This paper tackles the practical application of statistical tools. Chemical development is a rich area for collaboration between statisticians and chemists, but most statisticians encounter difficulties in promoting the tools to this client group. This paper, presented from a chemist's perspective, is intended to help bridge the gap between the two professions. The paper explores differences in uptake and attitudes towards adopting these techniques and suggests what has hindered or helped the process of effective application of experimental design.

Management information systems fail to support management because they are not flexible enough to keep pace with the unstructured nature of decision making processes. Observations made in four welfare management information systems suggest that computerization improves evocation—the means by which decision makers pool data from the collective memory, only to the extent that choices and the relevancy of data are predetermined. Facing rigid procedures and irresponsiveness to irregular data needs, managers of all ranks duplicate the computerized memory with manual records and files so as to retain access to their memory under their terms.  相似文献

Three male and three female raters were shown videotapes of 29 male subjects who were speaking to a silent female confederate. Raters were asked to make 10 judgments about the subjects' behavior. The subjects had been assigned to one of two expectancy conditions in which they were led to believe the drink they consumed prior to meeting the confederate contained alcohol and tonic or tonic only. Actually, half of the subjects in each expectancy condition received alcohol and half received tonic only. Judgments of the female raters viewing the videotapes were congruent with physiological measures of the subjects' anxiety. Those subjects who believed they received alcohol were perceived by female raters as more relaxed, less anxious, less inhibited, and more dominant than subjects who believed they received tonic. The actual content of the drink had no significant effects on the raters' judgements of the subjects' behavior. Male raters were unable to discriminate among the experimental conditions. Implications for possible gender of rater effects in behavioral assessment procedures as well as for the impact of beliefs on nonverbal communication are discussed.  相似文献

An inferential model which utilizes surname comparisons in inferring legitimacy status is developed and validated. Criterion validation is employed to assess the level of agreement between the inferential approach and the conventional reporting procedure. Data for the analysis are based on a sample of birth certificates contained in files of the National Center for Health Statistics for calendar year 1973. Results indicate that despite excessive error within some categories of the control variables, the inferential method is generally adequate to obtain reliable estimates of illegitimacy.  相似文献
