Methods. A cross-sectional questionnaire study was carried out among 2,789 students in 19 high schools in Kampala District, Uganda, in 2002. In each school, three classes fromSeniorOne to Senior Three (average student age, 13 to 15 years, respectively) were randomly selected. All students who consented to participate in the study filled out a questionnaire consisting of 58 questions, with core ...

BACKGROUND Domestic violence (DV) is a serious problem all over the world which had been extended to boundaries of countries, economical, cultural and racial classes. 10-69 percent of women are exposed to physical, sexual and emotional violence which has numerous physical and emotional consequences. Therefore, males' attitude towards women is one of the strongest predicting factors of violence ...

We present and test a formal framework for expressing the idea that taking account of the multiple meanings conveyed by natural language may help economists to better understand the impact of pre-play free-form communication. We model coordination games where each player simultaneously requests others to take a particular action. We assume requests include two independent features: the desired ...

In this paper, a star tracker attitude estimation procedure with increased robustness and efficiency, using the AIM (Attitude Estimation using optimal Image Matching) algorithm, is presented and validated. The unique approach of the AIM algorithm allows us to introduce a reliable quality check which can be efficiently calculated. Unlike existing validation methods, this quality check not only d...

This survey of attitude theory and research published between 1996 and 1999 covers the conceptualization of attitude, attitude formation and activation, attitude structure and function, and the attitude-behavior relation. Research regarding the expectancy-value model of attitude is considered, as are the roles of accessible beliefs and affective versus cognitive processes in the formation of at...

One of the key concepts in the research on political attitudes is attitude strength. Strong attitudes are durable and impactful, while weak attitudes are fluctuating and inconsequential. Recently, the Causal Attitude Network (CAN) model was proposed as a comprehensive measurement model of attitudes. In this model, attitudes are conceptualized as networks of causally connected evaluative reactio...

The Unaided Single Frequency/Single Epoch Global Navigation Satellite System (SF/SE GNSS) model is the most challenging scenario for ambiguity resolution in the GNSS attitude determination application. To improve the performance of SF/SE-GNSS ambiguity resolution without excessive cost, the Micro-Electro-Mechanical System Inertial Measurement Unit (MEMS-IMU) is a proper choice for the auxiliary...

This paper describes a quaternion implementation of an Unscented Kalman Filter for attitude estimation on CubeSats using measurements of a sun vector, a magnetic field vector and angular velocity. For faster convergence of the attitude estimate, a SVD-method solving Wahba’s problem has been proposed, which provides an initial attitude estimate. Using unit quaternions provides a singularity free...

OBJECTIVE To examine the relationship of psychosocial stress and attitude toward illness to psychological adjustment among youth with chronic arthritis. METHODS Seventy-five youths with chronic arthritis aged 8-18 years were administered a semi-structured interview assessing illness-related and nonillness-related stressors in important life domains. Children also completed measures of attitud...
