Authors: Deepa V. , Baber Hasnan , Shukla Balvinder , Sujatha R. , Khan Danish 
Published: September 2022

PurposeThe COVID-19 pandemic pushed organizations across the world to suddenly adopt work from home at a mass scale to maintain business continuity. This study aims to investigate the influence of lack of social interaction in work from the home arrangement on employee work effectiveness.Design/methodology/approachThe data were analysed using the partial least square (PLS) structural equation modelling (SEM) approach, a nonparametric method based on total variance, through SmartPLS software 3.0. The data were collected from 399 participants in India using the snowball sampling technique. The target populations were the people who were working from home due to the pandemic and by asking them to forward the survey link in their network.FindingsThe results suggest that social interaction has a significant positive impact on work effectiveness. However, this impact is not affected by the employee's perceived benefits of maintaining social distancing during the pandemic. The study also found that social interaction is important for both genders and found no significant difference in the relationship between social interaction and work from home effectiveness for male and female employees.Practical implicationsThis study will be useful for human resource practitioners and managers as they build strategies to adopt work from home as a regular practice even in non-pandemic situations.Originality/valueThis study is the first to examine the influence of lack of social interaction on the work from home effectiveness during the COVID-19 times. It examines the moderating role of the perceived benefits of maintaining social distancing and gender on the effect of lack of social interaction as a barrier to work from home effectiveness.

Published: September 2022

PurposeThere is strong excitement during Ponzi schemes and financial bubble periods. This emotion causes investors to turn to “unknown and new investment instruments”. This study, the factors that made “unknown and new investment instruments” preferable to “known and experienced investment instruments” were investigated.Design/methodology/approachIt was taken into account unconscious like phantasy, emotional like emotional intelligence, both affective and cognitive like financial literacy and subjective beliefs like trust and overconfidence. In addition, risk preferences were measured with four different risk variables. In this context, data were collected by online survey method between November 2020 and May 2021 with convenience sampling. First, the data were collected from 832 participants in the pilot study. Additional data were also collected using convenience sampling and online surveys, and a total of 1,692 participants were obtained. Data were analyzed using Statistical Package for the Social Sciences (SPSS) 25 and AMOS 24.FindingsAs a result of the analyses made, the variables that lead investors to choose “unknown and new investment instruments” were determined as risky investment intention, phantasy, risk taking/risk avoidance, confidence, risk tolerance and subjective financial literacy. Trust and risk perception have a very weak effect on preferences. However, no effect of emotional intelligence and objective financial literacy was detected. In addition, a moderately positive and significant relationship was found between objective and subjective financial literacy. Subjective financial literacy was found to have a strong and significant relationship with emotional intelligence, confidence, trust, risky investment intention and phantasy.Originality/valueThis study investigates the factors underlying individuals' investment preferences from a broad perspective. We think that this study is unique in this structure and wide variables. We believe that the findings obtained in this manner are unique to both academics and practitioners. We also believe that the findings of the study will make an important contribution to understanding participation behavior in various Ponzi schemes and financial bubbles.

PurposeSustainable development of entrepreneurship could be comprehensively analyzed using a simulation model for entrepreneurship ecosystem based on the system dynamics approach. Thus, a complete analysis of the entrepreneurship ecosystem is of high importance. However, an effective analysis of entrepreneurship ecosystem involves many challenges, such as the presence of several factors which interact with each other in various ways with different complex effects in time. Therefore, the approach used in this study is employing analysis of entrepreneurship ecosystems in sports industry using analysis of dynamic systems.Design/methodology/approachSeveral applied issues such as entrepreneurship opportunities, infrastructures, market opportunities and entrepreneurship space in the borders of the dynamic model developed based on the literature and experts' opinion. Finally, a set of strategies based on experts' opinion are ranked with the objective of improvement of evaluation measures using network analysis decision-making approach and fuzzy TOPSIS.FindingsThe results obtained indicate the important role of sports entrepreneurship opportunities, sports tourism, market opportunities, entrepreneurship infrastructures and entrepreneurship-oriented environment in the development of sports entrepreneurship infrastructure in Iran. The credibility and efficiency of the proposed model for analysis of sports entrepreneurship have been ultimately shown.Originality/valueA holistic approach is proposed based on the hybrid system dynamics approach and fuzzy decision-making method to analyses sports entrepreneurship ecosystem.
The effect of student self-efficacy on learning outcomes in a business simulation mobile game: a quasi-experimental study
Authors: Yang Qixing , Chen Quan , Wang Jingan , Ou Ruiqiu 
Published: September 2022

