Reabilitação no Acidente Vascular Cerebral: do Hospital à Comunidade

The field of action for rehabilitation is that of making use of the patient's maximum functional capacity with the purpose of adapting to life in relation to the environment. Rehabilitation must commence immediately, although it may be in different forms from the acute phase to sequelae. It is considered appropriate to call the physiatrist as soon as the neurologic condition has stabilised. A list is made of the measures to be taken for rehabilitation in the acute phase and sequelae, and the composition of the rehabilitation team is described. In what concerns location, where to rehabilitate the patient? The group of ambulatory patients should have their rehabilitation as outpatients. Our experience with house calls is briefly described. The group of patients who cannot walk, those that present an eminently motor condition, with the possibility of being able to walk, should be with their families, with transport provided to health and rehabilitation centres. The second group, with the capacity of walking within a reasonable time, especially if with multiple associated problems such as impaired communication, should be hospitalised in a rehabilitation department. The third group consists of severely handicapped patients, for whom a solution must be found that provides life with a minimum of dignity in centres or homes. From among the measures to be introduced, we point out following: acquisition of transport for patients who must travel, as outpatients, to the department; providing family doctors with complete freedom to refer their patients to rehabilitation centres.

Reclamações : a sua importância nas unidades de saúde privadas : um estudo de caso

RESUMO - O sector privado da saúde tem registado um forte crescimento em Portugal. Como principais factores apontam-se a crescente preocupação dos indivíduos com a sua saúde, o aumento do poder de compra, a possibilidade de exercer a escolha do seu prestador de cuidados, o maior conforto proporcionado no consumo de cuidados de saúde e o acesso mais rápido a esses cuidados (por comparação com o serviço público). Em consequência desses factores, existe por parte da instituição privada de saúde a necessidade de apostar num sistema de gestão de reclamações capaz de dar uma resposta rápida às necessidades, expectativas e preferências do indivíduo enquanto doente e cliente. Nesse âmbito, desenvolveu-se um estudo de investigação qualitativo. Recorreu-se à realização de entrevistas semi-estruturadas cujo tratamento foi submetido à técnica de análise de conteúdo. Procurou-se perceber o que pensam os responsáveis pela gestão e tratamento das reclamações acerca da importância do circuito de reclamação, da utilização das reclamações como uma ferramenta de gestão e qual o seu impacto na estratégia da instituição privada de saúde. Dos resultados obtidos, verifica-se que, à data, dá-se ainda pouca relevância a este tema, observando-se falhas a nível do circuito de reclamação. Hoje, a reclamação é ainda pouco utilizada e perspectivada como uma ferramenta de gestão. O seu impacto na estratégia da instituição, apesar de ser relevante, tem potencial para ser melhorado, na perspectiva da learning organization. Seria importante articular as estratégias de qualidade, com a formação dos profissionais na área da reclamação, implementação ou melhoria dos instrumentos utilizados nas respostas ao cliente e à entidade reguladora do sector, bem como com o redesenho do circuito do sistema de informação nesta área.

Search and bargaining in large markets with homogeneous traders

We study pair-wise decentralized trade in dynamic markets with homogeneous, non-atomic, buyers and sellers that wish to exchange one unit. Pairs of traders are randomly matched and bargaining a price under rules that offer the freedom to quit the match at any time. Market equilbria, prices and trades over time, are characterized. The asymptotic behavior of prices and trades as frictions (search costs and impatience) vanish, and the conditions for (non) convergence to walrasian prices are explored. As a side product of independent interest, we present a self-contained theory of non-cooperative bargaining with two-sided, time-varying, outside options.

A geometric mechanism of diffusion: Rigorous verification in a priori unstable Hamiltonian systems

In this paper we consider a representative a priori unstable Hamiltonian system with 2+1/2 degrees of freedom, to which we apply the geometric mechanism for diffusion introduced in the paper Delshams et al., Mem.Amer.Math. Soc. 2006, and generalized in Delshams and Huguet, Nonlinearity 2009, and provide explicit, concrete and easily verifiable conditions for the existence of diffusing orbits. The simplification of the hypotheses allows us to perform explicitly the computations along the proof, which contribute to present in an easily understandable way the geometric mechanism of diffusion. In particular, we fully describe the construction of the scattering map and the combination of two types of dynamics on a normally hyperbolic invariant manifold.

