Accuracy of adults’ recall of childhood social class: findings from the Aberdeen children of the 1950s study

<b>Background</b>: Although adult reported childhood socioeconomic position has been related to health outcomes in many studies, little is known about the validity of such distantly recalled information. This study evaluated the validity of adults’ reports of childhood paternal social class. <b>Methods</b>: Data are drawn from the Aberdeen children of the 1950s study, a cohort of 12 150 people born in Aberdeen (Scotland) who took part in a school based survey in 1962. In this survey, two indices of early life socioeconomic position were collected: occupational social class at birth (abstracted from maternity records) and occupational social class in childhood (reported during the 1962 survey by the study participants). Between 2000 and 2003, a questionnaire was mailed to traced middle aged cohort members in which inquiries were made about their fathers’ occupation when they were aged 12 years. The level of agreement between these reports and prospectively collected data on occupational social class was assessed. <b>Results</b>: In total, 7183 (63.7%) persons responded to the mid-life questionnaire. Agreement was moderate between social class of father recalled in adulthood and that measured in early life ( statistics were 0.47 for social class measured at birth, and 0.56 for social class reported by the child). The relation of occupational social class to birth weight and childhood intelligence was in the expected directions, although weaker for adults’ reports in comparison with prospectively gathered data. <b>Conclusions</b>: In studies of adult disease aetiology, associations between childhood social class based on adult recall of parental occupation and health outcomes are likely to underestimate real effects

Children’s social experiences with peers and friends during primary school mealtimes

Mealtimes have rarely been considered outside a healthy eating agenda yet may be important social contexts for children’s social, emotional and moral development. Little research has examined the social value of time spent in the school lunch room. This study examined the nature of children’s interactions, activities and experiences of mealtimes and their perceptions of the value of social experiences during these times. A total of 316 9-10-year-old pupils (53% girls) from 11 classes in 4 schools completed closed response questionnaires and 16 children were subsequently interviewed to provide detailed information about the nature of their mealtime experiences, interactions and activities with peers and how these relate to feelings about school. Findings indicate that most children enjoy mealtimes because of the opportunity they provide to be with and converse with friends and other peers about the issues that are significant to them. These social occasions overlap with playground life but are distinctive and afford children different social opportunities and activities. The relative freedom offered in these settings make them important sites for peer relations processes and co-construction of peer culture. Findings are discussed in the light of suggestions that mealtimes should be managed for social and educational purposes

The sustainability of public health interventions in schools: a systematic review

Background: The sustainability of school-based health interventions after external funds and/or other resources end has been relatively unexplored in comparison to health care. If effective interventions discontinue, new practices cannot reach wider student populations and investment in implementation is wasted. This review asked: What evidence exists about the sustainability of school-based public health interventions? Do schools sustain public health interventions once start-up funds end? What are the barriers and facilitators affecting the sustainability of public health interventions in schools in high-income countries? Methods: Seven bibliographic databases and 15 websites were searched. References and citations of included studies were searched, and experts and authors were contacted to identify relevant studies. We included reports published from 1996 onwards. References were screened on title/abstract, and those included were screened on full report. We conducted data extraction and appraisal using an existing tool. Extracted data were qualitatively synthesised for common themes, using May's General Theory of Implementation (2013) as a conceptual framework. Results: Of the 9677 unique references identified through database searching and other search strategies, 24 studies of 18 interventions were included in the review. No interventions were sustained in their entirety; all had some components that were sustained by some schools or staff, bar one that was completely discontinued. No discernible relationship was found between evidence of effectiveness and sustainability. Key facilitators included commitment/support from senior leaders, staff observing a positive impact on students' engagement and wellbeing, and staff confidence in delivering health promotion and belief in its value. Important contextual barriers emerged: the norm of prioritising educational outcomes under time and resource constraints, insufficient funding/resources, staff turnover and a lack of ongoing training. Adaptation of the intervention to existing routines and changing contexts appeared to be part of the sustainability process. Conclusions: Existing evidence suggests that sustainability depends upon schools developing and retaining senior leaders and staff that are knowledgeable, skilled and motivated to continue delivering health promotion through ever-changing circumstances. Evidence of effectiveness did not appear to be an influential factor. However, methodologically stronger primary research, informed by theory, is needed. Trial registration: The review was registered on PROSPERO: CRD42017076320, Sep. 2017

180nm metal gate, high-k dielectric, implant-free III--V MOSFETs with transconductance of over 425 μS/μm

