Buying firms involve suppliers early in New Product Development (NPD) projects to benefit from their capabilities. The authors investigate the joint impact on project performance improvement, of the social capital established throughout the project, and the strategic preferred buyer/supplier statuses awarded prior to the project, from the buyer's perspective.

The authors propose a conceptual model underlining the complementary contribution to project performance of social capital dimensions and of preferred partners' statuses resulting from social exchange expectations. The model is analyzed with Partial Least Squares using 80 responses of purchasers and R&D managers involved in collaborative NPD projects with suppliers.

The relational capital built during the project has a positive central role, with a direct impact on NPD project performance and mediating effects through cognitive and structural capitals. The preferred partners' statuses have strong direct impacts on performance, and mediating effects that do not completely supplant the social capital's contribution.

The implications for the efficient management of supplier involvement are twofold. First, the authors encourage strategic investments of buying firms to acquire preferred buyer's status and to support preferred supplier programs. Second, the authors alert them on the importance of establishing trust and shared cognition during the project.

This study captures NPD project performance from the social angle of buyer–supplier relationship management. It demonstrates the complementarity of relationship management at the strategic and operational levels, before and during the project unfolding.

Educators need to engage in continuous learning to ensure that their knowledge and practice responds to the changing needs of society and students. Collaborative approaches, in which social capital resource is exchanged, can serve as an effective way of facilitating such learning. With this systematic review, the authors identify the opportunities and benefits inter-school social capital networks might bring by exploring: (1) what inter-school networks are available internationally for primary and secondary schools, (2) the features and activities present within inter-school networks and (3) evidence of impact of inter-school network activities.

For this study, the authors employed a systematic review methodology. The review comprised the five stages of the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses: PRISMA, 2021) protocol. The study findings derived from 111 research outputs (from a total of 1,221 originally identified).

The review highlights a number of different inter-school networks and their diverse purposes as well as key network features, such as the actors present in networks and the activities network participants engage with. At the same time, however, the authors only identify limited reliable evidence of the impact of inter-school networks.

The study fills a knowledge gap by exploring, for the first time, the presence, features of inter-school social capital networks available to school leaders as well as investigating the impact of these networks.

This study aims to explore whether and how workplace loneliness leads to cyberloafing and the role of leader problem-focused interpersonal emotion management in buffering this relationship.

Drawing on ego depletion theory, the authors propose that employees' workplace loneliness leads to cyberloafing via ego depletion, while leader interpersonal emotion management (i.e. leadership behavior targeted at managing employees' negative emotions) can help to alleviate the situation. To test this study’s predictions, the authors collected multisource data at three time points from a sample of 219 employee–colleague dyads.

The results show that workplace loneliness is positively related to cyberloafing and that ego depletion mediates this relationship. Leader problem-focused interpersonal emotion management weakens the relationship between workplace loneliness and ego depletion and the indirect relationship between workplace loneliness and cyberloafing via ego depletion such that the above relationships are weak (versus strong) when leader problem-focused interpersonal emotion management is high (versus low).

The study results suggest that workplace loneliness is an important hidden danger that leads to cyberloafing because lonely employees suffer more from ego depletion. Leaders' interpersonal emotion management strategy serves as a potential buffer for such a negative effect.

Concerns have been raised regarding the mental health of firefighters. In response to this, existing literature reviews have highlighted the significant role of trauma in influencing mental health and the experience of post-traumatic stress within firefighters.

This paper builds on the existing reviews and makes an original contribution to knowledge by systematically reviewing research exploring additional factors that contribute to poor mental health in firefighters.

This review finds that factors such as sleep, occupational stress, length of service, coping style and social support all influence negative mental health within firefighters. However, this paper also suggests there are challenges to distinguishing the nature of these relationships, due to the possible bidirectional nature of the relationships and study limitations.

Finally, we conclude by suggesting a clear need for further research to explore the biological, psychological and social factors influencing mental health outcomes in firefighters and the direction of these relationships, in order to inform effective intervention and support.

This study aims to explore the interplay between community dynamics and knowledge production using the quantum computing research field as a case study. Quantum computing holds the promise of dramatically increasing computation speed and solving problems that are currently unsolvable in a short space of time. In this highly dynamic area of innovation, computer companies, research laboratories and governments are racing to develop the field.

After constructing temporal co-authorship networks, the authors identify seven different events affecting communities of researchers, which they label: forming, growing, splitting, shrinking, continuing, merging, dissolving. The authors then extract keywords from the titles and abstracts of their contributions to characterize the dynamics of knowledge production and examine the relationship between community events and knowledge production over time.

The findings show that forming and splitting are associated with retaining in memory what is currently known, merging and growing with the creation of new knowledge and splitting, shrinking and dissolving with the curation of knowledge.

Although the link between communities and knowledge has long been established, much less is known about the relationship between the dynamics of communities and their link with collective cognitive processes. To the best of the authors’ knowledge, the present contribution is one of the first to shed light on this dynamic aspect of community knowledge production.

As firms consider initiatives to enhance their social sustainability performance, supplier diversity, equity and inclusion (DEI) have become significantly more important. As such, the purpose of this study is to theorize, operationalize and develop an empirical scale to measure supplier DEI.

