: metadiscourse in introduction sections of applied linguistics and physics research articles: exploring variation in frequency and type
abstract in written mode of language, metadiscourse markers are used commonly to help writers in general and academic writers in particular to produce coherent and professional texts. the purpose of the present study was to compare introduction sections of applied linguistics and physics articles regarding their use of interactive and interactional metadiscourse markers based on the model pro...
15 صفحه اولHigh-pressure, synthetic loveringite-davidite and its rare earth element geochemistry
Loveringite-davidite members of the crichtonite group were synthesized at high pressure and temperature (7.5 kbar, 1000-1050 ~ from a melt of TiO2 and rare earth element (REE) enriched basaltic andesite composition. Four sets of partition coefficients for La, Sin, Ho, Lu and Sr (analogue for Eu 2+) were obtained. These show that light and heavy REE are readily accommodated, but the intermediate...
متن کاملVariation and Synthetic Speech
As high-quality synthetic speech becomes more and more of a reality, the question of how to introduce what we have learned about variation becomes a question of critical importance. If indeed variation is as important to understanding and explaining language as we have been saying it is, how should we apply our knowledge to speech generation systems? In order to approach this issue, we need to ...
متن کاملSuppressing variation in synthetic circuits
One of the challenges in engineering biological devices is to precisely control the number of parts in each cell. Automobile engineers do not worry about control mechanisms for variation in the number of wheels on a car—if an engineer designs a car with four wheels, then all the cars roll off the assembly line with four wheels. But biology is dynamic, and biological circuits change continuously...
متن کاملPoliteness and Variation in Synthetic Social Interaction
“Get lost!” or “I think you should leave now” or “Ok, perhaps I’ll see you around some other time”, humans seem to be expressing things differently in different situations based on various factors: Social relationship between the two people, urgency of an action, their personality, etc. Social interaction of synthetic agents appears believable when it has at least some characteristics of human-...
