This article describes research to build an embodied conversational agent as an interface to a question-and-answer system about a National Science Foundation program. We call this ECA the LifeLike Avatar, and it can interact with its users in spoken natural language to answer general as well as specific questions about specific topics. In an idealized case, the LifeLike Avatar could conceivably provide a user with a level of interaction such that he or she would not be certain as to whether (...) he or she is talking to the actual person via video teleconference. This could be considered a extended version of the seminal Turing test. Although passing such a test is still far off, our work moves the science in that direction. The Uncanny Valley notwithstanding, applications of such lifelike interfaces could include those where specific instructors/caregivers could be represented as stand-ins for the actual person in situations where personal representation is important. Possible areas that come to mind that might benefit from these lifelike ECAs include health-care support for elderly/disabled patients in extended home care, education/training, and knowledge preservation. Another more personal application would be to posthumously preserve elements of the persona of a loved one by family members. We apply this approach to a Q/a system for knowledge preservation and dissemination, where the specific individual who had this knowledge was to retire from the US National Science Foundation. The system is described in detail, and evaluations were performed to determine how well the system was perceived by users. (shrink)

The proposed memory architecture by Barzykowski and Moulin is compelling, and could be improved by incorporating a rational analysis of the functional roles of involuntary autobiographical memory and déjà vu. Additionally, modeling these phenomena computationally would remove ambiguities from the proposal. We provide examples of past work that illustrate how the phenomena may be described more precisely.

This article continues from where the author's 2008 book The Meaning of Video Games concluded and concerns what he learned from playing the simulation game Spore by Sims-creator Will Wright, especially the extent to which a social-network model had become during the development process the infrastructural backbone of the game. Spore's approach to the problem of building an asynchronous content-creation and content-sharing system aligned the video game with the most important trends in text-based digital humanities scholarship today. Thus this article (...) compares video games and digital texts, not in terms of their supposedly shared narrative content (not in terms of their content at all) but, rather, formally—in terms of how they model complex systems, how both video games and digital-text environments work by creating networked environments for the production, reproduction, transmission, and reception (indeed for the continual reediting) of their respective content-objects. Both texts and video games are systems, with their own special affordances and constraints, that provide both “spores” and “spurs,” seeds and provocations, prompts for new performances of meaning.

This essay introduces a Common Knowledge symposium on the relationship between texts (for instance, musical scores or dramatic scripts) and performance in the arts by drawing out its implications for the interpretation of publicly consequential texts (such as constitutions, legal statutes, and canon law). Arguing that judges and clerics could learn much from studying the work of Philip Gossett and other practitioners of textual criticism in the arts, the essay suggests that a wider array of choices exists for legal interpretation (...) than the usual alternative between originalism or literalism, on the one hand, and intuitionism, on the other hand. Contributions to the symposium (titled “Between Text and Performance”) emphasize what Roger Moseley calls “improvisatory fluency in historical idioms,” and this introduction recommends that jurists develop for the law the kind of “ear” that musicians must have when a score invites or demands improvisation.

This article names some of the human under standings and ways of being that are fundamental to teaching and learning, which new educational tech nologies, especially the computer, tend to remake, reduce, or replace altogether in K-12 classrooms. The article asks questions and tells stories about students, teachers, and the authors themselves using computers for educational purposes, investigating three particular uses of technology in detail. The authors argue that new educational technologies change the meaning of words common to teachers' vocabularies, (...) especially words such as classroom community, knowing, and coming to know. The authors also argue that human senses used in learning are nullified, if not assaulted, by new educational technologies. (shrink)

This article traces how students are represented in undergraduate prospectuses from 1998 to 2021 by employing a corpus-assisted approach to critical discourse analysis of a 1.9 million word corpus of prospectuses from a single Russell Group university in England. Recent decades have witnessed an increase in tuition fees and competition to attract students; hence, it is important to understand to what extent, if any, the representation of students has changed in the prospectuses. Our findings add to the literature by showing (...) for the first time that the representation of students in prospectuses has shifted in ways consistent with the impact of market-driven policy on the sector. Initially, students were positioned primarily as learners, partners to the university, and members of a community. Latterly, students are positioned primarily as consumers and future professionals. These findings are significant because they capture the extent to which a market-driven agenda has been normalised by institutions, and demonstrate how this process of normalisation occurs. Even before they reach campus, young people are conditioned and defined by the market, with the prospectus presenting university as an opportunity to enhance earning power rather than to benefit from life-changing education.
