Interestingness Measures for Multi-Level Association Rules

Association rule mining is one technique that is widely used when querying databases, especially those that are transactional, in order to obtain useful associations or correlations among sets of items. Much work has been done focusing on efficiency, effectiveness and redundancy. There has also been a focusing on the quality of rules from single level datasets with many interestingness measures proposed. However, with multi-level datasets now being common there is a lack of interestingness measures developed for multi-level and cross-level rules. Single level measures do not take into account the hierarchy found in a multi-level dataset. This leaves the Support-Confidence approach, which does not consider the hierarchy anyway and has other drawbacks, as one of the few measures available. In this chapter we propose two approaches which measure multi-level association rules to help evaluate their interestingness by considering the database’s underlying taxonomy. These measures of diversity and peculiarity can be used to help identify those rules from multi-level datasets that are potentially useful.

Critical discourse analysis

This chapter outlines the reasons why discourse analysis is an important dimension of critical social work practice. It brings to the forefront the very significant new contributions that sociologists focusing on the politics of recognition and redistribution, such as Nancy Fraser and Axel Honneth, can make in casting a "new politics of critical social work". In making this case, it begins by discussing some key developments in discourse theory and analysis within the social sciences and how they relate to the normative concerns of social work, specifically social justice and its multiple interpretations. Developing an appropriate analytical framework for social work practice can be difficult because there are conflicting and overlapping definitions of discourse formulated from various theoretical and disciplinary standpoints (Fairclough, 1992; Macdonnell, 1991). There are many different accounts of discourse that have developed in the social sciences, which is partly a result of recent interest in discourse theory among a wide range of academic disciplines. Whether language has assumed more of a central focus as a result of increased academic interest, or whether there has been an increase in the social importance of language in the operations of power is open to question...

Making mangoes move

A landscape of mangoes most likely brings to mind a place in a tropical location. By the end of the nineteenth century that place could have been located on any continent in the world. Mangoes were found in geographic locations; in scientific institutions; as crop plants; and as a backyard trees. Here I trace the movement of mangoes Mangifera indica Linn., focusing on the transnational links formed through colonial botanic gardens in Australia. Botanic gardens were largely understood through their work in establishing economically successful plantation crops, such as sugar and tea. Mangoes were not a success crop of the age of botanic imperialism. Instead, mangoes were simply one species among the millions of plants that botanic gardens moved in addition to these well known commercial crops. Colonial science moved plants for a myriad of other types of reasons, for ornament, for curiosity, for lesser commercial purposes and for pure science. In each site the mango emerged, the discourses and technologies that traveled with it changed according to local needs. Indeed, rather than finding mangoes located in one place, tracing their movement demonstrates that this was an extended landscape connecting these things across time and space...

Spatial Patterns of Malaria Reported Deaths in Yunnan Province, China

Malaria has been a heavy social and health burden in the remote and poor areas in southern China. Analyses of malaria epidemic patterns can uncover important features of malaria transmission. This study identified spatial clusters, seasonal patterns, and geographic variations of malaria deaths at a county level in Yunnan, China, during 1991–2010. A discrete Poisson model was used to identify purely spatial clusters of malaria deaths. Logistic regression analysis was performed to detect changes in geographic patterns. The results show that malaria mortality had declined in Yunnan over the study period and the most likely spatial clusters (relative risk [RR] = 23.03–32.06, P < 0.001) of malaria deaths were identified in western Yunnan along the China–Myanmar border. The highest risk of malaria deaths occurred in autumn (RR = 58.91, P < 0.001) and summer (RR = 31.91, P < 0.001). The results suggested that the geographic distribution of malaria deaths was significantly changed with longitude, which indicated there was decreased mortality of malaria in eastern areas over the last two decades, although there was no significant change in latitude during the same period. Public health interventions should target populations in western Yunnan along border areas, especially focusing on floating populations crossing international borders.

