abstract = {This paper presents an autoethnography of 3 years of learning to play the theremin, an instrument lacking tangible feedback. While the theremin is typically invoked in HCI to emphasize the importance of the tactile modality, we interrogate how I, the player, attained musical proficiency without touch. Through a thematic analysis of 235 journal entries, our study distills my strategies for navigating the instrument as well as my personal transformations along the way. We discover that without touch, accurate and musical playing on the theremin relies on continuous auditory feedback, proprioception, and imaginative processes. We discuss challenges and opportunities for embodied and tangible interaction in light of these findings.},

abstract = {Dental CAD/CAM has been modernised in the last years thanks to digital intraoral scanners (IOS) and additive manufacturing machines, which are increasingly used in the dentistery. Stl files obtained with IOS are the first step for the digital manufacture of dental prostheses. Their quality, characterized with precision and accuracy are the key terms to guarantee efficiency in patient care. However, several parameters influence them, such as the environment (temperature, brightness, etc.), the practitioner (level of expertise, fatigue, handling the scanner, etc.), the patient (tongue, head, saliva, complex shapes, etc.) and the scanner (speed, rate, resolution, starting point, trajectory, tip, etc.).
In the medical sector, the use of robotics is getting more common to improve precision in surgery for example. In this project, a cobot i.e. a collaborative robot (UR5e from HMI-MBS), combined with the Care Stream CS3800 IOS, one of the most interesting scanners on the market are used to ensure repeatability of the experiments and to quantify the impact of the environmental factors. Then results are compared in a same protocol with files obtained manually by a practionner.
In the study, we assume that we are working on the restoration of a molar for an adult with standard dentition using a sphere (canonical form) whose material and diameter are similar in size to an adult molar. Given the complex shapes of the tooth and multiple parameters involved, initial assumptions are made. Indeed, we assume we are working in a dentist's surgery environment and using only the wireless side with its standard tip for the scanner.},

abstract = {Objective: This study aims to assess the accuracy of dental arch models printed with different vat photopolymerization technologies SLA (stereolithography), DLP (digital light processing) and LCD (liquid crystal display) while considering different resin types and layer thicknesses.
Materials and methods: Based on a STL file of a dental arch, 80 models were printed flat on the build plate using the specific resins from a SLA printer (Draft V2 (DR) and Grey V4 (GR) resin on Form 3+ Auto, Formlabs), a DLP printer (printed with different resin (Die and model 2 (DM) on Pro95S, SprintRay), a LCD printer (Aqua-Gray (AG) on Sonic Mini 8Ks, Phrozen) and according to the different layer thicknesses recommended by the manufacturer for each resin. The production time (printing and post-processing) of 10 models printed with the same resin and layer thickness was recorded. The STL files of the printed models were obtained after scanning with the highest precision program of a desktop scanner. A same mesh processing of the 80 STL files and the initial STL file was performed for better comparison. Accuracy was assessed as the area of valid distance between the STL of a printed model and the initial STL file following a best fit comparison with a 3D analysis software (Zeiss Inspect).
Results: The production time was the fastest with the DLP printers. Only the resin DR200 (Draft V2 resin printed with a layer thickness of 200?m) had an equivalent production time as DM100 (Die and model resin printed with a layer thickness of 100?m). Accuracy amongst the different printed models for a specific resin and a given thickness layer significantly increases according to the following sequence: AG50 < DM50 < DM170 < DM100 = DR100 = DR200 = GR100 < GR50.
Conclusion: A SLA printer has the best accuracy over the DLP and LCD. It's possible that hardware of the vat photopolymerization technologies may explain the differences in accuracy.
Clinical relevance: Within a dental laboratory seeking to optimise both accuracy and efficiency, mass printing of models with a layer thickness of 200?m on an automated SLA printer can be recommended.},

