Women’s Employment, Well-being, and Safety in SEZs
Special Economic Zones (SEZs) are often seen as drivers of economic growth, yet their impact on workers, particularly women, remains uneven. This study examines women's employment conditions in Sri City SEZ, exploring their implications for empowerment and well-being. Using a mixed-methods approach, we conducted a structured quantitative survey alongside qualitative interviews to capture nuanced experiences. The survey, covering 434 women from An…
A Comparison of Thermal Comfort of Old Indigenous Houses with New Residential Buildings of Kolkata, India
Earth has experienced a global warming of 1.09 degree C over the last two decades when compared to the previous century.This problem has become multifold in the urban areas, thus generating the new phenomenon of "urban warming" as quoted by the IPCC.According to the IPCC data sheet of 2018, the city of Kolkata remains at the top of this urban warming list (2.6 degree C).Majority of this urban warming is contributed by buildings.The residential bu…
Links across disabilities
There are consistent positive associations in the experience of functional difficulties in various domains in the six countries under study. Such correlations may reflect barriers to social services including healthcare services and resources (e.g. assistive devices) that may lead to an avoidable deterioration of functioning across domains. Further research is needed on the trajectories of functional difficulties and on structural barriers that p…
Associations Between Religious/Spiritual Practices and Well-Being in Indian Elderly Rural Women
Research Methods
Searching for numeric solutions to complex nonlinear equations is a resource-consuming, risky business. For a given equation, there can be an infinite number of often dramatically quite different solutions meeting a specified goodness-of-fit criterion. Although the leading statistical packages have nonlinear regression procedures, these procedures all require "seeding" with initial estimates of equation parameters. Often one has only the vaguest …

On the convergence of Das Gupta's model of fertility projection
A regression model expressing the age-specific fertility rates at a given point of time as a variable dependent upon the same at the preceding points of time has been developed by Das Gupta for purposes of fertility projection. The model, judged by the values of the multiple correlation coefficients, appears to work very well with the U.S. data set, and it also produces limiting values of the fertility rates when the projection is carried far int…
India's Historical Demography
Immigration, below-replacement fertility, and long-term national population trends
The long-term demographic effects of immigration on a population experiencing below-replacement fertility are studied by assuming that the size and age composition of the immigrant population do not change over time. The size of the first-generation immigrant population becomes stationary within a time period not greater than the human life span. Thereafter, the number dying equals the number entering over any given time interval. The stationarit…

On Espenshade’s comments on Mitra’s generalization
In responding to Professor Espenshade's comment on my (Mitra, 1983) paper let me begin with his finding the title misleading in the sense that for below replacement fertility Espenshade et al.'s (1982) results are more general than mine. According to him, this is so because I have assumed that immigrant women adopt the fertility pattern of the host country immediately. In order to derive my results, I used their model equation (Espenshade et al.,…
Estimating the expectation of life at older ages
A mathematical formula expressing the expectation of life e(a) at age a as a function of the death rate, the average age and the rate of growth of the population in the age interval a and above has been derived on the assumption of a stable population model. The formula is particularly helpful in estimating life expectancies at old ages, where the age and death statistics are of questionable accuracy in many countries. It is comforting to note th…
A simple model for linking life tables by survival-mortality ratios
Patterns of variation in mortality can be studied by measuring changes in selected life table functions. A model is proposed in which the rate of change over time in the life table survivorship probability at any age has been assumed as proportional to the product of its own value and its complementary probability or the probability of dying by that age, where the proportion is the same for all ages and depends only on the time duration between s…
On Das Gupta's `Birth Function in a Two-Sex Model
A short note on the taeuber paradox
When the force of mortality is reduced by a constant fraction 0 at every age, the relative increase in life expectancy e(0) can be measured by δH, where H is determined by the l(a) values of the life table. Although H is not easily reducible in terms of the well-known life table parameters, it has been shown that it can be approximately estimated by 2 – e(0)/à in which d is the average age of the stationary population. It has been found that, for…
On the derivation of a two-sex stable population model
It is well known that the intrinsic rates of growth derived separately for the males and females in a population, when one assumes the continuation of their respective mortality and fertility experiences, usually turn out to be different. Noting that the phenomenon of human reproduction is a product of the cooperation between the two sexes, we have attempted in this paper to define the sex-age-specific fertility rates as a function not only of ag…
Effect of adjustment for sex composition in the measurement of fertility on intrinsic rates
The inconsistencies inherent in the one-sex models created a need for the construction of what are known as marriage functions, especially for the measurement of fertility. But attempts to develop marriage functions have been frustrated by the inability of the proposed functions to meet certain consistency conditions and also by difficulties in empirically determining function parameters. Among several functions proposed so far, Das Gupta’s (1972…
Pearsonian Type I curve and its fertility projection potentials
New procedures are developed in this article for estimating parameters of the Pearsonian Type I curve which are particularly adaptive to factors influencing the pattern of age-specific fertility rates. It is shown that with this model the number of parameters required for the graduation and simulation of these rates can be reduced to only three—total fertility rate, mean and modal ages of fertility. The reduction in the number of fertility parame…
On the efficiency of the estimates of life table functions
Expected values and variances of several life table functions have been obtained by converting the sample estimates of age-specific mortality rates to probabilities of dying by Reed-Merrell’s approximation. The expressions also permit the development of a procedure that will enable the researcher, constrained usually by his limited resources, to maximize the efficiency of his sampling technique. Needless to say, these results will be particularly…
