A study of task uncertainty associated with public accounting firm services
Relative levels of task uncertainty associated with various CPA firm services were examined in this study. Additionally, tests to determine whether systematic variation occurs at the office or at the firm level were conducted. Multiple measures of task uncertainty were developed. Multiple analysis …

The Effects of System Reliability and Task Uncertainty on Unmanned Aerial Vehicle Operator Performance under High Time Pressure
… affect operator performance. The UAS operator task differs from that of a manned aircraft pilot. An UAS operator does not get the same sensory cues as a pilot and their field of vision is significantly restricted among other limitations.</p> <p>This study examined the effects of system …

Effect of Time Pressure and Task Uncertainty on Human Operator Performance and Workload for Autonomous Aerial Vehicle Missions
… role creates a need for a shift in interface and task design in order to take advantage of the full potential of these systems. This study examined the effect of time pressure and task uncertainty have on autonomous unmanned aerial vehicle operator task performance and workload. Thirty …

Contingent factors affecting budget system usefulness: an information processing perspective
… theory of organization structure. Two sources of uncertainty -- environmental uncertainty and task uncertainty -- were viewed as forming the information processing requirements faced by the organization. In response to these requirements, organizations were viewed as adapting by altering their …

Valuing and managing brands: An internal accounting perspective. An empirical investigation of attitudes to internal brand valuation and organisational and behavioural implications associated with the way that the internal brand management accounting system is operated.
… tension in situations of high, compared to low, task uncertainty situations. 6) Reliance on a brand manager's accounting performance is positively related to brand manager performance and motivation, and negatively associated with job-related tension.

Essays On The Motivating Effects Of Goals In Accounting
… participants exerted more effort on a task when facing short goal horizons. The shorter horizons allowed workers to achieve more goals in a given time, and this motivated them. However, as uncertainty in the task was increased, effort decreased with short goal horizons. By contrast, …

Experiential and Neurobiological Influences on Economic Preferences and Risky Decision Making
… participants performing a sequential investing task. By manipulating task uncertainty, we show that pupil dilation is positively correlated with both asset price variance and regret. In addition, pupil linked arousal is positively associated with the learning rate. We conclude that the …

Passivity-Based Hands Towards General-Purpose Robotic Manipulation
… to evaluate performance in general-purpose tasks. Furthermore, this thesis explores examples of embodied intelligence and how complex behaviours can emerge with passive design, such as with: an adaptive suction cup which utilises parallel chambers for multi-modal grasping; and a passive …

Transference of efficacy beliefs and effects of self-efficacy-performance spirals at group and individual levels
… spirals. According to this model, feedback, task uncertainty and task experience are factors affecting the generation of efficacy-performance spirals. Since, among several variables, the effect of feedback on self-efficacy-performance spirals at the individual level is well established in the …
