The effect of COVID-19 on the Egyptian exchange using principal component analysis
Authors: Ezzat Heba M. 
Published: December 2021

PurposeSince the beginning of 2020, economies faced many changes as a result of coronavirus disease 2019 (COVID-19) pandemic. The effect of COVID-19 on the Egyptian Exchange (EGX) is investigated in this research.Design/methodology/approachTo explore the impact of COVID-19, three periods were considered: (1) 17 months before the spread of COVID-19 and the start of the lockdown, (2) 17 months after the spread of COVID-19 and the during the lockdown and (3) 34 months comprehending the whole period (before and during COVID-19). Due to the large number of variables that could be considered, dimensionality reduction method, such as the principal component analysis (PCA) is followed. This method helps in determining the most individual stocks contributing to the main EGX index (EGX 30). The PCA, also, addresses the multicollinearity between the variables under investigation. Additionally, a principal component regression (PCR) model is developed to predict the future behavior of the EGX 30.FindingsThe results demonstrate that the first three principal components (PCs) could be considered to explain 89%, 85%, and 88% of data variability at (1) before COVID-19, (2) during COVID-19 and (3) the whole period, respectively. Furthermore, sectors of food and beverage, basic resources and real estate have not been affected by the COVID-19. The resulted Principal Component Regression (PCR) model performs very well. This could be concluded by comparing the observed values of EGX 30 with the predicted ones (R-squared estimated as 0.99).Originality/valueTo the best of our knowledge, no research has been conducted to investigate the effect of the COVID-19 on the EGX following an unsupervised machine learning method.
Dimensions of gastronomic experience affecting on sharing experience: place attachment as a mediator and length of stay as a moderator
Authors: Soonsan Nimit , Somkai Umaporn 
Published: December 2021

PurposeThis paper aims to investigate the impact of gastronomic experience on sharing experiences, as well as place attachment as a mediator and length of stay as a moderator.Design/methodology/approachQuantitative method was used in this study. The paper conducted an online survey from 717 international tourists who visited Phuket, a city of gastronomy.FindingsThe result revealed that four dimensions of gastronomic experience – entertainment, escapist, education and aesthetic – affected sharing experience. The mediating role of place attachment was documented. As expected, the length of stay moderated the effect of the gastronomic experience on sharing experience through place attachment as a mediator.Practical implicationsThese results could help destination managers to develop tourist experiences and enhance customers' length of stay and place attachment. On the other hand, this research contributes to the understanding of the factors that affect sharing experience in the tourism industry with a special focus on the city of gastronomy.Originality/valuePrior research shows that tourism experience provides a future tourist behavior based on effective attitudinal variables. At the present, this research provides researchers with information on how to narrow the behavior gap through a range of marketing. This study gives additional insights into the indications of what visitors will transfer into behavior and why an area that has not been addressed previously in this context.
Does eWOM influence entrepreneurial firms’ rate of diffusion of innovation?
Authors: Ahmad Alaeddin , AlMallah Manar Mousa , AbedRabbo Majd 
Published: December 2021

Purpose
This research aims to investigate the influence of electronic word-of-mouth (eWOM) on the diffusion rate of innovation in the context of entrepreneurial firms in emerging markets. It examines a comprehensive model for the effect of eWOM dimensions (including Content, Intensity, Positive Valence and Negative Valence) on the diffusion of innovations. Thus, it provides new insights on how entrepreneurial firms can use eWOM as a communication tool to facilitate the diffusion rate of innovations in emerging markets.

Design/methodology/approach
A quantitative approach was adopted, consisting of 215 responses from Jordan. Data were analysed using Linear regression analysis tools.

