Authors: Kordzadeh Ali , Hoff Mekhola , Askari Alan , Parsa Ali D. 
Published: January 2022

ABSTRACTBackgroundThe aim of this study is to establish and evaluate whether the use of prophylactic antibiotics in the creation of any autogenous arteriovenous fistula in hemodialysis patients is indicated, evidence-based and/or recommended.MethodsA systematic review and meta-aggregation of the literature from 1966 to August 2016 in the English language in Medline, Scopus, Embase and Cochrane Library was conducted.ResultsThe search produced a total of n=94 articles. Following the application of the recruitment criteria in accordance to PRISMA one (n=1) article was found eligible with a population of n=611 patients undergoing autogenous fistula formation. A total of n=136 patients received prophylactic antibiotics with no incidence of surgical site infection (SSI). The reported incidence of SSI in the group of patients (n=475) that did not receive prophylactic antibiotics was 0.2% (n=1). The quality of the article was assessed by the Oxford Critical Appraisal Skills Programme (CASP) and their recommendation for practice was evaluated through National Institute for Health and Care Excellence (NICE).ConclusionThe first systematic review of the literature demonstrates that the current use of prophylactic antibiotics in the creation of any autogenous AVF is not evidence-based and further research in this area is highly advocated.

AbstractSerum hepatitis B virus (HBV) kinetics in urokinase-type plasminogen activator/severe combined immunodeficient (uPA-SCID) mice reconstituted with humanized livers from inoculation to steady state is highly dynamic despite the absence of an adaptive immune response. We developed a stochastic agent-based model that includes virion production cycles in individual infected human hepatocytes. The model was calibrated using a genetic algorithm approach with the serum HBV kinetics observed in mice inoculated with 108HBV genome equivalents and fit the data well when the following viral production parameters were assumed: (1) An eclipse phase lasting 5-50 hours and (2) a post-eclipse phase production rate that is based on increasing production cycles initially starting with a long production cycle of 1 virion per 20 hours that gradually reaches 1 virion per hour after approximately 3-4 days before virion production increases dramatically to reach to a steady state production rate of 4 virions per hour per cell. The model was then validated by showing it could accurately simulate the viral kinetics observed with lower HBV inoculation doses (104-107genome equivalents) in which similar, but delayed patterns were observed. Together, modeling suggests that it is the cyclic nature of the virus lifecycle combined with an initial slow but increasing rate of HBV production from each cell that plays a role in generating the observed multiphasic HBV kinetic patterns in humanized mice.

Authors: Mater Yasser , Kamel Mohamed , Karam Ahmed , Bakhoum Emad 
Published: January 2022

Purpose
Utilization of sustainable materials is a global demand in the construction industry. Hence, this study aims to integrate waste management and artificial intelligence by developing an artificial neural network (ANN) model to predict the compressive strength of green concrete. The proposed model allows the use of recycled coarse aggregate (RCA), recycled fine aggregate (RFA) and fly ash (FA) as partial replacements of concrete constituents.

Design/methodology/approach
The model is constructed, trained and validated using python through a set of experimental data collected from the literature. The model’s architecture comprises an input layer containing seven neurons representing concrete constituents and two neurons as the output layer to represent the 7- and 28-days compressive strength. The model showed high performance through multiple metrics, including mean squared error (MSE) of 2.41 and 2.00 for training and testing data sets, respectively.

Findings
Results showed that cement replacement with 10% FA causes a slight reduction up to 9% in the compressive strength, especially at early ages. Moreover, a decrease of nearly 40% in the 28-days compressive strength was noticed when replacing fine aggregate with 25% RFA.

Research limitations/implications
The research is limited to normal compressive strength of green concrete with a range of 25 to 40 MPa.

Practical implications
The developed model is designed in a flexible and user-friendly manner to be able to contribute to the sustainable development of the construction industry by saving time, effort and cost consumed in the experimental testing of materials.

Social implications
Green concrete containing wastes can solve several environmental problems, such as waste disposal problems, depletion of natural resources and energy consumption.

