In species where young are provisioned by both parents, males commonly contribute less to parental care than females, and are less responsive to variation in begging rates. Similar differences in the care of young occur among adults in cooperative breeders, but fewer studies have investigated whether these are associated with differences in responsiveness. Here, we present results from a playback experiment investigating responsiveness to begging in the meerkat (Suricata suricatta), a cooperatively breeding mammal. Although increased begging rate raised the feeding rate of adults of both sexes, there was no consistent tendency for females to be more responsive than males. However, when we examined changes in the proportion of food items found that were fed to pups (generosity), we found that females were more responsive than males to increased begging rate. These results can be explained in terms of sex differences in dispersal: in meerkats, females are philopatric and receive considerable benefits from investing in young, both directly, by increasing group size, and indirectly, by recruiting helpers if they inherit the breeding position. In addition, they emphasize that generosity provides a more sensitive measure of responsiveness to begging than feeding rate, as it accounts for variation in foraging success. © 2008 The Royal Society.

The study examined lateral preference in use of hands, feet, eyes, and ears in a group of nearly 5000 schoolchildren in Northern Ireland. Performance tests were carried out by student teachers during their school-based work in 2002 and data were submitted on-line. Six tasks were used-writing, throwing a ball, kicking a ball, hopping, listening to quiet sounds, and looking through a cardboard tube. There was right bias in every task but the extent of it differed between tasks. Males were generally less right biased than females, and younger children less than older ones; for hearing, the changes with age were markedly different in the two sexes, with females showing a strong increase in right bias but males showing none. These observational results do little to illuminate the reasons for the patterns observed.

With age, children process information more rapidly, thus increasing access to and retrieval of information from memory. This speed of information processing is often explained in terms of automaticity. The present study explores this suggestion with respect to primary schoolchildren; 173 pupils aged between 7 and 11 years were tested using a chronometric paradigm. Analysis indicated a highly significant maturational trend towards greater automaticity across all age-groups. However, the results failed to provide evidence for sex differences in automaticity, nor was there evidence of an interaction between age and sex.

For more than a decade the Peace Process has fundamentally changed Northern Irish society. However, although socioreligious integration and ethnic mixing are high on the political agenda in Northern Ireland, the Peace Process has so far failed to address the needs of some of the most vulnerable young people, for example, those who identify as gay, lesbian, or bisexual. Public debates in Northern Ireland remain hostile to same-sex-attracted people. Empirical evidence from the annual Young Life and Times (YLT) survey of 16-year-olds undertaken by ARK shows that same-sex-attracted young people report worse experiences in the education sector (e.g., sex education, school bullying), suffer from poorer mental health, experience higher social pressures to engage in health-adverse behavior, and are more likely to say that they will leave Northern Ireland and not return. Equality legislation and peace process have done little to address the heteronormativity in Northern Ireland.

“Megan’s Law” in the United States and Part 1 of the Sex Offenders Act 1997 in the United Kingdom, make provision for the creation of a register which will record the names and addresses of all persons convicted or cautioned for a sexual offence. Arguments expounded in favour of the legislation include the supposedly high recidivism among sex offenders, the inadequacy of supervision provisions, and the resulting need to ‘track’ the dangerous offender for public protection. In practice, however, there are a plethora of obstacles, such as cost and inadequate policing resources, which may impede its effectiveness in aiding law enforcement and reduce it to symbolic significance only. In addition, there are an array of ethical objections to the legislation, such as it breaches civil liberties and constitutes ‘double jeopardy’, which may prevent meaningful imposition.

The aim of this paper is to explore the implications and difficulties of a system of sex offender registration for Northern Ireland and the Republic of Ireland. From the orthodox perspective, registration appears justified. Sexual offending has increased and this is used by the media to generate a ‘moral panic’. However, sexual offenders in the community have also been socially constructed in Ireland, as a problem requiring specific action, through Blumer’s (1971) developmental perspective. It is this perspective which most adequately explains the formulation of the legislation. Arguments expounded in favour of registration include the supposedly high recidivism among sex offenders, the inadequacy of supervision provisions and the resulting need to ‘track’ the offender for public protection. Yet, in practice there are a plethora of obstacles such as cost and inadequate policing resources, not considered at the time the legislation was being formulated, which may impede its effectiveness in aiding law enforcement and reduce it to symbolic significance only. Given these difficulties, it is argued that registration is not an appropriate response to the problem of released sexual offenders in Ireland. Rather, from the social constructionist perspective, it is suggested that it is better to ‘treat’ the sex offender through less formal and stringent means in the community away from the criminal justice process.
