abstract = {Stream Processing Systems (SPSs) are designed to process continuous streams of events, often under highly variable input rates. Although prior work has explored dynamic operator replication, many existing approaches lack generalizability and perform suboptimally across diverse scenarios. In this article, we present MMP-SPS, a predictive self-adaptive framework that extends extends our prior PA-SPS system by introducing a multi-window control loop, support for multiple prediction models, and online model selection via RMSE-based evaluation and multi-armed bandits. Targeting environments with high-volume and fluctuating data streams, such as social media analytics and network traffic monitoring, the framework dynamically selects the most suitable model based on real-time workload characteristics using a reinforcement learning (RL) strategy. To prove the validity of our system, we deployed an implementation of MMP-SPS based on Apache Storm, and we evaluated it on Google Cloud Platform against real-world datasets. Experimental results show substantial improvements in latency, throughput, and resource utilization compared to static and single-model baselines. These findings underscore the potential of multi-model predictive adaptation for scalable and robust stream processing under dynamic conditions.},

abstract = {In this paper, we investigate a steady system used for modelling propagation of reaction fronts in viscous fluids subject to a generalized Arrhenius law. The model consists of the incompressible Navier-Stokes equations for the fluid flow and a set of advection-diffusion equations for the temperature and degree of conversion. The resulting system is strongly coupled and presents many additional nonlinearities as the physical parameters such as the viscosity, diffusion and source terms are assumed to depend on the temperature and/or degree of conversion. Using a fixed-point method we prove the existence and uniqueness of the weak solution for the considered problem. To solve the associated fixed-point problem we consider an iterative scheme and its convergence is also studied in the present study. Here, the proposed scheme uncouples the computation of velocity, temperature and degree of conversion using the fixed-point iteration and we theoretically establish its convergence towards the unique solution of the considered model. Numerical results obtained for two test examples are presented to verify the theoretical analysis and to assess the performance of the proposed algorithm. The obtained computational results for both examples support the theoretical expectations for a good numerical convergence with the developed estimates.},

abstract = {This study develops an integrated forecasting framework that leverages multi-source information fusion to improve predictions of new energy vehicle (NEV) sales in China. The dataset incorporates historical sales records, key influencing factors, and unstructured Baidu Index (BI) data. Our framework first applies complementary ensemble empirical mode decomposition with adaptive noise (CEEMDAN) combined with sample entropy (SE) reconstruction. This procedure decomposes the original sequences into high-, medium-, and low-frequency components, yielding data that are more regular and informative while retaining underlying dynamics. Forecasting is then conducted through a structured combination of methods tailored to each frequency band. High-frequency components are modeled by converting the time series into directed visibility graphs (DVGs) and performing prediction as a link-prediction task on the resulting complex networks, implemented using a particle-swarm-optimized support vector regression (PSO-SVR) model. Medium- and low-frequency components are predicted using backpropagation neural networks (BPNN) and Lasso regression, respectively. Empirical evaluations show that integrating multi-source information, CEEMDAN-SE decomposition, DVG-based modeling, and frequency-specific predictors substantially improves forecasting accuracy compared with benchmark approaches. The findings show the potential evolution of China's NEV market and highlight the drivers of sales dynamics, providing evidence to inform policy formulation and sectoral strategic planning.},

journal = {Journal of Enterprising Communities: people and places of global economy},

abstract = {Purpose - The purpose of this study is to explore the unintended consequences of entrepreneurial orientation

(EO), emphasizing its context-dependent nature, particularly within the unique cultural, regional and

institutional environment of the Gulf Cooperation Council (GCC). This study applies the Paradox Theory to

explore the dualities inherent in EO, aiming to uncover its adverse consequences and identify strategies to

mitigate these effects while enhancing positive outcomes.

Design/methodology/approach - This study uses a qualitative approach, conducting in-depth interviews

with 38 managers from diverse industries across GCC countries.

