Mediating Effect of Challenges on Demographics and Coping Strategies of Indian Healthcare Workers during COVID-19

Healthcare workers (HCWs) including doctors, nurses and allied workers struggled to cope up with the stressful situation as the COVID-19 pandemic unsettled healthcare systems, including India’s. Many factors (commonly called as stressors) acted as major sources of stress and resulted in poor mental health of HCWs. Therefore, this study predicted and explained the mediating effect of challenges on demographic characteristics and coping strategies of HCWs. Data from a cross-sectional study was collected from the district hospital of Rajasthan, India, during the period of August 2022–October 2022. HCW’s experience level, shift type and distance of greenspaces from their accommodation were significantly correlated with the challenges they faced at work, specifically societal challenges. Thus, HCWs were more inclined to adopt a meaning-focused coping strategy to retain good mental health during the pandemic. Therefore, these findings call for interventions requiring a layered response, comprising strategies and actions that are structural. At the organizational level, these actions may provide supportive workplace environments.
Impact of perceived supervisor support and leader-member exchange on employees’ intention to leave in public sector museums: A parallel mediation approach

High staff turnover in certain public sector organizations in Pakistan is a challenging problem, and organizations strive to reduce this issue using different mechanisms. Therefore, this research investigates the parallel mediation impact of perceived organizational support (POS) and organizational citizenship behavior (OCB) on the relationships among perceived supervisor support (PSS), leader-member exchange (LMX), and employee’s intention to leave (IL). Data were collected from 482 employees working in public sector museums in Pakistan in three waves. Structural equation modeling (SEM) with a two-step approach was used to evaluate the data. The research found that both POS and OCB mediate the negative relationship between PSS and IL and between LMX and IL in a parallel mediation mechanism. Public sector museums should focus on providing visible supervisory support and develop a healthy work environment where the exchange relationship between supervisors and subordinates strengthens to reduce the possibility of the employee’s leave intentions.
A practical second-order electromagnetic model in the quasi-specular regime based on the curvature of a ‘good-conducting’ scattering surface

Abstract This letter presents an approximate second-order electromagnetic model where polarization coefficients are surface dependent up to the curvature order in the quasi-specular regime. The scattering surface is considered ‘good-conducting’ as opposed to the case for our previous derivation where perfect conductivity was assumed. The model reproduces dynamically, depending on the properties of the scattering surface, the tangent-plane (Kirchhoff) or the first-order small-perturbation (Bragg) limits. The convergence is assumed to be ensured by the surface curvature alone. This second-order model is shown to be consistent with the small-slope approximation of Voronovich (SSA-1+SSA-2) for perfectly conducting surfaces. Our model differs from SSA-1 + SSA-2 in its dielectric expression, to correct for a full convergence toward the tangent-plane limit under the ‘good-conducting’ approximation. This new second-order formulation is simple because it involves a single integral over the scattering surface and therefore it is suitable for a vast array of analytical and numerical applications in quasi-specular applications.
Environmental Flow Impacts on Tropical Cyclone Structure Diagnosed from Airborne Doppler Radar Composites

AbstractFollowing a recent demonstration of multicase compositing of axisymmetric tropical cyclone (TC) structure derived from airborne Doppler radar measurements, the authors extend the analysis to the asymmetric structure using an unprecedented database from 75 TC flights. In particular, they examine the precipitation and kinematic asymmetry forced by the TC's motion and interaction with vertical wind shear. For the first time they quantify the average magnitude and phase of the three-dimensional shear-relative kinematic asymmetry of observed TCs through a composite approach. The composite analysis confirms principal features of the shear-relative TC asymmetry documented in prior numerical and observational studies (e.g., downshear tilt, downshear-right convective initiation, and a downshear-left precipitation maximum). The statistical significance of the composite shear-relative structure is demonstrated through a stratification of cases by shear magnitude. The impact of storm motion on eyewall convect.
Multi-mode models of flow and of solute dispersion in shallow water. Part 3. Horizontal dispersion tensor for velocity

