Objetivo: O reconhecimento contabilístico dos ativos intangíveis tem vindo a gerar alguma controvérsia, dadas as caraterísticas particulares que lhe estão associadas: a dificuldade em identificá-los devido à sua natureza não física e a sua difícil mensuração. No entanto, a caraterística mais importante tem a ver com o grau de incerteza em relação à obtenção de benefícios económicos futuros. Estas caraterísticas fazem com que esses ativos sejam pouco considerados nas demonstrações financeiras das organizações atuais, existindo cada vez maiores exigências das partes interessadas em informação transparente e credível. O ano de 2016 ficará marcado por uma reforma nacional ao nível da contabilidade empresarial e pública. Com a publicação do Decreto-Lei n.º 98/2015, de 2 de junho, os instrumentos contabilísticos do novo Sistema de Normalização Contabilística (SNC) foram aprovados para serem aplicados a períodos que se iniciem a partir 1 de janeiro de 2016. Também a implementação do Decreto-Lei nº 192/2015, de 11 de setembro, trará para as administrações públicas uma uniformidade de procedimentos contabilísticos não existente no setor público em Portugal até então, e cuja obrigatoriedade de aplicação se reporta a 1 de janeiro de 2017. Face ao exposto, o objetivo central deste trabalho é efetuar uma análise comparativa da contabilização dos ativos intangíveis no âmbito do SNC e do SNC-AP (Sistema de Normalização Contabilística para as Administrações Públicas). Desenho/metodologia/abordagem: Investigação qualitativa através da realização de uma análise comparativa ao normativo contabilístico existente no âmbito privado (SNC) e público (SNC-AP). Resultados: A convergência dos normativos SNC e SNC-AP, no que diz respeito aos ativos intangíveis, nos critérios de reconhecimento e mensuração não é plena. No que respeita ao reconhecimento, é dada a possibilidade, no âmbito público, de um elemento ser reconhecido como ativo, mesmo que não produza benefícios económicos futuros para a entidade, desde que possua potencial de serviço. No que à mensuração se refere, na norma aplicada ao setor público o modelo da revalorização é visto como uma alternativa ao modelo do custo, não estando previsto nesse modelo o reconhecimento de perdas por imparidade. Originalidade/valor: Entendemos que as conclusões observadas neste trabalho poderão contribuir para que outros estudos se desenvolvam no âmbito de uma análise conjunta aos normativos contabilísticos adotados em Portugal. Além disso, trata-se de um estudo bastante recente, atendendo à obrigatoriedade de adoção do SNC-AP a partir de 2017.

Objetivo: Em virtude da necessidade de comparabilidade da informação financeira das entidades públicas dos diferentes países Europeus e, consequentemente, da necessidade de adoção das International Public Sector Accounting Standards (IPSAS), foi necessário proceder a uma reforma dos sistemas de Contabilidade Pública dos diferentes Estados membros da União Europeia. Desta reforma resultou a aprovação, do Sistema de Normalização Contabilística para as Administrações Públicas (SNC-AP), através do Decreto-lei nº 192/2015, de 11/9, que traz várias mudanças, nomeadamente quanto à contabilização dos ativos fixos tangíveis (AFT). Atendendo a este contexto, este trabalho tem por objetivos efetuar um estudo comparativo do definido nos normativos contabilísticos públicos (nomeadamente no Plano Oficial de Contabilidade das Autarquias Locais – POCAL e no SNC-AP) e privados (Sistema de Normalização Contabilística – SNC), quanto às principais particularidades da contabilização dos AFT, nomeadamente o seu reconhecimento e a sua mensuração. Metodologia: Na elaboração deste trabalho foi adotada uma metodologia qualitativa baseada num estudo comparativo dos normativos contabilísticos públicos (POCAL e SNC-AP) e privados (SNC), quanto ao reconhecimento e mensuração dos AFT. Originalidade: Consideramos que este trabalho é um tema original e atual, que tem por base um diploma recente (SNC-AP), cuja obrigatoriedade de aplicação apenas se estabelece para o ano de 2017, e que, por essa razão, ainda não foi muito abordado no âmbito da investigação científica. Por outro lado, este trabalho poderá contribuir para um estudo comparativo das diferentes normas, existentes em Portugal, no âmbito público e privado. Resultados: Este estudo permite concluir que o novo normativo (SNC-AP) evidencia um avanço face ao POCAL, definindo não só o conceito de ativo e de AFT, como também os critérios de reconhecimento que um elemento deve cumprir para que possa ser reconhecido como tal, permitindo assim uma maior consistência no reconhecimento destes elementos, por parte das diferentes entidades públicas. Portanto, no que respeita ao reconhecimento dos ativos o SNC-AP aproxima-se do SNC, com algumas particularidades específicas do âmbito público, como o facto de um elemento poder ser reconhecido como ativo mesmo que não produza rendimentos, desde que possua potencial de serviço. Por outro lado, relativamente à mensuração, o SNC-AP segue de perto, com as devidas adaptações, os normativos internacionais e também o SNC, introduzindo, comparativamente ao definido no POCAL, dois momentos de mensuração dos AFT, e referindo o justo valor explicitamente enquanto critério de mensuração aplicável a situações concretas, e já não apenas o tradicional custo histórico. Limitações: A atualidade do tema deste trabalho trouxe algumas limitações no que respeita à revisão de literatura de trabalhos de cariz científico, que são ainda escassos. Por outro lado, o facto do SNC-AP apenas ser de aplicação obrigatória no ano de 2017, e atualmente apenas estar a ser aplicado por algumas entidades piloto, não nos permitiu efetuar um estudo das consequências que, na prática, a adoção deste novo normativo terá, no que respeita ao reconhecimento e mensuração dos AFT.

