Corruptos Submarinos: Portugal Envergonhado

Recordar é viver. O famoso caso de corrupção internacional ligado à compra e venda de submarinos pelo Estado português – e que ainda não está resolvido na sua totalidade, nomeadamente por cá – constitui um facto repugnante da história contemporânea da anti-corrupção, e da ética, também lusa que envergonha em profundidade Portugal a nível nacional, mas sobretudo internacional. E envergonha, quer o poder legislativo, quer o poder judicial, quer o poder executivo. Em Portugal, mas também na Alemanha, pois nem toda a informação criminal chegou às autoridades portuguesas como foi noticiado pelos próprios procuradores. § Remember is living. The famous case of international corruption linked to the purchase and sale of submarines by the Portuguese State - and that is still not resolved in its entirety, especially around here - is a disgusting fact of contemporary history of anti-corruption and ethics, also Portuguese who shames Portugal in depth at national level, but above all international. And shame either the legislature or the judiciary or the executive. In Portugal, but also in Germany, as not all criminal information came from the Portuguese authorities was as reported by their own attorneys.

Influence of discount price announcements on consumer's behavior

The theoretical framework that underpins this research study is based on the Prospect Theory formulated by Kahneman and Tversky, and Thaler's Mental Accounting Theory. The research aims to evaluate the consumers' behavior when different patterns of discount are offered (in percentage and absolute value and for larger and smaller discounts). Two experiments were conducted to explore these patterns of behavior and the results that were obtained supported the view that the framing effect was a common occurrence. The patterns of choice of individuals in a sample were found to be different due to changes in the ways discounts were offered. This can be explained by the various ways of presenting discount rates that had an impact on the influence of purchase intentions, recommendations and quality perception.

O conceito de valor para o consumidor : uma análise sob a óptica da metodologia Laddering

RESUMO: O constructo de customer value é aquele que melhor explica o comportamento do consumidor, uma vez que o seu objectivo é o de entender como os consumidores traduzem os atributos e consequências do uso de um produto em valores pessoais relevantes. A metodologia laddering, que tem como base a teoria das cadeias meios-fim, é um elemento teórico que se considera consistente para estabelecer a relação entre os atributos e os valores do consumidor. Esta dissertação pretende demonstrar a exequibilidade da metodologia laddering em estudos sobre o valor para o consumidor, percebendo quais são as vantagens e limitações do seu uso. É conclusivo que este método, através da construção de cadeias A-C-V, proporciona elementos de estudo que permitem a visualização de hierarquia de valores produzida pelos consumidores, função dos critérios de escolha destes durante e após um processo de compra. A aplicabilidade desta metodologia na perspectiva do valor para o cliente, permite a utilização dos seus resultados num conjunto de áreas específicas do marketing, das quais destacamos a segmentação e análise de mercado, a avaliação do posicionamento de produtos e marcas, a avaliação da publicidade e o desenvolvimento de estratégias de comunicação. ABSTRACT: The customer value construct is the one that best explains the consumer behavior, since its purpose is to understand how consumers translate the attributes and consequences of the use of a product in relevant personal values. The laddering methodology, which is based on the theory of means-end chains, is a theoretical element that is considered consistent for establish the relationship between attributes and consumer values. This thesis attempts to demonstrate the feasibility of the laddering methodology in studies about the value for the consumer, knowing what are the advantages and limitations of its use. It is conclusive that this method, by building chains A-C-V, provides elements of study that allows the visualization of the values hierarchy produced by consumers, according to the criteria of their choice during and after a purchase process. The applicability of this methodology from the perspective of customer value, allows the use of their results in a number of specific areas of marketing, which we emphasize the segmentation and market analysis, evaluation of product and branding positioning, evaluation of advertising and development of communication strategies.

Nível hemoglobínico em escolares da capital de São Paulo, Brasil

Com o objetivo de obter dados para avaliação do estado nutritivo dos escolares, o Serviço de Saúde Escolar da Secretaria da Educação do Estado de São Paulo, Brasil, realizou um inquérito laboratorial, usando como parâmetro a determinação da taxa hemoglobínica numa amostra de 20% dos 2.440 alunos do Grupo Escolar "Leonor Quadros", localizado em um bairro periférico da cidade de São Paulo. O método de exame utilizado constituiu na dosagem fotocolorimétrica da hemoglobina, empregando-se para isto um fotocolorímetro fabricado pelo Laboratório Ames do Brasil S/A. A taxa hemoglobínica média encontrada foi de 13,0 g%, sendo a média masculina de 13,09 g% e a feminina de 12,99g%. As taxas mínimas e máximas foram de 7,5 g% e 17,09 g%. Para melhor ordenação dos resultados, e de acordo com o nível hemoglobínico obtido, os escolares foram divididos em três grupos: o 1.° compreendendo escolares com nível hemoglobínico até 10,99 g%; o 2.º, entre 11,0 g% e 12,99g%, e o 3.°, acima de 13,0%. No primeiro grupo foram encontrados 2,3% dos alunos; no segundo, 36,2%, e no terceiro, 61,4%, verificando-se que 96% dos escolares apresentam nível hemoglobínico na faixa de 11,0 g% e mais. À vista dos resultados obtidos, considerou-se de razoável para bom o estado nutritivo dos escolares examinados.

Muscle strength, balance and functional independence in persons with stroke

Cerebral vascular disease is one of the main causes of morbidity, disability and mortality in developed countries. Problems with movement control are frequent after stroke. Lower limb weakness and impaired balance are common problems that are related with the risk of falls and are likely to interfere with the ability to perform daily life activities. Physiotherapy intervention usually starts early after stroke and addresses impairments related to movement and posture in order to improve motor recovery and restore function. Purpose: to investigate the relationship between knee muscle strength, balance and functional independence within the first month after stroke.

