note = {The complexity of database systems has increased alongside the exponential growth of data, necessitating

Information Systems (IS) architects to continuously refine data models and meticulously select storage and

management options that align with requirements. While existing solutions focus on data model transformation,

none offer guidance in selecting the most suitable data model for a given use case. In this context, we propose

DaMoOp, an automated approach for leading data model selection process. DaMoOp starts from a conceptual

model and associated use case comprising queries, settings and infrastructure constraints, to generate relevant

logical data models. A cost model, considering environmental, financial, and temporal factors, facilitates

comparison and selection of the most suitable data model. Our cost model incorporates both data model and

queries costs. Additionally, we suggest a data model selection process that enhances the ability to choose the

optimal data model(s) for a specific use case, while also adapting to rapidly evolving use cases. We provide a

strategic optimization approach designed to identify the most cost-efficient and stable data model as use case

scenarios evolve. Moreover, we offer a simulation tool for the entire process, which enables visualizing the

impact of use case variations on data model costs, thus empowering IS architects to make informed decisions},

We establish the local existence and uniqueness of solutions in the Sobolev space $H^m$, for $m  geq 3$ . We notice that in the incompressible case, the best known existence result requires $m  geq 5$, unless specific thermodynamic conditions are satisfied (their effect is to reduce the high nonlinearity of the model), in which case $m geq 3$ suffices.

Finally, we analyze the linearized system around the constant state and establish the global well-posedness of the solution, as well as its exponential decay in time toward the steady state. In addition, we prove the persistence of regularity for the solution.},

abstract = {A novel second-order time-splitting method is proposed for the numerical solution of non-Newtonian fluid flows governed by the incompressible Navier-Stokes equations with a shear-rate dependent viscosity. 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.},

avenues for testing Turing's predictions. Synthetic mammalian pattern formation has been recently achieved through a reaction-

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

dissipative structures observed experimentally.},

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.},

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

satisfies two different boundary conditions. The first type of boundary conditions leads to an in-

plane model or 2?? 2? configuration while the second one leads to an (in-plane)-(out-of-plane)

model for the displacement and the polarization namely a 2?? 3? configuration. Moreover, the

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

out-of-plane component of the polarization for the 2?? 3? model. The techniques used rely on

a rescaling method that penalizes the out-of-plane variable. Uniform bounds with respect to ?

are established, compactness techniques are employed, and the limits of the penalized terms

are identified.},

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.},

Design/methodology/approach - The study reviews various kinds of literature related to international

marketing, dynamic capabilities, digital transformation, strategic marketing and LES. Following this, a dynamic

capability view is adopted to develop a research model. This research model is later tested using partial least

squares structure equation modeling with data from 385 respondents from different types of organizations.

Findings - The study demonstrates that an organization's DTC significantly enhances its dynamic capabilities

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.},

However, international staple food markets are increasingly exposed to complex risks, including intensified risk contagion and increasing external uncertainties. 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.},

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

critical role in impacting business performance.

Research limitations/implications - Crowdfunding involves investors who have a similar interest in the

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

abstract = {A wide spectrum of natural phenomena and industrial processes involve the propagation of reaction fronts in a viscous fluid medium. Consistent models of this class of problems should account for the competition between the flow dynamics and the reaction properties related to temperature and degree of conversion. In the present study, to resolve these features in reactive flows, we consider the incompressible Navier-Stokes equations with temperature-dependent viscosity for the velocity and pressure coupled with a double system of reaction-advection-diffusion equations for the temperature and the degree of conversion. The reactions in this coupled system are assumed to be generated using the Arrhenius activation energy and cross diffusion coefficients are influenced by both the temperature and degree of conversion. We analyze the solvability of the proposed model and prove existence of the weak solution using a Galerkin approach combined with appropriate compactness arguments. The uniqueness of the solution is also achieved under additional assumptions on the problem data. In the current work, we also introduce a time-marching scheme for the numerical approximation of the continuous problem and prove the unconditional stability with respect to the time step. Numerical results are presented for a problem with exact solutions to verify the theoretical analysis and to assess the performance of the numerical method. The coupled system is also employed to solve a two-dimensional flame-like propagation problem in viscous fluids. The computational results obtained for both examples support the theoretical expectations for a stable and accurate numerical solver for reactive fluids with cross diffusion and Arrhenius activation energy.},

Model Averaging-based estimation technique to fit alternative growth theories to 1960-2009 data on a

BC sample of 23 coastal countries and a worldwide (WW) sample of 83 countries. In addition to

having high mangrove blue carbon climate change mitigation potential, a representative country from

the BC sample possesses features commonly associated with developing countries. Moreover, such a

country's natural capital per capita has decreased by more than 50% during the half-century span of

our data and its dependence on natural capital is almost twice as high as that of its WW counterpart.