In vivo confocal microscopy of the ocular surface : from bench to bedside

In vivo confocal microscopy (IVCM) is an emerging technology that provides minimally invasive, high resolution, steady-state assessment of the ocular surface at the cellular level. Several challenges still remain but, at present, IVCM may be considered a promising technique for clinical diagnosis and management. This mini-review summarizes some key findings in IVCM of the ocular surface, focusing on recent and promising attempts to move “from bench to bedside”. IVCM allows prompt diagnosis, disease course follow-up, and management of potentially blinding atypical forms of infectious processes, such as acanthamoeba and fungal keratitis. This technology has improved our knowledge of corneal alterations and some of the processes that affect the visual outcome after lamellar keratoplasty and excimer keratorefractive surgery. In dry eye disease, IVCM has provided new information on the whole-ocular surface morphofunctional unit. It has also improved understanding of pathophysiologic mechanisms and helped in the assessment of prognosis and treatment. IVCM is particularly useful in the study of corneal nerves, enabling description of the morphology, density, and disease- or surgically induced alterations of nerves, particularly the subbasal nerve plexus. In glaucoma, IVCM constitutes an important aid to evaluate filtering blebs, to better understand the conjunctival wound healing process, and to assess corneal changes induced by topical antiglaucoma medications and their preservatives. IVCM has significantly enhanced our understanding of the ocular response to contact lens wear. It has provided new perspectives at a cellular level on a wide range of contact lens complications, revealing findings that were not previously possible to image in the living human eye. The final section of this mini-review provides a focus on advances in confocal microscopy imaging. These include 2D wide-field mapping, 3D reconstruction of the cornea and automated image analysis.

Business Innovation and Disruption in Publishing

This is the first volume in a book series examining how organizations in the creative industries respond to disruptive change and how they themselves generate business innovations. The aspiration of this book series is to understand some of the common forces behind the disruptions occurring in so many creative industries today and identifying the most promising strategies and responses by organizations to create new value propositions, business models and business practices that can enable these industry participants to cope with and eventually thrive as their industries and sectors are transformed. The chapters included in the volume examine the processes of disruption and transformation due to the technology of the Internet, social forces driven by social media, the development of new portable digital devices with greater capabilities and smaller size, the decreasing costs of new information, and the creation of new business models and forms of intellectual property ownership rights for a digitized industry. The context for this volume is the publishing industries, understood as the industries for the publishing of fiction and non-fiction books, academic literature, consumer as well as trade magazines, and daily newspapers. This volume includes chapters by an internationally diverse array of media scholars whose chapters provide insights into these phenomena in Eastern Europe, Finland, France, Germany, Norway, Portugal, Russia, and the United States, using different methodological frameworks including, but not limited to, surveys, in-depth interviews and multiple-case studies. One gap that this book series seeks to fill is that between the study of business innovation and disruption by innovation scholars largely based in business school settings and similar studies by scholarly experts from non-business school disciplines, including the broader social sciences (e.g. sociology, political science, economic geography) and creative industry based professional school disciplines (e.g. architecture, communications, design, film making, journalism, media studies, performing arts, photography and television). Future volumes of this book series will examine disruption and business innovation in the film, video and photography sectors (volume two), the music sector (volume three) and interactive entertainment (volume four), with subsequent volumes focusing on the most relevant developments in creative industry business innovation and disruption that emerge.

Cross-cultural web user interface design for Indigenous internet users

This project investigated 1) Australian web designers’ cultural perceptions towards Australian Indigenous users and 2) Australian Indigenous cultural features in terms of user interface design. In doing so, it reviews the literature of cross-cultural user interface design by focusing on feasible models and arguments to articulate and integrate Australian Indigenous Internet users’ cultural needs of web user interface. The online survey results collected from 101 Indigenous users and 126 Web designers showed a distinctive difference between them on the integration of Indigenous users' cultural in Web sites. The interview data collected from 14 Indigenous users and 14 web designers suggested practical approaches to the design implications of Indigenous culture.

