Authors: Gupta Shishir , Dutta Rachaita , Das Soumik 
Published: October 2022

Purpose
This paper aims to study photothermal excitation process in an initially stressed semi-infinite double porous thermoelastic semiconductor with voids subjected to Eringen’s nonlocal elasticity theory under the fractional order triple-phase-lag thermoelasticity theory. The considered substrate is governed by the mechanical and thermal loads at the free surface.

Design/methodology/approach
The normal mode technique is used to carry out the investigation of photothermal transportation. By virtue of the MATHEMATICA software, each distribution is exhibited graphically.

Findings
The expressions of the displacements, temperature, volume fractions of both kinds of voids, carrier density and stresses are determined analytically. With the help of the numerical data for silicon (Si) material, graphical implementations are presented on the basis of initial stress, fractional order, nonlocality and thermoelectric coupling parameters.

Originality/value
The present study fabricates the association of Eringen’s nonlocal theory and the stress analysis in a semiconducting double porous thermoelastic material with voids, which significantly implies the originality of the conducted work.
Investor attention and the COVID-19 concept stocks in China's stock market
Authors: Liu Zhe , Huang Chong , Yang Benshuo 
Published: October 2022

PurposeThis paper investigates the impact of investor attention on the COVID-19 concept stocks in China's stock market from the perspectives of the macroeconomy, the stock market and the COVID-19 pandemic.Design/methodology/approachOn the basis of controlling the time effects and individual fixed effects, this paper studies the impact of investor attention on the COVID-19 concept stocks in China's stock market through a set of fixed effect panel data models. Among them, investor attention focuses on macroeconomy, stock market and the COVID-19 pandemic, respectively, while stock indicators cover return, volatility and turnover. In addition, this paper also examines the heterogeneity influence of investor attention on the COVID-19 concept stocks from the perspective of time and stock classification.FindingsFindings indicate that the attention to macroeconomy does not have a statistically significant effect on the return, unlike the attention to stock market and COVID-19 incident. Three types of investor attention have significant positive effects on the volatility and turnover rate. During the outbreak of the domestic epidemic, the impact of investor attention was significantly higher than that during the outbreak of the epidemic overseas. A finer-grained analysis shows that the attention to stock market has significantly increased the return of preventive type and treatment type stocks, while diagnostic-related stocks have been most affected by the attention to COVID-19 incident.Research limitations/implicationsThe major limitation of this work is the construction of investor attention. Although Baidu index is widely used, investor attention can be assessed more accurately based on more unstructured data. In addition, the effect of the COVID-19 can also be investigated in a longer time domain. Further research can be combined with the dynamics of the COVID-19 pandemic to more comprehensively evaluate its impact on the stock market.Originality/valueThe research proves that investor attention plays an important role in stock pricing and provides empirical evidence on the behavioral foundations of the conceptual sector of the stock market under uncertainty. It also has practical implications for regulators and investors interested in conducting accurate asset allocation and risk assessment.
Private open space as a reflection of culture: the example of traditional courtyard houses in Nigeria
Authors: Adebara Temitope Muyiwa 
Published: October 2022

PurposeThe courtyard form of the traditional African house responds to people's culture and traditions. Nevertheless, in the era of globalization, the private open space (POS) is fast disappearing in African homes due to neglect and lack of awareness of its value. This study, thus, aims to explore how culture relates to open space design in traditional houses of three major ethnic groups (Hausa-Fulani, Yoruba and Igbo) in Nigeria. This is with a view to encouraging planners and designers to create open spaces in housing developments according to people's cultural values and needs.Design/methodology/approachThis study is based on qualitative and quantitative research approaches involving a literature review, focus group discussions and a questionnaire survey. The quantitative survey was designed based on the literature review of the concept of culture and the use of space in traditional courtyard houses. Focus group discussions were conducted to identify the specific cultural components that dictated the use of the courtyard as a POS in the Nigerian context. Subsequently, a questionnaire survey was carried out to determine the importance of each cultural component in the outdoor sociospatial design. Through systematic sampling, one of every five traditional houses in the study area was selected to determine where respondents were surveyed.FindingsThe results reveal that the cultural components that influenced the design and use of the open space were gender and privacy, family and social relations, religious practice and belief, and status and lifestyle. However, the importance attached to each of the cultural components varied from one culture to another in Nigeria. The findings also showed that the open space is used for a variety of purposes, such as ancestral worship, family gatherings and reunions, small-scale ceremonies, and leisure activities.Research limitations/implicationsThis study offers professional planners and designers helpful insights to protect culture in housing development and improve daily living in residential environments.Originality/valueBased on Amos Rapoport's theoretical framework, this study dismantles the concept of “culture” into different components and examines how they affect outdoor sociospatial design in a developing country. The study also provides researchers with ideas and inspiration to study the culture of POSs in traditional housing.
Combinative distance-based assessment (CODAS) approach of multi-criteria decision-making for grading of Tossa jute fibres
Authors: Mitra Ashis 
Published: October 2022

