The study compared the predictive accuracy of three sex offender risk-assessment measures: the RRASOR (Hanson, 1997), Thornton's SACJ-Min (Grubin, 1998), and a new scale, Static-99, created by combining the items from the RRASOR and SACJ-Min. Predictive accuracy was tested using four diverse datasets drawn from Canada and the United Kingdom (total n = 1301). The RRASOR and the SACJ-Min showed roughly equivalent predictive accuracy, and the combination of the two scales was more accurate than either original scale. Static-99 showed moderate predictive accuracy for both sexual recidivism (r = 0.33, ROC area = 0.71) and violent (including sexual) recidivism (r = 0.32, ROC area = 0.69). The variation in the predictive accuracy of Static-99 across the four samples was no more than would be expected by chance.

Nanostructured materials may be defined as those materials whose structural elements - clusters, crystallites or molecules - have dimensions in the 1 to 100 nm range. The explosion in both academic and industrial interest in these materials over the past decade arises from the remarkable variations in fundamental electrical, optical and magnetic properties that occur as one progresses from an `infinitely extended' solid to a particle of material consisting of a countable number of atoms. This review details recent advances in the synthesis and investigation of functional nanostructured materials, focusing on the novel size-dependent physics and chemistry that results when electrons are confined within nanoscale semiconductor and metal clusters and colloids. Carbon-based nanomaterials and nanostructures including fullerenes and nanotubes play an increasingly pervasive role in nanoscale science and technology and are thus described in some depth. Current nanodevice fabrication methods and the future prospects for nanostructured materials and nanodevices are discussed.

Its controversial past notwithstanding, psychopathy has emerged as one of the most important clinical constructs in the criminal justice and mental health systems. One reason for the surge in theoretical and applied interest in the disorder is the development and widespread adoption of reliable and valid methods for its measurement. The Hare PCL-R provides researchers and clinicians with a common metric for the assessment of psychopathy, and has led to a surge in replicable and meaningful findings relevant to the issue of risk for recidivism and violence, among other things. Most of the research thus far has been based on North American samples of offenders and forensic psychiatric patients. We summarize this research and compare it with findings from several other countries, including England and Sweden. We conclude that the ability of the PCL-R to predict recidivism, violence, and treatment outcome has considerable cross-cultural generalizability, and that the PCL-R and its derivatives play a major role in the understanding and prediction of crime and violence.

In this study, we investigated the psychophysiological responsiveness of psychopathic individuals to distress cues and to threatening and neutral stimuli. Eighteen psychopathic individuals and 18 incarcerated control individuals, identified using the Revised Psychopathy Checklist (Hare, 1991, The Hare Psychopathy Checklist-Revised, Toronto: Multi-Health Systems), were shown slides of these three types of stimuli, and their electrodermal responses were recorded. The psychopathic individuals showed (relative to the controls) reduced electrodermal responses to the distress cues. In contrast, the two groups did not differ in their electrodermal responses to the threatening stimuli and to the neutral stimuli. The results are interpreted within the Violence Inhibition Mechanism model (Blair, 1995, Cognition, 57, 1-29) of the psychopathic individual.

Abstract Measurement of the likely magnitude of the economic impact of climate change on African agriculture has been a challenge. Using data from a survey of more than 9,000 farmers across 11 African countries, a cross-sectional approach estimates how farm net revenues are affected by climate change compared with current mean temperature. Revenues fall with warming for dryland crops (temperature elasticity of −1.9) and livestock (−5.4), whereas revenues rise for irrigated crops (elasticity of 0.5), which are located in relatively cool parts of Africa and are buffered by irrigation from the effects of warming. At first, warming has little net aggregate effect as the gains for irrigated crops offset the losses for dryland crops and livestock. Warming, however, will likely reduce dryland farm income immedia-tely. The final effects will also depend on changes in precipitation, because revenues from all farm types increase with precipitation. Because irrigated farms are less sensitive to climate, where water is available, irrigation is a practical adaptation to climate change in Africa.

