Published: December 2021

This Letter proposes the use of atomic layer deposition (ALD) encapsulation as a stability-improving approach for a quantum-dot micro-structural array (QDMA) with a random rough interface. The QDMA is first prepared by screen printing technology on an edge-lit light-guide plate (LGP) for backlight application. A flexible aluminum oxide film is then densely deposited onto the rough surface of the QDMA. The influences of two key factors, the reaction temperature and deposition thickness, on the encapsulation effect and output performance of this QD backlight are discussed. After ALD encapsulation, the water vapor transmission rate was measured to be less than 0.014 g/(m2 day). The average luminance of the encapsulated QD backlight remained stable after continuous working for 200 h, while an unencapsulated QD backlight lost over 50% of its initial luminance. The complete attenuation trend for the encapsulated QD backlight was analyzed in a more demanding testing environment, and results showed that 80% (>3000 cd/m2) of the initial luminance was maintained after 250 h at a high temperature of 70 °C and a relative humidity of 90%. The mechanism behind these experimental results is also discussed.

Published: December 2021

We present a spatiotemporally mode-locked Mamyshev oscillator. A wide variety of multimode mode-locked states, with varying degrees of spatiotemporal coupling, are observed. We find that some control of the modal content of the output beam is possible through the cavity design. Comparison of simulations with experiments indicates that spatiotemporal mode locking (STML) is enabled by nonlinear intermodal interactions and spatial filtering, along with the Mamyshev mechanism. This work represents a first, to the best of our knowledge, exploration of STML in an oscillator with a Mamyshev saturable absorber.

Published: December 2021

The development of super-resolution imaging has driven research into biological labeling, new materials’ characterization, and nanoscale sensing. Here, we studied the photoinduced charge state conversion of nitrogen-vacancy (NV) centers in nanodiamonds (NDs), which show the potential for multifunction sensing and labeling at the nanoscale. Charge state depletion (CSD) nanoscopy is subsequently demonstrated for the diffraction-unlimited imaging of NDs in biological cells. A resolution of 77 nm is obtained with 50 nm NDs. The depletion laser power of CSD nanoscopy is approximately 1/16 of stimulated emission depletion (STED) microscopy with the same resolution. The results can be used to improve the spatial resolution of biological labeling and sensing with NDs and other nanoparticles.
Dynamic maximum entropy provides accurate approximation of structured population dynamics
Authors: Bod’ová Katarína , Szép Enikő , Barton Nicholas H.
Published: December 2021

Realistic models of biological processes typically involve interacting components on multiple scales, driven by changing environment and inherent stochasticity. Such models are often analytically and numerically intractable. We revisit a dynamic maximum entropy method that combines a static maximum entropy with a quasi-stationary approximation. This allows us to reduce stochastic non-equilibrium dynamics expressed by the Fokker-Planck equation to a simpler low-dimensional deterministic dynamics, without the need to track microscopic details. Although the method has been previously applied to a few (rather complicated) applications in population genetics, our main goal here is to explain and to better understand how the method works. We demonstrate the usefulness of the method for two widely studied stochastic problems, highlighting its accuracy in capturing important macroscopic quantities even in rapidly changing non-stationary conditions. For the Ornstein-Uhlenbeck process, the method recovers the exact dynamics whilst for a stochastic island model with migration from other habitats, the approximation retains high macroscopic accuracy under a wide range of scenarios in a dynamic environment.

Published: December 2021

Observing social/physical distancing norms between humans has become an indispensable precaution to slow down the transmission of COVID-19. We present a novel method to automatically detect pairs of humans in a crowded scenario who are not maintaining social distancing, i.e. about 2 meters of space between them using an autonomous mobile robot and existing CCTV (Closed-Circuit TeleVision) cameras. The robot is equipped with commodity sensors, namely an RGB-D (Red Green Blue—Depth) camera and a 2-D lidar to detect social distancing breaches within their sensing range and navigate towards the location of the breach. Moreover, it discreetly alerts the relevant people to move apart by using a mounted display. In addition, we also equip the robot with a thermal camera that transmits thermal images to security/healthcare personnel who monitors COVID symptoms such as a fever. In indoor scenarios, we integrate the mobile robot setup with a static wall-mounted CCTV camera to further improve the number of social distancing breaches detected, accurately pursuing walking groups of people etc. We highlight the performance benefits of our robot + CCTV approach in different static and dynamic indoor scenarios.

