Published: July 2021

PurposeAlthough there have been considerable discussions on the business value of adopting blockchain in supply chains, it is unclear whether such blockchain-enabled supply chains (BESCs) can help firms mitigate the negative impact resulting from the recent COVID-19 pandemic. This study aims to answer this important question.Design/methodology/approachThe authors conduct an event study to quantify the financial effects of the COVID-19 pandemic and compare the differences in such effects between treatment firms that have adopted BESCs and matched control firms that have not adopted BESCs. The authors also perform a regression analysis to examine how the role of BESCs in mitigating COVID-19's negative impact varies across firms with different levels of supply chain leanness and complexity. The analysis is based on 88 treatment firms and 88 matched control firms, all of which are publicly listed on the US stock markets.FindingsThe test results suggest that although both the treatment and control firms are negatively affected by the COVID-19 pandemic, the effect is less negative for the treatment firms compared to the control firms, demonstrating the role of BESCs in mitigating the negative impact caused by the COVID-19 pandemic. Moreover, the mitigating role of BESCs is more pronounced for firms with lean and complex supply chains.Originality/valueThis study is among the first to provide empirical evidence on the mitigating role of BESCs during the COVID-19 pandemic, highlighting the importance of adopting blockchain in supply chains with high uncertainties and disruption risks.

Published: July 2021

Purpose
This paper aims to develop a Mini-Tribometer for in-situ observation of subsurface.

Design/methodology/approach
To observe the change of the microstructure during wear in real time, an in-situ observation mini-tribometer was developed according to the requirements of the basic frictional experiments and carried out the verification experiments.

Findings
The subsurface images and the tribological data obtained from the mini-tribometer clearly show that the graphite in the matrix moves to the surface and takes part in lubrication mainly in the form of extrusion and peeling off, and the migration of graphite in the copper-based composite to the frictional interface to act as lubricant and to result in the decrease of the friction coefficient. The experimental results of the developed tribometer are accurate, which can provide important references for further research on the wear mechanism of materials.

Originality/value
The developed in-situ observation mini-tribometer can be used to observe the dynamic wear mechanism of the frictional pairs, which is very important for optimization of material design and tribological performances.

Published: July 2021

PurposeThe purpose of this paper is to investigate the impact of buyer-seller interpersonal interactions on the purchase intention of buyers, incorporating swift guanxi as a mediator.Design/methodology/approachBased on survey data obtained from 336 Taobao Live users, PLS techniques were used to test hypotheses.FindingsSwift guanxi exists in buyer-seller interactions and matters, as it drives buyers' purchase intention in live stream shopping. Perceived expertise, perceived similarity and perceived likeability are found to be the three essential interpersonal interaction factors promoting the formation of swift guanxi. Perceived familiarity is also found to be significant but to a lesser extent. In addition, all these interpersonal interaction factors are found to significantly affect purchase intention through the mediation of swift guanxi.Originality/valueSwift guanxi has been less explored in live stream shopping. This study takes the lead in empirically examining the mediating role of swift guanxi in the relationship between interpersonal interaction factors and purchase intention and offers a description of key buyer-seller interpersonal interaction factors (perceived expertise, perceived similarity and perceived likeability), thereby helping to extend the swift guanxi literature in social commerce.

Published: July 2021

Purpose
The purpose of this study is to conduct a rigorous systematic literature review and present a summary of building systems and technologies that can be used to mitigate the spread of airborne viruses. With the recent outbreak of COVID-19, occupants’ health and indoor air quality (IAQ) have become a critical issue for facility managers to maintain the full functionality of the buildings. An improved understanding of these available systems will help facility managers and building owners to protect the health and safety of building occupants.

Design/methodology/approach
The PRISMA protocol was used for defining the literature search methodology. The concept mapping technique was used for determining the keywords. The keywords were then used to search for relevant articles using the Scopus database and Google Scholar. A thorough bibliometric analysis and qualitative analysis were conducted for the selected publications.

