Analysis and classification of common vegetable oils

The analysis of fatty acids from common vegetable oils was investigated for application to forensic casework. A base-catalyzed transesterification of the fatty acids to fatty acid methyl esters using tetramethylammonium hydroxide was simple, rapid, straightforward and inexpensive. Canola, corn, olive, peanut, safflower, soybean and sunflower oils were able to be classified based on their fatty acid methyl ester profiles. Using gas chromatography-mass spectrometry, the detection limits for canola, corn, olive, peanut and safflower oils were determined to be 0.4 mg/mL or less and 0.2 mg/mL or less for soybean and sunflower oils.     

Transfers of Technology: A Basic Primer On Tax Considerations

The objective of this paper is to introduce managers of R&D operations to tax issues that must be considered when technology is transferred across international boundaries within the same company. The tax implications are often misunderstood or even overlooked in the technology transfer process. The paper explains how countries seek to tax their fair share of the income earned inside their borders. Since the amount of income earned depends on the price for technology paid by one part of a company to another, this transfer price is of keen interest to the tax authorities. To preserve their tax bases, therefore, countries establish rules to regulate the international transfer of goods and services, including technology, between related parties. This paper provides an overview of the economic principles underlying these rules, and illustrates their application with a series of examples.     

Self-image complexity and identity formation in adolescence: Longitudinal studies

Using a specially designed Q-sort technique, multiple self-images which were held by each of 60 adolescents were studied. Sixty normal and psychiatrically hospitalized adolescents were tested initially and then every 6 months for 12–18 months. Each subject's self-images were analyzed in terms of their complexity. Results showed that, as predicted, the patients and normals differed significantly. The patients had consistently lower complexity scores on each trial. The patients' and normals' patterns of complexity scores are discussed in terms of their reflecting the ego identity configurations described clinically by Erikson and operationally defined herein.This study was supported in part by a Research Scientist Development Award (Kl-70-178) from the National Institute of Mental Health.Received his medical training at Yale University School of Medicine and his psychiatric training at Massachusetts Mental Health Center. Currently continuing graduate training in personality and development in the Psychology and Social Relations Department at Harvard University. Present research interests are in the interplay between fantasy and nonverbal process in interracial adolescent dyads; and in the longitudinal study of adolescent identity development.