Published: December 2021

There continue to be conflicting data regarding the outcomes of people with HIV (PWH) who have COVID-19 infection with most studies describing the early epidemic. We present a single site experience spanning a later timeframe from the first report on January 21, 2020 to January 20, 2021 and describe clinical outcomes and predictors of hospitalization among a cohort of PWH in an urban center in Connecticut, USA. Among 103 PWH with controlled HIV disease, hospitalization occurred in 33% and overall mortality was 1%. HIV associated factors (CD4 count, HIV viral suppression) were not associated with hospitalization. Chronic lung disease (OR: 3.35, 95% CI:1.28–8.72), and cardiovascular disease (OR: 3.4, 95% CI:1.27–9.12) were independently associated with hospitalization. An increasing number of non-communicable comorbidities increased the likelihood of hospitalization (OR: 1.61, 95% CI:1.22–2.13).

Published: December 2021

Background

It has been a matter of much debate whether the co-administration of furosemide and albumin can achieve better diuresis and natriuresis than furosemide treatment alone. There is inconsistency in published trials regarding the effect of this combination therapy. We, therefore, conducted this meta-analysis to explore the efficacy of furosemide and albumin co-administration and the factors potentially influencing the diuretic effect of such co-administration.

Methods

In accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we searched the PubMed, Embase, Medline, and Cochrane databases. Prospective studies with adult populations which comparing the effect of furosemide and albumin co-administration with furosemide alone were included. The outcomes including diuretic effect and natriuresis effect measured by hourly urine output and hourly urine sodium excretion from both groups were extracted. Random effect model was applied for conducting meta-analysis. Subgroup analysis and sensitivity analysis were performed to explore potential sources of heterogeneity of treatment effects.

Results

By including 13 studies with 422 participants, the meta-analysis revealed that furosemide with albumin co-administration increased urine output by 31.45 ml/hour and increased urine excretion by 1.76 mEq/hour in comparison to furosemide treatment alone. The diuretic effect of albumin and furosemide co-administration was better in participants with low baseline serum albumin levels (< 2.5 g/dL) and high prescribed albumin infusion doses (> 30 g), and the effect was more significant within 12 hours after administration. Diuretic effect of co-administration was better in those with baseline Cr > 1.2 mg/dL and natriuresis effect of co-administration was better in those with baseline eGFR < 60 ml/min/1.73m2.

Conclusion

Co-administration of furosemide with albumin might enhance diuresis and natriuresis effects than furosemide treatment alone but with high heterogeneity in treatment response. According to the present meta-analysis, combination therapy might provide advantages compared to the furosemide therapy alone in patients with baseline albumin levels lower than 2.5 g/dL or in patients receiving higher albumin infusion doses or in patients with impaired renal function. Owing to high heterogeneity and limited enrolled participants, further parallel randomized controlled trials are warranted to examine our outcome.

Simulating the impact of piers on hydrodynamics and pollutant transport: A case study in the Middle Yangtze River
Authors: Xiong Haibin , Chen Li , Sun Zhaohua , Li Zhiqing , Zhou Kun , Chen Zhenghao
Published: December 2021

