Keeping in constant touch : the predictors of young Australians’ mobile phone involvement

Little is known about the psychological underpinnings of young people’s mobile phone behaviour. In the present research, 292 young Australians, aged 16–24 years, completed an online survey assessing the effects of self-identity, in-group norm, the need to belong, and self-esteem on their frequency of mobile phone use and mobile phone involvement, conceptualised as people’s degree of cognitive and behavioural association with their mobile phone. Structural equation modelling revealed that age (younger) and self-identity significantly predicted the frequency of mobile phone use. In contrast, age (younger), gender (female), self-identity and in-group norm predicted young people’s mobile phone involvement. Neither self-esteem nor the need to belong significantly predicted mobile phone behaviour. The present study contributes to our understanding of this phenomenon and provides an indication of the characteristics of young people who may become highly involved with their mobile phone.

Life on the edge : housing experiences in three remote Australian indigenous settlements

This analysis of housing experiences and aspirations in three remote Indigenous settlements in Australia (Mimili, Maningrida and Palm Island) reveals extreme liveability problems directly related to the scale and form of housing provision. Based upon field visits to each of the settlements and extensive interviews with residents and local housing and community officers, the paper analyses two aspects of living in such housing conditions at two spatial scales, the layout of the settlement and the design of individual houses. The failings at both scales are shown to be the fault of a dysfunctional housing system that is only recently been addressed.

Full circle : the future of sustainable fashion manufacturing in New Zealand

Many fashion businesses in New Zealand have followed a global trend towards inexpensive off shore manufacturing. The transfer of the production of garments to overseas workers has had consequences for the wellbeing of local businesses, fashion designers and garment makers. The gradual decline of fashion manufacturing also appears to have resulted in a local fashion scene where many garments look the same in style, colour, fabric, cut and fit. The excitement of the past, where the majority of fashion designers established their own individuality through the cut and shape of the garments that they produced, may have been inadvertently lost in an effort to take advantage of cost savings achieved through mass production and manufacturing methods which are now largely unavailable in New Zealand. Consequently, a sustainable local fashion and manufacturing industry, with design integrity, seems further out of reach. This paper is focussed upon the thesis that the design and manufacture of a fashion garment, bearing in mind certain economic and practical restrictions at its inception, can contribute to a more sustainable fashion manufacturing industry in New Zealand.

Youth theatre and the articulation of cultural capital : refocusing Bourdieu through ethnography

This study of working-class and middle-class youth theatre workshops examines the processes through which this cultural form is appropriated by different class groups. Whereas the middle-class workshop proceeded efficiently and harmoniously, the working-class group resisted a number of institutional constraints traditionally associated with play rehearsal and performance. The processes of such symbolic struggle in the working-class group appeared to differ from Bourdieu's account of cultural domination. The article explores the explanatory contribution of the ethnographic case study to the analysis of the class basis of cultural tastes and practices and suggest that Bourdieu's account of class relations would gain from inclusion of this level of analysis. The situated study of the youth theatre workshops suggests that at this level, there is possibly more scope for symbolic struggle between the classes than was found by Bourdieu.

Planning for knowledge based urban development in Malaysia : Cyberjaya @ Multimedia Super Corridor

Knowledge based urban development (KBUD) is a new paradigm in urban planning tailoring to the era of knowledge economy. It aims mainly to assist a contemporary city to promote a more sustainable socio-spatial order. The paper reports on the investigation of KBUD initiative in Malaysia which is manifested through the establishment of a project called Multimedia Super Corridor (MSC). MSC Malaysia aims to attract knowledge workers and industries to invest and operate within the area by creating a world class urban corridor with state-of-the-art multimedia infrastructure, efficient transportation system and an attractive living environment. Based on documents analysis and interviews, this paper analyses the strategies, implementations, and achievements of KBUD initiative in Cyberjaya, being the leading intelligent city of the unique Malaysia’s KBUD project-MSC Malaysia. A critical evaluation is made to assess the achievements of MSC, by looking at the physical changes after about ten years since its official launching. The findings recommend some valuable lessons for other cities that strive to develop KBUD strategies, strengthen their sustainable socio-spatial policies, and seek a global recognition.

Attractive subfamilies of BLS curves for implementing high-security pairings

Barreto-Lynn-Scott (BLS) curves are a stand-out candidate for implementing high-security pairings. This paper shows that particular choices of the pairing-friendly search parameter give rise to four subfami- lies of BLS curves, all of which offer highly efficient and implementation- friendly pairing instantiations. Curves from these particular subfamilies are defined over prime fields that support very efficient towering options for the full extension field. The coefficients for a specific curve and its correct twist are automat-ically determined without any computational effort. The choice of an extremely sparse search parameter is immediately reflected by a highly efficient optimal ate Miller loop and final exponentiation. As a resource for implementors, we give a list with examples of implementation-friendly BLS curves through several high-security levels.

