abstract = {In general, supervisor abuse is directed toward lowperforming subordinates. Similarly, envy is typically felt by professionals in lower ranks toward those in higher positions. By contrast, this study investigates the counterintuitive relationship between the abusive
behavior of envious leaders toward their competent subordinates. Specifically, we argue that supervisors become envious of competent employees when they
are anxious about losing power. Multisource, timelagged data collected from dyads (198 supervisors and 198 subordinates) in Pakistan-based organizations support the proposed hypotheses. The findings show a positive
relationship between perceptions of subordinate competence, supervisors' downward envy, and abusive supervision. In addition, the relationship between
perceived subordinates' competence and supervisors' envy is strong when supervisors' power loss concerns
are high. This study provides useful theoretical and Practical insights for human resource managers dealing with unethical workplace behavior.},

abstract = {We propose a fractional-step method for the numerical solution of unsteady thermal convection in non-Newtonian fluids with temperature-dependent physical parameters. The proposed method is based on a viscosity-splitting approach, and it consists of four uncoupled steps where
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. The computational results obtained for the considered examples confirm the convergence, accuracy, and applicability of the proposed time fractional-step method for unsteady thermal convection in non-Newtonian fluids.},

abstract = {The equilibrium efficient frontier data envelopment analysis (EEFDEA) has been extensively used to evaluate efficiencies of the decision-making units (DMUs) with fixed-sum outputs. This study develops a new EEFDEA approach based on a proportional frontier-shifting strategy. Our approach applies an iterative procedure to find the equilibrium efficient frontier (EEF). Each iteration uses a proportional frontier-shifting model to improve an inefficient DMU to the efficient frontier by increasing its fixed-sum outputs. Meanwhile, the DMUs on the efficient frontier decrease fixed-sum outputs proportionally to ensure the total fixed-sum outputs are unchanged. Our theoretical developments show that the proportional frontier-shifting strategy is feasible and can finally obtain a unique EEF. The new approach allows DMUs to use their preferred input and output weights when determining the EEF. This generates an EEF that better aligns with real-world practices and avoids the need to construct it as a single hyperplane, as required by conventional EEFDEA methods. It also avoids unfair adjustments in fixed-sum outputs among the DMUs and eliminates the problem of peculiar efficiency evaluation results (i.e., some DMUs obtain extremely high, or infinity, efficiencies). Finally, we apply our approach to a case study of Chinese vehicle industry companies to demonstrate its usefulness and compare it with the previous representative approach.},

abstract = {The research proposes a new methodological framework based on dynamic priority to handle different order classes in robotic warehouse systems. Traditional static priority methods in facility logistics may cause low-priority orders to experience excessive delays and fail to ensure fairness. Our dynamic priority approach addresses this fairness issue by adjusting priorities over time to fulfill orders within promised times, ensuring both high-priority orders and long-waiting low-priority orders receive timely attention. We present stochastic models of dynamic priority queueing networks to describe warehouse systems and estimate throughput times. Experiments validate the analytical stochastic models, and experimental results indicate that the dynamic priority model achieves shorter delay times than the static priority model and the FCFS model. We propose design insights based on experimental results and provide an approach to select the optimal robot number. Furthermore, by employing a fairness index, we develop a new decision support tool for determining warehouse configurations with requested performance objectives. Experimental results demonstrate that dynamic priority can ensure fairness across a wider range of scenarios. Additionally, with insufficient pickers, the system performs better with the put wall than without it.},

We apply the autoregressive distributed lags model and fully modified ordinary least squares approach to examine 37 years of historical data and elicit robust findings. Our main results are threefold. First, while an initial rise in the sharing economy does not lead to short-run changes in sustainable development, its impact becomes positive in the long run and advances sustainable development. Second, sustainable development is a long-term process to which technological innovation positively contributes, irrespective of the short or long run. Third, domestic and foreign investors positively contribute to sustainability, while economic growth has an inverted U-shape relation with sustainable development. These findings thus suggest that the sharing economy and innovation help boost real-world development and promote a circular economy.},

