‘How I feel About My School’: The construction and validation of a measure of wellbeing at school for primary school children

This is the author accepted manuscript. The final version is available from Elsevier via the DOI in this record.There is a growing focus on child wellbeing and happiness in schools, but we lack self-report measures for very young children. Three samples (N = 2345) were combined to assess the psychometric properties of the How I Feel About My School (HIFAMS) questionnaire, which was designed for children aged 4-8 years. Test re-test reliability was moderate (intraclass correlation coefficient = 0.62). HIFAMS assessed a single concept and had moderate internal consistency (Cronbach’s alpha values from 0.62 to 0.67). There were low correlations between scores on the child-reported HIFAMS and parent- and teacher reports. Children at risk of exclusion had significantly lower HIFAMS scores than the community sample (mean difference = 2.4; 95% CI: 1.6 to 3.2; p < 0.001). Schools contributed only 4.5% of the variability in HIFAMS score; the remaining 95.5% reflecting pupil differences within schools. Girls’ scores were 0.37 units (95% CI: 0.16 to 0.57; p < 0.001) higher than boys, while year group and deprivation did not predict HIFAMS score. HIFAMS is a promising measure that demonstrates moderate reliability and discriminates between groups even among very young children

Representing spray zone with cross flow as a well-mixed compartment in a high shear granulator

The spray zone is an important region to control nucleation of granules in a high shear granulator. In this study, a spray zone with cross flow is quantified as a well-mixed compartment in a high shear granulator. Granulation kinetics is quantitatively derived at both particle-scale and spray zone-scale. Two spatial decay rates, DGSDR (droplet-granule spatial decay rate) ζDG and DPSDR (droplet-primary particle spatial decay rate) ζDP, which are functions of volume fraction and diameter of particulate species within the powder bed, are defined to simplify the deduction. It is concluded that in cross flow, explicit analytical results show that the droplet concentration is subject to exponential decay with depth which produces a numerically infinite depth of spray zone in a real penetration process. In a well-mixed spray zone, the depth of the spray zone is 4/(ζDG + ζDP) and π2/3(ζDG + ζDP) in cuboid and cylinder shape, respectively. The first-order droplet-based collision rates of, nucleation rate B0 and rewetting rate RW0 are uncorrelated with the flow pattern and shape of the spray zone. The second-order droplet-based collision rate, nucleated granule-granule collision rate RGG, is correlated with the mixing pattern. Finally, a real formulation case of a high shear granulation process is used to estimate the size of the spray zone. The results show that the spray zone is a thin layer at the powder bed surface. We present, for the first time, the spray zone as a well-mixed compartment. The granulation kinetics of a well-mixed spray zone could be integrated into a Population Balance Model (PBM), particularly to aid development of a distributed model for product quality prediction

Impacts of climate change on plant diseases – opinions and trends

There has been a remarkable scientific output on the topic of how climate change is likely to affect plant diseases in the coming decades. This review addresses the need for review of this burgeoning literature by summarizing opinions of previous reviews and trends in recent studies on the impacts of climate change on plant health. Sudden Oak Death is used as an introductory case study: Californian forests could become even more susceptible to this emerging plant disease, if spring precipitations will be accompanied by warmer temperatures, although climate shifts may also affect the current synchronicity between host cambium activity and pathogen colonization rate. A summary of observed and predicted climate changes, as well as of direct effects of climate change on pathosystems, is provided. Prediction and management of climate change effects on plant health are complicated by indirect effects and the interactions with global change drivers. Uncertainty in models of plant disease development under climate change calls for a diversity of management strategies, from more participatory approaches to interdisciplinary science. Involvement of stakeholders and scientists from outside plant pathology shows the importance of trade-offs, for example in the land-sharing vs. sparing debate. Further research is needed on climate change and plant health in mountain, boreal, Mediterranean and tropical regions, with multiple climate change factors and scenarios (including our responses to it, e.g. the assisted migration of plants), in relation to endophytes, viruses and mycorrhiza, using long-term and large-scale datasets and considering various plant disease control methods

