PurposeThis study tries to identify important criteria and sub-criteria for the evaluation of suppliers for effective management of supply chain sustainability risks (SCSR). This study also demonstrates the application of the analytic hierarchy process (AHP) method in a specific case of a company that is managing a short food supply chain and facing difficulty in ranking the suppliers on three dimensions of sustainability.Design/methodology/approachLiterature reviews and expert opinions are used to identify and assess the sub-criteria for each of the three dimensions of sustainability, followed by pairwise comparison as per the AHP methodology. Finally, the proposed framework is used to evaluate the three suppliers that represent approximately 70% of the total tea sourced by the case company.FindingsNone of the three suppliers is best on all three dimensions of sustainability. The rank order of suppliers together on the three dimensions is different than the rank order with respect to each of the dimensions separately. The results obtained are useful for the case company to understand the risk associated with each of their suppliers. Also, it helps them develop a proactive plan to address those risks. The results also show that the overall country-level indices may not accurately reflect the individual supplier level, and specific information may help to make better judgements.Research limitations/implicationsThe study only demonstrates the evaluation of tier-one suppliers. There are various suppliers in the supply chain (tier two and tier three), and there could be missing or inadequate information about these next-level suppliers that augments SCSR substantially. The study focussed on the countries of three specific suppliers, and sustainability parameters are highly contextual and vary from country to country.Practical implicationsThis study proposes a multi-criteria decision framework to evaluate and analyse suppliers based on their performance against SCSR. Using the AHP method, a case application is demonstrated for sustainable supply chain risk management. By considering SCSR in the evaluation process, the case company is able to prioritise prevailing risks, analyse suppliers' positions against these risks and initiate appropriate risk management strategies. The proposed framework provides a powerful tool for making SCSR decisions in similar contexts.Social implicationsThe results helped the company to effectively and efficiently prioritize SCSR and rate suppliers using the proposed framework. It is also observed from the results that the social criterion related to human rights (0.161) was highest in the case company's priority, followed by child labour (0.118). This fact adds value to the proposition that although social sustainability has featured less in academia, it is unclear whether this is apparent in practice.Originality/valueThe study uses experts from a case company based in the UK which is in the business of procurement and supply of tea and is managing a short food supply chain. The framework is the first of its kind using all three dimensions of sustainability: environmental, social and economic.

While large humanitarian organizations (HOs) such as the United Nations Humanitarian Response Depot preposition relief items at strategic hubs during the preparedness phase, many local HOs procure relief supplies only after assessing beneficiaries' needs in the response phase. This often leads to procurement and last-mile distribution challenges due to disrupted road infrastructure, coordination issues, and inequitable aid distribution, resulting in severe shortages of relief supplies and ultimately aggravating the beneficiaries suffering. This paper addresses these gaps by proposing an integrated framework for effective procurement and equitable last-mile distribution in disaster response operations. Driven by practice, we analyse buyback and options contracts accounting for the beneficiary's deprivation cost to coordinate the procurement process between the HO and the supplier under varying road conditions. Subsequently, we develop a multi-period last-mile relief distribution model that bridges the gap between the HO and the beneficiaries and accounts for social costs, fleet capacity, and uncertain demand. The integrated analytical framework aims to provide a sequential map of the procurement and last-mile distribution, enhancing the three critical metrics of humanitarian logistics: efficiency, effectiveness and equity. A case study of the Assam Floods validates the framework, demonstrating its potential to improve disaster response outcomes by addressing procurement and last-mile distribution challenges in real-world scenarios. Lastly, this study offers several managerial implications for humanitarian practitioners working in disaster response operations.

