Juniperus navicularis - a study of Portuguese population structure and fitness

Juniperus navicularis Gand. is a dioecious endemic conifer that constitutes the understory of seaside pine forests in Portugal, areas currently threatened by increasing urban expansion. The aim of this study is to assess the conservation status of previously known populations of this species located on its core area of distribution. The study was performed in south-west coast of Portugal. Three populations varying in size and pine density were analyzed. Number of individuals, population density, spatial distribution and individual characteristics of junipers were estimated. Female cone, seed characteristics and seed viability were also evaluated. Results suggest that J. navicularis populations are vulnerable because seminal recruitment is scarce, what may lead to a reduction of genetic variability due solely to vegetative propagation. This vulnerability seems to be strongly determined by climatic constraints toward increasing aridity. Ratio between male and female shrubs did not differ from 1:1 in any population. Deviations from 1:1 between mature and non-mature plants were found in all populations, denoting population ageing. Very low seed viability was observed. A major part of described Juniperus navicularis populations have disappeared through direct habitat loss to urban development, loss of fitness in drier and warmer locations and low seed viability. This study is the first to address J. navicularis conservation, and represents a valuable first step toward this species preservation.

The influence of forest management on bird communities of portuguese montados

The world distribution of cork oak Quercus suber and holm oak Q. rotundifolia is basically restricted to the western Mediterranean basin. These two evergreen oaks are the base of the Portuguese montado and the Spanish dehesa. This thesis aims to analyse how bird communities of the montado are influenced by management practices. We used different approaches to study this relationship, and to evaluate which features are responsible for species distribution in different typologies of montado. First, we reviewed the concept of montado in order to better understand the system and to set thresholds on what can be considered as montado. Afterwards, we studied the elements that promote higher species diversity and individual species, or group of species, that can act as indicators of High Nature Value for montados. Finally, we evaluated how the bird communities are structured, and the influence of the main management actions (e.g. cattle and cork exploitation) on those communities; Resumo: A distribuição mundial do sobreiro Quercus suber e da azinheira Quercus rotundifolia é praticamente restrita à bacia do Mediterrâneo. Estas duas espécies de carvalhos são a base dos montados em Portugal e das dehesas em Espanha. No âmbito desta tese analisamos como as comunidades de aves do montado são influenciadas pela gestão florestal. Para este efeito usámos diferentes abordagens e avaliámos quais as características do montado responsáveis pela distribuição das espécies ao longo das suas diferentes tipologias. Fizemos uma revisão do conceito de montado e proposemos uma definição para o sistema, englobando a sua multifuncionalidade. Estudámos os elementos singulares que promovem a diversidade de aves e que podem ser simultaneamente indicadores de áreas de Alto Valor Natural (HNV). Por fim, avaliámos qual a influência da gestão (p. ex. pastoreio e descortiçamento) na estruturação das comunidades de aves.

The marriage of João de Alarcão and Margarida Soares and the creation of a transnational Portuguese-Spanish nobility

The main aim of this chapter is to analyze the social and political effects of dynastic marriages between the Portuguese and Castilian-Aragonese crowns on the configuration of transnational, aristocratic families during the sixteenth and seventeenth centuries. To illustrate these questions we have chosen to follow the Soares de Alarcão family (known in Spain as Suárez de Alarcón) and the paths it took between the royal houses of Portugal and Castile for seven generations. The working hypothesis of the chapter is that the identity of the Iberian nobility during this era was characterized by a shared noble culture rather than by any particular features derived from the family’s land of origin. That assumption allows us to discuss whether the use of a particular language or culture indicates ties or political loyalties based on criteria of nationality, or, at the very least, place of birth. Therefore, this essay discusses the miscegenation of Iberian nobilities derived from dynastic marriages. It articulates the structural characteristics of this group and its political impact with the individual trajectories and historical contexts in which they developed. While these topics can be of interest for the comprehension of Portuguese early modern history, they can also help us to reflect more broadly on processes of identity construction.