PurposeThis study has two objectives: to explore the factors that influence student self-efficacy regarding engagement and learning outcomes in a business simulation game course and to compare the difference between hierarchical and general teaching methods.Design/methodology/approachFrom September 2021 to May 2022, a questionnaire was administered to 126 students in a business simulation game course at the Zhongshan Institute, University of Electronic Science and Technology of China. Data were analyzed using nonparametric paired samples tests and linear regression.FindingsThe results showed that student self-efficacy, engagement and learning outcomes were significantly higher with the hierarchical teaching method than with the general teaching method. There were also differences in the factors that influenced self-efficacy regarding learning outcomes between the two teaching methods. With the general teaching method, student self-efficacy did not directly affect learning outcomes, but did so indirectly by mediating the effect of engagement. However, with the hierarchical teaching method, self-efficacy directly and significantly affected learning outcomes, in addition to indirectly affecting learning outcomes through student engagement.Research limitations/implicationsCompared with the control group experimental research method, the quasi-experimental research method can eliminate the influence of sample heterogeneity itself, but the state of the same sample may change at different times, which is not necessarily caused by the hierarchical teaching design.Practical implicationsBased on the results of this study, teachers can apply hierarchical teaching according to student ability levels when integrating business simulation games. The results of this study can inspire teachers to protect student self-confidence and make teaching objectives and specific requirements clear in the beginning of the course, and also provide an important practical suggestion for students on how to improve their course performance.Social implicationsThe research results can be extended to other courses. Teachers can improve students' self-efficacy through hierarchical teaching design, thus improving students' learning performance and also provide reference value for students to improve their learning performance.Originality/valueThis study built a model based on self-system model of motivational development (SSMMD) theory, comparing factors that affect student self-efficacy regarding learning outcomes under different teaching methods. The model enriches the literature on SSMMD theory as applied to business simulation game courses and adds to our understanding of hierarchical teaching methods in this field. The results provide a valuable reference for teachers that can improve teaching methods and learning outcomes.

Published: September 2022

PurposeTotal quality management is a valuable approach to continuously improve the quality of organizations; however, scholars debate its applicability to services, which require specific best practices that are different from those related to manufacturing. Moreover, digitization is pervading all kinds of services, but little has been written about total quality service practices in digital-based companies. For this purpose, the authors provide a holistic model of total quality service that reflects the peculiarities of such companies, guided by the question: how do total quality service practices change in digital-based service organizations?Design/methodology/approachThe authors conduct an illustrative case study on Healthware Group, a global integrated digital health organization, to evaluate theoretical assumptions about total quality service practices in the digital environment.FindingsThe findings allow to validate the model provided. In addition, the study enables them to observe the changes the authors are witnessing in service provision in the digital era and the consequent transformation of best practices. To be accurate, the authors cannot refer to a full transformation in digital-based companies but rather to the enrichment and extension of TQS practices. The best illustration of these conclusions has been summarized in a set of propositions corresponding to seven of the key levers of a TQS model.Originality/valueThe paper represents the first attempt to discuss the relationship between total quality service and digitalization, offering a set of propositions for academics and insights for practitioners. The model can be used as a tool to visualize the different levers that successful implementation of TQS in digital-based services companies can rely on.
SlyA regulates virulence gene expressions through activation of pchA regulatory gene in enterohemorrhagic Escherichia coli
Authors: Hamamura Riho , Yen Hilo , Tobe Toru 
Published: September 2022

