Can the mana of Maori men who sexually abuse children be restored?

The problem of child sex abuse is prevalent across all segments of society, and Maori, unfortunately, are overrepresented in this problem. In the total prison population of 6591, 13.6% are identified as child sex offenders. Of the 3,299 Maori in prison 283 (8.5%) are identified as child sex offenders whereas 631 (18.6%) of the 3292 non-Maori have been so identified. However, Maori only represent approximately 15% of the general population. In proportionate terms, approximately one of every 970 Maori men is currently in prison for child sex offences, while for non-Maori that figure is one in 31251. Also, disclosures from offenders suggest that sexual abuse is particularly common in rural or disadvantaged areas, with offenders frequently reporting being abused by multiple offenders and being aware of chronic abuse, little of which was ever reported

An evaluation of the use of phallometric assessment for men incarcerated for sexually offending against children in New Zealand: Past results and future directions.

Phallometric assessment, the direct measurement of male sexual arousal in response to stimuli presented in a controlled setting, has been widely used in the assessment of sexual offenders to detect deviant sexual interests, determine treatment needs and inform risk assessments, but they have also been criticised due to a weak theoretical basis, wide variations in methodology and serious concerns around reliability and validity. From 1999 to 2007, phallometric assessments were conducted at two treatment units for incarcerated child sex offenders in New Zealand using a standardised Monarch 3.1 phallometric system which provided a database of 583 cases for analysis. This project, the only large scale analysis of phallometric data known to have been conducted using New Zealand data, was designed to explore a large number of research questions in three areas. The first area explored the factor structure of the assessments and the relationships between arousal profiles and a variety of co-existing demographic and offence related variables including age, social desirability, victim gender and victim age. The second area investigated the ability of a large number of possible phallometric indices to predict future both any sexual reconvictions and those involving children, with a particular focus on the role played by stimuli depicting teenagers. The third area investigated the prevalence and effects of the deliberate suppression of arousal, and analysed the ability of physiological measures to detect such suppression. The results of these investigations indicated that phallometric data factored according to the gender of the stimuli and could be further divided into age preferences resembling pedophila and teleiophilia. Phallometric indices consistently related to known victim gender but not victim age, suggesting that these offenders tended to target victims based on gender preferences but not age preferences to the same degree, posing questions about the relevance of diagnostic labels for age based sexual preferences. Phallometric results were demonstrated to be predictive of sexual reoffending against children and outperformed actuarial or structured dynamic variables. The best predictions were obtained using ratio and z-scored differential deviance indices from initial assessments to predict sexual reconvictions involving children in a sample of extrafamilial offenders, with a maximum AUC found of .69. Post-treatment assessments also predicted reconviction, but change scores from pre to post-treatment did not, suggesting that the practice of conducting post-treatment phallometric assessments is of little value. The investigation into the suppression of arousal found that subjects could reduce the magnitude of their arousal, but could not reduce the discriminative abilities of interpretative indices. In this sample, there was no reliable way to detect markers of suppression using GSR traces, respiration traces or the patterns in the penile traces themselves. While many of these findings support those in the existing literature, others are original contributions which extend the literature, including the use of a Principal Component Analysis on raw phallometric data, an exploration of the effects of the use of pubescent stimuli, a mathematical rather than subjective analysis of the properties of penile, GSR and respiration data in relation to suppression, the use of Receiver Operating Characteristic analysis to clarify the relationship between arousal profiles and victim preferences and an analysis of the effects of varying significance levels on the detection of male victims and the prediction of recidivism. Overall, this research extends and clarifies the phallometric literature through evidence that phallometric assessments may not provide a definitive measure of sexual interests and are not an absolute predictor of reconviction, but are the best available tool for measuring arousal patterns and could be a valuable contributor to a multimodal assessment of risk

Satellite tracking of offenders and integrated offender management: a local case study

This article reports findings from an evaluation of a Global Positioning System (GPS) pilot that took place in the Cardiff Integrated Offender Management Unit (IOMU). The evaluation was based primarily upon qualitative interviews with about half of the tracked sample of offenders, plus interviews with key stakeholders from the IOMU, police and courts. The findings revealed a general consensus of positive views from both offenders and practitioners about the experience of GPS tracking. However, these generally positive outcomes were clearly related to the voluntary and relatively targeted nature of the pilot, which would be challenged if/when GPS tracking was introduced more widely

The role of BIM in tackling obsolescence, climate change, and sustainability

Although the BIM technology is applicable to both new and existing buildings, it is arguably more established in the former than the latter. This is despite the fact that, in the UK alone, 70–80% of what has been built by 2010, is estimated to continue to exist for a number of decades to come: including the years 2020 and 2050 (the two main temporal deadlines in the Climate Change Act, 2008). In addition, this existing building stock is subject to obsolescence (both climate change-induced and non-climate change-associated) which in turn compromises sustainability. Thus, there are three notions that appear to be interwoven, i.e. Obsolescence, Climate Change, and Sustainability: the question is whether BIM can be exploited to address these. There has been only limited research work to explore the possible influence of BIM upon obsolescence, climate change, and sustainability as individual issues,and none reported, to-date, in terms of an approach to their collective consideration. This paper conceptually explores how BIM can be related with all three crucial notions simultaneously as well as discretely. It is argued that such studies can be particularly valuable in the face of escalating pressures in terms of future obsolescence risks, overwhelming evidence of climate change, and escalating sustainability agendas. The paper reviews current work that relates state-of-the-art BIM to the three notions, both separately and collectively, and thereby delineates the potential for BIM to play a role in addressing the three issues simultaneously

