Food Safety Resources on the World Wide Web

ABSTRACT

Issues of food safety are as important today than during any time in history. There is a lot of information available on the World Wide Web pertaining to food safety. Finding and sorting through all of the information for reliable and credible resources can take a lot of time and effort. Furthermore, are those sources updated as information changes? This is a critical question, as outbreaks and opinions can change moment to moment. The Food Safety Webliography provides a wide range of credible resources available to the general public and covers an expansive breadth of food-safety related topics.

课桌椅产业发展现状及标准修订探讨

符合学生身体状况的课桌椅产品对保持健康的学习环境有着重要的作用。随着各种新材料的引入,也带来各种安全问题,如塑料中的邻苯二甲酸酯、多环芳烃、多溴联苯、重金属等,油漆涂料中的重金属、苯系化合物、TVOC等,人造板中的甲醛、TVOC等,以及其他新材料的有害物质,这些问题急需有一个全面的标准体系去应对。标准修订以后将促进产品技术升级,加快优胜劣汰的过程,提升其产品的质量等级,淘汰落后的小型作坊,保障孩子们的健康安全,因此修订新的标准意义重大而深远。     

通识教材《世界农业文明史》编撰的缘起、内容和展望

Recent advances in relationship between diversity of gut microbiota and health

Trillions of microbes inhabit the human intestine, forming a complex microecological community. It has been found that the gut microbiotas contribute nutrients and energy to the host, and they are also involved in the occurrence and development of human diseases. With the continuous development of related research, there is increasing evidence suggesting a close relationship between gut microbiota and human diseases. The discovery of this relationship affects the development of modern health care individually. In this review, we focus on the influence factors to the diversity of gut microbiota, which has influences on colorectal cancer, aging, obesity, immunity, drug effects and malnutrition.     

Motivations for adopting biological control among Iranian rice farmers

While research on biological control of crop pests is quite popular, it seldom targets motivations of farmers for adopting this practice. A survey of 283 rice farmers was conducted in Mazandaran province of northern Iran to study farmers' motivations for biological control adoption as an alternative control method of Asiatic rice borer [Chilo suppressalis (Walker)] and explain potential differences in motivations among different groups of farmers. Face to face interviews were used to address farmers' motivations based on a list of motivation statements found in previous studies and modified by extension officers and farmers who had adopted biological control in the study area. Factor analysis of a motivation list with 15 items revealed four main groups of factors explaining the adoption of biological control by rice farmers; these were ‘health maintenance’, ‘economic benefit’, ‘social acceptance’, and ‘environmental protection’. Men gave high scores to motivations related to ‘economic benefit’ and ‘social acceptance’, whereas women preferred mostly motivations related to ‘health maintenance’. Well-educated farmers (e.g., some college education) preferred motivations for ‘health maintenance’ more than farmers with lower education or no education at all. Participation in extension programs was associated with preference of non-economic motivations of biological control adoption, while membership in local associations (such as rural cooperatives or producers' groups) encouraged motivations related to ‘social acceptance’. Farmers who used family labor force in their fields or farmers who perceived pesticides as harmful substances showed strong motivations primarily for ‘health maintenance’ along with ‘environmental protection’. Small area of land under cultivation and low annual farm income were strongly linked with motivations for ‘economic benefit’. Besides economic motivations, policies for the promotion of biological control adoption should embrace a wide set of farmers' motivations when developing new and properly tailored extension programs.
