With the increased attention on need to retain students within STEM majors, it is important for instructors adopt evidence-based instructional practices that are student-centric and employ active learning techniques. However, traditional approaches increasing student-centric, such as workshops, seminars, department or college mandates have been either inefficient ineffective at motivating institutional change. This particularly true introductory courses with large enrollments. One promising...

The incision of rivers in bedrock is thought to be an important factor that influences the evolution relief tectonically active orogens. At present, there are at least six competing models for rivers, but these have received little quantitative testing. We statistically evaluate using observations from Clearwater River northwestern Washington State, which crosses actively rising forearc high Cascadia margin. A previous study has used fluvial terraces along estimate rates over last ∼150 kyr....

This paper makes the claim that legal framework governing European Stability Mechanism (ESM) is contradictory, conceptually incoherent and may be characterized as a circumvention of Union law. It further claimed such circumvention, resulting establishment significant permanent institution outside beyond scope order, represents challenge to democracy principle respect for rule

A surface processes model incorporating large-scale fluvial processes, local hill-slope and glacial erosion is used to investigate the effect of glaciation on relief a fast-growing, narrow orogen. The results several simulations show that: glaciers concentrate near peaks; reduced downstream glaciers; with frozen bases can lead an increase in relief; net affect absence widespread basal freezing reduce relief.

Abstract We have developed a new surface-processes model incorporating large-scale fluvial processes, local hill-slope processes and glacial erosion. Ice thickness velocity are calculated under shallow-ice approximation. Simulation experiments in fast-growing orogens comparing the efficiencies of erosion, where two operating simultaneously over several cycles, show that: landscapes can support greater ice masses than landscapes; valley lake shapes create disequilibrium between landform...

This research investigates the impact professors, and other instructional staff, have on student content knowledge acquisition in a physical science MOOC offered through University of Illinois at Urbana-Champaign. An A/B test was used to randomly assign participants either control group (with no interaction) or an intervention (in which professor teaching assistants responded comments discussion complied summary weekly feedback statements) identify differences learning outcomes,...

Stakeholders are increasingly calling for improving instruction in STEM by building environments that enable faculty to sustainably change their teaching practices. This study reports one institutional effort effectively facilitated faculty's adoption of evidence-based instructional practices (EBIP), which is organize into teaching-focused communities practice (CoPs). We examined the social interactions within CoPs and investigated whether were actively adopting EBIP (adopting CoPs) had more...

Abstract Background Grades in college and university STEM courses are an important determinant of student persistence fields. Recent studies have used the grade offset/grade penalty method to explore why students lower grades than their GPAs would predict. The results these doubt; however, as they use GPA a reliable measure academic performance, which is disputed assumption. Using predictive model it possible produce more accurate performance observed discover if graded stringently, under...

Climate change indirectly alters the distribution of tectonic uplift at active orogens by modifying action surface processes, which in turn mountain topography. The impact alpine glaciation on activity is explored here. predictions previous analytical, critical wedge models are compared with output a numerical model that explicitly couples rock produced convergence erosion. Glacial and fluvial erosive processes calculated over two‐dimensional grid, uses an ice evolution to calculate rate...

Although Evidence-Based Instructional Practices (EBIP) generally improve students' performance in STEM, traditional lecturing remains the most common instructional practice postsecondary settings. This study examines an institutional change program that organized STEM faculty into communities of (CoPs) to facilitate adoption and spread EBIP classrooms. In this program, CoPs were mentored by members who have a track record as advocates for high-quality teaching. order practices spread,...

Radiocarbon dating of the two LSU Campus Mounds (16EBR6) indicates that construction one, Mound B, began at ∼11,000 BP, making B oldest known and intact manmade structure in Americas. The age analyses presented here are based on thirty one ^14^C dates. older (deeper) parts both contain many thin, burned ash lenses, suggesting may have been used for ceremonial or cremation purposes. These layers composed mainly phytoliths, bio-silicate (SiO~2~) structural compounds plants remained after...

Abstract Applying time-series analyses using Fourier transform and multi-taper methods to low-field, mass-specific magnetic susceptibility (χ) measurements on marine samples from well-studied shale limestone outcrops of the Upper Ordovician (Edenian Stage; Katian) Kope Formation, northern Kentucky, corroborates direct visual identification in Milankovitch eccentricity ( c. 405 100 ka), obliquity precessional climate cycles.
