Asistencia religiosa y Derecho del trabajo: el caso de los Ministros de Culto
Fabiola Vergara Ceballos
Revista Chilena de Derecho y Ciencia Politica , 2013, DOI: 10.7770/rchdycp-v4n1-art409
Abstract: La doctrina laboral, por medio de la determinación y desarrollo de los elementos esenciales del contrato de trabajo, permite esclarecer si en determinados supuestos de hecho se configura o no una relación laboral que deba materializarse en un contrato de trabajo. Esta cuestión cobra vital importancia respecto de servicios en los que se presentan dudas sobre si dan o no lugar a dicho contrato, como en el caso de las labores de los ministros de culto (e.g., pastores, sacerdotes, rabinos, diáconos) y demás personas autorizadas, por sus respectivas iglesias, para otorgar asistencia religiosa de su propia confesión y que, en ocasiones, también desarrollan tareas que pueden catalogarse de profesionales (médicos, profesores, entre otros).
PREVALENCIA DE BRUCELOSIS EN LA LECHE CRUDA DE BOVINOS EXPENDIDA EN EL MUNICIPIO DE POPAYáN CAUCA SEPTIEMBRE - DICIEMBRE 2006. PREVALENCE OF BRUCELLOSIS IN CATTLE RAW MILK SPREAD IN THE CITY OF POPAYAN CAUCA. SEPTEMBER-DECEMBER 2006

Abstract: La Brucelosis bovina es una zoonosis de declaración obligatoria y la de mayor difusión en el mundo según la Organización Mundial de la Salud OMS. Esta enfermedad ocasiona pérdidas importantes en la producción, reproducción del ganado lechero y en humanos afecta la salud, productividad y calidad de vida. El propósito de este trabajo es determinar la prevalencia de Brucelosis en la leche cruda que se expende en el Municipio de Popayán e identificar factores asociados con la presencia de brucelosis en los diferentes hatos proveedores de leche cruda. Se realizó un estudio descriptivo de corte transversal, se evaluaron 247 muestras de leche cruda comercializadas en el Municipio de Popayán a través de 11 rutas, provenientes de los municipios de Sotará, Puracé y Coconuco, principales proveedores de leche cruda al Municipio de Popayán, mediante la técnica de Ring Test para detectar anticuerpos específicos antibrucella y se aplicó una encuesta estructurada a los due os de los hatos. La Prevalencia encontrada en este estudio fue del 15% (37/247). Los factores que se asociaron significativamente (p < 0.05) con la presencia de brucelosis en la leche cruda expendida en el Municipio de Popayán fueron: leche proveniente del Municipio de Sotará 25%(21/84), leche comercializada a través de la ruta 3 con 58.3% (7/11), nutrición solo con pasto 40% (4/10), convivencia con especies menores 23.2% (13/56), vacunador inadecuado 27.8% (10/36) y retención de placenta 26.1% (6 /23). La Prevalencia encontrada en el estudio con la Técnica Ring Test (15 %) es mayor que la reportada en estudios anteriores con la Técnica Elisa Indirecta (5%) para el Departamento del Cauca. La presencia de brucelosis podría asociarse con la procedencia de la leche cruda, la nutrición de los animales, convivencia con especies menores, vacunación y retención de placenta; factores condicionantes y predisponentes que hacen parte del proceso productivo de leche, los cuales pueden prevenirse y controlarse mediante el establecimiento de medidas sanitarias pertinentes.

