Knowledge practitioner

It is important to note that the two dispersion coefficients are the product of a long history of field experiments, empirical judgments, and extrapolations of the data from those experiments. There are few knowledgeable practitioners in the dispersion modeling field who would dispute that the coefficients could easily have an inherent uncertainty of 25%. 

Herbalists also believe that combining herbs improves efficacy and reduces adverse effects. When compounded by knowledgeable practitioners, some of the remedies do make sense. The combination of Devil s claw, white willow, and tumeric, all agents with antiinflammatory effects, is rational, and quite probably effective. But combining St. John s Wort, which contains a selective serotonin reuptake inhibitor, with Ephedra, which causes increased catecholamine release, is both dangerous and ill advised. 

In a different approach. Smith and Arnold (1999) conducted a survey to determine what safety knowledge practitioners would expect in newly hired engineering graduates in the USA. The purpose of their study was to establish a baseline for a constmction site safety course content to be offered for undergraduate engineering students. Responses were received from 27 constmction firms operating predominantly in the northeastern USA. Out of 14 safely responsibility areas identified by... 

C. Daniel, App/ications of Statistics to lndustria/Experimentation, ]oE Wiley Sons, Inc., New York, 1976. This book is based on the personal experiences and insights of the author, an eminent practitioner of industrial appHcations of experimental design. It provides extensive discussions and concepts, especially in the areas of factorial and fractional factorial designs. "The book should be of use to experimenters who have some knowledge of elementary statistics and to statisticians who want simple explanations, detailed examples, and a documentation of the variety of outcomes that may be encountered." Some of the unusual features are chapters on "Sequences of fractional repHcates" and "Trend-robust plans," and sections entided, "What is the answer (what is the question )," and "Conclusions and apologies."... 

In the development of the assembly variability risks analysis, expert knowledge, data found in many engineering references and information drawn from the CSC DFA/MA practitioner s manual (CSC Manufacturing, 1995) were collated and issues related to variability converged on. Much of the knowledge for the additional assembly variability risks analysis was reviewed from the fabrication and joining data sheets called PRocess Information MAps (PRIMAs) as given in Swift and Booker (1997). 

A young scientist said, I have never seen a complex scientific area such as industrial ventilation, where so little scientific research and brain power has been applied. This is one of the major reasons activities in the industrial ventilation field at the global level were started. The young scientist was right. The challenges faced by designers and practitioners in the industrial ventilation field, compared to comfort ventilation, are much more complex. In industrial ventilation, it is essential to have an in-depth knowledge of modern computational fluid dynamics (CFD), three-dimensional heat flow, complex fluid flows, steady state and transient conditions, operator issues, contaminants inside and outside the facility, etc. 

Practitioners who design, implement, monitor, and evaluate medication therapy bear an important responsibility to their patients and society. Development of these abilities requires an integration of knowledge, skills, attitudes, and values that can be acquired only through a structured learning process that includes classroom work, independent study, hands-on practice, and, ultimately, involvement with actual patients. 

There are as yet no signs that the development of mass spectrometry is slowing down. This has consequences for the analyst. Whereas in the past the practitioner of polymer/additive analysis primarily benefited from a good knowledge of chromatography, it is now essential that such analytical scientists are conversant with current MS theory and practice. Advances in MS are due to new conceptual design, new ionisation methods (e.g. switched plasma sources) and... 

All of the science disciplines contribute to the body of information and knowledge that is used by pharmaceutical researchers, educators, and practitioners. Questions and information needs that arise within a pharmaceutical specialty will not necessarily be met by the literature associated with that specialty [13]. Researchers and academics particularly need access to a broad range of science literature. English is widely used however, the biomedical literature is and has been truly international [13]. About 86% of the current MEDLINE database is English language even though only 52% of current cited articles were published in the United States [20]. 

No work of this type could be written without the help, encouragement and support of many practitioners in the field. The authors are indebted to their various teachers (both formal and informal) over the years who instilled in them a love of knowledge, science in general, and polymers in particular. 

We will go so far as to make an analogy with Chemistry itself. The alchemists of old had an enormous empirical knowledge base, and from that could do all manner of useful things. But we do not consider alchemy a science, and it did not become a science until the underlying principles and phenomena were discovered and codified in a way that all could use. The current state of Chemometrics is more nearly akin to alchemy than Chemistry we can do all manner of useful things with it, but it is all empirical and there are still many areas where even the most expert and prominent practitioners treat it as a black box and make no attempt to understand the inner workings of that black box.
