    Evaluation of Dynamic Response and Brain Deformation Metrics for a Helmeted and Non-Helmeted Hybrid III Headform Using a Monorail Centric/Non-Centric Protocol
    Head injuries, and concussion in particular, have become a source of interest in the sport of ice hockey. This study proposes a monorail test methodology combined with a finite element method to evaluate ice hockey helmets in a centric/non-centric protocol with performance metrics more closely associated with risk of concussion. Two conditions were tested using the protocol: (a) helmeted versus no helmet, and (b) vinyl nitrile lined hockey helmet versus expanded polypropylene lined hockey helmet. The results indicate that the impact velocities and locations produced distinct responses. Also, the protocol distinguished important design characteristics of the two helmet liner types, with the vinyl nitrile lined helmet producing lower strain responses in the cerebrum. Furthermore, it was discovered that low risk of injury peak linear and rotational acceleration values can combine to produce much higher risks of injury when using brain deformation metrics. In conclusion, the use of finite element modeling of the human brain along with a centric/non-centric protocol provides an opportunity for researchers and helmet developers to observe how the dynamic response produced by these impacts influences brain tissue deformation and injury risk. This type of centric/non-centric physical to finite element modeling methodology could be used to guide innovation for new methods to prevent concussion.

    Supporting parents of adolescent perpetrators of CSA
    (Edwin Mellen Press, 2004) ; ; ;
    The importance of parental involvement in the treatment of their adolescent CSA perpetrators cannot be underestimated. One of the defining differences between the fields of adult and adolescent sexual offending is the fact that adolescents are still in a formative stage of development. Parents can still exercise a major influence in re-engaging children back on a normative developmental pathway and reducing future risk to a minimum. It is also important to include parents of adolescent CSA perpetrators in treatment programmes because it is well documented in Irish and international studies that some have significant problems.

    A comparison of two CSA treatment programmes
    The development of effective treatment programmes to ameliorate the sequelae of CSA is imperative. Ideally such programmes should address intrapsychic psychological difficulties through individually based child-focused interventions; peer-related interpersonal problems through group-based interventions; and difficulties within the family and wider social network through family therapy and systemic interventions. It would be expected that some programmes might be more effective than others for young people with particular constellations of difficulties and that programmes that combined two or more therapeutic modalities might be more effective than more narrowly focused programmes.

    Profiles of parents of adolescent perpetrators of CSA
    (Edwin Mellen Press, 2004) ; ; ;
    The present study aimed to expand our knowledge about the profiles of families of adolescent CSA perpetrators by comparing a group of parents of adolescent sexual offenders (PASO); a clinical control group (CC) of parents of non-offending adolescents attending a child and adolescent mental health service; and a normal control group (NC) of parents of non-offending adolescents in the community on a range of demographic, developmental, personal adjustment and family environment variables.

    Profiles of adolescent perpetrators of CSA
    Studies of the psychological adjustment of adolescents who sexually abuse other youngsters have shown that they differ from normal control groups, and hold some features in common with clinical control groups with other psychological problems and incarcerated control groups convicted of non-sexual offences. For example, they show more behaviour problems than normal controls but not incarcerated controls; they have difficulties with making and maintaining friendships and establishing empathy with others; they have problems with impulse control, anger management and assertiveness; and they come from families characterized by a variety of problems. Despite the burgeoning international literature in this area, few studies have been conducted on Irish adolescent sexual abusers and non-adjudicated abusers.
