Impact of Home Field Advantage: Analyzed Across Three Professional Sports

We examined the impact of home-field advantage in the NFL, NBA, and MLB. We defined home-field advantage as winning more than 50% of the home games. Additionally, we took into consideration how season length could act as a moderator and influence the impact of home-field advantage. We collected data from the 2015 NBA and MLB seasons and the 2015 and 2016 NFL seasons to determine statistical significance. In total, we got data from 4,141 games to analyze. We found that there is statistical significance that the home team has a better chance of winning than the away team across the NFL, NBA, and MLB. We also found that season length has a significant impact on home team winning percentage

Music instrument teachers in higher education: an investigation of the key influences on how they teach in the studio

In higher education music instrument teaching, there is a strong tradition of high-level performers being recruited to teach advanced students within the private studio despite the fact these educators often have no training in pedagogy. The studio environment also continues to be dominated by the one-to-one lesson format and the master-apprentice tradition. While the literature overviews a long history of the master-apprentice tradition in various fields, there is to date minimal empirical research that specifically evidences the extent to which it is cyclical in nature. This paper reports on survey data from 54 current tertiary educators across four countries who were asked to identify the key influences on how they work within the music studio. The data point not only to the influence of the master-apprentice tradition, but also to the fact that most current educators rely on previous teachers and experiences of teaching to inform their pedagogy

Using Stimulated Recall and Reflection on Action with Music Studio Teachers in Higher Education

This article focuses on the issue of reflection for music studio teachers in higher education. Although stimulated recall and reflection on action are well-developed research fields in classroom education settings, the application of these methods to studio teaching is rare, a form of pedagogy which is heavily influenced by the master–apprentice tradition, with many teachers engaging in this practice without any formal training. The article presents the findings associated with three different studio pedagogues reflecting on video recordings of their lessons via cooperative analysis. Each of the three pedagogues took part in a live session with the researchers where their practice and methods were considered and discussed in significant detail, applying the principles of stimulated recall and shared reflections. Findings reveal that in addition to the need for inexperienced teachers to be courageous in reviewing their own work, stimulated recall and reflection on action offer benefits for teachers by assisting them in identifying areas of their practice to revise and re-examine. The findings therefore propose that the process of stimulated recall may be a useful component of professional development for teachers in the higher education sector

False discovery rate regression: an application to neural synchrony detection in primary visual cortex

Many approaches for multiple testing begin with the assumption that all tests in a given study should be combined into a global false-discovery-rate analysis. But this may be inappropriate for many of today's large-scale screening problems, where auxiliary information about each test is often available, and where a combined analysis can lead to poorly calibrated error rates within different subsets of the experiment. To address this issue, we introduce an approach called false-discovery-rate regression that directly uses this auxiliary information to inform the outcome of each test. The method can be motivated by a two-groups model in which covariates are allowed to influence the local false discovery rate, or equivalently, the posterior probability that a given observation is a signal. This poses many subtle issues at the interface between inference and computation, and we investigate several variations of the overall approach. Simulation evidence suggests that: (1) when covariate effects are present, FDR regression improves power for a fixed false-discovery rate; and (2) when covariate effects are absent, the method is robust, in the sense that it does not lead to inflated error rates. We apply the method to neural recordings from primary visual cortex. The goal is to detect pairs of neurons that exhibit fine-time-scale interactions, in the sense that they fire together more often than expected due to chance. Our method detects roughly 50% more synchronous pairs versus a standard FDR-controlling analysis. The companion R package FDRreg implements all methods described in the paper

The Homestead of James Taylor White II: Historical, Archaeological, and Geophysical Investigations at Two Proposed Safety Rest Areas, Interstate Highway (IH) 10, Chambers County, Texas

