Three-loop HTL QCD thermodynamics

The hard-thermal-loop perturbation theory (HTLpt) framework is used to calculate the thermodynamic functions of a quark-gluon plasma to three-loop order. This is the highest order accessible by finite temperature perturbation theory applied to a non-Abelian gauge theory before the high-temperature infrared catastrophe. All ultraviolet divergences are eliminated by renormalization of the vacuum, the HTL mass parameters, and the strong coupling constant. After choosing a prescription for the mass parameters, the three-loop results for the pressure and trace anomaly are found to be in very good agreement with recent lattice data down to $T \sim 2-3\,T_c$, which are temperatures accessible by current and forthcoming heavy-ion collision experiments.Comment: 27 pages, 11 figures; corresponds with published version in JHE

Mindful Aging: The Effects of Regular Brief Mindfulness Practice on Electrophysiological Markers of Cognitive and Affective Processing in Older Adults

There is growing interest in the potential benefits of mindfulness meditation practices in terms of counteracting some of the cognitive effects associated with aging. Pursuing this question, the aim of the present study was to investigate the influence of mindfulness training on executive control and emotion regulation in older adults, by means of studying behavioral and electrophysiological changes. Participants, 55 to 75 years of age, were randomly allocated to an 8-week mindful breath awareness training group or an active control group engaging in brain training exercises. Before and after the training period, participants completed an emotional-counting Stroop task, designed to measure attentional control and emotion regulation processes. Concurrently, their brain activity was measured by means of 64-channel electroencephalography. The results show that engaging in just over 10 min of mindfulness practice five times per week resulted in significant improvements in behavioral (response latency) and electrophysiological (N2 event-related potential) measures related to general task performance. Analyses of the underlying cortical sources (Variable Resolution Electromagnetic Tomography, VARETA) indicate that this N2-related effect is primarily associated with changes in the right angular gyrus and other areas of the dorsal attention network. However, the study did not find the expected specific improvements in executive control and emotion regulation, which may be due to the training instructions or the relative brevity of the intervention. Overall, the results indicate that engaging in mindfulness meditation training improves the maintenance of goal-directed visuospatial attention and may be a useful strategy for counteracting cognitive decline associated with aging

Reading religion in Norwegian textbooks: are individual religions ideas or people?

Different religions are treated in different ways in Norwegian sixth form textbooks. We carried out an exhaustive content analysis of the chapters devoted to individual religions in textbooks for the Religion and Ethics course currently available in Norway, using rigorous indicators to code each word, image and question according to whether they were treated the religion as a set of ideas or a group of people. After adjusting for trends in the different kinds of data (word, image, question), we found that Buddhism and Christianity receive significantly more attention for their ideas than Hinduism, Islam and Judaism, which are treated more as people. This difference cannot be explained by the national syllabus or the particularities of the individual religions. The asymmetry also has implications for the pupils’ academic, moral and pedagogical agency for which teachers play a critical role in compensating.acceptedVersio

Associations between general self-efficacy and health-related quality of life among 12-13-year-old school children: a cross-sectional survey

<p>Abstract</p> <p>Background</p> <p>While research on school children's health has mainly focused on risk factors and illness, few studies have examined aspects of health promotion. Thus, this study focuses on health promotional factors including general self-efficacy (GSE) and health-related quality of life (HRQOL). GSE refers to a global confidence in coping ability across a wide range of demanding situations, and is related to health. The purpose of this study was to examine associations between GSE and HRQOL, and associations between HRQOL and socio-demographic characteristics. Knowledge of these associations in healthy school children is currently lacking.</p> <p>Methods</p> <p>During 2006 and 2007, 279 school children in the seventh grade across eastern Norway completed a survey assessing their GSE and HRQOL. The children were from schools that had been randomly selected using cluster sampling. T-tests were computed to compare mean subscale values between HRQOL and socio-demographic variables. Single and multiple regression analyses were performed to explore associations among GSE, HRQOL and socio-demographic variables.</p> <p>Results</p> <p>Regression analyses showed a significant relationship between increasing degrees of GSE and increasing degrees of HRQOL. In analyses adjusted for socio-demographic variables, boys scored higher than girls on self-esteem. School children from single-parent families had lower scores on HRQOL than those from two-parent families, and children who had relocated within the last five years had lower scores on HRQOL than those who had not relocated.</p> <p>Conclusion</p> <p>The strong relationship between GSE and HRQOL indicates that GSE might be a resource for increasing the HRQOL for school children.</p

Somatocognitive therapy in the management of chronic gynaecological pain. A review of current approach and historical background