We argue that two opposing channels may exist in this relationship: either climate risk has a negative effect stemming from increased demand for sustainable or climate-resilient projects that enhance creditworthiness, or climate risk has a positive effect arising from heightened climate uncertainty and risk aversion, leading to credit self-rationing among SMEs. Our findings reveal that heightened climate risk prompts SMEs to self-ration credit, leading to higher probabilities of discouraged borrowers. Our research deepens the understanding of the impact of climate risk on credit-related decisions, stressing the need for proactive measures to integrate climate risk assessments into regulatory frameworks and lending practices. The findings underscore the vulnerability of SMEs to climate risk, emphasizing emphasising the importance of tailored support mechanisms for economic resilience.},

The use of a mobile recycling application is evaluated with regard to its media richness with a sample of 12 539 users in Italy. The research is developed during the COVID-19 pandemic, at a time when users have become more environmentally conscious and aware of plastic pollution. This time period has also seen an increase in the use of mobile applications, which provide social engagement and other benefits. Although it has encouraged new research on recycling behavior and how environmental messages are spread, as far as we know, no research has included a specific technology, such as mobile applications. Through the lens of consumer social media engagement behavior, it has emerged that media richness has a positive correlation with user engagement and recycling behavior. Theoretically, the research offers a novel technological tool worthy of further exploration in the fields of management and engineering. New practical insights are offered in terms of best practices for strengthening the relationships between companies and their clients. As users become more accustomed to social technologies, those technologies may help to establish responsible consumption patterns.},

abstract = {While the notion of business ethics has historical roots, previous research endeavours have refrained from consolidating the existing body of knowledge on the intersection of business ethics and society. This hesitance is attributed to the intricate and diverse nature of such studies. Thus, there is a gap in the literature on synthesizing the intimate relationship between business ethics and society. This gap in research serves as the impetus and motivation for the current investigation. However, limited empirical studies are found to have been conducted in the allied areas and there are limited studies that map business ethics and society in an extensive manner. In this context, this study systematically reviewed 87 scholarly works spanning a period of over 20?years in the realm of business ethics concerning society by considering articles included in the Scopus and Web of Science databases. Through the outcomes of this inquiry, an integrative and comprehensive framework detailing the interplay between business ethics and society at individual and organizational levels is introduced, with the potential to guide forthcoming scholars and practitioners in their pursuits. In this study, themes including employees' ethical behaviour, manufacturing strategy and ethics, leadership dynamics, consumer trust and so on have not been considered as critical societal dimensions that have not been included.},

In Phase 1, this study focused on the advanced manufacturing context of Italy by surveying 540 managers to develop a multiple regression model and test six different GHRM practices as the hypotheses. In Phase 2, qualitative data analysis was analyzed. Our findings highlighted that GHRM practices connected with awards and compensations did not affect green performance. Conversely, a correlation was observed between achieving green performance and practices such as training, aligning management with the company's strategic environmental goals and objectives, involving managers in the process of defining the goals and objectives, and the green reputation of the company and the managers who can act as environmentally responsible leaders. This study extends social exchange theory and opens new avenues for further research and proposes several practical suggestions for practitioners.},

This study analyzes the on-time order fulfillment problem for an autonomous order picking and delivery system in online retailers. We draw inspiration from Meituan's pioneering solution, "Autonomous micro-warehouse and delivery", in which micro-warehouse robots are used for order picking, and delivery robots are used for transporting orders to destinations. We investigate the dynamic priority policy to facilitate efficient task allocation for different order classes, which ensures prompt service for high-priority orders and attentive handling of low-priority orders with extended waiting times.
We develop a dynamic priority-based queueing network to model the system and propose an AMVA-based approximation method to solve it. Numerical experiments validate the analytical model, providing valuable insights into operational efficiency. This paper makes the following contributions: (1) We are among the earliest to investigate autonomous order picking and delivery systems using queueing networks. We propose a new approximation method to solve the proposed nested queueing network with dynamic priority. (2) We outline procedures for determining the optimal numbers of micro-warehouse robots and delivery robots, considering the order fulfillment time requirements. (3) We find that the use of dynamic priority can improve the on-time order fulfillment rate.},

