Geography of the Information Society

All every day activities take place in space. And it is upon this that all information and knowledge revolve. The latter are the key elements in the organisation of territories. Their creation, use and distribution should therefore occur in a balanced way throughout the whole territory in order to allow all individuals to participate in an egalitarian society, in which the flow of knowledge can take precedence over the flow of interests. The information society depends, to a large extent, on the technological capacity to disseminate information and, consequently, the knowledge throughout territory, thereby creating conditions which allow a more balanced development, from the both the social and economic points of view thus avoiding the existence of info-exclusion territories. Internet should therefore be considered more than a mere technology, given that its importance goes well beyond the frontiers of culture and society. It is already a part of daily life and of the new forms of thinking and transmitting information, thus making it a basic necessity essential, for a full socio-economic development. Its role as a platform of creation and distribution of content is regarded as an indispensable element for education in today’s society, since it makes information a much more easily acquired benefit.”…in the same way that the new technologies of generation and distribution of energy allowed factories and large companies to establish themselves as the organisational bases of industrial society, so the internet today constitutes the technological base of the organisational form that characterises the Information Era: the network” (CASTELLS, 2004:15). The changes taking place today in regional and urban structures are increasingly more evident due to a combination of factors such as faster means of transport, more efficient telecommunications and other cheaper and more advanced technologies of information and knowledge. Although their impact on society is obvious, society itself also has a strong influence on the evolution of these technologies. And although physical distance has lost much of the responsibility it had towards explaining particular phenomena of the economy and of society, other aspects such as telecommunications, new forms of mobility, the networks of innovation, the internet, cyberspace, etc., have become more important, and are the subject of study and profound analysis. The science of geographical information, allows, in a much more rigorous way, the analysis of problems thus integrating in a much more balanced way, the concepts of place, of space and of time. Among the traditional disciplines that have already found their place in this process of research and analysis, we can give special attention to a geography of new spaces, which, while not being a geography of ‘innovation’, nor of the ‘Internet’, nor even ‘virtual’, which can be defined as one of the ‘Information Society’, encompassing not only the technological aspects but also including a socio-economic approach. According to the last European statistical data, Portugal shows a deficit in terms of information and knowledge dissemination among its European partners. Some of the causes are very well identified - low levels of scholarship, weak investments on innovation and R&D (both private and public sector) - but others seem to be hidden behind socio-economical and technological factors. So, the justification of Portugal as the case study appeared naturally, on a difficult quest to find the major causes to territorial asymmetries. The substantial amount of data needed for this work was very difficult to obtain and for the islands of Madeira and Azores was insufficient, so only Continental Portugal was considered for this study. In an effort to understand the various aspects of the Geography of the Information Society and bearing in mind the increasing generalised use of information technologies together with the range of technologies available for the dissemination of information, it is important to: (i) Reflect on the geography of the new socio-technological spaces. (ii) Evaluate the potential for the dissemination of information and knowledge through the selection of variables that allow us to determine the dynamic of a given territory or region; (iii) Define a Geography of the Information Society in Continental Portugal.

Geografia Virtual – A Representação do(s) Lugar(es) Físico(s) no Espaço da Internet

A Geografia tem a ver com o lugar, com a localização, com a sociedade, com o ambiente, com o espaço e com a região. Uma vez que no ciberespaço algumas destas variáveis são difíceis de definir, o campo de pesquisa da geografia virtual terá que ser aprofundado,. Este novo domínio da análise geográfica apresenta-se como uma forma de percepcionar a representação do(s) espaço(s) físico(s) no espaço virtual da Internet. Este artigo pretende mostrar um exemplo de um ‘interface’ de cartografia digital, disponível on-line, que pelas suas características inovadoras representa ‘o estado da arte’ na análise dos espaços reais ou geográficos, no espaço virtual da Internet. A sua escolha prende-se com o facto desta ferramenta utilizar conceitos e fundamentos da Geografia, aos quais foram aplicadas as modernas tecnologias de programação para ambientes da www, como as linguagens VRML, XML, Java e Flash.

Distributed Generation and Demand Response Dispatch for a Virtual Power Player Energy and Reserve Provision

Recent changes in the operation and planning of power systems have been motivated by the introduction of Distributed Generation (DG) and Demand Response (DR) in the competitive electricity markets' environment, with deep concerns at the efficiency level. In this context, grid operators, market operators, utilities and consumers must adopt strategies and methods to take full advantage of demand response and distributed generation. This requires that all the involved players consider all the market opportunities, as the case of energy and reserve components of electricity markets. The present paper proposes a methodology which considers the joint dispatch of demand response and distributed generation in the context of a distribution network operated by a virtual power player. The resources' participation can be performed in both energy and reserve contexts. This methodology contemplates the probability of actually using the reserve and the distribution network constraints. Its application is illustrated in this paper using a 32-bus distribution network with 66 DG units and 218 consumers classified into 6 types of consumers.

