Gestão de projectos de tradução e de localização - do conceito ao modelo

O crescimento do mercado electrónico e o aumento das comunicações além-fronteiras, resultante sobretudo da difusão da Internet, repercutiu-se, de modo intenso, na indústria de tradução, particularmente, na exigência crescente da tradução de websites, e, sobretudo, na localização de software. Para melhor perceber esta realidade e, de modo a contribuir para uma maior sistematização do conhecimento nesta área, o presente artigo inicia-se com uma breve análise sobre a evolução dos conceitos e dos mercados da tradução e da localização. Procura distinguir entre os diferentes prestadores de serviços de tradução, nomeadamente, empresas e agências e descreve o processo seguido na elaboração de projectos de localização, reconhecendo a tradução como elemento integrante do projecto de localização. Com base na interpretação dos conceitos de projecto e de gestão de projectos descreve-se o processo de gestão de projectos de tradução. Sendo o gestor de projectos o elemento essencial deste processo, analisam-se as funções e competências do mesmo e descrevem-se as tarefas e processos usados por este profissional, tendo em conta o ciclo de vida e os elementos que compõem o processo de gestão de projectos. A partir desta análise propõe-se um modelo de gestão de projectos de tradução/localização baseado na conjugação dos diferentes elementos afectos à gestão e ao gestor de projectos e que procura sintetizar todo o processo inerente à gestão de projectos de tradução/localização. O modelo resulta de dois pontos de vista que se interligam: o da análise e reflexão sobre o estado-da-arte e o da análise empírica dos dados recolhidos no dia-a-dia no universo de trabalho de uma empresa de tradução. Com este modelo, que retrata um processo cíclico e dinâmico, pretende-se, por um lado, ilustrar a complexidade do processo da gestão de projectos e demonstrar a importância das funções do gestor de projectos no vasto universo que é o da tradução e, por outro, desenvolver e propor um modelo de gestão de projectos aplicável a empresas de tradução e de localização.

Accounting for the dissociating properties of organic chemicals in LCIA: an uncertainty analysis applied to micropollutants in the assessment of freshwater ecotoxicity

In life cycle impact assessment (LCIA) models, the sorption of the ionic fraction of dissociating organic chemicals is not adequately modeled because conventional non-polar partitioning models are applied. Therefore, high uncertainties are expected when modeling the mobility, as well as the bioavailability for uptake by exposed biota and degradation, of dissociating organic chemicals. Alternative regressions that account for the ionized fraction of a molecule to estimate fate parameters were applied to the USEtox model. The most sensitive model parameters in the estimation of ecotoxicological characterization factors (CFs) of micropollutants were evaluated by Monte Carlo analysis in both the default USEtox model and the alternative approach. Negligible differences of CFs values and 95% confidence limits between the two approaches were estimated for direct emissions to the freshwater compartment; however the default USEtox model overestimates CFs and the 95% confidence limits of basic compounds up to three orders and four orders of magnitude, respectively, relatively to the alternative approach for emissions to the agricultural soil compartment. For three emission scenarios, LCIA results show that the default USEtox model overestimates freshwater ecotoxicity impacts for the emission scenarios to agricultural soil by one order of magnitude, and larger confidence limits were estimated, relatively to the alternative approach.

A sustentabilidade e o ciclo de vida dos edifícios

A crescente preocupação que envolve as questões ambientais a nível mundial, cada vez mais agravadas pelo comportamento irresponsável do Homem, conduziu à criação de métodos de avaliação dos impactes ambientais provocados por produtos e sistemas. Sendo o sector da construção responsável por grande parte desses impactes, é evidente a necessidade de aplicação de medidas que visem mitigar ou, no mínimo, reduzir até valores aceitáveis, essas agressões ao meio ambiente. Nesse âmbito, é natural que tenha surgido a ideia de aplicar uma metodologia tão precisa e rigorosa como a LCA ao sector da construção. No entanto, nos dias de hoje, as preocupações alargaram-se às vertentes social e económica que, juntamente com a vertente ambiental, formam o triângulo de equilíbrio do desenvolvimento sustentável. É precisamente essa avaliação tripartida que esta Dissertação pretende abordar, tentando aprofundar conhecimentos e fornecer alternativas, através da análise crítica, que possam contribuir para a melhoria contínua desta metodologia.

