One tweet does not a revolution make : technological determinism, media and social change

This paper discusses the problematic influence of technological determinism in popular news media coverage and analysis of the Arab Spring events of 2010-11.

The purpose is to develop insights into how and why elements of a ‘soft’ technological determinism inflect both journalistic practice and news discourse in relation to the Arab Spring. In particular it discusses how the ‘bias of convenience’ and a journalistic obsession with the ‘continuous present’ connect with this determinist inflection to create a potential distortion in the journalists’ ‘first rough draft’ of history in relation to significant and complex events such as social revolution.

Tweet reach : a research protocol for using Twitter to increase information exchange in people with communication disabilities

Objective: To (a) outline the background to research evaluating Twitter use by people with severe physical and communication disabilities participating actively in online communication forums for increasing information exchange and (b) illustrate a range of potential methods that might be applied in furthering research on the use of social media by people with developmental and acquired communication disabilities. Methods: The literature on communication disabilities, augmentative and alternative communication, and social media research informed the rationale for and design of three studies investigating the use of Twitter by people with communication disabilities. Results: To date, there is little information in the literature about how people with a range of communication disabilities might use Twitter to increase their access to information and help them to feel knowledgeable and in control of their own lives. In this paper, three studies are proposed to investigate the use of Twitter by people with communication disabilities.

Two studies on Twitter networks and tweet content in relation to Amyotrophic Lateral Sclerosis (ALS): conversation, information, and ‘Diary of a Daily Life’

To date, there is no research examining how adults with Amyotrophic Lateral Sclerosis (ALS) or Motor Neurone Disease (MND) and severe communication disability use Twitter, nor the use of Twitter in relation to ALS/MND beyond its use for fundraising and raising awareness. In this paper we (a) outline a rationale for the use of Twitter as a method of communication and information exchange for adults with ALS/MND, (b) detail multiple qualitative and quantitative methods used to analyse Twitter networks and tweet content in the our studies, and (c) present the results of two studies designed to provide insights on the use of Twitter by an adult with ALS/MND and by #ALS and #MND hashtag communities in Twitter. We will also discuss findings across the studies, implications for health service providers in Twitter, and directions for future Twitter research in relation to ALS/MND.

More than just a transaction: conceptualising industry-based networks for virtual trading communities

This paper addresses the questions of why failure in industry-based networks has been so persistent and whether it is possible to avoid failure and achieve success in internet based markets [iMarketplaces]. A better explanation of implementation failures is important for both improved empirical outcomes and theory building. We construct a theoretical framework based on Bijker’s technology frame (1995) and a contextualization typology developed by Nowotny, Scott and Gibbons (2001). The framework helps us understand how industry-based networks function, why they fail and how we can apply the framework to assist better empirical outcomes. In this paper we apply our framework to Food Connect Australia, a vertically integrated marketplace, representative of the first wave of B2B markets. Sponsors of these iMarketplaces were quick to see and exploit the opportunities online access offered to bring together large numbers of buyers and sellers in new ways. However a lack of understanding of firstly, what represented true value in these networks and secondly, how to achieve buy-in at sustainable levels, meant that many of these first wave sites failed. Application of our framework reveals why there has been a radical shift from the trading role originally envisioned for these sites to the information hub model of the iMarketplace that industry is now being urged to adopt (Berryman and Heck, 2001).

Communication outside the humanities in media 'effect' research

This paper draws on the case study of a recent review of research literature on the influences (harms and benefits) on children and families of electronic media content and usage, undertaken on behalf of a Federal regulatory body (Australian Communications and Media Authority) by a multidisciplinary research team. Recent critiques of psychological studies of children and media have challenged the positivist social sciences to look outside of their own disciplinary warrants and to fully answer cultural studies critiques of ‘media effects’ research. Making connections outside the humanities in this case study involved making the rationales of communications and cultural studies methodologies available to those policy makers who normally may not consider such findings to be evidence-based or policy relevant. But it also involved providing a historical and institutional contextualization of positivist social and medical science findings, a contextualization not enabled by the underlying warrants and discourses of these disciplines. This paper focuses on those sections of the case study project concerned with psychological research on the effects of violent media and epidemiological and public health research on childhood obesity.

