2005 California Health Interview Survey

Presents survey results on the health conditions and needs, health behaviors, and sources of medical care of adults, adolescents, and children in California. Analyzes data by demographics, income, and insurance status and highlights changes from 2003

Families with Young Children in California: Findings from the California Health Interview Survey, 2011-2014, by Geography and Home Language.

Using data from the California Health Interview Survey (CHIS) for the years 2011-2014, this report presents findings on families with children ages 0-5 years. It breaks down differences between urban, suburban, and rural families, and it highlights the characteristics of families who speak a language other than English in the home. As more than half of families with young children in California speak a language other than English in the home, the characteristics of dual language households are highlighted. In 1998, California passed the California Children and Families Act to improve development for children from the prenatal stage to five years of age. One goal of this ongoing commitment is to expand our understanding of the social and physical environments that can impact a child’s well-being and school readiness

Health of California's Adults, Adolescents and Children: Findings from the CHIS 2003 and CHIS 2001

Many Californians are still struggling to reach good health, according to this report from the California Health Interview Survey (CHIS), the country's largest population-based state health survey. Entitled "Health of California's Adults, Adolescents and Children: Findings from CHIS 2003 and CHIS 2001," the new report illustrates that while half of the state's adults and adolescents report their health was "very good" or "excellent," more than one in five describe their health as "fair" or "poor." Other measures from the survey show that millions of Californians suffer the effects of ill health, limited access to health care and chronic disease. The report includes new data from CHIS 2003 on a variety of health topics -- including health conditions and limitations, health behaviors, insurance and access to care among many others -- and highlights significant changes from CHIS 2001. The report also details California's progress in achieve the healthy People 2010 objectives, a set of national health objectives created to encourage progress in the nation’s health along key health measures

Health Profile of California's Adolescents: Findings from the 2001 California Health Interview Survey

This report presents information about the health of California’s adolescents, ranging from contextual factors – such as adult supervision and parental monitoring – to specific adolescent health behaviors, and their access and utilization of health care. Together, this information provides a comprehensive look at key issues that influence adolescent health and the subsequent health of adults. We begin with background information about the California Health Interview Survey (CHIS). We then discuss findings from CHIS 2001 in our major topic areas: adult supervision and parental monitoring; risky and protective behaviors; and health care access and utilization. We conclude with policy implications. For each of these major topic areas, we highlight significant disparities among different groups of adolescents, including differences by gender, income and race/ethnicity. These disparities are important to note because, although often interrelated, race/ethnicity and income exert independent influences on adolescent health measures.6, 7 Reflecting the important changes that accompany adolescent development, data are also presented by age, differentiating younger (ages 12-14) from older adolescents (ages 15-17)

Magnetic stability of oxygen defects on the SiO2 surface

The magnetic stability of E' centers and the peroxy radical on the surface of alpha-quartz is investigated with first-principles calculations to understand their role in magnetic flux noise in superconducting qubits (SQs) and superconducting quantum interference devices (SQUIDs) fabricated on amorphous silica substrates. Paramagnetic E' centers are common in both stoichiometric and oxygen deficient silica and quartz, and we calculate that they are more common on the surface than the bulk. However, we find the surface defects are magnetically stable in their paramagnetic ground state and thus will not contribute to 1/f noise through fluctuation at millikelvin temperatures.112sciescopu

Coronal Heating as Determined by the Solar Flare Frequency Distribution Obtained by Aggregating Case Studies

Flare frequency distributions represent a key approach to addressing one of the largest problems in solar and stellar physics: determining the mechanism that counter-intuitively heats coronae to temperatures that are orders of magnitude hotter than the corresponding photospheres. It is widely accepted that the magnetic field is responsible for the heating, but there are two competing mechanisms that could explain it: nanoflares or Alfv\'en waves. To date, neither can be directly observed. Nanoflares are, by definition, extremely small, but their aggregate energy release could represent a substantial heating mechanism, presuming they are sufficiently abundant. One way to test this presumption is via the flare frequency distribution, which describes how often flares of various energies occur. If the slope of the power law fitting the flare frequency distribution is above a critical threshold, $\alpha=2$ as established in prior literature, then there should be a sufficient abundance of nanoflares to explain coronal heating. We performed $>$600 case studies of solar flares, made possible by an unprecedented number of data analysts via three semesters of an undergraduate physics laboratory course. This allowed us to include two crucial, but nontrivial, analysis methods: pre-flare baseline subtraction and computation of the flare energy, which requires determining flare start and stop times. We aggregated the results of these analyses into a statistical study to determine that $\alpha = 1.63 \pm 0.03$. This is below the critical threshold, suggesting that Alfv\'en waves are an important driver of coronal heating.Comment: 1,002 authors, 14 pages, 4 figures, 3 tables, published by The Astrophysical Journal on 2023-05-09, volume 948, page 7
