Teaching the Basic Ethics Class Through Simulation: The Northwestern Program in Advocacy and Professionalism

The Northwestern University School of Law created and published a set of materials for teaching the basic ethics course principally through the simulation method. Burns provides a very compressed summary of the underlying program, describes the classes themselves and the mix of teaching methods professors employ, and briefly discusses the program materials

Mixing fuel particles for space combustion research using acoustics

Part of the microgravity science to be conducted aboard the Shuttle (STS) involves combustion using solids, particles, and liquid droplets. The central experimental facts needed for characterization of premixed quiescent particle cloud flames cannot be adequately established by normal gravity studies alone. The experimental results to date of acoustically mixing a prototypical particulate, lycopodium, in a 5 cm diameter by 75 cm long flame tube aboard a Learjet aircraft flying a 20 sec low gravity trajectory are described. Photographic and light detector instrumentation combine to measure and characterize particle cloud uniformity

Global Apparel Production and Sweatshop Labor: Can Raising Retail Prices Finance Living Wages?

This paper provides some empirical evidence on issues raised by the global antisweatshop movement. We first consider the relationship between wage and employment growth, finding no consistent trade-off between them. We then measure the share of labor costs in the production of garments in the United States and Mexico. We find that the retail price increases necessary to absorb the costs of substantially raising wages are small, well within the range of price increases that polls suggest U.S. consumers are willing to pay. We close by considering some implications of these results.Global sweatshop labor; empirical analysis

Reactions of The Thiosemicarbazones

The investigation described in the following pages forms one portion of an extensive research programme being carried out in the Department of Organic Chemistry of The Royal Technical College. The work is under the general supervision of Professor Forsyth J. Wilson and includes the reactions of the semicarbazones and semioxamazones as well as those of the thiosemicarbazones. Neuberg and Neimann (Ber. 1902, 35, 2049) have shown that the thiosemicarbazones C:N.NH.CS.NH2, possess the property of forming metallic derivatives, one of the hydrogen atoms being replaced by an equivalent of silver, copper, or mercury. The present investigation was undertaken to determine if, by the action of halogenated compounds, the hydrogen atom replaceable by metal could be replaced by alkyl or other substituents. The known metallic derivatives were found to be unsuitable for this work and the sodium derivative of acetone thiosemicarbazone was the starting material chiefly employed. The reactions of the sodium derivative with ethyl bromide, propyl bromide, n-butyl bromide, benzyl chloride and allyl iodide were investigated, with the result that a new series of S-alkylated thiosemicarbazones has been obtained. The products of hydrolysis of these S-alkylated compounds have also been examined. An attempt was made to prepare an optically active thiosemicarbazone by the action of 1-menthyl chloroacetate on the sodium derivative but the product obtained proved to be a thiohydantoin derivative of a new type; a ring closure having been effected. This rather interesting result led to the investigation of the action of the sodium derivative on the esters of halogenated acids. In the case of the esters of chloroacetic acid, ethyl α-bromopropionate, ethyl α-bromo-n-butyrate, and ethyl bromophenylacetate the products of the reaction were found to be derivatives of 2. 4 diketotetra-hydrothiazoles of the type The products of hydrolysis of these cyclic compounds were also examined. The esters of β-halogenated acids do not yield a six membered ring but were found to lose hydrogen halide with formation of the esters of the corresponding unsaturated acid. The cases investigated were those of ethyl β-bromo-n-butyrate and ethyl β-bromo-β-phenylpropionate with acetone sodio thiosemicarbazone. The action of the esters of y-halogenated acids was found to proceed as in the ease of those of the β-halogenated acids; ethyl y-chloro-n-butyrate, ethyl y-chlorvalerate, and ethyl y-chloroisocaproate yielding esters of unsaturated acids by loss of hydrogen halide. The reaction between ethyl ω-bromo-o-toluate, CH2Br which may be regarded as a y-halogenated acid ester, and acetone sodio thiosemicarbazone was found to proceed exactly as in the case of the alkyl halides; the structure of the product, as deduced from a study of the products of hydrolysis, being analogous. Another attempt to obtain an optically active thiosemicarbazone by the action of 1-dimethylchlorosuccinate on the sodium derivative gave a solid of low melting point which did not contain sulphur or nitrogen and was not, therefore, further investigated. Ethyl chlorocarbonate and phenyl chlorocarbonate have been found to react with the sodium derivative of acetone thiosemicarbazone in benzene suspension, with formation chiefly of the 1-carbethoxy or 1-carbophenoxy thiosemicarbazide R.OOC.NH.NH.CS NH2. Carbon dioxide is also formed, together with varying amounts of diethyl carbonate or diphenyl carbonate and the carboethoxy or carbophenoxy derivative of the thiosemicarbazone. The action of iodine on the sodium derivative of acetone thiosemicarbazone was tried but was found to give negative results; ethylene dibromide also failed to react. Preliminary work on the action of the amines on the thiosemicarbazones showed that aniline reacts with acetone thiosemicarbazone at 160 C. with vigorous evolution of ammonia and formation of a resinous product which could not be purified. Benzylamine reacts with acetone thiosemicarbazone at 140-145C , ammonia is evolved and a mixture of products formed, while with acetophenone thiosemicarbazone benzylamine reacts at a temperature of 130-135 C. with formation chiefly of the corresponding 4-benzyl thiosemiearbazone C:N.NH.CS. NHCH2.C6H5; a yield of 60% of the theoretical being obtained

THE FIRST HALF-CENTURY OF THE COLLEGE OF THE PACIFIC

It is significant that the history of California’s oldest incorporated college has never been written in detail. A pamphlet and several lengthy newspaper and magazine articles have, to this time, sufficed. It therefore became my duty in writing this thesis to amass a quantity of material from the original sources. The thesis represents the first half of a piece of work which ultimately, it is hoped, will portray a century of development by the College. It is expected that the complete work will be released shortly before the Centennial Celebration