For working through pipe bends and junctions, a tensegrity mechanism is introduced into this robot to have a flexible design. An experimental test bench is then developed to understand the working limits of the tensegrity mechanism. In order to work inside a certain diameter range of pipelines, an optimization approach is then followed to determine the size of motors and leg mechanisms for the robot assembly. The static modeling of the robot assembly is then proposed for horizontal orientation where the assembly resembles a series-parallel hybrid manipulator.},

This exploratory research investigates why people create, trade or collect NFTs, what value they derive from them, and how online communities contribute to value co-creation. Over the course of two rounds, we interview 38 participants, most of whom are digital natives. We find that engaging with NFTs is the new form of day trading, reflecting financialization of everyday life. The value of NFTs is mainly speculative and utilitarian, and NFTs themselves are best thought of as derivatives. Value co-creation in NFT project communities is largely focused on gaining superior information about the project. We contribute to the crypto-marketing and web3 literature by advancing a novel model of NFT consumer value that extends Holbrook's (1999) typology and distinguishes both positive and negative aspects of consumer value that have been overlooked in mainstream literature. We shed light on the role of communities in an unusual setting: a nascent, illiquid, speculative, informationally opaque market for digital assets. Our study helps creators and brand managers to develop effective NFT strategies.},

The linear, nonlinear Alfvén modes, and the zonal flow dynamics are investigated, and their respective radial structures and saturation levels are reported. ITG dynamics in the presence of the zonal flows excited by these Alfvén modes are also investigated. The zonal flows forced-driven by Alfvén modes can significantly impact the ITG dynamics. A zonal flow amplitude scan reveals the existence of an inverse relation between the zonal flow amplitude and the ITG growth rate. These results indicate that forced-driven zonal flows can be an important indirect part of turbulence mitigation due to the injection of energetic particles.},

abstract = {Gas emissions from ships are a major environmental concern of the international maritime
community. Market-based measures with incentive have been developed to reduce gas
emissions. One such measure is the differentiation of port dues through the provision of
rebates to environmentally friendly vessels. Existing research reveals several limitations
that hinder their actual impact on emissions, such as low rebate rates, the lack of
transparency of the schemes, and the costs for the port authorities, among other factors. Our
article reveals that differentiated schemes can be improved to elicit changes in the shipping
industry. Based on data from the Port of Tallinn, we develop an illustrative air emission
index to show how transparency in the scheme can be reconciled with environmental
targets. The brackets and rates of the scheme should be determined transparently based
on an ex ante target and on the distribution of the emission index of vessels that call at the
port. From a policy perspective, we highlight how such a transparent process can increase
compliance with the schemes and how surcharges are essential to the provision of attractive
rebates by preserving the financial stability of the port authority.},

Each variable is computed using an iterative procedure, with the pressure step involving a simple L2-projection. We provide a proof of the convergence of the scheme to the continuous problem under smallness assumptions on the data. This theoretical analysis ensures the reliability of our method in approximating the behavior of the stationary second grade fluid model.

It includes sharing a single platform by multiple organizations. These organizations can be rivals competing in the same marketplace. Often, organizations can share their employees, data, and other resources. Although there are multiple benefits in a platform-based sharing economy business model, there are some ethical concerns, too. Limited studies have extensively investigated how adopting a platform-based sharing economy business model could provide both opportunities and challenges impacting the intention of the organizations to adopt this model. From such a perspective, this study aims at an in-depth investigation of employees' perceptions regarding the intention of adopting sharing economy models through which organizations could enjoy various benefits that overcome the risks. With the help of a resource-based view with other theories and the extant literature, a conceptual model has been developed, which later has been validated using the PLS-SEM technique considering 376 responses from different organizations in India. This study has demonstrated how the benefits derived from adopting a platform-based sharing economy business model overcome the risks involved and could motivate organizations to intend to adopt such a business model.},

This study predicts failure causes using AI on multimodal data from industry settings. A classification method applied to aeronautical machining data achieves 98.9% accuracy, and an NLP approach evaluated on semiconductor data reaches 97.8% accuracy.

