Engaging suppliers in joint innovation can be an effective means for buyer firms to overcome internal resource/capability limitations. The purpose of this research is to investigate the impacts of cultural and trust congruences between the supplier and buyer firms on joint innovation. In addition, we examine the relationship commitment as an antecedent of cultural and trust congruences.

The study constructs a theoretical model based on social exchange theory (SET) and examines it using data from Chinese manufacturing firms.

The results suggest that cultural and trust congruences between suppliers and buyers positively influence joint processes and product innovations. Furthermore, we find that while normative relationship commitments of supplier firms promote cultural and trust congruences with buyers, instrumental relationship commitments only positively affect trust congruence.

This study enhances our understanding of social exchanges by adopting a dyadic view to examine the interconnectedness between relationship commitment, cultural and trust congruences, and joint innovation. These findings also offer practical managerial implications for managing collaborative innovation projects.

The European Union (EU) and Russia are considered to be trapped into security concerns in a form of spillover, in a zero sum perspective, considering each step of the other as directed against another. Such an approach seems to prevail, after attempts of engagements for decades after the Cold War. Rather history prevailed in informing perceptions and currently driving the behaviors toward each other, in other words in othering each other.

Discourse analysis

The move in Eastern Europe of both parties is perceived with suspicion from both sides, materialized through their policies, culminated in clash of interests and crash of policies between both parts, manifested by Russian aggression in Ukraine in 2014 and recently in 2022 in one side, and the EU response through massive, unprecedented sanctions against Russia. This has created a context that fosters not just keeping a status quo of clash and struggle for influence between them in the region, but also nourishes further securitization of their respective policies toward the Eastern Europe and beyond. In 2014 and more recently in 2022 Russian aggression in Ukraine, the EU and Russia appear to have the same image to each other as they had during the Cold War, or even beyond. Having this in mind, this paper will address those developments, with particular focus on attempts to avoid them, the failure to do so and how they are impacting the EU, Russia and global politics in a form of emerging new world (dis)order.

This paper is an original paper having a critical approach toward the current conflicts going on in Eastern Europe.

The primary objective of this paper is to investigate the relation between the joint provision of sustainability assurance and the readability of sustainability assurance statements. Additionally, it explores whether the presence of a female assurance partner influences the relation between the joint provision of sustainability assurance and the readability of sustainability assurance statements.

We analyzed a dataset comprising 882 firm-year observations from companies operating in sustainability sensitive industries for the period that spans the years 2016–2018.

The research indicates that joint sustainability assurance provision is associated with a more readable sustainability assurance statement, consistent with the “four-eyes” principle. Furthermore, the presence of a female assurance provider influences the joint assurance provision’s impact on sustainability assurance statement readability. Collectively, these results remain robust as they hold unchanged after controlling for endogeneity concerns.

This study provides novel insights into the recent sustainability assurance literature, being the first to examine joint assurance provision, assurance partner gender and sustainability assurance statement readability.

This study has the potential to catalyze regulatory and policy initiatives by providing compelling evidence in favor of mandating joint audits within the area of sustainability assurance practices. Additionally, this research contributes to the ongoing discussion about gender diversity in accounting and nonaccounting assurance firms, providing evidence of the positive impact of female assurance partners on sustainability assurance statement readability.

The regression results provide preliminary evidence on how the presence of a female audit partner influences the relationship between the sustainability assurance joint provision and sustainability assurance statement readability, an issue that has not been examined before.

Linguists classify the world’s languages into two types: futured and futureless. Futured languages (e.g. French) require speakers to grammatically mark future events, a construction that is optional in futureless languages such as German. This treatise examines whether the grammatical structure of the predominant language in a given country explains firms’ propensity to engage in controversial marketing and environmental management practices. This is expected to happen because a speaker’s future time perspective and temporal discounting vary depending on the type of language used.

The sample period for this research was from 2001 to 2020. The sample of the study consists of 5,275 firms representing 47 countries. The sample is comprised of firms from 29 countries where the predominant language is a strong future time reference (FTR) language and 18 countries with a weak-FTR language. The maximum number of firm-country-year observations of the study was 39,956. This study employed multi-level mixed effects modelling as well as other relevant estimation techniques such as random effect panel regression, ordinary least square regression and two-stage least square regression.

