The Growth Mindset Approach: A Threshold Concept in Course Redesign
Get PDFGrowth mindset (Dweck, 2006) is the simple but powerful belief that intelligence is not fixed, but dynamic, and can develop over time. When faculty and students embrace the idea that learning is elastic, it permanently transforms how we approach learning and, thus, is a “Threshold Concept,” a transformative and irrevocable way of thinking about something (Meyer, Land, & Cousin, 2006). This combined approach to course design workshops (growth mindset and threshold concepts) provides a lens through which educational developers can work with students and colleagues because it illuminates bottlenecks or sticking points for faculty in the course design process and helps them shift their focus away from content delivery to active, transformative learning. The author argues that the growth mindset approach is a powerful concept in learning and educational development, describes specific workshop activities that help promote a growth mindset for faculty, and contends that such an approach represents a threshold concept for them and, thus, their students.PublishedYe
Altered microRNA Expression Profiles and Regulation of INK4A/CDKN2A Tumor Suppressor Genes in Canine Breast Cancer Models
Get PDFmicroRNA (miRNA) expression profiling of cancer versus normal cells may reveal the characteristic regulatory features that can be correlated
to altered gene expression in both human and animal models of cancers. In this study, the comprehensive expression profiles of the 277 highly
characterized miRNAs from the canine genome were evaluated in spontaneous canine mammary tumor (CMT) models harboring defects in a
group of cell cycle regulatory and potent tumor suppressor genes of INK4/CDKN2 family including p16/INK4A, p14ARF, and p15/INK4B. A
large number of differentially expressed miRNAs were identified in three CMT cell lines to potentially target oncogenes, tumor suppressor
genes and cancer biomarkers. A group of the altered miRNAs were identified by miRNA target prediction tools for regulation of the INK4/
CDKN2 family tumor suppressor genes. miRNA-141 was experimentally validated for INK4A 30
-UTR target binding in the CMT cell lines
providing an essential mechanism for the post-transcriptional regulation of the INK4A tumor suppressor gene in CMT models. A wellrecognized group of miRNAs including miR-21, miR-155, miR-9, miR-34a, miR-143/145, and miR-31 were found to be altered in both CMTs
and human breast cancer. These altered miRNAs might serve as potential targets for advancing the development of future therapeutic reagents.
These findings further strengthen the validity and use of canine breast cancers as appropriate models for the study of human breast cancers.PublishedYe
One- and two-dimensional hybrid simulations of whistler mode waves in a dipole field
Get PDFWe simulate whistler mode waves using a hybrid code. There are four species in the simulations, hot electrons initialized with a bi-Maxwellian distribution with temperature in the direction perpendicular to background magnetic field greater than that in the parallel direction, warm isotropic electrons, cold inertialess fluid electrons, and protons as an immobile background. The density of the hot population is a small fraction of the total plasma density. Comparison between the dispersion relation of our model and other dispersion relations shows that our model is more accurate for lower frequency whistlers than for higher frequency whistlers. Simulations in 2-D Cartesian coordinates agree very well with those using a full dynamics code. In the 1-D simulations along the dipole magnetic field, the predicted frequency and wave number are observed. Rising tones are observed in the one-fourteenth scale simulations that have larger than realistic magnetic field spatial inhomogeneity. However, in the full-scale 1-D simulation in a dipole field, the waves are more broadband and do not exhibit rising tones. In the 2-D simulations in a meridional plane, the waves are generated with propagation approximately parallel to the background magnetic field. However, the wavefronts become oblique as they propagate to higher latitudes. Simulations with different plasma density profiles across L shell are performed to study the effect of the background density on whistler propagation.PublishedYe
Teaching Infographic Source Evaluation to Biology Majors
No full textInfographics are an effective means of communicating information quickly and impactfully. They are often used to present complex datasets and statistics that otherwise would be difficult to digest. This makes them valuable information resources, but their very simplicity makes them capable of leading viewers to dramatically different conclusions about the same information. As such, infographic source evaluation is an important component of information literacy, particularly important in the sciences, where graphic representations of data and statistics are the norm; however, it is often overlooked. We (science librarian and Biology professor) collaborated to develop two infographic source evaluation sessions embedded into an epidemiology-themed course for freshman Biology majors. We had two goals for these sessions: 1) Students would be able to apply evaluative criteria to infographic sources in order to judge accuracy, bias, and quality of infographics; and 2) students would be able to locate appropriate scientific data sources in order to create their own infographics. In our poster presentation, we will share information on the development of the classes, the activities and materials we used, class outcomes, and the benefits to students, faculty member, and librarian.Ye
Do Long Embargo Periods Facilitate External Publication of Electronic Theses and Dissertations?
No full textEmbargo periods for Electronic Thesis and Dissertations (ETDs) collections require librarians to balance the needs of content creators (ETD authors) with those of content consumers (end-users). This poster examines the local impact of the American Historical Association's July 2013 policy statement recommending a six-year embargo for history dissertations to facilitate external publication. Embargo selections by local PhD candidates in history and political science are compared for periods before and after this statement was issued. External publication rates and average length of time prior to publication are compared for embargoed and non-embargoed titles.Presente
Framework for identifying implemenation issues affecting extension human science programming: Supplemental References
No full textIntroducing ePortfolios to Construction Management Undergraduate Students
Get PDFEffective communication is one of the essential skills for construction students. This paper describes an innovative model of a professional digital portfolio (ePortfolio) program in an ACCE accredited construction management undergraduate program. The objectives of this ePortfolio program include improving students’ communication skills, improving their writing and critical thinking skills, and helping them become more competitive on the job market upon graduating. This program implements ePortfolio into the curriculum by using ePortfolio related project assignments in selected junior and senior level courses and requiring student to have a fully developed and up-to-date professional ePortfolio at the time they graduate. This program uses a student questionnaire survey to assess its effectiveness. The results of the assessment indicate that this ePortfolio program has made some positive impacts to the curriculum and enhanced students’ learning experience.PublishedYe
