Creating and sharing : teens' information practices in digital communities

Introduction In a connected world youth are participating in digital content creating communities. This paper introduces a description of teens' information practices in digital content creating and sharing communities. Method The research design was a constructivist grounded theory methodology. Seventeen interviews with eleven teens were collected and observation of their digital communities occurred over a two-year period. Analysis The data were analysed iteratively to describe teens' interactions with information through open and then focused coding. Emergent categories were shared with participants to confirm conceptual categories. Focused coding provided connections between conceptual categories resulting in the theory, which was also shared with participants for feedback. Results The paper posits a substantive theory of teens' information practices as they create and share content. It highlights that teens engage in the information actions of accessing, evaluating, and using information. They experienced information in five ways: participation, information, collaboration, process, and artefact. The intersection of enacting information actions and experiences of information resulted in five information practices: learning community, negotiating aesthetic, negotiating control, negotiating capacity, and representing knowledge. Conclusion This study contributes to our understanding of youth information actions, experiences, and practices. Further research into these communities might indicate what information practices are foundational to digital communities.

The role of Non-Government Organisations (NGOS) in practising editorial photography in a globalised media environment

The news media industry has changed dramatically into a global business with ever-increasing attention being devoted to entertainment and celebrity across the last 10–20 years. There has also been a growing reliance on images produced by citizens (citizen photojournalism), by media outlets and publishers. It is widely acknowledged that in tandem these changes have shrunk publication opportunities for professional photographers undertaking editorial projects. As a result, photographers are increasingly relying on non-government organisations (NGOs) to gain access to photographing issues and events in developing countries and to expand their economic and portfolio opportunities. This increase in photographers working for and alongside NGOs has given rise to a new genre of editorial photography which I call NGO Reportage. By way of a case study, an exploration of this new genre reveals important issues for photographers working with NGOs and examines the constructed narratives of images contained within these emerging practices.

Unconditionally secure disjointness tests for private datasets

We present two unconditional secure protocols for private set disjointness tests. In order to provide intuition of our protocols, we give a naive example that applies Sylvester matrices. Unfortunately, this simple construction is insecure as it reveals information about the intersection cardinality. More specifically, it discloses its lower bound. By using the Lagrange interpolation, we provide a protocol for the honest-but-curious case without revealing any additional information. Finally, we describe a protocol that is secure against malicious adversaries. In this protocol, a verification test is applied to detect misbehaving participants. Both protocols require O(1) rounds of communication. Our protocols are more efficient than the previous protocols in terms of communication and computation overhead. Unlike previous protocols whose security relies on computational assumptions, our protocols provide information theoretic security. To our knowledge, our protocols are the first ones that have been designed without a generic secure function evaluation. More important, they are the most efficient protocols for private disjointness tests in the malicious adversary case.

Feminist crime fiction : an examination of embodied feminist intentions in Denise Mina’s The Field of Blood (2005)

The writing of award winning tartan noir author, Denise Mina, “crime queen of Glasgow” has been identified with “explicitly feminist politics,” and Mina herself claims, as a feminist, she wants to use crime fiction to present a “narrative about very disempowered people becoming empowered.” This paper explores how Mina’s avowed stance on feminism plays out in her novel, The Field of Blood (2005), and examines whether her concerns are reflected in the embodied actions of her young protagonist, would-be investigative journalist, Paddy Meehan. It asks whether Mina has succeeded in working against entrenched patriarchal codes of crime fiction’s dominant narrative construction or whether her feminist intentions have been undermined by traditional stereotypical conventions of the genre.

