The mixed problem in Lipschitz domains with general decompositions of the boundary
This paper continues the study of the mixed problem for the Laplacian. We
consider a bounded Lipschitz domain , , with
boundary that is decomposed as , and disjoint.
We let denote the boundary of (relative to ) and
impose conditions on the dimension and shape of and the sets and
. Under these geometric criteria, we show that there exists
depending on the domain such that for in the interval ,
the mixed problem with Neumann data in the space and Dirichlet data in
the Sobolev space has a unique solution with the non-tangential
maximal function of the gradient of the solution in . We
also obtain results for when the Dirichlet and Neumann data comes from
Hardy spaces, and a result when the boundary data comes from weighted Sobolev
spaces.Comment: 36 page
Cognitiveâbehavioural therapy for adult attention-deficit hyperactivity disorder:a proof of concept randomised controlled trial
Objective: To investigate efficacy, patient acceptability and feasibility of formulation-based cognitiveâbehavioural therapy (CBT) for adults with attention-deficit hyperactivity disorder (ADHD). NICE guidelines for adult ADHD recommend further research into psychological treatments. Method: Sixty participants with adult ADHD were randomly allocated to treatment as usual (TAU) vs. TAU plus up to 16 sessions of individual formulation-based CBT for ADHD. Results: Adding formulation-based CBT to TAU for ADHD significantly improved ADHD symptoms on the Barkley Current Symptoms Scale and scores on the Work and Social Adjustment Scale. Adjusted effect sizes (ES) were 1.31 and 0.82 respectively. There were also significant improvements on secondary outcomes including independently evaluated clinical global improvement, self-rated anxiety, depression, global distress and patient satisfaction (adjusted effect sizes 0.52â1.01). Conclusions: This is the first randomised controlled trial to provide preliminary evidence of efficacy and acceptability of individual formulation-based CBT for ADHD when added to TAU over TAU alone. This approach now needs to be tested in a larger multicentred randomised controlled trial.</p

Surgery for the treatment of obesity in children and adolescents
Background Child and adolescent overweight and obesity have increased globally, and are associated with significant short and long term health consequences. Objectives To assess the effects of surgical interventions for treating obesity in childhood and adolescence. Search methods We searched the Cochrane Library, MEDLINE, PubMed, EMBASE as well as LILACS, ICTRP Search Portal and ClinicalTrials.gov (all from database inception to March 2015). References of identified studies and systematic reviews were checked. No language restrictions were applied. Selection criteria We selected randomised controlled trials (RCTs) of surgical interventions for treating obesity in children and adolescents (age <18 years) with a minimum of six months follow-up. Interventions that specifically dealt with the treatment of eating disorders or type 2 diabetes, or included participants with a secondary or syndromic cause of obesity were excluded. Pregnant females were also excluded. Data collection and analysis Two review authors independently assessed risk of bias and extracted data. Where necessary authors were contacted for additional information. Main results We included one RCT (a total of 50 participants, 25 in both the intervention and comparator group). The intervention focused on laparoscopic adjustable gastric banding surgery, which was compared to a control group receiving a multi component lifestyle programme. The participating population consisted of Australian adolescents (a higher proportion of girls than boys) aged 14 to 18 years, with a mean age of 16.5 and 16.6 years in the gastric banding and lifestyle group, respectively which was conducted in a private hospital, receiving funding from the gastric banding manufacturer. The study authors were unable to blind participants, personnel and outcome assessors which may have resulted in a high risk of performance and detection bias. Attrition bias was noted as well. The study authors reported a mean reduction in weight of 34.6 kg (95% confidence interval (CI) 30.2 to 39.0) at two years, representing a change in body mass index (BMI) of 12.7 (95% CI 11.3 to 14.2) for the surgery intervention; and a mean reduction in weight of 3.0 kg (95% CI 2.1 to 8.1) representing a change in BMI of 1.3 (95% CI 0.4 to 2.9) for the lifestyle intervention. The differences between groups were statistically significant for all weight measures at 24 months (P <0.001). The overall quality of the evidence according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE) was low. Adverse events were reported in 12/25 (48%) participants in the intervention group compared to 11/25 (44%) in the control group (low quality evidence). A total of 28% of the adolescents undergoing gastric banding required revisional surgery. No data were reported for all-cause mortality, behaviour change, participants views of the intervention and socioeconomic effects. At two years, the gastric banding group performed better than the lifestyle group in two of eight health-related quality of life concepts (very low quality evidence) as measured by the Child Health Questionnaire (physical functioning score (94 versus 78, community norm 95) and change in health score (4.4 versus 3.6, community norm 3.5)). Authors' conclusions Laparoscopic gastric banding led to greater body weight loss compared to a multi component lifestyle program in one small study with 50 patients. These results do not provide enough data to assess efficacy across populations from different countries, socioeconomic and ethnic backgrounds, who may respond differently. This systematic review highlights the lack of RCTs in this field. Future studies should assess the impact of the surgical procedure and post operative care to minimise adverse events, including the need for post operative adjustments and revisional surgery. Long-term follow-up is also critical to comprehensively assess the impact of surgery as participants enter adulthood
âTrue fan = watch matchâ? In Search of the âAuthenticâ Soccer Fan.
