An exploration of the applicability of Lean Startup in small non-digital firms: an effectuation perspective
Authors: Solaimani Sam , van Eck Tijl , Kievit Henk , Koelemeijer Kitty 
Published: July 2022

PurposeLean Startup (LS) has gained considerable traction in the startup scene, especially within digital firms where the concept finds the concept's genesis. However, there are more and more calls in the entrepreneurship literature to study LS's application beyond the digital context. The purpose of this study is to explore the applicability of LS within the largely under-researched context of non-digital entrepreneurs. To structure the authors' understanding of the participating entrepreneurs' cognitive and behavioural logic, effectuation theory is applied.Design/methodology/approachTo explore how LS is applied in non-digital settings, this study analyses the LS approach of 15 Dutch brick-and-mortar and click-and-mortar Small to Medium-sized Enterprises (SMEs) and startups.FindingsThis study provides empirical evidence that non-digital entrepreneurs pursue an effectual logic in their LS approach. However, the entrepreneurs' LS approach appeared to be contextualised to the non-digital contexts' inherent constraints and trade-offs. Such contextualisation calls for a particular set of skills and competencies, including applying mixed-methods cross-validation, affinity and passion for craftsmanship and aesthetics, inferring from limited, qualitative, and often skewed data, establishing an empathetic collaborative relationship with customers and suppliers, and leveraging prior market knowledge and experience.Originality/valueThis study advances the current understanding of the LS applicability and gives a more nuanced account of how LS is practised in the context of non-digital firms, the challenges entrepreneurs involved in non-digital firms need to overcome, and the skills and competencies they need to possess. In practical terms, the findings help non-digital entrepreneurs and coaches to be more heedful of the contextual peculiarities when employing LS.

Published: July 2022

PurposeThe objectives of this paper are two-fold: first, to empirically compare and contrast the salient features of three financial instruments (FIs), namely sustainable and responsible investment (SRI) ṣukūk, social impact bonds (SIBs) and conventional bonds (CBs) and second, to examine the differences between the perceptions of the investors and the developers on the features of the three FIs.Design/methodology/approachUsing a questionnaire survey, 251 completed and useable responses were received, representing a 42.54% response rate. In examining the differences and similarities in the characteristics of the three FIs, the inferential statistical of frequency and percentage were used. Wilcoxon and Mann–Whitney tests were conducted to investigate the differences in the salient features of the three FIs and the differences between the investors and developers' perceptions on the salient features of SRI ṣukūk, SIBs and CBs, respectively.FindingsThe results reveal that stakeholders view SRI ṣukūk, SIBs and CBs to be statistically significantly different from each other. This shows that stakeholders do not view SRI ṣukūk as “old wine in a new Sharīʿah-compliant bottle” but instead considered different from SIBs and CBs. Furthermore, stakeholders also differentiate between SIBs and CBs.Originality/valueThe paper provides empirical evidence that Islamic finance (IF) instrument, represented by SRI ṣukūk, is viewed as different instruments to conventional tools, represented by SIBs and CBs. First, it debunks the notion that IF is viewed as similar to its conventional counterpart. Second, SIBs are seen as different from CBs, illustrating the distinct categorisation of impact investing instruments. As such, third, the development of SRI ṣukūk and SIBs can provide diversification to portfolios as it is a unique instrument in the social finance and financial market.
Paradoxical tensions impacting small-series production implementation in high-cost contexts: insights from the EU apparel industry
Authors: Harper Sara 
Published: July 2022

PurposeWhile localized small-series production is a significant opportunity, various tensions challenge implementation in high-cost contexts. This paper explores how managers view and respond to different tensions in small-series production implementation by adopting a paradox-based perspective.Design/methodology/approachThe paper presents a multiple case study addressing small-series production within EU's apparel industry, as key context to address managerial awareness, and responses to tensions regarding location and supply network configuration decisions. Seven cases were selected for variation in customization and implementation (early/established), ownership, location and company size, to identity commonalities.FindingsThe study highlights performing tensions related to sustainability, and risk, in addition to confirming traditional goal-related tensions predominantly impacting small volume production. With on-demand/custom production, tensions include costs in conflict with process scale, and several process-related tensions (flexibility, expansion/development, risk management). Identified multidimensional responses do not include location or structural decisions, instead focusing on synthesis, through product-operations efficiency, knowledge development and process innovation and supply chain collaboration. Temporal separation is found with customization, including reducing product/process complexity short-term with enhancing process development, which suggests latent learning tensions and limited awareness.Research limitations/implicationsFuture research should address the extent to which tensions can be resolved or remain paradoxical, as well as dynamic decision-making and latent tensions.Originality/valueThe paper shows how paradox theory facilitates a deeper understanding of complex network configuration decisions, including reshoring/localization. The findings identify organizing tensions/elements and elaborate upon performing/performing-organizing tensions suggested with small-series production, location decisions and supply chain management.
Application selection of dry film lubricant on carbon steel surface and antifriction mechanism
Authors: Fanjing Meng , Pang Minghua , Ma Lijie 
Published: July 2022

Purpose
Carbon steel has a high application rate in modern industry, but this type of steel has the defect of high wear. This study aims to improve the surface friction and wear performance of carbon steel under such working conditions.

