Spatial analysis of crime evolution in Portugal between 1995 and 2013

The main objective of this survey was to perform descriptive analysis of crime evolution in Portugal between 1995 and 2013. The main focus of this survey was to analyse spatial crime evolution patterns in Portuguese NUTS III regions. Most important crime types have been included into analysis. The main idea was to uncover relation between local patterns and global crime evolution; to define regions which have contributed to global crime evolution of some specific crime types and to define how they have contributed. There were many statistical reports and scientific papers which have analysed some particular crime types, but one global spatial-temporal analysis has not been found. Principal Component Analysis and multidimensional descriptive data analysis technique STATIS have been the base of the analysis. The results of this survey has shown that strong spatial and temporal crime patterns exist. It was possible to describe global crime evolution patterns and to define crime evolution patterns in NUTS III regions. It was possible to define three to four groups of crimes where each group shows similar spatial crime dynamics.

A Classificação Internacional de Funcionalidade, Incapacidade e Saúde : um modelo multidimensional e multideterminado da funcionalidade em idosos assistidos na Rede

RESUMO: Os estudos sobre a funcionalidade da população idosa têm uma representação importante naquilo que é o atual conhecimento da demografia do mundo. Portugal posiciona-se e perspetiva-se como pertencendo aos países mais envelhecidos, possuindo uma rede de cuidados pós-agudos – a Rede Nacional de Cuidados Continuados Integrados (RNCCI)– que assiste uma parcela importante dessa população. Os aspetos conceptuais da funcionalidade de acordo com a OMS e operacionalizados pela Classificação Internacional de Funcionalidade (CIF), não mereceram até agora suficiente aplicabilidade no nosso país, inviabilizando a possibilidade de oferecermos contributos para a sua operacionalização. Da mesma forma, também os Core Sets da Classificação não têm sido sujeitos a processos de validação que contemplem amostras portuguesas, mantendo-se desconhecimento da especificidade dos fatores contextuais na nossa população. O presente estudo tem como objetivos conhecer a evolução da funcionalidade dos idosos assistidos na RNCCI na região do Algarve nas unidades de convalescença e média duração, validar o Core Set Geriátrico da OMS e propor uma versão abreviada da sua modalidade abrangente, no contexto destes cuidados. A amostra constituída por 451 idosos, dos quais 62,1% eram mulheres, revelou na pré-morbilidade níveis favoráveis de funcionalidade, com exceção para as Atividades Domésticas. Contudo, os mais idosos (≥ 85 anos), os indivíduos sem escolaridade, as mulheres e os viúvos/solteiros apresentaram mais casos desfavoráveis quando comparados com os seus pares. Na evolução da funcionalidade observámos melhorias significativas em todos os domínios avaliados, com diferenças relativamente à idade e à escolaridade; apesar dos resultados positivos os mais idosos e os indivíduos sem escolaridade apresentaram níveis inferiores de evolução. No entanto, a funcionalidade alcançada revelou ficar com resultados significativamente inferiores na comparação com aquela que os indivíduos possuíam na pré-morbilidade. Os modelos de regressão revelaram que as Funções Mentais, a Perceção do Estado de Saúde e a atividade Usar o Telefone, foram as variáveis que melhor explicaram os outcomes da funcionalidade alcançada. A validação do Core Set Geriátrico foi possível na maioria das categorias, sendo que foi no componente das Funções do Corpo onde esse processo revelou maior fragilidade. As Funções Neuromusculoesqueléticas e Relacionadas com o Movimento foram aquelas que registaram em ambos os momentos avaliativos frequências mais elevadas de deficiência, enquanto no componente Atividades & Participação isso ocorreu na atividade Utilização dos Movimentos Finos da Mão. Os capítulos Apoios e Relacionamentos e Atitudes foram considerados os Fatores Ambientais mais Facilitadores mas também com maior impacto Barreira. A proposta para o Core Set Geriátrico Abreviado resultou das categorias independentes que explicaram os modelos da funcionalidade alcançada e cujo resultado engloba um conjunto de 27 categorias, com um enfoque importante no componente Atividades/Participação de onde se destacam os domínios da Mobilidade e dos Auto Cuidados. A funcionalidade dos indivíduos e das populações deve ser considerada uma variável incontornável da Saúde Pública, cuja avaliação deve refletir uma abordagem biopsicossocial, apoiada na Classificação Internacional de Funcionalidade. A operacionalização da Classificação a partir dos Core Sets necessita de pesquisa mais aprofundada relativamente às caraterísticas psicométricas dos seus qualificadores e dos seus processos de validação.-----------ABSTRACT: The studies about the functioning of the elderly play an important role on what the present knowledge of the demography in the world is. Portugal figures high on the most aged countries, having a network of post-acute care - the National Network of Integrated Continuous Care (RNCCI) - which assists a large part of that population. The conceptual aspects of functioning according to WHO and operated by the International Classification of Functioning (ICF), have been insufficiently addressed concerning its adequate applicability in our country, hindering the contributions of its operation. In the same way, also the Core Sets of the Classification have not been subjected to validation procedures that include portuguese samples, keeping the unawareness of specificity of the contextual factors in our population. The objectives of the present study were to know the evolution of the functioning of the elderly assisted in the RNCCI in the Algarve region in units of convalescence and average duration, validate the WHO Geriatric Core Set and propose an abridged version of this comprehensive core set in this healthcare context. The sample was composed by 451 elderly people, of which 62.1% were women, they showed favourable levels in functioning in the pre-morbid state, except for Domestic Activities. However, the oldest (≥ 85 years), the individuals with no education, women and widowed/ unmarried showed more unfavourable cases when compared to their peers. In the evolution of functioning we observed significant improvements in all domains assessed, with diferences with respect to age and education. In spite of positive results, the oldest and the individuals with no education showed lower levels of evolution. However, the functioning achieved showed significantly lower results when compared to the those observed in pre-morbidity state. Regression models reveal that Mental Functions, the Perceived Health Status and the Use of the Phone activity, were the variables that better explain the functioning of the outcomes achieved. The validation of the Geriatric Core Set of ICF was possible in most categories, and Body Functions was the component where this process showed greatest weakness. Neuromusculoskeletal and Movement-Related Functions experienced in both evaluation times with higher rates of disability, while in the Activities & Participation component this occurred in the Fine Hand Use activity. The Support and Relationships and Attitudes chapters were considered the Environmental Factors most Facilitators but also with greater impact Barrier. The proposal for the Brief Geriatric Core Set has resulted from the independent categories that explained the regression models of functioning and includes a set of 27 categories, with na important emphasis on Activities & Participation component where we can highlight the areas of Mobility and Self Care domains. The functioning of individuals and populations should be considered as an unavoidable variable of Public Health, of which the assessment should reflect a biopsychosocial approach, based on the International Classification of Functioning. The operationalization of the Classification from the Core Sets requires further research regarding the psychometric characteristics of their qualifiers and their validation procedure.

