Published: January 2023

PurposeCritically, to improve and manage online learning quality (OLQUAL), higher education providers need to regularly measure OLQUAL. Hence, a reliable measure of OLQUAL in higher education from the students' perspective is indispensable. Further, as a pioneer in examining OLQUAL outcomes in the online education context, we assert that satisfaction, trust and loyalty is a global assessment that follows the evaluation of OLQUAL. A model that delineates the perceived OLQUAL and its relationship with satisfaction, trust and loyalty are currently absent. Grounded on the cognition–affective–conation framework – this study presents the indicators of perceived OLQUAL and its influence on students' satisfaction and trust which further influences their loyalty.Design/methodology/approachTo measure the OLQUAL instrument and proposed relationships – data were collected from 232 online undergraduate and postgraduate students. The results of confirmatory factor analysis measure five dimensions of perceived OLQUAL – comprising system quality, administrative quality, educational quality, transformative quality and social quality. Further, the proposed relationships were tested using structural equation modelling.FindingsThis study has successfully measured a second-order OLQUAL model on five primary quality dimensions (i.e. systems, administrative, educational, transformative and social). The findings confirm that students' satisfaction alone does not play a mediating role; rather, satisfaction and trust play a sequential mediating role between OLQUAL and loyalty.Originality/valueOur new model provides a new tool for institutions and researchers to evaluate the quality of online education programs, as well as identify their strategy in developing and providing high-quality online learning to students.
Hospitality and tourism firms' board characteristics, board policies and tourism sector performance: what is the nexus?
Authors: Nimer Khalil , Kuzey Cemil , Uyar Ali 
Published: January 2023

PurposeThis study investigated the micro–macro link in the hospitality and tourism (H&T) sector, specifically considering whether the gender diversity, independence and board attendance rates of H&T firms' boards, alongside the moderation effect of board policies, played a significant role in tourism sector performance.Design/methodology/approachThe 2011–2018 data were retrieved from the World Bank and the Thomson Reuters Eikon databases, and fixed effects panel regression was conducted.FindingsWhile female directors were a significant driver of tourism sector performance in terms of tourist arrivals and tourism receipts, independent directors were effective in improving tourist arrivals only. Furthermore, moderation analyses demonstrated the inefficacy of board policies in enhancing these directors' contributions to the sector's development. Moreover, the findings revealed the inefficiency of board meetings.Practical implicationsConcerning the efficacy of board policies, the results suggest that firms' boards should review and revise their policies. Surprisingly, while board-diversity policies made no difference to female directors' role in the sector's development (although females were influential), board-independence policies produced unexpected results. In the absence of a board-independence policy, independent directors are influential, but if a policy exists, they are not.Originality/valueAlthough prior firm-level studies tested whether board characteristics enhanced firms' performance in the H&T sector, they did not investigate whether board characteristics promoted tourism sector performance. Moreover, the moderating effect of board policies on boards' structures and tourism sector performance has not yet been examined.
Food import demand with structural breaks, economic embargo and the COVID-19 pandemic in a wealthy, highly import-dependent country

Published: January 2023

PurposeQatar, a wealthy country with an open economy has limited arable land. To meet its domestic food demand, the country heavily relies on food imports. Additionally, the over three year-long economic embargo enforced by regional neighbors and the covariate shock of the COVID-19 pandemic have demonstrated the country's vulnerability to food insecurity and potential for structural breaks in macroeconomic data. The purpose of this paper is to examine short- and long-run determinants of Qatar's imports of aggregate food, meats, dairy and cereals in the presence of structural breaks.Design/methodology/approachThe authors use 24 years of food imports, gross domestic product (GDP) and consumer price index (CPI) data obtained from Qatar's Planning and Statistics Authority. They use the autoregressive distributed lag (ARDL) cointegration framework and Chambers and Pope's exact nonlinear aggregation approach.FindingsUnit root tests in the presence of structural breaks reveal a mixture of I (1) and I (0) variables for which standard cointegration techniques do not apply. The authors found evidence of a significant long-run relationship between structural changes and food imports in Qatar. Impulse response functions indicate full adjustments within three-quarters of a year in the event of an exogenous shock to imports.Research limitations/implicationsAn exogenous shock of one standard deviation on this variable would reduce Qatar's food imports by about 2.5% during the first period but recover after the third period.Originality/valueThe failure of past aggregate food demand studies to go beyond standard unit root testing creates considerable doubt about the accuracy of their elasticity estimates. The authors avoid that to provide more credible findings.