Girls’ Education: Keeping Girls in School. ( A Literature Review with Implications for Girls’ School Attendence in Cape Verde)

Education plays a very important role in society’s development in order to promote good citizenship and individual rights and freedom. To this end, it is fundamental that girls be included in the education process. Inmost developed and developing countries, theoretically, both males and females have access to education. Cape Verde is no exception; however, the reality is that even in Cape Verde, promoting girls’ education and creating conditions to motivate girls to stay in school remains a challenge. Whereas girls have access to education many girls drop out for gender-related reasons. This paper will investigate girls’ education initiatives in general, and Cape Verde specific to offer recommendations and strategies to keep girls in school.

A century of global equity market correlations

In this paper, we use a unique long-run dataset of regulatory constraints on capital account openness to explain stock market correlations. Since stock returns themselves are highly volatile, any examination of what drives correlations needs to focus on long runs of data. This is particularly true since some of the short-term changes in co-movements appear to reverse themselves (Delroy Hunter 2005). We argue that changes in the co-movement of indices have not been random. Rather, they are mainly driven by greater freedom to move funds from one country to another. In related work, Geert Bekaert and Campbell Harvey (2000) show that equity correlations increase after liberalization of capital markets, using a number of case studies from emerging countries. We examine this pattern systematically for the last century, and find it to be most pronounced in the recent past. We compare the importance of capital account openness with one main alternative explanation, the growing synchronization of economic fundamentals. We conclude that greater openness has been the single most important cause of growing correlations during the last quarter of a century, though increasingly correlated economic fundamentals also matter. In the conclusion, we offer some thoughts on why the effects of greater openness appear to be so much stronger today than they were during the last era of globalization before 1914.

Multiple prisoner's dilemma games with (out) an outside option: An experimental study

Experiments in which subjects play simultaneously several finite prisoner's dilemma supergames with and without an outside optionreveal that: (i) subjects use probabilistic start and endeffect behaviour, (ii) the freedom to choose whether to play the prisoner's dilemma game enhances cooperation, (iii) if the payoff for simultaneous defection is negative, subjects' tendency to avoid losses leads them to cooperate; while this tendency makes them stick to mutual defection if its payoff is positive.

Dyadic pulsations as a signature of sustainability in correspondence networks

In this paper, we introduce the concept of dyadic pulsations as a measure of sustainability in online discussion groups. Dyadic pulsations correspond to new communication exchanges occurring between two participants in a discussion group. A group that continuously integrates new participants in the on-going conversation is characterized by a steady dyadic pulsation rhythm. On the contrary, groups that either pursue close conversation or unilateral communication have no or very little dyadic pulsations. We show on two examples taken from Usenet discussion groups, that dyadic pulsations permit to anticipate future bursts in response delay time which are signs of group discussion collapses. We discuss ways of making this measure resilient to spam and other common algorithmic production that pollutes real discussions

Estudi i implantació de programari lliure

RESUM Actualment la majoria de nosaltres sabem de l’existència de molts programes lliures, però hem tenir clar que lliure no vol dir sempre programa gratuït. Tot i que a vegades sí que pot ser-ho, es té en compte molt més que això: és una manera de pensar i entendre el programari i al llarg dels anys ha generat tot un moviment social. Considerem que un programa lliure és aquell que garanteix als usuaris la llibertat per executar, copiar, distribuir, estudiar, canviar i millorar el codi programat, com molt bé defineixen les seves llibertats bàsiques. El programari lliure el podem trobar funcionant en ordinadors personals, escoles, empreses diverses, administracions, etc. ja que la majoria de programes que utilitzen actualment, com hem vist, tenen el seu equivalent en lliure. El fet de si és viable que una empresa es passi a programari lliure, depèn ben bé del seu entorn, ja que en funció d’aquest li serà més o menys fàcil la migració. La finalitat d’aquest projecte és, primer de tot, fer un ampli estudi del món del programari lliure i del seu moviment social. S’ha fet una recerca de diferents aspectes dins del programari lliure per conèixer-lo a fons i després s’ha proposat una possible implantació d’aquest en un usuari domèstic i en una administració pública, tenint en compte tots els aspectes vistos en l’estudi, valorant si totes les idees que defensa i els beneficis que aporta són aplicables i viables en qualsevol persona i àmbit i el perquè. Com a conclusió principal en destacaria que tot i que el programa lliure disposa d’una ideologia que agrada i té uns programes tècnicament perfectes (sense que això sigui el seu objectiu principal), penso que encara hi ha molt camí per recórrer quant a una migració en grans entorns, ja que per exemple en un ajuntament una migració total és encara difícil (tot i que no impossible perquè n’hi ha que s’hi han migrat). A l’apartat d’annexos s’hi inclou un glossari amb un seguit de terminologies amb paraules que no tothom pot saber i s’ha cregut oportú incloure-les en aquest apartat. La primera vegada que apareix alguna d’aquestes paraules la podem trobar senyalitzada amb un *.