Research on digital platforms has paid scant attention to the entanglement of digital platforms with physical spaces, their interactions, and associated tensions. The entanglement is of increased consequence in the wake of ontological reversal wherein digital constructs the physical. Using Lefebvre's spatial triad of perceived, conceived, and lived space to study digital platform ecosystems, this paper argues that digital platforms through the production of digital space have dramatically transformed the access, experiences, and meanings of the offline physical spaces, thereby emerging as co-producers of contemporary physical space. We illustrate that this process of co-production can lead to gradual emergence of tensions that arise due to the divergence between conceived and lived space and the essential differences in the rationalities of physical and digital space. In doing so, we develop a new spatial understanding of how tensions emerge and build in digital platform ecosystems.

In the policy discourse on urban poor, the homeless - including hawkers, pavement dwellers and evicted slum dwellers, among other groups - have been understood as a 'crisis in the city'. Seen as encroachers and the result of failed urban planning, laws and judicial interventions have not given them the space in cities that they have demanded through litigation. Instead, one observes a re-emphasis on referring to these groups as a 'challenge of urban crisis', or illegal occupants, primarily through begging prevention legislation that has criminalized the urban homeless. This paper describes how the legal situation, through laws such as the Bombay Prevention of Begging Act (BPBA) 1959, creates difficult lives for those who participate actively in the life of the city. I argue for the amendment of a colonial law that serves to criminalize and exclude the homeless in India's metropolitan cities.

PurposeEngaging consumers with brands to generate multiple benefits has become critical for the firms. In this direction, this paper aims to study perceived brand authenticity's role in engendering online brand community engagement. Brand commitment and positive word of mouth were tested as the outcomes of online brand community engagement. This paper also examines the moderation of psychological brand ownership.Design/methodology/approachA theoretically robust model based on relevant literature on online brand community engagement is tested using data from 428 users of various firm-hosted brand communities.FindingsPerceived brand authenticity's three dimensions, i.e. credibility, continuity and symbolism, emerged as predictors of online brand community engagement. Brand commitment and positive word of mouth were also established, stemming from online brand community engagement. Also, psychological brand ownership partially moderated the relationship between perceived brand authenticity and online brand community engagement.Research limitations/implicationsFuture studies are suggested to test this framework's relevance in other contexts to capture the essence of online brand community engagement.Originality/valueThis study demonstrates perceived brand authenticity as a vital precursor to online brand community engagement. Second, the study offers brand commitment and positive word of mouth as valuable outcomes of online brand community engagement. Third, current work establishes psychological brand ownership as a moderator in the context of authentic brands.

Social media engagement (SME) is crucial for sports clubs to build strong relationships and realise financial gains. To drive SME, sports clubs must focus on 'what to post' and 'how to communicate it' on social media. The research addresses this by studying the impact of informational and non-informational cues embedded in social media posts. This study draws upon the elaboration likelihood model (ELM) of persuasion. We identify five features (content type, language complexity, visual complexity, media richness, and content sentiment) influencing users' SMEs. A qualitative content analysis is conducted to classify the content type, while the Linguistic Inquiry and Word Count (LIWC) dictionary is used to analyse the linguistic characteristics of the social media posts. Finally, Poisson regression analysis investigates the effect of content characteristics on SME measures, namely likes, comments, and shares on Facebook posts. A total of 1,880 Facebook posts (registering over 45 million impressions) by four cricket clubs from the Indian Premier League were analysed. The study empirically validates content features that aid/impede information processing to positively/negatively impact users' SME. This research contributes to social media communication by demonstrating linguistics as an effective approach to enhancing SME outcomes.

Traditional project control is inadequate for complex projects like oil and gas (O&G) infrastructure projects, as evidenced by their persistent underperformance. The objective of this study is to explore the dimensions of project monitoring and control (M&C) from a holistic viewpoint on project control and performance. An empirical study was conducted using a multi-method approach for data collection and qualitative analysis within the context of O&G projects in India. The findings reveal a comprehensive framework of nineteen core processes (i.e. dimensions) of project M&C, which extend beyond the conventional control. The results also indicate that all the M&C dimensions, as a control package, impact the project's overall performance. The findings emphasize the M&C processes such as monitoring project-closure, resource & procurement, compliance and team (performance), and communication & coordination (control), change control and project risk M&C. Thus, the study presents a holistic perspective on project control, based on the 'management control system,' transcending the traditional methods to identify various managerial elements of project M&C aimed at enhancing performance. Its practical implications lie in the framework's integrated approach, focusing on key processes of project M&C during execution, for improved performance management in infrastructure projects, particularly in the Indian O&G projects.

