Human resource planning as a strategic function: Biases in forecasting judgement

Manjari Singh and Jatinder Kumar Jha

International Journal of Strategic Decision Sciences

This paper explores the strategic importance of human resource (HR) planning and the various techniques employed by organizations to attract talent and thus to gain a competitive edge. In this paper, the authors have tried to explore the various biases that come into play when supervisors forecast for human resources. Backed by research, the paper recommends the integration of line managers with HR managers and their participations in strategic planning to enable the HR managers to gain valuable insights for HR planning. The paper further suggests that though biases cannot be ruled out completely but they can be controlled by providing relevant training to the HR and line managers to forecast dynamics. Further, the judgement of the line managers could be complemented with other forecasting techniques to make the process more reliable.

Rough information set and its applications in decision making

Manish Aggarwal

IEEE Transactions on Fuzzy Systems

The decision making in the real world is inevitably characterized with vagueness, and imprecision due to incomplete knowledge. To this end, we combine the information set with the rough set theory to represent both the vagueness and imprecision at the same time. We term the proposed structure as rough information set that has information sets based on fuzzy equivalence relations as its building blocks. The usefulness of the proposed structure is demonstrated through a case study in credit scoring analysis, and a biometrics application on knuckle-based recognition.

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.

Replicating small farms, prosperous farmers in India: Lessons for policy and practice

Sukhpal Singh

Journal of Agribusiness Marketing

Small farm and small farmer viability has been a constant policy concern in India given its smallholder-dominated agriculture. Though there are different definitions of small farm in the literature, depending on local context, the term “smallholder” is a relative one in that it refers to the limited resource endowments of such farmers relative to those of other farmers in the sector in each local context. The Indian small farmers are in a state of agrarian distress, and the farmers’ quest for earning enough from a small farm continues. It is in this context of academic and policy discourse that this article makes evidence-based policy and practical recommendations for replicating the Small Farmer, Prosperous Farmer (SFPF) models of agricultural development in India based on empirical case studies of 35 small (who were just 2 hectares or smaller farm operators) and prosperous farmers (earning at least one lakh (0.1 million)Indian rupees per acre per year) across three states of India— Punjab, Gujarat, and Maharashtra. Major objectives of the study carried out in 2012 were as follows: document profiles of SFPFs in terms of their resources, costs, and profits; provide evidence of success (in terms of net income and prosperity) given small holdings; identify major factors in prosperity/success—personal, institutional, and social; and understand the role of policy and business environment, if any; and infer on possibilities of replicability of SFPF success given the other contextual factors in other regions. The study identifies sources of success and policy relevance of such factors for making inclusive agricultural development possible.

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.

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.

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.

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.
