Published: March 2022

AbstractNowadays, geopolymers, which are more environmentally friendly than cement due to the high energy requirements and high carbon dioxide (CO2) emissions of cement production, emerge as alternative binders. In this study, the mechanical and durability properties of geopolymer concrete (GC) based on ground granulated blast furnace slag (GGBS) (100GGBS), 50% fly ash (FA) and 50% GGBS (50FA50GGBS), and FA (100FA) with two different water/geopolymer solids ratios (W/GP) of 0.33 and 0.35 were investigated. Slump, compressive strength, splitting tensile strength, unit weight, water absorption, elevated temperature resistance, abrasion resistance, modulus of elasticity, and drying shrinkage tests were carried out. As the percentage of FA in the mixture increased, the slump of the concrete increased, while the cohesion of the concrete decreased and the setting time was delayed. The addition of GGBS increased the compressive strength and the splitting tensile strength of the GC by up to 377% and 278%, respectively. Under the effect of elevated temperature, the 100FA concrete showed less strength loss and weight loss than other concrete. After the abrasion test, 100GGBS concrete lost about 2.5 times less weight than 100FA concrete. The drying shrinkage of geopolymer mortar reached a maximum of 100 microstrains. Among all concrete, 50FA50GGBS‐0.33 showed the highest performance in terms of overall performance.
What corporations can learn from the struggle in the market for souls
Authors: Behrens Alfredo 
Published: March 2022

AbstractThe pace and extent of expanding religions holds essential lessons for business leaders and their corporations' international growth style. Monotheistic religions overtook polytheistic ones and the proselytizing religions expanded faster and farther. This lesson underscores the importance of alignment, as well as suggesting that corporations grow through acquisitions and promoting greater permeability at headquarters. This would improve the international allocation of headquarter capabilities as well as allow faster deployment of the talents acquired through global expansion.
A call for a critical urban climatology: Lessons from critical physical geography
Authors: Beray‐Armond Núbia 
Published: March 2022

AbstractUrban climatology and environmental justice frequently share the same research site: the city. However, they study urban areas in distinct ways. Urban climatology has contributed to a better understanding of the urban boundary and canopy layer climates by embracing a broader and deeper investigation of the atmospheric and climatic specificities of the cities. Environmental justice has contributed a better understanding of how the poor and people of color are disproportionally affected by environmental problems. I argue here that we need both fields to fully understand urban climates because they are shaped both by legacies of colonialism, and race, gender, and class, and by the particularities of urban energy budgets and the variation in intra‐urban air quality and thermal‐hygrometric characteristics they drive. Critical physical geography can provide important analytical, theoretical, and methodological tools to help urban climatologists and environmental justice scholars work together toward the goal of social and environmental transformation.This article is categorized under:

Österreich in der ersten Phase der Covid-19-Pandemie
Authors: Aschauer Wolfgang , Prandner Dimitri , Glatz Christoph 
Published: March 2022

ZusammenfassungMit der Covid-19-Pandemie, die das gesellschaftliche Leben ab März 2020 in Österreich massiv eingeschränkt hat, haben wir es mit der größten gesundheitlichen, ökonomischen und sozialen Herausforderung seit Jahrzehnten zu tun. Zunehmend rücken dabei auch die sozialen Folgen der Pandemie in den Fokus der Öffentlichkeit. Zusammenfassend umreißen wir in der Einleitung jene Themen, die in weiterer Folge auch in den Beiträgen im Vordergrund stehen. Es sind dies die weitreichenden Eingriffe der Pandemie in den Lebensalltag der Bevölkerung, Solidaritätspotentiale in der Gesellschaft, Dynamiken sozialer Ungleichheit sowie Werteverschiebungen und Zukunftserwartungen zur weiteren gesellschaftlichen Entwicklung. Das Ziel des vorliegenden Sammelbands ist es, empirische Befunde, die auf mehreren Umfrageprojekten während der Pandemie basieren, in die Gesellschaft zu tragen und dadurch tiefergehende Reflexionen über die österreichische Gesellschaft während der Corona-Pandemie zu ermöglichen.
Informationsverhalten und Glaubwürdigkeit von Medien in der Krise
Authors: Prandner Dimitri 
Published: March 2022