Findings
It was found that sensor technologies, botanical air-filtration systems and artificial intelligence could be used to effectively monitor and improve IAQ. In addition, natural ventilation is one of the low-cost and effective methods of reducing contaminants from the indoor air. Computational fluid dynamic modeling can be used to understand the flow of virus particles within the building through the heating, ventilation and air-conditioning (HVAC) system. Several changes to the HVAC system are also discussed.

Originality/value
This study contains a diversity of methods from the existing literature that were systematically selected to present the state-of-the-art building systems and technologies that can effectively improve IAQ. The researchers plan to follow up on the findings of this research and will conduct an empirical study to assess its impact on IAQ.
Do eReferral, eWOM, familiarity and cultural distance predict enrollment intention? An application of an artificial intelligence technique
Authors: Oday Akile , Ozturen Ali , Ilkan Mustafa , Abubakar A. Mohammed 
Published: July 2021

PurposeLittle empirical attention has been paid to the effects of electronic word-of-mouth (eWOM), electronic referral (eReferral), familiarity and cultural distance on behavioral outcomes, especially within the context of educational tourism. Based on the social network theory, this paper aims to explore the effects of eReferral, eWOM, familiarity and cultural distance on enrollment intention.Design/methodology/approachSurvey data (n= 931) were obtained from educational tourists using a judgmental sampling technique. Linear modeling and artificial intelligence (i.e. artificial neural network [ANN]) techniques were used for training and testing the proposed associations.FindingsThe results suggest that eReferral, eWOM, familiarity and cultural distance predict intention to enroll both symmetrically (linear modeling) and asymmetrically (ANN). The asymmetric modeling possesses greater predictive validity and relevance.Originality/valueThis study contributes theoretically and methodologically to the management literature by validating the proposed relationships and deploying contemporary methods such as the ANN. Implications for practice and theory are discussed.
Cyberbullying detection from tweets using deep learning

Published: July 2021

PurposeWith the rise of social media platforms, an increasing number of cases of cyberbullying has reemerged. Every day, large number of people, especially teenagers, become the victim of cyber abuse. A cyberbullied person can have a long-lasting impact on his mind. Due to it, the victim may develop social anxiety, engage in self-harm, go into depression or in the extreme cases, it may lead to suicide. This paper aims to evaluate various techniques to automatically detect cyberbullying from tweets by using machine learning and deep learning approaches.Design/methodology/approachThe authors applied machine learning algorithms approach and after analyzing the experimental results, the authors postulated that deep learning algorithms perform better for the task. Word-embedding techniques were used for word representation for our model training. Pre-trained embedding GloVe was used to generate word embedding. Different versions of GloVe were used and their performance was compared. Bi-directional long short-term memory (BLSTM) was used for classification.FindingsThe dataset contains 35,787 labeled tweets. The GloVe840 word embedding technique along with BLSTM provided the best results on the dataset with an accuracy, precision and F1 measure of 92.60%, 96.60% and 94.20%, respectively.Research limitations/implicationsIf a word is not present in pre-trained embedding (GloVe), it may be given a random vector representation that may not correspond to the actual meaning of the word. It means that if a word is out of vocabulary (OOV) then it may not be represented suitably which can affect the detection of cyberbullying tweets. The problem may be rectified through the use of character level embedding of words.Practical implicationsThe findings of the work may inspire entrepreneurs to leverage the proposed approach to build deployable systems to detect cyberbullying in different contexts such as workplace, school, etc and may also draw the attention of lawmakers and policymakers to create systemic tools to tackle the ills of cyberbullying.Social implicationsCyberbullying, if effectively detected may save the victims from various psychological problems which, in turn, may lead society to a healthier and more productive life.Originality/valueThe proposed method produced results that outperform the state-of-the-art approaches in detecting cyberbullying from tweets. It uses a large dataset, created by intelligently merging two publicly available datasets. Further, a comprehensive evaluation of the proposed methodology has been presented.
Business process reengineering in health-care sector: application for the central sterilization unit
Authors: Dursun Mehtap , Fındık S. Sirin , Goker Nazli 
Published: July 2021

Purpose
In a rapidly changing environment, many health-care systems are forced to survive with rising costs and the need for proper resources utilization. To address the requirements for effective strategic planning, business process reengineering (BPR) is inevitable for health-care systems. This study aims to focus on the reengineering of central sterilization unit’s business processes to obtain performance improvement and efficiency. With the obtained new process design, it is expected to get standardization in all level of the central sterilization unit.

