Auction of financial transmission rights in electricity market environment

An auction model is used to increase the individual profits for market players with products they do not use. A Financial Transmission Rights Auction has the goal of trade transmission rights between Bidders and helps them raise their own profits. The ISO plays a major rule on keep the system in technical limits without interfere on the auctions offers. In some auction models the ISO decide want bids are implemented on the network, always with the objective maximize the individual profits for all bidders in the auction. This paper proposes a methodology for a Financial Transmission Rights Auction and an informatics application. The application receives offers from the purchase and sale side and considers bilateral contracts as Base Case. This goal is maximize the individual profits within the system in their technical limits. The paper includes a case study for the 30 bus IEEE test case.

A long-term risk management tool for electricity markets using swarm intelligence

This paper addresses the optimal involvement in derivatives electricity markets of a power producer to hedge against the pool price volatility. To achieve this aim, a swarm intelligence meta-heuristic optimization technique for long-term risk management tool is proposed. This tool investigates the long-term opportunities for risk hedging available for electric power producers through the use of contracts with physical (spot and forward contracts) and financial (options contracts) settlement. The producer risk preference is formulated as a utility function (U) expressing the trade-off between the expectation and the variance of the return. Variance of return and the expectation are based on a forecasted scenario interval determined by a long-term price range forecasting model. This model also makes use of particle swarm optimization (PSO) to find the best parameters allow to achieve better forecasting results. On the other hand, the price estimation depends on load forecasting. This work also presents a regressive long-term load forecast model that make use of PSO to find the best parameters as well as in price estimation. The PSO technique performance has been evaluated by comparison with a Genetic Algorithm (GA) based approach. A case study is presented and the results are discussed taking into account the real price and load historical data from mainland Spanish electricity market demonstrating the effectiveness of the methodology handling this type of problems. Finally, conclusions are dully drawn.

Hospital volunteers ��� are they satisfied?

We examine satisfaction with HRM practices, namely recruitment, training and rewarding in NPO���s and attitudes regarding the appropriateness of these practices. The participants in this study are 76 volunteers, affiliated to 4 different NPO���s, which work in hospitals and have direct contact with patients and their families. Analysing aggregate results we show that volunteers are more satisfied with training, and consider that the training strategies are very appropriate. After identifying differences between organisations we discover that in some organizations volunteers are satisfied with rewards, but in opposition they have negative attitudes regarding the appropriateness of the recognition strategies and vice-versa an opposite relation between satisfaction with reward and recognition strategies and the process of reward and recognition. We also name the more and less satisfied volunteers.

Organisational influence on volunteer satisfaction and attitudes towards HRM practices: the case of hospital volunteers

We also identify the volunteers who are the most and the least satisfied.

Indicadores de gest��o em cuidados intensivos

As unidades de cuidados intensivos (UCI), s��o das ��reas hospitalares que mais dinheiro consomem nas institui����es p��blicas. As fun����es dos profissionais de sa��de s��o imprescind��veis, mas tamb��m a log��stica e gest��o s��o de vital import��ncia e como tal, t��m de ser avaliadas. Por isso, todos os indicadores ��� cl��nicos, econ��mico-financeiros, recursos humanos, produtividade, qualidade - s��o importantes para que a gest��o possa, din��mica e oportunamente, ter informa����o ��til para a tomada de decis��es. Assim, a garantia de uma gest��o eficiente dos recursos �� cada vez mais importante de forma a satisfazer n��o s�� os pacientes como toda a estrutura hospitalar. Nos tempos que correm, e com a situa����o socioecon��mica de crise que se vive, �� de extrema import��ncia saber com o maior n��vel de detalhe poss��vel, com que recursos se pode contar. �� importante quantificar de forma eficaz e eficiente como s��o utilizados os recursos, para satisfazer com o maior n��vel de qualidade poss��vel um paciente que entre numa UCI. Para tal, a utiliza����o de sistemas de informa����o (SI) e das ferramentas indicadas na gest��o de uma unidade hospitalar, s��o de grande import��ncia. Nesta tese, �� proposta uma ferramenta, que seja simples e de f��cil utiliza����o, desenvolvida com recurso a tecnologia ROLAP para a extrac����o e an��lise de indicadores numa UCI, e que possa ser facilmente integrada num software de gest��o do dia-a-dia.

