Reabilitação de um Edifício de Serviços no Porto para função de Hotel

Este relatório de estágio aborda o tema da reabilitação, referindo-se a uma intervenção da especialidade e também construção de raíz, de um Hotel situado na rua do Heroísmo no Porto. Portugal possui um edificado que tem vindo a degradar-se ao longo dos últimos anos, devido essencialmente à falta de operações periódicas de manutenção, conservação e reabilitação. Esta degradação resulta não só do mau estado de conservação generalizado dos edifícios, mas também da inexistência de infra-estruturas urbanísticas em devido funcionamento. Tal conjunto de situações, leva a um movimento migratório dos habitantes das cidades para as respetivas periferias. A cidade do Porto não é uma exceção, estando a necessitar de um forte esforço de reabilitação para inverter esta situação. Ao longo dos últimos anos têm vindo a ser criados diversos apoios financeiros, nacionais e europeus, com o objetivo de ajudar as operações de reabilitação. Mais recentemente foi possibilitada a criação de Sociedades de Reabilitação Urbana (SRU), cujo objetivo é o de promover e orientar todo o processo de reabilitação, de forma a regula-lo nos centros das cidades. No entanto a intervenção de reabilitação de um edifício é uma operação complexa, com diversas especificidades e com inúmeras condicionantes devido às pré-existências próprias de cada edifício.

Building a knowledge and learning society in Portugal: adult students in technological schools and higher education institutions

Lifelong learning (LLL) has received increasing attention in recent years. It implies that learning should take place at all stages of the “life cycle and it should be life-wide, that is embedded in all life contexts from the school to the work place, the home and the community” (Green, 2002, p.613). The ‘learning society’, is the vision of a society where there are recognized opportunities for learning for every person, wherever they are and however old they happen to be. Globalization and the rise of new information technologies are some of the driving forces that cause depreciation of specialised competences. This happens very quickly in terms of economic value; consequently, workers of all skills levels, during their working life, must have the opportunity to update “their technical skills and enhance general skills to keep pace with continuous technological change and new job requirements” (Fahr, 2005, p. 75). It is in this context that LLL tops the policy agenda of international bodies, national governments and non-governmental organizations, in the field of education and training, to justify the need for LLL opportunities for the population as they face contemporary employability challenges. It is in this context that the requirement and interest to analyse the behaviour patterns of adult learners has developed over the last few years

Paul Auster and the music of change: building new stories

In the work of Paul Auster (Newark, 1947 - ), we find two main themes: the sense of loss and existential drift and the loneliness of the individual fully committed to the work of writing, as if he had been confined to the book that commands his life. However, this second theme is clearly the dominant one because the character's space of solitude may include its own wandering, because this wandering is also often performed inside the four walls of a room, just like it is narrated inside the space of the page and the book. Both in his poetry, essays and fiction, Auster seems to face the work of writing as an actual physical effort of effective construction, as if the words that are aligned in the poem-text were stones to place in a row when building a wall or some other structure in stone.

Análise da obra "Mão Morta - Müller no Hotel Hessischer Hof (1998/2006)"

No âmbito da prova para título de especialista em Áudiovisuais e Produção dos Media, à qual me proponho, pretende-se fazer uma reflexão sobre o vídeo musical, desde a sua realização à pós-produção, dentro de um contexto nacional e em como a sua importância pode influenciar o ensino do audiovisual. Um vídeo musical é também uma curta metragem com características peculiares onde o papel da música ganha o primeiro plano. Por esta razão, pretende-se também estabelecer uma relação com a produção cinematográfica. O texto divide-se em cinco partes. Na primeira, contextualiza-se o vídeo musical numa tentativa de definição e enquadramento histórico internacional e nacional. Na segunda e terceiras partes, seguindo uma lógica de separação estrutural definida na obra de Rabiger (2004), dividiu-se as questões relacionadas com a estética das de identidade na autoria da criação de vídeos musicais. Esta separação fundamenta-se na associação da autoria de decisão autónoma, e da influência direta de terceiros no ato de criação. A quarta parte faz uma revisão das metodologias de trabalho para um vídeo musical com breves reflexões à sua relação com as da produção cinematográfica. Na quinta parte, faz-se uma reflexão mais detalhada do filme “Müller no Hotel Hessischer Hof”, a obra que se propõe para estudo e discussão, e que se entende apresentar como exemplo resultante de toda a experiência anterior do seu autor, e que se considera pertinente para abrir a discussão dos aspetos técnicos, das opções de realização e da pós-produção (dando especial importância à montagem). “Müller no Hotel Hessischer Hof” foi uma obra de importância vital para a afirmação do seu autor, uma vez que é a primeira que tem distribuição nacional em edição vídeo comercial. Para além disso, foi o primeiro trabalho de longa duração que realizou, um ano depois de ter recebido um dos prémios mais importantes na área do vídeo musical: o Prémios Blitz. Tratando-se de um filme feito na década de 90, ainda com equipamento de vídeo analógico, pode parecer desatualizado perante os avanços tecnológicos ocorridos nos últimos anos. No entanto deve ser visto como uma obra que resulta de um processo experimental e como tal obedeceu a uma lógica de construção que é herança de experiências adquiridas. Como em qualquer processo de aprendisagem, a experientação deve ser uma prática dominante. Este filme foi a oportunidade de pôr em prática processos e ideias que foram sendo testados em ambiente profissional. Porque se trata de um laboratório vivo, a produção de vídeos musicais permite e promove as ideias. Esse potencial deve ser considerado no universo pedagógico mantendo -o sempre numa relação estreita com o mundo profissional. Defendendo a ideia que a criatividade deve ser estimulada pela imaginação, apresenta-se numa obra que, graças às sua singularidade, foi produzida com recurso a uma grande necessidade laboratorial e que recorreu a soluções que resultaram tanto do exercício como da imaginação, uma alternativa ao modelo convencional. “Müller no Hotel Hessischer Hof” não pretende ser um exemplo perfeito mas pela suas condições de produção deve ser vista como uma obra de liberdade criativa, um bom exemplo para estudo e de entendimento para a relação entre a realização e a pós-produção.

