The decision in Hook v Boreham & QBE Insurance (Australia) Limited [2006] QDC 304 considered whether the court should go further than order that costs be assessed on the indemnity basis, but should also specify the basis by which those indemnity costs should be determined. The decision makes it clear that under r704(3) of the Uniform Civil Procedure Rules, questions of that nature are ordinarily preserved to the discretion of the Registrar.

Digital signature is a breakthrough of modern cryptographic systems. A (t, n) threshold digital signature allows every set of cardinality t or more (out-of n) co-signers to authenticate a message. In almost all existing threshold digital signatures the threshold parameter t is fixed. There are applications, however, in which the threshold parameter needs to be changed from time to time. This paper considers such a scenario, in order to discuss relevant problems, and proposes a model that solves the related problems.

Multi-party key agreement protocols indirectly assume that each principal equally contributes to the final form of the key. In this paper we consider three malleability attacks on multi-party key agreement protocols. The first attack, called strong key control allows a dishonest principal (or a group of principals) to fix the key to a pre-set value. The second attack is weak key control in which the key is still random, but the set from which the key is drawn is much smaller than expected. The third attack is named selective key control in which a dishonest principal (or a group of dishonest principals) is able to remove a contribution of honest principals to the group key. The paper discusses the above three attacks on several key agreement protocols, including DH (Diffie-Hellman), BD (Burmester-Desmedt) and JV (Just-Vaudenay). We show that dishonest principals in all three protocols can weakly control the key, and the only protocol which does not allow for strong key control is the DH protocol. The BD and JV protocols permit to modify the group key by any pair of neighboring principals. This modification remains undetected by honest principals.

We study the natural problem of secure n-party computation (in the passive, computationally unbounded attack model) of the n-product function f G (x 1,...,x n ) = x 1 ·x 2 ⋯ x n in an arbitrary finite group (G,·), where the input of party P i is x i  ∈ G for i = 1,...,n. For flexibility, we are interested in protocols for f G which require only black-box access to the group G (i.e. the only computations performed by players in the protocol are a group operation, a group inverse, or sampling a uniformly random group element). Our results are as follows. First, on the negative side, we show that if (G,·) is non-abelian and n ≥ 4, then no ⌈n/2⌉-private protocol for computing f G exists. Second, on the positive side, we initiate an approach for construction of black-box protocols for f G based on k-of-k threshold secret sharing schemes, which are efficiently implementable over any black-box group G. We reduce the problem of constructing such protocols to a combinatorial colouring problem in planar graphs. We then give two constructions for such graph colourings. Our first colouring construction gives a protocol with optimal collusion resistance t < n/2, but has exponential communication complexity O(n*2t+1^2/t) group elements (this construction easily extends to general adversary structures). Our second probabilistic colouring construction gives a protocol with (close to optimal) collusion resistance t < n/μ for a graph-related constant μ ≤ 2.948, and has efficient communication complexity O(n*t^2) group elements. Furthermore, we believe that our results can be improved by further study of the associated combinatorial problems.

The emergence of the Internet is one of the most significant leaps in the history of humanity. Information, knowledge and culture are exchanged among masses of people through interconnected information platforms. These platforms enable our culture to be analysed and rewritten, and fundamentally opens our perceptions to a wide variety of concepts and beliefs. The connected networks of the Internet have shaped a virtual — but communicative — space where people can cross borders freely within a realm characterised by the ability to go anywhere, see anything, learn, compare and understand. This chapter focuses on the Libyan experience with social networking platforms in actualising democratic change in the uprising of 17 February 2011. After briefly outlining the political and economic situation under the regime of Colonel Mummar Ghaddafi, the chapter discusses the role that social networking platforms played during the struggle of the Libyan people for democratic change. Finally, it points out the positive changes that resulted from the uprising and the potential role that social media might play in the ongoing democratization and development of Libyan society.

