Information and wildlife valuation: Experiments and policy

The authors use experimental surveys to investigate the association between individuals' knowledge of particular wildlife species and their stated willingness to allocate funds to conserve each. The nature of variations in these allocations between species (e.g., their dispersion) as participants' knowledge increases is examined. Factors influencing these changes are suggested. Willingness-to-pay allocations are found not to measure the economic value of species, but are shown to be policy relevant. The results indicate that poorly known species, e.g., in remote areas, may obtain relatively less conservation support than they deserve.

A Study of the Corporative Portals as a Tool of Explicit Knowledge Externalization in Universities

The corporative portals, enabled by Information Technology and Communication tools, provide the integration of heterogeneous data proceeding from internal information systems, which are available for access and sharing of the interested community. They can be considered an important instrument of explicit knowledge evaluation in the. organization, once they allow faster and,safer, information exchanges, enabling a healthful collaborative environment. In the specific case of major Brazilian universities, the corporate portals assume a basic aspect; therefore they offer an enormous variety and amount of information and knowledge, due to the multiplicity of their activities This. study aims to point out important aspects of the explicit knowledge expressed by the searched universities; by the analysis, of the content offered in their corporative portals` This is an exploratory study made through, direct observation of the existing contents in the corporative portals of two public universities as. Well as three private ones. A. comparative analysis of the existing contents in these portals was carried through;. it can be useful to evaluate its use as factor of optimization of the generated explicit knowledge in the university. As results, the existence of important differences, could be verified in the composition and in the content of the corporative portals of the public universities compared to the private institutions. The main differences are about the kind of services and the destination-of the,information that have as focus different public-target. It-could also be concluded that the searched private universities, focus, on the processes related to the attendance of the students, the support for the courses as well as the spreading of information to the public interested in joining the institution; whereas the anal public universities prioritize more specific information, directed to,the dissemination-of the research, developed internally or with institutional objectives.

Analyses of Individual and Organizational Competences Associated with Knowledge Management Practice

The research analyzed critical aspects of the knowledge management process based on the analyses of knowledge, abilities and attitudes required to individual knowledge workers and to organizations responsible for the management process. In the present work a characterization of the knowledge management process was developed and information and knowledge wokers defined. Competence concept was discussed and specialists gave opinions about critical competences to knowledge management process. The opinions were organized and analyzed by the Delphi method. The results aggregate to the management context by discussing an extremely important resource to organizations - knowledge - and because they support its management process. The research identified wide critical aspects that are compatible with current organizational challenges, directing the process management to important themes as: the worker able to create, the organization able to convert individual knowledge into organizational knowledge, knowledge sharing while still tacit, the maximization organizational knowledge use, information and knowledge generation and preservation, among others important topics to be observed by knowledge workers and by administrators responsible for the knowledge management process.

The therapeutic potential of dopamine modulators on the cardiovascular and renal systems

In the periphery, physiological dopamine increases renal blood flow, decreases renal resistance and acts on the kidney tubule to enhance natriuresis and diuresis. The loss of dopamine function may be involoved in the deterioration in kidney function associated with ageing and may have a role in the pathogenesis of hypertension and diabetes. Intravenous dopamine is used as a positive inotrope in the treatment of acute heart failure and cardiogenic shock and as a diuretic in renal failure. The clinical uses of dopamine are limited, as it must be given intravenously, and also has widespread effects. The levels of peripheral dopamine can be increased by the administration of L-dopa to increase synthesis, prodrugs to release dopamine (docarpamine, glu-dopa) or by inhibiting the breakdown of dopamine (nitecapone). Preliminary clinical trials suggest that docarpamine may be useful in patients with low cardiac output syndrome after cardiac surgery and in refractory cirrhotic ascites. Ibopamine is an agonist at dopamine D1 and D2 receptors, which may retard the progression of chronic renal failure. Gludopa is selective for the kidney thus avoiding widespread side effects. The early clinical studies with ibopamine as a diuretic in heart failure were favourable but the subsequent large mortality study showed that ibopamine increased mortality. Fenoldopam is a selective dopamine D1 receptor agonist. Intravenous fenoldopam may be useful in the treatment of hypertension associated with coronary artery bypass surgery or in hypertensive emergencies. Although our understanding of physiological and pathological roles of peripheral dopamine has been increasing rapidly in recent times, we still need more information to allow the design of clinically useful drugs that modify these roles. One priority is an orally-active selective dopamine D1 receptor agonist.

Tourism mobile and recommendation systems - a state of the art

Recommendation systems have been growing in number for the last fifteen years. To evolve and adapt to the demands of the actual society, many paradigms emerged giving birth to even more paradigms and hybrid approaches. Mobile devices have also been under an incredible growth rate in every business area, and there are already lots of mobile based systems to assist tourists. This explosive growth gave birth to different mobile applications, each having their own advantages and disadvantages. Since recommendation and mobile systems might as well be integrated, this work intends to present the current state of the art in tourism mobile and recommendation systems, as well as to state their advantages and disadvantages.