Genetic diversity of entomopathogenic nematodes (Nematoda: Steinernematidae and Heterorhabditidae) and the nematode Bursaphelenchus xylophilus (Nematoda: Aphelenchoididae) from continental Portugal

“Diversidade genética dos nemátodes entomopatogénicos (Nematoda: Steinernematidae e Heterorhabditidae) e do nemátode Bursaphelenchus xylophilus (Nematoda: Aphelenchoididade) em Portugal continental” Os nematodes entomopatogénicos são utilizados como agentes de controlo biológico. Para compreender a sua diversidade, foi realizada uma prospecção em Portugal. Cinco espécies, nomeadamente Steinernema feltiae, S. intermedium, S. kraussei, Steinernema sp. e Heterorhabditis bacteriophora foram identificadas. As sequências de ITS, região D2D3 do 28S rRNA, COXI e cytb foram utilizadas para estudar a diversidade genética das duas espécies mais abundantes, S. feltiae and H. bacteriophora, não tendo sido encontradas diferenças significativas entre isolados. O nemátode da madeira do pinheiro, Bursaphelenchus xylophilus, provoca doença nos pinheiros tendo sido detectada pela primeira vez na Europa e em Portugal em 1999. Para avaliar a diversidade genética dos isolados Portugueses e identificar o padrão de propagação da doença, foram utilizadas a sequência da região IGS do 5.8S rRNA, e os genes cytb e cellulase, combinados com os padrões ISSR. Os padrões de ISSR mostraram elevada diversidade genética entre os recentes isolados Portugueses, sugerindo a possibilidade de uma nova introdução. As árvores filogenéticas dos genes da celulase e cytb sugeriram uma origem Asiática para os isolados Portugueses; ABSTRACT: Entomopathogenic nematodes are used as biocontrol agents. To understand their diversity, a survey was undertaken in Portugal. Five species, namely Steinernema feltiae, S. intermedium, S. kraussei, Steinernema sp. and Heterorhabditis bacteriophora were identified. The ITS, 28S rRNA D2D3 region, COXI and cytb sequences, used to study the genetic diversity of the two most abundant species, S. feltiae and H. bacteriophora, showed no significant differences among the isolates. Bursaphelenchus xylophilus causes severe disease in pine trees and was detected for the first time in Europe and in Portugal in 1999. To evaluate the genetic diversity of Portuguese isolates and identify disease spread pathways, the sequence of 5.8S rRNA IGS region, cytb and cellulase genes, combined with ISSR fingerprints were used. ISSR fingerprints show a high genetic variability among recent Portuguese isolates, suggesting the possibility of a new introduction. Phylogenetic trees based on cellulase and cytb genes suggests an Asian origin for Portuguese isolates.

Impact of IS/IT Investments on Firm Performance: Does Stakeholder Orientation Matter?

This research project addresses a central question in the IS business value field: Does IS/IT investments impact positively on firm financial performance? IS/IT investments are seen as having an enormous potential impact on the competitive position of the firm, on its performance, and demand an active and motivated participation of several stakeholder groups. Actual research conducted in the Information Systems field, relating IS/IT investments with firm performance use transactions costs economics and resource-based view of the firm to try to explain and understand that relationship. However, it lacks to stress the importance of stakeholder management, as a moderator variable in that relationship. Stakeholder theory sees the firm as the hub centric to the spokes representing various stakeholders who were in essence equidistant to the firm, and survival and continuing profitability of the corporation depend upon its ability to fulfil its economic and social purpose, which is to create and distribute wealth or value sufficient to ensure that each primary stakeholder group continues as part of the corporation’s stakeholder system. Stakeholder theory in its instrumental version, argues that if a firm pays attention to the stakes of all stakeholder groups (and not just shareholders), it will obtain higher levels of financial performance. With this premise in mind, the aim of this paper is to discuss and test the use of stakeholder theory in the IS business value stream of research, in order to achieve a better understanding of the impact of IS/IT investments on firm performance (moderated by stakeholder management). To achieve the expected impact from an IS/IT investment, it is argued that firms need a strong commitment from those stakeholder groups, which lead us to the need of a corporate “stakeholder orientation”. When firm financial performance is measured by returns on assets (ROA), returns on investments (ROI) and returns on sales (ROS), the results show that “stakeholder orientation” impact positively in the relation between IS/IT and firm performance, using a sample of Portuguese large companies.