The debate about the democratic significance of these trends—a more aggressively inquisitorial media environment, greater public participation in political communication, a more accessible and transparent (at least in appearance) political class—continues, not least in Australia. This essay was written in the first half of 2013, a time of extreme political volatility in Australia, and in the run-up to a general election following three years of minority Labor government. By that stage in the political cycle, Prime Minister Julia Gillard had survived not one but two attempts at leadership “spills”, ministers had resigned or been sacked for disloyalty to the leader, major policy initiatives had been dumped, reversed or quietly dropped, and a Coalition opposition was confidently looking forward to a landslide majority in the election of September that year. Labor’s internal party turmoil, rather than the Coalition’s policy prospectus (which remained sketchy and vague right up to the eve of the election), were widely assumed to be the cause of the former’s poor standing in the opinion polls.

YouTube is contemplating the launch of a new music service. But how would such a service fare against established music services like Spotify, Rdio, and Pandora? All these services are referred to as “access-based music services”. They offer music listeners access to millions of songs they can listen to as much as they want for free (with advertising and only basic functionality) or for a monthly subscription fee (without advertising)...

This paper offers a definition of elite media arguing their content focus will sufficiently meet social responsibility needs of democracy. Its assumptions come from the Finkelstein and Leveson Inquiries and regulatory British Royal Charter (2013). These provide guidelines on how media outlets meet ‘social responsibility’ standards, e.g. press has a ‘responsibility to be fair and accurate’ (Finkelstein); ethical press will feel a responsibility to ‘hold power to account’ (Leveson); news media ‘will be held strictly accountable’ (RC). The paper invokes the British principle of media opting-in to observe standards, and so serve the democracy. It will give examples from existing media, and consider social responsibility of media more generally. Obvious cases of ‘quality’ media: public broadcasters, e.g. BBC, Al-Jazeera, and ‘quality’ press, e.g. NYT, Süddeutscher Zeitung, but also community broadcasters, specialised magazines, news agencies, distinctive web logs, and others. Where providing commentary, these abjure gratuitous opinion -- meeting a standard of reasoned, informational and fair. Funding is almost a definer, many such services supported by the state, private trusts, public institutions or volunteering by staff. Literature supporting discussion on elite media will include their identity as primarily committed to a public good, e.g. the ‘Public Value Test’, Moe and Donders (2011); with reference also to recent literature on developing public service media. Within its limits the paper will treat social media as participants among all media, including elite, and as a parallel dimension of mass communication founded on inter-activity. Elite media will fulfil the need for social responsibility, firstly by providing one space, a ‘plenary’ for debate. Second is the notion of building public recognition of elite media as trustworthy. Third is the fact that elite media together are a large sector with resources to sustain social cohesion and debate; notwithstanding pressure on funds, and impacts of digital transformation undermining employment in media more than in most industries.

A 3hr large scale participatory installation/event that included live performance, video works,objects, fabric sculptures and was the result of a three month artist residency undertaken by Cam Lab (Jemima Wyman and Anna Mayer)at the Museum of Contemporary Art Los Angeles California. The exhibition transformed two adjoining spaces in the museum, taking design cues from permanent collection artworks currently on view and encouraged gallery visitors to oscillate between immersion and agency as they occupy the various perspectives proposed by the installation.

Purpose – The purpose of this paper is to provide a critical analysis of recent examples of action competence among young people engaged in democratic participatory action in sustainability programs in Australia. It explores examples of priorities identified for citizen action, the forms this action takes and the ways that democratic participation can achieve positive outcomes for future sustainability. It suggests multiple ways for developing action competence that provides further opportunities for authentic and engaging citizen action for youth connected to school- and community-based learning, in new and powerful ways. Design/methodology/approach – This conceptual paper examines international literature on the theory of “action competence,” its significance for education for sustainability (EfS) and the ways it can inform education for young people’s democratic participatory citizenship and civic engagement. It analyses examples of the development of action competency among young people in Australia, including the problems and priorities identified for citizen action, the forms this action takes and how it can achieve positive outcomes for sustainability. Following this analysis, the paper suggests multiple ways for developing action competence in EfS in schools and communities in new and powerful ways. Findings – Developing EfS to increase democratic and participatory action among young citizens is now widely regarded as an urgent education priority. There are growing exemplars of school and community organizations’ involvement in developing EfS learning and teaching to increase participatory citizenship. Young people are being empowered to develop a greater sense of agency through involvement in programs that develop action competence with a focus on sustainability in and out of school. New forms of participation include student action teams and peer collaboration among youth who are marshaling social media and direction action to achieve change. Originality/value – It contributes to the literature on multiple ways for developing action competence in EfS.