An integrated approach to Physcomitrella patens transcriptomics reveals importantclues of the evolutionary development of plant organs and sexual reproduction

Land plant evolution required the generation of a new body plan that could resist the harsher and fluctuating environmental conditions found outside of aquatic environments. Unraveling the genetic basis of plant developmental innovations is not only revealing in terms of an evolutionary point of view, but it is also important for understanding the emergence of agronomically important traits. Comparative genetic studies between basal and modern land plants, both at the genome and trancriptome levels, can help in the generation of hypotheses related to the genetic basis of plant evolutionary development.(...)

Genomic and environmental factors influence Wolbachia-Drosophila symbiosis

Intracellular, vertically transmitted bacteria form complex and intimate relationships with their hosts. Wolbachia, maternally transmitted α- proteobacteria, live within the cells of numerous arthropod species. Wolbachia are famous master manipulators of insect reproduction: to favour their own spread they can induce male killing, parthenogenesis or cytoplasmic incompatibility. Wolbachia can also protect various insects from pathogens, which makes them a promising tool for the control of vector-borne diseases. Mosquitoes with Wolbachia have already been released in the wild to eliminate dengue. Yet, how Wolbachia manipulate their hosts remains largely unknown.(...)

Evolution of reputation in networks: A mean field game approach

This work models the competitive behaviour of individuals who maximize their own utility managing their network of connections with other individuals. Utility is taken as a synonym of reputation in this model. Each agent has to decide between two variables: the quality of connections and the number of connections. Hence, the reputation of an individual is a function of the number and the quality of connections within the network. On the other hand, individuals incur in a cost when they improve their network of contacts. The initial value of the quality and number of connections of each individual is distributed according to an initial (given) distribution. The competition occurs over continuous time and among a continuum of agents. A mean field game approach is adopted to solve the model, leading to an optimal trajectory for the number and quality of connections for each individual.

Relationship between national culture, democracy and environmental performance: A panel data analysis

This paper demonstrates the significance of culture in examining the relationshipbetween democratic capital and environmental performance.The aim is to examine the relationship among scores on the Environmental Performance Index and the two dimensions of cross cultural variation suggested by Ronald Inglehart and Christian Welzel. Significantional interrelationships among democracy, cultural and environmental sustaintability measures could be found, following the regression results. Firstly, higher levels of democratic capital stock are associated with better environmental performance. Secondly importance to distinguish between cultural groups could be confirmed.

