In the last years, increasing smartphones’ capabilities have caused a paradigm shift in the way of users’ view and using mobile devices. Although researchers have started to focus on behavioral models to explain and predict human behavior, there is limited empirical research about the influence of smartphone users’ individual differences on the usage of security measures. The aim of this study is to examine the influence of individual differences on cognitive determinants of behavioral intention to use security measures. Individual differences are measured by the Five-Factor Model;cognitive determinants of behavioral intention are adapted from the validated behavioral models theory of planned behavior and technology acceptance model. An explorative, quantitative survey of 435 smartphone users is served as data basis. The results suggest that multiple facets of smartphone user’s personalities significantly affect the cognitive determinants, which indicate the behavioral intention to use security measures. From these findings, practical and theoretical implications for companies, organizations, and researchers are derived and discussed.

他汀类药物应用和痴呆发病风险的心血管健康研究

Background: Statins (3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors) reduce cardiovascular risk through mechanisms that might affect the development of dementia. Abstract:Objective: To evaluate whether statin use is associated with a lower risk of dementia compared with never use of lipid-lowering agents (LLAs). Design: Cohort study of community-dwelling adults 65 years and older. The analysis included 2798 participants free of dementia at baseline. Main Outcome Measures: Using Cox proportional hazards regression analysis, we estimated the risk of incident all-cause and type-specific dementia associated with time-dependent statin therapy compared with never use of LLAs. The primary analyses incorporated a 1-year lag between exposure and outcome. Secondary analyses included the final year of exposure and modeled statin use as current use vs nonuse to simulate a case-control approach. Results: Compared with never use of LLAs, ever use of statins was not associated with the risk of all-cause dementia (multivariable-adjusted hazard ratio [hR], 1.08; 95%confidence interval [CI], 0.77-1.52), Alzheimer disease alone (hR, 1.21; 95%CI, 0.76-1.91), mixed Alzheimer disease and vascular dementia (hR, 0.87; 95%CI, 0.44-1.72), or vascular dementia alone (hR, 1.36; 95%CI, 0.61-3.06). In contrast, in secondary analyses, current use of statins compared with nonuse of LLAs was associated with hRs of 0.69 (95%CI, 0.46-1.02) for all-cause dementia and 0.56 (95%CI, 0.35-0.92) for any Alzheimer disease. Conclusions: In this cohort study, statin therapy was not associated with a decreased risk of dementia. Methodological differences may explain why results of this cohort investigation differ from those of prior case-control studies. Additional investigation is needed to determine whether and for whom statin use may affect dementia risk.
