Mediation analysis investigating the mechanisms of two school-based smoking prevention interventions in adolescents from Northern Ireland and Bogotá
Background Reviews have highlighted a lack of evidence on how successful intervention strategies for adolescent smoking prevention can be effectively adapted for low-middle income countries (LMICs). The MECHANISMS study compared behavioral mechanisms between two school-based smoking prevention programs for adolescents in Northern Ireland (NI; a high-income setting) and Bogotá, Colombia (middle-income). ASSIST works via peer education and diffusio…
Committee-Structured Games in a Cooperative Framework
We introduce the notion of committee-structured games (CSG) in a cooperative framework to analyze situations where committees affect players in generating their coalitional values. We represent the sets of committees by hypergraphs and obtain values as a function of both coalitions and hypergraphs. Based on how committee structures affect value generation, we present two models within the CSG framework. In the first model, the total value is gene…
From crisis to transformation
The COVID‐19 pandemic catalysed governments worldwide to rapidly implement large‐scale EdTech solutions. In India, the temporary shutdown of schools in March 2020 necessitated an improvement in the education sector's readiness for remote learning. This prompted the rapid evolution of the DIKSHA (Digital Infrastructure for Knowledge Sharing) platform, initially designed as a teacher‐centric digital repository, into a comprehensive national EdTech …

Multilayer network games
In this paper, we introduce the concept of a multilayer network game in a cooperative setup. We consider the notion of simultaneous contribution of individual players or links to two different networks (say, X and Z). Our model nests both classical network games and bi-cooperative network games. The calculation of the utility of players within a specific network in the presence of an additional/alternative network provides a broader spectrum of r…
Selection homophily and peer influence for adolescents’ smoking and vaping norms and outcomes in high and middle-income settings
The MECHANISMS study investigates how social norms for adolescent smoking and vaping are transmitted through school friendship networks, and is the first study to use behavioral economics methodology to assess smoking-related social norms. Here, we investigate the effects of selection homophily (the tendency to form friendships with similar peers) and peer influence (a social process whereby an individual’s behavior or attitudes are affected by p…
Socio-environmental and psychosocial predictors of smoking susceptibility among adolescents with contrasting socio-cultural characteristics
The findings illustrate that there were differences in predictors of adolescent smoking susceptibility across the two settings. By using a comparative approach we demonstrate that smoking interventions and policies must be sensitive to the cultural and normative context within which they are implemented
Probabilistic network values
Mechanisms Study
This proof of concept study harnesses novel transdisciplinary insights to contrast two school-based smoking prevention interventions among adolescents in the UK and Colombia. We compare schools in these locations because smoking rates and norms are different, in order to better understand social norms based mechanisms of action related to smoking. We aim to: 1) improve the measurement of social norms for smoking behaviors in adolescents and revea…
Do neighbourhood facilities matter for slum housing? Evidence from Indian slum clusters
Slum dwellers in developing countries reside in inhuman conditions, with little provision of basic facilities and with considerable overlap between sources of drinking water supply, sewerage and the area for garbage disposal. Is it because clean environment does not enter their decision function for residence selection or is it simply non-affordability? We examine these questions in the context of the registered slum clusters of four Indian citie…
New Patterns in Indian Urbanization
This study focuses on the new patterns related to urbanization in India from the 2011 census data, particularly with regard to the emergence of the census towns. What forces are involved in explaining the growth of such towns is an important question and this is what the present article tries to explore. The regional spread of these census towns is examined and based on the district-level data, the growth dynamics of such reclassification of area…