Findings
A significant relationship exists between eWOM dimensions (Content, Intensity, Positive Valence and Negative Valence) and the Diffusion Rate of Innovations. In emerging markets, eWOM content highlights critical information regarding consumers’ sentiments towards new products (including features, price, design), which consumers use in judging innovations. Especially when there is a high volume of eWOM about a new product, consumers are likely to gain reassurances regarding their purchase decisions. Specifically, the valence of eWOM (including reviews, complaints and suggestions) generate adoption/risk-aversion attitudes towards new products. Consequently, entrepreneurial firms must carefully analyse eWOM regarding their products and integrate them into their marketing strategy. 10;

Originality/value
This research extends the eWOM literature by developing a comprehensive model for the effect of eWOM dimensions on the diffusion of innovations. Additionally, it sheds new light on the effect of eWOM valence on consumers’ attitudes towards innovations. Finally, it provides significant theoretical and managerial implications and future research direction to deepen our understanding of the effect of eWOM on entrepreneurial firms.
Environmental disclosure on mandatory and voluntary reporting of Portuguese listed firms: the role of environmental certification, lucratively and corporate governance
Authors: Monteiro Albertina Paula , Pereira Cláudia , Barbosa Francisco Manuel 
Published: December 2021

Purpose
This study aims to construct two environmental disclosure indices (EDI), one obtained from the mandatory reporting (annual report) and the other from the voluntary reporting (sustainability report), to compare their evolution. In addition, the authors developed and evaluated a conceptual model that aims to analyse if the two EDI are affected by industry, environmental certification, lucratively and corporate governance attributes. The legitimacy, signalling and voluntary disclosure theories are used to support the theoretical relationship between the company’s characteristics, corporate governance and environmental disclosure.

Design/methodology/approach
Using the content analysis technique, the authors have developed two indices to assess the level of environmental disclosure in the companies’ mandatory and voluntary reporting. In addition, to analyse the determinants of EDI, the authors applied the technique of multiple linear regression using panel data.

Findings
Based on Portuguese listed companies (Euronext-Lisbon), the results, from 2015 to 2017, exhibited an increase of 14.6% and 25.8% for the EDI obtained from the annual reports and for EDI obtained from the sustainability reporting, respectively. In addition, the results revealed that the environmental certification, lucratively, number of members on board and number and proportion of women of the board directors tend to affect the annual reporting EDI. Regarding the sustainability reporting EDI, the results showed that the environmental certification, lucratively and proportion of independent members of the board of directors have an impact on it.

Research limitations/implications
The study focuses on quantitative rather than qualitative disclosures and it brings some insights to the theoretical field.

Practical implications
The results obtained can assist corporate decision-making processes regarding the improvement of environmental disclosure, both on the mandatory annual report and on voluntary sustainability reports.

Originality/value
This study brings new perspectives to this topical issue in accounting. Originally, this study is applied to Portuguese listed companies and it shows different trends and determinants of environmental disclosure when included in the annual reporting or sustainability reporting.

Factors effecting customer satisfaction of mobile banking in Bangladesh: a study on young users' perspective
Authors: Jahan Nusrat , Shahria Golam 
Published: December 2021

PurposeIn Bangladesh, the banking companies have huge opportunity to capture market share by properly understanding the critical aspect of customer satisfaction. This paper mainly focuses on young generation as target group to find out their differential perception. This study aims to identify most influencing factors and determine their influencing power on young customer's satisfaction and retention in mobile banking.Design/methodology/approachIt is a quantitative research with self-administered questionnaire as primary data collection instrument. Existing literature and published articles are reviewed as secondary data for hypothesis development. Out of 300 questionnaires, 279 usable questionnaires were returned and these collected data were analyzed by partial least square-structural equation model (PLS-SEM) with the use of Smart_PLS (V 327) to validate the model and test the hypothesis.FindingsThe findings of the research revealed that expense, responsiveness and relative advantage have significant influence while security and convenience have insignificant influence on satisfaction. But they are not directly related with loyalty although satisfaction and loyalty strongly related with each other.Originality/valueAlthough mobile banking is not a new issue in Bangladesh, the use of PLS_SEM to measure young user's satisfaction as the customer of mobile banking is not available in literature. So, this paper is an attempt to fill up this gap. In spite of having some limitation the research provides some practical implication for banks with better strategic insight to design mobile banking services to yield higher customer satisfaction.
Identification of defected sensors in an array of amperometric gas sensors
Authors: Dmitrzak Marta , Kalinowski Pawel , Jasinski Piotr , Jasinski Grzegorz 
Published: December 2021

