The Law of Restitution for unjust enrichment in India

M P Ram Mohan and Mridul Godha

Lloyd’s Maritime and Commercial Law Quarterly

The law of restitution for unjust enrichment is among the most debated private law topics today. It has been invoked to justify the right to restitution in cases which fall outside the scope of contract law. Despite being well developed in many common law countries, and a part of this area of law being codified in the Indian Contract Act 1872, ss 68–72, courts in India have applied the principle of restitution for unjust enrichment inconsistently and in conflict with codified law. This paper gives clarity on this position and proposes to fill the academic vacuum in this regard.

An exploration of public risk perception and governmental engagement of nuclear energy in India

M P Ram Mohan and Sreenath K Namboodhiry

Journal of Public Affairs

Public acceptance constitutes an important factor in successfully establishing and operating nuclear power plants. This paper explores public attitudes to the Kudankulam Nuclear Power Project commissioned in 2013 and situated in Southern India, through assessing the role of socio-demographic factors, externalities, and social trust in determining the level of public acceptance. An exploratory survey (n = 100) was carried out in two administrative units in the vicinity of the plant. The study reveals that acceptance of the plant is positively correlated with positive externalities and trust in governmental entities, whereas negative externalities and trust in antinuclear nongovernmental organizations and media are associated with negative public perception. The results show that governmental policies on nuclear power must support the effects of positive externalities and reduce the effects of negative externalities.

Social connections and tertiary health-care utilization

Tarun Jain and Sisir Debnath

Health Economics

The use of tertiary health care by socially proximate peers helps individuals learn about program and treatment procedures, signals that using such care is socially appropriate, and could support the use of formal health care, all of which could increase program utilization. Using complete administrative claims data from a publicly financed tertiary care program in India, we estimate that the elasticity of first-time claims with respect to claims by members of caste groups within the village is 0.046, with smaller effects of more socially distant individuals. The point elasticity of inpatient care expenditure with respect to claims filed by the same group in village peers in the previous quarter is Image removed.0.035. We find support for an information channel as peers increase awareness of the program and its features. Our findings have implications for the development of network-based models to determine health-care demand, as well as in use of network-based targeting to boost tertiary health-care utilization.

A constrained agglomerative clustering approach for unipartite and bipartite networks with application to credit networks

Samrat Gupta and Pradeep Kumar

Information Sciences

Researchers and practitioners have been interested in solving real-world problems through clustering. The clustering of nodes in networks with unipartite or bipartite structure is important to explore real-world complex networks present in nature and society. Bipartite networks form an important class of complex networks because they reveal the heterogeneity of nodes in a network. However, most extant clustering methods focus only on unipartite networks. In this work, a novel constrained agglomerative clustering method applicable to unipartite and bipartite networks has been proposed. Initially, the topology of a network is modeled according to set-theoretic principles. Subsequently, the concepts related to rough set theory and relative linkage are used to cluster the set of nodes. The utility and effectiveness of the proposed approach are demonstrated through offline experiments on unipartite and bipartite networks. A comparison against ten state-of-the-art similarity measures over two different partitional clustering algorithms reveals the effectiveness of the proposed relative linkage measure. Moreover, a comparative analysis with state-of-the-art network clustering methods reveals the viability of the proposed rough set-based constrained agglomerative clustering algorithm. Finally, the proposed method has been applied for the detection of cohesive subgroups of banks in a real bipartite network formed by mapping credit relationships between Indian firms and banks.

Geographical dissimilarity and team member influence: Do emotions experienced in the initial team meeting matter

Vishal Gupta, Prithviraj Chattopadhyay, and Elizabeth George

Academy of Management Journal

It is both important and challenging to gain influence within geographically diverse teams. We argue that the emotions team members experience in their initial team meetings moderate the effect of geographical dissimilarity on their perceived influence on team decisions over time. Specifically, we contrast social identity theory–based arguments that geographical dissimilarity negatively influences perceived influence with self-categorization theory–based arguments that there is a positive relationship between geographical dissimilarity and perceived influence. We argue that the emotions team members experience in their initial meeting determine which of these relationships eventuate over time. Across two studies, our data support our arguments. We find that for individuals experiencing pleasant high-activation emotions, their geographic dissimilarity was more positively related with perceived influence in the initial stage of a project; for those experiencing unpleasant low-activation emotions, their geographic dissimilarity was positively related with perceived influence in the later stage; for those experiencing unpleasant high-activation emotions, their geographic dissimilarity was initially positively and later negatively related with perceived influence.

Engagement patterns of participants in an online professional development programme: An application of mixture modelling

Ketan S. Deshmukh, Vijaya Sherry Chand, Kathan D. Shukla, and Arnab K. Laha

Proceedings Of The Annual Hawaii International Conference On System Sciences

Unhindered communication capabilities, in the form of internet, led us to believe that the difficult goal of “Education for All” is within our grasps. Recent studies have shown mixed results for learning over the internet, indicating that we are still far away from our desired goal. Online environments provide freedom to large number of learners, to learn at their own pace. Understanding the various ways in which participants engage with online content could help explain the mixed outcomes. This paper presents the results of an exploratory study on engagement patterns of 4567 elementary school teachers, in an online professional development programme. Using mixture modelling techniques, we identified five latent profiles of online engagement and seven latent classes based on off-platform activities. We present our findings followed by discussion and implications for online courses.

