Innovations in Health Policy

Recent events have tested almost every aspect of our healthcare system, forcing us to think and act in bold new ways. Health policy is taking center stage, opening new conversations about what we can and should be doing in order to preserve health and protect our communities. With the benefit of this new perspective, it\u27s time to take a fresh look at policies regarding health insurance, reimbursement, social services and public health initiatives that support community health and education. Join our Interim Dean Billy Oglesby for a frank and lively discussion with health policy expert and our Emeritus Dean David B. Nash. Presentation: 58:1

Interactive Learning Tools: Animating Statics

Computer-Based Modules for Engineering Instruction Must Be Concise, Flexible, Educational and Engaging in Order to Effectively Supplement Traditional Classroom Teaching Tools. a Computer Example that Takes More Time Than a Chalkboard Presentation is Not Likely to Be Useful in Today\u27s Engineering Classroom. Flexible Navigation is Necessary So that the Instructor Can Quickly and Easily Respond to Student Questions. Useful Modules Must Also Improve Problem-Solving Skills or Clarify Troublesome Concepts in Order to Be Considered Worthy of Inclusion in the Limited Class Time Available. Finally, and Perhaps Most Importantly, Effective Computer-Based Modules Must Meet the Challenge of Holding the Student\u27s Attention. This Paper Focuses on the Development and Improvement of Computer-Based Interactive Modules for Statics Instruction. the Modules Were Created using an Animation Package (Flash®) So that Concepts Such as Sectioning of Trusses and the Generation of Shear and Moment Diagrams Can Be Presented in an Intuitive and Interactive Manner. the Modules Are Able to Represent Dynamic and Abstract Aspects of These Concepts in a Way that is Not Possible with Traditional Instructional Tools. the Paper Also Discusses the Use of Feedback from Instructors and Students to Improve the Interactivity and Scope of the Modules

Incorporating Web-Based Homework Problems in Engineering Dynamics

We are involved in a project funded by the Department of Education (FIPSE) which focuses on developing interactive software to improve the teaching and learning of engineering statics, dynamics, and mechanics of materials. This paper presents an overview of this project, discusses its objectives, and focuses on one particular aspect of the project.the use of web-based homework problems as assessment tools to evaluate student learning. The overall project includes creating, for all three engineering mechanics courses, the following web-based learning tools: (a) Animated theory modules, using Macromedia.s Flash development software, which display basic theory and example problems in an engaging, clear, and concise way; (b) Conceptual quizzes to evaluate student understanding of the theory; (c) Web-based homework problems to assess students. quantitative skills; (d) Other media elements, including streaming video mini-lectures over key topics, and video of real mechanisms and examples. The paper will give examples of web-based homework used in dynamics, discuss aspects of creating and using these, and give some results of student feedback from using these problems

Accrediting Graduate Programs in Healthcare Quality and Safety

The number of master\u27s degree programs in healthcare quality and safety (HQS) has increased significantly over the past decade. Academic accreditation provides assurance that educational programs are of a high quality and meet the needs of students, employers, and the general public. Under the guidance of the Commission on Accreditation of Healthcare Management Education, faculty from 9 universities collaborated in the development of criteria and related content domains to be used in the accreditation of graduate programs in HQS. Thirteen content domains were identified. Four of the content domains, safety and error science, improvement science and quality principles, evidence-based practice, and measurement and process improvement are thought to be foundational domains for graduate education in HQS. This article describes the development of the content domains and accompanying standards for accreditation of graduate programs in HQS

