Drawing on Walsh's (2012) idea that boosting learners' contribution and interaction can play a key role in their foreign language learning, this mixed-methods study tried to cast some light on the ways by which teachers, via their choice and use of language, create or block learners' contribution in direct interactions in the classroom. A total of 800-minute recordings of 10 teachers' talks and...

mentally ill with the creation of purpose-built asylums throughout the country. The Victorians were ambivalent in their reaction to the mentally dis turbed. Whilst they sought to segregate the insane from the rest of the population, they were also terri fied by the prospect of the wrongful confinement of sane people.2 The trial of Daniel McNaughton in 1843for the assassination of Sir Robert Pee...

Content contribution from individuals is critical to the viability of online communities. In this study we identify the factors that are associated with the quantity and the quality of content sharing in a photo sharing community, where the act of content creation is decoupled from the act of content sharing. We draw on theories of intrinsic and extrinsic motivation, and find that the prospect ...

abstract malaria is still the number one killer especially among young children and is responsible for one death per minute in the world. overall,between 250-500 million cases of the disease occur worldwide causing more than one million deaths annually about 90% of which in children under five years of age. although the spread of the disease is worldwide but it is seen mostly in tropical and su...

Nanotechnologies of the future will demand the creation of large arrays of nanoscale structures and morphologies for electronic and optoelectronic devices. One approach to the creation of such arrays is to ‘‘let nature do it’’. By depositing on each other semiconductor materials that differ slightly in lattice constant, one can use the resulting lattice strain to obtain arrays of threedimension...
