The mixed blessing of supervisor bottom-line mentality: examining the moderating role of gender
Authors: Zhang Yun , Huang Qihai , Chen Hanjing , Xie Jun 
Published: August 2021

PurposeThe purpose of this paper is to investigate the double-edged effects of supervisor bottom-line mentality (BLM) on subordinates' work-related behaviors (work performance and knowledge hiding) and the moderating role of subordinate gender.Design/methodology/approachThe theoretical model was tested using a sample of 218 three-wave multi-source data collected from employees of five firms in southern China.FindingsThe results revealed that supervisor BLM is positively associated with subordinate BLM. Although subordinate BLM can enhance their work performance, it can also lead to knowledge hiding toward coworkers. Furthermore, these indirect effects are moderated by subordinate gender.Practical implicationsManagers should pay more attention to the potential positive and negative consequences of supervisor BLM and intervene to mitigate the negative impact of BLM.Originality/valueThis study is among the first to examine how supervisor BLM can be a mixed blessing and elicit both positive and negative behaviors from their subordinates. Moreover, by illuminating how subordinate gender moderates the relationship between supervisor BLM and subordinates' work-related behaviors, we enrich and extend the BLM literature.

Published: August 2021

PurposeThis paper aims to make a modest attempt to classify the Asia-Pacific countries in terms of the access to information and communication technology (ICT) to unearth the prevalence of digital divide (if any) in the Asia-Pacific region. In addition to that, this paper also examines the role played by the digital skill in bridging the digital divide in the context of Asia–Pacific countries.Design/methodology/approachSecondary data on 43 Asia-Pacific countries for the period from 2012 to 2017 was collected from International Telecommunication Union (ITU) database and World Development Indicators, World Bank. K-means clustering technique was applied to explore the natural grouping of the Asia-Pacific countries based on ICT access. The role of digital/ICT skill in narrowing the access-based digital divide was investigated using panel data regression technique.FindingsClustering of countries suggested a significant difference amongst the Asia-Pacific countries in terms of ICT access, signifying the prevalence of access based digital divide. Digital skill played pivotal role in promoting ICT access and thereby reducing the digital divide during the period of the study. Per capita income level, level of education, openness of the economy and urbanisation were observed to be the determining factors in reducing the digital divide during the period of study in the Asia-Pacific region.Originality/valueThe study makes an unique attempt to explore the role of digital/ICT skill in tapering the access-based digital divide in the context of Asia-Pacific region.

Authors: Kumar Dwivedi Vijay , Kumar Dipak 
Published: August 2021

Purpose
The purpose of this paper is related with the comparative study between graphene-based glass fiber–reinforced polymer composites and without graphene composite on polymer matrix. The current study explains the result of amalgamation of 4 Wt.% graphene oxide (GO), in comparison to without graphene, on the mechanical strength of glass fiber/epoxy (GE).

Design/methodology/approach
A hand layup technique is used for the experimental study. For this, chemical synthesis process is approached based on Hummer’s theory. For mechanical testing of glass fiber–reinforced graphene composites and without graphene composites, American Society for Testing and Materials-3039 (ASTM3039) standards was adopted. Furthermore, comparatively, composites were characterized by field emission scanning electron microscopy.

Findings
Reinforcement of 4.0 Wt.% GO in epoxy matrix material showed 7.46% and 12.31% improvement in mechanical strength and elongation, respectively. Scanning electron microscopy results showed the influence of graphene cumulations in the failure of GO-reinforced GE (GO-GE) composites.

Originality/value
The inimitable things of graphene grounded nanofillers have encouraged in the world of material for their thinkable manipulation in glass fiber polymeric composites. In this work, for the first time, graphene is used as nanofiller in glass fiber epoxy coatings, and their fractography study is investigated.
Explaining citizens’ pro‐environmental behaviours in public and private spheres: The mediating role of willingness to sacrifice for the environment
Authors: Tsai Chin‐Chang , Li Xiangyu (Dale) , Wu Wei‐Ning 
Published: August 2021

AbstractPrior public administration research emphasises the importance of environmental protection and sustainability, but most studies have focused on governmental actions and public employees’ pro‐environmental behaviours (PEBs). Little is known about why and how citizens perform PEBs in their public or private spheres. To fill the research gap, we draw from related literature and develop a conceptual model explaining how citizens’ perceptions of public values, government, and the environment impact citizens’ PEBs in public and private spheres. By analysing a Taiwan Social Change Survey data, we find that the willingness to sacrifice for the environment shows a significant mediating effect on the relationships between citizens’ PEBs and most public values, government, and environmental determinants. The results also demonstrate how citizens’ PEBs in the public sphere differ from those in the private sphere. Implications for theory and practice are addressed.

