It also examines the mediating effects of customers' perceived flow and engagement between attitudes and customer's intention to use smartphone-based online gaming. Furthermore, customers' cognitive involvement was also examined as a moderator in between attitude and perceived flow. The data were analysed using a dual-stage hybrid method embedded with PLS-SEM and ANN. A sample of 688 smartphone-based online game players was surveyed, and the results support the notion that customers' attitudes, considered as a formative construct, significantly influence intention to use smartphone-based online gaming. The study further confirms that perceived flow and customer engagement mediate the relationship between attitudes and intention to use smartphone-based online gaming. The study also identifies the role of cognitive involvement as a significant moderator in between customers' attitudes and perceived flow. Contributions for both theory and practice are presented in the concluding sections.},

The samples for the online survey were selected from food supply chain (FSC) firms. Hypothesis testing was performed and findings indicate that lower-order capabilities, such as adaptability, agility, and alignment capabilities, play a critical role in developing dynamic capability, that is, digital technology capability, which helps in achieving superior operational performance. However, innovative lean management capability plays a partial mediation role between digital technology capability and operational performance. A moderating role for continuous learning and overall satisfaction of employees was also supported. FSC firms should consider these factors to enhance operational performance in a dynamic business environment.},

abstract = {In a changing business environment, firms encounter significant challenges to fulfill sustainable development goals. However, firms can make substantial progress by adopting regenerative approaches grounded in circular economy principles, enabling them to effectively pursue sustainable development objectives such as responsible production and consumption (goal 12), climate action (goal 13), and the preservation of life on land (goal 15). However, there is a scarcity of research studies that offer guidance to top supply chain (SC) executives, aiming to enhance their environmental focus and enhance the SC viability through regenerative SC practices. This study employed the philosophical perspective of the natural resource-based view. Advancing the SC literature, it tested a theoretical model to investigate the relationship between the political skills and SC analytics skills of top SC executives and the environmental orientation of SCs. Additionally, it examined the direct and indirect (via regenerative SC) relationships between a firm's environmental orientation and SC viability. This study also tested the moderating role of a firm's artificial intelligence-driven big data analytics culture in these relationships. Applying a mixed-methods approach, the study derived a theoretical model to link the aforementioned constructs. Apart from a qualitative investigation, data were also collected through a questionnaire-based survey from 375 samples. The results indicated that the relationship between the political skills and SC analytics skills of top SC executives toward the environmental orientation of SCs is significant. Furthermore, they indicated that a firm's environmental orientation is positively related to a regenerative SC, which in turn enhances SC viability. The findings also provided evidence that a firm's AI-driven big data analytics culture enhances the strength of these relationships. The current study extends the knowledge base by integrating the two unique concepts of digitalization and circular economy.},

abstract = {Rapid industrialization and global supply chains have magnified industrial activities' carbon footprint, resulting in environmental hazards. Several countries have magnified their efforts to reach carbon neutrality goals. The increased attention to carbon-neutral goals has been enabled by United Nations (UN) calls for a carbon-neutral economy. In this context, supply chains will have greater responsibilities to reduce the network's carbon footprint. To achieve carbon neutrality goals, decision-makers must be well-informed and facilitated with suitable theoretical frameworks. In literature, the adoption of intelligent technologies is suggested to construct efficient and smart supply chains. However, there are uncertainties regarding the impact of this transformation on the carbon neutrality goal. The present study caters to the uncertainties by discussing its potential impact on carbon neutrality goals and how to use adopted technologies to achieve the same. A list of 11 potential strategies is identified and modelled to provide a strategic roadmap for smart supply chains' adoption. The proposed framework aims to facilitate carbon neutrality goals. The findings indicate that decision-makers must pay significant attention to circular economy practices. Additionally, green transportation is an impactful area with significant potential to support carbon neutrality goals. Critical insights have been extracted regarding stakeholders' training and process innovation. The study findings can help decision-makers achieve carbon neutrality goals.},