Originality/value
This research proposes a machine learning prediction model using the Python programming language to estimate the compressive strength of a green concrete mix that includes construction and demolition waste and FA. The ANN model is used to create three guidance charts through a parametric study to obtain the compressive strength of green concrete using RCA, RFA and FA replacements.
Tackling gender bias in equity crowdfunding: an exploratory study of investment behaviour of Latin American investors
Authors: Cicchiello Antonella Francesca Francesca , Kazemikhasragh Amirreza 
Published: January 2022

PurposeBelonging to the financial technologies’ companies, equity-based crowdfunding platforms offer investors the opportunity to become shareholders through the purchase of small equity stakes of new innovative ventures. This paper aims to investigate gender-related differences in the behaviour of investors in firms seeking equity financing in Latin America.Design/methodology/approachUsing a unique database, with combined information from different equity crowdfunding platforms in Brazil, Chile and Mexico, the authors study the population of 492 projects between 2013 and 2017. To analyse the relationship between investors’ gender-related differences and equity crowdfunding investment, this paper applies Poisson regression.FindingsResults suggest that the probability that an investor finances a firm is based on gender bias. Investors prefer firms led by entrepreneurs that are similar to them in terms of gender. Furthermore, the authors find evidence that both female and male investors are risk-averse and are more likely to invest in the equity of firms that are older and offer a higher percentage of equity. However, female investors are associated with firms that are on average older and offer 0.02% more equity.Practical implicationsThese findings have implications for crowdfunding platforms managers when selecting their target companies and policymakers when defining political actions to promote greater use of equity crowdfunding among female entrepreneurs and decrease barriers hindering women’s access to investment.Originality/valueUnique in its proposition and data usage, this study sheds light on the relationship between investors and entrepreneurs in the Latin American equity crowdfunding market.
Indirect customer-to-customer interactions and experiential value: examining solo and social diners
Authors: Han Wenjia , Jiang Wen , Tang Jason , Raab Carola , Krishen Anjala 
Published: January 2022

Purpose
This study aims to examine whether indirect customer-to-customer interactions (CCI) affect consumers’ behavioral intentions and how that effect is generated. It also explores the effect of dining experience on customer behavioral intentions and how that effect varies by party type.

Design/methodology/approach
The research consists of an experimental survey-based study of n = 491 real-world consumers from a marketing research panel. Structural equation models are analyzed to examine hypothesized relationships.

Findings
Indirect CCIs significantly affect all five dimensions of experiential value. Food and beverage (F&B) excellence, aesthetics and service excellence positively affect customer revisit intentions and word-of-mouth intentions via restaurant image. Furthermore, party type moderates the effect of aesthetics on behavioral intentions so that the effect is significant for the social diner group only. Customer return on investment and playfulness show non-significant impacts on behavioral intentions.

Practical implications
Managers should be aware that indirect CCIs influence all aspects of the restaurant experience. Since F&B excellence, aesthetics and service excellence affect restaurant image and behavioral intentions, management can operationalize these elements of service. The impact of aesthetics differs by consumers’ party type, enabling management to create unique servicescapes based on their target customer segment.

Originality/value
The study pioneers an investigation of how indirect CCI is associated with behavioral intentions through the mediating effects of experiential value and restaurant image. It contributes to the literature by examining how the impact of diners’ experiences differs by party type.
“Should we get support or just guidelines?” (self) assessment on mentoring of early childhood education students
Authors: Visnjic Jevtic Adrijana , Rogulj Edita 
Published: January 2022

PurposeThe aim of this research was to find out students' and mentors' attitudes toward the quality of mentoring support during teaching practicums. The research sought to determine whether there is any difference in (self) assessment between teacher mentors and early childhood education students.Design/methodology/approachThrough the quantitative research methodology, the Crisp (2009) College Student Mentoring Scale (CSMS) instrument was used to assess the quality of mentoring support during teaching practicums. Assessments were made in relation to the following variables: support in the areas of psychological and emotional needs, support in professional development and the development of professional competencies and the role of mentors as models. Early childhood education students (n1 = 105) and mentors (n2 = 54) of teaching practicums at the Faculty of Teacher Education, University of Zagreb, participated in the research.FindingsThe results of the research show that there is a statistically significant difference between student assessments and mentor self-assessment with regard to all researched areas of support. Mentors rated their mentoring skills higher than students did.Originality/valueAn approach in which mentoring is assessed in the context of support to students in different areas (e.g. psychological, emotional, professional) is rarely used in early childhood teacher education. Results indicate the need for a systematic evaluation of mentoring and the design of programs to strengthen mentoring competences.
Evaluation of birth companions perinatal and peer support provision in two prison settings in England: a mixed-methods study
Authors: Thomson Gill , Mortimer Rose , Baybutt Michelle , Whittaker Karen 
Published: January 2022

