Implementation of Slant-Path Radiative Transfer in Environment Canada’s Global Deterministic Weather Prediction System
Authors: Shahabadi Maziar Bani , Buehner Mark , Aparicio Josep , Garand Louis 
Published: August 2020

AbstractThe standard approach for assimilating satellite radiance observations is to interpolate all vertical levels of the background state and analysis increment to the same horizontal location for input to the radiative transfer model. This can add significant error for observations with large zenith angle. The impact of accounting for the true slanted satellite-viewing geometry was tested by modifying the horizontal interpolation routines in Environment and Climate Change Canada’s Global Deterministic Weather Prediction System. Consequently, model variables are interpolated to a different horizontal position at each model level, for either just the innovation or both the innovation and increment calculation. When this slant-path operator is used for simulation of radiances, reductions in innovation standard deviation, up to 4.5%, for upper-tropospheric and stratospheric temperature and humidity channels of ATMS, AMSU-A, MHS, and CrIS instruments have similar magnitudes as reported in previous studies. In data assimilation experiments, statistically significant reductions in innovation standard deviation (up to 0.3%) for global GPSRO observations are obtained, due to an improved background state. Verification of short- and medium-range forecasts against ERA5, and our own analyses over the region poleward of 60°S show statistically significant reductions of error standard deviation by 2%–3% for wind and temperature in the upper troposphere and lower stratosphere. These positive impacts are mostly due to performing slant-path interpolation on the background state, while also using slant path on the analysis increment has little additional impact. This is expected since the analysis increment in this global configuration has lower spatial resolution, with grid spacing comparable with the maximum horizontal position error from not using the slant-path operator.
The Mechanisms Responsible for Large Near-Surface Vertical Vorticity within Simulated Supercells and Quasi-Linear Storms
Authors: Boyer Christian H. , Dahl Johannes M. L. 
Published: August 2020

AbstractDespite their structural differences, supercells and quasi-linear convective systems (QLCS) are both capable of producing severe weather, including tornadoes. Previous research has highlighted multiple potential mechanisms by which horizontal vorticity may be reoriented into the vertical at low levels, but it is not clear in which situation what mechanism dominates. In this study, we use the CM1 model to simulate three different storm modes, each of which developed relatively large near-surface vertical vorticity. Using forward-integrated parcel trajectories, we analyze vorticity budgets and demonstrate that there seems to be a common mechanism for maintaining the near-surface vortices across storm structures. The parcels do not acquire vertical vorticity until they reach the base of the vortices. The vertical vorticity results from vigorous upward tilting of horizontal vorticity and simultaneous vertical stretching. While the parcels analyzed in our simulations do have a history of descent, they do not acquire appreciable vertical vorticity during their descent. Rather, during the analysis period relatively large horizontal vorticity develops as a result of horizontal stretching, and therefore this vorticity can be effectively tilted into the vertical.
A New Methodology for Observation-Based Parameterization Development

Published: August 2020

AbstractWe develop a methodology for identification of candidate observables that best constrain the parameterization of physical processes in numerical models. This methodology consists of three steps: (i) identifying processes that significantly impact model results, (ii) identifying observables that best constrain the influential processes, and (iii) investigating the sensitivity of the model results to the measurement error and vertical resolution of the constraining observables. This new methodology is applied to the Jet Propulsion Laboratory stochastic multiplume Eddy-Diffusivity/Mass-Flux (JPL-EDMF) model for two case studies representing nonprecipitating marine stratocumulus and marine shallow convection. The uncertainty of physical processes is characterized with uncertainty of model parameters. We find that the most uncertain processes in the JPL-EDMF model are related to the representation of lateral entrainment for convective plumes and parameterization of mixing length scale for the eddy-diffusivity part of the model. The results show a strong interaction between these uncertain processes. Measurements of the water vapor profile for shallow convection and of the cloud fraction profile for the stratocumulus case are among those measurements that best constrain the uncertain JPL-EDMF processes. The interdependence of the required vertical resolution and error characteristics of the observational system are shown. If the observations are associated with larger error, their vertical resolution has to be finer and vice versa. We suggest that the methodology and results presented here provide an objective basis for defining requirements for future observing systems such as future satellite missions to observe clouds and the planetary boundary layer.
Modes of Storm-Scale Variability and Tornado Potential in VORTEX2 Near- and Far-Field Tornadic Environments