Contrastive terminology: semitic, anglo-germanic and latin concept building through complex terms. (avoiding one-way method procedures in translation

This paper aims to present a contrastive approach between three different ways of building concepts after proving the similar syntactic possibilities that coexist in terms. However, from the semantic point of view we can see that each language family has a different distribution in meaning. But the most important point we try to show is that the differences found in the psychological process when communicating concepts should guide the translator and the terminologist in the target text production and the terminology planning process. Differences between languages in the information transmission process are due to the different roles the different types of knowledge play. We distinguish here the analytic-descriptive knowledge and the analogical knowledge among others. We also state that none of them is the best when determining the correctness of a term, but there has to be adequacy criteria in the selection process. This concept building or term building success is important when looking at the linguistic map of the information society.

Industrial ethernet: building blocks for a holistic approach

For industrial environments it is true that Ethernet technologies are there to stay. In fact, a number of characteristics are boosting the eagerness of extending Ethernet to also cover factory-floor applications. Fullduplex links, non-blocking and priority-based switching, bandwidth availability, just to mention a few, are characteristics upon which that eagerness is building up. But, will Ethernet technologies really manage to replace traditional field bus networks? Fieldbus fundamentalists often argue that the two things are not comparable. In fact, Ethernet technology, by itself, does not include features above the lower layers of the OSI communication model. Where are the higher layers and the application enablers that permit building real industrial applications? And, taking for free that they are available, what is the impact of those protocols, mechanisms and application models on the overall performance of Ethernet-based distributed factory-floor applications?

Building a microscope for the data center

Managing the physical and compute infrastructure of a large data center is an embodiment of a Cyber-Physical System (CPS). The physical parameters of the data center (such as power, temperature, pressure, humidity) are tightly coupled with computations, even more so in upcoming data centers, where the location of workloads can vary substantially due, for example, to workloads being moved in a cloud infrastructure hosted in the data center. In this paper, we describe a data collection and distribution architecture that enables gathering physical parameters of a large data center at a very high temporal and spatial resolutionof the sensor measurements. We think this is an important characteristic to enable more accurate heat-flow models of the data center andwith them, _and opportunities to optimize energy consumption. Havinga high resolution picture of the data center conditions, also enables minimizing local hotspots, perform more accurate predictive maintenance (pending failures in cooling and other infrastructure equipment can be more promptly detected) and more accurate billing. We detail this architecture and define the structure of the underlying messaging system that is used to collect and distribute the data. Finally, we show the results of a preliminary study of a typical data center radio environment.

Software transactional memory as a building block for parallel embedded realtime systems

The recent trends of chip architectures with higher number of heterogeneous cores, and non-uniform memory/non-coherent caches, brings renewed attention to the use of Software Transactional Memory (STM) as a fundamental building block for developing parallel applications. Nevertheless, although STM promises to ease concurrent and parallel software development, it relies on the possibility of aborting conflicting transactions to maintain data consistency, which impacts on the responsiveness and timing guarantees required by embedded real-time systems. In these systems, contention delays must be (efficiently) limited so that the response times of tasks executing transactions are upper-bounded and task sets can be feasibly scheduled. In this paper we assess the use of STM in the development of embedded real-time software, defending that the amount of contention can be reduced if read-only transactions access recent consistent data snapshots, progressing in a wait-free manner. We show how the required number of versions of a shared object can be calculated for a set of tasks. We also outline an algorithm to manage conflicts between update transactions that prevents starvation.