To test this theory, we employ an original dataset sourced from the Mexican 2018-2021 Chamber of Deputies, which comprises the inaugural group of Congress members allowed to seek reelection after a 90-year prohibition within the context of a transforming party system marked by the diminishing electoral attractiveness of traditional parties. Our findings carry significant implications for comprehending how party leaders recognise and reward legislators who effectively safeguard the party's interests and uphold its reputation inside the halls of Congress.},

In particular, with the growing development of crowdfunding models, scholars and practitioners are questioning how backers can cocreate value by funding new entrepreneurial initiatives through digital platforms dedicated to this new form of financial support. Therefore, positioning this article in the knowledge and engineering management literature, the current research explores whether two subdimensions of value cocreation (VCC), knowledge sharing and interaction, may help to understand backers' intention to participate in a reward-based crowdfunding (RBCF) campaign. In particular, using the partial least square structural equation modeling approach on an original sample of 3574 backers, in this article, we find that knowledge sharing, understood as backers' expertise as well as the preparedness of the proponent team, and the interaction between the campaign actors contribute to explaining backers' participation in an RBCF initiative. The research supports the relevance of backers' engagement in terms of VCC as an experiential benefit for the success of an RBCF initiative. From this perspective, our study suggests that both entrepreneurs and platforms should consider VCC in the design and setting of RBCF campaigns.},

Given the prevalence of COVID-19 cases and the extensive volume of patient records lacking labels, this communication underscores our unique approach?conducting the first study on COVID-19 case diagnosis in an unsupervised manner. Our work operates under the assumption of prior knowledge regarding the number of classes, such as COVID-19, pneumonia, and normal, in a case study.
By adopting an unsupervised learning paradigm, we leverage the wealth of unlabeled data, reducing dependence on human experts for annotating numerous images. This paper introduces an enhanced version of a recent direct method where non-negative cluster indices and spectral embeddings are jointly estimated. Beyond the inherent advantages of this method, our proposed model introduces improvements through two additional types of constraints: (i) ensuring consistent smoothing of cluster labels across all views and (ii) imposing an orthogonality constraint on the matrix of cluster assignments. The efficacy of the proposed method is demonstrated using the public COVIDx dataset with three classes, showcasing promising results in categorizing radiographs. The proposed approach is tested on other public image datasets to assess its effectiveness.},

More specifically, we test whether such facilities positively affect the competitiveness of the ports, which would be an additional incentive to drive the transition to alternative fuels. Using multilevel regressions and propensity score matching on LNG-fueled vessel movements in the Baltic Sea Region in 2019, we found no significant effect of LNG bunkering infrastructure on port competitiveness, measured by port choice probabilities expressed by vessels. Although our findings indicate that ports do not gain a competitive advantage in the short-term, we do not rule out potential gains in the long-term. Policy intervention is desirable in the short-term to maintain incentives for port investments.},

abstract = {Haptic exoskeleton gloves are a widespread solution for providing force-feedback in Virtual Reality (VR), especially for 3D object manipulations. However, they are still lacking an important feature regarding in-hand haptic sensations: the palmar contact.
In this paper, we present PalmEx, a novel approach which incorporates palmar force-feedback into exoskeleton gloves to improve the overall grasping sensations and manual haptic interactions in VR. PalmEx's concept is demonstrated through a self-contained hardware system augmenting a hand exoskeleton with an encountered palmar contact interface -- physically encountering the users' palm.
We build upon current taxonomies to elicit PalmEx's capabilities for both the exploration and manipulation of virtual objects.
We first conduct a technical evaluation optimising the delay between the virtual interactions and their physical counterparts.
We then empirically evaluate PalmEx's proposed design space in a user study (n=12) to assess the potential of a palmar contact for augmenting an exoskeleton. Results show that PalmEx offers the best rendering capabilities to perform believable grasps in VR.
PalmEx highlights the importance of the palmar stimulation, and provides a low-cost solution to augment existing high-end consumer hand exoskeletons.},