abstract = {Although the circular economy is commonly used among industries in developing countries to achieve carbon neutrality targets, its impact on social sustainability must be clarified. Stakeholders (for instance, community stakeholders) have been observed to be unaware of the focal firm's circular supply chain activities. Because this gap has not been generally reflected in the literature, it is critical to perform an empirical study to bridge the gap between theory and practice. The goal of this research was to determine whether new technologies such as big data and predictive analytics might influence an organization's propensity to share information related to circular economy practices with stakeholders as well as to increase connectivity with those stakeholders in the Industry 4.0 era. We also investigated whether these actions could increase stakeholder trust and engagement and social sustainability as a result. We tested our theoretical model using samples from food supply chain firms in South Africa. Confirmatory factor analysis was conducted using WarpPLS 7.0 software. The findings show that firms that deploy big data and predictive analytics are more likely to share information related to the circular economy with stakeholders and that these firms are also well-connected with those stakeholders, resulting in increased trust and engagement. This, in turn, contributes to the social sustainability of supply chains. Our research has made a significant contribution by encouraging a theoretical debate regarding the willingness to share information regarding the circular economy and the social sustainability of the supply chain.},

Unlike the conventional projection methods, the viscosity is not dropped in the last step allowing to enforce the full original boundary conditions on the end-of-step velocity which eliminates any concerns about the numerical boundary layers. We carry out a rigorous error analysis and provide a full first-order error estimate for both the velocity and pressure solutions in the relevant norms. Numerical results are presented for two test examples of non-

resulted in a decreased immune cell infiltration into the spheroids. Moreover, the presence of cortisol deregulated the normal levels of the pro- and anti-inflammatory cytokines IFN-?
and IL-10. We present an individual-based model to explore the interaction dynamics between tumour and immune cells under psychological stress conditions. With our model,
we explore the processes underlying the emergence of different levels of immune infiltration,
with particular focus on the biological mechanisms regulated by IFN-? and IL-10. The set-up of numerical simulations is defined to mimic the scenarios considered in the experimental
study. Similarly to the experimental quantitative analysis, we compute a score that quantifies the level of immune cell infiltration into the tumour. The results of numerical simulations indicate that the motility of immune cells, their capability to infiltrate through
tumour cells, their growth rate and the interplay between these cell parameters can affect the level of immune cell infiltration in different ways. Ultimately, numerical simulations
of this model support a deeper understanding of the impact of biological stress-induced mechanisms on immune infiltration.},

To fill the lacuna in the existing literature, this study examines the relationships between corporate ethical identity, corporate brand identity, social and environmental performance. The study uses a deductive research approach and develops hypotheses which are further tested using variance based structural equation modeling. The study offers a distinctive contribution to ethics theory and stakeholder theory by showing that developing an ethical identity requires more than just adhering to moral guidelines and upholding open communication. Companies must show that they are ethically responsible towards society. The study provides evidence of the influence corporate brand identity has on environmental and social performance.

Design/methodology: We developed and tested a mediated moderation model. The study hypotheses were tested
with partial least squares structural equation modeling techniques.
Findings: Results from 309 medical representatives supported the study hypotheses, indicating that leader humility
is related to employee voice via intention to share knowledge, and this relationship is stronger for shortertenured
employees than for longer-tenured ones. The study also provides implications for both theory and
practice.
Practical implications: The study provides empirical evidence in support of the positive effect of leader humility on
employee voice. Therefore, we suggest that executive administration should pay particular attention to promoting
humility in leadership to appropriately manage extra-role behavior such as employee voice.
Originality: Recently, leader humility has attracted scholarly attention in organization studies. It is considered a
key antecedent of employees' extra-role behavior and a contextual factor that is associated with many positive
employee and organizational outcomes.},

This study explores both the direct impact of economic policy uncertainty and coal price on carbon prices as well as the indirect impact of economic policy uncertainty on carbon prices through coal prices by utilizing the DCC-GARCH model and the NARDL model. The findings indicate that the dynamic correlations between coal prices and the CEPU are always negative and that those between the price of carbon and the CEPU vary by area. Meanwhile, the dynamic correlations between coal and carbon prices are only positive in Shenzhen and Beijing. Both coal prices and economic policy uncertainty produce asymmetrical impacts on carbon prices. Some policy implications are provided for developing the carbon markets in light of the results drawn from the study.},