PurposeThe concept of employee voice encompasses both promotive voice (PmV) and prohibitive voice (PbV), with PmV representing the affirmative facet that resonates strongly with the ethos of positive organisational scholarship (POS). The purpose of this paper is to explore the alignment between PmV and the core principles of POS. This paper embarks on a quest to enrich the existing literature by contextualising PmV through the prism of POS, thereby furnishing invaluable insights for future scholarly discourse.Design/methodology/approachThis paper uses a storytelling approach encompassing key steps: narrative conflict, main characters, narrative setting, event sequencing, disciplined imagination and the creation of a new narrative. By combining theoretical insights from storytelling with empirical findings from meta-analysis, this study conceptualises PmV within the POS domain.FindingsPmV is theorised as Positive Voice because a discerning analysis reveals that PmV inherently embodies a positivity-infused demeanour, coupled with a forward-looking stance - an attribute conspicuously akin to that of a POS construct.Research limitations/implicationsThis paper contributes to the existing body of literature on PmV, deepening its conceptualisation as a construct within POS. It encourages future research to examine PmV's broader positive impact across organisational contexts.Originality/valueThe existing literature remains silent on the necessity of situating PmV within the POS framework. Through this work, the authors seek to theorise positive voice and its relevance in this context.

Background: In today's demanding work environments, employees' subjective well-being is declining, contributing to an elevated employee turnover rate. Leveraging ability-motivation-opportunity (AMO)-enhancing HR practices has emerged as a promising approach to address this issue and improve subjective well-being. While existing research extensively examines the relationship between HR practices and subjective well-being, a comprehensive conceptual model detailing the nuanced interplay between AMO bundles and subjective well-being remains underexplored. Objective: The study aims to identify and classify various categories of HR practices within the AMO framework and develop an integrative conceptual model linking AMO practices to subjective well-being. Methods: A systematic review of 43 peer-reviewed articles published between 2000 and 2025 was conducted using an inductive content analysis approach. The articles were selected in accordance with the inclusion and exclusion criteria of the PRISMA framework. Results: The findings identify HR practices categorized within the AMO framework, comprising two ability-enhancing practices (conducting training and development programs, recruitment practices), four motivation-enhancing practices (psychological support, incentives and rewards, building meaningful relationships, and flexible working hours), and three opportunity-enhancing practices (participation and involvement, job enrichment, and career advancement opportunities). These practices were shown to enhance employees' subjective well-being significantly. Conclusion: The study offers actionable insights for managers, emphasizing the importance of implementing AMO-driven HR practices as cohesive bundles rather than in isolation to maximize their impact on subjective well-being. Notably, employees demonstrated a strong preference for motivation-enhancing practices, followed by opportunity- and ability-enhancing practices. Additionally, the study suggests that managers integrate artificial intelligence (AI) within HRM systems to further improve employees' subjective well-being substantially. This study contributes to the strategic HRM and well-being literature by developing a comprehensive conceptual model that elucidates the intricate relationships between AMO bundles and subjective well-being.

The present study addresses the critical realm of leadership behaviours that can help improve employee adaptive performance. Responding to this vital workforce performance demand, the current research identifies superior-expressed humility as a potential precursor of adaptive performance. Grounded in the self-determination and social-cognitive theories, the study sheds light on the motivational mechanisms underlying the association between superior-expressed humility and adaptive performance, highlighting the mediating influence of harmonious passion. Additionally, the study explores the moderating influence of occupational self-efficacy between harmonious passion and adaptive performance. The data were gathered through vignette-based surveys from 450 superior-subordinate dyads from Indian Small and Medium-sized Enterprises. AMOS and SPSS Hayes PROCESS Macro were used to analyse the data and test the hypotheses. The findings revealed that the positive association between superior-expressed humility and adaptive performance is partially mediated via harmonious passion. Moreover, the study yielded intriguing results that challenge conventional assumptions regarding the interplay between occupational self-efficacy, harmonious passion and adaptive performance. By illuminating a novel mediated moderation model, the present research, thus, provides human resource professionals and organizational leaders with empirically grounded insights to cultivate an adaptable workforce.

