Non communicable disease is the leading cause of death globally. Non communicable diseases (NCDs) kill 38 million people each year. This study aims to estimate the prevalence rate of NCD risk factors among adult population and to determine the association between behavioural and metabolic risk factors. Methods: This is a cross sectional descriptive study carried out in the rural field practice area attached to a Medical college in Kancheepuram district. The study group were 370 adults (20-60 years). The data was collected using a structured questionnaire with the help of WHO steps approach containing socio-demographic particulars, details regarding NCD risk factors and physical measurements. Data was analysed using SPSS 15 software. Prevalence of NCD risk factors was calculated using percentages and strength of associa...

In the current political-economic regime, no country does so. Here, we assess which socioeconomic conditions might enable societies to satisfy human needs at low energy use, to reconcile human well-being with climate mitigation. Using a novel analytical framework alongside a novel multivariate regression-based moderation approach and data for 106 countries, we analyse how the relationship between energy use and six dimensions of human need satisfaction varies with a wide range of socioeconomic factors relevant to the provisioning of goods and services ('provisioning factors'). We find that factors such as public service quality, income equality, democracy, and electricity access are associated with higher need satisfaction and lower energy requirements ('beneficial provisioning factors'). Conversely, extractivism and economic growth beyond moderate levels of affluence are associated with lower need satisfaction and greater energy requirements ('detrimental provisioning factors'). Our results suggest that improving beneficial provisioning factors and abandoning detrimental ones could enable countries to provide sufficient need satisfaction at much lower, ecologically sustainable levels of energy use. However, as key pillars of the required changes in provisioning run contrary to the dominant politicaleconomic regime, a broader transformation of the economic system may be required to prioritise, and organise provisioning for, the satisfaction of human needs at low energy use.

This is an important and active field of research with significant relevance for empirical studies in a variety of subjects including economics, finance, social sciences, health etc. This book presents contributions by several leading experts who provide their views on a wide range of topics, both theoretical and applied, that can serve as a basis for future research on the methodology and applications of panel data modelling. Areas of application of panel data modelling have only been increasing over the past years and there is no doubt that the range is going to expand further. The applied papers of this book have been regrouped as one major part and further subdivided into different fields, thus showing their variety and opening up the horizon for researchers in these and other fields. The reader will notice that they all have a substantial methodological content which is indispensable for their analysis of the economic, social or other phenomena under consideration. This first part includes such diversified areas of study as macroeconomics, social economics, insurance/finance and energy economics. As a second part, there are papers that deal more with theoretical issues such as specification problems, unit root tests and aggregation of individual series, heteroscedasticity tests for panel data models and non-parametric techniques. The final part contains papers that are directly related to and elaborate on Balestra's work.

If individuals care about the welfare of others (including future generations) they can be expected to unilaterally adapt their behaviour to preserve the common good thus enhancing the wellbeing of all. We introduce a network game model featuring both altruism and a public good (e.g. climate) whose degradation affects all players. As expected, in an idealistic fully connected society where all players care about each other, increasing altruism results in a better protection of the public good. However, in more realistic networks where people are not all related to each other, we highlight an intrinsic trade-off between the effects of altruism on reducing inequality and the preservation of a global public good: the consumption redistribution generated by a higher altruism is partly achieved by lowering income transfers towards protection of the public good. Therefore, it ...

Specifically, it reports on the development and delivery of a survey instrument for measuring capabilities, calculates for each respondent a Nehring-Puppe type index of capabilities and examines the distribution of index scores. The main analytic part of the paper then goes on to develop a generalized linear latent and mixed model (GLLAMM) for assessing the impact of capabilities on life satisfaction, in which allowance is made for (i) unobserved heterogeneity and (ii) possible endogeneity, by introducing latent individual effects and by instrumenting capability variables using income and other socioeconomic variables. Our empirical results show that empathy, self-worth, goalautonomy, discrimination, safety and stress are statistically significant determinants of life satisfaction, in a decreasing order of importance. The paper concludes by suggesting that, if replicated, the findings have profound implications for the conceptualisation and evaluation of economic progress.

As India hosts one of the world’s largest vaccine manufacturing industries and has one of the most extensive vaccination strategies, the country is particularly exposed to these challenges. This has become all the more obvious as the country experienced a second pandemic wave in the first half of 2021, which has led to a total ban on exports of COVID-19 vaccines. An analysis of the national vaccination strategy and the domestic vaccine industry through review of peer-reviewed literature, grey literature, and news reports showed the fragile balance between domestic and international needs. A numerical comparison of India’s domestic COVID-19 vaccine needs, export agreements, and production capacities was conducted. It was found that at current production rates as of April 2021, meeting al...

This paper is an attempt to answer this question using as a theoretical framework the capability approach. We use data collected on 8841 individuals above 60 living in France (the 2008 Disability and Health Household Survey) and propose a latent variable modelling framework to analyse their capabilities in two fundamental dimensions: freedom to perform self-care activities and freedom to participate in the life of the household. Our results show that living as a couple, having children, being mobile and having access to local shops, health facilities and public services enhance both capabilities. Age, household size and male gender (for one of the two capabilities) act as impediments while the number of impairments reduces both capabilities. We find that people with Alzheimer's disease have a lower level and a smaller range of capabilities (freedom) when compared to those without, even when the latter have several impairments. Hence they need a special attention in policy-making.

Most studies focus on a single (monetary) wellbeing indicator and take individual efforts as being randomly distributed. However, recent development theories have uniformly advocated the use of a multidimensional wellbeing measure and the importance of individual responsibility. We propose a theoretical framework and a modelling tool to include these aspects in an assessment of the connection between public policies and inequality of opportunity for wellbeing within a Romerian setting. Using Bolivian data, we demonstrate the empirical usefulness of our framework and find that Bolivian social programmes are strongly associated with the reduction of unfair inequalities arising from ethnicity and family background, although their levels are far away from being optimal. We highlight the role of effort in this connection and show that it i...
