Os Coveiros enquanto Recursos Humanos

A presente dissertação consiste num trabalho de investigação, descritivo e exploratório, cujo objetivo é o estudo da profissão de coveiro no universo dos recursos humanos - a sua profissão, formação, sentimentos e perspetiva inerente ao novo paradigma da cremação. Começou por se abordar as dificuldades surgidas durante a elaboração do trabalho e que, fundamentalmente, se relacionavam com a falta de informação e o tabu e preconceito social que o tema da morte ainda provoca na sociedade atual. Seguidamente, elaborou-se um enquadramento teórico e histórico sobre o nascimento dos cemitérios, baseado em referências bibliográficas, com o intuito de melhor compreender a necessidade da existência da profissão de coveiro. Posteriormente, foi realizada uma análise cuidada e rigorosa aos dados recolhidos durante o trabalho de investigação, abordando os aspetos qualitativos e demográficos para, deste modo, se proceder à caraterização do perfil do coveiro, enquanto profissional. Recolheram-se opiniões junto da hierarquia (chefias) e dos clientes (famílias dos defuntos), de forma a construir uma ideia mais coesa da profissão de coveiro. Para a um melhor entendimento da atividade profissional em estudo, realizou-se ainda uma entrevista aos responsáveis da Servilusa, entidade formadora neste sector, aprofundando deste modo, as boas práticas e se perceber como funciona este setor de atividade terciária. Solicitaram-se esclarecimentos aos responsáveis dos Alcoólicos Anónimos (AA), com o intuito de aprofundar os conhecimentos em torno do problema do alcoolismo nesta profissão, de forma a opinar sobre esta matéria de uma maneira mais rigorosa e responsável. Realizou-se ainda uma abordagem sobre a cremação como um novo paradigma que poderá, de certo modo, pôr em causa o futuro da função do coveiro e respetiva categoria profissional. Como conclusão, sugeriram-se soluções que visam a melhoria da situação profissional dos coveiros, do seu bem-estar e condições de trabalho, tendo o presente trabalho culminado com a criação de um código de ética, na implementação da avaliação de desempenho, atribuição da carreira de coveiro e respetivas categorias, assim como na atualização de conhecimentos e melhoria de competências profissionais e pessoais, com o recurso à formação profissional.

A Gestão Documental na Autoridade Portuária de Barcelona

Este relatório de estágio representa o trabalho desenvolvido na Autoritat Portuària de Barcelona (APB), mais precisamente no Centro de Documentação da Autoridade Portuária de Barcelona, num período de 150 horas, onde tive a oportunidade de passar pelos diferentes serviços de documentação e realizar as tarefas inerentes a uma Instituição com idêntica tipologia àquela onde presto idêntica atividade em Portugal. Descreve-se a empresa e o trabalho desenvolvido no Centro de Documentação (CENDOC), considerando todas as funções desenvolvidas ao nível da gestão documental, na biblioteca, no arquivo intermédio, histórico e no arquivo fotográfico. O serviço de Arquivo agiliza a gestão de um fundo documental com mais de 3.900 metros lineares de documentos textuais, 500 metros lineares de documentação gráfica e cartográfica e 75.000 fotografias. Também gere o Património Cultural Móvel da APB, tanto o fundo documental do Arquivo Histórico (textual e imagens), como as coleções de objetos artísticos de interesse histórico e cultural (pinturas, esculturas, artes decorativas, cartas náuticas, modelos de navios). Toda a documentação do Arquivo Intermédio foi devidamente tratada, higienizada e organizada num novo espaço de arquivo, com melhores condições de acondicionamento. Aproveitando este trabalho, foi desenvolvido um novo Plano de Classificação em maio de 2012, no mesmo período que desenvolvi o estágio, a fim de melhorar o serviço de Arquivo.

Enquanto Técnica Superior no Centro de Documentação e Informação na Administração do Porto de Lisboa (APL), o desenvolvimento deste estágio trouxe um importante contributo para o serviço que desempenho no Centro de Documentação e Informação na Administração do Porto de Lisboa. Este Estágio possibilitou, sem dúvida, um melhor conhecimento teórico e prático no âmbito das tarefas inerentes ao mesmo, e a capacitação para o desenvolvimento de projetos relacionados com as funções que desempenho, no Centro de Documentação e Informação da Administração do Porto de Lisboa.

Moving on. Where should the university map collection be going?

This paper argues for the importance of retaining a map library presence on UK university campuses at a time when many are under threat of closure, and access to geospatial data is increasingly moving to web-based services. It is suggested that the need for local expertise is undiminished and map curators need to redefine themselves as geoinformation specialists, preserving their paper map collections, but also meeting some of the challenges of GIS, and contributing to national developments in the construction of distributed geolibraries and the provision of metadata, especially with regard to local data sets.

