Causal interactions and financial contagion among the BRICS stock markets under rare events: a Liang causality analysis
Authors: Lu Xunfa , Sun Jingjing , Wei Guo , Chang Ching-Ter 
Published: August 2023

PurposeThe purpose of this paper is to investigate dynamics of causal interactions and financial risk contagion among BRICS stock markets under rare events.Design/methodology/approachTwo methods are adopted: The new causal inference technique, namely, the Liang causality analysis based on information flow theory and the dynamic causal index (DCI) are used to measure the financial risk contagion.FindingsThe causal relationships among the BRICS stock markets estimated by the Liang causality analysis are significantly stronger in the mid-periods of rare events than in the pre- and post-periods. Moreover, different rare events have heterogeneous effects on the causal relationships. Notably, under rare events, there is almost no significant Liang's causality between the Chinese and other four stock markets, except for a few moments, indicating that the former can provide a relatively safe haven within the BRICS. According to the DCIs, the causal linkages have significantly increased during rare events, implying that their connectivity becomes stronger under extreme conditions.Practical implicationsThe obtained results not only provide important implications for investors to reasonably allocate regional financial assets, but also yield some suggestions for policymakers and financial regulators in effective supervision, especially in extreme environments.Originality/valueThis paper uses the Liang causality analysis to construct the causal networks among BRICS stock indices and characterize their causal linkages. Furthermore, the DCI derived from the causal networks is applied to measure the financial risk contagion of the BRICS countries under three rare events.
Paradox-responding in humanitarian temporary supply networks: exploring strategies and enabling mechanisms
Authors: Fernandes Aline Rodrigues , Dube Nonhlanhla 
Published: August 2023

PurposeThis study investigates paradox-responding strategies and enabling mechanisms in humanitarian temporary supply networks (TSNs). Given the high stakes involved in life-saving supply networks, understanding how diverse, often under-resourced, organisations jointly tackle paradoxical tensions under time pressure is crucial.Design/methodology/approachA qualitative single case study approach is adopted and a TSN deployed to meet shelter needs following the 2015 Nepal earthquake is selected as the case. The authors use diverse secondary data sources to establish how the TSN responded to paradoxical tensions.FindingsResults show that paradox-responding in humanitarian TSNs is ongoing, dynamic and a collective effort. Most strategies entail tackling the paradoxical tensions at the same time, using the same TSN structure, but there are differences in the treatment of the paradoxical elements. Additionally, the authors find that the execution of the responding strategies is enabled by the appropriate types of network-level mechanisms which can vary in novelty, complexity, depth and reach.Research limitations/implicationsThis study provides rich explanations of paradox-responding and develops insights into collective action within TSNs. However, further research is needed to extend and refine insights given the single-case setting design.Practical implicationsThis study develops a framework of paradox-responding strategies and a corresponding mix of enabling mechanisms that can guide decision-makers in the humanitarian sector when deploying TSNs.Originality/valueTo the best of the authors' knowledge, this is the first study that investigates paradox-responding strategies in humanitarian TSNs in particular and enabling mechanisms in general.
How having job impact leads to employee innovative behavior: a moderated mediation model of servant leadership and work meaningfulness
Authors: Almazrouei Safeya , Bani-Melhem Shaker , Mohd Shamsudin Faridahwati 
Published: August 2023

PurposeProsocial job characteristics have received the least scholarly attention among the antecedents of employee innovative work behavior (IWB). Hence, antecedents' role remains largely unknown, especially in public sector organizations. Based on the relational job design theory, job characteristics theory (JCT) and public sector innovation literature, the authors examine whether job impact (JI) promotes public sector employees' IWB mediated by work meaningfulness (WM). This study also assesses whether servant leadership (SL) strengthens the influence of JI on IWB (via WM).Design/methodology/approachThe model was examined on a sample of 180 employee-supervisor dyads (90 supervisors and 180 employees) recruited from various government departments in the United Arab Emirates (UAE).FindingsThe finding supports the proposed moderated mediation model in which JI enhances IWB. The association between JI and innovative behavior via WM is found to be stronger under high SL behavior.Originality/valueThe authors' findings offer prescriptive insights into SL's crucial role in illustrating when and how JI promotes IWB and offer relevant managerial recommendations for encouraging public sector employees to demonstrate innovative behavior. The authors also provide empirical evidence on the significant contribution of a prosocial job characteristic, i.e. JI, to IWB. In addition to having theoretical and practical significance, the authors' study is aligned with the UAE National Innovation Strategy 2015.
Identification and prioritization of the factors influencing blockchain adoption in the banking sector: integrating fuzzy AHP with TOE framework
Authors: Kajla Tanveer , Sood Kirti , Gupta Sanjay , Raj Sahil , Singh Harpreet 
Published: August 2023

