Xerophthalmia has been found to be an important cause of blindness in the Philippines. An earlier study had investigated its prevalence and epidemiology on the island of Cebu. The research now presented consists of an evaluation of the relative effectiveness of three different intervention strategies to control vitamin A deficiency in Cebu. These interventions were 1) a public health and horticulture intervention, 2) the provision of 200,000 IU of vitamin A to children every 6 months (the "capsule intervention"), and 3) the fortification of monosodium glutamate with vitamin A. A total of 12 areas or barangays were included. Each intervention was monitored in four different barangays, two urban and two rural, for almost 2 years. Similar examinations were performed before and after the interventions. The monosodium glutamate fortification was the only intervention that resulted both in a significant reduction in clinical signs of xerophthalmia and in a significant rise in serum vitamin A levels. Fortification is now being planned in three Philippine provinces.
An investigation of xerophthalmia was undertaken in four ecological zones in Cebu in the Philippines. One thousand seven hundred fifteen children aged 1 to 16 years were examined in 12 barrios. Clinical, biochemical and anthropometric data were collected from the children. Dietary and socioeconomic information was obtained from the households. Multivariate statistical techniques were used to examine factors possibly associated with xerophthalmia. Of children 47% had deficient or low serum vitamin A levels and 4.5% had clinical signs of xerophthalmia. Approximately 2% had both low serum vitamin A levels and clinical eye signs and were then defined as having active xerophthalmia. Vitamin A deficiency was more prevalent in males than females. Xerophthalmia was most common in the 4 to 6 year old age group. Diarrhea, roundworm infestation and measles were not positively correlated with xerophthalmia but whooping cough and tuberculosis were. Low intakes of carotene and vitamin A were associated with xerophthalmia but protein and fat intakes were not. A higher incidence of xerophthalmia occurred in children of working than nonworking mothers. Data on home production and use of vegetables and fruits are presented. The results of this study are being used to introduce three alternate intervention strategies to control xerophthalmia.
Since 1976, the American Assembly of Collegiate Schools of Business (AACSB) has encouraged business schools to include ethics in their curricula. Because lan guage is the means for conveying values, including ethical values, business com munication faculty play an important role in deciding what should be taught, and how. But until very recently, most researchers failed to look specifically at actual practices and perceptions in the workplace. To address that need, we conducted a survey of 250 business leaders concerning their ethical preferences and compared our results with an earlier study of business faculty and students. The survey, adapted from one used in the Arthur Andersen Business Ethics Program, consists of 20 narratives which presented respondents with the need to judge the impor tance of certain issues and their approval or disapproval of the action or decision described. We found no significant differences in responses to the 14 items which addressed ethical issues in such areas as creating health and environmental risks, taking credit when credit is not due, focusing on disability issues, deceiving cus tomers with products and services, and using insider information to gain personal advantage. We did find significant differences in responses to six narratives focused on ignoring wrongdoing in the workplace, doing special favors for others to gain personal advantage, and covering up flaws in merchandise or operations. Our results, and the survey instrument itself, provide useful tools for the business com munication classroom.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
