Estimación de los valores económicos para la producción y caracteres funcionales en el ganado lechero de la asociación Aspranues de la parroquia de Belisario Quevedo para el establecimiento de los objetivos de mejoramiento genético.
Get PDFThe lack of register in the farms, leads to a lack of knowledge of the production cost, and as they do not have production register, it is not possible to establish what our genetic improvement objectives are. By analyzing the production data, it is possible to make decisions that allow to increase the efficiency and profitability of dairy farms. Also, the best cows can be selected based on the established objectives with the ability to transmit those characters to the next generation. Therefore, in the present research project, the dairy production of the Nueva Esperanza Food Production Association (ASPRANUES), located in the Manzanapamba neighborhood, Belisario Quevedo parish, of Latacunga canton was economically analyzed. Which constitutes an associative enterprise made up of 12 women, who have milk production cows and give added value to their primary production by making cheese in an artisanal way, after a process of education and training with the support of different public and private institutions.La falta de registros en las haciendas, conllevan a un desconocimiento del costo de producción, y al no contar con registros de producción no podemos fijar cuáles son nuestros objetivos de mejoramiento genético. Al analizar los datos de producción, se puede tomar decisiones que le permitan aumentar la eficiencia y la rentabilidad de las explotaciones lecheras. De igual forma, se puede seleccionar las mejores vacas en base a los objetivos establecidos con la capacidad de transmitir esos caracteres a la siguiente generación. Por lo tanto, en la presente investigación se analizó económicamente la producción láctea de la Asociación de Producción Alimenticia Nueva Esperanza (ASPRANUES), ubicada en el barrio Manzanapamba, parroquia Belisario Quevedo, del cantón de Latacunga. La cual constituye un emprendimiento asociativo conformado por 12 mujeres, quienes tienen vacas de producción de leche y dan valor agregado a su producción primaria mediante la elaboración de queso de manera artesanal, tras un proceso de formación y capacitación con el apoyo de diferentes instituciones públicas y privada
Derivación de valores económicos de la producción de leche de bovinos en la parroquia Guaytacama utilizando funciones de beneficio.
Get PDFThe genetic evaluation of dairy cattle is the fundamental pillar for a genetic improvement program, considering genealogical and phenotypic information, as well as helping to know dairy farm situation. However, in Guaytacama, small producers carry out a technician not exploitation and their decisions are based on traditional knowledge, consequently, there is a reduced profitability on given productions, mainly due to selection problems of reproducers without the genotype-environment interaction. Therefore, an evaluation of economic values on Guaytacama is carried out to small milk producers, obtaining 31 people that are linked to genetic improvement project with 107 cattle, of which 27 are milk producing cows. The animals are managed at semi-stabled herd, in a space not exceeding one hectare, with a stocking rate of
3.2 UBA. Feeding is deficient due to the size of owners' land; they can not keep this number of animals this space and they also use vacant land and buy feed, increasing the production cost per liter of milk. There is no profit value for milk production if labor hours are taken into account, since the cost of producing a liter of milk is 0.42. If working hours are not considered, the value of 0.13 per liter of produced milk. Density is at the average value of 1.027 g/ml, a value below the normal average of 1.029 g/ml. Daily weight gain is at a value of 570 g/day, lower than normal value of
600 to 700 g/day. The selection criteria that should be applied are gain weight, milk density, daily milk production, which is in an average range of 8Kg/cow/day.La evaluación genética de bovinos productores de leche es el pilar fundamental para un programa de mejoramiento genético considerando la información genealógica y fenotípica, además de que ayuda a conocer la situación en la que se encuentra la explotación lechera. Sin embargo en Guaytacama los pequeños productores realizan una explotación sin tecnificar y sus decisiones se basan en conocimientos tradicionales, en consecuencia se denota reducida rentabilidad en las producciones dadas, principalmente por problemas de selección de reproductores sin considerar la interacción genotipo ambiente, por lo tanto se realiza una evaluación de valores económicos en Guaytacama a pequeños productores de leche, obteniendo
31 personas que se vinculan al proyecto de mejoramiento genético con 107 bovinos, de los cuales 27 son vacas productoras de leche. Los animales son manejados de una manera semi estabulada al sogueo, en un espacio no superior a una hectárea, con una carga animal de 3,2
UBA. La alimentación es deficiente por el tamaño de tierras que tienen los propietarios, no se pueden mantener a esta cantidad de animales en ese espacio además de que utilizan terrenos baldíos y compran comida aumentando el costo de producción por litro de leche. No existe un valor de beneficio por la producción de leche si se considera las horas de trabajo, ya que el gasto por producir un litro de leche es de 0.62. Si no se considera las horas de trabajo se obtiene valores de 0,13 por litro de leche producido. La densidad se encuentra por el valor promedio de 1,027 g/ml un valor bajo al promedio normal de 1,029 g/ml. La ganancia diaria de peso se encuentra en un valor de 570 gr/día un valor inferior al considerado como normal de 600 a 700 gr/día. Los criterios de selección que deberían aplicarse son: ganancia de peso, densidad de la leche, producción diaria de leche, que se encuentra en un rango promedio de 8Kg/vaca/día
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
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