Impact of Information Technology Investments on Firm Productivity in Peripherals Countries: The Case of Portugal

IS/IT investments are seen has having an enormous potential impact on the competitive position of the firm, on its performance, and demand an active and motivated participation of several stakeholder groups. The shortfall of evidence concerning the productivity of IT became known as the ‘productivity paradox’. As Robert Solow, the Nobel laureate economist stated “we see computers everywhere except in the productivity statistics”. An important stream of research conducted all over the world has tried to understand these phenomena, called in the literature as «IS business value» field. However, there is a gap in the literature, addressing the Portuguese situation. No empirical work has been done to date in order to understand the impact of Information Technology adoption on the productivity of those firms. Using data from two surveys conducted by the Portuguese National Institute of Statistics (INE), Inquiry to the use of IT by Portuguese companies (IUTIC) and the Inquiry Harmonized to (Portuguese) companies (accounting data), this study relates (using regression analysis) the amounts spent on IT with the financial performance indicator Returns on Equity, as a proxy of firm productivity, of Portuguese companies with more than 250 employees. The aim of this paper is to shed light on the Portuguese situation concerning the impact of IS/IT on the productivity of Portuguese top companies. Empirically, we test the impact of IT expenditure on firm productivity of a sample of Portuguese large companies. Our results, based on firm-level data on Information Technology expenditure and firm productivity as measured by return on equity (1186 observations) for the years of 2003 and 2004, exhibit a negative impact of IT expenditure on firm productivity, in line with “productivity paradox” claimants.

Trans-national cooperation: an asset in the Portuguese overseas trade. Foreigners operating in the Portuguese overseas trade, 1580-1590

This paper aims to discuss the role of foreign merchants, operating from Portugal, in the Portuguese overseas trade, during the first ten years of Iberian Union. The focus is not in products or routes, but in the mechanisms of association of such merchants. Iberian Union created a legal framework which prohibited the interference and trade of Portuguese agents in the Spanish Empire and vice-versa. Due to the imperialist wars of the Habsburgs, the Portuguese Empire also suffered from Dutch and English rivalry both in the Indic and in the Atlantic and also from the embargos of Dutch and English products and ships in Iberian ports. In such conjuncture, how did merchants related with each other? What was the impact of the political union of the Portuguese and Spanish crowns in trading associations? The used data sources are the notarial contracts of Lisbon for the same period. The paper highlights the role of Castilian merchants in the Portuguese trade, but it also stresses that Iberian partnerships have prevailed before 1580. The role of other merchants, such as Flemish/Dutch, Germans, Italians and French, is also considered. The paper discusses how and why did these merchants join in trans-national partnerships and what was their role in the Portuguese trade network at the time.

Antioxidant and anti-inflammatory potential of Lavandula spp.

Lavenders have been used in folk medicine as disinfectant, expectorant, analgesic, anti-spasmodic, laxative and stimulant. Some species are endemic of Iberian Peninsula and often found in the Portuguese montado, including Lavandula stoechas subsp. luisieri and Lavandula pedunculata. The investigation of the antioxidant and anti-inflammatory potential of the Portuguese montado flora is very poor and restricted to a few botanical families, and their biological activities are mainly attributed to the essential oils. So, it is crucial to know the properties of Lavandula EOs, contributing for animal health and the valorisation of Portuguese montado flora. The aim of this study was to evaluate chemical composition, antioxidant properties and screening anti-inflammatory potential of EOs and extracts of Lavandula stoechas L. subsps. luisieri Rozeira, Lavandula pedunculata (Mill.) Cav. subsp. pedunculata and Lavandula viridis L’Hér, wild grown in the south of Portugal.