Transient Spaces: unsettling boundaries and norms at the cultural event Noc Noc, Guimarães, Portugal

Cities are increasingly expected to be creative, inventive and to exhibit intense expressivity. In the past decades many cities have experienced growing pressure to produce and stage cultural events of different sorts and to develop new strategies that optimize competitive advantages, in order to promote themselves and to boost and sell their image. Often these actions have relied on heavy public investment and major private corporation sponsoring, but it is not always clear or measured how successful and reproductive these investments have been. In the context of strained public finances and profound economic crisis of European peripheral countries, events that emerge from local communities and have low budgets, which manage to create significant fluxes of visitors and visibility, assume an increased interest. In order to reflect and sketch possible answers, we look to an emerging body of literature concerning creative cities, and we focus on the organisation of a particular cultural event and its impact and assimilation into a medium size Portuguese city. This paper looks at the two editions (2011 and 2012) of one of such events – Noc Noc – organized by a local association in the city of Guimarães, Portugal. Inspired by similar events, Noc Noc is based on creating transient spaces of culture which are explored by artists and audiences, by transforming numerous homes into ephemeral convivial and playful social ‘public’ environments. The event is based on a number of cultural venues/homes scattered around the old and newer city, which allows for an informal urban exploration and an autonomous rambling and getting lost along streets. This strategy not only disrupts the cleavages between public and private space permitting for various transgressions, but it also disorders normative urban experiences and unsettles the dominant role of the city council as the culture patron of the large majority of events. Guimarães, an UNESCO World Heritage City was the European Capital of Culture in 2012, with a public investment of roughly 73 million euro. By interviewing a sample of people who have hosted these transitory art performances and exhibitions, sometimes doubling as artists, the events’ organizers and by experience both editions of the event, this paper illustrates how urban citizens’ engagement and motivations in a low budget cultural event can strengthen community ties. Furthermore, it also questions the advantages of large scale high budget events, and how this event may be seen as unconscious counter movement against a commodification of cultural events and everyday urban experience at large, engaging with the concepts of staging and authenticity.

Realidade Imersiva Aplicada a Espaços Culturais

Informação é o conceito genérico de tudo que possa representar, conhecimento ou comunicação. Trata-se de conhecimento registado de forma impressa ou digital, oral ou audiovisual, mas ainda pode ser registada em suporte físico. Desde o início da civilização que o Ser Humano tenta criar novas formas de transmitir informação, antes da invenção da forma escrita era utilizado o método do desenho para descrever a realidade, este método ao longo do tempo foi evoluindo, ganhando mais qualidade, pormenor e suportes mais evoluídos. Mas sempre com a mesma intenção, a de conseguir transmitir de forma mais direta e percetível informação a qualquer individuo. Dado isto, o Ser Humano sempre produziu arte e a foi preservando para mostrar aos vindouros. Neste processo, os museus em conjunto com espaços culturais e artísticos, foram assumindo um papel de relevo na sociedade. Mas inicialmente o objetivo principal dos museus era o de preservar e expor artefactos históricos e culturais. A grande evolução tecnológica dos últimos anos veio dotar o Ser Humano com formas de aceder à informação tão simples e diversificadas, que no passado eram completamente impensáveis e certamente que no futuro irão ser descobertas ainda mais formas de registar e propagar a informação. Assim o presente trabalho descreve a investigação realizada, através de uma recolha de bibliografia, levantamento do estado-da-arte, que pretende descobrir se a construção de visitas virtuais imersivas é uma boa forma para mostrar um espaço cultural ao público, que está cada vez mais exigente e disperso geograficamente. Além do levantamento são estudados alguns exemplos de visitas virtuais existentes, de modo a detetar boas praticas e formas mais usuais para a criação de uma visita. Finalmente foi descrito todo o processo desde a recolha de informação até à própria implementação, construção de um protótipo para apresentar ao utilizador o espaço de uma fundação, a do escultor José Rodrigues. Este protótipo tem por objetivo mostrar ao utilizador a fundação o mais aproximado do real possível.

