The key role of risk perception in preparedness for oil pipeline accidents in urban areas: A sequential mediation analysis

Effective disaster risk reduction requires conducting research within communities that gave recognized natural or technological risks, to foster the development of more resilient societies. However, limited information is available regarding risk perception and preparedness for technological hazards in disaster-prone urban areas of South America. The aim of this study is to investigate the factors that influence public risk perception regarding the Trans-Ecuadorian Oil Pipeline System and its relationship with household preparedness for a potential accident in the Metropolitan District of Quito (Ecuador). We assess the link among knowledge, trust in authorities, risk perception, intention to prepare, and preparedness. Results from a sequential mediation analysis reveal that risk perception partially and positively mediates the relationship between knowledge and preparedness and acts as a negative full mediator between the latter and trust. These findings provide valuable information for future risk governance and communication strategies, aimed at enhancing risk perception and improving individual preparedness of individuals, as well as risk mitigation procedures

Delegation and strategic altruism, a theoretical approach
Méndez Naya, Luciano
In this paper we introduce two refinements of Nash equilibria for extensive form games: the quasi-stable equilibrium and the stable equilibrium. We then introduce the general strategic game with delegates and study the new solutions in that context. We apply the new solution concepts to symmetric n-player games in which each player has two strategies. The main conclusion is that, in the prisoner's dilemma, if the punishment payoff is sufficient, when both players choose strategically altruistic delegates they can obtain the cooperative payoff.

Social capital dimensions and subjective wellbeing: A quantile approach
Neira Gómez, Isabel; Lacalle-Calderón, Maricruz; Portela, Marta; Pérez Trujillo, Manuel
This paper investigates the effects of the different dimensions of social capital (i.e., trust, social
network and civic engagement-including norms) on subjective well-being (SWB) at the individual
level by attending to differences between the extremes of SWB distribution, this is between the
happiest and unhappiest people. To this end, we use the 7
th wave of the 2014 European Social
Survey (ESS) to run a quantile regression analysis to investigate whether any of these dimensions
of social capital has a heterogeneous effect on the full distribution of well-being. We also perform
a factor analysis to summarize the principal components of these three dimensions. Our results
show that each dimension of social capital has a positive and significant correlation with SWB,
but the different dimensions have a heterogeneous effect on the different quantiles of the wellbeing distribution. All of these dimensions of social capital have a stronger effect on the SWB of
the least happy people in society than on the happiest.

Individual well-being, geographical heterogeneity and social capital
Neira Gómez, Isabel; Bruna, Fernando; Portela, Marta; García-Aracil, Adela
This paper argues the relevance of analysing the origins of contextual effects to explain subjective wellbeing (SWB). Using the 2012 European Social Survey, the study applies social capital indicators to distinguish
between-context and between-individual heterogeneity in three multilevel models of happiness and life satisfaction. Five indicators of social capital at individual and regional level are used to measure the trust, networks and
norms dimensions of social capital. Random intercept and random slope hierarchical models are used to control
for unexplained regional variability. The possibility of aggregated subjective perceptions conditioning, or interacting with, the effects of individual perceptions is also examined. The results show that the regional means of
the social capital indicators are useful in explaining not only average levels of SWB (between-context heterogeneity) but also differences in the importance individuals attribute to their social capital (between-individual heterogeneity). The paper also proposes a research agenda to expand the frontier on contextual effects in the new
science of well-being
