Authors: Baber Hasnan , Fanea-Ivanovici Mina , Lee Yoo-Taek , Tinmaz Hasan 
Published: February 2022

Purpose
Digital literacy is not the mere ability to use a digital device or know to use various software. It is a domain of exploration for sociology, psychology, education and, of course, technology. This study aims to present a quantitative analysis of the literature on digital literacy using a bibliometric approach.

Design/methodology/approach
Using data from the Web of Science database, the importance of the research is evaluated by reviewing 2307 publications and examining the yearly publication, field category productivity, citation structure, most cited resources, documents, most-cited authors, most productive authors, and country in the field of digital literacy. Further, a cluster analysis is conducted to see the most recurrent keywords and emerging trends in this field. At last, the authors analyzed the thematic progression of keywords over these five years based on the normalized citations. Additionally, a graphical representation of the bibliometric data using VOSviewer is presented in the paper.

Findings
The results suggest a steady rate of publication in this field, with most of the research published in education and library fields and the USA leading the country in this realm. The emerging themes in this field are ‘Fake News’, ‘Competence’, ‘Educational Technology’, ‘Health Literacy’, ‘Self-Efficacy’ and, interestingly, ‘COVID-19’. The results also revealed that COVID-19 has been examined and associated with fake news, higher education, social media and information literacy.

Originality/value
This paper provides an overall summary of the most recent research work published from 2017 to 2021 on digital literacy in the backdrop of COVID-19. The study presents the thematic progression over the years and particularly the new keywords that emerged in the limelight of the pandemic. It contributes by updating the existing body of knowledge in the field of digital literacy and presents preliminary results related to COVID-19.

Authors: Kalyanaram Gurumurthy , Saini Gordhan K. , Mony Suresh , Jayasankaran N. 
Published: February 2022

Purpose
Pricing is always a fundamental marketing element. In the digital marketing/e-commerce context, there are two universal phenomena: desire to micro-segment and customize, and the adverse reaction upon unfair perception of price. A third related question is how should firms consider price increases and decreases? Specifically, this paper aims to address the following three research and practice questions: What are the theoretical underpinnings of perception of fairness/unfairness in pricing, and what are the findings? What are the theoretical underpinnings of response to price increases and decreases? What should be online pricing strategy, consistent with the findings on (un)fairness perception of pricing and response to price increases and decreases?

Design/methodology/approach
The present approach is integrative review and critical analyses, and synthesis. The review dates back to 1960s, and is inter-disciplinary, including apposite findings in behavioral science, economics, marketing and operations management/research. The authors search for insights with significant empirical support to address these questions.

Findings
Perception of unfair price impacts consumer choice, probability of purchase, intent to buy and attitude to product/service/firm adversely. Consumers react differently to perceived unfair and fair prices. Consumers react more strongly and negatively to perceived unfair prices (compared to prices perceived to be fair) in their intent to buy and other related metrics. Consumers react differently to price increases and price decreases relative to the reference price. Consumers react more strongly to price increases than to price decreases. There is substantial heterogeneity in the magnitude of loss-aversion effect, depending on the product/service category and estimation methods.

Originality/value
The authors review and discuss potential viable pricing strategies. Based on the generalizable findings, this study provides actionable insights to managers for pricing in digital marketing context. Also, the authors provide useful directions for future research.
From the attributes of smart tourism technologies to loyalty and WOM via user satisfaction: the moderating role of switching costs