The Scopus database is used to retrieve 55?years of OI studies published between 1965 and 2021. The free bibliometric tools Biblioshiny and VOSviewer are used to analyse 1,034 journal papers.
Findings
The result showed that R. Van Dick is the most influential author and the USA is the most involved country in OI research. As per the findings, the Journal of Organizational Behaviour published most of OI research and ?corporate social responsibility? and ?organizational commitment? seem to be the most used keywords alongside OI.
Research limitations/implications
This study will be highly beneficial to OI researchers making their understanding about the construct better. It will also encourage social psychologists to understand the construct utility in workplace social welfare programmes. The research could also help governments and funding bodies to evaluate grant requests. Furthermore, researchers from countries with the lowest proportion of OI studies would be encouraged to spend more time and effort in this area. It will offer insight into international marketing and how individuals and stakeholders perceive and connect with an organization globally.
Originality/value
To the best of the authors' knowledge, this study is one of the important research studies carried out in the domain of OI in the international context. This is also one of the few studies which is spread out across different disciplinary areas including international marketing and management. The success of this paper can open avenues and influence future researchers to study in the OI and related cross-disciplinary areas of international management.},

abstract = {The irregularity of the time interval between observations in and across the stream is a key factor that leads
to a drop in performance when classical machine learning or deep learning models are used for a downstream
task requiring multivariate time series. Indeed, irregular multivariate time series not only increase the rate of
missing values but also lead to data sparsity, which consequently makes the data almost unleverageable and/or
ineffective for models. To tackle this scorching challenge, most of the pioneering approaches apply imputation
or interpolation in their core, which might lead to embedding data with noise. To especially address this
irregular multivariate time series issue, we introduce, in this paper, a new deep neural network model called
ALignment-driven Neural Network. The innovative idea of our model is to transform the irregular multivariate
time series into pseudo-aligned (or pseudo-regular) latent values. The latter are shown as a matrix, where the
coefficients are the latent values of each feature at user-defined reference time points that are evenly spaced.
They are obtained through a duplication process driven by an exponential decay mechanism. The obtained
output is then passed to a Recurrent Neural Network model, which is undoubtedly the must-use model for
regular time series data. To show that our model added value, we looked at the Intensive Care Unit mortality
prediction task. In this unit, the physiological measurements used to make decisions have a problem with
time irregularity. Leveraging the publicly available MIMIC-III, we compare the performance of our model to
that of flagship models. In addition, we also performed extensive ablation studies to highlight the importance
of specific components in our model. Interestingly enough, whenever data is collected 24 and 48 h after a
patient's admission, we outperform our pioneering competitors, i.e., +1.1% and +1.5% for the AUC score, +2.3%
and +2.4% for the AUPRC score and +0.6% and +1.7% for the F1-score.},

This theory is used as a driver for a 2-year action research project conducted at a French management consulting firm during the second attempt of its Business Intelligence (BI) tool baptized ?PMT.? While most MIS methods tend to manage conflicts within the boundaries of an IT project, we emphasize the need for a comprehensive understanding of past IT implementations and their impact on subsequent projects despite the different aims, designs, and functionalities of these IT systems. This research calls for IS researchers and practitioners to adopt a holistic conflict management perspective, considering the IT portfolio and the interplay between various IT systems to ensure successful IT implementation.},

The theoretical framework is integrated with the institutional theory and the resource-based view (RBV). The empirical method is used for collecting data through surveys and further covariance-based structural equation modeling is used to test the hypotheses. Findings indicate that carbon-neutral-based government policies have a stronger influence on tangible resources and human skills than intangible resources related to Industry 4.0 driven smart manufacturing. Second, carbon-neutral policy alignment with the firm's sustainability objectives plays a moderating effect on the relationship between carbon-neutral-based government policies and resources (tangible, intangible resources and human skills) for Industry 4.0 driven smart manufacturing. Lastly, the three resources (tangible, intangible resources and human skills) for Industry 4.0 driven smart manufacturing play a critical role in developing firms' carbon-neutral capability and further enhancing operational performance. Managerial implications include investment in advanced digital technologies, developing a strong mindset among employees and supply chain stakeholders, and designing training programs for enhancing smart manufacturing performance to develop carbon-neutrality capability. This study proposes a hybrid theory in the context of carbon neutrality by integrating institutional theory and RBV. This is the first study that examines the effect of carbon neutrality-based government policies on vital Industry 4.0-driven smart manufacturing resources and the indirect effect on carbon neutrality capability and operational performance.},