Published: January 2023

PurposeThis study seeks to answer (1) how perceived neighborhood collective efficacy and disorder affect residents' cooperation with the police, both directly and indirectly through perceptions of the police and (2) how Arab American ethnicity moderates the linkages between perceived collective efficacy, disorder and cooperation.Design/methodology/approachRelying on survey interview data from a probability sample of 414 residents in Dearborn and Dearborn Heights, MI and path model analysis, this study tests an explanatory model of public cooperation with the police that integrates both neighborhood and policing factors.FindingsPerceived neighborhood disorder undermines residents' desires to cooperate, and this influence is chiefly direct. Meanwhile, although no significant total effect, perception of neighborhood collective efficacy does have a positive effect on cooperation through the mediator of positive assessment of police effectiveness. Further, collective efficacy has a direct, positive effect on cooperation among Arab Americans only. Finally, perceptions of police equal treatment and effectiveness, rather than procedural justice, are significant correlates of public cooperation.Originality/valueThis study contributes to the extremely limited literature on policing and Arab American communities. The findings can deepen the understanding on why and for which groups neighborhood context is related to cooperation with the police. Findings can also add to the knowledge base for designing policies and practices that help secure and promote public support and cooperation in both Arab and non-Arab communities.
Parametric experimental investigation of additive manufacturing-based distal ulna bone plate: a response surface methodology-based design approach
Authors: Sharma Shrutika , Gupta Vishal , Mudgal Deepa 
Published: January 2023

Purpose
The implications of metallic biomaterials involve stress shielding, bone osteoporosis, release of toxic ions, poor wear and corrosion resistance and patient discomfort due to the need of second operation. This study aims to use additive manufacturing (AM) process for fabrication of biodegradable orthopedic small locking bone plates to overcome complications related to metallic biomaterials.

Design/methodology/approach
Fused deposition modeling technique has been used for fabrication of bone plates. The effect of varying printing parameters such as infill density, layer height, wall thickness and print speed has been studied on tensile and flexural properties of bone plates using response surface methodology-based design of experiments.

Findings
The maximum tensile and flexural strengths are mainly dependent on printing parameters used during the fabrication of bone plates. Tensile and flexural strengths increase with increase in infill density and wall thickness and decrease with increase in layer height and wall thickness.

Research limitations/implications
The present work is focused on bone plates. In addition, different AM techniques can be used for fabrication of other biomedical implants.

Originality/value
Studies on application of AM techniques on distal ulna small locking bone plates have been hardly reported. This work involves optimization of printing parameters for development of distal ulna-based bone plate with high mechanical strength. Characterization of microscopic fractures has also been performed for understanding the fracture behavior of bone plates.
Autoimmunity‐related neutrophilic dermatosis after coronavirus disease 2019 vaccination: A case report and literature review

Published: January 2023

AbstractAutoimmune diseases triggered by coronavirus disease 2019 (COVID‐19) mRNA vaccination have been emerging. Here, we report the case of a 27‐year‐old Japanese man with autoimmunity‐related neutrophilic dermatosis, occurring as an initial cutaneous manifestation of systemic lupus erythematosus with Sjögren syndrome after the second dose of the Pfizer/BioNTech COVID‐19 vaccination. The patient presented with urticarial erythema and partially annular erythema on the trunk and extremities with severe pruritus. Histopathological analysis showed vacuolar degeneration at the dermo‐epidermal junction and interstitial neutrophil infiltration. We reviewed eight patients, including the aforementioned patient, with exacerbation or new‐onset of SLE after COVID‐19 vaccination and found the patient had relatively mild symptoms, itchy annular erythema, and positive anti‐SS‐A/SS‐B antibodies. COVID‐19 mRNA vaccination can induce the production of type‐I interferon, which plays a crucial role in the pathogenesis of SLE and may cause autoimmunity‐related neutrophilic dermatosis in susceptible individuals. In the case that itchy annular erythema develops approximately 2 weeks after the vaccination, the possibility of systemic or cutaneous lupus erythematosus should be considered. For an accurate diagnosis, dermatologists should obtain a recent vaccination history and perform complete antibody profiling and skin biopsy for patients presenting with annular or erythema multiforme‐like lesions.

Published: January 2023

AbstractWild‐type herpes simplex virus (HSV) strains infrequently mediate cell–cell fusion in cell cultures and barely induce large multinucleated cells. In this study, we established a system to quantify infrequent cell–cell fusion induced by wild‐type HSV strains. The established system clarified that the HSV‐1 envelope glycoprotein B and its N‐glycosylation at asparagine at position 141 were required for efficient cell–cell fusion. This study provides a link between cell–cell fusion induced by wild‐type HSV‐1 and viral pathogenesis in vivo.

