Objectives This experiment tested whether changing the location or visibility of the tobacco power wall in a life sized replica of a convenience store had any effect on adolescents’ susceptibility to future cigarette smoking. Methods The study was conducted in the RAND StoreLab (RSL), a life sized replica of a convenience store that was developed to experimentally evaluate how changing aspects of tobacco advertising displays in retail point-of-sale environments influences tobacco use risk and behavior. A randomized, between-subjects experimental design with three conditions that varied the location or visibility of the tobacco power wall within the RSL was used. The conditions were: cashier (the tobacco power wall was located in its typical position behind the cash register counter); sidewall (the tobacco power wall was located on a sidewall away from the cash register); or hidden (the tobacco power wall was located behind the cashier but was hidden behind an opaque wall). The sample included 241 adolescents. Results Hiding the tobacco power wall significantly reduced adolescents’ susceptibility to future cigarette smoking compared to leaving it exposed (i.e., the cashier condition; p = .02). Locating the tobacco power wall on a sidewall away from the cashier had no effect on future cigarette smoking susceptibility compared to the cashier condition (p = 0.80). Conclusions Hiding the tobacco power wall at retail point-of-sale locations is a strong regulatory option for reducing the impact of the retail environment on cigarette smoking risk in adolescents.

Previous research has shown an 'interindividual-inter-group discontinuity effect': inter-group interactions generally lead to less cooperative outcomes than interindividual interactions. In this dissertation, I replicate the discontinuity effect in the deterministic prisoner's dilemma, but find that groups are more cooperative than individuals in a stochastic version of the game.Three major factors that underlie the usual discontinuity effect, were reduced in the stochastic environment: greed, fear, and persuasion power. Two group mechanisms are proposed to explain the reversed discontinuity effect: the motivation to avoid guilt and blame when making decisions that affect others' welfare, and the social pressure to conform to certain norms when one is in a group setting. Follow-up studies reject the social pressure mechanism, but confirm that guilt aversion and blame avoidance drive groups to be more risk concerned than individuals and more likely to invest to reduce risks when uncertainty is present. There is also evidence that iii uncertainty reduces inter-group distrust that usually exists in group interactions, and may even increases inter-group trust to be higher than inter-individual trust.iv

Aging has become a worldwide issue in the 21st century. China became an aging society in 1999, and home-based care is now the main mode of care for the elderly. Present research on the aging-suitability of spaces mainly focuses on the interior and exterior environmental conditions of the home, ignoring public open spaces at the regional and urban levels, with a specific lack of research on waterfront open spaces, which is an important type of public open space in Jiangnan Watertown. The study used the example of the waterfront space of the Hangzhou Gongchen Bridge section of the Grand Canal, the longest artificial canal in the world, to analyze the aging-suitability of waterfront open spaces. Firstly, in this section, the activity characteristics of the elderly were surveyed through observation and semi-structured interviews, then the subjective satisfaction of the elderly with the waterfront spaces was investigated. Through correlation and principal component analysis, five common factors affecting the satisfaction of the elderly were obtained: environment, function, transportation, social culture, and vision. Finally, some design suggestions suitable for the elderly were proposed for three aspects: environment, function, and transportation, which are the most important factors affecting the overall subjective satisfaction of the elderly with the waterfront open space. This study provided a reference for the design and planning of aging-friendly waterfront open spaces, which would improve the aging-suitability of urban open spaces, increasing social participation, and enhancing the quality of life of the elderly. It is of profound significance to build a senior-friendly city and deal with the increasingly severe aging problem.

The tobacco power wall increases adolescents' smoking risk, and this effect is partly explained by the effect of the power wall on adolescents' perceptions of how normative smoking is. (PsycINFO Database Record
