Carbon emission is a significant issue for the current business market and global warming. Nowadays, most countries have focused to reduce the environmental impact of business with durable financial benefits. The purpose of this study is to optimize the entire cost functions with carbon emission and to find the sustainable optimal ordering quantity for retailers.

This paper illustrates a sustainable inventory model having a set of two non-instantaneous substitutable deteriorating items under joint replenishment with carbon emission. In this model demand and deterioration rate are considered as deterministic, constant and triangular fuzzy numbers. The objective is to find the optimal ordering quantity for retailers and to minimize the total cost function per unit time with carbon emission. The model is then solved with the help of Maple software.

This paper presents a solution method and also develop an algorithm to determine the order quantities which optimize the total cost function. A numerical experiment illustrates the improvement in optimal total cost of the inventory model with substitution over without substitution. The graphical results show the convexity of the cost function. Finally, sensitivity analysis is given to get the impact of parameters and validity of the model.

This study considers a set of two non-instantaneous substitutable deteriorating items under joint replenishment with carbon emission. From the literature review, in the authors’ knowledge no researcher has undergone this kind of study.

The purpose of this paper is to provide a quantitative assessment of caste-based conflict in India. The data for this paper are from the Rural Economic and Demographic Survey (REDS) of 2006 encompassing 8,659 households in 242 villages in 18 Indian states.

Using these data, the authors examine two broad issues: the sources of conflict in rural India and the degree to which these sources contribute to caste-basted, as opposed to non-caste-based conflict; the sources of conflict resolution in rural India: are some conflict-resolving agencies more effective at dealing with caste-based conflicts and others more effective with non-caste-based conflicts?

There was a rise in caste-based conflict over the (approximate) period 1996-2006. There are several reasons for the rise in caste-based conflict but, in the main, is the rise in assertiveness of persons belonging to India’s lower castes. In terms of conflict resolution, panchayats and prominent individuals were important in resolving village conflicts: 69 per cent of caste-based, and 65 per cent of non-caste based, conflicts were resolved by one or the other of these two agents.

This is the first attempt, using econometric methodology, to study caste conflict at a village level in India.

Fertility aspirations shape family planning behavior of a couple. Desire to have certain number of children is linked with various micro- and macro-level factors such as individuals’ characteristics, sociocultural contexts and unconscious personal motivations. Fertility aspirations are an important component of fertility decision-making and a major predictor of childbearing. In India, Uttar Pradesh (UP) is the most populated state with historically high levels of fertility rates as compared to national average. This research is a qualitative exploration of the perspectives and practices of women with respect to their fertility aspirations and family planning behavior in an urban setting. A cross-sectional study was conducted between August 2017 and July 2018 among married women and men of the reproductive age group of 17–49 years using qualitative methods. The study was done in Pakbara, a Census Town (has a minimum population of 5,000) in the district of Moradabad, situated in western UP. It was found that along with personal motivations of having a quality life change in objective circumstances has led to changes in the fertility aspirations of the participants, particularly women. Increasing education, more mobility in public spaces, aspirations for a quality life, exposure to mass media and new job opportunities generate revision of parental aspirations. Couples, particularly from middle and upper-middle classes, limit their family size to attain upward social mobility. Couples from lower economic class have realized that rise of household income has not been commensurate with rise in prices. Thus, restricted childbearing is one way to cope with the situation.

The purpose of this paper is to examine the extent to which workplace policies and practices are related to participation in, and frequency and duration of, workplace training, controlling for worker and workplace characteristics.

The authors regress variables depicting participation, frequency and duration of workplace training on workplace policies and control variables. In the case of participation in training, the dependent variable is binary; hence, the authors use a logit model. To examine the number of times which employees participate in training and the number of days they spend training the authors use a Tobit model. The Lewbel (2012) method is used to examine whether there is a causal relationship between workplace policies and the frequency, and duration, of training.

The findings suggest that about half of the workplace policies considered are positively correlated with the incidence and breadth of workplace training. There is also some support for the view that bundling of policies is positively correlated with the provision of workplace training. The Lewbel (2012) results suggest a causal relationship between a bundle of workplace policies and the frequency, and duration, of workplace training. There is, however, no evidence that workplace policies designed to devolve responsibilities to workers and incentivize staff polarizes skills through resulting in more training for professional staff over others.

The authors use matched employer and employee cross-sectional data for Shanghai in China. To this point most studies that have examined the determinants of training use data for Europe or the USA. There are few studies of this sort for countries in other regions and, in particular, developing or transition countries. There are no studies at all on the relationship between workplace policies and practices designed to promote organizational performance and training in developing or transitional countries. This study addresses this gap in the understanding of the factors related to on-the-job training in transitional countries, such as China.

The purpose of this paper is to use cross-sectional data collected from six cities in China to examine the relationship between subjective wellbeing and male and female earnings and also to consider the contribution of differences in subjective wellbeing to explaining the gender wage gap.

The paper uses survey data for 3,390 respondents working in a variety of blue collar and white collar jobs across a range of sectors including government, heavy and light manufacturing, mining and services in six Chinese cities: Chengdu, Dalian, Fushun, Fuxin, Fuzhou and Wuhan. The authors employ the ordinary least squares, Lewbel instrumental variable and Blinder-Oaxaca decomposition to econometrically analyze the relationship between subjective wellbeing and gender wage gap.

The paper finds that the relationship between subjective wellbeing and wages is stronger for males than females. The authors note that 0.2 percent of the observed gender wage gap can be attributed to differences in mean subjective wellbeing in favor of females, while 53.5 percent can be ascribed to gender differences in returns to subjective wellbeing in favor of males. The paper also finds evidence that the relationship between subjective wellbeing and income is non-linear and that income peaks at higher levels of subjective wellbeing for men than women.

The paper extends the existing literature in three important ways. First, the authors use a novel identification strategy, proposed by Lewbel (2012); second it uses a better measure for subjective wellbeing and third, it examine the role of differences in subjective wellbeing in explaining the gender wage gap.

One of the main sustainable development goals (SDGs) highlights gender equality. Gender inequality is usually measured through the Gender Inequality Index (GII) based on three main dimensions, namely, (1) economy, (2) social empowerment, and (3) reproductive health, as demonstrated by death ratio and fertility rates. The aim is to formulate a model for women’s empowerment towards achieving the SDGs. Specifically, the objectives include (1) comparing gender inequality levels among ASEAN countries and (2) analyzing regulations on gender and development perspectives in Indonesia. This research used the mixed method and panel data, namely analyzing gender inequality.

The results show that, in the common effect model, all variables affected the participation of women in the workforce. The analysis shows that the enactment of laws and regulations on gender mainstreaming has an impact on reducing gender inequality and increasing various indicators of gender mainstreaming, especially in increasing the participation of women in the workforce.
