Who and why do researchers opt to publish in post-publication peer review platforms? - findings from a review and survey of F1000 Research
Authors: Kirkham Jamie , Moher David 
Published: June 2018

Background: Preprint servers and alternative publication platforms enable authors to accelerate the dissemination of their research. In recent years there has been an exponential increase in the use of such servers and platforms in the biomedical sciences, although little is known about who, why and what experiences researchers have with publishing on such platforms. In this article we explore one of these alternative publication platforms, F1000 Research, which offers immediate publication followed by post-publication peer review. Methods: From an unselected cohort of articles published between 13th July 2012 and 30th November 2017 in F1000 Research, we provided a summary of who and what was published on this platform and calculated the percentage of published articles that had been indexed on a bibliographic database (PubMed) following successful post-publication peer review. We also surveyed corresponding authors to further understand the rationale and experiences of those that have published using this platform. Results: A total of 1865 articles had been published in the study cohort period, of which 80% (n=1488) had successfully undergone peer review and were indexed on PubMed within a minimum period of six months since first publication. Nearly three-quarters of articles passed the peer review process with their initial submission. Survey responses were received from 296 corresponding authors. Open access, open peer review and the speed of publication were the three main reasons why authors opted to publish with F1000 Research. Conclusions: Many who published with F1000 Research had a positive experience and indicated that they would publish again with this same platform in the future. Nevertheless, there remained some concerns about the peer review process and the quality of the articles that were published.

Cryptococcal meningitis is a leading cause of morbidity and mortality among HIV-infected persons, accounting for 15% of AIDS-related deaths. Visual disturbance is commonly reported, and a wide range of ophthalmic signs may be present on examination. There is limited published literature to date describing the range and incidence of ophthalmic signs in HIV-associated cryptococcal meningitis. Nested within the Adjunctive Sertraline for the Treatment of HIV-Associated Cryptococcal Meningitis (ASTRO-CM) trial (ClinicalTrials.gov number: NCT01802385), we conducted an observational study of 696 Ugandan adults with HIV-associated cryptococcal meningitis. Patients were screened for visual disturbance and ophthalmic signs at initial presentation and at follow-up appointments over 18 weeks. Assessment comprised simple clinical history and basic examination and required no specialist equipment. More than a quarter of our cohort demonstrated ocular signs or symptoms, which were observed throughout the study period. A broad range of ocular signs were demonstrated: these included neurological signs (10.9%), localized ocular pathology (4.5%), and evidence of concurrent systemic disease (12.9%). The range of signs observed demonstrates the complexities of case management in patients with advanced HIV and cryptococcosis and also the importance of basic ocular examination in low resource settings. There remains an urgent need for studies conducting comprehensive ocular examination in patients with HIV-associated cryptococcal meningitis; these studies should include formal assessment of visual acuity, slit lamp examination and dilated indirect ophthalmoscopy. Prospective studies should investigate whether there is a correlation between reported visual disturbance and objective signs, in order to further clarify the underlying mechanisms and to guide effective diagnosis, follow-up and management.
Surface Detention on Cropland, Rangeland, and Conservation Reserve Program Areas
Authors: Gilley John .  E 
Published: June 2018

Abstract. One of the factors contributing to overland flow on upland areas is water stored temporarily in a thin sheet on the soil surface as surface detention. This study was conducted to quantify surface detention on selected cropland, rangeland, and Conservation Reserve Program (CRP) sites. Surface detention was determined from the recession portion of runoff hydrographs corresponding with the period when rainfall had ceased but runoff continued. The hydrographs were generated from six previously reported rainfall simulation studies conducted on paired 3.7 m wide × 10.7 m long plots on which approximately 128 mm of rainfall was applied. Surface detention values were found to increase as crop residue or vegetative cover increased. Eleven fallow cropland sites in the eastern U.S. had surface detention values that varied from 1.7 to 4.6 mm. Surface detention on plots in southwestern Oklahoma containing Old World bluestem, no-till wheat, and conservation-till wheat was 9.4, 7.3, and 5.2 mm, respectively. No-till sorghum, tilled sorghum, no-till wheat, and tilled wheat plots in southeast Nebraska had surface detention values of 6.7, 4.5, 6.7, and 4.6 mm, respectively. Mean surface detention on no-till and tilled cropland sites in southwest Iowa containing corn residue was 7.2 and 5.9 mm, respectively. CRP study sites in southwestern Iowa had mean surface detention of 10.8 mm. When data from the six field studies were combined, mean surface detention values for fallow cropland, tilled cropland, no-till cropland, rangeland, and CRP areas were 3.1, 5.0, 6.9, 9.6, and 10.8 mm, respectively.

