Sexual Abuse: Journal of Research and Treatment | Year: 2013
Although there has been much speculation about the relationship between cognitive distortions and denial/minimization, little research on the subject is available. The authors conducted secondary analyses on existing data sets to further examine the degree of association between various measures of cognitive distortions and denial/minimization among child molesters (Sample 1, n = 73; Sample 2, n = 42; Sample 3, n = 38) and rapists (Sample 1, n = 41; Sample 3, n = 14). Meta-analysis of the findings from Samples 1, 2, and 3 indicated that greater endorsement of cognitive distortions about sex offending in general was significantly associated with greater denial/minimization of one's own guilt and deviance (r = .24), harm to one's own victims (r = .32), one's need for treatment (r = .21), and responsibility for one's sex offenses (r = .16). Although correlated, cognitive distortions and denial/minimization, at least as typically measured, are distinct constructs. © The Author(s) 2012.

We introduce Satisfiable Random High Degree Subgraph Isomorphism Generator(SRHD-SGI), a variation of the Satisfiable Random Subgraph Isomorphism Generator (SR-SGI). We use the direct encoding to translate the SRHD-SGI instances into Satisfiable SAT instances. We present empirical evidence that the new model preserves the main characteristics of SAT encoded SR-SGI: easy-hard-easy pattern of evolution and exponential growth of empirical hardness. Our experiments indicate that SAT encoded SRHD-SGI instances are empirically harder than their SR-SGI counterparts. Therefore we conclude that SRHD-SGI is an improved generator of satisfiable SAT instances. © 2011 Springer-Verlag.

In the first of this two-part series, we find 'fixed point factorisation' formulas, towards an understanding of the fusion ring of WZW models. Fixed-point factorization refers to the simplifications in the data of a CFT involving primary fields fixed by simple- currents. Until now, it has been worked out only for SU(n), where it has developed into a powerful tool for understanding the fusion rings of WZW models of CFT - e.g. it has lead to closed formulas for NIM-reps and D-brane charges and charge-groups. In this paper, we generalise these formulas to the other classical algebras, laying the groundwork for future applications to fusion rings (Part 2). We also discuss connections with the twining characters of Fuchs-Schellekens-Schweigert. © SISSA 2012.

Health Promotion International | Year: 2012
The health-promoting schools approach has gained momentum in the last decade with many jurisdictions providing guidelines and frameworks for general implementation. Although general agreement exists as to the broad strokes needed for effectiveness, less apparent are local implementation designs and models. The Battle River Project was designed to explore one such local implementation strategy for a provincial (Alberta, Canada) health promoting schools program. Located in the Battle River School Division, the project featured a partnership between Ever Active Schools, the school division and the local health authority. Case study was used to come to a greater understanding of how the health promoting schools approach worked in this particular school authority and model. Three themes emerged: participation, coordination and, integration. © 2012 The Author. Published by Oxford University Press. All rights reserved.

Research in Autism Spectrum Disorders | Year: 2012
Few studies have examined the sexual attitudes and behaviours of individuals with high functioning autism spectrum disorders (ASDs) living in community settings. A total of 82 (55 female and 17 male) adults with autism were contrasted with 282 members of the general population on their responses to an online survey of sexual knowledge and experiences. Findings revealed that individuals with ASD display an interest in sex and engage in sexual behaviours and showed no significant differences in breadth and strength of sexual behaviours and comprehension of sexual language when contrasted with non-ASD participants. However, despite these similarities, a higher rate of asexuality was found among individuals with ASD. In addition, the results of the current study indicated that females with ASD show a significantly lower degree of heterosexuality when compared to males with ASD. The results also suggested a higher degree of homosexuality among females with ASD although this effect did not reach significance.

Critically ill patients are at increased risk of developing delirium, which has been considered one of the most common complications of intensive care unit (ICU) hospitalization. Despite the high occurrence of delirium in the ICU, researchers have shown it is consistently overlooked and often undiagnosed. An understanding of delirium and the three clinical subtypes of hyperactive, hypoactive and mixed-type delirium that exist are key to early detection and treatment. Critical care nurses are in the frontline position to detect and monitor for risk factors that contribute to the development of delirium in the ICU. Recognition of predisposing risk factors and the elimination of precipitating risk factors for delirium can prevent the devastating short-term and long-term consequences for the critically ill patient. The importance of the use of validated assessment tools, such as the Confusion Assessment Method for the ICU (CAM-ICU) and the Intensive Care Delirium Screening Checklist (ICDSC) to detect key features of delirium development is emphasized. Recommendations to improve the practice of critical care nurses include continuing education regarding the causes, risk factors and treatments of delirium, and education sessions on the use of validated assessment tools. Early prevention strategies, such as modification of the ICU environment to promote normal sleep/wake cycles, including reduction of unit noise and nighttime interruptions, are examined as interventions to avoid the development of delirium.

