What makes people stay in or leave shrinking cities? An empirical study from Portugal

The relative attractiveness of cities as places to live determines population movements in or out of them. Understanding the appealing features of a city is fundamental to local governments, particularly for cities facing population decline. Pull and push attributes of cities can include economic aspects, the availability of amenities and psychological constructs, initiating a discussion around which factors are more relevant in explaining migration. However, a pull–push approach has been underexplored in studies of shrinking cities. In the present study, we contribute to the discussion by identifying pull and push factors in Portuguese shrinking cities. Data were collected using a face-to-face questionnaire survey of 701 residents in four shrinking cities: Oporto, Barreiro, Peso da Régua and Moura. Factor analysis and automatic linear modelling were used to analyse the data. Our results support previous findings that the economic activity of a city is the most relevant feature for retaining residents. However, other characteristics specific to each city, especially those related to heritage and natural beauty, are also shown to influence a city’s attractiveness as a place to live. The cause of population shrinkage is also found to influence residents’ assessments of the pull and push attributes of each city. Furthermore, the results show the relevance of social ties and of place attachment to inhabitants’ intention to continue living in their city of residence.

Evaluation of drought tolerance in several genotypes of spelt (Triticum aestivum Var. Spelta)

Domestication of plants and plant breeding have dramatically eroded the allelic variations of crop species which led to an increasing susceptibility of crop plants to environmental stresses, diseases and pests. Drought is a major environmental stress factor that affects the growth and development of plants so the selection of tolerant genotypes becomes increasingly important with respect to the predicted effects of global warming. In this study, several genotypes of Spelt (Triticum aestivum var. spelta) were tested under low water supply in soil with the aim of to find Spelt genotypes more resistant than wheat to these conditions, and select them so that in future may be used to improve wheat crops. Morphological analyses were performed and mineral and enzymatic analyses and also dry matter production were calculated. Our results suggests that the genotypes Sp53, Sp96, Sp912, Sp757 and Sp804 are a potential ones to use in breeding programs to improve wheat production. Under drought, these genotypes had growth efficiency of 38%, 45%, 64%, 37%, and 31% respectively and also showed higher biomass than modern wheat and were also mineralogical richer. The genotypes Sp96 and Sp912 showed highest activity of all antioxidants enzymes tested. This work proves that Spelt is a good wheat to continue to study in order to improve wheat crops in dry areas and consequently increase the quality of life and health of the populations living in those areas.

Avaliação do desempenho das políticas de defesa costeira: obras de defesa costeira de 1995 a 2014. Contributo para o Sistema de Administração do Recurso Litoral (SIARL)

