Saving and Asset Accumulation Among Low-Income Families With Children in IDAs
Research indicates that low-income families with children have many motives to save, however, the costs of raising children, low wage employment, means tested programs, and the need for child care make it difficult for them to save. Using data from the American Dream Demonstration (n=1,801), this study examines saving performances of low-income families with children in a matched savings program – Individual Development Accounts (IDAs). The results indicate that households with children in IDAs can save when they are provided structured opportunities. In addition, this study finds that institutional factors, not merely individual characteristics, are highly associated with IDA saving performance, and are important in explaining saving performances in IDAs. Implications for policy makers and program administrators to better assist low – income families to save and accumulate assets in IDAs are given
A Savings Account for Every Child Born in Israel: Recommendations for Program Implementation
In November 2015, Israel enacted legislation to create and fund a Child Development Account program. Beginning in 2017, every baby born to an insured Israeli resident will receive a Child Development Account in his or her name. This brief details the policy, which was developed in collaboration with researchers at the Center for Social Development, and offers recommendations to guide its implementation

Effects of an Individual Development Account Program on Retirement Saving: Follow-Up Evidence From a Randomized Experiment
Using data from a randomized experiment that ran from 1998 to 2003 in Tulsa, Oklahoma, we examine the 10-year follow-up effects on retirement saving of an Individual Development Account (IDA) program. The IDA program included financial education, encouragement to save, and matching funds for several qualified uses of the savings, including contributions to retirement accounts. The results indicate that, as of 2009, 6 years after the program ended, the IDA program had no impact on the propensity to hold a retirement account, the account balance, or the sufficiency of retirement balances to meet retirement expenses
Individual Development Accounts and Post-Secondary Education: Evidence From a Randomized Experiment
This paper presents evidence from a randomized field experiment testing the impact of a 3-year matched savings program on educational outcomes 10 years later. We examine the effect of an Individual Development Account (IDA) program on educational enrollment, degree completion, and increased education level. The IDA program, which ran from 1998 to 2003 in Tulsa, Oklahoma, provided low-income households with financial education and matching funds for qualified savings withdrawals, including a 1:1 match for educational uses. We find a significant impact on education enrollment and positive, but non-significant impacts on degree completion and increase in level of education. We also examine the interaction between gender and treatment assignment and find that the IDA had a strong positive effect on increased educational attainment for males, but not for females
Quantum thermodynamics of a charged magneto-oscillator coupled to a heat bath
Explicit results for various quantum thermodynamic function (QTF) of a
charged magneto-oscillator coupled to a heat bath at arbitrary temperature are
demonstrated in this paper. Discernible expressions for different QTF in the
two limits of very low and very high temperatures are presented for three
popular heat bath models : Ohmic, single relaxation time and blackbody
radiation. The central result is that the effect of magnetic field turns out to
be important at low temperatures yet crucial at high temperatures. It is
observed that the dissipation parameter, , and the cyclotron frequency,
, affect the decaying or rising behaviour of various QTF in just the
opposite way to each other at low temperatures. In the high temperature regime,
the effect of is much pronounced than that of .Comment: 26 Pages, 18 Figure
International Child Development Accounts
This Working Paper has been submitted for inclusion in the new online edition of theEncyclopedia of Social Work, which is published by Oxford University Press. The paper discusses efforts to implement Child Development Accounts in the United States and numerous other countries. Child Development Accounts (CDAs) are subsidized savings or investment accounts to help people accumulate assets for developmental purposes and life course needs. They are envisioned as universal (everyone participates), progressive (greater subsidies for the poor), and potentially lifelong national policy. These features distinguish CDAs from most existing asset-building policies and programs around the world, which are typically regressive, giving greater benefits to the well-off. With policy innovation in recent years, several countries now have national CDA policies, and four states in the United States have statewide programs. Some of these are designed to be universal and progressive. Evidence indicates that true universality can be achieved, but only with automatic account opening and automatic deposits. In the absence of automatic features, advantaged families participate and benefit more. Today, momentum for universal and automatic features is gradually gaining traction and accelerating. At this stage in the emergence of inclusive asset-based policy, this is the most important development
Rare region effects at classical, quantum, and non-equilibrium phase transitions
Rare regions, i.e., rare large spatial disorder fluctuations, can
dramatically change the properties of a phase transition in a quenched
disordered system. In generic classical equilibrium systems, they lead to an
essential singularity, the so-called Griffiths singularity, of the free energy
in the vicinity of the phase transition. Stronger effects can be observed at
zero-temperature quantum phase transitions, at nonequilibrium phase
transitions, and in systems with correlated disorder. In some cases, rare
regions can actually completely destroy the sharp phase transition by smearing.
This topical review presents a unifying framework for rare region effects at
weakly disordered classical, quantum, and nonequilibrium phase transitions
based on the effective dimensionality of the rare regions. Explicit examples
include disordered classical Ising and Heisenberg models, insulating and
metallic random quantum magnets, and the disordered contact process.Comment: Topical review, 68 pages, 14 figures, final version as publishe
Explorative data analysis of MCL reveals gene expression networks implicated in survival and prognosis supported by explorative CGH analysis
<p>Abstract</p> <p>Background</p> <p>Mantle cell lymphoma (MCL) is an incurable B cell lymphoma and accounts for 6% of all non-Hodgkin's lymphomas. On the genetic level, MCL is characterized by the hallmark translocation t(11;14) that is present in most cases with few exceptions. Both gene expression and comparative genomic hybridization (CGH) data vary considerably between patients with implications for their prognosis.</p> <p>Methods</p> <p>We compare patients over and below the median of survival. Exploratory principal component analysis of gene expression data showed that the second principal component correlates well with patient survival. Explorative analysis of CGH data shows the same correlation.</p> <p>Results</p> <p>On chromosome 7 and 9 specific genes and bands are delineated which improve prognosis prediction independent of the previously described proliferation signature. We identify a compact survival predictor of seven genes for MCL patients. After extensive re-annotation using GEPAT, we established protein networks correlating with prognosis. Well known genes (CDC2, CCND1) and further proliferation markers (WEE1, CDC25, aurora kinases, BUB1, PCNA, E2F1) form a tight interaction network, but also non-proliferative genes (SOCS1, TUBA1B CEBPB) are shown to be associated with prognosis. Furthermore we show that aggressive MCL implicates a gene network shift to higher expressed genes in late cell cycle states and refine the set of non-proliferative genes implicated with bad prognosis in MCL.</p> <p>Conclusion</p> <p>The results from explorative data analysis of gene expression and CGH data are complementary to each other. Including further tests such as Wilcoxon rank test we point both to proliferative and non-proliferative gene networks implicated in inferior prognosis of MCL and identify suitable markers both in gene expression and CGH data.</p
A Next-Generation Liquid Xenon Observatory for Dark Matter and Neutrino Physics
The nature of dark matter and properties of neutrinos are among the mostpressing issues in contemporary particle physics. The dual-phase xenontime-projection chamber is the leading technology to cover the availableparameter space for Weakly Interacting Massive Particles (WIMPs), whilefeaturing extensive sensitivity to many alternative dark matter candidates.These detectors can also study neutrinos through neutrinoless double-beta decayand through a variety of astrophysical sources. A next-generation xenon-baseddetector will therefore be a true multi-purpose observatory to significantlyadvance particle physics, nuclear physics, astrophysics, solar physics, andcosmology. This review article presents the science cases for such a detector.<br
