Maternal and child welfare in England and Wales between the wars: a comparative regional study.

This study explores the factors which shaped the local maternal and child welfare services of the inter-war period. It draws on research from local authority minute books, local newspapers, and from mothers themselves. It shows the strong influences exerted by the complex interplay of geographical, economic, political and cultural factors in determining the shape of services in the four very different localities studied here. The services were very different in the different localities, in two of the four areas expensive for the mothers, offering little practical medical or material help, and relying heavily on voluntary effort to meet government targets of every scheme being as self-sufficient as possible. Although it is shown that those indices of maternal and infant health, the infant and maternal mortality rates, fell in all four areas studied, the precise connection between educating the mothers and better perinatal and infant health remains to be established

The Bridgwater Infant Welfare Centre, 1922-1939: from an authoritarian concern with 'welfare mothers' to a more inclusive community health project?

The infant welfare movement in Britain has received considerable scholarly attention but continues to generate controversy and debate. Many of the services began with nineteenth-century voluntary initiative but were later developed by local authorities. Critics have drawn attention to the limitations of such provision; arguing that it was predicated on unattractive assumptions about class and gender roles. Under this interpretation working-class mothers were viewed with suspicion and targeted for advice aimed at inculcating middle-class standards of childcare and housekeeping. This paper accepts that there was an authoritarian character to much of the early welfare work but suggests that over time this gave way to more inclusive approaches that sought to provide clients with the services that met their real rather than assumed needs. This paper reviews the recent historiography, develops an overview of national trends, and then takes a detailed look at the Bridgwater Infant Welfare Centre. The case study benefi ts from unusually comprehensive records and, by drawing on evidence from a small Somerset town, adds to our understanding of infant welfare work that has previously been developed from research on major urban centres.Wellcome Trust Fellowshi

Single-charge detection by an atomic precision tunnel junction

We demonstrate sensitive detection of single charges using a planar tunnel junction 8.5 nm wide and 17.2 nm long defined by an atomically precise phosphorus doping profile in silicon. The conductance of the junction responds to a nearby gate potential and also to changes in the charge state of a quantum dot patterned 52 nm away. The response of this detector is monotonic across the entire working voltage range of the device, which will make it particularly useful for studying systems of multiple quantum dots. The charge sensitivity is maximized when the junction is most conductive, suggesting that more sensitive detection can be achieved by shortening the length of the junction to increase its conductance

Investigation into pedestrian exposure to near-vehicle exhaust emissions

<p>Abstract</p> <p>Background</p> <p>Inhalation of diesel particulate matter (DPM) is known to have a negative impact on human health. Consequently, there are regulations and standards that limit the maximum concentrations to which persons may be exposed and the maximum concentrations allowed in the ambient air. However, these standards consider steady exposure over large spatial and time scales. Due to the nature of many vehicle exhaust systems, pedestrians in close proximity to a vehicle's tailpipe may experience events where diesel particulate matter concentrations are high enough to cause acute health effects for brief periods of time.</p> <p>Methods</p> <p>In order to quantify these exposure events, instruments which measure specific exhaust constituent concentrations were placed near a roadway and connected to the mouth of a mannequin used as a pedestrian surrogate. By measuring concentrations at the mannequin's mouth during drive-by events with a late model diesel truck, a representative estimate of the exhaust constituent concentrations to which a pedestrian may be exposed was obtained. Typical breathing rates were then multiplied by the measured concentrations to determine the mass of pollutant inhaled.</p> <p>Results</p> <p>The average concentration of diesel particulate matter measured over the duration of a single drive-by test often exceeded the low concentrations used in human clinical studies which are known to cause acute health effects. It was also observed that higher concentrations of diesel particulate matter were measured at the height of a stroller than were measured at the mouth of a mannequin.</p> <p>Conclusion</p> <p>Diesel particulate matter concentrations during drive-by incidents easily reach or exceed the low concentrations that can cause acute health effects for brief periods of time. For the case of a particularly well-tuned late-model year vehicle, the mass of particulate matter inhaled during a drive-by incident is small compared to the mass inhaled daily at ambient conditions. On a per breath basis, however, the mass of particulate matter inhaled is large compared to the mass inhaled at ambient conditions. Finally, it was determined that children, infants, or people breathing at heights similar to that of a passing vehicle's tailpipe may be exposed to higher concentrations of particulate matter than those breathing at higher locations, such as adults standing up.</p

Evaluation of the Beliefs of Parents in Iran about How to Care for Children During Dental Visits

Parents play an important role in their children’s dental care and in their behavior during dental visits. Separating children from their parents during dental visits has been a challenging subject of debate for many years. Therefore, this study aims to evaluate parents’ attitudes about being present during their children’s visits to the dentist. The subjects for this cross-sectional study included 340 Iranian parents of five-10-year-old children who had been referred to dental clinics in Kerman, Iran. For this study, the parents of these children completed self-administered questionnaires. Results showed that 218 parents (64.1%) agreed with leaving the practice room during their child’s treatment, while 122 (35.9%) did not agree. The main reason expressed by 41.3% of the parents for leaving the practicing room was that the dentist would be better able to control the child if they were alone. Another reason, cited by 16.5% of the parents, was not wanting to see their child suffering, and 42.2% said they believed that their child would be better treated if they were not present. Most parents who were in agreement with leaving the practice room while their child was receiving dental care felt this would lead to a better treatment outcome
