Forensic linguistics is at the cutting edge of the undercover policing of child sexual abuse on the open internet and dark web, and language and identity is a fundamental part of this. The authors have drawn on their extensive experience in training undercover officers to develop innovative methods in identifying the creation and performance of online personas, crucial in detecting identity disguise online. This groundbreaking book demonstrates these methods through case studies, whilst also exploring the link between language and identity. By bringing together previously opposed positions in forensic authorship analysis, the book develops a novel theory of linguistic identity, which will resonate not just in forensic authorship research but in sociolinguistics more widely. This unique forensic linguistic project has real-life impact in assisting the police in their investigation of online abusers, and has impact for students and researchers of linguistics, through its contribution to the research of linguistic identities.
The study of American Indian law and policy usually focuses on federal statutes and court decisions, with these sources forming the basis for most textbooks. Virtually ignored is the robust and growing body of scholarly literature analyzing and contextualizing these primary sources. Reading American Indian Law is designed to fill that void. Organized into four parts, this book presents 16 of the most impactful law review articles written during the last three decades. Collectively, these articles explore the core concepts underlying the field: the range of voices including those of tribal governments and tribal courts, the role property has played in federal Indian law, and the misunderstandings between both people and sovereigns that have shaped changes in the law. Structured with flexibility in mind, this book may be used in a wide variety of classroom settings including law schools, tribal colleges, and both graduate and undergraduate programs.
Previous researchers have examined the frequency at which healthy participants obtain one or more low scores on neuropsychological test batteries, proposing five psychometric principles of multivariate base rates: (a) low scores are common, with their frequency contingent on (b) the low score cutoff used, (c) the number of tests administered/interpreted, and (d) the demographic characteristics and (e) intelligence of participants. The current study explored whether these principles applied to high scores as well, using the Delis-Kaplan Executive Function System (D-KEFS).
Multivariate base rates of high scores (≥75th, ≥84th, ≥91st, ≥95th, and ≥98th percentiles) were derived for a three-test, four-test, and full D-KEFS battery, using the adult portion of the normative sample (aged 16–89 years; N = 1050) stratified by education and intelligence. The full D-KEFS battery provides 16 total achievement scores (primary indicators of executive function).
High scores occurred commonly for all batteries. For the three-test battery, 24.1% and 12.4% had 1 or more scores ≥95th percentile and ≥98th percentile, respectively. High scores occurred more often for longer batteries: 61.6%, 72.9%, and 87.8% obtained 1 or more scores ≥84th percentile for the three-test, four-test, and full batteries, respectively. The frequency of high scores increased with more education and higher intelligence.
The principles of multivariate base rates also applied to high D-KEFS scores: high scores were common and contingent on the cutoff used, number of tests administered/interpreted, and education/intelligence of examinees. Base rates of high scores may help clinicians identify true cognitive strengths and detect cognitive deficits in high functioning people.
Invasive species drive biodiversity loss and lead to changes in parasite–host associations. Parasites are linked to invasions and can mediate invasion success and outcomes. We review theoretical and empirical research into parasites in biological invasions, focusing on a freshwater invertebrate study system. We focus on the effects of parasitic infection on host traits (behaviour and life history) that can mediate native/invader trophic interactions. We review evidence from the field and laboratory of parasite-driven changes in predation, intraguild predation and cannibalism. Theoretical work shows that the trait-mediated effects of parasites can be as strong as classical density effects and their impact on the host’s trophic interactions merits more consideration. We also report on evidence of broader cascading effects warranting deeper study. Biological invasion can lead to altered parasite–host associations. Focusing on amphipod invasions, we find patterns of parasite introduction and loss that mirror host invasion pathways, but also highlight the risks of introducing invasive parasites. Horizon scanning and impact predictions are vital in identifying future disease risks, potential pathways of introduction and suitable management measures for mitigation.
The purpose of this study was to report the psychometric properties, in terms of validity and reliability, of the Unconscious Version of the Family Decision-Making Self-Efficacy Scale (FDMSE).
