Murray State University, located in the city of Murray, Kentucky, is a four-year public university with more than 11,200 students. For 24 straight years Murray State University has been recognized by "U.S.News & World Report's Best Colleges" as one of the top regional universities in the United States. Murray State has consistently been the top-ranked public regional university in Kentucky. In addition to the main campus, Murray State University operates extended campuses offering upper level and graduate courses in Paducah, Hopkinsville, Madisonville, and Henderson. Wikipedia.

Biochemistry and Molecular Biology Education
This report describes the incorporation of digital learning elements in organic chemistry and biochemistry courses. The first example is the use of pen-based technology and a large-format PowerPoint slide to construct a map that integrates various metabolic pathways and control points. Students can use this map to visualize the integrated nature of metabolism and how various hormones impact metabolic regulation. The second example is the embedding of health-related YouTube videos directly into PowerPoint presentations. These videos become a part of the course notes and can be viewed within PowerPoint as long as students are online. The third example is the use of a webcam to show physical models during online sessions using web-conferencing software. Various molecular conformations can be shown through the webcam, and snapshots of important conformations can be incorporated into the notes for further discussion and annotation. Each of the digital learning elements discussed in this report is an attempt to use technology to improve the quality of educational resources available outside of the classroom to foster student engagement with ideas and concepts. © 2011 Wiley Periodicals, Inc.

Quaternary Science Reviews
Recent attempts to estimate the age of deposition of European fossil localities using mathematical equations derived from size change of the first lower molar in arvicolid rodent lineages as a function of time prompted an assessment of the value of this approach. The accuracy of "vole clocks" depends on accurate dating of a fossil system and establishment of a directional size change pattern through time in a given species from the dated system. Results of this review suggest that vole clocks have limited value for biochronology. In addition to several methodological and statistical problems with published studies, vole clocks in general are untenable because paleontological systems cannot resolve dating to the level of accuracy necessary to construct an accurate equation, size and shape change is never monotonic (constant velocity) in lineages, and size commonly reverses direction in lineages on all time scales. © 2014 Elsevier Ltd.

Environmental Modelling and Software
This study examines the benefits of nonlinear time series modelling to improve forecast accuracy of the El Niño Southern Oscillation (ENSO) phenomenon. The paper adopts a smooth transition autoregressive (STAR) modelling framework to assess the potentially smooth regime-dependent dynamics of the sea surface temperature anomaly. The results reveal STAR-type nonlinearities in ENSO dynamics, which results in the superior out-of-sample forecast performance of STAR over the linear autoregressive models. The advantage of nonlinear models is especially apparent in short- and intermediate-term forecasts. These results are of interest to researchers and policy makers in the fields of climate dynamics, agricultural production, and environmental management. © 2012 Elsevier Ltd. Source

A combination of dental and mandibular characters demonstrates that Chaline's vole, known from the Pleistocene of Spain and Italy, originally named as Allophaiomys chalinei and later referred by some authors to Arvicola and Tibericola, is unrelated to either Allophaiomys or Arvicola and probably is not closely related to Tibericola. It is here considered as the only member of a new genus, Victoriamys, named for the cave from which V. chalinei nov. comb. was first described. © 2012. Source

Murray State University (MSU) will implement an ADVANCE Institutional Transformation-Catalyst (IT-Catalyst) project to undertake institutional self-assessment activities. MSU will conduct surveys of faculty and interviews, review existing institutional data and policies, conduct site-visits to ADVANCE institutions, invite speakers to campus to inform and educate the administration and faculty, and conduct mentoring circles to support junior STEM faculty.
MSU provides a unique opportunity to examine the recruitment, retention and promotion of women faculty in STEM disciplines at a regional comprehensive and primarily undergraduate public university in rural western Kentucky. MSU serves a region that has been historically underserved in STEM education and has been challenged to recruit and retain female faculty and students in STEM. The Murray State University project will add to our understanding of the factors that impact women in a rural academic environment. This project may serve as a model for other rural regional universities where women faculty are commonly underrepresented in STEM.
The ADVANCE program is focused on developing systemic approaches to increase the participation, retention, and advancement of women in academic STEM careers. The IT-Catalyst track funds projects to conduct institutional self-assessments as well as implement strategies that have been shown to be effective to address gendered issues for STEM faculty.