This result is remarkably robust after conducting a difference-in-differences analysis that exploits brokerage closures and mergers as an exogenous decrease in analyst coverage, as well as using an instrumental variable approach. The positive influence of analyst coverage on corporate environmental disclosure is particularly evident for firms that cause high environmental damage, firms with low information asymmetry and those followed by analysts with superior experience, accuracy and reputation. Taken together, our empirical findings provide new insights into the bright side effect of analyst coverage on corporate environmental-related activities.},

abstract = {CAD/CAM technologies have driven substantial progress in dentistry, replacing traditional plaster by a digital chain mainly using STL files. The first step in this chain is the digitization made by IOS, which allows a transition from the real world to a digital model.
Initially, the STL files issued of the IOS's intended as a support to design the prostheses. They also have proven valuable for comparing geometric and dimensional differences between two files, aiming determining the quality of IOS's or/and also between different dental protocols.
Following a bibliographic study of the scientific literature, two main methods of comparing by superimposing STL files emerge: 1) the use of a best-fit algorithm and 2) adding physical geometric elements (landmarks), such as spheres, cylinders and cones, on the dentition to be scanned.
On one hand, best fit algorithm relies on the scanned surface range. When applied to full-arch models with additional surfaces like part of palate, gum, it results in a loss of precision. Also, it is necessary to take into account the biases of the variability of the scanned surfaces, the complexity of the geometry, and its sensitivity to digitization errors. However, it's a simple and readily applicable method. For instance, it enables to create colored maps illustrating differences between the files, determine minimum and maximum recorded values, and compute the standard deviation.
On the other hand, using geometric landmarks allows us to measure deviations, linear distances, spatial distortion and cross distances, between particular points of the landmarks (centers of spheres, head of cones, cylinders axis). Finally, overall or local trueness computation is possible. This method ranging from measuring arch opening to torsion allows great precision and repeatability, but is very difficult to implement in vivo.
My research works focuses on introducing an effective protocol solution. This involves proposing a hybrid post-processing method to integrate virtual reference geometries directly onto scans. Ultimately, this method aims to achieve the same results as landmark-based approaches, either without explicit landmarks or through a combination of localized best fit and geometric landmarks.},

The empirical application to the US agriculture sector (1948-2017) further suggests that the SPFI is a (superior) alternative to the traditional Malmquist DEA, especially in dealing with unbalanced panel or time series data when price data are unknown.},

This study examines how donor confidence in digital technologies impacts antifragility in HSCs through their application in sourcing, material flow, and distribution, with trust in digital technologies and perceived effective digital technology governance as moderating factors. Using resource dependence theory, data from 296 NGOs were analyzed with partial least squares-based structural equation modeling (PLS-SEM). The findings show that digital technology application is crucial for building an antifragile HSC and that donor confidence and trust in digital technologies are essential.

Drawing on regulatory focus theory, we contend that workaholism (a pull factor) and job insecurity (a push factor) constitute two critical antecedents that predict sustained
employability. Moreover, we investigate the mediating roles
of job crafting and presenteeism. To explain and test these
predictions, we employed a mixed-methods approach and
conducted two studies. Study 1 was an exploratory study to
explore the hidden motives behind presenteeism that can
predict sustained employability. The findings (themes) from
this study guide the conceptual framework tested in the second study. In Study 2, we conducted a field survey across
two waves on 498 employees from private sector educational institutions. The results reveal that both the pull factor
(workaholism) and push factor (job insecurity) predict sustained employability through two distinct paths. Furthermore,
promotion-oriented job crafting and approach-motives
presenteeism serially mediate the relationship between
workaholism and sustained employability, whereas preventionoriented job crafting and avoidance-motives presenteeism
serially mediate the relationship between job insecurity and
sustained employability. These findings offer valuable
insights for organizations and HR managers, enabling them
to create more supportive and adaptive work environments
that align with varied employee approaches to sustained
employability.},

