3. Univ Talca, Dpto Econ Agr, Talca, ChileThe growing demand for the consumption of organic foods at worldwide level presents sales increasing by over five thousand million dollars per year. Demands extended to development countries like it is the Chilean case, which exports 90% of its production getting an internal market with low development for this type of products. The research tries to identify the constructs to characterize the potential consumers of organic foods. A survey was applied to 422 consumers to carry out the research in the Maule Region, central Chile (C. I. = 95.5%; e = 3.0%). The Information was analyzed through multivariante technic denominated factor analysis of principal components. The main results of the research reveal the existence of four dimensions or constructs, corresponding to: (1) benefits of the organic agriculture; (2) healthy feeding; (3) lifestyles; (4) attribute of organic foods. These four factors influence in the attitude and purchase intention for the consumers toward the organic foods. In addition being key elements when formulating market strategies for organic products
Criterios de clasificación y re-definición de un perfil comercial de la Agricultura Familiar Campesina, Región del Maule, Chile
Full text linkJara-Rojas, R (reprint author), Univ Talca, Fac Ciencias Agr, Dpto Econ Agr, 2 Norte 685 Talca,Casilla 747, Talca, Chile.In Chile, small-scale farmers are classified according to old approaches from 1993 that do not include changes occurred in the last two decades. Maule is the region with most rural population in Chile which represents a significant stratum for development, innovation and competitiveness. This study explores a new approach of small-scale farmers -associated with Family Farm Agriculture (AFC) - classification in Chile and it describes a commercial profile or AFC-1 for famers of the Maule Region. A Cluster analysis to determine AFC-1 farmers is used. The analysis includes four association variables: Total Assets, Farm Income, Production Costs and Management Indicators. The results suggest that 16.4% of the farmers have a commercial profile and they could stay out support provided by the National Institute for Agricultural Development (INDAP). This group of farmers would not belong to AFC in short terms. This fact could bring restriction to AFC-1 farmers such as lack of credit access, less investment incentives and technical assistance. Thus, it would expect low process of technology adoption and welfare improvement. New agrarian policies must be warranted to support this important group of famers with a commercial profile
An analysis of the joint adoption of water conservation and soil conservation in Central Chile

[ 2 ] Univ Connecticut, Dept Agr & Resource Econ, Storrs, CT 06269 USAStudies reveal that 80% of the world's agricultural land is showing signs of moderate levels of soil erosion. On the other hand, it is a fact that water is becoming a more scarce resource jeopardizing food security. Thus, conserving both water and soil are two of the most pressing issues in international agriculture and food production. This article examines the impact of natural, social, human, and financial capital variables on the adoption of water conservation and soil conservation (WC&SC) as a joint decision, using a bivariate model. Socioeconomic and production information was collected by surveying a random sample of 319 small-scale irrigated farms in central Chile in 2005. The results suggest that the adoption of WC&SC is a joint and complementary decision. The results also indicate that farm size, production system, access to credit, and government incentives are important variables associated with the adoption of conservation measures. From a policy stand point, the institutions in charge of providing incentives and administering instruments intended to promote conservation should take into account the complementarity of the adoption decisions. Program designs should incorporate incentives that jointly promote the adoption of WC&SC in order to enhance effectiveness. (C) 2012 Elsevier Ltd. All rights reserve
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