ZusammenfassungKlare und korrekte Informationen sind in Krisensituationen von gesamtgesellschaftlicher Relevanz. Wie sich die Österreicher*innen während der ersten Welle der Covid-19-Pandemie informiert haben und welche medialen Informationsquellen sie als glaubwürdig beurteilten steht im Zentrum des Beitrags. Auf Basis derValues in Crisis-Studie kann gezeigt werden, dass sich das allgemeine Informationsverhalten in der Krise nur wenig verändert hat, aber der Einfluss der sozialen Ungleichheit auf die Mediennutzung im Vergleich zu vorherigen Studien weniger deutlich ausgeprägt ist. Das Fernsehen stellte erwartungsgemäß die wichtigste Informationsquelle für die befragten Österreicher*innen dar. Die Bedeutung von sozialen Medien und Onlinenachrichtenseiten nimmt aber kontinuierlich zu und ist, besonders bei jüngeren Personen, im Ansteigen begriffen. Effekte von sozialen Ungleichheiten zeigten sich bei der Beurteilung von Medieninhalten hinsichtlich ihrer Glaubwürdigkeit. Personen in besserer sozialer Position glauben eher journalistischen Nachrichtenquellen. Dies ist vor dem Hintergrund, dass journalistische Inhalte helfen sollten das gesellschaftliche Zusammenleben zu organisieren von Bedeutung. Die Ergebnisse deuten darauf hin, dass weniger privilegierte Personengruppen medial übermittelte Handlungsanweisungen weniger glaubhaft finden und dementsprechend auch potenziell ihr Verhalten weniger stark an die Gegebenheiten anpassen als gewünscht.
Soziales Vertrauen und Solidarität in Zeiten der Krise
Authors: Bodi-Fernandez Otto , Grausgruber Alfred , Glatz Christoph 
Published: March 2022

ZusammenfassungGesellschaftlicher Zusammenhalt, Solidarität und Vertrauen sind während der Corona-Krise zu viel beschworenen Schlagwörtern geworden. Sie stehen für eine Form sozialen Kapitals, das in Zeiten der Krise eine wesentliche Ressource zu deren Bewältigung darstellen soll und auch von politischer und medizinischer Seite oftmals eingefordert wird. Eng verbunden mit dem Begriff der Solidarität ist jener des sozialen Vertrauens. Das Vertrauen in andere Menschen sowie in zentrale gesellschaftliche Institutionen wird als wichtige Komponente des Sozialkapitals einer Gesellschaft betrachtet und gilt als wesentliche Grundlage für den gesellschaftlichen Zusammenhalt. Das Buchkapitel beschäftigt sich mit der Solidarität und dem sozialen Vertrauen in der österreichischen Bevölkerung während der ersten Welle der Covid-19-Pandemie anhand der Daten des Austrian Corona Panel Projects. Untersucht wird, wie sich das Ausmaß des sozialen Vertrauens im Vergleich zu früher verändert hat und inwieweit es Unterschiede zwischen verschiedenen Bevölkerungsgruppen gibt, die von der Pandemie besonders betroffen sind (z. B. Vorerkrankte, Personen in beengten Wohnverhältnissen, Alleinlebende, Eltern von schulpflichtigen Kindern, Alleinerziehende, beruflich Betroffene). Des Weiteren wird untersucht, wie sich die Wahrnehmung des gesellschaftlichen Zusammenhalts während der Zeit der Covid-19-Pandemie entwickelt hat, inwieweit sich solidarisches Handeln in verschiedenen Personengruppen unterscheidet und in welchem Ausmaß soziales Vertrauen zum solidarischen Handeln beiträgt.
Homes’ law in holographic superconductor with linear-T resistivity
Authors: Jeong Hyun-Sik , Kim Keun-Young 
Published: March 2022