This research empirically demonstrates that firms based in countries where the predominant language requires speakers to grammatically differentiate between the present and the future – known as strong-FTR or futured languages – engage more often in controversial marketing- and environment-related practices than those located in countries where the predominant language does not necessarily require grammatical differentiation between the present and the future (known as weak-FTR or futureless languages).

The findings are important for managers of firms with foreign subsidiary operations: top management teams of such firms need to be aware that their foreign subsidiaries’ propensity to engage in controversial marketing and environmental management practices varies depending on the predominant language those subsidiaries use. Also, firms located in countries with weak-FTR languages need to be more rigorous in their selection process when considering forming a joint venture or acquiring a firm in countries with strong-FTR languages.

The current research enriches the burgeoning body of literature on the effect of language on corporate decision-making. It extends the body of knowledge on the impact of language structure on firms’ inclination to engage in controversial marketing and environmental management practices.

The purpose of this paper is to improve the problem of kinematics incompatibility of human–exoskeleton in the existing rigid lower-limb exoskeleton (LLE).

In this paper, following an introduction, the motion characteristics of the human knee joint and the design method of the exoskeleton were introduced. A kinematics model of the LLE based on cross-four-bar linkage was obtained. The structural parameters of the LLE mechanism were optimized by the particle swarm optimization algorithm. The predefined trajectories used in the optimization process were derived from the ankle joint, not the instantaneous center of rotation of the knee joint. Finally, the motion deviation of the optimization result was simulated, and the human–exoskeleton coordination experiment was designed to compare with the traditional single-axis knee joint in terms of comfort and coordination.

The lower limb exoskeleton mechanism obtained in this paper has a good tracking effect on human movement and has been improved in terms of comfort and coordination compared with the traditional single-axis knee joint.

The customized exoskeleton design method introduced in this paper is relatively simple, and the obtained exoskeleton has better movement coordination than the traditional exoskeleton. It can provide a reference for the design of lower limb exoskeleton and lower limb orthosis.

Recent trends have shown the integration of Chinese word segmentation (CWS) and part-of-speech (POS) tagging to enhance syntactic and semantic parsing. However, the potential utility of hierarchical and structural information in these tasks remains underexplored. This study aims to leverage multiple external knowledge sources (e.g. syntactic and semantic features, lexicons) through various modules for the joint task.

We introduce a novel learning framework for the joint CWS and POS tagging task, utilizing graph convolutional networks (GCNs) to encode syntactic structure and semantic features. The framework also incorporates a pre-defined lexicon through a lexicon attention module. We evaluate our model on a range of public corpora, including CTB5, PKU and UD, the novel ZX dataset and the comprehensive CTB9 dataset.

Experimental results on these benchmark corpora demonstrate the effectiveness of our model in improving the performance of the joint task. Notably, we find that syntax information significantly enhances performance, while lexicon information helps mitigate the issue of out-of-vocabulary (OOV) words.

This study introduces a comprehensive approach to the joint CWS and POS tagging task by combining multiple features. Moreover, the proposed framework offers potential adaptability to other sequence labeling tasks, such as named entity recognition (NER).

This study aims to explore whether and how the two potential antecedents (i.e. relationship quality at the dyadic level and network density at the network level) affect firms’ internet-interactive capability (FIIC), referring to the capability of a specific firm to communicate and interact with the relevant partner firms on the basis of internet-interactive technologies in the internet environment and, at the same time, the following influence of FIIC on collaborative activities (i.e. joint planning and joint problem-solving).

This study designed a questionnaire and collected data on-site from 400 manufacturers. SmartPLS is used to validate the research model.

The results suggest that the dyadic relationship quality and network density of the partner group are both positively connected with a firm’s FIIC. Besides, FIIC is positively related to collaborative activities with its partners.

Given the nature of our data (i.e. cross-sectional), the authors can collect longitudinal or experimental data to retest the hypotheses.

