imply that rural households’ development policies should consider these factors in designing rural household livelihood diversification strategy

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