Abstract
Homes’ law, ρs = CσDCTc, is a universal relation of superconductors between the superfluid density ρs at zero temperature, the critical temperature Tc and the electric DC conductivity σDC at Tc. Experimentally, Homes’ law is observed in high Tc superconductors with linear-T resistivity in the normal phase, giving a material independent universal constant C. By using holographic models related to the Gubser-Rocha model, we investigate how Homes’ law can be realized together with linear-T resistivity in the presence of momentum relaxation. We find that strong momentum relaxation plays an important role to exhibit Homes’ law with linear-T resistivity.
Pseudo and quasi gluon PDF in the BFKL approximation
Authors: Chirilli Giovanni Antonio 
Published: March 2022

Abstract
I study the behavior of the gauge-invariant gluon bi-local operator with space- like separation at large longitudinal distances. Performing the Fourier transform, I also calculate the behavior of the pseudo and quasi gluon PDF at low Bjorken x and compare it with the leading and next-to-leading twist approximation. I show that the pseudo-PDF and quasi-PDF are very different at this regime and that the higher twist corrections of the quasi-PDF come in not as inverse powers of P but as inverse powers of xBP.
Fractional truncated Laplacians: representation formula, fundamental solutions and applications
Authors: Birindelli Isabeau , Galise Giulio , Topp Erwin 
Published: March 2022

AbstractWe introduce some nonlinear extremal nonlocal operators that approximate the, so called, truncated Laplacians. For these operators we construct representation formulas that lead to the construction of what, with an abuse of notation, could be called “fundamental solutions”. This, in turn, leads to Liouville type results. The interest is double: on one hand we wish to “understand” what is the right way to define the nonlocal version of the truncated Laplacians, on the other, we introduce nonlocal operators whose nonlocality is on one dimensional lines, and this dramatically changes the prospective, as is quite clear from the results obtained that often differ significantly with the local case or with the case where the nonlocality is diffused. Surprisingly this is true also for operators that approximate the Laplacian.

Published: March 2022

AbstractBackgroundWith the global pandemic of obesity and nonalcoholic fatty liver disease (NAFLD), the incidence of cirrhosis associated with nonalcoholic steatohepatitis (NASH) has greatly increased. This study aimed to evaluate the efficacy and safety of bariatric surgery in obese cirrhotic patients.MethodsPubMed, EMBASE, and the Cochrane Library were searched for relevant studies. Effectiveness outcomes were weight loss, remission of comorbidities, and improvement in liver function. Safety outcomes were procedural complications and mortality.ResultsA total of 15 studies were included in this meta‐analysis. Patients with compensated cirrhosis lost weight significantly after surgery, and the percentage of excess weight loss was 60.44 (95% CI, 44.34 to 76.55). Bariatric surgery resulted in remission of NAFLD in 57.9% (95% CI, 27.5% to 88.3%), T2DM in 58.4% (95% CI, 48.4% to 68.4%), hypertension in 53.1% (95% CI, 43% to 63.3%), dyslipidemia in 59.8% (95% CI, 41.1% to 78.5%) of patients with cirrhosis. Bariatric surgery reduced the levels of alanine aminotransferase and aspartate aminotransferase. The incidence of surgical complications in patients with cirrhosis was about 19.2% (95% CI, 11.7% to 26.6%), which was higher than that in patients without cirrhosis (OR 2.67 [95% CI, 1.26 to 5.67]). Patients with cirrhosis had an overall mortality rate of 1.3%, and the mortality rates for compensated cirrhosis and decompensated cirrhosis were 0.9% and 18.2%, respectively.ConclusionsBariatric surgery is effective for weight loss, remission of comorbidities, and reversal of liver damage. Although cirrhotic patients have a higher risk of complications and death, bariatric surgery is relatively safe for well‐compensated cirrhosis.

Abstract
Background
The COVID-19 pandemic had an unprecedented impact on clinical practice and healthcare professionals. We aimed to assess how interventional radiology services (IR services) were impacted by the pandemic and describe adaptations to services and working patterns across the first two waves.

