Increasing Collaborative Communication Regarding Proper Positioning: A Photographic Guide

Approximately 98,000 people die annually in the United States due to medical errors (Institute of medicine, 2013). These medical errors are most often due to miscommunication between healthcare providers (Sutcliffe, Lewton, & Rosenthal, 2004). Impaired positioning is one type of medical error, which leads to severe complications such as contractures, pressure ulcers, and occupational deficits (Amidei, 2012; de Jong, Nieuwboer, & Aufdemkampe, 2006; Gordon, Gottschlich, Helvig, Marvin, & Richard, 2004). The purpose of this scholarly project is to provide a communication tool that will increase interprofessional communication and collaboration in regards to client positioning needs in healthcare settings. A literature review was conducted on positioning guidelines, communication strategies and barriers, and teaching strategies. The five target diagnoses of this scholarly project were traumatic brain injury (TBI), cerebral vascular accident (CVA), spinal cord injury, burn, and orthopedic injury. The goal of this program is to decrease secondary complications related to improper positioning that will impede occupational performance by providing consistent and evidence-based positioning strategies. The Model of Human Occupation (MOHO), Social Learning Theory, and Dynamical Systems Theory were utilized to guide the creation of this scholarly project. The resulting product was an adaptable interdisciplinary communication tool to guide positioning of clients with the aforementioned diagnoses as well as other individuals with limited mobility. Through implementation of this communication tool, clinicians can provide consistent and evidence-based positioning to their clients, increase interdisciplinary communication and carryover of care, and assist in prevention of secondary medical complications related to improper positioning

Special Issue Foreword: On the Political Economy of Amateur Athletics

In its most artless definition, political economy refers to the study of inter- and intrastate transaction—concerned in large part with the dialectics of state governance and the production/consumption functions therein. Many of us, with varying degrees of deliberation, have read the works of forerunning political economists such as Adam Smith (c. 1723-1790), David Ricardo (c. 1772-1823), Thomas Malthus (c. 1766-1834), John Stuart Mill (c. 1806-1873), Karl Marx (c. 1818-1883), and Thorstein Veblen (c. 1857-1929). These classic political economists and their contemporaries shared a concern for the extent to which land, labor, income, capital, and the population derived value from, and maintained contingency with, state polity. While each diverged from the others in how to best organize the State in relation to markets and exchange activities (and vice versa) so as to optimize the citizenry’s well-being, these scholars and their contemporaries laid the foundations for the long-standing field of inquiry fixed on exploring how various national political systems (democracy, monarchy, aristocracy, oligarchy, etc.), markets, and political and economic behavior could bring about national prosperity, maximize individual freedom, or raise collective utility

Framing democracy: Stadium financing and civic paternalism in Test Market, USA

The vast majority of North America’s professional sport arenas, ballparks, and stadiums are publicly subsidized without direct approval from voters. In this article, we examine the discursive constitution of ‘no-vote subsidies’ within the public sphere, and in particular problematize the twinned production(s) of citizenship and democratic process in framing public subsidization of these sites of private accumulation. To do this, we examine the recent no-vote subsidy occurring in Columbus, Ohio—thereby providing context-specific interrogation of the mediations of participatory citizenship, political decision-making, and the institution of democracy as related to sport stadium funding. As part of this analysis, we discuss the public production of civic paternalism—a political ideology focused on urban growth and unconcerned with future electoral consequences—in the Columbus arena financing case. We conclude the article with a call for increasing scholarly engagement in, and intervention into, the political processes that result in the public subsidization of professional sport venues

Public Parks Usage Near Hydraulic Fracturing Operations

Following the advent of hydraulic fracturing to effectively collect natural gas and oil, there has been growing interest in placing exploration and extraction wells in or adjacent to public park and forest systems across North America and Europe. At the heart of the debate about leasing public parkland is the concern that park acreage and accessibility will be lost to fracking operations, thereby decreasing park attendance. In this study, we apply value-belief-norm theory to evaluate park users’ general attitudes toward fracking and public policy and their perceptions of fracking’s impact on their recreational activity. A survey of 255 park users in the Appalachian Basin of the United States indicated that individuals holding strong pro-environmental attitudes in general would likely avoid parklands that are affected by fracking operations. Additionally, a majority of respondents reported concern that fracking would disrupt park access and thusly supported legislative bans of fracking in public parklands

