‘Thy love afar is spite at home' Emerson, Thoreau and Carey: an alternative perspective of communication in US

The conquest of the West by the stagecoaches and then by railway, Ford and the automobile civilization, the Moon landing by Apollo 11, Microsoft, Apple, CNN, Google and Facebook have appeared to us as celebratory examples of the willingness and ability of the US to overcome the distance and the absence through so-called modern progress of transportation and communication. Undoubtedly, the imaginary and the instrumental power associated to transports and communication of the last century and a half are identified with the mental images that the world has of the US. A world that has eagerly imported and copy their technology and technological culture. Beyond the illusions, this attempting, which has always been praised to transcende space and eclipse the time to get to places and peole increasingly distant and fast, has always a dark side: the political control of population, commercial advertising, the spread of the rumors, noise and gossip. However, since at least the nineteenth century, the political project incorporated in modern transportation and communication technologies was not shared by some of the most remarkable thinkers in the US not only in that century, but also in the 20th century. This paper begins by rescue Ralph W. Emerson and Henry D. Thoreau legacy regarding to communication. Emerson conceived communication as a give-and-take with no coordination between the two, and does not involve contact with the other. Thoreau, in turn, argued that modern trasnportation and communications inventions are but pretty toys which distract attention from serious things, nothing more than 'improved means to an end that is not perfected.' Secondly, we show that this skeptical view of the techological improvement of transport and communication was proceed in an original way with James W. Carey, a media studies thinker who became known for his criticism of the transmission view of communication.

Digital radiology and Picture Archiving and Communication System (PACS)

Plain radiography still accounts for the vast majority of imaging studies that are performed at multiple clinical instances. Digital detectors are now prominent in many imaging facilities and they are the main driving force towards filmless environments. There has been a working paradigm shift due to the functional separation of acquisition, visualization, and storage with deep impact in the imaging workflows. Moreover with direct digital detectors images are made available almost immediately. Digital radiology is now completely integrated in Picture Archiving and Communication System (PACS) environments governed by the Digital Imaging and Communications in Medicine (DICOM) standard. In this chapter a brief overview of PACS architectures and components is presented together with a necessarily brief account of the DICOM standard. Special focus is given to the DICOM digital radiology objects and how specific attributes may now be used to improve and increase the metadata repository associated with image data. Regular scrutiny of the metadata repository may serve as a valuable tool for improved, cost-effective, and multidimensional quality control procedures.

Cultural organizations and communication in portuguese decentralization policy

This paper intends to show the Portuguese municipalities’ commitment, since the first decade of this century, in cultural facilities of municipal management and how it provided 12 of the 18 district capitals of mainland Portugal with cultural equipment, but after all we want to know if this effort resulted in a regular, diverse, and innovative schedule. Investing in urban regeneration, local governments have tried to convert cities’ demographic changes (strengthening of the most educated and professionally qualified groups) in effective cultural demands that consolidate the three axes of development competitiveness-innovation-creativity. What the empirical study to the programming and communication proposals of those equipment shows is that it is not enough to provide cities with facilities; to escape to a utilitarian conception of culture, there is a whole work to be done so that such equipment be experienced and felt as new public sphere. Equipment in which proposals go through a fluid bind, constructed through space and discourse with local community, devoted a diversified and innovative bet full filling development axis. This paper presents in a systematic way what contributes to this binding on the analyzed equipment.