characterizing resistance to failure. Predicting its value from the solid structure at the atomistic scale remains elusive, even in the simplest situations of brittle fracture. We report here numerical simulations of crack propagation in two-dimensional fuse networks of different periodic geometries, which are electrical analogs of bidimensional brittle crystals under antiplanar loading. Fracture energy is determined from Griffith's analysis of energy balance during crack propagation, and fracture toughness is determined from fits of the displacement fields with Williams' asymptotic solutions. Significant size dependencies are evidenced in small lattices, with fracture energy and fracture toughness both converging algebraically with system size toward well-defined material-constant values in the limit of infinite system size. The convergence speed depends on the loading conditions and is faster when the symmetry of the considered lattice increases. The material
constants at infinity obey Irwin's relation and properly define the material resistance to failure. Their values are approached up to ? 15% using the recent analytical method proposed in Nguyen and Bonamy (Phys
Rev Lett 123:205503, 2019). Nevertheless, the deviation remains finite and does not vanish when the system size goes to infinity. We finally show that this deviation is a consequence of the lattice discreetness and
decreases when the super-singular terms of Williams' solutions (absent in a continuum medium but present here due to lattice discreetness) are taken into account.},

abstract = {To enhance the accuracy of breast cancer diagnosis, current practices rely on biopsies and microscopic examinations. However, this approach is known for being time-consuming, tedious, and costly. While convolutional neural networks (CNNs) have shown promise for their efficiency and high accuracy, training them effectively becomes challenging in real-world learning scenarios such as class imbalance, small-scale datasets, and label noises. Angular margin-based softmax losses, which concentrate on the angle between features and classifiers embedded in cosine similarity at the classification layer, aim to regulate feature representation learning. Nevertheless, the cosine similarity's lack of a heavy tail impedes its ability to compactly regulate intra-class feature distribution, limiting generalization performance. Moreover, these losses are constrained to target classes when margin penalties are applied, which may not always optimize effectiveness. Addressing these hurdles, we introduce an innovative approach termed MF-BAM (Mises-Fisher Similarity-based Boosted Additive Angular Margin Loss), which extends beyond traditional cosine similarity and is anchored in the von Mises-Fisher distribution. MF-BAM not only penalizes the angle between deep features and their corresponding target class weights but also considers angles between deep features and weights associated with non-target classes. Through extensive experimentation on the BreaKHis dataset, MF-BAM achieves outstanding accuracies of 99.92%, 99.96%, 100.00%, and 98.05% for magnification levels of ×40, ×100, ×200, and ×400, respectively. Furthermore, additional experiments conducted on the BACH dataset for breast cancer classification, as well as on the LFW and YTF datasets for face recognition, affirm the generalization capability of our proposed loss function.},

abstract = {The use of electric vehicles is gaining momentum throughout the world. Low-carbon mobility is a core area of
focus for sustainable transportation in smart cities. Policy makers and governments in many countries are
incentivizing the manufacture, sale, and purchase of low carbon-emitting vehicles such as electric vehicles. Not
many studies have focused on the usage of electric vehicles in smart cities from the perspectives of customer
behavior and government incentive. Therefore, the aim of this study is to understand how the moderator government
incentives influence potential customers' intention to purchase electric vehicles for smart mobility in
smart cities. With the help of the theory of planned behavior and various literature, a theoretical model has been
developed which is later validated using CB-SEM technique considering responses from 415 potential customers
of electric vehicles. This study has demonstrated that subjective norms and personal norms supported by users'
attitude and behavioral control to use EVs could impact on the purchase intention of electric vehicles with active
support of the government incentives. This study has proposed a pragmatic framework helpful for the policymakers
to motivate the potential purchasers of the smart cities to purchase EVs.},

Developing multilevel resilience enables organizations to better anticipate conflicts and respond to environmental disruptions. Through correlation and regression analysis based on 148 respondents from companies in Russia, we build the relationship between adaptive leadership and three levels of resilience, unpacking the new role of leadership in shaping managerial responses to contextual change. The results suggest that adaptive leadership can positively influence all three levels of resilience, with adaptive leadership having the most significant impact on team resilience, then organizational resilience, leaving employee resilience behind. Such findings contribute to a deeper understanding of how exactly managerial mechanisms should be redesigned to overcome disruptions and develop leadership capabilities.},

The task is the recognition of 7 motion classes given their spatial coordinates in a frame-by-frame motion. The skeletal data has been captured using a Vicon system and pre-processed into a coordinate system using Blender and Vicon Shogun Post. We created a small, novel dataset with a high variety of durations in frames.