Design/methodology/approach
This paper presents a BPR method for modeling the system in health-care sector to improve the productivity of the sterilization process of surgical equipment. The case study is conducted in a large hospital in Istanbul, Turkey. First, “as-is” process is modeled and the problems are determined. Then, solution methods are developed and the target system (to-be process) is redesigned and the workflows of each phase are remodeled by using ARIS tool. Enterprise resource planning (ERP)-driven BPR is used to reengineer the current processes and the future processes are operated through the modeled ERP system. Finally, by using a statistical analysis, performance of the new process is compared with the existing process using the first data obtained from the case hospital.

Findings
In many sterilization services, the control procedures are rarely used. Thus, an ERP solution is developed to automate sterilization tasks and track down the information flow. With the ERP solution, it is possible to track in which dates, where and by whom the items are processed. On the other hand, in the sterilization process, the sets are used efficiently according to the last sterile dates of the items. Also, with the ERP system, it is possible to reduce unnecessary paper usage and this gives the hospitals the opportunity to be more ecological and sustainable. As a result, a centralized sterilization process with an IT support provides efficiency, economy and patient safety.

Originality/value
This study seeks for the potential benefits of an ERP implementation in health-care sector. As a result of this project, improvements in productivity, cost and quality are expected in sterilization processes because the new process design will bring automation, human-related error reduction and equipment tracking system. For this purpose, a business process management software is developed and implemented to the central sterilization unit so that the information flows more safely and the managers can track the results quickly by charts and reports.
Employees' dedication to working from home in times of COVID-19 crisis
Authors: Prodanova Jana , Kocarev Ljupco 
Published: July 2021

PurposeAs part of the COVID-19 preventive measures that have entirely impacted individuals' lives worldwide, remote work has been indicated as one of the most challenging aspects that have passed through great adaptation in the past months, highlighting the need for its better understanding. Following the fundamental theoretical frameworks of motivation, the authors argue that remote work tasks and the environment highly determine employees' productivity and satisfaction, which in turn influence their intention to continue working from home once the restrictions are relaxed.Design/methodology/approachData from 363 remote work employees were collected, indicating their personal experiences of working from home during COVID-19 quarantine. The analyses were carried out using partial least squares–structural equation modelling (PLS-SEM) methodology, employing the SmartPLS3 software.FindingsThe results reveal the possibility for reconciliation and the adequate remote work's flow as motivating, and the interruptions and technology-related anxiety as interfering impacts, in the process of achieving functional home office. However, although employees might be productive, it is not a sufficient condition for them to show an intention to continue working remotely after the COVID-19 pandemic is over, contrary to their satisfaction, which is found crucial for their future intentions.Originality/valueThe theoretical and practical implications of this study suggest several avenues for productive management of the transition to remote work, especially when the need is imposed urgently and an adequate selection of the most indispensable aspects for constructive working from home must be rapidly reached.