Published: August 2021

AbstractObjectivesTo compare patterns of technological adoption of minimally invasive surgery for radical prostatectomy across the United States and England.Data SourcesWe examine radical prostatectomy in the United States and England between 2005 and 2017, using de‐identified administrative claims data from the OptumLabs Data Warehouse in the United States and the Hospital Episodes Statistics in England.Study DesignWe conducted a longitudinal analysis of robotic, laparoscopic, and open surgery for radical prostatectomy. We compared the trends of adoption over time within and across countries. Next, we explored whether differential adoption patterns in the two health systems are associated with differences in volumes and patient characteristics. Finally, we explored the relationship between these adoption patterns and length of stay, 30‐day readmission, and urology follow‐up visits.Data CollectionOpen, laparoscopic, and robotic radical prostatectomies are identified using Office of Population Censuses and Surveys Classification of Interventions and Procedures (OPCS) codes in England and International Classification of Diseases ninth revision (ICD9), ICD10, and Current Procedural Terminology (CPT) codes in the United States.Principal FindingsWe identified 66,879 radical prostatectomies in England and 79,358 in the United States during 2005–2017. In both countries, open surgery dominates until 2009, where it is overtaken by minimally invasive surgery. The adoption of robotic surgery is faster in the United States. The adoption rates and, as a result, the observed centralization of volume, have been different across countries. In both countries, patients undergoing radical prostatectomies are older and have more comorbidities. Minimally invasive techniques show decreased length of stay and 30‐day readmissions compared to open surgery. In the United States, robotic approaches were associated with lower length of stay and readmissions when compared to laparoscopic.ConclusionsRobotic surgery has become the standard approach for radical proctectomy in the United States and England, showing decreased length of stay and in 30‐day readmissions compared to open surgery. Adoption rates and specialization differ across countries, likely a product of differences in cost‐containment efforts.
COVID‐Apps: Misdirecting Public Health Attention in a Pandemic
Authors: Erikson Susan 
Published: August 2021

AbstractWhen there is no vaccine for a disease, ‘Test, Trace, Treat/Isolate’ is the public health go‐to directive. During the COVID‐19 pandemic, mobile phone apps are designed to improve on this. But COVID‐apps have not been effective as a public health tool. Countries spend millions to develop them, yet they have been shown to have terrible return on investment. This commentary explores why COVID‐apps are generally championed and provides three brief case studies (Germany, Sierra Leone, Canada) of non‐app public health success. In conclusion, I argue that we need to get our public health care priorities straight: Better and more testing; increased investment in manual contact tracing and treatments; hospitalization when necessary; and wrap‐around care – assistance with groceries, cleaning, child‐ or eldercare responsibilities, telehealth doctor appointment hookups – for sick people in home isolation.

Abstract

Light‐level geolocators are popular bio‐logging tools, with advantageous sizes, longevity and affordability. Biologists tracking seabirds often presume geolocator spatial accuracies between 186 and 202 km from previously innovative, yet taxonomically, spatially and computationally limited, studies. Using recently developed methods, we investigated whether assumed uncertainty norms held across a larger‐scale, multispecies study.

We field‐tested geolocator spatial accuracy by synchronously deploying these with GPS loggers on scores of seabirds across five species and 11 Mediterranean Sea, east Atlantic and south Pacific breeding colonies. We first interpolated geolocations using the geolocation package FLightR without prior knowledge of GPS tracked routes. We likewise applied another package, probGLS, additionally testing whether sea‐surface temperatures could improve route accuracy.

Geolocator spatial accuracy was lower than the ~200 km often assumed. probGLS produced the best accuracy (mean ± SD = 304 ± 413 km, n = 185 deployments) with 84.5% of GPS‐derived latitudes and 88.8% of longitudes falling within resulting uncertainty estimates. FLightR produced lower spatial accuracy (408 ± 473 km, n = 171 deployments) with 38.6% of GPS‐derived latitudes and 23.7% of longitudes within package‐specific uncertainty estimates. Expected inter‐twilight period (from GPS position and date) was the strongest predictor of accuracy, with increasingly equatorial solar profiles (i.e. closer temporally to equinoxes and/or spatially to the Equator) inducing more error. Individuals, species and geolocator model also significantly affected accuracy, while the impact of distance travelled between successive twilights depended on the geolocation package.

