In a Multi-Variant Execution Environment (MVEE), several slightly different versions of the same program are executed in lockstep. While this is done, a monitor compares the behavior of the versions at certain synchronization points with the aim of detecting discrepancies which may indicate attacks. As we show, the monitor can be implemented entirely in(More)
While memory-safe and type-safe languages have been available for many years, the vast majority of software is still implemented in type-unsafe languages such as C/C++. Despite massive concerted efforts by software vendors such as Microsoft to eliminate buffer overflow vulnerabilities through automated and manual code review, they continue to be found and(More)
This research presents four studies on the initial development and validation of the 48-item Negative Physical Self Scale (NPS), a multidimensional measure of body image concerns for use with Chinese samples. In Study 1 (N=1095), exploratory factor analyses identified five dimensions underlying the NPS (General Appearance, Facial Appearance, Shortness,(More)

In this experiment, sensitivity to female facial attractiveness was examined by comparing event-related potentials (ERPs) in response to attractive and unattractive female faces within a study-test paradigm. Fourteen heterosexual participants (age range 18-24 years, mean age 21.67 years) were required to judge 84 attractive and 84 unattractive face images(More)
UNLABELLED A meta-analysis was performed to evaluate overall strengths of relation between self-efficacy (SE) and functioning (pain severity, functional impairment, affective distress) in chronic pain samples, as well as potential moderating effects of sociodemographic characteristics and methodologic factors on these associations. In sum, 86 samples (N =(More)
Previous event-related potential (ERP) and brain imaging studies have suggested observer responses to others’ pain are modulated by various bottom-up and top-down factors, including emotional primes. However, the temporal dynamics underlying the impact of emotional primes on responses to others’ pain remains poorly understood. In the present study, we(More)
This research assessed the prevalence and sociodemographic correlates of eating disorder symptoms among young people from China. A sample of 1320 females and 783 males between 12 and 22 years of age was recruited from academic settings in various regions of China and completed a back-translated Chinese version of the Eating Disorder Diagnostic Scale, as(More)
