Individual performance

In the first chapter, I have discussed the limitations of high performance liquid chromatography (HPLC) and mass spectrometry when used in isolation and how the combination of the two allows these to be overcome. In this chapter, the effect of combining the two techniques with regard to the individual performance characteristics are explored. 

Yet the reasons behind this healer s excitement are lamentable. There is a lack of interest in traditional medicine from the younger generation, and as a result there is a generational loss of traditional medicine knowledge [20]. For example, the two individuals that identified Prostratin as an antiviral have since passed away, and it is likely that an individual performing the... 

Performance criterion, ft. The quality of any potential solution, X, is determined by the average system performance achieved within the zone of the decision space identified by X, ftiX), not by the individual performance obtained at any particular point x, ftin). 

Typically, an LSMBS will require more analyses than can reasonably be conducted by a single laboratory. Therefore, the analytical workload will have to be divided, with at least two and possibly more laboratories participating. Analytical results are generally more reliable and consistent if the individuals performing the analyses... 

Individual performance is tested Problems have correct answers Projects have short time lines Constant performance feedback Courses are independent Failure is painful Statistics are not routine Team performance is essential Problems have solutions Projects can take years Feedback is much less frequent Problems require integration Failure happens Statistics are essential... 

The finger prick technique is invasive, painful, and potentially dangerous, because of the risk of infection. Also, since it is not continuous, it is not possible to predict a blood glucose pattern over the day nor the exact dose of insulin needed. In addition, depending on the training of the individual performing the test, the results are subject to inaccuracy. 

Unfortunately, despite the novelty of the above approaches none of the sensors has stood the test of time, mostly due to various practical difficulties and/or poor sensitiv-ity/selectivity. Furthermore, the lack of any published data describing the use of these sensors in any biological research applications limits any conclusion that can be made on their individual performance. 

In combinatorial protocols, n experiments are performed at the same time in the same vessel. This methodology is the most efficient in terms of time and resources, but can only be applied in discrete cases in homogeneous catalysis. Indeed, the efficiency of a catalyst can only be measured when it is submitted to the reactants. Testing a mixture of catalysts in solution would give the overall efficiency of the mixture, without any indications about individual performances. 

A qualification verification certificate should be referenced, verifying that all individuals performing the OQ protocol are qualified to perform this protocol. This may be included as part of an overall IQ/OQ protocol. 

The calibration date, the calibrator, and the next calibration date shall be recorded and displayed, or records containing such information shall be readily available for each piece of equipment requiring calibration. A designated individual(s) shall maintain a record of calibration dates and of the individual performing each calibration. 

If an individual performs both radiographic procedures (i.e., procedures without use of a protective apron) and fluoroscopic procedures i.e., procedures with the use of a protective apron) during a given monitoring period, there may be no practical way to determine precisely the relative contribution each type of procedure made to the total /fp(lO) value recorded by a personal monitor. However, occupational exposure during radiographic procedures should be very low, since the worker is at a relatively large distance from the x-ray source and most often i.e., except for use of mobile x-ray systems) in a protective cubicle. 

Working group. A working group consists of members who interact primarily to share information, best practices, or perspectives and to make decisions to help each individual perform within his or her area of responsibility. 

Calibration records The equipment identification, calibration dates, the individual performing each calibration, and the next calibration date shall be documented. These records shall be displayed on or near each piece of equipment or shah be readily available to the personnel using such equipment and to the individuals responsible for calibrating the equipment. 

The SOPs described have by no means mentioned all those required in a manufacturing plant. They do, however, satisfy basic requirements and should provide insight so that areas in the specific organization for which SOPs are needed can be identified. It should always be remembered that more than one individual must be capable of performing a given task at times he or she will be on vacation or absent because of sickness. In addition, an individual should not be relied on to perform tasks from memory, as there is no guarantee that such operations will be performed as reproducibly as may be required. Certainly no two individuals performing an operation from memory will do it identically. Written SOPs are necessary to avoid these pitfalls. Also, a written record provides a history that can be read and... 

The active participation of the entire staff in a QA program is essential. Responsibility for QA is therefore included in every employee s position description in the BOC. This emphasizes the importance of QA in the laboratory, and demonstrates an expectation of participation in the program. Individual performance standards addressing QA provide a mechanism for evaluating an employee s participation in the program, and rewards those demonstrating a positive attitude towards QA. This also helps establish positive role models for participation in the program. 

Individuals performing the studies are responsible for following the SOPs and documenting deviations from SOPs. 

A major disadvantage of manual methods is that the accuracy of each measurement relies on the individual performing the calculations and on where the tangents or baselines are drawn, which may differ from one peak to the next within an analysis. If strip-chart recorders are used, all the peaks must be contained on the chart paper. This severely limits the dynamic range of solute composition that can be analyzed. In addition, the chart speed must be fast enough so that, for measurements based on peak width, narrow peaks are wide enough for accurate measurement.
