NSP work project investment styles

This paper analyzes the Nova Student Portfolio (NSP) with the objective to understand performances of the fund. Each investment style has been analyzed (growth, value and momentum) in order to highlight what style allocation contributed positively and which had a negative impact. The results show that the team mainly invested in value stocks, which contributed positively but that its growth investments had a negative impact on the stock picking performance. The stock selection shows a major influence of the value investment style. A statistical approach shows that the market factor was the one explaining the most the NSP returns.

A segurança dos consumidores

The present report, about consumer’s safety, shows the development of the knowledge on this particular subject and the actions carried out by entities that fight for the protection of consumer’s rights. The internship was based on the knowledge acquirement on the theoretical and practical aspects of the fight lead by the Direção Geral do Consumidor, together with other entities, towards the elimination or solely the reduction of risks caused by some products and services made available for the consumers or put on the market. During the internship, I counted with the support of my supervisor in the DGC, Dr. Ana Catarina Fonseca and, for the writing of the report, I had the help of my thesis advisor, Dr. Jorge Morais Carvalho, whenever I needed constructive criticism. My participation on the creation of the informative brochures about consumer’s safety, and the study of the legislation used by the DGC on the daily work, enabled me, effectively, to consolidate my guiding principles as a future professional on the matters of the creation of entities, private and public, which aim to ensure the protection of consumers’s rights, informing them of the possible risks or solving the already existing problems, removing dangerous products and services from the market.The report clarifies the action of the DGC on the protection of consumer’s safety, and enables some knowledge on the relations between the entities that work for the protection of the consumers and the market operators and on their work on identifying dangerous products and warning the consumers about it. The final part of this report contains information that allows us to form an idea of the importance that consumer safety has had in Cape Verde, compared with the laws of Portugal on the matter.

Sintomatologia musculoesquelética auto-referida por enfermeiros em meio hospitalar

RESUMO - As lesões musculoesqueléticas ligadas ao trabalho (LMELT) são frequentes em contexto hospitalar e particularmente entre os enfermeiros (Estryn-Béhar, 1991; NIOSH, 1997). Em meio ocupacional o diagnóstico destas patologias é, com frequência, realizado com recurso a questionários de sintomas. A aplicação de questionários de auto-referência de sintomas de LMELT tem permitido recolher informação sobre a prevalência europeia destas lesões, registando-se valores que oscilam entre os 17 e os 44% (Buckle, 1999) e entre nós, designadamente numa indústria de componentes automóveis, os valores apresentam dimensão semelhante ou superior (Serranheira et al., 2003). O presente estudo pretendeu identificar a sintomatologia musculoesquelética auto-referida pelos enfermeiros em meio hospitalar, procurando relações com a actividade de enfermagem. Utilizou-se um instrumento de recolha de informação construído a partir de uma adaptação do questionário nórdico musculoesquelético (QNM) (Kuorinka et al., 1987) que se aplicou a 899 enfermeiros de diferentes serviços em cinco hospitais da região do grande Porto, no ano de 2004 (responderam 507 enfermeiros). Os resultados evidenciam uma prevalência elevada de sintomas musculoesqueléticos em diferentes zonas anatómicas nos últimos 12 meses (84%), particularmente atingindo a região lombar (65%), cervical (55%), dorsal (37%), ombros (34%) e punhos/mãos (30%). Não se encontram associações significativas entre algumas actividades que os enfermeiros realizam e a presença de níveis de desconforto, incómodo ou dor com origem no sistema musculoesquelético, eventualmente devido ao elevado número de subactividades desempenhadas pelos enfermeiros. Apesar disso, existem algumas relações: (1) com a tipologia de actividades realizadas (por exemplo levantamento e transporte de cargas) nos diferentes serviços (destaca-se a Medicina e a Neonatologia), (2) com o aumento do número de horas de trabalho semanais. Desse modo, observa-se que a prevalência de sintomas de LMELT neste grupo profissional é elevada o que pode condicionar a actividade dos enfermeiros e, por consequência, o bem-estar dos utentes. Sugere-se que a actividade de enfermagem e a organização do trabalho deste grupo profissional sejam objecto de uma análise mais detalhada no sentido da identificação dos elementos determinantes da sintomatologia musculoesquelética e sua consequente prevenção.

A videovigilância no local de trabalho

The emergence of new technologies has introduced significant changes in the citizens life’s. There is a constant evolution of technological means and profound impact of their use in the habits of life of the human being. These new technological media are important tools in labor relations. The working and businesses worlds are increasingly turning to these new technologies, so that the use of video surveillance in the workplace is nowadays common. New technologies in general and the use of video surveillance in workplace in particular are providing ways to allow control of the work performance that are desired by most employers. However, the collection of images in the workplace often collides with the fundamental rights and freedoms of workers, in particular, with the right to privacy. The subject concerns the question of investigating is whether the images collected in workplace can be used as evidence in disciplinary proceedings. In fact, this issue is controversial. Doctrine and jurisprudence defend, at least, two responses for the same question. Those who understand that the evidence may be admitted for not violate any right of the worker, and others who argue that the evidence should not be admitted in disciplinary office. In the Portuguese legal system, there is, even, a new intermediate theory that begins to be defended, that only on certain occasions the evidence may be admitted. The solution to this problem involves the study of employment law and data video surveillance processing. Analysis of workers fundamental rights is fundamental to come to a grounded conclusion.

