Authors: G.R. Gnaneshwari , Hema M.S. , Lingareddy S.C. 
Published: August 2021

Purpose
Pervasive computing environment allows the users to access the services anywhere and anytime. Due to the dynamicity, mobility, security, heterogeneity, and openness have become a major challenging task in the Pervasive computing environment. To solve the security issues and to increase the communication reliability, an authentication-based access control approach is developed in this research to ensure the level of security in the Pervasive computing environment.

Design/methodology/approach
This paper aims to propose authentication-based access control approach performs the authentication mechanism using the hashing, encryption, and decryption function. The proposed approach effectively achieves the conditional traceability of user credentials to enhance security. Moreover, the performance of the proposed authentication-based access control approach is estimated using the experimental analysis, and performance improvement is proved using the evaluation metrics. It inherent the tradeoff between authentication and access control in the Pervasive computing environment. Here, the service provider requires authorization and authentication for the provision of service, whereas the end-users require unlinkability and untraceability for data transactions.

Findings
The proposed authentication-based access control obtained 0.76, 22.836 GB, and 3.35 sec for detection rate, memory, and time by considering password attack, and 22.772GB and 4.51 sec for memory and time by considering without attack scenario.

Originality/value
The communication between the user and the service provider is progressed using the user public key in such a way that the private key of the user can be generated through the encryption function.
Addressing the higher education for sustainable development agenda at the College of Open and Distance Learning, St. Mary’s University, Ethiopia: opportunities and challenges
Authors: Tamrat Wondwosen 
Published: August 2021

Purpose
This study aims to assess the extent to which sustainable development practices are prevalent at the College of Open and Distance Learning (CODL), St. Mary’s University, Ethiopia. The assessment focused on identifying the college’s inclusion of the sustainable development agenda in its policy statements, various functions and practices.

Design/methodology/approach
The study adopted a mixed-method approach and used a case study in its design. Data were generated from a standard survey questionnaire, adopted from the unit-based sustainability assessment tool (Togo and Lotz-Sisitka, 2009), a semi-structured interview and documentary evidence.

Findings
The findings revealed that CODL has limited involvement in sustainability issues despite relevant policy directions set at national and institutional levels. Current engagement patterns are limited to teaching, course provision and a few areas of operations and management while a serious gap has been noted as regard the two core functional areas of research and community service which happen to be neglected.

Research limitations/implications
This study was based on a single CODL, albeit an institution with a long history of offering distance education in Ethiopia. Despite its contribution to an understanding of how sustainability issues are addressed in the context of Africa in general and Ethiopia in particular, the generalizability of the findings to other similar institutions is limited.

Originality/value
There is very little research in Africa as regard the involvement of higher education institutions in promoting the issues of sustainability in general and distance education providers in particular. In addition to addressing this gap, the study suggests the need for distance education institutions to improve their mapping strategies and respond to the greater concerns of sustainable development.
Evaluation of the tribological performance of the green hBN nanofluid on the friction characteristics of AISI 316L stainless steel
Authors: Akincioğlu Sıtkı , Şirin Şenol 
Published: August 2021

Purpose
The purpose of this study is to investigate the effect of new green hexagonal boron nitride (hBN) nanofluid on AISI 316L stainless friction coefficient, wear resistance and wear using a ball on disc tester.

Design/methodology/approach
Nanofluids were prepared by adding hBN nanoparticles with two-step method to the vegetable-based oil at 0.50 vol%. Before the experiments, hBN nanofluid viscosity, pH and thermal conductivity specifications were determined. Friction tests of AISI 316L stainless steel were performed under 2 N, 5 N and 8 N loads at 400 rpm using a ball-on-disc test device under dry, oil and hBN conditions. Coefficient of friction, wear profile, surface integrity and wear mechanisms were chosen as performance criteria.

Findings
The friction coefficient values obtained under the oil and hBN test conditions with the 8 N load were, respectively, 72.46% and 77.64% lower than those obtained under dry test conditions. hBN nanofluid performed better on surface topography, and especially wear, compared to the dry and oil test conditions.

Practical implications
The aim of this study was to determine the best tribological performance of the hBN nanofluid on AISI 316L stainless steel used in orthopedic applications.