O presente trabalho constitui um contributo para que a zona costeira continue a ser o que é, ou seja, um lugar aprazível, com praias onde possamos continuar a estender a nossa toalha. Com efeito, grande parte das nossas praias estão a desaparecer devido à erosão costeira, que é um problema que já ultrapassou o limiar do natural e já está a atingir o lado social e económico. A gestão integrada das zonas costeiras (GIZC) é imprescindível e uma questão primordial na defesa do litoral, das pessoas e dos seus bens. Com o apoio da Agência Portuguesa do Ambiente, I.P. (APA, I.P.) foram realizadas recolhas de informação das obras efetuadas no Litoral Continental Português (LCP) com o objetivo, de se avaliar a política de defesa costeira prosseguida até agora. Outro objetivo a atingir com o presente trabalho visa disponibilizar informação que permita carregar o Módulo das Intervenções do Sistema de Administração do Recurso Litoral (SIARL). O SIARL é a principal ferramenta no apoio à gestão integrada das zonas costeiras em Portugal que atualmente existe. É um geoportal que “permite aos organismos com competência no litoral e aos diversos utilizadores, ampliar o conhecimento sobre as dinâmicas costeiras, dominantemente na ótica do risco e do uso dos solos”. A informação recolhida dos processos da APA, I. P. foram convertidas em dados e possibilitou a criação de duas bases de dados, a Base de Dados das Obras Costeiras (BDOC) e os QUADROS ORLA 1995-2014 (QO95) tendo em vista posterior carregamento do SIARL para ficar disponível a todos os que manifestem interesse nesse sentido. A partir destas bases de dados foi possível perceber o montante de investimento envolvido em ações de defesa costeira. O investimento analisado, de cerca de 196 M€, permite perceber como se reparte esse investimento por concelhos, por Planos de Ordenamento da Orla Costeira (POOC), por tipologia de obra e se trata-se de obras reativas ou planeadas, além da distribuição dos investimentos ao longo dos 20 anos analisados. Outro tipo de correlações a extrair é o facto dos troços onde se registam maiores taxas de recuo de linha de costa correspondem aos locais onde ocorrem os maiores investimentos em defesa costeira pesada, como acontece em Esposende, a sul de Espinho e na Caparica. Informação como a que foi analisada no presente trabalho é essencial para outros tipos de abordagens, como seja avaliar as tendências registadas e as esperadas no futuro e permitir equacionar se a politica até agora utilizada é a que nos serve ou se requer reorientação e que de certa forma este trabalho já cumpriu esse objetivo pois parte da informação tratada neste âmbito serviu de base à reflexão do Grupo de Trabalho do Litoral criado através do Despacho nº 6574/2014 de 12 de maio de 2014.

O terrorismo e o impacto nos Direitos Humanos

Terrorism is at the center of speeches in contemporary societies. Terrorism has caused a great instability in Western society, but if before the Islamic fundamentalist terrorism was just a threat to the West, the Arab world of today suffers this same reality. Human rights conquered in the past, are being constantly violated and forgotten by the countries that make them flag of their ideals as the US, that this fight against terrorism already violated in every way those rights. Human rights are the fundamental pillars to be able to live in society and serve to protect the humanity of the atrocities that have been committed in the past with the great wars. Human rights are the fundamental pillars to be able to live in society and serve to protect the humanity of the atrocities that have been committed in the past with the great wars. Atrocities as torture, which is prohibited by several international documents and yet these inhumane practices continue to be used as a means of combating terrorism. Democracies are fragmented and the great challenge facing this century is finding means to contain the growth of these Islamic radicals, without jeopardizing the universally known human values.

How to increase and attract more tourists into Kenya throught experiental marketing

This marketing plan project is a culmination of extensive strategies with the use of experiential marketing to address issues confronting the Kenyan tourism industry in order to have a sustainable tourism sector. Following the terrorist attack carried out by Islamist militants’ belonging to al-Shabaab terrorist organization on Nairobi’s Westgate shopping mall in September 2013, tourist forecast has gone down sharply with an average of 20% fall in tourists’ arrivals which is likely to have an impact on the tourism sector in Kenya. Even before the deadly attack on Westgate, the most lethal attack by Islamist terrorists in 15 years in Kenya, the government through the Kenya tourist board had announced that in 2013 tourist arrivals were down by 12%, at 495,978, according to an October 2013 report by Bloomberg. Tourism revenues were also down by 7.4%, over FY12/13 (July-June) to reach KES96.24bn, according to a September 2013 report on the local Capital FM website. Beyond 2013, much will depend on how quickly the Kenya tourist board can regain control of the situation. The Kenyan government believes that the Westgate mall attack was a 'one-off' incident, with a low probability of a similar event happening again over the short term period. Germany, United States, United Kingdom, Australia, Italy, France and Canada continue to be the key source market however; the Kenya tourist board can make continued growth stronger from new emerging markets in order to increase new arrivals into the country. The marketing plan outlines the objectives to be implemented and provides the implementation strategy, activity plans, monitoring and evaluation plans, financial requirements projections and proposes a new structure of experiential marketing. A number of regional forces are identified that will impact tourism into the country including global, social and economic forces, emerging trends in visitor motivations and behavior, emerging forces in experiential marketing. A major component of the strategy identifies target markets for Kenya to commensurate with the level of resources that will be available for marketing and promotion, in keeping with the forces and trends identified and the nature of the Kenya tourism environment. The agreed upon target market segments are: generic/mass travel, experiential travel, creative travel, adventure seeking travel, senior/extended/long stay travel, and business related travel. The strategy phases the development of the target markets over the years of the marketing strategies in order to yield the best opportunity for results. A core activity in developing a marketing strategy is determining the nature of experiences Kenya offers in tourism. The strategy’s experience development process will continue to develop within the context of the products identified which will be promoted regionally: culture/heritage, nature, community-based. Each county in the country has a significant number of attractions and experiences and the challenge of the country is to bring these together in a creative and innovative way in order to encourage tourists to visit more than one county in Kenya.

