Visions of single information space

Tom Heath and Christian Bizer (2011) Linked Data: Evolving the Web into a Global Data Space (HTML edition). Synthesis Lectures on the Semantic Web: Theory and Technology, 1:1, 1-136. Morgan & Claypool:
"The World Wide Web has enabled the creation of a global information space comprising linked documents. (...) Linked Data provides a publishing paradigm in which not only documents, but also data, can be a first class citizen of the Web, thereby enabling the extension of the Web with a global data space based on open standards - the Web of Data."

"Just as hyperlinks in the classic Web connect documents into a single global information space, Linked Data enables links to be set between items in different data sources and therefore connect these sources into a single global data space."

Indústria do Papel

from CEPI

Na Europa, CEPI (Confederation of European Paper Industries) nas Preliminary Stats for 2010 registam aumentos, comparativamente a 2009, apesar da situação macroeconómica. Para estatísticas específicas de papel destinado a impressão, ver CEPIPRINT (Association of European Publication Paper Producers) e CEPIFINE (Confederation of European Fine Paper Industries).

Em portugal, CELPA (Associação da Indústria Papeleira) Boletim Estatístico 2009 (Setembro, 2010) os dados reportados a 2009, registaram aumento da produção em Portugal:
"Em 2009 a produção europeia de pastas para papel desceu 13,5%, sendo Portugal o 4º maior produtor europeu de pasta – com 7,1% do total – e o 3º maior produtor de pastas químicas – com 8,9% de produção. Relativamente à produção de papel, também a Europa viu a sua produção baixar 10,4%, sendo Portugal o 11º maior produtor europeu de papel e cartão – com 1,8% do total - e o 2º maior produtor de papel fino não revestido (UWF) – com 11,6% da produção total." (p.18)
"Neste contexto, em 2009 as empresas portuguesas produtoras de pasta e de papel conseguiram registar um aumento da produção de pastas virgens de 7,9%. (...) Apesar das quebras sentidas, com impacte directo na Rendibilidade das Vendas, que diminuiu de 10,2%, em 2008, para 7,0%, em 2009, o sector está a adaptar-se às mudanças dos mercados e acredita no seu potencial de crescimento a médio/longo prazo." (p.18-19)
Pena que na PORDATA não tenham dados sobre a produção de papel. Faltam-me também aqui estatísticas em termos globais que permitam ter uma noção do consumo de papel ao longo dos anos.

Opening the source(s) with blogs in research practices

By the time I've started my PhD, I had already used blogs as a research tool for conducting research work, since 2003 [master's degree in Information Studies] not so much as a fieldwork tool, but as a way of registering trails of the research (ongoing information, readings, questions, doubts, ...) that allowed others to  find me and, in turn, due to explicit (comments in blog) or implicit (link back, web bookmarks, citations) conversations allowed me to find them.

Lorenz antropologi.info blog, for long, as been a way for me to feel connected to anthropology developments. Yesterday, while re-reading a recent post about using Comics to present research findings, I've recalled an older post that offered the link to the issues of Opening the source in fieldwork:
"When you do anthropological fieldwork, your main tool is yourself. You participate, you observe and you ask incredible amounts of questions."
I would think this would apply equally well for everyone conducting social science research, either for qualitative or quantitative studies. If for the qualitative paradigm one might not find hard to extend the above citation, it might not be so straight forward for the quantitative research. But it might become clear if one thinks that in quantitative survey instruments, the questions are framed by the researcher, hence the researcher becomes part of the design tool.

Come to think in this terms, all of science is done this way. One of the big differences might be that in anthropological fieldwork the researcher explicitly exposes the self as part of the study (reflexivity) and in other paradigms the researcher is concealed from the reports/narratives of the research, but nevertheless, they are embedded in the research work... and I recall the work of Latour and Wolgar on Laboratory Life: the construction of scientific facts:
"The construction of scientific facts, in particular, is a process of generating texts whose fate (status, value, utility, facticity) depends on their subsequent interpretation."

Information as thing

In accordance with the view of information as thing by Buckland (1999), the article by Jones, W. (2010, No knowledge but through informationFirst Monday, vol. 15 (9-6), September) brings back the arguments of the need to operate/manage information items and not knowledge: "Knowledge is not a thing to be managed directly. Knowledge is managed only indirectly through information". His view is directed to show that Personal Knowledge Management (PKM) should be viewed as a subset o Personal Information Management (PIM) and not as a higher level approach. 
"The ways in which an item is manipulated will vary depending upon its form and the tools available for this form. The tools used for interaction with paper–based information items include, for example, paper clips, staplers, filing cabinets and the flat surfaces of a desktop. In interactions with digital information items, we depend upon the support of various computer–based tools and applications such as e–mail applications, file managers, Web browsers, and so on. (...) Knowledge as ‘no thing’ cannot be managed directly. If we think we have knowledge ‘at our fingertips’ we are most likely touching information in some form instead. This is not to say that knowledge management is not possible. But we do so through its expression in information. There is no management of knowledge except through the management of information."