Abstract: the cattle brucellosis is a highly contagious zoonosis and it is greatly released in the world according to world health organization (who). this disease causes important looses in the production, reproduction of dayri cattle. in humans it affects the health, productivity and human quality. this article aims at determining the prevalence of brucellosis in raw milk that is expended in the city of popayán and identificate the factors associated with the presence of brucellosis in the different raw milk provider herds. at descriptive study of cross-cutting was carried out. there were evaluated 247 marketed samples of raw milk in the city of popayan by 11 routes, originating from the municipalities of sotará, puracé and coconuco, principal providers of raw milk in the city of popayan. the ring test technique was used for detecting specific antibrucella antibodies and a survey was applied to the owners of herds. the prevalence found in this study was of 15 percent (37/247). the factors associated significantly (p < 0.05) with the presence of brucellosis in raw milk expended in the city of popayán were: milk originated from the municipality of sotará 25%(21/84), marketed milk by the third route with 58.3% (7/11), only fed with grass 40% (4/10), coexistence with minor species 23.2% (13/56), inappropriate vaccinated 27.8% (10/36) and retained placenta 26.1% (6 /23). the prevalence found in the study with the ring test technique (15%) is greater than the reported in previous studies with indirect elisa technique (5%) for cauca department. the presence of brucellosis may be associated with the origin of raw milk, nutrition of the animals, coexistence with minor species, vaccination and retention of the placenta; conditioning and predisposing factors that make part of the production process of milk which can be prevented and controled by the stablishing of relevant sanitary measures
Using an Interactive Computer System to Support the Task of Building the Notions of Ratio and Proportion  [PDF]
Elena Fabiola Ruiz Ledesma
Creative Education (CE) , 2010, DOI: 10.4236/ce.2010.12017
Abstract: This article describes the design and general outcome of applying a computer system that includes interactive activities to the topics of ratio and proportion. The work was undertaken with Mexican students attending primary school grade six (11 year olds). In designing the activities, our work was based on the studies of researchers who have focused on such topics, as well as on the work of researchers in the field of computer sciences and education technology. Support of the activities designed is found in psycho-pedagogy, in knowledge of mathematics and in the fields of computer sciences and education technology.
Representation Registers in the Solution of Calculus Problems  [PDF]
Elena Fabiola Ruiz Ledesma
Creative Education (CE) , 2011, DOI: 10.4236/ce.2011.23036
Abstract: This article is derived from the research project registered under number 20110343 (Ruiz, 2011), and developed in Escuela Superior de Cómputo del Instituto Politécnico Nacional (IPN) (School of Computer Sciences of the National Poly-technical Institute of Mexico). The article reports on the problems found among Engineering students with respect to their resistance to using different representation registers when solving optimization problems in the Calculus Learning Unit. Use of such registers could help the students to build mathematics know ledge and to solve calculus problems. As a didactic strategy, simulations are used in an electronic environment in order to support the students by fostering their use of tabular, graphical and algebraic representation registers. Interviews are undertaken of six of the professors who give the calculus courses, and a diagnostic questionnaire is applied to 68 students prior to and after working with the proposal. As for the theoretical framework, the work reported by Duval and Hitt is salient in this report, particularly their emphasis of the fact that working on activities by way of one single representation system is not sufficient. From the first responses provided by the students, one can conclude that the algebraic register is preferred by the majority of students. It is however used in a mechanical fashion without affording any meaning to the content of the problem and to the process of solving it. Another conclusion reported is that implementing tasks in the classroom in which the mathematics activity requires coherent use of different representations is necessary.
Primary and Secondary Teachers’ Knowledge, Interpretation, and Approaches to Students Errors about Ratio and Proportion Topics  [PDF]
Elena Fabiola Ruiz Ledesma
Creative Education (CE) , 2011, DOI: 10.4236/ce.2011.23035
Abstract: This study investigated elementary and secondary teachers’ understanding and pedagogical strategies applied to students making errors in finding a missing length in similar rectangles. It was revealed that secondary teachers had better understanding of ratio and proportion in similar rectangles than elementary teachers. While all secondary teachers solved the similar rectangles problems correctly, a large portion of elementary teacher struggled with the problem. In explaining their solution strategies, and even though similar strategies appeared both from elementary teachers and secondary teachers, a majority of secondary teachers pointed out the underlying idea of similarity, whereas less than half of the elementary teachers explained their reasoning for using ratios and proportion. This article is derived from the research project registered under number 20110343 (Ruiz, 2011), and developed in Escuela Superior de Cómputo del Instituto Politécnico Nacional (IPN) (School of Computer Sciences of the National Poly-technical Institute of Mexico)
A Cognitive Analysis When the Students Solve Problems  [PDF]
Elena Fabiola Ruiz Ledesma
Creative Education (CE) , 2012, DOI: 10.4236/ce.2012.34063
Abstract: The research reported in this paper shows an analysis of the cognitive process of students from the senior technical program on food technology, whom are asked to solve a contextualized event on systems of linear algebraic equations within the context of balance of matter in situations of chemical mixtures. The cognitive analysis is founded on the theories of Conceptual Fields and vents. For the analysis attention is focused on the representations carried out by students regarding the invariants in the schemes that they build when they face an event of contextualized mathematics. During the acting process of students emerge different types of representation which are appropriate to the context in which the research develops, with which a proposal for the classification of them.

Ceballos,Alvaro;
Historia (Santiago) , 2008, DOI: 10.4067/S0717-71942008000100002
Abstract: between 1881 and 1905 the germán publishing company f. a. brockhaus, issued one million textbooks for chilean educational institutions under the direction of josé abelardo nú?ez. what started as a way of funding his own research-stay in europe, quickly became a tremendous enterprise of cultural nationalization. profit-making, patriotism, nationalism and international capitalism merged to make possible these germán editions. this paper reconstructs at length the origin and motivations behind the publication of these books using previously unpublished correspondence and archival documentation.
LAS DOS AMéRICAS: RE-DESCUBRIMIENTO DEL NUEVO MUNDO
CEBALLOS,RENé;
Atenea (Concepción) , 2007, DOI: 10.4067/S0718-04622007000200005
Abstract: one of the main characteristics in the narrative of carlos fuentes is his playful treat ment of history. his conception of history is not limited just to the reproduction of dates and events. on the contrary, his re-presentation of history is above all a cultural recodification of history and literature leading to a hybrid state in which the two disciplines cannot be separated from one another. this is clearly the case that is presented in the novel el naranjo, whose chapter "las dos américas" is analyzed here