Building adaptable, QoS-aware dependable embedded systems

Most of today’s embedded systems are required to work in dynamic environments, where the characteristics of the computational load cannot always be predicted in advance. Furthermore, resource needs are usually data dependent and vary over time. Resource constrained devices may need to cooperate with neighbour nodes in order to fulfil those requirements and handle stringent non-functional constraints. This paper describes a framework that facilitates the distribution of resource intensive services across a community of nodes, forming temporary coalitions for a cooperative QoSaware execution. The increasing need to tailor provided service to each application’s specific needs determines the dynamic selection of peers to form such a coalition. The system is able to react to load variations, degrading its performance in a controlled fashion if needed. Isolation between different services is achieved by guaranteeing a minimal service quality to accepted services and by an efficient overload control that considers the challenges and opportunities of dynamic distributed embedded systems.

Impact of design options in zero energy building conception: the case of large buildings in Portugal

The new recast of Directive 2010/31/EU in order to implement the new concept NZEB in new buildings, is to be fully respected by all Member States, and is revealed as important measure to promote the reduction of energy consumption of buildings and encouraging the use of renewable energy. In this study, it was tested the applicability of the nearly zero energy building concept to a big size office building and its impact after a 50-years life cycle span.

Effects of hotel characteristics on room rates in Porto: a hedonic price approach

According to the hedonic price method, a price of a good is related with the characteristics or the services it provides. Within this framework, the aim of this study it is to examine the effect on room rates of different characteristics of hotels in and around the city of Porto, such as star category, size, room and service quality, hotel facilities and location. It was estimated a hedonic price function, using data for 51 hotels. The results enable to identify the attributes that are important to consumers and hoteliers and to which extent. This information can be used by hotel managers to define a price strategy and helpful in new investment decisions.

Ontology methodology building criteria for crowdsourcing innovation intermediaries

Crowdsourcing innovation intermediaries are organizations that mediate the communication and relationship between companies that aspire to solve some problem or to take advantage of any business opportunity with a crowd that is prone to give ideas based on their knowledge, experience and wisdom. A significant part of the activity of these intermediaries is carried out by using a web platform that takes advantage of web 2.0 tools to implement its capabilities. Thus, ontologies are presented as an appropriate strategy to represent the knowledge inherent to this activity and therefore the accomplishment of interoperability between machines and systems. In this paper we present an ontology roadmap for developing crowdsourcing innovation ontology of the intermediation process. We start making a literature review on ontology building, analyze and compare ontologies that propose the development from scratch with the ones that propose reusing other ontologies, and present the criteria for selecting the methodology. We also review enterprise and innovation ontologies known in literature. Finally, are taken some conclusions and presented the roadmap for building crowdsourcing innovation intermediary ontology.

HRM specificities’ on Portugal hotel units

This paper presents the main Human Resources Management (HRM) specificities’ on Portuguese hotel units. We try to understand the role of HRM on behavior of co-workers and quality service in hotel units and to know the future tendency of human capital profile on Portuguese hotel units and the role of HRM function on management of their staff. We, also, try to explore if Portuguese culture has influence on HRM specificities’ of hotel units. This phenomenon has a special relevance in the Portuguese context, because this country is known a growing process of tourism industry in recent years. Furthermore, little is known about HRM department’ contributions to their human capital management and development. This paper is one of the first to focus specifically on Portuguese hotel units and it also seeks to present findings that stem from the Human Resources Managers’ perspective. The paper is based on qualitative case studies. The data were collected through semi-structured interviews of 12 human resource managers from 12 hotel units located in Portugal. The results show that although there is not an effective HRM, current HRM practices are enough to encouraging pro-environmental behavior in their staff and they have a direct effect on customer satisfaction and competitiveness of sector. However, managers recognize there is need introduce some change on short-term to promote a better performance of staff with effect on customers satisfaction and competitiveness on sector in Portugal. According to these results, the paper discusses the major theoretical and practical implications.

Building Smarter Cities through Social Entrepreneurship

The objective of the present study is to examine the extent to which social ventures are able to increase the smartness of the cities. To achieve this goal, we adopt a qualitative approach, based on the case study method to obtain valuable insights about different characteristics and strategies of Cais (a non-profit association dedicated to help disadvantaged people in urban areas). By focusing on the analysis of the Cais activities, we assess whether its social intervention match the dimensions proposed by Giffinger et al. (2007) to rank smart cities’ performance, namely if it has smart: (i) economy; (ii) people; (iii) governance; (iv) mobility; (v) environment; and (vi) living. The research shows that the action pursued comprises elements from all the above mentioned dimensions. Further, the analysis reveals that Cais reinforces the smartness of the city where it acts (attributes such as living, economy, people, and environment).