AbstractSlyA is a DNA‐binding protein that alters the nucleoid complex composed of histone‐like nucleoid‐structuring protein (H‐NS) and activates gene expression. In enterohemorrhagic Escherichia coli (EHEC), the expression of virulence genes is repressed by H‐NS but is up‐regulated in response to environmental factors by releasing a nucleoid complex. This study examined the effect of slyA deletion mutation in EHEC and discovered that the production of the locus of enterocyte effacement (LEE)‐encoded EspB and Tir, as well as the cell adherence ability, was reduced in the mutant compared with the wild type. The promoter activity of the LEE1 operon, including the regulatory gene, ler, was reduced by slyA mutation, but tac promoter‐controlled expression of pchA, which is a regulatory gene of LEE1, abolished the effect. The promoter activity of pchA was down‐regulated by the slyA mutation. Furthermore, the coding region was required for its regulation and was bound to SlyA, which indicates the direct regulation of pchA by SlyA. However, the slyA mutation did not affect the butyrate‐induced increase in pchA promoter activity. Additionally, the pchA promoter activity was increased via induction of lrp, a regulatory gene for butyrate response, in the slyA mutant and, conversely, by introducing high copies of slyA into the lrp mutant. These results indicate that SlyA is a positive regulator of pchA and is independent of the Lrp regulatory system. SlyA may be involved in the virulence expression in EHEC, maintaining a certain level of expression in the absence of a butyrate response.
Mycotoxins in soybean‐based foods fermented with filamentous fungi: Occurrence and preventive strategies
Authors: Tian Fei , Woo So Young , Lee Sang Yoo , Park Su Been , Im Ju Hee , Chun Hyang Sook 
Published: September 2022

AbstractFermented soybean products are widely consumed worldwide, and their popularity is increasing. Filamentous fungi, such as Actinomucor, Aspergillus, Monascus, Mucor, Penicillium, Rhizopus, and Zymomonas, play critical roles in the fermentation processes of many soybean foods. However, besides producing essential enzymes for food fermentation, filamentous fungi can release undesirable or even toxic metabolites into the food. Mycotoxins are toxic secondary metabolites produced by certain filamentous fungi and may be detected during the food production process. Without effective prevention strategies, mycotoxin contamination in fermented soybean products poses a risk to human health. This review focused on the changes in mycotoxigenic fungal abundance and mycotoxin contamination at different stages during the production of soybean‐based fermented foods, as well as effective strategies for preventing mycotoxin contamination in such products. Data from relevant studies demonstrated a tendency of change in the genera of mycotoxigenic fungi and types of mycotoxins (aflatoxins, alternariol, alternariol monomethyl ether, deoxynivalenol, fumonisins, ochratoxin A, rhizoxins, T‐2 toxin, and zearalenone) present in the raw materials and the middle and final products. The applicability of traditional chemical and physical mitigation strategies and novel eco‐friendly biocontrol approaches to prevent mycotoxin contamination in soybean‐based fermented foods were discussed. The present review highlights the risks of mycotoxin contamination during the production of fermented soybean products and recommends promising strategies for eliminating mycotoxin contamination risk in soybean‐based fermented foods.

Published: September 2022

AbstractThe use of YouTube videos for educational purposes has been increasingly popular. The quality and accuracy of the information level of these videos should be checked by expert trainers. This study aims to evaluate the content, quality and functionality of YouTube videos on Histology and Embryology and to measure their educational usefulness. In the study, searches were performed using the keywords “Histology” and “Embryology” in the YouTube search tab. Quality and content were evaluated using the Video Power Index (VPI), modified DISCERN scale, JAMA and the Global Quality Scale (GQS). Videos were categorized by educational usefulness. SPSS software was used for statistical analysis. A statistically significant high correlation was observed between modified DISCERN scores and JAMA scores (r = 0.757, p < 0.001) and between modified DISCERN scores and GQS scores (r = 0.743, p < 0.001). A statistically significant high correlation was also determined between JAMA and GQS scores (r = 0.632, p < 0.001). GQS scores were weakly, negatively and significantly correlated with the number of comments (r = −0.302, p < 0.05) and dislikes (r = −0.325, p < 0.05). Based on GQS, the useful and non‐useful videos differed significantly in terms of views, likes, dislikes, comments counts and days since upload (p < 0.05). Modified DISCERN and JAMA scores also differed significantly between the useful and non‐useful videos (p < 0.001). Educational videos published for Histology and Embryology education on the internet will be more beneficial if they are prepared by expert educators from reliable information sources, by the current literature, and by scoring systems such as DISCERN, JAMA and GQS.