The Influence of Age and Size on Family-Owned Firms’ Financing Decisions: Empirical Evidence Using Panel Data

Based on four samples of Portuguese family-owned firmsdi) 185 young, low-sized family-owned firms; ii) 167 young, high-sized familyowned firms; iii) 301 old, low-sized family-owned firms; and iv) 353 old, high-sized family-owned firms d we show that age and size are fundamental characteristics in family-owned firms’ financing decisions. The multiple empirical evidence obtained allows us to conclude that the financing decisions of young, low-sized family-owned firms are quite close to the assumptions of Pecking Order Theory, whereas those of old, high-sized family-owned firms are quite close to what is forecast by Trade-Off Theory. The lesser information asymmetry associated with greater age, the lesser likelihood of bankruptcy associated with greater size, as well as the lesser concentration of ownership and management consequence of greater age and size, may be especially important in the financing decisions of family-owned firms. In addition, we find that GDP, interest rate and periods of crisis have a greater effect on the debt of young, low-sized family-owned firms than on that of family-owned firms of the remainder research samples.

Does partial privatisation improve performance? Evidence from a chain of hotels in Portugal

This article contributes to the literature by testing six research hypotheses regarding the impact of partial privatisation on firms' performance. We measure performance using Data Envelopment Analysis (DEA), the Malmquist Index and ratios related to labour productivity, profitability and capacity utilisation. We use the Wilcoxon Signed Rank test to compare the performance after privatisation with that before privatisation. The hypotheses are tested with data from a chain of Portuguese heritage hotels, partially privatised in 2003. We conclude that productivity growth after privatisation is superior to productivity growth before privatisation due to technological progress. However, due to a frontier regress observed in the privatisation year, total factor productivity and profitability deteriorated after privatisation. This suggests that both efficiency changes and frontier shifts should be taken into account in order to accurately assess the impact of privatisation.

A aprendizagem da leitura : Concepções sobre a funcionalidade da linguagem escrita e o sucesso na leitura no final do 1º ano de escolaridade

A Aprendizagem da Leitura é um desafio para as crianças que iniciam o primeiro ano de escolaridade tomando-se, para algumas, difícil de alcançar e influenciando negativamente todo o seu percurso escolar. O objectivo deste estudo é procurar perceber qual a relação entre os conhecimentos/concepções que as crianças do primeiro ano de escolaridade possuem, no início do ensino básico, sobre os objectivos/funções da leitura e o sucesso na sua aprendizagem no final do ano lectivo. A amostra foi constituída por 59 crianças, de nacionalidade portuguesa, que no ano lectivo 2006/2007 frequentaram pela primeira vez o primeiro ano de escolaridade, nas Escolas Básicas do 1o Ciclo do Agrupamento de Escolas de Arraiolos e que ainda não saibam ler no início do ano lectivo. A recolha de dados foi feita em dois momentos: no início e no final do ano lectivo. No primeiro momento, em Setembro e Outubro de 2006, foi feita às crianças uma entrevista individual semi-directiva (Alves Martins, 2000), que permitiu conhecer as suas concepções funcionais da leitura e foi também aplicada a Prova de Linguagem Técnica da Leitura/Escrita (Alves Martins, Mata, Peixoto & Monteiro, 2000), para avaliar os conhecimentos de linguagem técnica das crianças; no segundo momento, em Junho de 2007, foi aplicada uma Prova de Leitura (Alves Martins, 2000), para avaliar o desempenho em leitura no final do ano lectivo. Para o tratamento dos dados, a metodologia que utilizámos combinou a análise qualitativa e a análise quantitativa Relativamente à entrevista recorremos à análise qualitativa - análise de conteúdo, quanto à Prova de Linguagem Técnica da Leitura/Escrita e à Prova de Leitura foi feita uma análise quantitativa, seguindo o tratamento estatístico a metodologia proposta pelos autores das provas. ABSTRACT; The Learning of the Reading is a challenge to children who begin the first school year, becoming, for some of them, difficult to achieve and influencing in a negative way their entire school itinerary. The purpose of this study is to try to understand what the relation is between the knowledge/conceptions children in the first school year possess, at the beginning of the elementary education, about the purposes/functions of reading and the success of their learning at the end of the school year. The sample was constituted by 59 children, of Portuguese nationality, that in the school year of 2006/2007 attended for the first time the first school year, in the Elementary Schools of the 1st Cycle of the Assemblage of Schools of Arraiolos and that could not read in the beginning of the school year. The joining of data was made in two moments: in the beginning and in the end of the school year. ln the first moment, in September and October 2006, an individual semi­directive interview (Alves Martins, 2000) was made to the children, which allowed to know their functional conceptions of reading and was also made the Proof of Technical Language of Reading/Writing (Alves Martins, Mata, Peixoto & Monteiro, 2000), in order to evaluate the children's knowledge of technical language; in the second moment, in June 2007, a Proof of Reading (Alves Martins, 2000) was made, to evaluate the performance in reading at the end of the school year. For data treatment, the method we used combined the qualitative analysis and the quantitative analysis. About the interview, we used the qualitative analysis-content analysis, about the Proof of Technical Language of Reading/Writing and the Proof of Reading was made a quantitative analysis, having the statistic treatment followed the method proposed by the authors of the proofs.