We did so with the aim of answering the following question: how do geopolitics affect the bargaining balance of power between a Russian MNC and a host country?
Design/Methodology/Approach - We employed the Discourse Analysis methodology to identify the key players in the bargaining process and illustrate the evolving bargaining process.
Findings - We demonstrated that, over time, the shift in power from the Russian MNC to the host government had not merely been the result of the increase in committed MNC assets in the host country but, rather, of a geo-political chess game involving the Russian government, NATO, and the EU. By extending the OBP model with geopolitics, we found that a political agenda can influence the outcome of a bargaining process.
Originality - We extended the OBP model to illustrate the complex interaction between an emerging market MNC and an emerging host country government, indirectly influenced by two supranational organizations?the EU and NATO.},

Prior studies suggest that public attention brings scrutiny that reduces selective disclosure by increasing the risk of getting caught (the floodlight thesis). The impression management literature, however, suggests that public attention offers the possibility of broad-based image benefits from the disclosure of strategically filtered data (the spotlight thesis). Panel regressions with Trucost data from 2008-19 provide overall support for the spotlight thesis as well as a negative moderator, environmental damage. Results also point to an underlying mechanism: Companies receiving public attention disclose a larger number of environmental metrics, but not ones that, altogether, represent more environmental damage, a tactic that we call strategic fluffing.},

abstract = {Maraging steels are commonly used in industries that require high precision due to their excellent mechanical properties, including high strength, toughness, formability, weldability, dimensional accuracy, and formability. These steels are characterized by a typical martensitic structure obtained through aging heat treatments. The trend towards using high-strength steels in the industry has led to the need to optimize mass while maintaining good mechanical properties for specific applications. Electron beam melting (EBM) is an additive manufacturing technique that offers several advantages over traditional methods. It enables the production of complex geometry parts in small series and the creation of prototypes from CAD models. However, optimizing the parameters of the EBM process is a major challenge due to the complex physical phenomena involved, such as phase and material changes. This study investigates the impact of three EBM process parameters (layer thickness, electron beam power, and preheating temperature) on the hardness of maraging steel. The findings contribute to the improvement of the EBM process and the production of high-quality components. These components have applications in various sectors, including medical, automotive, and aerospace, highlighting the importance of this research for a wide range of advanced applications.},

Neither firm strategies and processes, nor IB theories and models have yet caught up with increasing politicization. In this paper, we pose three questions: why are firms increasingly affected by politics in their internationalization? How do firms respond to the increasing role of politics? And finally, how do theories considered foundational across IB research incorporate politics? We discuss how the resource-based view, transaction cost economics, institutional theory and agency theory relate to politics. Further, we identify eight predominant dimensions where firms are affected by politics. Finally, we suggest that the increasing role of politics can be ascribed not only to specific macro-level historical events but also to more fundamental micro-level transformations in prevalent institutional configurations of firms' value adding activities.},

abstract = {Brand identity helps customers to identify, as well as distinguish alternative competitive brands. If there is a consistent marketing strategy and consistent messaging, brand identity remains consistent, which helps in improving sales management and generating better revenue for the brand. In this digital era, there are various digital marketing tools and capabilities to improve brand identity, which help in establishing close association with customers to influence their purchasing decisions. However, we have limited understanding of the antecedents of brand identity in the digital era, and how the moderating role of consumer belief in brands could influence their purchasing decision making process. In this context, this study aims to determine the antecedents of brand identity in the digital era, and to examine if there is any moderating impact of consumer belief in brand (CBB) on consumer purchase decision (CPD). Based on the resource-based view and social identity theory, a theoretical model has been developed. Following the survey responses of representatives from 302 organizations/brands, the covariance-based structural equation modelling validates our model. Our analysis affirms that e-WOM, digital infrastructure, skilled manpower, and digital marketing capability positively impact on developing brand identity, which influences sales strategy differently in different situation to influence CPD, where CBB plays a moderating role. The study results have been derived by analyzing the inputs of the respondents based out of India which invited external validity issue and it has been considered as one of the limitations of this study.},

