This paper draws on exploratory research examining the sexual and ageing identities of gay men in England and the way in which these affect welfare needs and service use experiences. In this case, the focus is not upon the research findings per se, but on the research methods used to elucidate them. The author theorises about the ways in which the qualitative interviewing that took place was influenced by his age, homosexuality, and gender during the interaction with older gay men. The conclusions are that the shared gender and sexual orientation (although not without their differences) were crucial to the successful completion of the research and in trying to ensure participants felt valued and empowered. Therefore, it is asserted from this that increasingly reflexive research is paramount to the development of qualitative methodologies and gerontology, to ensure the academe is inclusive of diverse identities and that its research stands up to rigorous scrutiny.

A critical component of aviation security consists of screening passengers and baggage to protect airports and aircraft from terrorist threats. Advancements in screening device technology have increased the ability to detect these threats; however, specifying the operational configurations of these devices in response to changes in the threat environment can become difficult. This article proposes to use Fisher information as a statistical measure for detecting changes in the threat environment. The perceived risk of passengers, according to prescreening information and behavior analysis, is analyzed as the passengers sequentially enter the security checkpoint. The alarm responses from the devices used to detect threats are also analyzed to monitor significant changes in the frequency of threat items uncovered. The key results are that this information‐based measure can be used within the Homeland Security Advisory System to indicate changes in threat conditions in real time, and provide the flexibility of security screening detection devices to responsively and automatically adapt operational configurations to these changing threat conditions.
