Temporal Aggregation And Treatment Of Zero Dependent Variables In The Estimation Of Food Demand Using Cross-Sectional Data, Kristyn Leffler
Temporal Aggregation And Treatment Of Zero Dependent Variables In The Estimation Of Food Demand Using Cross-Sectional Data, Kristyn Leffler
All Theses
This study analyzes U.S. consumers' demand for eight food commodity groups: Cereal and Bakery goods, Meat and Eggs, Dairy, Fruits and Vegetables, Nonalcoholic Beverages, Fats and Oils, Sugar and Sweets, and Miscellaneous goods. The estimation of the demand system of equations is carried out using the EASI demand model of Lewbel and Pendakur (2009) and five years of data (2002-2006) from the Nielsen Homescan program. Two different levels of temporal aggregation, monthly and the average month within a year, referred to as 'annual' were considered. Using the monthly data, I evaluated the performance of two econometric methods to account for …
Serving As Suppliers To Institutional Foodservices: Supply Chain Considerations Of Small And Medium Scale Specialty Crop Producers, Laura Westray
Serving As Suppliers To Institutional Foodservices: Supply Chain Considerations Of Small And Medium Scale Specialty Crop Producers, Laura Westray
All Theses
Institutional foodservice, which includes schools, hospitals, and long-term care facilities, is an important food marketing channel. The centralized nature of the US food system effectively, and supply, logistic and other constraints, effectively precludes small and medium scale (SMS) specialty crop producers from serving as suppliers to these types of operations. Passage of The Food Safety Modernization Act (FSMA) and increasing public attention to food safety issues, further complicates this matter. While the FSMA Tester-Hagen Amendment provides regulatory exemptions for SME producers, it is likely that in the future food purchases on or behalf of institutions will require more stringent food …
Effects Of Cytokinin On Multiplication And Rooting Of Aloe Barbadensis During Micropropagation On Agar And Liquid Medium, Jeffrey Adelberg, Jacqueline Naylor-Adelberg
Effects Of Cytokinin On Multiplication And Rooting Of Aloe Barbadensis During Micropropagation On Agar And Liquid Medium, Jeffrey Adelberg, Jacqueline Naylor-Adelberg
Publications
Aloe barbadensis (syn. Aloe vera) was micropropagated on agar and liquid medium at varied benzyladenine (BA) and meta-topolin (MT) concentrations
(0, 1, 3.2, and 10 μM) for three successive culture cycles and then transferred to a greenhouse for growth. MT induced multiplication at the highest concentration (10 μM) and BA produced the greatest number of plantlets (at 3.2 μM) with optimal multiplication at approximately 6 μM. Liquid medium did not affect multiplication rate when compared with agar, but plants were twice as large from
liquid as compared with those from agar at the time of transfer to the greenhouse. After …
