Are juveniles who have committed sexual offenses the same everywhere? psychometric properties of the juvenile sex offender assessment protocol–II in a portuguese youth sample

Over the last decade, we have witnessed consistent advances in risk assessment procedures, namely the validation of those used with juveniles who have committed sexual offenses. The adaptation of these instruments into other languages requires research examining the conceptual and metric equivalence of the instruments, not just translation equivalence. Informed by data from 141 boys, aged 13 to 18, the psychometric properties of the Portuguese version of the Juvenile Sex Offender Assessment Protocol–II (J-SOAP-II), regarding reliability and construct validation, are presented and discussed. Factor structure, internal consistency, and interrater reliability were examined, and a reliable factorial structure that was consistent with the original validation of the J-SOAP was found. Scales 2 and 3 had good internal consistency, and Scale 1 had acceptable internal consistency. Results regarding concurrent validity revealed mostly statistically significant correlations. The implications of this research for juvenile sex offender risk assessments are discussed.The author(s) received no financial support for the research, authorship, and/or publication of this article

At what time does a quantum experiment have a result?

This paper provides a general method for defining a generalized quantum observable (or POVM) that supplies properly normalized conditional probabilities for the time of occurrence (i.e., of detection). This method treats the time of occurrence as a probabilistic variable whose value is to be determined by experiment and predicted by the Born rule. This avoids the problematic assumption that a question about the time at which an event occurs must be answered through instantaneous measurements of a projector by an observer, common to both Rovelli (1998) and Oppenheim et al. (2000). I also address the interpretation of experiments purporting to demonstrate the quantum Zeno effect, used by Oppenheim et al. (2000) to justify an inherent uncertainty for measurements of times.Comment: To appear in proceedings of 2015 ETH Zurich Workshop on Time in Physic

The prevalence of common mental disorders and PTSD in the UK military: using data from a clinical interview-based study

<p>Abstract</p> <p>Background</p> <p>The mental health of the Armed Forces is an important issue of both academic and public interest. The aims of this study are to: a) assess the prevalence and risk factors for common mental disorders and post traumatic stress disorder (PTSD) symptoms, during the main fighting period of the Iraq War (TELIC 1) and later deployments to Iraq or elsewhere and enlistment status (regular or reserve), and b) compare the prevalence of depression, PTSD symptoms and suicidal ideation in regular and reserve UK Army personnel who deployed to Iraq with their US counterparts.</p> <p>Methods</p> <p>Participants were drawn from a large UK military health study using a standard two phase survey technique stratified by deployment status and engagement type. Participants undertook a structured telephone interview including the Patient Health Questionnaire (PHQ) and a short measure of PTSD (Primary Care PTSD, PC-PTSD). The response rate was 76% (821 participants).</p> <p>Results</p> <p>The weighted prevalence of common mental disorders and PTSD symptoms was 27.2% and 4.8%, respectively. The most common diagnoses were alcohol abuse (18.0%) and neurotic disorders (13.5%). There was no health effect of deploying for regular personnel, but an increased risk of PTSD for reservists who deployed to Iraq and other recent deployments compared to reservists who did not deploy. The prevalence of depression, PTSD symptoms and subjective poor health were similar between regular US and UK Iraq combatants.</p> <p>Conclusion</p> <p>The most common mental disorders in the UK military are alcohol abuse and neurotic disorders. The prevalence of PTSD symptoms remains low in the UK military, but reservists are at greater risk of psychiatric injury than regular personnel.</p

Chaos, containment and change: responding to persistent offending by young people

This article reviews policy developments in Scotland concerning 'persistent young offenders' and then describes the design of a study intended to assist a local planning group in developing its response. The key findings of a review of casefiles of young people involved in persistent offending are reported. It emerges that youth crime and young people involved in offending are more complex and heterogeneous than is sometimes assumed. This, along with a review of some literature about desistance from offending, reaffirms the need for properly individualised interventions. Studies of 'desisters' suggest the centrality of effective and engaging working relationships in this process. However, these studies also re-assert the significance of the social contexts of workers’ efforts to bring 'change' out of 'chaos'. We conclude therefore that the 'new correctionalism' must be tempered with appreciation of the social exclusion of young people who offend

Acute effects of a thermogenic nutritional supplement on cycling time to exhaustion and muscular strength in college-aged men

