Therapeutic touch as energy exchange: replication and extension.

This study replicated and extended previous published research which suggests that therapeutic touch involves an energy exchange. The theorem that eye and facial contact between therapeutic touch practitioners and subjects should not be necessary to produce the effect of anxiety reduction was deduced from the Rogerian conceptual system and tested. This theorem was not supported. Numerous explanations for the failure of the hypotheses to be supported are posited, among them the impact of the research design, effects related to the investigator as practitioner, and medication. The influence of medication in particular is so pervasive in the sample that it would seem to be the most reasonable explanation.

Early biochemical alterations induced by 2-acetylaminofluorene in rat liver.

Livers from rats fed the carcinogen 2-acetylaminofluorene (AAF) were analyzed at weekly or semiweekly intervals to correlate appearance of enzymatic markers in total liver homogenates with histochemical events accompanying formation of hyperplastic liver nodules. gamma-Glutamyltranspeptidase (gamma-GT)-positive foci appeared by day 11 and visible nodules were present by days 28-35. Specific activity of homogenate gamma-GT increased in parallel to formation of hyperplastic foci and nodules, declined and then rose again to 20-fold that of controls by day 77. Specific activity of ornithine decarboxylase increased in advance of that of gamma-GT, to a level of 8-fold above control during the period of formation of hyperplastic foci. An early response was a 2-fold rise in the specific activity of nucleoside diphosphate phosphatase during the first week of carcinogen administration. The specific activity of 5'-nucleotidase, known to increase during liver regeneration, declined as the animals aged and was not increased by the dietary AAF. The enzymatic alterations induced by AAF could not be mimicked by cell proliferation, diet stress or the hepatotoxicity induced by feeding 1.87% 4-acetamidophenol.

Wage determination and discrimination among older workers.

In this study, the determinants of the wage rates of a large sample of individuals aged 58 to 63 are first analyzed. Second, an explanation for the large discrepancies existing between the average wage rates earned by whites and nonwhites and by men and women is attempted. Human capital and geographic variables were found to be important wage determinants. Education, vocational training, years of job tenure, health, region of residence and local cost of living were significant explanators, especially for whites. Differences in these variables, however, cannot completely explain the wage differentials that exist by race and sex. There is a large unexplained component (especially in the male-female comparison) offering evidence of race and sex discrimination among older workers. In the case of sex discrimination, much of the problem appears to be occupational segregation--the crowding of women into low paying industries and occupations.