Design/methodology/approach
In this study, a dry film lubricant based on graphite powder was prepared by the ultrasonic dispersion method, and deposited on the surface of carbon steel specimens by the simple pressure spraying technology. At the same time, molybdenum disulfide and polytetrafluoroethylene dry film lubricants were developed by the same method, and the comparative experimental study on friction and wear was carried out in the end-face friction tester.

Findings
The results show that the deposition effect of graphite and molybdenum disulfide dry film lubricants on the surface of carbon steel is obviously better than that of polytetrafluoroethylene dry film lubricant. Compared with molybdenum disulfide and polytetrafluoroethylene dry film lubricant, graphite dry film lubricant has the best friction and wear performance on the surface of carbon steel. The working life of carbon steel specimens sprayed with graphite dry film lubricant decreases with the increase of pressure load and rotation speed. The combination of load and sliding speed will accelerate the transition of the coating to a stable direction. In addition, the micro lubricant particles formed in the wear process will form particle flow lubrication, and the appropriate addition of particle powder of the same material will also prolong the normal antifriction time of the lubricant.

Originality/value
These findings developed a dry film lubricant that can effectively improve the friction and wear properties of carbon steel surface.
Gear and bearing power losses: from dip to minimum quantity lubrication
Authors: Yilmaz Mustafa , Önüt Ali , Lohner Thomas , Stahl Karsten 
Published: July 2022

Purpose
This paper aims to address the influence of lubrication methods on operational characteristics, power losses and temperature behavior of gears and bearings. It contributes to the improvement of resource and energy efficiency of geared transmissions.

Design/methodology/approach
Experimental investigations were performed at a gear and bearing power loss test rig. Thereby, dip lubrication, injection lubrication with injection volumes from 0.05 to 2.00 l/min and minimum quantity (MQ) lubrication with an injection volume as little as 28 ml/h were considered. Measurements were evaluated in terms of no-load and load-dependent power loss, bulk temperatures and mean gear coefficients of friction.

Findings
Results show strongly reduced no-load gear and bearing losses for lubrication methods with low lubricant quantities. Load-dependent losses are similar to conventional lubrication methods and tend to be lower at high speed. This is related to higher bulk temperatures, as the heat dissipation of lubrication methods with low oil quantities is limited. Limited thermal load limits were shown to be extended by LowLoss gears.

Originality/value
Systematic investigations were conducted to evaluate the influence of dip, injection and MQ lubrication on power loss and temperature behavior of gears and bearings. The results of this study support further research on needs-based lubrication methods for gearboxes.
National culture and audit report lag: cross-country investigation
Authors: Toumi Fadoua , Khlif Hichem , Khelil Imen 
Published: July 2022

PurposeThis study aims to investigate the effect of national culture (power distance, individualism, masculinity, uncertainty avoidance and long-term orientation) on audit report lag.Design/methodology/approachThe authors use two econometric approaches (ordinary least squares (OLS) and quantile regression) using STATA software for a sample of 1,208 firm-year observations over the period of 2017–2018.FindingsUsing Hofstede’s (2001) cultural dimensions (power distance, individualism, masculinity, uncertainty avoidance and long-term orientation), the authors find that masculinity and long-term orientation are positively associated with audit report lag, while uncertainty avoidance is negatively associated with the same variable. Quantile regressions suggest that the adverse effect of masculinity on audit report lag is more prevailing for companies communicating companies' annual reports in a timely manner. Furthermore, the positive association between power distance and audit report lag exists only under tardy disclosure regime. Quantile regressions also confirm that the negative (positive) effect of uncertainty avoidance (long-term orientation) on audit report lag is maintained under different timely disclosure regime. Additional analysis conducted with respect to legal system shows that individualism becomes a significant predictor of audit delays with a significant negative effect for common law countries, while uncertainty avoidance has a positive effect on the same variable in civil law countries characterized by high level of discretion and secrecy.Practical implicationsThe results of this study suggest that national culture as an informal institution may complement formal institutions (e.g. financial markets) in promoting timely disclosure. For instance, foreign investors may view high uncertainty avoidance scores, in common law emerging economies, as an indicator of transparency and timely disclosure.Originality/valueThis study adds to the extant literature a further understanding of the impact of cultural dimensions on timely disclosure, as proxied by, audit report lag. The use of quantile regression approach shows how different timely disclosure regime may affect the association between masculinity, power distance and audit report lag.
Jurisdictional arbitrage: combatting an inevitable by-product of cryptoasset regulation
Authors: Draganidis Sideris 
Published: July 2022