Svendsen & Putrevu (1994) revealed that the much larger off-shore than vertical effective viscosity for longshore currents is the consequence of a shear dispersion mechanism. The multi-mode representation for the flow gives a mathematical framework within which a more general derivation can be made. It is shown that to a first approximation the horizontal shear dispersion tensor for velocity is the same as that for solutes.
Spectral Characteristics of the Baroclinic Annulus Waves

Abstract This paper reports the results of a statistical study of the temperature field of several examples of regular wave, vacillating flow and irregular flow in a rotating annulus with a gap width of 10 cm using a limited number of thermocouples. The primary results indicate that the regular waves produce several wavenumber harmonies through nonlinear interactions. The wavenumber harmonies decrease in the vacillating flow and are not detectable in the irregular flow. Further, the azimuthal coherence of the flow in the irregular regime decreases very rapidly in azimuth, and yet the vertical coherence is extremely high at all frequencies indicating a strong two-dimensional character of the irregular regime.
Multiple Imputation with Diagnostics (mi) in R: Opening Windows into the Black Box

Our mi package in R has several features that allow the user to get inside the imputation process and evaluate the reasonableness of the resulting models and imputations. These features include: choice of predictors, models, and transformations for chained imputation models; standard and binned residual plots for checking the fit of the conditional distributions used for imputation; and plots for comparing the distributions of observed and imputed data. In addition, we use Bayesian models and weakly informative prior distributions to construct more stable estimates of imputation models. Our goal is to have a demonstration package that (a) avoids many of the practical problems that arise with existing multivariate imputation programs, and (b) demonstrates state-of-the-art diagnostics that can be applied more generally and can be incorporated into the software of others.
A case study of alcohol use among male university rugby players

ABSTRACT In the UK, research has established that student athletes consume greater quantities of alcohol than their non-athlete peers. The published literature suggests the drinking culture in sport is a social phenomenon. At present, however, the evidence does not tell us what the precise mechanisms involved in the production and reproduction of the drinking culture are. To gain a deeper understanding of these mechanisms a case study methodology was used, where a researcher was heavily immersed within a male university rugby environment for a season. Data sources included observation, field-note taking, documentation, conversational interviews, and formal semi-structured interviews. These athletes faced a multitude of pressures encouraging them to drink, and often. Firstly, alcohol use was embedded within athletes’ weekly routine. Over time, drinking became a taken-for-granted ritual of sport. Secondly, specific roles and responsibilities, punishments, and events, were used to ensure athletes complied with the drinking ethos. Thirdly, athletes used alcohol to gain status and reputation. This, however, led to a culture where no behaviours were off limits and led to potentially harmful consequences. Fourthly, institutional factors (such as alcohol price, availability and sponsorship) may have normalised and legitimised a heavy drinking culture. There is a need to confront and challenge the alcohol ethos at this and other similar institutions with a pervasive drinking culture to reduce the potential harm to individual athletes.
Selective supply of atomic oxygen to a surface placed in room air using vacuum ultraviolet photolysis of carbon dioxide

Reactive species play important roles in plasma treatments of surfaces, including polymers, metals, water, and living tissues. To elucidate the surface reaction mechanism, it is crucial to measure the effect of each type of reactive species on the surface treatment. Accordingly, we previously developed a method to selectively supply OH or O radicals to a surface placed in room air. Ar/H2O or Ar/O2 gas flowing through a quartz tube is irradiated with a vacuum ultraviolet lamp, causing photodissociation of H2O and O2 to produce OH and O. The resulting gas flows to the surface from the tube end. The O density supplied to the surface, however, is only approximately 1×1012 cm−3 according to our simulation, which is not sufficient to determine the surface treatment effect of O atoms. Therefore, in this study, a new method is proposed, supplying O atoms with a density that is two orders of magnitude higher. Specifically, CO2 gas is used as the medium to be photodissociated instead of O2 gas. The performance of this method is discussed herein using simulation results. The maximum O density supplied to the surface reaches 1×1014 cm−3 according to the simulation. Additionally, the experimental results demonstrate that the newly developed method can supply a sufficient amount of O atoms to selectively measure the effect of O atoms on the surface treatment of polypropylene (PP). In particular, the water contact angle (WCA) is considered as an index of the surface treatment. As a result, O atoms decrease the WCA of the PP surface at rates of the same order of magnitude as OH.
Differential Predictability in the Use of Test Scores