Notes on distribution and behaviour of the Rufous-winged Sunbird Cinnyris rufipennis

Rufous-winged Sunbird Cinnyris rufipennis is known only from Udzungwa Mountains in central Tanzania where it occurs in nine montane forests. Based on field surveys between 2011 and 2014, supplemented by observations made by all authors since the early 1990s, we provide a map showing its distribution and relative abundance. We estimate the size of the core areas where Rufous-winged Sunbird is common to c. 120 km2 and the total range to about 200 km2. We also provide data that suggests that breeding takes place during the rainy season from November to February with the breeding area usually centred on a forest glade or tree-fall gap. Finally, we describe observations of presumed lekking courtship display with up to three males assembling in a clearing and excitedly hopping from branch to branch, singing aggressively at each other with a single female observing

The Juncaceae-Cyperaceae Interface: A Combined Plastid Sequence Analysis

Phylogenetic relationships of Juncaceae and related families of Cyperales were investigated using DNA sequence data from the plastid rps16 intron, trnL intron, and trnL–F intergenic spacer. Results using parsimony analysis of the aligned matrices find Juncaceae and Cyperaceae to be monophyletic families, which form a clade sister to a monophyletic Thurniaceae that includes Prionium (Prioniaceae), all three clades with 100% bootstrap support. Within Juncaceae, the genus Luzula is monophyletic with 100% bootstrap support and sister to the rest of Juncaceae. Further groupings within the family indicate that the genus Juncus may be monophyletic only with the inclusion of the single-flowered genera of Juncaceae (Distichia, Oxychloe, Marsippospermum, and Rostkovia; sequences of Patosia were not included). Major groupings within Juncus are supported by the morphological characters of septate or non-septate leaves and the presence or absence of bracts subtending the flowers, which have been used to define subgenera and sections within Juncus

A critique of general allometry-inspired models for estimating forest carbon density from airborne LiDAR.

There is currently much interest in developing general approaches for mapping forest aboveground carbon density using structural information contained in airborne LiDAR data. The most widely utilized model in tropical forests assumes that aboveground carbon density is a compound power function of top of canopy height (a metric easily derived from LiDAR), basal area and wood density. Here we derive the model in terms of the geometry of individual tree crowns within forest stands, showing how scaling exponents in the aboveground carbon density model arise from the height-diameter (H-D) and projected crown area-diameter (C-D) allometries of individual trees. We show that a power function relationship emerges when the C-D scaling exponent is close to 2, or when tree diameters follow a Weibull distribution (or other specific distributions) and are invariant across the landscape. In addition, basal area must be closely correlated with canopy height for the approach to work. The efficacy of the model was explored for a managed uneven-aged temperate forest in Ontario, Canada within which stands dominated by sugar maple (Acer saccharum Marsh.) and mixed stands were identified. A much poorer goodness-of-fit was obtained than previously reported for tropical forests (R2 = 0.29 vs. about 0.83). Explanations for the poor predictive power on the model include: (1) basal area was only weakly correlated with top canopy height; (2) tree size distributions varied considerably across the landscape; (3) the allometry exponents are affected by variation in species composition arising from timber management and soil conditions; and (4) the C-D allometric power function was far from 2 (1.28). We conclude that landscape heterogeneity in forest structure and tree allometry reduces the accuracy of general power-function models for predicting aboveground carbon density in managed forests. More studies in different forest types are needed to understand the situations in which power functions of LiDAR height are appropriate for modelling forest carbon stocks

The Imprint of Galaxy Formation on X-ray Clusters

It is widely believed that structure in the Universe evolves hierarchically, as primordial density fluctuations, amplified by gravity, collapse and merge to form progressively larger systems. The structure and evolution of X-ray clusters, however, seems at odds with this hierarchical scenario for structure formation. Poor clusters and groups, as well as most distant clusters detected to date, are substantially fainter than expected from the tight relations between luminosity, temperature and redshift predicted by these models. Here we show that these discrepancies arise because, near the centre, the entropy of the hot, diffuse intracluster medium (ICM) is higher tha$achievable through gravitational collapse, indicating substantial non-gravitational heating of the ICM. We estimate this excess entropy for the first time, and argue that it represents a relic of the energetic winds through which forming galaxies polluted the ICM with metals. Energetically, this is onl$ possible if the ICM is heated at modest redshift (z \ltsim 2) but prior to cluster collapse, indicating that the formation of galaxies precedes that of clusters and that most clusters have been assembled very recently.Comment: 5 pages, plus 2 postscript figures (one in colour), accepted for publication in Natur
