What Workers Want

[Excerpt] This updated edition of What Workers Want keeps the core text and chapter structure of the first edition (Chapters 1-7 in the current book), while eliminating its appendices. The appendices reported the methodology, telephone questionnaires, and written materials used in the two waves of the Worker Representation and Participation Survey (WRPS), all of which is no available online at www.nber.org/~freeman/wrps.html. That site also offers an integrated dataset of all findings, ready for download by interested researchers, and links to other national surveys, modeled on the WRPS, conducted since. New to the updated edition are a new introduction and conclusion. The Introduction examines how our original findings stand up in light of the survey research that others have done since the WRPS. The Conclusion offers suggestions on how to reform our labor relations system so that it delivers to workers what they want in the form of workplace representation and participation

Federal Criminal Procedure-Collateral Relief Under 28 U.S.C. Section 2255- Discretion of Sentencing Court to Dismiss Successive Application Without Hearing

Prisoner, sentenced by a United States district court, filed two successive motions to vacate his sentence under 28 U.S.C. section 2255, which provides for a compulsory motion procedure for federal prisoners in lieu of habeas corpus. Under this section, a prisoner is required to petition the court which sentenced him in order to test the legality of his detention. The motion must be given a prompt hearing, unless the motion and the files and records of the case conclusively show that the prisoner is entitled to no relief. .. If a successive motion is filed for similar relief the sentencing court may properly dismiss the motion without a hearing. Both of prisoner\u27s motions were denied by the sentencing court without hearing, although the second motion alleged a new factual ground which, if substantiated, would have entitled him to relief. The court of appeals affirmed, holding that the second motion, even though supported by a new ground, was a motion for similar relief under section 2255, which the sentencing court may dismiss without hearing. On certiorari, held, reversed, two Justices dissenting. A successive motion is for similar relief only when the same ground was decided against petitioner on the merits in a prior proceeding. Sanders v. United States, 373 U.S. 1 (1963)

Public Control of Private Sectarian Institutions Receiving Public Funds

This comment will examine the recent judicial and legislative developments which could result in federal controls limiting religious practices in private sectarian educational and welfare institutions

Summary Report of mission acceleration measurements for STS-66. Launched November 3, 1994

Experiments flown in the middeck of Atlantis during the STS-66 mission were supported by the Space Acceleration Measurement System (SAMS). In particular, the three triaxial SAMS sensor heads collected data in support of protein crystal growth experiments. Data collected during STS-66 are reviewed in this report. The STS-66 SAMS data represent the microgravity environment in the 0.01 Hz to 10 Hz range. Variations in the environment related to differing levels of crew activity are discussed in the report. A comparison is made among times when the crew was quiet during a public affairs conference, working quietly, and exercising. These levels of activity are also compared to levels recorded by a SAMS unit in the Spacelab on Columbia during the STS-65 mission

Summary Report of Mission Acceleration Measurements for STS-62, Launched 4 March 1994

The second mission of the United States Microgravity Payload on-board the STS-62 mission was supported with three accelerometer instruments: the Orbital Acceleration Research Experiment (OARE) and two units of the Space Acceleration Measurements System (SAMS). The March 4, 1994 launch was the fourth successful mission for OARE and the ninth successful mission for SAMS. The OARE instrument utilizes a sensor for very low frequency measurements below one Hertz. The accelerations in this frequency range are typically referred to as quasisteady accelerations. One of the SAMS units had two remote triaxial sensor heads mounted on the forward MPESS structure between two furnance experiments, MEPHISTO and AADSF. These triaxial heads had low-pass filter cut-off frequencies at 10 and 25 Hz. The other SAMS unit utilized three remote triaxial sensor heads. Two of the sensor heads were mounted on the aft MPESS structure between the two experiments IDGE and ZENO. These triaxial heads had low-pass filter cut-off frequencies at 10 and 25 Hz. The third sensor head was mounted on the thermostat housing inside the IDGE experiment container. This triaxial head had a low-pass filter cut-off frequency at 5 Hz. This report is prepared to furnish interested experiment investigators with a guide to evaluating the acceleration environment during STS-62 and as a means of identifying areas which require further study. To achieve this purpose, various pieces of information are included, such as an overview of the STS-62 mission, a description of the accelerometer system flown on STS-62, some specific analysis of the accelerometer data in relation to the various mission activities, and an overview of the low-gravity environment during the entire mission. An evaluation form is included at the end of the report to solicit users' comments about the usefulness of this series of reports

An Automatic Phase-Change Detection Technique for Colloidal Hard Sphere Suspensions

Colloidal suspensions of monodisperse spheres are used as physical models of thermodynamic phase transitions and as precursors to photonic band gap materials. However, current image analysis techniques are not able to distinguish between densely packed phases within conventional microscope images, which are mainly characterized by degrees of randomness or order with similar grayscale value properties. Current techniques for identifying the phase boundaries involve manually identifying the phase transitions, which is very tedious and time consuming. We have developed an intelligent machine vision technique that automatically identifies colloidal phase boundaries. The algorithm utilizes intelligent image processing techniques that accurately identify and track phase changes vertically or horizontally for a sequence of colloidal hard sphere suspension images. This technique is readily adaptable to any imaging application where regions of interest are distinguished from the background by differing patterns of motion over time

Distributed and recoverable digital control system

A real-time multi-tasking digital control system with rapid recovery capability is disclosed. The control system includes a plurality of computing units comprising a plurality of redundant processing units, with each of the processing units configured to generate one or more redundant control commands. One or more internal monitors are employed for detecting data errors in the control commands. One or more recovery triggers are provided for initiating rapid recovery of a processing unit if data errors are detected. The control system also includes a plurality of actuator control units each in operative communication with the computing units. The actuator control units are configured to initiate a rapid recovery if data errors are detected in one or more of the processing units. A plurality of smart actuators communicates with the actuator control units, and a plurality of redundant sensors communicates with the computing units

Detecting Phase Boundaries in Hard-Sphere Suspensions

A special image-data-processing technique has been developed for use in experiments that involve observation, via optical microscopes equipped with electronic cameras, of moving boundaries between the colloidal-solid and colloidal-liquid phases of colloidal suspensions of monodisperse hard spheres. During an experiment, it is necessary to adjust the position of a microscope to keep the phase boundary within view. A boundary typically moves at a speed of the order of microns per hour. Because an experiment can last days or even weeks, it is impractical to require human intervention to keep the phase boundary in view. The present image-data-processing technique yields results within a computation time short enough to enable generation of automated-microscope-positioning commands to track the moving phase boundar
