Antibodies to Toxoplasma were measured by enzyme linked immunosorbent assay (ELISA) in sera from 159 abattoir workers, 142 pig farmers, and 106 grain or berry farmers. Farmers occupationally exposed to pigs had antibodies in 53 (37%) cases, abattoir workers in 40 (25%) cases, and farmers not exposed to pigs in 24 (23%) cases. In each group antibodies were more prevalent among those who had a ca...

The perceptions of farmers about risks in production of fruits and vegetables have been analysed using structured survey method. The study is based on the survey of a total of 634 farmers, comprising 188 fruit farmers and 446 vegetable farmers, covering six districts of Uttar Pradesh, namely, Lucknow, Allahabad, Gorakhpur, Moradabad, Jhansi and Agra. The perceived priorities of farmers about ma...

OBJECTIVE Determine the feasibility and outcome of a pilot program to increase farm workers' use of hearing protection when performing activities with high noise exposure. DESIGN The study was a quasi-experimental study. SAMPLE Eight intervention farmers and 17 comparison farmers participated in the study. MEASURES Before and after the intervention, farmers completed a survey to identify ...

If architecture representation is the problem (P), and the UML is the solution (S), how do we get from P to S? In this paper, I introduce the idea of viewpoint modeling as a part of the answer. A viewpoint, as defined in IEEE 1471, defines a set of architectural concerns and the resources needed to address those concerns. A viewpoint gives an architect the resources with which to construct an a...

Studies on personal dust and endotoxin concentrations among animal farmers have been either small or limited to a few sectors in their investigations. The present study aimed to provide comparable information on the levels and variability of exposure to personal dust and endotoxin in different types of animal farmers. 507 personal inhalable dust samples were collected from 327 farmers employed ...

OBJECTIVES Agricultural workers are known to have occupational skin diseases. The prevalence and pattern of skin diseases are unknown in Taiwanese fruit farmers. The objective of this study is to determine the work exposure, prevalence of skin diseases, and sensitivity to common skin allergens and agricultural chemicals in fruit farmers of southern Taiwan. METHODS 122 fruit farmers who regula...

In the Savannah region of West Africa, the highly variable rainfall and poor soils have been shown to di€erentially a€ect the yield potential of various crops. The paper applies a simple risk programming model to assess the e€ects of price and yield risk on the incomes of smallholder farmers in northern region of Coà te d'Ivoire. The analysis showed that by considering price and yield risks, it...

Farmers' objectives and the factors a€ecting them were studied in 91 dairy farms in Costa Rica. Objective's hierarchies were studied using Rokeach's technique with a mixture of personal, economic and familiar goals. A canonical correlation analysis was performed to ®nd out simple and canonical correlations between farmers'/farms' characteristics and objective priorities. Factor analysis combine...

Farmers' perceptions of birds' interactions with agricultural production systems are fundamental to species conservation efforts. In the present study, we evaluated the perceptions of birds held by farmers who engage in conventional and non-conventional agricultural production processes and the implications of potential differences in these perceptions on species conservation. To accomplish thi...
