The Relationship

The concept of legitimate culture plays a crucial role in the study of the relationship between the differentiation of tastes and the reproduction of social inequalities. Nevertheless, the actual role of legitimate culture in present society is often disputed in light of a supposed crumbling of the privileged structure of the fine arts. Meanwhile, the existing practice of survey research often neglects this institutional dimension of the legitimisation of taste and researchers often withdraw from attempts to develop an empirically-based scale to measure the legitimacy of taste. The aim of this paper is to develop a method of measurement of cultural capital which is based on empirical evaluation of the legitimacy of respondents’ taste. Specifically, this measurement links responses to open-ended questions about favourite cultural goods with institutionalized critical ratings. The particular focus is to answer how this methodologically innovative approach relates to prevalent instruments for measurement of cultural capital (highbrow culture attendance, educational credentials) and how it could inform the study of the change of legitimate culture. The study uses data from a survey of Czech youth cultural consumption (N=524). The results show close ties between the institutional measurement of cultural capital and the Bourdieusian application of Multiple Correspondence Analysis as a mean to identify significant cultural differences. While the feasibility of institutional measurement of cultural capital in survey data could be disputed, it is a useful tool to advance our understanding of how legitimate culture operates in present society.

Multiple Task

Uninhabited aerial vehicles are aircraft without the onboard presence of pilot or aircrew. Even though the human is removed from the direct control of the aircraft, the human is typically involved in the process as a supervisor in a multiple task telerobotics control system. The supervisor must receive the appropriate information for efficient decision making and input the information required to augment the autonomous control of the vehicle as necessary. This article presents an approach that applies human operator modeling methods to perform semiotic analysis and identifies the content and form of the information required for effective supervisory control. This paper also outlines a computational modeling and simulation architecture that supports concurrent multi-user connectivity and reconfigurable user interfaces. The potential utilization of this architecture to systematically evaluate interface concepts and the role of automation in these systems is also described. Finally, an empirical evaluation is described that benchmarks the effectiveness of the architecture.Human-Integrated Supervisory Control of Uninhabited Combat Aerial Vehicles.

Purpose This study aims to explore the factors influencing the intention to use e-democracy. The literature depicted conflicting results regarding such domain and especially in the Middle East, where the authors aim at establishing a solid view of the discipline. Design/methodology/approach A research model was developed based on the theory of planned behavior, technology acceptance model and unified theory for acceptance and use of technology-2. The model hypothesized that perceived public value (PPV), ease of use and enjoyment are major antecedents of attitudes, and subjective norms (SNs), perceived behavioral control (PBC) and attitudes are significant predictors of behavioral intentions. A quantitative cross-sectional design was used. A questionnaire was used to explore Jordanian citizens’ perceptions regarding the research model constructs. A sample of 302 Jordanian citizens filled the surveys based on their awareness of e-democracy concepts and their willingness to participate in the study. This study uses the structural equation modeling approach with partial least square as an analysis method. Findings Findings indicated that PPV, perceived ease of use and enjoyment jointly determine the attitudes of citizens toward e-democracy. Results also suggest that attitudes, PBC and SNs have a significant effect on citizen’s intention to use e-democracy. Finally, this research supported the role of enjoyment as the most significant determinant of citizen’s attitude toward using e-democracy. Research limitations/implications This study is limited by its small sample size and newly developed Arabic instrument. Still, results imply that more research is needed to replicate and validate the instrument and support the role of the selected research constructs. Public institutions are required to make e-democracy applications enjoyable and easy to use. They also need to demonstrate its value to the public. Originality/value To the best of the authors’ knowledge, this study is one of the few studies to explore e-democracy and the first to conduct an empirical study (survey-based) in Jordan. The foundation of the study depended on three robust theories in the technology adoption theories.
