Escaping the Trap of too Precise Topic Queries

At the very center of digital mathematics libraries lie controlled vocabularies which qualify the {\it topic} of the documents. These topics are used when submitting a document to a digital mathematics library and to perform searches in a library. The latter are refined by the use of these topics as they allow a precise classification of the mathematics area this document addresses. However, there is a major risk that users employ too precise topics to specify their queries: they may be employing a topic that is only "close-by" but missing to match the right resource. We call this the {\it topic trap}. Indeed, since 2009, this issue has appeared frequently on the i2geo.net platform. Other mathematics portals experience the same phenomenon. An approach to solve this issue is to introduce tolerance in the way queries are understood by the user. In particular, the approach of including fuzzy matches but this introduces noise which may prevent the user of understanding the function of the search engine. In this paper, we propose a way to escape the topic trap by employing the navigation between related topics and the count of search results for each topic. This supports the user in that search for close-by topics is a click away from a previous search. This approach was realized with the i2geo search engine and is described in detail where the relation of being {\it related} is computed by employing textual analysis of the definitions of the concepts fetched from the Wikipedia encyclopedia.Comment: 12 pages, Conference on Intelligent Computer Mathematics 2013 Bath, U

A Survey on Retrieval of Mathematical Knowledge

We present a short survey of the literature on indexing and retrieval of mathematical knowledge, with pointers to 72 papers and tentative taxonomies of both retrieval problems and recurring techniques.Comment: CICM 2015, 20 page

Search Interfaces for Mathematicians

Access to mathematical knowledge has changed dramatically in recent years, therefore changing mathematical search practices. Our aim with this study is to scrutinize professional mathematicians' search behavior. With this understanding we want to be able to reason why mathematicians use which tool for what search problem in what phase of the search process. To gain these insights we conducted 24 repertory grid interviews with mathematically inclined people (ranging from senior professional mathematicians to non-mathematicians). From the interview data we elicited patterns for the user group "mathematicians" that can be applied when understanding design issues or creating new designs for mathematical search interfaces.Comment: conference article "CICM'14: International Conference on Computer Mathematics 2014", DML-Track: Digital Math Libraries 17 page

Critical Practice

This book is available as open access through the Bloomsbury Open Access programme and is available on www.bloomsburycollections.com. What is the relationship between theory and practice in the creative arts today? In Critical Practice, Martin McQuillan offers a critical interrogation of the idea of practice-led research. He goes beyond the recent vocabulary of research management to consider the more interesting question of the emergence of a cultural space in which philosophy, theory, history and practice are becoming indistinguishable. McQuillan considers the work of a number of writers and thinkers who cross the divide between theoretical and creative practice, including Alain Badiou and Terry Eagleton, and the longer tradition of 'theory-writing' that runs through the work of Hélène Cixous, Roland Barthes and Louis Althusser. His aim is to elucidate the contemporary ramifications of a relationship that has been contested throughout the long history of philosophy, from Plato's dialogues to Derrida's 'Envois'

No signal here: self-development and optimal experience from digital-free tourism