It is known that channel engineering, including the construction of piers, will change the river hydrodynamic characteristics, which is a significant factor affecting the transport process of pollutants. With this regard, this study uses the well-validated and tested hydrodynamic module and transport module of MIKE 21 to simulate the hydrodynamics and water quality under various pier densities in the Wuhan reach. Hydrodynamic changes around the piers show spatial differences, which are similar under different discharges. The range and amplitude of hydrodynamic spatial variations increase with the increase in pier density. However, there is a critical value of 1.25 to 2.5 units/km. When the pier density is less than this critical value, this type of cumulative effect is the most significant. Additionally, greater changes can be found in chemical oxygen demand concentrations, which also show spatial and temporal variations. The area with high chemical oxygen demand concentration upstream and downstream from the engineering area exhibits the distribution characteristics of “decrease in the downstream area and increase in the upstream area” and “increase in downstream the area and decrease in the upstream area” respectively. In the reach section of the engineering area, the area with high chemical oxygen demand concentration increases in the front area near the piers and decreases near the shoreline. Furthermore, the concentration shows attenuation actions with a longer residence time owing to the buffering effect of pier groups. These results have significant implications on shoreline planning and utilization. Moreover, they provide scientific guidelines for water management.

Published: December 2021

Hypertensive disorders in pregnancy (HDP) are associated with increased risk of offspring neurodevelopmental disorders, suggesting long-term adverse impacts on fetal brain development. However, the relationship between HDP and deficits in general child development is unclear. Our objective was to assess the association between HDP and motor and cognitive developmental delay in children at 36 months of age. We analyzed data from the All Our Families community-based cohort study (n = 1554). Diagnosis of HDP–gestational or chronic hypertension, preeclampsia, or eclampsia–was measured through medical records. Child development was measured by maternal-report on five domains of the Ages and Stages Questionnaire (ASQ-3). Standardized cut-off scores were used to operationalize binary variables for any delay, motor delay, and cognitive delay. We calculated adjusted risk ratios (aRRs) and 95% confidence intervals (CIs) using logistic regression, sequentially controlling for potential confounders followed by factors suspected to lie on the causal pathway. Overall, 8.0% of women had HDP and hypertension-exposed children had higher prevalence of delay than unexposed children. Hypertension-exposed children had elevated risk for developmental delay, but CIs crossed the null. The aRRs quantifying the fully adjusted effect of HDP on child development were 1.19 (95% CI 0.92, 1.53) for any delay, 1.18 (95% CI 0.86, 1.61) for motor delay, and 1.24 (95% CI 0.83, 1.85) for cognitive delay. We did not find a statistically significant association between HDP and developmental delay. Confidence intervals suggest that children exposed to HDP in utero have either similar or slightly elevated risk of any, motor, and cognitive delay at 36 months after controlling for maternal and obstetric characteristics. The observed direction of association aligns with evidence of biological mechanisms whereby hypertensive pathology can disrupt fetal neurodevelopment; however, more evidence is needed. Findings may have implications for early developmental monitoring and intervention following prenatal hypertension exposure.

Purpose

Accurate liver segmentation is key for volumetry assessment to guide treatment decisions. Moreover, it is an important pre-processing step for cancer detection algorithms. Liver segmentation can be especially challenging in patients with cancer-related tissue changes and shape deformation. The aim of this study was to assess the ability of state-of-the-art deep learning 3D liver segmentation algorithms to generalize across all different Barcelona Clinic Liver Cancer (BCLC) liver cancer stages.

Methods

This retrospective study, included patients from an institutional database that had arterial-phase T1-weighted magnetic resonance images with corresponding manual liver segmentations. The data was split into 70/15/15% for training/validation/testing each proportionally equal across BCLC stages. Two 3D convolutional neural networks were trained using identical U-net-derived architectures with equal sized training datasets: one spanning all BCLC stages (“All-Stage-Net": AS-Net), and one limited to early and intermediate BCLC stages (“Early-Intermediate-Stage-Net": EIS-Net). Segmentation accuracy was evaluated by the Dice Similarity Coefficient (DSC) on a dataset spanning all BCLC stages and a Wilcoxon signed-rank test was used for pairwise comparisons.