Purpose
This paper aims to provide an overview of different issues related to jurisdictional arbitrage found in general regulatory arbitrage literature and their projection to the specific area of cryptoasset regulation.

Design/methodology/approach
By distinguishing any parallel, analogous and neighbouring concepts, this paper attempts to clarify the notion of jurisdictional arbitrage. By discussing certain aspects and effects of three regulatory regimes, BitLicense, 5th Anti-Money Laundering Directive (AMLD5) and the European Commission’s Proposal for a Regulation on Markets in Crypto-assets (MiCa), it makes clear that national/State/regional policymakers have already failed to create arbitrage-proof regulatory frameworks by acting exclusively within their jurisdictional limits. Against this background, this paper discusses briefly regulatory competition and international harmonisation as alternative solutions to inappropriate and ineffective national/regional legislative approaches.

Findings
Based on a structured theoretical analysis, this paper reaches three important findings. First, academics, international bodies and other commentators use inaccurately the general concept of “regulatory arbitrage” to refer to the specific problem of jurisdictional arbitrage creating in this way an interpretative confusion; second, commentators confuse jurisdictional conflicts with jurisdictional arbitrage; third, the solutions to this regulatory problem can actually be found in its underlying causes.

Originality/value
To the best of the author’s knowledge, this is the first specific-issue paper on jurisdictional arbitrage in the context of cryptoasset regulation and aims to trigger further academic discussion on this evolving phenomenon and inform the development of future cryptoasset regulation combatting this problem.
Spatio-temporal heuristic method: a trajectory planning for automatic parking considering obstacle behavior
Authors: Gan Nianfei , Zhang Miaomiao , Zhou Bing , Chai Tian , Wu Xiaojian , Bian Yougang 
Published: July 2022

Purpose
The purpose of this paper is to develop a real-time trajectory planner with optimal maneuver for autonomous vehicles to deal with dynamic obstacles during parallel parking.

Design/methodology/approach
To deal with dynamic obstacles for autonomous vehicles during parking, a long- and short-term mixed trajectory planning algorithm is proposed in this paper. In long term, considering obstacle behavior, A-star algorithm was improved by RS curve and potential function via spatio-temporal map to obtain a safe and efficient initial trajectory. In short term, this paper proposes a nonlinear model predictive control trajectory optimizer to smooth and adjust the trajectory online based on the vehicle kinematic model. Moreover, the proposed method is simulated and verified in four common dynamic parking scenarios by ACADO Toolkit and QPOASE solver.

Findings
Compared with the spline optimization method, the results show that the proposed method can generate efficient obstacle avoidance strategies, safe parking trajectories and control parameters such as the front wheel angle and velocity in high-efficient central processing units.

Originality/value
It is aimed at improving the robustness of automatic parking system and providing a reference for decision-making in a dynamic environment.
Analyzing the inconsistency in driving patterns between manual and autonomous modes under complex driving scenarios with a VR-enabled simulation platform
Authors: Xu Zheng , Fang Yihai , Zheng Nan , Vu Hai L. 
Published: July 2022

Purpose
With the aid of naturalistic simulations, this paper aims to investigate human behavior during manual and autonomous driving modes in complex scenarios.

Design/methodology/approach
The simulation environment is established by integrating virtual reality interface with a micro-simulation model. In the simulation, the vehicle autonomy is developed by a framework that integrates artificial neural networks and genetic algorithms. Human-subject experiments are carried, and participants are asked to virtually sit in the developed autonomous vehicle (AV) that allows for both human driving and autopilot functions within a mixed traffic environment.

Findings
Not surprisingly, the inconsistency is identified between two driving modes, in which the AV’s driving maneuver causes the cognitive bias and makes participants feel unsafe. Even though only a shallow portion of the cases that the AV ended up with an accident during the testing stage, participants still frequently intervened during the AV operation. On a similar note, even though the statistical results reflect that the AV drives under perceived high-risk conditions, rarely an actual crash can happen. This suggests that the classic safety surrogate measurement, e.g. time-to-collision, may require adjustment for the mixed traffic flow.

