Overcoming challenges to make e-learning a panacea for present and future crises
Authors: Looi Kim Hoe 
Published: May 2022

PurposeThis study identified salient challenges related to future preference for e-learning of undergraduates during closure of institutions of higher learning due to the Coronavirus disease 2019 (COVID-19) and put forth suggestions to overcome challenges of e-learning for present and future crises.Design/methodology/approachUndergraduates were drawn from two universities in Malaysia who normally attend conventional classroom learning. Underpinned by the literature, the challenges and future preference for e-learning were operationalised into statements. Data were collected via a self-administered questionnaire hosted on Google Forms and were analysed with Statistical Package for the Social Sciences and STATA statistical software.FindingsThe hierarchical multiple linear regression results showed that the salient challenges related to undergraduates' future preference for e-learning, in descending order, were learning outcomes, followed by disadvantages (negatively) and discipline. Moreover, there were nuanced gender differences on the relative importance of salient challenges related to future preference for e-learning.Research limitations/implicationsBecause the literature on e-learning during the closure of institutions of learning due to the COVID-19 pandemic is evolving, some salient challenges may not be captured in this study. Next, this survey was carried out in July 2020 when all courses were conducted using one hundred per cent e-learning for the first time. Hence, future replication studies may produce different results. Lastly, findings are not generalisable to other contexts as the salient challenges may be unique to the Malaysian context.Practical implicationsConcerted efforts by all stakeholders to address these salient challenges will shift e-learning in higher education closer to a panacea during present and future crises.Originality/valueThe sudden and involuntary switch from face-to-face learning to e-learning during the closure of institutions of higher learning due to the COVID-19 pandemic provided opportunity to research the salient challenges encountered by undergraduates and to overcome these salient challenges.
Action design research: integration of method support
Authors: Cronholm Stefan , Göbel Hannes 
Published: May 2022

PurposeAction design research (ADR) has become widely accepted as a prominent research method within information systems when managing design-oriented research projects. One purpose of the ADR method is to provide methodological guidance for the building of IT artefacts. However, several scholars have reported a lack of guidance of method support at the micro level. This article aims to complement the macro level of the ADR method by integrating prescriptive method support at the micro level.Design/methodology/approachA qualitative approach including direct content analysis. An empirical ADR project was analysed in order to identify method support that could be integrated into the ADR method.FindingsMethod support at the micro level was identified for all the stages of the ADR method. The method support consists of procedural support, guiding concepts, and various techniques for the documentation of project tasks stated in the ADR method.Research limitations/implicationsThe contribution to theory consists of aspects concerning the integration of macro and micro levels: relationships between normative and prescriptive support, continuous focus shifts, and method completeness.Practical implicationsThe contribution to practice consists of explicit suggestions for method support that could be integrated into the ADR method.Originality/valueThis study extends previously provided knowledge by offering empirical evidence concerning theoretical constructions consisting of explicit relationships between ADR tasks and integrated method support, and elaboration on the integration of macro and micro levels.
Forensic accounting tools for fraud deterrence: a qualitative approach
Authors: Clavería Navarrete Alberto , Carrasco Gallego Amalia 
Published: May 2022

Purpose
The purpose of this paper is to understand if forensic accounting techniques and tools could contribute to the deterrence of fraud in financial statements, considering the expertise of forensic accountant on ex post activities and that the traditional mechanisms to prevent this type of fraud have not been sufficient to stop the impact on companies, investors, auditors, employees and on society in general.

Design/methodology/approach
This research was carried out using a qualitative exploratory study with a phenomenological approach conducted through in-depth interviews with professional experts in the forensic field.

Findings
The findings confirm that the use of forensic accounting techniques and tools could contribute to the prevention of fraud in financial reporting not only when the risk of fraud has been materialized. Similar studies, about fraud prevention addressing the situation under a qualitative approach from the perspectives of its protagonists, have not been observed in the bibliographical review, so this research contributes to expanding the scientific research, the study and practice of forensic accounting.