The invisible factors that can make the difference. Language management and knowledge transfer in multinational sites

The knowledge-based society we live in has stressed the importance of human capital and brought talent to the top of most wanted skills, especially to companies who want to succeed in turbulent environments worldwide. In fact, streams, sequences of decisions and resource commitments characterize the day-to-day of multinational companies (MNCs). Such decision-making activities encompass major strategic moves like internationalization and new market entries or diversification and acquisitions. In most companies, these strategic decisions are extensively discussed and debated and are generally framed, formulated, and articulated in specialized language often developed by the best minds in the company. Yet the language used in such deliberations, in detailing and enacting the implementation strategy is usually taken for granted and receives little if any explicit attention (Brannen & Doz, 2012) an can still be a “forgotten factor” (Marschan et al. 1997). Literature on language management and international business refers to lack of awareness of business managers of the impact that language can have not only in communication effectiveness but especially in knowledge transfer and knowledge management in business environments. In the context of MNCs, management is, for many different reasons, more complex and demanding than that of a national company, mainly because of diversity factors inherent to internationalization, namely geographical and cultural spaces, i.e, varied mindsets. Moreover, the way of functioning, and managing language, of the MNC depends on its vision, its values and its internationalization model, i.e on in the way the MNE adapts to and controls the new markets, which can vary essentially from a more ethnocentric to a more pluricentric focus. Regardless of the internationalization model followed by the MNC, communication between different business units is essential to achieve unity in diversity and business sustainability. For the business flow and prosperity, inter-subsidiary, intra-company and company-client (customers, suppliers, governments, municipalities, etc..) communication must work in various directions and levels of the organization. If not well managed, this diversity can be a barrier to global coordination and create turbulent environments, even if a good technological support is available (Feely et al., 2002: 4). According to Marchan-Piekkari (1999) the tongue can be both (i) a barrier, (ii) a facilitator and (iii) a source of power. Moreover, the lack of preparation for the barriers of linguistic diversity can lead to various costs, including negotiations’ failure and failure on internationalization.. On the other hand, communication and language fluency is not just a message transfer procedure, but above all a knowledge transfer process, which requires extra-linguistic skills (persuasion, assertiveness …) in order to promote credibility of both parties. For this reason, MNCs need a common code to communicate and trade information inside and outside the company, which will require one or more strategies, in order to overcome possible barriers and organization distortions.

Shannon information and power law analysis of the chromosome code

This paper studies the information content of the chromosomes of twenty-three species. Several statistics considering different number of bases for alphabet character encoding are derived. Based on the resulting histograms, word delimiters and character relative frequencies are identified. The knowledge of this data allows moving along each chromosome while evaluating the flow of characters and words. The resulting flux of information is captured by means of Shannon entropy. The results are explored in the perspective of power law relationships allowing a quantitative evaluation of the DNA of the species.

TV Recommendation and Personalization Systems: Integrating Broadcast and Video On-demand Services

he expansion of Digital Television and the convergence between conventional broadcasting and television over IP contributed to the gradual increase of the number of available channels and on demand video content. Moreover, the dissemination of the use of mobile devices like laptops, smartphones and tablets on everyday activities resulted in a shift of the traditional television viewing paradigm from the couch to everywhere, anytime from any device. Although this new scenario enables a great improvement in viewing experiences, it also brings new challenges given the overload of information that the viewer faces. Recommendation systems stand out as a possible solution to help a watcher on the selection of the content that best fits his/her preferences. This paper describes a web based system that helps the user navigating on broadcasted and online television content by implementing recommendations based on collaborative and content based filtering. The algorithms developed estimate the similarity between items and users and predict the rating that a user would assign to a particular item (television program, movie, etc.). To enable interoperability between different systems, programs characteristics (title, genre, actors, etc.) are stored according to the TV-Anytime standard. The set of recommendations produced are presented through a Web Application that allows the user to interact with the system based on the obtained recommendations.