Evolution of Teeth and Quadrate in Non-avian Theropoda (Dinosauria: Saurischia), with the Description of Torvosaurus Remains from Portugal

Theropods form a highly successful and morphologically diversified group of dinosaurs that gave rise to birds. They include most, if not all, carnivorous dinosaurs, yet many theropod clades were secondarily adapted to piscivory, omnivory and herbivory, and theropods show a large array of skull and dentition morphologies. This work aims to investigate aspects of the evolution of theropod dinosaurs by analyzing in detail both the anatomy and ontogeny of teeth and quadrates in non-avian theropods, and by studying embryonic and adult material of a new species of theropod. A standardized list of terms and notations for each anatomical entity of the tooth, quadrate, and maxilla is here proposed with the goal of facilitating descriptions of these important cranial and dental elements. The distribution of thirty dental characters among 113 theropod taxa is investigated, and a list of diagnostic dental characters is proposed. As an example, four isolated theropod teeth from the Lourinhã Formation (Kimmeridgian‒Tithonian) of Portugal are described and identified based on a cladistic analysis performed on a data matrix of 141 dentition-based characters coded in 60 taxa. Two shed teeth are referred to an abelisaurid, providing the first record of Abelisauridae in the Jurassic of Laurasia and the one of the oldest records of this clade in the world, suggesting a possible radiation of Abelisauridae in Europe well before the Upper Cretaceous. The consensus tree resulting from this phylogenetic analysis, the most extensive on theropod teeth, indicates that theropod teeth provide reliable data for identification at approximately family level, and this method will help identifying theropod teeth with more confidence. A detailed description of the dentition of Megalosauridae is also provided, and a discriminant analysis performed on a dataset of numerical data collected on the teeth of 62 theropod taxa reveals that megalosaurid teeth are hardly distinguishable from other theropod clades with ziphodont dentition. This study highlights the importance of detailing anatomical descriptions and providing additional morphometric data on teeth with the purpose of helping to identify isolated theropod teeth. In order to evaluate the phylogenetic potential and investigate the evolutionary transformations of the quadrate, a phylogenetic morphometric analysis as well as a cladistic analysis using 98 discrete quadrate related characters were conducted. The quadrate morphology by its own provides a wealth of data with strong phylogenetic signal, and the phylogenetic morphometric analysis reveals two main morphotypes of the mandibular articulation of the quadrate linked to function. As an example, six isolated quadrates from the Kem Kem beds (Cenomanian) of Morocco are determined to be from juvenile and adult individuals of Spinosaurinae based on phylogenetic, morphometric, and phylogenetic morphometric analyses. Morphofunctional analysis of the spinosaurid mandibular articulation has shown that the posterior parts of the two mandibular rami displaced laterally when the jaw was depressed due to a mediolaterally oriented intercondylar sulcus of the quadrate. Such lateral movement of the mandibular ramus was possible due to a movable mandibular symphysis in spinosaurids, allowing the pharynx to be widened. A new species of theropod from the Lourinhã Formation of Portugal, Torvosaurus gurneyi, is erected based on a right maxilla and an incomplete caudal centrum. This taxon supports the mechanism of vicariance that occurred in the Iberian Meseta during the Late Jurassic when the proto-Atlantic was already well formed. A theropod clutch containing several crushed eggs and embryonic material is also assigned to this new species of Torvosaurus. Investigation on the maxilla ontogeny in basal tetanurans reveals that crown denticles, elongation of the anterior ramus, and fusion of interdental plates appear at a posthatchling stage. On the other hand, maxillary pneumaticity is already present at an embryonic stage in non-avian theropods.

Compaction quality control on site of earthworks - A comparative study

The capacity to use geologic materials (soil and rock) that are available in the surrounding environment is inherent to the human civilization and has contributed to the evolution of societies throughout the course of history. The use of these materials in the construction of structures such as houses, roads, railways or dams, stirred the improvement of socioeconomic and environmental conditions. Several reports of structural problems on embankments can be found throughout history. A considerable number of those registers can be linked to inadequate compaction, demonstrating the importance of guaranteeing a suitable quality of soil compaction. Various methodologies and specifications of compaction quality control on site of earthworks, based on the fill moisture content and dry unit weight, were developed during the 20th century. Two widely known methodologies are the conventional and nuclear techniques. The conventional methods are based on the use of the field sand cone test (or similar) and sampling of material for laboratory-based testing to evaluate the fill dry unit weight and water content. The nuclear techniques measure both parameters in the field using a nuclear density gauge. A topic under discussion in the geotechnical community, namely in Portugal, is the comparison between the accuracy of the nuclear gauge and sand cone test results for assessing the compaction and density ratio of earth fills, particularly for dams. The main purpose of this dissertation is to compare both of them. The data used were acquired during the compaction quality control operations at the Coutada/Tamujais dam trial embankment and core construction. This is a 25 m high earth dam located in Vila Velha de Rodão, Portugal. To analyse the spatial distribution of the compaction parameters (water content and compaction ratio), a 3D model was also developed. The main results achieved are discussed and finally some considerations are put forward on the suitability of both techniques to ensure fill compaction quality and on additional research to complement the conclusions obtained.

