System Performance and Natural Language Expression of Information Needs

Consider information retrieval systems that respond to a query (a natural language statement of a topic, an information need) with an ordered list of 1000 documents from the document collection. From the responses to queries that all express the same topic, one can discern how the words associated with a topic result in particular system behavior. From what is discerned from different topics, one can hypothesize abstract topic factors that influence system performance. An example of such a factor is the specificity of the topic's primary key word. This paper shows that statements about the effect of abstract topic factors on system performance can be supported empirically. A combination of statistical methods is applied to system responses from NIST's Text REtrieval Conference. We analyze each topic using a measure of irrelevant-document exclusion computed for each response and a measure of dissimilarity between relevant-document return orders computed for each pair of responses. We formulate topic factors through graphical comparison of measurements for different topics. Finally, we propose for each topic a four-dimensional summarization that we use to select topic comparisons likely to depict topic factors clearly.     

Building preservation functionality in a digital archive: the National Library of The Netherlands

An increasing volume of information exists only in digital form. It can be scanned material; material actually created as digital publications; or material created as part of the day‐to‐day business of an organization. In The Netherlands, initiatives such as the ‘Memory of The Netherlands’ have emerged, creating a demand for good‐quality digital materials to support them. Many other digitization initiatives are constantly being announced. The digital form offers many advantages but presents challenges in respect of preservation and of changes in platforms and software.

Making friends in the ‘electronic student lounge’

An important characteristic of computer conferencing in the context of distance teaching is that there is no requirement for all participants to interact at the same time. Individual users can participate at times which suit them. In an educational context, computer conferencing can provide for a variety of interactions between students, and between students and teaching staff. The .’electronic student lounge’ is a conference for socialising, for making friends, and for forming special interest groups. The 1989 extramural telecommunications (EXTEL) project at Massey University, New Zealand, provided a group of Computer Science students with such a facility. The project was based on an innovative, cheap, easy‐to‐use electronic messaging system developed at Massey.

This paper describes the EXTEL project, including the messaging system employed and the data gathering methods used to evaluate it. An analysis is presented of a sample of the more than 2000 messages exchanged over the trial period. The results of surveys of the participating students both before and after the trial are also presented. A significant proportion of the interactions were found to consist of ‘general chat’ thus supporting the notion that this type of facility helps reduce the isolation often experienced in distance teaching.

Representations of childcare in the Australian print media: An exploratory corpus-assisted discourse analysis

While an increasing body of Australian and international research has explored the relationship between media and education, few studies have examined this relationship in the context of early childhood education. This paper contributes to this research gap by reporting on a corpus-assisted discourse analysis of how childcare is represented in 801 newspaper texts from six Australian newspapers. As a foundational paper of a broader study investigating public and political influences on parents’ childcare choices, the paper details the use and utility of corpus linguistic tools for exploring the discourse construction of childcare in a large corpus of media texts. It also highlights the value of analysing media corpora via media ownership, focusing on the two dominant Australian media organisations, Fairfax and News Corp. Analyses reveal similarities but also key differences in the representation of childcare in Fairfax and News Corp newspapers. In Australia, print media still sets the daily media agenda and reflects the dominant discourse constructions surrounding major public issues. Accordingly, the beliefs, practices and decision-making of current and potential parent users of formal childcare may be differentially influenced depending not just on their (direct or indirect) access to print media, but by the format (tabloid or broadsheet) and thus ownership (Fairfax or News Corp).     

New media,new panics

ABSTRACT

When Stuart Hall and his Birmingham School colleagues argued that media technologies were essential to the production of moral panics, they focused on the relationship between mass media and the state. Because new technologies have altered our cultures of ostracism and punishment, we offer a revised analysis of this relationship that examines the role of online shaming in current moral panics. Not only do we analyze the new technological affordances of digital media, we argue that our current shaming culture is symptomatic of a deep-seated political disenfranchisement that leaves subjects grasping to “do something.” Contributing to a social media-driven panic culture that punishes and ostracizes deviants thus stands in for meaningful political participation. Ultimately, we argue that the evolving orientation to public life fostered by these new technologies has created a culture of shaming whereby citizens often prosecute their own discrete moral panics amid the more sustained sense of political crisis that characterizes contemporary life.     

Talent management in transnational higher education: strategies for managing academic staff at international branch campuses

The study investigates the practices of academic staff talent management at international branch campuses, with the aim of identifying a range of practical strategies that may address the unique challenges of managing talent in campuses located far away from the home country. These strategies are intended to improve service quality and add value to institution profiles. Based on an online questionnaire, ad hoc email correspondence and publicly available information, five case studies are presented. Talent management emerges as a key strategic area, directly managed at dean/president level. Referrals and online portals are commonly utilised as channels to attract talent, and the need to sometimes uplift local packages to recruit and retain talent is recognised. It is concluded that the development of academic staff should be viewed as an investment, and the availability of research funding and teaching awards on campus may be used to attract, develop and retain talent.