abstract = {Despite the two sides of deviant behaviors and the fact that knowledge brokers are sometimes presented in a negative light due to their unique position, this article unveils from an innovation perspective how these two intricate individual-level concepts bring positive outcomes in complex environments. While previous work has highlighted the positive impact of constructive workplace deviance on organizations and their members, research on the antecedents of such deviance is scarce. We use knowledge brokers as an unexplored and pertinent means of enacting innovative constructive deviance. Indeed, knowledge brokering supports innovation by connecting, recombining, and transferring disconnected pools of ideas. A case study of a high-tech company was conducted. We focused on three B2C and B2B co-creation projects as one of the main open innovation strategies. The results suggest that knowledge-brokering activities with customers or partner firms enact innovative constructive deviance in different ways and accelerate creativity and innovation within the organization. This paper contributes to the debate on deviant behaviors and brokering activities within the open innovation paradigm. We enrich the microfoundational perspective of the open innovation literature, shed light on the determinants of innovative constructive deviance, and provide empirical evidence of the relationship between brokering activities and deviant behavior. On a managerial level, the findings suggest that knowledge-brokering activities among multiple stakeholders foster innovative behaviors within co-creation projects.},

abstract = {Allocating carbon emissions abatement (CEA) is crucial for reducing carbon footprint of organizations (or decision-making units, DMUs) and mitigating global warming. However, discrepancies often arise among DMUs regarding CEA allocation. This study introduces a dynamic bargaining game approach to address the issue under the nonparametric production frontier analysis framework. Our approach employs an iterative process, allowing each DMU to propose its individual preferred CEA allocation proposal in each iteration. Subsequently, dynamic negotiations among the DMUs occur, leading to the eventual consensus on the CEA allocation result. Our theoretical analysis demonstrates that, at the end of the dynamic bargaining game, all DMUs will converge on the same CEA allocation result, termed as the consensus CEA allocation result. This agreement is reached despite each DMU customizing its individual CEA allocation proposal to suit its own interests. Moreover, we prove that this consensus CEA allocation result represents a Nash equilibrium solution, thereby ensuring its stability and acceptance among all DMUs. Finally, we provide a simple numerical example and a case study of CEA allocation across 27 European Union countries to illustrate the usefulness of our approach and compare it with prior CEA allocation approaches.},

Short-term market reactions surrounding award announcements are significantly positive, whereas the valuation of firms with awarded CEOs is greater than that of (matched) firms with nonawarded CEOs. We explore the channels through which government awards create value and find evidence that they provide awarded CEOs and their firms with increased political access. We also observe that government awards are associated with better corporate governance in that awarded CEOs are more likely to be fired for poor performance. The negative effects that have been documented for media awards and are associated with CEOs' superstar status do not seem to apply to state awards.},

journal = {Qualitative Research in Organizations and Management},
abstract = {Purpose - The purpose of this article is twofold. Its first objective is to bring to the fore the unexplored and neglected origins of social exchange theory (SET) to critique this body of conjecture. This unearthing is illustrated through focusing on the way the theory was developed and how this development was mischaracterised in literature. Its second objective is to invoke the methodological assemblage of ANTi-History and the ?close reading? notion using multiple archival sources to demonstrate their usefulness within the
critical qualitative method debate.
Design/methodology/approach - The historic character of management and organization studies is exemplified through utilizing a combination of textual sources to examine how SET emerged from within the human relations school of thought throughout much of the twentieth century. Specifically, an array of sources
(including archival data) is deployed and closely examined to trace how SET formed and became prevalent in organizational studies over the last decades.
Findings - SET is not only indebted to the human relations movement in general and to Elton Mayo's work in particular (as is well-known), but also to logical positivism and behavioralist-school psychology. As such, Homans' work marked the beginning of a new era in organizational behavior research.
Originality/value - The article highlights the role of historical analyses in interpreting mainstream constructs in organizational behavior. In doing so, it reveals how critical qualitative research leads to understanding some shortcomings of a theory and indicates potential remedies.},