Stochastic modeling of parallel process flows in intra-logistics systems: Applications in container terminals and compact storage systems

Govind Lal Kumawat, Debjit Roy, Rene De Koster, and Ivo Adan

European Journal of Operational Research

Many intra-logistics systems, such as automated container terminals, distribution warehouses, and cross-docks, observe parallel process flows, which involve simultaneous (parallel) operations of independent resources while processing a job. When independent resources work simultaneously to process a common job, the effective service requirement of the job is difficult to estimate. For modeling simplicity, researchers tend to assume sequential operations of the resources. In this paper, we propose an efficient modeling approach for parallel process flows using two-phase servers. We develop a closed queuing network model to estimate system performance measures. Existing solution methods can evaluate the performance of closed queuing networks that consist of two-phase servers with exponential service times only. To solve closed queuing networks with general two-phase servers, we propose new solution methods: an approximate mean value analysis and a network aggregation dis-aggregation approach. We derive insights on the accuracy of the solution methods from numerical experiments. Although both solution methods are quite accurate in estimating performance measures, the network aggregation dis-aggregation approach consistently performs best. We illustrate the proposed modeling approach for two intra-logistic systems: a container terminal with automated guided vehicles and a shuttle-based compact storage system. Results show that approximating the simultaneous operations as sequential operations underestimates the container terminal throughput on average by 28% and at maximum up to 47%. Similarly, considering sequential operations of the resources in the compact storage system results in an underestimation of the throughput capacity up to 9%.

Performance Behavior of participatory water institutions in Eastern India: A study through structural equation modelling

Nicky Johnson, Vasant P. Gandhi, and Dinesh Jain

Water (Switzerland)

The paper examines the nature and performance of participatory water institutions in eastern India using structural equation modelling. There is a crisis in the management of water in India, and this is often not about having too little water but about managing it poorly. It is now being widely recognized that engineering structures and solutions are not enough, and having effective water institutions is critical. These are urgently needed in eastern India for helping lift the region out of low incomes and poverty. However, creating good institutions is complex, and in this context, the fundamentals of new institutional economics, and management governance theory have suggested the importance of a number of key factors including five institutional features and eight rationalities. Based on this, a study was conducted in eastern India, sampling from the states of Assam and Bihar, covering 510 farm households across 51 water institutions. In order to understand and map the relationship and pathways across these key factors, a structural equation model is hypothesized. In the model, the five institutional features are considered determinants of the eight rationalities, and the rationalities are considered determinants of four performance goals. The performance on the goals determines the overall performance/success of the institution. Besides this, the institutional features and rationalities can also directly influence performance on the goals and the overall performance. The model is tested with data from the survey and different pathways that are robust are identified. The results can provide useful insights into the interlinkages and pathways of institutional behavior and can help policy and institution design for delivering more robust performance. The results show that one of the most important factors determining overall performance/success is technical rationality, and this deserves great attention. It includes technical expertise, sound location and quality of structures and equipment, and good maintenance. However, success is also strongly linked to performance on production/income goals, equity, and environment goals. These are, in turn, strongly related to achievement of economic, social, technical, and organizational rationalities, which call for attention to economic aspects such as crop choice and marketing, besides social aspects such as inclusion of women and poorer social groups, and organizational aspects such as member involvement and regular meetings. Further, the institutional features of clear objectives, good interactions, adaptive, correct scale, and compliance are important for achievement of almost all rationalities through various pathways, and should be strongly focused on in all the institutions.

Gender perspective in water management: The involvement of women in participatory water institutions of Eastern India

Varsha Khandker, Vasant P. Gandhi, and Nicky Johnson

Water (Switzerland)

The paper examines the extent, nature, and factors affecting women’s involvement in participatory irrigation institutions of eastern India. Effective participatory water institutions are urgently needed to improve water management in eastern India, and a significant aspect of this is the involvement of women. There is inadequate representation, participation, and involvement of women in most water institutions. From the participatory and social point of view, this is a significant concern. The relevant data are obtained from the states of Assam and Bihar through a focused survey administered to 109 women in 30 water institutions, and a larger farmer-institutional survey covering 510 households and 51 water institutions. The research examines the extent and nature of the involvement of women in these institutions, as well as in farm decision-making, and the factors that prevent or foster their participation. Additionally, it examines the gender congruence in views regarding water institution activities and their performance, and the perceived benefits of formal involvement of women. The results show that their inclusion is very low (except required inclusion in Bihar), and the concerns of women are usually not being taken into account. Women are involved in farming and water management decisions jointly with men but not independently. Findings indicate that the views of women and men differ on many aspects, and so their inclusion is important. Responses indicate that if women participate formally in water user associations, it would enhance their social and economic standing, achieve greater gender balance, expand their awareness of water management, and contribute to better decision-making in the water institutions.
