Critical Decision

For each quality objective you should have a plan that defines the processes involved in its achievement. Assess these processes and determine where critical decisions are made and who is assigned to make them. Audit the decisions and ascertain whether they were contrary to the objectives. A simple example is where you have an objective of decreasing dependence upon inspection. By examining corrective actions taken to prevent recurrence of nonconformities you can detect whether a person decided to increase the level of inspection in order to catch the nonconformities or considered alternatives. Any person found making such a decision has clearly not understood the quality objective.

Protocol. In 1997, prior to President Clinton s acceptance of the Kyoto Protocol, U.S. Senate Resolution 98, the Byrd-Hcgcl resolution, which was passed by a vote of ninety-five to zero, imposes specific requirements that must be met before the Kyoto Protocol can be ratified. The resolution calls for a specific timeline and commitments by developing countries to reduce greenhouse gas emissions, and evidence that adoption of the Kyoto Protocol would not result in serious harm to the U.S. economy. In addition, the Fifth Conference of the Parties (1999) failed to resolve numerous outstanding issues held over from the previous conference, and put off critical decision making until the Sixth Conference of the Parties in The Ffague, Netherlands, in November 2000.

Before starting the search for solutions, it is necessary to select among the M decision variables a subset of H variables, Xf, h- 1,..., W, which influence significantly the system performance, and thus will be used by S and included in the definition of the final set of hyperrectangles, X. For this preliminary choice of critical decision variables, other than his or her own specific process knowledge, the decisionmaker can count on a number of auxiliary techniques enumerated in Saraiva and Stephanopoulos (1992c). 

The critical decisions in the modeling problem are related to the other three elements. The space G is most often defined as the linear span of a finite number, m, of basis functions, 0 ), each parametrized by a set of unknown coefficients w according to the formula... 

The most critical decision to be made is the choice of the best solvent to facilitate extraction of the drug residue while minimizing interference. A review of available solubility, logP, and pK /pKb data for the marker residue can become an important first step in the selection of the best extraction solvents to try. A selected list of solvents from the literature methods include individual solvents (n-hexane, " dichloromethane, ethyl acetate, acetone, acetonitrile, methanol, and water ) mixtures of solvents (dichloromethane-methanol-acetic acid, isooctane-ethyl acetate, methanol-water, and acetonitrile-water ), and aqueous buffer solutions (phosphate and sodium sulfate ). Hexane is a very nonpolar solvent and could be chosen as an extraction solvent if the analyte is also very nonpolar. For example, Serrano et al used n-hexane to extract the very nonpolar polychlorinated biphenyls (PCBs) from fat, liver, and kidney of whale. One advantage of using n-hexane as an extraction solvent for fat tissue is that the fat itself will be completely dissolved, but this will necessitate an additional cleanup step to remove the substantial fat matrix. The choice of chlorinated hydrocarbons such as methylene chloride, chloroform, and carbon tetrachloride should be avoided owing to safety and environmental concerns with these solvents. Diethyl ether and ethyl acetate are other relatively nonpolar solvents that are appropriate for extraction of nonpolar analytes. Diethyl ether or ethyl acetate may also be combined with hexane (or other hydrocarbon solvent) to create an extraction solvent that has a polarity intermediate between the two solvents. For example, Gerhardt et a/. used a combination of isooctane and ethyl acetate for the extraction of several ionophores from various animal tissues. 

To prevent a possible alignment of holes in safety barriers, company C has as opposed to companies A and B, severe risk constraints present, which strictly require additional safety measures to be implemented when holes are identified in a safety barrier, as illustrated by the number of positively affected safety barriers in the other two companies. Moreover, in company C safety critical decisions are made on the highest level, creating an overview and also commitment of all employees to identify, report and reduce risks as soon and as effectively as possible. 

Relating the Time-Course of Plasma Concentrations to the Time-Course of Effect A critical decision to be made after the first human study is whether the compound s speed of onset and duration of action are likely to be consistent with the desired clinical response. Speed of onset is clearly of interest for treatments which are taken intermittently for symptoms rehef, for example, acute treatments for migraine, analgesics, or antihistamines for hay fever. Duration of action phase I is particularly important when the therapeutic effect needs to be sustained continuously, such as for anticonvulsants. The first information on the probable time course of action often comes from the plasma pharmacokinetic profile. However, it has become increasingly evident that the kinetic profile alone may be misleading, with the concentration-time and the effect-time curves being substantially different. Some reasons for this, with examples, include... 

Chemical signals associated with egg sites are probably widespread in insects, but we know much less about them than about sex attractants. These egg-site signals guide one of a female insect s critical decisions, her choice of appropriate places to lay her eggs. If larvae are to have a chance to survive, they must hatch into a suitable setting where proper nourishment is available. Not all larvae are as particular about their food as those of French truffle flies (,Suillia humilis and related species), which feed selectively on the... 

Many of the problems facing the United States and the rest of the world are probably similar to those encountered by the successful civilizations of the past. Environmental pollution, increasing population, scarcity of resources, as well as disruptions caused by weather and climate, pose significant obstacles to the health of the economy and the high standards of living. Solutions to these problems may lie in the development of new and sophisticated technology, but the dilemmas faced by people of the past, and their successes and failures, could also play an important role in the critical decisions that people of today and tomorrow must make. 

Do not allow critical decisions to be made, or even approved if you can avoid it, by people higher up who do not appreciate what you are attempting or the issue involved.

Although not all cell death involves mitochondrial dysfunction, it often does. The various cellular changes and sequelae and effects on and changes in the mitochondria have been described above and the critical "decision points" between recovery, necrosis, and apoptosis have been outlined. What then occurs in the orderly cell death process of apoptosis ... 

Add to this mix the conspicuous failure of recent memory to keep dream data in mind for more than a very few minutes and we can consider one of the great dream mysteries (amnesia) to be tentatively solved it is the joint product of the global aminergic demodulation that affects the entire brain and the more local disenablement of the dedicated circuitry of the dorsolateral prefrontal cortex that, in waking, allows us to be critical, decisive, and executive.
