Model Predictive Control Based Wind-Solar Hybrid Energy Conversion System

Presently a lot of work is being carried in the field of distributed renewable generation. Many distributed generation systems are being designed and connected to the electric grid. At the time when the conventional sources of energy such as coal, oil, gas etc. are fast disappearing, a study of distributed renewable generation systems becomes very important

Cultural competence in mental health care: a review of model evaluations

BACKGROUND: Cultural competency is now a core requirement for mental health professionals working with culturally diverse patient groups. Cultural competency training may improve the quality of mental health care for ethnic groups. METHODS: A systematic review that included evaluated models of professional education or service delivery. RESULTS: Of 109 potential papers, only 9 included an evaluation of the model to improve the cultural competency practice and service delivery. All 9 studies were located in North America. Cultural competency included modification of clinical practice and organizational performance. Few studies published their teaching and learning methods. Only three studies used quantitative outcomes. One of these showed a change in attitudes and skills of staff following training. The cultural consultation model showed evidence of significant satisfaction by clinicians using the service. No studies investigated service user experiences and outcomes. CONCLUSION: There is limited evidence on the effectiveness of cultural competency training and service delivery. Further work is required to evaluate improvement in service users' experiences and outcomes

Screening of minor psychiatric disorders and burnout among a sample of medical students in St. Petersburg, Russia: a descriptive study

Abstract Background Despite the general interest of researchers around the world, there are few studies on the psychological wellbeing and burnout among medical students in Russia. The aim of this study was to perform screening for minor psychiatric disorders, burnout, problematic alcohol use, and quantify the psychological issues and stress among a sample of medical students in St. Petersburg, Russia. Results According to the GHQ-12, screening for minor mental disorders was positive in 140 students (85%). Screening for burnout using the OLBI showed positive results in 121 (73%) students for disengagement and 132 (80%) students for exhaustion. Screening with the CAGE tool identified a risk of alcohol consumption in 33 students (20%). Most students reported academic studies as the main source of stress in their life (n = 147; 89.1%). Conclusions This study identified very high levels of stress, burnout, risk of minor mental disorders, and problematic alcohol use among medical students in St. Petersburg, Russia. These findings suggest more attention is needed to the poor mental wellbeing and health in medical students in Russia

Rates, risk factors & methods of self harm among minority ethnic groups in the UK: a systematic review

<p>Abstract</p> <p>Background</p> <p>Studies suggest that the rates of self harm vary by ethnic group, but the evidence for variation in risk factors has not been synthesised to inform preventive initiatives.</p> <p>Methods</p> <p>We undertook a systematic literature review of research about self harm that compared at least two ethnic groups in the United Kingdom.</p> <p>Results</p> <p>25 publications from 1765 titles and abstracts met our inclusion criteria. There was higher rate of self harm among South Asian women, compared with South Asian men and White women. In a pooled estimate from two studies, compared to their white counterparts, Asian women were more likely to self harm (Relative Risk 1.4, 95%CI: 1.1 to 1.8, p = 0.005), and Asian men were less likely to self harm (RR 0.5, 95% CI: 0.4 to 0.7, p < 0.001). Some studies concluded that South Asian adults self-harm impulsively in response to life events rather than in association with a psychiatric illness. Studies of adolescents showed similar methods of self harm and interpersonal disputes with parents and friends across ethnic groups. There were few studies of people of Caribbean, African and other minority ethnic groups, few studies took a population based and prospective design and few investigated self harm among prisoners, asylum seekers and refugees.</p> <p>Conclusion</p> <p>This review finds some ethnic differences in the nature and presentation of self harm. This argues for ethnic specific preventive actions. However, the literature does not comprehensively cover the UK's diverse ethnic groups.</p

Effectiveness of guided self-help in decreasing expressed emotion in family caregivers of people diagnosed with depression in Thailand: a randomised controlled trial

Background: High expressed emotion (EE) can extend the duration of illness and precipitate relapse; however, little evidence-based information is available to assist family caregivers of individuals with depression. In the present exploratory study, we examined the effectiveness of a cognitive behaviour therapy (CBT) based guided self-help (GSH) manual in decreasing EE in caregivers of people with depression, in Thailand. Method: A parallel group randomised controlled trial was conducted, following CONSORT guidelines, with 54 caregivers who were allocated equally to GSH or control group (standard outpatient department support). In addition, both groups were contacted weekly by telephone. EE was assessed, using the Family Questionnaire (FQ), at baseline, post-test (Week 8) and follow-up (Week 12). Results: FQ scores at baseline indicated that both groups had similar, though moderately high level of EE. However, between baseline and post-test EE scores decreased markedly in the intervention group, but in contrast, they increased slightly in the control group. Between post-test and follow-up, little change took place in the EE scores of either group. Overall, the intervention group recipients of GSH showed a significant decrease in EE whereas the control group recipients of standard outpatient department support reported a slight increase in EE. Conclusion: These findings provide preliminary evidence that GSH is beneficial in reducing EE in caregivers, which is advantageous to family members with depression and caregivers. The approach may be used as an adjunct to the limited outpatient department support given to caregivers by mental health professionals and, perhaps, to caregivers who do not attend these departments

