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.     

Mismatch distribution analysis of Y-STR haplotypes as a tool for the evaluation of identity-by-state proportions and significance of matches--the European picture

We suggest the use of the mismatch distribution methodology as an easy way to estimate the distance between all pairs of haplotypes present in a sample. This approach allows the evaluation of the proportion of pairs of Y-STR haplotypes that are prone to become identical by state (IBS), in one generation, by recurrent mutation, a statistic of major importance in the forensic field. The mismatch approach presents some advantages alternatively to the empirical one, since it is not necessary to have simultaneous information on STRs and SNPs, and it allows the evaluation of IBS also within-haplogroups. The estimation of IBS at an European scale showed that there is a high population substructuring for this parameter, increasing from southern-central European countries towards west and north, in accordance to what was found for Y-biallelic markers. This result seems to imply a more careful use of large databases for matching evaluation, even in the absence of population structure for general Y-STR diversity. Furthermore, mismatch distribution can be used to measure the distance between a particular haplotype and all the haplotypes in a sample. When applied to the most frequent haplotypes in Europe it revealed that the opportunity for IBS is not directly related to the frequency of a haplotype, but highly dependent on the proportion of neighbouring haplotypes--so, that reporting on the haplotype frequency for evaluating the significance of a match can be misleading.     

Y-chromosome STR haplotypes and alleles in the ethnic group of Polish Tatars residing in the Northeastern Poland

Haplotype and allele frequencies for eight Y-STRs were determined in a population sample of the ethnic group of Polish Tatars residing in the Northeastern Poland. A total of 125 unrelated males produced 101 different haplotypes. Thirteen haplotypes occurred more than once, while 88 haplotypes were unique. The observed gene diversity was 0.9638. The ethnic group of Polish Tatars can be distinguished from the autochthonous Poles based on AMOVA estimates in all the analyzed systems except DYS385.     

Allele frequencies of sixteen STRs in the population of Northern Portugal

Allele frequencies of sixteen autossomal short tandem repeats (STRs), D3S1358, VWA, D16S539, D8S1179, D21S11, D18S51, TH01, FGA, D5S818, D13S317, D7S820, TPOX, CSF1PO, Penta D, Penta E (included in the PowerPlex 16 kit), and the SE33 (PowerPlex ES Monoplex System SE33) were determined in a sample of 200 healthy unrelated individuals from the north of Portugal.     

Matricide by person with bipolar disorder and dependent overcompliant personality

Matricide is an infrequent form of homicide. This paper is to present a case of matricide with typical characteristics of the act but interesting particularities as well. The perpetrator was a 43-year-old man, respected member of his community, with over compliant characteristics, eagerness in serving people and caring his parents, good social adaptation before and after the crime. He abandoned his family and work in order to better serve his old, disabled but over demanding mother who frequently insulted and humiliated him. Suddenly he came to a state of "mental confusion" and strangled her. After the crime, the perpetrator manifested the symptoms of a bipolar disorder and also received the diagnosis of dependant personality disorder. Years later, he presented again a crisis of escalating aggressive urge for which he was hospitalized. Many people and associations of his hometown actively demanded the minimal possible punishment for him. The case is discussed especially concerning: a) hypotheses about the aetiopathogeny of the act, b) the constant support provided to the perpetrator by his family and social environment.     

Immunocytochemical examinations of biological traces on expanding bullets (QD-PEP)

When a crime victim has been injured with several different objects, it is of central importance for the forensic investigation to be able to show which object caused which injury, especially if one of the injuries was lethal. In cases of bullet penetration wounds it is often not possible to find such evidence. However, immunocytochemical investigations can accurately match a victim's injury to a particular bullet path through the body. In cases where expanding bullets have been used and the heart or liver has been struck by a projectile, it can be shown that the cells remaining on the bullet stem from those particular organs. In this case the specific cytological evidence was established by means of marking heart- and liver-specific tissue proteins with appropriate antibodies (cardiac troponin I and HepPar 1) followed by disclosure with an appropriate chromogen. Thus, in principle, cells can be used as evidence after being extracted from the projectiles by either damp cotton-wool swabs or adhesive trace evidence tape. Because of the specificity of the used immunocytochemical antibodies, finding evidence of an antigen on a particular projectile proves that it was the object that injured the organs.