<p>Abstract</p> <p>Background</p> <p>The purpose of the present study was to examine the acute effects of a thermogenic nutritional supplement containing caffeine, capsaicin, bioperine, and niacin on muscular strength and endurance performance.</p> <p>Methods</p> <p>Twenty recreationally-active men (mean ± SD age = 21.5 ± 1.4 years; stature = 178.2 ± 6.3 cm; mass = 76.5 ± 9.9 kg; VO_{2 PEAK}= 3.05 ± 0.59 L/min^-1) volunteered to participate in this randomized, double-blinded, placebo-controlled, cross-over study. All testing took place over a three-week period, with each of the 3 laboratory visits separated by 7 days (± 2 hours). During the initial visit, a graded exercise test was performed on a Lode Corival cycle ergometer (Lode, Groningen, Netherlands) until exhaustion (increase of 25 W every 2 min) to determine the maximum power output (W) at the VO_{2 PEAK}(Parvo Medics TrueOne^®2400 Metabolic Measurement System, Sandy, Utah). In addition, one-repetition maximum (1-RM) strength was assessed using the bench press (BP) and leg press (LP) exercises. During visits 2 and 3, the subjects were asked to consume a capsule containing either the active supplement (200 mg caffeine, 33.34 mg capsaicin, 5 mg bioperine, and 20 mg niacin) or the placebo (175 mg of calcium carbonate, 160 mg of microcrystalline cellulose, 5 mg of stearic acid, and 5 mg of magnesium stearate in an identical capsule) 30 min prior to the testing.

The return of the fifties: Trends in college students' values between 1952 and 1984

Five identical surveys were carried out in 1952, 1968–1969, 1974, 1979, and 1984 among undergraduate men at Dartmouth College and the University of Michigan to measure value trends. In most value domains the trends are U-shaped, showing that the trends from the fifties to the sixties and seventies have reversed, and attitudes in 1984 were either similar to the fifties or moving in that direction. The domains include traditional religion, career choice, faith in government and the military, advocacy of social constraints on deviant social groups, attitudes about free enterprise, government and economics, sexual morality, marijuana use, and personal moral obligations. Two attitude areas do not show a return of the fifties: (1) other-direction was high in 1952, then dropped to the sixties and did not rise; (2) the level of politicization rose greatly from 1952 to the sixties, then dropped again only slightly.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/45659/1/11206_2005_Article_BF01106623.pd

The adverse effects of reduced cerebral perfusion on cognition and brain structure in older adults with cardiovascular disease

BACKGROUND: It is well established that aging and vascular processes interact to disrupt cerebral hemodynamics in older adults. However, the independent effects of cerebral perfusion on neurocognitive function among older adults remain poorly understood. We examined the associations among cerebral perfusion, cognitive function, and brain structure in older adults with varying degrees of vascular disease using perfusion magnetic resonance imaging (MRI) arterial spin labeling (ASL). MATERIALS AND METHODS: 52 older adults underwent neuroimaging and were administered the Mini Mental State Examination (MMSE), the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), and measures of attention/executive function. ASL and T1-weighted MRI were used to quantify total brain perfusion, total brain volume (TBV), and cortical thickness. RESULTS: Regression analyses showed reduced total brain perfusion was associated with poorer performance on the MMSE, RBANS total index, immediate and delayed memory composites, and Trail Making Test B. Reduced frontal lobe perfusion was associated with worse executive and memory function. A similar pattern emerged between temporal lobe perfusion and immediate memory. Regression analyses revealed that decreased total brain perfusion was associated with smaller TBV and mean cortical thickness. Regional effects of reduced total cerebral perfusion were found on temporal and parietal lobe volumes and frontal and temporal cortical thickness. DISCUSSION: Reduced cerebral perfusion is independently associated with poorer cognition, smaller TBV, and reduced cortical thickness in older adults. CONCLUSION: Prospective studies are needed to clarify patterns of cognitive decline and brain atrophy associated with cerebral hypoperfusion

Framing Homeless Policy: Reducing Cash Aid as a Compassionate Solution

In 2002, Care Not Cash/Proposition N was introduced to respond to public concern over San Francisco’s chronic homeless epidemic. The controversial initiative, which significantly reduced General Assistance (cash aid) to unhoused people, diverted funds to direct services such as shelter, food, medical assistance, and substance abuse programs. To investigate the underlying attitudes and beliefs that framed homelessness and the Care Not Cash policy in the months leading up to the citywide vote articles from the San Francisco Chronicle were analyzed. Of particular interest was assessing the prevalence of individualistic framing, constructions of dependency, and the problems Care Not Cash was presented as solving. Our analysis found that homelessness was framed as a threat to businesses, tourism, and residents of San Francisco and welfare as enabling deviant behavior (e.g., substance abuse) among people experiencing homelessness. Similar to federal welfare reform, Care Not Cash was portrayed as a compassionate solution that would both solve the problem of homelessness and address problematic behaviors associated with people who are unhoused (Stryker & Wald, 2009). Implications for economic justice are discussed.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/147013/1/asap12156_am.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/147013/2/asap12156.pd
