OBJECTIVES To examine the validity of self reported data on safety belt use and to consider the implications for research on injury prevention behaviors. METHODS 1992 and 1993 self reported data on safety belt use were obtained from the Behavioral Risk Factor Surveillance System and observational data were obtained from the National Highway Traffic Safety Administrations for 49 states in 1992...

The purpose of this research is to achieve uniform spatial resolution in CT (computed tomography) images without hardware modification. The main idea of this study is to consider geometry optics model, which can provide the approximate blurring PSF (point spread function) kernel, which varies according to the distance from X-ray tube to each pixel. The FOV (field of view) was divided into sever...

Patient education objectives are included as a strategy in every health promotion area addressed in Healthy People 2000. The likelihood of accomplishing these objectives is linked to the accuracy of the baseline estimates of practice. These estimates have most usually relied upon patient and physician reports. However, the accuracy of these reports has been infrequently studied. We analyzed aud...

deserved. Recipients who attribute the mistreatment to a noninternal cause (ie, an ineffective teacher or suboptimal learning environment) may feel guilt or humiliation but do not necessarily experience shame. Thus, the emotional outcome of the mistreatment must be analyzed to determine if particular treatment is “shaming.” The ability to receive mistreatment and not experience shame may actual...

BACKGROUND The Intensified Case Finding (ICF) tool was approved for TB screening in 2011; however there is still paucity of robust data comparing yields of the different ICF screening modalities. We compared yields of three different screening modalities for TB among Patients Living with HIV (PLHIV) in Uganda in order to inform National TB Programs on the most effective TB screening method. M...

We introduce Kloosterman polynomials over F2m , and use these polynomials to prove three identities involving Kloosterman sums over F2m .

Purpose – This paper aims to explore the prevalence rate of adolescents engaging in aggressive behaviours towards their peers using the Internet andmobile phones, while examining the duration and intensity of this cyberbullying, and to analyse differences in cyberbullying behaviours based on gender and age (academic grades). Research on cyberbullying indicates that it is a global problem that i...

UNLABELLED PATIENT SCENARIO: An adolescent female youth soccer athlete, with a previous concussion history, suffered a second concussion 4 wk ago. Her postconcussive symptoms are affecting her school performance and social and family life. CLINICAL OUTCOMES ASSESSMENT: Concussion is typically evaluated via symptoms, cognition, and balance. There is no specific patient-oriented outcomes measure ...

BACKGROUND Television (TV) viewing has been associated with obesity although the effects of specific TV content on health and other behaviours remains unknown. We examined the association between watching sport on TV, physical activity levels, and risk of obesity. METHODS We studied 6,733 (aged 64.9 ± 9.2 yrs) men and women from the English Longitudinal Study of Ageing, a prospective study of...

Background: Evidence that medical error is a systemic problem requiring systemic solutions continues to expand. Developing a “safety culture” is one potential strategy toward improving patient safety. A reliable and valid self-report measure of safety culture is needed that is both grounded in concrete behaviors and is positively related to patient safety. Objective: We sought to develop and te...