Shareholder wealth creation in response to announcements of acquisitions of unlisted firms: Evidence from Spain

We investigate shareholder value creation of Spanish listed firms in response to announcements of acquisitions of unlisted companies and compare this experience to the purchase of listed firms over the period 1991–2006. Similar to foreign markets, acquirers of listed targets earn insignificant average abnormal returns, whereas acquirers of unlisted targets gain significant positive average abnormal returns. When we relate these results to company and transaction characteristics our findings diverge from those reported in the literature for other foreign markets, as our evidence suggests that the listing status effect is mainly associated with the fact that unlisted firms tend to be smaller and lesser–known firms, and thus suffer from a lack of competition in the market for corporate control. Consequently, the payment of lower premiums and the possibility of diversifying shareholders’ portfolios lead to unlisted firm acquisitions being viewed as value–orientated transactions.

Conceptual model for decomposing the value for the customer

Value has been defined in different theoretical contexts as need, desire, interest, standard /criteria, beliefs, attitudes, and preferences. The creation of value is key to any business, and any business activity is about exchanging some tangible and/or intangible good or service and having its value accepted and rewarded by customers or clients, either inside the enterprise or collaborative network or outside. “Perhaps surprising then is that firms often do not know how to define value, or how to measure it” (Anderson and Narus, 1998 cited by [1]). Woodruff echoed that we need “richer customer value theory” for providing an “important tool for locking onto the critical things that managers need to know”. In addition, he emphasized, “we need customer value theory that delves deeply into customer’s world of product use in their situations” [2]. In this sense, we proposed and validated a novel “Conceptual Model for Decomposing the Value for the Customer”. To this end, we were aware that time has a direct impact on customer perceived value, and the suppliers’ and customers’ perceptions change from the pre-purchase to the post-purchase phases, causing some uncertainty and doubts.We wanted to break down value into all its components, as well as every built and used assets (both endogenous and/or exogenous perspectives). This component analysis was then transposed into a mathematical formulation using the Fuzzy Analytic Hierarchy Process (AHP), so that the uncertainty and vagueness of value perceptions could be embedded in this model that relates used and built assets in the tangible and intangible deliverable exchange among the involved parties, with their actual value perceptions.

Particle swarm optimization based approaches to vehicle-to-grid scheduling

This paper addresses the problem of energy resources management using modern metaheuristics approaches, namely Particle Swarm Optimization (PSO), New Particle Swarm Optimization (NPSO) and Evolutionary Particle Swarm Optimization (EPSO). The addressed problem in this research paper is intended for aggregators’ use operating in a smart grid context, dealing with Distributed Generation (DG), and gridable vehicles intelligently managed on a multi-period basis according to its users’ profiles and requirements. The aggregator can also purchase additional energy from external suppliers. The paper includes a case study considering a 30 kV distribution network with one substation, 180 buses and 90 load points. The distribution network in the case study considers intense penetration of DG, including 116 units from several technologies, and one external supplier. A scenario of 6000 EVs for the given network is simulated during 24 periods, corresponding to one day. The results of the application of the PSO approaches to this case study are discussed deep in the paper.

Intelligent energy resource management considering vehicle-to-grid: A simulated annealing approach

This paper proposes a simulated annealing (SA) approach to address energy resources management from the point of view of a virtual power player (VPP) operating in a smart grid. Distributed generation, demand response, and gridable vehicles are intelligently managed on a multiperiod basis according to V2G user´s profiles and requirements. Apart from using the aggregated resources, the VPP can also purchase additional energy from a set of external suppliers. The paper includes a case study for a 33 bus distribution network with 66 generators, 32 loads, and 1000 gridable vehicles. The results of the SA approach are compared with a methodology based on mixed-integer nonlinear programming. A variation of this method, using ac load flow, is also used and the results are compared with the SA solution using network simulation. The proposed SA approach proved to be able to obtain good solutions in low execution times, providing VPPs with suitable decision support for the management of a large number of distributed resources.

Research on using the decision tree method in order to select the best alternative for the pharmacies supply

Introduction / Aims: Adopting the important decisions represents a specific task of the manager. An efficient manager takes these decisions during a sistematic process with well-defined elements, each with a precise order. In the pharmaceutical practice and business, in the supply process of the pharmacies, there are situations when the medicine distributors offer a certain discount, but require payment in a shorter period of time. In these cases, the analysis of the offer can be made with the help of the decision tree method, which permits identifying the decision offering the best possible result in a given situation. The aims of the research have been the analysis of the product offers of many different suppliers and the establishing of the most advantageous ways of pharmacy supplying. Material / Methods: There have been studied the general product offers of the following medical stores: A&G Med, Farmanord, Farmexim, Mediplus, Montero and Relad. In the case of medicine offers including a discount, the decision tree method has been applied in order to select the most advantageous offers. The Decision Tree is a management method used in taking the right decisions and it is generally used when one needs to evaluate the decisions that involve a series of stages. The tree diagram is used in order to look for the most efficient means to attain a specific goal. The decision trees are the most probabilistic methods, useful when adopting risk taking decisions. Results: The results of the analysis on the tree diagrams have indicated the fact that purchasing medicines with discount (1%, 10%, 15%) and payment in a shorter time interval (120 days) is more profitable than purchasing without a discount and payment in a longer time interval (160 days). Discussion / Conclusion: Depending on the results of the tree diagram analysis, the pharmacies would purchase from the selected suppliers. The research has shown that the decision tree method represents a valuable work instrument in choosing the best ways for supplying pharmacies and it is very useful to the specialists from the pharmaceutical field, pharmaceutical management, to medicine suppliers, pharmacy practitioners from the community pharmacies and especially to pharmacy managers, chief – pharmacists.

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.