Originality/value
From a business management perspective, this study contributes a paradigm shift from the traditional ex post forensic auditing activity toward an ex ante activity to improve management control systems within organizations anywhere in the world. Because this study is guided to prevent fraudulent financial statements, other fraud categories such as misappropriation or corruption could be addressed in other studies and various countries.
Real Estate Insights Offices – reports of my death are greatly exaggerated
Authors: French Nick 
Published: May 2022

PurposeThe aim of this Real Estate Insight is to comment upon the role that offices will play in the post-COVID 19 work environment. The impact of lockdowns, worldwide, was to accelerate the changes in office use that were already beginning in the late 2010s as changes in work culture and practice and supporting technology were slowly transforming the way in which people worked.Design/methodology/approachThis Real Estate Insight will comment upon changes in the UK market as a bellwether for global working practices. The nature of the “Insights” briefings means that this is a personal view of the author.FindingsThis paper looks at office usage in a transitional, post-COVID 19, marketplace. The findings are a reasoned conjecture that traditional office use still has a place for the workforce of the 2020s and beyond, although office use will be less intense as workers adopt a range of other working practices, including coworking and working at home, outside the four walls of the physical office building.Practical implicationsAs with all property investment, the value and performance of the property assets is interlinked with the use and demand of the space in question. There will be a rebasing of rents as the use of office space becomes less intense and the lowering of unit costs will allow companies to restructure the internal space to accommodate a more flexible working environment.Originality/valueThis is a review of the UK office market in relation to a seismic change in how workers choose to work post COVID-19.
The relationship between student motivation and academic performance: the mediating role of online learning behavior
Authors: Meng Xiangju , Hu Zhenfang 
Published: May 2022

Purpose
This paper aims to use a quantitative approach to explore the role of online learning behavior in students’ academic performance during the COVID-19 pandemic. Specifically, the authors probe its mediating effect in the relationship between student motivation (extrinsic and intrinsic) and academic performance in a blended learning context.

Design/methodology/approach
Survey data were collected from 148 students taking an organizational behavior course at one Chinese university. The data were paired and analyzed through regression analysis.

Findings
The results show that students should actively engage in online learning behavior to maximize the effects of blended learning. Extrinsic motivation was found to positively influence academic performance both directly and indirectly through online learning behavior, while intrinsic motivation affected academic performance only indirectly.

Originality/value
Through paired data on extrinsic and intrinsic motivation, online learning behavior and academic performance, this study provides a more nuanced understanding of how online learning behavior affects the focal relationship, and it advances research on the mechanisms underlying the focal relationship. Practitioners should enhance students’ online learning behavior to boost blended learning effects during the COVID-19 pandemic.
Judgments of ethically questionable financial practices: a new perspective
Authors: Sobolev Daphne , Clunie James 
Published: May 2022

Purpose Research has suggested that ethics judgments should be made from an impartial perspective. However, people are often partial about their money. This study aims to investigate the extent to which perspectives – the perspective of those who can gain from the use of a financial practice and the perspective of those who can incur losses due to it – affect lay people’s ethics and legality judgments of the practice. In addition, it asks which factors influence their investment intentions.Design/methodology/approach The study uses a between-participant scenario experiment, in which participants are presented with cases of predatory trading and front running. Each participant is asked to take either a gain or loss perspective through the formulation of the presented cases. Subsequently, all participants make ethics, legality and investment intention judgments.Findings The authors establish that perspectives significantly affect people’s ethics judgments and, to a lesser extent, their legality judgments. People’s investment intentions depend on their perspectives, too, as well as on their financial considerations, ethics judgments, legality judgments and trust.Originality/value Research has focused on relatively stable determinants of people’s ethics judgments of financial practices. This paper shows that the situational prospect of profit can sway lay people’s judgments. When people take the gain perspective, they judge financial practices to be more ethical than when they take the loss perspective. Furthermore, people’s perspectives can distort their legality judgments and influence their investment intentions.

AbstractThe practical use of cell‐based seasonal influenza vaccines is currently being considered in Japan. From the perspective of adventitious virus contamination, we assessed the suitability of NIID‐MDCK cells (NIID‐MDCK‐Cs) as a safe substrate for the isolation of influenza viruses from clinical specimens. We first established a sensitive multiplex real‐time PCR system to screen for 27 respiratory viruses and used it on 34 virus samples that were isolated by passaging influenza‐positive clinical specimens in NIID‐MDCK‐Cs. Incidentally, the limit of detection (LOD) of the system was 100 or fewer genome copies per reaction. In addition to influenza viruses, human enterovirus 68 (HEV‐D68) genomes were detected in two samples after two or three passages in NIID‐MDCK‐Cs. To further investigate the susceptibility of NIID‐MDCK‐Cs to adventitious viruses, eight common respiratory viruses were subjected to passages in NIID‐MDCK‐Cs. The genome copy numbers of seven viruses other than parainfluenza 3 decreased below the LOD by passage 4. By passaging in NIID‐MDCK‐Cs, the genome numbers of the input HEV‐D68, 1 × 108 copies, declined to 102 at passage 3 and to under the LOD at passage 4, whereas those of the other six viruses were under the LOD by passage 3. These results implied that during the process of isolating influenza viruses with NIID‐MDCK‐Cs, contaminating viruses other than parainfluenza 3 can be efficiently removed by passages in NIID‐MDCK‐Cs. NIID‐MDCK‐Cs could be a safe substrate for isolating influenza viruses that can be used to develop cell‐based influenza vaccine candidate viruses.
Spatial aggregation of herbivores and predators enhances tri‐trophic cascades in paddy fields: Rice monoculture versus rice‐fish co‐culture

