[Review of] Calvin Winslow, ed. Waterfront Workers: New Perspectives on Race and Class

Students of race and ethnic relations have used two perspectives to explain the effects of industrialization on dominant and subordinate relations. One view holds that the process of industrialization results in individuals becoming detached from associations based in race and ethnicity as their life chances are determined by their participation and position in the economic order. A second perspective suggests that industrialization inevitably leads to tension and hostility between groups because they are forced to compete for scarce resources. The articles in Waterfront Workers: New Perspectives on Race and Class attempt to bridge the gap between these conflicting perspectives by suggesting that both may apply, as longshoremen who are racially and ethnically different attempt to adjust to social changes in their occupational setting

Computer program for the prediction of reorientation flow dynamics

Program uses Navier-Stokes and continuity equations for incompressible, viscous fluid as the basic equations governing reorientation flow dynamics. Program can simulate curved as well as straight-walled boundaries; has ability to calculate both free-surface and confined flows; and can be used in either cylindrical or plane geometry

Character and Candor Requirements for FCC Licensees

The Communications Act explicitly makes the applicant\u27s character an element in licensing. Applications must set forth such facts as the Commission by regulation may prescribe as to the citizenship, character, and financial, technical, and other qualifications of the applicant to operate the station. Even in the absence of such guidance, the Commission could scarcely ignore evidence of bad character in making its ultimate determination whether a grant will serve the public convenience, interest, or necessity. The Act mentions the related problem of misrepresentation only in connection with the Commission\u27s power to revoke licenses. Misrepresentation, or lack of candor, may, nevertheless, be treated as a defect of character, or as an independent ground for finding that public interest does not call for licensing someone who deceives the licensing authority. There is, it will appear, not much question about the Commission\u27s power to demand high standards of truthfulness and candor as well as of character. There is also little doubt that, at least for the last decade, the Commission has set high standards. The questions that merit attention are rather these: 1) In what circumstances is the power exercised? 2) Is it abused, either by the Commission or by parties who bring before the Commission unwarranted charges of bad character or of deception? 3) If there are abuses, how can they be checked? It may be said at the outset, without trying to prefigure any recommendations in conclusion, that there appear to be two forms of excessive concern with character and candor. The first is a tendency of parties, in hard-fought comparative proceedings, to dredge up remote and far-fetched charges of any conceivable kind of wrongdoing. The second, in which the Commission has taken the lead, is to make questionable inquiries about radical or subversive political associations. Examples of these practices will emerge from the discussion that follows

Measurement of extremely low fluid permeabilities of rocks significant to studies of the origin of life Final report

Permeater for measuring low fluid permeabilities of rocks used to study origin of lif

Calorimetric detection of neutral-atom content of ion beam

Energy deposition technique deduces neutral-beam flux or dose from measured values of incremental resistance increases in platinum wire passed through beam. Steady-state heat balance analysis led to equivalent neutral-beam current. Method was used to detect neutral-atom content of 60-keV argon ion beam

Random pulse generator

An exemplary embodiment of the present invention provides a source of random width and random spaced rectangular voltage pulses whose mean or average frequency of operation is controllable within prescribed limits of about 10 hertz to 1 megahertz. A pair of thin-film metal resistors are used to provide a differential white noise voltage pulse source. Pulse shaping and amplification circuitry provide relatively short duration pulses of constant amplitude which are applied to anti-bounce logic circuitry to prevent ringing effects. The pulse outputs from the anti-bounce circuits are then used to control two one-shot multivibrators whose output comprises the random length and random spaced rectangular pulses. Means are provided for monitoring, calibrating and evaluating the relative randomness of the generator

Early Conclusions from The Mixed-Income Demonstration Program: Reaching Extremely Low-Income Families in Mixed-Income Settings

This report contains the results of a special Congressionally-appropriated grant program to develop affordable multi-family housing that serves extremely low income households. The grants included capital grant "gap" funding for NeighborWorks organizations operating and preserving affordable multi-family housing

New species, records, and a synonymy of African Sisyridae (Neuroptera)

Two species of the genus Sisyra Burmeister (Neuroptera: Sisyridae), S. cameroonensis, n. sp., and S. gruwelli, n. sp., are described from the African Republic of Cameroon. Sisyra pallida Meinander is synonymized with Sisyra delicata Smithers, new synonymy, after comparison of the types of the former with topotypic paratypes of the latter. Type material of Sisyra nilotica Tjeder appears to be lost. Examples of Sisyra are recorded from Nigeria, Ethiopia and Uganda. A second species of the endemic African genus, Sisyborina, Monserrat, S. scitula, n. sp., is described from Cameroon, Guinea, and Zambia