Authors: Rief Rachael , Clinkinbeard Samantha 
Published: July 2021

PurposeThe purpose of the study was to examine the relationship between officer perceptions of fit in their organization and stress (organizational and operational), overall job satisfaction and turnover contemplation (within the last 6 months).Design/methodology/approachThe authors used cross-sectional survey data from a sample of 832 officers from two Midwest police departments to examine the relationships between fit, stress and work-related attitudes.FindingsPerceived stress and organizational fit were strong predictors of overall job satisfaction and turnover contemplation; organizational fit accounted for the most variation in stress, satisfaction and turnover contemplation. Organizational stress partially mediated the relationship between organizational fit and job satisfaction and organizational fit and turnover contemplation.Research ImplicationsMore research is needed to identify predictors of organizational fit perceptions among police officers.Practical implicationsFindings indicate that agencies should pay close attention to the organizational culture and structure when trying to address issues of officer well-being and retention. Further, the person−environment framework can be a useful tool in examining police occupational outcomes.Originality/valueThe authors findings contribute to research on officer stress by exploring perceptions of organizational fit as a predictor of stress and unpackinghowofficer stress matters to important work outcomes, including job satisfaction and thoughts of turnover, by considering stress as a mediator between organizational fit and these work outcomes.

Authors: Laser Jan 
Published: July 2021

Purpose
The purpose of this paper is to examine the connections between vision statements, leadership and human resource management (HRM) to clarify what contribution HRM has to make in translating an organizational goal into a vision statement.

Design/methodology/approach
The importance of vision statements is explained. Empirical data are used to illustrate the failure of many companies to exploit the potential of a vision statement. Finally, the role of HRM in formulating a vision statement is discussed.

Findings
“Vision statement” is another term for primary organizational goal. Setting this primary goal is an indispensable task of leadership. If the vision statement is missing, HRM should remedy the situation.

Originality/value
The added value of this paper lies in explaining why vision statements are relevant for both leadership and HRM and the functions and leading role of HRM in actualizing the vision statement.

Published: July 2021

AbstractThe International Space Station (ISS) is a closed facility that orbits the earth carrying not only its crew but also microorganisms. We have participated in microbiota analysis projects for the Japanese Experiment Module KIBO (ISS; operations nomenclature: Microbe‐I, II, III, and IV) and were in charge of fungal screening. The interior of KIBO was sampled using swabs and microbe detection sheets (MDSs) for fungal detection. The dominant genera obtained by culture were Aspergillus and Penicillium. DNA analyses of the fungal biota using a clone library showed that KIBO was dominated by Malassezia, a fungal inhabitant of human skin. Three fungal species, Aspergillus sydowii, Penicillium palitans, and Rhodotorula mucilaginosa, which grew under microgravity in KIBO were observed under a field emission‐scanning electron microscope on the ground. No novel phenotypic characteristics were noted. The results of antifungal susceptibility testing of all isolates did not differ significantly from previous reports of corresponding fungi. In Microbe‐I (August 2009), MDSs were culture negative, while in the next stages the CFU of MDSs were 10 for Microbe‐II (February 2011), 24 for Microbe‐III (October 2012), and 151 for Microbe‐IV (February 2015). These results indicated that fungi inside KIBO are increasing and expanding over time, and therefore continuous surveillance is crucial.
Rite of passage for care leavers
Authors: Stead Helen 
Published: July 2021

AbstractThis article draws upon work undertaken individually with young people on the cusp of leaving care, focussing on the final therapy session. This is seen as a rite of passage where Fare Well is both “Goodbye” and a message to accompany them as they leave care. The work uses concepts from narrative therapy, in particular outsider witnessing and “co‐research” and general principles of collaborative therapy. Such approaches are used in combination with theories around the importance and development of attachment in children. I seek to demonstrate how developing therapy as a “Secure base/space” is key to engagement and encouraging change with such young people. After outlining the context of this work, each young person's “Fare Well” is discussed separately. The presence of a reflecting partner and accompanying adult is suggested as a way to assist successful engagement and a possible focus for future research.Practitioner points

Those practitioners working where session numbers are limited may need to be creative in ways to offer the pace and longevity of involvement necessary to gain the trust and engagement of young people in care.

A consistent adult, chosen by the young person, accompanying them in sessions, enhances engagement and promotes change in the network.

The reflecting process provides space for the young person grappling with understanding emotions to untangle and word those feelings.