WPA guidance on mental health and mental health care in migrants

The WPA is committed to promote equity in the access to mental health services for persons of different age, gender, race/ethnicity, religion and socioeconomic status. As part of this commitment, the Association decided to devote one of the guidances to be developed within its Action Plan 2008-2011 (1,2) to mental health and mental health care in migrants. A Task Force was appointed for this purpose, which produced the present document. Mental health practitioners work in an increasingly multicultural world, shaped by the migrations of people of many different cultural, racial and ethnic backgrounds. People migrate for many reasons: political, socioeconomic and educational. The diversity of cultures, ethnicity, races and reasons for migration can make understanding experiences of illness challenging in migrants whose background differs significantly from the clinician. Culture has an important role in the presentation of distress and illness, and cultural differences impact upon the diagnosis and treatment of migrant populations in part due to linguistic, religious and social variation from the clinician providing care. Additionally, it appears that the incidence and prevalence of mental disorders varies among people of different cultural backgrounds, due to an interplay of biological, psychological and social factors. The provision of health care is necessarily influenced by the demands of people of many different cultures, and it is important that cultural differences be appreciated and understood to arrive at a correct diagnostic impression and treatment plan

Compulsory admission at first presentation to services for psychosis: does ethnicity still matter? Findings from two population-based studies of first episode psychosis

Objectives Compared with the majority population, those from minority ethnic groups in the UK are more likely to be admitted compulsorily during a first episode of psychosis (FEP). We investigated whether these disparities in pathways in to care continue. Methods We analysed data from two first episode psychosis studies, conducted in the same geographical area in south London 15 years apart: the Aetiology and Ethnicity in Schizophrenia and Other Psychosis (AESOP) and the Clinical Record Interactive Search-First Episode Psychosis (CRIS-FEP) studies. The inclusion/exclusion criteria for case ascertainment for first episode psychosis were identical across the two studies. We performed multivariable logistic regression to estimate odds of compulsory admission by ethnic group, controlling for confounders. Participants Two hundred sixty-six patients with first episode psychosis, aged 18–64 years, who presented to mental health services in south London in 1997–1999 and 446 with FEP who presented in 2010–2012. Results When the two samples were compared, ethnic differences in compulsory admission appear to have remained the same for black African patients, i.e. three times higher than white British in both samples: AESOP (adj. OR = 3.96; 95% CI = 1.80–8.71) vs. CRIS-FEP (adj. OR = 3.12; 95% CI = 1.52–6.35). Black Caribbean patients were three times more likely to be compulsorily admitted in AESOP (adj. OR = 3.20; 95% CI = 1.56–6.54). This was lower in the CRIS-FEP sample (adj. OR = 1.68; 95% CI = 0.71–3.98) and did not meet conventional levels for statistical significance. Conclusion Ethnicity is strongly associated with compulsory admissions at first presentation for psychosis with evidence of heterogeneity across groups, which deserves further research

Child mental health differences amongst ethnic groups in Britain: a systematic review

BACKGROUND: Inter-ethnic differences have been reported for many mental health outcomes in the UK, but no systematic review on child mental health has been published. The aim of this review is to compare the population-based prevalence of child mental disorders between ethnic groups in Britain, and relate these findings to ethnic differences in mental health service use. METHODS: A systematic search of bibliographic databases for population-based and clinic-based studies of children aged 0-19, including all ethnic groups and the main child mental disorders. We synthesised findings by comparing each minority group to the White British study sample. RESULTS: 31 population-based and 18 clinic-based studies met the inclusion criteria. Children in the main minority groups have similar or better mental health than White British children for common disorders, but may have higher rates for some less common conditions. The causes of these differences are unclear. There may be unmet need for services among Pakistani and Bangladeshi children. CONCLUSION: Inter-ethnic differences exist but are largely unexplained. Future studies should address the challenges of cross-cultural psychiatry and investigate reasons for inter-ethnic differences