Telling bodies, mapping knowledge : recontextualising the dancer’s corporeality using a modular choreographic model

Creative Development: The Body and Light. Within the current cultural climate, the independent choreographer struggles to pursue and establish their artistic career outside the infrastructure of mainstream dance companies. The independent choreographer is challenged to articulate alternative choreographic models without the support of that infrastructure. My research examines that challenge by exploring my own independent choreographic practice through a number of performance-based dance projects. This exploration will be underpinned by theoretical research to enable clarification of the tacit understandings of an embodied practice and the point of intersection between practice and theory so as to articulate alternative choreographic models. As a starting point for that enquiry, an example is provided of how questions that emerge from within the choreographic practice can be discussed in terms of research through an initial investigation exploring light in relation to the moving body and the implications of atmospheres.

An analysis for the causes of accidents of repair, maintenance, alteration and addition works in Hong Kong

This study unveils causes of accidents in repair, maintenance, alteration and addition (RMAA) work. RMAA work is playing an increasingly important role in developed societies, including Hong Kong. Safety problems associated with RMAA work in Hong Kong has reached an alarming level. In view of rapid expansion of the RMAA sector and rising proportion of accidents in the construction industry, there is a pressing need to investigate causes of RMAA accidents. Structured interviews were conducted with RMAA contractors to explore causes of accidents in the RMAA sector. A two-round Delphi method with 13 safety experts was subsequently employed to verify the interview findings and rank the relative degree of importance for various causes of accidents. Accidents happen in RMAA work due to intersection of reasons. One of the root causes of accidents in RMAA works is low safety awareness of RMAA workers; however, wider organizational and industrial factors are not negligible. This study sheds light on why accidents happen in the RMAA sector. Only when the factors leading to accidents are identified can effective measures be made.

Lying in all honesty : capturing truth in women’s confessional memoir

This paper explores the slippery nature of illness and diagnosis in Lauren Slater’s memoir, Lying: a Metaphorical Memoir (2000). Speaking from the shadowy intersection of childhood and adolescence, Slater’s narrator, Lauren, uses the metaphor of epilepsy to describe her own predilection for exaggeration. In exploiting the fallibility of the first-person narrator, Slater insists on the legitimacy of metaphor in accounts of childhood illness that are more concerned with narrative truth than historical accuracy. The result of this playfulness and general misrule is that Slater writes herself into a double bind: on one side, she is the child narrator who inadvertently misrepresents events and misdirects readers, and on the other side, she is the untrustworthy author who employs metaphor as a licence to lie.

Pulping affirmation : Danny Wallace’s Yes Man!

If Danny Wallace is a yes man, I am most certainly a no woman. No, I will not agree to anything and everything in an attempt to make my life “more interesting”. No, I do not believe that on “one fateful day a mystery man on a late night bus” will change my life forever. I hate the bus. In fact, I don’t even catch public transport. Wallace’s recent film tie-in Yes Man reeks of such cheesy optimism. The book’s premise is simple and indeed, even alluring at first. When a stranger on the bus tells Danny to “say yes more” (9), his life takes a dramatic turn on the roundabout of possibility. Sad, single, and staying inside a lot, Danny signs himself up for a year of mishap and misadventure, accepting every request, suggestion and invitation offered to him by both friends and strangers.

Australian Indigenous Art : Local Dreamings, Global Consumption (Autohtona Australijska Umetnost : Lokalno Sanjarenje, Globalna Potražnja)

Indigenous Australian visual art is an outstanding case of the dynamics of globalization and its intersection with the hyper-local wellsprings of cultural expression, and of the strengths and weaknesses of state, philanthropic and commercial backing for cultural production and dissemination. The chapter traces the development of the international profile of Indigenous ‘dot’ art – a traditional symbolic art form from the Western Desert – as ‘high-end’ visual art, and its positioning within elite markets and finance supported by key international brokers, collectors and philanthropists.