Published: August 2020

AbstractSome supercellular tornado outbreaks are composed almost entirely of tornadic supercells, while most consist of both tornadic and nontornadic supercells sometimes in close proximity to each other. These differences are related to a balance between larger-scale environmental influences on storm development as well as more chaotic, internal evolution. For example, some environments may be potent enough to support tornadic supercells even if less predictable intrastorm characteristics are suboptimal for tornadogenesis, while less potent environments are supportive of tornadic supercells given optimal intrastorm characteristics. This study addresses the sensitivity of tornadogenesis to both environmental characteristics and storm-scale features using a cloud modeling approach. Two high-resolution ensembles of simulated supercells are produced in the near- and far-field environments observed in the inflow of tornadic supercells during the second Verification of the Origins of Rotation in Tornadoes Experiment (VORTEX2). All simulated supercells evolving in the near-field environment produce a tornado, and 33% of supercells evolving in the far-field environment produce a tornado. Composite differences between the two ensembles are shown to address storm-scale characteristics and processes impacting the volatility of tornadogenesis. Storm-scale variability in the ensembles is illustrated using empirical orthogonal function analysis, revealing storm-generated boundaries that may be linked to the volatility of tornadogenesis. Updrafts in the near-field ensemble are markedly stronger than those in the far-field ensemble during the time period in which the ensembles most differ in terms of tornado production. These results suggest that storm-environment modifications can influence the volatility of supercellular tornadogenesis.

Published: August 2020

AbstractMany rural communities in the western United States are surrounded by public lands and are dependent on these landscapes for their livelihoods. Climate change threatens to affect land-based livelihoods through both direct impacts and public land agency decision-making in response to impacts. This project was designed to understand how Bureau of Land Management (BLM) permittees, including ranching and recreation-based businesses in Colorado, are vulnerable to both climate change and management responses and how permittees and the BLM are adapting and could adapt to these changes. We conducted 60 interviews in two BLM field offices to gather permittee and agency employees’ observations of change, impacts, responses, and suggestions for adaptive actions. Data suggested that permittees are dependent on BLM lands and are sensitive to ecological and management changes and that current management policies and structures are often a constraint to adaptation. Managers and permittees are already seeing synergistic impacts, and the BLM has capacity to facilitate or constrain adaptation actions. Participants suggested increased flexibility at all scales, timelier within-season adjustments, and extension of current collaborative efforts to assist adaptation efforts and reduce impacts to these livelihoods.
Challenges Facing Latin American Peasant Movements under Progressive Governments and New Right-Wing Parties: The Case of Brazil
Authors: Barbosa Lia Pinheiro 
Published: August 2020

This article analyzes the dilemmas faced by peasant movements in Brazil during the “progressive governments” and the return of the right to power. To this end, it analyzes the case of the Landless Rural Workers Movement (MST) in two scenarios of recent political history. The first is that of the progressive governments, characterized by a simultaneous opening of public space and public policies to popular movements, although at the same time and contradictorily, also to the private sector linked to financial and transnational capital. The second scenario is that of the rise of the far right to power, first through a parliamentary coup d’état, and then by an electoral process. O artigo analisa os dilemas enfrentados pelos movimentos camponeses no Brasil durante os “governos progressistas” e no retorno das direitas ao poder. Para tanto, se analisa o caso do Movimento dos Trabalhadores Rurais Sem Terra (MST) em dois cenários da história política recente: o primeiro, no marco dos governos progressistas, caracterizado por uma abertura do espaço público, no campo das políticas públicas, aos movimentos populares, ainda que ao mesmo tempo e de maneira contraditória, também ao setor privado vinculado ao capital financeiro e transnacional. O segundo cenário é o da ascensão, mediante um golpe de Estado parlamentário, seguido de processo eleitoral, da direita ao poder.