We find that the neoclassical theory, through income and investment in physical capital, demography,

macroeconomic policy, and natural capital theories perform well in explaining growth in BC

countries. In contrast, investment in physical capital and proxies for the macroeconomic policy and

natural capital theories are found not to be good predictors of growth when using the WW sample of

countries. These results put the finger on the critical problem of existing and potential anthropogenic

pressure that coastal areas with BC are and can be subject to due to land conversion for agriculture,

aquaculture, farming and other run-offs, marine resources exploitation, uncontrolled sewage, marine

resources direct exploitation, and coastal constructions and public works related to natural capital

exports. This admittedly grim picture of the coasts draws attention to at least two policy questions,

namely, whether central governments ought to give local policy makers and communities incentives to

promote nature-based solutions to climate change mitigation and the extent to which international

financial institutions should provide financial support for such initiatives in developing countries.

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.},

One important application is the study of the formation of turbulence past buildings, with the goal of determining the no-fly zones for drones in smart cities. In this paper, we assess the Unsteady Reynolds Averaged Navier-Stokes (URANS) model, commonly used for simulating urban wind dynamics in small portions of a city. We compare the results with those of the hybrid Large-Eddy-Simulation (URANS-LES) model, more physically comprehensive, but more numerically demanding. By analyzing the aerodynamic loads on models of drones with fixed positions close to buildings, we evaluate the implications of both models for drone flight safety. In this paper, the results demonstrate that URANS significantly underestimates these loads compared to URANS-LES approach, with discrepancies reaching a factor up to three.  This highlights the need for correction strategies when relying on URANS for drone safety assessments in urban environments.},

A family firm's behavior is embedded in an institutional context, and it is important to understand how multiple institutional logic shapes a

family firm's values and ethical behavior. While scholars agree on the central significance of family values and religion in shaping family firms' values and ethical behavior, a definitive consensus on the influence of family values and religion in confronting ethical challenges and shaping ethical behavior has yet to be reached. We lack a theory explaining how family,

family business, and religion shape a family firm's ethical conduct. We conducted a qualitative study to investigate the role

of family values and religion in shaping a family firm's ethical conduct. The results reveal four themes, namely (a) ethical

challenges faced by family firms, (b) family values shaping ethical behavior, (c) religion providing a rationale for family firms'

ethical decision-making, and (d) outcomes of ethical decision-making. The principal contribution of our study is clarifying

the role of multiple institutional logics in the form of religion and family in explaining ethical behavior. Our findings sugges that the fit between religion, family, and business as an institution guides decision-making, helps family businesses earn a positive reputation in the community by displaying ethical behavior, and develops a positive workplace climate.},

corporate social responsibility (CSR) initiatives of sports firms that are focused on sports education,

community development and sustainable livelihoods and their effects on organizational citizenship behaviors

(OCBs) and sustainable business excellence (SBE).

Design/methodology/approach - A conceptual model is proposed, which is derived from stakeholder theory

and social identity theory, along with related literature. The conceptual model was validated using mediation and

moderation analysis of the survey data from 384 respondents. PLS-SEM was used to assess the measurement

constructs and to examine the structural path relationships hypothesized in the proposed research framework.

Findings - The proposed model supports the hypotheses that harmonious CSR in sports, communities and

livelihoods nurtures greater OCBs, which improves organizational performance and SBE. Furthermore, it was

found that perceived corporate reputation does not moderate the OCB?performance link, whereas fan

engagement moderates the performance-sustainability relationship. The findings extend stakeholder theory

and social identity theory and they provide practical guidance on optimizing harmonious CSR strategies.

Research limitations/implications - This study has focused on a specific context, limiting the

generalizability of the findings. This provides opportunities for future researchers to explore the applicability

of the findings across different countries, enriching the outcomes with more generalizability. This study

depends on cross-sectional data inviting defects of causality and endogeneity.

Practical implications - There are several practical implications of this study. Sports organizations should

engage their stakeholders in CSR activities that will lead to improvement in business performance. Moreover,

sports organizations could improve their corporate reputation through investing in harmonious CSR activities

for the well-being of society.