Recognizing and celebrating Xhosa traditional music in South Africa

The recognition and celebration of Indigenous Knowledge Systems (IKS) as a way forward to promote democracy and inclusivity continues to be part of South Africa's nation building process. One effective platform for this to take place is through community music making as music making in Africa is a way of life. Since democracy in 1994 many initiatives were set up to explore and foster traditional music. This paper presents a brief contextualization of IKS, identity and community music making. It reports on the a Xhosa music research project (2004-2006) as an ethnographic study which is descriptive and interpretive as a holistic cultural portrait. Participants in the project included post-graduate music students, community culture bearers and academics. Only some significant aspects of the Xhose music project at the University of Fort Hare will be reported on. We contextualize the recognition and celebration of IKS within the parameters of the music and the culture of the amaMpondo within the Xhosa people. The paper specifically focuses on the ritual life of the amaMpondo. It also describes the indigenous bow instruments of the Uhadi and Umrhubhe as unique examples of South Africa's traditional music. As this initiative proved a worthy undertaking, we challenge whether such a project could strengthen local IKS elsewhere and be a pathway for tertiary institutions to engage effectively with local community music practitioners in order to prepare students effectively as holistic music educators.

Researching women in silent cinema: new findings and perspectives

This anthology exposes the richness and variety of interests that motivate feminist film research today. Exploring women’s contribution to silent cinema, scholars from across the globe address questions of performance, nationality, industry, technology, labor, and theory of feminist historiography. The volume builds on the thematic, methodological, and material diversity that characterized earlier efforts in women’s film history, and the originating context of the sixth Women and the Silent Screen conference (Bologna, 2010). Much emphasis is given to the transitional period of silent cinema (1910s to the early 1920s), which emerges as the field where feminist film scholars are beginning to claim their own theoretical and historical ‘place’. While giving a new impetus to the idea of transitional cinema, the collected essays also illuminate the importance of film’s transnational circulation. Questions of nation and nationhood, and women’s inclusion or exclusion within these terms, are examined in connection to issues of cultural globalization. How did American serial queens impact early Chinese film? How did the variety stage accommodate American films in Rio de Janeiro? Along what lines might we discuss women filmmakers who literally toured the world? These are just some of the issues that are discussed in the volume. Each investigation prompts us into distinct acts of cultural contextualization. A particular focus on acting and the agency of the actress is shared across the volume. The fundamental figure of the actress links multiple threads of scholarship, traversing different films and national cinemas. Alice Guy, Asta Nielsen, Florence Turner, Lois Weber, Mary Pickford, Esfir’ Shub, Pearl White, Vera Karalli, Aleksandra Khokhlova, Elsa Lanchester, Louise Fazenda, Sarah Bernhardt, Gemma Bellincioni, Angelina Buracci, Yin Mingzhu, Leni Riefensthal: these are but some of the names that are encountered across the essays in the collection. New findings are exposed and new research perspectives are opened through these and other figures, allowing us to uncover original ways of thinking about women’s visibility and agency on film.

Exploring distributed leadership in the small business context

Entrepreneurial ventures are often established, controlled and led through the commitment of individuals. This article problematizes the nature of the form of leadership relevant for the small business as it matures. In this way, it explores the temporal dimension to the appropriateness of distributed leadership in the context of the entrepreneurial business. The authors critique the opportunity that distributed leadership can bring to the maturing business. They illuminate a dilemma for entrepreneurs as to whether they should give up control for a broader distributed process of leading or continue a practice of leading that resonates with their essence of being entrepreneurial - independent, controlling responsive and opportunity driven. This dilemma is addressed by suggesting the contextualization of distributed leadership may offer the maturing business. The article concludes by reviewing development approaches that contextualize intervention and suggests a research agenda to contribute to a greater understanding of how leadership can become distributed in the maturing business. © 2011 The Authors.

Characterizing university library use of social media: a case study of twitter and facebook from Australia

The work presented here characterise the engagement of one university library with two social media platforms popular with academic libraries. The collected data are analysed to identify the forms of Twitter and Facebook activity that engage library stakeholders in social media conversations. Associations were observed between: i) directed tweets from the library and mentions of the library by others on Twitter; and ii) comments from the library and comments from others on Facebook. Three broad classes of Twitter user interacting with the library were revealed: i) accounts strongly linked to the library with multiple to/from tweets; ii) those weakly linked to the library with, typically, a single tweet; and iii) those indirectly linked to the library through tweets mentioning the library and sent by other users. Two divergent forms of Facebook interaction with the library were highlighted: i) a library post generating a large sequence of comments, typically in response to a competition/challenge and ii) a library post with no comments, typically a photo post or a post inviting readers to click a link to find out more about an event/service. The work presented here is an initial investigation that provides useful insights, and offers a methodology for future research.

