losses in «information transitions»: time, errors, sync

Example of information loss in «information transitions». Actual high mobility of healthcare workers to collect data on tuberculosis patients. IS applied research solution: capturing information (almost) directly to PDA. Still have to be entered by workers, but after collected through the PDA stays in digital form and is apt for transfer to other IS.
"Under the old patient tracking system, a team of four healthcare workers would visit more than 100 health care centers and labs twice a week to record patient test results on paper sheets. A couple of times a week, they returned to their main office to transcribe those results onto two sets of forms per patient -- one for the doctors and one for the health care administrators.

From start to finish, that process took an average of more than three weeks per patient. There was also greater potential for error because information was copied by hand so many times.

With the new system, health care workers enter all of the lab data into their handheld devices, using medical software designed for this purpose. When the workers return to their office, they sync up the PDAs with their computers.

mobility concept

Kakihara, M. and Sørensen, C. (2001). Expanding the 'mobility' concept. SIGGROUP Bull. 22, 3 (Dec. 2001), pp. 33-37:
"The train and airline infrastructures are highly integrated with ICTs such as electronic reservation systems and traffic control systems. It is therefore important to recognize that the fundamental nature of technological revolution in the late twentieth century is the dynamic and complex interplay between old and new technologies and between the reconfiguration of the technological fabric and its domestication (...).This paper concerns the concept of mobility, which manifests such a transformation of our social lives combining new and old technologies. It is now widely argued that our life styles have become increasingly mobile in the sense that the speed of transportation and hence geographical reach within a given time span is dramatically augmented by modern technological developments and sophistication such as train and airplane systems."

Multiple computer devices

Dearman, D. and Pierce, J. S. (2008). It's on my other computer!: computing with multiple devices. In Proceeding of the Twenty-Sixth Annual SIGCHI Conference on Human Factors in Computing Systems (Florence, Italy, April 05 - 10, 2008), pp. 767-776:
"The number of computing devices that people use is growing. To gain a better understanding of why and how people use multiple devices, we interviewed 27 people from academia and industry. From these interviews we distill four primary findings. First, associating a user's activities with a particular device is problematic for multiple device users because many activities span multiple devices. Second, device use varies by user and circumstance; users assign different roles to devices both by choice and by constraint. Third, users in industry want to separate work and personal activities across work and personal devices, but they have difficulty doing so in practice Finally, users employ a variety of techniques for accessing information across devices, but there is room for improvement: participants reported managing information across their devices as the most challenging aspect of using multiple devices. We suggest opportunities to improve the user experience by focusing on the user rather than the applications and devices; making devices aware of their roles; and providing lighter-weight methods for transferring information, including synchronization services that engender more trust from users."

(behind the) information made simple

Visual and voice translation of the History of the Internet: complex information made simple. Inspiring.



What we see is a finished product. Much more interesting was to see the amount of information required until the end product was done. In my work I would like to follow someone during all the phases that where needed to make this 8 minute video, looking to all the information used.

Distraction(s)...

... with artefacts that carry a lot of embedded tools and information within them.

Not so long ago (15 years), a PC would carry mainly a set of very restrictive production tools. Today we have a plethora of installed tools (and gadgets) available in our computers, and an open door (internet access) of millions of other available for us to play with and/or install.

How does this affect PIM? How distracted are we? Does this explain, for example, the difficulties of reading an entire PDF on the computer without interrupting to:
  • open another pdf
  • find papers from the same author
  • search database for (new concept found, .... ) before finishing the reading
  • ... constant switching between reading pdf and other (available/competing)  information
Are there gender differences in how these distractions affect PIM efforts? Do they have any relation to multitasking?

Gender self-perceived differences in digital literacy

Eszter Hargittai & Steven Shafer (2006). Differences in Actual and Perceived Online Skills: The Role of Gender. Social Science Quarterly, Vol. 87(2), pp. 432-448:
"Our data suggest that overall men and women do not differ significantly in their abilities to find various types of information online. However, we do find that women are much more likely to shortchange themselves when it comes to self-perception of their online skills. The gender effects appear to be significant with respect to self-perceived skill levels. Our findings are consistent with Correll’s (2001) work, which found that net of actual skills, young women are less likely to perceive themselves as skilled in these domains, which in turn biases their propensity to pursue math- and science-related careers. Similarly, we find that net of actual skills, women tend to rate their online skills lower than do men. Women’s lower self-assessment vis-a-vis web-use ability may affect significantly the extent of their online behavior and the types of uses to which they put the medium." (p. 444)

I wonder if this self-perceived skill differences between gender also aply to other skills beyond digital literacy (by David Bawden). For instance, when building their own resumes (CV) do women also shortchange their skills?...

ICT changing the meaning of being «at work»

"Nomadic use of ICT will challenge the meaning of ‘at work’ Nomadicity will make work patterns less fixed in time and space. This will create major challenges for both employers and employees. Making working life and education more sustainable in terms of working and studying from home intensifies the need for realising the nomadicity that ICT can provide."

On scrapnotes and «technologizing» everything

Scrapings or information scraps are little notes that we take in a paper cloth table in a restaurant, a napkin, a post-it, the corner of a magazine or the newspaper, a notebook, but also in del.icio.us bookmarks, text files or whatever is at hand, at the moment.