Published: May 2022

Abstract

Rice‐fish co‐culture system has a history of more than 2,000 years in Asia and has been recognized as one of FAO's Globally Important Agricultural Heritage Systems (GIAHS). To date, few studies have explored rice‐fish co‐culture effects on the relationship between predator–prey aggregations and associated tri‐trophic cascades of predatory spiders, insect herbivores and rice. Indeed, predators have been shown to increase prey spatial aggregation but it is still not clear how fish (tertiary consumers) affect aggregations and interactions of their prey on multiple trophic levels (i.e. predatory spiders and rice insect herbivores).

Here, we conducted a 2‐year experiment to measure the abundance and distribution of herbivores (leafrollers, stemborers and planthoppers) and their predators (spiders) along with rice yield in rice‐fish co‐culture versus monoculture‐rice (fish free) systems in eastern China. We analysed spatial aggregations of herbivores and predators using geostatistics and used correlations to examine tri‐trophic interactions.

Results showed that co‐culture enhanced predatory spider and herbivore spatial aggregations, which in turn increased biocontrol of herbivores by predators, decreased herbivore damage and increased rice productivity.

Synthesis and applications. Fish presence increased spatial aggregation of two different trophic levels, which enhanced a tri‐trophic cascade of predatory spiders, insect herbivores and rice in co‐culture systems. Our approach linking spatial aggregations of herbivores and predators with trophic cascades can be applied to study trophic interactions in other ecosystems. Incorporating fish into monoculture paddy fields can increase both natural pest control by predatory spiders and crop productivity via aggregation, and thus increase multiple ecosystem services.
Prioritization vs. congestion on platforms: evidence from Amazon's Twitch.tv
Authors: Tudón José 
Published: May 2022

AbstractThis article studies the efficient use of prioritizing certain content over others in Amazon's Twitch.tv, a live streaming service, taking into account the trade‐off between entry and congestion. I specify and estimate supply and demand models for live video, and a congestion model. Using technological shocks, I identify congestion costs for content providers and their consumers. Using shocks in prioritization, I identify its benefits. With estimated preferences and technological parameters, I construct counterfactuals. Without congestion, demand doubles. A supply‐side Pigouvian tax on traffic is preferred to a demand‐side one. Without prioritization, consumer welfare drops by 10%.

Published: May 2022

AbstractBackgroundAs an endocytic nanosicle involved in intercellular communication, an exosome can efficiently deliver drugs from one cell to another and deliver therapeutic short interfering RNA (siRNA) to target cells. This is conducive to gene therapy for cancers. In this study, an exosome was used as the siRNA‐loaded substrate to prepare a targeted siRNA‐loaded PD‐L1 exosome and evaluate its function against lung cancer.MethodsThe optimal preparation process and binding ratio of the targeted nanovesicle/siRNA complex was determined by detecting the particle size, potential, and other physical parameters in combination with cell binding and uptake capacity of exosome complexes. The biological cell behavior of targeted exosome nanosicles was evaluated through cytotoxicity, apoptosis, and the cell uptake capacity.ResultsA targeted exosome nanovesicle capable of loading siRNA and characterized with low toxicity, high loading rate, and the ability to be used for targeted tumor cell gene therapy was constructed.ConclusionThe PD‐L1 targeting exosome can be used as an efficient siRNA delivery carrier, which is an efficient and safe nanocarrier for tumor targeted gene therapy.
Detailed classification of second‐degree perineal tears in the delivery ward: an inter‐rater agreement study
Authors: Macedo Marthe Dalevoll , Ellström Engh Marie , Siafarikas Franziska 
Published: May 2022