THE purpose of this report is to provide an illustration of &dquo;differential predictability&dquo; in the use of test scores. It describes an attempt to improve the usefulness of a test by identifying subgroups of individuals for whom the test is especially appropriate as a predictor. To the extent that such an attempt is successful, one can predict more accurately for the members of that subgroup; for those not in the subgroup the errors of prediction will be greater, and for this subgroup one can avoid
A high accurate composite grid method for solving Laplace's boundary value problems with singularities

A sixth-order accurate composite grid method for solving a mixed boundary value problem for Laplace's equation on staircase polygons (the polygons may have polygonal cuts and be multiply connected) is constructed and justified. The O(h 6) order of accuracy for the number of nodes O(h –2 lnh –1) is obtained by using 9-point scheme on exponentially compressed polar and square grids, as well as constructing the sixth-order matching operator connecting the subsystems. This estimate is obtained for requirements on the functions specifying the boundary conditions which cannot be essentially lowered in C k,λ . Finally, we illustrate the high accuracy of the method in solving the well known Motz problem which has singularity due to abrupt changes in the type of boundary conditions.
An Empirical Study Analyzing the Moderating Effect of Supervisor Support and Mediating Effect of Presenteeism among Eustress, Distress, and Innovative Behavior

Purpose: This article aims to illustrate that stress is not always a negative experience as it can have both positive and negative outcomes. The term “eustress” describes positive stress, while the term “distress” describes negative stress. To date, research on eustress is in the infancy stage. There are approximately 306 items that can be found in the Web of Science core collection for “eustress”, while there are 184,714 items found for “distress”. Few studies have examined the relationship between presenteeism, stress, and innovative behavior. Thus, the mechanism underlying this pathway still needs to be fully understood. Materials and Methods: A survey was conducted among 350 medical healthcare professionals from Pakistan. With the help of SPSS and AMOS, the data were analyzed and the combined effects of the variables were also investigated. Results: According to the current study, a mediation effect has been observed between innovative behavior and stress (eustress and distress). However, supervisor support moderates the relationship between stress and presenteeism and, likewise, between presenteeism and innovative behavior. Conclusion: Our analysis of variables establishes empirically robust relationships between the innovative behavior of medical healthcare professionals and the two different dimensions of stress. In addition, it describes a hypothetical alternative situation that explains how employees’ innovative work behavior is affected by eustress and distress in the presence of supervisor support. This study could have implications for improving medical healthcare professionals’ ability to incorporate innovative behavior into their practice in an effective manner in the future.
Recent spread of non-indigenous ascidians (Chordata: Tunicata) in Icelandic harbours

ABSTRACT Global shipping facilitates the introduction of fouling organisms to new geographic areas. The increase in maritime transport in recent decades has led to unprecedented development, where marine coastal waters have become one of the most invaded habitats around the globe. Among the most successful invaders are ascidians. Despite the geographic and oceanographic isolation of Iceland, it is far from being excluded as a recipient region. Ascidians have successfully been able to establish stable populations in Iceland that are slowly expanding around the SW region. Here we report the first record of Ascidiella scabra in Icelandic waters, and the spread of seven non-indigenous ascidians across the S-SW Icelandic harbours. We compare their relative abundances to our survey from 2018. The bulk of these ascidians is not only present in the temperate Atlantic Ocean, but also in the Northwest Pacific and temperate Australasia, revealing that global homogenization of the ascidiofauna is emerging in anthropized coastal areas. The rising of sea surface temperature, driven by climate change, is likely to continue to support the development of this scenario leading to biodiversity loss, which could endanger living resources with severe economic impacts.
On the formation of geophysical and planetary zonal flows by near-resonant wave interactions