Findings - This study finds that EO fosters innovation, adaptability and an entrepreneurial mindset, enabling

organizations to maintain a competitive edge. However, EO's core dimensions present paradoxes that create

organizational tensions: Innovativeness vs Stability, Risk-taking vs Safety, Proactiveness vs Decision

Paralysis, Competitive Aggressiveness vs Internal Harmony and Autonomy vs Alignment. These dualities

reflect the complex interplay between traditional values and modern entrepreneurial aspirations in the GCC,

demonstrating context-specific EO practices and paradoxes.

Practical implications - Organizations must implement a structured, context-aware approach to

mitigate the unintended consequences of EO in the GCC. Effective solutions require strategic

communication, prioritization mechanisms, structured decision-making, balanced risk management and

inclusive leadership pipelines. These efforts must be tailored to the GCC's unique socio-economic and

cultural dynamics.

Social implications - EO in the GCC has significant social implications because of its intersection with

traditional values, centralized governance and the reliance on expatriates. It can challenge hierarchical norms,

strain social cohesion and risk excluding marginalized groups, especially women and expatriates. EO may

reinforce inequalities and lead to burnout without inclusive, culturally sensitive approaches. Balancing

innovation with respect for local customs and employee well-being is essential to ensure socially sustainable

entrepreneurial development in the region.

Originality/value - By extending the Paradox Theory to the entrepreneurial domain, this research provides a

nuanced understanding of EO's paradoxical nature. This study highlights how cultural collectivism,

hierarchical structures and institutional constraints influence the implementation and impact of EO. Focusing

on the GCC context, this study offers valuable insights for organizations operating in similar economic and

cultural environments.},

We conduct a scoping literature review of the nascent research on FRAs to synthesize previous research results. We identify two streams of literature: (1) asset management, which focuses on designing FRAs and improving the functioning of these machine advisors, and (2) behavioural finance, which investigates technology adoption and issues concerning biased advice. Among other topics, future research should address why FRAs do not appeal to less financially literate people, who would likely benefit more than others from using them.},

Our results indicate a negative and significant predictive relationship between connectivity and one-month ahead returns. Stocks in the lowest connectivity quintile earn 1.2% - 1.8% monthly return premiums. We further identify an economic mechanism as to why investors demand a premium for holding stocks with sparse broker networks through intraday panel regressions. Our results suggest that broker connectivity is associated with lower adverse selection risks, even for order-driven markets where intermediaries are assumed to be passive agents.},

abstract = {Purpose: This article investigates the business case for Diversity, Equity, and Inclusion (DEI) within the context of Operations and Supply Chain Management (OSCM), a topic that has been the focus of intense debate in academic and practitioner circles, and has become strongly associated with conflicting ideological perspectives. It combines an extensive literature review on DEI and potential outcomes, including the other contributions in the special issue ?On Sustainable Operations and Supply Chain Management: What about Diversity, Equity, and Inclusion??, with empirical analyses, both quantitative and qualitative, to examine the potential outcomes of DEI initiatives.



Design/methodology/approach: In the empirical analysis, a mixed-methods of explanatory sequential design is used. First, the association between OSCM employees' perceptions of workplace DEI and firm-level performance is examined using matched data from Glassdoor employee-reviews of DEI in Fortune 500 companies and Refinitiv Workspace. Then, a qualitative follow-up analysis is undertaken based on 10 interviews with experienced DEI-leaders and OSCM practitioners.



Findings: DEI research in OSCM is still in its early stages and extant knowledge is predominantly based on case studies. Evidence on the relationship between firm-level DEI and performance is mixed and may reflect the context as well as the available information. While there are arguments for a positive association, our quantitative analysis challenges this expectation. Our interviews highlight potential positive outcomes such as enhanced employee engagement and job satisfaction that could translate into performance, but also suggest negative effects when DEI initiatives alienate core groups, are performative rather than substantive, or incur significant short-term costs. Overall, further academic research is needed to address the rhetorics and realities of DEI, understand unfulfilled expectations, identify moderating and mediating factors, and thus potentially resolve inconsistencies in findings.



