Goals success

In addition to established need, effectiveness of approach, and widely shared goals, successful advocacy for mental health programs in schools requires collaboration between the mental health and the education fields. Mental health advocates must expand their efforts beyond traditional mental health coalitions to include a broad-based constituency in order to secure buy-in outside of the mental health field. Unfortunately, too many advocacy efforts have been driven by the mental health community in an effort to force services on reluctant school systems. Such efforts are almost certain to fail since policymakers will automatically look to education advocates to determine priorities for school funding and new programs. The best advocacy efforts, as the following case studies demonstrate, are the product of communitywide coalitions and careful collaboration between multiple constituencies. 

Surface science has tlirived in recent years primarily because of its success at providing answers to frmdamental questions. One objective of such studies is to elucidate the basic mechanisms that control surface reactions. For example, a goal could be to detennine if CO dissociation occurs prior to oxidation over Pt catalysts. A second objective is then to extrapolate this microscopic view of surface reactions to the... 

Convergence limit and Iteration limit specify th e precision of the cal-ciilation. Convergence limit refers to the dilTereiice in energy (in kcal/mol) between two successive SCE cycles. Iteration limit specifies the maximum number of cycles allowed to reach that goal. 

FoUowiag Monsanto s success, several companies produced membrane systems to treat natural gas streams, particularly the separation of carbon dioxide from methane. The goal is to produce a stream containing less than 2% carbon dioxide to be sent to the national pipeline and a permeate enriched ia carbon dioxide to be flared or reinjected into the ground. CeUulose acetate is the most widely used membrane material for this separation, but because its carbon dioxide—methane selectivity is only 15—20, two-stage systems are often required to achieve a sufficient separation. The membrane process is generally best suited to relatively small streams, but the economics have slowly improved over the years and more than 100 natural gas treatment plants have been installed. 

The development of fiber optics technology, user-friendly displays, and enhanced data presentation capabihties have made on-line analysis acceptable within the plant manufactuting environment. However, it is apparent that a barrier stiU exists to some extent within many organizations between the process control engineers, the plant operations department, and the analytical function, and proper sampling is stiU the key to successful process analytical chemistry. The ultimate goal is not to handle the sample at ah. 

Goal Tar. In roofing, coal tar is used as mopping bitumen in between 15 and 20% of the BUR roofs installed. Coal-tar pitch and asphalt are considered incompatible and should not be mixed. If mixed, an oily exudate is formed that plasticizes the bitumen, and the mixture remains soft and does not weather well. For this reason, if coal tar is used in BUR systems the felts must be coal-tar saturated. There has been some success using asphalt-coated fiber-glass mat felts with coal-tar pitch. However, this has only been done for a limited number of years so the actual compatibiHty is not fully known. 

Discussion with operators provide substantial insight. The purpose of the discussion should be to develop an understanding of operators perspec tives of the unit, their foci for the operation, and their decision sequence in response to deviations and off-specification products. Two additional, albeit nontechnical, goals of this discussion are to establish rapport with the operators and to learn their language. The operators will ultimately be required to implement recommendations developed by analysts. Their confidence is essential to increase the likehhood of success. The following topics should be included in the discussion. 

Motivation Unit tests require a substantial investment in time and resources to complete successfully. This is the case whether the test is a straightforward analysis of pump performance or a complex analysis of an integrated reactor and separation train. The uncertainties in the measurements, the likelihood that different underlying problems lead to the same symptoms, and the multiple interpretations of unit performance are barriers against accurate understanding of the unit operation. The goal of any unit test should be to maximize the success (i.e., to describe accurately unit performance) while minimizing the resources necessary to arrive at the description and the subsequent recommendations. The number of measurements and the number of trials should be selected so that they are minimized. 

Recommendation When all measurements were recorded by hand, operators and engineers could use their judgment concerning their validity. Now with most acqmred automatically in enormous numbers, the measurements need to be examined automatically. The goal continues to be to detect correctly the presence or absence of gross errors and isolate which measurements contain those errors. Each of the tests has limitations. The hterature indicates that the measurement test or a composite test where measurements are sequentially added to the measurement set are the most powerful, but their success is limited. If automatic analysis is required, the composite measurement test is the most direct to isolation-specific measurements with gross error. 

Depending upon why a company chose to let a toll, the ability to scale up production may be an important factor. If a toll project was designed to meet a specific, short-term need for a known quantity of material, scale-up capability may not be an issue. However if the goal was to develop a wider market and eventually increase production, a small toller that meets all other criteria for selection could be excluded based upon this factor. Planning for success is essential.