Lideran��a aut��ntica e sa��de organizacional: um estudo de caso num hospital

O conceito de Lideran��a tem sido amplamente estudado por diversos autores, sendo j�� considerado pela literatura como um tema cl��ssico evolutivo. A investiga����o que aqui se apresenta pretende compreender a mais recente abordagem a esse conceito - a Lideran��a Aut��ntica, no contexto espec��fico de um CH p��blico em Portugal. Al��m disso, �� seu prop��sito perceber se uma Lideran��a Aut��ntica �� preditora de um Clima Organizacional Autentiz��tico e se ambos os construtos explicam a Satisfa����o - com o trabalho em geral e com a supervis��o - e a Sa��de Mental dos trabalhadores. Procura, ainda, mediante an��lises explorat��rias, estudar a influ��ncia de algumas vari��veis demogr��ficas e profissionais na Lideran��a Aut��ntica, no Clima Organizacional Autentiz��tico, na Satisfa����o e na Sa��de. Participaram neste estudo de caso 278 trabalhadores, de diferentes grupos profissionais e v��nculos contratuais, tendo os resultados obtidos apontado para uma indubit��vel rela����o preditiva entre a Lideran��a Aut��ntica e a Satisfa����o com a Supervis��o, a Satisfa����o com o Trabalho em Geral e a Sa��de Mental. A Lideran��a Aut��ntica �� igualmente uma preditora significativa do Clima Organizacional Autentiz��tico. Este ��ltimo afigura-se, para a amostra, como explicativo de maior Satisfa����o e Sa��de Mental dos trabalhadores. No que respeita ao estudo das vari��veis demogr��ficas (sexo, idade, estado civil e habilita����es liter��rias) e profissionais (v��nculo contratual, grupo profissional, n��vel da organiza����o, antiguidade e sexo do superior hier��rquico) em fun����o das vari��veis em estudo (Lideran��a Aut��ntica, Clima Organizacional Autentiz��tico, Satisfa����o e Sa��de), concluiu-se que as mulheres evidenciam n��veis inferiores de Sa��de Mental, comparativamente aos homens. Os homens denotam menor perce����o de Lideran��a Aut��ntica que as mulheres. Os ���mais escolarizados��� evidenciam menor Sa��de Mental e maior perce����o de Lideran��a Aut��ntica que os ���menos escolarizados���. O grupo ���t��cnico de sa��de��� est�� mais satisfeito com o trabalho em geral mas evidencia menor Sa��de Mental que o grupo ���t��cnico operacional���. Os trabalhadores cuja chefia �� do sexo feminino demonstram n��veis inferiores de Sa��de Mental. Por fim, comparadas as perce����es de Lideran��a Aut��ntica entre chefias e trabalhadores n��o chefias, inferimos que s��o os primeiros a perceber os l��deres como mais aut��nticos. O estudo apresenta as suas conclus��es e aponta estrat��gias de interven����o em termos da Gest��o e Desenvolvimento e Recursos Humanos para o CH em investiga����o.

