Authoritarianism and labor market : preference of labor policies in the Arab Gulf countries

Migrant and labor issues are a primary concern in the Arab Gulf countries. With focus on the economic and political conditions that influence actors' decisions when framing labor policies, this study analyzes how preferences of such policies are formed and explains why the governments of the Arab Gulf countries attempt to implement less economical policies. The findings suggest that governments avoid concessions for enterprises required to implement more economical policies and chose uneconomical ones to maintain authoritarian regimes.

Land and labor reallocation in pre-modern Japan : a case of a northeastern village in 1720-1870

In agricultural societies, adjusting land and labor according to changes of labor endowment that result from family life cycle events is premised on making full use of resources for each farming household and for the economy as a whole. This paper examines how and how well households in pre-modern Japan reallocated land and labor, using a population register covering 150 years from 1720–1870 for a village in the Tohoku region. We find that households reacted to equalize their production factors; land-scarce households tended to acquire or rent-in land and out-migrate their kin members, while land-abundant households tended to release or rent-out land, in-migrate kin members, or employ non-kin members. Estimates suggest that more than 80% of the surplus or deficit area of land was resolved if the household rented or "sold" land. We discuss a potential underlying mechanism; namely, that the village's collective responsibility for tax payment (murauke) motivated both individual households and the village as a whole to reallocate land and labor for the efficient use of resources.

What best transfers knowledge? : capital, goods, and innovative labor in East Asia

This paper compares three knowledge carriers—trade, foreign direct investment (FDI), and inventors—as knowledge mediums, and investigates their effects on knowledge flow in East Asia from 1996 to 2010. Using patent citations as a proxy for knowledge flow, this paper shows that FDI and inventor mobility have positive effects on increasing patent citations in East Asia when the technological portfolios of two countries are less similar. While trade shows statistical significance, the effect is inconsistent according to the regression models.

Fundamentación del conjunto tractor-apero para la labor de surcado y su influencia en el consumo energético en cultivos de raíces y tubérculos

El cumplimiento de los objetivos agrotécnicos de los cultivos de raíces y tubérculos exige que la labor de surcado configure un caballón que permita el trabajo de los posteriores aperos que participan en las demás labores de cultivo. En la agricultura cubana se emplean diversos tipos de surcadores que difieren en las características de los elementos aporcadores. Este hecho afecta a la capacidad de trabajo del conjunto tractor-apero y por extensión en el consumo de combustible y el rendimiento del cultivo. El objetivo de este trabajo ha sido fundamentar el empleo del apero más adecuado para la labor de surcado en cultivos de raíces y tubérculos (patata, boniato, yuca) en Fluvisoles, teniendo en cuenta el comportamiento de las dimensiones y forma del caballón, cualidades tecnológicas explotativas del conjunto tractor-apero, consumo energético del proceso productivo y el rendimiento agrícola. Los tratamientos considerados estuvieron determinados por la utilización del surcador fertilizador IIMA-BALDAN 4.500 (T1), y los surcadores aporcadores SA-5 (T2) y SA-3 (T3). En los tres tratamientos se alcanzó un perfil de la sección transversal del caballón de configuración cóncavo-convexo. El surcador BALDAN logró el mejor comportamiento de los indicadores tecnológico-explotativos lo que se tradujo en la mayor capacidad de trabajo de 1,36 ha h-1 y el menor consumo de combustible de 5,38 L ha-1. Este mismo tratamiento proporcionó el mayor rendimiento medio de los cultivos superando en un 43,2% al del surcador SA-5 y en un 57,9% al del surcador SA-3. Desde el punto de vista energético T1, obtuvo una mejor eficiencia energética superior en un 43,5% a la del tratamiento T2, y en un 57,1% a la del tratamiento T3. ABSTRACT The achievement of agrotechnical objectives in the cultivation of roots and tubers demands the plow through activity creates a ridge to allow the work of subsequent farming tools participating in other cultivation works. In Cuban Agriculture various kinds of furrowers are used which differ in the characteristics of their earth up elements. This fact affects work capacity of the tractor-farming tool combination and by extension to fuel consumption and cultivation yield. The aim of this work has been to support the use of the most accurate farming tool in the plow through activity for the cultivation of roots and tubers (potato, sweet potato, cassava) in Fluvisoils, taking into account the behaviour of the ridge´s dimensions and shape, technologic-explotative qualities of the tractor-farming tool combination, energy consumption of the productive process and agricultural yield. The treatments considered were determined by the use of fertlizing furrower IIMA-BALDAN 4.500 (T1), and the earth up furrowers SA-5 (T2) and SA-3 (T3). During the three treatments a transverse section profile of the ridge under concave-convex configuration was obtained. The furrower BALDAN achieved the best behaviour of the technologic-explotative indicators, which was translated into the largest work capacity of 1,36 ha h-1 and the smallest fuel consumption of 5,38 L ha-1. This treatment also provided the biggest average yield of the cultivation, overcoming in a 43,2% the furrower SA-5 and furrower SA-3 in a 57,9%. From the energetic point of view T1 gained better energetic efficiency than treatment T2 in a 43,5% and treatment T3 in a 57,1%.