Originality/value
The paper is a study investigating the effect of hBN nanoparticle additive in vegetable-based oil on friction and wear performance of AISI 316L stainless steel. It is an original paper and is not published elsewhere.
Dynamic pricing and coupon promotion strategies in a dual-channel supply chain based on differential game
Authors: Li Zonghuo , Yang Wensheng , Si Yinyuan 
Published: August 2021

PurposeThis paper investigates a dual-channel supply chain in which a manufacturer offers coupons in the online channel and the retailer in the offline channel. The optimal pricing and coupon promotion policies are explored, and the brand image under different promotion scenarios is studied.Design/methodology/approachThree differential game models, namely no coupon is offered, coupons offered by the manufacturer and coupons offered by the retailer, are constructed.FindingsThe results show that the manufacturer and retailer intend to conduct coupon promotions under a large coupon redemption rate. Coupon promotion derives a higher price and profit for the issuers, and the manufacturer can free-ride on the retailer's coupon promotion. The retailer's profit in the retailer-promotion scenario may be lower than that in the manufacturer-promotion scenario in some special conditions. Besides, price, coupon face value, brand image and profit increase over time. After multiple cycles game, the operational strategy evolves to an optimal equilibrium status.Originality/valueThis paper provides guidance and advice for dual-channel supply enterprises to implement joint pricing and coupon promotion strategies under multiple sales seasons.
On the fuzzy interval equal surplus sharing solutions
Authors: Özcan İsmail , Alparslan Gök Sırma Zeynep 
Published: August 2021

PurposeThis paper deals with cooperative games whose characteristic functions are fuzzy intervals, i.e. the worth of a coalition is not a real number but a fuzzy interval. This means that one observes a lower and an upper bound of the considered coalitions. This is very important, for example, from a computational and algorithmic viewpoint. The authors notice that the approach is general, since the characteristic function fuzzy interval values may result from solving general optimization problems.Design/methodology/approachThis paper deals with cooperative games whose characteristic functions are fuzzy intervals, i.e. the worth of a coalition is not a real number but a fuzzy interval. A situation in which a finite set of players can obtain certain fuzzy payoffs by cooperation can be described by a cooperative fuzzy interval game.FindingsIn this paper, the authors extend a class of solutions for cooperative games that all have some egalitarian flavour in the sense that they assign to every player some initial payoff and distribute the remainder of the worth v(N) of the grand coalition N equally among all players under fuzzy uncertainty.Originality/valueIn this paper, the authors extend a class of solutions for cooperative games that all have some egalitarian flavour in the sense that they assign to every player some initial payoff and distribute the remainder of the worth v(N) of the grand coalition N equally among all players under fuzzy uncertainty. Examples of such solutions are the centre-of-gravity of the imputation-set value, shortly denoted by CIS value, egalitarian non-separable contribution value, shortly denoted by ENSC value and the equal division solution. Further, the authors discuss a class of equal surplus sharing solutions consisting of all convex combinations of the CIS value, the ENSC value and the equal division solution. The authors provide several characterizations of this class of solutions on variable and fixed player set. Specifications of several properties characterize specific solutions in this class.

Published: August 2021

PurposeThe goal of this study is to examine how tweets containing distinct emotions (i.e., emotional tweets) and different information types (i.e., misinformation, corrective information, and others) are prevalent during the initial phase of mass shootings and furthermore, how users engage in those tweets.Design/methodology/approachThe researchers manually coded 1,478 tweets posted between August 3–11, 2019, in the immediate aftermath of the El Paso and Dayton mass shootings. This manual coding approach systematically examined the distinct emotions and information types of each tweet.FindingsThe authors found that, on Twitter, misinformation was more prevalent than correction during crises and a large portion of misinformation had negative emotions (i.e., anger, sadness, and anxiety), while correction featured anger. Notably, sadness-exhibiting tweets were more likely to be retweeted and liked by users, but tweets containing other emotions (i.e., anger, anxiety, and joy) were less likely to be retweeted and liked.Research limitations/implicationsOnly a portion of the larger conversation was manually coded. However, the current study provides an overall picture of how tweets are circulated during crises in terms of misinformation and correction, and moreover, how emotions and information types alike influence engagement behaviors.Originality/valueThe pervasive anger-laden tweets about mass shooting incidents might contribute to hostile narratives and eventually reignite political polarization. The notable presence of anger in correction tweets further suggests that those who are trying to provide correction to misinformation also rely on emotion. Moreover, our study suggests that displays of sadness could function in a way that leads individuals to rely on false claims as a coping strategy to counteract uncertainty.Peer reviewThe peer review history for this article is available at: https://publons.com/publon/10.1108/OIR-03-2021-0121/
A fresh scientific look at transfer and persistence: From a materials science and tribology perspective
Authors: Aberle Michael G. , Kobus Hilton , Robertson James , O'Driscoll Caroline , Hoogewerff Jurian A. 
Published: August 2021