Originality/value: This introductory article underscores that the DEI debate is far from settled and offers a future research agenda based on an assessment of the current state of DEI scholarship within OSCM, empirical analyses and a review of the seven papers selected for this special issue.},

The key novelty of this model is its ability to derive both the conservation of total energy in the system and an explicit expression

case in which the mass ratio between gas and dust, as well as the Mach and Knudsen numbers, tend to zero.},

Employing a kinetic theory framework, we model the dynamics of the analysts' opinions, by taking both the mutual influences shaping price consensus and the dynamics of the actual S&P 500 index level into account. The model is calibrated on a training subset of data and tested on an independent set to assess its predictive power.

condition on a portion of the boundary leading to energy production.

Additionally, the right-hand side in the TKE equation contains a term ?(k)|?u|2 that is only integrable. The proof of the existence of a weak solution is obtained by regularization of the original problem, relaxing

the terms that are not sufficiently regular. Additionally, due to the nonhomogeneous Dirichlet boundary condition on a portion of the boundary for the energy variable k, we introduce a change of variable for k using the lifting of its value on the boundary of the domain. This implies a new variational formulation with regularization of terms arising from this lifting.},

Specifically, clan and market cultures affect SC readiness, whereas SC responsiveness is influenced by hierarchy as well as clan and market cultures. The moderating role of disruption severity was not found to be significant. However, the MGA revealed that organisations under low severity disruption had a bigger effect of OC on their SC responsiveness.

abstract = {This study investigates the factors influencing older consumers' word of mouth and intention to use meal planner applications,

given that 57% of Malaysians aged 60 and above are active Internet users. The current study utilized an extended technology

acceptance model and the stimulus organism response framework to examine the cognitive-affective dichotomy of usage influence. The respondents were initially selected through purposive sampling and further screened using filter questions to ensure

alignment with the study objectives, resulting in data collected from 392 elderly individuals across various demographic regions of

Malaysia. The analysis was conducted using the Statistical Package for Social Sciences (SPSS) and SmartPLS. The results indicated

that cognitive factors (subjective norm, facilitating conditions, and app characteristics) positively impacted the affective components (perceived usefulness and perceived ease of use), which, in turn, enhanced consumers' attitudes toward using these applications. Furthermore, openness to change and gender were observed to moderate the relationship between affective and

conative responses (word of mouth and behavioral intention). The study provides new insights into the aging population on

food-related mobile applications to governments, food service-based organizations, restaurants, and app designers. Thus,

focus can be on improving app characteristics and facilitating conditions to enhance perceived usefulness and ease of use

while also considering how gender and openness to change may influence consumers' attitudes and behaviors.},

In many applications, this class of fluid flows is challenging to numerically solve using the conventional monolithic methods. The proposed approach belongs to a family of viscosity-splitting methods and it separates the convection term from the incompressibility

constraint into two steps using the second-order implicit backward differentiation formula for the time integration. To ensure the stability of this method, we introduce a numerical scheme based on the scalar auxiliary

variable approach an efficient pressure incrementation is introduced using the scalar auxiliary variable approach. Unlike most projection methods for solving incompressible Navier-Stokes equations, the proposed method is free of any numerical inconsistencies generated by the treatment of boundary conditions in the pressure solution. A rigorous stability analysis is also carried out in this study and the proposed method is demonstrated to be consistent and stable with no restrictions on the time step. Numerical results are presented for three flow problems to validate the second-order convergence rates and to illustrate the performance of the proposed time-splitting scheme for unsteady

