“…www.md-journal.com Category scores were obtained by applying Hayashi's quantification theory type 2 [20][21][22] with the respondent's background as the explanatory variable and "(E) Overall grade on patient safety" as the objective variable to examine the impact of the respondent's background on patient safety culture. The range of scores defined as the difference between the maximum and minimum of the category scores obtained for each explanatory variable was calculated, [23] and the influence on patient safety culture was estimated. Hayashi's quantification theory type 2 is a linear discriminant analysis of categorical data.…”

We conducted a cross-sectional study of patient safety culture aimed at examining the factors that influence patient safety culture in university hospitals under a universal health insurance system. The Hospital Survey on Patient Safety Culture developed by the Agency for Healthcare Research and Quality was used. The survey was distributed to 1066 hospital employees, and 864 responded. The confirmatory factor analysis showed a good fit of the results to the 12-composites model. The highest positive response rates were for “(1) Teamwork within units” (81%) and “(2) Supervisor/manager expectations and actions promoting patient safety” (80%), and the lowest was for “(10) Staffing” (36%). Hayashi’s quantification theory type 2 revealed that working hours per week had the greatest negative impact on patient safety culture. Under a universal health insurance system, workload and human resources might have a significant impact on the patient safety culture.

“…Hayashi's Quantification Theory II.-HQT-II is one of four methods of quantification introduced by a Japanese statistician, Chikio Hayashi, who also coined the now widely used term "data science" in 1996. He developed his methods to deal with qualitative data, and they are widely used in Asia in many fields, such as the geologic, environmental, and medical sciences and civil engineering (Hayashi 1950;Matsuba et al 1998;Li et al 2005;Takasawa et al 2010). HQT-II aims at discrimination and classification of samples by establishing discrimination functions based on several variables of known types.…”

The classical taxonomy of fossil invertebrates is based on subjective judgments of morphology, which can cause confusion, because there are no codified standards for the classification of genera. Here, we explore the validity of the genus taxonomy of 75 species and morphospecies of the Follicucullidae, a late Paleozoic family of radiolarians, using a new method, Hayashi's quantification theory II (HQT-II), a general multivariate statistical method for categorical datasets relevant to discriminant analysis. We identify a scheme of 10 genera rather than the currently accepted 3 genera (Follicucullus, Ishigaconus, and Parafollicucullus). As HQT-II cannot incorporate stratigraphic data, a phylogenetic tree of Follicucullidae was reconstructed for 38 species using maximum parsimony. Six lineages emerged, roughly in concordance with the results of HQT-II. Combined with parsimony ancestral state reconstruction, the ancestral group of this family is Haplodiacanthus. Five other groups were discriminated, the Parafollicucullus, Curvalbaillella, Pseudoalbaillella, Longtanella, and Follicucullus–Cariver lineages. The morphological evolution of these lineages comprises a minimum essential list of eight states of four traits. HQT-II is a novel discriminant analytical multivariate method that may be of value in other taxonomic problems of paleobiology.