Drilling damage in composite material

The characteristics of carbon fibre reinforced laminates have widened their use from aerospace to domestic appliances, and new possibilities for their usage emerge almost daily. In many of the possible applications, the laminates need to be drilled for assembly purposes. It is known that a drilling process that reduces the drill thrust force can decrease the risk of delamination. In this work, damage assessment methods based on data extracted from radiographic images are compared and correlated with mechanical test results—bearing test and delamination onset test—and analytical models. The results demonstrate the importance of an adequate selection of drilling tools and machining parameters to extend the life cycle of these laminates as a consequence of enhanced reliability.

Incorporating sustainability into a chemical company’s modus operandi

The intent of this dissertation is to review relevant existing management systems and chemical industry initiatives to identify synergies, overlaps and gaps with Sustainability best practices, to map the barriers to the incorporation of Sustainability and formulate recommendations to facilitate execution of Sustainability practices within existing management systems. A chemical industry Sustainability survey was conducted through APEQ, the Portuguese association of chemical companies, which constitutes the first baseline on the topic for this national industry association. The commonly used international standards and the Responsible Care® (RC) initiative were cross-referenced against the United Nations Global Compact Assessment Tool. Guidance on how to incorporate Sustainability into a company‘s modus operandi was collapsed into Sustainability Playbooks. The survey revealed that 73% of the APEQ member companies that participated in the survey have a Sustainability Plan. Both large and small/medium APEQ member companies see the market not willing to pay extra for ‗greener‘ products as one of the main barriers. APEQ large enterprise see complexity of implementation and low return on investment as the other most significant barriers while small/medium enterprise respond that the difficulty to predict customer sustainability needs is the other most significant barrier. Amongst many other insights from this survey reported to APEQ, Life Cycle Assessment practices were found to have a low level of implementation and were also considered of low importance, thus identifying a very important opportunity in Sustainability practices to be addressed by APEQ. Two hundred and seventy three assessment points from United Nations Global Compact Assessment Tool plus five additional items were cross-referenced with international standard requirements. With the authorization of the intellectual property owners, the United Nations Global Compact Assessment Tool was modified to introduce actionable recommendations for each gap identified by management standard. This tool was automated to output specific recommendations for 63 possible combinations after simply selecting from a list of commonly used management standards and the RC initiative. Finally this modified tool was introduced into Playbooks for Incorporation of Sustainability at two levels: a ―Get Started Playbook‖ for beginners or small/medium size enterprise and an ―Advanced Playbook‖ as a second advancement stage or for large enterprise.

Sustentabilidade na reablitação urbana

A indústria da construção é um setor com grande impacto na economia, no Produto Interno Bruto (PIB) e ainda em postos de trabalho diretos e indiretos. No entanto, é um dos setores com maior impacte ambiental. Com a crise económica e financeira que o país atravessa, este setor foi um dos mais afetados, contribuindo para o aumento do desemprego visto tratar-se do setor com maior taxa de empregabilidade. Concomitantemente, ocorre saturação do mercado com a construção nova e desertificação dos centros urbanos com a degradação das habitações. Assim, como impulsionador da economia, surge a aposta na reabilitação do parque edificado que, com a legislação em vigor e com os incentivos dados pela tutela tem tudo para impulsionar o setor. Sabendo que a indústria da construção é um dos setores com maiores impactes ambientais, faz todo o sentido reabilitar-se de uma forma mais sustentável. Aplicando os princípios da sustentabilidade a todo o ciclo de vida do edifício, conseguimos reduzir os recursos na fase de construção (resíduos de construção) e na fase de exploração (consumo de energia e de água). Podemos ainda reduzir os custos de energia para climatização ao termos em conta a orientação do edifício e a envolvente, os recursos naturais e aplicando tecnologias solares passivas. Assim, ao aplicarmos os princípios da construção sustentável na reabilitação urbana podemos diminuir os impactes ambientais, a produção de CO2, as emissões de gases com efeito de estufa, os resíduos de construção e a área impermeabilizada.