Purpose
Amperometric gas sensors are commonly used in air quality monitoring in long-term measurements. Baseline shift of sensor responses and power failure may occur over time, which is an obstacle for reliable operation of the entire system. The purpose of this study is to check the possibility of using PCA method to detect defected samples, identify faulty sensor and correct the responses of the sensor identified as faulty.

Design/methodology/approach
In this work, the authors present the results obtained with six amperometric sensors. An array of sensors was exposed to sulfur dioxide at the following concentrations: 0 ppm (synthetic air), 50 ppb, 100 ppb, 250 ppb, 500 ppb and 1000 ppb. The damage simulation consisted in adding to the sensor response a value of 0.05 and 0.1 µA and replacing the responses of one of sensors with a constant value of 0 and 0.15 µA. Sensor validity index was used to identify a damaged sensor in the matrix, and its responses were corrected via iteration method.

Findings
The results show that the methods used in this work can be potentially applied to detect faulty sensor responses. In the case of simulation of damage by baseline shift, it was possible to achieve 100% accuracy in damage detection and identification of the damaged sensor. The method was not very successful in simulating faults by replacing the sensor response with a value of 0 µA, due to the fact that the sensors mostly gave responses close to 0 µA, as long as they did not detect SO2 concentrations below 250 ppb and the failure was treated as a correct response.

Originality/value
This work was inspired by methods of simulating the most common failures that occurs in amperometric gas sensors. For this purpose, simulations of the baseline shift and faults related to a power failure or a decrease in sensitivity were performed.

Published: December 2021

Abstract4′‐O‐methylpyridoxine (MPN), a recognized antivitamin B6 compound, is a potentially poisonous substance found in Ginkgo biloba L. In this work, the effects of MPN on the metabolism of vitamin B6, neurotransmitters, and amino acids were compared in the plasma and brain of young and adult rats under various administration times. Results showed that the contents of MPN residues in the plasma and brain of young rats were 12.72 and 14.76 µM higher than adult rats, respectively. Moreover, the levels of 5‐hydroxytryptamine and dopamine in the brain of young rats have decreased by 13.78% and 7.19%, respectively, compared with the control group, at 2 h after MPN administration. Furthermore, the principal component analysis revealed that MPN was an important contributor to the amino acid composition in the brain of young rats. These results suggest that age may lead to different toxic effects of MPN.Practical Application4ʹ‐O‐methylpyridoxine is primarily responsible for poisoning due to overconsumption of Ginkgo biloba seeds. This study will provide an exploratory understanding of the age‐dependent toxicity of 4ʹ‐O‐methylpyridoxine.

Published: December 2021

SummaryEffects of an environmental endocrine disruptor, para‐nonylphenol (NP) on the cell growth of a photosynthetic eukaryotic microorganism, Euglena gracilis were analysed under different cell culture conditions. Although NP did not show significant inhibitory effects on the cell growth of E. gracilis (Z and SM strains) under light culture condition, NP exhibited significant suppressive effects under dark culture condition. Exogenous supplementation with lipophilic antioxidants (α‐tocopherol, β‐carotene or 6‐O‐palmitoyl‐ascorbic acid) to E. gracilis caused strong preventive effects against NP‐induced cell growth inhibition under dark culture condition, but hydrophilic antioxidants [ascorbic acid, glutathione and epigallocatechin gallate (EGCG)] did not show significant preventive effects. NP caused significant generation of reactive oxygen species (ROS) in E. gracilis under dark culture condition, but E. gracilis under light culture condition did not show significant increase in ROS generation. Supplementation with lipophilic antioxidants to E. gracilis caused significant suppressive effects against NP‐induced cellular ROS generation under dark culture condition, but hydrophilic antioxidants did not show significant suppressive effects. Furthermore, the productivities of typical cellular antioxidants (α‐tocopherol, β‐carotene and ascorbic acid) in E. gracilis under light culture conditions were much higher than those under dark culture conditions.