Design and formative evaluation of an information kiosk on cattle health for landless cattle owners

This paper describes and analyses the experience of designing, installing and evaluating a farmer-usable touch screen information kiosk on cattle health in a veterinary institution in Pondicherry. The contents of the kiosk were prepared based on identified demands for information on cattle health, arrived at through various stakeholders meetings. Information on these cattle diseases and conditions affecting the livelihoods of the poor was provided through graphics, text and audio back-up, keeping in mind the needs of landless and illiterate poor cattle owners. A methodology for kiosk evaluation based on the feedback obtained from kiosk facilitator, critical group reflection and individual users was formulated. The formative evaluation reveals the potential strength this ICT has in transferring information to the cattle owners in a service delivery centre. Such information is vital in preventing diseases and helps cattle owners to present and treat their animals at an early stage of disease condition. This in turn helps prevent direct and indirect losses to the cattle owners. The study reveals how an information kiosk installed at a government institution as a freely accessible source of information to all farmers irrespective of their class and caste can help in transfer of information among poor cattle owners, provided periodic updating, interactivity and communication variability are taken care of. Being in the veterinary centre, the kiosk helps stimulate dialogue, and facilitates demand of services based on the information provided by the kiosk screens.

Learning from risks: A tool for post-project risk assessment

Risk management (RM) comprises of risk identification, risk analysis, response planning, monitoring and action planning tasks that are carried out throughout the life cycle of a project in order to ensure that project objectives are met. Although the methodological aspects of RM are well-defined, the philosophical background is rather vague. In this paper, a learning-based approach is proposed. In order to implement this approach in practice, a tool has been developed to facilitate construction of a lessons learned database that contains risk-related information and risk assessment throughout the life cycle of a project. The tool is tested on a real construction project. The case study findings demonstrate that it can be used for storing as well as updating risk-related information and finally, carrying out a post-project appraisal. The major weaknesses of the tool are identified as, subjectivity of the risk rating process and unwillingness of people to enter information about reasons of failure.

The psychological, neurochemical and functional neuroanatomical mediators of the effects of positive and negative mood on executive functions

In this review we evaluate the cognitive and neural effects of positive and negative mood on executive function. Mild manipulations of negative mood appear to have little effect on cognitive control processes, whereas positive mood impairs aspects of updating, planning and switching. These cognitive effects may be linked to neurochemistry: with positive mood effects mediated by dopamine while negative mood effects may be mediated by serotonin levels. Current evidence on the effects of mood on regional brain activity during executive functions, indicates that the prefrontal cortex is a recurrent site of integration between mood and cognition. We conclude that there is a disparity between the importance of this topic and awareness of how mood affects, executive functions in the brain. Most behavioural and neuroimaging studies of executive function in normal samples do not explore the potential role of variations in mood, yet the evidence we outline indicates that even mild fluctuations in mood can have a significant influence on neural activation and cognition.

An Agent Based Education Resource Purvey System

Most current education organizations use books and CDs as the main media, which takes a long time for knowledge updating between education resource providers and the users. The rapid development of the Internet has brought with it the possibility of improving the resource purveying mechanisms. Therefore, we designed an agent based system to purvey education resources from the resource centre to schools through the Internet. Agent technology helps to improve system performance and flexibility. This paper describes the design of our system, details the functions of the main parts of the system, shows the communication methods between agents and finally evaluates the system by experiments.

A kernel-based two-class classifier for imbalanced data sets

Many kernel classifier construction algorithms adopt classification accuracy as performance metrics in model evaluation. Moreover, equal weighting is often applied to each data sample in parameter estimation. These modeling practices often become problematic if the data sets are imbalanced. We present a kernel classifier construction algorithm using orthogonal forward selection (OFS) in order to optimize the model generalization for imbalanced two-class data sets. This kernel classifier identification algorithm is based on a new regularized orthogonal weighted least squares (ROWLS) estimator and the model selection criterion of maximal leave-one-out area under curve (LOO-AUC) of the receiver operating characteristics (ROCs). It is shown that, owing to the orthogonalization procedure, the LOO-AUC can be calculated via an analytic formula based on the new regularized orthogonal weighted least squares parameter estimator, without actually splitting the estimation data set. The proposed algorithm can achieve minimal computational expense via a set of forward recursive updating formula in searching model terms with maximal incremental LOO-AUC value. Numerical examples are used to demonstrate the efficacy of the algorithm.