PurposeThe objective of this research is to identify and prioritize the critical factors that influence the adoption of blockchain technology within the banking sector.Design/methodology/approachA well-known theoretical framework, the “Technology Organization Environment (TOE),” was chosen to analyze what criteria and sub-criteria affect blockchain adoption in the banking sector after a thorough assessment of the prior literature. Following that, 3 evaluation criteria and 14 sub-criteria were selected and verified using expert opinion. A survey design was created, and data for the study has been collected from various information technology (IT) managers/officers in the banking sector. A fuzzy analytic hierarchy process (Fuzzy-AHP) was then used to meet the purpose of the research.FindingsThe study identified that the organizational dimension is the most significant criteria for blockchain adoption in the banking sector, followed by the environmental dimension. In contrast, the technological dimension is the least influential criterion. Clientele pressure, IT resources, financial resources, pressure from competitors and relative advantage are the most influential sub-criteria for blockchain adoption.Research limitations/implicationsThis study provides valuable insights to bank managers, blockchain and IT developers, third-party service providers and policymakers. For instance, adopting the same blockchain platform is easier for both large and small banks for banking operations by using third-party service provider. At the same time, banks should have the banks' own core team to implement the blockchain-based systems or to have control over the third-party service providers during the adoption stage.Originality/valueTo the best of the authors' knowledge, no empirical studies have used a holistic organizational context to understand the factors influencing the adoption of blockchain technology from traditional to blockchain-based banking systems.

Published: August 2023

PurposeSocial commerce (SC) is a new genre in electronic commerce (e-commerce) that has great potential. This study proposes a new research framework to address deficiencies in existing social commerce research frameworks (e.g. the information model).Design/methodology/approachIn the era of Industrial Revolution 4.0 technologies and new social commerce (s-commerce) models, the authors believe that there is an immediate need for a new research framework. The authors analysed the progress of the s-commerce paradigm between 2003 and 2023 by applying longitudinal science mapping. The authors then developed a research framework based on the themes in the strategic diagrams and evolution map.FindingsFrom 2003 to 2010, studies on s-commerce mainly focused on social networking sites, virtual communities, social shopping and analytic approaches. From 2011 to 2015, it shifted to s-commerce, consumer behaviour, Web 2.0, artificial intelligence, social technologies, online shopping, user studies, data gathering methods, applications, service-based social commerce constructs, e-commerce and cognitive factors. Social commerce remained the primary research paradigm from 2017 to 2023.Practical implicationsThe SC framework may be analogous to popular research frameworks such as technology-organisation-environment (T-O-E) and stimulus-organism-response (S-O-R). Based on this SC framework, researchers may gain a better understanding by determining the factors of the social, commercial, technological and behavioural dimensions.Originality/valueThe authors redefined s-commerce and developed an SC framework. Practical guidelines for the SC framework and an exemplary research model are presented. Overall, this study offers a new research agenda for the extant understanding of s-commerce, with the SC framework as the next frontier of the theoretical advancements and applications of s-commerce.

The effect of reinsurance treaties on the cedent loss reserving
Authors: Payandeh Najafabadi Amir T. , Atatalab Fatemeh 
Published: August 2023

Purpose
The usual, simple and computationally expensive recovery payment method for a given reinsurance treaty, besides the total run-off triangle, builds a new run-off triangle, say recovery run-off triangle, for the reinsurer’s contribution and predicts the reinsurer’s contribution to the total loss reserves. This paper, without building a recovery run-off triangle, uses the available prior knowledge about a reinsurance treaty to predict the cedent’s loss reserve under five reinsurance treaties.