Objective This study was performed to evaluate the proximal anatomical compatibility of stems for treatment of Crowe IV developmental dysplasia of the hip (DDH) using a previously developed three-dimensional comparison technique. Methods Patients with Crowe IV DDH who underwent computed tomography were retrospectively analyzed. The femoral medullary canals were three-dimensionally reconstructed, and models of cementless modular (S-ROM; DePuy Synthes) and conical (Wagner Cone; Zimmer Biomet) implants were used for virtual implantation. The negative point percentages (NPPs) were applied to verify fitting. The average distance (deviation) and the root mean square of the distance (RMSd) were used to quantify geometric compatibilities. Results Four (16.7%) and 12 (50.0%) femoral medullary canals could not be fitted properly with either the modular or conical implant. The NPPs in the distal comparison region were significantly greater in the conical than modular group. The deviation was significantly smaller in the modular than conical group. The RMSd was also significantly smaller in the modular than conical group. Conclusions Compared with conical implants, modular implants might be more effectively used in patients with Crowe type IV DDH. However, some Crowe IV DDH femurs with severe deformity cannot be fitted with either of these two on-shelf implants.
Occupational therapy practice with children with developmental coordination disorder: An online qualitative vignette survey
Authors: O’Dea Áine Emma , Coote Susan , Robinson Katie 
Published: August 2020

Introduction Children and young people with developmental coordination disorder experience multiple occupational performance and participation challenges across environments. Research to date has not fully explored occupational therapy practice with children with developmental coordination disorder and their families. This study aims to describe current occupational therapy practice with children with developmental coordination disorder. Method This study used a cross-sectional, online qualitative vignette survey methodology. International occupational therapists who were working with or had worked with children with developmental coordination disorder within the previous 5 years were invited to participate. Following a case vignette, clinicians were asked questions prompting them to describe their practice based upon the vignette. The data were analysed thematically. The Consolidated Criteria for Reporting Qualitative Research and Checklist for Reporting Results of Internet E-Surveys reporting guidelines were adhered to. Findings Fifty-three valid responses were analysed. Analysis identified three themes describing occupational therapy practice with children with developmental coordination disorder: (a) a collaborative approach to establish occupation-focused goals; (b) occupation-focused assessment to guide therapy and diagnose developmental coordination disorder; and (c) the use of occupation-based interventions incorporating multiple strategies to enhance occupational engagement. Conclusion This study suggests that current occupational therapy practice with children with developmental coordination disorder is collaborative, occupation-focused, and multi-component. Findings highlight a gap between the complexity of practice and the nature of interventions evaluated in research to date.

Published: August 2020

Purpose: To examine the reliability and validity of a brief measure (the Workplace Support for Health [WSH] scale) to assess employees’ perceived support for a healthy lifestyle. Design: Repeated cross-sectional surveys. Setting: We collected employer- and employee-level survey data from small, low-wage workplaces in King County, WA enrolled in a randomized controlled trial. Sample: We analyzed data from 68 workplaces that had 2,820 and 2,640 employees complete surveys at baseline and 15 months, respectively. Measures: The WSH scale consisted of five items. To assess validity, we examined associations between the WSH scale and employer implementation of evidence-based interventions for health promotion, employee self-rated health, and job satisfaction. Analysis: We performed an exploratory factor analysis to assess the unidimensionality of the WSH scale items, and produced Cronbach’s alpha coefficients to examine scale reliability. We ran regression models using generalized estimating equations to examine validity. Results: The factor analysis indicated one factor, which accounted for 59% of the total variance in the workplace support for health items. The scale had good reliability at baseline (α = 0.82) and 15 months (α = 0.83). Employer evidence-based intervention implementation was positively associated with WSH. WSH was also associated with higher self-rated health and job satisfaction. These associations indicate good concurrent validity. Conclusion: The WSH scale is a reliable and valid measure of perceived workplace support for health. Employers can use the scale to identify gaps in support and create a plan for improvement.

Introduction Antiphospholipid antibodies (aPL) have been associated with organ damage and certain features in systemic lupus erythematosus(SLE) patients. Our aim was to investigate the differences between SLE patients according to the presence of aPL and/or clinical antiphospholipid syndrome (APS). Materials and methods Patients from the RELESSER-T registry were included. RELESSER-T is a Spanish multicenter, hospital-based, retrospective, SLE registry. Results We included 2398 SLE patients, 1372 of whom were positive for aPL. Overall 1026 patients were classified as SLE, 555 as SLE-APS and817 as SLE-aPL. Regarding cardiovascular risk factors, SLE-APS patients had higher rates of hypertension, dyslipidemia and diabetes than those with SLE-aPL and SLE ( p < 0.001). SLE-APS patients showed higher rates of neuropsychiatric, cardiac, pulmonary, renal and ophthalmological manifestations than the other groups ( p < 0.001). SLE-APS patients presented greater damage accrual with higher SLICC values (1.9 ± 2.2 in SLE-APS, 0.9 ± 1.4 in SLE-aPL and 1.1 ± 1.6 in SLE, p < 0.001) and more severe disease as defined by the Katz index (3 ± 1.8 in SLE-APS, 2.7 ± 1.7 in SLE-aPL and 2.6 ± 1.6 in SLE, p  < 0.001). SLE-APS patients showed higher mortality rates ( p < 0.001). Conclusions SLE-APS patients exhibited more severe clinical profiles with higher frequencies of major organ involvement, greater damage accrual and higher mortality than SLE-aPL and SLE patients.