AbstractBackgroundThe diverse stages of the COVID‐19 pandemic led to several social circumstances that influenced daily life and health behavior.PurposeTo evaluate changes in cardiovascular risk factors and physical activity among children and young adults with type 1 diabetes (T1D) during the COVID‐19 pandemic in Germany compared to previous years.MethodsA total of 32 785 individuals aged 6–21 years at baseline with T1D from the German diabetes patient follow‐up (DPV) registry contributed data on 101 484 person‐years between 2016 and 2021. The first treatment year of each individual within this period was considered as baseline. Based on trends from 2016 to 2019, we estimated differences in body mass index‐SD score (BMI‐SDS), blood pressure (BP‐SDS), and lipid levels (non‐high‐density lipoprotein [non‐HDL]) between observed and predicted estimates for the years 2020 and 2021 using linear regression analysis standardized for age, diabetes duration, sex, and migratory background. The proportion doing organized sports and smoking cigarettes was analyzed using multivariable logistic regression models.ResultsBMI‐SDS increased constantly from 2016 to 2021 without a significant increase above expected values for 2020/2021. Systolic BP‐SDS (difference observed vs. expected with 95% confidence interval, 2020: 0.10 [0.07–0.14], 2021: 0.17 [0.14–0.20]) and non‐HDL (2020: 2.7 [1.3–4.1] mg/dl, 2021: 4.1 [2.7–5.5] mg/dl) were significantly increased (all p < .001) in both pandemic years. The proportion of subjects participating in organized sports was reduced from over 70% in prepandemic years to 35%–65% in diverse stages/waves of the COVID‐19 pandemic. The percentage smoking cigarettes did not change.ConclusionsWe describe an increase in BP and atherogenic lipid levels coinciding with a reduction in physical activity but no acceleration of the prepandemic increases in BMI‐SDS among young people with T1D during the COVID‐19 pandemic.

AbstractAimInvestigating parent satisfaction with care is important to guide quality development. In this study, we translated and validated a Danish version of the empowerment of parents in the intensive care – neonatology (EMPATHIC‐N) questionnaire to determine validity in Danish contexts.MethodA psychometric study design was applied. Translation was performed according to recommended international standards. Confirmatory factor analyses including standardised factor loadings, Cronbach's α reliability estimates, congruent validity and non‐differential validity testing were applied. The study was performed from June 2017 to November 2019 at a 33‐bed level IV neonatal intensive care unit.ResultsParticipants were 311 parents (response rate = 42,8%). Confirmative factor analyses disclosed a moderate model fit of the instrument with Comparative Fit Index (CFI) values of 0.83–0.92. Cronbach's α showed good reliability (0.82–0.93). Congruent validity showed good positive correlations (0.48–0.71) between the instrument domains and four overall satisfaction indicators. In search of improved model fit, a version including 27 items was tested. This version showed a better model fit with CFI values of 0.92–0.99 and satisfactory Cronbach's α values.ConclusionsModel fit for the Danish full EMPATIC‐N was moderate. The shorter version showed better psychometric properties.

Published: January 2023

AbstractObjectivesThere is a critical need to better understand the factors underlying the increased suicide risk for youth with bipolar disorder (BD) in order to develop targeted prevention efforts. This study aimed to examine differences in characteristics of suicide ideation (SI) in youth with BD compared to youth with major depressive disorder (MDD) that may be associated with increased suicide risk.MethodsOne hundred and fifty‐one participants (92 MDD and 59 BD), ages 13–21, completed a diagnostic interview and clinical assessments. Lifetime symptoms of SI and SA were assessed using the Columbia Suicide Severity Rating Scale. Ordinal logistic regression models were used to investigate whether the diagnostic group predicted the severity and intensity of the most severe or most common SI with the age of onset, age, and gender as covariates.ResultsCompared to MDD youth, BD youth were more likely to report experiencing more severe SI, p = 0.039, experiencing the most severe SI more frequently, p = 0.002, having less control of the most severe SI, p = 0.012, and that deterrents were less likely to stop them from acting on the most severe SI, p = 0.006.ConclusionThis study highlights differences in the severity and intensity of SI in youth with BD and suggests that youth with BD have greater difficulty inhibiting thoughts of SI which may lead to less resistance to suicide action. Findings underscore the need for a more detailed assessment of SI in youth with BD to better understand SI as a proximal risk factor for future SA and a potential target for intervention.
Brain heterotopia formation by ciliopathic breakdown of neuroepithelial and blood‐cerebrospinal fluid barriers

