Job-based Coverage Drops for Adults and Children but Public Programs Boost Children's Coverage
Provides a profile of non-elderly Californians' health insurance coverage and lack of coverage, and describes how these rates have changed. Estimates the number of children and adults who are uninsured but eligible for coverage through public programs
12-Month Continuous Eligibility in Medicaid: Impact on Service Utilization
Summarizes findings on how allowing Medicaid enrollees to remain enrolled without reapplying for twelve months affected the number of Medi-Cal-enrolled children's emergency room visits and physician visits compared with those with discontinuous coverage
Number of Uninsured Jumped to More Than Eight Million from 2007 to 2009
Updates 2007 California Health Interview Survey data with estimates for 2009 population growth and changes in insurance status among the non-elderly. Examines trends by source of coverage and explores contributing factors

Nearly 6.4 Million Californians Lacked Health Insurance in 2007 -- Recession Likely to Reverse Small Gains in Coverage
Summarizes findings from the California Health Interview Survey (CHIS) on trends in the state's uninsured rate, the underlying factors, and projected trends. Points to flaws in the eligibility rules for public coverage and outlines policy implications
Age-related shifts in bacterial diversity in a reef coral
This study investigated the relationship between microbial communities in differently sized colonies of the massive coral Coelastrea aspera at Phuket, Thailand where colony size could be used as a proxy for age. Results indicated significant differences between the bacterial diversity (ANOSIM, R = 0.76, p = 0.001) of differently sized colonies from the same intertidal reef habitat. Juvenile and small colonies (28 cm mean diam). Bacterial diversity increased in a step-wise pattern from juvenilessmallmedium colonies, which was then followed by a slight decrease in the two largest size classes. These changes appear to resemble a successional process which occurs over time, similar to that observed in the ageing human gut. Furthermore, the dominant bacterial ribotypes present in the tissues of medium and large sized colonies of C. aspera, (such as Halomicronema, an Oscillospira and an unidentified cyanobacterium) were also the dominant ribotypes found within the endolithic algal band of the coral skeleton; a result providing some support for the hypothesis that the endolithic algae of corals may directly influence the bacterial community present in coral tissues.Barbara Brown recieved funding from the Leverhulme Trust [www.leverhulme.ac.uk]; Grant number: EM-2013-058.

The Absolute Magnitude Distribution of Kuiper Belt Objects
Here we measure the absolute magnitude distributions (H-distribution) of the
dynamically excited and quiescent (hot and cold) Kuiper Belt objects (KBOs),
and test if they share the same H-distribution as the Jupiter Trojans. From a
compilation of all useable ecliptic surveys, we find that the KBO
H-distributions are well described by broken power-laws. The cold population
has a bright-end slope, , and break
magnitude, (r'-band). The hot population has
a shallower bright-end slope of, , and
break magnitude . Both populations share
similar faint end slopes of . We estimate the masses of the
hot and cold populations are and \sim3\times10^{-4} \mbox{
M_{\bigoplus}}. The broken power-law fit to the Trojan H-distribution has
, , and
. The KS test reveals that the probability that the Trojans
and cold KBOs share the same parent H-distribution is less than 1 in 1000. When
the bimodal albedo distribution of the hot objects is accounted for, there is
no evidence that the H-distributions of the Trojans and hot KBOs differ. Our
findings are in agreement with the predictions of the Nice model in terms of
both mass and H-distribution of the hot and Trojan populations. Wide field
survey data suggest that the brightest few hot objects, with
, do not fall on the steep power-law slope of fainter
hot objects. Under the standard hierarchical model of planetesimal formation,
it is difficult to account for the similar break diameters of the hot and cold
populations given the low mass of the cold belt.Comment: Accepted to the Astrophysical Journa
The State of Health Insurance in California: Findings From the 2003 California Health Interview Survey
Provides an overview of the shift from job-based health insurance to enrollment in public insurance programs, and discusses the advantages and disadvantages of key public policy options to extend coverage to California's uninsured residents