Objective: The virtual cone beam computed tomography–derived 3-dimensional model was compared with the scanned conventional model used in the fabrication of a palatal obturator for a patient with a large palatal defect. Design: A digitally derived 3-dimensional maxillary model incorporating the palatal defect was generated from the patient’s existing cone beam computerized tomography data and compared with the scanned cast from the conventional impression for linear dimensions, area, and volume. The digitally derived cast was 3-dimensionally printed and the obturator fabricated using traditional techniques. Similarly, an obturator was fabricated from the conventional cast and the fit of both final obturator bulbs were compared in vivo. Results: The digitally derived model produced more accurate volumes and surface areas within the defect. The defect margins and peripheries were overestimated which was reflected clinically. Conclusion: The digitally derived model provided advantages in the fabrication of the palatal obturator; however, further clinical research is required to refine consistency.

Published: August 2020

Objectives The purpose of this study was to evaluate the feasibility and short-term impact of a brief opioid overdose prevention and mitigation training administered to detained youth at risk for witnessing an overdose. Methods Adolescents seen in the medical clinic in a youth detention center were screened to determine risk for witnessing an overdose. Eligible adolescents completed a pretraining assessment that included opioid witnessing experiences and knowledge of and attitudes toward opioid overdose prevention. Participants completed a one-on-one overdose first aid training, received a naloxone (Narcan) kit at release, and completed a posttraining assessment of knowledge and attitudes. At 1 month and 3 months postrelease, participants completed telephone interviews to report satisfaction and application of training concepts. Results A total of 39 adolescent residents participated in this pilot study. Rates of recruitment and retention, as well as high rates of witnessing opioid use and overdose, indicate that opioid overdose prevention interventions are warranted with this population. There were significant changes in knowledge, confidence, and readiness to intervene in an opioid overdose from pre- to posttraining. At follow-up, the majority of participants still possessed their naloxone, and all reported sharing information from the training with others and having a plan if they witnessed an overdose. One participant reported completion of an overdose reversal. Implications Opioid overdose prevention training with detained youth is feasible and shows promising impacts on knowledge and application, meriting the need for future research.

Published: August 2020

Background Low-frequency repetitive transcranial magnetic stimulation (rTMS) over the contralesional motor cortex (M1) has demonstrated beneficial effects on motor recovery, but evidence among patients with subacute stroke is lacking. We aimed to investigate whether 1-Hz rTMS over the contralesional M1 versus sham rTMS could improve arm function in patients with subacute ischemic stroke when combined with rehabilitative motor training. Methods In total, 77 patients who were within 90 days after their first-ever ischemic stroke were enrolled and randomly allocated to either real (n = 40) or sham rTMS (n = 37). We delivered 1-Hz 30-minute active or sham rTMS before each daily 30-minute occupational therapy sessions over a 2-week period. The primary endpoint was changes in the Box and Block Test (BBT) score immediately after the end of treatment (EOT). Secondary analyses assessed changes in Fugl-Meyer assessment, Finger Tapping Test (FTT), Brunnstrom stage, and grip strength. Clinical Trial Registration ClinialTrials.gov (NCT02082015). Results Changes in BBT immediately after the end of treatment did not differ significantly between the 2 groups ( P = .267). Subgroup analysis according to cortical involvement revealed that real rTMS resulted in improvements in BBT at 1 month after EOT (17.4 ± 9.8 real vs 10.9 ± 10.3 sham; P = .023) and Brunnstrom stage of the hand immediately after EOT (0.6 ± 0.5 real vs 0.2 ± 0.5 sham; P = .023), only in the group without cortical involvement. Conclusion The effects of real and sham rTMS did not differ significantly among patients within 3 months poststroke. The location of stroke lesions should be considered for future clinical trials.