Originality/value - To the best of the authors' knowledge, this is the first study to be conducted on how

harmonious CSR activities could achieve better sustainable business outcomes for sports organizations by

fostering a culture of social responsibility and thereby improving overall organizational performance. This was

a gap in previous research, which has been duly addressed in this study},

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

We start by showing the intermediate time well-posedness in the case of general topography (i.e. the amplitude of the bottom graph ?=O(1)). The novelty resides in the functional setting, Hs(R), s>12. Then we show our main result establishing that the global existence result obtained in [14] in the flat bottom case is still valid for the Boussinesq-Peregrine system under the hypothesis of small amplitude bottom variation (i.e. ?=O(?)). More precisely we prove that this system is unconditionally globally well-posed in the Sobolev spaces of type Hs(R), s>12. Finally, we show the existence of a weak global solution in the Schonbek sense [18], i.e. existence of low regularity entropic solutions of the small bottom amplitude BoussinesqPelegrine equations emanating from u0?H1and ?0in an Orlicz class as weak limits of regular solutions.

Mitigating NLOS receptions for GNSS is essential, especially for safety-critical and reliability-critical location-based applications. Traditional physical error channel propagation modeling encountered bottlenecks since the NLOS and multipath errors cannot be modeled accurately in complex urban environments. Data-driven methods show significant potential for effectively classifying GNSS Line-of-sight (LOS) and NLOS. This paper proposes the CarNet - a generative Convolutional Neural Network (CNN)-based GNSS LOS/NLOS classifier by transforming multivariate time-series data into images. CarNet comprises two modules: an image generator and an image classifier. The image generator enriches and augments the original 1-dimension feature vector into 2-dimension feature maps and the image classifier uses an inception-based CNN to realize multi-scale feature extraction and classification. The proposed architecture is trained and tested on more than 6 h of real vehicle data collected in different challenging environments (about 1.6 million samples). A thorough benchmark is conducted, comparing CarNet against the existing mainstream Artificial Intelligence (AI) methods. The results with cross-validation on unseen data indicate that CarNet achieves the highest accuracy, i.e., 81.47% while maintaining the optimal balance between precision for both classes: 83.3% for LOS and 70.99% for NLOS. Finally, positioning accuracy is assessed using a reweighting strategy based on the LOS/NLOS information predicted by CarNet. The assessment of total datasets shows that CarNet weighting can achieve the best accuracy compared to the traditional weighting schemes based on signal-to-noise ratio or satellite elevation. CarNet shows strong potential for embedding into GNSS receivers to enhance positioning accuracy in complex urban environments, benefiting a wide range of location-based applications such as autonomous driving, emergency response, and urban logistics.},

understanding of NoLo wines consumption as a social behaviour among Italian millennials.

Design/methodology/approach - The research design comprises symmetrical and asymmetrical approach.

The study employs Cluster and fsQCA to understand the granularities of NoLo wine consumption.

Findings - The present study reveals that young adults are willingness to pay (WTP) more for NoLo wine in

exchange of improved health benefits as a reward. The contrarian observation of relatively consumers with low

average income exhibiting the high willingness to pay more for NoLo wine.

Research limitations/implications - The sample islimitedto Italyand skewed in terms ofNoLowine consumption.

The participants were aware of NoLo wine but did not consume it in the past year. The study identified the

paradoxical stance of low average family income group exhibiting more willingness-to-pay for de-alcoholised wine.

that promote well-being and reduce health risks associated with excessive alcohol consumption. Secondly,

mindfulness practices have gained popularity among young adults for altering self-perception, leading to a

preference for beverages that align with mindful consumption and stress reduction. NoLo wine offers a suitable

alternative, providing a similar sensory experience without the intoxicating effects of alcohol.

Social implications - Habit theory, pioneered by James (1890), posits that habits are formed through a three-stage

process: cue,routine and reward.In the context of NoLo wine consumption, cues can include social gatherings, dining

occasions orstressrelieftriggers. The routine involvesthe act of consuming NoLo wine, while the reward stemsfrom

the perceived benefits of this wine, such as reduced alcohol intake, improved health and social acceptance. The

prevalence of NoLo wine consumption among Italian young adults can be attributed to a confluence ofsocialfactors.

