Recurso Electr?nicoEste trabajo de grado consiste en realizar una aproximaci?n ling??stica hacia el discurso originado a partir de los enunciados verbales y no verbales creados por los estudiantes de los grados 6-1 y 6-7 de la Instituci?n T?cnica Francisco de Paula Santander, de la ciudad de Ibagu?, en espacios escolares con el fin de divulgarlos y realizarles un an?lisis l?xico, pragm?tico, semi?tico y socioling??stico en pro de mostrar los cambios que permanentemente sufre el lenguaje y como este influye en las estructuras sociales y culturales. El trabajo consta de tres etapas b?sicamente, por medio de las cuales se desarroll? el dise?o metodol?gico, la primera de ellas va enfocada a la contextualizaci?n de la Instituci?n T?cnica Educativa Francisco de Paula Santander de la ciudad de Ibagu? y la zona residencial en donde esta se encuentra. La segunda etapa da a conocer todo lo relacionado a las fases que se implementaron, con base al documento ?Redescubrir la Escuela? que se dieron a trav?s, de los diferentes semestres de la carrera universitaria ?Licenciatura en Educaci?n B?sica con ?nfasis en Lengua Castellana?. La ?ltima secci?n presenta ?el taller?, como estrategia metodol?gica en la intervenci?n realizada en el aula de clases, con un fin espec?fico y, es el de elaborar expresiones orales y graficas propias del discurso de los alumnos mencionados anteriormente, a partir de la implementaci?n de medios tem?ticos como lo son la m?sica, la literatura y el cortometraje. Palabras Claves: Discurso, Estudiantes, Contexto Socio Cultural, Simbolismo, intenciones comunicativas.This degree work is to conduct a linguistic approach to speech originated from verbal statements and nonverbal created by students in grades 6-1 and 6-7 of the Technical Institution Francisco de Paula Santander, city Ibague, in school areas in order to disseminate and have a follow lexical, pragmatic and sociolinguistic analysis in favor of showing the changes permanently suffer the language and how it affects the social and cultural structures. The work consists of three stages basically, through which the methodological design was developed, the first one is focused on the contextualization of the Educational Technical Institution Francisco de Paula Santander city of Ibague and the residential area where this is find. The second stage disclosed everything related to the phases that were implemented, based on the document "Rediscovering School" that got through, the different semesters of university studies "Degree in Basic Education with Emphasis in Spanish Language" . The final section presents "workshop" as a methodological strategy for intervention in the classroom, with a specific purpose and is to develop oral expressions and graphs own speech of students mentioned above, from the implementation thematic media such as music, literature and film.

Wage inequality, segregation by skill and the price of capital in an assignment model

Some pieces of empirical evidence suggest that in the U.S., over the last few decades, (i) wage inequality between-plants has risen much more than wage inequality within-plants and (ii) there has been an increase in the segregation of workers by skill into separate plants. This paper presents a frictionless assignment model in which these two features can be explained simultaneously as the result of the decline in the relative price of capital. Additional implications of the model regarding the skill premium and the dispersion in labor productivity across plants are also consistent with the empirical evidence. [resumen de autor

The labor market effects of technology shocks

We analyze the effects of neutral and investment-specific technology shocks on hours worked and unemployment. We characterize the response of unemployment in terms of job separation and job finding rates. We find that job separation rates mainly account for the impact response of unemployment while job finding rates for movements along its adjustment path. Neutral shocks increase unemployment and explain a substantial portion of unemployment and output volatilityinvestment-specific shocks expand employment and hours worked and mostly contribute to hours worked volatility. We show that this evidence is consistent with the view that neutral technological progress prompts Schumpeterian creative destruction, while investment specific technological progress has standard neoclassical feature

Improved pastures for cattle rising in the Jucuapa river subwatershed, Nicaragua

6 ilus. 1 tab. 20 ref.Se estudi? el crecimiento de las pasturas mejoradas Brachiaria brizantha {D7} Brachiaria ruziziencis y Brachiaria brizantha y la leguminosa Cratylia argentea bajo las condiciones agroecol?gicas de la parte media de la subcuenca del r?o Jucuapa, Nicaragua, y dos sistemas de siembra: directa y por transplante. Como pastura de referencia se utiliz? la especie nativa Hyparrhenia rufa. Las pasturas mejoradas establecidas por transplante tuvieron una mejor cobertura del suelo y un mayor n?mero de macollas, en comparaci?n con la pastura nativa. Con cualquier sistema de siembra, los forrajes mejorados tuvieron mayores rendimientos de materia seca en comparaci?n con los rendimientos de la pastura nativa. El crecimiento de Cratylia argentea no mostr? diferencias significativas entre formas de establecimiento. The growth of Brachiaria brizantha {D7} Brachiaria ruziziencis and Brachiaria brizantha pastures and of the leguminous Cratylia argentea was studied under the agro-ecological conditions prevailing in the central part of the Jucuapa river subwatershed, Nicaragua two planting systems were evaluated: direct sowing and transplant. The native species Hyparrhenia rufa was used as reference. Improved pastures established by transplant showed a better soil cover and a bigger number of shoots than the native pasture. Dry matter yields of improved pastures were much better than those of the native species. Cratylia argentea did not show significant changes in growth, whether established directly or transplanted

Participative evaluation of promising forage crops for dry zones, and expected impacts on natural resources in Jucuapa River subwatershed, Nicaragua

3 ilus. 12 ref.Se desarroll? un proceso de investigaci?n-acci?n con productores ganaderos y funcionarios, con el fin de evaluar el comportamiento y el potencial de dos pasturas y una leguminosa para mejorar la calidad y cantidad de alimento para el ganado, reducir la degradaci?n de los recursos naturales y favorecer las condiciones socioecon?micas de los productores ganaderos en la subcuenca del r?o Jucuapa, Nicaragua. Las especies evaluadas fueron las pasturas Brachiaria brizantha x Brachiaria ruziziencis y Brachiaria brizantha y la leguminosa Cratylia argentea bajo dos sistemas de siembra: transplante y siembra directa. La metodolog?a participativa incluy?: establecimiento de parcelas demostrativas, d?as de campo, entrevistas y un taller participativo.Los productores ganaderos mostraron mucho inter?s en continuar con el establecimiento de B. brizantha x B. ruziziencis y B. brizantha y un menor inter?s en C. argentea. A participative actionresearch process was developed with participation of farmers and institutional officers in Jucuapa River subwatershed, Nicaragua, with the purpose of evaluating the behavior and potential of two pastures and a leguminous for improving the quality and quantity of cattle feeding, reducing natural resources degradation, and improving livelihood conditions. The species evaluated were the pastures Brachiaria brizantha x Brachiaria ruziziencis and Brachiaria brizantha, and the leguminous Cratylia argentea two planting system (transplant and direct planting) were evaluated. The participative methodology included the establishment of demonstrative plots, field trips, interviews, and a participative workshop. Farmers were highly interested on B. brizantha x B. ruziziencis and B. brizantha, but less interested on C. argentea

Error Cascades in Observational Learning: An Experiment on the Chinos Game

The paper reports an experimental study based on a variant of the popular Chinos game, which is used as a simple but paradigmatic instance of observational learning. There are three players, arranged in sequence, each of whom wins a fixed price if she manages to guess the total number of coins lying in everybody?s hands. Our evidence shows that, despite the remarkable frequency of equilibrium outcomes, deviations from optimal play are also significant. And when such deviations occur, we find that, for any given player position, the probability of a mistake is increasing in the probability of a mistake of her predecessors. This is what we call an error cascade, which we which we measure by way of two alternative models.positional learning, error cascades