This study addresses the critical need to transition supply chains (SCs) to a circular economy model to reduce energy consumption and carbon emissions, underscoring that circular change requires the active involvement of all SC partners, not just manufacturers. Using a mathematical modeling approach, this study assesses how carbon caps, carbon trading, carbon taxes, and a two-level trade credit policy impact SC profitability, energy reduction, and green technology adoption within a circular economy framework. The models consider scenarios in which supplier demand is credit dependent and retailer demand is uncertain for deteriorating products, focusing on the challenges posed by credit dependency and demand volatility. Numerical results validate its effectiveness in achieving a circular SC for deteriorating products. Key findings show that in a carbon taxation, carbon emission (CE) model, suppliers and retailers attain the lowest costs, smaller order quantities, stable cash flow, and greater green technology investments when credit periods are shorter than replenishment times, effectively reducing energy consumption. In a carbon cap-and-trade CE scenario, both costs and green technology investments are lower when the credit period and carbon credits offered are shorter than the replenishment time, thus favoring both cash flow and sustainability. Under strict CE regulations, if credit periods exceed replenishment times, SC partners can achieve optimal costs, moderate order quantities, favorable payment terms, and high green technology investments, which significantly reduce overall energy use and emissions. A sensitivity analysis established the validity and effectiveness of the model in promoting energy savings, reducing carbon emissions, and minimizing SC costs. The analysis also determined the optimal energy consumption rate across various operations and the energy usage of vehicles to maximize profitability. This study offers a comprehensive perspective on balancing economic sustainability and environmental goals in SCs for deteriorating products under uncertain demand.

Newtonian fluids fail to accurately model fluid flow behavior in various physical scenarios due to their non-Newtonian nature. This article delves into an analytical investigation of how chemical reactions impact the onset of rotating convection in a Couple-Stress (CS) fluid. Utilizing linear stability theory, we derive equations for both stationary and oscillatory Rayleigh numbers. Graphical representations illustrate the influence of key parameters such as the C's fluid parameter, solutal Rayleigh number, Damkohler number, Lewis number, and Prandtl number on the onset of convection. The Lewis and Taylor numbers act to stabilize the system, with the Damkohler number exerting differing effects on oscillatory and stationary convection. Stationary instability is reached when the Taylor number is below 910.331, with oscillatory convection prevailing otherwise. If the Damkohler number is less than 1.76455, oscillatory instability occurs, while stationary convection dominates otherwise.

Purpose - Short food supply chains (SFSCs) have been extensively researched for their environmental and economic implications. However, these are now confronted with shortcomings such as supply chain resilience (SLR) and societal livelihood (SL) hindering growth. The purpose of this study is to revisit and critically analyze existing SFSC literature, with a focus on SLR, SL, sustainability and human-centricity elements, to propose redesigning attributes for SFSCs in the era of Industry 5.0. Design/methodology/approach - The systematic review scope is confined to the SFSC domain with an analysis of contemporary articles published in the British Food Journal (BFJ). The meta-data and research papers are sourced from the Scopus database and the VOSviewer software is used for the analysis. The thematic, diversified geographies and method-wise investigation bring theoretical insights toward building sustainable and resilient SFSCs. Findings - The study findings could serve as a fitting theoretical framework to redesign the SFSCs for resiliency, sustainability and societal aspects of the economy, environment and human livelihood, respectively. The results also discuss the prior accomplishments and elaborate on avenues for future research. Research limitations/implications - Emphasizing recent trends, challenges, policy design, conceptual framework and future research directions for the SFSC domain, considering SLR and SL, has extended the literature in line with the United Nations' Sustainable Development Goals. Practical implications - This study offers comprehensive guidelines to the concerned stakeholders for redesigning the SFSCs by linking sustainability, resilience and societal livelihood dimensions. Originality/value - The study derives comprehensive insights into how redesigning SFSCs has contributed to more sustainable and resilient food systems worldwide over 2 decades. It extends the BFJ's literature body by establishing the linkages between SLR and SL concerning human-centric SFSC.