Imprisoning rationalities

Imprisonment is a growth industry in Australia. Over the past 30–40 years all state and territory jurisdictions have registered massive rises in both the absolute numbers of those imprisoned and the per capita use of imprisonment as a tool of punishment and control. Yet over this period there has been surprisingly little criminological attention to the national picture of imprisonment in Australia and to understanding jurisdictional variation, change and continuity in broader theoretical terms. This article reports initial findings from the Australian Prisons Project, a multi-investigator Australian Research Council funded project intended to trace penal developments in Australia since about 1970. The article begins by outlining the notion of penal culture that provides the analytic lens for the project. It outlines various intersecting areas of study being undertaken before focusing on just three features of the contemporary penal field – restrictions upon presumptions of bail, the rise of post-sentence indefinite detention and the role of supermax confinement. Each in their own way exemplifies an aspect of and contributes to what we conclude to be the revalorization of the prison in Australian culture and society.

Examining fan attitudes toward sponsor brands using social identity frameworks

The majority of academic research has attempted to explain the effectiveness of sponsorship activities by focusing on individual outcomes (Cornwell, Weeks, & Roy, 2005). The current research builds upon the limited empirical studies that examine sponsorship outcomes using group behaviour theories (Cornwell & Coote, 2005; Gwinner & Swanson, 2003; Madrigal, 2000, 2001). Specifically, this study closely examines tenets of social identity theory (Brewer, 1991; Tajfel & Turner, 1979) within the context of sports sponsorship to test effects of team identification on attitudes toward associated sponsor brands. 1,840 unique surveys were collected from fans of the Queensland Maroons and New South Wales Blues rugby clubs over four timepoints during the 2012 State of Origin series. The results suggest that social identity effects were present regarding ingroup bias toward sponsor brands. Local sponsors were rated higher than non-local sponsors, suggesting that local brands may benefit more from sponsorship.

Identity orientation and stakeholder engagement—the corporatisation of elite schools

Identity orientation provides a means to understand the social motivations of organisational relationships and organisational policy and practices. This study uses identity orientation to understand the highly marketised context of independent ‘elite’ schools in Australia and how they relate to stakeholders to straddle their roles as social institutions that are increasingly required to operate in a corporate manner. Interviews with managers in quite new school roles such as marketing communication and business management were conducted in non-government schools to understand the schools' external orientations, coveted internal member traits, and frames of reference. The study shows that, in contrast to existing literature on the rhetoric of schools as focusing on ‘the child’, there was a strong emphasis on individualistic orientations in schools that saw stakeholders in instrumental terms of resources and connections, saw teachers as providing an innovative and leading edge, and used other prestigious schools as their frame of reference. To a lesser extent, schools would also be interested in the relationships with families, teachers, and the community for their own means. There were very few instances where the identity orientation was contributing to society, instead, focusing on university and network outcomes for pupils. Using identity orientation provides a theoretical lens to connect organisational governance to stakeholder engagement by providing insights into an organisation's identity including practices and behaviours, in relation to others.

Branding Melbourne : re-imagining the landscape through Christos Tsiolkas’ The Slap (2008)

In this paper I am focusing on one aspect of what Henri Lefebvre first termed the espace vecu “the fully lived space” (Soja 1999); and that aspect of space which exists within the geographical imagination. Building upon Lefebvre’s ideas Edward Soja acknowledges that “lived cities are never completely knowable” (1999) although in this paper I argue that often a fictional city is much more complex and diverse, much more revealing of the practices of everyday life than the homogenised concept often put forward in public discourses. Recent Melbourne fiction opens out this complexity, destabilizing public policy-making to reveal a socially diverse suburban landscape occupying both planned and organic spaces. The text that will be analysed in relation to this year’s conference theme The Geographical Imagination is a fictional text situated in Melbourne called The Slap that was written by Christos Tsiolkas in 2008.

