Frames for concepts

"A bizarre situation is the inadequacy of accepted principles regarding the setting of value of information. In spite of decades of serious usage and experience, there is no established view of economic calculation concerning information and IT-based systems." Falkenberg, E. W. Hesse P. Lindgreen B.E.

Rapid ethnography

Millen, D. R. (2000). Rapid ethnography: time deepening strategies for HCI field research. In Proceedings of the Conference on Designing interactive Systems: Processes, Practices, Methods, and Techniques. D. Boyarski and W. A. Kellogg, Eds. DIS '00. ACM Press, New York, August 17 - 19, 2000, pp. 280-286:
"Due to increasingly short product realization cycles, there has been growing interest in more time efficient methods, including rapid prototyping and various usability inspection techniques. This paper will introduce "rapid ethnography," which is a collection of field methods intended to provide a reasonable understanding of users and their activities given significant time pressures and limited time in the field. The core elements include limiting or constraining the research focus and scope, using key informants, capturing rich field data by using multiple observers and interactive observation techniques, and collaborative qualitative data analysis. A short case study illustrating the important characteristics of rapid ethnography will also be presented."

Desenvolvimento de Sistemas de Informação

DSI vs D Aplicações Informáticas VS D Organizacional:
"Desenvolvimento de sistemas de Informação é uma actividade de intervenção organizacional que inclui o Desenvolvimento de aplicações informáticas. Por sua vez, o Desenvolvimento Organizacional é também uma actividade de intervenção organizacional de âmbito mais alargado que poderá englobar o Desenvolvimento de Sistemas de Informação.

As figuras DSI.jpeg, DAI.jpeg, DO.jpeg e também as figuras DSIx.jpeg, DAIx.jpeg e DOx.jpeg ilustram as diferenças entre estas 3 actividades."

mobile ICT and effect on information overload

Above model in Allen, D.K. & Shoard, M. (2005). Spreading the load: mobile information and communications technologies and their effect on information overload . Information Research, 10(2), paper 227:

"The main finding of this research, however, is that personal information management is now distributed more evenly throughout the day. (...) In other respects, however, mobile technologies have created a paradox: information anxiety can be both lessened and fuelled. Anxiety may be eased by virtue of being always connectable, but this may further reinforce the need to be continually contactable. Furthermore, anxiety may be increased by the temptation to continually check or answer messages and through the need to clarify the meaning of shorter or ambiguous messages."

ICT

ICT - Information and Communication Technologies

Under the FP7 Research, ICT is the term used to encompass research that includes:
  1. Pervasive & Trusted Network & Service Infrastructures
  2. Cognitive Systems, Interaction, Robotics
  3. Components, Systems, Engineering
  4. Digital Libraries and Content
  5. Towards Sustainable & Personalised Healthcare
  6. ICT for Mobility, Environmental Sustainability and Energy Efficiency
  7. ICT for Independent Living and Inclusion
Although they do not define it explicitly in the EU glossaries, saying only what the acronym means (information and communication technologies).

Results for define: ICT are heterogeneous and do not offer help on the discussion of ICT versus IT. This last one (IT) seems to me to simplify that communications, namely the infrastructures needed, are not acknowledge.

In Portugal the acronym TIC (ICT) is widely used and seems to be accepted as is. According to the Glossário da Sociedade da Informação, da APDSI:
"tecnologias da informação, s.f.pl. [abrev. TI]
[en.] information technologies [abrev. IT]
[def.] Tecnologias necessárias para o processamento da informação ou, mais especificamente, o hardware e o software utilizados para converter, armazenar, proteger, tratar, transmitir e recuperar a informação, a partir de qualquer lugar e
em qualquer momento.
Nota: Embora nesta definição esteja incluída a componente de comunicação da informação, os desenvolvimentos actuais do multimédia e das telecomunicações, designadamente as redes de comp utadores e em especial a Internet, levaram à adopção generalizada do termo “tecnologias da informação e comunicação (TIC)”.
[v.tb.] tecnologias da informação e comunicação

tecnologias da informação e comunicação, s.f.pl. [abrev. TIC]
[en.] information and communication technologies [abrev. ICT]
[def.] Integração de métodos, processos de produção, hardware e software, com o objectivo de proporcionar a recolha, o processamento, a disseminação, a visualização e a utilização de informação, no interesse dos seus utilizadores.
[v.tb.] tecnologias da informação, telemática"

[Side note: recuperar discussão sobre um dos axiomas da comunicação «One cannot not Communicate», from Pragmatics of Human Communication: a study of interactional patterns, pathologies, and paradoxes (1967), Paul Watzlawick, Janet Helmick Beavin, & Don Jackson. A versão de que disponho é da Editora Cultrix, São Paulo, e a discussão deste axioma encontra-se nas pp. 44-47]

PS [13/Feb/2007] - While looking more deeply into ICT indicators (since i need them for SINCT project) came across this definition from the ITU Core ICT Indicators:
"It should be noted that this definition results in a broad interpretation of an ICT good and therefore an extensive classification. For output purposes, it is suggested that detailed categories be aggregated into the five broad categories recommended in the OECD paper, that is, telecommunications equipment, computer and related equipment, electronic components, audio and video equipment and other ICT goods.

It should also be noted that software products (including packaged software) are not included in this classification." (p. 42)
So, according to this document, ICT can be further explored in «goods» and «services»

From the OECD Guide to Measuring the Information Society (ver questionário pp. 116-129):
"(...) ICTs are general purpose technologies that can be used for a broad range of everyday activities." (p.11)

"“ICT goods must either be intended to fulfil the function of information processing and communication by electronic means, including transmission and display, or use electronic processing to detect, measure and/or record physical phenomena, or to control a physical process” (pp.88-89)

digital libary as information space

Recolhidas pela Interactive Learning with a Digital Library in Computer Science, uma compilação de definições para biblioteca digital. A noção de «espaço de informação» está implícita nesta descrição de Edward A. Fox (1999):
"Digital libraries are complex data/information/knowlege (hereafter information) systems that help: satisfy the information needs of users (societies), provide information services (scenarios), organize information in usable ways (structures), manage the location of information (spaces), and communicate information with users and their agents (streams)."
