Tenancy reforms: A critique of NITI Aayog’s Model Law

Sukhpal Singh

Economic and Political Weekly: A Journal of Current Economics and Political Affairs

There is no doubt that the agricultural land leasing laws in India need to be amended to make land leasing legal and easier. The Niti Aayog report (2016) proposes a formal model law on land leasing. Critically examining the logic for liberalisation of land leasing laws, the limitations of the model lease agreement are brought out. It is argued that the model law ignores the diversity and dynamics of leasing arrangements in India and the socio-economic implications of the realities of tenancy practices.

Case-Optimal Movement Plan of rice in the state of Andhra Pradesh in India

Sundaravalli Narayanaswami and N. Ravichandran

Informs Transactions on Education

The case discusses an optimal movement plan for food grains (rice) by a state sponsored agency, the Food Corporation of India (FCI) in the State of Andhra Pradesh in India. There are five resource locations and eleven demand locations in this distribution network. Resource capacity and demand requirement for the three product (rice) variants at each location are known. There is no storage capacity restriction either in the demand or source location. Information related to rail network, its connectivity, distance in kilometers between origin-destination pairs, cost of transportation per tonne of food grain by rail or road are known. The primary issue is to develop a monthly movement plan to minimize the overall transportation costs subject to meeting the demand-supply restrictions. The total supply available for distribution and the total requirement at various locations are both equal at the product variant and aggregate level. The secondary issue is to develop an alternative movement plan to fulfil the demand requirements at a location, Karimnagar, which does not have a direct rail connection. Few plans are proposed to resolve the issues; the case encourages analysis of the problem situation and evaluation of the alternate resolution plans.

The essence of downsizing: A review of literature

Prantika Ray and Sunil Kumar Maheshwari

The Indian Journal of Industrial Relations

The process of downsizing has often been considered as a onetime activity that is disconnected from the processes and the outcomes associated with the activity. Since the strategies, organizational, industrial and environmental characteristics play a crucial role in determining the success and/or failure of the downsizing process, a piece-meal approach to the research on downsizing is not enough. This paper thus presents a holistic view of the downsizing process where the dynamics that ensue during the downsizing are elucidated in a framework. This paper further discusses certain implications for practitioners and provides scope for future research for the researchers.

Does strategic planning determine innovation in organizations? A study of Indian SME sector

Safal Batra, Sunil Sharma, Mukund M. Dixit, and Neharika Vohra

Australian Journal of Management

While some researchers argue that strategic planning assists new product development and can be viewed as a framework for innovation, others believe that it restricts creativity and innovation. Despite a literary appreciation that strategic planning is linked to innovation, the nature of this relationship remains ambiguous. In this study, we argue that this relationship is context dependent and contingent on other organizational factors. Data for this study were collected by administering standardized survey questionnaires to entrepreneurs or other senior executives of small and medium businesses in India. Quantitative analysis of data obtained from 162 small- and medium-sized enterprises (SMEs) in the manufacturing sector reveals a positive relationship between strategic planning and innovation. This study also establishes a significant positive moderating role of commitment to learning on the relationship between strategic planning and innovation. Implications for theory and practice are discussed.

Two-stage test of means of unordered pairs

Tathagata Banerjee Gaurangadeb Chattopadhyay and Kaustav Banerjee

Statistics in Medicine

The problem of testing equality of means of a bivariate normal distribution on the basis of a sample of size n has been considered when the labels of the observations are either missing or not known. The problem may arise in many applied settings, especially in genetics. Classical likelihood ratio test fails here because of identifiability problems. We propose a two-stage testing procedure using a recently developed test in the context of penalized splines. The proposed testing procedure is found to outperform the tests proposed in the literature. Copyright © 2017 John Wiley & Sons, Ltd.

Measurement error in astronomy

Tathagata Banerjee and Surupa Roy

Wiley Stats Ref: Statistics Reference Online

Measurement error is ubiquitous in astronomy. In the astronomical literature, discussion on measurement error problems is almost entirely confined to linear regression. We introduce a linear regression measurement error model (LRMM) highlighting the distinguishing features of the model and the data that typically arise in astronomy. Standard methods, proposed in the statistics literature for tackling measurement error problems in regression analysis, are not useful for the analysis of astronomical data. We briefly discuss the methods, and their appropriateness, commonly used by the astronomers for analysis of data using LRMM. A short discussion, on their relative performances based on the available numerical studies, is given. We conclude with some remarks on data characteristics typical to astronomical data and on an emerging measurement error problem in astronomy.

Effects of non-conformity on perceived status and competence: Examining the moderating role of physical attractiveness

Biswajida Parida and Vishal Gupta

Psychological Studies

The present study attempts to examine how people perceive non-conforming behaviour and what do they infer about subjects who demonstrate non-conformity. Interviews were conducted to determine the operational definition and perception about non-conformity. Analysis of the interviews revealed that non-conformity is attributed to not abiding by the rules that have been defined or laid out by an authority in a particular context. Scenario-based experiments were conducted, and the obtained data were analysed to reach a conclusion regarding observers’ perception about non-conforming individuals in a collectivist culture. The results showed that non-conforming behaviour leads to a negative inference about status and competence. Also, we found that the attractiveness of non-conforming individuals does not lessen the negative inferences derived by the observers in a collectivist culture. The findings can be extended to devise several communication and signalling strategies to influence the mass behaviour in a collectivist culture, like India. The study provides us insights about achieving social objectives as well as driving behavioural change in a collectivist context.

The relationships between leadership, work engagement and employee innovative performance: empirical evidence from the Indian R&D context

Vishal Gupta, Shailendra Singh, and Abhijit Bhattacharya

International Journal of Innovation Management

Integrating the behavioural theory of leadership with job demands–resources theory of engagement, the present study examines the process through which leadership impact R&D professionals’ innovative work behaviours and innovative performance (measured through peer-reviewed journal papers, patents, PhDs guided and keynote addresses delivered). Data from 467 scientists working in India’s largest civilian R&D organisation were collected and analysed using structural equation modelling. The study found that work engagement was positively related to innovative work behaviours as well as innovative performance. Leader behaviours had significant indirect effects on innovative work behaviours as well as innovative performance via work engagement. While the total effect of leadership on innovative work behaviours, the total effect was non-significant for innovative performance. Implications for theory and practice are discussed.