In his paper he also evokes a pictorial representation of "[i]nformation management activities viewed as an effort to establish, use and maintain a mapping between needs and information. ["illustration was done by Elizabeth Boling and is a variation of a figure that first appeared in Jones (2008)."]

Could not help myself recalling the nonsense of 'knowledge management' by Tom Wilson (2002), which as always provoked great discussions and food for thought in my journey.

Technology interference in data collection, transcription and analysis

Another number of the Forum Qualitative Social Research is out, and although just gave a superficial reading to the table of contents and one of the contributions, the article by Jeanine Evers seem to answer some of my questions and issues when dealing with the huge amount of visual data (mainly photos) that I've collected for my research:
Evers, Jeanine C. (2011). From the Past into the Future. How Technological Developments Change Our Ways of Data Collection, Transcription and Analysis [94 paragraphs]. Forum Qualitative Sozialforschung / Forum: Qualitative Social Research, 12(1), Art. 38.
The whole issue is dedicated to «Discussions on Qualitative Data Analysis Software by Developers and Users», which should be of interest for many people doing qualitative research and/or developing technological tools for qualitative analysis, reporting «The KWALON Experiment»:
"The KWALON Experiment consisted of five developers of Qualitative Data Analysis (QDA) software analysing a dataset regarding the financial crisis in the time period 2008-2009, provided by the conference organisers. Besides this experiment, researchers were invited to present their reflective papers on the use of QDA software. This introduction gives a description of the experiment, the "rules", research questions and reflective points, as well as a full description of the dataset and search rules used, and our reflection on the lessons learned."

Europe Digital Agenda - The New Renaissance

"The report urges EU Member States to step up their efforts to put online the collections held in all their libraries, archives and museums. It stresses the benefits of making Europe's culture and knowledge more easily accessible. It also points to the potential economic benefits of digitisation (...) The report's recommendations will feed into the Commission's broader strategy, under the Digital Agenda for Europe, to help cultural institutions make the transition towards the digital age."
"Today europeana.eu already offers access to more than 15 million digitised books, maps, photographs, film clips, paintings and musical extracts, but this is only a fraction of works held by Europe's cultural institutions (see IP/10/1524). Most digitised materials are older works in the public domain, to avoid potential litigation for works covered by copyright."

simple recipe for a Merry Christmas

Merry Christmas...

Christmas is not about decorations, nor status, money, cars, pearls, technologies or the latest fashion like they try to tell you over and over again in radio, TV or Web advertisements... neither stress (a lot of it consumerism related!). 

Christmas is about reunions, gatherings. It's a time that allows us  meeting together with family and friends. It's sharing time together. The light motive can be a meal, a late supper (consoada), a xmas lunch, tea or dinner. Use your heart, your availability and your creativity to be together with family and friends. The rest? The rest are inventions of organizations that get rich by exploring your feelings through fabricated ideals of happiness and success. We can be smarter than them. Feelings come from the inside. They can not be bought and we know that.

Lets keep our heart together and let aside the trivial. Lets bring out those memory objects that have made up who we are, add your own personal touch with recycled things, invite someone home or go to someone else's house. Make your own cookies, jam, a bread loaf or your special sauce, and go knock on a neighbor's house, a long time friend, family members or a group of relief workers. Lets give the gift of time with our hearts right open. Lets have a merry Christmas!

EIF for EU

European Interoperability Framework for European Public Services (2010). In the annex of the report, they define interoperability as "(...) the ability of disparate and diverse organisations to interact towards mutually beneficial and agreed common goals, involving the sharing of information and knowledge between the organisations, through the business processes they support, by means of the exchange of data between their respective ICT systems."


Further ahead in the report, a reference to paper and face-to-face in the multichannel mix, caught my attention: "Inclusion and accessibility usually involve multichannel delivery. Traditional paper-based or face-to-face service delivery may need to co-exist with electronic delivery, giving citizens a choice of access."

Resoluções que extinguem

Vai fazer 4 anos que por Resolução do Conselho de Ministros n.º 124/2006 [Diário da República, Série I, de 2006-10-03] se anunciava a reviravolta do sistema dos laboratórios do Estado. Entre outras, lia-se no ponto 5, do anexo:
"É extinto o Instituto Nacional de Engenharia, Tecnologia e Inovação (INETI), sendo os seus recursos científicos e tecnológicos, humanos e materiais reorganizados e integrados noutros laboratórios, centros tecnológicos, instituições de ensino superior e consórcios a criar. Em particular, as infra-estruturas do INETI transformam-se em parque de ciência e tecnologia com a participação e gestão de universidades, laboratórios associados e laboratórios do Estado e alargam-se a parcerias com empresas, no quadro de projectos definidos, organizando-se ainda como espaço de acolhimento de programas europeus de I&D."
  • Para onde foram os «seus recursos científicos»?
  • E os «recursos tecnológicos»?
  • E os «recursos humanos»?
  • Onde está o «parque de ciência e tecnologia com a participação e gestão de universidades, laboratórios associados e laboratórios do Estado»?

