How to monitor and improve Unilever JM Supply Chain processes to become the best of Portugal’s sector in 2015?

Unilever Jerónimo Martins is a Portuguese joint-venture leading firm in what concerns the supply chain industry of fast-moving consumer goods in Portugal. The scope of analysis of this Work Project is focusing on Unilever-JM operations and services in the Portuguese market regarding quality, efficiency and effectiveness over B2B customers. It will be analysed the possibility of development and implementation of a performance measurement system, Tableau de Bord, which will be crucial for the identification of potential opportunities of improvement with impact in the supply chain processes. This will be completed through the establishment of KPI’s to monitor and manage periodically logistics, planning and customer service processes’ performance, which are the ones where the bottlenecks are impacting more in the supply chain. In this work project the nexus causality for the problems will also be discussed and some recommendations will be prepared to tackle the inefficiencies found through the monitoring of the previous core processes, in order to improve efficacy and quality service of the supply chain.

Spinoffs and other entrants: Evidence from Portugal

This thesis studies the prevalence and survival of spinoff entrants in Portugal from 1987 to 2008. Information on worker flows is used to identify them at a population level, providing evidence on other operations such as mergers and acquisitions. We show that the number of spinoffs has been increasing at a higher rate than other entrants of comparable size. Studying the determinants of their exit suggests that the most important predictor is whether the spinoff was motivated by the failure of the parent firm. The effect of industry specific knowledge and previous experience of the founders from working together in the parent firm is seemingly negligible, with only weak evidence supporting the latter.

Produção de electricidade em Portugal

In the present work we intend to do an analysis of the production of electricity in special regime in Portugal. We will focus in particular in the remuneration system through the feed-in tariffs. First, we will excurse throughout different legal diplomas that regulated the special regime in Portugal, exploring which guarantees were conferred to electricity generators throughout the years. We intend to also evaluate how the producers remunerative rights were (or not) protected in the various legislative changes. In the second part of the dissertation we will examine whether the feed-in tariffs may be considered as State aid. Due to the inclusion of the subject in EU Law, we will analyze EU regulation and case law to support our position about the Portuguese regime. Finally, and to the extent that the production of electricity in special regime has undergone several changes to its remunerative regime in the last few years, we propose to analyze more carefully the amendments in question. We will scrutinize the reasons that based the amendments in question, which are mainly based on the economic crisis suffered by the country. We will also examine how those changes may jeopardize the remunerative rights of the producers.

Empirically testing the dimensions of consumer trust in e-commerce

In the fields of marketing and general management, many are the contributions of literature relating trust and e‐commerce. Trust is perceived as an issue that concerns the consumers’ intention to purchase. As so, in this research, a path model is empirically tested in order to develop solutions for Internet vendors on how to deal with consumers and increase their trust. The path model measures how the dimensions of trust, named as competence, integrity and benevolence positively influence the overall trust of the consumers and at the same time how the sources of trust – consumer characteristics, firm characteristics, website infrastructure and interactions influence those dimensions. The data used to test the model was collected in Portugal, through 365 valid cases. Findings revealed that consumers, which have high level of overall trust, are more likely to intent to purchase online.

E-loyalty in e-commerce: A study at GIRISSIMA.COM

Few studies have been conducted on causal antecedents for electronic loyalty regarding the online fashion industry. In Portugal there is no systematic empirical research in this area. This study aims to examine e-satisfaction and e-trust that potentially impact eloyalty. It also examines the impact of price, website design and selection of brands. A research study was performed at GIRISSIMA.COM and survey responses were 77. The findings show that e-satisfaction is the main driver of e-loyalty. E-trust, website design and price affect positively e-loyalty. Additionally, selection of brands was proved to impact e-loyalty through e-satisfaction and e-trust.

Why and how projects in organizations differ? The example of Portuguese profit and non-profit organizations

This research has as a goal to give an overview of what Project Management is in Portugal. The purpose is not to focus on a small picture, but to understand the broad concept and perception of Project Management in Portugal in two very important sectors: Profit- and Non-Profit Sector. Both Profit- and Non-Profit project managers have been interviewed, giving an insight of how different projects are in both sectors and why. This paper will be especially helpful comparing the Project Management maturity of Portugal to other countries regarding these two different point of views.

NAV Portugal's performance within the single European Sky Initiative

NAV Portugal is the Air Navigation Service Provider in Portugal, providing air traffic control services in the airspace under the country’s responsibility. Recently, the company has been included in an initiative launched by the European Commission, called the Single European Sky. This aims for a unification of the European airspace, improving it in four main pillars: safety, capacity, environment, and cost-efficiency. To each of them, Key Performance Indicators need to be computed and monitored, all having pre-defined targets. The presented work project will be analyzing how NAV Portugal is doing in the pillar of capacity, proving suggestions if needed.

