Algebraic attacks over GF(q)

Recent algebraic attacks on LFSR-based stream ciphers and S-boxes have generated much interest as they appear to be extremely powerful. Theoretical work has been developed focusing around the Boo- lean function case. In this paper, we generalize this theory to arbitrary finite fields and extend the theory of annihilators and ideals introduced at Eurocrypt 2004 by Meier, Pasalic and Carlet. In particular, we prove that for any function f in the multivariate polynomial ring over GF(q), f has a low degree multiple precisely when two low degree functions appear in the same coset of the annihilator of f ^{q – 1} – 1. In this case, many such low degree multiples exist.

To keep me safe from harm? Transgender prisoners and the experience of imprisonment

The experience of imprisonment for a transgender person is often a terrifying one. He or she is extremely vulnerable in such an environment from sexual violence from other prisoners. In addition, he or she may be exposed to inadequate or inappropriate medical care. Consequently transgender prisoners are often denied the protection offered by role of law. A significant reason for this treatment is the erasure of the transgender experience in informing the nature of the prison regime. In particular, the failure to give sufficient weight to gender self identification by transgender prisoners exposes them to risks which other prisoners do not have to endure. It is suggested that the only way to reduce such harm is through the cultivation of a prison regime based upon the lives of transgender prisoners.

Finding a 'safe' place on the risk continuum: a case study of pregnancy and birthing in Lao PDR (Lao People's Democratic Republic)

This paper addresses two questions. Firstly: are the risk regimes faced, and perceived, by pregnant women in rural Lao PDR substantially different from those experienced by pregnant women in western societies? Secondly, if the Lao experiences and perceptions are different, can improvements in maternal health in Lao PDR be achieved without Laotians inheriting the risk regimes of late modernity experienced by many women in western societies? Secondary analysis is undertaken of data collected in 2005 for the evaluation of a pilot maternity waiting home in Bolikhan, Lao PDR. The results suggest significantly different risk perceptions and experiences between Lao and western communities, based on contrasting views of embodiment, identity construction and cosmologies. In the Lao rural communities studied, there is little evidence yet of 'risk society' despite the introduction of western technologies and practices to improve maternal mortality and morbidity. It is argued that 'risk society' can be avoided.

Masochistic marketing : Volvo Australia's not "so safe" strategy

Purpose – The objective is to describe a marketing approach used by Volvo in the Australian marketplace. It appears to be a rare approach and could be perceived to some extent as being “masochistic”.

Design/methodology/approach – The research is based upon a case study. The term “masochistic marketing” is introduced.

Findings – The “masochistic marketing” approach applied by Volvo in Australia should be seen as a process. It is dependent upon the outcome of a series of cause and effect relationships.

Research limitations/implications – The masochistic marketing approach may be divided into four cause-related phases, all of which create a dualistic outcome of either positive or negative effect-chains in respect to the corporate image in the marketplace and society.

Practical implications – A masochistic marketing approach is a high-risk venture. It is a challenging and demanding marketing process, because it plays on the humiliation of the corporate image itself. The core idea of the masochistic marketing approach violates, or at least appears to oppose, the fundaments of marketing.

Originality/value – Masochistic marketing is not recommended to be used as a common approach, unless a series of events has turned the corporate image in the marketplace into something that is highly undesirable and a stigma.

Review of the green consumers' perception formation about the environmentally safe products

This study examines the influence of various factors on the green purchase intention of customers in Australia. A conceptual model has been proposed and was subjected to empirical verification with the use of a survey of metropolitan and regional households in Victoria. The results indicate that corporate perception with respect of companies not placing higher priority on reducing pollution than increasing profitability was the significant predictor of customers’ negative overall perception toward environmentally safe products. The only positive contribution to customers’ perceptions was their past experience with the product. Other factors including the perception of environmentally safe products, product labels, and regulatory protection did not appear to influence customers’ perceptions. The results also suggest that customers are not tolerant of lower quality and higher prices of environmentally safe products. The present findings provide an understanding of the antecedents of green purchasing and highlight that green customers rely more on personal experience with the product rather than the information provided by the marketer.

