Why People Do What They Do to Protect Against Earthquake Risk: Perceptions of Hazard Adjustment Attributes

This study examined respondents' self-reported adoption of 16 hazard adjustments (preimpact actions to reduce danger to persons and property), their perceptions of those adjustments' attributes, and the correlations of those perceived attributes with respondents' demographic characteristics. The sample comprised 561 randomly selected residents from three cities in Southern California prone to high seismic risk and three cities from Western Washington prone to moderate seismic risks. The results show that the hazard adjustment perceptions were defined by hazard-related attributes and resource-related attributes. More significantly, the respondents had a significant degree of consensus in their ratings of those attributes and used them to differentiate among the hazard adjustments, as indicated by statistically significant differences among the hazard adjustment profiles. Finally, there were many significant correlations between respondents' demographic characteristics and the perceived characteristics of hazard adjustments, but there were few consistent patterns among these correlations.     

Empirical studies of Posture-Gesture Mergers

This study describes four experiments which support the hypothesis that Posture-Gesture Mergers (PGMs) accompany verbal expressions that are truthful, relaxed, sincere, or authentic. PGMs are defined as body movements which occur when a posture (full body movement) leads into a gesture (partial body movement) or vice versa. Proportion of PGMs to nonPGMs constituted the dependent variable. Three experiments manipulated situational conditions in order to affect PGMs. In the first study, PGM behavior was compared when subjects were instructed to lie vs. when they were instructed to tell the truth. In the second study, PGM behavior was compared when subjects were frustrated vs. not frustrated by an experimental task. In the third study, PGM behavior was studied after subjects underwent relaxation training. The fourth study assessed naturally occuring PGM rates in a debate tournament and showed that PGMs are positively correlated with a judge's ratings of contestants' relaxation, sincerity, and effectiveness. Implications of the research for Action Profiling, as well as dance, movement, and body therapy, are addressed.This work was supervised and written by the senior author. Each of the junior authors designed one experiment and collected data, as well as served as a judge for a second experiment.     

Death anxiety in adolescents: the contributions of bereavement and religiosity

Possible relationships between bereavement and religiosity to death anxiety levels of adolescents were investigated. Scales measuring religiosity, bereavement, and death anxiety were incorporated into one questionnaire. Two hundred and twenty-six adolescents between the ages of 11 and 18 participated in the study based in urban and rural private schools within Manitoba. Females exhibited significantly higher death anxiety levels than did males; differences between the death anxiety levels of adolescents having a no-previous-death-experience death and those who had experienced a familial death were not significant; while religiosity levels were significantly higher for students attending religion-based schools, the relationships between measurements of religiosity and death anxiety were weak. Grief due to bereavement was the major factor in determining death anxiety for the adolescent.     

Recreation and agroforestry: Examining new dimensions of multifunctionality in family farms

Multifunctionality serves as an analytical framework to recognize many services that farms provide to their surrounding communities and society. This study explores an often overlooked dimension of multifunctionality by examining different recreational services provided by landowners in Missouri and analyzing the relationship between recreational multifunctionality and the practice of agroforestry. The latter provides multiple economic, environmental and beautification benefits that involve trees in the landscape. Results show that family farms provide several recreational services for their household members and others, and the existence of synergies between the recreational function of the farmland and agroforestry practices, consistent with the transition to strong multifunctionality. The recreational use of the land is positively associated to the cognitive (i.e., perceived knowledge) and affective (i.e., willingness to adopt) attitudes towards agroforestry. Results also show that the higher the perception of intrinsic (i.e., planting trees for wind protection and carbon sequestration) and economic (i.e., perceived economic benefits and flood protection) values of agroforestry, the more recreational use of the land. This study exemplifies the interactions between two little examined farmland functions providing insights for a comprehensive value assessment of family farms. Other academic and practical implications of the study are also detailed.     

Behavioral Activation and Inhibition, Negative Affect, and Gambling Severity in a Sample of Young Adult College Students

The prevalence of pathological gambling among college students is increasing. Few studies have directly examined the relation between reward processing and gambling severity while concurrently examining the effects of co-occurring negative affect in this at risk population. This study used Structural Equation Modeling (SEM) techniques to analyze results from an online survey of 352 female and 96 male students age 18-25. Participants completed measures of past year gambling behavior and severity of gambling problems using the Canadian Problem Gambling Index and the Problem Gambling Severity Index. Negative affect and reward processing were measured by the 21-item version of the Depression, Anxiety, and Stress Scales and the Behavioral Inhibition System and Behavioral Activation System (BIS/BAS) scales, respectively. Thirty-five percent of participants reported gambling in the previous 12 months, and 11% had gambling severity scores indicative of "moderate-risk" or "problem gambling." Gambling severity was associated with negative affect. Negative affect, in turn, was correlated with the unitary BIS scale and inversely associated with the BAS reward responsiveness scale. Reward responsiveness was also inversely associated with gambling severity. In the SEM models, the association between reward responsiveness and gambling severity was mediated by negative affect among males but not among females. Potential explanations for these findings and their implications for addressing problem gambling are discussed.     

Petty Crimes and Harassment: How Community Residents Understand Low-Level Enforcement in three High-Crime Neighborhoods in New York City

This paper examines how residents of high-crime communities understand so-called “quality of life” policing tactics and their effects on police-community relations. We demonstrate how focus groups offer a unique opportunity to understand how community members perceive police activity by giving research participants an opportunity to dialog with each other to collectively articulate the meanings of this complex issue. We draw on focus groups conducted in three New York neighborhoods with high levels of violence, police contact, poverty, and other indicators of concentrated disadvantage. One set of focus groups was conducted with Black and/or Latino males ages 16–20 living in each community, while another set was held with adult residents over age 30, who had lived in the community for at least 10 years. We closely examine how these two sets of community residents express concerns related to aggressive low-level enforcement actions in their communities and the concomitant issues of the over-policing of young men of color, the under-policing of what residents understand to be the primary threats to their personal safety, and the perceived lack of police accountability. We consider the implications of these findings for police-community relations more broadly.     

From susceptibility to frailty in social networks: The case of obesity

The obesity pandemic is represented by a discrete-time Hopfield Boolean network embedded in continuous-time population dynamics. The influence of the social environment passes through a system of differential equations, whereby obesity spreads by imitation of the most influential neighbors, those who have the highest centrality indices in the network. This property is called “homophily.” Susceptibility and frailty are redefined using network properties. Projections of the spread of obesity are validated on data collected in a French high school.
