Taking Stock of Retirement: How Workers and Employers Assess Pensions, Trust, and the Economy

This survey polls workers and employers regarding their views on corporate scandals and the collapse of Enron, the impact of these events on trust in the workplace, and policy strategies needed to increase pension and retirement security

The Disposable Worker: Living in a Job-Loss Economy

This important survey finds many U.S. workers have experienced job loss and the pinch of economic uncertainty during the 2000-2003 recession. The survey includes a large sample of workers who lost their jobs. The survey shows that many workers were laid off without any advance notice, severance pay, health care coverage, or career counseling. However, large numbers of workers believe these services and benefits are critical to their economic survival. Worker confidence in the U.S. economy and political leadership were at the lowest levels recorded in the history of the then six-year Work Trends series

A Workplace Divided: How Americans View Discrimination and Race on the Job

In this Work Trends survey, American workers express their views on the contentious issue of discrimination in the workplace -- how they perceive and experience discrimination as well as what they expect government and employers to do about it

At a Crossroads: American Workers Assess Jobs and Economic Security Amid the Race for President

New national Work Trends study finds high level of concern about job security, economy, and that citizens are divided on candidates' ability to address their concerns

Lower Bounds of Concurrence for Tripartite Quantum Systems

We derive an analytical lower bound for the concurrence of tripartite quantum mixed states. A functional relation is established relating concurrence and the generalized partial transpositions.Comment: 10 page

Structure and correlation effects in semiconducting SrTiO₃

We have investigated the effects of structure change and electron correlation on SrTiO₃ single crystals using angle-resolved photoemission spectroscopy. We show that the cubic to tetragonal phase transition at 105 K is manifested by a charge transfer from in-plane (dyz and dzx) bands to out-of-plane (dxy) band, which is opposite to the theoretical predictions. Along this second-order phase transition, we find a smooth evolution of the quasiparticle strength and effective masses. The in-plane band exhibits a peak-dip-hump lineshape, indicating a high degree of correlation on a relatively large (170 meV) energy scale, which is attributed to the polaron formation

Wave Profile for Anti-force Waves with Maximum Possible Currents

In the theoretical investigation of the electrical breakdown of a gas, we apply a one-dimensional, steady state, constant velocity, three component fluid model and consider the electrons to be the main element in propagation of the wave. The electron gas temperature, and therefore the electron gas partial pressure, is considered to be large enough to provide the driving force. The wave is considered to have a shock front, followed by a thin dynamical transition region. Our set of electron fluid-dynamical equations consists of the equations of conservation of mass, momentum, and energy, plus the Poisson\u27s equation. The set of equations is referred to as the electron fluid dynamical equations; and a successful solution therefor must meet a set of acceptable physical conditions at the trailing edge of the wave. For breakdown waves with a significant current behind the shock front, modifications must be made to the set of electron fluid dynamical equations, as well as the shock condition on electron temperature. Considering existence of current behind the shock front, we have derived the shock condition on electron temperature, and for a set of experimentally measured wave speeds, we have been able to find maximum current values for which solutions to our set of electron velocity, electron temperature, and electron number density within the dynamical transition region of the wave
