Published: April 2023

PurposeThe proliferation of ride-hailing businesses brings significant considerations for improving the driver's operational performance. Informed by the literature on sharing economy, general deterrence theory and protection motivation theory this research investigates the behavioral factors impacting ride-hailing drivers' operational performance.Design/methodology/approachThe authors empirically test the antecedents impacting a ride-hailing driver's operational performance using an online survey dataset comprising 513 ride-hailing drivers working for Uber and Lyft in the United States.FindingsRide-hailing drivers' intention to comply with the ride-hailing company guidelines results in better operational performance for the driver. Moreover, drivers believe that ride-hailing companies have effective penalties to deter drivers from violating company guidelines. However, drivers also believe that the chances of being caught while ignoring the company guidelines are low.Practical implicationsThe results of this research support the decision-making processes of ride-hailing company managers and offer insights on how managers can enhance the operational performance of their drivers.Originality/valueThis study provides unique contributions to emerging research at the intersection of peer-to-peer asset sharing, behavioral studies and technology management. This research is one of the first to explore the role of behavioral factors such as coping mechanisms on the operational performance of sharing economy workers.

Authors: Pizzichini Lucia , Temperini Valerio , Caboni Federica , Papa Armando 
Published: April 2023

PurposeThis paper aims to contribute to overcoming the gap existing in the supply chain literature related to digital servitization by bridging digital servitization with knowledge management and identifying the rise of digital knowledge servitization as a driver for changes in the supply chain business model towards open innovation.Design/methodology/approachThe study follows an inductive grounded theory approach for theory building. To analyse the impact of digital knowledge servitization, in-depth interviews of managers in the main business units of the Volvo Group supply chain ecosystem were carried out.FindingsThe results show how the digital servitization process affects the supply chain business model, highlighting the central role of knowledge in the service ecosystem and the rise of the theoretical concept of digital knowledge servitization. In particular, through the Innovation Lab (Volvo Group) study, the paper contributes to bringing together the theoretical knowledge-based view of servitization with the digital servitization concept, which demonstrates the role of this combined perspective in the transformation of the supply chain; this is carried out by introducing a new business model based on open innovation in inbound and outbound processes.Practical implicationsThe research offers interesting insights from a managerial perspective, as increasingly advanced and complex digital solutions require shorter times in supply chain management (SCM). Companies need to be able to quickly manage information and knowledge flows deriving from internal and external interactions and involvement with external actors upstream and downstream of the supply chain ecosystem. Therefore, the digital knowledge servitization of the supply chain also highlights implications for managers in terms of human resources management.Originality/valueThe novel research goal is to contribute to the supply chain literature by integrating the digital servitization with the knowledge view and analysing the impact on the inbound and outbound supply chain through the introduction of an open innovation business model.

Published: April 2023

PurposeThis study aims to identify the significant factors of the multi-dimpling process, determine the most influential parameters of multi-dimpling to increase the dimple sheet strength and make a low-cost model of the multi-dimpling for sheet metal industries. To create an empirical expression linking process performance to different input factors, the percentage contribution of these elements is also calculated.Design/methodology/approachTaguchi grey relational analysis is used to apply a new effective strategy to experimental data in order to optimize the dimpling process parameters while taking into account several performance factors and low-cost model. In addition, a statistical method called ANOVA is used to ensure that the results are adequate. The optimal process parameters that generate improved mechanical properties are determined via grey relational analysis (GRA). Every level of the process variables, a response table and a grey relational grade (GRG) has been established.FindingsThe factors created for experiment number 2 with 0.5 mm as the sheet thickness, 2 mm dimple diameter, 0.5 mm dimple depth, 8 mm dimples spacing and the material of SS 304 were allotted rank one, which belonged to the optimal parameter values giving the greatest value of GRG.Practical implicationsThe study demonstrates that the process parameters of any dimple sheet manufacturing industry can be optimized, and the effect of process parameters can be identified.Originality/valueThe proposed low-cost model is relatively economical and readily implementable to small- and large-scale industries using newly developed multi-dimpling multi-punch and die.
Carbon allowance approach for capital-constrained supply chain under carbon emission allowance repurchase strategy
Authors: Wang Yuyan , Lin Fei , Cheng T.C.E. , Jia Fu , Sun Yulin 
Published: April 2023

