    Patterned Responses to Organizing: Case Studies of the Union-Busting Convention

    [Excerpt] In June 1993, the Industrial Union Department (IUD) of the AFL-CIO initiated a project to gather cases from affiliated unions that would highlight aspects of the National Labor Relations Board process deserving attention from those shaping labor law reform proposals. Based on the cases submitted, we conclude that in its current form the National Labor Relations Act serves to impede union organizing. Particularly problematic are NLRB policies that allow employers to wage no-holds-barred antiunion campaigns. Even where there are legal restrictions on specific actions, the penalties for violations are so meager that they serve no deterrent effect. The cases described below cover many industries, all parts of the country, large units and small, and collectively suggest that union busting has become the convention among U.S. employers

    The Economic Status of the Elderly

    In the first part of the paper using official data sources, we estimate the real income of the elderly and of the rest of the population during the 1570s. We find that income per household of the elderly has increased more rapidly than income per household of the rest of the population, even though the elderly's fraction of income from work decreased greatly. In the rest of the paper we use the 1969 and 1975 Retirement History Surveys to estimate income, wealth and inflation vulnerability of households whose heads were ages 58 through 63 in 1969. The income data verified the results from the official data. The 1969 wealth data show that a representative person on the eve of retirement has small holdings of financial assets: most of the assets are in housing, Social Security and Medicare. Between 1969 and 1975 real wealth increased slightly on average. There was some tendency for the distribution to tighten. We found that contrary to popular opinion, on average the elderly are not especially vulnerable to a sudden increase in either prices or the rate of inflation. Most of their assets are inflation protected. The wealthy are most vulnerable to inflation.

    The Distributional Impact of Social Security

    In the first part of the paper we report estimated transfers in the Social Security system for the Retirement History Survey sample.We define transfers to be the difference between the expected presentvalue of benefits less the present value of taxes paid in, where the latter is adjusted for the probability of living to reach retirement age.Unlike previous researchers we, therefore, account for the taxes paid by people who died before retirement, and it turns out this adjustment is important for some groups. The Retirement History Survey cohort will receive large transfers: roughly benefits will be about four times taxes,and the real internal rate of return will be about eight percent. We study how transfers vary by a comprehensive measure of wealth. People in the highest wealth quartile have the largest absolute transfers, and their internal rate of return is as high as that of any wealth quartile.In the second part of the paper we study transfers forsix synthetic cohorts, the heads of which are age 65 in the ten-year intervals 1970 through 2020. Within each cohort 12 families are defined according to earnings levels.We find that transfers are positive and large for the 1970 cohort, and that they decline steadily until they are negative for most groups in the 2020 cohort. Although high earners initially have the largest transfers in the 1970 cohort, they have the largest negative transfers in the 2020 cohort.

    Anomalous Fermi Liquid Behavior of Overdoped High-Tc Superconductors

    According to a generic temperature vs. carrier-doping (T-p) phase diagram of high-temperature superconductors it has been proposed that as doping increases to the overdoped region they approach gradually a conventional (canonical) Fermi Liquid. However, Hall effect measurements in several systems reported by different authors show a still strong \emph{T}-dependence in overdoped samples. We report here electrical transport measurements of Y_{1-x}Ca_{x}Ba_{2}Cu_{3}O_{7-delta} thin films presenting a temperature dependence of the Hall constant, R_H, which does not present a gradual transition towards the T-independent behavior of a canonical Fermi Liquid. Instead, the T-dependence passes by a minimum near optimal doping and then increases again in the overdoped region. We discuss the theoretical predictions from two representative Fermi Liquid models and show that they can not give a satisfactory explanation to our data. We conclude that this region of the phase diagram in YBCO, as in most HTSC, is not a canonical Fermi Liquid, therefore we call it Anomalous Fermi Liquid.Comment: 9 pages, 12 figures, to be published in Phys.

    System for the measurement of ultra-low stray light levels

    An apparatus is described for measuring the effectiveness of stray light suppression light shields and baffle arrangements used in optical space experiments and large space telescopes. The light shield and baffle arrangement and a telescope model are contained in a vacuum chamber. A source of short, high-powered light energy illuminates portions of the light shield and baffle arrangement and reflects a portion of same to a photomultiplier tube by virtue of multipath scattering. The resulting signal is transferred to time-channel electronics timed by the firing of the high energy light source allowing time discrimination of the signal thereby enabling the light scattered and suppressed by the model to be distinguished from the walls and holders around the apparatus

    Intercontinental antenna arraying by symbol stream combining at ICE Giacobini-Zinner encounter

    Get PDF
    Deep space tracking stations on different continents were arrayed during the encounter of the International Cometary Explorer (ICE) spacecraft with the comet Giacobini-Zinner during September 9 through 12, 1985. This is the first time that telemetry signals received on different continents have been combined to enhance signal to noise ratio. The arraying was done in non-real time using the method of symbol stream combining. The improvement in signal to noise ratio was typically 2 dB over the stronger of the two stations in each array
