Grounded theory‖s popularity persists after three decades of broad-ranging critique. We discuss here three problematic notions – “theory,” “ground” and “discovery” – which linger in the continuing use and development of grounded theory procedures. We argue that far from providing the epistemic security promised by grounded theory, these notions – embodied in continuing reinventions of grounded ...
متن کاملSome Open Questions in the Theory of Singularities
Three approaches to a theory of equisingularity of complex analytic (or algebraic) hypersurfaces are outlined, based respectively on topology (topological equivalence of embedded varieties), differential geometry (Conditions A and B of Whitney) and algebraic geometry (the author's inductive discriminant criterion). For each of these approaches some unsolved questions and (or) conjectures are fo...
متن کاملSome Questions
These are some questions I am every interested in. Your solution to any question in this draft would be welcome. I keep updating this draft. 1. Classical recursion theory We use R to denote the partial ordering of r.e. degrees and Dn to denote the partial ordering of n-r.e. degrees. Yang and I proved thatR is not a Σ1-substructure of Dn. Question 1.1 (Khoussainov). For n > 1, is there a functio...
متن کاملSome Phonetic Structures of Chickasaw
This paper provides a quantitative phonetic study of Chickasaw, a Muskogean language spoken in Oklahoma. Basic properties such as vowel quality, voice onset time, and consonant closure duration are examined and compared with the corresponding properties in other languages of the world. We also examine quantitative properties of the typologically unusual three-way length distinction in Chickasaw...