Claro está que estas questões não interessam a ninguém. O que interessa não é cuidar das infra-estruturas e da estabilidade necessárias para que se faça ciência, mas sim ficar bem na fotografia e inscrever nas palavras as intenções de actos que nunca irão ver a luz do dia, tornando irreversíveis os danos causados.

Pelo meio, no decurso de 4 longos anos, foram-se perdendo unidades, recursos científicos e tecnológicos. As cerca de 1000 pessoas na altura? Umas foram resistindo, outras cedendo, depois sucumbindo, caindo ou tombando... reconvertendo horizontes científicos em reformas antecipadas, em trabalho administrativo, em fragmentos profissionais, em alternativas à ciência.  Foram-se esvaziando as competências, as capacidades e as equipas que outrora alimentavam e captavam recursos. Os que resistem são menos de 500. Sem novas admissões ou valorização dos que ficam.

O que se ganhou com estas perdas para se sentir que valeu (vale?) a pena: para o país, para a IeD, para o Laboratório, para as unidades, para as equipas e para os reflexos que se fizeram (fazem) sentir na vida de tantos colegas? Quatro anos de transição e a tal «reorganização» ainda por acabar...

[link para o post de 3 de Outubro de 2006, no B2OB: Não basta estar extinto!]

PS [2010, 11 de Outubro]: Recebi (através de um amigo atento) a indicação da publicação em Diário da República da "Lista de Reafectação do Pessoal do INETI ao LNEG". Afinal passámos de cerca de 1000  para 404 efectivos. Ou seja, em 3 anos uma redução de 60% no quadro de pessoal!

Distance (still) matters!

Olson, Gary M. and Olson, Judith S.(2000). Distance Matters. Human-Computer Interaction, vol. 15(2), pp.139-178.

Contradicting the idea that «Distance is Dead», and supporting with substantive theory in their study, Olson and Olson (2000) clearly show that technological mediated interactions will not completely substitute presence and co-located interactions, even with sophisticated technological use for work: "Distance is not only alive and well, it is in several essential respect immortal" ["(...) synthesized into four key concepts: common ground, coupling of work, collaboration readiness, and collaboration technology readiness"]

Generability in positivism and interpretivism

Como as questões da generalização continuam na ordem do dia (à mais de 100 anos!), esta entrada pode ser útil para mais pessoas dos sistemas de informação (SI), ou não ;)

Lee, A. S. and Baskerville, R. L. (2003). Generalizing generalizability in information systems research. Information Systems Research, 14(3), pp. 221-243:
"Although Yin’s case research method is considered to be positivist, his concept of analytical generalization has received attention and approval from a prominent interpretive IS researcher,Walsham (1995b). Walsham accepts Yin’s notion of generalizing to theory and extends it to four types of generalization. Walsham explains (pp. 70–80) that, beginning with the facts or the rich description of a case, the researcher can generalize to concepts, to a theory, to specific implications, or to rich insight. All four of Walsham’s examples involve generalizing from empirical statements (reflecting the observations made in a case study) to theoretical statements (concepts, theory ,specific implications,and rich insight).
Klein and Myers (1999) also recognize the process of generalizing from empirical statements to theoretical statements. Whereas they acknowledge that “interpretive research values the documentation of unique circumstances,” they also emphasize, “it is important that theoretical abstractions and generalizations should be carefully related to the case study details as they were experienced and/or collected by the researcher” They add: “The key point here is that theory plays a crucial role in interpretive research,and clearly distinguishes it from just anecdotes” (p. 75). For them,generalizing from idiographic details to theory is so important that they elevate it to one of their seven principles for assessing interpretive field work: The principle of abstraction and generalization."

semantics to pragmatics

Olsen et al (1998). Full Text Searching and Information Overload. The International Information & Library Review, vol. 30(2), pp. 105-122:
"While the tools for writing, storing, disseminating and retrieving documents have undergone a revolution in the last few decades, reading is still a very slow process. For practical reasons, we are forced to determine a working set size, i.e., the number of documents that we can handle."
(...) 
"By combining metadata and subject terms in a vector-based information space, visualization may give us the opportunity to handle larger document collections and to help the user to find the documents that are most likely to satisfy an information need defined on a pragmatic level."