Academics have created typologies to divide association football (soccer) fans into categories based upon the assumed âauthenticityâ of their fandom practices. One of the main requirements of âauthenticâ fandom has been assumed to be match attendance. The goal of this paper was to critically assess this assumption through considering how fans themselves talk about the significance of match attendance as evidence of âauthenticâ fandom. In light of the fact that the voices of English non-league fans on the âauthenticityâ debate have so far been overshadowed by the overbearing focus of much previous research on the upper echelons of English soccer, an e-survey was conducted with 151 members of an online community of fans of English Northern League (NL) clubs (a semi-professional / amateur league based in North East England). Findings revealed that opinion was divided on the constituents of âauthenticâ fandom and match attendance was not deemed to be the core evidence of support for a club by 42% of the sample. Elias (1978) suggested that dichotomous thinking hinders sociological understanding and it is concluded that fan typologies are not sufficient for assessing the âauthenticityâ of fan activities
The mixed problem for the Laplacian in Lipschitz domains
We consider the mixed boundary value problem or Zaremba's problem for the
Laplacian in a bounded Lipschitz domain in R^n. We specify Dirichlet data on
part of the boundary and Neumann data on the remainder of the boundary. We
assume that the boundary between the sets where we specify Dirichlet and
Neumann data is a Lipschitz surface. We require that the Neumann data is in L^p
and the Dirichlet data is in the Sobolev space of functions having one
derivative in L^p for some p near 1. Under these conditions, there is a unique
solution to the mixed problem with the non-tangential maximal function of the
gradient of the solution in L^p of the boundary. We also obtain results with
data from Hardy spaces when p=1.Comment: Version 5 includes a correction to one step of the main proof. Since
the paper appeared long ago, this submission includes the complete paper,
followed by a short section that gives the correction to one step in the

Static posturography as a novel measure of the effects of aging on postural control in dogs
Aging is associated with impairment in postural control in humans. While dogs are a powerful model for the study of aging, the associations between age and postural control in this species have not yet been elucidated. The aims of this work were to establish a reliable protocol to measure center of pressure excursions in standing dogs and to determine age-related changes in postural sway. Data were obtained from 40 healthy adult dogs (Group A) and 28 senior dogs (Group B) during seven trials (within one session of data collection) of quiet standing on a pressure sensitive walkway system. Velocity, acceleration, root mean square, 95% ellipse area, range and frequency revolve were recorded as measures of postural sway. In Group A, reliability was assessed with intraclass correlation, and the effect of morphometric variables was evaluated using linear regression. By means of stepwise linear regression we determined that root mean square overall and acceleration in the craniocaudal direction were the best variables able to discriminate between Group A and Group B. The relationship between these two center-of-pressure (COP) measures and the dogsâ fractional lifespan was examined in both groups and the role of pain and proprioceptive deficits was evaluated in Group B. All measures except for frequency revolve showed good to excellent reliability. Weight, height and length were correlated with most of the measures. Fractional lifespan impacted postural control in Group B but not Group A. Joint pain and its interaction with proprioceptive deficits influence postural sway especially in the acceleration in the craniocaudal direction, while fractional lifespan was most important in the overall COP displacement. In conclusion, our study found that pressure sensitive walkway systems are a reliable tool to evaluate postural sway in dogs; and that postural sway is affected by morphometric parameters and increases with age and joint pain