Purpose
The present study aims to demonstrate the application of newly developed combinative distance-based assessment (CODAS) approach for grading and selection of Tossa jute fibres, which possesses some unique features uncommon to other variants of multi-criteria decision-making (MCDM) method.

Design/methodology/approach
The CODAS method was used in this study to rank/grade ten candidate lots of Tossa fibres on the basis of six apposite jute fibre properties, namely, fibre defect, root content, fineness, strength, colour and density. These six fibre properties were considered as the six decision criteria, here, and they were assigned weights as determined previously by an earlier researcher using analytic hierarchy process. The grading of jute fibres was done based on a comprehensive single index known as the assessment scores (Hi), in descending order of magnitude.

Findings
Among the 10 Tossa jute lots, T2 was ranked 1 (top grade) because of the highest assessment score of 6.887, followed by T1 with Rank 2 (assessment score 1.830). Because of the least assessment score of −2.795, the candidate lot T4 was considered as the worst, and hence ranked 10. The overall ranking pattern given by the CODAS method was similar to the TOPSIS approach done by Ghosh and Das (2013). This study was supported by various sensitivity analyses to judge the efficacy of the present approach. No occurrence of rank reversal during the sensitivity analyses obviously corroborates the robustness and stability of the CODAS method.

Practical implications
Jute pricing is fixed solely by the quality for which grading of fibre is prerequisite. The traditional “Hand and Eye” method or Bureau of Indian Standards (BIS) system for jute grading is basically subjective assessment and need domain expertise. MCDM is reported as the most viable solution which gives due importance to the fibre parameters while grading the fibres based on a single index. The present study demonstrates the maiden application of CODAS to address the fibre grading problems for jute industries. This approach can also be extended to solve other decision problems of textile industry, in general.

Originality/value
CODAS is a recently developed exponent of MCDM. Uniqueness of the present study lies in the fact that this is the first ever application of CODAS in the domain of textile industry, in general, and jute industry, in particular. CODAS approach is very simple involving a few simple mathematical equations yet a potent tool of decision-making. This method possesses some features uncommon in other variants of MCDM. Moreover, the efficacy of CODAS method is investigated through various sensitivity analyses, which has been ignored in the earlier approaches.
Should I buy a Caribbean condo during a pandemic? Valuing a real estate investment using cash flows
Authors: Gattis Louis 
Published: October 2022

Research methodology
This case was a real-life situation faced by the author. Names were changed, so students would not know that the author was the protagonist. The case had been developed over several years as a capstone to the capital budgeting section of an MBA finance course and an advanced undergraduate course.

Case overview/synopsis
Trey and Lauren Gallo were considering the purchase of a vacation condo that also generated rental income. The current owners were willing to sell at a lowball offer of $605,000 as the pandemic entered its 13th month. The Gallos felt they needed to act fast to get this deal. However, the risks were extraordinary, as the pandemic had reduced rental income by 50% and borders had just recently closed. The case provides all data needed to compute rental revenues, capital expenditure, operational expenditures and financing costs. Students are expected to compute the NPV and IRR of free cashflows. Students will compute and evaluate the cost of capital using the condo’s projected debt structure, a choice of several proxy betas and a project risk premium. The case also uses extensive sensitivity analysis. This case differs from corporate capital budgeting problems because it evaluates both levered and unlevered cashflows, and the cashflows include savings from personal use. The case has been successfully used in MBA finance courses and advanced undergraduate finance courses. The case can be used as a capstone case for capital budgeting or a comprehensive exam in undergraduate, MBA and executive programs. The case questions can also be spread throughout a course to cover the topics of financial statement forecasting, free cash flows, capital budgeting, cost of capital and sensitivity analysis.