Published: February 2022

PurposeThis study aims to empirically testify an integrated model, including the attributes of smart tourism technologies (STTs) (user interface [UI] design, informativeness, accessibility, personalization and interactivity), satisfaction, loyalty and word of mouth (WOM), and further investigate the potential moderating effect of switching costs (SCs) on the satisfaction–loyalty/WOM relationships.Design/methodology/approachSystematic sampling was used to collect data in Macau. Partial least squares structural equation modeling (PLS-SEM) was employed to analyze valid data collected from 332 tourists who have recently used STTs.FindingsThe results indicate that informativeness has a stronger effect on satisfaction, loyalty and WOM than UI design, accessibility and personalization; interactivity shows no significant influence on satisfaction, loyalty and WOM; satisfaction positively influences loyalty and WOM. Furthermore, procedural SCs negatively moderate the effects of satisfaction on loyalty and WOM.Originality/valueThe present study extends the knowledge about information technology and tourism (ITT) by introducing a new attribute, UI design into STT structure and confirming that UI design is an effective predictor of user satisfaction. This paper is also a pioneer study that integrates customer satisfaction with STTs with SCs to explore the mechanism of how customer loyalty and WOM are generated. Practical recommendations are provided for STT designers and destination managers to improve the overall quality of STTs and to consider carefully setting procedural SCs as a retention strategy.
Lessons from leveraging technology in auditing during COVID-19: an emerging economy perspective
Authors: Sharma Neeraj , Sharma Garima , Joshi Mahesh , Sharma Sharad 
Published: February 2022

Purpose
This study aims to examine the challenges posed by COVID-19 restrictions for audit processes in India and explore the perceptions of the profession on how technology was leveraged to conduct audits during this period. The opinions of auditors on future changes in post-COVID-19 audit practices and processes are also explored.

Design/methodology/approach
Semi-structured interviews were conducted with senior auditors working in various audit firms in major business centers in India and subjected to content and thematic analysis using the institutional theory perspective.

Findings
The auditing profession used technology to respond to COVID-19-imposed disruptions of established audit process and practices while maintaining the legitimacy of audit reports. The findings indicate that auditors now seem to strongly support the integration of emerging technologies into their auditing practices post-COVID to ensure data accuracy and transparency. The interviewees displayed keen interest in continuing remote and in-person audits to maintain audit quality in the future. The experience of COVID-19 appears to have forced the auditing profession to overcome their reluctance to adopt technologies that were previously used by only Big 4 and large audit companies.

Practical implications
The results will be of particular interest to various stakeholders concerned with aspects of the acceptance of technology-assisted audit reports such as legitimacy, required infrastructure, cost involvement and resistance to change. The findings will also assist professional bodies and policymakers in both developed and developing economies in devising useful strategies to promote technology-aided auditing during and after COVID-19. Limitations posed by inadequate infrastructure and resistance to changes must be overcomed before implementation of technology-aided audits.

Originality/value
As COVID-19 pandemic is a recent phenomenon, to the best of the authors’ knowledge, this study is one of the first few studies that have examined the use of technology to facilitate audits during the COVID-19 period, more specifically from a developing economy perspective.
Spreading the word: enablers and challenges to implementing a nature-based intervention for people living with dementia
Authors: Bray Jennifer , Evans Simon Chester , Atkinson Teresa 
Published: February 2022

Purpose
When new interventions are piloted, the implementation process often takes a back seat but can be key to ensuring that an intervention is successful. This paper aims to highlight the enablers and challenges encountered when implementing a nature-based intervention for people living with dementia.

Design/methodology/approach
The evaluation adopted a mixed methods approach including case studies, telephone interviews with delegates and interviews with participants. Thematic analysis was used to identify overarching themes relating to the enablers and challenges of implementing the intervention.

Findings
Challenges related to understanding how the intervention fitted with existing work and practicalities of what an organisation can offer to support the implementation process. A stable underlying support structure for delegates is required, along with suitable advertising, transport and facilities to support participants. While there is no “one size fits all” approach to implementing an intervention, these findings will help organisations to consider where to focus their support.

Originality/value
The implementation of interventions is often poorly understood but is important when supporting the wider roll out of an intervention. While this paper reports on a nature-based intervention, the learning will be relevant and applicable more broadly for organisations aiming to implement a new intervention and complements previous work relating to the challenges of implementing arts activities.