Originality/value - The paper attempts to evaluate the contrarian case using fsQCA and the conceptual

configuration of necessary conditions, viz. self-perception, social norms and health-consciousness.},

abstract = {In the realm of information fusion, clustering stands out as a common subject and is extensively applied across various fields. Evidential clustering, an increasingly popular method in the soft clustering family, derives its strength from the theory of belief functions, which enables it to effectively characterize the uncertainty and imprecision of data distributions. This survey provides a comprehensive overview of evidential clustering, detailing its theoretical foundations, methodologies, and applications. Specifically, we start by briefly recalling the theory of belief functions with its transformations into other uncertainty reasoning theories. Then, we introduce the concepts of soft data, partitions, and methods with an emphasis on data and partitioning within the theory of belief functions. Subsequently, we summarize the advancements and quantitative evaluations of existing evidential clustering methods and provide a roadmap to help in selecting an appropriate method based on specific application needs. Finally, we identify the major challenges faced in the development and application of evidential clustering, pointing out promising avenues for future research, including theoretical limitations, applicable datasets, and application domains. The survey offers a structured understanding of existing evidential clustering methods, highlighting their theoretical underpinnings, practical implementations, and future research directions. It serves as a valuable resource for researchers seeking to deepen their understanding of evidential clustering.},

Unlike most of the projection methods for solving incompressible Navier-Stokes equations, the proposed method is free from any numerical inconsistencies generated by the treatment

of boundary conditions on the pressure solution. Two pressure-correction strategies including the scalar auxiliary variable approach are proposed to enhance the accuracy of the method.

A rigorous stability analysis is also carried out in this study for the considered strategies.

Numerical results are presented for three benchmark problems to validate the unconditional stability and to demonstrate the performance of the proposed fractional-step method for solving unsteady incompressible viscous flows. The obtained computational results support our

theoretical expectations for an unconditionally stable second-order fractional-step method for the incompressible Navier-Stokes equations.},

Furthermore, the study also tried to uncover the moderating impact of absorptive capacity and economic policy uncertainty on above mentioned relationship. The moderating effect could deaccelerate carbon neutrality and could create hindrance towards circular economy. Hence, absorptive capacity is anticipated to influence how organizations assimilate and apply digital advancements, while economic policy uncertainty is expected to shape the overall landscape within which these transformations occur. The study followed a quantitative design and PLS-SEM analysis. The results show the importance of digital transformation in in order to derive environmental sustainability within supply chains. In this study absorptive capacity found as a significant moderator. The results offer valuable insights for businesses in order to to enhance environmental sustainability. Also, these efforts with digital transformation and effective SCM practices can help a firm to achieve carbon neutrality. This distinct approach promotes more sustainable and resilient green supply chain practices that enables businesses to stay agile and accelerate circular economy practices.},

This study aims to examine how an organization's innovation capability could influence research and development (R&D) performance. It also investigates if industry-academic knowledge transfer has a moderating relationship between organizational innovation capability and exploration and exploitative innovation in improving the R&D performance of the organizations.

Design/methodology/approach



Based on the literature and dynamic capability view, a conceptual model was developed and then validated using the partial least squares-structural equation modeling technique considering 387 responses from academicians and industry personnel.

Findings



The study found that industry-academic knowledge transfer has a significant moderating impact toward improving innovation capability, organizations' R&D performance and exploration innovation. However, it has an insignificant moderating impact on improving innovation capability and exploitative innovation.

Practical implications



Organizational innovation capability is characterized by both exploratory and exploitative innovation. Both types of innovation support the R&D performance of an organization. Also, organizations that closely work with academic institutions could gain significant R&D knowledge from academic expertise. This study provides food for thought for the academic community as well as industry policymakers.

Originality/value



There are significant opportunities for academic institutions to gain practical knowledge from industry which can help them to accelerate their R&D activities. However, transferring knowledge between industry and academia has challenges related to intellectual property, patents and so on. Not much research has been conducted in this area. Thus, the proposed research model is unique and adds to the existing literature.

obey a (focusing) nonlinear Schrödinger equation (NLSE) (E. Poli, Phys. Plasmas, 2021).

This equation predicts susceptibility of GAM packets to the modulational instability (MI).

The necessary conditions for this instability are analysed analytically and numerically

using the NLSE model. The predictions of the NLSE are compared with gyrokinetic

simulations performed with the global particle-in-cell code ORB5, where GAM packets

are created from initial perturbations of the axisymmetric radial electric field E r . An

instability of the GAM packets with respect to modulations is observed both in cases in

which an initial perturbation is imposed and when the instability develops spontaneously.

