Health care has entered the electronic domain. This domain has improved data collection and storage abilities while allowing almost instantaneous access and results to data queries. Furthermore it allows direct communication between healthcare providers and health consumers. The development of privacy, confidentiality and security principles are necessary to protect consumers’ interests against inappropriate access. The electronic health systems vendors have dominated the transition of media, claiming it will improve the quality and coherence of the care process. However, numerous studies show that the health consumer is the important stakeholder in this process, and their views are suggesting that the electronic medium is the way forward, but not just yet. With the international push towards Electronic Health Records (EHRs) by the Health and Human Services (United States of America), National Health Service (United Kingdom), Health Canada (Canada) and more recently the Ministry of Health (New Zealand), this paper presents the consumers’ role with a focus on their perceptions on the security of EHRs. A description of a study, looking at the New Zealand health consumer, is given.

+ + +The purpose of this study was to create a ubiquitous proximity activated interactive digital display system providing adjusted artworks as content for evaluating viewer reactions and opinions to determine if similar interactive ubiquitous systems are a beneficial, enjoyable and even an appropriate way to display art. Multimedia used in galleries predominately provides content following set patterns and disregards the viewer. Interactive displays using viewer location usually require the viewer’s conscious participation through carrying some form of hardware or using expensive sensing equipment. We created an inexpensive, simple system that reacts to the user in a ubiquitous manner, allowing the evaluation of the usability and suitability of such systems in the context of viewing art. Results from testing show that interactive displays are generally enjoyed and wanted for displaying art, however even simple ubiquitous displays can cause user difficulty due to the transparency of their interaction.

+ + +The immune system is a complex and distributed system. It provides a multilayered form of defence, capable of identifying and responding to harmful pathogens that it does not recognise as “self”. The framework proposed in this paper incorporates a number of immunological concepts and principles, including the multilayered defence and the cooperation between cells in the adaptive immune system. An alternative model of positive selection is also presented. It is suggested that the framework discussed here could lead to reduced false positive responses in anomaly detection tasks, such as intrusion detection, as well being extended to a population of computational immune systems that are able to maintain population diversity of recognition and response.