AbstractKnowledge of the mechanisms governing transfer, persistence, and recovery of trace evidence, together with background prevalence in the population of interest, and other task relevant information, is key for the forensic interpretation and reconstruction of what happened at the activity level. Up to now, this informational “toolkit” has largely been developed through empirical forensic studies on specific trace materials such as glass, textile fibers, and soil. Combined with the identified systemic siloing between disciplines, while valuable, such research tends to be very material‐dependent, introducing specific parameters and interpretations that may have actually impeded the recognition of underlying foundational factors applicable to most material types. In Australia, there has been a renewed interest in developing a discipline‐independent framework for the interpretation and/or reconstruction of trace evidence to interpret specific circumstances in casework. In this paper, we present a discipline agnostic “way of thinking” that has been anchored in foundational science underpinning the trace evidence discipline. Physical and mechanical material properties such as material geometry and surface topography, strength, stiffness, and hardness collectively influence contact interactions through underlying friction, wear, and lubrication cause and effect mechanisms. We discuss how these fundamental factors and parameters stemming from materials science and tribology may be adopted and adapted by forensic practitioners and researchers to contribute to a better understanding of transfer, persistence, and recovery mechanisms irrespective of evidence discipline and material type. Examples are provided to demonstrate the practical significance to real‐life casework and academic research.

Published: August 2021

AbstractBackgroundFibrinogen concentrate is used clinically to improve hemostasis in bleeding patients. We investigated and compared the efficacy of three commercially available fibrinogen concentrates to improve clot strength in blood samples from cardiac surgery patients.ObjectivesPostoperative blood samples were collected from 23 cardiac surgery patients. Samples were each divided into four vials, each supplemented with 1.125 mg of fibrinogen of one of three fibrinogen concentrates (RiaSTAP®, Fibryga®, FibCLOT®), or placebo. The fibrinogen dose corresponded to 2.5 g per 70 kg of body weight. Clot strength after supplementation was assessed in duplicate with rotational thromboelastometry (ROTEM®) using FIBTEM maximum clot firmness, EXTEM clot formation time, and maximum clot firmness assays.ResultsIn vitro fibrinogen concentrate supplementation of the samples resulted in higher plasma fibrinogen concentrations and improved clot strength with all three concentrates. Supplementation with FibCLOT increased FIBTEM maximum clot firmness (+46% [25th–75th percentile 35–55] compared to placebo) significantly more than did supplementation with Fibryga (+26% [21–35]) and RiaSTAP (+29% [22–47], p < .001). FibCLOT supplementation also shortened EXTEM clot formation time and increased EXTEM maximum clot firmness to a greater extent than did the other concentrates (both p < .001).ConclusionsAt the selected dose, FibCLOT was more effective than Fibryga and RiaSTAP in restoring clot strength in postoperative blood samples from cardiac surgery patients. These results may have implications for the choice of fibrinogen concentrate and dosing.

Published: August 2021

AbstractBackgroundEmerging evidence supports a strong association between the skin and the gut. The association between seborrheic dermatitis (SD) and peptic ulcer disease (PUD) was largely unknown. This study aimed to investigate the association of SD and PUD.MethodsThis nationwide population‐based cohort study was conducted using the Taiwan's National Health Insurance Research Database. A total of 19 445 participants was recruited. Each patient with a diagnosis of incident SD was matched to four patients without SD using propensity scores based on age, gender, index year, insurance amount, urbanisation level, Charlson comorbidity index (CCI), the presence of comorbidities and medication use. The primary endpoint was the development of incident PUD. Hazard ratios (HRs) and corresponding 95% confidence intervals (CIs) for PUD occurrence in relation to the presence of SD were calculated.ResultsOverall, patients with SD had a significantly higher risk for incident PUD than those without SD in both univariable (crude HR = 1.60, 95% CI 1.38–1.86, P < 0.001) and multivariable (adjusted HR = 1.58, 95% CI 1.36–1.83, P < 0.001) Cox proportional hazard regression models. Kaplan–Meier analysis indicated that the cumulative incidence of PUD was consistently higher in individuals with SD than those without SD (log‐rank test, P < 0.001). A higher risk of PUD was also found in individuals with SD than those without SD in all stratified analyses by age, gender, CCI and follow‐up time.ConclusionPatients with SD may have a higher risk for incident PUD. Further studies are warranted to validate our findings.