Overcoming data scarcity of Twitter: using tweets as bootstrap with application to autism-related topic content analysis

Notwithstanding recent work which has demonstrated the potential of using Twitter messages for content-specific data mining and analysis, the depth of such analysis is inherently limited by the scarcity of data imposed by the 140 character tweet limit. In this paper we describe a novel approach for targeted knowledge exploration which uses tweet content analysis as a preliminary step. This step is used to bootstrap more sophisticated data collection from directly related but much richer content sources. In particular we demonstrate that valuable information can be collected by following URLs included in tweets. We automatically extract content from the corresponding web pages and treating each web page as a document linked to the original tweet show how a temporal topic model based on a hierarchical Dirichlet process can be used to track the evolution of a complex topic structure of a Twitter community. Using autism-related tweets we demonstrate that our method is capable of capturing a much more meaningful picture of information exchange than user-chosen hashtags.

Clinical placement before or after simulated learning environments? A naturalistic study of clinical skills acquisition among early-stage paramedicine students

BACKGROUND: There is conflicting evidence surrounding the merit of clinical placements (CPs) for early-stage health-profession students. Some contend that early-stage CPs facilitate contextualization of a subsequently learned theory. Others argue that training in simulated-learning experiences (SLEs) should occur before CP to ensure that students possess at least basic competency. We sought to investigate both claims. METHODS: First-year paramedicine students (n = 85) undertook 3 days of CP and SLEs as part of course requirements. Students undertook CP either before or after participation in SLEs creating 2 groups (Clin → Sim/Sim → Clin). Clinical skills acquisition was measured via direct scenario-based clinical assessments with expert observers conducted at 4 intervals during the semester. Perceptions of difficulty of CP and SLE were measured via the National Aeronautics and Space Administration Task Load Index. RESULTS: Students' clinical assessment scores in both groups improved significantly from beginning to end of semester (P < 0.001). However, at semester's end, clinical assessment scores for the Sim → Clin group were statistically significantly greater than those of the Clin → Sim group (P = 0.021). Both groups found SLEs more demanding than CP (P < 0.001). However, compared with the Sim → Clin group, the Clin → Sim group rated SLE as substantially more time-demanding than CP (P = 0.003). CONCLUSIONS: Differences in temporal demand suggest that the Clin → Sim students had fewer opportunities to practice clinical skills during CP than the Sim → Clin students due to a more limited scope of practice. The Sim → Clin students contextualized SLE within subsequent CP resulting in greater improvement in clinical competency by semester's end in comparison with the Clin → Sim students who were forced to contextualize skills retrospectively.

Splitting centre : directing attention in trans-media dance performance

In theatrical vernacular, the term ‘splitting centre’ refers to two performers staged at an equal distance from a centre point and sharing the focus of the audience. This term encapsulates the notion that two people (or, in the case of trans-media dance, two or more performance entities) are dividing the attention of the audience, operating as equal collaborators in a performance context. The augmentation of live performance with 3D projected scenography and mobile devices offers a starting point for discussions on the potential for dramaturgy, choreographic process, and changing expectations for audience behaviour in the theatre. In 2014, Deakin Motion.Lab premiered The Crack Up, a trans-media dance work that incorporated live performance, 3D digital scenography, and The Crack Up App, an app for mobile devices that audience members were invited to interact with during the performance. This investigation into the potential of trans-media dance performance, (defined here as a live performance in which both the digital and biological elements are choreographed as artistic equals within the theatrical context) with the addition of a mobile device raises questions about how the makers of trans-media dance might direct the attention of their audiences when the work is performed simultaneously across multiple platforms.

A performance evaluation of machine learning-based streaming spam tweets detection

The popularity of Twitter attracts more and more spammers. Spammers send unwanted tweets to Twitter users to promote websites or services, which are harmful to normal users. In order to stop spammers, researchers have proposed a number of mechanisms. The focus of recent works is on the application of machine learning techniques into Twitter spam detection. However, tweets are retrieved in a streaming way, and Twitter provides the Streaming API for developers and researchers to access public tweets in real time. There lacks a performance evaluation of existing machine learning-based streaming spam detection methods. In this paper, we bridged the gap by carrying out a performance evaluation, which was from three different aspects of data, feature, and model. A big ground-truth of over 600 million public tweets was created by using a commercial URL-based security tool. For real-time spam detection, we further extracted 12 lightweight features for tweet representation. Spam detection was then transformed to a binary classification problem in the feature space and can be solved by conventional machine learning algorithms. We evaluated the impact of different factors to the spam detection performance, which included spam to nonspam ratio, feature discretization, training data size, data sampling, time-related data, and machine learning algorithms. The results show the streaming spam tweet detection is still a big challenge and a robust detection technique should take into account the three aspects of data, feature, and model.