A avaliação de desempenho docente vista por professores: realidades, expetativas, desafios e oportunidades

A avaliação de desempenho docente tem sido considerada o alfa e o ômega dos sistemas educativos, nas últimas décadas. Em Portugal, desde 2007, esta questão tornou-se mais acutilante devido às alterações introduzidas no Estatuto da Carreira Docente que originaram uma alteração profunda nas práticas de avaliação do desempenho docente. A implementação do novo modelo despoletou forte resistência por parte destes profissionais, alimentada por uma base concetual distante da realidade das escolas portuguesas e por tibiezas na execução do processo de avaliação. O principal objetivo deste estudo consistiu em apresentar os contributos de professores para um modelo de avaliação do desempenho docente, assumindo as expetativas e as perceções destes profissionais como referente imprescindível para a sustentabilidade avaliativa do modelo. Para além disso, procedeu-se a uma breve descrição e avaliação do modelo de avaliação docente, implementado entre 2007 e 2011, recuperando perceções depuradas pelo tempo. O estudo, descritivo e inferencial, conciliou abordagens de natureza quantitativa e qualitativa, tendo recorrido a um questionário, aplicado a 585 docentes em funções no Algarve, e à entrevista, realizada a quatro informadores privilegiados do processo avaliativo. Os resultados alcançados apontaram para i) de um conjunto de pareceres favoráveis face a alguns aspetos do modelo de avaliação vigente entre 2007 e 2011; ii) uma avaliação globalmente negativa do mesmo modelo, iii) a definição de componentes das diferentes dimensões de modelo avaliativo, onde se identificou a preponderância da vertente formativa; a articulação da avaliação dos docentes com a avaliação de escola e com outros documentos de gestão escolar; a coincidência dos ciclos avaliativos com a progressão na carreira; a autoavaliação como principal instrumento de recolha de dados; a observação facultativa de aulas; a existência de avaliadores com formação em supervisão ou avaliação e capacitados com um perfil adequado; e o uso dos resultados da avaliação para a melhoria das práticas letivas e para a progressão na carreira, sendo ainda de considerar a possibilidade de acionar mecanismos de recuperação, caso existissem indicadores de insucesso na prática profissional do docente. O estudo termina com o enunciado de recomendações para a reconceptualização do modelo de avaliação dos docentes, permitindo reconhecer e eliminar os fatores conflituantes, tendo em vista a concretização da avaliação docente como estratégia impulsionadora da melhoria do desempenho dos professores, da escola e do sistema educativo. Palavras-chave: avaliação educacional; avaliação de desempenho docente; modelos de avaliação de desempenho docente; desenvolvimento profissional do professor, educadores e professores dos ensinos básico e secundário; ABSTRACT:Teacher performance appraisal has been considered the alpha and omega of educational systems in recent decades. In Portugal, since 2007, this issue has become more incisive due to amendments to the Teaching Career Statute that brought deep changes in assessment practices of teacher performance. The application of the new system has triggered strong resistance by these professionals, powered by a distant conceptual basis of the reality of Portuguese schools and weaknesses in the implementation of the appraisal process. The aim of this study is to present the teachers contributions to this teacher performance appraisal model, taking the expectations and perceptions of these professionals as an essential reference for the sustainability of the appraisal process. In addition, a brief description and evaluation of the teacher performance appraisal model, implemented between 2007 and 2011, was given, recovering perceptions filtered by time. The study, descriptive and inferential, reconciled quantitative and qualitative approaches, has used a questionnaire applied to 585 teachers serving on the Algarve, and an interview to four held key informants of the teacher appraisal process. The achieved results showed i) a set of favorable opinions about some aspects of the current evaluation model between 2007 and 2011; ii) a generally negative evaluation of the same model, iii) the definition of components of different dimensions of the appraisal system, which showed preponderance of formative purposes; the joint assessment of teachers with school evaluation and other school management documents; the coincidence of the evaluation cycles with career advancement; self-evaluation as the main data collection instrument; the optional classroom observation; the existence of evaluators under supervision in training or evaluation and empowered with the right profile; and the use of evaluation results to improve teaching practices and to career advancement, still considering the possibility of using recovery mechanisms if there were failure indicators in professional teaching practice. The study ends with the statement of recommendations for the reconceptualization of teacher performance appraisal, which allowed to recognize and eliminate conflicting factors, with a view to implementing the teaching appraisal as a compelling strategy for improving teacher performance, school and educational system. Keywords: educational evaluation; teacher performance appraisal; teacher performance appraisal systems; teacher professional development; early years teachers, primary and secondary school teachers.

