Status And Smoking In Assist. A Longitudinal School‐based Study Of Uk Adolescents.Steglich, Christian; Holliday, Jo; Mercken, Liesbeth; Moore, LaurenceNetwork DynamicsSmoking, Actor‐Based Stochastic Modeling, sociometric statusTHURS.PM1The status of an adolescent among his peers is partly determined by the social class he comes from, and partly by popularity among his peers. Previousresearch has identified a negative relationship between social class and adolescent smoking behaviour, and a positive relationship between peer popularityand adolescent smoking behaviour. If smoking causes adolescents to become more popular, smoking may be perceived as a viable strategy notably for lowerclass students to gain status among their peers. This study uses longitudinal data collected in the UK‐based A Stop Smoking in Schools Trial (ASSIST) to assesseswhether a possible association between measures of sociometric status and smoking results from processes of peer selection (smokers gaining status amongtheir peers) or from processes of peer influence (high status students starting to smoke), and which role social class in the form of family affluence plays inthese processes. Suggestions for the future development of adolescent smoking interventions will be discussed.Stratification And Nested Structure Of Small World In A Friendship NetworkTomochi, Masaki; Tanaka, Atsushi; Shichijo, TatsuhiroSmall World ResearchSimulation, Small World, Data, Friendship Network, Social Distance, Spatially‐embedded NetworksTHURS.AM2We have analyzed effects of spatial and social distance on a friendship network. We used the data obtained from “Tomocom.jp” which is a social networkservice where approximately 300 undergraduate students living in several areas in Japan are participating. From the data, we have found that spatial and socialdistance between individuals causes stratification in the friendship network and brings about nested structure of small world. Based on what we have found inthe data analysis, we have built a model and successfully replicated the nested structure of small world.