Purpose
This paper reports on insights from an evaluation of Birth Companions (BC) (a UK-based charity) perinatal support in two prison settings in England. The initiative involved the provision of group and/or one-to-one perinatal support and training women prisoners as peer supporters.

Design/methodology/approach
A mixed-methods study was undertaken that involved observations of support groups and peer support supervision sessions (n = 9); audio recorded interviews (n = 33) with prison and health-care staff, women in prison, peer supporters and BC staff; analysis of existing routinely collected data by BC and notes undertaken during regular meetings (n = 10) with the BC Project Manager. Thematic analysis was undertaken supported by MAXQDA qualitative data analysis software.

Findings
BC provided instrumental/practical support, emotional support, information support, signposting to services and advocating for women to the prison concerning their perinatal needs and rights. Key themes revealed that support had an impact on the lives of perinatal women by creating a safe place characterised by meaningful interactions and women-centred approaches that facilitated access to wider care and support. The service made a difference by empowering women and providing added value for peer supporters, prison, health-care and BC staff. Key enablers and strategies for the care of perinatal women and the delivery of perinatal support are also detailed.

Originality/value
Through longitudinal data and the involvement of a range of stakeholders, this study evidences the subtleties of support provided by BC and the potential it has to make a difference to perinatal women in prison and those volunteering or working within the prison system.
Board diversity and working capital management strategies: evidence from energy sector of Pakistan
Authors: Khan Ammar Nawaz , Yahya Farzan , Waqas Muhammad 
Published: January 2022

Purpose This study investigates the mediating role of working capital management (WCM) efficiency between board diversity (based on gender and financial knowledge) and firm performance. The study further examines which WCM approach (conservative, moderate, and aggressive) they employ to increase (decrease) firm performance.Design/methodology/approach The study employs listed energy firms of Pakistan over the period 2010 to 2019. The system generalized method of moments estimator and logit model are utilized to estimate the underlying relationships.Findings The results show that WCM efficiency partially mediates the relationship between board financial expertise (BFE) and firm performance. Nonetheless, the presence of female directors is merely symbolic until they reach a certain level as only the quadratic term of board gender diversity (BGD) has a significant effect on firm performance. Female directors do not influence WCM efficiency. The results also demonstrate that BGD encourages a conservative WCM approach, while BFE encourages a moderate WCM approach. Furthermore, both conservative and moderate WCM approaches are significantly associated with firm performance.Practical implications The findings hold implications for increasing the representation of women and financial experts on board to improve the capital structure decisions of the energy firms in Pakistan.Originality/value This study is the first attempt to explore the mediating role of WCM efficiency between board diversity and firm performance. To the best of the authors' knowledge, no previous study has investigated the effect of BGD and BFE on different WCM approaches distinctly.
What motivates retail investors to invest in government-issued digital sukuk during COVID-19?
Authors: Bin-Nashwan Saeed Awadh , Muneeza Aishath , Kunhibava Sherin 
Published: January 2022

Purpose
To analyse Sukuk Prihatin (SP), the first-ever retail digital sukuk issued by the Government of Malaysia in the midst of the COVID-19 pandemic, as part of the national economic recovery plan. The issuance of SP was oversubscribed, even upsized, resulting in the government announcing its intention to issue similar types of sukuk in the future. In light of this, the purpose of this study is to understand the motivation for retail investors to invest in SP.

Design/methodology/approach
The purposive sampling method was applied via a self-administered survey, while the cross-sectional data were empirically tested using the SmartPLS 3.2.9 structural equation modelling. An integrated model of the theory of planned behaviour and social cognitive theories was used in determining investors’ intention to invest in SP.