A convenience sample of 215 surrogate decision-makers for critically ill patients undergoing mechanical ventilation was recruited from four intensive care units at a tertiary hospital. Cross-sectional data were collected from participants between days 3 and 7 of a decisionally impaired patient's exposure to acute mechanical ventilation. Participants completed a self-report demographic form and subjective measures of family decision-making self-efficacy, preparation for decision-making, and decisional fatigue. Exploratory factor analyses, correlation coefficients, and internal consistency reliability estimates were computed to evaluate the FDMSE's validity and reliability in surrogate decision-makers of critically ill patients.
The exploratory factor analyses revealed a two-factor, 11-item version of the FDMSE was the most parsimonious in this sample. Furthermore, modified 11-item FDMSE demonstrated discriminant validity with the measures of fatigue and preparation for decision-making and demonstrated acceptable internal consistency reliability estimates.
Significance of results
This is the first known study to provide evidence for a two-factor structure for a modified, 11-item FDMSE. These dimensions represent treatment and palliation-related domains of family decision-making self-efficacy. The modified FDMSE is a valid and reliable instrument that can be used to measure family decision-making self-efficacy among surrogate decision-makers of the critically ill.
Compulsivity can be seen across various mental health conditions and refers to a tendency toward repetitive habitual acts that are persistent and functionally impairing. Compulsivity involves dysfunctional reward-related circuitry and is thought to be significantly heritable. Despite this, its measurement from a transdiagnostic perspective has received only scant research attention. Here we examine both the psychometric properties of a recently developed compulsivity scale, as well as its relationship with compulsive symptoms, familial risk, and reward-related attentional capture.
Two-hundred and sixty individuals participated in the study (mean age = 36.0 [SD = 10.8] years; 60.0% male) and completed the Cambridge-Chicago Compulsivity Trait Scale (CHI-T), along with measures of psychiatric symptoms and family history thereof. Participants also completed a task designed to measure reward-related attentional capture (n = 177).
CHI-T total scores had a normal distribution and acceptable Cronbach’s alpha (0.84). CHI-T total scores correlated significantly and positively (all p < 0.05, Bonferroni corrected) with Problematic Usage of the Internet, disordered gambling, obsessive-compulsive symptoms, alcohol misuse, and disordered eating. The scale was correlated significantly with history of addiction and obsessive-compulsive related disorders in first-degree relatives of participants and greater reward-related attentional capture.
These findings suggest that the CHI-T is suitable for use in online studies and constitutes a transdiagnostic marker for a range of compulsive symptoms, their familial loading, and related cognitive markers. Future work should more extensively investigate the scale in normative and clinical cohorts, and the role of value-modulated attentional capture across compulsive disorders.
According to the United States Eye Injury Registry, eye injury is the leading cause of monocular blindness, and there are approximately 2.4 million eye injuries occurring annually in the US, resulting in 500,000 years of lost eyesight annually.1 These injuries occur more often in males (>70%), and 95% of occupational injuries occur in males.2,3 This chapter will describe the approach to the patient with eye trauma in the emergency department (ED), including how to perform a detailed history and physical examination related to eye injuries, as well as covering the traumatic presentations in Table 9.1.
Psychosis is more prevalent among people in prison compared with the community. Early detection is important to optimise health and justice outcomes; for some, this may be the first time they have been clinically assessed.
Determine factors associated with a first diagnosis of psychosis in prison and describe time to diagnosis from entry into prison.
This retrospective cohort study describes individuals identified for the first time with psychosis in New South Wales (NSW) prisons (2006–2012). Logistic regression was used to identify factors associated with a first diagnosis of psychosis. Cox regression was used to describe time to diagnosis from entry into prison.
Of the 38 489 diagnosed with psychosis for the first time, 1.7% (n = 659) occurred in prison. Factors associated with an increased likelihood of being diagnosed in prison (versus community) were: male gender (odds ratio (OR) = 2.27, 95% CI 1.79–2.89), Aboriginality (OR = 1.81, 95% CI 1.49–2.19), older age (OR = 1.70, 95% CI 1.37–2.11 for 25–34 years and OR = 1.63, 95% CI 1.29–2.06 for 35–44 years) and disadvantaged socioeconomic area (OR = 4.41, 95% CI 3.42–5.69). Eight out of ten were diagnosed within 3 months of reception.