non-Newtonian incompressible fluids.},

The conventional transportation system reliant on fossil fuels has adversely affected human lives and the surrounding environment via carbon emissions; in this sense, the adoption of ECs is considered the optimal approach for mitigating transportation emissions. Despite the government initiatives for sustainable mobility, there is a vast disparity between the adoption of electric two and four-wheeler passenger vehicles in several Asian countries. Considering the above, our study intends to assess the psychographic orientation of potential car buyers in India by utilising the hybrid SEM-ANN approach. Our study draws insights from 611 heterogeneous survey responses collected from potential car buyers in India. The novelty lies in developing a conceptual model to explicitly assess different dimensions of EC adoption intentions integrating psychological and technology acceptance theories (TPB, UTAUT, DOI). The empirical research outcomes showed a significant positive influence of performance expectancy, hedonic motivation and attitude on consumers' behavioral intention to adopt EC, followed by trialability, societal influence, image, and effort expectancy, in addition to a negative impact of perceived risk. The study offers actionable insights encompassing theoretical, methodological, managerial and policy implications for promoting sustainable transportation in several markets. A synergistic endeavour of government and business would help engage prospective consumers and create an ecosystem conducive to ECs.},

Technology has changed the way healthcare services are rendered to patients. The present study aims to investigate the factors affecting intentions of Indian patients to switch to healthcare robots.

Design/methodology/approach



Using push-pull-mooring theory, this study evaluates the impact of push, pull and mooring factors on switching patients' intentions to use healthcare robots. To test the relationships, data were collected from 447 patients residing in the Delhi NCR region of India, and responses were empirically examined using Smart-PLS 3.0.

Findings



The present study revealed both the significant and insignificant impacts of factors affecting patients' switching intentions to healthcare robots. Eventually, the study contributes a validated model on switching intentions of patients from traditional healthcare facilities to healthcare robots.

Research limitations/implications



As the present study evaluates the impact of push, pull and mooring factors affecting switching intentions of patients to healthcare robots, therefore, it will specifically help in understanding intentions of patients to switch to healthcare robots. However, this study is cross-sectional in nature and data is collected from Delhi NCR region of India which may limit its generalizability.

Originality/value



This study examines the impact of factors affecting intentions to switch to healthcare robots considering emerging economies which is hardly considered in the past.},

This paper systematically investigates risk spillovers in global staple food markets and explores the key determinants of these spillover effects, combining innovative decomposition-reconstruction techniques, risk connectedness analysis, and random forest models. The findings reveal that short-term components exhibit the highest volatility, with futures components generally more volatile than spot components. Further analysis identifies two main risk transmission patterns, namely, cross-grain and cross-timescale transmission, and clarifies the distinct roles of each component in various net risk spillover networks. Furthermore, price drivers, external uncertainties, and core supply-demand indicators significantly influence these spillover effects, with the heterogeneous importance of varying factors in explaining different risk spillovers. This study provides valuable information on the risk dynamics of staple food markets, offers evidence-based guidance to policymakers and market participants to improve risk warning and mitigation efforts, and supports the stabilization of international food markets and the protection of global food security.},

regulates both morphogens. In this paper, we investigate the emergence of Turing patterns in the synthetic Nodal-Lefty system.

First, we prove the existence of a global solution and derive conditions for Turing instability through linear stability analysis.

Subsequently, we examine the behavior of the system near the bifurcation threshold, employing weakly nonlinear analysis, and

using multiple time scales, we derive the amplitude equations for supercritical and subcritical cases. The results demonstrate the

ability of the system to support various patterns, with the subcritical Turing instability playing a crucial role in the formation of

Through a qualitative analysis of interviews with 22 supply chain (SC), operations, logistics, and procurement managers, the research identifies key paradoxes that emerge when pursuing social goals alongside circular and digital transformations. The study finds that pursuing CDSCs' goals alongside social sustainability objectives creates paradoxical tensions, such as conflicts between efficiency and fair labor practices, data privacy concerns, and the potential for power concentration within digital platforms. These tensions highlight the complexities of balancing competing objectives within CDSC operations. Moreover, the different managerial perspectives, such as SC, operational, logistics, and procurement, may prioritize different aspects of sustainability, leading to potential tensions. These tensions were categorized into four paradoxes: the paradox of progress, the paradox of efficiency, the paradox of control, and the paradox of governance. To manage these paradoxes, the findings highlight the importance of dynamic management, stakeholder engagement, transparency, innovation, and continuous learning. This should also be supported by holistic integration, which involves a unified, comprehensive approach to managing paradoxes in CDSCs, transitioning from separate functional strategies to a cohesive solution. This study contributes to understanding the complexities of social sustainability in CDSCs. It offers insights for practitioners and policymakers seeking to promote more responsible and sustainable SC practices.},

limiting process as the thickness ? of a thin cylinder of R3 goes to 0, and when the polarization

thin-limit process in both cases induces a change of the Lamé coefficients in the displacement

equation, the coupling coefficient between the displacement and polarization equations, the

double wells potential of the polarization together to a new contribution in the equation of the