An Integrated Approach for Finding Overlooked Genes in Shigella

Background: The completion of numerous genome sequences introduced an era of whole-genome study. However, many genes are missed during genome annotation, including small RNAs (sRNAs) and small open reading frames (sORFs). In order to improve genome annotation, we aimed to identify novel sRNAs and sORFs in Shigella, the principal etiologic agents of bacillary dysentery. Methodology/Principal Findings: We identified 64 sRNAs in Shigella, which were experimentally validated in other bacteria based on sequence conservation. We employed computer-based and tiling array-based methods to search for sRNAs, followed by RT-PCR and northern blots, to identify nine sRNAs in Shigella flexneri strain 301 (Sf301) and 256 regions containing possible sRNA genes. We found 29 candidate sORFs using bioinformatic prediction, array hybridization and RT-PCR verification. We experimentally validated 557 (57.9%) DOOR operon predictions in the chromosomes of Sf301 and 46 (76.7%) in virulence plasmid.We found 40 additional co-expressed gene pairs that were not predicted by DOOR. Conclusions/Significance: We provide an updated and comprehensive annotation of the Shigella genome. Our study increased the expected numbers of sORFs and sRNAs, which will impact on future functional genomics and proteomics studies. Our method can be used for large scale reannotation of sRNAs and sORFs in any microbe with a known genom

Atlantic and Pacific SST influences on Medieval drought in North America simulated by the Community Atmospheric Model

Severe drought is arguably one of the greatest recurring natural disasters that strikes North America. A synthesis of multiproxy data shows that North America was in the grip of a severe centennial-scale drought during medieval times (800–1300 AD). In this study, the Community Atmospheric Model (CAM) is used to investigate the role of sea surface temperature (SST) anomalies from the North Atlantic and the tropical Pacific Ocean on this megadrought. These anomalies are obtained from proxy reconstructions of SST. Four model experiments with prescribed SST anomalies in the tropical Pacific and/or North Atlantic Ocean were made. The CAM results captured the major dry features that occurred during medieval times in North America. The cold tropical Pacific alone can simulate essentially the drought intensity, while the warm North Atlantic alone can simulate the drought areal extent. The two working together can explain the severity and longevity of the drought. During the spring season, the cool tropical Pacific, or the warm North Atlantic, or both, results in less moisture transport to the High Plains, with a 15– 40% decrease in rainfall. The importance of the Atlantic Ocean on medieval drought in North America suggests that attention should be paid not only to the tropical Pacific Ocean but also to the North Atlantic Ocean in understanding the North America drought variability and predictability, both at present and during the past. This is especially true because the Pacific Ocean SST anomalies in medieval times as recorded by proxy data are somewhat controversial, while the North Atlantic anomalies seem more certain

Large Wind Shift on the Great Plains during the Medieval Warm Period

Spring-summer winds from the south move moist air from the Gulf of Mexico to the Great Plains. Rainfall in the growing season sustains prairie grasses that keep large dunes in the Nebraska Sand Hills immobile. Longitudinal dunes built during the Medieval Warm Period (800 to 1000 years before the present) record the last major period of sand mobility. These dunes are oriented NW-SE and are composed of cross-strata with bipolar dip directions. The trend and structure of the dunes record a drought that was initiated and sustained by a historically unprecedented shift of spring-summer atmospheric circulation over the Plains: Moist southerly flow was replaced by dry southwesterly flow.

Inconsistencies Between Pangean Reconstructions and Basic Climate Controls

The supercontinent Pangea dominated our planet from the Permian into the Jurassic. Paleomagnetic reconstructions have been used to estimate the latitudinal position of Pangea during this 100-million-year period. Atmospheric circulation, recorded by eolian sandstones in the southwestern United States, shows a broad sweep of northeasterly winds over their northernmost extent, curving to become northwesterly in the south. This evidence is consistent with paleomagnetic reconstructions of the region straddling the equator in the Early Permian but is at odds with its northward movement to about 20°N by the Early Jurassic. At least one of the following scenarios must be true: the latitude based on paleomagnetism is incorrect; the interpretation of how winds shaped the dunes is mistaken; the basic climate controls in the Jurassic were different from those of today; or the paleogeographic reconstructions available are insufficient to adequately reproduce the wind fields responsible for dune formation