Deep Raman spectroscopy for the non-invasive standoff detection of concealed chemical threat agents

Deep Raman spectroscopy has been utilized for the standoff detection of concealed chemical threat agents from a distance of 15 meters under real life background illumination conditions. By using combined time and space resolved measurements, various explosive precursors hidden in opaque plastic containers were identified non-invasively. Our results confirm that combined time and space resolved Raman spectroscopy leads to higher selectivity towards the sub-layer over the surface layer as well as enhanced rejection of fluorescence from the container surface when compared to standoff spatially offset Raman spectroscopy. Raman spectra that have minimal interference from the packaging material and good signal-to-noise ratio were acquired within 5 seconds of measurement time. A new combined time and space resolved Raman spectrometer has been designed with nanosecond laser excitation and gated detection, making it of lower cost and complexity than picosecond-based laboratory systems.

GATEKEEPING, GATEWATCHING, REALIMENTAÇÃO EM TEMPO REAL: novos desafios para o Jornalismo

Faz vários anos que se sabe como os blogueiros e outros comentaristas on-line independentes criticam, corrigem, e de outra maneira desafiam o jornalismo convencional, porém isto ainda não foi plenamente aceito pelos jornalistas; as hostilidades entre as empresas de mídia e a nova geração de jornalistas cidadãos continuam a irromper de vez em quando. O antigo monopólio de gatekeeping mantido pela mídia de massa tem sido desafiado pela nova prática de gatewatching: feita pelos blogueiros individuais e pelas comunidades de comentaristas que podem não fazer reportagem das notícias de primeira mão, porém fazem a curation e avaliam as notícias e outras informações fornecidas pelas fontes oficiais, e assim prestam um serviço importante. E isto ocorre atualmente com cada vez mais rapidez, quase em tempo real: usando as redes sociais mais recentes, que divulgam, compartilham, comentam, questionam e desacreditam as matérias noticiosas dentro de minutos, e usando plataformas adicionais que possibilitam a colaboração ad hoc rápida e eficaz entre os usuários. Quando centenas de voluntários podem provar dentro de alguns poucos dias que um ministro alemão foi culpado de plágio sério, quando o mundo inteiro fica sabendo de terremotos e tsunamis pelo Twitter – como é que o jornalismo consegue acompanhar tudo isto?

Conflict or consensus : an investigation of stakeholder concerns during the participation process of major infrastructure and construction projects in Hong Kong

Public participate in the planning and design of major public infrastructure and construction (PIC) projects is crucial to their success, as the interests of different stakeholders can be systematically captured and built into the finalised scheme. However, public participation may not always yield a mutually acceptable solution, especially when the interests of stakeholders are diverse and conflicting. Confrontations and disputes can arise unless the concerns or needs of the community are carefully analysed and addressed. The aim of the paper is to propose a systematic method of analysing stakeholder concerns relating to PIC projects by examining the degree of consensus and/or conflict involved. The results of a questionnaire survey and a series of interviews with different entities are provided, which indicate the existence of a significant divergence of views among stakeholder groups and that conflicts arise when there is a mismatch between peoples’ perception concerning money and happiness on the one hand and development and damages on the other. Policy and decision-makers should strive to resolve at least the majority of conflicts that arise throughout the lifecycle of major PIC projects so as to maximise their chance of success.

Access, progress, and fairness : rethinking exclusivity in copyright

This article provides a detailed critique of the incentives-access binary in copyright discourse. Mainstream copyright theory generally accepts that copyright is a balance between providing incentives to authors to invest in the production of cultural works and enhancing the dissemination of those works to the public. This Article argues that dominant copyright theory obscures the possibility of developing a model of copyright that is able to support authors without necessarily limiting access to creative works. The abundance that the Internet allows suggests that increasing access to cultural works to enhance learning, sharing, and creative play should be a fundamental goal of copyright policy. This Article examines models of supporting and coordinating cultural production without exclusivity, including crowdfunding, tips, levies, restitution, and service-based models. In their current forms, each of these models fails to provide a cohesive and convincing vision of the two main functions of copyright: instrumentally (how cultural production can be funded) and fairness (how authors can be adequately rewarded). This article provides three avenues for future research to investigate the viability of alternate copyright models: (1) a better theory of fairness in copyright rewards; (2) more empirical study of commons models of cultural production; and (3) a critical examination of the noneconomic harm limiting function that exclusivity in copyright provides.

Hydrothermal technologies for the production of fuels and chemicals from biomass

Biomass and non-food crop residues are seen as relatively low cost and abundant renewable sources capable of making a large contribution to the world’s future energy and chemicals supply. Signifi cant quantities of ethanol are currently produced from biomass via biochemical processes, but thermochemical conversion processes offer greater potential to utilize the entire biomass source to produce a range of products. This chapter will review thermochemical gasifi cation and pyrolysis methods with a focus on hydrothermal liquefaction processes. Hydrothermal liquefaction is the most energetically advantageous thermochemical biomass conversion process. If the target is to produce sustainable liquid fuels and chemicals and reduce the impact of global warming as a result of carbon dioxide, nitrous oxide, and methane emissions (i.e., protect the natural environment), the use of “green” solvents, biocatalysts and heterogeneous catalysts must be the main R&D initiatives. As the biocrude produced from hydrothermal liquefaction is a complex mixture which is relatively viscous, corrosive, and unstable to oxidation (due to the presence of water and oxygenated compounds), additional upgrading processes are required to produce suitable biofuels and chemicals.