The UK government aims at achieving 80% CO2 emission reduction by 2050 which requires collective efforts across all the UK industry sectors. In particular, the housing sector has a large potential to contribute to achieving the aim because the housing sector alone accounts for 27% of the total UK CO2 emission, and furthermore, 87% of the housing which is responsible for current 27% CO2 emission will still stand in 2050. Therefore, it is essential to improve energy efficiency of existing housing stock built with low energy efficiency standard. In order for this, a whole‐house needs to be refurbished in a sustainable way by considering the life time financial and environmental impacts of a refurbished house. However, the current refurbishment process seems to be challenging to generate a financially and environmentally affordable refurbishment solution due to the highly fragmented nature of refurbishment practice and a lack of knowledge and skills about whole‐house refurbishment in the construction industry. In order to generate an affordable refurbishment solution, diverse information regarding costs and environmental impacts of refurbishment measures and materials should be collected and integrated in right sequences throughout the refurbishment project life cycle among key project stakeholders. Consequently, various researchers increasingly study a way of utilizing Building Information Modelling (BIM) to tackle current problems in the construction industry because BIM can support construction professionals to manage construction projects in a collaborative manner by integrating diverse information, and to determine the best refurbishment solution among various alternatives by calculating the life cycle costs and lifetime CO2 performance of a refurbishment solution. Despite the capability of BIM, the BIM adoption rate is low with 25% in the housing sector and it has been rarely studied about a way of using BIM for housing refurbishment projects. Therefore, this research aims to develop a BIM framework to formulate a financially and environmentally affordable whole‐house refurbishment solution based on the Life Cycle Costing (LCC) and Life Cycle Assessment (LCA) methods simultaneously. In order to achieve the aim, a BIM feasibility study was conducted as a pilot study to examine whether BIM is suitable for housing refurbishment, and a BIM framework was developed based on the grounded theory because there was no precedent research. After the development of a BIM framework, this framework was examined by a hypothetical case study using BIM input data collected from questionnaire survey regarding homeowners’ preferences for housing refurbishment. Finally, validation of the BIM framework was conducted among academics and professionals by providing the BIM framework and a formulated refurbishment solution based on the LCC and LCA studies through the framework. As a result, BIM was identified as suitable for housing refurbishment as a management tool, and it is timely for developing the BIM framework. The BIM framework with seven project stages was developed to formulate an affordable refurbishment solution. Through the case study, the Building Regulation is identified as the most affordable energy efficiency standard which renders the best LCC and LCA results when it is applied for whole‐house refurbishment solution. In addition, the Fabric Energy Efficiency Standard (FEES) is recommended when customers are willing to adopt high energy standard, and the maximum 60% of CO2 emissions can be reduced through whole‐house fabric refurbishment with the FEES. Furthermore, limitations and challenges to fully utilize BIM framework for housing refurbishment were revealed such as a lack of BIM objects with proper cost and environmental information, limited interoperability between different BIM software and limited information of LCC and LCA datasets in BIM system. Finally, the BIM framework was validated as suitable for housing refurbishment projects, and reviewers commented that the framework can be more practical if a specific BIM library for housing refurbishment with proper LCC and LCA datasets is developed. This research is expected to provide a systematic way of formulating a refurbishment solution using BIM, and to become a basis for further research on BIM for the housing sector to resolve the current limitations and challenges. Future research should enhance the BIM framework by developing more detailed process map and develop BIM objects with proper LCC and LCA Information.

