Anti-Semitism on Campus
The authors present results of a study that investigates and compares Jewish and non-Jewish students’ perceptions of the anti-Semitic atmosphere at the University of Massachusetts at Amherst.
The Impact of a University Policy on the Sexual Harassment of Female Students
Research on the sexual harassment of college and university students has been accumulating for over a decade. Surveys exploring the reported incidence of sexual harassment of students have been conducted at nearly twenty institutions of higher learning. While the majority of college and university surveys are similar in that they have been conducted by mail, comparison of results is difficult because of variations in sampling strategies, operational definitions of sexual harassment, and populations sampled [10]. Despite the incomparability of survey results, Dzeich and Weiner maintain that "again and again 20-30 percent of women students report they have been sexually harassed by male faculty during their college years" [7, p. 15]. Although the literature lacks solid statistics describing the national prevalence of sexual harassment on college and university campuses, the results of individual institutional studies affirm that sexual harassment is a problem for significant proportions of female students. Several studies found between one-quarter and one-third of women students affected by sexually harassing behaviors. Benson and Thompson's 1978 Berkeley study found that 29.7 percent of female seniors had experienced at least
Determination of Optimal Ball-Burnishing Parameters for Plastic Injection Moulding Steel
The objective of this study is to determine the optimal plane ball-burnishing parameters for plastic injection moulding steel PDS5 on a machining centre by utilising the Taguchi’s orthogonal array method. The design and manufacture of a burnishing tool are described. Four burnishing parameters, namely the ball material, burnishing speed, burnishing force and feed, were selected as the experimental factors in Taguchi’s design of experiments to determine the optimal burnishing parameters which have the dominant influence on surface roughness. The optimal burnishing parameters were found after carrying out the experiments specified by Taguchi’s L18 orthogonal table, by the analysis of variation, and by a full factorial experiment. The optimal plane burnishing parameters for the plastic injection moulding steel PDS5 were a combination of a tungsten carbide ball, a burnishing speed of 200 mm/min, a burnishing force of 300 N and a feed of 40 μm. The surface roughness Ra of the specimen can be improved from about 1 μm to 0.07 μm by using the optimal burnishing parameters for plane burnishing.
