Artists, audience and participations

We spent a fare amount of time thinking and debating where to draw the line between what is and what is not single-screen-based interactive media. This really is a tricky category. I would like to use this opportunity to raise certain issues about this very new category introduced this year to ifva. First of all, what do we mean by "interactive" media? If we conceptually or philosophically try to describe it, almost every artifact (not only those who are intended as a piece of art) can be perceived as "interactive" media as soon as one sees/ recognises it and begins interacting with it physically and/or mentally. What about when we limit this to computer related media? This certainly limits the scope, but well, it is becoming increasinly difficult to find art and design that are considered innovative without the use of computer. the term "single-screen" certainly makes it more specific, but as we saw from a range of works submitted to this category, people do come up with various interpretations to it. Some simply submitted work that can be viewed with computer screen, which didn't allow much user participation, while others provided various degrees of user/audience participation. What does "singel-screen-based interactive media" mean?

Losing their marbles : syntax-free programming for assessing problem-solving skills

Novice programmers have difficulty developing an algorithmic solution while simultaneously obeying the syntactic constraints of the target programming language. To see how students fare in algorithmic problem solving when not burdened by syntax, we conducted an experiment in which a large class of beginning programmers were required to write a solution to a computational problem in structured English, as if instructing a child, without reference to program code at all. The students produced an unexpectedly wide range of correct, and attempted, solutions, some of which had not occurred to their teachers. We also found that many common programming errors were evident in the natural language algorithms, including failure to ensure loop termination, hardwiring of solutions, failure to properly initialise the computation, and use of unnecessary temporary variables, suggesting that these mistakes are caused by inexperience at thinking algorithmically, rather than difficulties in expressing solutions as program code.

A time-variant medical data trustworthiness assessment model

Electronic Health Record (EHR) systems are being introduced to overcome the limitations associated with paper-based and isolated Electronic Medical Record (EMR) systems. This is accomplished by aggregating medical data and consolidating them in one digital repository. Though an EHR system provides obvious functional benefits, there is a growing concern about the privacy and reliability (trustworthiness) of Electronic Health Records. Security requirements such as confidentiality, integrity, and availability can be satisfied by traditional hard security mechanisms. However, measuring data trustworthiness from the perspective of data entry is an issue that cannot be solved with traditional mechanisms, especially since degrees of trust change over time. In this paper, we introduce a Time-variant Medical Data Trustworthiness (TMDT) assessment model to evaluate the trustworthiness of medical data by evaluating the trustworthiness of its sources, namely the healthcare organisation where the data was created and the medical practitioner who diagnosed the patient and authorised entry of this data into the patient’s medical record, with respect to a certain period of time. The result can then be used by the EHR system to manipulate health record metadata to alert medical practitioners relying on the information to possible reliability problems.
