Adaptive linguistic weighted aggregation operators in multi-criteria decision making

Manish Aggarwal

Applied Soft Computing

In this paper, we propose new aggregation operators for multi-criteria decision making under linguistic settings. The proposed operators are based on two sets of criteria weights. Besides the primary conventional criteria weights, we introduce a method to deduce secondary criteria weights from the criteria evaluations, which reflect the role of the different criteria in discriminating among the alternatives. The properties of the proposed operators are investigated. An approach for the application of the said operators in a group multi-criteria decision making problem is presented. Following the same, the proposed operators are applied in a case study on supplier selection. The empirical validation of the proposed operators is performed on a set of 12 real datasets.

Negotiating absent practices and dormant features: discourse as a means of shaping the implementation of a global enterprise system to meet local work culture

George Kandathil and Erica L. Wagner

2017 CHI Conference

The introduction of a new enterprise system to an organization often necessitates the accommodation of standardized practices, which may be in conflict with local users' practices and their work culture. We explore such a conflict in an India-based multinational organization using an eight-month interpretive case study. Based on grounded analysis, we present a narrative account of how consultants, on contract for managing the deployment and making necessary adjustments, used discourse as a means of shaping user understanding about the features and practices embedded in the underlying system, which were not initially realized through the interface. Sustained user resistance to this shaping led to a negotiated compromise and adaptation of the system to incorporate local work culture. Our findings allow us to explore the under-theorized role of discursive power within an implementer-user-technology trio, and illustrate the feedback utility of user resistance in developing culturally-inclusive designs.

Normative underpinnings of direct employee participation studies and implications for developing ethical reflexivity: A multidisciplinary review

George Kandathil and Jerome Joseph

Journal of Business Ethics

This paper seeks to join studies which have drawn attention to the ethical reflexivity of research and the research enterprise in the organisational studies’ field. Towards this end, we review OB, HRM, and IR studies on direct employee participation in organisations post-1990s to examine their normative underpinnings. Using Fox’s (Industrial sociology and industrial relations. Research Paper 3, Royal Commission on Trade Unions and Employers’ Associations, HMSO, London, 1966, Beyond contract: Work, power and trust relations. Faber and Faber, London, 1974) three frames—unitarist, pluralist, and radical—we compare the underpinnings within and across the chosen disciplines to bring ethical reflexivity to studies in this area of inquiry. Implications are drawn out to take forward the quest for more ethically reflexive employee participation research.

Emergence of distributed coordination in Kolkata Paise Restaurant problem with finite information

Diptesh Ghosh and Anindya S. Chakrabarti

Physica: Statistical Mechanics and its Applications

In this paper, we study a large-scale distributed coordination problem and propose efficient adaptive strategies to solve the problem. The basic problem is to allocate finite number of resources to individual agents in the absence of a central planner such that there is as little congestion as possible and the fraction of unutilized resources is reduced as far as possible. In the absence of a central planner and global information, agents can employ adaptive strategies that uses only a finite knowledge about the competitors. In this paper, we show that a combination of finite information sets and reinforcement learning can increase the utilization fraction of resources substantially.

Investigating a An evolutionary analysis of growth and fluctuations with negative externalities

Anindya S. Chakrabarti and Ratul Lakhar

Dynamic Games and Applications

We present an evolutionary game theoretic model of growth and fluctuations with negative externalities. Agents in a population choose the level of input. Total output is a function of aggregate input and a productivity parameter. The model, which is equivalent to a tragedy of the commons, constitutes an aggregative potential game with negative externalities. Aggregate input at the Nash equilibrium is inefficiently high causing aggregate payoff to be suboptimally low. Simulations with the logit dynamic reveal that while the aggregate input increases monotonically from an initial low level, aggregate payoff may decline from the corresponding high level. Hence, a positive technology shock causes a rapid initial increase in aggregate payoff, which is unsustainable as agents increase aggregate input to the inefficient equilibrium level. Aggregate payoff, therefore, declines subsequently. A sequence of exogenous shocks, therefore, generates a sustained pattern of growth and fluctuations in aggregate payoff.

