This paper explores how Cognitive Work Analysis (CWA) can be an effective approach for analyzing, designing, and evaluating complex sociotechnical systems such as elementary and middle school literacy support classrooms adopting new handheld technologies. CWA should be seen as an integral precursor to any design research iteration, enabling the identification of key constraints in order to desi...

Cognitive Work Analysis (CWA; Rasmussen, Pejtersen & Goodstein, 1994; Vicente, 1999) is most familiar to cognitive engineers from its successes in the area of interface design. In this report, we describe how we have used CWA in a variety of other contexts at the Defence Science and Technology Organisation (DSTO) in Australia. First, we describe the five analytic techniques of CWA, and we show ...

Cognitive Work Analysis (CWA) is gaining momentum for analyzing complex socio-technical systems but it does not yet have the specific tools and techniques that allow it to address teamwork explicitly enough to provide good guidance on how to support teams. This paper focuses on expansion of control task analysis (ConTA), the second phase of CWA, to understand the collaborative decision making o...

Diarrhea is a leading cause of death among young mammals, especially during weaning. Here, we investigated the effects of Cathelicidin-WA (CWA) on diarrhea, intestinal morphology, inflammatory responses, epithelial barrier and microbiota in the intestine of young mammals during weaning. Piglets with clinical diarrhea were selected and treated with saline (control), CWA or enrofloxacin (Enro) fo...

technology selection is an important part of management of technology. recently karsak and ahiska (2005) proposed a novel common weight multiple criteria decision making (mcdm) methodology for selection of the best advanced manufacturing technology (amt) candidates based on a number of attributes. however, amin et al. (2006), by means of a numerical example demonstrated the convergence difficul...

Formal analysis is of importance in order to increase confidence that the protocol satisfies its security requirements. In particular, the results obtained from the formal analysis of the smart card security protocols when smart cards are used as a specific type of Secure Signature Creation Devices (SSCDs) are presented. SSCDs are developed to support the EU-directive on electronic signatures. ...

Background Clot waveform analysis (CWA) based on activated partial thromboplastin time (APTT) is a useful assay for hemostasis. However, the effects of activators and phospholipid conditions CWA have not been adequately investigated. Therefore, we characterized using four different APTT reagents.

Cognitive work analysis, originally formulated for the process control domain, has seen increasing use in command and control (C2) domains. Process control applications of CWA occur in causal domains, in which the actual process and related limitations of natural laws constrain the system. However, C2 domains are intentional domains which are human-activity based, as opposed to process-control ...
