Moths Taken in Berrien County, Michigan (with 102 New County Records)

(excerpt) Moore (1955) published a listing of the moths of Michigan, exclusive of the Tineoidea, Other writers (anon., 1968; Voss, 1970) have extended the list of Michigan records. During the fall of 1970, and through the summer of 1971, I lived in Sawyer, Berrien County and collected a number of records new for that area. At the encouragement of M.C. Nielsen, a listing of these records is made available

Helping Our Students Reach Their Full Potential: The Insidious Consequences of Stereotype Threat

A psychological phenomenon may be a significant cause of academic underachievement by minorities in law school. This phenomenon, called stereotype threat, occurs as a result of the fear of confirming a negative group stereotype (such as African-Americans are not as intelligent as Whites). When subject to this threat — as a consequence of being confronted with environmental or explicit triggers — people do worse in academic settings than they otherwise are capable of doing. In this article, I explore the implications of the research on stereotype threat for law schools and make several recommendations to deal with the threat. There are natural implications for law school admissions, of course. If a portion of our applicant pool is affected by stereotype threat, then we cannot trust the accuracy of the metrics we typically use in law school admissions, i.e., prior academic performance and LSAT scores of law school applicants. Indeed, those credentials actually may under-evaluate the academic potential of these applicants, who are often minority students. This should cause law schools to reevaluate their admissions policies. After students are admitted, law school provides fertile ground within which stereotype threat can flourish. This, of course, means that the performance of minorities in law school — in class, on exams, and in other areas — is likely to be diminished, such that many minorities will not perform up to their academic capacity. And, obviously, we would expect this same dynamic to play out on the bar exam. Law schools can address stereotype threat at each of these levels, and they should do so. This article lays out a framework for understanding and dealing with the threat

Orifice plates in a shock tube

This note points out some interesting aspects of a recent study of the flow resulting from the use of area change near the diaphragm of a shock tube. (1) Earlier studies (2,3) have been directed toward the use of area change for increasing the available shock speed, and thus have considered geometries where A4/A1 > 1 and A*/A1 = 1 [see notation on Fig. 1(a)]. In the current work, shock tubes with arbitrary values of these parameters are considered over the complete range of Ms (the shock Mach number)

A Dwarf Form of \u3ci\u3eEuptoieta Claudia\u3c/i\u3e (Lepidoptera: Nymphalidae)

During a collecting vacation in August, 1970, I captured several specimens of Euptoieta claudia (Cramer). After spreading the catch, the interesting gradation shown in the accompanying photograph was noted. Figure 1 shows a wing span range from 1 318\u27\u27 \u27to 2
