Approximate Computing The high-performance computing systems available today are far from meeting the performance and energy efficiency targets necessary to satisfy the needs of future computing systems. With processor clock frequencies leveling-off over the past several years, the only way to achieve the expected levels of performance within the same physical size and the same or lower energy requirements is to have more processors computing in parallel. However, increasing concurrency among the processors increases interprocessor communication, which then becomes the critical bottleneck.
Introduction Perhaps the earliest use of technology in qualitative research was when researchers first used tape recorders in their field studies to record interview sessions.
In one sense this was clearly an easier way for researchers to keep a record of events and conversations, but it had two unforeseen consequences. First, it began to shift the effort of work in making a record of sessions from the researcher who traditionally took handwritten notes to others, such as secretaries and audio typists.
This separation had an impact not only on how close to or distant from the data the researcher could remain, but also on the relationship between the data and the emerging analytic ideas of the researcher.
Having a recording and a transcript meant that new ways of thinking about how the analysis developed out of the data and how the analysis was supported by the data became possible. Second, it allowed different kinds of analysis that could only be undertaken if accurate records of the speech were kept.
This made possible a focus on the small scale and minute content and characteristics of speech. It also opened up the possibilities of much larger scale studies and the use of multiple researchers and analysts.
In the 21st century, the use of new technology still raises issues like what should be analysed, how it should be analysed and in what ways the knowledge and understanding gained are different and more or less well founded than those gained in more traditional ways.
The papers in this issue address both these impacts of the technology: Most researchers recognise that in most cases, the use of new technology usually affects both. Data Gathering Audio recording is an analogue technology, as are film and traditional video.
There is a long history of their use in many areas of social and psychological research and especially in anthropology. Recent changes in this technology have taken several forms. First it has become cheaper and more widespread. This means that the technology is more available to researchers, but also that the people being researched are more used to being recorded by the technology and even familiar with using it themselves.
For example, in the case of video, people are now used to being recorded whether as part of a "holiday video" or as part of the now widespread CCTV Closed Circuit Television security systems.
They are often familiar with making their own video recordings and with "reading" the wide variety of video material they are presented with. Both the cheapness and ubiquity of the technology mean that there are new opportunities for researchers not only to record settings but also to use the technology to create new data.
Naturally, the use of such technology raises issues of interpretation, impact and validity that researchers need to deal with. However, she found that they very quickly ignored the pictures and started more general discussions about their work practices.
Consequently, she used printed versions of the photos as the basis of a group discussion amongst the researchers. Interaction patterns in task-oriented small groups discuss the use of the video analysis software, THEME, to identify communicative patterns in two distinct examples of task-oriented small group interaction.
They focused on power-related and support-related behaviour as well as verbal and nonverbal patterns in the behaviour. With the software they found two interaction patterns that it would have been hard to detect without the use of the software:International Journal of Engineering Research and Applications (IJERA) is an open access online peer reviewed international journal that publishes research.
