An efficient solution for privacy-preserving, secure remote access to sensitive data

Sharing data that contains personally identifiable or sensitive information, such as medical records, always has privacy and security implications. The issues can become rather complex when the methods of access can vary, and accurate individual data needs to be provided whilst mass data release for specific purposes (for example for medical research) also has to be catered for. Although various solutions have been proposed to address the different aspects individually, a comprehensive approach is highly desirable. This paper presents a solution for maintaining the privacy of data released en masse in a controlled manner, and for providing secure access to the original data for authorized users. The results show that the solution is provably secure and maintains privacy in a more efficient manner than previous solutions.

The pharmaceutical industry, intellectual property rights and access to medicines in Pakistan

The pharmaceutical industry in Pakistan is worth around US$ l.18 billion, with annual growth in 2010 approaching 10 per cent (Khan, 2012). There are more than 650 registered companies, including 31 multinationals, which in 2006 had a market share in value terms of 53.3 per cent, with national firms controlling the remaining 46.7 per cent (IMS Health, 2007). In 2007 medicines worth about US$100 million were exported. Medicines are a vital component of healthcare, and Pakistan spends around three-quarters of its healthcare budget on medicines (WHO, 2004). This chapter provides an overview, from a public health perspective, of the national pharmaceutical market and the development of drug policies and regulation. Pakistan adopted a Trade Related Aspects of Intellectual Property Rights (TRIPS) compliant patent regime in 2000, and the intersection between patents and public health is a central policy challenge. This chapter highlights key issues related to intellectual property, Free Trade Agreements (FTAs), and production and access to medicines.

Access to Health-Promoting Facilities and Amenities

This chapter provides a brief overview of the existing literature on the importance of the built environment to obesity and examines how local facilities, such as physical activity amenities, are distributed across different sorts of neighbourhoods. The issue of access to these facilities using different forms of transport (walking, cycling, bus or car) is explored using data from a Scotland wide study.

Sociospatial distribution of access to facilities for moderate and vigorous intensity physical activity in Scotland by different modes of transport

Background People living in neighbourhoods of lower socioeconomic status have been shown to have higher rates of obesity and a lower likelihood of meeting physical activity recommendations than their more affluent counterparts. This study examines the sociospatial distribution of access to facilities for moderate or vigorous intensity physical activity in Scotland and whether such access differs by the mode of transport available and by Urban Rural Classification. Methods A database of all fixed physical activity facilities was obtained from the national agency for sport in Scotland. Facilities were categorised into light, moderate and vigorous intensity activity groupings before being mapped. Transport networks were created to assess the number of each type of facility accessible from the population weighted centroid of each small area in Scotland on foot, by bicycle, by car and by bus. Multilevel modelling was used to investigate the distribution of the number of accessible facilities by small area deprivation within urban, small town and rural areas separately, adjusting for population size and local authority. Results Prior to adjustment for Urban Rural Classification and local authority, the median number of accessible facilities for moderate or vigorous intensity activity increased with increasing deprivation from the most affluent or second most affluent quintile to the most deprived for all modes of transport. However, after adjustment, the modelling results suggest that those in more affluent areas have significantly higher access to moderate and vigorous intensity facilities by car than those living in more deprived areas. Conclusions The sociospatial distributions of access to facilities for both moderate intensity and vigorous intensity physical activity were similar. However, the results suggest that those living in the most affluent neighbourhoods have poorer access to facilities of either type that can be reached on foot, by bicycle or by bus than those living in less affluent areas. This poorer access from the most affluent areas appears to be reversed for those with access to a car.

Challenges redoubled: contexts of risk and compromised access to services for children with sexualised behaviours

 Clinical studies indicate that children who engage in coercive or aggressive sexual acts are more likely to come from conditions of developmental adversity. Broadly speaking, the context of risk for children engaging in these behaviours aligns with particular indicators of social exclusion; geographic disadvantage, compromised family functioning and poverty. Children from such conditions of adversity are thought to be doubly compromised, as the context of risk that gave rise to the behaviours may also compromise families’ engagement with specialised therapeutic services to modify a child’s behaviours. In the absence of empirical data on the prevalence of problem sexual behaviours in Australia, this paper suggests that that scholarship and data collection underpinning the social inclusion policy agenda may inform the targeted delivery of secondary prevention strategies for children most at risk of engaging in problem sexual behaviours.

Extensions to knowledge acquisition and effect of multimodal representation in unsupervised learning

The phenomenal behaviour and composition of human cognition is yet to be defined comprehensibly. Developing the same, artificially, is a foremost research area in artificial intelligence and related fields. In this chapter we look at advances made in the unsupervised learning paradigm (self organising methods) and its potential in realising artificial cognitive machines. The first section delineates intricacies of the process of learning in humans with an articulate discussion of the function of thought and the function of memory. The self organising method and the biological rationalisations that led to its development are explored in the second section. The next focus is the effect of structure restrictions on unsupervised learning and the enhancements resulting from a structure adapting learning algorithm. Generation of a hierarchy of knowledge using this algorithm will also be discussed. Section four looks at new means of knowledge acquisition through this adaptive unsupervised learning algorithm while the fifth examines the contribution of multimodal representation of inputs to unsupervised learning. The chapter concludes with a summary of the extensions outlined.

Widening access to lifelong learning for adults in Ethiopia: opportunities with recognition of prior learning

Socio-economic implication of the lifelong learning for all agenda is enormous. The very idea of lifelong learning frees learning from time and space constraints. It advocates learning to be an activity of a lifetime both within and without the formal education system. The assumption is that lifelong and life-wide learning will promote competitiveness, creativity, employability and social cohesion. Taking it in the context of developing countries such as Ethiopia, lifelong learning as an educational organising principle may play a vital role in supporting efforts to eradicate illiteracy and reduce poverty. Recently, Ethiopia has introduced the third phase of their education sector development programme, which underscores the importance of adult education, and a national strategy for adult education. This paper analyses the two documents to understand the extent to which non-formal and formal education are linked, and thereby to highlight the significance of institutionalising the recognition of prior learning (RPL) to promote lifelong learning for adults and working population.