Published: September 2022

AbstractBackgroundThe unique anatomy of the male reproductive organ reflects its complex function from sperm maturation to their storage for months until emission. Since light microscopy in two dimensions (2d) cannot sufficiently demonstrate its complex morphology, a comprehensive visualization is required to identify pathologic alterations in its entire anatomical context.ObjectivesAim of this study was to use three‐dimensional (3d) light sheet fluorescence microscopy (LSFM) to visualize entire murine testes in 3d, label‐free and at subcellular resolution, and to assign local autofluorescence to testicular and deferent structures.Materials and methodsMurine testes were fixed with four different fixatives and subsequently cleared with benzoic acid/benzyl benzoate. Hereafter, complete murine testes were scanned with LSFM with different fluorescence filter sets and subsequently embedded in paraffin for further conventional planar histology.ResultsAutofluorescence signals of the murine reproductive organ allowed the unambiguous identification of the testicular anatomy from the seminiferous tubules to the vas deferens with their specific stratification independent of the used fixative. Blood vessels were visualized from the pampiniform plexus to the small capillaries of single tubules. Moreover, due to the specific intrinsic fluorescence properties of the efferent ducts and the epididymis, luminal caliber, the epithelial stratification and retronuclear cytoplasmic inclusions gave a unique insight into the interface of both morphological structures. Subsequent 2d histology confirmed the identified morphological structures.DiscussionLSFM analysis of the murine reproductive organ allows due to its intrinsic fluorescence a simple, label‐free 3d assessment of its entire duct morphology, the epithelial composition, and the associated blood supply in its anatomical relation.ConclusionLSFM provides the technical basis for comprehensive analyses of pathologically altered murine testes in its entirety by depicting specific autofluorescence. Thereby it facilitates mouse studies of testicular disease or their drug‐related alterations in more detail potentially for clinical translation assessing human testicular biopsies.

AbstractIntroductionMother‐to‐child transmission (MTCT) of the hepatitis B virus (HBV) is a serious public health challenge. Estimating HBV MTCT incidence by region under different prophylaxis regimens is critical to understanding the regional disease burden and prioritizing interventions. This study aimed to calculate HBV MTCT incidence under different prophylaxis regimens globally and regionally and identify the HBV DNA threshold for maternal peripartum antiviral prophylaxis.Material and methodsThis review was registered in advance in PROSPERO (CRD 42019120567). We searched PubMed, Embase, China National Knowledge Infrastructure, ClinicalTrials.gov, and Cochrane Library databases for studies on MTCT in pregnant women with chronic HBV infection from their inception until June 13, 2022. MTCT was defined as hepatitis B surface antigen (HBsAg) or HBV DNA seropositivity in infants aged 6–12 months. We calculated the pooled HBV MTCT incidence using the DerSimonian‐Laird random‐effects model.ResultsAmong 300 studies, 3402 of 63 293 infants had HBV due to MTCT. Without prophylaxis regimens, the pooled HBV MTCT incidence was 31.3%, ranging from 0.0% (95% confidence interval [CI] 0.0%–6.0%; European Region) to 46.1% (95% CI 29.7%–63.0%; Western Pacific Region). Following the introduction of the hepatitis B vaccine, the HBV MTCT incidence decreased from 82.9% to 15.9% in HBeAg‐positive women and from 10.3% to 2.3% in HBeAg‐negative women. Maternal peripartum antiviral treatment alongside infant immunoprophylaxis further decreased MTCT incidence to 0.3% (95% CI 0.1%–0.5%). Despite infant immunoprophylaxis, the incidences of MTCT at maternal HBV DNA levels of <2.30, 2.00–3.29, 3.00–4.29, 4.00–5.29, 5.00–6.29, 6.00–7.29 and ≥7.00 log10 IU/ml were 0.0% (95% CI 0.0%–0.0%), 0.0% (95% CI 0.0%–0.0%), 0.0% (95% CI 0.0%–0.5%), 0.6% (95% CI 0.0%–2.6%), 1.0% (95% CI 0.0%–3.1%), 4.3% (95% CI 1.8%–7.5%), and 9.6% (95% CI 7.0%–12.5%), respectively.ConclusionsHBV MTCT incidence varies across regions. The Western Pacific Region bears the heaviest burden. Peripartum antiviral prophylaxis plus infant immunoprophylaxis is promising for interrupting HBV MTCT. Regarding the HBV DNA threshold for peripartum antiviral prophylaxis, maternal HBV DNA of 4.00 log10 IU/ml or greater seems justified.