Personnel from Coastal Environments, Inc. (CEI), Moore Archeological Consulting, Inc. (MAC), and the University of Mississippi conducted archaeological and geophysical investigations at the locations of two proposed safety rest areas on opposite sides of Interstate Highway (IH) 10 in Chambers County, Texas. The research was carried out from late August 2006 until late February 2007, under contract to the Environmental Affairs Division of the Texas Department of Transportation (TxDOT). MAC archaeologists had previously examined the two rest area tracts in 2001. Their research indicated that the north tract contained a late-nineteenth- through early-twentieth-century cemetery, identified as the Broussard Cemetery site (41CH370). Buried within the cemetery are the remains of several members of the locally prominent White family and relatives. The south tract included the remains of a below-ground cistern that likely marked the location of the main house associated with the homestead and ranch of James Taylor White II. It was estimated that this house location, labeled the White Family Cistern site (41CH371), was occupied from ca. 1854 until sometime in the early 1900s. The field investigations examined three specific areas within the two tracts: (1) A small 20-by-45-m area situated about 10 m north of the Broussard Cemetery site where a truck-entrance road is to be built. It was considered possible that unmarked graves located outside the cemetery proper might be present in that area. (2) A 40-by-40-m area within the south tract where MAC personnel had located a piece of whiteware during their earlier investigations. It was thought that a possible outbuilding related to the White homestead might be present in that area. (3) A 110-by-115-m area in the south tract where the main house and most of the White family occupation occurred. The area in the north tract was examined by ground-penetrating radar, resistivity surveys and mechanical stripping of anomalies recognized by the geophysical research. The small square area in the south tract was examined by systematic shovel tests. The large area in the south tract was investigated by systematic shovel tests, a metal detector survey, a geophysical search that included magnetometer and electromagnetic susceptibility surveys, a limited ground-truth assessment of selected anomalies that had been identified by the geophysical surveys, mechanical stripping of other anomalies recognized by the geophysical research, plus the controlled excavation of a few small units in locations where the stripping uncovered potential cultural features. Overall, the various investigations identified the location, orientation, and dimensions of the White family house and its associated kitchen, a rich sheet midden situated to the rear of the house, and several possible outbuildings located to the sides of the structure. Numerous artifacts indicative of the period of suspected occupation were collected, including hundreds of pieces of metal, ceramic fragments, and glass. A few animal bones and plant remains also were obtained. Although the present study did not call for a detailed analysis of these items, such should prove useful in the future. Given these results, it is clear that site 41CH371 is eligible for inclusion in the National Register of Historic Places. Additional archaeological investigations at selected portions of the site are recommended, along with further archival and historical research. Accordingly, construction of the rest area in the south tract should be delayed until the recommended investigations are completed. The small area examined in the north tract near site 41CH370 failed to yield any evidence of burials. Since the cemetery itself will be avoided during construction, no further archaeological work is considered necessary in the north tract. Thus, construction of the rest area within the north tract may proceed as planned

Treating Central Catheter–Associated Bacteremia Due to Methicillin-Resistant Staphylococcus aureus: Beyond Vancomycin

Methicillin-resistant Staphylococcus aureus is a frequent cause of hospital-associated infections, including central catheter-associated bacteremia. Vancomycin has been the drug of choice for treating this type of bacteremia for decades in patients who have no contraindications to the antibiotic. However, resistance to vancomycin is an emerging problem. Newer antibiotics approved by the Food and Drug Administration have activity against methicillin-resistant S aureus Some of the antibiotics also have activity against strains of S aureus that are intermediately susceptible or resistant to vancomycin. This article uses a case study to highlight the clinical signs of vancomycin failure and describes the indications for and appropriate use of alternative antimicrobials such as ceftaroline, daptomycin, linezolid, tigecycline, and telavancin.

Charcoal reflectance reveals early Holocene boreal deciduous forests burned at high intensities

