The Multitasking Myth (Ashgate Studies in Human Factors for by Loukia D. Loukopoulos

By Loukia D. Loukopoulos

Regardless of turning out to be trouble with the consequences of concurrent job calls for on human functionality, and study demonstrating that those calls for are linked to vulnerability to errors, to this point there was in basic terms restricted study into the character and diversity of concurrent job calls for in real-world settings. This publication offers a suite of NASA reviews that symbolize the character of concurrent activity calls for confronting airline flight crews in regimen operations, rather than emergency occasions. The authors learn those calls for in mild of what's identified approximately cognitive techniques, relatively these of consciousness and reminiscence, with the focal point upon inadvertent omissions of meant activities by means of expert pilots. The experiences said in the ebook hired numerous detailed yet complementary equipment: ethnographic observations, research of incident reviews submitted via pilots, and cognitive job research. They confirmed that concurrent job administration includes a collection of concerns special from (though regarding) psychological workload, a space that has been studied widely via human elements researchers for greater than 30 years. This ebook can be of direct relevance to aviation psychologists and to these occupied with aviation education and operations. it is going to additionally curiosity participants in any area that includes concurrent job calls for, for instance the paintings of emergency room clinical groups. moreover, the countermeasures awarded within the ultimate bankruptcy to lessen vulnerability to blunders linked to concurrent activity calls for can effectively be tailored to paintings in different domain names.

Mechanics of materials and interfaces: the disturbed state concept

The disturbed kingdom thought (DSC) is a unified, constitutive modelling process for engineering fabrics that permits for elastic, plastic, and creep lines, microcracking and fracturing, stiffening or therapeutic, all inside a unmarried, hierarchical framework. Its features move way past different to be had fabric types but result in major simplifications for functional purposes.

Gas Turbine Diagnostics: Signal Processing and Fault Isolation

Primary for strength new release, fuel turbine engines are at risk of faults because of the harsh operating setting. so much engine difficulties are preceded through a pointy switch in dimension deviations in comparison to a baseline engine, however the development facts of those deviations over the years are infected with noise and non-Gaussian outliers.

Example text

The other approach is “bottom-up”, relying on noticing cues or being reminded of one task by the actions of another task. 18 The Multitasking Myth An order for an IV bag to contain, among other things, sodium chloride was put through to the pharmacy. The technician started preparing the bag but was asked to assist another technician as she was about to add sodium from a multi-dose vial from which some amount of sodium had already been removed. She responded to the unexpected interruption by stepping away from her primary task of preparing the solution for the IV bag.

Some of these items, such as checking the flight controls and the stabilizer trim, are simple and take only a few seconds to complete. Other items involve multiple steps. For example, the first officer may be required to use the final weight information to perform performance calculations (from performance cards or using a special, portable computer, if available) to finish programming the FMC and to set the airspeed “bugs” (reminders of critical airspeeds on the airspeed indicators). The captain is then expected to check the first officer’s data entries in the FMC.

Reducing task demands Individuals may respond to overwhelming concurrent task demands by lowering criteria for quality, accuracy or completeness of some task elements or by eliminating some tasks altogether. If this is done strategically rather than reactively, it can be an effective approach to dealing with the overall situation by focusing on the most critical aspects of the situation. Individuals skilled in a work domain usually do not simply react to each task demand as it arises, but rather try to manage the combination of task demands to achieve overarching goals (Huey and Wickens, 1993; Raby and Wickens, 1994).
