Recent sexual health promotion strategies have veered between a negative emphasis on the deleterious consequences of sexually transmitted infections, and a more positive, eroticized approach to safer sex. The differences in approach are starkly reflected in the images chosen to illustrate them. We note that there are problems with both approaches. The main purpose of this review is to demonstrate how this dichotomy was transcended by the sixteenth century Florentine Mannerist painter, Agnolo Bronzino, in his allegory on syphilis

This article examines the state regulation of sexual offenders in the particular context of pre-employment vetting. A successive range of statutory frameworks have been put in place, culminating in the Safeguarding Vulnerable Groups Act 2006, to prevent unsuitable individuals from working with the vulnerable, and children in particular. Contemporary legislative and policy developments are set against a backdrop of broader concerns in the area of crime and justice, namely risk regulation, preventative governance and ‘precautionary logic.’ Proponents of these approaches have largely ignored concerns over their feasibility. This article specifically addresses this fissure within the specific field of vetting. It is argued that ‘hyper innovation’ and state over-extension in this area are particularly problematic and have resulted in exceptionally uncertain and unsafe policies. These difficulties relate principally to unrealistic public expectations about the state’s ability to control crime; unintended and ambiguous policy effects; and ultimately the failure of the state to deliver on its self-imposed regulatory mandate to effectively manage risk.

In the last number of years the management of the dangerous in the community, particularly sex offenders, has generated enormous concern. This concern has been reflected at a number of different levels - in media and popular responses to the risk posed by released sex offenders in the community and in official discourses where an abundance of legislation and policy reforms have been enacted within a relatively short period of time. This analysis seeks to critically evaluate these developments within the context of contemporary criminal justice policy and practice in relation to the management of sex offenders in the community. The article analyses the contemporary focus on risk management or preventative governance which underpins the current regulatory framework and has been reflected in both the sentencing options and in control in the community initiatives for sex offenders. In this respect, the article highlights the gap between policy and practice in terms of the effective risk management of sex offenders. Given the failure of the traditional justice system with respect to these types of offences, it will be argued that the retributive framework could usefully be supplemented by the theory and practice of reintegrative or restorative community justice, and public education in particular, in order to better manage the risk presented by sex offenders in the community.

A key component of parental care involves defending resources destined for offspring from a diverse array of potential interspecific competitors, such as social parasites, fungi and bacteria. 2. Just as with other aspects of parental care, such as offspring provisioning or brood defence, sexual conflict between parents may arise over how to share the costs of this form of care. There has been little previous work, however, to investigate how this particular burden might be shared. 3. Here, we describe a hitherto uncharacterized form of parental care in burying beetles Nicrophorus vespilloides, a species which prepares carrion for its young and faces competition from microbes for this resource. We found that parents defend the carcass with antibacterial anal exudates, and that the antibacterial activity of these exudates is only upregulated following the discovery of a corpse. At the same time, phenoloxidase activity in the anal exudates is downregulated, indicating parallels with the internal insect immune system. 4. In unmanipulated breeding pairs, females had higher antibacterial activity in their anal exudates than males, suggesting sex-specific roles in this aspect of parental care. 5. When we experimentally widowed males, we found that they increased levels of antibacterial activity in their anal exudates. Experimentally widowing females, however, led them to decrease levels of antibacterial activity in their anal exudates. Widowed beetles of each sex thus produced anal exudates of comparable antibacterial activity. We suggest that this flexible division of antibacterial activity may be coordinated by Juvenile Hormone. © 2009 British Ecological Society.