Using a Bayesian Structural VAR model, we evaluate the impact of interest rate shocks (as a price rule) and shocks to the monetary aggregate (M2) (as a quantity rule) on those commodity prices. Our main findings are fourfold. First, a positive interest rate shock has a negative and persistent effect on commodity prices, with beverages and metals commodity prices falling the most in response to such shock. Second, a positive shock to the growth rate of M2 has a strong impact on the prices of non-fuel commodities, agricultural raw materials, and metals. Still, the highly volatile food and fuel (energy) commodity prices are less affected. Third, while both the growth rate of M2 and the interest rate seem relevant macroeconomic stabilizers, the quantity instrument appears more effective than the price instrument in explaining commodity prices. Finally, while interest rate hikes are linked with a persistent rise in world uncertainty, monetary expansions lead to a long-lived fall in this variable. All in all, our study provides new evidence about the impact of China's monetary policy on global commodity prices using a rich dataset and an econometric setup that accounts for uncertainty.},

abstract = {In recent years, significant development has been made in efficiency evaluation for Decision-Making Units (DMUs) with fixed-sum outputs. The Generalized Equilibrium Efficient Frontier Data Envelopment Analysis (GEEFDEA) approach introduced by Yang et al. (2015) is one of the most representative methods. In the GEEFDEA approach, all DMUs are adjusted to become efficient under the same set of weights, indicating that the Equilibrium Efficient Frontier (EEF) constructed consists of only one hyperplane. However, in practical scenarios under the Variable Return to Scale (VRS) assumption, the production frontier always consists of multiple hyperplanes, presenting a more complex shape. To fill this research gap, we propose an improved Equilibrium Efficient Frontier Data Envelopment Analysis approach. Our approach allows DMUs to have different weights for inputs, variable-sum outputs, and fixed-sum outputs, resulting in an EEF with multiple hyperplanes. It is noted that our new approach uses a non-linear model to obtain the EEF. We show that the model can be linearized in the case of a single fixed-sum output. In situations involving multiple fixed-sum outputs, we propose an algorithm based on the Expectation Maximization (EM) mechanism to solve the model to obtain an EEF. Finally, we illustrate the advantages of our new approach through a numerical example and a case study in the global motor vehicle industry.},

Based on a sample of French-listed firms from the period 2007 to 2016, the authors use GLS regression models on panel data estimated with robust standard errors, clustered at the firm level. The results show that firms' CSR performance is negatively associated with stock price crash risk. These findings suggest that socially responsible firms are less likely to hide bad news and poor performance to comply with stakeholders' ethical expectations, which reduces the stock price crash risk. Furthermore, we find that CSR indirectly decreases the stock price crash risk by enhancing accounting conservatism. This result suggests that accounting conservatism is a channel through which CSR decreases stock price crash risk. Our results provide practical implications for policymakers about the necessity to increase CSR activities as a good corporate governance device.},