Public diplomacy : Relatório de Estágio na Embaixada dos Estados Unidos em Lisboa

O OPA da Embaixada dos EUA é o departamento responsável por todos os eventos e relações públicas da Embaixada, assim como todos os programas de intercâmbio educacionais e culturais, com o âmbito de promover a política externa americana, assim como os seus valores. O departamento é principal ponto de contato com os meios de comunicação, organizações e pessoas individuais que queiram obter informações sobre os EUA. Além das tarefas desenvolvidas, enquanto estagiária, no âmbito da linha de trabalho do OPA, o presente relatório contém uma contextualização e enquadramento histórico sobre a PD. A PD tem como objetivo promover os interesses nacionais e a política externa, além de informar e influenciar os públicos estrangeiros sobre a sociedade norte-americana e o Governo dos EUA. Todo o trabalho desempenhado no OPA está intrinsecamente ligado à PD e por isso este relatório está dividido em duas partes: a descrição das minhas atividades no departamento e o trabalho de investigação sobre a PD.

Durability indicators comparison for SCC and CC in tropical coastal environments

Self-compacting concrete (SCC) demands more studies of durability at higher temperatures when subjected to more aggressive environments in comparison to the conventional vibrated concrete (CC). This work aims at presenting results of durability indicators of SCC and CC, having the same water/binder relations and constituents. The applied methodologies were electrical resistivity, diffusion of chloride ions and accelerated carbonation experiments, among others, such as microstructure study, scanning electron microscope and microtomography experiments. The tests were performed in a research laboratory and at a construction site of the Pernambuco Arena. The obtained results shows that the SCC presents an average electrical resistivity 11.4% higher than CC; the average chloride ions diffusion was 63.3% of the CC; the average accelerated carbonation penetration was 45.8% of the CC; and the average open porosity was 55.6% of the CC. As the results demonstrated, the SCC can be more durable than CC, which contributes to elucidate the aspects related to its durability and consequent prolonged life cycle.

Modern optimization in earthwork construction

Earthworks tasks are often regarded in transportation projects as some of the most demanding processes. In fact, sequential tasks such as excavation, transportation, spreading and compaction are strongly based on heavy mechanical equipment and repetitive processes, thus becoming as economically demanding as they are time-consuming. Moreover, actual construction requirements originate higher demands for productivity and safety in earthwork constructions. Given the percentual weight of costs and duration of earthworks in infrastructure construction, the optimal usage of every resource in these tasks is paramount. Considering the characteristics of an earthwork construction, it can be looked at as a production line based on resources (mechanical equipment) and dependency relations between sequential tasks, hence being susceptible to optimization. Up to the present, the steady development of Information Technology areas, such as databases, artificial intelligence and operations research, has resulted in the emergence of several technologies with potential application bearing that purpose in mind. Among these, modern optimization methods (also known as metaheuristics), such as evolutionary computation, have the potential to find high quality optimal solutions with a reasonable use of computational resources. In this context, this work describes an optimization algorithm for earthworks equipment allocation based on a modern optimization approach, which takes advantage of the concept that an earthwork construction can be regarded as a production line.

The impact of work clothing design on workers’ comfort

Physical and physiological comfort, at work and during leisure time, is important to human health and motivation. A growing number of jobs require workers to sit. Most clothes, except those intended for wheelchair users, were designed for walking or the standing position. Clothing designs should be user-oriented and meet users’ needs. Garment design should conform to body position and posture, not just shape and size. In this paper we present the ergometric impact of a new type of trousers designed to adapt to changes in position. Concentrations of compression forces, temperature and pressure were documented in an exploratory pilot study and contrasted to traditional designs. The new trousers showed significant decreases in compression force concentration, especially in and around the knees and waist. Most participants identified comfort as an important factor when purchasing a pair of trousers and that, for working purposes, they would prefer these special trousers rather than traditional designs.

Emotional aspects of childhood career development: importance and future agenda

Childhood is a central period for career and social-emotional development. However, the literature covering childhood career development and the role of emotions in careers is scarce. In this article, we advocate for the consideration of emotions in childhood career development. Emotional aspects of children’s career exploration, key-figures and interests, as well as of childhood antecedents of lifelong career processes are presented. Relations between childhood emotion, behavior, functioning and learning are also presented. Conclusions center on a call for focused study of the role of emotion in childhood career development and how such an agenda will advance the literature.

Extracting kinetic information from literature with KineticRE

To better understand the dynamic behavior of metabolic networks in a wide variety of conditions, the field of Systems Biology has increased its interest in the use of kinetic models. The different databases, available these days, do not contain enough data regarding this topic. Given that a significant part of the relevant information for the development of such models is still wide spread in the literature, it becomes essential to develop specific and powerful text mining tools to collect these data. In this context, this work has as main objective the development of a text mining tool to extract, from scientific literature, kinetic parameters, their respective values and their relations with enzymes and metabolites. The approach proposed integrates the development of a novel plug-in over the text mining framework @Note2. In the end, the pipeline developed was validated with a case study on Kluyveromyces lactis, spanning the analysis and results of 20 full text documents.

Libellulidae (Insecta: Odonata) from Itapiracó reserve, Maranhão, Brazil: new records and species distribution information

In this work, I apply a simple protocol to species occurrence inventory of Odonata in a region of Maranhão state which has very few distributional records. Some relations between species occurrence and environmental characteristics are discussed, mainly in relation to the high occurrence of Erythemis. Eighteen new records are presented discussing the role of this approach to generate useful information for conservation purposes.