Leadership in Angola and Mozambique: How Portuguese leaders overcome the human resources challenge and contribute to organizational success

This Work Project presents human resources as one of the major challenges that Portuguese leaders meet in Angola and Mozambique. The main goal is to understand the role of leaders in translating this challenge into benefits for their own business and the African society. To conduct this study 13 leaders who work in Portugal and Africa were interviewed. Then, a framework was constructed based on the two ways these leaders recognize the importance of their employees for sustainable growth – financial incentives or/and personal development. The main conclusion here is that individually, incentives and personal development are not effective methods. Because of this, an employee empowerment process is proposed that encloses both, along with the leaders’ personal qualities needed to implement that “ideal” process.

Study of glycosidic changes in lung cancer: potential effectors in hematogenous metastasis

RESUMO: O cancro do pulmão (LC), uma das principais causas de mortalidade relacionada com cancro em Portugal, pode levar à formação de metástases hematogénicas. A adesão das células tumorais ao endotélio é considerada um dos passos fundamentais envolvidos na metástase. Em células sanguíneas, esta adesão é mediada por ligandos de E-selectina (E-SL), glicoproteínas ou glicolípidos decorados principalmente com sialyl-Lewis x (sLex) e sialyl-Lewis a (sLea). Tem sido descrito a expressão destes antigénios em LC, contudo o seu papel funcional em permitir a adesão das células de LC ao endotélio é ainda pouco compreendido. Foram analisadas amostras emparelhadas normais e tumorais de pacientes com cancro de pulmão de não-pequenas células (NSCLC) e três linhas celulares de LC. Immunoblotting assays com anti-sLex/sLea e molécula quimérica de E-selectina demonstraram que tecidos tumorais de LC sobreexpressam significativamente E-SL e resultados de citometria de fluxo demonstraram uma expressão elevada de E-SL nas linhas celulares. Para compreender o mecanismo da sobreexpressão de E-SL em tecidos tumorais e linhas celulares de LC, foi analisada a expressão de genes envolvidos na biossíntese de E-SL, nomeadamente FUT3, FUT4, FUT6, FUT7, ST3GAL3, ST3GAL4, ST3GAL6, β4GALT1, GCNT1 e GALNT3. Observou-se a sobreexpressão das fucosiltransferases FUT3, FUT6 e FUT7 em tecidos tumorais de LC e FUT3 em linhas celulares de LC, sendo que neste último, esta expressão é correlacionada com um aumento da adesão das células de LC às selectinas endoteliais. Foi observado que uma baixa expressão de FUT4 em tecidos tumorais está associada com estadios menos avançados de NSCLC. Foram analisadas ainda proteínas decoradas com sLex/sLea, tendo-se identificado como E-SL o antigénio carcinoembrionário em NSCLC. Em resumo, esta tese contribuiu para uma melhor compreensão das alterações glicosídicas e moléculas que podem influenciar a progressão tumoral do LC, podendo permitir identificar futuramente novos biomarcadores de diagnóstico/prognóstico e potenciais alvos terapêuticos para o NSCLC.--------------------------ABSTRACT: Lung cancer (LC), one of the major causes of mortality related to cancer in Portugal, may lead to hematogenous metastasis. Adhesion of cancer cells to endothelium is considered one of the crucial steps involved in metastasis. In blood cells, this adhesion is initiated by endothelial selectin ligands (E-SL) that are glycoproteins or glycolipids decorated mostly with sialyl-Lewis x (sLex) and sialyl-Lewis a (sLea). While LC has been described as expressing these sialyl Lewis antigens, its functional role in allowing LC adhesion to endothelium is still poorly understood. We analyzed paired tumor and normal tissues samples from non-small cell lung cancer (NSCLC) patients and three LC cell lines. Immunoblotting assays with anti-sLex/sLea and E-selectin chimera demonstrated that LC tumor tissues significantly overexpress E-SL and flow cytometry results indicated that E-SL are also abundantly expressed in LC cell lines. To understand the mechanism behind the overexpression of E-SL in LC tissues and cell lines, we analyzed the expression of genes involved in its biosynthesis, namely FUT3, FUT4, FUT6, FUT7, ST3GAL3, ST3GAL4, ST3GAL6, β4GALT1, GCNT1 and GALNT3. It was observed the overexpression of fucosyltransferases FUT3, FUT6 and FUT7 in LC tumor tissues and FUT3 in LC cell lines, being this last one correlated with an increased reactivity of the LC cells to endothelial selectins. It was described that low expression of FUT4 in tumor tissues is correlated with early stages of NSCLC. We also analyzed scaffolds proteins of sLex/sLea and it was identified the carcinoembryonic antigen as an E-SL in NSCLC. In summary, this thesis contributed to a better understanding of the glycosidic changes and molecules that can influence tumor progression of LC, allowing identifying in the future new diagnosis/prognosis biomarkers and potential therapeutic targets for NSCLC.

