Exporting a model of integrated disease management: A cross-case study analysis and application to Associação Protectora dos Diabéticos de Portugal

Although literature is lacking in the topic of internationalization of services, we manage to apply both the Uppsala model and the Eclectic Theory to the healthcare service. A cross-case study analysis with three international hospitals is done in order to define an internationalization pattern and conditions for a successful process. This is then applied to Associação Protectora dos Diabéticos de Portugal with the purpose of defining an internationalization strategy to the Association.

The economics of Vieira da Silva

This paper investigates the time valuation and the age valuation profile of art-works created by the Portuguese female painter Maria Helena Vieira da Silva. It uses data from records from her paintings auction sales between 1986 and 2014, taken from Artprice.com. The study explores three aspects regarding her artistic career: (1) estimation of Age-valuation profile, defining her creativity pattern and the age at which she produced her most valuable paintings; (2) estimation of time valuation profile, through a creation of an individual hedonic price index for Vieira da Silva; (3) internationalization phenomenon of the artist, investigating whether selling prices are primarily set in euros or in US dollar. The results suggest that Vieira da Silva peaked quite early in her career; her paintings prices are not very sensible to economic cycles and tends to slightly increase afterlife; the empirical results are not suggestive on which currency is the best predictor of her paintings’ price.

A responsabilidade da sociedade diretora com os credores da sociedade subordinada

The scope of the present study encompasses the liability of the directing company for the obligations of the subordinated company. Whereas the concept of directing company is comprised in the broader context of groups of companies and, consequently, in the comprehensive framework of the relationships established among such entities, this study starts by defining the notion of groups of companies, distinguishing it from related figures. It, then, moves on to analyse the legal regime applicable to groups of companies in some legal systems deemed significant, notably the American, European and German systems. Finally, this paper scrutinizes the provisions of article 501 of the Portuguese Companies Code (“Códigodas Sociedades Comerciais”), in particular its systematics and peculiarities, so as to ascertain which is the liability scheme 2 applicable to the directing or dominant company for the obligations of the subordinates or dominated company. Pursuant to no. 1 of article 501of the CSC, the directing company’s liability for such obligations exists provided these commitments are born before, during and until such time the subordination contract is terminated. The liability of the directing or dominant company for the debts of the subordinated or dominated company ceases as of the moment when the relationship between those two entities no longer exists, with immediate effect.

Simplified wind turbine models for wind energy integration into power systems

This paper analyses the boundaries of simplified wind turbine models used to represent the behavior of wind turbines in order to conduct power system stability studies. Based on experimental measurements, the response of recent simplified (also known as generic) wind turbine models that are currently being developed by the International Standard IEC 61400-27 is compared to complex detailed models elaborated by wind turbine manufacturers. This International Standard, whose Technical Committee was convened in October 2009, is focused on defining generic simulation models for both wind turbines (Part 1) and wind farms (Part 2). The results of this work provide an improved understanding of the usability of generic models for conducting power system simulations.

Malignancies in HIV/AIDS patients attending an outpatient clinic in Vitória, State of Espírito Santo, Brazil

INTRODUCTION: The present study investigated cancer prevalence and associated factors among HIV-infected individuals attending an AIDS outpatient clinic in Vitória, State of Espírito Santo, Brazil. METHODS: A sectional study was conducted among HIV infected adults attending an AIDS outpatient clinic in Vitória, State of Espírito Santo, Brazil. Demographic, epidemiological and clinical data were abstracted from medical records, including cancer diagnoses; nadir and current CD4 cell count, HIV viral load, time on antiretroviral treatment (ART), type of ART and smoking status. RESULTS: A total of 730 (91.3%) patients were included in the study. Median age was 44.0 [interquartile range (IQR): 35-50.3] years; median time since HIV diagnosis was 5.5 years (IQR: 2-10); 60% were male; and 59% were white. Thirty (4.1%) cases of cancer were identified of which 16 (53%) were AIDS defining cancers and 14 (47%) were non-AIDS defining malignancies. Patients diagnosed with cancer presented higher chance of being tobacco users [OR 2.2 (95% CI: 1.04-6.24)]; having nadir CD4 ≤200 cells/mm³ [OR 3.0 (95% CI: 1.19-7.81)] and higher lethality [OR 13,3 (95% CI: 4,57-38,72)]. CONCLUSIONS: These results corroborate the importance of screening for and prevention of non-AIDS defining cancers focus in HIV-infected population, as these cancers presented with similar frequency as AIDS defining cancers.