Efficient disjointness tests for private datasets

We present efficient protocols for private set disjointness tests. We start from an intuition of our protocols that applies Sylvester matrices. Unfortunately, this simple construction is insecure as it reveals information about the cardinality of the intersection. More specifically, it discloses its lower bound. By using the Lagrange interpolation we provide a protocol for the honest-but-curious case without revealing any additional information. Finally, we describe a protocol that is secure against malicious adversaries. The protocol applies a verification test to detect misbehaving participants. Both protocols require O(1) rounds of communication. Our protocols are more efficient than the previous protocols in terms of communication and computation overhead. Unlike previous protocols whose security relies on computational assumptions, our protocols provide information theoretic security. To our knowledge, our protocols are first ones that have been designed without a generic secure function evaluation. More importantly, they are the most efficient protocols for private disjointness tests for the malicious adversary case.

Distributed private matching and set operations

Motivated by the need of private set operations in a distributed environment, we extend the two-party private matching problem proposed by Freedman, Nissim and Pinkas (FNP) at Eurocrypt’04 to the distributed setting. By using a secret sharing scheme, we provide a distributed solution of the FNP private matching called the distributed private matching. In our distributed private matching scheme, we use a polynomial to represent one party’s dataset as in FNP and then distribute the polynomial to multiple servers. We extend our solution to the distributed set intersection and the cardinality of the intersection, and further we show how to apply the distributed private matching in order to compute distributed subset relation. Our work extends the primitives of private matching and set intersection by Freedman et al. Our distributed construction might be of great value when the dataset is outsourced and its privacy is the main concern. In such cases, our distributed solutions keep the utility of those set operations while the dataset privacy is not compromised. Comparing with previous works, we achieve a more efficient solution in terms of computation. All protocols constructed in this paper are provably secure against a semi-honest adversary under the Decisional Diffie-Hellman assumption.

Irregular readers : Arthur Conan Doyle’s “six dirty scoundrels”, boyhood and literacy in contemporary Sherlockian children’s literature

Young adult (YA) literature is a socialising genre that encourages young readers to take up particular ways of relating to historical or cultural materials. The first decade of the twenty-first century witnessed a boom in Sherlockian YA fiction using the Conan Doyle canon as a context and vocabulary for stories focused on the Baker Street Irregulars as figures of identification. This paper reads YA fiction’s deployment of Conan Doyle’s fictional universe as a strategy for negotiating anxieties of adolescent masculinity, particularly in relation to literacy and social agency.

Cork as canvas : exploring intersections of citizenship and collective memory in the Shandon Big Wash Up murals

Urban space has the potential to shape people's experience and understanding of the city and of the culture of a place. In some respects, murals and allied forms of wall art occupy the intersection of street art and public art; engaging, and sometimes, transforming the urban space in which they exist and those who use it. While murals are often conceived as a more ‘permanent’ form of painted art there has been a trend in recent years towards more deliberately transient forms of wall art such as washed-wall murals and reverse graffiti. These varying forms of public wall art are embedded within the fabric of the urban space and history. This paper will explore the intersection of public space, public art and public memory in a mural project in the Irish city of Cork. Focussing on the washed-wall murals of Cork's historic Shandon district, we explore the sympathetic and synergetic relationship of this wall art with the heritage architecture of the built environment and of the murals as an expression of and for the local community, past and present. Through the Shandon Big Wash Up murals we reflect on the function of participatory public art as an explicit act of urban citizenship which works to support community-led re-enchantment in the city through a reconnection with its past.

Fashion meets journalism : mapping and evaluating Australian fashion journalism

Fashion journalism can be understood as a complex, inter-dependent set of professional practices that have arisen in a variety of media at the intersection of fashion and journalism. This thesis, Fashion Meets Journalism: Mapping and Evaluating Australian Fashion Journalism, answers the question, 'What is Australian fashion journalism?' in three stages: First, it maps the extent of fashion journalism across media in Australia to locate the field and focus on the sites of fashion journalism; second, it foregrounds practices of the journalism branch, evaluating how and why the field is pitted against other types of journalism when they share an inter-dependent set of professional practices. The opinions of leading industry producers are also sought regarding the matter. Then, considering the current position of fashion journalism, implications for fashion media and journalism are explored in order to improve the visibility of fashion journalism and solidify it as a professional practice.