Numerical simulations on a β-plane are used to further understand the formation of zonal flows from small-scale fluctuations. The dynamics of ‘reduced models’ are computed by restricting the nonlinear term to include a subset of triad interactions in Fourier space. Reduced models of near-resonant triads are considered, as well as the complement set of non-resonant triads. At moderately small values of the Rhines number, near-resonant triad interactions are shown to be responsible for the generation of large-scale zonal flows from small-scale random forcing. Without large-scale drag, both the full system and the reduced model of near resonances produce asymmetry between eastward and westward jets, in favour of stronger westward jets. When large-scale drag is included, the long-time asymmetry is reversed in the full system, with eastward jets that are thinner and stronger than westward jets. Then the reduced model of near resonances exhibits a weaker asymmetry, but there are nevertheless more eastward jets stronger than a threshold value.
Application of spatial transcriptome technologies to neurological diseases

Spatial transcriptome technology acquires gene expression profiles while retaining spatial location information, it displays the gene expression properties of cells in situ. Through the investigation of cell heterogeneity, microenvironment, function, and cellular interactions, spatial transcriptome technology can deeply explore the pathogenic mechanisms of cell-type-specific responses and spatial localization in neurological diseases. The present article overviews spatial transcriptome technologies based on microdissection, in situ hybridization, in situ sequencing, in situ capture, and live cell labeling. Each technology is described along with its methods, detection throughput, spatial resolution, benefits, and drawbacks. Furthermore, their applications in neurodegenerative disease, neuropsychiatric illness, stroke and epilepsy are outlined. This information can be used to understand disease mechanisms, pick therapeutic targets, and establish biomarkers.
Encephalitis following COVID-19 Vaccination: A Systematic Review

Background: Since the advent of global COVID-19 vaccination, several studies reported cases of encephalitis with its various subtypes following COVID-19 vaccinations. In this regard, we conducted a systematic review to investigate and characterize the clinical settings of these reported cases to aid in physician awareness and proper care provision. Methods: We systematically searched PubMed, Web of Science, and Scopus and manually searched Google Scholar. Studies published until October 2022 were included. Demographic data, clinical features, vaccine data, treatment lines, and outcomes were extracted. Results: A total of 65 patients from 52 studies were included. The mean age of patients was 46.82 ± 19.25 years, 36 cases (55.4%) were males. AstraZeneca was the most-reported vaccine associated with encephalitis (38.5%) followed by Pfizer (33.8%), Moderna (16.9%), and others. Moat encephalitis cases occurred after the first dose of vaccination in 41/65 (66.1%). The mean time between vaccination and symptom onset was 9.97 ± 7.16 days. Corticosteroids (86.2 %) and immunosuppressants (81.5 %) were the most used lines of treatment. The majority of affected individuals experienced a full recovery. Conclusion: Our study summarizes the current evidence of reported post-vaccination encephalitis, regarding clinical presentation, symptoms onset, management, outcomes, and comorbid conditions; however, it fails to either acknowledge the incidence of occurrence or establish a causal relationship between various COVID-19 vaccines and encephalitis.
Solar wind ionization temperatures inferred from the charge state composition of diffuse particle events