Complexity academic level
Earlier versions of this case have been used in an advanced undergraduate corporate finance course and MBA finance courses. The case is generally used as a capstone to the material on capital budgeting. Students should have already covered material on financial statements, loan cashflows, levered and unlevered cashflows, CAPM, proxy betas, weighted average cost of capital, NPV and IRR. This case is also appropriate for courses in real estate finance and personal finance.
Reactive arthritis and subacute infective endocarditis caused by Streptococcus gordonii infection: A case report
Authors: Yan Li‐Fang , Zhang Jie , Zhang Zhen 
Published: October 2022

AbstractStreptococcus gordonii (S. gordonii) belongs to the alpha‐hemolytic Streptococcus group. It is a symbiotic bacterium found in the human oral mucosa which is present in large quantities on the surface of the teeth. It is generally considered nonpathogenic or weakly pathogenic and is known to cause subacute endocarditis; however, there are few reports of reactive arthritis (ReA) caused by S. gordonii. Herein, we report a case of ReA complicated by subacute infective endocarditis caused by S. gordonii and explore the possible pathogenic mechanism of ReA caused by S. gordonii.
Ligelizumab impairs IgE‐binding to plasmacytoid dendritic cells more potently than omalizumab and restores IFN‐α production and FOXP3+ Treg generation

Published: October 2022

AbstractBackgroundLigelizumab is an anti‐IgE monoclonal antibody binding IgE with higher affinity than omalizumab that is under clinical investigation for several IgE‐mediated diseases. We previously showed that omalizumab removes IgE bound to FcεRI on plasmacytoid dendritic cells (pDCs) and restores their ability to produce IFN‐α and regulatory T cells (Tregs). The aim of this work is to investigate the capacity of ligelizumab to regulate functional properties of pDCs in comparison with omalizumab.MethodspDCs were isolated from atopic donors and IgE was detached from FcεRI on pDCs with designed ankyrin repeat protein (DARPin) bi53‐79. pDCs were resensitized with IgE alone or in the presence of ligelizumab or omalizumab prior to IgE‐FcεRI crosslinking and Toll‐like receptor 9 (TLR9) stimulation. Flow cytometry, ELISA, coculture experiments and intranuclear staining were performed to determine cytokine production and Treg generation. An antigen‐specific model of resensitization and IgE‐crosslinking was also performed.ResultsThe levels of serum total free IgE show a non‐linear positive correlation with the frequency of IgE+ pDCs displaying IgE bound to FcεRI within the 43 individual donors included in the study. Ligelizumab displays stronger capacity than omalizumab to block the binding of free IgE to FcεRI on human pDCs, resulting in a greater restoration of TLR9‐L‐induced IFN‐α production. Ligelizumab also restores the ability of pDCs to generate FOXP3+ Tregs as previously reported for omalizumab.ConclusionsThe uncovered novel molecular mechanisms of ligelizumab to regulate functional properties of pDCs from atopic donors might have important clinical implications for anti‐IgE treatments in different IgE‐mediated diseases.

Authors: Paterson E. , Paterson N. A. B. , Ferris L. J. 
Published: October 2022

SummaryThe COVID‐19 pandemic has imposed substantial burdens on clinicians and there is a need to better understand the impact on mental health and well‐being. This scoping review investigates the prevalence of mental health concerns in anaesthetists, risk and protective factors for mental well‐being, and anaesthetists' pandemic‐related concerns and support. We searched online databases for articles published between January 2020 and May 2022, using search terms related to: anaesthesia; burnout, well‐being, mental health or stress; and COVID‐19. We identified 20 articles comprising 19 different populations of anaesthetists (n = 8680) from 14 countries. Studies identified the prevalence of the following condition in anaesthetists: burnout (14–59%); stress (50–71%); anxiety (11–74%); depression (12–67%); post‐traumatic stress (17–25%); psychological distress (52%); and insomnia (17–61%). Significant risk factors for poorer mental health included: direct COVID‐19‐related issues (fear of self and family exposure to infection; requirement for quarantine); practitioner health factors (insomnia; comorbidities); psychosocial factors (loneliness; isolation; perceived lack of support at home and work); demographic factors (female gender; non‐white ethnicity; LGBTQIA+); and workplace factors (redeployment outside area of clinical practice; increased work effort; personal protective equipment shortages). Protective factors identified included: job satisfaction; perceived organisational justice; older age; and male sex. Anaesthetists' self‐reported concerns related to: personal protective equipment; resource allocation; fear of infection; fear of financial loss; increased workload; and effective communication of protocols for patient treatment. Support from family, colleagues and hospital management was identified as an important coping mechanism. Findings from this review may support the design of interventions to enhance anaesthetists' psychological health during pandemic conditions and beyond. Future research should include consistent psychological outcome measures and rigorous experimental design beyond cross‐sectional studies.

