Confidence building techniques

If test results are suspect and the problem cannot be readily identified, it is helpful to have a methodical approach to help identify the problem. Checklist 9.3 is offered as a starter kit. Consideration of the items on the list could also be used as a form of periodic preventive maintenance. If a working detector is available, use the detector and Checklist 10.2 (Confidence Building Techniques). 

We can conclude, because this 95% confidence interval does not contain 0, that 2 is statistically significant, but with a slope so slight that it has no practical significance. We return to this problem in Chapter 10, which deals with model-building techniques. 

Independent Verification of Test Station Performance We want an independent and direct way to verily that all is well - to demonstrate that the irradiance calculated is actually present, or to measure directly the extent to which the actual irradiance differs from the value calculated. The techniques used vary from one laboratory to another and are not documented in the literature or in government standards. The method described here is a series of confidence-building measurements. 

Classic parameter estimation techniques involve using experimental data to estimate all parameters at once. This allows an estimate of central tendency and a confidence interval for each parameter, but it also allows determination of a matrix of covariances between parameters. To determine parameters and confidence intervals at some level, the requirements for data increase more than proportionally with the number of parameters in the model. Above some number of parameters, simultaneous estimation becomes impractical, and the experiments required to generate the data become impossible or unethical. For models at this level of complexity parameters and covariances can be estimated for each subsection of the model. This assumes that the covariance between parameters in different subsections is zero. This is unsatisfactory to some practitioners, and this (and the complexity of such models and the difficulty and cost of building them) has been a criticism of highly parameterized PBPK and PBPD models. An alternate view assumes that decisions will be made that should be informed by as much information about the system as possible, that the assumption of zero covariance between parameters in differ-... 

A word of warning for young perfumers One of the most difficult things for students is to sustain enthusiasm and patience over what is inevitably a long and difficult period of study. The work is both introspective and competitive. All too often students may be faced with disappointment after months of work. Self-confidence can easily be destroyed, particularly when a student is allowed to charge ahead without building up the solid foundation in olfactory memory and perfumery technique on which success is based. If a perfumer ceases to enjoy his or her work, and every new project carries with it the threat of failure rather than the hope of success, the most likely cause lies in the insecurity of the technique. 

Healthcare providers, as well as local officials, are concerned about the spread of contamination. The procedure for decontamination of litter patients can be found in Appendix E of U.S. Army Field Manual 8-10-4, Medical Platoon Leaders Handbook Tactics, Techniques and Procedures.8 The IRF will decontaminate patients and pass them across a hotline to the Medical Response Team (MRT). At that point the casualty should be completely clean. Civilian officials may require a casualty certified clean before moving the patient off the military installation. This requirement may be avoided through adequate coordination and training prior to an exercise or an actual chemical accident or incident. Building confidence in the civilian sector through education and communication is essential in providing a rapid and adequate medical response. 

The following techniques of static analysis may be used to build confidence in the correctness of the source code ... 

However, in this case it is also possible to gain fnrther confidence with regards to the data used for QRA. The use of sensitivity analyses to identify the most critical data items, focused data searching and checking, use of multiple, independent data sources, comparison of model prediction with real life data (base-lining) are all techniques that should be used in support of building confidence in the modelling results. 

Assessment for gratification, which uses gamihcation techniques of continual feedback to build confidence and competence in the student. The use of gamification will enhance the validation of learning. For example, international education company Kaplan has developed a gamification platform which, it says, can boost student grades by 9 %. 

The Model of Motivational Design. In 1983, Keller outlined four components of motivation with respect to learning environments interest, relevance, expectancy and satisfaction. Upon these four components Keller and Kopp (1987) build a model of motivational design. Based on their model it is suggested that attention, relevance, confidence, and satisfaction (ARCS) should be promoted in the learners in order to enhance their motivation. The ARCS-model sums up potential instructional techniques in the four domains that can be used and combined for promoting and sustaining motivation in teaching. The domains in the ARCS-model are ... 

As a means of monitoring gas compositions, some independent verification of the performance of PTR-MS would help to build confidence in the technique. Such verification smdies have been carried out and involve comparisons with other gas analysis techniques, particularly gas chromatography (GC). It is important to recognize at the outset that PTR-MS and GC techniques will not always agree, since PTR-MS using a mass spectrometer may not be able to separate compounds with the same nominal mass, whereas GC-MS almost always can because of the additional discrimination provided by compound separation on the chromatographic column. An additional complication is that fragment ions from... 

In the following case studies, the sample preparation, data collection and data analysis procedures are described in a stepwise, in-depth fashion. The presented protocols were adapted to the equipment and experience available to the author and may not necessarily represent the best available practise for other laboratories. QPA of cements, hydrated cements in particular, cannot be used, as yet, as an operator independent black box characterisation technique. Considerable time and effort should be spent on know-how buildup of operators and analysts. Cross-checking with other characterisation techniques is paramount in building confidence in the analysis procedure and further optimising measurement and analysis protocols.