abstract = {Medical image segmentation often faces challenges related to overfitting, primarily due to the limited and complex training samples. This challenge often prompts the use of self-supervised learning and data augmentation. However, self-supervised learning requires well-defined hand-crafted tasks and multiple training stages. On the other hand, basic image augmentation techniques like cropping, rotation, and flipping, effective for natural scene images, have limited efficacy for medical images due to their isotropic nature.
While regional dropout regularization data augmentation methods have proven effective in image recognition tasks, their application in image segmentation is not as extensively studied. Additionally, existing augmentation methods often operate on square regions, leading to the loss of crucial contour information. This is particularly problematic for medical image segmentation tasks dealing with regions of interest characterized by intricate shapes. In this work, we introduce LCAMix, a novel data augmentation approach designed for medical image segmentation. LCAMix operates by blending two images and their segmentation masks based on their superpixels, incorporating a local-and-contour-aware strategy. The training process on augmented images adopts two auxiliary pretext tasks: firstly, classifying local superpixels in augmented images using an adaptive focal margin, leveraging segmentation ground truth masks as prior knowledge; secondly, reconstructing the two source images using mixed superpixels as mutual masks, emphasizing spatial sensitivity. Our method stands out as a simple, one-stage, model-agnostic, and plug-and-play data augmentation solution applicable to various segmentation tasks. Notably, it requires no external data or additional models. Extensive experiments validate its superior performance across diverse medical segmentation datasets and tasks.

abstract = {Organizations are increasingly expecting individuals to engage in task proactivity, that is, to find better ways of doing their job. While prior research has demonstrated the benefits of task proactivity, little is known about its cognitive costs. To investigate this issue, we build theory on how task proactivity affects end-of-day cognitive performance. We propose that task proactivity involves deviating from established ways of working and engaging in cognitively demanding activities requiring high levels of mental effort, which manifest as an erosion of end-of-day cognitive performance. In two daily diary studies, we found that individuals engaging in task proactivity experience lower end-of-day cognitive performance (Study 1 over five consecutive workdays: n = 163, k = 701; Study 2 with multiple daily assessments over seven consecutive workdays: n = 93, k = 471), even when controlling for task performance (Study 1) and beginning-of-day cognitive performance (Study 2). In two experiments, we then show that simulating task proactivity results in greater mental effort and lower routineness but not in greater ego depletion (Study 3: N = 318 and Study 4: N = 319) or increased self-control demands, -effort, or -motivation (Study 4). This provides support for our proposed cognitive pathway. Our findings enhance our understanding of the cognitively demanding nature of task proactivity and provide empirical support for its cognitive costs using a mental fatigue lens. They also suggest that the impact of a cognitively demanding activity like task proactivity may persist throughout the day and carry over to other tasks involving cognitive performance.},

abstract = {Consensus adjustment is crucial in group decision making (GDM), aiming to reduce discrepancies in decision makers' (DMs') judgments for final decision results. The consensus adjustments made by DMs are interactive rather than independent. However, few studies investigate the consensus adjustment problem from the perspective of interactions among DMs. This study first constructs a model to determine the total minimum consensus adjustment under the requirements of consensus threshold and individual-collective judgment bias. Then, a consensus adjustment approach based on cross-allocation scheme is proposed to address the inconsistency between individual and collective minimum adjustments, which concerns all DMs' individual favorable allocation results under the total minimum consensus adjustment. The cross-allocation scheme ensures unanimous support for the same allocation result among all rational DMs, thereby eliminating the discrepancies among them. Subsequently, the optimization model-based minimum consensus judgment penalty is formulated to handle the non-cooperative behaviors of DMs. Furthermore, we show how to determine the unique consensus adjustment result for the non-cooperative DMs using the cross-allocation scheme. Therefore, our study contributes by developing a new GDM method that conducts consensus adjustment allocation by considering interactions among DMs. Finally, a case study is employed to demonstrate the specific application of the new method and discuss its efficiency. Meanwhile, comparison analysis and simulation experiments are provided.},