Published: February 2022

AbstractBackgroundAdvances in chest computed tomography (CT) have resulted in more frequent detection of subcentimeter pulmonary nodules (SCPNs), some of which are non‐benign and may represent invasive lung cancer. The present study aimed to explore the correlation between pathological diagnosis and the CT imaging manifestations of SCPNs.MethodsThis retrospective study included patients who underwent pulmonary resection for SCPNs at Shandong Provincial Hospital in China. Lesions were divided into five categories according to their morphological characteristics on CT: cotton ball, solid‐filled with spiculation, solid‐filled with smooth edges, mixed‐density ground‐glass, and vacuolar. We further analyzed lesion size, enhancement patterns, vascular aggregation, and SCPN traversing. Chi‐square tests, Fisher's exact tests, and Welch's one‐way analysis of variance were used to examine the correlation between CT imaging characteristics and pathological type.ResultsThere were statistically significant differences in the morphological distributions of SCPNs with different pathological types, including benign lesions and malignant lesions at different stages (p < 0.01). The morphological distributions of the four subtypes of invasive lung adenocarcinoma also exhibited significant differences (p < 0.01). In addition, size and enhancement patterns differed significantly among different pathological types of SCPNs.ConclusionDifferent pathological types of SCPNs exhibit significant differences based on their morphological category, size, and enhancement pattern on CT imaging. These CT characteristics may assist in the qualitative diagnosis of SCPNs.

Published: February 2022

ABSTRACTBackgroundTo investigate the effect of three different surface treatments on the microhardness and colour change of artificial enamel lesions.Materials and MethodsOne hundred bovine teeth were randomly assigned into four groups. Artificial enamel lesions were created using demineralizing solution for all groups except the sound enamel group. Different surface treatments were then performed G1: resin‐infiltrant; G2: Casein phosphopeptide–amorphous calcium phosphate (CPP‐ACP); G3: artificial saliva; G4: Sound Enamel. Each group was subdivided into three subgroups, where each subgroup was subjected to a different testing method.Subgroup 1: surface microhardness; subgroup 2: cross‐sectional microhardness; subgroup 3: colour measurement. Statistical analysis was performed by ANOVA, followed by Tukey’s post hoc test.ResultsSound enamel group recorded the highest surface and cross‐sectional microhardness results. No significant difference was found between the resin‐infiltrant group and CPP‐ACP regarding surface and cross‐sectional microhardness at different lesion depths. Resin‐infiltrant group showed the least colour change (∆E) results compared to the other groups.ConclusionResin‐infiltrant can effectively enhance surface microhardness and enamel resistance to demineralization, additionally, reduces the staining susceptibility of white spot lesions (WSLs) after treatment. CPP‐ACP application for 4 weeks seems to improve surface microhardness; however, has a limited effect in resisting staining of WSLs after treatment. © 2022 Australian Dental Association
The marginal gaps of sequentially milled lithium disilicate crowns using two different milling units
Authors: Tan K , Dudley J 
Published: February 2022

ABSTRACTBackgroundThe purpose of this study was to compare the marginal gaps of sequentially milled lithium disilicate (LDS) crowns using two different milling units.MethodsOne lower left first molar typodont tooth prepared for an LDS crown by an undergraduate student in a simulation clinic was selected. The crown preparation was scanned by a TRIOS 3 scanner and twelve LDS crowns milled by an E4D (E4DM) and a Sirona inLab MC X5 (MCX5) milling unit using identical settings. The crowns were seated onto the original crown preparation and three vertical marginal gap measurements were taken at four locations (mid‐buccal, mid‐lingual, mid‐mesial and mid‐distal) using a stereomicroscope. The mean marginal gap (MMG) was calculated for each individual tooth surface and each crown.ResultsThe MMG for the E4DM (100.40 μm) was not significantly different to the MCX5 (101.08 μm) milling unit (P = 0.8809). In both units, there was a statistically significant trend of increasing MMG with sequentially milled crowns using the same burs (E4DMP = 0.0133; MCX5P = 0.0240).ConclusionsThe E4DM and MCX5 milling units produced LDS crowns with similar MMG’s and within a clinically acceptable range but with a trend of increasing MMG when analysed sequentially. © 2022 Australian Dental Association
Switching cost and store choice
Authors: Richards Timothy J. , Liaukonytė Jura 
Published: February 2022