The interactions between the reaction properties and the fluid dynamics yield a complex and nonlinear model of Navier-Stokes equations for the flow with a strong coupling with two reaction-advection diffusion equations for the temperature and the

degree of conversion. To alleviate difficulties related to the numerical approximation of suchsystems, we propose a fractional-step method to split the problem into several substeps, and based on a viscosity-splitting approach that separates the convective terms from the diffusion

terms during the time integration. A first-order scheme is employed for the time integration of each substep of the proposed fractional-step method. The proposed method also preserves the full original boundary conditions for the velocity which eliminates any potential inconsistencies

on the pressure, and it allows for nonhomogeneous Dirichlet and Neumann boundary conditions

for the temperature and degree of conversion that are physically more appealing. In the present work, we perform an error analysis and provide error estimates for all involved solutions in their relevant norms. A rigorous stability analysis is also carried out in this study and the

proposed method is demonstrated to be consistent and stable with no restrictions on the time step. Numerical results obtained for a problem with known analytical solutions are presented to verify the theoretical analysis and to assess the performance of the proposed method. The method is also implemented for solving a two-dimensional flame-like propagation problem in

viscous fluids. The obtained computational results for both examples support the theoretical expectations for a stable and accurate numerical solver for reactive fluids with Arrhenius activation energy.},

abstract = {Purpose - The purpose of the research is to investigate customer shopping behaviour for Italian market, extra

virgin olive oil (EVOO) using the quick response (QR) code. The study uses means-end chain (MEC) theory to

explore the connections between product attributes, personal values and consumer preferences.

Design/methodology/approach - The theory of means-end chain helps to uncover the underlying reasons why

consumers choose specific products by examining the links between tangibles. There is a conceptual model

developed with the help of MEC. The conceptual framework comprises product information and marketing

communication, which constitute the sensory and non-sensory aspects of consumption behaviour, and it is

empirically tested by CB-SEM technique. QR code usefulness and loyalty are treated as mediators to evaluate

shopping behaviour to purchase EVOO.

Findings - The study has used MEC theory and has extended this theory. This study found that there is a

profound impact of technology (QR code) on the buying behaviour of EVOO for the Italian customers. This

study has also found that product information and product communication play a critical role towards shopping

behaviour of Italian consumers regarding EVOO related products.

Research limitations/implications - Innovation and technology adoption, especially the use of QR codes in

understanding product features, has been an attractive area for research exploration. This could include details

about the product's origin, production methods and nutritional information. Such technology and innovation can change the business process management landscape of food-product distribution process. Not many studies are

available which examine customers' interest and shopping behaviour using QR codes, especially in the context

of EVOO. Thus, this research study has a profound impact on the Italian and other European market.

Originality/value - In the Italian market, EVOO is more than just a product, it is a symbol of tradition, quality

and cultural heritage. EVOO is not just a condiment, it is an essential ingredient that contributes to the overall

flavour of dishes. This study explores the usage of QR code for EVOO related products. This is a unique study as

there are a very few research studies available in this area of business process management and technology usage

related to EVOO products. Moreover, this research study adds values to the body of literature of business process

management, technology usage, innovation and food technology. Thus, this study is unique and adds value to the

existing literature.},

abstract = {Purpose

The dynamic capabilities (DCs) of family firms help to respond to dynamic business environments. Presently, few studies have examined how DCs of family firms could achieve SDGs, especially in the context of economic, social and environmental performance. As such, the present research tries to investigate how DCs of family firms could help to achieve better SDG performance with the mediating role of the firms' sustainable performance.