How does the heterogeneity of institutional investors influence corporate tax avoidance? The moderating role of family ownership Article de journal

abstract = {Purpose: This study provides new insights into the relationship between institutional investors' heterogeneity and corporate tax avoidance. It also investigates whether family ownership moderates this relationship.
Design/methodology/approach: Based on a sample of 200 French listed firms from 2008 to 2017, we use the generalized method of moment (GMM) estimator proposed by Arellano and Bover (1995) and developed by Blundell and Bond (1998) to address endogeneity and omitted variable concerns.
Findings: The results show that passive institutional investors are associated with an increase in the level of tax avoidance. However, active ones significantly decrease the levels of tax avoidance practices. Moreover, we show that institutional activism is not sufficient to control managerial actions, particularly in the context of controlled family businesses. The results suggest that families may expropriate the rights of minority shareholders through a controlling coalition with passive institutional investors.
Originality: This paper extends previous research by investigating the heterogeneity of institutional investors' behavior in terms of horizon, ownership, and control. In addition, this paper sheds a new light on how family firms behave regarding tax avoidance practices in presence of active and passive institutional investors.
Research limitations/implications: This study has several practical implications. First, the results are useful for policymakers who should pay more attention to conflicts of interests and constrain passive institutional investors to provide only one service (asset management). Second, this study may sensitize family owners to the need to collaborate with active institutional investors that are effective in the monitoring of the firm. In particular, families should be willing to sacrifice some of their socioemotional wealth to promote balanced ownership structures that exclude investors with business relationships with the company.},

abstract = {This study investigates why and when employees' observations of supervisors' ostracism of coworkers elicit their own feelings of guilt. In this connection, observers' silence might function as a mediator, and leader-member exchange quality could moderate the process. The tests of these predictions rely on two studies, undertaken in Pakistan: a temporally separated field study using three-wave data (N = 219) and a scenario-based experiment (N = 118). The combined results indicate that employees feel guilty for remaining silent when they witness supervisor ostracism of other colleagues. The positive relationship between such observations of supervisor ostracism and silence behavior is more pronounced among employees who enjoy high-quality relationships with their supervisor. In addition to establishing key theoretical insights, this article alerts organizations to a critical mechanism (silence to avoid upsetting supervisors) by which employees' observations of how supervisors ostracize others can escalate into their own sense of guilt.},

We argue that firms are likely to disclose their climate change-related information to gain ethical legitimacy, especially during uncertain times. Using the policy uncertainty measure from Baker, Bloom, and Davis (2016) and an extensive dataset from the CSRwire platform, we provide strong evidence that policy uncertainty is positively associated with releasing climate change-related news. Our findings are robust to alternative measures of policy uncertainty and when controlling for endogeneity. In a set of additional analyses, we show that the industries within which firms operate and their environmental performance are channels that explain the release of climate-related information. Taken together, our results highlight the role that climate change-related information may play in providing firms with ethical legitimacy and building trust among all stakeholders in times of political uncertainty.},

negatively affects companies' environmental responsibilities. In particular, the availability of non-renewable
natural capital leads firms to overexploit resources, leading to weaker engagement in environmental activ-
ities. We also show that the Paris Agreement in 2015 improved the focus of firms operating in natural capital-rich countries on environmental responsibility. Further evidence shows that the influence of natural capital on
corporate environmental responsibility is more prevalent for firms in developing countries and manufacturing
industries. This negative effect also holds for the emission-reduction and resource-use subdimensions of environmental responsibility. However, renewable natural capital positively affects environmental innovation. Our results are robust to endogeneity concerns.},

Using a focal examiner's prior grant rate as an instrumental variable for the patent grant decision, an initial patent grant increases subsequent patent filings by 52.6 percent, indicating an increase in direct cross-border knowledge flows and sustained technological presence by foreign technological entrants. These effects are at least partially driven by an appropriation mechanism, where technological entrants increase subsequent filings for existing inventions -- or inventions already filed in other countries at the time of the initial decision. Securing a patent grant also increases the likelihood of technology spillovers to local U.S. firms by 30.5 percent, highlighting the trade-off between bargaining frictions and knowledge diffusion.},