Geolocation accuracy is not uniform among seabird species and can be considerably lower than assumed. Individual idiosyncrasies and spatiotemporal dynamics (i.e. shallower inter‐twilight shifts by date and latitude) mean that practitioners should exercise greater caution in interpreting geolocator data and avoid universal uncertainty estimates. We provide a function capable of estimating relative accuracy of positions based on geolocator‐observed inter‐twilight period.

Published: August 2021

AbstractThe effects of alkaline pH on the size and surface characteristics of gutta‐percha were studied. Forty ProTaper Universal‐F2 gutta‐percha cones (GPC) were stored individually for 8‐weeks. GPC were distributed into 2 groups (n = 20) based on the storage solutions’ pH (pH7, pH12). The GPC volume was measured after 1,2,3,4 and 8‐weeks using water displacement method and compared to the baseline volume. The surfaces of representative GPCs were analysed using Raman spectroscopy and assessed later using Scanning Electron Microscopy with Energy‐Dispersive X‐Ray Spectroscopy (EDS). Samples t test was used to compare the change in volume of GPC and a repeated measures Analysis of Variance (ANOVA) was used to compare the effects of storage durations. After 8‐weeks, GPCs aged in high‐pH exhibited significant drop in their volume (16%) compared with GPCs aged in water (2.5%). The surface of GPCs stored in water or high‐pH both demonstrated structural and chemical alterations in comparison with non‐aged GPCs.
The effect of women's nutrition knowledge and empowerment on child nutrition outcomes in rural Ethiopia
Authors: Melesse Mequanint B. 
Published: August 2021

AbstractChild malnutrition remains widespread in Ethiopia. Women's nutrition knowledge and empowerment are emphasized as key impact pathways for nutrition‐sensitive programs and interventions. This paper examines effects of women's nutrition knowledge and empowerment on child nutrition outcomes using survey data from rural Ethiopia. Employing econometric strategies that account for potential endogeneity concerns, nutrition knowledge, and empowerment are found to have strong and significant effects on children's dietary diversity and stunting. Their interaction is significantly correlated only with stunting, perhaps suggesting the importance of the interaction between nutrition knowledge and empowerment for long‐term nutrition outcomes. A disaggregated analysis of empowerment reveals that empowering women in household agricultural decisions and increasing their access to and control of economic resources are more promising for improving child nutrition. Overall, the findings suggest that efforts targeting to improve child nutrition in Ethiopia need to be complemented by efforts to improve women's nutrition knowledge and empowerment.

AbstractObjectivesTo investigate dementia knowledge within a rural Australian general public cohort and understand demographic predictors of knowledge in this population.DesignA cross‐sectional study comprising quantitative surveys.Setting321 participants were recruited from the Tasmanian general public (February‐September 2017).Participants28% of participants were from remote or outer regional postcodes; the remainder were from inner regional areas. The median age was 46 years; 35% were male. 30% had participated in prior dementia education, 29% had worked with people living with dementia, and 23% had no identified personal experience of people living with dementia.InterventionsNo interventions were conducted as part of this study.Main outcome measuresDementia knowledge was assessed using the Dementia Knowledge Assessment Scale. Demographic variables were also collected.ResultsMean dementia knowledge was moderate and participants scored highest on the care considerations subscale. Those with personal experience with a person living with dementia scored significantly higher on all subscales, and overall, than those without. Dementia education, general education, and previous work, care or close relationship with people living with dementia were all significant predictors in a regression model explaining nearly a third of the variance in overall dementia knowledge.ConclusionWhile personal experience of dementia improves knowledge of the condition, dementia education is the most important predictor. Deficits identified in knowledge of risk factors, and incomplete knowledge about aspects important to quality care, suggest a need for further education for the general public, particularly in the light of the rising prevalence of dementia in ageing rural populations.