High-Order Stabilized Finite Elements on Dynamic Meshes

The development of dynamic mesh capability for turbulent flow simulations using the Streamlined Upwind Petrov-Galerkin (SUPG) discretization is described. The current work extends previous research to include high-order spatial accuracy, including the satisfaction of the discrete geometric conservation law (GCL) on curved elements. Two closely-related schemes are described and the ability of these schemes to satisfy the GCL, while also maintaining temporal accuracy and conservation is assessed. Studies indicate that although one scheme discretizes the time derivative in conservative form, both schemes exhibit temporal conservation errors that decrease according to the expected design order of accuracy. The source of the temporal conservation errors is examined, and it is demonstrated that many finite-volume and finite-element schemes can also be expected to have difficulty strictly satisfying conservation in time. The effects on conservation are examined and, while present in the simulations, are seen to be negligible for the problems considered

Color and pigment polymorphisms of northern leopard frogs on a prairie landscape

Variation allows populations to adapt to changing conditions. As human activities continue to alter environments and evolutionary processes, it becomes increasingly important to conserve standing genetic variation. Despite technical advances in population genetics, it is still useful to have inexpensive methods of detecting and monitoring genetic variation, particularly in traits that potentially influence fitness. In the Northern Leopard Frog, Lithobates pipiens (= Rana pipiens), genetically determined color (green [dominant: G] or brown [recessive: g]) and two pigment pattern polymorphisms (Burnsi/spotless [B] or spotted [b]; Kandiyohi/mottled [K] or non-mottled[k]) are hypothesized to have adaptive benefits. We assessed spatiotemporal patterns of these polymorphisms during two time periods in one of the largest remaining grasslands in North America. The frequency of the dominant green phenotype remained consistent from the early-to-late 2000s; however, we observed Kandiyohi phenotypes more frequently during 2001–2002 compared to 2009–2010. By contrast, we observed dominant Burnsi phenotypes more frequently in the latter time period. Although not statistically significant, we observed green phenotypes more frequently in areas with less water on the landscape and in locations closer to tree cover. Burnsi phenotypes were more common in wetlands that did not dry out and Kandiyohi phenotypes were more common in wetlands with aquatic vegetation, although not significantly. No pigment polymorphism was associated with body size. We found no indication of spatial structure, suggesting ample gene flow. The correlations were generally weak, but some were consistent with hypotheses of adaptive benefits. This genetically determined phenotypic variation could be important under changing climactic conditions or if land uses change

Stabilized Finite Elements in FUN3D

A Streamlined Upwind Petrov-Galerkin (SUPG) stabilized finite-element discretization has been implemented as a library into the FUN3D unstructured-grid flow solver. Motivation for the selection of this methodology is given, details of the implementation are provided, and the discretization for the interior scheme is verified for linear and quadratic elements by using the method of manufactured solutions. A methodology is also described for capturing shocks, and simulation results are compared to the finite-volume formulation that is currently the primary method employed for routine engineering applications. The finite-element methodology is demonstrated to be more accurate than the finite-volume technology, particularly on tetrahedral meshes where the solutions obtained using the finite-volume scheme can suffer from adverse effects caused by bias in the grid. Although no effort has been made to date to optimize computational efficiency, the finite-element scheme is competitive with the finite-volume scheme in terms of computer time to reach convergence

Enzymatic degradation of phenazines can generate energy and protect sensitive organisms from toxicity

Diverse bacteria, including several Pseudomonas species, produce a class of redox-active metabolites called phenazines that impact different cell types in nature and disease. Phenazines can affect microbial communities in both positive and negative ways, where their presence is correlated with decreased species richness and diversity. However, little is known about how the concentration of phenazines is modulated in situ and what this may mean for the fitness of members of the community. Through culturing of phenazine-degrading mycobacteria, genome sequencing, comparative genomics, and molecular analysis, we identified several conserved genes that are important for the degradation of three Pseudomonas-derived phenazines: phenazine-1-carboxylic acid (PCA), phenazine-1-carboxamide (PCN), and pyocyanin (PYO). PCA can be used as the sole carbon source for growth by these organisms. Deletion of several genes in Mycobacterium fortuitum abolishes the degradation phenotype, and expression of two genes in a heterologous host confers the ability to degrade PCN and PYO. In cocultures with phenazine producers, phenazine degraders alter the abundance of different phenazine types. Not only does degradation support mycobacterial catabolism, but also it provides protection to bacteria that would otherwise be inhibited by the toxicity of PYO. Collectively, these results serve as a reminder that microbial metabolites can be actively modified and degraded and that these turnover processes must be considered when the fate and impact of such compounds in any environment are being assessed