An Improved Representation of Vegetative Filter Strips in SWAT

Published: June 2018

Abstract. Vegetative filter strips (VFS) are popular conservation practices installed at the edges of agricultural fields to reduce losses of pollutants from agricultural areas to receiving waterbodies. The recent interest in using VFS areas as multifunctional landscapes necessitates an improved depiction of VFS in simulation models. This study is aimed to enhance the physical representation of VFS in the Soil and Water Assessment Tool (SWAT) to improve the representation of ecohydrologic processes and land management practices in VFS areas. The proposed enhancement enables routing of water, sediment, and nutrients from the source area through the VFS area and makes the infiltrated water and nutrients available for filter crop uptake. The improvements are implemented in SWAT by modifying input files through Matlab scripts and by changing SWAT subroutines to enable routing. The model improvements are tested with three paired watershed studies with and without edge-of-field VFS in central Iowa. The improved model estimated 46% runoff reduction, 91% sediment reduction, 83% total phosphorus reduction, and 54% nitrate reduction with VFS, and these estimates closely matched the measured VFS reductions. The improved model was able to represent increased infiltration, soil moisture, and denitrification in the VFS area, along with accurately capturing crop yields in the source and VFS areas. Overall, the results indicate improved physical representation of VFS in SWAT. Keywords: Conservation measures, Flexible buffer strips, Multifunctional buffers, SWAT model, Vegetative filter strips.

Published: June 2018

Abstract. To mitigate noxious hydrogen sulfide (H2S) gas release that has been observed from gypsum-laden dairy manure, three additives were studied in sequential investigations. Three trials with specific aims were conducted using experimental vessels containing 15 kg of dairy manure each. Trial 1 investigated two additives: iron oxide (specifically, iron oxide-hydroxide, FeOOH) and a proprietary gypsum-lime based product (DriMatt). Trial 2 investigated effective ratios of gypsum to iron oxide and a modified DriMatt additive, and trial 3 evaluated iron oxide at the most effective ratio. Manure agitation events were monitored in the first two trials, while gas releases were continuously monitored in trial 3 during and between agitations. Hydrogen sulfide concentrations were captured using electrochemical sensors or a Fourier transfer infrared (FTIR) gas analyzer assembly over an incubation period of two months for the first two trials and over 40 days for the third trial. Additionally, nutrient analyses were performed for each trial. Extremely high concentrations of H2S were observed during most manure agitation events (500 to 8000 ppm), while minimum releases (&lt;10 ppm) were found when samples were static. Means of maximum concentrations of H2S were compared among treatments in each trial. Statistical tests showed that adding iron oxide to gypsum-laden manure reduced H2S production by an average of 94% compared to treatments without iron oxide. With a 1:1 molar ratio of iron oxide to gypsum, the level of H2S released was diminished to as low as the control manure (without gypsum). Therefore, iron oxide is a promising additive to mitigate H2S production in gypsum-laden dairy manure during agitation events.

Published: June 2018

Abstract. Stainless steel is one of the most widely used metals for food industry applications. Cavities and crevices on its surface are able to accommodate bacteria that can evade bactericidal activity. Therefore, the evaluation of electropolishing and anodizing treatments for anti-biofouling performance on stainless steel surfaces was carried out in this study. Plates of 316L stainless steel were electropolished to make nanosmooth surfaces in a mixture solution of phosphoric acid and sulfuric acid at 3.5 V at 80°C for 10 min. These samples were anodized in an anhydrous ethylene glycol solution containing perchloric acid to achieve nanoporous surfaces with diameters of 50 and 80 nm after being treated with 40 V for 10 min and 50 V for 35 min, respectively. Field emission scanning electron microscope and atomic force microscope images showed that the surface topographies of the stainless steel were strongly manipulated by the surface treatments. The populations of bacterial cells adhered to the nanosmooth, 50 nm nanoporous, and 80 nm nanoporous surfaces of stainless steel were 3.7, 1.7, and 1.5 log CFU cm-2, respectively. Nanoporous surfaces on stainless steel showed a significant repellency of as compared to nanosmooth stainless steel (p &lt; 0.05). The results suggest that nanoporous characteristics on stainless steel surface have a great potential for biofilm prevention in food industries.