Methods
An anonymous six-part survey created using an online service was distributed as a single-use web link to 7125 members of the Cardiovascular and Interventional Radiological Society of Europe via email. Out of 450 respondents, 327 who completed the survey at least partially including 278 who completed the full survey were included into the analysis.

Results
Interventional radiologists (IRs) reported that the overall workload decreased a lot (18%) or mildly (36%) or remained stable (29%), and research activities were often delayed (30% in most/all projects, 33% in some projects). Extreme concerns about the health of families, patients and general public were reported by 43%, 34% and 40%, respectively, and 29% reported having experienced significant stress (25% quite a bit; 23% somewhat). Compared to the first wave, significant differences were seen regarding changes to working patterns, effect on emergency work, outpatient and day-case services in the second wave. A total of 59% of respondents felt that their organisation was better prepared for a third wave. A total of 19% and 39% reported that the changes implemented would be continued or potentially continued on a long-term basis.

Conclusion
While the COVID-19 pandemic has negatively affected IR services in terms of workload, research activity and emotional burden, IRs seem to have improved the own perception of adaptation and preparation for further waves of the pandemic.
Analytic approximation for the collapse of viscous tubes driven by surface tension and pressure difference
Authors: Sanders Tarun M. , Putrino Gino , Keating Adrian 
Published: March 2022

AbstractIn this work, an approximate analytic formula is developed which accurately models the one-dimensional collapse kinetics of viscous glass tubes, driven by surface tension and low-to-moderate pressure differences. This is in contrast to existing analytic approaches from the literature where either surface tension is the only driving force, or extremely high pressure differences are assumed. Extensive model validation is provided against numerical computation of the exact one-dimensional and two-dimensional models for cross-sectional collapse, as well as with experimental data from the literature. Practical utility of this formula is demonstrated for effortlessly solving the inverse problem for determining the viscosity and surface tension of glass tubes.
Bullying behavior and employee well-being: how do different forms of social support buffer against depression, anxiety and exhaustion?
Authors: Pauksztat Birgit , Salin Denise , Kitada Momoko 
Published: March 2022

AbstractPurposeWorkplace bullying has severe negative consequences for the well-being of targeted employees. Previous research suggests that social support may buffer against such adverse effects. However, it remains unclear if different forms of support have equally strong effects and if support buffers equally effectively against different outcomes. Further, little is known about social support as a mitigating factor in remote occupational groups such as seafarers. This study examines the buffering effects of four forms of support (instrumental and emotional peer support, company support, non-work support) on three aspects of employee well-being (depression, anxiety, and exhaustion) among seafarers.MethodsResponses to a cross-sectional online survey from a convenience sample of 414 seafarers on international commercial vessels were analyzed using moderated regression analyses with PROCESS.ResultsExposure to workplace bullying behavior increased seafarers’ depression, anxiety and exhaustion. Instrumental peer support and non-work support buffered the negative impact of bullying on depression. The impact of bullying on exhaustion was buffered by company support. The impact of bullying on anxiety was not buffered by any of the four forms of support.ConclusionExtending previous research, the findings suggest that the interaction between workplace bullying and support depends not only on the source of support, but also on the type of support and the outcome considered. While support from colleagues on board was important for seafarers, company and non-work support must not be overlooked. Interventions should, therefore, encourage the development of peer support and ensure access to shore-based support for workers in remote locations.