The increasing frequency and complexity of cyber threats have necessitated the investigation of cyber security preparedness beyond individual level. To do so, we use social action theory and employ path analysis involving value-oriented and instrumental actions as antecedents of cyber-crime and Cyber Security Preparedness (CSP). We found a significant impact of value-oriented and instrumental actions on cybercrime using global indicators as constructs. We found society's level of education as the only instrumental action impacting CSP. Our research contributes to cyber security literature bringing forward a unique instrumental requirement for cyber security preparedness. While affluent economies have all the resources needed to promote CSP, our present examination reveals that countries remain under-prepared without the said instrument. On the contrary, the same instrument is also responsible for their over-preparation even when not required.

PurposeSocial networks can not only mobilize individuals for collective action but also pose risks, potentially leading to political challenges and societal unrest. Information consumption varies across platforms, with platform characteristics influencing user interactions and information sharing; yet this has received limited attention in scholarly literature. Acknowledging platform-specific differences, this paper seeks to enhance our understanding of the mechanisms driving information diffusion on social networks in the context of geopolitical tensions.Design/methodology/approachThe structural communication features on Twitter and Reddit are explored using schema theory and the concept of social media platform schema. Comparisons are drawn with social network analysis and content analysis of communication dynamics surrounding geopolitical tensions in India-Qatar relations, followed by the context of geopolitical tensions between India and Pakistan.FindingsThe results illustrate how content-based connections on Reddit foster closer ties within subreddits but less connectivity between them, contrasting with Twitter's profile-based connections. These distinct characteristics lead to varied information diffusion patterns and shape the diversity of opinions, influencing community structures and affecting the emotional tenor of discourse.Originality/valueSocial networks can potentially influence geopolitical events, but focusing on one platform overlooks differences in how information spreads and the influence each platform holds. Recognizing this, our comparative analysis of social networks' structural attributes highlights their crucial roles in shaping user engagement and information diffusion. It lends theoretical support to the notion of social media platform schema with empirical insights into how users' perceptions of these schemas impact thematic and emotional differences in platform discourse related to geopolitical tensions.

PurposeThe purpose of the paper is to systematically identify and analyze the key factors influencing Metaverse adoption within the supply chains of small enterprises. It aims to employ the Technology-Organization-Environment (TOE) framework to methodically assess the technological, organizational and environmental factors impacting adoption. Additionally, the paper seeks to unravel the interconnectedness between enablers and barriers to provide insights that can inform strategies for enhancing Metaverse adoption among small-scale enterprises.Design/methodology/approachThe paper is a structured literature review to reveal major influencing factors for the adoption of the Metaverse. In terms of the theoretical background, this study bases itself on the TOE framework and employs common factor analysis (CFA) to both establish barriers and enablers toward its adoption. Using interpretive structural modelling (ISM) the paper uncover interrelation complexities between variables. Further richness to such insights was attained with the help of interviews carried out with service providers who have been dealing in Metaverse, giving further clarity regarding the variables adopted that pertain to micro and small enterprises.FindingsThe study identifies important enablers, such as virtual and augmented reality in addition to important barriers, such as technological challenges in adopting the Metaverse in the context of small business supply chains. These factors have been explored with the help of the complex interconnections revealed using ISM within the framework of TOE and CFA. This therefore puts a great deal of managerial relevance in terms of organizational support and technological investment to enable integration and provide strategic insights towards this transformative technology in managing the supply chain and similar disciplines.Originality/valueThis paper demonstrates innovation through the proper application of the TOE framework and CFA of Metaverse adoption within supply chains of small enterprises to classify and analyze the salient enablers as well as barriers. The above contribution offers a fresh and new perspective on the complex sets of factors that influence the Metaverse adoption decision, coupled with the depth added by an application of ISM to the intricate relationships among them. Noting the sample size, this study is rich to the field by providing valuable insight into Metaverse adoption. The findings greatly contribute to future research work and guide practical applications for new emerging areas like supply chain management.