Results

219 subjects met the inclusion criteria (170 males, 49 females, 62.8±9.1 years) from all BCLC stages. Both networks were trained using 129 subjects: AS-Net training comprised 19, 74, 18, 8, and 10 BCLC 0, A, B, C, and D patients, respectively; EIS-Net training comprised 21, 86, and 22 BCLC 0, A, and B patients, respectively. DSCs (mean±SD) were 0.954±0.018 and 0.946±0.032 for AS-Net and EIS-Net (p<0.001), respectively. The AS-Net 0.956±0.014 significantly outperformed the EIS-Net 0.941±0.038 on advanced BCLC stages (p<0.001) and yielded similarly good segmentation performance on early and intermediate stages (AS-Net: 0.952±0.021; EIS-Net: 0.949±0.027; p = 0.107).

Conclusion

To ensure robust segmentation performance across cancer stages that is independent of liver shape deformation and tumor burden, it is critical to train deep learning models on heterogeneous imaging data spanning all BCLC stages.
Neural correlates of acoustic dissonance in music: The role of musicianship, schematic and veridical expectations
Authors: Pagès-Portabella Carlota , Bertolo Mila , Toro Juan M.
Published: December 2021

In western music, harmonic expectations can be fulfilled or broken by unexpected chords. Musical irregularities in the absence of auditory deviance elicit well-studied neural responses (e.g. ERAN, P3, N5). These responses are sensitive to schematic expectations (induced by syntactic rules of chord succession) and veridical expectations about predictability (induced by experimental regularities). However, the cognitive and sensory contributions to these responses and their plasticity as a result of musical training remains under debate. In the present study, we explored whether the neural processing of pure acoustic violations is affected by schematic and veridical expectations. Moreover, we investigated whether these two factors interact with long-term musical training. In Experiment 1, we registered the ERPs elicited by dissonant clusters placed either at the middle or the ending position of chord cadences. In Experiment 2, we presented to the listeners with a high proportion of cadences ending in a dissonant chord. In both experiments, we compared the ERPs of musicians and non-musicians. Dissonant clusters elicited distinctive neural responses (an early negativity, the P3 and the N5). While the EN was not affected by syntactic rules, the P3a and P3b were larger for dissonant closures than for middle dissonant chords. Interestingly, these components were larger in musicians than in non-musicians, while the N5 was the opposite. Finally, the predictability of dissonant closures in our experiment did not modulate any of the ERPs. Our study suggests that, at early time windows, dissonance is processed based on acoustic deviance independently of syntactic rules. However, at longer latencies, listeners may be able to engage integration mechanisms and further processes of attentional and structural analysis dependent on musical hierarchies, which are enhanced in musicians.
Gonococcal invasion into epithelial cells depends on both cell polarity and ezrin

Published: December 2021

Neisseria gonorrhoeae (GC) establishes infection in women from the cervix, lined with heterogeneous epithelial cells from non-polarized stratified at the ectocervix to polarized columnar at the endocervix. We have previously shown that GC differentially colonize and transmigrate across the ecto and endocervical epithelia. However, whether and how GC invade into heterogeneous cervical epithelial cells is unknown. This study examined GC entry of epithelial cells with various properties, using human cervical tissue explant and non-polarized/polarized epithelial cell line models. While adhering to non-polarized and polarized epithelial cells at similar levels, GC invaded into non-polarized more efficiently than polarized epithelial cells. The enhanced GC invasion in non-polarized epithelial cells was associated with increased ezrin phosphorylation, F-actin and ezrin recruitment to GC adherent sites, and the elongation of GC-associated microvilli. Inhibition of ezrin phosphorylation inhibited F-actin and ezrin recruitment and microvilli elongation, leading to a reduction in GC invasion. The reduced GC invasion in polarized epithelial cells was associated with non-muscle myosin II-mediated F-actin disassembly and microvilli denudation at GC adherence sites. Surprisingly, intraepithelial GC were only detected inside epithelial cells shedding from the cervix by immunofluorescence microscopy, but not significantly in the ectocervical and the endocervical regions. We observed similar ezrin and F-actin recruitment in exfoliated cervical epithelial cells but not in those that remained in the ectocervical epithelium, as the luminal layer of ectocervical epithelial cells expressed ten-fold lower levels of ezrin than those beneath. However, GC inoculation induced F-actin reduction and myosin recruitment in the endocervix, similar to what was seen in polarized epithelial cells. Collectively, our results suggest that while GC invade non-polarized epithelial cells through ezrin-driven microvilli elongation, the apical polarization of ezrin and F-actin inhibits GC entry into polarized epithelial cells.

