Rural children are more likely to live in cohabiting-couple households
As cohabiting increases nationwide, new data show that the growing rate of children in these households is most pronounced in rural areas. This brief analyzes recent U.S. Census Bureau data to explore these trends and patterns
Kinetic Temperature and Electron Density Measurement in an Inductively Coupled Plasma Torch using Degenerate Four-Wave Mixing
Laser wave mixing is presented as an effective technique for spatially resolved kinetic temperature measurements in an atmospheric-pressure radio-frequency inductively-coupled plasma. Measurements are performed in a 1 kW, 27 MHz RF plasma using a continuous-wave, tunable 811.5-nm diode laser to excite the 4s(sup 3)P2 approaches 4p(sup 3)D3 argon transition. Kinetic temperature measurements are made at five radial steps from the center of the torch and at four different torch heights. The kinetic temperature is determined by measuring simultaneously the line shape of the sub-Doppler backward phase-conjugate degenerate four-wave mixing and the Doppler-broadened forward-scattering degenerate four-wave mixing. The temperature measurements result in a range of 3,500 to 14,000 K+/-150 K. Electron densities measured range from 6.1 (+/-0.3) x 10(exp 15)/cu cm to 10.1 (+/-0.3) x 10(exp 15)/cu cm. The experimental spectra are analyzed using a perturbative treatment of the backward phase-conjugate and forward-geometry wave-mixing theory. Stark width is determined from the collisional broadening measured in the phase-conjugate geometry. Electron density measurements are made based on the Stark width. The kinetic temperature of the plasma was found to be more than halved by adding deionized water through the nebulizer
Water Equity and Security in Detroit's Water and Sewer District
Ensuring access to drinking water and wastewater service is a nationwide policy challenge. Across the United States access is increasingly insecure for many people and places. In this report we comply with scholarship and legal precedent that defines access to include access to residential in-home service, quality service that serves environmental and personal health,and affordable service.Water security is a term in this report used to describe the presence of structural, systemic, and institutional arrangements that ensure everyone has consistent access to drinking water and wastewater services. Water insecurity looks different in the humid east than in the arid west, different in the Midwest from the South, different between urban, suburban, or rural.However different water insecurity problems look at the local level, they are the result of similar institutional, systemic, and structural problems. This is a study of the what persistent water insecurity looks like in the service area of Detroit's drinking and wastewater system (DWSD) and specific places within that system, notably Detroit
Young adults with high autistic-like traits displayed lower food variety and diet quality in childhood
This study explored the association between autistic-like traits in young adults and dietary intake in early childhood in the Gen2 Raine Study cohort. Data were available from 811 participants at years 1, 2 and 3 for the assessment of dietary intake, and at year 20 for measurement of autistic-like traits. Results showed as autistic-like traits increased, total food variety, core food variety and dairy variety decreased (p \u3c 0.05), with a lower consumption of citrus fruits and yoghurt (both p = 0.04). As autistic-like traits increased, diet quality decreased, this trend was significant at 2 years (p = 0.024). Our results suggest that young adults with higher autistic-like traits were more likely to have had lower food variety and diet quality in early childhood
The impact of experiences of ageism on sexual activity and interest in later life
Experiences of ageism are associated with poorer health outcomes. Sexual activity and
interest are areas in life where the impact of ageism may also be evident as popular culture
often depicts the older body as asexual, undesirable or sexually impotent. We explore the
possible links between experiences of ageism and sexual activity/interest in later life using
data from a study of Australians aged 60+. We explored characteristics of those who were
more likely to have experienced ageism (measured using the Ageism survey) and the
relationships between experiences of ageism and measures of sexual interest/activity in later
life (n=1,817). Experiences of ageism were greater among those without a partner,
unemployed participants, those with lower incomes, and poorer self-rated health. Adjusting
for these differences, experiences of ageism were more likely to be reported by those who
had not had sex in the past two years and were not sure about their hopes/plans for sex in the
future. Those who reported their sexual interest had increased or decreased since 60 also
reported greater levels of ageism experience, as did those who wanted to have sex more
frequently in the future. Ageism appears to impact sexual activity and interest in different
ways. It is critical that social policy aims to reverse attitudes that reinforce the view of the
ageist asexual and unattractive older body or person
Does frequent residential mobility in early years affect the uptake and timeliness of routine immunisations? An anonymised cohort study
Background: There are conflicting findings regarding the impact of residential mobility on immunisationstatus. Our aim was to determine whether there was any association between residential mobility andtake up of immunisations and whether they were delayed in administration.
Methods: We carried out a cohort analysis of children born in Wales, UK. Uptake and time of immunisationwere collected electronically. We defined frequent movers as those who had moved: 2 or more times inthe period prior to the final scheduled on-time date (4 months) for 5 in 1 vaccinations; and 3 or moretimes in the period prior to the final scheduled on-time date (12 months) for MMR, pneumococcal andmeningitis C vaccinations. We defined immunisations due at 2–4 months delayed if they had not beengiven by age 1; and those due at 12–13 months as delayed if they had not been given by age 2.
Results: Uptake rates of routine immunisations and whether they were given within the specified time-frame were high for both groups. There was no increased risk (odds ratios (95% confidence intervals)between frequent movers compared to non-movers for the uptake of: primary MMR 1.08 (0.88–1.32);booster Meningitis C 1.65 (0.93–2.92); booster pneumococcal 1.60 (0.59–4.31); primary 5 in 1 1.28(0.92–1.78); and timeliness: primary MMR 0.92 (0.79–1.07); booster Meningitis C 1.26 (0.77–2.07);booster pneumococcal 1.69 (0.23–12.14); and primary 5 in 1 1.04 (0.88–1.23).
Discussion: Findings suggest that children who move home frequently are not adversely affected in termsof the uptake of immunisations and whether they were given within a specified timeframe. Both werehigh and may reflect proactive behaviour in the primary healthcare setting to meet Government coveragerates for immunisation
