Direct and Intermediated Marketing of Local Foods in the United States
This study uses nationally representative data on the marketing of local foods to assess the relative scale of local food marketing channels. This research documents that sales through intermediated marketing channels, such as farmersâ sales to local grocers and restaurants, account for a large portion of all local food sales. Small and medium-sized farms dominate local foods sales marketed exclusively through direct-to-consumer channels (foods sold at roadside stands or farmersâ markets, for example) while large farms dominate local food sales marketed exclusively through intermediated channels. Farmers marketing food locally are most prominent in the Northeast and the West Coast regions and areas close to densely populated urban markets. Climate and topography favoring the production of fruits and vegetables, proximity to and neighboring farm participation in farmersâ markets, and good transportation and information access are found to be associated with higher levels of direct-to-consumer sales.Local foods, direct marketing channels, direct sales, intermediated sales Acknowledgments: The, Agricultural and Food Policy, Marketing,
Homogeneous and heterogeneous multiple representations in equationâsolving problems: An eyeâtracking study
Multiple external representations (MERs) play an important role in the learning field of mathematics. Whereas the cognitive theory of multimedia learning and the integrative text and picture comprehension model assume that the heterogeneous combination of symbolic and analogous representations fosters learning; the design, functions, and tasks framework holds that learning benefits depend on the specific functions of MERs. The current paper describes a conceptual replication study of one of the few studies comparing single representations, heterogeneous, and homogeneous MERs in the context of mathematics learning. In a balanced incomplete block design, the participants were provided single representations (a graphic, text, or formula) or a heterogeneous (e.g., textâ+âgraphic) or homogeneous (textâ+âformula) combination of these to solve linear system of equations problems. In accordance with previous research, performance was superior in conditions providing MERs compared to singleârepresentation conditions. Moreover, heterogeneous MERs led to time savings over homogeneous MERs which triggered an increase in cognitive load. Contrary to previous research, text was the least fixated representation whereas the graphical representation proved to be most beneficial. With regard to practical implications, experts should be fostered through more challenging homogeneous MERs whereas novices should be supported through the accessible graphic contained in heterogeneous MERs
