The Economics of Non-Timber Forest Products in Cameroon: The Case of ERU (Gnetum)
Get PDFThis paper seeks to understand the economics of non-timber forest products, especially Eru (Gnetum) in the Southwest Region of Cameroon. It uses descriptive and econometric approaches on a stratified random sample of 400 participants, complemented with information from literature to capture the objectives of investigation. Results of the study indicate that the demand for Eru is own-price, cross-price inelastic, income elastic; positively related to quality and highly consumed by male than female breadwinner of households in the study area. The study further recognizes the impediments such as shortage of infrastructures, lack of proper sanitation, frequent coercion on participants while conveying the product to the market, absence of government support to participants; and potentials for international trade gains for Cameroon. Thus, it is recommended that Cameroon formalize the Eru-trade with importing countries that export other goods whose demand in Cameroon is elastic to improve its balance of payments position and increase its volume of exports and imports

No full text Many Cameroonian households are confronted with short supply of drinking water as the state-owned water corporation failed to meet the efficient water delivery objectives. As a result, the privatisation drive took place with of course some consequent impacts. The current study is an attempt to quantify these impacts. The major impacts are in terms of decreased access to water to households by 8 percent and exposure of more than 70 percent of households to irregular water supply for more than half a month. However, some 92 percent of the households rate the quality of water obtained from the private water company good. Also, 56 percent of the households prefer the service delivery by the private company over that of the state-operated water supply. Besides, both the minimum and maximum amount households wish to pay per cubic meter of water for continued private water provision exceeds the current rate by 5.59 and 225.99 percent, respectively.

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
