Three species of trichogrammatid egg parasitoids (Trichogramma deion Pinto & Oatman, Trichogramma ostriniae Pang & Chen, and Trichogramma pretiosum Riley) (Hymenoptera: Trichogrammatidae) were evaluated under laboratory conditions as potential biological control agents for the Indianmeal moth, Plodia interpunctella (Hübner) (Lepidoptera: Pyralidae), on retail shelves. A single shelving unit was...

The parasitoid, Cotesia flavipes (Cameron) (Hymenoptera: Braconidae), was introduced for biological control of the stemborer, Chilo partellus (Swinhoe) (Lepidoptera: Crambidae), in eastern and southern African countries. The parasitoid became firmly established in Ethiopia, with varying density and distribution in various regions of the country indicating that there are factors regulating the s...

In dementia care, difficulties in conversation are linked to a number of obstacles, for which we have developed a taxonomy comprised of four categories – cognitive, physical, social and identity. This paper describes current research being undertaken to ameliorate some of these obstacles using technology, including Project CIRCA and the Nostalgia project, as well as work currently being underta...

Augmentative and Alternative Communication (AAC) systems are communication aids for people who cannot speak because of motor or cognitive impairments. We are developing AAC systems where users select information they wish to communicate, and this is expressed using an NLG system. We believe this model will work well in contexts where AAC users wish to go beyond simply making requests or answeri...

We describe the implementation of a Word Sense Disambiguation (WSD) tool in a Dutch Text-to-Pictograph translation system, which converts textual messages into sequences of pictographic images. The system is used in an online platform for Augmentative and Alternative Communication (AAC). In the original translation process, the appropriate sense of a word was not disambiguated before converting...
