GesRetail : software de gestión integral

El proyecto surge con el fin de crear una aplicación que responda a las necesidades de gestión y control de las actividades que se desarrollan en empresas minoristas dedicadas al sector de la electrónica de consumo. Este tipo de establecimientos aunque están muy especializados y proporcionan un trato excelente al público, suelen tener deficiencias técnicas a la hora de gestionar y controlar su negocio. Muchos de ellos carecen de programas informáticos adaptados a sus necesidades, e incluso en algún caso no disponen de ninguno por el alto coste que les supone. Dicho software tiene dos objetivos: por un lado atender las necesidades de este sector y por otro que el desembolso de la adquisición e implantación del mismo sea asequible. Para conseguir este último objetivo se utilizará software libre.

Behavioral aspects of investment fund's markets: are good managers lucky or skilled?

It is generally accepted that financial markets are efficient in the long run a lthough there may be some deviations in the short run. It is also accepted that a good portfolio manager is the one who beats the market persistently along time, this type of manager could not exist if markets were perfectly efficient According to this in a pure efficient market we should find that managers know that they can not beat the market so they would undertake only pure passive management strategies. Assuming a certain degree of inefficiency in the short run, a market may show some managers who tr y to beat the market by undertaking active strategies. From Fama’s efficient markets theory we can state that these active managers may beat the market occasionally although they will not be able to enhance significantly their performance in the long run. On the other hand, in an inefficient market it would be expected to find a higher level of activity related with the higher probability of beating the market. In this paper we follow two objectives: first, we set a basis to analyse the level of efficiency in an asset invest- ment funds market by measuring performance, strategies activity and it’s persistence for a certain group of funds during the period of study. Second, we analyse individual performance persistence in order to determine the existence of skilled managers. The CAPM model is taken as theoretical background and the use of the Sharpe’s ratio as a suitable performance measure in a limited information environment leads to a group performance measurement proposal. The empiri- cal study takes quarterly data from 1999-2007 period, for the whole population of the Spanish asset investment funds market, provided by the CNMV (Comisión Nacional del Mercado de Valores). This period of study has been chosen to ensure a wide enough range of efficient market observation so it would allow us to set a proper basis to compare with the following period. As a result we develop a model that allows us to measure efficiency in a given asset mutual funds market, based on the level of strategy’s activity undertaken by managers. We also observe persistence in individual performance for a certain group of funds

Debt enforcement and relational contracting

We examine how third-party debt enforcement affects the emergence and performance ofrelational contracts in credit markets. We implement an experiment with finitely repeatedcredit relationships in which borrowers can default. In the weak enforcement treatmentdefaulting borrowers can keep their funds invested. In the strong enforcement treatmentdefaulting borrowers have to liquidate their investment. Under weak enforcement fewerrelationships emerge in which loans are extended and repaid. When such relationships doemerge they exhibit a lower credit volume than under strong enforcement. These findingssuggest that relational contracting in credit markets requires a minimum standard of thirdpartydebt enforcement.

A sexualidade segundo Michel Foucault: uma contribuição para a enfermagem

A autora desenvolve uma reflexão sobre a concepção de Foucault em relação ao "dispositivo da sexualidade" apresentada no livro "Microfísica do Poder". Busca resgatar, através dessa literatura clássica, uma visão histórico-social da prática de enfermagem, tendo em vista a racionalidade atual que deprecia a afetividade nas relações pessoais ao supervalorizar a virilidade masculina, tornando o prazer um bem de consumo e um fim em si mesmo.

Planificació pel canvi de plataforma del CPD cap a l'e-administració

Estudi de millora i ampliació d'un prototip per a la gestió comercial de PIMES

El projecte consta bàsicament en la millora i ampliació d'un projecte anterior que es trobava en una primera versió d'implementació d'una part d'un CRM. Seguint amb la filosofia de la versió anterior, continua sent una aplicació de gestió per a PIMES. On s'hi ha afegit la idea de món globalitzat. Aquesta idea, ens comporta pensar en que una empresa encara que sigui petita, pot fer gestions arreu del món. Es aquest "gestions arreu del món" que ens comporta acceptar idees com la de tractar amb clients que parlin idiomes diferents al nostrem enviar informació a través del correu electrònic pel temps que comportaria fer-ho pel correu ordinari, o fins i tot el tipus de moneda que utilitzin els clients.

Crianças em situação de rua falam sobre os abrigos

O artigo versa sobre relatos de crianças de/na rua quanto à experiência de viver em abrigos. Compreende parte de uma investigação, cujo objetivo consistiu em apreender como crianças em situação de rua, na cidade de São Paulo, representam sua trajetória de vida. Os dados, coletados em entrevistas individuais, foram organizados segundo o método de Análise de Conteúdo e preceitos da teoria da Representação Social. As categorias destacadas do discurso transcrito foram agrupadas em experiências significativas para as crianças, entre as quais "os abrigos". A análise dessa categoria evidenciou que a falta de um atendimento mais personalizado e afetuoso nos abrigos contribui para que as crianças optem por se manterem nas ruas.

Stockholder conflicts and dividends

Conflicts of interest between majority and minority stockholders affect a large proportion of firms in any economy, but has received little attention in the empirical literature. We examine the link between the potential for such conflicts and the firm's payout policy on a large sample of Norwegian private firms with controlling stockholders and detailed ownership data. Our evidence shows that the stronger the potential conflict between the stockholders, the higher the proportion of earnings paid out as dividends. This tendency to reduce stockholder conflicts by dividend payout is more pronounced when the minority is diffuse and when a family's majority block is held by a single family member. We also find evidence that a minority-friendly payout policy is associated with higher future minority investment in the firm. These results are consistent with the notion that potential agency costs of ownership are mitigated by dividend policy when the majority stockholder benefits from not exploiting the minority.

An Analysis of black-box optimization problems in reinsurance: evolutionary-based approaches

Black-box optimization problems (BBOP) are de ned as those optimization problems in which the objective function does not have an algebraic expression, but it is the output of a system (usually a computer program). This paper is focussed on BBOPs that arise in the eld of insurance, and more speci cally in reinsurance problems. In this area, the complexity of the models and assumptions considered to de ne the reinsurance rules and conditions produces hard black-box optimization problems, that must be solved in order to obtain the optimal output of the reinsurance. The application of traditional optimization approaches is not possible in BBOP, so new computational paradigms must be applied to solve these problems. In this paper we show the performance of two evolutionary-based techniques (Evolutionary Programming and Particle Swarm Optimization). We provide an analysis in three BBOP in reinsurance, where the evolutionary-based approaches exhibit an excellent behaviour, nding the optimal solution within a fraction of the computational cost used by inspection or enumeration methods.
