The talus: sex assessment of prehistoric New Zealand Polynesian skeletal remains

Prehistoric Polynesian skeletal remains are frequently being recovered in New Zealand due to the increasing pace of urbanisation. Since such material must often be reinterred quickly, it is important that the sex of individuals be determined from the remains in a relatively short time. For this purpose, discriminant function analysis was utilised for sex determination of prehistoric adult New Zealand Polynesian tali (24 males and 27 females). Five measurements were taken and subjected to Statistical Package for the Social Sciences (SPSS) discriminant function analysis. For the discriminant functions derived, accuracy of sex determination ranged from 85.1 to 93.3%. Reduction in error over random assignment by sex ranged from 70 to 87%.     

The calcaneus: sex assessment of prehistoric New Zealand Polynesian skeletal remains

The increasing pace of urbanisation has meant that prehistoric Polynesian skeletal remains are frequently being recovered in New Zealand. Since such material must often be reinterred quickly, it is important that the sex of individuals be determined from the remains in a relatively short time. For this purpose, discriminant function analysis was utilised for sex determination of prehistoric adult New Zealand Polynesian calcanei (26 male and 22 female). Five measurements were taken and subjected to Statistical Package for the Social Sciences (SPSS) discriminant function analysis. For the discriminant functions derived, accuracy of sex determination ranged from 88.4 to 93.5%. Reduction in error over random assignment by sex ranged from 77 to 87%.     

The femoral head: sex assessment of prehistoric New Zealand Polynesian skeletal remains

Prehistoric Polynesian skeletal remains are frequently being recovered in New Zealand due to the increasing pace of urbanisation. Since such material must often be reinterred quickly, it is important that the sex of individuals be determined from the remains in a relatively short time. For this purpose, discriminant function analysis was utilised for sex determination of prehistoric adult New Zealand Polynesian femora (47 male and 44 female). Three measurements of the femoral head were taken and subjected to Statistical Package for the Social Sciences (SPSS) discriminant function analysis. For the discriminant functions derived, accuracy of sex determination ranged from 80.9% to 82.4%. Reduction in error over random assignment by sex ranged from 62% to 65%.     

The articular surfaces of the hindfoot: sex assessment of prehistoric New Zealand Polynesian skeletal remains

Prehistoric Polynesian skeletal remains are frequently being recovered in New Zealand due to the increasing pace of urbanisation. Since such material must often be reinterred quickly, it is important that the sex of individuals be determined from the remains in a relatively short time. For this purpose, discriminant function analysis was utilised for sex determination of prehistoric adult New Zealand Polynesian tali (24 male and 27 females) and calcanei (26 males and 22 females). Two measurements of the trochlear articular surface of the talus and two measurements of the posterior talar articular surface of the calcaneus were taken and subjected to Statistical Package for the Social Sciences (SPSS) discriminant function analysis. For the single discriminant function derived, accuracy in sex determination was 92.3% and reduction in error over random assignment by sex was 85%.     

Articular surfaces of the pectoral girdle: sex assessment of prehistoric New Zealand Polynesian skeletal remains

Prehistoric Polynesian skeletal remains are frequently being recovered in New Zealand due to the increasing pace of urbanisation. Since such material must often be reinterred quickly, it is important that the sex of individuals be determined from the remains in a relatively short time. For this purpose, discriminant function analysis was utilised for sex determination of prehistoric adult New Zealand Polynesian clavicles (31 male and 31 female) and scapulae (33 male and 38 female). Diameters of the acromial and sternal ends of the clavicle and the height and breadth of the scapular glenoid cavity were measured and subjected to Statistical Package for the Social Sciences (SPSS) direct discriminant function analysis. For the single discriminant function derived, accuracy of sex determination was 97.7% and reduction in error over random assignment by sex was 95%. This discriminant function will be a useful tool in the assessment of human remains in the forensic and archaeological context because it incorporates measurements which can be taken on incomplete bones.     

Public attitudes to sex offenders in New Zealand

Abstract

Sexual offending is a topic that often invokes heated debate and strong opinions among individuals from all walks of life. Generally, those who commit crimes of a sexual nature are uniformly abhorred, especially those who sexually abuse children. While the presence of these views is widely acknowledged, little is known about what these views are or how they develop. This study aimed to answer this question by conducting focus groups in various centres around New Zealand. The results showed that the news media was identified as the most important source of information on sexual offenders, although there was some scepticism in regard to the veracity of such information. Some of the views expressed were consistent with current understandings of sexual offending while some appeared to be borne of a lack of information. The results are considered in light of current research and the implications and future directions for further research are discussed briefly.     

Geographical profiling in a novel context: prioritising the search for New Zealand sex offfenders

The present work explores the utility and value of geographical offender profiling methodologies within a novel context, considering both theoretical and practical issues relating to their application. The effectiveness of a well-known geographical profiling system, Dragnet, was tested across 101 New Zealand sex offence series, and findings compared with those derived for an equivalent sample from the UK. Average search costs (the amount of the total offence area that needed to be searched, starting from predicted offender home location, before the offender's actual home was reached) were far greater for the New Zealand sample than their UK offending counterparts. It is argued that this is because the spatial behaviour of New Zealand offenders violates many of the assumptions that Dragnet and other similar geographical profiling systems make in predicting offenders' home locations. Calibration of the system to the specific home-crime distance patterns of the New Zealand offenders did not enhance the efficacy of predictions made to a significant extent. It is consequently argued that, in their current form, geographical profiling systems are limited in their ability to account for samples displaying very different spatial characteristics to those that they were developed from and for. The implications of these findings for the general utility of geographical profiling are discussed, and ways in which systems might be developed in order to broaden their scope and applicability are suggested.     