Influência da exsudação e da perda de água nas propriedades reológicas de grouts

A sociedade dispõe hoje de um vasto património edificado que na maioria dos casos necessita de conservação para que continue a corresponder às necessidades e expectativas das comunidades. A alvenaria de pedra de múltiplos panos apresenta-se como a solução construtiva mais comum nos centros urbanos europeus. No entanto, a sua conservação requer na maioria das vezes intervenções de consolidação com vista à melhoria das suas características mecânicas e consequente integridade estrutural. A técnica de consolidação por injeção de grouts é uma das mais utilizadas neste tipo de solução construtiva. O trabalho aqui apresentado teve como objetivo contribuir para o conhecimento dos grouts, à base de cal hidráulica, para injeção em alvenarias antigas de três panos. Concretamente, sobre a influência da perda de água e da exsudação nas suas propriedades reológicas. É sabido, que as propriedades no estado fresco dos grouts condicionam a resistência mecânica e durabilidade no estado sólido. Essas estão dependentes da capacidade de penetração nas fendas da alvenaria, preenchimento uniforme dos vazios e da manutenção da homogeneidade do grout, ao longo de todo o processo de reforço. Neste sentido, definiu-se para a campanha experimental a realização de dois tipos de ensaios: fluidez-estabilidade e reométricos, de forma a quantificar os parâmetros definidos, genericamente, pelas propriedades em cima referidas. Durante os ensaios com o reómetro rotacional (pratos paralelos), investigou-se o fenómeno de escorregamento para três formulações de grouts. Foi possível correlacionar a ocorrência deste fenómeno com as condições de ensaio no reómetro (tensão e taxas de corte aplicadas e gap) e com a sua composição, nomeadamente o rácio entre água/ligante. Propôs-se, também, a colagem de uma lixa na superfície da geometria do reómetro, de forma a mitigar a subestimação dos parâmetros reológicos, introduzidas pelo escorregamento.

Desigualdades de saúde no género na população adolescente : tabaco e obesidade

RESUMO - Introdução: Apesar de ocorrerem melhorias significativas na saúde das populações devido aos avanços tecnológicos continuam a surgir desigualdades de saúde no género, nomeadamente na população adolescente, quando estes não adotam comportamentos saudáveis. Objetivos: Analisar as desigualdades de saúde no género na população adolescente relativamente ao tabaco, obesidade e tipo de dieta. Métodos: Foi realizado um estudo analítico e descritivo, onde foram recolhidos dados acerca de fatores relacionados com comportamento, dos quais se destacam o tabagismo, obesidade, e tipo de dieta (consumo de sopa; salada/legumes cozidos; fruta e bolos, chocolates e sobremesa doce) por grupo etário. Dados pertencentes ao INS 2005/2006. Resultados: Verificou-se que a prevalência do tabagismo é estatisticamente significativa relativamente ao género apenas no grupo etário 17-19 anos (p=0). Demonstrou-se que havia associação estatisticamente significativa entre o género e obesidade apenas no grupo etário 10-13 anos (p=0). Quanta à variável tipo de dieta apenas no consumo de fruta existiu associação estatisticamente significativa no género no grupo etário 10-13 anos (p=0,036). Conclusões: Assim, com a realização do estudo verificou-se que o período crítico do consumo tabágico é no grupo etário 17-19 anos, já obesidade são os mais jovens pertencentes ao grupo etário 10-13 anos.