Abstract: Data is reported from 180 nm gate length GaAs n-MOSFETs with drive current (Ids,sat) of 386 μA/μm (Vg=Vd =1.5 V), extrinsic transconductance (gm) of 426 μS/μm, gate leakage ( jg,limit) of 44 nA/cm2, and on resistance (Ron) of 1640 Ω μm. The gm and Ron metrics are the best values reported to date for III-V MOSFETs, and indicate their potential for scaling to deca-nanometre dimensions

Groundwater Nutrient Discharge to the Chesapeake Bay: Effects of Near-Shore Land Use Practices

Groundwater discharge supplies a significant portion of the inorganic nutrients entering the Chesapeake Bay. This discharge increases nutrient concentration in surface waters, which may result in increased macrophyte growth, reductions in· submerged aquatic vegetation and alteration of habitat. Human activities adjacent to the shoreline greatly increase nutrient concentration in the underlying groundwater, and so affect the overall nutrient input by groundwater seepage. In order to quantify the effect of land use on groundwater nutrient loading in the Virginia coastal plain we have installed monitoring wells in a variety of near shore environments adjacent to the James and York Rivers. Since the Spring of 1988, groundwater nitrogen species concentrations have been monitored beneath agricultural fields planted with corn and soy beans, woodlands, vineyards, and suburban development with septic drain fields.

Actinomycosis

Actinomycosis is generally looked upon as a rare disease, but, in the experience of many who are constantly on the look out for this condition, this would appear to be by no means the case. It seems probable that many are mistaken for another of the infective granuloata, namely - Tuberculosis - which this disease resembles in many respects; or again for malignant disease. Early writers described conditions which were identical with actinomycosis, but classed them as Tuberculous or Cancerous affection. In France in 1826, Leblanc described a disease in cattle characterised by swelling of the jaw. In England in 1833, Professor Dick described a condition of swelling of the jaws in cattle called "clyers"; and, in 1841, stated that the disease was known to affect man in the jaw. In 1845 Langenbeck reported a case of vertebral caries, with yellow grains in the pus. In 1850, Davaine described a case of tumour of the jaw in an ox, in the discharge from which there were yellow granules, which under the microscope had neither the characters of tubercle nor of pus. In 1868, Rivolta discovered rod shaped bodies in pus from tumours of jaws of oxen, which rods he compared to rods of the retina. He attepted innoculation, but failed. Bollinger, in 1878, proved that the granules from the tumours of jaws of oxen had a casual relation to the disease: these same granules were examined by Harz, the botanist of Munich, who recognised their parasitic nature, and gave the name "Actinomycosis Bovis". Israel, in 1878, published in "Virchow's Archives" two cases of Mycosis in man, describing and making drawings of the fungus. In 1879, Ponfick suggested the identity of the disease in man and the lower animals. Then Johne succeeded in producing the disease in the ox by inoculation

COVID-19 outbreaks in aged-care facilities in Australia

Background: Aged-care facilities (ACF’s) provide unique challenges when implementing infection control methods for respiratory outbreaks such as COVID-19. Research on this highly vulnerable setting is lacking and there was no national reporting data of COVID-19 cases in ACFs in Australia early in the pandemic. We aimed to estimate the burden of aged-care worker (ACW) infections and outbreaks of COVID-19 in Australian aged-care. Methods: A line list of publicly available aged-care related COVID-19 reported cases from January 25 to June 10, 2020 was created and was enhanced by matching data extracted from media reports of aged-care related COVID-19 relevant outbreaks and reports. Rate ratios (RR) were used to predict risk of infection in ACW and aged-care residents, and were calculated independently, by comparing overall cases to ACW and aged-care residents' cases. Results: A total of 14 ACFs with COVID-19 cases were recorded by June 2020 nationwide, with a high case fatality rate (CFR) of 50% (n = 34) and 100% (n = 3) seen in two ACFs. Analysis on the resident risk found that the COVID-19 risk is 1.27 times higher (unadjusted RR 1.27 95% confidence interval [CI] 1.00 to1.61; P = 0.047) as compared with the risk of infection in the general population. In over 60% of cases identified in ACFs, the source of infection in the index case was unknown. A total of 28 deaths associated within ACFs were reported, accounting for 54.9% of total deaths in New South Wales and 26.9% of total deaths in Australia. Conclusions: This high-risk population requires additional prevention and control measures, such as routine testing of all staff and patients regardless of symptoms. Prompt isolation and quarantine as soon as a case is confirmed within a facility is essential