Maybe the clue to understand scrapings lies not in developing new tools to add to the mash and proliferation of our bits of information, but in understanding that they are part of our own information behaviours for what works in given occasions. For me it seems more relevant to acknowledge it, and incorporate it as a practice that works for individuals, than to see it as a problem that needs a technological solution.

Scrapings are immediate. One takes note of it, with what one has at hand, and makes it immediately available to add meta data to a book we are reading, to glue at the fridge as a reminder or a grocery list that we later take with us, to note down a telephone or the name of the music passing on the radio, a research lead for later reflection, a visual signal, a temporary mark, making eliciting annotations on a paper we are reading, a drawing to complex or simple ideas. 

Imagine the time (and problems)  it would take for you to make a «simple» scraping in a web application (hardware + internet access + application initiation) while at the supermarket, talking with a colegue on the corridor, having a meal with friends, while driving (or stopping endlessly in IC19 ;)... 

Ever notice that in a rush moment, although people have their latest technology mobile phones, in order to exchange contacts either they jot down the contact in a piece of paper, or exchange presentation cards, or they dial the number they are given to stay with that record (and confirm they have noted the number correctly) and only later (if ever) they add more information to the plenty of available labels to fill in their sophisticated «contact managers»? 

Let alone the transferability and malleability of such notes, in the end is also about reliability. How many of us have lost your long time acquired contact details due to loss, robbery or malfunction of your telephones (or whatever gadget you used)? How many of us will be able to show our present pictures to our future grandchildren (even with all the available storing capacity, gadgets and backup practices)?... 

Makes us think about why with so many available technologies, with all the digital facilities that we have, paper production does not seem to be slowing down and the once envisioned «digital office» couldn't look further apart as paper seems to be the most reliable medium in our PIM (personal information management) practices. Maybe paper is still our long lasting backup and not the other way around.

For a deeper knowldge about scraping, there is a lot to reflect in the Haystack Group of MIT. See also tool: List.it and protocol for conducting observations for interested users.

scattered data among artifacts

pulverized data for my research across different tools and plataforms in need of aggregation for my research:
  • citeUlike - tool used for biblioghraphic collection. Problems encountered through time concern: a) not having access to some of the publications but able to keep reference; b) duplicated items due to encounters in different databases; c) limited or unavailable internet access interfere with information management practices
  • infotransitions - tool for embedding other tools, work-in-progress, active links, communication with supervisor, thoughts, reflextions & draft writings. Problems encountered through time: a) limited or unavailable internet access interfere with information work behaviour & PIM practices; b) private space does not allow for interactions with peers or people exploring/interested in same topics; c) althought meant as a way for «being» in permanent contact with supervisor, allowing him to «observe» recent research concerns, it's barely used as such
  • del.icio.us - started to use this tool to allow my «favorites» to be computer independent, and later to help manage team search efforts for project work. Problems limited to unavailable internet access that temper with access and PIM practices.
  • flickr - Although my main photos & picture are locally stored (my computer, moveable hard drive .... (...)
  • notebooks - one of the most stable practices I have since I made my first research attemps (back in 1999, expatriation cycle, IPL/ESCS. During the changes that occured in this last year in my working infrastructures (uncertain internet access, reduce mobility & communications due to financial constrains and disapeering workplace & homeplace), I used my notebooks and rely on them much more then before (for noting my private research notes I was using this blog, wich I used also to illicite all the other web spaces I use (wrote above). As a tool it's very portable, no need interfaces to access content, no re-charging needs, it's not an intruder, I can carry it with me all the time. On the negative aspects are the finite space available and the inherited need to change notebooks once I use the last page. The transition for a new book brings me the need to carry during some time 2 notebooks with me... and finding past notes is not always quick. Moving the notes to text adds also aditinal work.
Databases used with existing individual accounts and resources stored at their sites, also add to the pulverization:
  • citeseerX (a free scientific database, focusing primarily on the literature in computer and information science)
  • myACM (2 years paid subscription, focusing primarely on computer sciences and dessiminating practices)
  • Wiley (group publisher, aggregates diverse publishing materials from diferent areas of research)
  • LibraryThing (some of my personal books with interface for my Amazon aquisitions & account)
  • [stopped using b-on because I could not store my papers in there, only queries, and also because of problems with exporting found results... and because there are other places I can use to accomplish the job]

(antecipating) Place in mobile work

Brown, B. and O’Hara, K. (2003). Place as a practical concern of mobile workers. Environment and Planning, A 35, pp. 1565–1587:
"Mobile workers often need to configure their activies to take account of the different places they find themselves. This can involve considerable ‘juggling’ of their plans, humble office equipment, and their co-workers. In turn mobile workers change places, as they appropriate different sites for their work. Specifically, technology allows for the limited re-appropriation of travel and leisure sites as places for work (such as trains and cafés). Time is also an important practical concern for mobile workers. While mobile work may be seen as relatively flexible, fixed temporal structures allow mobile workers to ‘accomplishment synchronicity ’ with others."

"(...) a broadened view of how we might undertake personal digital archiving, both broadly (for consumers) and more narrowly (for academics, scholars, researchers, and students); some of these issues may also carry over into the realm of institutional archiving, although that is not my aim."