A presunção de inocência nas fases preliminares do processo penal

This study analyses the principle of presumption of innocence in the preliminary stages of the Portuguese criminal process, its procedural aspect related with the principle of in dubio pro reo and its material aspect concerning the treatment of the defendant during the proceedings. The consequences and manifestations of the principle of presumption of innocence are analysed in the decisions of the closing stages of the preliminary criminal procedure and the application of the principle of in dubio pro reo is analysed in the judgement of sufficiency of evidence for the procedure to continue. It addresses the question of circumstantial evidence, its particular relevance in economic and financial crime, highly organized crime, the grounds for the indictment in general and when the sufficiency of evidence criteria is based on that evidence. It analyses the scope of the principle of presumption of innocence in the application of coercive measures, with reference to the arrest, first interrogation of the accused under detention and reasons for the subsequent dispatch about the measures. The asset assurance measures of preventive seizure and the preventive seizure to ensure confiscation are analysed and principle of presumption of innocence is considered non applicable to those measures.

A obrigação alimentar

There is an undeniable link between child support and scholarship, under article 1880 of the portuguese Civil Code. Of course, by being within family relationships, such link could not be out of controversy. At a time when the continuation of studies is more and more urgent, this link between the two, is often subject of disputes, especially resultant from the interpretation of the law, due to the wide extension that it is entitle to; and many times is also insufficient to the most interested people – the youngsters that want to study. Regardless of the imprecision that rules under article 1880 of the portuguese Civil Code, this article reveals a huge importance by enabling young adults and students to continue their studies, with the financial help from their parents - the responsibility of the parents with the support of their children should have ended by the time they have become legal adults, but it is extended by this article, once the criteria is filled, especially related to the reasonableness of what is required to the parents and the temporal duration of the education chosen. That is, considering that reaching adulthood does not cease the duty of support from the parents, it is important to know how much can parents provide to their children, bearing in mind their income and the child’s and his/her needs, behavior and the intellectual capacity of the child as a student and also the parent-child relationship; and, until when is such support due, taking in to account several circumstances of life and the difficulties inherent to the degree chosen and even the extension of the studies to a master or to a PhD degree that justifies the extension of the parent’s duty. Anyway, the application of article 1880 of the portuguese Civil Code is always based on a case by case analysis and on the economic insufficient of the youngsters to suffice themselves and the simultaneous desire to continue their studies.