However, significant differences in the dynamics of the small scales are discerned between

the NLSE and gyrokinetic simulations. These discrepancies are mainly due to the radial

dependence of the strength of the nonlinear term, which we do not retain in the solution

of the NLSE, and to the damping of higher radial spectral components k r . The damping

of the high- k r components, which develop as a consequence of the nonlinearity, can be

understood in terms of Landau damping. The influence of the ion Larmor radius ? i as well

as the perturbation wavevector k pert on this effect is studied. For the parameters considered

here the aforementioned damping mechanism hinders the MI process significantly from

developing to its full extent and is strong enough to stabilize some of the (according to the

undamped NLSE model) unstable wavevectors.},

components of KM in our research: knowledge generation (KG), knowledge transfer (KT), and knowledge acquisition (KA). We

obtained responses from 336 respondents who took part in this study. We used PLS-SEM

to analyze the data. The findings indicate

that innovation plays an essential role in establishing a relationship between KM and OR. Firm age is found as a significant

moderating factor of this relationship. It implies that, to be robust, older enterprises in MSMEs should prioritize both KM and

innovation. This study can serve as a useful resource for MSMEs that wish to learn more about the role of innovation in utilizing

the convection and diffusion terms of both velocity and temperature solutions are uncoupled while a viscosity term is kept in the correction step at all times. 

This fractional-step method maintains the same boundary conditions imposed in the original problem for the corrected velocity solution, and it eliminates all inconsistencies related to boundary conditions for the

treatment of the pressure solution. In addition, the method is unconditionally stable, and it allows the temperature to be transported by a non-divergence-free velocity field. In this case, we introduce a methodology to handle the subtle temperature convection term in the error analysis

and establish full first-order error estimates for the velocity and the temperature solutions and 1?2-order estimates for the pressure solution in their appropriate norms. Three numerical examples are presented to demonstrate the theoretical results and examine the performance of the proposed method for solving unsteady thermal convection in non-Newtonian fluids.

hydrocarbon gases, predominantly methane, which is released in significant quantities during mining operations. Effectively

mitigating methane emissions is imperative. The inclusion of methane forecasting allows for the early identification of potential methane emissions, hence results in significance enhancement in mine safety. The research work is focused on real-time remote monitoring and cloud-based forecasting of methane levels in underground coal mines. An Industrial Internet of Things (IIoT) device is developed for data acquisition in underground coal mines, capturing essential parameters such as methane concentration,

temperature, and humidity. The collected data are utilized to train LSTM based multivariate forecasting model. The trained model is

subsequently deployed in the cloud. The experiment is performed in a mine of Eastern Coalfields Limited, India. After the deployment

of the proposed model, the developed IIoT device transmits real-time data, obtained from the mine, to the cloud. Based on the real

time data, our model conducts methane forecasting and communicates results back to the IIoT device. The device issues immediate

alerts when methane levels surpass predefined thresholds. This ensures enhanced safety in mining operations by providing warnings

for both current and forecasted methane concentrations. The forecasted methane concentrations, along with real-time data, are

accessible through mobile applications and a web-based dashboard. The accuracy of the proposed model is measured by mean

absolute error, mean absolute percentage error and root mean square error, which demonstrate values of 156.95 ppm, 4.23% and

191.53 ppm respectively. A comparative study is performed where our model is evaluated against the multivariate Multilayer

Perceptron (MLP), Vector autoregression (VAR) and Auto-Regressive Integrated Moving Average (ARIMA) models. The comparative

SDGs established by the United Nations provide a comprehensive framework for addressing global issues. To monitor progress towards these goals, we need to develop key performance indicators and integrate and analyze heterogeneous datasets. The definition of these indicators requires the use of existing data and metadata. However, the diversity of data sources and formats raises major issues in terms of structuring and integration. Despite the abundance of open data and metadata, its exploitation remains limited, leaving untapped potential for guiding urban policies towards sustainability. Thus, this paper introduces a novel approach for SDG indicator computation, leveraging the capabilities of Large Language Models (LLMs) and Knowledge Graphs (KGs). We propose a method that combines rule-based filtering with LLM-powered schema mapping to establish semantic correspondences between diverse data sources and SDG indicators, including disaggregation. Our approach integrates these mappings into a KG, which enables indicator computation by querying graph's topology. We evaluate our method through a case study focusing on the SDG Indicator 11.7.1 about accessibility of public open spaces. Our experimental results show significant improvements in accuracy, precision, recall, and F1-score compared to traditional schema mapping techniques.},

We use here numerical experiments performed with a 'particles modes' model based on a double average over the fast cyclotron phase and over the bounce (or transit) phase to show the major role played by energetic particles and shear flows in this scenario. 'Particle modes' are meant here as classes of particles, identified by some adiabatic invariant after a gyro-average procedure, which are associated to the description of some specific linear modes of the plasma. The introduction of energetic circulating ions or shear flows into the system makes a larger number of particle modes being involved in the synchronization process. A global synchronization of the Fourier modes of the turbulent spectrum can be this way achieved. This process allows for a bifurcation towards self-organization, which is associated to the emergence of a staircase-like structure. This is known to be an essential element in the modification of the zonal flow pattern in phase space during the suppression of microturbulence in tokamaks.},
