Learning to Teach Science from a Contextualized Stance

Creator:: L’Heureux, K., Giamellaro, M., Beaudry, M-C., Buxton, C., Ayotte-Beaudet, J-P., and Alajmi, T.
Abstract:: Contextualization is a curricular approach and a learning process in which science content knowledge is intentionally situated within a context where that knowledge can be authentically applied or observed. Many recent science education reforms include contextualization as a central tenet. Our goal in this review was to examine commonalities across...

Studies on DNA precursor metabolism in vaccinia virus-infected mamalian cells

Creator:: Spiro, Craig
Abstract:: Vaccinia virus-infected animal cells have been used to study the interactions between the replication of deoxyribonucleic acid (DNA) and the biosynthesis of its nucleotide precursors. Some antimetabolites that inhibit DNA replication have as their targets enzymes of nucleotide biosynthesis. Furthermore, the disruption of nucleotide metabolism can alter the fidelity of...

Deoxyribonucleotides as determinants of DNA replication fidelity in bacteriophage T4

Creator:: Sargent, Roy Geoffrey
Abstract:: Imbalanced deoxyribonucleoside triphosphate (dNTP) pools are mutagenic for DNA synthesis in both intact cells and cell-free replication systems. Almost certainly, such mutagenesis involves competition between correctly and incorrectly base-paired precursors at replication sites. However, there are certain differences between the intact cell and cell-free systems that do not always allow...

Coastal vulnerability across the Pacific dominated by El Niño/Southern Oscillation

Creator:: Barnard, Patrick L., Short, Andrew D., Harley, Mitchell D., Splinter, Kristen D., Vitousek, Sean, Turner, Ian L., Allan, Jonathan, Banno, Masayuki, Bryan, Karin R., Doria, André, Hansen, Jeff E., Kato, Shigeru, Kuriyama, Yoshiaki, Randall-Goodwin, Evan, Ruggiero, Peter, Walker, Ian J., and Heathfield, Derek K.
Abstract:: To predict future coastal hazards, it is important to quantify any links between climate drivers and spatial patterns of coastal change. However, most studies of future coastal vulnerability do not account for the dynamic components of coastal water levels during storms, notably wave-driven processes, storm surges and seasonal water level...

Evidence for Strengthening Hadley Cells and a Westward Expansion of the Walker Circulation from Assimilation of Paleoclimate Proxy Data

Creator:: Horlick, Kaleb A.
Abstract:: A synthesis of over 2000 paleoclimate proxy records is performed via a data assimilation framework that expands upon previous efforts by implementing a suite of physically-based proxy system models, and which provides the first example of an observationally independent, multi-seasonal (DJFM, JJAS) paleoclimate reanalysis. This methodology is contrasted against previous...

Internal Variability in Projections of Twenty-First-Century Arctic Sea Ice Loss: Role of the Large-Scale Atmospheric Circulation

Creator:: Wettstein, Justin J. and Deser, Clara
Abstract:: Internal variability in twenty-first-century summer Arctic sea ice loss and its relationship to the large-scale atmospheric circulation is investigated in a 39-member Community Climate System Model, version 3 (CCSM3) ensemble for the period 2000–61. Each member is subject to an identical greenhouse gas emissions scenario and differs only in the...

Analysis of the present and future winter Pacific-North American teleconnection in the ECHAM5 global and RegCM3 regional climate models

Creator:: Allan, Andrea M., Hostetler, Steven W., and Alder, Jay R.
Abstract:: We use the NCEP/NCAR Reanalysis (NCEP) and the MPI/ECHAM5 general circulation model to drive the RegCM3 regional climate model to assess the ability of the models to reproduce the spatiotemporal aspects of the Pacific-North American teleconnection (PNA) pattern. Composite anomalies of the NCEP-driven RegCM3 simulations for 1982–2000 indicate that the...

Variations in Gas and Water Pulses at an Arctic Seep: Fluid Sources and Methane Transport

Creator:: Hong, Wei-Li, Torres, Marta E., Portnov, A., Waage, M., Haley, B., and Lepland, A.
Abstract:: Methane fluxes into the oceans are largely dependent on the methane phase as it migrates upward through the sediments. Here we document decoupled methane transport by gaseous and aqueous phases in Storfjordrenna (offshore Svalbard) and propose a three-stage evolution model for active seepage in the region where gas hydrates are...

State of the California Current 2010-2011: Regionally Variable Responses to a Strong (But Fleeting?) La Nina

Abstract:: The state of the California Current system (CCS) since spring 2010 has evolved in response to the development of cooler La Nina following the dissipation of the relatively weak and short-lived El Nino event of 2009-2010. The 2009-2010 El Nino appears to have dissipated quite rapidly in early spring 2010,...