Georeferencing Road Accidents with Google Earth: Transforming Information into Knowledge for Decision Support

Over the last fifty years mobility practices have changed dramatically, improving the way travel takes place, the time it takes but also on matters like road safety and prevention. High mortality caused by high accident levels has reached untenable levels. But the research into road mortality stayed limited to comparative statistical exercises which go no further than defining accident types. In terms of sharing information and mapping accidents, little progress has been mad, aside from the normal publication of figures, either through simplistic tables or web pages. With considerable technological advances on geographical information technologies, research and development stayed rather static with only a few good examples on dynamic mapping. The use of Global Positioning System (GPS) devices as normal equipments on automobile industry resulted in a more dynamic mobility patterns but also with higher degrees of uncertainty on road traffic. This paper describes a road accident georeferencing project for the Lisbon District involving fatalities and serious injuries during 2007. In the initial phase, individual information summaries were compiled giving information on accidents and its majour characteristics, collected by the security forces: the Public Safety Police Force (Polícia de Segurança Pública - PSP) and the National Guard (Guarda Nacional Republicana - GNR). The Google Earth platform was used to georeference the information in order to inform the public and the authorities of the accident locations, the nature of the location, and the causes and consequences of the accidents. This paper also gives future insights about augmented reality technologies, considered crucial to advances to road safety and prevention studies. At the end, this exercise could be considered a success because of numerous consequences, as for stakeholders who decide what to do but also for the public awareness to the problem of road mortality.

Text based on the paper presented at the Conference "Autonomous systems: inter-relations of technical and societal issues" held at Monte de Caparica (Portugal), Universidade Nova de Lisboa, November, 5th and 6th 2009 and organized by IET-Research Centre on Enterprise and Work Innovation

Knowledge Society and Geography: A Theoretical Approach

The transition process between information and knowledge is faster and so the inputs that influence social and political practises. The dissemination of information is now determinant in terms of territorial competitiveness and both public and private sector take large benefits when the data-information- knowledge value chain repeats itself trough space and time. Mankind depends nowadays on the creation and diffusion of good and reliable information. Speed is also important and the greater the speed, the faster the opportunities for global markets. Information must be an input for knowledge and obviously for decision. So, the power of information is unquestionable. This paper focuses on concepts like information, knowledge and other, more geographical and tries to explain how territories change from real to virtual. Knowledge society appears on an evolutional context in which information dissemination is wider and technological potential overwrites traditional notions of Geography. To understand the mutations over the territories, the causes and the consequences emerges the Geography of the Knowledge Society, a new discipline inside Geography with a special concern about modern society and socio-economical developing models.

Are societal changes new? Questions or trends and future perceptions on knowledge-based economy

With the emergence of a global division of labour, the internationalisation of markets and cultures, the growing power of supranational organisations and the spread of new information technologies to every field of life, it starts to appear a different kind of society, different from the industrial society, and called by many as ‘the knowledge-based economy’, emphasizing the importance of information and knowledge in many areas of work and organisation of societies. Despite the common trends of evolution, these transformations do not necessarily produce a convergence of national and regional social and economic structures, but a diversity of realities emerging from the relations between economic and political context on one hand and the companies and their strategies on the other. In this sense, which future can we expect to the knowledge economy? How can we measure it and why is it important? This paper will present some results from the European project WORKS – Work organisation and restructuring in the knowledge society (6th Framework Programme), focusing the future visions and possible future trends in different countries, sectors and industries, given empirical evidences of the case studies applied in several European countries, underling the importance of foresight exercises to design policies, prevent uncontrolled risks and anticipate alternatives, leading to different ‘knowledge economies’ and not to the ‘knowled

A eficiência energética nas redes de telecomunicações e tecnologias de informação e comunicação