A virtual exhibition of open source software for libraries

Frequently the choice of a library management program is conditioned by social, economic and/or political factors that result in the selection of a system that is not altogether suitable for the library’s needs, characteristics and functions. Open source software is quickly becoming a preferred solution, owing to the freedom to copy, modify and distribute it and the freedom from contracts, as well as for greater opportunities for interoperability with other applications. These new trends regarding open source software in libraries are also reflected in LIS studies, as evidenced by the different courses addressing automated programs, repositorymanagement, including the Linux/GNU operating system, among others. The combination of the needs of the centres and the new trends for open source software is the focus of a virtual laboratory for the use of open source software for library applications. It was the result of a project, whose aim was to make a useful contribution to the library community, that was carried out by a group of professors of the School of Library and Information Science of the University of Barcelona, together with a group of students, members of a Working Group on Open Source Software for Information Professionals, of the Professional Library Association of Catalonia.

La obligatoriedad de la mediación derivada de la voluntad de las partes: las cláusulas de mediación

[spa] La voluntariedad constituye el presupuesto de cualquier análisis sobre la mediación. De entre sus diversas manifestaciones, destacan la libertad de acogerse al procedimiento y la posibilidad de desistir del mismo en cualquier momento. Sin embargo, en relación con su primera manifestación ―libertad de acogerse a la mediación―, el principio de voluntariedad parece admitir ciertas modulaciones, debidas, por una parte, a la exigencia legal, en algunos casos, del uso de la mediación como condición de procedibilidad ante los tribunales (mandatory mediation) y, por otra, a la discutida admisibilidad de las llamadas"cláusulas de mediación". El estudio se centra en estas últimas. En particular, se analiza el debate que éstas han generado, su eficacia ―tanto ordinaria (derivada de su cumplimiento) como extraordinaria (consecuencia de su incumplimiento)― y la cuestión de sus posibles contenidos.

Managing an intellectual property right portfolio in the software industry

Tutkimuksen tavoitteena oli määrittää etuja, joita huolellinen immateriaali-oikeussalkun hallinnointi ohjelmistoalalla luo yritykselle. Tutkimusaineisto on kerätty haastattelemalla eri asemissa olevia ihmisiä kolmesta suomalaisesta ohjelmistoalan tuote- ja palveluyrityksestä. Tutkimuksesta käy ilmi, että ohjelmistoyritysten immateriaalioikeussalkut koostuvat liikesalaisuuksista, tekijänoikeudesta, tavaramerkeistä, verkkotunnuksista ja muutamista patenteista. Kiinnostus patentteihin ohjelmistoalalla on kasvanut erityisesti niiden tuoman tekijänoikeutta vahvemman suojan takia. Tällä hetkellä Euroopassa suhtautuminen ohjelmistopatentteihin on kuitenkin vielä käymistilassa. Jos ohjelmistopatentit hyväksytään, immateriaalioikeussalkun strateginen merkitys kasvaa. Tällöin salkunn hallinnointi tukee yrityksen tavoitteita - esimerkiksi oman toimintavapauden turvaamista - avustaen hakemus-prosessissa, tarkkaillen markkinoita sekä arvioiden yrityksen oman immateriaalioikeussalkun erilaisia hyväksikäyttömahdollisuuksia.