Published: December 2021

Introduction: Resilience is the ability to adapt or recover after adverse situations.This study aimed to adapt and investigate evidence of the validity of the Brief Resilience Scale (BRS) for the Brazilian context. Method: The total sample comprised 1,937 people who participated in the study and the validity analysis was carried out with 1,480 people between 18 and 78 years of age. It was carried out using translation, back-translation, descriptive analysis, reliability analysis, confirmatory factor analysis, Item Response Theory, the ROC curve and BRS correlation with the Connor-Davidson Resilience Scale - 10-item version (CD-RISC-10), the Social Support Perception Scale, the Patient Health Questionnaire - 2-item version (PHQ-2), and sociodemographic data. Results: The results showed the adequacy of the Brazilian version of the BRS (BRS-BR), alpha of 0.80, omega = 0.81, one factor, good information capacity of the items (except for item 5) and correlation with the CD-RISC-10 (rho = 0.64), PHQ-2 (rho = - 0.38)and Social Support (rho = 0.14). There was also a correlation with sex (rho = 0.11), age (rho = 0.13), marital status (rho = 0.15) and schooling (rho = 0.15). The ROC curve shows a cutoff point at 10 points for low resilience and 21 points for high resilience. Conclusions: The investigation of the psychometric characteristics of the BRS-BR showed that the instrument can be useful for the evaluation of resilience in the Brazilian context.
El carácter reflexivo de la lingüística
Authors: Montemayor-Borsinger Ann
Published: December 2021

La Lingüística Sistémico Funcional (LSF), por considerar el lenguaje como una semiótica social, se basa en una teoría gramatical socio-semántica y discursiva. Asimismo, a lo largo del desarrollo de la LSF, Halliday y sus seguidores han rescatado la rica y necesaria ambigüedad del lenguaje, que le permite adaptarse a nuevas realidades. Por ello, nunca encubrieron las ambigüedades que existen en el metalenguaje que usa la lingüística para describir su objeto de estudio. Elsa Ghio, como gran traductora y promotora de la obra de Halliday al español, supo difundirla teniendo en cuenta este carácter reflexivo de la lingüística. Aquí nos detenemos en tres casos, uno de recodificación de términos del inglés al español, las nociones de Mode y Mood, otro de distintas representaciones para nociones gramaticales afines, las de metáfora gramatical experiencial y de nominalización, y un tercer caso de una misma representación para nociones gramaticales un tanto distintas, la de Tema.

This research explores the injury risks of occupants in four-door type of pick-up truck using experimental based collision with Hybrid III dummy for occupant injury indicators. The full-sized crash laboratory was developed to conduct full frontal impact based on standard regulation. To verify performance of full-sized crash laboratory and vehicle deceleration, low and high speed tests were conducted at the same vehicle. The Hybrid III dummy with head and chest sensors was used at the rear outboard seat during high speed test. Consequently, the deflection and thoracic viscous criteria, which represent the chest injuries, are up to 93 mm and 3.96 m/s, respectively, high beyond the standard requirement. Moreover, the most important finding of this research is that the four-door pickup truck is subjected to the 2nd impact up to 116.51 G at dummy head with higher resultant acceleration than the 1st impact (65.62 G) due to the limited space behind the rear headrest and thinner backrest of rear seat. This research also investigates the post-crash results to illustrate the suggestive idea for improving crashworthiness of future design resulting in mitigation of occupant injuries.

