An Expectation-Maximization approach to sensor calibration is presented and applied to three-axis-magnetometer calibration. This approach is different from the existing attitude-independent approaches mainly in how the attitude parameters in the attitude sensor measurement model are handled. The attitude-independent approaches rely on a conversion of the body and reference representations of th...

Attitude strength has been the focus of a huge volume of research in psychology and related sciences for decades. The insights offered by this literature have tremendous value for understanding attitude functioning and structure and for the effective application of the attitude concept in applied settings. This is the first Annual Review of Psychology article on the topic, and it offers a revie...

While knowledge sharing attitude represents a key factor affecting knowledge sharing behavior, the knowledge sharing attitude remains vaguely understood in the literature. Despite that attitude is a multicomponent concept, most past studies of knowledge sharing have focused on knowledge sharing attitude as a single-component construct. Thus, the structure of the knowledge sharing attitude, its ...

Adequate knowledge, positive attitude, and feeling of comfort are important factors in providing compassionate care to patients. The purpose of this study was to assess physicians’ knowledge, attitude and global comfort in caring for patients with AIDS (PWA), to determine the sociodemographic variables that could influence physicians’ attitude and global comfort, and to identify any relationshi...

Two studies were conducted to examine the impact of subjective uncertainty on conformity to group norms in the attitude-behaviour context. In both studies, subjective uncertainty was manipulated using a deliberative mindset manipulation (McGregor, Zanna, Holmes, & Spencer, 2001). In Study 1 (N=106), participants were exposed to either an attitude-congruent or an attitude-incongruent in-group no...

Although some studies have demonstrated that the indirectly measured attitude towards alcohol is related to alcohol use, this relationship has not always been confirmed. In the current study, we attempted to shed light on this issue by investigating whether the predictive validity of an indirect attitude measure is dependent upon attitude accessibility. In a sample of 88 students, the picture-p...

The ability to produce meaningful evaluations of the external world (i.e., attitudes) is critical for adaptive functioning. However, to be fully adaptive, such evaluations must be flexible enough to change when circumstances warrant. The psychological processes involved in attitude change have been the subject of intensive investigation for over 50 years. We review the major themes of this lite...

The accuracy of attitude determination plays a key role in the improvement of surveying and mapping accuracy for high-resolution remote-sensing satellites, and it is a bottleneck in large-scale satellite topographical mapping. As the on-board energy is constrained and the performance of an attitude-measurement device is limited, the attitude acquired is discretely sampled with a settled time in...

The paper explores the factors that affect employees’ attitude and behaviour towards knowledge sharing in Saudi Arabian organisations. A mixed methods approach was used to gather data through a survey and semi-structured interviews. Trust was found to have a negative relationship with knowledge sharing attitude while collaborative climate, management support, openness, and rewards were found to...

Existing position controllers for VTOL UAVs require measurements of the system attitude (orientation) for feedback. However, in practice the orientation cannot be measured directly; it is rather obtained through the use of an attitude observer relying on a set of inertial vector measurements. In this paper a new control strategy is proposed for VTOL-UAVs which avoids the direct measurement of t...