PurposeThe purpose of this study is to investigate which of the two carbon allowance allocation methods (CAAMs), i.e. grandfathered system carbon allowance allocation (GCAA) and baseline system carbon allowance allocation (BCAA), is more beneficial to capital-constrained supply chains under the carbon emission allowance repurchase strategy (CEARS).Design/methodology/approachAdopting CEARS to ease the capital-constrained supply chains, this study develops two-period game models with manufacturers as leaders and retailers as followers from the perspective of profit and social welfare maximization under two CAAMs (GCAA and BCAA), where the first period produces normal products, and the second period produces low-carbon products.FindingsFirst, higher carbon-saving can better use CEARS and achieve a higher supply chain profit under the two CAAMs. However, the higher the end-of-period carbon price is, the lower the social welfare is. Second, when carbon-saving is small, GCAA achieves both economic and environmental benefits; BCAA reduces carbon emissions at the expense of economic benefit. Third, the supply chain members gain higher profits and social welfare under GCAA, so the government and supply chain members are more inclined to choose GCAA.Originality/valueBy analyzing the profits and total carbon emissions of capital-constrained supply chains under GCAA and BCAA, this study provides theoretical references for retailers and capital-constrained manufacturers. In addition, by comparing the difference in social welfare under GCAA and BCAA, it provides a basis for the government to choose a reasonable CAAM.
Health-care providers' experiences during the COVID-19 pandemic: lessons for leaders
Authors: Corcoran Lynn , Perry Beth , Jay Melissa , Edwards Margaret , Jerry Paul 
Published: April 2023

Purpose
The purpose of this qualitative research study is to explore health-care providers’ perspectives and experiences with a specific focus on supports reported to be effective during the COVID-19 pandemic. The overarching goal of this study is to inform leaders and leadership regarding provision of supports that could be implemented during times of crisis and in the future beyond the pandemic.

Design/methodology/approach
Data were collected by semi-structured, conversational interviews with a sample of 33 health-care professionals, including Registered Nurses, Nurse Practitioners, Registered Psychologists, Registered Dieticians and an Occupational Therapist.

Findings
Three major themes emerged from the interview data: (1) professional and personal challenges for health-care providers, (2) physical and mental health impacts on health-care providers and (3) providing supports for health-care providers. The third theme was further delineated into three sub-theses: formal resources and supports, informal resources and supports and leadership strategies.

Originality/value
Health-care leaders are advised to pay attention to the voices of the people they are leading. It is important to know what supports health-care providers need in times of crisis. Situating the needs of health-care providers in the Carter and Bogue Model of Leadership Influence for Health Professional Wellbeing (2022) can assist leaders to deliberately focus on aspects of providers’ wellbeing and remain cognizant of the supports needed both during a crisis and when circumstances are unremarkable.
Punitive switching costs and behavioral responses in the context of contractual services
Authors: Chuang Yi-Fei , Dinh Cong-Minh , Lu Wei-Min 
Published: April 2023

Purpose
Contractual services are characterized by features such as termination fees, long-term commitment, and complex terms. When customers find better deals from other providers, they may want to switch, but contractual obligations prevent them from doing so. Thus, this study aims to draw upon the stimulus-organism-response paradigm and theories of emotion regulation to examine how punitive switching costs (PSCs) can evoke negative emotions (NEs) from customers and, consequently, lead to negative behavioral responses in contractual service settings.

Design/methodology/approach
This study collected data from 395 customers of telecommunications companies, fitness centers, tutoring firms/centers, and house leasing companies in Taiwan. We tested the hypotheses using partial least squares structural equation modeling via SmartPLS 3.0.

Findings
The results show that NEs partially mediate the relationship between PSC and customers’ switching intention and negative word-of-mouth. This study also finds alternative attractiveness (AA) and service recovery (SR) do not moderate the PSCs–NEs relationship, but AA does directly influence NEs.

Originality/value
First, this study contributes to the literature on switching costs by exploring how PSC exerts a detrimental impact on behavioral responses. Second, this study adds to the literature on service failures by identifying the mediating role of NEs in such a relationship.

PurposeThis article shares how providing teacher candidates with experiences in a predominantly black elementary school for their clinical experiences highlighted a need to recognize, acknowledge and address anti-blackness in teacher candidates’ clinical courses. As well as, a need to emphasize the brilliance and assets of black students. Additionally, this article shares ways in which those involved in the work of school-university or professional development school (PDS) partnerships can incorporate practices that address anti-blackness in clinical practice.Design/methodology/approachConceptual paper sharing experiences addressing anti-blackness in school-university partnerships.FindingsNational Association of Professional Development Schools (NAPDS) recently revised their Nine Essentials to include this revised version of Essential 1: A comprehensive mission which calls for the advancement of equity, antiracism and social justice within and among schools, colleges/universities and their respective community and professional partners. The work that the author presents in this article around preparing teacher candidates to address anti-blackness fits into the call of Essential 1 because when anti-blackness is addressed equity, antiracism and social justice can be part of the educational experiences of black children. This article shares how providing teacher candidates experiences in a predominantly black elementary school for their clinical experiences highlighted a need to recognize, acknowledge and address anti-blackness in teacher candidates’ clinical practice. As well as, a need to emphasize the brilliance and assets of black students. Additionally, this article shares ways in which those involved in the work of school-university or PDS partnerships can incorporate practices that address anti-blackness in clinical courses.Originality/valueThe author believes that this manuscript is appropriate for publication because it addresses a necessary shift that must happen in clinical practice by recognizing, acknowledging and addressing anti-blackness, as well as making sure teacher candidates are prepared to teach black students. This manuscript has not been published and is not under consideration for publication elsewhere. The author has no conflicts of interest to disclose.
Stiffness optimization based on muscle fatigue and muscle synergy for passive waist assistive exoskeleton
Authors: Pang Muye , Li Ruiqing , Ding Ying , Tang Biwei , Luo Jing , Xiang Kui 
Published: April 2023