This research investigates the impact of different communication strategies (investment-oriented vs. collaboration-oriented) on luxury perception (LP), consumer value (CV) and willingness to pay (WTP) in luxury hotels. Employing a two-cell between-subjects survey experiment with 242 participants, the study shows how investment-oriented strategies, featuring technological and environmental investments, improve LP and consumers' WTP more significantly than collaboration-oriented strategies. The results reveal that higher perceived luxury from investment-oriented strategies increases CV and WTP, particularly among leisure consumers with lower environmental concern (EC). The findings emphasize the importance for luxury hotel managers to focus on credible, high-cost sustainability initiatives to boost CV and WTP, while also considering varying levels of EC among their clientele. This research bridges the gap between sustainability and recreational luxury, offering practical insights for improving consumer perceptions and driving premium pricing strategies.

Earthquake is a fierce and unavoidable natural disaster. The study of aftershocks following an earthquake provides a comprehensive understanding of seismic activity, making it an important area of research. Although it is important to mention that the use of the Poisson distributed population, to estimate the mass mean of rare events such as earthquakes, has been little studied in the literature. In this context, this study proposes a new class of logarithmic type ratio estimators for estimating the mean of a Poisson distributed population in a simple random sampling without replacement. The proposed estimators are obtained using the logarithmic transformation of the ratio estimator, and the expressions for the mean square error (MSE) are also derived to the first order of approximation. The study demonstrates that the proposed logarithmic type estimators are more efficient than the existing estimators, both theoretically and empirically. The Empirical evidence from a real data study conducted using earthquake data from Turkey confirms the superiority of the proposed estimators over the existing estimators. The study provides valuable insights for researchers and practitioners working with Poisson distributed populations and requiring ratio estimators using simple random sampling without replacement.

Purpose - Popularity of organic food and food products is growing across the globe due to rising awareness towards health and environment, leading to quality life. However, the multitude of challenges associated with the purchase and consumption of organic food remain insufficiently addressed within the context of developing nations, such as India. This study attempts to fill this gap by identifying the crucial barriers and analyzing them further to establish contextual relationships among them. Design/methodology/approach - In total, 18 barriers identified with a literature review are classified into 6 major barriers (constructs) using exploratory factor analysis (EFA). Further, fuzzy decision-making trial and evaluation laboratory (DEMATEL) approach is employed to relegate these barriers and sub-barriers into the cause-and-effect group. Moreover, causal relationships among these barriers are also established to assist organic food producers and food processing industries in developing the strategies to overcome these barriers. Findings - The study results indicate that acceptability, preferability and reachability are the most prominent barriers. Moreover, reachability' is the leading cause group barrier, while acceptability is the major effect group barrier. Usualness, visibility and readiness of the organic food exhibit significant challenges in the organic food consumption. Practical implications - The findings of this study act as a roadmap and guiding principle for various stakeholders, such as organic food manufacturers, organic food processing industries, government policymaking bodies and food certification agencies, in organizations and government regulatory agencies for devising and implementing targeted strategies to enhance the accessibility, appeal and, in turn, adoption and consumption of organic foods. This successively contributes to broader efforts in improving public health and ensuring sustainable agricultural practices. Originality/value - The contribution of this study is two-fold. First, it investigates the interdependences among the organic food consumption barriers. Second, it provides policy-related recommendations to enhance the consumption of organic food, especially in India.
