Comportamiento y formas de organización de la maquila agrícola en una región de agricultura altamente tecnificada
No full textLa contratación en el valle de Culiacán, Sinaloa, de los servicios de mecanización, mejor conocida
con el nombre de maquila agrícola, es una actividad utilizada por un sector significativo de
productores agrícolas, tanto los de tipo empresarial como los de carácter campesino. Así, si bien
los grandes productores generalmente poseen maquinaria, algunos utilizan la maquila
regularmente, ampliándose el número de contratantes de los servicios de maquila agrícola entre
los medianos y, aún más, entre los pequeños productores, aunque sea en actividades mínimas y
puntuales dentro del ciclo agrícola. La maquila agrícola se presenta como un mecanismo de
integración de los productores al mercado, el cual les obliga a operar su escala productiva. Para
responder a esta condicionante estructural, desarrollan diversas estrategias productivas, entre las
que destacan aquellas que les puedan garantizar, por lo menos de inicio, incrementar, o por lo
menos sostener, la rentabilidad productiva. El análisis de la maquila agrícola parte de la realidad
concreta en que está inmersa, del tipo de productores que atiende, por ende, de los servicios que
oferta, de las características territoriales y locales que le sirven de marco de ubicación y de la
estructura productiva y agraria particular que la delimitan, al ser los factores determinantes en su
operatividad.
El objetivo de la investigación fue estudiar el comportamiento y las formas de organización de la
maquila agrícola en una región de agricultura altamente tecnificada, donde se definen regiones y
territorios de acción, se desarrollan relaciones de poder y dominio, se conforma una cultura
tecnológica y se organizan los circuitos de comercialización de cultivos agrícolas, de servicios
rurales, de fuerza de trabajo y de tierras, estableciendo sus enlaces y correlaciones. El estudio se
realizó partiendo de un enfoque analítico, de tipo causal o correlacional. Se utilizó un enfoque
metodológico mixto. El diseño de investigación fue de carácter longitudinal. El trabajo se dividió
en dos fases: a). de gabinete y b) de campo: recolección de datos en campo, aplicación de
encuesta, muestreo de juicio no probabilístico; y entrevistas estructuradas y semiestructuradas.
Las unidades de análisis fueron el municipio de Culiacán, Sinaloa y los maquileros agrícolas.________Recruiting in the valley of Culiacan, Sinaloa, mechanization services, better known as agricultural
maquila is an activity used by a significant segment of agricultural producers, both business-like
character as the peasant. Thus, while large producers generally have equipment, some use the
maquila regularly, expanding the number of contracting agricultural maquila services among
middle-and even more, among smallholders, albeit minimal and specific activities within the
agricultural cycle. The agricultural maquila is presented as a mechanism of integration of
producers into the market, which requires them to operate their production scale. To answer this
structural condition, develop various strategies for production, among which are those that
guarantee them at least start, increase, or at least sustain the profitability of production. The
analysis of agricultural maquila part of the factual situation in which it is, the type of producers it
serves, thus offering the services of regional and local characteristics that serve as a framework of
location and the production structure and particular land that surround it, being the determining
factors in their operation.
The research objective was to study the behavior and organizational forms of agricultural maquila
in a region of high-tech agriculture, outlining action regions and territories, relations of power and
domination, is content and technological culture organized marketing channels for agricultural
crops, rural services, labor force and land, establishing their links and correlations. The study was
conducted based on an analytical approach of causal or correlational. We used a mixed
methodological approach. The research design was longitudinal in nature. The work was divided
into two phases: a). Cabinet b) field: field data collection, survey implementation, non-probability
sampling trial, and structured and semistructured interviews. The units of analysis were the
municipality of Culiacán, Sinaloa and agricultural miller.Tesis ( Doctorado en Ciencias, especialista en Desarrollo Rural).-Colegio de Postgraduados, 2009.CONACY
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
