A new spacecraft attitude estimation approach using particle filtering is derived. Based on sequential Monte Carlo simulation, the particle filter approximately represents the probability distribution of the state vector with random samples. The filter formulation is based on the star camera measurements using a gyro-based or attitude dynamics-based model for attitude propagation. Modified Rodr...

BACKGROUND In medical practice, the dissatisfaction of patients about medical decisions made by doctors is often regarded as the fuse of doctor-patient conflict. However, a few studies have looked at why there are such dissatisfactions. OBJECTIVES This experimental study aimed to explore the discrepancy between attitude and behavior within medical situations and its interaction with framing d...

Gordon Allport (1954) has described the attitude concept as "the primary building stone in the edifice of social psychology [p. 45]," and the extensive attitude literature in the past 20 years supports this contention. Stimulated primarily by the cognitive consistency theories, thousands of pages have been written recently on attitude formation and change. One possible reason for the popularity...

In two studies, we investigated the roles of explicit memory and attentional resources in the process of behavior-induced attitude change. Although most theories of attitude change (cognitive dissonance and self-perception theories) assume an important role for both mechanisms, we propose that behavior-induced attitude change can be a relatively automatic process that does not require explicit ...

BACKGROUND With the increase in prevalence of Middle East Respiratory Syndrome (MERS), healthcare workers (HCWs) are at risk of acquiring and subsequently transmitting this lethal virus. In view of this, HCWs were evaluated for their knowledge of and attitude towards MERS in Saudi Arabia. METHODS A cross sectional study was performed in two hospitals of Qassim region in Saudi Arabia. A total ...

This research paper analyzes the impact of information and network characteristics on the affective, cognitive, and behavioral attitude towards information overload (IO) on Facebook. By using an information overload model and the data of 300 active Facebook users it can be shown that the various categories of attitude are influenced by different factors. The level of determination of the behavi...

Attitude Representation Theory (ART) holds that attitude-relevant responses are informed by mental representations of the attitude object, which include the individual's actions toward that object. Action Identification Theory (AIT) holds that the same action can be identified at multiple levels. Individuals who identify their actions at lower levels have less flexibility in how they perform th...

Users’ attitudes depict one of the main determinants, why individuals use information systems. However, in the basic theoretical understanding of social psychology research attitude could be shaped in two different ways; attitude formation and attitude change. Within this paper, both attitude research streams are theoretically reflected as well as observed in IT adoption literature using data o...

MAIN PROBLEM There is an increasing presence of a population of British and Irish origin in southeastern Spain. HYPOTHESIS this population native from countries with higher rates of living kidney donation than Spain will be very much in favour of related living kidney donation. OBJECTIVE to analyse the attitude of this population subgroup towards living kidney donation. METHODS Between No...