Published: June 2018

Abstract. Change point analysis was used to explore the interactions between watershed characteristics and concentrations of nitrate-nitrogen, total nitrogen, soluble reactive phosphorus, and total phosphorus in streams within the Ozark Highlands, Arkansas Valley, and Ouachita Mountains ecoregions of Arkansas. Thresholds were identified for multiple watershed metrics used to predict water quality, including percent forest in the catchment, agricultural and forested land use in the riparian buffer, stream density, and poultry house density. Based on the observed relationships from the sampled watersheds, we propose four risk indicators to improve the identification of critical source areas for NPS pollution mitigation: subwatersheds that have less than 50% forested area within the drainage area, less than 50% forested area in the riparian buffer zone, more than 0.9 poultry houses km-2, and a stream density that exceeds 50 m ha-1. Keywords: Nonpoint-source pollution, Source water protection, Watershed management.
Laboratory Measurements of Evaporation Rate of Droplets at Low Relative Wind Speed
Authors: Teske Milton E. , Thistle Harold W. , Riley Christopher M. , Hewitt Andrew J. 
Published: June 2018

Abstract. This article summarizes further experimental data collected regarding the evaporation rate of isolated water droplets and strengthens previously published results regarding droplet evaporation at low relative wind speeds. The results suggest that as the Reynolds number (based on the relative velocity between the droplet and ambient air) decreases toward zero, the droplet evaporation rate falls to one-half its value. Because released spray droplets quickly attain near-background velocities, this result implies that evaporation continues for longer times than historically thought but at a lower rate. Additional measurements on traditional fluids (WHO, deionized, distilled, and tap water) provide a consistent benchmark with which to compare evaporation rates. Keywords: AGDISP, Droplets, Evaporation rate, Reynolds number.
How Do Temperature and Rainfall Affect Nitrous Oxide Emissions from Open-Lot Beef Cattle Feedyard Pens?

Published: June 2018

Abstract. Temperature is a primary factor affecting greenhouse gas (GHG) emissions from agricultural soils, but little is known about how temperature affects nitrous oxide (N2O) emissions from manure. The majority of grain-fed cattle in the Texas Panhandle are finished in large, earthen-surfaced, open-lot feedyards. Manure accumulates in feedyard pens and creates an environment high in nitrogen (N) and carbon (C) that can lead to N2O losses. In previous studies, N2O-N emissions from feedyard manure have been highly variable, ranging from negligible amounts from dry manure to 200 mg m-2 h-1 after a simulated rainfall event. The objective of this research was to determine how temperature affects N2O emissions from feedyard manure following rainfall. A recirculating flow-through, non-steady-state (RFT-NSS) chamber system with 1 m2 pans was used to monitor N2O emissions from beef cattle manure following a single 25.4 mm simulated rainfall event. Emissions were monitored at manure temperatures of 5.0°C, 11.2°C, 17.2°C, 21.5°C, 26.8°C, 31.0°C, 38.1°C, and 46.2°C. At all temperatures, a single N2O episode was observed following rainfall, peaking 2 to 11 h after rainfall with duration of 2 to 3 d. A second N2O episode was observed at temperatures =31.0°C, peaking 3 to 4 d after rainfall with duration of 18 d. When present, the second N2O episode accounted for 72% to 83% of the 20 d cumulative emissions. A step-increase in cumulative N2O emissions was observed between 26.8°C and 31.0°C, believed to be due to a major shift from denitrification to nitrification as the primary process of N2O production. Empirical regression models were developed for predicting cumulative N2O emissions based on temperature, which showed 88% agreement between predicted and field-observed N2O-N flux rates. These regression models will be useful for further quantification of N2O emissions from open-lot beef cattle feedyards in the U.S. Southern High Plains and for assessment of practices for reducing GHG emissions.

Published: June 2018

O artigo apresenta uma análise bibliométrica em que se identifica a incidência do uso e apropriações da triangulação como estratégia metodológica em Estudos de Caso publicados em periódicos científicos da área de Administração no Brasil. Entende-se a triangulação como uma estratégia importante para aumentar a compreensão em profundidade dos fenômenos estudados, bem como atribuir maior confiabilidade e fidedignidade aos Estudos de Caso e discutem-se cinco modalidades de triangulação: (i) triangulação de fontes de evidência, (ii) de métodos, (iii) de investigadores, (iv) teórica, e (v) a técnica de triangulação tal como proposta por Triviños (1987). A pesquisa analisou uma amostra de 1384 Estudos de Caso publicados entre os anos de 2008 e 2012 em periódicos da área classificados como A1 até B1 pela Coordenação de Aperfeiçoamento de Pessoal de Nível Superior – CAPES (conforme evento de qualificação Qualis 2013). Os resultados permitem concluir que a triangulação é pouco utilizada em Estudo de Caso na área de Administração nacional (é relatada em apenas 12% dos estudos analisados). Nos poucos casos em que é utilizada, os tipos de triangulação privilegiadas são as de fontes de evidência (100%) e as de método (86,72%), sendo raros estudos de caso que relatam a realização de triangulação teórica, de investigadores, ou técnicas de triangulação sistematizadas, como a proposta por Triviños (1987). Além da incidência e da apropriação que se faz da triangulação, foram identificados diversos equívocos no relato da utilização de triangulação. O texto explora esses mal-entendidos e apresenta sugestões para garantir o correto uso e relato da triangulação. Justifica-se a relevância do artigo dada a necessidade de refletir sobre a qualidade dos procedimentos metodológicos e dos relatos de pesquisa que se tem realizado na área de Administração.
Trends in the Educational Placement of Students With Intellectual Disability in the United States Over the Past 40 Years
Authors: Brock Matthew E. 
Published: June 2018