AbstractSwitching costs are generally regarded as anticompetitive as firms can raise prices to “locked‐in” consumers, at least up to the cost of switching to a lower‐priced alternative. However, there is some evidence, both theoretical and empirical, that tends to show the opposite. Namely, suppliers, anticipating the pool of rents potentially available, compete aggressively to acquire non‐switching consumers. Moreover, fixed shopping costs and uncertain prices imply that there is a “real option” value embedded in consumers’ shopping behavior, and which must be priced in and compensated if consumers are to switch stores. We argue that retail prices are lower when retailers use programs designed to increase customer retention, or “stickiness.” We test our theory using a panel of household‐level, store‐choice data. Contrary to the conventional wisdom, we find that loyalty is pro‐competitive and leads to lower prices than would otherwise be the case. We also find that approximately 50% of the cumulative loyalty effect is attributable to the existence of a real option due to price uncertainty and that switching costs are substantial and comprise around 12% of the average cost of a basket of groceries.

Published: February 2022

AbstractBackgroundSleep is a fundamental biological requirement, and lack of sleep has increasingly been recognized to cause metabolic consequences and adversely affect immune function. Recent articles have pointed to how sleep and sexual functions may be interlinked, involving inflammation, vascular alterations, tissue damage, and endothelial dysfunction.ObjectivesWe examined the effect of paradoxical sleep deprivation on sexual behavior and hemogram parameters in male rats. In addition, we also explored whether 7 days of recovery sleep is sufficient to offset these detriments.Materials and methods Male rats were given sexual experience through training. At the fifth test, the sexually vigorous males were randomly separated into three experimental groups: paradoxical sleep deprivation (rats submitted to 96 h of paradoxical sleep deprivation, n = 6), recovery sleep (recovery sleep 7 days after paradoxical sleep deprivation, n = 6), and control (n = 10). We evaluated the sexual behaviors of three groups. Blood samples were collected to analyze hemogram parameters.ResultsIn this study, we recognized that repeated copulatory tests can lead to changes in sexual behavior over time. We found that 96 h of acute sleep deprivation impaired the sexual behavior of male rats. Our results demonstrated that 96 h of paradoxical sleep deprivation also increased levels of white blood cell subpopulations, in particular neutrophils. Recovery sleep after sleep deprivation has a certain reversal effect on white blood cell subgroups and impairment of sexual behavior, with some signs that not all levels were back to baseline even after 7 days of recovery.ConclusionIn general, we found that 96 h of paradoxical sleep deprivation impaired the sexual behavior of male rats. Our results demonstrated that paradoxical sleep deprivation can cause systemic inflammation by affecting white blood cell subpopulations, in particular neutrophils. Seven days of recovery sleep after sleep deprivation has a certain reversal effect to these impairments.
Testing the assumptions of customized intrauterine growth charts using national birth studies
Authors: Hocquette Alice , Monier Isabelle , Blondel Béatrice , Dufourg Marie‐Noëlle , Heude Barbara , Zeitlin Jennifer 
Published: February 2022