Geocaching como ferramenta de Marketing Digital

O Geocaching é um jogo, criado pela Groundspeak, que consiste em esconder e encontrar objetos geolocalizados conhecidos como geocaches. A busca das geocaches é na realidade uma aventura que promove a vivência de novas experiências, o convívio entre utilizadores, a descoberta de novos espaços na natureza, a realização de jogos em tempo e cenário real, entre outros. Existem geocaches espalhadas por todo o mundo e milhares de utilizadores estão já registados no jogo. Além de passatempo, o Geocaching consegue ser uma ferramenta de marketing digital, quer para a própria Groundspeak, mas também para diferentes empresas/instituições por todo o mundo normalmente associadas à localização das geocaches. A Groundspeak é, naturalmente, a mais beneficiada uma vez que, praticamente sem investir em publicidade, conseguiu que o jogo tenha cada vez mais adeptos. A sua divulgação é essencialmente feita pelos próprios utilizadores, quer através da comunicação direta com um não utilizador, quer através de redes sociais, de eventos organizados, mas também através de outras empresas que desenvolveram aplicações com funcionalidades extra que permitem ao utilizador uma melhor experiência. O objetivo desta dissertação foi o de demonstrar como é que o Geocaching pode ser usado como uma ferramenta de Marketing Digital. Inicialmente, foi analisada a questão do Marketing Digital e das suas ferramentas, focando o Geocaching e a sua dimensão no mundo, explicando os diferentes tipos de caches e de que forma as mesmas podem ser utilizadas como ferramentas de marketing. Como elemento de validação, foi concebida, desenvolvida e validada uma wherigo (um tipo de geocache), que consiste num jogo virtual onde o progresso do jogador depende das tarefas realizadas e da sua movimentação geolocalizada. A wherigo criada no âmbito do projeto é um meio de marketing digital, de divulgação do Castelo de Santa Maria da Feira, realizada de uma forma interativa e divertida, através de questionários, desafios e fantasia. O jogo incita a percorrer os jardins que rodeiam o Castelo bem como o interior do mesmo e permite ainda o acesso dos jogadores ao Castelo com desconto de geocacher na aquisição do ingresso. Os objetivos propostos inicialmente foram completamente cumpridos, sendo que o jogo já se encontra disponível para ser jogado por geocachers e foi por eles avaliado muito positivamente.

Virtual Power Player Using Demand Response to Deal with Unexpected Low Wind Power Generation

Demand response is assumed as an essential resource to fully achieve the smart grids operating benefits, namely in the context of competitive markets and of the increasing use of renewable-based energy sources. Some advantages of Demand Response (DR) programs and of smart grids can only be achieved through the implementation of Real Time Pricing (RTP). The integration of the expected increasing amounts of distributed energy resources, as well as new players, requires new approaches for the changing operation of power systems. The methodology proposed in this paper aims the minimization of the operation costs in a distribution network operated by a virtual power player that manages the available energy resources focusing on hour ahead re-scheduling. When facing lower wind power generation than expected from day ahead forecast, demand response is used in order to minimize the impacts of such wind availability change. In this way, consumers actively participate in regulation up and spinning reserve ancillary services through demand response programs. Real time pricing is also applied. The proposed model is especially useful when actual and day ahead wind forecast differ significantly. Its application is illustrated in this paper implementing the characteristics of a real resources conditions scenario in a 33 bus distribution network with 32 consumers and 66 distributed generators.

Short-term Wind Forecasting to Support Virtual Power Player Operation

This paper proposes a wind speed forecasting model that contributes to the development and implementation of adequate methodologies for Energy Resource Man-agement in a distribution power network, with intensive use of wind based power generation. The proposed fore-casting methodology aims to support the operation in the scope of the intraday resources scheduling model, name-ly with a time horizon of 10 minutes. A case study using a real database from the meteoro-logical station installed in the GECAD renewable energy lab was used. A new wind speed forecasting model has been implemented and it estimated accuracy was evalu-ated and compared with a previous developed forecast-ing model. Using as input attributes the information of the wind speed concerning the previous 3 hours enables to obtain results with high accuracy for the wind short-term forecasting.

Maximizing the Social Welfare of Virtual Power Players Operation in Case of Excessive Wind Power

The integration of growing amounts of distributed generation in power systems, namely at distribution networks level, has been fostered by energy policies in several countries around the world, including in Europe. This intensive integration of distributed, non-dispatchable, and natural sources based generation (including wind power) has caused several changes in the operation and planning of power systems and of electricity markets. Sometimes the available non-dispatchable generation is higher than the demand. This generation must be used; otherwise it is wasted if not stored or used to supply additional demand. New policies and market rules, as well as new players, are needed in order to competitively integrate all the resources. The methodology proposed in this paper aims at the maximization of the social welfare in a distribution network operated by a virtual power player that aggregates and manages the available energy resources. When facing a situation of excessive non-dispatchable generation, including wind power, real time pricing is applied in order to induce the increase of consumption so that wind curtailment is minimized. This method is especially useful when actual and day-ahead resources forecast differ significantly. The distribution network characteristics and concerns are addressed by including the network constraints in the optimization model. The proposed methodology has been implemented in GAMS optimization tool and its application is illustrated in this paper using a real 937-bus distribution network with 20.310 consumers and 548 distributed generators, some of them non-dispatchable and with must take contracts. The implemented scenario corresponds to a real day in Portuguese power system.