A fast linear-in-the-parameters classifier construction algorithm using orthogonal forward selection to minimize leave-one-out misclassification rate

We propose a simple and computationally efficient construction algorithm for two class linear-in-the-parameters classifiers. In order to optimize model generalization, a forward orthogonal selection (OFS) procedure is used for minimizing the leave-one-out (LOO) misclassification rate directly. An analytic formula and a set of forward recursive updating formula of the LOO misclassification rate are developed and applied in the proposed algorithm. Numerical examples are used to demonstrate that the proposed algorithm is an excellent alternative approach to construct sparse two class classifiers in terms of performance and computational efficiency.

Probability density estimation with tunable kernels using orthogonal forward regression

A generalized or tunable-kernel model is proposed for probability density function estimation based on an orthogonal forward regression procedure. Each stage of the density estimation process determines a tunable kernel, namely, its center vector and diagonal covariance matrix, by minimizing a leave-one-out test criterion. The kernel mixing weights of the constructed sparse density estimate are finally updated using the multiplicative nonnegative quadratic programming algorithm to ensure the nonnegative and unity constraints, and this weight-updating process additionally has the desired ability to further reduce the model size. The proposed tunable-kernel model has advantages, in terms of model generalization capability and model sparsity, over the standard fixed-kernel model that restricts kernel centers to the training data points and employs a single common kernel variance for every kernel. On the other hand, it does not optimize all the model parameters together and thus avoids the problems of high-dimensional ill-conditioned nonlinear optimization associated with the conventional finite mixture model. Several examples are included to demonstrate the ability of the proposed novel tunable-kernel model to effectively construct a very compact density estimate accurately.

An LMS style variable tap-length algorithm for structure adaptation

Searching for the optimum tap-length that best balances the complexity and steady-state performance of an adaptive filter has attracted attention recently. Among existing algorithms that can be found in the literature, two of which, namely the segmented filter (SF) and gradient descent (GD) algorithms, are of particular interest as they can search for the optimum tap-length quickly. In this paper, at first, we carefully compare the SF and GD algorithms and show that the two algorithms are equivalent in performance under some constraints, but each has advantages/disadvantages relative to the other. Then, we propose an improved variable tap-length algorithm using the concept of the pseudo fractional tap-length (FT). Updating the tap-length with instantaneous errors in a style similar to that used in the stochastic gradient [or least mean squares (LMS)] algorithm, the proposed FT algorithm not only retains the advantages from both the SF and the GD algorithms but also has significantly less complexity than existing algorithms. Both performance analysis and numerical simulations are given to verify the new proposed algorithm.

Optimal control of nonlinear systems represented by differential algebraic equations

An iterative procedure is described for solving nonlinear optimal control problems subject to differential algebraic equations. The procedure iterates on an integrated modified simplified model based problem with parameter updating in such a manner that the correct solution of the original nonlinear problem is achieved.

Optimal control of nonlinear differential algebraic equation systems

A novel iterative procedure is described for solving nonlinear optimal control problems subject to differential algebraic equations. The procedure iterates on an integrated modified linear quadratic model based problem with parameter updating in such a manner that the correct solution of the original non-linear problem is achieved. The resulting algorithm has a particular advantage in that the solution is achieved without the need to solve the differential algebraic equations . Convergence aspects are discussed and a simulation example is described which illustrates the performance of the technique. 1. Introduction When modelling industrial processes often the resulting equations consist of coupled differential and algebraic equations (DAEs). In many situations these equations are nonlinear and cannot readily be directly reduced to ordinary differential equations.

Valuation accuracy: reconciling the timing of the valuation and sale

Carsberg (2002) suggested that the periodic valuation accuracy studies undertaken by, amongst others, IPD/Drivers Jonas (2003) should be undertaken every year and be sponsored by the RICS, which acts as the self-regulating body for valuations in the UK. This paper does not address the wider issues concerning the nature of properties which are sold and whether the sale prices are influenced by prior valuations, but considers solely the technical issues concerning the timing of the valuation and sales data. This study uses valuations and sales data from the Investment Property Databank UK Monthly Index to attempt to identify the date that sale data is divulged to valuers. This information will inform accuracy studies that use a cut-off date as to the closeness of valuations to sales completion date as a yardstick for excluding data from the analysis. It will also, assuming valuers are informed quickly of any agreed sales, help to determine the actual sale agreed date rather than the completion date, which includes a period of due diligence between when the sale is agreed and its completion. Valuations should be updated to this date, rather than the formal completion date, if a reliable measure of valuation accuracy is to be determined. An accuracy study is then undertaken using a variety of updating periods and the differences between the results are examined. The paper concludes that the sale only becomes known to valuers in the month prior to the sale taking place and that this assumes either that sales due diligence procedures are shortening or valuers are not told quickly of agreed sale prices. Studies that adopt a four-month cut-off date for any valuations compared to sales completion dates are over cautious, and this could be reduced to two months without compromising the data.
