Data analysis in qualitative research is a creative process. As the instrument of data analysis, the researcher explores and reflects on the meaning of the data. In most qualitative traditions, the data analysis phase overlaps the data collection phase. As data analysis proceeds, the researcher moves back and forth between data analysis and data collection in order to create and explain the fin...

Twitter is a social network with over 250 million active users who collectively generate more than 500 million Tweets each day. In social sciences research, Twitter has earned the focus of extensive research largely due to its openness in sharing its public data. Twitter exposes an extensive API which can be used to collect a wealth of social data. In this chapter we will introduce the reader t...

We present an optimized layout of horn positions for the Degree Angular Scale Interferometer (DASI), which provides good coverage of the u-v plane and 3-fold symmetry. We investigate how an optimal subspace filtering analysis of a single pointing of DASI could be used to determine the anisotropies in the cosmic microwave background over a range of angular scales near 30. We discuss the compleme...