Ruptured relations : guerrilla theatre, time & Pranksterish disability performance practice

Guerrilla theatre tends, by its very definition, to pop up unpredictably – it interrupts what people might see as the proper or typical flow of time, place and space. The subversive tenor of such work means that questions about ‘what has happened’ tend to the decidedly less polite form of ‘WTF’ as passersby struggle to make sense of, and move on from, moments in which accustomed narratives of action and interaction no longer apply. In this paper I examine examples of guerrilla theatre by performers with disabilities in terms of these ruptures in time, and the way they prompt reflection, reconfigure relations, or recede into traditional relations again - focusing particularly on comedian Laurence Clark. Many performers with disabilities – Bill Shannon, Katherine Araniello, Aaron Williamson, Ju Gosling, and others – find guerrilla-style interventions in public places apposite to their aesthetic and political agendas. They prompt passersby to reflect on their relationship to people with disabilities. They can be recorded for later dissection and display, teaching people something about the way social performers, social spectators and society as a whole deal with disability. In this paper, as I unpack Clark's work, I note that the embarrassment that characterises these encounters can be a flag of an ethical process taking place for passersby. Caught between two moments in which time, roles and relationships suddenly fail to flow along the smooth routes of socially determined habits, passersbys’ frowns, gasps and giggles flag difficulties dealing with questions about their attitude to disabled people they do not now know how to answer. I consider the productivity, politics and performerly ethics of drawing passersby into such a process – a chaotic, challenging interstitial time in which a passersbys choices become fodder for public consumption – in such a wholly public way.

Genuine community engagement in remote dryland regions : natural resource management in Lake Eyre Basin

Remote dryland regions are characterised by sparse populations and socially marginalised voices which pose particular challenges to natural resource management. This paper considers the issue of how to achieve community engagement in regions with these characteristics. In doing so, the paper contributes to an expanding international research agenda focusing on the distinct characteristics of arid and semi-arid regions under the heading of 'dryland syndrome'. The paper draws on government liaison officer and local community perspectives of successful engagement in the case-study region of Lake Eyre Basin, Australia. The results demonstrate that widely recognised characteristics of successful engagement are required but insufficient for genuine engagement in remote dryland regions. In addition to building trust through community ownership, being inclusive, effective communication, and adequate resources, genuine community engagement in drylands also requires respecting the extreme conditions and extraordinary variability of these areas. Residents of dryland regions seek genuine engagement yet engage opportunistically when seasons are conducive and when tangible outcomes are visible. © 2011 The Authors.

Exploring pedestrian accessibility and walkability : insight from public place observations in inner-urban higher density Brisbane, Australia

As planners work to create more sustainable and liveable urban environments, a priority is to transition away from prioritising the automobile and towards enhancing the pedestrian experience. Thus, this research explores the experience of pedestrian accessibility in inner-urban higher-density Brisbane in Australia, drawing on findings from semi-structured in-depth interviews with 24 residents and over 100 hours of public place observations in three case-study neighbourhoods. The interviews took place in residents homes and explored their experience of higher density living and their neighbourhood, whilst observations were recorded through a combination of methods including photographs, sketch maps, recordings and field journals. Observation locations included retail and commercial space, roads, parkland and open space, with multiple observations at each location. A thematic analysis identified common themes in both interviews and the observations, with this paper focusing on residents’ lived experience in urban built environments. This analysis revealed that pedestrian accessibility is linked to access to local amenities and direct routes, aesthetics, sense of community, ownership of space and safety. In particular, observations revealed how pedestrian accessibility and route-taking works with, against or in spite of the design features of urban environments, as well as the importance of the social use of the built environment. Residents spoke about although walking quick and preferred for local amenities, the decision to walk was moderated by factors such as time of day and perceived safety. Measures to ensure and improve the pedestrian accessibility of urban areas needs to take into account the propensity for people to prefer and improvise direct routes (often to the detriment of traffic safety considerations), the importance of ongoing maintenance and upgrading of walking infrastructure and the importance of aesthetically pleasing and safe walking environments. By combining interviews and observations, this research highlights the current dominance of the automobile culture in Brisbane and the layers of meaning, experiences and complexity hidden within the pedestrian experience.
