Neural Correlates Of The Development Of Cognitive Flexibility, Dina R. Dajani
Neural Correlates Of The Development Of Cognitive Flexibility, Dina R. Dajani
Open Access Theses
One aspect of executive function, cognitive flexibility, is necessary for implementing the appropriate and efficient adaptation of cognitions in the face of changing environments. In a recently proposed framework, cognitive flexibility is thought to involve multiple component functions: stimulus-driven attention and two related executive functions, working memory and inhibition. These executive functions commonly recruit the frontal, cingulate, and parietal brain regions, but it is unclear whether cognitive flexibility and its component functions arise from specific connectivity profiles within this superordinate fronto-cingulo-parietal network. The objectives of this study were to 1) index behavioral changes in attention, working memory, inhibition and cognitive …
Identification And Characterization Of The Molecular Determinants Of The Anterior-Posterior Axis In The Sea Urchin Embryo, Lingyu Wang
Open Access Dissertations
How the embryonic body axis emerges from a seemingly symmetrical egg and is subsequently patterned during embryogenesis is one of the most fundamental questions in developmental biology. It is now clear that localized activation of the Wnt/β-catenin signaling pathway plays a conserved role in primary body axis formation and/or endoderm/endomesoderm specification during embryo development of phylogenetically diverse animal species. In sea urchin embryos, recent experimental evidence has shown that Dishevelled (Dsh), a central hub protein in the Wnt/β-catenin pathway, is asymmetrically enriched and differentially modified in a vegetal cortical domain (VCD) of the unfertilized egg. Experimental evidence has also shown …
A Developmental Theory Analysis Of The Puerto Rican Popular Democratic Party's (Ppd) Economic Policy, Armando A. Torres Alfonso
A Developmental Theory Analysis Of The Puerto Rican Popular Democratic Party's (Ppd) Economic Policy, Armando A. Torres Alfonso
Open Access Theses
The Puerto Rican Popular Democratic Party’s (PPD) 2012 governmental platform and interviews with party officials were evaluated from the perspective of developmental theories, including Amartya Sen’s Capabilities Approach, Neoliberalism and Developmentalism. This study aimed to determine whether the international prevalence of a gap between developmental theory and practice is reflected in the case of economic policymaking in Puerto Rico. The key finding is that the PPD is ambivalent on developmental theory and, as a result, promotes both Developmentalist and Neoliberal policies, with a greater emphasis on the latter. Further, this mixing of theories could explain developmental inefficiency and/or failure. A …