La nueva norma UNE 153010. Una labor de consenso

La norma UNE 153010:2003 recogía requisitos para el subtitulado para personas sordas a través de teletexto. Fue el resultado de varios años de trabajo en el Subcomité 5 del Comité Técnico de Normalización (CTN) 153 de AENOR. Los cambios en los últimos años en cuanto a los medios audiovisuales llevaron a dicho Subcomité a plantearse en el año 2008 la posibilidad de actualizar los contenidos de esta norma, con el fin de adaptarse a nuevas tecnologías, como los DVD, la televisión digital o la televisión emitida a través de Internet. Inicialmente se planteó la posibilidad de realizar normas específicas de subtitulado para cada tecnología de emisión, pero finalmente se decidió desarrollar una norma general de subtitulado que fuera de aplicación general. Tras un largo periodo de trabajo, la nueva versión de la norma UNE 153010 está a punto de ver la luz, dado que se encuentra en periodo de información pública. En este artículo se narra el proceso de desarrollo de esta norma y se describe los aspectos más importantes de la misma, resultado de una intensa labor con gran voluntad de consenso por parte de las entidades implicadas.

Assessment of irrigators’ preferences for different water supply risk management tools: option contract and insurance.

Irrigators face the risk of not having enough water to meet their crops’ demand. There are different mechanisms to cope with this risk, including water markets (option contracts) or insurance. A farmer will purchase them when the expected utility change derived from the tool is positive. This paper presents a theoretical assessment of the farmer’s expected utility under two different option contracts, a drought insurance and a combination of an option contract and the insurance. We analyze the conditions that determine farmer’s reference for one instrument or the other and perform a numerical application that is relevant for a Spanish region.

Variable threshold algorithm for division of labor analyzed as a dynamical system

Division of labor is a widely studied aspect of colony behavior of social insects. Division of labor models indicate how individuals distribute themselves in order to perform different tasks simultaneously. However, models that study division of labor from a dynamical system point of view cannot be found in the literature. In this paper, we define a division of labor model as a discrete-time dynamical system, in order to study the equilibrium points and their properties related to convergence and stability. By making use of this analytical model, an adaptive algorithm based on division of labor can be designed to satisfy dynamic criteria. In this way, we have designed and tested an algorithm that varies the response thresholds in order to modify the dynamic behavior of the system. This behavior modification allows the system to adapt to specific environmental and collective situations, making the algorithm a good candidate for distributed control applications. The variable threshold algorithm is based on specialization mechanisms. It is able to achieve an asymptotically stable behavior of the system in different environments and independently of the number of individuals. The algorithm has been successfully tested under several initial conditions and number of individuals.

AS INTERFACES DA PROMOÇÃO DA SAÚDE E UM PROGRAMA DE APRENDIZAGEM PROFISSIONAL

O trabalho desenvolvido com adolescentes, pensando na promoção de sua saúde, bem como em seu desenvolvimento saudável por meio de espaços que atendam suas necessidades, tem sido de responsabilidade também de organizações sociais. Em especial, quando se tem o objetivo de prepará- los para o mundo do trabalho, porém com uma proposta mais ampla, ou seja, como uma preparação para suas relações na vida, pela passagem de um processo de aprendizagem, de amadurecimento, por meio da construção de ações significativas para vida. Esta é a proposta do Centro de Orientação ao Adolescente de Campinas COMEC , organização não governamental, que conta com um Progr ama de Aprendizagem Profissional- PAP . Sendo assim, esse estudo tem como objetivo caracterizar, por meio de prontuários, uma amostra de 280 adolescentes, compreender a percepção deles no processo vivido e identificar as expectativas na admissão, demissão e desligamento do programa - PAP. A pesquisa teve como participantes adolescentes de 14 a 17 anos, do gênero feminino e masculino, do ensino fundamental e médio (7ª série E.F até 3ª série E.M). Os formulários foram preenchidos em três momentos: primeiro quando o adolescente participava da seleção para ingressar no programa, segundo, quando ele iniciava o trabalho na empresa e no término do contrato do adolescente com o programa. Os resultados obtidos por meio dos prontuários dos adolescentes mostraram que a percepção que eles têm a respeito do programa é positiva. Perceberam-se sentimentos de medo, insegurança, alegrias e desejos a respeito das atividades que os preparam para a inserção no mercado formal de trabalho, e o quanto o acompanhamento pelo programa permite outro olhar para esta inclusão. Ainda que o trabalho juvenil não seja a solução para as necessidades econômicas de muitas famílias, o trabalho educativo tem sido visto como uma forma de permitir que o adolescente vivencie sua primeira experiência de trabalho, respeitando sua condição de pessoa em desenvolvimento. Porém, em alguns casos, acabam por contribuir de forma significativa no orçamento familiar.(AU)