The following three-phase scale development method was used: first, identification of scale items from the literature; second, a qualitative component involving interviews with expert panels; and third, a psychometric evaluation through two survey rounds with 327 managers from multiple areas of supply chain management.

Although not necessarily a new concept, this study provides a more complete understanding of supplier DEI beyond traditional aspects of supplier diversity (e.g. women and minority-owned suppliers) to feature additional considerations (e.g. LGBTQIAP+) and reflect broader societal considerations, such as human rights. Therefore, validated items for the three dimensions (i.e. diversity, equity [human rights] and inclusion) were identified.

This study provides systematically validated scales to measure supplier DEI based on three dimensions. Each dimension can be developed separately from the others, but they are intertwined, which reinforces the contribution to both scholars and practitioners.

This study develops a conceptualization of NPD (new product development) complexity and explores how inter-organizational collaboration and conflict influence NPD performance.

An empirical examination tests the proposed relationships in the context of Korean manufacturing firms, which currently engage in NPD projects with their key partners. Structural equation modeling (SEM) was used to examine the hypotheses.

The findings suggest that a higher level of NPD complexity simultaneously calls for inter-organizational collaboration and conflict, and these two factors influence NPD performance in a conflicting manner: inter-organizational collaboration serves as a driver, and inter-organizational conflict acts as a barrier against NPD performance.

This study provides answers to the academic and practical calls by providing how NPD complexity should be managed in a way to increase NPD performance. This study provides insight into how manufacturing firms form inter-organizational collaboration practices and why they need to mitigate inter-organizational conflict.

The novel COVID-19 supply chain disruption has globally altered the environmental needs of society. Against this backdrop, this paper aims to examine how top managers are environmentally committed to integrating green supply chain management (GSCM) practices in the operational performance of small- and medium-scale enterprises (SMEs) in Ghana, within the post-pandemic economy.

The study used a cross-sectional survey to obtain data from 270 SMEs in Ghana, using partial least squares (PLS) structural equation modelling to test seven hypothesized relationships.

The outcome of the analysis revealed that top management environmental commitment has a significantly positive effect on supply chain operational performance. The structural model also revealed that top management environmental commitment has a positive and significant effect on both internal and external GSCM practices. The results further revealed that both internal and external GSCM practices have positive and significant effects on supply chain operational performance. Finally, both internal and external GSCM practices mediate the path between top management environmental commitment and supply chain operational performance.

The study provides a novel framework which contributes to both theoretical studies and managerial decisions on COVID-19 related supply chain management issues. However, the study was limited to the Ghanaian context, thus, further related studies are required in other contexts.

This study provides a novel framework by elucidating the intervening role of GSCM practices in the path between top management environmental commitment and supply chain operations in an emerging post-pandemic world context.

Inventory models are quantitative ways of calculating low-cost operating systems. These models can be either deterministic or stochastic. A deterministic model hypothesizes variable quantities like demand and lead time, as certain. However, various types of research have revealed that the value of demand and lead time is still ambiguous and vary unanimously. The main purpose of this research piece is to reduce the uncertainties in such a dynamic environment of Industry 4.0.

The current study tackles the multiperiod single-item inventory lot-size problem with varying demands. The three lot sizing policies – Lot for Lot, Silver–Meal heuristic and Wagner–Whitin algorithm – are reviewed and analyzed. The suggested machine learning (ML)–based technique implies the criteria, when and which of these inventory models (with varying demands and safety stock) are best fit (or suitable) for economical production.

When demand surpasses a predicted value, variance in demand comes into the picture. So the current work considers these things and formulates the proper lot size, which can fix this dynamic situation. To deduce sufficient lot size, all three considered stochastic models are explored exclusively, as per respective protocols, and have been analyzed collectively through suitable regression analysis. Further, the ML-based Classification And Regression Tree (CART) algorithm is used strategically to predict which model would be economical (or have the least inventory cost) with continuously varying demand and other inventory attributes.

The ML-based CART algorithm has rarely been seen to provide logical assistance to inventory practitioners in making wise-decision, while selecting inventory control models in dynamic batch-type production systems.

My way or the highway: A stronger partner in humanitarian relief collaboration often seeks control over its weaker partners by leveraging diverse power tactics that may be non-coercive or coercive in nature. In this backdrop, this research accentuates the perspective of weaker partners to understand how a weaker partner drives collaborative synergy under power tactics. Weaker partner in the collaborative dyad resembles the humanitarian organization (HO) who is less capable in terms of access to resources. This partner is further dependent on the stronger HO's directives to participate in the relief work.

Based on social exchange theory (SET), a collaborative dyad in humanitarian relief work is visualized from the perspectives of power and power disparity. In terms of power, mediated power tactics such as legal, coercive and reward powers are considered. Disparity recognizes the presence of a stronger and a weaker partner. Set also magnifies the insight on conflict and trust that can respectively hamper and improve the synergy between partners. In total, 295 executives representing self-reported weaker HOs are surveyed.

Legal power, as experienced by the weaker partner, bears a positive impact over collaborative performance to improve collaborative synergy. Coercive power shows a negative impact. Reward power again bears a positive impact. Coercion can complicate collaborative synergy by establishing conflicts. Yet, the trust of weaker partner on stronger HO positively moderates the negative impact of conflict over collaborative performance.

This research invokes the view of power disparity to explain synergy in inter-organizational collaboration from the perspective of weaker partners.