Reducing harmful traditional practices in Adjibar, Ethiopia : lessons learned from the Adjibar safe motherhood project

This paper assesses the impact of the Adjibar Safe Motherhood Project and derives lessons of value to future interventions. Amongst the participatory qualitative methods used were 15 group discussions, eight semi-structured interviews, a number of opportunistic informal discussions and observation. The information gathering was complemented by a detailed review of project documents. Field visits for data collection took place over a six day period in March 2005. The project was effective in raising awareness about maternal health, and the social, economic and health consequences of various harmful traditional practices (HTPs). It has also mobilised the community to monitor and report HTPs and has strengthened referral systems for counselling, support and treatment. A number of effective strategies were identified as having contributed to project success. These are presented using the framework offered by the Ottawa Charter for Health Promotion which presents five areas of public health action: developing personal skills; strengthening community action; building healthy public policy; re-orienting health services; and, creating supportive environments. This evaluation contributes to and strengthens the expanding body of literature about effective development practices to reduce HTPs. It demonstrates that addressing HTPs takes time and long term investment; both are necessary to enable better understanding of the social and cultural reasons for HTPs before attempting to address them, and to build the community trust necessary to overcome the natural resistance to challenging such deeply entrenched practices. The project also highlighted the importance of developing a multi pronged strategy based on engagement with a broad range of stakeholders and supportive legislation.

Playing it safe : the influence of neighbourhood safety on children's physical activity − A review

Compared with previous generations, children spend less time playing outdoors and have lower participation rates in active transport. Many studies have identified lack of neighbourhood safety as a potential barrier to children's physical activity. This review describes concerns regarding ‘stranger danger’ and road safety, and discusses empirical studies that examine associations between neighbourhood safety and physical activity among youth. Variability of perceptions of safety between parents and youth are examined; ‘social traps’ are identified; and physical/social environmental interventions aimed at improving neighbourhood safety are discussed. A research agenda is suggested for further study of perceived and objective measures of neighbourhood safety and their associations with children's physical activity.

Producing animations to educate MSM and MSW to fashion safe sex practices and address low perceptions of personal risk

This project will produce animations in order to increase understandings of safe sex practices and address low perceptions of personal risk among two of the most vulnerable groups to HIV infection in Thailand. The animations will be incorporated into a prevention outreach program via Ipods, mobile phones and mobile-based portable devices to men who have sex with men (MSM) in their 'hide-outs', that is, parks, clubs and public toilets and male sex workers (MSW) in sex venues such as brothels, go-go bars and beats. To produce these animations, the project is first researching the sexual practices of MSM and MSW because of the lack of any substantive investigation of their social and sexual networks. This use of technology, informed by social research rather than behavioral studies, offers new possibilities to stem rapidly rising infection rates because it takes into account the diverse MSM and MSW identities. Overall, an estimated one- fifth (21%) of new HIV infections in Thailand occur in men who have unsafe sex with men. This disquieting increase highlights the fact that MSM are not adequately reached through HIV prevention programmes, most likely because little is known about their particular situations, contexts and practices.

The three delays as a framework for examining safe motherhood in Kafa zone, SNNPR, Ethiopia

The study examines delay as a crucial factor contributing to maternal mortality, using the conceptual framework of the Three Phases of Delay to explore factors that hinder the provision and utilisation of high quality, timely obstetric care in Kafa Zone, SNNPR, in Ethiopia. The Three Delays constitute the delay in deciding to seek medical care during an obstetric emergency, in reaching a medical facility, and in receiving suitable treatment in a health facility. Various aspects of the Three Delays are evaluated to examine problems of delay, transportation, and the referral system that is considered a vital element of the Ethiopian 'National Reproductive Health Strategy'.

Integrating nursing research education and practice : safe administration of medications

The integration of the best available evidence into the delivery of safe patient care is a challenging but important task. Southern Health in partnership with Deakin University embarked on a joint initiative to develop a culture of inquiry and evidencebased nursing practice.