Authors: Luiz Caio Cesar Santos Patron , Bachesk Andressa Bolognesi , Iwaki Filho Liogi
Published: December 2021

Os sialolitos são estruturas calcificadas que se desenvolvem dentro dos ductos salivares. A hipótese mais aceita é da deposição de sais de cálcio ao redor de um foco de detritos na luz do ducto. A sialolitíase não tem predileção por raça e é mais comum em adultos de meia idade do sexo masculino, sendo a glândula submandibular a mais acometida. O diagnóstico é realizado por meio de exame clínico e de imagem; já o tratamento depende do tamanho e da localização do sialolito, podendo variar de estimulação salivar até sua remoção cirúrgica, com ou sem a glândula envolvida. Sendo assim, alguns relatos na literatura reportam a importância do reparo ductal, evitando complicações como fístula, estenose e fibrose. Desse modo, o presente relato apresenta um caso clínico bem-sucedido da excisão cirúrgica por acesso intrabucal de sialolito no ducto de Wharton, utilizando um cateter em PVC, que foi instalado e suturado à mucosa. Essa conduta resultou na comunicação da luz do ducto com o meio externo, mantendo sua continuidade, evitando seu colabamento e, consequentemente, promovendo a formação de um novo óstio ductal. Conclui-se que a presente técnica, trouxe um pós-operatório confortável, com remissão de sintomatologia e restauração da função glandular.

Published: December 2021

The paper discuss the problem of lusophony as a poscolonial neoimperial Portuguese ideology. The author claims that the lusophonic mythology, that is currently being created, is ingrained in the tradition of salazarist propaganda. Also the frequent mentions of lusotropicalism in the context of the modern lusophony is observed especially in the case of enunciations of the Portuguese dignitaries of whom Mario Soares is the most proeminent. The conclusion is that the idea of lusophony may resemble lusotropicalism in many aspects, especially if we take into account the Portuguese point of view. Also the approach towards the idea of lusophony of the Portuguese speaking African countries and Brasil is shortly discussed.
Ser brasileiro na Polónia. Integração e identidade durante migração
Authors: Gawenda Dominika
Published: December 2021

This article attempts to look at migration from an anthropological perspective, especially at the issues of integration and the changes seen in the identity of migrants. Motivation and readiness for change, along with the existing stereotypes and personal experiences of a migrant, constitute successful adaptation in a new place of residence. One of the most important elements of integration in a new society is the knowledge of this group’s language, it facilitates entering the community and is very important in terms of the reproduction of one’s identity in the new place of residence. The recreation of one’s identity is necessary, because a migrant is placed in a completely new reality in which his / her previous social role and status are different. The creation of identity happens in between the two concepts of familiarity and foreignness.

Características da variante moçambicana da língua portuguesa com base na análise morfossintática dos diálogos presentes nos romances e contos de Mia Couto
Authors: Mikołajczak Sylwia
Published: December 2021

Portuguese is a native language of only a handful of people in Mozambique. However, it successfully plays the role of a common language of communication in the field of politics and economics. At the same time, it is a determinant of social status and, in the world of literature, it gives one the opportunity to break through to the readers around the Globe. Portuguese in Mozambique presents many differences from the European standard, and the specific characteristics of this variant can be found in the texts of Mia Couto. The purpose of this article is to present the differences between the variant of Mozambique and the European model of Portuguese, mainly in the field of morphosyntax, observed in the texts of Mia Couto. The marked differences can be seen, among others, in the use of prepositions, order of pronominal elements, in the structure of periphrastic and passive constructions, and the selection of verbal arguments. The features are highly repetitive, but at the same time, they occur quite irregularly, together with the structures accepted by the standard. It is, therefore, difficult to speak of a systematic language variant, but surely it is on its way to be established.

Impact of policies, strategies and agricultural institutions on food security and poverty status of vegetable farmers along the blue nile banks, Gezira State, Sudan (2017)
Authors: Bushara Mohamed O. A.
Published: December 2021

