Self-employment amongst migrant groups: New evidence for England and Wales

Self-employment constitutes a vital part of the economy since entrepreneurs can provide employment not only for themselves but also for others. The link between self-employment and immigration is, however, complex, especially given the changing nature of self-employment. We investigate the evolving relationship between self-employment and immigration using recently released microdata from the 2011 Census for England and Wales. Our findings indicate large variations, with high self-employment rates observed for some groups with a long established history of migration to the UK (especially men born in Pakistan) and also for some groups who have arrived more recently (such as from the EU’s new member states). We further explore the differences, analyse variations by gender and identify key determining factors. In addition to certain socio-economic characteristics, it is found that migration-related influences, such as English language proficiency and period of arrival in the UK, play an important role for some groups

DENTAL SURVEY IN NIGERIA PART: 4. PREVALENCE AND SEVERITY OF PERIODONTAL DISEASES

Six hundred and seventy-three school children from the age of 3 to 20 living in the urban and the rural areas of Nigeria were examined by the Joint Dental Epidemiological Survey in 1986. The survey was funded by the Grant-in Aid from the Japanese Ministry of Education, Science and Culture, and was conducted by both the Japanese survey team and the staff from the University of Ife, Ile-Ife, Nigeria. The periodontal state of the children was evaluated according to the Community Periodontal Index for Treatment Needs (CPITN) by WHO (1).The prevalence of periodontal diseases was found to be 84.2% within the sample with a high occurrence of gingivitis and heavy deposits of calculus. However, there was little evidence of damage to the periodontal tissues. This can be attributed to the nature of their diet. The results suggested that there would be an increasing need for well-planned and organized public educational programs for the Nigerian children to promote better Oral hygiene coupled with parental involvement in the prevention at home

Functional brain maturation assessed during early life correlates with anatomical brain maturation at term-equivalent age in preterm infants

Background: Amplitude-integrated electroencephalogram (aEEG) is a reliable monitoring tool for electrocortical activity with good predictive value in preterm infants. Magnetic resonance imaging (MRI) is a good neuroimaging tool to detect brain lesions and to evaluate brain maturation. We hypothesized that early aEEG measures, recorded over the first 3 d of life in very preterm infants, correlate with brain maturation and injury score assessed by conventional MRI at term-equivalent age.Methods:Thirty-nine infants born at a mean (range) gestational age (GA) of 29.5 (27.0-31.9) wk and birth weight 1,230 (680-2,020) g had continuous aEEG during the first postnatal 72-84 h. aEEG maturity scores and average maximum and minimum amplitudes were evaluated. Conventional brain MRI was performed at 41.2 (37.1-44.1) wk postmenstrual age (PMA) on a 3T GE system and scored qualitatively for injury and maturation.Results:The average aEEG total maturity score and its cycling subscore were positively and significantly associated with the total MRI maturation score after adjustment for GA, morphine sedation, and PMA at MRI examination. No association was found between the aEEG measures and the MRI injury scores.Conclusion:Early aEEG maturity seems to relate to structural MRI brain maturation at term-equivalent age in preterm infants