Desigualdades sociais em saúde nos idosos : um retrato para Portugal

RESUMO - Contexto: As desigualdades sociais em saúde são uma questão central de justiça social. No contexto de forte envelhecimento populacional em Portugal, as desigualdades nos idosos representam um desafio crucial para o futuro, sobre as quais existe pouca evidência. Este estudo pretende investigar a existência de desigualdades socioeconómicas em saúde nos idosos, em Portugal. Metodologia: Foram utilizados os dados para Portugal, da quarta vaga do Survey of Health, Ageing and Retirement in Europe. O estudo engloba 2017 indivíduos com 50 ou mais anos. Foram utilizados quatro indicadores de saúde: problemas de saúde, saúde auto-reportada, doenças de longa duração e atividade limitada. Foi utilizado o nível de educação como indicador socioeconómico. As desigualdades socioeconómicas foram avaliadas através de regressões logísticas multivariadas. Resultados: Existem desigualdades socioeconómicas em saúde nos idosos favoráveis aos mais educados. Os indivíduos com menor educação estão em maior risco de reportar má saúde (OR=5,5); maior risco em ter problemas de saúde, existindo um gradiente social na Hipertensão Arterial (OR=2,4) e na Artrite (OR=7,0); maior risco de doenças de longa duração (OR=1,6) e maior risco de limitação nas atividades diárias (OR=5,1). As desigualdades socioeconómicas diminuem com a idade. Conclusão: De forma a melhorar a saúde e reduzir as desigualdades socioeconómicas em saúde nos idosos, os resultados apontam para a necessidade de implementar medidas no âmbito dos problemas de saúde em que existe um gradiente social, melhorar o nível de educação da população geral e implementar medidas de educação para a saúde, aumentando a literacia em saúde nos idosos mais jovens.

Mortalidade por neoplasias malignas na população residente próximo de minas de urânio em Portugal : Epidemiologia

RESUMO - Introdução: O encerramento das minas de urânio em Portugal tem suscitado preocupação no que respeita aos eventuais efeitos que as radiações emitidas e os agentes químicos presentes terão na saúde das populações. Para esclarecer a existência de tal efeito foi delineado um programa de investigação em que o presente estudo se enquadra. Sendo conhecido que as populações expostas a minas de urânio, nomeadamente os mineiros, têm risco acrescido de sofrer de neoplasias, especialmente de «neoplasias da traqueia, dos brônquios e do pulmão», foi este o grupo de neoplasias seleccionado para constituir a hipótese principal do estudo. Assim, o estudo pretendeu verificar se existe associação entre exposição a minas de urânio e suas escombreiras (especialmente à mina da Urgeiriça, no concelho de Nelas) e a mortalidade por alguns grupos de neoplasias malignas, nomeadamente as «neoplasias malignas da traqueia, dos brônquios e do pulmão». Material e métodos: Trata-se de um estudo «ecológico» em que se consideraram «expostos» os residentes no concelho de Nelas, bem como no conjunto de concelhos com minas de urânio, e «não expostos» os residentes nos restantes concelhos das NUTS Dão-Lafões e Beira Interior Norte e Serra da Estrela. A análise centrou-se no cálculo, para cada concelho ou grupo de concelhos, das razões padronizadas de mortalidade (RPM) por «neoplasias malignas da traqueia, dos brônquios e do pulmão», por «neoplasia maligna do estômago» e por «todas as neoplasias malignas » no período de vinte anos compreendido entre 1980 e 1999. Resultados: Tomando os dois sexos em conjunto, o concelho de Nelas teve a RPM mais elevada para as «neoplasias malignas da traqueia, dos brônquios e do pulmão» (RPM = 133; p = 0,003). Teve também o valor mais elevado no sexo masculino (RPM = 126, não significativo) e o segundo mais elevado no sexo feminino (RPM = 142, não significativo). A razão das RPM concelho de Nelas/concelhos limítrofes de Nelas foi 1,46, p = 0,002 (homens: 1,50 p = 0,003; mulheres: 1,27, não significativo). As razões das RPM concelho de Nelas/concelhos com minas (1,94, p = 0,001) e concelho de Nelas/concelhos sem minas (1,57, p = 0,001) foram claramente superiores a 1. Pelo contrário, as RPM por «neoplasia maligna do estômago » foram sobretudo elevadas nos concelhos da NUTS Beira Interior Norte, que inclui grande parte do distrito da Guarda, (Trancoso: 154, p = 0,000; Sabugal: 146, p = 0,000), embora se tenham observado valores elevados em alguns concelhos da NUTS Dão-Lafões (Vila Nova de Paiva: 154, p = 0,001). Saliente-se que os dois valores mais baixos ocorreram nos concelhos de Tábua (RPM = 57; p = 0,000) e de Nelas (RPM = 60; p = 0,000). Para o conjunto de «todas as neoplasias malignas» as RPM dos vários concelhos variaram entre 62 e 100 sem que a distribuição desses valores sugerisse qualquer associação positiva relevante. Discussão: Os resultados mostraram que a população do concelho de Nelas teve, no período estudado, um risco acrescido de morrer por «neoplasias malignas da traqueia, dos brônquios e do pulmão» quando comparado com a dos concelhos limítrofes e restantes concelhos das NUTS estudadas. A existência da mina da Urgeiriça e da sua escombreira é uma possível causa desse excesso de mortalidade. Ele poderá ter sido gerado, por um lado, através da existência de uma percentagem elevada de ex-mineiros, bem como, por outro lado, através de uma exposição ambiental geral, facto este que é sustentado pela ocorrência de excesso de mortalidade tanto em homens como em mulheres. O excesso de mortalidade por aquele grupo de neoplasias pode ainda ter origem noutras exposições cujo potencial papel é discutido.

