Planning, Implementation, And Formative Evaluation Of A Food Literacy Program, Heather M. Thomas

Electronic Thesis and Dissertation Repository

The overall purpose of this dissertation was to examine the planning, implementation, and formative evaluation of a community-based food literacy program for youth. Article 1 provided a summary of the community-based cooking program for at-risk youth. Objectives included the provision of applied food literacy and cooking skills education augmented with fieldtrips to local farms. Eight at-risk youth (five girls and three boys, mean age = 14.6) completed the intervention. Post intervention, five of eight participants completed in-depth interviews about their experiences.

Article 2 was a formative evaluation of the cooking program focused on gaining an understanding of participants’ (i.e., at-risk …

Dissociable And Dynamic Components Of Cognitive Control: A Developmental Electrophysiological Investigation, Matthew Waxer

Electronic Thesis and Dissertation Repository

One standard task used to investigate the development of cognitive control is the Dimensional Change Card Sort (DCCS). Performance and patterns of brain activity associated with the DCCS show continued age-related advances into early adolescence. According to many theoretical accounts, the DCCS places demands on a single underlying executive control process. Three experiments examined the possibility that the DCCS places demands on multiple control processes that follow distinct developmental trajectories. In Experiment 1, rule switching and conflict processing made orthogonal contributions to DCCS performance. Rule switching was associated with a cue-locked late frontal negativity (LFN) event-related potential (ERP) and conflict …

Development Of New Platforms For Efficient Production And Purification Of Recombinant Protein In Higher Plants, Reynald Tremblay

Electronic Thesis and Dissertation Repository

The world-wide demand for recombinant proteins continuously increases as new medical and industrial applications are developed. Higher plants have the potential to help meet this rising demand as green bioreactors. A major hurdle, however, is low recombinant protein yields in higher plants and, as with many production systems, high cost associated with downstream purification and the production of short peptides. The goal of this research was to address each of these problems to further increase the utility of plant bioreactors. The short antigenic peptide 277 (p277) from heat shock protein 60, which has the potential for use in the prevention …