It is considered that the Strategic Alignment IT is the first step within the IT Governance process for any institution. Taking as initial point the recognition that the governance corporate has an overall view of the organizations, the IT Governance takes place as a sub-set responsible for the implementation of the organization strategies in what concerns the provision of the necessary tools for the achievement of the goals set in the Institutional Development Plan. In order to do so, COBIT specifies that such Governance shall be built on the following principles: Strategic Alignment, Value Delivery, Risk Management, Performance Measurement. This paper aims at the Strategic Alignment, considered by the authors as the foundation for the development of the entire IT Governance core. By deepening the technical knowledge of the management system development, UFRN has made a decisive step towards the technical empowerment needed to the “Value Delivery”, yet, by perusing the primarily set processes to the “Strategic Alignment”, gaps that limited the IT strategic view in the implementation of the organizational goals were found. In the qualitative study that used documentary research with content analysis and interviews with the strategic and tactical managers, the view on the role of SINFO – Superintendência de Informática was mapped. The documentary research was done on public documents present on the institutional site and on TCU – Tribunal de Contas da União – documents that map the IT Governance profiles on the federal public service as a whole. As a means to obtain the documentary research results equalization, questionnaires/interviews and iGovTI indexes, quantitative tools to the standardization of the results were used, always bearing in mind the usage of the same scale elements present in the TCU analysis. This being said, similarly to what the TCU study through the IGovTI index provides, this paper advocates a particular index to the study area – SA (Strategic Alignment), calculated from the representative variables of the COBIT 4.1 domains and having the representative variables of the Strategic Alignment primary process as components. As a result, an intermediate index among the values in two adjacent surveys done by TCU in the years of 2010 and 2012 was found, which reflects the attitude and view of managers towards the IT governance: still linked to Data Processing in which a department performs its tasks according to the demand of the various departments or sectors, although there is a commission that discusses the issues related to infrastructure acquisition and systems development. With an Operational view rather than Strategic/Managerial and low attachment to the tools consecrated by the market, several processes are not contemplated in the framework COBIT defined set; this is mainly due to the inexistence of a formal strategic plan for IT; hence, the partial congruency between the organization goals and the IT goals.

This thesis presents and discusses the results of ambient seismic noise correlation for two different environments: intraplate and Mid-Atlantic Ridge. The coda wave interferometry method has also been tested for the intraplate data. Ambient noise correlation is a method that allows to retrieve the structural response between two receivers from ambient noise records, as if one of the station was a virtual source. It has been largely used in seismology to image the subsurface and to monitor structural changes associated mostly with volcanic eruptions and large earthquakes. In the intraplate study, we were able to detect localized structural changes related to a small earthquake swarm, which main event is mR 3.7, North-East of Brazil. We also showed that the 1-bit normalization and spectral whitening result on the loss of waveform details and that the phase auto-correlation, which is amplitude unbiased, seems to be more sensitive and robust for our analysis of a small earthquake swarm. The analysis of 6 months of data using cross-correlations detect clear medium changes soon after the main event while the auto-correlations detect changes essentially after 1 month. It could be explained by fluid pressure redistribution which can be initiated by hydromechanical changes and opened path ways to shallower depth levels due to later occurring earthquakes. In the Mid-Atlantic Ridge study, we investigate structural changes associated with a mb 4.9 earthquake in the region of the Saint Paul transform fault. The data have been recorded by a single broadband seismic station located at less than 200 km from the Mid-Atlantic ridge. The results of the phase auto-correlation for a 5-month period, show a strong co-seismic medium change followed by a relatively fast post-seismic recovery. This medium change is likely related to the damages caused by the earthquake’s ground shaking. The healing process (filling of the new cracks) that lasted 60 days can be decomposed in two phases, a fast recovery (70% in ~30 days) in the early post-seismic stage and a relatively slow recovery later (30% in ~30 days). In the coda wave interferometry study, we monitor temporal changes of the subsurface caused by the small intraplate earthquake swarm mentioned previously. The method was first validated with synthetics data. We were able to detect a change of 2.5% in the source position and a 15% decrease of the scatterers’ amount. Then, from the real data, we observed a rapid decorrelation of the seismic coda after the mR 3.7 seismic event. This indicates a rapid change of the subsurface in the fault’s region induced by the earthquake.

