Origin of the T enhancement in heterostructure cuprate superconductors
Recent experiments on heterostructures composed of two or more films of
cuprate superconductors of different oxygen doping levels\cite{Yuli,Gozar} have
shown a remarkable T enhancement (up to 50%) relative to single compound
films. We provide here a simple explanation of the enhancement which arises
naturally from a collection of experimental works. We show that the enhancement
could be caused by a structural change in the lattice, namely an increase in
the distance of the apical oxygen from the copper-oxygen plane. This increase
modifies the effective off-site interaction in the plane which in turn enhances
the d-wave superconductivity order parameter. To illustrate this point we study
the extended Hubbard model using the fluctuation exchange approximation
Draft genomes of two strains of flavobacterium isolated from lake washington sediment.
We report sequencing the genomes of two new Flavobacterium strains isolated from Lake Washington sediment. From genomic contents, versatile lifestyles were predicted but not bona fide methylotrophy. With the availability of their genomic sequences, the new Flavobacterium strains present prospective models for studying microbial communities in lake sediments
Draft Genome of Pseudomonas sp. Strain 11/12A, Isolated from Lake Washington Sediment.
We announce here the genome sequencing of Pseudomonas sp. strain 11/12A from Lake Washington sediment. From the genome content, a versatile lifestyle is predicted but not one of bona fide methylotrophy. With the availability of its genomic sequence, Pseudomonas sp. 11/12A presents a prospective model for studying microbial communities in lake sediments
Catalyst for Democracy? Outcomes and Processes in Community-University Interaction
Regional colleges and universities are unique in their historic commitment to serve the economic, social, and cultural interests of particular communities. Drawing on the findings of a multi-site case study of two regional institutions, this paper outlines the goals of community-university interaction, then focuses more specifically on the processes of collaboration as distinct from the participants’ desired outcomes. Separating goals from process in this way allows us to explore the civic/democratic impact of these initiatives beyond their economic impact. Findings suggest that when community-university engagement initiatives focus too narrowly on economic development goals, project leaders sometimes neglect the potential of engagement initiatives as catalysts for participatory democracy, thereby limiting input from traditionally under-represented groups. Scholars and practitioners can draw from community development literature, as well as the scholarship related to community-university engagement, allowing simultaneous attention to the nature of relationships between universities and the communities they serve and the process of building inclusive relationships
Draft Genome of Janthinobacterium sp. RA13 Isolated from Lake Washington Sediment.
Sequencing the genome of Janthinobacterium sp. RA13 from Lake Washington sediment is announced. From the genome content, a versatile life-style is predicted, but not bona fide methylotrophy. With the availability of its genomic sequence, Janthinobacterium sp. RA13 presents a prospective model for studying microbial communities in lake sediments

A STUDY OF PERCEPTIONS OF MATH MINDSET, MATH ANXIETY, AND VIEW OF MATH BY YOUNG ADULTS
This study’s purpose was to determine whether instruction in growth math mindset led to change in perceptions of 18-22-year-old at-risk students in math mindset, math anxiety, and view of math. The experimental curriculum was created by the researcher with the guidance of experts in mathematics and education and focused on the impact of brain growth and learning supported by positive math mindset. Young adult public charter high school at-risk students were surveyed before and after completion of the experimental intervention to measure their perceptions in the domains of Math Mindset, Math Anxiety, and View of Math. The results revealed significant differences in the treatment group’s pre-to post-test perceptions in all three math domains (p \u3c .001) Comparison between the experimental and control groups were conducted, revealing significant differences between the two group in all three domains of math. These results point to the effectiveness of the experimental curriculum and instructional techniques to positively impact students’ perceptions of Math Mindset, reduction of Math Anxiety, and improvement in View of Math