The emotional intelligence of adult sex offenders: ability based EI assessment

Abstract

Previous research has suggested that sex offenders are deficient in several areas of emotional functioning such as empathy, emotional perception, emotional management and interpersonal functioning. It is unclear, however, whether sex offenders display a general deficit in emotional functioning or whether their emotional deficits are specific to the circumstances in which offences occur. The present study aimed to provide a broad assessment of the emotional functioning of sex offenders by assessing their emotional intelligence (EI) using an abilities-based emotional intelligence test. Nineteen sex offenders, 18 non-sex offending prisoners and 19 controls were administered the Perception, Assimilation and Management branch subtests from the Mayer Salovey Caruso Emotional Intelligence Test (MSCEIT). The results indicated that the sex offenders were not significantly different than the control group, as assessed by these three branches of the MSCEIT. The results lend support to the suggestion that the emotional deficits displayed by sex offenders may be offence-specific. Implications for the use of the MSCEIT in sex offending populations and the role of EI in relapse prevention programmes are discussed.     

New Zealand: Public Registers Report

In September 2007, the Commonwealth Law Bulletin (Vol. 33, No. 3), published an article on the New Zealand Law Commission’s Issues Paper on Public Registers (IP 3, 2007), including the four options for reform that the Commission was putting forward for consideration by interested persons.

The Law Commission’s Public Registers Report ¹ 1 New Zealand Law Commission’s Public Registers Report, NZLC R 101 2008. (the Report) has now been published, completing stage 2 of the Law Commission’s four stage Privacy Review.

It is available on the Law Commission’s website at http://www.lawcom.govt.nz.     

The approach of the New Zealand forensic scientist

Laboratory findings can be used by the police to guide their investigations, to clear the innocent or to indicate guilt in court proceedings. Although called by the prosecution the forensic scientist is in court to tell the whole truth and present impartial evidence to assist the court. His evidence should be clear to lay persons. The challenge of problems arising from daily work can extend the best scientists.     

The New Zealand Model of Family Group Conferencing

The Family Group Conference (FGC) originated in New Zealand where it is the foundation stone of the Youth Justice system introduced in 1989. A significant feature of that system is the way in which it enables restorative justice principles to be implemented in an integrated manner in a statutory framework supervised by the courts and applicable to all young offenders throughout New Zealand. FGCs are used both as a diversionary technique (pre-adjudication) and at a (post-adjudication) pre-sentencing stage. In addition this type of model is now being applied in a voluntary way but on a small scale with adults. A significant feature of the FGC model is its greater use of community-based solutions with a consequent reduction in the number of young persons in state institutions.     

Drug-free workplace programmes: New Zealand perspective

New Zealand (NZ) companies have been introducing Drug & Alcohol Free Workplace Policies and Programmes, which include testing, since 1992. Most "safety-critical" industry sectors are now embracing drug and alcohol testing as part of comprehensive programmes which also have a strong focus on education and rehabilitation. Prison Inmate testing was also introduced in 1998. Lawful drug testing in NZ should be conducted to the strict medico-legal requirements of the Australian/New Zealand Standard, AS/NZS 4308:2001 "Procedures for the collection, detection and quantitation of drugs of abuse in urine." This paper gives an overview of the NZ experience, highlighting the mix of testing options employed, the industry sector trends, the categories of drugs misused, the influence of significant Employment Court Judgements, proposed changes to the AS/NZS 4308(2006), and current oral fluid research projects.     

The New Zealand Health and Disability Commissioner: a comparative assessment of the commissioner's contribution to protecting the rights of mental health consumers

The Health and Disabliity Commissioner's contribution to the protection of mental health consumers' rights is examined. This assessment covers a number of aspects. It includes the scope of consumer rights jurisdiction, the breadth of legal entitlements, protective mechanisms used, and the effectiveness of that protection. The Commissioner's role is also assessed comparatively. It is contrasted domestically with District Inspectors of Mental Health and internationally with Scottish and United Kingdom reform proposals. While analysis reveals considerable similarities, the New Zealand Health and Disability Commissioner is favourably highlighted in contrast with Scotland and the United Kingdom, particularly in the area of enforceability of mental health consumer rights.     

The highs and lows of working with sexual offenders: A New Zealand perspective

Abstract

The positive effects on clinicians responsible for the treatment of sexual offenders are little understood. The few available studies have focused upon the negative sequelae of this work. The current study of clinicians working therapeutically with sexual offenders at a community-based organization aimed for a more balanced picture of the effects of sex offender treatment provision. Using qualitative methods, both negative and positive aspects of this work emerged within three main themes: taking an optimistic perspective, working for community outcomes and supportive agency culture. Although the study revealed many challenges for therapists, these were found to be counterbalanced against rewards, affording a high degree of personal and professional fulfilment from working within this field.