Abstract
In 1975, federal law mandated that children with disabilities be educated in their least restrictive environment, or alongside peers without disabilities in general education classrooms to the maximum extent appropriate. More than 40 years later, I investigated how national trends in educational placement have changed over time for students with intellectual disability. Specifically, I examined the degree placements have trended toward less restrictive environments. I found historical trends of incremental progress toward less restrictive settings, but no evidence of such progress in recent years. Furthermore, most students were educated predominantly in segregated settings every year. I discuss how these findings relate to previous studies, as well as implications for individualized education program teams and advocates for educational inclusion.

Abstract
This project sought to identify Medicaid members with intellectual and developmental disabilities (IDD) in five states (Delaware, Iowa, Massachusetts, New York, and South Carolina) to develop a cohort for subsequent analyses of medical conditions and service utilization. We estimated that over 300,000 Medicaid members in these states had IDD. All members with diagnostic codes for IDD were identified and the three most frequent diagnoses were unspecified intellectual disability, autism or pervasive developmental disorder, and cerebral palsy. The percentage of Medicaid members with IDD ranged from 2.3% in New York to 4.2% in South Carolina. Identifying and characterizing people with IDD is a first step that could guide public health promotion efforts for this population.
Elastic Constants and Related Properties of Compressed Rocksalt CuX (X =Cl, Br): Ab Initio Study
Authors: Bioud Nadhira , Sun Xiao-Wei , Bouarissa Nadir , Daoud Salah 
Published: June 2018

Abstract
First-principles calculations are performed to study the structural and elastic properties, sound velocities, and Debye temperature of rocksalt-structured copper monochloride (CuCl) and copper monobromide (CuBr). The structural parameters, elastic constants, longitudinal, transverse, and average elastic wave velocities, and the Debye temperature in the pressure range 10–20 GPa are successfully predicted and analysed. The variation of the elastic constants and bulk modulus as a function of pressure is found to be non-linear for CuCl and almost linear for CuBr. Based on the obtained values of the elastic constants, the bulk modulus, the isotropic shear modulus, Young’s modulus, Poisson’s ratio, and Pugh’s ratio of the aggregate materials are also investigated. The analysis of Poisson’s and Pugh’s ratios shows that these materials become ductile for pressures in the range 10–20 GPa. The evolution of the longitudinal sound velocity under pressure indicates the hardening of the corresponding phonons in both materials.
Dauerhafte Wohnraumversorgung wohnungsloser Menschen – Eine Ersterhebung eines neuen Organisationstypus
Authors: Steffen Axel 
Published: June 2018

Abstract
Der vorliegende Artikel basiert auf einer erstmaligen Erhebung von Organisationen in Deutschland, die Wohnraum akquirieren und verwalten und ihn an wohnungslose Menschen bzw. Wohnungsnotfälle vermieten, die anderweitig keinen Zugang zu eigenem, mietvertraglich abgesichertem Wohnraum finden. Da in der wissenschaftlichen Literatur bisher keine erprobten Instrumente für die fallübergreifende Erhebung solcher Organisationen bekannt sind, wurde ein eigenes Kategoriensystem entwickelt. Unter Verwendung einer Dokumentenanalyse und von Experteninterviews wurden insgesamt sieben Soziale Wohnraumagenturen in Deutschland analysiert und miteinander verglichen. Zwar bleibt der quantitative Erfolg bei der Wohnungsversorgung angesichts der um ein Vielfaches höheren Wohnungslosenzahlen begrenzt, gleichwohl deuten die Befunde darauf hin, dass diese Organisationen sehr erfolgreich bei der (Re-)Integration von Menschen mit besonderen sozialen Schwierigkeiten in Wohnraum und der Sicherung von Wohnraum sind. Anders als für vergleichbare Organisationen im europäischen Ausland (z. B. Belgien) gibt es für Soziale Wohnraumagenturen in Deutschland jedoch keine einheitliche, dauerhaft gesicherte Finanzierungsgrundlage.
