This study tries to identify the determinants of user’s attitude toward apps, intention to use and continual consuming intention. This study holds the two main constructs: (1) user’s intrinsic determinantsvalue, innovativeness, gender, Well-being and superordinate influence on the attitude toward mobile apps, (2) the relation between attitude and app purchase & repurchase intention, and the aff...

This paper describes a path toward the development of theory for using a low noise high frame rate camera as a star tracker for spacecraft attitude estimation. The benefit of using a low noise high frame rate camera is that star data can be sampled at a faster rate while allowing one to measure very dim stars, increasing the number of stars available for attitude estimation. The development of ...

A GPS multi-antenna system consisting of multiple off-the-shelf GPS sensors has been successfully developed and extensively tested in operational marine environments. The advantages to use such a system are the flexibility in the selection of GPS sensors, the cost-effectiveness of the system with the emerging low-cost high performance GPS products and the increased productivity of equipment whi...

In his now-classic research on inoculation theory, McGuire (1964) demonstrated that exposing people to an initial weak counterattitudinal message could lead to enhanced resistance to a subsequent stronger counterattitudinal message. More recently, research on the valence-framing effect (Bizer & Petty, 2005) demonstrated an alternative way to make attitudes more resistant. Simply framing a perso...

Functional theories of attitudes address why people hold attitudes. The current study had two main goals: to extend the study of attitude functions, and to relate these functions to moral development. One hundred seventy-four participants filled out a revision of Herek's (1987) Attitude Functions Inventory (AFI) and a short form of Rest's (1979) Defining Issues Test (DIT). Factor analysis on th...

The stability of spacecraft attitude is studied with considering sinusoidal disturbance. A passive attitude controller without angular velocity measurement for spacecraft described by quaternion is designed. The passive controller has no information related to system parameters. So it has robustness to model error and uncertainty of model parameters. The stability of spacecraft attitude control...

Small satellites are now capable of performing missions that require accurate attitude determination and control. However, low size, power, and cost requirements limit the types of attitude sensors that can be used on a small craft, making attitude estimation difficult. In particular, star trackers—often the attitude sensors of choice for larger spacecraft—are not practical for small satellites...

It's fitting that my first contribution in the new " Attitude and Behavior " column addresses the age-old question, which comes first-attitude or behavior? Actually, the more practical question is which should be targeted for change first-attitude or behavior? Education typically addresses " attitude " or internal and subjective dimensions of people by attempting to " think people into acting d...

A novel split field of view star tracker is being developed for the EO-3 GIFTS mission (2004). The camera is designed to be autonomously self-calibrating, and capable of a rapid/reliable solution of the lost-in-space problem as well as recursive attitude estimation. Two efficient Kalman filter algorithms for attitude, camera principal point offset, and focal length estimation are developed. The...