This study gives certain guidance for firms to be aware of the factors that motivate FIIC and use their FIIC to influence their employees’ collaborative activities in their relationships with partners, thereby promoting cooperation performance.

This study attempts to extend the resource-based theory based on the logic of motivation-capability by exploring the potential antecedents of FIIC and makes contributions to the current studies on the antecedents of FIIC, which provides actionable insights for firms to play the role of FIIC in interfirm interactions.

Composite materials are effective alternatives for rehabilitating critical members of offshore platforms, bridges, and other structures. The structural response of composite reinforcement greatly depends on the orientation of fibres in the composite material. Joints are the most critical part of tubular structures. Various existing studies have identified optimal reinforcement orientations for a single load component, but none has addressed the combined load case, even though most practical loads are multiplanar.

This study investigates the optimal orientation of composite reinforcement for reducing stress concentration factors (SCF) of tubular KT-joints. The joint reinforcement was modelled and simulated using ANSYS. A parametric study was carried out to determine the effect of the orientations of reinforcement in the interface region on SCF at every 15° offset along the weld toe using linear extrapolation of principal stresses. The impact of orientation for uniplanar and multiplanar loads was investigated, and a general result about optimum orientation was inferred.

It was found that the maximum decrease of SCF is achieved by orienting the fibres of composite reinforcement along the maximum SCF. Notably, the optimal direction for any load configuration was consistently orthogonal to the weld toe of the chord-brace interface. As such, unidirectional composites wrapped around the brace axis, covering both sides of the brace-chord interface, are most effective for SCF reduction.

The findings of this study are crucial for adequate reinforcement of tubular joints using composites, offering a broader and universally applicable optimum orientation that transcends specific joint and load configuration.

The aim of this research was to investigate fans’ responses toward a sponsor that has had a long-standing sponsorship deal with a club and decided also to sponsor the club’s rival.

A long-term sponsorship deal between a retsina wine company and a popular football club and a newly established deal between the company and the main rival club were selected as the research setting. Data were collected from a total sample of 302 participants, fans of the two teams, using an online survey and PLS-SEM was employed to test the relationships of the proposed structural model.

The results provided evidence for the importance of the inclusion of perceptions of fit for both teams to the model as it impacted the responses in the joint sponsorship. Team identification emerged significant for improving fans perceptions of fit between the sponsor and their favorite club but also led fans of the long-term sponsored club to feel betrayed from the sponsor. The sense of betrayal impacted the level of fit, the rejection of sponsorship but did not emerge significant for driving negative responses toward the sponsor’s brand. The same held for the rejection of the joint sponsorship.

This is the very first study that incorporated the effects of the perceptions of fit of two rival clubs to test the effect of sponsorship for a sponsor brand of a deal that includes a longtime sponsored football club and its rival as a newly sponsored one. It is also one of the first attempts that explores relationships between perceptions of fit, sense of betrayal and rejection of a joint sport sponsorship in a rivalry context, highlighting the importance of preventing fans' betrayal.

As the demand for human–robot collaboration in manufacturing applications grows, the necessity for collision detection functions in robots becomes increasingly paramount for safety. Hence, this paper aims to improve the existing method to achieve efficient, accurate and sensitive robot collision detection.

The external torque is estimated by momentum observers based on the robot dynamics model. Because the state of the joints is more accessible to distinguish under the action of the suppression operator proposed in this paper, the mutated external torque caused by joint reversal can be accurately attenuated. Finally, time series analysis (TSA) methods can continuously generate dynamic thresholds based on external torques.

Compared with the collision detection method based only on TSA, the invalid time of the proposed method is less during joint reversal. Although the soft-collision detection accuracy of this method is lower than that of the symmetric threshold method, it is superior in terms of detection delay and has a higher hard-collision detection accuracy.

Owing to the mutated external torque caused by joint reversal, which seriously affects the stability of time series models, the collision detection method based only on TSA cannot detect continuously. The consequences are disastrous if the robot collides with people or the environment during joint reversal. After multiple experimental verifications, the proposed method still exhibits detection capabilities during joint reversal and can implement real-time collision detection. Therefore, it is suitable for various engineering applications.