Published: January 2023

AbstractThe developmental functions of primary cilia and the downstream signaling pathways have been widely studied; however, the roles of primary cilia in the developing neurovascular system are not clearly understood. In this study, we found that ablation of genes encoding ciliary transport proteins such as intraflagellar transport homolog 88 (Ift88) and kinesin family member 3a (Kif3a) in cortical radial progenitors led to periventricular heterotopia during late mouse embryogenesis. Conditional mutation of primary cilia unexpectedly caused breakdown of both the neuroepithelial lining and the blood‐choroid plexus barrier. Choroidal leakage was partially caused by enlargement of the choroid plexus in the cilia mutants. We found that the choroid plexus expressed platelet‐derived growth factor A (Pdgf‐A) and that Pdgf‐A expression was ectopically increased in cilia‐mutant embryos. Cortices obtained from embryos in utero electroporated with Pdgfa mimicked periventricular heterotopic nodules of the cilia mutant. These results suggest that defective ciliogenesis in both cortical progenitors and the choroid plexus leads to breakdown of cortical and choroidal barriers causing forebrain neuronal dysplasia, which may be related to developmental cortical malformation.
Thyroid function in infants born to women with hypothyroidism: An observational study at an Australian tertiary perinatal centre

Published: January 2023

AbstractObjectiveConcerns have been raised regarding thyroid dysfunction in infants born to women with hypothyroidism including those with autoimmune hypothyroidism. This concern has led to the practice of thyroid function testing in the early neonatal period. We evaluated the practice of performing a routine thyroid function test around 2 weeks of age in all healthy full‐term infants (≥37 weeks gestation) born to women with hypothyroidism to identify thyroid dysfunction.Design, Patients, and MeasurementsThis retrospective, observational single centre study included full‐term infants born to women with hypothyroidism, including non‐Graves' autoimmune hypothyroidism, over a 3‐year period. Preterm infants and those born to women with Graves' disease or thyroidectomy were excluded.ResultsOf the 790 mother‐infant dyads, 780 infants (99%) had normal thyroid function. Only 10 infants (1%) had thyroid stimulating hormone (TSH) levels > 10mIU/L at 2 weeks of age (range 10.25–106.37 mU/L). Of these, follow‐up thyroid function normalized in nine infants within 2 weeks. A routine newborn screening test identified congenital hypothyroidism in one infant. No infant born to women with known presence of anti‐thyroid antibodies had TSH levels > 10 mIU/L. Thyroid function was normal for most infants where maternal anti‐thyroid antibodies were not known (125/133, 94%).ConclusionsInfants born to women with hypothyroidism (including autoimmune hypothyroidism) had normal thyroid function in the early neonatal period. A small proportion of infants may develop TSH levels > 10 mU/L that normalizes by 4 weeks of age. The practice of routine thyroid function testing for this cohort in addition to newborn screening test offers no additional benefit.
Progress and opportunities in advancing near‐term forecasting of freshwater quality

Published: January 2023

AbstractNear‐term freshwater forecasts, defined as sub‐daily to decadal future predictions of a freshwater variable with quantified uncertainty, are urgently needed to improve water quality management as freshwater ecosystems exhibit greater variability due to global change. Shifting baselines in freshwater ecosystems due to land use and climate change prevent managers from relying on historical averages for predicting future conditions, necessitating near‐term forecasts to mitigate freshwater risks to human health and safety (e.g., flash floods, harmful algal blooms) and ecosystem services (e.g., water‐related recreation and tourism). To assess the current state of freshwater forecasting and identify opportunities for future progress, we synthesized freshwater forecasting papers published in the past 5 years. We found that freshwater forecasting is currently dominated by near‐term forecasts of water quantity and that near‐term water quality forecasts are fewer in number and in the early stages of development (i.e., non‐operational) despite their potential as important preemptive decision support tools. We contend that more freshwater quality forecasts are critically needed and that near‐term water quality forecasting is poised to make substantial advances based on examples of recent progress in forecasting methodology, workflows, and end‐user engagement. For example, current water quality forecasting systems can predict water temperature, dissolved oxygen, and algal bloom/toxin events 5 days ahead with reasonable accuracy. Continued progress in freshwater quality forecasting will be greatly accelerated by adapting tools and approaches from freshwater quantity forecasting (e.g., machine learning modeling methods). In addition, future development of effective operational freshwater quality forecasts will require substantive engagement of end users throughout the forecast process, funding, and training opportunities. Looking ahead, near‐term forecasting provides a hopeful future for freshwater management in the face of increased variability and risk due to global change, and we encourage the freshwater scientific community to incorporate forecasting approaches in water quality research and management.