This paper describes the construction and testing of a framework for dynamic risk assessment. A review of previous studies identified 4 domains into which dynamic risk factors for sexual offending seem to fall. These were sexual interests, distorted attitudes, socioaffective functioning, and self-management. Psychometric indicators for 3 of the domains were identified, and 2 studies are reported using these indicators to test the framework. Study 1 divided men serving a prison sentence for a sexual offense against a child into 2 groups--those with a previous conviction of this kind (Repeaters) and those for whom this was the only time they had been sentenced for such an offense (Current Only). The Repeaters were found to show more distorted attitudes, worse socioaffective functioning, and poorer self-management than did the Current Only group. Study 2 used a simple algorithm to combine these psychometric indicators into an overall "Deviance" classification. Reconviction data was obtained for offenders classified as high, moderate, or low on Deviance. Sexual reconviction was found to be monotonically associated with the Deviance classification. Logistic regression analysis showed that both static variables (Static-99) and the Deviance classification made independent contributions to prediction. It is suggested that risk assessment procedures should combine these 2 approaches.

The notion of ‘cognitive distortion’ has become enshrined in the offender treatment literature over the last 20 years, yet the concept still suffers from a lack of definitional clarity. In particular, the umbrella term is often used to refer to offence‐supportive attitudes, cognitive processing during an offence sequence, as well as post‐hoc neutralisations or excuses for offending. Of these very different processes, the last one might be the most popular and problematic. Treatment programmes for offenders often aim to eliminate excuse‐making as a primary aim, and decision‐makers place great weight on the degree to which an offender “takes responsibility” for his or her offending. Yet, the relationship between these after‐the‐fact explanations and future crime is not at all clear. Indeed, the designation of post hoc excuses as criminogenic may itself be an example of fallacious thinking. After all, outside of the criminal context, post hoc excuse‐making is widely viewed as normal, healthy, and socially rewarded behaviour. We argue that the open exploration of contextual risk factors leading to offending can help in the identification of criminogenic factors as well as strengthen the therapeutic experience. Rather than insist that offenders take “responsibility” for the past, we suggest that efforts should focus on helping them take responsibility for the future, shifting the therapeutic focus from post hoc excuses to offence‐supportive attitudes and underlying cognitive schemas that are empirically linked to re‐offending.

Accounts of prison life consistently describe a culture of mutual mistrust, fear, aggression and barely submerged violence. Often too, they explain how prisoners adapt to this environment—in men’s prisons, at least—by putting on emotional ‘masks’ or ‘fronts’ of masculine bravado which hide their vulnerabilities and deter the aggression of their peers. This article does not contest the truth of such descriptions, but argues that they provide a partial account of the prison’s emotional world. Most importantly, for current purposes, they fail to describe the way in which prisons have a distinctive kind of emotional geography, with zones in which certain kinds of emotional feelings and displays are more or less acceptable. In this article, we argue that these ‘emotion zones’, which cannot be characterized either as ‘frontstage’ or ‘backstage’ domains, enable the display of a wider range of feelings than elsewhere in the prison. Their existence represents a challenge to depictions of prisons as environments that are unwaveringly sterile, unfailingly aggressive or emotionally undifferentiated.

A two-dimensional risk assessment system for sexual offenders was created that can classify them for risk of sexual recidivism, risk of nonsexual violent recidivism, and the composite risk of reconviction for sexual or nonsexual assaults. Receiver operating characteristic (ROC) analyses of separate follow-up samples were used for cross-validation. The system is easier to score than Static-99, and substantially easier to score than the VRAG or SORAG, while yielding comparable predictive accuracy in cross-validation samples with follow-ups from 2 years to 19 years. ROC AUC coefficients between.74 and.81 were found for the different scales and samples.

Environmental context It is now nearly 20 years since the introduction of the technique of diffusive gradients in thin films, which can provide information on solute concentrations and dynamics in sediments, soils and water. The interpretation of these measurements in terms of concentrations relies on simple equations and associated assumptions. This review examines how well they have stood the test of time. Abstract Diffusive gradients in thin films (DGT) is now widely used to measure a range of determinands in waters, soils and sediments. In most cases the mass accumulated is interpreted in terms of a labile form of the component being measured using a simple equation that applies to steady-state conditions. During the past decade several publications have revealed phenomena that question some of the assumptions necessary for use of the simple equation. This review systematically examines the available evidence relating to appropriate geometry, possible charge effects, binding of solutes and ligands to the diffusive gel and filter, the rate of reaction with the binding layer, the effects of solution complexation and kinetic limitation, necessary time for deployment and the measurement of nanoparticles. DGT emerges as a robust monitoring tool for labile components in solution. Although there is evidence, for some conditions, of binding of metals and, more moderately, humic substances to the diffusive gel and filter membrane, this is unlikely to affect DGT measurement in natural waters for deployment times exceeding a few days. Detailed speciation and kinetic studies require a more thorough interpretation of the mass accumulated by DGT. A coherent theory has emerged for relatively simple solutions, but systems with complex heterogeneous ligands, as is the case for natural waters, are challenging. The size discrimination of DGT is still poorly known. Systematic measurements with well characterised nanoparticles are required to define the distribution of pore sizes in the gels and to establish the contribution of natural colloids to the DGT measurement.