Published: October 2022

AbstractBackgroundThe acrylonitrile‐co‐methallyl sulfonate surface‐treated (AN69ST) membrane has cytokine adsorption capacity and is used for treating sepsis. This study aimed to compare the effects of continuous renal replacement therapy (CRRT) using the AN69ST membrane with those of CRRT using other membranes for patients with pneumonia‐associated sepsis.MethodsThis retrospective, propensity score‐matched, cohort study was based on a nationwide Japanese inpatient database. We included data from adults hospitalized with a primary diagnosis of pneumonia, who received CRRT using either the AN69ST membrane or another membrane within 2 days of admission, and who were discharged from the hospitals between September 2014, and March 2017. Propensity score matching was used to compare in‐hospital mortality between the two groups.ResultsEligible patients (N = 2393) were categorized into an AN69ST group (N = 631) and a non‐AN69ST group (N = 1762). The overall in‐hospital mortality rate was 38.9%. Among the 545 propensity‐matched patient pairs, the in‐hospital mortality rate was significantly lower in the AN69ST group than in the non‐AN69ST group (35.8 vs. 41.8%, p = 0.046).ConclusionsAmong patients with pneumonia‐associated sepsis treated with CRRT, CRRT with the AN69ST membrane was associated with a significantly lower in‐hospital mortality than CRRT with standard membranes.

Published: October 2022

AbstractBackgroundPulsatile extracorporeal circulation (ECC) may improve perfusion of critical organs during cardiac surgery. This study analyzed the influence of the components of a minimal invasive ECC (MiECC) on the transfer of pulsatile energy into the pseudo‐patient of a mock circulation.MethodsAn aortic model with human‐like geometry and compliance was perfused by a diagonal pump. Surplus hemodynamic energy (SHE) was determined from flow and pressure data. Five adult‐size oxygenator models and three sizes of cannulas were compared. Pulsatile pump settings were optimized, and parallel dual‐pump configurations were evaluated.ResultsOxygenator models showed up to twofold differences in pressure gradients and influenced SHE at flow rates up to 2.0 L min−1. Adjustments of frequency, systole duration, and rotational speed gain significantly improved SHE compared with empirical settings, with SHE above 21% of mean arterial pressure at flow rates of 1.0 L min−1 to 1.5 L min−1 and SHE above 5% at 3.5 L min−1. Small diameter cannula (15 Fr) limited SHE compared with larger cannula (21 Fr and 23 Fr). Two diagonal pumps did not provide higher SHE than a single pump, but permitted additional control over pulse pressure and SHE by varying the total fraction of pulsatile flow and the fraction of flow bypassing the oxygenator.ConclusionsProper selection of components and optimizations of pump settings significantly improved pulse pressure and SHE of pulsatile MiECC. Surplus hemodynamic energy depended on flow rate with a maximum at 1.0 L min−1–1.5 L min−1. Pulsatile MiECC may specifically assist organ perfusion during phases of low flow.
Ror1 is expressed inducibly by Notch and hypoxia signaling and regulates stem cell‐like property of glioblastoma cells

Published: October 2022

AbstractRor1 plays a crucial role in cancer progression by regulating cell proliferation and migration. Ror1 is expressed abundantly in various types of cancer cells and cancer stem‐like cells. However, the molecular mechanisms regulating expression of Ror1 in these cells remain largely unknown. Ror1 and its putative ligand Wnt5a are expressed highly in malignant gliomas, especially in glioblastomas, and the extents of Ror1 expression are correlated positively with poorer prognosis in patients with gliomas. We show that Ror1 expression can be upregulated in glioblastoma cells under spheroid culture, but not adherent culture conditions. Notch and hypoxia signaling pathways have been shown to be activated in spheroid‐forming glioblastoma stem‐like cells (GSCs), and Ror1 expression in glioblastoma cells is indeed suppressed by inhibiting either Notch or hypoxia signaling. Meanwhile, either forced expression of the Notch intracellular domain (NICD) in or hypoxic culture of glioblastoma cells result in enhanced expression of Ror1 in the cells. Consistently, we show that both NICD and hypoxia‐inducible factor 1 alpha bind to upstream regions within the Ror1 gene more efficiently in GSCs under spheroid culture conditions. Furthermore, we provide evidence indicating that binding of Wnt5a to Ror1, upregulated by Notch and hypoxia signaling pathways in GSCs, might promote their spheroid‐forming ability. Collectively, these findings indicate for the first time that Notch and hypoxia signaling pathways can elicit a Wnt5a–Ror1 axis through transcriptional activation of Ror1 in glioblastoma cells, thereby promoting their stem cell‐like property.