Purpose
This paper aims to optimize the stiffness coefficient of the elastic element for a passive waist assistive exoskeleton (WAE). There is a tradeoff between stiffness coefficient of elastic element of the exoskeleton and work efficiency of the wearer, because elastic element affects original bending motion of the wearer and the force requirement of erector spinae is compensated by the other muscles. However, there is no accepted conclusion on how to determine the proper stiffness coefficient, especially with respected to the effort of groups of muscles, not only erector spinae.

Design/methodology/approach
In this study, a consumption indicator based on muscle fatigue of seven muscles is proposed and a Bayesian-based human-in-the-loop optimization approach is adopted to optimize the stiffness coefficient. Pneumatic artificial muscles are used to replace the mechanical elastic part to adjust the assistive force automatically. The proposed optimization method is verified by the way of load-lifting experiments with three different conditions: without exoskeleton, with fixed air pressure and with optimized air pressure. Six subjects participated in the experiment and each experiment is performed in different day.

Findings
Compared with No-Exo condition and static assistance condition, the parameter-optimized waist exoskeleton averagely reduces muscle fatigue of the six subjects by 45.30 ± 29.14% and 30.94 ± 30.29%, respectively. The experimental results indicate that the proposed method is effective to reduce muscle fatigue during stoop lifting task.

Originality/value
This paper provides a novel cost function construction method based on muscle fatigue and muscle synergy for passive WAE stiffness optimization.
Heterogeneous effects of urbanization and environment Kuznets curve hypothesis in Africa
Authors: Hussain Muhammad Noshab , Li Zaiyang , Yang Shaohua 
Published: April 2023

AbstractThis work explores the heterogeneous effect of urbanization and nonrenewable energy consumption on the environment in 54 African nations. Panel data were used from 1996 to 2019. For estimation, panel quantile regression analysis, augmented mean group, panel threshold regression, and the environment Kuznets curve hypothesis were applied to check the relationship between income and carbon emissions. The study's outcome demonstrates that urbanization and nonrenewable energy consumption degrade the environment in Africa. Furthermore, an inverted U‐shape relationship exists between economic growth and CO2 emissions, confirming the environmental Kuznets curve hypothesis. The findings indicate that urbanization should be planned; otherwise, urbanization can cause environmental degradation. African countries must adopt green urbanization and use renewable energy and clean manufacturing technologies. The institutions are encouraged to execute the standard, regulatory environment, and policies to reduce carbon emissions. Countries throughout the African continent should actively respond to the issues by charting a separate and diverse route for urban development.

Published: April 2023

AbstractForensically relevant single nucleotide polymorphisms (SNPs) can provide valuable supplemental information to short tandem repeats (STRs) for investigative leads, and genotyping can now be streamlined using massively parallel sequencing (MPS). Dust is an attractive evidence source, as it accumulates on undisturbed surfaces, often is overlooked by perpetrators, and contains sufficient human DNA for analysis. To assess whether SNPs genotyped from indoor dust using MPS could be used to detect known household occupants, 13 households were recruited and provided buccal samples from each occupant and dust from five predefined indoor locations. Thermo Fisher Scientific Precision ID Identity and Ancestry Panels were utilized for SNP genotyping, and sequencing was completed using Illumina® chemistry. FastID, a software developed to permit mixture analysis and identity searching, was used to assess whether known occupants could be detected from associated household dust samples. A modified “subtraction” method was also used in FastID to estimate the percentage of alleles in each dust sample contributed by known and unknown occupants. On average, 72% of autosomal SNPs were recovered from dust samples. When using FastID, (a) 93% of known occupants were detected in at least one indoor dust sample and could not be excluded as contributors to the mixture, and (b) non‐contributor alleles were detected in 54% of dust samples (29 ± 11 alleles per dust sample). Overall, this study highlights the potential of analyzing human DNA present in indoor dust to detect known household occupants, which could be valuable for investigative leads.
Evaluation of bioactive low‐density polyethylene (LDPE) nanocomposite films in combined treatment with irradiation on strawberry shelf‐life extension
Authors: Begum Tofa , Follett Peter A. , Shankar Shiv , Moskovchenko Lana , Salmieri Stephane , Lacroix Monique 
Published: April 2023