A presente tese pretende fazer uma abordagem ao crescimento dos consumos de energia elétrica, que se tem verificado, nos últimos anos, no setor das telecomunicações e das tecnologias de informação; devido ao constante crescimento das redes, dos equipamentos a ela ligados e do tráfego que nelas transita. Num contexto de globalização da economia, no qual, as redes de telecomunicações e de energia elétrica são dois dos maiores contribuintes, a presente tese procura encontrar enquadramentos e soluções para um dos maiores desafios que a humanidade enfrenta atualmente, e que em parte, é consequente dessa globalização: encontrar novas fontes e formas de utilização da energia, -particularmente da energia elétrica - para que a humanidade continue a usufruir, de uma forma sustentável, dos benefícios que a mesma proporciona. Na primeira parte, procura-se fazer uma abordagem que utiliza fontes de informação e conhecimento, do mercado global, nomeadamente, entidades reguladoras e normalizadoras, operadores, fornecedores de tecnologias e consumidores, que abrangessem os três maiores mercados mundiais – União Europeia, Estados Unidos da América e Ásia-Pacífico. Considerou-se fundamental fazê-lo, por se tratar de uma dissertação no âmbito de um Mestrado com o selo de garantia EUR-ACE. Ao longo da dissertação analisou-se a temática da eficiência energética nas redes de telecomunicações e das tecnologias de informação e comunicação, um tema cada vez mais pertinente, já que o número de pessoas com ligações à Internet, já supera os 3 mil milhões, e as redes passaram a ser o meio por onde são transmitidos, a cada segundo, terabytes de sinais de voz, dados e vídeo. Procurou-se encontrar as linhas de orientação que estão a ser traçadas, para otimizar os consumos energéticos, de um complexo sistema convergente de redes e serviços, formado por entidades reguladoras e normalizadoras, operadores, fornecedores de tecnologias e consumidores, onde nem sempre as fronteiras estão perfeitamente definidas. Perante a constatação da realidade exposta, analisou-se as políticas energéticas desenvolvidas nos últimos anos, pelos vários players do mercado das telecomunicações, das tecnologias de informação e dos sistemas elétricos de energia bem como algumas métricas e objetivos comumente aceites. viii São analisados os contributos das partes interessadas, para o desenvolvimento de políticas energéticas eficazes, por forma a permitirem uma implementação, que considere o funcionamento dos equipamentos como um todo, e não de uma forma isolada como tradicionalmente o assunto era abordado. As especificidades na forma como funcionam as redes de telecomunicações e respetivos equipamentos, são expostas sobre várias óticas, comprovando-se que a temática da eficiência energética é uma das áreas mais difíceis lidar, de todas as consideradas nas políticas energéticas. Demonstrou-se que muitos dos equipamentos não estão otimizados em termos de gestão de energia, procurou-se evidenciar as consequências dessa realidade, uma vez que os equipamentos referidos, têm a necessidade de estar permanentemente a ser alimentados pela rede de energia elétrica, para garantir as funções para que foram projetados. Da pesquisa efetuada e descrita ao longo da dissertação, constatamos o empenho de toda a comunidade científica, operadores e agências de energia e de telecomunicações, em resolver o problema, já que há a consciencialização de que o ritmo de crescimento da rede e equipamentos terminais, é superior ao registado na melhoria da eficiência energética dos vários componentes e equipamentos terminais. Na segunda parte do relatório da tese, procurou-se testar a aplicabilidade das normas e recomendações dos organismos que tutelam a atividade a nível global - algumas publicadas nos últimos 2 anos - a um caso prático. Um edifício hospitalar de média dimensão. Foi elaborada uma aplicação informática, que suportada numa metodologia padronizada, seja capaz de fazer a avaliação da eficiência energética dos equipamentos serviços de telecomunicações de informação e comunicação em funcionamento do hospital. Por dificuldades de disponibilidade dos responsáveis do edifício, os resultados ficaram aquém do esperado. Conseguiu-se desenhar a aplicação, inventariar-se apenas parte dos equipamentos. Demonstrou-se que, a forma como alguns equipamentos estão a ser utilizados, não cumprem regras de utilização racional e eficiente. Procurou-se sensibilizar alguns dos responsáveis, para a necessidade de alterar comportamentos e prosseguir o processo de inventariação, por forma, a que o trabalho iniciado atinja os objetivos propostos.

Exergames - Jogos Sérios para Promover o Exercício Físico

As novas tecnologias, em particular os meios de entretimento digital, oferecem diferentes soluções de interação para que as pessoas se possam divertir. O elevado (e crescente) número de jogos digitais disponíveis no mercado permitiu o aparecimento de um novo tipo de jogos digitais, os jogos sérios, com uma finalidade menos lúdica. O intuito desses jogos é usar as caraterísticas associadas aos jogos normais, mas direcioná-los para uma finalidade séria. Assim, além de divertir o utilizador estes jogos também possibilitam a transmissão de informação e conhecimento que de outra forma não teria o mesmo impacto, por falta de interesse e menor motivação dos utilizadores. Exergames são jogos digitais utilizados para o desenvolvimento pessoal como o propósito de melhorar o bem-estar das pessoas quer a nível físico quer a nível mental. Esses jogos requerem que partes do corpo estejam em constante movimento, sendo que alguns utilizam dispositivos de rastreio de movimentos do corpo como forma de interação com os sistemas. Os exergames são o foco desta tese, com uma análise das suas potencialidades e das diferentes áreas possíveis para a sua aplicabilidade. São analisados diferentes tipos de exergames consoante o dispositivo que irá permitir a utilização do jogo. Também são estudados algumas ferramentas externas que possibilitam a interação de aplicações móveis com equipamentos de exercício físico específicos. A componente prática da tese contempla a criação de um exergame para dispositivos móveis com o intuito de incentivar as pessoas para a prática de corridas de forma regular, para que possam ter um estilo de vida ativo e que contribui de forma direta para o bem-estar deles. Os testes realizados junto a um conjunto de pessoas conduziram a resultados positivos quer do jogo desenvolvido quer da utilidade deste tipo de jogos no desenvolvimento físico, o que permite afirmar que os exergames devido ao seu carácter sério, mas nunca deixando de parte a diversão e a interatividade, são motivadores extras para as pessoas praticarem exercício físico.