Having clear picture on food security status and its major determinants helps policy makers and planners to introduce new policies that enhance food security. The study was aimed to evaluate the impact of policies, strategies and institution on food security and poverty status of the vegetables farmers in Gezira State with reference to the Blue Nile farmers. To achieve these objectives stratified random sampling technique was used to select the respondents from five localities lays along Blue Nile, so 150 farming households were interviewed. Food security Policy and strategy were collected by the mean of questionnaire targeting key line institutions. Poverty indices were calculated using expenditure as welfare indicator,Gini coefficient was applied. The results showed that the majority 75% of the respondents were above expenditure poverty line (7196)SDG. Moreover, the results showed that the poverty gap index was equal to five percent. Kamlin, Medani, East Gezira reported the higher expenditure distance from the poverty line (6 percent). The severity of poverty in the state is estimated to be two percent, likewise the severity of poverty in East Gezira was found to have a higher percentage (three percent). According to Gini coefficient the income distribution estimated at 0.46 while that for expenditure distribution is estimated at 0.31, these results showed a higher degree of inequality. The results showed that the poorest 20% of the population earned 0.06% of the total income while the richest 20% earned 45% of the total income. About 50.7% from the respondents use borrowing from others as one of their coping strategies.  About 78%of policy makers said that there was organized team from all institutions dealing with food security and nutrition issue, all policy makers in the state said there was strategy concerning the food security and nutrition issues. The study recommended that the cash transfer needed to lift the poor out of poverty that each poor person needs five percent of the value of the poverty line.

Authors: Hamid Abdelsalam Adam , Amsami Maigana , Ibrahim Siddiq Balal
Published: December 2021

The purpose of this study was to examine whether customer gratitude mediates the association between ethical corporate social responsibility and customer loyalty. A cross-sectional survey was adopted. A total of 430 individual customers of retail banks located in some selected towns in north-east region of Nigeria were selected using convenience sampling. Structured questionnaires were used to collect. Descriptive statistics and partial least square structural equation modeling were used in data analysis. Finding showed that ethical corporate social responsibility positively and significantly affected customer loyalty. Also, a positive and significant effect of ethical corporate social responsibility on customer gratitude was observed. Furthermore, it was observed that customer gratitude and customer loyalty are positively associated. Also, customer gratitude mediated between ethical corporate social responsibility and customer loyalty. This study concluded that customer gratitude mediated the influence of ethical corporate social responsibility on customer loyalty. The finding of this study will help managers of Nigerian retail banks to develop ethical corporate social practices which strongly create feelings of gratitude among their banks’ customers in order to take advantage of customers’ gratitude, and eventually cultivate customers’ loyalty.
Gamma-convergence of Gaussian fractional perimeter
Authors: Carbotti Alessandro , Cito Simone , La Manna Domenico Angelo , Pallara Diego
Published: December 2021

We prove the Γ-convergence of the renormalised Gaussian fractionals-perimeter to the Gaussian perimeter ass→1-{s\to 1^{-}}. Our definition of fractional perimeter comes from that of the fractional powers of Ornstein–Uhlenbeck operator given via Bochner subordination formula. As a typical feature of the Gaussian setting, the constant appearing in front of the Γ-limit does not depend on the dimension.

Investigating cognitive factors and diagnostic error in a presentation of complicated multisystem disease
Authors: Thompson Ben , Madan Christopher R. , Patel Rakesh
Published: December 2021

Objectives

To use a case review approach for investigating the types of cognitive error identifiable following a complicated patient admission with a multisystem disorder in an acute care setting where diagnosis was difficult and delayed.

Methods

A case notes review was undertaken to explore the cognitive factors associated with diagnostic error in the case of an 18-year-old male presenting acutely unwell with myalgia, anorexia and vomiting. Each clinical interaction was analysed and identified cognitive factors were categorised using a framework developed by Graber et al.

Results

Cognitive factors resulting in diagnostic errors most frequently occurred within the first five days of hospital admission. The most common were premature closure; failure to order or follow up an appropriate test; over-reliance on someone else’s findings or opinion; over-estimating or underestimating usefulness or salience of a finding, and; ineffective, incomplete or faulty history and physical examination. Cognitive factors were particularly frequent around transitions of care and patient transfers from one clinical area to another. The presence of senior staff did not necessarily mitigate against diagnostic error from cognitive factors demonstrated by junior staff or diagnostic errors made out-of-hours.