The dissertation was divided in two studies. With the first, aimed to evaluate the occurrence of microorganisms present in the vulvovaginal region of cows that received intravaginal progesterone devices during the fixed-time artificial insemination (FTAI) programs, and correlate the results with pregnancy rates. Samples were collected from vulvovaginal region of 30 beef cows Guzerá and 30 crossbred dairy cows, and also intravaginal devices, randomly. Of the 120 samples of cows, 60 corresponded to the collections of the period prior to the introduction device (D0) and 60 to the subsequent withdrawal of it (D9); it yielded 100% of bacterial growth, whereas, in most samples, it was found more than one isolated. In D0, the most frequent agent was Escherichia coli (52%), and in D9, Proteus spp and E. coli were the most frequent (32% and 28%, respectively). Regarding intravaginal progesterone devices, in D0 were isolated 37 microorganisms, being predominant those of the genus Bacillus (35%); in D9, 41 colony forming units (CFU) were isolated, of which 36.6% corresponded to Proteus spp. For the analysis of the antimicrobial profile, susceptibility testing was performed by diffusion agar disk, and cows that did not became pregnant after FTAI program were selected, as a future treatment. There resistance 100% to penicillin, and sensitivity, approximately, 90% to gentamicin, both isolates obtained from samples of beef cows and obtained of dairy cows. Regarding pregnancy rate, the 30 beef cows, 11 were diagnosed pregnant (36.7%), 4 (36.4%) treated with reused devices and 7 (63.6%) with new devices, which showed more effective. Of the 30 dairy cows, 15 were pregnant (50%), 8 (53.3%) were implanted with reused devices and 7 (46.7%) with new devices, with no significant differences in pregnancy rates. Because it is a research, females were chosen at random, and factors such as body condition, nutritional management and health weren't priority. With the second study, aimed to analyze the similarity between strains, conducted by technical Random Amplified Polymorphic DNA (RAPD -PCR). Presence of E. coli and the absence of pregnancy were selection criteria used. From the results, it was observed that most of the isolates wasn't phylogenetically similar, since they showed lower than 85% similarity. The study stressed the importance of E. coli in vulvovaginal microbiota of cows and the presence of phenotypic and genotypic characters of this bacterium on possible reproductive problems.

O presente relatório centra-se na aplicação de um sistema de padronização numa célula de pintura industrial. Assim, e como a célula estudada não tinha no momento um sistema de padronização implementado, a principal motivação deste trabalho prendeu-se com a obtenção de benefícios que a normalização de boas práticas pode trazer aos processos, principalmente em indústrias extremamente competitivas, como é o caso do setor em que a empresa em estudo se insere. Para sustentar a implementação da padronização na célula de pintura foi primariamente realizado um estudo teórico sobre a metodologia de base: o LEAN, assim como sobre algumas das suas principais ferramentas. Em particular, destaca-se o Standard Work, ou Padronização, e a Auditoria. Fazendo uso deste levantamento bibliográfico e dos recursos presentes na empresa de acolhimento, foi assim gerado e implementado um sistema padronizado na célula de pintura, composto essencialmente por padrões de tarefas e documentação. Estes têm como principal função criar fundações de base fiável e íntegra, servindo de apoio ao controlo da qualidade, resolução de problemas, e implementação de melhorias no futuro industrial da célula visada. De modo complementar, foi também produzido um conjunto de propostas de implementações de novos métodos, incidindo principalmente na melhoria da qualidade de execução das operações de setup.