Findings
The findings of this research revealed that attitude (ATT) towards SP investment (SPI), social norms (SN), perceived control (PBC) regarding SPI, sukuk features (SF), tax incentives (TI) and the spirit of unity and brotherhood (SUB) were significant determinants of investors’ willingness to invest in SP. This research also provided evidence for significant national pride-moderated interactions of ATT, SN, PBC, SF, TI and digitisation on investment intention.

Practical implications
The outcome of this study could assist governments and policymakers to structure sukuk and other debt-based capital market products to attract retail investors who would be willing to invest in the development of the nation in the midst of a crisis.

Originality/value
This study is the first of its kind to investigate various relevant predictors, which have been derived from behavioural, contextual and motivational perspectives. These predictors could influence investors’ perceptions of an innovative sukuk like SP, which was issued in the midst of a pandemic. The value of this study is its possible use by governments and policymakers to further develop debt-based capital market products that have the dual function of an investment vehicle and a source of funds for the economic recovery of a nation.
SafeCX: a framework for safe customer experience in omnichannel retailing
Authors: Rahman Syed Mahmudur , Carlson Jamie , Chowdhury Noman H. 
Published: January 2022

Purpose
The experience of safety as perceived by customers is a central issue in retailing, and its importance has increased because of the pandemic. Substantial literature exists addressing different factors related to safety/security experience in different types of retail channels. However, what is missing is a unified framework to guide safe customer experience initiatives across all channels. Therefore, this study aims to investigate the safety elements in omnichannel retailing as perceived by customers and how these safety elements affect customer experience (CX) judgments and consumer behavior in a post-pandemic context.

Design/methodology/approach
A systematic literature review on safety/security studies in a retail context is conducted, followed by a qualitative study driven by a means-end-chain laddering technique collecting data from 62 retail customers in Australia, the USA and UK.

Findings
Fourteen distinct safety elements in omnichannel retailing are identified. Four elements are relevant to the CX at the pre-purchase stage of the customer journey: social inclusiveness, role readiness, employment policy and safety policy enforcement. Six elements are relevant to the during-purchase stage: physical safety, personal hygiene, spatial distancing, fraud prevention, security surveillance and safety signal. The remaining four elements are relevant to the post-purchase stage: delivery safety, safety recall, mental health and data usage.

Originality/value
This study presents a new unified framework addressing safety and security in post-pandemic retail service settings. The SafeCX framework offers researchers and managers a holistic understanding of the distinct safety elements that shape customers’ perceptions across each customer journey stage of the retail CX.
Wholesale-price vs cost-sharing contracts in a green supply chain with reference price effect under different power structures
Authors: Zhang Ranran , Liu Jinjin , Qian Yu 
Published: January 2022

PurposeThis research aims to examine which cooperative contract (wholesale-price contract or cost-sharing contract) can more effectively upgrade the green degree of product and promote demand when considering consumer reference price effect under different power structures.Design/methodology/approachThis research investigates a dyadic green supply chain composed of one manufacturer and one retailer. Four Stackelberg game models with a cost-sharing contract or a wholesale-price contract are built in retailer-led and manufacturer-led scenarios, respectively. Using backward induction, the optimal green decision under each model is obtained. In addition, the optimal cooperative contract is proposed by comparing these four models.FindingsIt is found that under consumer reference price effect, a cost-sharing contract outperforms a wholesale-price contract in upgrading product greenness and promoting demand. Under any single contract, the retailer-led situation is more conducive to improving product greenness than the manufacturer-led situation. Moreover, consumer reference price effect would reduce the sharing ratio of a cost-sharing contract when the manufacturer dominates, but it could mitigate the problem of double marginalization by reducing wholesale and retail prices under both types of contracts, which would enhance consumer surplus.Originality/valueIt is a new attempt to incorporate consumer reference price effect and power structure into a green supply chain framework and proposes a novel demand function that simultaneously emphasizes consumer reference price effect, consumer environmental awareness and product green attribute. In addition, it provides managerial insights for business managers to choose green cooperative contracts with consumer reference price effect under different power structures.