Princípios de terapêutica antibiótica na doença crítica

RESUMO: A infeção é frequente durante a doença crítica, quer como causa da doença crítica quer como complicação da sua evolução. Paradoxalmente, os avanços da medicina moderna aumentaram eles próprios o risco de infeção, ao permitir a sobrevida até idades avançadas, ao criar um novo grupo de doentes imunodeprimidos, nomeadamente doentes tratados com fármacos que interferem com as suas defesas naturais (corticóides, citostáticos), ao aumentar o tempo de vida de hospedeiros com comorbilidades debilitantes. Os antibióticos são um dos elos essenciais no tratamento da infeção. Contudo o seu uso também promove a seleção e crescimento de bactérias resistentes. Para além disso as doses convencionais de antibióticos foram selecionadas numa altura em que a resistência era um fenómeno raro e podem não ser atualmente as mais adequadas. Existe hoje muita evidência acumulada que os doentes críticos sofrem alterações da sua farmacocinética (PK) que podem facilitar a ocorrência de falência terapêutica ou de toxicidade tanto por sub como por sobredosagem de antibióticos. Essas alterações são complexas e difíceis de estudar. Finalmente, também a farmacodinâmica (PD) dos antibióticos pode estar alterada nesta população, podendo haver necessidade de ajustar os alvos terapêuticos de forma individual. O objetivo deste trabalho foi investigar a relação entre a terapêutica antibiótica, as suas características PK e PD, a carga bacteriana e o prognóstico dos doentes críticos. O plano de investigação incluiu: 1. Dados da epidemiologia portuguesa de doentes críticos com infeção; 2. Avaliação da relação entre a carga bacteriana, o tempo até ao início do tratamento antibiótico e o prognóstico dos doentes críticos; 3. Avaliação da evolução da PK durante o tratamento da infeção; 4. Um estudo multicêntrico para avaliação da eficácia da terapêutica com um β- lactâmico doseado de acordo com a relação PK/PD. Na introdução é descrita a importância dos antibióticos, a sua origem e o problema crescente das resistências bacterianas relacionadas com o seu emprego e abuso. É salientada a importância de racionalizar a posologia, de acordo com os conceitos de PK e de PD. No Capítulo 1 são apresentados dados de epidemiologia portuguesa de infeção em doentes críticos, sobretudo retirados de dois estudos prospetivos, observacionais, os quais incluíram mais de 50% da capacidade de internamento em cuidados intensivos existente em Portugal. No Capítulo 2 são descritos os conceitos de PK e as suas alterações nos doentes críticos. De seguida são revistos os conceitos de PD de antibióticos e a sua aplicação a esta população, em particular durante as infeções graves (Capítulo 3). Nos capítulos seguintes são aprofundadas estas alterações da PK nos doentes críticos e as suas causas, de forma a destacar a importância da monitorização da concentração dos antibióticos. São apresentados os dados duma revisão sistemática de PK de antibóticos nesta população (Capítulo 4), pormenorizadas as alterações da PD que comprometem a eficácia da terapêutica antibiótica, facilitam o desenvolvimento de resistências e podem levar a falência terapêutica (Capítulo 5). Consequentemente a compreensão global destas alterações, da sua relevância clínica e a revisão da evidência disponível facilitou o desenvolvimento do próprio plano global de investigação (Capítulos 6 e 7). No Capítulo 6.1 são descritos os antibióticos tempo-dependente e a importância de aumentar o seu tempo de perfusão. Foi desenhado um estudo multicêntrico para comparar a eficácia e segurança da perfusão contínua da piperacilina tazobactam (um antibiótico β-lactâmico associado a um inibidor de β-lactamases) com a mesma dose do antibiótico, administrado em dose convencional, intermitente. A importância de dosear corretamente os antibióticos concentração-dependente foi também avaliada num estudo a primeira dose dos aminoglicosídeos (Capítulo 6.2). Outras estratégias para melhorar os resultados assistenciais dos doentes infetados são abordadas no Capítulo 7, em particular a importância da terapêutica antibiótica precoce, a avaliação da carga bacteriana e a compreensão da variação da PK ao longo do tratamento da infeção. Foi desenvolvido um algoritmo de abordagem terapêutica que incluiu estas alterações da PK e da PD nos doentes críticos. Finalmente no Capítulo 8 são descritos mecanismos de desenvolvimento das resistências bacterianas bem como estratégias para a sua abordagem. O Capítulo final (Capítulo 9) aponta um plano para futuras áreas de trabalho. O elemento chave identificado neste trabalho de investigação é o reconhecimento da variabilidade significativa da PK dos antibióticos durante a doença crítica, a qual condiciona a sua posologia. Estas alterações estão relacionadas com a própria gravidade da doença e tendem a diminuir ao longo do seu tratamento. No entanto nem a gravidade da doença nem as características individuais as permitem prever de forma aceitável pelo que a utilização duma