AbstractA 16‐y‐old Japanese female was referred to our hospital with a suspicion of infected retroperitoneal cyst. Abdominal CT MRI revealed a 38‐mm diameter retroperitoneal cyst under the left diaphragm. Because a retroperitoneal bronchogenic cyst was suspected, total resection was planned. In addition, preoperative 3D reconstruction using multidetector CT provided a detailed location of the lesion. Based on the anatomical position, we decided that single‐incision laparoscopic surgery with an anterior approach through the umbilicus would be the optimal choice. The lesion was completely resected without intraoperative complications. Histopathological examination confirmed the diagnosis of bronchogenic cyst. Postoperatively, the surgical wound became completely unnoticeable, and there was no incisional hernia or cyst recurrence at the 2‐y follow‐up.
Zero‐alcohol beverages: Harm‐minimisation tool or gateway drink?
Authors: Miller Mia , Pettigrew Simone , Wright Cassandra J. C. 
Published: August 2021

AbstractZero‐alcohol beverages, classified as products containing ≤0.5% alcohol by volume, are becoming increasingly popular. These beverages may contribute to alcohol harm reduction efforts if drinkers switch to them from regular strength beverages. However, there is currently a lack of evidence to support a substitution hypothesis, particularly as alcohol companies frequently market zero‐alcohol beverages as drinks to consume in new locations, such as in the workplace, or by previously non‐drinking groups, such as pregnant women. Additionally, zero‐alcohol beverages are currently available for sale in supermarkets by all consumers, including minors. This is problematic as there is a lack of evidence around what impact consumption of zero‐alcohol beverages in youth might have on social norms and initiation of alcohol consumption. In this commentary, we explore the existing evidence on zero‐alcohol beverages and their impact on drinking behaviours, concluding that a current paucity of knowledge makes developing evidence‐based policy a challenge. As such, substantial research efforts are required to inform policies regulating the availability and marketing of zero‐alcohol beverages in Australia.

Published: August 2021

AbstractObjectiveThis study aimed to explore patients' experiences of their involvement in the design and delivery of interprofessional education interventions focussing on mental ill‐health for students studying in undergraduate healthcare and healthcare‐related programmes.DesignA qualitative methodology using a Grounded Theory approach was used to undertake an iterative series of focus groups with members of a university's Patient, Carer and Public Involvement (PCPI) Group who have a history of mental ill‐health and were involved in the development and delivery of educational interventions for students on undergraduate healthcare and healthcare‐related programmes. Their experiences of being involved in teaching and learning activities, collaboration with academic staff and integration into the academic faculty were explored. Constant comparative analysis facilitated the identification and prioritisation of salient themes.ResultsFive salient inter‐related themes emerged from the data: (1) reduced stigma and normalisation of experience of illness; (2) enhanced self‐worth; (3) improved well‐being; (4) community and connection; and (5) enduring benefits.ConclusionsA supportive university community and a designated academic PCPI co‐ordinator facilitate a supportive environment for patients and carers to develop as educators, contribute to the training of future healthcare professionals and improve their own personal well‐being. Appropriately resourced and well‐supported initiatives to integrate patients, carers and the public into the functions of an academic faculty can result in tangible benefits to individuals and facilitate meaningful and enduring connections between the university and the wider community within which it is situated.Patient and Public InvolvementPatients have been involved in the design of the teaching and learning initiatives that this study was primarily focused on. Patients were given autonomy in determining how their experiences should be incorporated into teaching and learning experiences.

AbstractBackgroundLichen planus (LP) is a chronic inflammatory disorder usually occurring in middle‐aged adults. Data are scarce in the pediatric population.ObjectiveTo describe the patients’ characteristics, clinical presentation, and management of pediatric LP.MethodsA systematic literature review of pediatric LP was performed in the Medline and Cochrane databases up to February 1, 2020. Demographic and clinical data were extracted for analysis, in addition to laboratory and histology findings, treatments used, and response to treatment. LP pemphigoides (LPP) was further pooled for a subcategory analysis.ResultsOne hundred and sixty‐four articles were included representing 985 patients. The most common country of origin was India. The most common clinical signs were flat‐topped papules (51%); the linear variant was present in 9%. Oral involvement was present in 22%. The most commonly used treatment was topical corticosteroids followed by systemic corticosteroids. The mean duration of treatment was 124.4 days. LPP patients had a short disease duration before diagnosis (4.1 months, P < 0.001) and failed previous treatment more frequently (P < 0.001). Systemic corticosteroids were more often prescribed in this subgroup (75%, P < 0.001) with more recurrence after treatment (31%, P = 0.048).LimitationsLack of randomized controlled studies, in addition to publication bias.ConclusionIn children, LP had a wide polymorphous clinical presentation, and the reported cases were mostly from India. The linear variant was more common and the oral mucosa was less affected in children. LPP, a rare subtype in children, was treated with systemic corticosteroids and recurred more frequently.
