Although agricultural biotechnology has been a seminal reference point in risk perception studies, public awareness of their exposure to risk deriving from this new technology has been minimal at best. However, recent events indicate there may be growing public concern as new variations of this technology appear. Understanding what drives perceptions of benefits from the third generation of the agricultural biotechnology and what determines public worries are keys for the future of this technology. To this end, this study analyzes survey data from the midsouth region of the United States to construct four separate regression models of perceived benefits from and worries over plant‐made industrial products and plant‐made pharmaceuticals. Findings suggest that while prior experience with and knowledge about agricultural biotechnology has an impact on perceptions of benefits and worries, trust in farmers plays a highly important role in determining perceptions. 相似文献

This article analyzes demographic change in Bremen 1815–1914 against the background of changing employment opportunities. Within the pre-industrial employment structure, which still prevailed in the decades after 1850, in-migrants were particularly disadvantaged. When modern industries developed, the situation changed. At the beginning of the twentieth century both male and female in-migrants benefited from a higher life expectancy than the city-born population had. The strong sectoral changes in employment opportunities in Bremen at the turn of the century reinforced the trends towards family limitation. More skilled in-migrants felt the need to adapt their reproductive behavior to facilitate upward social mobility. The article argues for a wider use of archival data, like those used in their study, to explore issues relating to urban demographic change in German cities during industrialization. 相似文献