posologia universal, independente da situação clínica concreta, pode ser inadequada. As estratégias para melhorar os resultados assistenciais dos doentes críticos infetados devem ser baseadas na individualização da posologia antibiótica de acordo com os princípios da PK e da PD, preferencialmente apoiadas em doseamentos da sua concentração. ------------------------------------ ABSTRACT: Infection commonly occurred during critical illness, either as a cause or complicating the course of the disease. Advances in medicine had paradoxically increase the risk of infection, both by improving survival to older ages and by introducing a new group of immunosuppressed patients, those who are treated with drugs that interfere with their natural defenses (corticosteroids, cytostatics) and those who survived longer with aggressive diseases. Antibiotics are of paramount importance for treating infection. However the use of these drugs also promote the selection and growth of resistant bacteria. Furthermore conventional antibiotic doses were calculated for less severe patients during a time when resistance was rare. Nowadays there is increasing evidence that critically ill patients experiment altered pharmacokinetics (PK) that may lead to therapeutic failure and/or drug toxicity. Equally, such PK alterations are complex and challenging to investigate. Finally pharmacodynamics (PD) may also be different in this population and antibiotic targets may need to be tailored to the individual patient. The aim of this research was to investigate the relationship between antibiotic therapy, its PK and PD, bacterial burden and critically ill patients outcomes. The research plan comprised of: 1. Epidemiological portuguese data of critically ill infected patients; 2. Relationship between burden of bacteria, time until the start of antibiotics and patient outcomes; 3. Evaluation of PK during treatment of infection; 4. A multicentre study evaluating PK guided β-lactam therapy. The introductory chapter outlines the importance of antibiotics, its origins, the problem of increasing bacteria resistance, related to its use and overuse and the importance of rational drug dosing using PK and PD concepts. In Chapter 1 portuguese epidemiological data of infections in critically ill patients is presented, mostly coming from two prospective observational studies, encompassing more than 50% of critically ill beds available in Portugal. Chapter 2 describes the concepts of PK and the changes occurring in critically ill patients. This is followed by a review of the concepts of PD of antibiotics and its application to this population, especially during severe infections (Chapter 3). In the following chapter these changes in antibiotics PK in critical illness are and its causes are detailed, to outline the importance of therapeutic drug monitoring. Data on a systematic review of antibiotics PK in those patients is provided (Chapter 4). The following chapter (Chapter 5) elucidates important changes in PD, that compromises antibiotic therapy, facilitate the occurrence of resistance and may lead to therapeutic failure. Thus, an understanding of the clinical problem and available evidence facilitated the development of a comprehensive research plan (Chapter 6 and Chapter 7). Chapter 6.1 describes time-dependent antibiotics and the importance of extending its perfusion time. A multicenter study was designed to compare the continuous infusion of piperacillin tazobactam (a β-lactam antibiotic) with the same daily dose, prescribed in a conventional, intermittent dose. The importance of correct dosing of antibiotics was also assessed through a study addressing aminoglycoside (a concentration-dependent antibiotic) therapy (Chapter 6.2), focusing on its first dose. Strategies to improve severe infected patients outcomes were addressed in Chapter 7, namely the importance of early antibiotic therapy, assessing the burden of bacteria and understanding changes in antibiotic concentration during the course of infection. An algorithm to include all the described changes in both PK and PD of critically ill patients was developed. Finally in Chapter 8 mechanisms of the increasing resistance of bacteria are described and strategies to address that problem are proposed. The closing chapter (Chapter 9) lays a roadmap for future work. The key finding of this research is the significant variability of the antibiotics PK during critical illness, which makes dosing a challenging issue. These changes are related to the severity of the infection itself and improve through the course of the disease. However neither disease severity nor individual characteristics are useful to predict PK changes. Therefore, the use of a universal dose approach, regardless of the individual patient, may not be the best approach. Strategies to improve patients’ outcomes should be based on tailoring antibiotics to the individual patient, according to PK and PD principles, preferentially supported by therapeutic drug monitoring.