?Born global firms? are those organizations which, from their inception and by nature, adopt an essentially global-scale entrepreneurial functional and attitudinal strategy for growth. They seek to gain significant competitive advantage by utilizing their internal resources while leveraging external environment potentialities, to sell their outputs internationally. The aim of this research is to investigate the influence of the external business environment and the dynamic capabilities of born global firms, on their strategic and operational performance, as well as the role of leadership vision on their internationalization performance.
Design/methodology/approach
Initially and resting on extant literature with pertinent foci, including the absorptive capacity and the dynamic capability view theories, a conceptual model is proposed. Subsequently, the model is validated through the partial least square structural equation modeling technique, based on 417 respondents from Indian firms.
Findings
The study concludes that the external business environment and internal dynamic capabilities of born global firms have a significant and positive impact on their strategic, as well as operational performance; with leadership vision playing a significant moderating role to this relationship. The study finally presents the executive implications of the findings and identifies the avenues for further scientific research.
Originality/value
This is a unique study on the topic, both in relation to resources/capabilities versus performance and with regards to the leadership vision's role. It moreover focuses on a primary business force, India, which comprises prime examples of global entrepreneurship. The research constituting a significant contribution to knowledge, as research on how small firms can strategically grow so rapidly and effectively, is still far from conclusive, particularly under the present evolutions that incessantly redefine the contextual business forces upon which strategy is drawn.},

UGC analysis reflects topics related to the NFT initiatives of luxury brands, including their collaborations with artists and celebrities, which are often influenced by the Asian cultures. The perceived value of NFTs in the luxury watch category appears to be primarily functional and utilitarian. In contrast, NFTs in the metaverse cloud and the fashion category are associated with more hedonic, experiential, and symbolic value. Through analyzing transactions on OpenSea, the study also provides evidence that NFTs in the luxury fashion sector are not predominantly viewed as speculative investments.},

This research focuses on efficiently managing the vast amounts of data generated by IoT devices and the continuous data streams they produce, employing an advanced replication and placement strategy for application components across distributed Fog Computing nodes. This approach enables scalable and parallel data processing to adapt to demand fluctuations, prevent over-provisioning, and maintain low response times, making it particularly effective for the dynamic nature of data stream processing in IoT applications.
In this paper, we propose an Optimal IoT Service Replication and Placement (SRP) model, formulated as a constraint satisfaction problem, that considers the diverse requirements of IoT applications and the available infrastructure resources. Our model is designed to be adaptive and extensible, addressing the challenge of workload variability through real-time optimization.
Numerical evaluations confirm the superior performance and scalability of our model over existing methods, while maintaining quality of service constraints. This highlights the potential of our approach to improve efficiency and resource management in Fog Computing environments.},

abstract = {In this conceptual paper, we question the notion of blockchain as trustless, trust-free or trust minimizing technology and we propose a theoretical model that integrates the conceptualization of trust from different disciplines into building a trust layer toward blockchain for end-users. The model delineates trust toward three objects of trust: 1/the platform, 2/peers and service providers, and 3/ the dApp. It also incorporates the process of building trust from initial to knowledge-based trust. Our model and propositions help researchers to examine trust toward blockchain technology in a novel way that includes trusting beliefs toward different objects in the blockchain ecosystem. The model is theoretical and invites an empirical investigation into its predictive validity.},

To address this issue, we propose a framework for the creation of rich Labeled Property Graphs from video surveillance streams. It is based on 1) a Deep Learning pipeline architecture for video data extraction, 2) a graph database module to efficiently structure and store detections, and 3) a querying module to interact with generated graphs, enhancing the automatic analysis of scenes. Its modular architecture enables the feature extraction steps from the videos to be easily maintained, modified or interchanged. Our demonstration scenario shows the process of generating scene graphs from videos of several benchmark datasets. The audience will assist to an end-to-end execution of the pipeline showing the generation process and visualize generated graphs. They will have the opportunity to formulate queries using an interface illustrating several use case scenarios involving person re-identification and abandoned objects matching with their former owners.},