AbstractSoluble fibrin (SF) in blood consists of monomers lacking both fibrinopeptides A with a minor population in multimeric clusters. It is a substantial component of isolated fibrinogen (fg), which spontaneously self-assembles into protofibrils progressing to fibers at sub-physiologic temperatures, a process enhanced by adsorption to hydrophobic and some metal surfaces. Comparisons of SF-rich (FR) and SF-depleted (FD) fg isolates disclosed distinct molecular imprints of each via an adsorption/desorption procedure using gold surfaced silica microplates. Accelerated plasminogen activator-induced lysis and decreased stiffness (G′) of thrombin-induced FR fg clots were revealed by thomboelastography. Erythrocyte sedimentation (ESR) in afibrinogenemic plasma (Hematocrit 25–33%) was accelerated by FR fg nearly threefold that of FD fg. Stained smears disclosed frequent rouleaux formations and fibers linking stacked erythrocytes in contrast to no rouleaux by FD fg. Rouleaux formations were more pronounced at 4 °C than at ambient temperatures and at fiber-membrane contacts displayed irregular, knobby membrane contours. One of several FR fg isolates also displayed incomplete fiber networks in cell-free areas. What is more, pre-mixing FR fg with each of three monoclonal IgG anti-fg antibodies at 1.5 mol/mol fg, that inhibited fibrin polymerization, prevented rouleaux formation save occasional 2–4 erythrocyte aggregates. We conclude that spontaneously generated SF fibers bound to erythrocytes forming intercellular links culminating in rouleaux formation and ensuing ESR acceleration which in clinical settings reflects hypercoagulability. Also, the results can explain the reported fg binding to erythrocytes via ligands such as CD47, stable in vivo RBC aggregates in capillaries, and red areas of pathologic thrombi.

Published: March 2022

AbstractParkinson’s disease (PD) is a neurological disease that has been reported to have affected most people worldwide. Recent research pointed out that about 90% of PD patients possess voice disorders. Motivated by this fact, many researchers proposed methods based on multiple types of speech data for PD prediction. However, these methods either face the problem of low rate of accuracy or lack generalization. To develop an approach that will be free of these issues, in this paper we propose a novel ensemble approach. These paper contributions are two folds. First, investigating feature selection integration with deep neural network (DNN) and validating its effectiveness by comparing its performance with conventional DNN and other similar integrated systems. Second, development of a novel ensemble model namely EOFSC (Ensemble model with Optimal Features and Sample Dependant Base Classifiers) that exploits the findings of recently published studies. Recent research pointed out that for different types of voice data, different optimal models are obtained which are sensitive to different types of samples and subsets of features. In this paper, we further consolidate the findings by utilizing the proposed integrated system and propose the development of EOFSC. For multiple types of vowel phonations, multiple base classifiers are obtained which are sensitive to different subsets of features. These features and sample-dependent base classifiers are integrated, and the proposed EOFSC model is constructed. To evaluate the final prediction of the EOFSC model, the majority voting methodology is adopted. Experimental results point out that feature selection integration with neural networks improves the performance of conventional neural networks. Additionally, feature selection integration with DNN outperforms feature selection integration with conventional machine learning models. Finally, the newly developed ensemble model is observed to improve PD detection accuracy by 6.5%.

Published: March 2022

Abstract
Purpose
Intraforaminal ligaments (IFL) are of great interest to anatomists and clinicians to fully understand the detailed anatomy of the neuroforamina and to diagnose unclear radicular symptoms. Studies published until now have described radiological imaging of the IFLs using magnetic resonance imaging (MRI) on donor bodies. In the present study, we investigated the detectability of lumbar IFLs in vivo in adults using the high spatial resolution of the constructive interference in steady state (CISS) sequence.

Methods
A total of 14 patients were studied using a 1.5 T MRI scanner. The lumbar spine was imaged using the parasagittal CISS sequence, and the detectability of the IFLs was assessed for each lumbar level. All image datasets were analyzed by a radiologist, an orthopedic surgeon, and an anatomist. Interrater reliability was expressed as Fleiss’ Kappa. Using a single data set, a three-dimensional (3D) model was created to map the location of the IFLs within the intervertebral foramen (IF) and the immediate surrounding vessels.

Results
Overall, the radiologist was able to detect IFLs in 60% of all imaged IFs, the orthopedic surgeon in 62%, and the anatomist in 66%. Fleiss’ Kappa for the various segments varies from 0.71 for L4/5 up to 0.90 for L3/4.

Conclusion
Lumbar IFLs were successfully detected in vivo in every patient. The detection frequency varied from 42–86% per IF. We demonstrated reproducible imaging of the IFLs on MRI, with good interrater reliability. The present study was a launching point for further clinical studies investigating the potential impact of altered IFLs on radicular pain.