journal = {Journal of Applied Accounting Research},
abstract = {Purpose - The purpose of this paper is to examine the effect of chief executive officer (CEO) overconfidence on
earnings quality and the moderating role of ownership structure as a crucial corporate governance device.
Design/methodology/approach - The paper uses the generalized method of moments (GMM) estimation
method to test our models on a sample of 335 French companies between 2009 and 2020, i.e. 4,020 observations.
Findings - The results show that CEO overconfidence negatively affects earnings quality. This result
supports the predictions of behavioral finance theory and suggests that CEO overconfidence is a behavioral
bias that affects the quality of earnings. The authors also examined the effect of different types of ownership
structures on this relationship. The results show the significant role of controlling shareholders, owner-
managers, families and institutional investors in mitigating the negative effect of CEO overconfidence on
earnings quality.
Research limitations/implications - This paper has some limitations. First, other types of ownership
structures could have been analyzed such as state ownership. Second, we ignored the role of the board of
directors as an important governance mechanism in controlling overconfident CEOs' actions.
Practical implications - Companies should be aware of the potential risks associated with CEO
overconfidence, which can compromise the faithful representation of earnings. This highlights the importance
of effective monitoring and internal controls to detect and prevent such practices, which involve the role of
ownership structure.
Originality/value - This paper addresses the effect of CEO overconfidence on earnings quality and provides
new evidence on the role of different ownership structure types in shaping this relationship. Additionally, this
paper sheds new light on how overconfident CEOs may behave in challenging times.},

journal = {Journal of Small Business and Enterprise Development},
abstract = {Purpose - This study aims at assessing entrepreneurial business performance (EBP) from dynamic capability
(DC) and technology-organization-environment (TOE) framework perspectives, taking support from
crowdfunding.
Design/methodology/approach - With the inputs from the literature, supported by TOE framework and
the dynamic capability view (DCV), a model has been proposed. This model has been tested by the factor-based
partial least squares structural equation modeling (PLS-SEM) technique through a survey and quantifying the
responses of 406 respondents on a five-point Likert scale has been used.
Findings - The study has found that crowdfunding support (CFS) has an effective influence on the
improvement of EBP. Also, the DC supports to improve the EBP. Environmental dynamism (END) has also a
critical role in impacting business performance.
Research limitations/implications - Crowdfunding involves investors who have a similar interest in the
business, close friends, family members, venture capitalists, investment groups, etc. Thus, the proposed model
can be used by these stakeholders for investment purposes as well as for improving EBP. This study is a cross
sectional research work which has limitations. Moreover, the sample size of this project is limited and did not
include global respondents, Thus, the findings of this study cannot be generalizable which is another limitation
of this study.
Practical implications - Crowdfunding involves investors who have a similar interest in the business, such
as close friends, family members, venture capitalists, investment groups, etc. Thus, the proposed model can be
used by these stakeholders for investment purposes as well as for improving EBP. The study can help
policymakers understand the importance of crowdfunding in promoting entrepreneurship activities in a
region, which helps in the economic development of that region.
Originality/value - This research work enriches the extant literature in the fields of crowdfunding and
investment, DC and entrepreneurship. Not many studies have dealt with the issues of CFS for the improvement
of EBP. Hence, this study may be considered novel. Moreover, the proposed research framework related to
crowdfunding possesses a high predictive power. This makes the study unique.},

The outcome of our study proposes a three?step approach unveiling blockchain technologies, supply chain finance strategies and enablers of circular economy contributing to 10R principles. Our study underscores how these cases across the globe can serve as valuable examples to other organisations, encompassing sectors from manufacturing to core?service based such as e?commerce. These sectors involve complex supply chains, and hence, blockchain?enabled supply chain finance strategies can be a solution to foster a circular economy.

Damage modeling was used to evaluate the behavior of hydrogen tanks to high pressure. A practical approach, coupling a finite element method (FEM) simulation and machine learning algorithm (ML), is suggested. The representative volume element (RVE) was used in association with a choice of a behavior law and a damage law as an input data. Algorithms for ML classification such as K-nearest neighbors (k-NN) and a special k-NN with a dynamic time warping (DTW) metric were used. The hierarchical clustering through dendrograms visualizations allowed to exhibit the impact of composite parameters in relation to fiber, matrix properties and fiber volume fraction on the strain degradation under external static pressure. Continuing this, the optimum RVE which shows a low degradation value will be exhibited.},
