What the 2008 Stock Market Crash Means for Retirement Security
Compares future retirement resources before and after the stock market decline, by gender, marital status, race/ethnicity, education, and retirement income quintile, under three scenarios: no recovery, full recovery, and partial recovery in ten years
The Potential Impact of the Great Recession on Future Retirement Incomes
Estimates the effects of job loss, slower wage growth, and withdrawals from retirement savings during the 2007-09 recession on retirement incomes at age 70, including decline in income by age group and number of those likely to live in poverty at 70
Evolution of a Field Biologist
In My Double Life, biologist Frances Hamerstrom reveals her evolution from an affluent childhood in early 1900s Boston to a rugged and spirited field biologist. She writes in first person with short, easy-reading chapters about her life, generally in chronological order from childhood to present. The anecdotes are concise, witty, and spiced with humor in her characteristic, blissful confidence. There are many unique black-and-white photographs reproduced, as well as pen-and-ink illustrations mostly by her artist-daughter, Elva Hamerstrom Paulson. Half of the book\u27s chapters are borrowed from earlier works, in particular her award-winning Strictly for the Chickens (1980). This new book complements several more-or-Iess autobiographic works by presenting Hamerstrom\u27s childhood adventures and exploits. Toward its closing, the book finds her in her mid-80s exploring primitive worlds by travelling with Pygmies and Indians in Africa and South America
A Climatology of Tropospheric Zonal-Mean Water Vapor Fields and Fluxes in Isentropic Coordinates
Based on reanalysis data for the years 1980–2001 from the European Centre for Medium-Range Weather Forecasts (ERA-40 data), a climatology of tropospheric zonal-mean water vapor fields and fluxes in isentropic coordinates is presented. In the extratropical free troposphere, eddy fluxes dominate the meridional flux of specific humidity along isentropes. At all levels, isentropic eddy fluxes transport water vapor from the deep Tropics through the subtropics into the extratropics. Isentropic eddy fluxes of specific humidity diverge near the surface and in the tropical and subtropical free troposphere; they converge in the extratropical free troposphere. Isentropic mean advective fluxes of specific humidity play a secondary role in the meridional water vapor transport in the free troposphere; however, they dominate the meridional flux of specific humidity near the surface, where they transport water vapor equatorward and, in the solstice seasons, across the equator. Cross-isentropic mean advective fluxes of specific humidity are especially important in the Hadley circulation, in whose ascending branches they moisten and in whose descending branches they dry the free troposphere.
Near the minima of zonal-mean relative humidity in the subtropical free troposphere, the divergence of the cross-isentropic mean advective flux of specific humidity in the descending branches of the Hadley circulation is the dominant divergence in the mean specific humidity balance; it is primarily balanced by convergence of cross-isentropic turbulent fluxes that transport water vapor from the surface upward. Although there are significant isentropic eddy fluxes of specific humidity through the region of the subtropical relative humidity minima, their divergence near the minima is generally small compared with the divergence of cross-isentropic mean advective fluxes, implying that moistening by eddy transport from the Tropics into the region of the minima approximately balances drying by eddy transport into the extratropics. That drying by cross-isentropic mean subsidence near the subtropical relative humidity minima is primarily balanced by moistening by upward turbulent fluxes of specific humidity, likely in convective clouds, suggests cloud dynamics may play a central role in controlling the relative humidity of the subtropical free troposphere
"Working for a Good Retirement"
The choice of retirement age is the most important portfolio choice most workers will make. Drawing on the Urban Institute's Dynamic Simulation of Income model (DYNASIM3), this report examines how delaying retirement for nondisabled workers would affect individual retiree benefits, the solvency of the Social Security trust fund, and general revenues. The results suggest that delaying retirement by itself does not generate enough additional revenue to make Social Security solvent by 2045. Benefit cuts or supplementary funding sources will be necessary to achieve solvency. However, the size of the benefit cuts or tax increases could be minimized if individuals worked longer. This additional work also substantially increases worker's retirement well-being. Lower-income workers, to the extent they can work longer, have the most to gain from their additional labor. Policy changes that encourage work at older ages will substantially improve both economic and personal well-being in the future.
Teachers Are Making a Difference: Understanding the Influence of Favorite Teachers
Using the theoretical framework of occupational socialization, the purpose of this study was to examine preservice physical education teachers’ beliefs and values of teachers and teaching through analysis and interpretation of favorite teacher narratives. One hundred and eighty six preservice physical education teachers’ narratives were collected and analyzed using open and axial coding (Corbin & Strauss, 2008). The qualities and characteristics identified through analysis were organized into seven inclusive sub-categories of favorite teacher characteristics and abilities and were articulated into three central themes, described as Pay it Forward, Caring in Teaching, and Motivated to Learn. The findings suggest that understanding favorite teacher influences on preservice teachers provides insights into maximizing the impact of physical education teacher education programs
Overview of Instruments of Measurement for Perceived Discrimination
The purpose of this study is to examine the current tools of measurement for perceived discrimination. Specifically, to investigate the number of tools of measurement available, similarities and differences between different tools available, and possible gaps in these tools of measurement. Literature shows the impact of perceived discrimination on both physical and mental health, but little literature exists on the quality and quantity of tools of measurement for perceived discrimination. By investigating current tools of measurement improvements may be made in the collection and analysis of such data
Segmental Kinematic Analysis of Planovalgus Feet during Walking in Children with Cerebral Palsy
Pes planovalgus (flatfoot) is a common deformity among children with cerebral palsy. The Milwaukee Foot Model (MFM), a multi-segmental kinematic foot model, which uses radiography to align the underlying bony anatomy with reflective surface markers, was used to evaluate 20 pediatric participants (30 feet) with planovalgus secondary to cerebral palsy prior to surgery. Three-dimensional kinematics of the tibia, hindfoot, forefoot, and hallux segments are reported and compared to an age-matched control set of typically-developing children. Most results were consistent with known characteristics of the deformity and showed decreased plantar flexion of the forefoot relative to hindfoot, increased forefoot abduction, and decreased ranges of motion during push-off in the planovalgus group. Interestingly, while forefoot characteristics were uniformly distributed in a common direction in the transverse plane, there was marked variability of forefoot and hindfoot coronal plane and hindfoot transverse plane positioning. The key finding of these data was the radiographic indexing of the MFM was able to show flat feet in cerebral palsy do not always demonstrate more hindfoot eversion than the typically-developing hindfoot. The coronal plane kinematics of the hindfoot show cases planovalgus feet with the hindfoot in inversion, eversion, and neutral. Along with other metrics, the MFM can be a valuable tool for monitoring kinematic deformity, facilitating clinical decision making, and providing a quantitative analysis of surgical effects on the planovalgus foot
