When Boards Matter: The Case of Corporate Social Irresponsibility

While academic research has made remarkable progress in understanding corporate social responsibility (CSR), we have scant understanding of corporate social irresponsibility (CSiR). This paper adopts a stakeholder‐agency perspective towards CSiR to ask two related questions: (1) What board‐level structures can monitor management to reduce CSiR? and (2) What are the conditions that render board monitoring more effective? Employing a unique objective measure of CSiR and a sophisticated system generalized method of moments with dynamic panel model on a sample of publicly listed firms in the USA between 2002 and 2015, this paper demonstrates how firms with a specific board‐level governance bundle (i.e. a large, more independent board, with a board CSR committee, a higher proportion of women within boards with frequent director activity) are better equipped to reduce irresponsible behaviours, both in terms of number of irresponsible incidents as well as in terms of their economic costs to the firm. Moreover, the effectiveness of this governance bundle sustains under conditions of high institutional ownership and high board remuneration. This paper has implications for CSR and corporate governance literatures, as well as for managers and policymakers.     

Tests for bivariate mean residual life

In this paper we have developed tests for bivariate exponentiaIity against the ‘bivariate decreasing mean residual life (BDMRL)’ and ‘bivariate new better than used in expectation (BNBUE)’ classes of non-exponentia1 probability distributions. We have also obtained a large-sample approximation to make the test readily applicable.     

A mathematical model of a population genetics: Effects of genetic variation on homosexuality

This study deals with simple mathematical models for the purpose of generating testable prediction in genetics. The genetic effects in human population are because of the following four factors, (i) paternal, (ii) maternal, (iii) environmental and (iv) idiopathic. For the measurement of genetic characteristics, the environment also plays an important role. In the present paper we analyze this linkage for homosexuality for the first three factors because the fourth one affects a very little population. This study provides genetics and evolutionary basis for making generating testable predictions specifically where the environmental factors affect the characteristics of genes which also influence homosexuality. The effect of environment on homosexuality is highlighted because earlier studies confined only up to the paternal and maternal linkages. We consider two types of selections (i) direct selection with environmental effects (ii) combined selection with direct, maternal and environmental effects. The objective of this investigation is to provide the conditions for the maintenance of genetic variation of genotype of male and female. We concentrate on highlighting homosexuality as a result of variation in genes. Numerical results are obtained by taking illustration. The sensitivity analysis is carried out to explore homosexuality in terms of fitness loss and fitness gain.     

Single process plan scheduling with genetic algorithms

AIn this paper, a genetic algorithm model for scheduling manufacturing resources is developed for the case when there is only one process plan available per job, hence there is no routeing flexibility. The scheduling objectives considered are minimizing the makespan and mean flow time. Genetic algorithms design issues are discussed and the working of the employed genetic operators is explained in detail. Parameters for the genetic algorithms used for single process plan scheduling SPPS problems are set through extensive experimentation. Finally, the genetic algorithms approach is compared with several other approaches in terms of optimality of solution and computAuthors: ing time. It was observed that in most cases the genetic algorithms approach performed better than other approaches both in terms of finding an optimal or near optimal solution as well as computing time.     

Mortality in Ghana: Evidence from the cape coast project data

This paper deals with the estimation of mortality for a rural community of about 20,000 persons in the rain-forest area of south-west Ghana. Specifically, infant, child and adult mortality estimates have been obtained by the application of a wide range of direct and indirect methods of measuring mortality from the different statistics collected by a longitudinal mortality and fertility project conducted during 1974–7. It was noted that infant and childhood mortality rates obtained from death registrations were consistent with those rates yielded by pregnancy histories and child survival statistics. However, the adult mortality estimates derived from orphanhood statistics tended to be lower than those suggested by death registrations. The analysis revealed an infant mortality rate of 100 for boys and 84 for girls, equal childhood mortality rates for boys and girls (85–6), a lower expectation of life at birth for men (45.8 years) than for women (52.8), and a much more severe incidence of mortality among men aged over 40 than for women at the corresponding ages.     

Transnational ties and ethnic identities in the parental homeland: second-generation Indian Americans in India

ABSTRACT

This article explores the ‘return’ migration of high-skilled, second-generation Indian-Americans from the United States to India. Based on interviews with fifty-six respondents, it asks: What transnational ties do second-generation Indian Americans maintain with India prior to return? Upon return, what are their ‘reverse’ transnational linkages to the United States? How do these linkages shape their ethnic identities, if at all? Findings suggest that respondents’ transnational ties to India prior to return reinforce their identities as Indian Americans. Once in India, they maintain affective and civic ties to the United States, the country where they were born or raised. Further, American-inflected social ideas and norms shape returnees’ interactions with domestic workers in India. As they grapple with the disparities between Western and Indian norms on the treatment of domestic help, respondents privilege ‘American’ identities. These findings highlight the transnational ties and identity construction and negotiation of second-generation returnees.     

Infant and child mortality in India: trends in inequalities across economic groups

This paper examines the trends in economic inequalities with respect to infant and child mortality in India using three rounds of the Indian National Family Health Survey conducted in 1992–1993, 1998–1999, and 2005–2006. The paper uses concentration index, and pooled discrete-time survival regression model to examine the aforementioned trends and regional patterns. The findings suggest a decreasing trend in economic inequality in infant mortality but an upward trend in economic inequality in child mortality in India. Economic inequalities in infant mortality have narrowed in the southern region, whereas they have widened in the western region and risen in the northern region. However, mixed trends in concentration indices were found in the different regions of India in the case of child mortality.     

Determinants of Regional Variations in Infant Mortality in Rural India

An analytical framework is specified for understanding the determinants of infant mortality. It distinguishes between factors at three levels – village, household and individual – and arranges them in ascending order with respect to their proximity to infant mortality. Village and household-level factors are assumed to influence infant mortality indirectly by influencing at least one of the six individual-level factors. The present analysis of the data aggregated at the state level clearly demonstrates the importance of both medical and non-medical factors for explaining the observed regional differences in infant mortality in rural India. The percentage of births attended by trained medical personnel and poverty, are the two important determinants of regional variations in neo-natal mortality; and the village-level availability of medical facilities and the extent of triple vaccination are the two important determinants of post-neo-natal mortality. The influence of adult women's literacy on infant mortality is explained by better medical care at birth, and preventive and curative medical care during the post-neo-natal period. Medical factors have been shown to be slightly more important than non-medical factors. This suggests that it might be possible to reduce the high level of infant mortality currently prevalent in many states in India by simple preventive medical interventions.     

Developing an understanding of lean thinking in process industries

The research described in this article has set out to determine the extent to which lean thinking is being adopted as a manufacturing philosophy by process industries. It concerns the application and examination of key lean manufacturing principles, namely, the alignment of production with demand, the elimination of waste, the integration of suppliers (IS) and the creative involvement of the workforce in improvement activities, to a range of process industry types based on Dennis and Meredith's taxonomy of process industry transformation systems [Dennis, D. and Meredith, J., 2000a. An empirical analysis of process industry transformation systems. Management Science, 46 (8), 1085–1099]. Seventy-nine process industry product streams across 62 sites were studied. In addition, a five-site investigative field study was also undertaken. The findings demonstrate that lean practices associated with the elimination of waste are consistently used for improving manufacturing performance throughout the taxonomy of process industries but practices associated with other lean principles are inconsistently applied. In addition, explanations are provided on the appropriateness of lean thinking as a manufacturing philosophy and a strategy for improving manufacturing performance in different process industry types, and on the extent to which lean principles and practices are dependent on the characteristics of process industry transformation systems.