The present research aims to establish a conceptual understanding of the benefits tourists may gain from digital-free tourism. The concept of digital-free tourism was proposed to represent situations characterised by the absence of or severely limited access to information and communication technology. There has been a contemporary concern over the sustained use of the internet and digital technologies, in terms of the side-effects on individuals' physical, psychological and social conditions and the possible deterioration of tourist experience. Therefore, the assumption of the potential of reduced technology use in tourism to improve tourist well-being has been claimed. Four interrelated studies were conducted to investigate the topic both as a social phenomenon and a niche tourism market. The rewarding outcomes of digital-free tourism were examined by addressing three specific questions. The first research question "is digital-free tourism rising in prominence?" was answered by the first study – media representation of digital-free tourism: a critical discourse analysis included in Chapter 2 of this thesis. Archival data, that is online media documents focusing on the broad topic of digital detoxing on holiday, was analysed at three levels, including linguistic characteristics, temporal diachronic interpretation and socio-cultural explanation. Media discourses around digital-free tourism were found to be evolving. Specifically, vacations and tourism are discoursed as ideal situations for managing technology use behaviours. The value of digital-free tourism over time has moved from relieving stress to life flourishing. Multiple digital-free tourism providers now offer diverse experiences to a growing broad market. The second research question "what are the positive experiences and impacts of digital-free tourism?" was answered by conducting the second study – exploration of benefits from digital-free tourism: a grounded theory approach in Chapter 3. Sixty five carefully selected key informants with expert knowledge or personal experience of digital-free tourism were asked to report their experience, observations and perspectives about reduced technology use on holiday. Based on the patterns in the data, a theoretical model was developed to display the positive changes of tourists' psychological, behavioural and life conditions through the process of digital-free tourism. The third research question "in what ways does digital-free vacation experience contribute to people's well-being?" was addressed in two further in-depth studies. These studies were developed in Chapters 4 and 5. The third study in Chapter 4 - self-development in digital-free tourism: building character strengths through coping with challenging investigated the correlations between digital-free tourism and the development of character strengths and virtues which build personal well-being. Key-informants' statements obtained in the previous study were re-coded by employing a catalogue of twenty four character strengths in positive psychology as a priori coding scheme. In the results, twenty three character strengths were found to be related to digital-free tourism. They were perceived to be the strengths that were utilised to cope with issues faced in the digital-free contexts. A tiered model was built to outline the core, secondary and peripheral strengths in digital-free tourism. The fourth study in Chapter 5 - optimal experience: the role of reduced smartphone use in increasing perception of restorative environments and producing flow attempted to develop measures for the levels of perceived restorative quality of digital-free tourism environments and the flow tourists experienced when technology use was reduced; as well as to examine the nexus among critical variables by testing a Partial Least Squares Structural Equation Model (PLS-SEM). The hypothesised positive correlation between restorative environment and flow was confirmed. Smartphone dependence was found to be effective in reducing the level of flow and moderating the relationship between restorative environment and flow. A VI trend of high dependence on smartphone weakening tourists' ability to perceive restorative digital-free environment was also revealed by this empirical study. Consequently, the value and significance of positive changes of tourists' psychological, social, behavioural and life conditions arising from disconnection are suggested in these findings about the understudied concept of digital-free tourism. Such knowledge can make important theoretical contributions to the understanding of the intricate relationship between technology and tourism, the rewarding outcomes of vacation time involving reduced technology engagement, and the well-being from positive tourist experience. Digital-free tourism can provide individuals opportunities to experience a new way of being in this digital era, reflect on and regulate the technology use behaviours of themselves and their families, as well as increase well-being through selecting unplugging vacations. The present research also introduced digital-free tourism as a new style of tourism product and service that can be an effective strategy for remote regions to develop innovative forms of tourism

Google-induced confidence in decision skills changes experiences : a self-fulfilling prophecy

The Internet is the ultimate memory entity, storing unimaginable amounts of information and capable of retrieving target pieces in less than a second. Thanks to tools like Google, resorting to this entity when trying to remember or learn facts has become as natural for people as eating when feeling hungry. Recent evidence suggests that embracing the Internet as a memory resource deregulates metacognition because people conflate knowledge accessed online with their own. The current research shows that this conflation entails a “feeling of already knowing” that, in consumer contexts, leads to overconfidence in decision skills. Most importantly, and contrasting with the common view of overconfidence as a trap, this research proposes that, albeit illusory, Google-induced choice confidence (the belief that the chosen option is superior to the dismissed ones) gives rise to affective expectations that spill over into subjective experiences. In essence, the Internet entails a self-fulfilling prophecy where it misguides people into believing that they made an objectively optimal decision but also leads them to have subjectively better experiences as the outcome of that decision
