Convoy movement problem (CMP) is an important optimisation problem, especially occurring in military logistics, which focuses on routing convoys concurrently in a network. The CMP is subject to constraints for preventing certain interactions between convoys such that the objectives related to travel times of them are minimised. We propose a Lagrangian relaxation (LR) approach to efficiently obtain a lower bound on the optimal solution. Our LR approach does not have integrality property, and hence the lower bound obtained is always tigher than the lower bound obtained using the LP relaxation. As CMP is an NP-complete problem, lower bounds are useful to evaluate the solutions obtained by a heuristic. From our computational experimentation, it is found that the proposed LR approach is superior to the existing LR approach. © 2020 Inderscience Enterprises Ltd.

A Lagrangian-relaxation-based bounding approach for the convoy movement problem in military logistics

This study investigates the sources of liquidity commonality in an emerging Asian market. Specifically, the demand side and supply side factors were tested in an order-driven Indian stock market. The results indicate that growth in the industrial production and bank credit reflecting the supply side variables are found to have significant influence on liquidity commonality. However, compare to the supply side, demand side factors reflecting the trading behaviour of domestic and foreign institutional investors exhibited higher influence. Study has further extended the literature by investigating the size and sectorial effects and found heterogeneous impact on commonality. © 2020 Informa UK Limited, trading as Taylor & Francis Group.

Primary Caregivers are the fulcrum in the physician-caregiver-child triad. Existing literature discusses static multi-component interventions in detail. In long-term treatments, dynamic intervention design is needed as the environment and situations of the families are dynamic. The objectives of this study are (a) to identify the components of the primary caregiver’s perception of the physician’s value with reference to the effectiveness of consultation and relationships with the former and with the child; (b) to establish the role of this perception in designing dynamic interventions, and (c) to describe the perception’s potential influence on adherence. A PRISMA, chronological, and morphological analysis of the literature is carried out about caregivers’ adherence in the pediatric long-term treatment context. We define communication and consultation as the functional, whereas relationship as the emotional component of the caregiver’s perception of the physician. We propose a theoretical model that incorporates intervention as an integral component of care. Adherence happens as a response to changing situations and hence fluctuates. Hence, a dynamic intervention design to benefit the child should be incorporated into care through the caregiver-physician bridge. Future research should explore how intervention needs change and the driving reasons for understanding the static and dynamic components of interventions. © 2020 Taylor &amp; Francis Group, LLC.

In recent days, both collaboration and sustainability have become an integral part of many global supply chains to achieve business excellence. Although previous literature and actual practices confirmed the successful implementation of sustainability practices through supply chain collaborations, it is not clear how collaborating partners can support financial and environmental performance, and hence strengthen the partnership performance in the global supply chains. To address this practice-based research question, we test the theoretical underpinning of suppliers and logistics partners in relation to required skills selection. We capture the depth of interdependencies in collaborations for routine operations and sustainability, through empirical evidence. We used case study observations from three global companies to develop a conceptual model and also conducted a questionnaire survey to test the conceptual model. The results of case analysis confirmed two dimensions of collaborations that could strengthen relationship; namely, partners’ selection and sustainability team formation. Data analysis strongly support business collaborations having careful choice of supply chain partners and logistics operators who are ready to maintain green operations with transparent information sharing. Results of this study also inform managers about the importance of commitment from collaborating partners to achieve sustainability in their global supply chains. It is clear from the results that both the business and financial performances will be strengthened by environmental positioning (green objectives) of the companies. © 2020 Informa UK Limited, trading as Taylor & Francis Group.