AbstractIntroductionSecond‐degree perineal tears can vary widely as to the extent of trauma, which may be relevant for women's pelvic floor health postpartum. However, the short‐ and long‐term consequences of second‐degree perineal tears are poorly understood, likely due to the lack of a detailed classification system. Such a classification system for second‐degree tears has been suggested but the inter‐rater agreement has not yet been assessed. The aim of this study was to assess the inter‐rater agreement of the already established classification system for perineal tears recommended by the Royal College of Obstetricians and Gynaecologists (RCOG classification) among midwives. Further, we aimed to assess the inter‐rater agreement of a classification system that provides three sub‐categories for second‐degree perineal tears.Material and methodsThis was an inter‐rater agreement study, conducted at Akershus University Hospital in Norway from 31 August to 29 November 2020. All midwives working in the delivery ward participated in the study. Midwives classified the integrity of the perineum of all women delivering vaginally within the study period. During the first month of the study, tears were classified by two midwives who were blinded to each other's findings, and the agreement of the RCOG classification was assessed. The following month, the detailed classification system was introduced to the midwifery staff. The last month, perineal tears were classified by two midwives using the detailed classification system, and the agreement was assessed. Inter‐rater agreement was measured using Fleiss multirater kappa (k) and Kendall's coefficient of concordance (KCCw).ResultsThe inter‐rater agreement for the RCOG classification was good to very good, with k = 0.705 (95% confidence interval [CI] 0.62–0.79, P < 0.001), KCCw = 0.928 (P < 0.001). The inter‐rater agreement for the detailed classification system was good to very good, with k = 0.748 (95% CI 0.67–0.83, P < 0.001), KCCw = 0.956 (P < 0.001).ConclusionsThe inter‐rater agreement among midwives using both the RCOG classification and the detailed classification system among midwives was good to very good. The detailed classification system provides additional information about the extent of tissue trauma in second‐degree tears, warranted for future research on women's pelvic floor health postpartum.

AbstractObjectivesTo highlight the role of percutaneous left ventricular assist device (LVAD) decommissioning as a safe procedure after myocardial recovery in patients with advanced heart failure.BackgroundThe HeartMate3 LVAD (Abbott, Chicago, IL, USA) is designed to provide circulatory support with enhanced hemocompatibility for patients with advanced heart failure. Most VADs are used as a bridge to heart transplantation; however, in certain cases, myocardial function recovers, and VADs can be explanted after the patient is weaned. Although surgical explantation remains the gold standard, minimally invasive percutaneous decommissioning has been described as a successful alternative. In this study, we present our experience, one‐year outcomes, and adverse events associated with percutaneous LVAD decommissioning.MethodsWe conducted a retrospective review of data from six consecutive patients who underwent percutaneous LVAD decommissioning.ResultsSix patients were enrolled in the study. For all six patients, HM3 decommissioning was completed at least 6 months ago. No technical complications were documented. No strokes were observed within the study period, and the ejection fraction improved. The mean follow‐up duration was 18 ± 8.5 months, and the survival rate was 100%.ConclusionPercutaneous HeartMate3 decommissioning appears to be safe. In particular, the survival after the procedure was 100%, and no events, especially thromboembolic ones, occurred.

AbstractAimTo validate child‐adapted shortened versions of the Irritable Bowel Syndrome‐Behavioural Responses Questionnaire (IBS‐BRQ; short scale denoted BRQ‐C) and the Visceral Sensitivity Index (VSI; short scale denoted VSI‐C) for children with functional abdominal pain disorders (FAPDs).MethodsA child psychologist supervised by a child gastroenterologist was responsible for shortening the scales (BRQ‐C, 11 items; and VSI‐C, 7 items). Then, a sample of 89 children aged 8–12 years with FAPDs was used in the validation. Construct validity was assessed with correlations. Measures included gastrointestinal symptoms, quality of life, pain intensity and anxiety. Also, internal consistency, test–retest reliability, administration time and factor structure were assessed.ResultsInternal consistency for the BRQ‐C and the VSI‐C was α = 0.84 and α = 0.80, respectively. Correlations with related scales were similar between child‐adapted scales and original scales, indicating construct validity equivalence. Correlations between short scales and original scales were high. Mean administration time was reduced by 47% (BRQ‐C) and 42% (VSI‐C), compared with original scales. Test–retest reliability was r = 0.72 for BRQ‐C and r = 0.83 for VSI‐C. BRQ‐C had two factors (Avoidance and Bowel control). VSI‐C had a unifactorial structure.ConclusionThe BRQ‐C and the VSI‐C were found to be time‐saving, reliable and valid for children with FAPDs.
The effect of trust in government on elections during the COVID‐19 pandemic in South Korea
Authors: Yu Seungwon , Yoo Eun Ji , Kim Suhee 
Published: May 2022

AbstractRecent studies focused on the pandemic's effect on elections, examining partial government interventions (e.g., lockdowns) or a specific area within a country. Governments have taken a variety of nationwide measures in reaction to the pandemic, and they may or may not be working in the best interests of citizens. If citizens believe that a government demonstrates competence, benevolence and honesty in making pandemic‐related decisions, trust in that government may grow, affecting election results. Using data for trust in government and nationwide elections during the pandemic in South Korea, we find that trust in government completely mediates the relationship between the number of confirmed cases of COVID‐19 and the results of elections (i.e., ruling party's win and vote share).