Conclusions

Cognitive factors are a significant cause of diagnostic error within the first five days after admission, especially around transitions of care between different clinical settings and providers. Medical education interventions need to ensure clinical reasoning training supports individuals and teams to develop effective strategies for mitigating cognitive factors when faced with uncertainty over complex patients presenting with non-specific symptoms in order to reduce diagnostic error.
Wie die Finanzpolitik den Stopp des Klimawandels unterstützen kann – ein Interview
Authors: Giegold Sven
Published: December 2021

Sven Giegold, Sprecher der deutschen Grünen im Europaparlament und Obmann der grünen Fraktion im Ausschuss für Wirtschafts- und Finanzpolitik, erläutert in einem Interview die Rolle des Finanzmarktes für einen ambitionierten Klimaschutz. Dabei weist er auf die Bedeutung einer sozialen und solidarischen Ökonomie – dazu zählen Sozialwirtschaft, social entrepreneurs oder neue Genossenschaften –, einer risikosensiblen Neuaufstellung der Finanzmarktstrategien vor dem Hintergrund der Klimakrise und auch auf staatliche Regulierungsoptionen des Finanzmarktes hin. Weitere Themen sind der Green Deal der Europäischen Kommission, die Entwicklung weltweiter Unternehmensbesteuerung, sustainable Finance und die Kritik an einer „sakralisierten“ schwarzen Null, Kryptowährung sowie Finanztransaktionssteuer und Mikrokredite. Für die vorgestellte Agenda braucht es Partner in der Zivilgesellschaft.
Gelehrter Habitus und eremitische Lebensform. Eine Sozialgeschichte der Einsamkeit in der Ära Peter Abaelards
Authors: Rexroth Frank
Published: December 2021

Der Habitus vormoderner Gelehrter ist stark von dem Erfordernis zur Konzentration und von selbst gewählter Abschottung von den Reizen der Umwelt geprägt. Im Gegensatz zu früheren Erklärungsversuchen präsentiert dieser Aufsatz die These, dass nicht erst der Renaissance-Humanismus, sondern schon das Jahrhundert von ca. 1050 bis ca. 1150 hierfür eine prägende Rolle gespielt hat. Die privaten, freien „scholae“, die in jener Phase aufblühen, sind eingebettet in eine zeittypische Kultur der Einsamkeit und einen Kult des Eremitentums, an dem sich zahlreiche Magister und Scholaren nachweislich beteiligt haben. Der Aufsatz untersucht die Verbindungen, die zwischen den „scholae“ der frühen Scholastik und den Siedlungen gesellschaftlicher Aussteiger und Eremiten bestehen.
Wasserverbrauch privater Haushalte in Deutschland: Eine empirische Mikroanalyse
Authors: Frondel Manuel , Niehues Delia A. , Sommer Stephan
Published: December 2021

Germany is a rather water-rich country. Nevertheless, climatic changes might make it necessary to use water resources carefully in the future, especially in times of drought. Against this background, this paper estimates the price elasticity of household water consumption, differentiating between households that have a rough knowledge of water prices and households that do not. Based on about 1,100 observations for households living in single-family houses and using the sum of cubic meter prices for water and wastewater as price measure, we find a moderate but statistically significantly non-zero price elasticity of -0.102. Households that have knowledge of water prices tend to exhibit a higher elasticity, while households without price knowledge do not show a statistically significant response in their water consumption. Prices can thus only be used to a limited extent as a means of controlling water consumption.

Published: December 2021

Background: We herein report our experience of optimized utilization of tocilizumab for patients with coronavirus disease 2019 (COVID-19) in a limited-resource tertiary care hospital.

Methods: This single-center, single-arm, open-label, interventional study was conducted to determine the effect of tocilizumab on the mortality of patients with COVID-19.

Results: Fifty-nine patients were administered tocilizumab. Patients who received invasive respiratory support were identified to have a higher risk of mortality than those who received oxygen support.

Conclusion: Our study showed that the maximum benefit of tocilizumab was observed as a prophylactic treatment of cytokine syndrome in patients with COVID-19, particularly those with moderate to severe symptoms who are not receiving invasive respiratory support.