Cultural organizations and communication in portuguese decentralization policy

RFID together with multi-agent systems to control global value chains

Nowadays, the cooperative intelligent transport systems are part of a largest system. Transportations are modal operations integrated in logistics and, logistics is the main process of the supply chain management. The supply chain strategic management as a simultaneous local and global value chain is a collaborative/cooperative organization of stakeholders, many times in co-opetition, to perform a service to the customers respecting the time, place, price and quality levels. The transportation, like other logistics operations must add value, which is achieved in this case through compression lead times and order fulfillments. The complex supplier's network and the distribution channels must be efficient and the integral visibility (monitoring and tracing) of supply chain is a significant source of competitive advantage. Nowadays, the competition is not discussed between companies but among supply chains. This paper aims to evidence the current and emerging manufacturing and logistics system challenges as a new field of opportunities for the automation and control systems research community. Furthermore, the paper forecasts the use of radio frequency identification (RFID) technologies integrated into an information and communication technologies (ICT) framework based on distributed artificial intelligence (DAI) supported by a multi-agent system (MAS), as the most value advantage of supply chain management (SCM) in a cooperative intelligent logistics systems. Logistical platforms (production or distribution) as nodes of added value of supplying and distribution networks are proposed as critical points of the visibility of the inventory, where these technological needs are more evident.

A Service Integration Platform for Collaborative Networks

Integrated manufacturing constitutes a complex system made of heterogeneous information and control subsystems. Those subsystems are not designed to the cooperation. Typically each subsystem automates specific processes, and establishes closed application domains, therefore it is very difficult to integrate it with other subsystems in order to respond to the needed process dynamics. Furthermore, to cope with ever growing marketcompetition and demands, it is necessary for manufacturing/enterprise systems to increase their responsiveness based on up-to-date knowledge and in-time data gathered from the diverse information and control systems. These have created new challenges for manufacturing sector, and even bigger challenges for collaborative manufacturing. The growing complexity of the information and communication technologies when coping with innovative business services based on collaborative contributions from multiple stakeholders, requires novel and multidisciplinary approaches. Service orientation is a strategic approach to deal with such complexity, and various stakeholders' information systems. Services or more precisely the autonomous computational agents implementing the services, provide an architectural pattern able to cope with the needs of integrated and distributed collaborative solutions. This paper proposes a service-oriented framework, aiming to support a virtual organizations breeding environment that is the basis for establishing short or long term goal-oriented virtual organizations. The notion of integrated business services, where customers receive some value developed through the contribution from a network of companies is a key element.

Brincadeira: marcos temporais e memória

A brincadeira, expressão maior das culturas lúdicas da infância e do saber popular infantil que colora o folclore das crianças e que entre elas constitui prática singular, tem marcos temporais indeléveis que lhe (de)marcaram um tempo e que a memória guardou para sempre. A linearidade que, durante quase todo o tempo antes da chegada da TV, a brincadeira transportou, a revolução das suas práticas que a partir daí se operou e acentuou com a chegada das novas tecnologias da comunicação e informação à vida das crianças e a consequente transformação radical do seu habitus lúdico (da rua para casa e daqui para o quarto) balizam eras distintas de tempos sociais paralelas às que ditaram, consequentemente, a transformação que as artes de e para brincar foram, historicamente, sofrendo. Ao resgatar a brincadeira pela voz das crianças, muitas das vezes expressa pela voz dos adultos que hoje são, faz-se o registo, que neste artigo se guarda, de um pedaço da herança cultural lúdica que foi passando entre as quatro gerações que estudamos qualitativamente a partir de entrevistas grupais feitas em contexto familiar, que serviram de base para o que a seguir fica relatado. A brincadeira e a parafernália que a acompanha fazem parte da história de vida de todos nós e, por isso, a cada um cabe velar para que nunca pereça.

O livro na passagem de “átomos” a “bits”: as tecnologias digitais no contexto do livro electrónico

As Tecnologias de Informação e Comunicação colocam em debate o modo de pensar e olhar o livro tradicional e originam novas materialidades para o texto e novas formas, espaços e géneros de leitura. A revolução originada por Gutenberg democratizou o acesso ao livro tradicional, alterando os processos de acesso ao conhecimento. As tecnologias eletrónicas trouxeram consigo uma nova revolução, virtualizando o acesso aos textos que alteraram a paisagem da cultura clássica do livro. Recorrendo à ideia original do investigador Nicholas Negroponte, pretende-se realizar uma análise das alterações que o livro sofreu, enquanto objeto de suporte ao texto, na sua passagem para contextos digitais ou na passagem de “átomos” para “bits”.