AbstractA low‐density polyethylene (LDPE) film reinforced with cellulose nanocrystals (CNCs) with an encapsulated bioactive formulation (cinnamon essential oil + silver nanoparticles) was developed for preservation of fresh strawberries. Antimicrobial activity of the active LDPE films was tested against Escherichia coli O157:H7, Salmonella typhimurium, Aspergillus niger, and Penicillium chrysogenum by agar volatilization assay. The optimal condition of the films showed ≥75% inhibitory capacity against the tested microbes. Strawberries were stored with different types of films: Group 1 (control): (LDPE + CNCs + Glycerol), Group 2: (LDPE + CNCs + Glycerol + AGPPH silver nanoparticles), Group 3: (LDPE + CNCs + Glycerol + cinnamon), Group 4: (LDPE + CNCs + Glycerol + active formulation), and Group 5: (LDPE + CNCs + Glycerol + active formulation + 0.5 kGy γ‐radiation) at 4°C for 12 days. Weight loss (WL) (%), decay (%), firmness (N), color, and total phenolics and anthocyanin content of the strawberries were measured. Results showed that the most effective LDPE‐nanocomposite film for reducing the microbial growth was LDPE + CNCs + Glycerol + active formulation film (Group 4). When combined with γ‐irradiation (0.5 kGy), the LDPE + CNCs + Glycerol + active formulation (Group 5) significantly reduced both decay and WL by 94%, as compared to the control samples after 12 days of storage. Total phenols (from 952 to 1711 mg/kg) and anthocyanin content (from 185 to 287 mg/kg) increased with storage time under the different treatments. The mechanical properties, water vapor permeability (WVP), and surface color of the films were also tested. Though the WVP of the films were not influenced by the types of antimicrobial agents, they did significantly (p ≤ 0.05) change color and mechanical properties of the films. Therefore, combined treatment of active film and γ‐irradiation has potential as an alternative method for extending the shelf‐life of storage strawberries while maintaining fruit quality.Practical ApplicationBioactive Low‐density polyethylene (LDPE) nanocomposite film was developed in the study by incorporating active formulation (essential oil and silver nanoparticle) to extend the shelf life of stored strawberries. The bioactive LDPE‐based nanocomposite film along with γ‐irradiation could be used to preserve fruits for long‐term storage by controlling the growth of foodborne pathogenic bacteria and spoilage fungi.

Published: April 2023

AbstractThis study investigates the fabrication of films based on a polymer containing nanoclay, sodium diacetate (SDA), and tert‐butyl hydroquinone (TBHQ) for packaging rainbow trout fillets. The films were prepared by the addition of 2% SDA (SDA film), 2% TBHQ (TBHQ film), and a combination of both (1% SDA + 1% TBHQ) into polyethylene polymer (93.00%) and montmorillonite nanoclay (5.00%). A film lack of nanoclay, SDA, and TBHQ was prepared and considered a control film. A film was also prepared by the addition of 95 g polyethylene + 5 g nanoclay (Nanoclay). Morphological properties of the films were investigated by a scanning electron microscope (SEM). In vitro antioxidant properties and antibacterial activities of the films and their effects as the coating on fish samples were evaluated against Listeria monocytogenes, Salmonella typhimurium, and Escherichia coli. The effects of films on oxidative stability, antibacterial activity, pH, total volatile basic nitrogen (TVBN), and total viable count (TVC) of fish samples were assessed. The SEM results showed the homogenous dispersion of SDA and TBHQ into films. The SDA, TBHQ, and ST films showed antibacterial activity against L. monocytogenes, S. typhimurium, and E. coli compared with the control film as the coating and under in vitro conditions (p < 0.05). The TBHQ and ST films exhibited higher antioxidant activity and prevented the oxidation as the coating. The films prepared from the SDA, TBHQ, and ST prevented an increase in TVC and TVBN (p < 0.05). The ST films can prevent spoilage in fish samples and can be utilized in the food industry.Practical ApplicationWe successfully prepared films with the help of nanoclay, sodium diacetate (SDA), and tert‐butyl hydroquinone (TBHQ) on polyethylene for packaging fish fillets. Films containing SDA, TBHQ, and nanoclay showed antibacterial activity and prevented spoilage. The films can be used for packaging fish fillets.
