In this article, the historical use of crafts in occupational therapy for the physically disabled patient is reviewed and the results of a survey aimed at describing current craft use is presented. A questionnaire was sent to a random sample of 250 occupational therapists throughout the United States who chose physical disabilities as their specialty section. Results demonstrated that, while mo...

O way to organize workers that lies between traditional assembly lines, where workers are specialists, and craft assembly, where workers are generalists, are “bucket brigades.” We describe how one firm used bucket brigades as an intermediate strategy to migrate from craft assembly to assembly lines. The adoption of bucket brigades led to a narrowing of tasks for each worker and thus accelerated...

Self propelled models under radio control have been used for many years to assess the manoeuvring and handling of ships, and occasionally small craft. The limitations for testing small, fast craft have been linked to the low model weight required and the ability to install enough power, as well as the cost of modelling. Recent advances in motor and battery technology, the availability of model ...

In this work we propose a family of trajectory tracking controllers for marine craft in the port-Hamiltonian (pH) framework using virtual differential passivity based control (v-dPBC). Two pH models of marine craft are considered, one in a body frame and another in an inertial frame. The structure and workless forces of pH models are exploited to design two virtual control systems which are rel...

Peer-to-Peer (P2P) can support service for lots of end users with little hardware investment, which suits for the efforts to lower down the service cost for Multiplayer Online Games (MOG). In this paper, we introduce PKTown, a P2P middleware inserted into Star Craft and the network layer. PKTown captures all packets generated by Star Craft. Application Layer Multicast (ALM) is a popular techniq...

The creation of useful artefacts with rich experiential qualities required quality driven interaction designers and programmers with the ability to simultaneous problem setting and problem solving. Interaction design is a design practice that defines the appearance and function of digital artefacts. Bridging interaction design and engineering is problematic because design and engineering have d...

Disruptive technological innovations often originate from surprisingly small beginnings. Giants of the Internet age such as the omnipresent Google search engine and the Facebook social networking platform have initially been designed and developed by small and independent teams. These examples are attractive to design science researchers in information systems, who desire to deliver new and inn...

Traumatic injuries can be used as general indicators of activity patterns in past populations. This study tests the hypothesis that contemporaneous (10th-12th century) rural and urban populations in medieval Poland will have a significantly different prevalence of non-violent fractures. Traumatic injuries to the post-cranial skeleton were recorded for 180 adults from rural Giecz and for 96 adul...

Craft disciplines such as ceramics, glass, and textiles might fall into the category of applied arts, industrial arts, decorative arts, fine arts, or crafts.1 They have been understood as “medium-designated” practices, the values of which are correlated with material objects and their production (Rowley, 1997). In Finland, due to the growth of design for industrial production in the 1950s,2 the...