Published: December 2021

AbstractPurposeDespite evidence showing the importance of structural determinants for child well‐being and the existence of policies that can promote child well‐being, many communities are not adopting these policies. Limited awareness of structural determinants may explain this gap. This study establishes the public's recognition of structural determinants and their associations with support for policies that promote child well‐being.MethodsSecondary analyses of survey data collected in 2019 from a random sample of 2496 adults in the United States. This survey asked why some children “struggle” (e.g., do poorly in school, use drugs, or get involved in crime). Respondents could select individual (e.g., lack of effort) and structural (e.g., low wages) explanations. Respondents were also asked about their support for policies that are supportive of children and families.ResultsStronger beliefs of structural explanations were associated with greater support for policies that strengthen family economics, family‐friendly work, and afford access to high‐quality early childcare and education. Beliefs in individual explanations were inversely associated with support for these policies.ConclusionsThese findings suggest increasing recognition of the structural determinants that hinder child development may help increase support for policies that are effective in improving children's outcomes.

AbstractIncreasing evidence supports the role of neurotropic herpes simplex virus 1 (HSV‐1) in the pathogenesis of Alzheimer's disease (AD). However, it is unclear whether previously reported findings in HSV‐1 cell culture and animal models can be translated to humans. Here, we analyzed clinical specimens from latently HSV‐1 infected individuals and individuals with lytic HSV infection of the brain (herpes simplex encephalitis; HSE). Latent HSV‐1 DNA load and latency‐associated transcript (LAT) expression were identical between trigeminal ganglia (TG) of AD patients and controls. Amyloid β (Aβ) and hyperphosphorylated tau (pTau) were not detected in latently HSV‐infected TG neurons. Aging‐related intraneuronal Aβ accumulations, neurofibrillary tangles (NFT), and/or extracellular Aβ plaques were observed in the brain of some HSE patients, but these were neither restricted to HSV‐infected neurons nor brain regions containing virus‐infected cells. Analysis of unique brain material from an AD patient with concurrent HSE showed that HSV‐infected cells frequently localized close to Aβ plaques and NFT, but were not associated with exacerbated AD‐related pathology. HSE‐associated neuroinflammation was not associated with specific Aβ or pTau phenotypes. Collectively, we observed that neither latent nor lytic HSV infection of human neurons is directly associated with aberrant Aβ or pTau protein expression in ganglia and brain.

AbstractIntroductionHealthcare provision has been severely affected by COVID‐19, with specific challenges in organ transplantation. Here, we describe the coordinated response to, and outcomes during the first wave, across all UK liver transplant (LT) centers.MethodsSeveral policy changes affecting the liver transplant processes were agreed upon. These included donor age restrictions and changes to offering. A “high‐urgency” (HU) category was established, prioritizing only those with UKELD > 60, HCC reaching transplant criteria, and others likely to die within 90 days. Outcomes were compared with the same period in 2018 and 2019.ResultsThe retrieval rate for deceased donor livers (71% vs. 54%; P < .0001) and conversion from offer to completed transplant (63% vs. 48%; P < .0001) was significantly higher. Pediatric LT activity was maintained; there was a significant reduction in adult (42%) and total (36%) LT. Almost all adult LT were super‐urgent (n = 15) or HU (n = 133). We successfully prioritized those with highest illness severity with no reduction in 90‐day patient (P = .89) or graft survival (P = .98). There was a small (5% compared with 3%; P = .0015) increase in deaths or removals from the waitlist, mainly amongst HU cohort.ConclusionsWe successfully prioritized LT recipients in highest need, maintaining excellent outcomes, and waitlist mortality was only marginally increased.