Abstract This paper investigates the Theory of Mind ability of psychopaths. Happé's (1994) advanced test of Theory of Mind was presented to 25 psychopaths and 25 non-psychopathic incarcerated controls. The psychopaths and the non-psychopathic controls did not differ in their performance on this task. However, the psychopaths were performing significantly better than Happé's most highly able adult autistic population. It was therefore concluded that the psychopath does not have a Theory of Mind deficit. Speculations are made about the different developmental pathways of autism and psychopathy and the differences in the empathy deficit present in both these disorders.

This study examined how well historical information and psychometric data predicted sexual recidivism in a sample of child abusers about to undergo group-based cognitive behavioral treatment in the community. Static, historical factors, as measured by the Static-99 (R. K. Hanson & D. Thornton, 2000), significantly predicted recidivism over the 6-year follow-up period. High-risk men were over 5 times more likely to be reconvicted for a sexual offence compared to low-risk men. Adding psychometric measures of dynamic risk (e.g., pro-offending attitudes, socio-affective problems) significantly increased the accuracy of risk prediction beyond the level achieved by the actuarial assessment of static factors. This result indicates the importance of considering dynamic risk factors in any comprehensive risk protocol.

Abstract Purpose – Ostensibly, less than 10 per cent of UK organisations accomplish successful lean implementations. A refined system to the one offered by the balanced scorecard is needed. The purpose of this paper is to propose a robust system that not only focuses on the intangible and intellectual assets but also embraces various time horizons and the interests of multiple stakeholders. Design/methodology/approach – The dynamic multi‐dimensional performance (DMP) framework has been adapted which enables organisations to successfully gauge, in a holistic approach, whether lean has in fact proven successful in their respective organisations. Findings – The DMP framework embracing five dimension proves to be more robust than its predecessors and stresses the need to utilise a smaller set of multidimensional metrics which are closely aligned to an organisation's strategies. Research limitations/implications – Intangible assets have become the major source for competitive advantage. Tangible assets accounted for a book value of less than 20 per cent of companies' market values in 2000. Organisations need to promote a portfolio of measures directed at both the internal and external environments. Practical implications – Despite the popularity of the balanced scorecard, it has recently proven inadequate in certain circumstances. The proposal enables managers to bridge the gap between the real and aspired performance. Originality/value – The DMP model presented in this paper has generic appeal and can be applied to quite disparate organisations. It provides a good barometer for multiple time horizons and facilitates the examination of a wider view of organisational success.

The present study examined the relationship between reliably identified therapist characteristics and treatment-induced changes in sexual offender treatment programmes in English prisons. The results indicated that 10 therapist features predicted beneficial changes in coping skills, perspective-taking, and relationship difficulties. A confrontational style, on the other hand, was negatively related to increased competence in coping. The results are discussed in terms of their research and clinical implications.

Electron transport system (ETS) function in mitochondria is essential for the aerobic production of energy. Because ETS function requires extensive interactions between mitochondrial and nuclear gene products, coadaptation between mitochondrial and nuclear genomes may evolve within populations. Hybridization between allopatric populations may then expose functional incompatibilities between genomes that have not coevolved. The intertidal copepod Tigriopus californicus has high levels of nucleotide divergence among populations at mitochondrial loci and suffers F2 hybrid breakdown in interpopulation hybrids. We hypothesize that hybridization results in incompatibilities among subunits in ETS enzyme complexes and that these incompatibilities result in diminished mitochondrial function and fitness. To test this hypothesis, we measured fitness, mitochondrial function, and ETS enzyme activity in inbred recombinant hybrid lines of Tigriopus californicus. We found that (1) both fitness and mitochondrial function are reduced in hybrid lines, (2) only those ETS enzymes with both nuclear and mitochondrial subunits show a loss of activity in hybrid lines, and (3) positive relationships exist between ETS enzyme activity and mitochondrial function and between mitochondrial function and fitness. We also present evidence that hybrid lines harboring mitochondrial DNA (mtDNA) and mitochondrial RNA polymerase (mtRPOL) from the same parental source population have higher fitness than those with mtDNA and mtRPOL from different populations, suggesting that mitochondrial gene regulation may play a role in disruption of mitochondrial performance and fitness of hybrids. These results suggest that disruption of coadaptation between nuclear and mitochondrial genes contributes to the phenomenon of hybrid breakdown.