How selection of collaborating partners impact on the green performance of global businesses? An empirical study of green sustainability

Purpose This study aims to review the extant literature on workplace disability inclusion in the organised sector in India and presents an integrated model based on emergent themes in indigenous studies.Design/methodology/approach The review is directed by the following foci: In what contexts was workplace disability inclusion in India empirically investigated? How was workplace disability inclusion examined (method)? What important themes emerge from the studies? Towards this, empirical scholarly studies in India, published between 2011–2019, is reviewed to identify the evolutionary trends.Findings Prominent themes have been identified at three levels – organization, group and individual. At an organization level, the focus is on inclusive strategy and practices. Country-specific contextual factors such as legislation, accessibility and external eco-system influence an organization’s inclusive strategy, which addresses how organizations engage with persons with disability (PwD), job mapping, accessibility and targeted recruitment. Inclusive practices span across various phases of the employee life cycle, namely, recruitment, onboarding, development and retention. At the group level, the themes highlight group boundaries, PwD-supervisor interaction, PwD-co-worker interaction and PwD-PwD interaction. At an individual level, PwD experiences are categorized as physical, job-related and psychological. Workplace treatment and experiences of PwD vary from discrimination to inclusion and along with other outcomes, are influenced by contextual factors.Research limitations/implications This study contributes to the development of workplace disability inclusion theory, by presenting an integrated model of prominent themes, offering greater clarity and avenues for extending the literature. The paper discusses themes that can help organizations facilitate inclusion, thereby improving employment opportunities for PwD.Originality/value In a first, the study provides an integrated account of inclusion of PwD in organized sector in India.

Workplace disability inclusion in India: review and directions

In this article, we investigate patterns in returns, volume and volatility and analyse the volume–return relationship using tick-by-tick data from the Indian equity market. Based on descriptive measures and regression frameworks, we document three important findings. First, we report unusually high volatility, trading volume and number of trades during the opening and closing minutes of the market depicting a ‘U’-shaped curve, implying high market activity during these periods. Second, while accounting for trading volume, we observe that volatility is not significantly different between mid-day period and evening period as compared to the normal ‘U’ curve. Finally, we document a significant positive relationship between intraday volume and price movements controlling for microstructure effects. The impact of positive returns on trading volume is higher than the impact of negative returns, implying the presence of return–volume asymmetry in the Indian market.

Purpose Despite increased attention towards workplace disability in global and local development agenda, mainstream inclusion of persons with disability continues to be a challenge for most organizations. This paper aims to explore how organizations can be facilitated for adapting to the need and responsibility for change, towards evolving into disability inclusive workplaces.Design/methodology/approach This paper uses an inter-domain approach by linking organization change and development models to Indian indigenous disability management literature.Findings This review indicates that in comparison with the other dimensions of diversity, disability brings unique challenges that need a differentiated management approach. Further, it finds a strong base for organizations to approach disability management as a strategic and transformative change initiative, aligning with some of the proven change and organization development (OD) interventions.Research limitations/implications This paper draws implications for disability management and highlights the need for a practice perspective towards disability management and OD.Originality/value This paper provides an integrated view of critical factors influencing workplace disability management and OD.

Towards a confluence: disability inclusion and organizational change

With the arrival of Internet of Things, the magnitude of data shared through various devices has seen a drastic increase. Fitness trackers contribute to a significant part of this phenomenon. Increase in collection of individual's information has led to increase in privacy issues like identity theft and targeted marketing. This study treats information privacy as a distinct dimension and develops a model, drawing from extant privacy concern literature, Extended Parallel Process Model and coping theory to understand an individual's coping behavior when faced with a privacy breach to their user generated health data. The model is empirically tested by conducting a sample survey with 225 fitness tracker users. Our findings show that increased privacy concern increases threat perceptions, which has a major impact on an individual's coping behavior. The major contribution of this study is towards the understanding of the impact of fear over loss of one's health-data privacy and the resulting shift in the attitude towards the technology itself. Theoretically this study extends fear appeals theory to information privacy by incorporating the role of individual's privacy concern. This study implies that manufacturers and policy makers in healthcare domain need to re-examine privacy and data processing policies keeping in mind potential consumer privacy concerns.&nbsp;