Design/methodology/approach

Sustainable development goals (SDGs) are designed to achieve a more sustainable and better future for everyone on the planet. Different types of firms are expected to initiate efforts to contribute to these SDGs. Family businesses are key actors in this regard. With the dynamic capability view (DCV) as well as with the knowledge of stakeholder theory as well as with the support of extant literature, a model was prepared that was tested by CB-SEM technique to analyze the responses of 317 respondents.



Findings

This research found that the DCs of these businesses have a significant impact on their SDG performance. The study highlights that family firms are lagging in their reconfiguring capabilities regarding environmental and social performance, so it is a challenging task for family firms to improve on this aspect.



Research limitations/implications

This study deals with cross-sectional data. Therefore, its findings may not be generalizable. Additionally, this study does not address rival or alternative models, which could be seen as a limitation. Furthermore, because the analysis is based on feedback collected from a single geographic region, they may not be universally applicable to other areas.



Originality/value

This study has contributed to the prevailing body of knowledge on family business, sustainable development, firm performance, as well as dynamic resources. The highlights of this study can be used by the entrepreneurs, policymakers, as well as future researchers to further extend this study. Further, this study is also unique as it establishes the importance of the sustainable performance of family businesses with dynamic resources and could also be related to disruptive innovation for family businesses to achieve sustainable performance and to meet the sustainable development goals.},

abstract = {After a brief introduction on present day simulation and modeling of burning plas-

mas in magnetically confined devices, the results of a non-linear benchmark are pre-

sented, undertaken among several state-of-the-art codes available to study the self-

consistent interaction of an Energetic Particle (EP) population with shear Alfvén

waves: HYMAGYC, MEGA, ORB5 and XTOR-K. The first two codes, HYMAGYC

and MEGA, are hybrid codes: HYMAGYC is a MHD-Gyrokinetic code (the bulk

plasma is represented by MHD equations, while the EP species is treated using

the gyrokinetic formalism), while MEGA is an MHD-Drift-Kinetic code (the bulk

plasma is represented by MHD equations, while the EP species is treated using the

drift-kinetic formalism, with the possibility of an ad-hoc gyroaveraging); ORB5

is a global electromagnetic gyrokinetic code (both bulk and EP species are treated

using the gyrokinetic formalism); XTOR-K is a non-linear kinetic-MHD code (the

bulk plasma is described by a set of non-linear resistive two-fluid MHD equations,

extended to include kinetic effects of multiple ion species with a fully kinetic PIC

module). The equilibrium of the so-called NLED-AUG reference case, in its version

with peaked off-axis EP density profile, has been used, while considering a |n| = 1

perturbation. This non-linear benchmark is the natural continuation of the linear

benchmark already considered in the recent past, and represent a first-ever code

comparison in the deep non-linear stage. In the present study fluid non-linearities

are omitted, and the focus will be on comparing wave-particle interactions effects

across codes. Characteristics of the non-linear saturation of the mode, self-consist-

ent modification to the EP density profile and other features are compared among

the considered codes. This brief review presents the state of the art of gyrokinetic

and hybrid MHD-kinetic codes emerging as tools for studying reactor-relevant burn-

ing plasmas in realistic conditions.},

abstract = {This study examines the influence of gender on collaborative and innovative mindsets in

upstream supply chain management (SCM), also considered as supply management. Given

the critical role of these mindsets in addressing today's supply challenges, this research

explores how gender impacts these attributes among supply managers. Using a quantitative

methodology, the study surveyed 250 junior supply managers in training and conducted

a narrow replication with 47 experienced supply managers in the same national context. The

results show significant gender differences in innovative mindset and differences in collaborative

mindset among junior managers only. Supported by replication, the study highlights

gender dimensions in upstream SCM mindsets. It extends discourse on gender in SCM by

linking it to collaboration and innovation. Findings encourage re-evaluating gender biases and

their impact on SCM practices. Practitioners and educators can apply these insights to design

training programmes that address and leverage gender differences, fostering innovative and

collaborative environments.},