Determinantes da estrutura de capitais do sector bancário português

Este estudo tem como objectivo analisar quais os factores que determinam a estrutura de capitais do sector bancário Português. Com o intuito de atingir o objectivo e assumindo a existência de uma estrutura óptima de capitais, recorrer-se-á ao modelo de regressão linear múltipla para verificar a aderência do processo de decisão às teorias acerca da estrutura de capitais, bem como quais dos factores analisados a afectarão significativamente. Os resultados obtidos sugerem que a rendibilidade, a dimensão, o risco e a tangibilidade são os principais determinantes da estrutura de capitais do sector bancário português. ABSTRACT: The main aim for this study is to verify which determinants influence the Portuguese bank's capital structure. ln order to achieve the above mentioned aim and assuming an optimal capital structure, we will apply a multiple linear regression model with the purpose of proving the capital structure theories existence and to observe which determinants influence it. The obtained results mention that profitability, size, risk and tangibility are the principal determinants of Portuguese bank's capital structure.

De cerca conventual a espaço público: o convento do Beato António como caso de estudo

RESUMO: A cidade de Lisboa acolheu vários conventos e mosteiros que, apesar de actualmente albergarem diversas funções que não a religiosa, persistem na malha urbana da cidade. As antigas cercas conventuais e monásticas que perduraram conservam-se como lugares verdes da cidade. Estas áreas na sua maioria, jardins privados. Contudo, na zona ocidente de Lisboa, duas cercas conventuais são hoje exemplos notáveis de jardins públicos. São os casos da cerca do Convento de Nossa Senhora das Necessidades - hoje o Jardim da Tapada das Necessidades -, e da cerca do Mosteiro de Nossa Senhora da Estrela - hoje o Jardim da Estrela. Este trabalho, com base no estudo do Jardim da Tapada das Necessidades e do Jardim da Estrela, e na essência do jardim português procura estabelecer uma hipótese de intervenção nas cercas de Lisboa. Assim, é proposta a recuperação da cerca conventual do Beato António como espaço de jardim público. Desta forma, este trabalho não só contribui para o conhecimento sobre as cercas conventuais e monásticas de Lisboa, como para a enunciação de uma possível metodologia de intervenção nestes conjuntos; ABSTRACT: The city of Lisbon hosted several convents and monasteries that although currently harboring various functions other than religious, persist in the city. The old convent and monastic fences that lasted are preserved as green places in town. These areas are mostly private gardens. However, in the western part of Lisbon, two conventual fences are outstanding examples of public gardens. This is the case of the Nossa Senhora das Necessidades Convent - now the Jardim das Necessidades - and of the Monastery of Nossa Senhora da Estrela - now the Jardim da Estrela. This paper, based on the study of the Jardim das Necessidades and the Jardim da Estrela, and on the essence of Portuguese gardens, seeks to establish a hypothesis of intervention on the fences of Lisbon. It is therefore proposed to recover the conventual fence of Beato Antonio as a public garden space. Thus, this thesis not only contributes to the knowledge of the Lisbon's conventual and monastic fences, as to the enunciation of a possible intervention methodology in these sets.
