Helping Individuals to Understand Synergistic Risks: An Assessment of Message Contents Depicting Mechanistic and Probabilistic Concepts

Accumulating evidence shows that certain hazard combinations interact to present synergistic risks. However, little is known about the most effective ways of helping individuals to understand this complex risk concept. More specifically, there is an absence of empirical research that has assessed the relative efficacy of messages that explain either the causal mechanism and/or the probabilistic components of synergistic risks. In an experiment designed to address this issue, we presented participants with messages concerning the synergistic risk of developing esophageal cancer for individuals who consume both tobacco and alcohol. Relative to a control group, we compared the extent to which messages featuring content detailing the underlying biological mechanism, the probabilistic risk, or both improved understanding of the synergistic risk. Our results showed that messages containing details of both the mechanism and probabilistic information were most effective at enabling individuals to understand that the alcohol‐tobacco combination presents a synergistic risk. In addition, large improvements in the accuracy of cancer frequency estimates were observed amongst individuals who received probabilistic information, and the highest relative increase in professed willingness to adopt precautionary behaviors was observed amongst individuals who received the mechanism information only. Importantly, these findings could be utilized in the development of a general model for the communication of synergistic risks. Furthermore, in contrast to previous findings, our study demonstrates that risk messages can be both effective and efficient in helping individuals to acquire a greater understanding of synergistic risks. Acquiring such knowledge could lead to significant improvements in risk‐related decisions concerning combined hazards.     

Strategic interaction sequences: the institutionalization of participatory budgeting in New York City

ABSTRACT

An interactive approach to social movements highlights time dynamics in ways more correlational approaches do not, in that interaction and outcomes unfold in sequences as players react to one another. Some aspects of these engagements are shaped by institutional schedules, while others leave discretion to the players. Some institutional schedules, meanwhile, may be reshaped by strategic interactions. By examining the implicit trade-offs and explicit dilemmas that pervade strategic interaction, we see how some are tightly linked to time whereas others more closely reflect ongoing structural situations. Analyzing the case of participatory budgeting in New York City, we focus on two trade-offs, ‘being there’ and ‘powerful allies’, that appear when social movements attempt to institutionalize new policies and processes. These time-based strategic trade-offs complicate activists’ efforts to secure lasting gains.     

Reduced inhibitory control predicts persistence in laboratory slot machine gambling

Impairments in inhibitory control characterize a range of addictive behaviours including gambling disorder. This study investigated the relationship between a neuropsychological measure of inhibitory control and behaviour on a simulated slot machine that included a measure of gambling persistence, in a non-clinical sample of regular gamblers. Regular gamblers (n = 75) performed a laboratory slot machine task for 30 trials where they could win real money, followed by a persistence phase under extinction (i.e. without wins). Participants also completed a stop-signal task, along with measures of gambling-related cognitions, social desirability, and symptoms of disordered gambling. In hierarchical regression models, reduced inhibitory control was found to predict greater persistence and a higher subjective desire to play again after both wins and near-misses (i.e. unsuccessful outcomes close to the jackpot). These data illustrate the impact of low inhibitory control on relevant behavioural tendencies in a group of regular gamblers. Our results help elucidate a cognitive process that may contribute to problem gambling, with implications for screening and treatment.     

Do People Believe Combined Hazards Can Present Synergistic Risks?

The risk attributable to some hazard combinations can be greater than the sum of the risk attributable to each constituent hazard. Such "synergistic risks" occur in several domains, can vary in magnitude, and often have harmful, even life-threatening, outcomes. Yet, the extent to which people believe that combined hazards can present synergistic risks is unclear. We present the results of two experimental studies aimed at addressing this issue. In both studies, participants examined synergistic and additive risk scenarios, and judged whether these were possible. The results indicate that the proportion of people who believe that synergistic risks can occur declines linearly as the magnitude of the synergistic risk increases. We also find that people believe, despite scientific evidence to the contrary, that certain hazard combinations are more likely to present additive or weakly synergistic risks than synergistic risks of higher magnitudes. Furthermore, our findings did not vary as a simple function of hazard domain (health vs. social), but varied according to the characteristics of the specific hazards considered (specified vs. unspecified drug combinations). These results suggest that many people's beliefs concerning the risk attributable to combined hazards could lead them to underestimate the threat posed by combinations that present synergistic risks, particularly for hazard combinations that present higher synergistic risk magnitudes. These findings highlight a need to develop risk communications that can effectively increase awareness of synergistic risks.     

On Insurrectionality: Theses on Contemporary Revolts and Resilience

Abstract

This analysis asks are civil uprisings by adaptable popular resistance groups of insurrectionists openly allowed in today's unstable world system? Does power legitimize its rule by constantly sparking revolts only to contain and suppress them in spectacles of control to evince the resilience of established regimes? Such embedded cycles of regimes collapsing, and then reconstructing their rule, illustrate this dynamic of ‘insurrectionality’. Like other ideologies of good works, including ‘accountability’, ‘diversity’, or ‘sustainability’, do the logics of insurrectionality unfold tactics of flexible control to maintain a new globalized regime of resilient power? An emergent logic for maintaining order might mobilize disorder to generate new power and knowledge for renewing order. And, these strategies appear to be implemented by permitting groups of insurrectionists to exist openly and tolerate, to a large degree, the legitimacy of insurrectionism as a civil/political/social freedom, if not, a new type of right.     

DETECTING INFLUENTIAL OBSERVATIONS IN SLICED INVERSE REGRESSION ANALYSIS

The detection of influential observations on the estimation of the dimension reduction subspace returned by Sliced Inverse Regression (SIR) is considered. Although there are many measures to detect influential observations in related methods such as multiple linear regression, there has been little development in this area with respect to dimension reduction. One particular influence measure for a version of SIR is examined and it is shown, via simulation and example, how this may be used to detect influential observations in practice.