Abstract Introduction We have developed somatocognitive therapy as a hybrid of Mensendieck physiotherapy and cognitive psychotherapy. Womenwith chronic pelvic pain (CPP) and vulvodynia (chronic pain of the vulvae and vestibulum, VD) were recruited into two separate treatment protocols as described. Methods 60 patients with CPP were recruited from the Department of Gynaecology at the Oslo University Hospital into a randomized, controlled intervention study. The patients were randomized into three treatment groups, receiving (1) treatment as usual, (2) somatocognitive therapy, and (3) in addition receiving cognitive therapy. The patients were assessed by means of SMT, Visual Analogue Score of Pain (VAS), and General Health Questionnaire (GHQ-30) at baseline, after three months of out-patient therapy and at 1 year follow-up. 9 women with VD were treated in an outpatient setting by physiotherapy students under senior supervision, each receiving in all 16 therapy sessions over 8 weeks, and scored for motor patterns (SMT) and pain (VAS) before and after therapy. Results In the control group, no significant change was found. In the group receiving somatocognitive therapy, significant reduction in pain score and improvement in motor function were found the end of therapy, and the significant improvement continued through the follow-up period. GHQ scores were significantly improved for the scores representing level of anxiety and coping, and improved for depression. In the group receiving cognitive therapy in addition, the VAS scores were reduced to the same level as the group receiving only somatocognitive therapy, whereas the motor patterns showed slightly less improvement than for those women that did not receive cognitive intervention. In the women with VD somatocognitive therapy resulted in significantly reduction in pain scores (by an average of 66%), and significant improvement of motor patterns, especially for the scores for gait (56%) and respiration (88%). Conclusions Somatocognitive therapy is a new approach that appears to be very promising in the management of chronic gynaecological pain. Short-term out-patient treatment significantly reduces pain scores and improves motor function, especially with respect to respiration, gait and movement (ability to relax). The approach is now being used in a randomized, controlled intervention study including patient with chronic low back, neck and shoulder, and widespread pain. </jats:sec

The INSPIRE study: are different personality traits related to disease-specific quality of life (IBDQ) in distressed patients with ulcerative colitis and Crohn's disease?

BACKGROUND: To explore the relationship between personality and disease-specific quality of life [Inflammatory Bowel Disease Questionnaire (IBDQ)] in distressed [Perceived Stress Questionnaire (PSQ)] patients with ulcerative colitis (UC) and Crohn's disease (CD). METHODS: Included in the study were 56 patients with UC and 54 patients with CD ranging in age from 18 to 60 years with a relapse in the previous 18 months, a UC or CD activity index 4, a PSQ 60, and without serious mental or other serious medical condition. The patients completed the Buss-Perry Aggression Questionnaire, the Neuroticism and Lie (social conformity/desirability) scales of the Eysenck Personality Questionnaire, the Multidimensional Health Locus of Control (LOC) Scale [Internal (I), Powerful Other (PO), Chance (C)], the Toronto Alexithymia Scale, and the IBDQ. RESULTS: In linear regression controlling for sex, education (years), and clinical disease activity (AI) in separate analyses of UC and CD patients, higher IBDQ score was related to less social conformity in CD and less neuroticism in UC; higher emotional function score was related to less neuroticism in both CD and UC and less PO-LOC in UC. Higher social function score was related to less social conformity in CD and lower I-LOC and PO-LOC in UC. Bowel function and systemic symptoms were unrelated to personality in either UC or CD. CONCLUSIONS: Although the emotional function subscale was related to neuroticism in both UC and CD, the social function subscale and total IBDQ were related to different personality traits in UC and CD. Personality traits should be taken into account when using IBDQ in studies

The INSPIRE study: do personality traits predict general quality of life (Short form-36) in distressed patients with ulcerative colitis and Crohn's disease?

OBJECTIVE: To assess the role of personality as a predictor of Short form-36 (SF-36) in distressed patients (perceived stress questionnaire, PSQ) with ulcerative colitis (UC) and Crohn's disease (CD). MATERIAL AND METHODS: Fifty-four patients with CD and 55 with UC (age 18-60 years) who had relapsed in the previous 18 months, i.e. with an activity index (AI) for UC or CD> or =4, PSQ> or =60, and without severe mental or other major medical conditions, completed the Buss-Perry Aggression Questionnaire (BPA), the Neuroticism and Lie scales of the Eysenck Personality Questionnaire (EPQ-N and -L), the Multidimensional Health Locus of Control Scale (LOC) (Internal (I), Powerful Other (PO), Chance (C)), the Toronto Alexithymia Scale (TAS) and the SF-36. RESULTS: Multiple linear regression analyses controlling for gender, age and clinical disease activity (AI) in separate analyses for UC and CD showed that the mental and vitality subscales were predicted by neuroticism in both UC and CD. The highest explained variance was 43.8% on the "mental" subscale in UC. The social function subscale was related to alexithymia only in UC, while the role limitation and pain subscales were related to personality in CD only. The physical function subscale related differently to personality in UC and CD. CONCLUSIONS: While mental and vitality subscales were predicted by neuroticism in both UC and CD, other subscales had different relationships to personality, suggesting different psychobiological interactions in UC and CD
