Kinetics of chromium(V) formation and reduction in fronds of the duckweed Spirodela polyrhiza--a low frequency EPR study.

The uptake of chromate by the duckweed Spirodela polyrhiza was investigated with atomic absorption spectroscopy and the reduction of Cr(VI) to Cr(V) was measured using low frequency EPR spectroscopy. The biphasic kinetics of the uptake was fitted to parameters of a proposed kinetic model. Another model was developed to simulate chromate reduction. The first step of chromate reduction was found to be much faster than the uptake of Cr(VI) from the free space. Most probably, this step occurs already in the cell wall or on the cell membrane surface. Further reduction of Cr(V) to Cr(III) was estimated to be slower. The disappearance of the Cr(V) signal, following transfer of the plants into a Cr-free solution, lasted several tens of hours; the kinetics was mono- or biexponential depending on the length of Cr loading. The rate constants for Cr reduction in living plants were determined for the first time.

Reliability, criterion-related validity and qualitative comments of the Fourth Edition of the Stanford-Binet Intelligence Scale with a young adult population with intellectual disability.

The test-retest reliability and concurrent, criterion-related validity of the Fourth Edition of the Stanford-Binet Intelligence Scale (SB-IV) were examined in a young adult population with intellectual disability. Forty adults with mild to moderate intellectual disability (mean age = 20.8 years; SD = 1.8 years) were administered the SB-IV and retested approximately 5 weeks later (mean = 33.4 days, SD = 1.2). The Vineland Adaptive Behavior Scale: Interview Edition (VABS) was completed by a reliable informant within one week of the SB-IV testing. The test-retest reliability coefficients for the four SB-IV area and composite scores were all significant (P < 0.00). Individual subtest correlations tended to be lower but consistent across the two administrations. Moderate correlations were observed between the VABS composite and SB-IV composite scores. The present results provide support for the temporal reliability of the SB-IV and its concurrent, criterion-related validity in an exceptional sample.

[Talking to an "unconscious" patient?].

In our every day practice in intensive care unit, we have the constant worry to join words to our care, is it towards conscious our unconscious patients. This paper is the issue of a work of listening and thinking over from the nursing team, to the testimony of a patient who was in our unit for three months. This person was in the coma for long weeks, and he tells us afterwards about how he experienced this trial.

The impact of a community based health education program on the incidence of diarrheal disease in southern Thailand.

This study has demonstrated that additional training of service providers [village health volunteers (VHVs), village health communicators (VHCs)] in combination with the mobilization of village leaders and influentials to promote selective preventive health behavior, can have a marked impact upon the effective practice of these behaviors and diarrheal incidence. Further, this impact can be achieved through the existing staff structure, ie, VHV/VHCs of the national health program. For example, increased contact between these service providers and mothers of children under 5 years through home visits and attendance at meetings held by the service providers, contributed positively to the practice of selected preventive behaviors. If the national program provided similar training inputs on the promotion of selected preventive behaviors and increased service provider contacts, the program's impact upon diarrheal disease would be enhanced.

Socioeconomic and health programme effects upon the behavioral management of diarrhoeal disease in northeast Thailand.

This study investigates the effects of socioeconomic and health programme factors on preventive and curative health behaviors and assesses the impact of preventive health behaviors on the incidence of diarrhoea among children under five years of age. Methodological approaches included focus groups to uncover local definitions of diarrhoeal disease, a baseline survey which collected data on maternal preventive health behaviors for 1,364 children, and a monitoring system which collected data on the incidence of diarrhoea and on maternal curative behaviors among the same group of children. Results indicate that socioeconomic status and exposure to health programmes showed significant relationships with selected maternal preventive behaviors. Children whose mothers washed their hands before breastfeeding, gave their child food immediately after cooking and warmed foods each time before meals had significantly lower proportions with diarrhoea than children of mothers who did not practice these behaviors, and 70 percent of the children with diarrhoea were exposed to high risk of severe dehydration and related health complications. Implications of these findings for health programmes are discussed.

The relative impacts of vertical and integrated FP/MCH programs in rural Nepal.

The objectives of this analysis were to assess the probable impacts of vertical and integrated FP/MCH programs on family planning (knowledge, use, and intentions to use), family size preferences, fertility, and mortality (child and infant). The following discussion summarizes and draws conclusions regarding the results of this investigation. The vertical program showed a greater impact on knowledge of family planning than the integrated program. Increases in knowledge between 1975 and 1978 while controlling for social and demographic variables were greater in the vertical than the integrated areas. Multiple classification analysis at both household and village levels showed that the vertical program was a better predictor of knowledge and changes in knowledge than the integrated program. In addition, the vertical program showed consistently higher proportions of women with awareness of family planning among those segments of the population that could have the greatest impact on fertility reduction in the future--namely, the younger women who are either childless or just beginning their childbearing and those with husbands who have little or no education. Neither the vertical nor the integrated FP/MCH program showed an impact on current use or ever use of family planning. The very low levels and changes in levels of these factors between the programs showed almost no difference throughout the selected demographic and socioeconomic groups. In both program areas the proportions of ever use and current use increased substantially with the number of living sons, exceeding 14 percent and 10 percent, respectively, among women with three or more sons. There were virtually no family planning users or ever users among women with no sons. This appears to indicate that "son preference" (documented in the Nepal Fertility Survey) is an important factor affecting the incidence of family planning practice and may be a formidable obstacle to a substantial reduction in fertility. Family limitation generally may not be taken seriously until a couple has produced the desired number of sons. Hence, until the value of sons (perhaps as sources of labor, financial support and security in old age, and as performers of funeral rites for fathers) can be altered it is unlikely that a reduction in fertility beyond certain levels could occur. The vertical program showed a slightly greater impact on future intentions to use family planning than the integrated program.(ABSTRACT TRUNCATED AT 400 WORDS)

Differentials in fertility, family planning practice, and family size values in South Korea, 1965-1971.

Data from five Korean national KAP surveys of currently married women, conducted between 1965 and 1971, are analyzed to determine whether differentials have emerged or are emerging between urban and rural women in three factors of crucial importance for population growth: fertility, family planning practice, and family size values. Graphics are used throughout to analyze urban-rural differentials and trends in these factors over time. In addition, two statistical tests, the sign and binomial, are applied to the differentials to provide a tabular summary of results. Part I provides background information on population growth, urbanization, the achievements of the national family planning program, and economic development in Korea since the 1950's. Part II describes both urban-rural differentials in fertility, as measured by mean parity, for married women aged 30-39 between 1966 and 1971; and urban-rural differentials in the proportions of women aged 25-39 currently practicing family planning between 1965 and 1971. Part III analyzes urban-rural differences in ideal family size and ideal number of sons, controlling for number of living children and number of living sons. Part IV attempts to evaluate the impact of the national family planning program on the fertility, family planning practice, and family size values of the rural population by examining the findings on urban-rural differentials in the context of social and economic development, viewing the program as one of a multitude of variables that can affect these factors.
