Catastrophe Models for Cognitive Workload and Fatigue

We reconceptualised several problems concerning the measurement of cognitive workload – fixed versus variable limits on channel capacity, work volume versus time pressure, adaptive strategies, resources demanded by tasks when performed simultaneously, and unclear distinctions between workload and fatigue effects – as two cusp catastrophe models: buckling stress resulting from acute workload, and fatigue resulting from extended engagement. Experimental participants completed a task that was intensive on non-verbal episodic memory and had an automatically speeded component. For buckling stress, the epoch of maximum (speeded) performance was the asymmetry parameter; however, anxiety did not contribute to bifurcation as expected. For fatigue, the bifurcation factor was the total work accomplished, and arithmetic, a compensatory ability, was the asymmetry parameter; R2 for the cusp models outperformed the linear comparison models in both cases. A research programme is outlined that revolves around the two models with different types of task and resource configurations

Food & Community – OSU Extension Local Foods Signature Program

IMPACT. 1: Buying local foods has a ripple effect on the economy. The farmer/producer benefits as well as their employees, local businesses they frequent, charities they support and the local tax base. -- 2. Food raised on local farms not only reduces pollution from long-distance transportation, but also helps to protect our water sources, conserve nutrient-rich soil and provide habitat for local wildlife. -- 3. Over two million Ohioans are food insecure. Community gardens, farm markets, food banks and simply sharing your extra garden produce can feed these families and connect them to the community.OSU PARTNERS: College of Food, Agricultural and Environmental Sciences; OSU Extension; Department of Food Science and Technology; Ohio Agricultural Research and Development Center; College of Engineering; Department of Food, Biological and Agricultural Engineering; College of Education and Human Ecology; Department of Human Sciences; Ohio AgrAbility Program; John Glenn School of Public Affairs; Knowlton School of ArchitectureCOMMUNITY PARTNERS: Americorps VISTA; Appalachian Center for Economic Networks (ACEnet); Godman Guild Association; Innovative Farmers of Ohio; Local Matters; Mid-Ohio Regional Planning Commission; Ohio Department of Agriculture Ohio Ecological Food and Farming Association; Ohio Farm Bureau; Ohio Farmers' Market Management Network; Ohio Market Maker; Rural Action Council of Ohio Sustainable Agriculture Research and Education ProgramPRIMARY CONTACT: Kate Shumaker ([email protected])Farm to Plate. Thirty Mile Meals. Feeding our friends and neighbors, funding the local economy and improving the environment can all be accomplished by participating in the local foods movement. Ohio State University Extension's Local Foods Signature Program addresses the critical need for outreach education around the broad topic of local food systems. One of our themes, Food and Community, features education connecting local food to community gardens, farmers markets, food banks and schools

Food & Family – OSU Extension Local Foods Signature Program

IMPACT. 1: Over two million Ohioans are food insecure. Connecting these families with local food resources and teaching them how to grow/raise their own food can help them be more secure. -- 2. Food is at the center of many traditions. Recognizing and celebrating the role of food in familial, regional, ethnic, and religious customs can bring communities together. -- 3. Family meals are highly connected to healthier choices. Families who eat meals together tend to consume more fruits, vegetables and fiber, and less fried/fatty foods and empty calories.OSU PARTNERS: College of Food, Agricultural and Environmental Sciences; OSU Extension; Department of Food Science and Technology; Ohio Agricultural Research and Development Center; College of Engineering; Department of Food, Biological and Agricultural Engineering; College of Education and Human Ecology; Department of Human Sciences; Ohio AgrAbility Program; John Glenn School of Public Affairs; Knowlton School of ArchitectureCOMMUNITY PARTNERS: AmeriCorps VISTA; Appalachian Center for Economic Networks (ACEnet); Godman Guild Association; Innovative Farmers of Ohio; Local Matters; Mid-Ohio Regional Planning Commission; Ohio Department of Agriculture Ohio; Ecological Food and Farming; Association; Ohio Farm Bureau; Ohio Farmers' Market Management Network; Ohio MarketMaker; Rural Action Council of Ohio; Sustainable Agriculture Research and Education Program; United Way of Central OhioPRIMARY CONTACT: Kate Shumaker ([email protected])Food serves many roles in a family. It's more than sustenance. Food is a way to connect, to show love, to celebrate or honor, to teach, and more.

One of our themes, Food and Family, features education centered on nutrition, food safety, food preservation, food budgeting, wellness, and developing healthy lifestyle choices