Energy efficiency and user comfort have recently become priorities in the Facility Management (FM) sector. This has resulted in the use of innovative building components, such as thermal solar panels, heat pumps, etc., as they have potential to provide better performance, energy savings and increased user comfort. However, as the complexity of components increases, the requirement for maintenance management also increases. The standard routine for building maintenance is inspection which results in repairs or replacement when a fault is found. This routine leads to unnecessary inspections which have a cost with respect to downtime of a component and work hours. This research proposes an alternative routine: performing building maintenance at the point in time when the component is degrading and requires maintenance, thus reducing the frequency of unnecessary inspections. This thesis demonstrates that statistical techniques can be used as part of a maintenance management methodology to invoke maintenance before failure occurs. The proposed FM process is presented through a scenario utilising current Building Information Modelling (BIM) technology and innovative contractual and organisational models. This FM scenario supports a Degradation based Maintenance (DbM) scheduling methodology, implemented using two statistical techniques, Particle Filters (PFs) and Gaussian Processes (GPs). DbM consists of extracting and tracking a degradation metric for a component. Limits for the degradation metric are identified based on one of a number of proposed processes. These processes determine the limits based on the maturity of the historical information available. DbM is implemented for three case study components: a heat exchanger; a heat pump; and a set of bearings. The identified degradation points for each case study, from a PF, a GP and a hybrid (PF and GP combined) DbM implementation are assessed against known degradation points. The GP implementations are successful for all components. For the PF implementations, the results presented in this thesis find that the extracted metrics and limits identify degradation occurrences accurately for components which are in continuous operation. For components which have seasonal operational periods, the PF may wrongly identify degradation. The GP performs more robustly than the PF, but the PF, on average, results in fewer false positives. The hybrid implementations, which are a combination of GP and PF results, are successful for 2 of 3 case studies and are not affected by seasonal data. Overall, DbM is effectively applied for the three case study components. The accuracy of the implementations is dependant on the relationships modelled by the PF and GP, and on the type and quantity of data available. This novel maintenance process can improve equipment performance and reduce energy wastage from BSCs operation.

This paper aims to present a state-of-the-art review of the scope and practical implications of the Building Information Modelling (BIM) platform in the UK construction practice. Theoretical developments suggest that BIM is an integration of both product and process innovation, not just a disparate set of software tools. BIM provides effective collaboration, visual representation and data management, which enable the smooth flow of information throughout the project’s lifecycle. The most frequently reported benefits are related to Capital Cost (capex) and Operational costs (opex) and time savings. Key challenges, however, focus on the interoperability of software, capital installation costs, in-house experience, client preference and cultural issues within design teams and within the organisation. The paper concludes with a critical commentary on the changing roles and a process required to implement BIM in UK construction projects, and suggests areas for further research.

O Serviço Social Escolar é um campo de acção que ao longo de quase 40 anos tem uma trajectória significativa, tendo sofrido algumas vicissitudes no seu percurso influenciado pelo contexto social político e económico e pelas relações Estado/Mercado. Este estudo vai no sentido de fazer uma análise ao processo de institucionalização do Serviço Social Escolar em Portugal nas décadas de 60 e 70, em que se privilegiam as trajectórias e dinâmicas da prática profissional das Assistentes Sociais na área da Educação, ao nível dos ensinos primários, preparatórios e secundários, e mais especificamente da prática profissional das Assistentes Sociais do Ministério da Educação, da Zona Centro do País. Está dividido em duas partes fundamentais, acompanhando a primeira de1960 até 1974 e a segunda parte após o período da Revolução de 25 de Abril de 1974 até ao período de Normalização Democrática de 1976 a 1980. Procura-se apreender e compreender a relação entre o Serviço Social, políticas sociais, de acção social escolar, a sociedade portuguesa, as correntes de pensamento e as influências que se fizeram sentir no Serviço Social Escolar, identificando problemas e posicionamentos das Assistentes Sociais na dinâmica sócio-histórico e no Instituto de Acção Social Escolar, nos períodos em análise. Com este trabalho pretende-se abrir o debate sobre este campo de acção na actualidade e restituir ao Serviço Social Escolar o papel fundamental de mediador nos processos de regulação no campo da educação, num trabalho em parceria e numa transversalidade de competências e saberes com todos os parceiros da comunidade educativa e com a sociedade em geral, na defesa pelos direitos humanos e ampliação do estatuto de cidadania, por uma escola para todos e de qualidade.