It is the Journal of Business Venturing's (JBV) 30th birthday. Although the community of entrepreneurship scholars deserves to celebrate JBV's achievements over the last 30 years (and congratulate the journal's parents—Ian Macmillan and S. Venkataraman), my focus is more on the future of entrepreneurship (and by extension JBV). A focus on entrepreneurship is both timeless and timely. On the one hand, entrepreneurship is timeless given the long-recognized importance of entrepreneurs to economies and societies (e.g., Jean Baptiste who supposedly coined the term in about 1800). On the other hand, a discussion of entrepreneurship is timely because now that the field of entrepreneurship has achieved legitimacy, it faces both opportunities and threats. It is thus timely to acknowledge the threats and think about opportunities to advance the field. A discussion of entrepreneurship is also timely because society faces a number of grand challenges (including the durability of poverty, environmental degradation [ Dorado and Ventresca, 2013]), challenges well suited to entrepreneurial responses...

This study examines the Chinese press discussion about democratic centralism in 1978-1981 in newspapers, political journals and academic journals distributed nationwide. It is thus a study of intellectual trends during the Hua Guofeng period and of methods, strategies, and techniques of public political discussion of the time. In addition, this study presents democratic centralism as a comprehensive theory of democracy and evaluates this theory. It compares the Chinese theory of democratic centralism with Western traditions of democracy, not only with the standard liberal theory but also with traditions of participatory and deliberative democracy, in order to evaluate whether the Chinese theory of democratic centralism forms a legitimate theory of democracy. It shows that the Chinese theory comes close to participatory types of democracy and shares a conception of democracy as communication with the theory of deliberative democracy. Therefore, the Chinese experience provides some empirical evidence of the practicability of these traditions of democracy. Simultaneously, this study uses experiences of participatory democracies outside of China to explain some earlier findings about the Chinese practices. This dissertation also compares Chinese theory with some common Western theories and models of Chinese society as well as with Western understandings of Chinese political processes. It thus aims at opening more dialogue between Chinese and Western political theories and understandings about Chinese polity. This study belongs to scholarly traditions of the history of ideas, political philosophy, comparative politics, and China studies. The main finding of this study is that the Chinese theory of democratic centralism is essentially a theory about democracy, but whether its scrupulous practicing alone would be sufficient for making a country a democracy depends on which established definition of democracy one applies and on what kind of democratic deficits are seen as being acceptable within a truly democratic system. Nevertheless, since the Chinese theory of democratic centralism fits well with some established definitions of democracy and since democratic deficits are a reality in all actual democracies, the Chinese themselves are talking about democracy in terms acceptable to Western political philosophy as well.

They walked down through a dry creek bed lined with swamp gums grown so close together they appeared as one living whole. The men passed around these trees in single file, among sun shafts which pierced the canopy but threw no light upon their faces nor warmed their bones. In the gloom the air was thick with flies and the mushrooms grew like the sightless larvae of some queer and unnamed vermin. Before long they found themselves among a stand of trees which had been stripped of their bark for windbreaks. The naked trunks were carved over with bisected circles, detailings of the moon and sun, images of snakes and roo. The Parramatta men gazed at the finely wrought icons but John Batman found more to hold his attention. Pressed onto the flesh of the tree was a bloody handprint. Batman removed his hat and crouched to examine the ground and Black Bill joined him. One injured man had passed this way...