Design/methodology/approach
The authors propose a new solution to the problem of how to consider reserving issues when there is a reinsurance treaty for a portfolio of general insurance policies. Considering this when determining pricing or making capital decisions is very important.

Findings
In particular, it considers the quota share (QS) treaty, surplus (SPL) treaty, excess-of-loss (XL) treaty, largest claims reinsurance (LCR) treaty and excédent du coût moyen relatif (ECOMOR) treaty. Then, it develops a theoretical foundation for predicting the cedent’s loss reserve and evaluating such prediction using the mean square error of prediction (MSEP). The impact of such reinsurance treaties on the variability of the cedent’s loss reserve has been investigated through a simulation study.

Prioritization and deployment of design for additive manufacturing strategies to an automotive component
Authors: R. Sakthivel Murugan , S. Vinodh 
Published: August 2023

Purpose
This paper aims to propose a new framework on prioritizing and deployment of design for additive manufacturing (DfAM) strategies to an industrial component using Fuzzy TOPSIS multiple criteria decision-making (MCDM) techniques. The proposed framework is then applied to an automotive component, and the results are discussed and compared with existing design.

Design/methodology/approach
Eight DfAM design alternatives associated with eight design criteria have been identified for framing new DfAM strategies. The prioritization order of the design alternatives is identified by Fuzzy TOPSIS MCDM technique through its closeness coefficient. Based on Fuzzy TOPSIS MCDM output, each of the design alternatives is applied sequentially to an automobile component as a case study. Redesign is carried out at each stage of DfAM implementation without affecting the functionality.

Findings
On successful implementation of proposed framework to an automotive component, the mass is reduced by 43.84%, from 0.429 kg to 0.241 kg. The redesign is validated by finite element analysis, where von Mises stress is less than the yield stress of the material.

Practical implications
The proposed DfAM framework and strategies will be useful to designers, R&D engineers, industrial practitioners, experts and consultants for implementing DfAM strategies on any industrial component without impacting its functionality.

Originality/value
To the best of the authors’ knowledge, the idea of prioritization and implementation of DfAM strategies to an automotive component is the original contribution.
Evaluation of the mechanical properties of polyamide 12 regarding different percentages of reused material in the selective laser sintering process
Authors: da Silva Rafael Couto , Dicati Gabriela Wessling Oening , Gubaua José Eduardo , Radovanovic Eduardo , Favaro Sílvia Luciana 
Published: August 2023

Purpose
Additive manufacturing (AM) has been one of the most highlighted processes of the last few years. AM prints complex parts and items from 3D files regarding different materials, such as polymers. Moreover, there are different AM techniques available for polymers, such as selective laser sintering. In the SLS technology, polyamides 11 and 12 lead 88% of the market. These materials are high-cost and use an average of 50% of virgin material at each printing. It is possible to use lower rates of virgin material, but at least 30% is recommended. Low rates of virgin material decrease mechanical properties.

Design/methodology/approach
This study aims to evaluate the influence on the mechanical properties of the percentage of reused PA12 in parts manufactured by the SLS process. The specimens of PA12 were manufactured with a percentage of virgin/reused polymer of 50/50, 40/60, 30/70, 20/80 and 10/90. We considered three distinct printing directions to compare the mechanical properties of the specimens: horizontal, perpendicular and vertical.

Findings
The results showed that when the percentage of reused material increases, the tensile strength limit (TSL), flexural strength limit and Shore D hardness decrease. Another aspect visualized was the fragile behavior presented in the vertical specimens. In addition, DSC analysis indicated a 2% reduction of crystallinity. Scanning electron microscopy images revealed spherical voids and unfused particles of PA12 at the fracture of tensile test specimens. The material thermal history and unfused particles could decrease the material properties.

