Generalization of the immigration and the stable population model

Building upon an idea presented by Espenshade, Bouvier and Arthur (1982) about the eventual stationarity of a population subjected to a net reproduction rate of less than one and a constant stream of immigration, this note reports the consequences upon the birth trajectory for all possible values of the net reproduction rate. It has been shown that when the net reproduction rate is equal to one, the number of births increases linearly with time. As may be expected, the increase is exponential for values of net reproduction rate greater than one.     

Sacrificing Women: A Study of Ritualized Practices among Women Volunteers in India

This study addresses issues related to inequality formation and reproduction, especially in regard to gender dynamics operating in a non-western society. Grounded in a post-colonial understanding of urban educated upper and middle class women NGO volunteers in contemporary India, it analyzes how they negotiate new approaches to challenge existing traditional gender roles, yet in critical ways contribute to their reproduction, particularly the traditional concept of ideal Indian womanhood. Employing structural ritualization theory we examine how ritualized symbolic practices related to the traditional concepts of caretaking, sacrifice, and the concept of natural sexual differences continue to be emphasized in a generation confronted with conflicting expectations about modern women’s roles. Twenty-one testimonies provide the major source of evidence along with data gathered through participant observation. This research enhances our understanding of the power of rituals and how they can continue to shape the cognitions and activities of actors.

Framing the corporate responsibility-reputation linkage: The case of Tata Motors in India

This study, focusing on the emerging economy context of one of India's largest automotive companies, Tata Motors, analyzes the thematic framing of corporate social responsibility (CSR) and corporate reputation. Five CSR frames are shown: institutionalization, community development, modernization, mainstreaming, and nation-building. Reputation is framed via: heritage, nationbuilding, technological advancement, global footprint, and responsibility. The findings suggest how firms may better align their CSR efforts with regular business, and their larger public relations campaigns with wider social perceptions of their responsibilities.

Robustness of tests for directional mean

In this paper we study the robustness of the likelihood ratio, circular mean and circular trimmed mean test functionals in the context of tests of hypotheses regarding the mean direction of circular normal and wrapped normal distributions. We compute the level and power breakdown properties of the three test functionals and compare them. We find that the circular trimmed mean test functional has the best robustness properties for both the above-mentioned distributions. The level and power properties of the test statistics corresponding to these functionals are also studied. Two examples with real data are given for illustration. We also consider the problem of testing the mean direction of the von-Mises–Fisher distribution on the unit sphere and explore the robustness properties of the spherical mean direction and likelihood ratio test functionals.     

Towards a Multidimensional Measure of Governance

This paper proposes a new index of governance based on the Alkire-Foster methodology and compares it with the Mo Ibrahim Index of African Governance. The proposed new index improves on existing measures of governance in two ways. First, it is able to incorporate both cardinal and ordinal variables without having to assign cardinal meaning to ordinal variables. The cardinalization of ordinal variables can lead to ambiguous rankings depending on the choice of the cardinal scale. Second, by borrowing the mechanism of cutoffs found in poverty measurement literature, the index can focus attention on nations deprived in terms of governance. The index is computed for the 48 countries of the Mo Ibrahim Foundation’s data. The groups of best-performing and worst-performing nations identified by each of the two methods are largely similar. However, there are some differences among the middle order governance nations. An additional advantage of the proposed methodology is that it involves counting each country’s achievements in the dimensions of governance, which can be presented in a report card of governance.     

Estimation of population mean in presence of random non response in two-stage cluster sampling

The present investigation addresses the problem of estimating a finite population mean in two-phase cluster sampling in presence of random non response situations. Utilizing information on an auxiliary variable, regression type estimators has been proposed. Effective imputation techniques have been suggested to deal with the random non response situations. The properties of the proposed estimation strategies have been studied for different cases of random non response situations in practical surveys. The superiority of the suggested methodology over the natural sample mean estimator of population mean has been established through empirical studies carried over the data sets of natural population and artificially generated population.