Evolution of coauthorship networks: worldwide scientific production on leishmaniasis

Introduction Collaboration is one of the defining features of contemporary scientific research, and it is particularly important with regard to neglected diseases that primarily affect developing countries. Methods The present study has identified publications on leishmaniasis in the Medline database from 1945 to 2010, analyzing them according to bibliometric indicators and statistics from social network analysis. Examining aspects such as scientific production, diachronic evolution, and collaboration and configuration of the research groups in the field, we have considered the different types of Leishmania studied and the institutional affiliation and nationality of the authors. Results Seven-hundred and thirty-five authors participate in 154 prominent research clusters or groups. Although the most predominant and consolidated collaborations are characterized by members from the same country studying the same type of Leishmania, there are also notable links between authors from different countries or who study different clinical strains of the disease. Brazil took the lead in this research, with numerous Brazilian researchers heading different clusters in the center of the collaboration network. Investigators from the USA, India, and European countries, such as France, Spain, the United Kingdom, and Italy, also stand out within the network. Conclusions Research should be fostered in countries such as Bangladesh, Nepal, Sudan, and Ethiopia, where there is a high prevalence of different forms of the disease but limited research development with reference authors integrated into the collaboration networks.

A Produção televisiva na era da mudança e da concorrência

Apesar do atual contexto de mudança resultante da crescente convergência dos média e da constante transformação tecnológica que as sociedades vivem, a televisão tem uma influência muito significativa na sociedade portuguesa e o entretenimento é um dos conteúdos com maior presença na vida dos espetadores. Assim, o relatório pretende analisar as mudanças que os mercados têm sofrido e compreender de que forma estas influenciam os hábitos de consumo dos públicos e a conquista dos mesmos. Para tal, o relatório incidirá sobre o novo programa da tarde da RTP1, o "Há Tarde". Refletindo sobre o que a Produção envolve, pretendo identificar e avaliar o porquê da criação de um novo programa e de que forma este se adaptou ao novo panorama audiovisual atual e, para além disso, compreender de que forma isso se reflete no seu sucesso.

Video metadata extraction in a videoMail system

Currently the world swiftly adapts to visual communication. Online services like YouTube and Vine show that video is no longer the domain of broadcast television only. Video is used for different purposes like entertainment, information, education or communication. The rapid growth of today’s video archives with sparsely available editorial data creates a big problem of its retrieval. The humans see a video like a complex interplay of cognitive concepts. As a result there is a need to build a bridge between numeric values and semantic concepts. This establishes a connection that will facilitate videos’ retrieval by humans. The critical aspect of this bridge is video annotation. The process could be done manually or automatically. Manual annotation is very tedious, subjective and expensive. Therefore automatic annotation is being actively studied. In this thesis we focus on the multimedia content automatic annotation. Namely the use of analysis techniques for information retrieval allowing to automatically extract metadata from video in a videomail system. Furthermore the identification of text, people, actions, spaces, objects, including animals and plants. Hence it will be possible to align multimedia content with the text presented in the email message and the creation of applications for semantic video database indexing and retrieving.