A facile continuous flow-through Candida antarctica lipase B immobilized silica microstructured optical fiber (SMOF) microreactor for application in lipid transformations has been demonstrated herewith. The lipase was immobilized on the amino activated silica fiber using glutaraldehyde as a bifunctional reagent. The immobilized lipase activity in the SMOF was tested calorimetrically by determination of p-nitrophenyl butyrate hydrolysis products. The specific activity of the immobilized lipase was calculated to be 0.91 U/mg. The SMOF microreactor performance was evaluated by using it as a platform for synthesis of butyl laurate from lauric acid and n-butanol in n-hexane and n-heptane at 50 °C, with products identified by gas chromatography-mass spectrometry (GC-MS). Different substrate mole ratios were evaluated, with 1:3, lauric acid:n-butanol showing best performance. Remarkably, percentage yields of up to 99% were realized with less than ∼38 s microreactor residence time. In addition, the SMOF microreactor could be reused many times (at least 7 runs) with minimal reduction in the activity of the enzyme. The enzyme stability did not change even with storage of the microreactor in ambient conditions over one month. © 2010 Elsevier B.V. All rights reserved.

Objective: Guidelines from a variety of jurisdictions for the health-promoting schools (HPS) approach include healthy school policy as a critical element. Research also supports the importance of policy; however, there seems to be a lack of information on how to develop and implement policy. The article examines the processes involved in one school division's development and implementation of healthy school policy.Design: The study emerged from the Battle River Project, a multilevel partnership designed to explore the efficacy of implementing HPS at a school division level. The project intervention involved support for schools, a division-level steering committee, and a framework for implementation.Setting: The Battle River School Division is located in Alberta, Canada, and serves both rural and urban school communities. The study involved 21 of the 36 schools in the division and was initiated by the Ever Active Schools programme.Method: Development and implementation of policy and procedure were examined using case study methodology. Data gathered included interviews, focus groups, documents and observation.Results: Four primary themes were revealed through data analysis. Perceptions and misconceptions; bottom-up/top-down; flexible rigidity; and the way we do business.Conclusion: The process of developing and implementing healthy school policy can be streamlined by planning for clear communication, involving all stakeholders, and by embedding health into the structures of a school jurisdiction. © Health Education Journal 2010.

This paper discussed the different ways radio stations in North America engage listeners and provide immersive experiences via the use of mobile technology. The paper described several uses of mobile technology in radio and talked about ways broadcasters can improve engagement and, as a consequence, increase the number of listeners by deploying participatory or citizen journalism type of experiences on the part of the audience. A discussion on the best practices and utilization of convergent technology on radio is also included. Furthermore, the paper analyzed some of the pitfalls and challenges of using social media and mobile technology in today's radio broadcasting. © 2012 Elsevier Ltd. All rights reserved.

The current study used social cognitive theory as a conceptual framework to investigate whether college students' beliefs about their sleep were compatible with sleep education, and whether incompatibility was greater for evening than morning or intermediate types. Students at a Canadian college (n = 499) completed an investigator-designed measure of outcome expectancies about how their sleep is affected by recommended sleep practices, self-efficacy beliefs about the ease of implementing the recommendations, a question about sleep status (i.e., good sleeperpoor sleeper), and the Composite Scale of Morningness (CSM). Contrary to predictions, outcome expectations of evening types did not differ from those of morning or intermediate types for 24 of the 26 items. Chi square tests indicated that most students' beliefs about the effects of sleep scheduling, caffeine consumption, sleep environment, and bedtime arousal were compatible with sleep education, whereas those about exercising, doing stimulating or important work close to bedtime, or using their beds for studying or watching TV were incompatible with sleep education. Consistent with predictions, ANOVA results indicated that global self-efficacy scores of evening types were lower, as were their item scores pertaining to sleep scheduling (i.e., napping, bedtimes, rise times, and staying in bed too long) and cognitive arousal in bed (i.e., thinking, worrying, or problem solving in bed or going to bed stressed, angry, nervous, or upset) than were those of intermediate or morning types. Results of an ANCOVA showed that evening preference was associated with poorer self-efficacy when differences in sleep status were controlled. Finally, Pearson correlations and stepwise multiple regression showed evening preference and describing oneself as a poor sleeper both contributed to low self-efficacy. These findings are relevant to the refinement of sleep education. Content included in sleep education needs to consider what students already know about sleep so that education is relevant, credible, and not redundant. Sleep education also needs to address lower self-efficacy of evening types for implementing sleep recommendations. Conclusions reported in this study should be considered tentative because they were based on a single Canadian sample using a novel measure. The generalizability of the results remains to be determined. © Informa UK Ltd.
