MULTIPLE JOB-HOLDING AMONG U.S. FARM WOMEN: OFF-FARM WORK AND ON-FARM DECISION-MAKING USING A BARGAINING APPROACH

Participation rates for farm women in off-farm labor markets continue to increase, as does their participation in making major farm decisions such as whether to buy or sell land, adopt a new production practice or invest in farm equipment. Data from the Survey of U.S. Farm Women conducted in 2001 by Penn State in collaboration with researchers at the Economic Research Service and in collaboration with NASS are used to examine the multiple work roles of farm women off the farm and in farming. Descriptive statistics for the results of the 2001 survey are compared to those from the last major survey of U.S. farm women conducted by Rosenfeld in 1980. Then, using data limited to farm couples, models of job choice considering jointness in participation are estimated and tested under conditions of presence or absence of children, followed by estimation of models of on-farm decision-making using a household bargaining approach. Of particular interest is the effect of the >path= of intergenerational farm transfer (i.e., if inherited or purchased through her family or through her spouse=s/partner=s family) on job choice and farm decision-making. Results show that the work decisions of farm couples are correlated, both when children are present and when they are not. Further, the >path= of farm transfer influences the choices that women make. The transferof the farm through her family has in some cases a positive influence on her choices, both in terms of her involvement on the farm and her participation in farm decisions. Farm transfer through the husband=s/partner=s family generally has strong negative influences on her participation in farm decision-making.

IMPACT OF CREDIT ON LABOR ALLOCATION AND CONSUMPTION PATTERNS IN MALAWI

Using a bargaining framework, this paper analyzes the impact of access to credit on household labor allocation and on consumption expenditures in rural Malawi. The labor participation decisions of married men and women and female heads are estimated using random-effects probit models, and are corrected for endogeneity of access to credit. Expenditure shares are estimated using ordinary least squares and Tobit models.Food Consumption/Nutrition/Food Safety, Labor and Human Capital,

Galactic R Coronae Borealis Stars: The C-2 Swan Bands, The Carbon Problem, And The C-12/C-13 Ratio

Observed spectra of R Coronae Borealis (RCB) and hydrogen-deficient carbon (HdC) stars are analyzed by synthesizing the C-2 Swan bands (1, 0), (0, 0), and (0, 1) using our detailed line list and the Uppsala model atmospheres. The (0, 1) and (0, 0) C-2 bands are used to derive the C-12 abundance, and the (1, 0) (CC)-C-12-C-13 band to determine the C-12/C-13 ratios. The carbon abundance derived from the C-2 Swan bands is about the same for the adopted models constructed with different carbon abundances over the range 8.5 (C/He = 0.1%) to 10.5 (C/He = 10%). Carbon abundances derived from C I lines are about a factor of four lower than the carbon abundance of the adopted model atmosphere over the same C/He interval, as reported by Asplund et al., who dubbed the mismatch between adopted and derived C abundance as the "carbon problem." In principle, the carbon abundances obtained from C-2 Swan bands and that assumed for the model atmosphere can be equated for a particular choice of C/He that varies from star to star. Then, the carbon problem for C-2 bands is eliminated. However, such C/He ratios are in general less than those of the extreme helium stars, the seemingly natural relatives to the RCB and HdC stars. A more likely solution to the C-2 carbon problem may lie in a modification of the model atmosphere's temperature structure. The derived carbon abundances and the C-12/C-13 ratios are discussed in light of the double degenerate and the final flash scenarios.Robert A.

STRESS AMONG FARM WOMEN:AN ANALYSIS OF FARM HOUSEHOLDS IN PENNSYLVANIA

Farming is among the high-stress occupations in the United States and farm women have higher stress scores due to multiple job holdings. The study investigates the determinants of time stress experienced by farm women in Pennsylvania applying an economic model of stress developed by Hamermesh and Lee (2003).Farm Management,

Agricultural Household-Firm Units: Adjustments to Change

This paper assesses agricultural household-firm unit models to determine a useful typology for agricultural policy assessment that draws upon their use. Both standard and bargaining models for analyzing household decisions, including production, consumption, labor, credit, fertility and child schooling, intergenerational transfer, among other key behaviors of households are discussed, as well as data and estimation issues often encountered with household models. Relevant dimensions of a country or region typology are then suggested, focusing on (1) the extent to which markets, particularly labor markets, are perfect, missing or mixed; (2) relevant intra-household and key demographic considerations; and (3) the differentiation of particular household-firm units that are particularly disadvantaged and may be of the most critical policy concern.agricultural households, farm households, labor, labor adjustments, off-farm employment, Consumer/Household Economics, Labor and Human Capital,

One step procedure for screening and diagnosis of gestational diabetes mellitus by diabetes in pregnancy study group of India

Background: In the Indian context, screening for Diabetes is essential in all pregnant women, as the Indian women have an eleven-fold increased risk of developing glucose intolerance during pregnancy. For this, we need a simple procedure which is economical and feasible. Hence this study was undertaken as a screening as it is acceptable, economical and feasible to perform. Aim of this study was to assess the feasibility of one step procedure for screening and diagnosis of Gestational Diabetes Mellitus by Diabetes in Pregnancy Study Group of India (DIPSI).aim of the study was to study the occurrence of Gestational Diabetes mellitus, Tumkur, to assess the sensitivity and specificity of glucose challenge test, to assess the need for universal screening and to study the maternal and perinatal outcomes in patient with Gestational Diabetes Mellitus.Method: Type of study was prospective study. this study included 200 pregnant women attending the antenatal OPD in Sri Siddhartha Medical College, Tumkur. Data collection was in a predesigned proforma. Pregnant women with 24-28 weeks of gestation were given 75 grams of oral glucose load, irrespective of their meal and venous blood sample drawn after 2 hours. If blood glucose value was ≥140mg/dl, the screening was considered as DIPSI positive. These patients underwent OGTT.Results: Incidence of GDM was found to be 3.5% in the patients studied. 40% of cases did not have risk factors, hencethere is a need for universal screening. DIPSI was positive in 10 cases, of which 7 were OGTT positive. Patients were managed with diet and insulin. The maternal and perinatal outcome of pregnancy was good.Conclusion: For universal screening, DIPSI performed irrespective of last meal timing with 75g glucose load is a patient friendly approach. This method recommended by WHO serves both as a one-step screening and diagnostic procedure & is easy to perform besides being economical

Mutual Coupling in Phased Arrays: A Review

The mutual coupling between antenna elements affects the antenna parameters like terminal impedances, reflection coefficients and hence the antenna array performance in terms of radiation characteristics, output signal-to-interference noise ratio (SINR), and radar cross section (RCS). This coupling effect is also known to directly or indirectly influence the steady state and transient response, the resolution capability, interference rejection, and direction-of-arrival (DOA) estimation competence of the array. Researchers have proposed several techniques and designs for optimal performance of phased array in a given signal environment, counteracting the coupling effect. This paper presents a comprehensive review of the methods that model and mitigate the mutual coupling effect for different types of arrays. The parameters that get affected due to the presence of coupling thereby degrading the array performance are discussed. The techniques for optimization of the antenna characteristics in the presence of coupling are also included