O estatuto laboral do trabalhador estrangeiro em Portugal

After reading about the current legal regime regarding the foreign workers we realize the high relevance this area has, nevertheless the research about these issues has been lying somewhat stagnant in Portugal, particularly as it refers to non-EU citizens. At a time when we witness a progressive increase of the migratory movements we propose ourselves, in this study, to understand more clearly the current legal system in the matter of foreign worker rights, and, from a pragmatic point of view, to question some choices of the legislator in order to understand if these serves to the best protection of the rights and duties of the foreign workers and the new situations arising from this phenomenon, considering any system weaknesses. However, we realize that much remains to be done in this field, both in terms of true equal rights between nationals and foreigners, and either as what regards to an effort to harmonize these issues by the States, which tend to favor national sovereignty and its economic interests rather than protecting the fundamental rights of workers.

Molecular tools in the diagnostic and epidemiology of infections caused by members of Mycobacterium avium Complex

Mycobacterium avium Complex (MAC) comprises microorganisms that affect a wide range of animals including humans. The most relevant are Mycobacterium avium subspecies hominissuis (Mah) with a high impact on public health affecting mainly immunocompromised individuals and Mycobacterium avium subspecies paratuberculosis (Map) causing paratuberculosis in animals with a high economic impact worldwide. In this work, we characterized 28 human and 67 porcine Mah isolates and evaluated the relationship among them by Multiple-Locus Variable number tandem repeat Analysis (MLVA). We concluded that Mah population presented a high genetic diversity and no correlations were inferred based on geographical origin, host or biological sample. For the first time in Portugal Map strains, from asymptomatic bovine faecal samples were isolated highlighting the need of more reliable and rapid diagnostic methods for Map direct detection. Therefore, we developed an IS900 nested real time PCR with high sensitivity and specificity associated with optimized DNA extraction methodologies for faecal and milk samples. We detected 83% of 155 faecal samples from goats, cattle and sheep, and 26% of 98 milk samples from cattle, positive for Map IS900 nested real time PCR. A novel SNPs (single nucleotide polymorphisms) assay to Map characterization based on a Whole Genome Sequencing analysis was developed to elucidate the genetic relationship between strains. Based on sequential detection of 14 SNPs and on a decision tree we were able to differentiate 14 phylogenetic groups with a higher discriminatory power compared to other typing methods. A pigmented Map strain was isolated and characterized evidencing for the first time to our knowledge the existence of pigmented Type C strains. With this work, we intended to improve the ante mortem direct molecular detection of Map, to conscientiously aware for the existence of Map animal infections widespread in Portugal and to contribute to the improvement of Map and Mah epidemiological studies.

Fiscal dynamics and electoral behavior in the Eurozone

Abstract: The Stability Growth Pact and the 3% rule did not prevent countries from running large deficits. Countries in the EMU administrate fiscal policies differently, despite the existence of a common quantitative goal. The main focus of this work project is to study differences in the fiscal dynamics of eight EMU countries and assess the role of political variables in shaping those dynamics. We find that elections negatively affect government revenue in Austria, Belgium, Portugal, Spain and Germany. Expenditure, on the other hand, responds positively to incoming elections in Portugal, Italy, France and Netherlands, and negatively in the case of Germany.
