Perceived Impact of Individual Development Account Participation Among Native Hawaiians

Indigenous peoples face many social development challenges and the lingering effects of colonization. Income transfer, a traditional social welfare approach designed to raise minimum living standards, has had limited beneficial effects on long-term social conditions. As a complement to income transfer, asset-based approaches to social welfare have resulted in positive effects in the short and long terms. Some Indigenous communities are exploring how asset-based interventions might enhance social development (Hicks, Edwards, Dennis, & Finsel, 2005), but only limited and scattered research describes how they experience asset-building programs. This qualitative descriptive study explores the perceived impact of a large Individual Development Account (IDA) program for Indigenous Native Hawaiians. Data consist of answers to open-ended questions about the impacts of participating in an IDA program. Participants felt that the culturally based program material was empowering and that they gained lasting, meaningful life skills. They attributed skills development, psychological changes, and tangible asset gains to the IDA program. Notably, participants who did not finish the program identified barriers to doing so, including a lack of flexibility in savings requirements and life events that forced an exit from the program

Effects of sex chromosome dosage on corpus callosum morphology in supernumerary sex chromosome aneuploidies.

BackgroundSupernumerary sex chromosome aneuploidies (sSCA) are characterized by the presence of one or more additional sex chromosomes in an individual's karyotype; they affect around 1 in 400 individuals. Although there is high variability, each sSCA subtype has a characteristic set of cognitive and physical phenotypes. Here, we investigated the differences in the morphometry of the human corpus callosum (CC) between sex-matched controls 46,XY (N =99), 46,XX (N =93), and six unique sSCA karyotypes: 47,XYY (N =29), 47,XXY (N =58), 48,XXYY (N =20), 47,XXX (N =30), 48,XXXY (N =5), and 49,XXXXY (N =6).MethodsWe investigated CC morphometry using local and global area, local curvature of the CC boundary, and between-landmark distance analysis (BLDA). We hypothesized that CC morphometry would vary differentially along a proposed spectrum of Y:X chromosome ratio with supernumerary Y karyotypes having the largest CC areas and supernumerary X karyotypes having significantly smaller CC areas. To investigate this, we defined an sSCA spectrum based on a descending Y:X karyotype ratio: 47,XYY, 46,XY, 48,XXYY, 47,XXY, 48,XXXY, 49,XXXXY, 46,XX, 47,XXX. We similarly explored the effects of both X and Y chromosome numbers within sex. Results of shape-based metrics were analyzed using permutation tests consisting of 5,000 iterations.ResultsSeveral subregional areas, local curvature, and BLDs differed between groups. Moderate associations were found between area and curvature in relation to the spectrum and X and Y chromosome counts. BLD was strongly associated with X chromosome count in both male and female groups.ConclusionsOur results suggest that X- and Y-linked genes have differential effects on CC morphometry. To our knowledge, this is the first study to compare CC morphometry across these extremely rare groups

Does Medicaid Make a Difference? Findings from the Commonwealth Fund Biennial Health Insurance Survey, 2014

As millions of Americans gain Medicaid coverage under the Affordable Care Act, attention has focused on the access to care, quality of care, and financial protection that coverage provides. This analysis uses the Commonwealth Fund Biennial Health Insurance Survey, 2014, to explore these questions by comparing the experiences of working-age adults with private insurance who were insured all year, Medicaid beneficiaries with a full year of coverage, and those who were uninsured for some time during the year. The survey findings suggest that Medicaid coverage provides access to care that in most aspects is comparable to private insurance. Adults with Medicaid coverage reported better care experiences on most measures than those who had been uninsured during the year. Medicaid beneficiaries also seem better protected from the cost of illness than do uninsured adults, as well as those with private coverage

Chip-Scale, Sub-Hz Fundamental Sub-kHz Integral Linewidth 780 nm Laser through Self-Injection-Locking a Fabry-P\'erot laser to an Ultra-High Q Integrated Resonator

Today's state of the art precision experiments in quantum, gravimetry, navigation, time keeping, and fundamental science have strict requirements on the level and spectral distribution of laser frequency noise. For example, the laser interaction with atoms and qubits requires ultra-low frequency noise at multiple offset frequencies due to hyperfine atomic transitions, motional sidebands, and fast pulse sequencing. Chip-scale integration of lasers that meet these requirements is essential for reliability, low-cost, and weight. Here, we demonstrate a significant advancement in atomic precision light sources by realizing a chip-scale, low-cost, 780 nm laser for rubidium atom applications with record-low 640 mHz (white noise floor at 0.2 Hz$^2$/Hz) fundamental and 732 Hz integral linewidths and a frequency noise that is multiple orders of magnitude lower than previous hybrid and heterogeneous self-injection locked 780 nm lasers and lower noise than bulk microresonator implementations. The laser is a Fabry-P\'erot laser diode self-injection locked to an ultra-high Q photonic integrated silicon nitride resonator. This performance is enabled by a 145 million resonator Q with a 30 dB extinction ratio, the highest Q at 780 nm, to the best of our knowledge. We analyze the impact of our frequency noise on specific atomic applications including atomic frequency references, Rydberg quantum gates, and cold atom gravimeters. The photonic integrated resonator is fabricated using a CMOS foundry-compatible, wafer-scale process, with demonstrated integration of other components showing promise for a full system-on-a-chip. This performance is scalable to other visible atomic wavelengths, opening the door to a variety of transitions across many atomic species and enabling low-power, compact, ultra-low noise lasers impacting applications including quantum sensing, computing, clocks and more

Algebras generated by two bounded holomorphic functions

We study the closure in the Hardy space or the disk algebra of algebras generated by two bounded functions, of which one is a finite Blaschke product. We give necessary and sufficient conditions for density or finite codimension of such algebras. The conditions are expressed in terms of the inner part of a function which is explicitly derived from each pair of generators. Our results are based on identifying z-invariant subspaces included in the closure of the algebra. Versions of these results for the case of the disk algebra are given.Comment: 22 pages ; a number of minor mistakes have been corrected, and some points clarified.

Single-parameter non-adiabatic quantized charge pumping

Controlled charge pumping in an AlGaAs/GaAs gated nanowire by single-parameter modulation is studied experimentally and theoretically. Transfer of integral multiples of the elementary charge per modulation cycle is clearly demonstrated. A simple theoretical model shows that such a quantized current can be generated via loading and unloading of a dynamic quasi-bound state. It demonstrates that non-adiabatic blockade of unwanted tunnel events can obliterate the requirement of having at least two phase-shifted periodic signals to realize quantized pumping. The simple configuration without multiple pumping signals might find wide application in metrological experiments and quantum electronics.Comment: 4 pages, 4 figure

Americans' Experiences in the Health Insurance Marketplaces: Results from The First Three Months

Conducted December 11–29, 2013, The Commonwealth Fund's second Affordable Care Act Tracking Survey interviewed a nationally representative sample of adults who are potentially eligible for the health reform law's new insurance options, whether private plans or Medicaid. Results show that by the end of December, 24 percent of potentially eligible adults had visited a marketplace to find a plan. The first survey, conducted in October, had found that 17 percent of people potentially eligible for coverage had visited the marketplaces during the first month of open enrollment. By the end of December, 41 percent of visitors were ages 19 to 34, and 77 percent reported being in good health. People's ability to compare benefits and premiums improved between October and December, but many reported challenges in plan selection. A majority of respondents say they are determined to gain coverage by the end of this year's open enrollment period
