Cognitive Work Analysis (CWA) is a methodology for analyzing complex socio-technical systems. It aims to structure system information in a manner that is meaningful for human control and interaction. The Abstraction Decomposition Space (ADS) in an important tool used during the first phase of CWA to describe the work domain. In this paper we create an ADS for a Semiconductor Fabrication Plant (...

We explore the social and technical design issues involved in tracking the effectiveness of educational and therapeutic interventions for children with autism (CWA). Automated capture can be applied in a variety of settings to provide a means of keeping valuable records of interventions. We present the findings from qualitative studies and the designs of capture prototypes. These experiences le...

In many data-centric semantic web applications, it is desirable to use OWL to encode the Integrity Constraints (IC) that must be satisfied by instance data. However, challenges arise due to the Open World Assumption (OWA) and the lack of a Unique Name Assumption (UNA) in OWL’s standard semantics. In particular, conditions that trigger constraint violations in systems using the ClosedWorld Assum...

Using low-level computational modelling to predict solution state association constants and binding modes for the identification of appropriate CWA simulants.

Cognitive work analysis (CWA) is frequently advocated as an approach for the analysis of complex socio-technical systems. Much of the current CWA literature within the military domain pays particular attention to its initial phases; work domain analysis and contextual task analysis. Comparably, the analysis of the social and organisational constraints receives much less attention. Through the s...

We investigated ability to understand goals and attribute intentions in the context of two imitation studies in low-functioning, nonverbal children with autism (L-F CWA), a population that is rarely targeted by research in the domain. Down syndrome children (DSC) and typically developing children (TDC) were recruited to form matched comparison groups. In the two sets of simple action demonstrat...

Delayed neurotoxic complications of chemical warfare agents (CWA), such as sulphur mustard (SM) and tabun, in human beings have not been reported in detail. We thus aimed to investigate possible neurotoxic complications of these agents in Iranian veterans 22-27 years after exposure. After co-ordination with the veteran foundation and obtaining the approval of the medical research ethics committ...

The Closed-World Assumption (CWA) on databases expresses that an atom not in the database is false. A more appropriate assumption for databases that are sound but partially incomplete, is the Local ClosedWorld Assumption (LCWA), which is a local form of the CWA, expressing that the database is complete in a certain area, called the ‘window of expertise’. Databases consisting of a standard datab...

Enterprise/Corporate ontologies are specifications of information of business enterprises. Semantic peculiarities of ASP, like the Closed World Assumption (CWA) and the Unique Name Assumption (UNA), are more appropriate than OWL assumptions for enterprise ontologies, also because these ontologies often are the evolution of relational databases, where both CWA and UNA are adopted. In this paper ...

An exact solution of the homogeneous wave equation which was found previously is treated from the point of view of the continuous wavelet analysis (CWA). Time being a fixed parameter the solution yields a new multidimensional mother wavelet for the CWA. Both the wavelet and its Fourier transform are given with explicit formulas and are exponentially localized. The wavelet is directional. The wi...
