Using language technologies to support individual formative feedback

In modern educational environments for group learning it is often challenging for tutors to provide timely individual formative feedback to learners. Taking the case of undergraduate Medicine, we have found that formative feedback is generally provided to learners on an ad-hoc basis, usually at the group, rather than individual, level. Consequently, conceptual issues for individuals often remain undetected until summative assessment. In many subject domains, learners will typically produce written materials to record their study activities. One way for tutors to diagnose conceptual development issues for an individual learner would be to analyse the contents of the learning materials they produce, which would be a significant undertaking. CONSPECT is one of six core web-based services of the Language Technologies for Lifelong Learning (LTfLL) project. This European Union Framework 7-funded project seeks to make use of Language Technologies to provide semi-automated analysis of the large quantities of text generated by learners through the course of their learning. CONSPECT aims to provide formative feedback and monitoring of learners’ conceptual development. It uses a Natural Language Processing method, based on Latent Semantic Analysis, to compare learner materials to reference models generated from reference or learning materials. This paper provides a summary of the service development alongside results from validation of Version 1.0 of the service

The objectness of everyday life: disburdenment or engagement?

The article grew out of a conference paper, ‘The objectness of everyday life: engagement and disburdenment’, Material Geographies, UCL, September 2002. An expanded version of the paper was included in a special themed section of an issue of Geoforum. The paper intervenes into contemporary philosophical scholarship on the nature of use-value, usability, design and ethics. The article has been directly engaged with in an academic journal; Christensen, Carleton B. (2005) ‘The Material Basis of Everyday Rationality: transformation by design or education?’, Design Philosophy Papers No.4,)

Knowledge society arguments revisited in the semantic technologies era

In the light of high profile governmental and international efforts to realise the knowledge society, I review the arguments made for and against it from a technology standpoint. I focus on advanced knowledge technologies with applications on a large scale and in open- ended environments like the World Wide Web and its ambitious extension, the Semantic Web. I argue for a greater role of social networks in a knowledge society and I explore the recent developments in mechanised trust, knowledge certification, and speculate on their blending with traditional societal institutions. These form the basis of a sketched roadmap for enabling technologies for a knowledge society

Forms of Naturalism in Seminal Neoclassical Texts: An Analysis and Comparison of Léon Walras, John Bates Clark, and William Stanley Jevons

At issue here is the role of “naturalism” in certain seminal neoclassical texts. I outline both a positive and normative dimension to the term “naturalism.” Along its positive dimension, I use the term to mean that the social sciences ought to follow the method of the natural sciences. Along its normative dimension, I use it to mean that the natural order of things can provide for justice. I examine the role these concepts play in the works of Léon Walras, John Bates Clark, and William Stanley Jevons. The question I raise, through this examination, is whether the positive conception of naturalism eclipses possibilities of economic transformation, thereby undermining any coherent normative evaluation of whether a purportedly natural (i.e. unchangeable) set of economic facts or laws is “just.” Walras argues that “economics” should be modelled on the natural sciences, and that value-in-exchange is natural. Simultaneously, Walras claims that economic institutions are “artificial.” He arrives at the former claim, I argue, because he believes that only by seeing economic laws and facts as “natural” can he demonstrate that they necessarily obtain; the latter claim is motivated by a desire to evaluate economic institutions normatively. This leads Walras into a contradiction, I argue, insofar as the former claim undermines the latter. Clark, initially, seems to avoid Walras’ contradiction, insofar as he refers to economic laws as social, not natural. However, Clark’s distinction between the social and natural is superficial, insofar as the social is conceptualized purely as a function of the natural. Clark does not imagine that the specifically social character of economic laws might transform the “natural.” Further, for Clark, the natural not only shapes the social (economic) in a positive sense, it also renders economic laws just. But, like Walras, Clark’s normative evaluation is undermined by his insistence on a fundamentally natural predicate for his economic laws. For Jevons, like Walras, economics is properly modelled on the natural sciences, and, in particular, on the science of mechanics. Jevons then chooses to mechanize the economic agent itself, which, I argue, undermines any conception of human transformation of the surrounding “economy.

Emotional Biosensing: Exploring Critical Alternatives

Emotional biosensing is rising in daily life: Data and categories claim to know how people feel and suggest what they should do about it, while CSCW explores new biosensing possibilities. Prevalent approaches to emotional biosensing are too limited, focusing on the individual, optimization, and normative categorization. Conceptual shifts can help explore alternatives: toward materiality, from representation toward performativity, inter-action to intra-action, shifting biopolitics, and shifting affect/desire. We contribute (1) synthesizing wide-ranging conceptual lenses, providing analysis connecting them to emotional biosensing design, (2) analyzing selected design exemplars to apply these lenses to design research, and (3) offering our own recommendations for designers and design researchers. In particular we suggest humility in knowledge claims with emotional biosensing, prioritizing care and affirmation over self- improvement, and exploring alternative desires. We call for critically questioning and generatively re- imagining the role of data in configuring sensing, feeling, ‘the good life,’ and everyday experience

Congratulations, you\u27re pre-approved! : an analysis of credit limit upselling letters

Consumer Action commissioned Dr Paul Harrison, Deakin Business School, Deakin University and Marta Massi, School of Marketing and Communication, Lumsa University (Rome), to study the psychological aspects of one form of credit marketing – unsolicited credit card limit-increase offers (UCCLIOs). The researchers studied 21 UCCLIO letters – 17 provided by consumers and four provided by banks – and applied theories developed from previous research in the fields of marketing, consumer behavior, behavioural economics and cognitive psychology, to describe likely ways in which UCCLIO’s influenced consumer behavior and decision making. The researchers make some recommendations from a behavioural perspective based on their findings, and Consumer Action proposes how these findings might be applied to consumer policy