A evolução de um modelo BIM de construção para gestão de empreendimentos

A implementação da evolução tecnológica no setor da construção tem se caracterizado pelo aparecimento de novas tecnologias que dinamizam os processos de troca de informação entre os vários intervenientes no ciclo de vida do empreendimento. O surgimento da tecnologia Building Information Modeling - BIM assente na modelação paramétrica e na interoperabilidade suportada em ficheiros de padrão aberto (IFC) pressupõem um novo paradigma na forma como são tratados os processos de troca de informação entre os vários intervenientes no ciclo de vida dos empreendimentos. Com base no BIM o Construction Operations Building Information Exchange – COBie, é outra tecnologia recente que recolhe informações não geométricas associadas ao modelo e em conjunto com a informação geométrica produzida pelo BIM fazem parte dos documentos de entrega para a fase Facility Management – FM. O objetivo da presente dissertação centrou-se no estudo da evolução de um modelo BIM de construção para a gestão de empreendimento. Foi desenvolvido o estudo de um modelo protótipo que incidiu na utilização de softwares para verificação e aplicação das tecnologias COBie e BIM e também foi sincronizado com a fase FM. Da aplicação dos requisitos COBie e modelação BIM foram extraídas informações geométricas e não geométricas preenchidas nas folhas de trabalho COBie. As principais conclusões do estudo realizado foram que as tecnologias COBie e BIM têm pouca implantação a nível nacional e a sua integração dinamiza os processos, reduzindo custos e aumentando a qualidade da informação fornecida.

PExIL: Programming Exercises Interoperability Language

Several standards appeared in recent years to formalize the metadata of learning objects, but they are still insufficient to fully describe a specialized domain. In particular, the programming exercise domain requires interdependent resources (e.g. test cases, solution programs, exercise description) usually processed by different services in the programming exercise life-cycle. Moreover, the manual creation of these resources is time-consuming and error-prone leading to what is an obstacle to the fast development of programming exercises of good quality. This paper focuses on the definition of an XML dialect called PExIL (Programming Exercises Interoperability Language). The aim of PExIL is to consolidate all the data required in the programming exercise life-cycle, from when it is created to when it is graded, covering also the resolution, the evaluation and the feedback. We introduce the XML Schema used to formalize the relevant data of the programming exercise life-cycle. The validation of this approach is made through the evaluation of the usefulness and expressiveness of the PExIL definition. In the former we present the tools that consume the PExIL definition to automatically generate the specialized resources. In the latter we use the PExIL definition to capture all the constraints of a set of programming exercises stored in a learning objects repository.

Using the Common Cartridge profile to enhance learning content interoperability

The concept of Learning Object (LO) is crucial for the standardization on eLearning. The latest LO standard from IMS Global Learning Consortium is the IMS Common Cartridge (IMS CC) that organizes and distributes digital learning content. By analyzing this new specification we considered two interoperability levels: content and communication. A common content format is the backbone of interoperability and is the basis for content exchange among eLearning systems. Communication is more than just exchanging content; it includes also accessing to specialized systems and services and reporting on content usage. This is particularly important when LOs are used for evaluation. In this paper we analyze the Common Cartridge profile based on the two interoperability levels we proposed. We detail its data model that comprises a set of derived schemata referenced on the CC schema and we explore the use of the IMS Learning Tools Interoperability (LTI) to allow remote tools and content to be integrated into a Learning Management System (LMS). In order to test the applicability of IMS CC for automatic evaluation we define a representation of programming exercises using this standard. This representation is intended to be the cornerstone of a network of eLearning systems where students can solve computer programming exercises and obtain feedback automatically. The CC learning object is automatically generated based on a XML dialect called PExIL that aims to consolidate all the data need to describe resources within the programming exercise life-cycle. Finally, we test the generated cartridge on the IMS CC online validator to verify its conformance with the IMS CC specification.

A case study on the improvement of eco-efficiency ratios: application to a composite processing industry