AimsCarbamazepine (CBZ) is one of the most common causative drugs of severe cutaneous adverse drug reactions (SCARs) including Stevens–Johnson syndrome (SJS), toxic epidermal necrolysis (TEN) and drug reactions with eosinophilia and systemic symptoms. Although genetic polymorphisms of the human leucocyte antigens (HLA) are well recognized key elements for the susceptibility to CBZ‐induced SCARs, some evidence suggest that polymorphisms of microsomal epoxide hydrolase 1 (EPHX1) may also contribute to the risk of these SCARs. This study investigated the association between the HLA and EPHX1 polymorphisms on CBZ‐induced SCARs in large sample sizes and well‐defined SCARs patients.MethodsNinety‐one CBZ‐induced SCARs Thai patients and 144 CBZ‐tolerant patients were enrolled in the study. The genotypes of HLA‐A, HLA‐B and EPHX1 were determined.ResultsOnly 2 HLA alleles including HLA‐B*15:02 and HLA‐A*24:07 were statistically significant association with CBZ‐induced SJS/TEN. The highest risk was observed in patients with HLA‐B*15:02 allele (OR = 44.33, 95% confidence interval = 20.24–97.09, corrected P‐value = 6.80 × 10−29). Moreover, HLA‐B75 serotypes were significantly associated with CBZ‐induced SJS/TEN groups with an odds ratio of 81.00 (95% confidence interval = 32.39–202.56, corrected P‐value = 3.84 × 10−34). There is no association between EPHX1 c.337 T > C polymorphism and all phenotypes of CBZ‐induced SCARs.ConclusionThe HLA‐B*15:02 allele is the strongest genetic marker for the prediction of SJS/TEN induced by CBZ in Thai population. Screening for other alleles in the HLA‐B75 serotype increases sensitivity for prediction of a life‐threatening SCARs caused by CBZ.

AbstractAimsThis follow‐up study aimed to examine the 8‐year efficacy and safety of subthalamic nucleus (STN) deep brain stimulation (DBS) for patients with Parkinson's disease (PD) in southern China.MethodsThe follow‐up data of 10 patients with PD undergoing STN‐DBS were analyzed. Motor symptoms were assessed before and 1, 3, 5, and 8 years after the surgery with stimulation‐on in both off‐medication (off‐med) and on‐medication (on‐med) status using the Unified Parkinson's disease Rating Scale Part III. The quality of life was assessed using the 39‐item Parkinson's Disease Questionnaire. The sleep, cognition, and emotion were evaluated using a series of nonmotor scales. Levodopa equivalent daily dose (LEDD) and stimulation parameters were recorded at each follow‐up.ResultsThe motor symptoms were improved by 50.9%, 37.7%, 36.7%, and 37.3% in 1, 3, 5, and 8 years, respectively, in the off‐med / stimulation‐on status compared with the baseline. The quality of life improved by 39.7% and 56.1% in 1 and 3 years, respectively, but declined to the preoperative level thereafter. The sleep, cognition, and emotion were mostly unchanged. LEDD reduced from 708.1 ± 172.5 mg to 330 ± 207.8 mg in 8 years. The stimulation parameters, including amplitude, pulse width, and frequency, were 2.77 ± 0.49 V, 71.3 ± 12.8 μs, and 121.5 ± 21 Hz, respectively, in 8 years.ConclusionLong‐term therapeutic efficacy of STN‐DBS could be achieved even with relatively low stimulation intensity and medication dosage for PD patients in southern China. Motor improvement and medication reduction were maintained through the 8‐year follow‐up, but improvement in quality of life lasted for only 3 years. No definite changes was found in nonmotor symptoms after STN‐DBS.

AbstractAimA diverting ileostomy is typically performed to divert intestinal contents in high‐risk colorectal anastomoses. Ileostomy closure is associated with high rates of postoperative Clostridium difficile infection (CDI). Risk factors for the development of CDI are unclear; however, a correlation has been observed with delayed closure. This study aimed to assess the odds of developing CDI in patients who had a delay to reversal of ileostomy, compared to those who had no delay.MethodsA retrospective cohort study was conducted of patients undergoing reversal of ileostomy between 2010 and 2019 at a single tertiary centre. A delay to reversal of ileostomy was defined if the procedure was performed at >365 days following the index procedure. CDI was defined as the presence of Clostridium difficile toxin associated with diarrhoea. Univariable logistic regression analysis was performed to estimate odds of CDI for each covariable, comparing patients who had a delay to reversal of ileostomy with those who did not. Multivariable logistic regression analysis was used to adjust for the potential confounding effects of covariables.ResultsOf 195 patients, 11 (5.6%), developed postoperative CDI. Multivariable analysis showed that delay to reversal of ileostomy was associated with a nearly 7‐fold increase in odds of CDI (OR = 6.95, CI: 1.06–81.6; p‐value = 0.03).ConclusionA delay to reversal of ileostomy of >365 days was associated with a higher incidence of CDI postoperatively. Careful consideration should be given to the timing of reversal and appropriate preoperative counselling of patients.
