Objectives—The current study examines the prevalence of health risk behaviors and their cumulative effects on cardiovascular disease (CVD) among a sample of adults. Age cohort is also examined to determine the role of age in predicting CVD and risky health behaviors. Method—Medical records of a sample of adults from the Seattle Longitudinal Study categorized into one of four age-group cohorts w...

The present study explored the relationship between risky cybersecurity behaviours, attitudes towards cybersecurity in a business environment, Internet addiction, and impulsivity. 538 participants in part-time or full-time employment in the UK completed an online questionnaire, with responses from 515 being used in the data analysis. The survey included an attitude towards cybercrime and cybers...

In this study, respondents from the P.R.C., U.S.A., Germany, and Poland were found to differ in risk preference, as measured by buying prices for risky financial options. Chinese respondents were significantly less risk-averse in their pricing than Americans when risk preference was assessed in the traditional expected-utility framework. However, these apparent differences in risk preference we...

This paper characterizes conditions under which a risky coupon bond is equivalent to a portfolio of risky zero-coupon bonds. This characterization is extended to enable the estimation of firm specific zero-coupon bond prices from risky coupon bond prices for the determination of firm specific credit risk curves.  2004 Elsevier Inc.

We examine how different types of risk presentation numerical descriptions, experience sampling, graphical displays, and a combination of these formats in a ‘risk tool simulation’influence asset allocations in an experimental investment portfolio. Participants viewed information about a risky and a risk free fund and made a portfolio allocation. Risky allocations were elevated in the risk tool ...

BACKGROUND Risky decision-making is commonly observed in persons at risk for and infected with HIV and is associated with executive dysfunction. Yet it is currently unknown whether HIV alters brain processing of risk-taking decision-making. METHODS This study examined the neural substrate of a risky decision-making task in 21 HIV seropositive (HIV+) and 19 seronegative (HIV-) comparison parti...

Current combination antiretroviral therapies (ARV) are widely used to treat HIV. However drug-resistant strains of HIV have quickly evolved, and the level of risky behaviour has increased in certain communities. Hence, currently the overall impact that ARV will have on HIV epidemics remains unclear. We have used a mathematical model to predict whether the current therapies: are reducing the sev...

The present study examines the individual and joint contributions of personality, situations, and relationship contexts as they shape risky sexual behaviors. Data on 7,511 discrete sexual events collected from a community sample of 1,946 young adults were analyzed with multilevel modeling. Results showed that meaningful between-persons differences in risky sexual behavior exist and that these d...