The charge state composition of heavy ions, primarily the carbon-nitrogen-oxygen (CNO) group, has been determined for 12 diffuse particle events in the energy-per-charge range ∼33 to 132 keV/e observed upstream of the earth's bow shock. The measurements were made with the University of Maryland/Max-Planck-Institut ultra low energy charge analyzer (ULECA) sensor on ISEE 1. The relative charge state distributions found for Q ≥ 3 ions at ∼33, 66, and 132 keV/e are consistent with a charge state composition that is constant as a function of energy per charge. It is suggested that the charge state composition of these locally accelerated heavy ions can be used to estimate the charge state composition in the solar wind and hence to estimate the equilibrium coronal temperatures associated with a variety of solar wind flows. In particular, we obtain average CNO ionization temperatures of (1.5±0.2) ×106 K for diffuse particle events occurring during interstream solar wind conditions, (1.3± 0.2) × 106 K for events occurring during coronal-hole-associated high-speed streams, and (2.2±0.3) × 106 K for events occurring during transient-related flows. The diffuse particle event ionization temperatures corresponding to coronal-hole-associated high-speed streams are particularly interesting, since reported solar wind charge state measurements for high-speed streams are presently very limited. The temperature values we infer for coronal-hole-associated solar wind are approximately constant over the range of solar wind speeds covered (420–680 km s−1) and are consistent with equilibrium temperatures predicted for coronal holes.
Volume Scanning Strategies for 3D Wind Retrieval from Dual-Doppler Lidar Measurements

Abstract Dual-Doppler lidar volume scans for 3D wind retrieval must accommodate the conflicting goals of dense spatial coverage and short scan duration. In this work, various scanning strategies are evaluated with semisynthetic wind fields from analytical solutions and numerical simulations over flat and complex terrain using the Multiple-Doppler Synthesis and Continuity Adjustment Technique (MUSCAT) retrieval algorithm. The focus of this study is to determine how volume scan strategies affect performance of the wind retrieval algorithm. Interlaced scanning methods that take into account actual maximum measurement ranges are found to be optimal because they provide the best trade-off between retrieval accuracy, volume coverage, and scan time. A recommendation for scanning strategies is given, depending on actual measurement ranges, the variability of the wind situation, and the trade-off between spatial coverage and temporal smoothing.
The Use of Gemtuzumab Ozogamicin as Salvage Therapy in Patients with Acute Myeloid Leukemia: A Monocentric Real-World Experience

Background and Objectives: Relapsed or refractory acute myeloid leukemia (r/r AML) is a disease with a poor prognosis. Limited treatment options are available in r/r AML. Here, we administered gemtuzumab ozogamicin (GO) as salvage therapy in twenty-four patients with r/r AML. The aim of the study was to determine the role of GO in r/r AML in real life. Material and Methods: This retrospective observational study recruited 24 adult patients with diagnosed r/r AML from 2018 to 2022. Twenty-four patients with r/r AML were treated with GO. GO treatment was used as monotherapy in 23 patients and in combination with cytarabine in 1 patient. At the time of diagnosis, the risk status of all patients was determined as favorable, intermediate, or adverse according to the 2017 ELN AML guidelines. Results: The median follow-up was 44.3 (13–144) months. Fifteen (62.5%) of the twenty-four patients were in the intermediate-risk cytogenetics group and nine (37.5%) were in the favorable cytogenetics group. The most common adverse events included nausea/vomiting in 79.17% (n = 19) of patients, headache in 62.50% (n = 15), elevated LFTs in 37.50% (n = 9), febrile neutropenia in 25% (n = 6), and bleeding in 25% (n = 6). The most common cause of death was infection. The most common causes of mortality were septic shock, accounting for 33.3% (n = 8) of deaths, and opportunistic lung infection, accounting for 12.5% (n = 3) of deaths. Acute infusion-related toxicities associated with GO were usually transient and, in most cases, responded to the standard of care treatment. After treatment with GO, 16.6% (n = 4) of patients achieved MLFS and 37.5% (n = 9) achieved CR. The overall response rate was 54.1%. The median overall survival time of the patients was 44 months (37.8–50.2 months). Disease-free survival was 22 months (0–48.6 months). The 5-year survival rate was 33%. Conclusions: A low dose of GO improved the overall survival and disease-free survival in r/r AML patients. GO treatment had a positive safety profile in terms of toxicity.