Unsustainability of sustainability: Cognitive frames and tensions in Bottom of the Pyramid projects

Garima Sharma and Anand Kumar Jaiswal

Journal of Business Ethics

Existing research posits that decision makers use specific cognitive frames to manage tensions in sustainability. However, we know less about how the cognitive frames of individuals at different levels in organization interact and what these interactions imply for managing sustainability tensions, such as in Bottom of the Pyramid (BOP) projects. To address this omission, we ask do organizational and project leaders differ in their understanding of tensions in a BOP project, and if so, how? We answer this question by drawing on a 5-year study of a BOP project of a global pharmaceutical company in India. In line with the existing research, we found three kinds of frames—paradoxical, business case, and business—held differently across organizational levels and over time. We also found that the shift in frames of both project and organizational leaders was mediated by the decision-making horizon. The initial divergence across organizational levels, seen in paradoxical and business frames, was mediated by long-term decision-making horizon. However, there was an eventual convergence toward business frames associated with the shift from long- to shorter-term decision-making horizons and one that led to the project’s closure. We contribute by proposing a dynamic model of cognitive frames in sustainability, where the research has either alluded to top-down or bottom-up understanding.

The role of cluster presence and quality certification in internationalization and performance of offshore service providers

Rajesh S. Upadhyayula, Karthik Dhandapani, and Amit Karna

Journal of International Management

Offshore Service Providers (OSPs) have been a subject of research for several years now. However, there is little known about what drives the internationalization of OSPs. In this paper, we combine insights from economic geography and institutional view to investigate cluster presence and quality certification as the drivers of OSP internationalization and their performance. We hypothesize the facilitating role these two factors play in driving the performance of internationalized firms. We test our hypotheses using data from Indian software firms between 1992 and 2002. We find a positive effect of certification on OSP internationalization. Although certification contributes negatively to OSP performance, it positively moderates the performance effect of OSP internationalization. Cluster presence was found to drive OSP's overall performance, but has no effect on internationalization. Through our findings, we contribute towards the literature on OSP internationalization.

Urban common service generation, delivery and management: A Conceptual Framework

Arpit Shah and Amit Garg

Ecological Economics

Urban commons are currently not studied holistically under the rationale used by the ecosystem cascade framework. In this paper, we build on the ecosystem cascade framework to present a conceptual model that provides a comprehensive view of urban common resources and allows decision-makers to develop suitable interventions to meet objectives of sustainability and equity. The model looks at the role of and explains the linkages between urban commons' biophysical structures, user population characteristics, power dynamics, use behavior, benefits generated, and management strategies. The model adds to existing literature by focusing on direct benefits and equity and by elaborating on the role of transaction costs and management strategies in governing urban commons. Considering direct benefits allows for a complete picture of overall benefits while making governance decisions, as opposed to considering benefits received only through human effort. Focusing on power asymmetries between stakeholders highlights the inequities created in accessing benefits from urban commons. Elaborating on management strategies provides greater insight into the complexities of managing urban commons and the impacts that governance decisions can have. Finally, including transaction costs highlights the factors that influence costs of managing resources. We illustrate the use of the model with literature from urban India.

Let the people speak: Improving regional adaptation policy by combining adaptive capacity assessments with vulnerability perceptions of farmers in Gujarat, India

Ryan Stock, Trevor Birkenholtz, and Amit Garg

Climate and Development

Farmers throughout the Global South are vulnerable to extreme heat events and shifting precipitation patterns associated with climate change. This is particularly the case in Gujarat, India, which is experiencing fluctuating monsoon rains and seasons. Local institutions there are ill-equipped to assist farmers in adapting to these changes. However, farmers are adapting to climate change, largely through livelihood diversification, in the absence of formal state intervention. Using qualitative methods, we conducted adaptive capacity assessments and assessed vulnerability perceptions in 3 villages, involving 120 farmers from diverse socioeconomic backgrounds. Combining vulnerability perceptions with adaptive capacity assessments, we better observed the mismatch between rural development policy with the potential to aid in adaptation processes that address local needs, identifying why policy fails to increase the adaptive capacity of the agriculturalists most vulnerable to climate impacts. Decentralizing adaptation programmes to community-level institutions can increase the efficacy of climate interventions by emboldening latent institutions, while not widening the socioeconomic gap of a rapidly modernizing India.