Among those diagnosed with psychosis for the first time, only a small number were identified during incarceration with most identified in the first 3 months following imprisonment. This suggests good screening processes are in place in NSW prisons for detecting those with serious mental illness. It is important these individuals receive appropriate care in prison, have the opportunity to have matters reheard and possibly diverted into treatment, and are subsequently connected to community mental health services on release.
This study investigates the pressure–strain tensor (
) in Langmuir turbulence. The pressure–strain tensor is determined from large-eddy simulations (LES), and is partitioned into components associated with the mean current shear (rapid), the Stokes shear and the turbulent–turbulent (slow) interactions. The rapid component can be parameterized using existing closure models, although the coefficients in the closure models are particular to Langmuir turbulence. A closure model for the Stokes component is proposed, and it is shown to agree with results from the LES. The slow component of
does not agree with existing ‘return-to-isotropy’ closure models for five of the six components of the Reynolds stress tensor, and a new closure model is proposed that accounts for these deviations which vary systematically with Langmuir number,
, and depth. The implications of these results for second- and first-order closures of Langmuir turbulence are discussed.
Frascati international research criteria for HIV-associated neurocognitive disorders (HAND) are controversial; some investigators have argued that Frascati criteria are too liberal, resulting in a high false positive rate. Meyer et al. recommended more conservative revisions to HAND criteria, including exploring other commonly used methodologies for neurocognitive impairment (NCI) in HIV including the global deficit score (GDS). This study compares NCI classifications by Frascati, Meyer, and GDS methods, in relation to neuroimaging markers of brain integrity in HIV.
Two hundred forty-one people living with HIV (PLWH) without current substance use disorder or severe (confounding) comorbid conditions underwent comprehensive neurocognitive testing and brain structural magnetic resonance imaging and magnetic resonance spectroscopy. Participants were classified using Frascati criteria versus Meyer criteria: concordant unimpaired [Frascati(Un)/Meyer(Un)], concordant impaired [Frascati(Imp)/Meyer(Imp)], or discordant [Frascati(Imp)/Meyer(Un)] which were impaired via Frascati criteria but unimpaired via Meyer criteria. To investigate the GDS versus Meyer criteria, the same groupings were utilized using GDS criteria instead of Frascati criteria.
When examining Frascati versus Meyer criteria, discordant Frascati(Imp)/Meyer(Un) individuals had less cortical gray matter, greater sulcal cerebrospinal fluid volume, and greater evidence of neuroinflammation (i.e., choline) than concordant Frascati(Un)/Meyer(Un) individuals. GDS versus Meyer comparisons indicated that discordant GDS(Imp)/Meyer(Un) individuals had less cortical gray matter and lower levels of energy metabolism (i.e., creatine) than concordant GDS(Un)/Meyer(Un) individuals. In both sets of analyses, the discordant group did not differ from the concordant impaired group on any neuroimaging measure.
The Meyer criteria failed to capture a substantial portion of PLWH with brain abnormalities. These findings support continued use of Frascati or GDS criteria to detect HIV-associated CNS dysfunction.
Over the course of the sixteenth century, Europeans writing about the ius gentium went from treating indigenous American rulers as the juridical equals of Europe's princes to depicting them as little more than savage brutes, incapable of bearing dominium and ineligible for the protections of the law of peoples. This essay examines the writings of Francisco de Vitoria and Alberico Gentili to show how this transformation in European perceptions of Native Americans resulted from fundamental changes in European society. The emergence of a novel conception of sovereignty amid the upheavals of the Protestant Reformation was central to this shift and provided a new foundation for Europe's continued imperial expansion into the Americas.
Schizotypy, a putative schizophrenia endophenotype, has been associated with brain-structural variations partly overlapping with those in psychotic disorders. Variations in precuneus structure have been repeatedly reported, whereas the involvement of fronto-striatal networks – as in schizophrenia – is less clear. While shared genetic architecture is thought to increase vulnerability to environmental insults, beneficial factors like general intelligence might buffer their effect.
