A Shared Future? Exclusion, Stigmatization, and Mental Health of Same-Sex-Attracted Young People in Northern Ireland

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.

Sex Offender Registration: Some Observations on ‘Megan’s Law’ and the Sex Offenders Act 1997

“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.

Sex Offender Registration: Implications and Difficulties for Ireland

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.

Sex, drugs and STDs: Preliminary findings from the Belfast Youth Development Study

Young people's participation in sexual risk behaviours is commonly linked with participation in a range of other risky behaviours, and in particular with substance use behaviours. This cross-sectional analysis of the sixth sweep of the Belfast Youth Development Study aimed to examine associations between substance use and sexual activity and related risks among 17-19-year olds in Northern Ireland. Being sexual activity and participating in sexual risk behaviours was associated with the use of a range of licit and illicit substances particularly alcohol and ecstasy. Additionally, females were more likely to have been tested for a sexually transmitted disease (STD). The findings add to the existing research body suggesting that substance misuse and sexual risk behaviours tend to co-occur in adolescence and highlight a need to develop appropriate interventions and initiatives for school aged young people.

Biosensor-based detection of reduced sex hormone-binding globulin binding capacities in response to growth-promoter administrations

Growth-promoting agents are illicitly used during animal rearing processes and the detection of their use is limited by new compounds and dosing practices that limit the efficiency of current testing which is based on residue analysis by liquid chromatography–tandem mass spectrometry (LC–MS/MS) and gas chromatography–mass spectrometry (GC–MS) methodology. An alternative approach is to use indirect biological evidence as a screening tool to identify growth-promoter treated animals thus improving the effectiveness of residue testing through the targeted sampling of these animals. Sex hormone-binding globulin (SHBG) is a glycoprotein which binds and controls the levels of sex-hormones within the circulation. Using a biosensor assay based on measurement of binding to an immobilised 1a-dihydrotestosterone (1a-DHT) derivative, reduced SHBG binding capacities were detected in growth-promoter treated animals. During the course of a veal treatment regime based on repeated oestradiol benzoate, nortestosterone decanoate and dexamethasone administrations, treated male and female calves were shown to have significantly lower SHBG capacities. To assess the effectiveness of using SHBG binding capacities as a biomarker of treatment and to investigate the role of individual growth-promoter components to the SHBG capacity lowering effects, adult heifer animals were subjected to repeated doses of nortestosterone decanoate. These animals also demonstrated a reduction in SHBG capacity levels at Day 39 of the study, in contrast to oestradiol benzoate treated adult steers who were found to have unaltered levels. These findings suggest that the measurement of SHBG binding capacities using a biosensor assay has potential in the identification of illegally treated animals, particularly those exposed to androgens.

Body mass and sex-biased parasitism in wood mice Apodemus sylvaticus

Male sex-biased parasitism (SBP) occurs across a range of mammalian taxa and two contrasting sets of hypotheses have been suggested for its establishment. The first invokes body size per se and suggests that larger individuals are either a larger target for parasites, trade off growth at the expense of immunity or cope better with parasitism than smaller individuals. The second suggests a sex-specific handicap whereby males have reduced immunocompetence compared to females due to the immunodepressive effects of testosterone. The current study investigated whether sex-biased parasitism is driven by host 'body size' or 'sex' using a rodent-tick (Apodemus sylvaticus-. Ixodes ricinus) system. Moreover, the presence or absence of large mammals at study sites were used to control the presence of immature ticks infesting wood mice, allowing the impacts of parasitism on host body mass and female reproduction to be assessed. As expected, male mice had greater tick loads than females and analyses suggested this sex-bias was driven by body mass as opposed to sex. It is therefore likely that larger individuals are a larger target for parasites, trade off growth at the expense of immunity or adapt behavioural responses to parasitism based on their body size. Parasite load had no effect on host body mass or female reproductive output suggesting individuals may alter behaviour or life history strategies to compensate for costs incurred through parasitism. Overall, this study lends support to the 'body size' hypothesis for the formation of sex-biased parasitism.

Protracted rainfall decreases temperature within leatherback turtle (Dermochelys coriacea) clutches in Grenada, West Indies: Ecological implications for a species displaying temperature dependent sex determination

Protracted or intense rainfall may affect the reproductive success of reptilian species on a number of levels ranging from the availability of prey, the integrity of the nesting site and the subsequent survivability of offspring. For sea turtles (a species displaying temperature sex determination) nesting throughout the tropics and subtropics, rainfall has previously been shown to influence the development environment of clutches; in its extreme resulting in high levels of egg or hatchling mortality. Yet when compared to other abiotic variables affecting clutch success, rainfall has received relatively little attention. We therefore examined how fluctuations in local rainfall at a tropical nesting site for leatherback turtles (Dermochelys coriacea) affected the nest environment. Temperature data loggers placed within clutches (n = 8) revealed that protracted rainfall had a marked cooling effect on nests, so that seasonally improbable male-producing temperatures (

Thermal conditions in nests of loggerhead turtles: further evidence suggesting female skewed sex ratios of hatchling production in the Mediterranean

Temperature was recorded in 23 nests of the loggerhead turtle (Caretta caretta) and control sites of nest depth at Alagadi (35 degrees 33'N, 33 degrees 47'E), Northern Cyprus, eastern Mediterranean. Control site sand temperature was found to be highly correlated with mean daily air temperature and mean nest temperature. Mean temperature in nests ranged from 29.5 degreesC to 33.2 degreesC, with mean temperature in the middle third of incubation ranging from 29.3 degreesC to 33.7 degreesC. Hatching success was significantly correlated with incubation temperature, with nests experiencing very high temperatures exhibiting low hatching success. All nests demonstrated regular diel variation in temperature with mean daily fluctuations ranging from 0.3 degreesC to 1.4 degreesC. Increase in temperature above that of the prevailing sand temperature attributed to metabolic heating was clearly demonstrated in 14 of 15 clutches, with the mean level of metabolic heating of all nests being 0.4 degreesC. However, the level of metabolic heating varied markedly throughout the incubation period with levels being significantly higher in the final third of incubation. Incubation duration was found to be significantly correlated to both the mean temperature of nests throughout the incubation period and during the middle third of incubation. The relationship between incubation duration and mean incubation temperature was used to estimate mean incubation temperatures at most major nesting sites throughout the Mediterranean from available data on incubation durations, showing that mean incubation temperature is likely to be above 29.0 degreesC at most sites in most seasons.