Mental health consultations in a prison population: a descriptive study

BACKGROUND: The psychiatric morbidity among prison inmates is substantially higher than in the general population. We do, however, have insufficient knowledge about the extent of psychiatric treatment provided in our prisons. The aim of the present study was to give a comprehensive description of all non-pharmacological interventions provided by the psychiatric health services to a stratified sample of prison inmates. METHODS: Six medium/large prisons (n = 928) representing 1/3 of the Norwegian prison population and with female and preventive detention inmates over-sampled, were investigated cross-sectionally. All non-pharmacological psychiatric interventions, excluding pure correctional programs, were recorded. Those receiving interventions were investigated further and compared to the remaining prison population. RESULTS: A total of 230 of the 928 inmates (25 %) had some form of psychiatric intervention: 184 (20 %) were in individual psychotherapy, in addition 40 (4 %) received ad hoc interventions during the registration week. Group therapy was infrequent (1 %). The psychotherapies were most often of a supportive (62 %) or behavioural-cognitive (26 %) nature. Dynamic, insight-oriented psychotherapies were infrequent (8 %). Concurrent psychopharmacological treatment was prevalent (52 %). Gender and age did not correlate with psychiatric interventions, whereas prisoner category (remanded, sentenced, or preventive detention) did (p < 0.001). Most inmates had a number of defined problem areas, with substance use, depression, anxiety, and personality disorders most prevalent. Three percent of all inmates were treated for a psychotic disorder. Remand prisoners averaged 14 sessions per week per 100 inmates, while sentenced inmates and those on preventive detention averaged 22 and 25 sessions per week per 100 inmates, respectively. Five out of six psychiatric health services estimated the inmates' psychiatric therapy needs as adequately met, both overall and in the majority of individual cases. CONCLUSION: Our results pertain only to prisons with adequate primary and mental health services and effective diversion from prison of individuals with serious mental disorders. Given these important limitations, we do propose that the service estimates found may serve as a rough guideline to the minimum number of sessions a prison's psychiatric health services should be able to fulfil in order to serve the inmates psychiatric needs. The results rely on the specialist services' own estimates only. Future studies should take other important informants, including the inmates themselves, into consideration

Prospective randomized trial to compare the outcome and tolerability of delivering the same total dose of radiation in 61/2 weeks versus 51/2 weeks time in head and neck cancers

Background: Concurrent chemoradiation is currently considered to be the standard of care in the treatment of head and neck cancer. In developing countries like ours, a good number of patients cannot tolerate chemoradiation because of the poor general condition and financial constraints. Those patients are treated with radiation alone. The optimum radiotherapy (RT) schedule for best local control and acceptable toxicity is not yet clear. We aimed to find out whether shortening of treatment time using six instead of five RT fractions per week improves the locoregional control in squamous cell carcinoma of head and neck. Materials and Methods: We conducted a prospective randomized study for a period of 2 years from September 2007 to August 2009 in 109 untreated patients of squamous cell carcinoma of head and neck with histologically confirmed diagnosis and no evidence of distant metastasis. Study group (55 patients) received accelerated RT with 6 fractions per week (66 Gy/33#/51/2 weeks). Control group (54 patients) received conventional RT with 5 fractions per week (66 Gy/33#/61/2 weeks). Tumor control, survival, acute and late toxicities were assessed. Results: At a median follow-up of 43 months, 29 patients (52.7%) in the 6 fractions group and 24 patients (44.4%) in the 5 fractions group were disease-free (P = 0.852). The benefit of shortening was higher for advanced disease control though it was not statistically significant. Grade 3 and 4 skin toxicity was significantly higher in the accelerated RT (70.9%) arm as compared to conventional (35.1%) arm (P = 0.04). Grade 3 mucositis was significantly higher in the accelerated RT arm (32.7% vs. 16.6%; P = 0.041). Those acute toxicities were managed conservatively. There was no difference in late toxicities between the two arms. Conclusion: Use of 6 fractions per week instead of 5 fractions per week is feasible, tolerable, and results in a better outcome in the patients of head and neck cancers