To further investigate the role of fronto-striatal networks in schizotypy, we examined the relationship of voxel- and surface-based brain morphometry and a measure of schizotypal traits (Schizotypal Personality Questionnaire, with subscores Cognitive-Perceptual, Interpersonal, Disorganised) in 115 healthy participants [54 female, mean age (s.d.) = 27.57(8.02)]. We tested intelligence (MWT-B) as a potential moderator.
We found a positive association of SPQ Cognitive-Perceptual with putamen volume (p = 0.040, FWE peak level-corrected), moderated by intelligence: with increasing IQ, the correlation of SPQ Cognitive-Perceptual and striatal volume decreased (p = 0.022). SPQ Disorganised was positively correlated with precentral volume (p = 0.013, FWE peak level-corrected). In an exploratory analysis (p < 0.001, uncorrected), SPQ total score was positively associated with gyrification in the precuneus and postcentral gyrus, and SPQ Disorganised was negatively associated with gyrification in the inferior frontal gyrus.
Our findings support the role of fronto-striatal networks for schizotypal features in healthy individuals, and suggest that these are influenced by buffering factors like intelligence. We conclude that protective factors, like general cognitive capacity, might attenuate the psychosis risk associated with schizotypy. These results endorse the idea of a continuous nature of schizotypy, mirroring similar findings in schizophrenia.
At the conclusion of 2018, the future of the family law system in Australia was in a state of uncertainty, awaiting the outcome of a number of reforms ranging from Bills before Parliament to a wide-ranging review by the Australian Law Reform Commission. It seems unlikely that a radical overhaul or significant systemic change will result. Rather, the family law system will experience a continuation of incremental adjustments that have been occurring for many years. Thus, the theme that emerges in Australia for 2018 is that overwhelming complexity driven by incremental reforms continues, rather than any overall recasting of the law or underlying systems. In short, this is a time when there are many reformers but insufficient generalised reform.
In this chapter, the complexities of Australia's legal ‘pathway’ for the determination of parenting cases is first examined, together with some recent clarifications from the courts. It will be argued that the ‘pathway’ has reached a level of complexity that places it beyond the understanding of all but the most experienced family lawyers. It therefore also seems to impede movement toward litigation alternatives.
By way of an update, a summary of the two most significant specific reforms that have taken place in 2018 will be provided to demonstrate the wide array of reforms that continue to be pursued.
It is argued that whilst there has been much reform, the complexities of family law, and particularly the Australian legislation, are an under-acknowledged impediment to a functional family law system.
THE PROBLEM OF COMPLEXITY IN PARENTING LAWS
Like many legal systems, Australia's parenting provisions rest upon the fundamental concept of the ‘best interests’ of the child. This is expressed in the legislation as the ‘paramount consideration’. When Australia's Family Law Act commenced in 1975, the whole of the Part dealing with parenting was less than 2,700 words long. The key concept was then expressed in short compass:
64. (1) In proceedings with respect to the custody or guardianship of, or access to, a child of a marriage-
(a) the court shall regard the welfare of the child as the paramount consideration;
This chapter turns to Propertius and Philip Sidney and, taking its cue from from Cynthia as the eroticised muse of Propertian poetry, and the scornful muse of Astrophil and Stella 1, explores metaliterary themes of poetic practice. Reading the muse as a figure for ideas of inspiration and creativity, for authority and canonicity, we consider how the selected texts negotiate, articulate and configure ideas about the nature, identity and cultural function of poetry in Augustan Rome and Elizabethan England.
This introductory chapter sets out the terms of engagement for what follows: it defines Latin erotic elegy and its chaste rewriting by Petrarch; and it problematises Thomas Greene’s influential analysis of Renaissance imitatio. It establishes the broad research questions considered throughout this study and discusses the previous literature from which this book has developed. Two sub-sections engage with the theoretical interventions this project makes in terms of dialogic reception methodology and in reading problematically ‘lascivious’ verse. The first reconfigures Greene’s narrative of cultural loss as something more positive as borne out by the texts under consideration, and also discusses the question of what allows us to connect one text with another. The second sub-section explores the term ‘erotic’ as applied to the poetry read in this book, its problematic relationships to literary morality and pornography, and asks what the cultural potential of the erotic might be in each historical period under review.