Agora Nós: a audiência e os programas televisivos do canal público

A televisão do século xx e da primeira década do século XXI não foi uma televisão do espectador. A neotelevisão veio acabar com a ligação unidireccional que a paleotelevisão mantinha com o telespectador, criando uma maior proximidade devido às semelhanças com o quotidiano do individuo. O talk-show, o género televisivo mais popular na América nos anos 90, é frequentemente a principal companhia e fonte de informação para milhares de espectadores. O talk-show alia informação ao entretenimento através do talk, com entrevistas entre convidado e apresentador intercaladas por momentos de humor e música, o show. O sucesso de um talk-show é observável pela audiência registada, uma vez que as emissões são feitas de acordo com o perfil do público que assiste televisão nesse determinado período. Em Portugal, o entretenimento representado pela ficção e pelos programas recreativos, ocupa uma grande parte da grelha de programação da televisão generalista. Na RTP, vários foram os talk-shows que serviram de modelo para outros programas pela forma peculiar e inovadora com que se apresentaram, como é o caso do Praça da Alegria. Em 2014, a renovação das manhãs da RTP foi assinalada pela estreia do Agora Nós, um talk-show com incidência nas histórias de vida do cidadão comum. Estas histórias tornam-se exemplos de vida para os espectadores, aproximando-os e identificando-os com o programa. O Agora Nós está inserido num canal de serviço público e, portanto, deve assegurar conteúdos variados, de referência e qualidade, com valorização cultural, económica e educacional que corresponda às necessidades e interesses do público.

The use of technology in Portuguese hospitals- The case of MRI

We study the determinants of MRI use across Portuguese NHS hospitals for patients belonging to specific DRGs. Using data on individual hospital admissions, we estimate a probit model including individual-, hospital-, time- and region-specific variables in order to explain the probability of a patient being sent for MRI. Results convey a tightening effect on the hospital’s budget constraint in the end of each year. Hospitals seem to account for regional characteristics when defining adoption patterns. Individual-specific variables are good predictors of MRI use. Measures taken by the Government only impact the short run. Finally, the gains from an MRI scan, as far as the probability of death is concerned, occur mainly for less severe patients.

A análise dos mecanismos é feita a partir dos vídeos disponíveis do programa, onde decorreu o estágio a que este relatório se refere, no período entre 22 de Setembro e 24 de Dezembro de 2014.

Do jogo de fortuna ou azar

Currently, gambling doesn’t have a strong social disapproval. However, the phenomenon of gambling raises several issues related to property protection, compulsive gambling, the youngest personality development, the State taxes and social development measures, which some authors believe to be the protected legal interest in the criminalization of illegal gambling exploitation. However, the authorization system, and because several of those interests, constitutionally protected, are also violated in the authorized gambling places, it appears that the legislator intended to define the legal interest as the order and public tranquility. The purpose of this study is to understand what is protected with the illegal gambling exploitation. This will involve defining the concept of exploitation and the concept of gambling. Still, we will try to know if there are situations without ethical and social resonance and what their consequences.

Migrant networks and migrant intentions to return

Social ties are potentially an important determinant of migrants’ intention to return to their home country, and yet this topic has not been addressed in the existing economics literature on international migration. This study examines the absolute and relative importance of migrant social networks both at destination and at origin. We base our research on experimental data from Batista and Narciso (2013)1. By defining networks according to different characteristics of their members and migrant return intentions with respect to three different time horizons, we are able to dissect the network effect into its components. After controlling for unobserved heterogeneity and reverse causality biases we find that network at home seems to be the most important determinant of the migrant’s intention to return home within five and ten years.

Protecção de crianças e jovens em Portugal

The causes of children rights and youth rights have been the focus of our attention. The ideals of freedom and justice accompany us in our daily lives and, as such, this thesis aims to study the questions of major importance in the field of children and youth protection in Portugal which deserve deep and serious reflection. We shall start with a brief theoretical framework of the evolution of the rights of children and youth in Portugal, defining some concepts. This will be followed by an analysis of all relevant Portuguese legislation, which will set out its fields of application, measures, objectives and underlying principles. There are multiple reasons to raise awareness to the importance of the topics that will be treated and to the necessity and urgency of thinking about an effective promotion and protection of children and youth in Portugal. Keywords: children,

Comparative analysis of Spanish Banks’ Standalone credit profile

The paper studies the relationship between four differently rated bank’s financial profile and their standalone credit rating issued by Moody’s. The comparative analysis shows an example that despite their pricing power and geographical coverage, larger banks do not necessarily have better credit ratings. Instead, business model and risk appetite seem to be the defining factors of banks’ vulnerability to shocks, such as the Spanish real estate crisis. The risk-return relationship is also identified in the banks’ fundamentals meaning that while expansionary strategy in riskier asset classes enhances margins, it also potentially distorts the credit risk profile.