AbstractIntroductionCustomized intrauterine growth charts are widely used for growth monitoring and research. They are based on three assumptions: (1) estimated fetal weight (EFW) has a normal distribution with a constant coefficient of variation at all gestational ages; (2) Hadlock’s growth curve accurately describes the relation between EFW and gestational ages; (3) associations between EFW and the fetal and maternal characteristics included in the customization model (fetal sex, pre‐pregnancy weight, height, parity) are proportional throughout pregnancy. The aim of this study was to test whether these underlying assumptions are verified.Material and methodsData came from (1) the French Longitudinal Study of Children (ELFE) cohort, which recruited births after 32 weeks' gestation in 349 maternity hospitals in France in 2011, and (2) the National Perinatal Survey, which included births from all French maternity hospitals in 2016. The study population included, respectively, 6 920 and 8 969 singleton non‐malformed term live births with data on customization characteristics and EFW. We computed the coefficient of variation by gestational age and then modeled the association of gestational age, maternal and fetal characteristics with EFW at the second and third trimester ultrasound and with birthweight using linear regression. To assess the proportionality of the impact of maternal and fetal characteristics, we computed the percent change in weight associated with these characteristics at these three time points.ResultsThe coefficient of variation was close to 12% at each gestational age, but EFW was not normally distributed, leading to small but systematic underestimation of fetuses under the 10th percentile. Weights representing the 50th and 10th percentiles based on Hadlock’s growth trajectory were lower than observed or predicted weights. Most characteristics more strongly impacted weight at birth than during pregnancy. In the French Longitudinal study of Children (ELFE) cohort, boys were 1.8% (95% confidence interval [CI] 1.3–2.4) heavier than girls in the third trimester, whereas this percentage was 4.6% (95% CI 4.0–5.2) at birth. In the National Perinatal Survey, these percentages were 2.3% (95% CI 1.8–2.8) and 4.3% (95% CI 3.8–4.8).ConclusionsThese results from two independent sources revealed discrepancies between routine clinical EFW data used for growth monitoring and the customized growth model’s assumptions.
Prevalence of endometriosis and adenomyosis at transvaginal ultrasound examination in symptomatic women
Authors: Orlov Sofie , Jokubkiene Ligita 
Published: February 2022

AbstractIntroductionPrevalence of endometriosis is commonly reported based on surgery findings and varies widely depending on study population and indication for surgery. Symptoms such as dysmenorrhea, pelvic pain, dyspareunia, dysuria, and dyschezia can be associated with endometriosis and adenomyosis. Transvaginal ultrasound examination is proposed to be the first‐line diagnostic method, nevertheless there are no published ultrasound‐based studies reporting prevalence of endometriosis and adenomyosis in symptomatic women other than those scheduled for surgery. The aim of this study was to determine the prevalence of endometriosis and adenomyosis as assessed by transvaginal ultrasound in women with symptoms suggestive of endometriosis and adenomyosis.Material and methodsThis is a retrospective cross‐sectional study performed at a tertiary‐care center including 373 symptomatic women who were systematically examined with transvaginal ultrasound by an experienced ultrasound examiner. Before ultrasound examination women filled in a questionnaire including self‐assessment of the severity of their symptoms (dysmenorrhea, chronic pelvic pain, dyspareunia, dysuria, dyschezia) using a visual analog scale. Abnormal findings in the uterus, ovaries, bowel, urinary bladder, uterosacral ligaments, and rectovaginal septum were noted, and their size and location were described. Prevalence of endometriosis, adenomyosis, endometrioma, and deep endometriosis in different anatomical locations was reported.ResultsPrevalence of ovarian endometrioma and/or deep endometriosis was 25% and of adenomyosis was 12%. Prevalence of endometrioma was 20% and of deep endometriosis was 9%, for each location being 8% in the bowel, 3% in the uterosacral ligaments, 3% in the rectovaginal septum and 0.5% in the urinary bladder.ConclusionsIn symptomatic women examined with transvaginal ultrasound by an experienced ultrasound examiner, ovarian endometrioma and/or deep endometriosis was found in one of four women and adenomyosis in one of nine women. Deep endometriosis was present in one of 11 women. Despite having symptoms, half of the women had no abnormal ultrasound findings.