Environmental data management in the Sado Estuary

Estuaries are perhaps the most threatened environments in the coastal fringe; the coincidence of high natural value and attractiveness for human use has led to conflicts between conservation and development. These conflicts occur in the Sado Estuary since its location is near the industrialised zone of Peninsula of Set��bal and at the same time, a great part of the Estuary is classified as a Natural Reserve due to its high biodiversity. These facts led us to the need of implementing a model of environmental management and quality assessment, based on methodologies that enable the assessment of the Sado Estuary quality and evaluation of the human pressures in the estuary. These methodologies are based on indicators that can better depict the state of the environment and not necessarily all that could be measured or analysed. Sediments have always been considered as an important temporary source of some compounds or a sink for other type of materials or an interface where a great diversity of biogeochemical transformations occur. For all this they are of great importance in the formulation of coastal management system. Many authors have been using sediments to monitor aquatic contamination, showing great advantages when compared to the sampling of the traditional water column. The main objective of this thesis was to develop an estuary environmental management framework applied to Sado Estuary using the DPSIR Model (EMMSado), including data collection, data processing and data analysis. The support infrastructure of EMMSado were a set of spatially contiguous and homogeneous regions of sediment structure (management units). The environmental quality of the estuary was assessed through the sediment quality assessment and integrated in a preliminary stage with the human pressure for development. Besides the earlier explained advantages, studying the quality of the estuary mainly based on the indicators and indexes of the sediment compartment also turns this methodology easier, faster and human and financial resource saving. These are essential factors to an efficient environmental management of coastal areas. Data management, visualization, processing and analysis was obtained through the combined use of indicators and indices, sampling optimization techniques, Geographical Information Systems, remote sensing, statistics for spatial data, Global Positioning Systems and best expert judgments. As a global conclusion, from the nineteen management units delineated and analyzed three showed no ecological risk (18.5 % of the study area). The areas of more concern (5.6 % of the study area) are located in the North Channel and are under strong human pressure mainly due to industrial activities. These areas have also low hydrodynamics and are, thus associated with high levels of deposition. In particular the areas near Lisnave and Eurominas industries can also accumulate the contamination coming from ��guas de Moura Channel, since particles coming from that channel can settle down in that area due to residual flow. In these areas the contaminants of concern, from those analyzed, are the heavy metals and metalloids (Cd, Cu, Zn and As exceeded the PEL guidelines) and the pesticides BHC isomers, heptachlor, isodrin, DDT and metabolits, endosulfan and endrin. In the remain management units (76 % of the study area) there is a moderate impact potential of occurrence of adverse ecological effects and in some of these areas no stress agents could be identified. This emphasizes the need for further research, since unmeasured chemicals may be causing or contributing to these adverse effects. Special attention must be taken to the units with moderate impact potential of occurrence of adverse ecological effects, located inside the natural reserve. Non-point source pollution coming from agriculture and aquaculture activities also seem to contribute with important pollution load into the estuary entering from ��guas de Moura Channel. This pressure is expressed in a moderate impact potential for ecological risk existent in the areas near the entrance of this Channel. Pressures may also came from Alc��cer Channel although they were not quantified in this study. The management framework presented here, including all the methodological tools may be applied and tested in other estuarine ecosystems, which will also allow a comparison between estuarine ecosystems in other parts of the globe.

A import��ncia da gest��o baseada na cria����o de valor para o acionista (Value-Based Management): o caso do Grupo Galp Energia

A avalia����o de empresas sempre constituiu um tema de elevada reflex��o, sendo que v��rios especialistas tentam encontrar os modelos que melhor se adaptam a situa����es espec��ficas e para as quais precisam de determinar um valor. No contexto empresarial portugu��s come��a a ganhar signific��ncia a pr��tica da gest��o orientada para a cria����o de valor (Value-Based Management). O conceito de Value-Based Management assistiu a um particular desenvolvimento nos ��ltimos 20 anos como resultado da globaliza����o e desregulamenta����o dos mercados financeiros, dos avan��os nas tecnologias de informa����o e do aumento da import��ncia dos investidores institucionais. V��rios analistas apresentaram evid��ncia de que as empresas que adotam sistemas VBM melhoram o seu desempenho econ��mico em rela����o a outras de dimens��o semelhante no mesmo setor. �� neste contexto que o EVA (Economic Value Added) se apresenta como uma m��trica de desempenho privilegiada nos processos de controlo das decis��es estrat��gicas tomadas. No presente trabalho pretendemos abordar o conceito da gest��o baseada na cria����o de valor e a sua import��ncia para o acionista, o que implica rever outros modelos de avalia����o tradicionais baseados no valor contabil��stico. Como m��trica de avalia����o do desempenho passado da empresa ao n��vel da cria����o de valor vamos dar particular import��ncia ao estudo do EVA, fazendo refer��ncia �� poss��vel correla����o entre esta m��trica e o MVA (Market Value Added). O objetivo principal �� analisar empiricamente a rela����o do EVA como medida de desempenho associada �� cria����o de valor para os acionistas com a performance da empresa. Com efeito, vamos efetuar um estudo de caso, que vai incidir sobre um grupo empresarial portugu��s, refer��ncia no seu setor de atividade, o Grupo Galp Energia, cotado na Euronext Lisbon. Pensamos que a crescente pr��tica da gest��o baseada na cria����o de valor nas empresas cotadas em Portugal e a necessidade de aferir os resultados desta, tornam esta investiga����o pertinente, para al��m do facto de serem poucos os estudos emp��ricos �� quest��o da cria����o de valor e a sua correla����o com o valor acrescentado de mercado e com o valor de mercado dos capitais pr��prios das empresas cotadas em Portugal.