The World Business Council for Sustainable Development (WBCSD) defines Eco-Efficiency as follows: ‘Eco- Efficiency is achieved by the delivery of competitively priced-goods and services that satisfy human needs and bring quality of life, while progressively reducing ecological impacts and resource intensity throughout the life-cycle to a level at least in line with the earth’s estimated carrying capacity’. Eco-Efficiency is under this point of view a key concept for sustainable development, bringing together economic and ecological progress. Measuring the Eco-Efficiency of a company, factory or business, is a complex process that involves the measurement and control of several and relevant parameters or indicators, globally applied to all companies in general, or specific according to the nature and specificities of the business itself. In this study, an attempt was made in order to measure and evaluate the eco-efficiency of a pultruded composite processing company. For this purpose the recommendations of WBCSD [1] and the directives of ISO 14301 standard [2] were followed and applied. The analysis was restricted to the main business branch of the company: the production and sale of standard GFRP pultrusion profiles. The main general indicators of eco-efficiency, as well as the specific indicators, were defined and determined according to ISO 14031 recommendations. With basis on indicators’ figures, the value profile, the environmental profile, and the pertinent eco-efficiency’s ratios were established and analyzed. In order to evaluate potential improvements on company eco-performance, new indicators values and ecoefficiency ratios were estimated taking into account the implementation of new proceedings and procedures, both in upstream and downstream of the production process, namely: a) Adoption of new heating system for pultrusion die in the manufacturing process, more effective and with minor heat losses; b) Implementation of new software for stock management (raw materials and final products) that minimize production failures and delivery delays to final consumer; c) Recycling approach, with partial waste reuse of scrap material derived from manufacturing, cutting and assembly processes of GFRP profiles. In particular, the last approach seems to significantly improve the eco-efficient performance of the company. Currently, by-products and wastes generated in the manufacturing process of GFRP profiles are landfilled, with supplementary added costs to this company traduced by transport of scrap, landfill taxes and required test analysis to waste materials. However, mechanical recycling of GFRP waste materials, with reduction to powdered and fibrous particulates, constitutes a recycling process that can be easily attained on heavy-duty cutting mills. The posterior reuse of obtained recyclates, either into a close-looping process, as filler replacement of resin matrix of GFRP profiles, or as reinforcement of other composite materials produced by the company, will drive to both costs reduction in raw materials and landfill process, and minimization of waste landfill. These features lead to significant improvements on the sequent assessed eco-efficiency ratios of the present case study, yielding to a more sustainable product and manufacturing process of pultruded GFRP profiles.

Sustainability Evaluation of Biodiesel Produced from Microalgae Chlamydomonas sp Grown in Brewery Wastewater

This study performs a sustainability evaluation of biodiesel from microalga Chlamydomonas sp. grown in 20 % (v/v) of brewery’s wastewater, blended with pentose sugars (xylose, arabinose or ribose resulting from the hydrolysis of brewer’s spent grains (BSG). The life cycle steps considered for the study are: microalgae cultivation, biomass processing and lipids extraction at the brewery site, and its conversion to biodiesel at a dedicated external biofuel’s plant. Three sustainability indicators (LCEE, FER and GW) were considered and calculated using experimental data. Literature data was used, whenever necessary, to complement life cycle data, thus allowing a more accurate sustainability evaluation. A comparative analysis of the biodiesel life cycle steps was also conducted, with the main goal of identifying which steps need to be improved. Results show that biomass processing, especially cell harvesting, microalgae cultivation, and lipids extraction are the main process bottlenecks. It is also analysed the influence on the microalgae biodiesel sustainability of adding each pentose sugar to the cultivation media, concluding that it strongly influences the biomass and lipid productivity. In particular, the addition of xylose is preferable in terms of lipid productivity, but from a sustainability point of view, ribose is the best, though the difference from xylose is not significant. Nevertheless, culture without pentose addition presents the best sustainability results.

Marketing for future: Eddmi – Pass Platform

In a highly competitive market companies know that having quality products or provide good services is not enough to keep customers "faithful". Currently, quality of products/services, location and price are fundamental aspects customers expect to get on every purchase, so they look for ways to distinguish companies. This can happen either in a strictly materialistic way or by evaluation of intangible metrics such as having his opinion appreciated or being part of a selected group of "premium" customers. Therefore, companies must find ways to value and reward its customers in order to keep them "faithful" to their products or services. Loyalty systems are one means to achieve this goal, however, due to its nature and how they are implemented, often companies end up having low acceptance, without achieving intended objectives. In an era of technological revolution, where global average adoption of smartphones and tablets is 74% and 40% [Our Mobile Planet, 2014], the opportunity to reinvent loyalty systems reappears. Throughout this thesis a new tool, relying on the latest technologies and aiming to fulfill this market opportunity, will be presented. The main idea is to use ancient loyalty concepts, such as stamps or pointscards, and transforms them into digital cards, to be used in digital wallets, introducing an innovative technology component based on Apple's Passbook technology. The main goal is to create a platform for managing the card’s life cycle, allowing anyone to create, edit, distribute and analyze the data, and also create a new communication channel with customers, improving the customer-­‐supplier relationship and enhancing the mobile-­‐marketing.
