The dual systems model posits that adolescent risk-taking results from an imbalance between a cognitive control system and an incentive processing system. Researchers interested in understanding the development of adolescent risk-taking use a diverse array of behavioral and self-report measures to index cognitive control and incentive processing. It is currently unclear whether different measur...

The fast changing environment and the complexity of projects has increased risk exposure. The PMBOK proposes a structured risk management process, integrated within the overall project management framework. However, unresolved difficulties call for further developments in the field. In projects, risks take place within a complex web of numerous interconnected causes and effects, which generate ...

Objective: Diabetic patients are more likely to be infected and are at the higher risk of morbidity and mortality in COVID-19 pandemic. The aim of this study was to compare the preventive behaviours and perceived risk of COVID-19 in women with and without type 2 diabetes mellitus (T2DM). Materials and Methods: The analytical cross-sectional study was conducted from June to July 2020 on 151 par...

Valuable monetary rewards can boost human performance on various effortful tasks even when the value of the rewards is presented too briefly to allow for strategic decision making. However, the mechanism by which briefly-presented reward information influences performance has remained unclear. One possibility is that performance after briefly-presented reward information is primarily boosted vi...

Adolescents involved in criminal activity have been found to have markedly higher rates of HIV risk-taking than their peers who are not incarcerated. This sample of 300 adolescents in detention in New South Wales in 1999 revealed high levels of substance use and HIV risk-taking behaviours compared with their school attending peers. More than a third of the sample had injected a drug and 29% use...

OBJECTIVES This paper sought to identify the behaviour change targets for an injury prevention program; Skills for Preventing Injury in Youth (SPIY). The aim was to explore how such behaviours could subsequently be implemented and evaluated in the program. METHODS AND DESIGN The quantitative procedure involved a survey with 267 Year 8 and 9 students (mean age 13.23 years) regarding their enga...

Governments try to discourage risky health behaviours, yet such behaviours are bewilderingly persistent. We suggest a new conceptual approach to this puzzle. We show that expected utility theory predicts that unhappy people will be attracted to risk-taking. Using US seatbelt data, we document evidence strongly consistent with that prediction. We exploit various methodological approaches, includ...

this work concerns the situations in which the framing effects emerge. this has not been an established feature in different studies, so the reasons for its variations have been the subject of various studies since 1980s. present study aimed to determine the variables affecting the feature as well as to address the controversies exist on how these variables affect it. 551 students from engineer...
