O papel da certifica����o NP 4427:2004 no desenvolvimento das pr��ticas de gest��o de recursos humanos em organiza����es portuguesas

Este estudo tem como objetivo determinar o papel que a certifica����o pela Norma Portuguesa 4427:2004 ��� ���Sistemas de Gest��o de Recursos Humanos ��� requisitos��� (NP 4427:2004) assume no desenvolvimento das pr��ticas de Gest��o de Recursos Humanos. Neste sentido, foi realizada uma abordagem te��rica �� evolu����o temporal e conceptual da Gest��o de Recursos Humanos e identificadas as melhores pr��ticas que reconhecem nas pessoas um indispens��vel e estrat��gico ativo organizacional. Posteriormente �� apresentada a NP 4427:2004 e o seu enquadramento no contexto organizacional portugu��s. Apresentando-se como uma tem��tica moderna no ��mbito da Gest��o de Recursos Humanos, o presente estudo questiona se as empresas certificadas pela NP 4427:2004 promovem pr��ticas de Recursos Humanos estrat��gicas, se o grau de interven����o destes Departamentos, no desenvolvimento das pr��ticas, �� maior nas empresas certificadas pela NP 4427:2004, e se os respons��veis destes setores possuem qualifica����o espec��fica na ��rea de Recursos Humanos. A um universo de 95 empresas foi aplicado um inqu��rito por question��rio, que permitiu concluir que as organiza����es certificadas pela NP 4427:2004 promovem pr��ticas de Recursos Humanos estrat��gicas e envolvem Departamentos de Recursos Humanos com elevado grau de interven����o no desenvolvimento das mesmas, sendo que os seus Respons��veis n��o possuem forma����o espec��fica na ��rea dos Recursos Humanos.

An approach for reliability-based robust design optimisation of angle-ply composites

Variations of manufacturing process parameters and environmental aspects may affect the quality and performance of composite materials, which consequently affects their structural behaviour. Reliability-based design optimisation (RBDO) and robust design optimisation (RDO) searches for safe structural systems with minimal variability of response when subjected to uncertainties in material design parameters. An approach that simultaneously considers reliability and robustness is proposed in this paper. Depending on a given reliability index imposed on composite structures, a trade-off is established between the performance targets and robustness. Robustness is expressed in terms of the coefficient of variation of the constrained structural response weighted by its nominal value. The Pareto normed front is built and the nearest point to the origin is estimated as the best solution of the bi-objective optimisation problem.

Teamwork and Gendered Work Cultures: The Case of Finland

In this article I focus on women workers��� experiences of transformation from line work to teamworking in Finnish clothing companies in the 1990s and also show what happened after this transformation in the clothing branch. The undertone of it is rather melancholic. Following an initial period of intensive and successful development, clothing work was moved from Finland to countries of cheap labour, such as Estonia, Latvia, Lithuania and Russia, and even China. In this type of network manufacturing, the development of modern information and communication technologies played a central role. My aim is to present the standpoint of women clothing workers in this process. The main body of the empirical data of my study consists of dialogues with clothing workers, union representatives, supervisors and managers. I also make use of my fieldwork notes, memos and research diaries from three companies over a period of five years. Furthermore, in the background lie the action research material from Scandinavian type work conferences and the survey material of an extensive mail inquiry that covered the whole branch in Finland. My own research started in 1991 as a mail inquiry and then continued as a case study in companies from 1992 to 2000, by employing action research and ethnographic methodologies.

Dynamic QoS adaptation of inter- dependent task sets in cooperative embedded systems

Due to the growing complexity and dynamism of many embedded application domains (including consumer electronics, robotics, automotive and telecommunications), it is increasingly difficult to react to load variations and adapt the system's performance in a controlled fashion within an useful and bounded time. This is particularly noticeable when intending to benefit from the full potential of an open distributed cooperating environment, where service characteristics are not known beforehand and tasks may exhibit unrestricted QoS inter-dependencies. This paper proposes a novel anytime adaptive QoS control policy in which the online search for the best set of QoS levels is combined with each user's personal preferences on their services' adaptation behaviour. Extensive simulations demonstrate that the proposed anytime algorithms are able to quickly find a good initial solution and effectively optimise the rate at which the quality of the current solution improves as the algorithms are given more time to run, with a minimum overhead when compared against their traditional versions.

A trader portfolio optimization of bilateral contracts in electricity retail markets

Electricity markets are systems for effecting the purchase and sale of electricity using supply and demand to set energy prices. Two major market models are often distinguished: pools and bilateral contracts. Pool prices tend to change quickly and variations are usually highly unpredictable. In this way, market participants often enter into bilateral contracts to hedge against pool price volatility. This article addresses the challenge of optimizing the portfolio of clients managed by trader agents. Typically, traders buy energy in day-ahead markets and sell it to a set of target clients, by negotiating bilateral contracts involving three-rate tariffs. Traders sell energy by considering the prices of a reference week and five different types of clients. They analyze several tariffs and determine the best share of customers, i.e., the share that maximizes profit. �� 2014 IEEE.

Optimal location of the workpiece in a PKM-based machining robotic cell

Most machining tasks require high accuracy and are carried out by dedicated machine-tools. On the other hand, traditional robots are flexible and easy to program, but they are rather inaccurate for certain tasks. Parallel kinematic robots could combine the accuracy and flexibility that are usually needed in machining operations. Achieving this goal requires proper design of the parallel robot. In this chapter, a multi-objective particle swarm optimization algorithm is used to optimize the structure of a parallel robot according to specific criteria. Afterwards, for a chosen optimal structure, the best location of the workpiece with respect to the robot, in a machining robotic cell, is analyzed based on the power consumed by the manipulator during the machining process.

The simple economics of risk-sharing agreements between the NHS and the pharmaceutical industry

The Janssen-Cilag proposal for a risk-sharing agreement regarding bortezomib received a welcome signal from NICE. The Office of Fair Trading report included risk-sharing agreements as an available tool for the National Health Service. Nonetheless, recent discussions have somewhat neglected the economic fundamentals underlying risk-sharing agreements. We argue here that risk-sharing agreements, although attractive due to the principle of paying by results, also entail risks. Too many patients may be put under treatment even with a low success probability. Prices are likely to be adjusted upward, in anticipation of future risk-sharing agreements between the pharmaceutical company and the third-party payer. An available instrument is a verification cost per patient treated, which allows obtaining the first-best allocation of patients to the new treatment, under the risk sharing agreement. Overall, the welfare effects of risk-sharing agreements are ambiguous, and care must be taken with their use.

Energy efficiency of quadruped gaits

This paper studies periodic gaits of quadruped locomotion systems. The purpose is to determine the best set of gait and locomotion variables during walking, for different robot velocities, based on two formulated performance measures. A set of experiments reveals the influence of the gait and locomotion variables upon the proposed indices, namely that the gait and the locomotion parameters should be adapted to the robot forward velocity.