Impact of chromossomal structure on the evolution of Schizosaccharomyces pombe undergoing Mutation Accumulation

Large chromosomal rearrangements are common in natural populations and thought to be involved in speciation events. In this project, we used experimental evolution to determine how the speed of evolution and the type of accumulated mutations depend on the ancestral chromosomal structure and genotype. We utilized two Wild Type strains and a set of genetically engineered Schizosaccharomyces pombe strains, different solely in the presence of a certain type of chromosomal variant (inversions or translocations), along with respective controls. Previous research has shown that these chromosomal variants have different fitness levels in several environments, probably due to changes in the gene expression along the genome. These strains were propagated in the laboratory at very low population sizes, in which we expect natural selection to be less efficient at purging deleterious mutations. We then measured these strains’ changes in fitness throughout this accumulation of deleterious mutations, comparing the evolutionary trajectories in the different rearrangements to understand if the chromosomal structure affected the speed of evolution. We also tested these mutations for possible epistatic effects and estimated their parameters: the number of arising deleterious mutations per generation (Ud) and each one’s mean effect (sd).

Electrokinetic treatment of environmental matrices. Contaminants removal and phosphorus recovery

There is a need to develop viable techniques for removal and recovery organic and inorganic compounds from environmental matrices, due to their ecotoxicity, regulatory obligations or potential supplies as secondary materials. In this dissertation, electro –removal and –recovery techniques were applied to five different contaminated environmental matrices aiming phosphorus (P) recovery and/or contaminants removal. In a first phase, the electrokinetic process (EK) was carried out in soils for (i) metalloids and (ii) organic contaminants (OCs) removal. In the case of As and Sb mine contaminated soil, the EK process was additionally coupled with phytotechnologies. In a second phase, the electrodialytic process (ED) was applied to wastes aiming P recovery and simultaneous removal of (iii) toxins from membrane concentrate, (iv) heavy metals from sewage sludge ash (SSA), and (v) OCs from sewage sludge (SS). EK enhanced phytoremediation showed to be viable for the remediation of soils contaminated with metalloids, as although remediation was low, it combines advantages of both technologies while allowing site management. EK also proved to be an effective remediation technology for the removal and degradation of emerging OCs from two types of soil. Aiming P recovery and contaminants removal, different ED cell set-ups were tested. For the membrane concentrates, the best P recovery was achieved in a three compartment (3c) cell, but the highest toxin removal was obtained in a two compartment (2c) cell, placing the matrix in the cathode end. In the case of SSA the best approach for simultaneous P recovery and heavy metals removal was to use a 2c-cell placing the matrix in the anode end. However, for simultaneous P recovery and OCs removal, SS should be placed in the cathode end, in a 2c-cell. Overall, the data support that the selection of the cell design should be done case-by-case.

Technological evolution

The evolution of a technology and the understanding of the moment in its life cycle is of the utmost importance to the entry strategy devised by any company. Having the entry of EDP Brazil on the micro-generation market as background, the present workproject attempts to summarize the most important topics in management literature concerning the theory of technology life-cycles and the updated literature on developments of photovoltaic technology to infer the current positioning of this technology in the theoretical models. The need for this type of work stems from the very common lack of bridging between the academic research of economic aspects relevant to the evolution of technologies and the agents of research on specific technological issues. When this occurs, namely due to the external nature of research to companies, thereby escaping the harsh economic controls of a profit seeking enterprise, the evolution many times lacks the appropriate framework to be studied on a more forward looking manner and to allow for management decisions to be based on.

Developmental and paleontological insights into skull bone homology and evolution

The Gallus gallus (chicken) embryo is a central model organism in evolutionary developmental biology. Its anatomy and developmental genetics have been extensively studied and many relevant evolutionary implications have been made so far. However, important questions regarding the developmental origin of the chicken skull bones are still unresolved such that no solid homology can be established across organisms. This precludes evolutionary comparisons between this and other avian model systems in which skull anatomy has evolved significantly over the last millions of years.(...)
