Mental Health and Labor Force Exits in Older Workers: The Mediating or Moderating Roles of Physical Health and Job Factors

This paper extends earlier health and work studies by examining how mental health affects transitions out of paid work in the years prior to the traditional Social Security retirement ages. Given recent changes in the labor market, optimal mental health may be as important a prerequisite for continuing employment as good physical health. This study uses data from the Health and Retirement Study to examine how mental health is linked to transitions to early retirement or other unemployment in 1996 for middle-aged adults who were currently working in 1992 and whether physical health, job, or sociodemographic factors affect those links. The study results indicated that mental health plays a strong and significant role in the move from paid work to other unemployment in three ways, net of other documented health, job, and sociodemographic correlates of work status. First, higher baseline CES-D depressive symptoms predicted the transition to retiree in male workers. Second, increased CES-D depressive symptoms between 1992 and 1994 (net of baseline symptoms) predicted exits from paid employment and into other unemployment by 1996. Finally, low job autonomy did not have the hypothesized moderating effect on the mental health-work status link. The results also indicated that mental health may be an even more important predictor of transitions out of paid work among middle-aged workers than are physical health and functioning and that patterns of labor force exit differ for men and women.

Steady and nonsteady supersonic turbulent afterbody flow

The effect of the specific heat ratio gamma of the incoming ideal gas on the flow properties, especially on pressure distributions along the base and sting surfaces and on reattachment distance, was investigated. The specific heat ratios considered were gamma = 1.2, 1.4, and 1.667. Also, effects of other major parameters, such as eddy-viscosity coefficient (or effective Reynolds number) and Mach number, on the afterbody pressure and reattachment distance were studied and are discussed. Evolution of shock induced flow and stabilization time were examined and are discussed for a transient problem. The important influence of the flow-field geometry, pressure distributions, and reattachment distance on the aerodynamics radiative heat transfer for an atmosphere entry probe in high speed flight are briefly described

Census Cities experiment in urban change detection

The author has identified the following significant results. Mapping of 1970 and 1972 land use from high-flight photography has been completed for all test sites: San Francisco, Washington, Phoenix, Tucson, Boston, New Haven, Cedar Rapids, and Pontiac. Area analysis of 1970 and 1972 land use has been completed for each of the mandatory urban areas. All 44 sections of the 1970 land use maps of the San Francisco test site have been officially released through USGS Open File at 1:62,500. Five thousand copies of the Washington one-sheet color 1970 land use map, census tract map, and point line identification map are being printed by USGS Publication Division. ERTS-1 imagery for each of the eight test sites is being received and analyzed. Color infrared photo enlargements at 1:100,000 of ERTS-1 MSS images of Phoenix taken on October 16, 1972 and May 2, 1973 are being analyzed to determine to what level land use and land use changes can be identified and to what extent the ERTS-1 imagery can be used in updating the 1970 aircraft photo-derived land use data base. Work is proceeding on the analysis of ERTS-1 imagery by computer manipulation of ERTS-1 MSS data in digital format. ERTS-1 CCT maps at 1:24,000 are being analyzed for two dates over Washington and Phoenix. Anniversary tape sets have been received at Purdue LARS for some additional urban test sites

A full-scale fire program to evaluate new furnishings and textile materials developed by the National Aeronautics and Space Administration

A program of experimental fires was carried out to establish the advantages offered by new materials for improved fire safety. Four full-scale bedrooms, differing only in the materials used to furnish them, were built and burned to provide comparative data on the fire hazards produced. Cost and availability differences were not considered. The visual evidence provided by TV and photographic coverage of the four experimental room fires showed clearly that the rooms responded very differently to a common ignition condition. Resistance to the ignition and spread of fire was substantially improved in the rooms furnished completely or partially with the new materials

The 'War on Poverty' after 40 Years: A Minskyan Assessment

Hyman Minsky is best known for his work in the area of financial economics, and especially for his financial instability hypothesis. In recent years, some authors have also recognized his advocacy of the “employer of last resort” as part of his “big government” intervention to help maintain stability. However, very little research has been undertaken regarding Minsky’s early involvement in the “War on Poverty.” This paper will trace the development of Minsky’s thinking on antipoverty policies to his support for welfare reform and federal job creation programsWar on Poverty, employer of last resort, anti-poverty programs, Hyman Minsky, unemployment, job creation, welfare, economic opportunity, Keynesian policy, demand stimulus, full employment, structuralist

A systematic experimental investigation of significant parameters affecting model tire hydroplaning

The results of a comprehensive parametric study of model and small pneumatic tires operating on a wet surface are presented. Hydroplaning inception (spin down) and rolling restoration (spin up) are discussed. Conclusions indicate that hydroplaning inception occurs at a speed significantly higher than the rolling restoration speed. Hydroplaning speed increases considerably with tread depth, surface roughness and tire inflation pressure of footprint pressure, and only moderately with increased load. Water film thickness affects spin down speed only slightly. Spin down speed varies inversely as approximately the one-sixth power of film thickness. Empirical equations relating tire inflation pressure, normal load, tire diameter and water film thickness have been generated for various tire tread and surface configurations

Implementation of Directive 2004/38 in the United Kingdom

This article discusses the implementation of Directive 2004/38/EC (the Directive) within the UK’s legal system. After a section which summarises the historical, political and legal context, the article considers firstly the implementing legislation, then administrative practice and, finally, the response of the courts