Pour cela, de nombreux indicateurs sont indispensable et requièrent de les comparer aussi bien dans le temps et dans l'espace afin d'évaluer ces progrès. La définition de ces indicateurs nécessite l'exploitation de données existantes notamment les données ouvertes. Toutefois, la diversité des sources de données et des formats pose des défis majeurs en termes de structuration et d'intégration. Malgré l'abondance des données ouvertes, leur exploitation reste limitée, laissant un potentiel inexploité pour orienter les politiques urbaines vers la durabilité. Cet article présente une approche de modélisation dirigée par les données pour les représenter. Nous illustrons l'application de cette méthode aux ODD, et aux événements sportifs ouvrant ainsi de nouvelles perspectives pour établir le rapprochement entre données et calcul d'indicateurs.},

While resilience in HSCs has been widely studied, antifragility has not. 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. NGOs should focus on enhancing trust and governance perception to facilitate digital transformation in HSCs.},

RQ2: How does the CCA capability of B2B firms impact their performance? To validate the theoretical model developed, data is collected through surveys conducted in a developed country (Australia) and a developing country (South Africa). The study holds significance on two fronts: (a) being among the first to examine the influence of institutional pressures on CCA capability development, and (b) uncovering the mediating role of marketing capability in enhancing B2B firm performance through CCA capability. The study's novel contribution lies in identifying pivotal elements for driving exceptional B2B firm performance amidst climate change, while employing institutional theory and the dynamic capability view to elucidate underlying mechanisms.},

En s'appuyant sur une enquête en ligne réalisée auprès de 550 followers de comptes Instagram de différentes marques et sur une expérience basée sur des scénarios impliquant 535 participants, le présent article montre que le caractère éphémère du contenu déclenche le FoMO chez les followers, ce qui influe positivement sur l'engagement et la fatigue envers le compte de la marque. L'engagement (resp. la fatigue) envers le compte de la marque, à son tour, est lié(e) positivement (resp. négativement) à l'attitude envers la marque et à l'attachement à celle-ci. Des analyses plus approfondies révèlent que l'effet total du FoMO chez les followers sur l'attachement à la marque est positif et significatif, tandis que l'effet total du FoMO sur l'attitude envers la marque n'est pas significatif. De plus, le caractère éphémère du contenu a un effet total négatif et significatif sur l'attitude envers la marque. Ces résultats indiquent donc notamment qu'il n'est pas avantageux pour les marques de favoriser le FoMO chez leurs followers Instagram en publiant du contenu éphémère.},

Our investigations focus on the two main questions: measuring the advantage of the insider's additional information and stating a closed form for her hedging strategy. Our approach is based on the results of enlargement of filtration in a discrete-time setting stated by Blanchet-Scalliet and Jeanblanc (in: From probability to finance, Springer, Berlin, 2020) and on a stochastic analysis for marked binomial processes developed in the companion paper (Halconruy in Electron J Probab 27:1-39, 2022).

(Stoch Process Appl 89(1):101-116, 2000; Finance Stoch 7(1):29-46, 2003), Imkeller et al. (1998, 2006) and extends in an insider framework some utility maximization results stated in Delbaen and Schachermayer (The mathematics of arbitrage, Springer, Berlin, 2006) and in Runggaldier et al.

Relying on an online survey with 550 followers of Instagram brand accounts and a scenario-based experiment with 535 participants, this article shows that content ephemerality triggers followers' FoMO, which increases brand account engagement and brand account fatigue. Brand account engagement (fatigue), in turn, positively (negatively) relates to brand attitude and brand attachment. Further analyses reveal that the total effect of followers' FoMO on brand attachment is positive and significant, while the total effect of FoMO on brand attitude is not significant. Moreover, content ephemerality has a negative and significant total effect on brand attitude. A key implication of these findings is that it is not beneficial for brands to foster their Instagram account followers' FoMO by posting ephemeral content.},