Research limitations/implications
Understanding the behavior of AVs and the behavioral difference between AVs and human drivers are important, where the developed platform is only the first effort to identify the critical scenarios where the AVs might fail to react.

Practical implications
This paper attempts to fill the existing research gap in preparing close-to-reality tools for AV experience and further understanding human behavior during high-level autonomous driving.

Social implications
This work aims to systematically analyze the inconsistency in driving patterns between manual and autopilot modes in various driving scenarios (i.e. multiple scenes and various traffic conditions) to facilitate user acceptance of AV technology.

Originality/value
A close-to-reality tool for AV experience and AV-related behavioral study. A systematic analysis in relation to the inconsistency in driving patterns between manual and autonomous driving. A foundation for identifying the critical scenarios where the AVs might fail to react.
The expression of keratan sulfate in malignant melanoma enhances the adhesion and invasion activity of melanoma cells

Published: July 2022

AbstractMammals express a wide variety of glycans that include N‐glycans, O‐glycans, proteoglycans, glycolipids, etc. Glycan expression can modulate the cellular functions, and hence is strongly involved in the onset and progression of numerous diseases. Here, we report the relevance of the ectopic expression of keratan sulfate (KS) glycan chains in human malignant melanomas. Using a human melanoma cell line, we found that the KS enhanced the invasiveness of the cells but caused no change in the growth rate of the cells. The phosphorylation of paxillin, a focal adhesion‐associated adaptor protein, was strong at the region where KS was expressed in the melanoma tissues, indicating that KS stimulated the phosphorylation of paxillin. We also observed that KS enhanced the adhesion of melanoma cells and this was accompanied by a greatly increased level of phosphorylation of paxillin. These data suggest that the expression of KS contributes to the development of malignant phenotypes such as strong cell adhesion and the invasiveness of melanoma cells.
Annual variability in the sound acorn production of Quercus serrata is regulated by a seed‐predatory weevil in western Japan
Authors: Hirayama Kimiko , Mizo Kenta , Tatsuno Manaka , Yoshikawa Mizuki , Tachikawa Chieri 
Published: July 2022

AbstractIn plants, processes from flowering to seed maturation are influenced by various factors, including weather conditions, resource supply, and damage inflicted by seed predators, that collectively contribute to annual variability in seed production. To identify the important factors associated with sound acorn production in Quercus serrata, from 2014 to 2020, we investigated the demographic processes from flowering to acorn maturation in six individual trees within a stand in a warm‐temperate secondary forest in western Japan. We found that the annual production of female flowers was positively correlated with the difference in April temperatures between successive years. However, their fluctuation was low and unaffected by either seed or flower production in the previous year. Compared with those of female flowers, the annual variability in sound acorn production within an individual was significantly higher and more synchronized. Key factor analyses revealed that reproductive losses due to the oviposition and sap‐sucking activities of Mechoris ursulus were the most prominent factors contributing to the observed annual variation in total predispersal losses at an individual level, and their effects were synchronized among individuals within a population. Survival from female flowering to sound acorn maturation was strongly predicted by the temperature in June, which corresponds to the period of adult M. ursulus emergence. Our findings indicate that the damage inflicted by the main seed predator during the predispersal stage can sufficiently regulate the sound acorn production patterns in Q. serrata that appear to resemble masting behavior (the highly variable and synchronized production of acorns within individuals).
Belief and higher‐order belief in the centipede games: An experimental investigation
Authors: Wang Yun 
Published: July 2022

AbstractThis paper experimentally explores the epistemic conditions behind people's non‐equilibrium behaviour in the centipede games. We propose a novel design of laboratory experiment to elicit people's first‐ and second‐order beliefs regarding their opponents' choices and beliefs. The measured beliefs, together with the choice data, help us to estimate people's level of rationality, belief of rationality and second‐order belief of rationality. To examine how these epistemic variables are affected by the social‐efficiency property of the classic increasing‐sum centipede game, we revisit the constant‐sum centipede and compare the measured epistemic conditions from the constant‐sum with those from the classic centipede. We find that people's non‐backward induction behaviour may be attributed to the diffusion of beliefs and higher‐order beliefs in the increasing‐sum centipede. We consider a behavioural model in which people's preferences for social efficiency are incorporated into the extended utility maximization problem. Our analytical and estimation results indicate that the presence of efficiency‐oriented players and people's belief towards the uncertain portion of such type of players may play a part in the non‐backward‐induction outcomes in experimental centipede games.
