Algunos de los fenómenos donde el concepto de “globalización” es aplicado incluyen la internacionalización de los mercados, la globalización de la cultura, el dominio político hegemónico del mundo por algunos estados poderosos, o grupos de estados, el poder creciente de organismos supranacionales, y el desarrollo de una división global de trabajo. De acuerdo con Radice, la globalización é generalmente definida como “un proceso a través de lo cual una proporción creciente de transacciones económicas, sociales e culturales ocurre directamente o indirectamente entre partners de países distintos” (Radice, 2004: 154). Un ponto de partida para entender la división global del trabajo debe ser la investigación de los modos como las empresas se reestructuran, una vez que son los actores-llave en la decisión sobre que trabajo debe ser encontrado y donde. Las “cadenas de valor” descriven cada etapa en el proceso productivo de un producto o un servicio final. La palabra “valor” en la frase “cadena de valor” dice respecto al valor añadido. Cada etapa en la cadena de valor implica recibir inputs, procesarlos, y entonces pasarlos a la unidad siguiente en la cadena, con el valor que está sendo adicionado no proceso. As unidades separadas da cadena de valor pueden estar dentro da misma empresa (in-house) o en distintas empresas (outsourced). Similarmente pueden estar en un mismo local, o en otra localización. La normalización de muchos procesos del negocio, combinada con la digitalización da información y el desarrollo de redes de telecomunicaciones de elevada capacidad ha tornado posible el trabajo tele-mediado, pudiendo este ser externalizado y/o re-localizado, conduciendo à introducción de una división de trabajo internacional no trabajo de procesamiento de información. Esta comunicación presentará algunos resultados derivados do proyecto europeo WORKS, donde son estudiados casos portugueses de empresas que justamente se integran en

This paper presents the performances of an in-line plasma enhanced chemical vapor deposition system constituted by 5 chambers and one external unloaded chamber used in the simultaneous manufacturing of 4 large (30 cm × 40 cm) solar cells deposited on glass substrates. The system is fully automatically controlled by a Programmable Logic Controller using a specific developed software that allows devices mass production without losing the flexibility to perform process innovations according to the industrial requests, i.e. fast and secure changes and optimizations. Overall, the process shift is of about 15 min per each set of 4 solar cells. Without a buffer layer, solar cells with efficiencies of about 9% were produced by the proper tuning of the i-layer production conditions. © 2005 Elsevier B.V. All rights reserved.

In this work metal induced crystallization (MIC) using nickel (Ni) was employed to obtain poly-Si by crystallization of amorphous films for application as active layer in TFTs. Ni layers with thicknesses of 0.5 nm, 1 nm and 2 nm were used to crystallize the silicon. The TFTs were produced with a bottom gate configuration using a multi-layer Al2O3/TiO2 insulator produced by atomic layer deposition (ALD) as gate dielectric. The best performances of the TFT produced were obtained when using very thin Ni layers for the crystallization. This is attributed to a lower metal contamination and to the enhancement of grain size, as a result of the lower nucleation density achieved, when using the thinnest Ni layer. Devices that exhibit effective mobility of 45.5 cm2V-1s-1 and an on/off ratio of 5.55×104 were produced using a 0.5 nm Ni layer to crystallize the active channel area.

The aim of the TeleRisk Project on labour relations and professional risks within the context of teleworking in Portugal – supported by IDICT – Institute for Development and Inspection of Working Conditions (Ministry of Labour), is to study the practices and forms of teleworking in the manufacturing sectors in Portugal. The project chose also the software industry as a reference sector, even though it does not intend to exclude from the study any other sector of activity or the so-called “hybrid” forms of work. However, the latter must have some of the characteristics of telework. The project thus takes into account the so-called “traditional” sectors of activity, namely textile and machinery and metal engineering (machinery and equipment), not usually associated to this type of work. However, telework could include, in the so-called “traditional” sectors, other variations that are not found in technologically based sectors. One of the evaluation methods for the dynamics associated to telework consisted in carrying out surveys by means of questionnaires, aimed at employers in the sectors analysed. This paper presents some of the results of those surveys. It is important to mention that, being a preliminary analysis, it means that it does not pretend to have exhausted all the issues in the survey, but has meant that it shows the bigger tendencies, in terms of teleworking practices, of the Portuguese industry.
