  • This is an exciting time for professionals associated with physical activity and the health professions. We have seen a substantial increase in the amount and type of research being conducted. Qualitative research has grown in popularity and has gained respect as a viable method of answering important research questions. Despite its broad appeal and inclusion in many disciplines, however, qualitative research often has an ethereal or mystical feel to it, particularly for those practitioners with strong roots in physical activity and the health professions.

  • The first edition of this text was written in the early 1990s. Since then, the field of clinical research methods has continued to develop rapidly, and this second edition has been extensively updated to reflect these developments. We have also tried to make the whole book more user friendly, both in layout and in content. All chapters now have summaries and boxes highlighting the key points, and we have provided many more illustrative examples. The biggest area of change is in our treatment of qualitative methods.

  • As currently taught, the introductory course in analytical chemistry emphasizes quantitative (and sometimes qualitative) methods of analysis coupled with a heavy dose of equilibrium chemistry. Analytical chemistry, however, is more than equilibrium chemistry and a collection of analytical methods; it is an approach to solving chemical problems. Although discussing different methods is important, that discussion should not come at the expense of other equally important topics.

  • When I wrote my first book, Qualitative Choice Analysis, in the mid1980s, the field had reached a critical juncture. The breakthrough concepts that defined the field had been made. The basic models – mainly logit and nested logit – had been introduced, and the statistical and economic properties of these models had been derived. Applications had proven successful in many different areas, including transportation, energy, housing, and marketing – to name only a few. The field is at a similar juncture today for a new generation of procedures.

  • This paper presents methods for a qualitative, unbiased comparison of lexical association measures and the results we have obtained for adjective-noun pairs and preposition-noun-verb triples extracted from German corpora. In our approach, we compare the entire list of candidates, sorted according to the particular measures, to a reference set of manually identified “true positives”. We also show how estimates for the very large number of hapaxlegomena and double occurrences can be inferred from random samples. ...