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.},

However, they struggle to integrate environmental issues into their decision-making processes, especially planning. In the European context of the Sustainable Urban Mobility Plan approach and Strategic Environmental Assessments (SEAs), this paper scrutinises three French localities to determine the current best practices and limitations for designing mobility plans and integrating environmental issues. Several limitations are identified: (1) limited expertise in defining and characterising actions and objectives, which complexifies plans' design, understanding, and monitoring; (2) a lack of a framework to conduct long-term quantitative environmental assessments and to use the results to influence decision effectively; and (3) monitoring processes are barely described in the documents, and the planning horizon where objectives are defined is not in sync with the indicators' mandatory evaluation period. This French case study thus reveals that European planning practices must be further analysed and improved to deal with the rising environmental concerns, e.g. through an operational framework to design mobility plans with effective integration of environmental issues.},

abstract = {Material deprivation and the risk of poverty, exacerbated by recent unexpected events such as the ongoing Ukraine-Russia conflict, are significant social issues that profoundly affect the lives of numerous individuals. In contrast, social robots represent problem-solving innovations that have the potential to contribute to the achievement of the 17 sustainable development goals established by the United Nations. This paper investigates the association between the adoption of social robots and the risk of poverty, while also establishing the connection between the diffusion of social robots and the proportion of individuals experiencing material deprivation. The study involves a sample of 28 European countries and utilizes statistical analysis of data collected from 2018 to 2021.By taking into account variables such as average income and the unemployment rate, our findings indicate a negative association between the utilization of social robots and both the risk of poverty and the proportion of individuals living in material deprivation. Therefore, our research offers theoretical and managerial implications, serving as a basis for policymakers and managers to make informed decisions aimed at improving the standard of living for the most marginalized individuals.},

abstract = {We study the relationship between crude oil price volatility and corporate environmental performance. Using an extensive dataset from 32 countries consisting of 18,464 firm-year observations, we provide strong evidence that oil price volatility significantly increases firms' environmental performance. Our main inference is robust when using alternative measures of oil price volatility and environmental performance, alternative econometric specifications and samples, and several approaches to control for endogeneity. In a set of additional analyses, we first conduct a difference-in-differences analysis that exploits the Arab Spring as an exogenous oil price volatility increase and document a stronger relationship between oil price volatility and environmental performance in the aftermath of the Arab Spring. We second identify (i) capital expenditures and (ii) alternative energy importation as two mechanisms through which oil price volatility influences environmental performance. We finally show that national culture plays a significant role in moderating the relationship between oil price volatility and environmental performance. Taken together, our empirical findings highlight the role of economic uncertainty in affecting firms' environmental performance and provide significant contributions to management and policymakers.},

abstract = {This study aims to investigate the impact of monetary policy on firms' carbon emissions. The primary focus is on the effect of increasing interest rates on the carbon footprint of companies, both prior to and following the implementation of the Paris Agreement in 2015. The results show that there is a positive relationship between interest rates and carbon emissions indicating that in the face of increasing interest rates, companies are more likely to choose short-term financial stability above long-term sustainability objectives. This positive relationship is less prevalent following the Paris Agreement suggesting that policymakers should continue to strengthen global climate initiatives as a pressure for companies to invest in green activities. Additional evidence suggests that the impact of interest rates on carbon emissions is particularly noticeable in situations characterized by elevated levels of economic and policy uncertainty, weak corporate governance quality, and poor investor protection. These results are robust to endogeneity concerns, alternative measures of interest rates, carbon emission, and alternative samples.},

abstract = {The purpose of the paper is to conceptualize and redefine trust within the blockchain ecosystem by exploring the
trust construct across academic disciplines and its applicability in the blockchain context. We develop a conceptual
model and testable propositions that extend the work of McKnight et al. (2001, 2002, 2011) to the
blockchain ecosystem based on an integrative literature review. We conceptualize trust as a multidimensional,
multi-object construct combining three major objects of trust: algorithmic trust in the blockchain protocol
(platform), trust towards peers and services providers, and trust in decentralized applications (product). The
model reflects the process of building a trust layer for users and institutions on top of the trustless technology.
The paper demystifies the trust building process, from initial trust to knowledge-based trust, and its dimensions
within the blockchain ecosystem, and, consequently, helps practitioners to build strategies that increase users'
trust. The contribution to the academic literature resides in the unification of multiple perspectives on trust
within an integrative conceptual framework to point out the mechanisms of trust building process, as well as to
identify future research directions.},
