Major food adulteration and contamination events occur with alarming regularity and are known to be episodic, with the question being not if but when another large-scale food safety/integrity incident will occur. Indeed, the challenges of maintaining food security are now internationally recognised. The ever increasing scale and complexity of food supply networks can lead to them becoming significantly more vulnerable to fraud and contamination, and potentially dysfunctional. This can make the task of deciding which analytical methods are more suitable to collect and analyse (bio)chemical data within complex food supply chains, at targeted points of vulnerability, that much more challenging. It is evident that those working within and associated with the food industry are seeking rapid, user-friendly methods to detect food fraud and contamination, and rapid/high-throughput screening methods for the analysis of food in general. In addition to being robust and reproducible, these methods should be portable and ideally handheld and/or remote sensor devices, that can be taken to or be positioned on/at-line at points of vulnerability along complex food supply networks and require a minimum amount of background training to acquire information rich data rapidly (ergo point-and-shoot). Here we briefly discuss a range of spectrometry and spectroscopy based approaches, many of which are commercially available, as well as other methods currently under development. We discuss a future perspective of how this range of detection methods in the growing sensor portfolio, along with developments in computational and information sciences such as predictive computing and the Internet of Things, will together form systems- and technology-based approaches that significantly reduce the areas of vulnerability to food crime within food supply chains. As food fraud is a problem of systems and therefore requires systems level solutions and thinking.

This chapter describes my experiences of conducting research on commercial sex in Belfast, Northern Ireland which was conducted as part of a larger British Academy – Leverhulme Trust funded study that examined the policing and legal regulation of commercial sex in Belfast (Northern Ireland) along with three other cities: Manchester (England), Berlin (Germany) and Prague (Czech Republic). This study provided the first empirical analysis of commercial sex in the jurisdiction and was instrumental in shedding light on prevalence rates for those involved in the industry as well as providing demographic information on the age, nationality and sexual orientation of sex workers along with the sector worked in, whether on-street or off-street. In the chapter I consider my role as a researcher and highlight some of the difficulties that I experienced conducting what was seen as controversial research in the politically, socially and culturally conservative context of Northern Ireland.