Published onlineJournal ArticleResearch Support, Non-U.S. Gov'tResearch Support, U.S. Gov't, Non-P.H.S.Wildfire size, frequency, and severity are increasing in the Alaskan boreal forest in response to climate warming. One of the potential impacts of this changing fire regime is the alteration of successional trajectories, from black spruce to mixed stands dominated by aspen, a vegetation composition not experienced since the early Holocene. Such changes in vegetation composition may consequently alter the intensity of fires, influencing fire feedbacks to the ecosystem. Paleorecords document past wildfire-vegetation dynamics and as such, are imperative for our understanding of how these ecosystems will respond to future climate warming. For the first time, we have used reflectance measurements of macroscopic charcoal particles (>180μm) from an Alaskan lake-sediment record to estimate ancient charring temperatures (termed pyrolysis intensity). We demonstrate that pyrolysis intensity increased markedly from an interval of birch tundra 11 ky ago (mean 1.52%Ro; 485°C), to the expansion of trees on the landscape ~10.5 ky ago, remaining high to the present (mean 3.54%Ro; 640°C) irrespective of stand composition. Despite differing flammabilities and adaptations to fire, the highest pyrolysis intensities derive from two intervals with distinct vegetation compositions. 1) the expansion of mixed aspen and spruce woodland at 10 cal. kyr BP, and 2) the establishment of black spruce, and the modern boreal forest at 4 cal. kyr BP. Based on our analysis, we infer that predicted expansion of deciduous trees into the boreal forest in the future could lead to high intensity, but low severity fires, potentially moderating future climate-fire feedbacks

Reactive oxygen species induce virus-independent MAVS-oligomerization in systemic lupus erythematosus

The increased expression of genes induced by type I interferon (IFN) is characteristic of viral infections and systemic lupus erythematosus (SLE). We showed that mitochondrial antiviral signaling (MAVS) protein, which normally forms a complex with retinoic acid gene I (RIG-I)–like helicases during viral infection, was activated by oxidative stress independently of RIG-I helicases. We found that chemically generated oxidative stress stimulated the formation of MAVS oligomers, which led to mitochondrial hyperpolarization and decreased adenosine triphosphate production and spare respiratory capacity, responses that were not observed in similarly treated cells lacking MAVS. Peripheral blood lymphocytes of SLE patients also showed spontaneous MAVS oligomerization that correlated with the increased secretion of type I IFN and mitochondrial oxidative stress. Furthermore, inhibition of mitochondrial reactive oxygen species (ROS) by the mitochondria-targeted antioxidant MitoQ prevented MAVS oligomerization and type I IFN production. ROS-dependent MAVS oligomerization and type I IFN production were reduced in cells expressing the MAVS-C79F variant, which occurs in 30% of sub-Saharan Africans and is linked with reduced type I IFN secretion and milder disease in SLE patients. Patients expressing the MAVS-C79F variant also had reduced amounts of oligomerized MAVS in their plasma compared to healthy controls. Together, our findings suggest that oxidative stress–induced MAVS oligomerization in SLE patients may contribute to the type I IFN signature that is characteristic of this syndrome

Generation of Laminar Vortex Rings by an Impulsive Body Force

It is shown that laminar vortex rings can be generated by impulsive body forces having particular spatial and temporal characteristics. The method produces vortex rings in a fluid initially at rest, and once generated, the flow field automatically satisfies the boundary conditions and is divergence-free. Numerical simulations and analytical models show that the strength of these rings can be accurately predicted by considering diffusion alone, despite the nonlinear nature of the generation process. A particularly simple model, which approximates the source of vorticity within vertical slabs, is proposed. This model predicts the ring circulation almost as accurately as a model which uses the exact geometry of the source of vorticity. It is found that when the duration of the force is less than a time scale based on the force radius and fluid viscosity, the ring circulation can be predicted accurately using an inviscid model.Comment: 37 pages, 11 figure

The Revised DACS Principles in Action: Applying Modern Practice to Legacy Description

Since SAA revised DACS\u27s archival description principles from 8 concepts into 11 reworked value statements in 2019, archivists have wondered how to incorporate the revised principles into existing description practices. Archivists from BYU and USU libraries have undertaken large projects on legacy collections informed by these principles. We invite attendees to learn from our experiences in implementing current DACS principles while grappling with less-than-ideal records. BYU will describe a project to revise the description of a significant collection of Mesoamerican materials after discovering the finding aid had serious problems introduced by previous revisions by archivists. USU will describe an undertaking to create over 2,500 University Archives collection descriptions from a shelf list and revising based on the new DACS principles. This joint session will demonstrate straightforward ways that two academic libraries have incorporated the DACS principles into archivists\u27 day-to-day work