Originality/value
We observed that the mechanical properties, such as the TSL, flexural strength limit and hardness, decrease as the percentage of reused material increases. In addition, the process presented a printing-direction dependence, where the vertical direction presented as the more brittle between the ones used.
Warming‐induced functional shifts in the decomposer community interact with plant community compositional shifts to impact litter decomposition
Authors: Dawson‐Glass Emma , Hewins Charlotte R. , Burke David J. , Souza Lara , Stuble Katharine L. 
Published: August 2023

AbstractClimate warming is altering plant and soil microbial communities, with important implications for ecosystem processes like litter decomposition. As warming alters plant community composition, the quality of litter will change. Further, shifts in microbial community activity and/or composition will alter microbial function. However, it is not yet completely understood how these shifts will interact to drive decomposition.We explored how changes in plant and microbial communities interact to influence litter decomposition using a 15‐year‐old grassland warming experiment. Previous studies within this system have shown that warming shifted the microbial community in ways that accelerate litter decomposition while simultaneously shifting the plant community in ways that may slow decomposition. Specifically, warming increased abundance ofSorghastrum nutans, while decreasing abundance of the previously dominantSchizachyrium scoparium. Using a series of lab‐based microcosm experiments, we examined the rate at which eight common grasses and, separately, varying abundances ofS. nutansandS. scopariumdecomposed. Using litter and soil from the warming experiment, we then incubated soils from warmed or control plots with different abundances ofS. nutansandS. scopariumin a reciprocal design.We foundS. nutansto be the slowest‐decomposing grass in our system. Further, decomposition slowed asS. nutansincreased andS. scopariumdecreased. When examining the interaction of plant and microbial communities, decomposition was generally greater early in our experiment as the relative abundance ofS. scopariumincreased. However, soil microbial community origin and litter composition interacted significantly. Specifically, decomposition increased with greater relative abundance ofS. scopariumon soils derived from control plots, while litter composition did not shape rates of decomposition on soils from warmed plots. The influence of litter species on decomposition waned in the later stages of the experiment when decomposition was driven by microbial community origin.These results suggest that warming‐induced changes in microbial community function may interact with changes in plant litter composition to mitigate the impacts of warming on rates of decomposition. This emphasizes the importance of considering concurrent warming‐induced changes in both plant and microbial communities on ecosystem processes like decomposition.Read the freePlain Language Summaryfor this article on the Journal blog.
Wild bee surveys across 60 years reveal remarkable reduction of bee abundance in urban green areas in northern Japan

Published: August 2023

AbstractLong‐term monitoring of wild bee communities at fixed locations using a consistent sampling procedure has been rare, although declines in their diversity and abundance due to anthropogenic impacts are a major concern. At two sites in urban green areas in Sapporo city, northern Japan, where wild bee surveys were conducted in 1959, 1979, 1989, 2018, and 2019, the number of individuals of bee genera was recorded. Patterns of seasonal changes in bee abundance collected at weekly censuses differed between 1979–1989 and 2018–2019. The total bee abundance collected in annual surveys consisting of standardized censuses demonstrated 50% and 41% declines at the two sites from 1959–1989 to 2018–2019. Among the 16 genera found in the surveys, 3 abundant genera, Andrena, Lasioglossum, and Ceratina, always exhibited lower abundance in 2018–2019 than in 1959–1989 at both sites. The remarkable declines in wild bee abundance should be examined in relation to various possible factors of anthropogenic impacts.
Interlocked: kinship, intimate precarity, and plantation labour in India
Authors: Raj Jayaseelan 
Published: August 2023

AbstractThis article examines the employment of kinship relations in sustaining the plantation economy and in perpetuating the precariousness of child labourers who later became temporary workers in the tea plantations of Kerala, South India. Kinship ties locked diverse workers into a moral obligation of care that could easily be manipulated by plantation management as a form of labour control. Plantation capitalism, therefore, sustained itself not only through overt forms of violence but also through manipulating the precarity of employment in relation to intimate forms of love, care, and obligation that were bound up with kinship ties. Kinship networks of different kinds need to be understood as integral to the plantation society and as occupying a fundamental place within the capitalist order of plantations. I observe that the entangled relationship between workers’ precarity and plantation capitalism can be understood only if we pay attention to what I call the intimate precarity produced by the employment of kinship networks within plantation capitalism.