The processing of emotional expressions is fundamental for normal socialization and interaction. Reduced responsiveness to the expressions of sadness and fear has been implicated in the development of psychopathy (R. J. R. Blair, 1995). The current study investigates the ability of adult psychopathic individuals to process vocal affect. Psychopathic and nonpsychopathic adults, defined by the Hare Psychopathy Checklist-Revised (PCL-R; R. D. Hare, 1991), were presented with neutral words spoken with intonations conveying happiness, disgust, anger, sadness, and fear and were asked to identify the emotion of the speaker on the basis of prosody. The results indicated that psychopathic inmates were particularly impaired in the recognition of fearful vocal affect. These results are interpreted with reference to the low-fear and violence inhibition mechanism models of psychopathy.

BACKGROUND: Suicidal behaviour and completed suicide are serious problems within British prisons, leading to significant morbidity and mortality, and are the focus of major efforts towards their prevention. AIM: To explore the demographic, social and psychiatric correlates of suicidal behaviour in prisons in England and Wales and their relationship with health service use; and to develop a combined psychosocial model of risk. METHOD: This report analyses the prevalence of suicidal ideation and suicide attempts in the ONS National Prison Survey, and their association with the presence of psychiatric disorders, personality disorder, substance abuse and social risk factors. These data were compared with data from the second national survey of psychiatric morbidity in adults living at home. In both surveys, a two-phase interviewing procedure was used, covering general health, health service use, assessment of psychiatric disorders, life events, social supports, suicidal behaviour, activities of daily living, sociodemographic data, substance abuse and intelligence. RESULTS: Suicidal thoughts and suicide attempts were commoner in prisons than in the general population and these were significantly associated with higher rates of psychosis, neurosis and personality disorder in prisons. In addition, demographic and factors such as being young, single, white, leaving school early and experiencing poor social support and significant social adversity were important risk factors for suicidal thoughts. Crucially, there was no separate category of people at suicidal risk who did not have psychiatric disorders. CONCLUSIONS: The high rates of suicidal behaviour in prisons cannot be addressed without adequate attention to the high rates of psychiatric disorder and vulnerability factors in prisoners.

Treatment efficacy is described for a sample of sexual offenders who had undertaken treatment in United Kingdom prisons (N = 647) and for a retrospectively selected comparison group (N = 1,910). The outcomes under observation in this study were sexual, sexual and/or violent, and general reconviction. Treatment impact was also examined in relation to offenders' risk of reconviction. The treatment group had slightly lower 2-year sexual reconviction rates than the comparison group, but these differences were not statistically significant. Significant differences were found between the treatment and comparison group for sexual and/or violent reconviction. Further analysis suggested that treatment produced a reduction in the probability of sexual and/or violent reconviction (p <.05) when other relevant variables were controlled for. General reconviction rates were consistently lower in the treatment group, but these differences were not significant.

CONTEXT: Adrenal crisis is a life-threatening event that occurs regularly in Addison's patients receiving standard replacement therapy. Patient reports suggest that it is an underestimated and under-managed event. OBJECTIVE: To assess the frequency of adrenal crisis in diagnosed patients and to understand the factors contributing to the risks of adrenal crisis. DESIGN: We conducted a postal survey of Addison's patients in four countries, UK (n=485), Canada (n=148), Australia (n=123) and New Zealand (n=85) in 2003, asking about patients' experiences of adrenal crisis and their demographic characteristics. In 2006, a shorter follow-up survey was conducted in the UK (n=261). METHOD: The frequency and causes of adrenal crisis were compared across both surveys. Demographic data from the 2003 survey were analysed to establish the main variables associated with an elevated risk of crisis. RESULTS: Around 8% of diagnosed cases can be expected to need hospital treatment for adrenal crisis annually. Exposure to gastric infection is the single most important factor predicting the likelihood of adrenal crisis. Concomitant diabetes and/or asthma increase the frequency of adrenal crises reported by patients. CONCLUSION: The endocrinologist has a responsibility to ensure that Addison's patients have adequate access to life-saving emergency injection materials and repeated, practical training sessions in how to use them, while the general practitioner plays a vital role as in arranging prompt emergency admissions.
