Additional Positive Outcomes

Although reviewing OSHA 200 entries is a good tool for auditing a safety and health program, it is only one of many tools that can be used. Such an approach takes only a retroactive look at programs once a problem has occurred. Ideally, a company should try to be proactive in its approach.

Additional positive outcomes result from such well-planned field trips, such as the possibility to have a hands-on experience with the unique technologies, scales and challenges related to a specific geotechnical project to serve as a basis for discussion after student s presentations and to serve as a basis for a related term-project that involves real parameters from geotechnical materials found at the site. 

Delayed Outcomes. We often create safety award programs to encourage employees to behave safely. The awards usually provide additional positive outcomes for not getting hurt but are too delayed to be effective consequences. We discussed problems with such programs earlier, yet such programs can be an effective component of a safety process. Figure 21.6 displays a more complete diagram that includes both consequences and outcomes. 

Cellular therapy is the replacement of lost or dysfunctional tissues with new ones. Various cell types have been evaluated and considered for therapy. In the CNS, fetal neuronal tissue has been particularly evaluated for its merit in treating neurological diseases and injuries [1]. While numerous experimental and clinical transplantation studies showed that fetal neuronal transplants improve functional deficits in models of CNS diseases [2-5], others reported less positive outcomes [6, 7]. In addition, the rate of survival of fetal neuronal cells transplanted into the adult brain is relatively low, requiring large quantities of tissue, generally from several fetuses, for therapy. Researchers are looking at other opportunities for cellular therapy, particularly in the CNS. 

In summary, the only direct evidence against the existence of a preferred frame E is the interpretation of Michelson-Morley experiments as being a nullresult. To put it mildly, this evidence is fairly weak. On the contrary, there is mounting evidence for the existence of local anisotropies [49,59,60], which can be interpreted as motion of the earth relative to E. Additionally, a replication of Faraday induction experiments with a rotating permanent magnet yielded a positive outcome [61]. Such results may be interpreted as an indication of the existence of absolute motion, and hence of E. As usual, the final referee will be empirical evidence. Hence, there is a pressing need to carry out new... 

An amalgamation of these definitions may provide the best explanation of the concept of quality in health care. Each provides additional insight into quality, what we can expect from quality, and how quality can be perceived. Webster s definition supports the idea that quality is a continuum of excellence or the lack thereof. From the Office of Technology Assessment definition it can be said that in medical care, quality can be measured and used to evaluate the care delivered by health care providers. This definition also implies that the care offered to patients should increase the probability of positive outcomes (e.g., getting rid of an infection) and decrease negative outcomes of care (e.g.,... 

In various settings such as Veterans Administration outpatient clinics, Kaiser Permanente outpatient services, hospital-based outpatient clinics, physician offices, and communify pharmacies, pharmacists have been successfully managing patients warfarin therapy. ° Research demonstrates the positive outcomes associated with, and the cost-effectiveness of, pharmacist-run warfarin clinics.In addition, with over 60,000 pharmacies across the U.S., pharmacists are readily available within most communities. ... 

It should be apparent that the textbook example of Edman analysis of a pure protein sample with an umnodified N-terminus is often not attainable without additional effort. StiU, combining an investigator s expertise in sample purification with the expertise of personnel in sequencing laboratories should result in positive outcomes from this technology at very low levels of sample. 

Health outcomes are the end result of a medical intervention. They represent what happened to the patient. Being cured of an illness is an outcome, as is death due to an illness (not all outcomes are positive). The simplest outcome evaluation would characterize people as being alive or dead. This gross distinction tells very little about the current functional status of the patient. Being alive but relying on a respirator to breathe is very different from being alive and fully functional. Additionally, intermediate outcomes (e.g. alleviation of pain or other symptoms of arthritis) are sometimes as important an outcome as the final outcome. 

Part of the issue is that risk estimates are related to factors other than likeUhood, such as catastrophic potential, degree of control, or familiarity (Lichtenstein et rd. 1978 Slovic 1978 1987 Lehto et al. 1994). Weber (1994) provides additional evidence that subjective probabilities are related to factors other than uncertainty and argues that people will overestimate the chance of highly positive outcome because of their desire to obtain it. Weber also argues that people will overestimate the chance of a highly undesirable outcome because of their fear of receiving it. Traditional methods of decision analysis separately elicit and then recombine subjective probabilities with utilities, as discussed earlier, and assume that subjective probabilities are independent of consequences. A finding of dependency therefore casts serious doubt upon the normative vahdity of this commonly accepted approach. 

Positive outcomes from the addition of a plasticizer into PLA are the increase in the environmental degradability at the end-of-life treatments. In fact, the slow degradation rate of neat PLA is often considered to be a major drawback for biomedical applications, leading to long in vivo life-time, which could be up to years in some cases. Solutions to increase the abiotic degradation rate in biomedical applications could be an inspiration to optimize the degradation of PLA in other applications, such as food packaging. 

Two additional tests, the red blood cell phototoxicity test (RBC PT) (Pape et al., 1994) and the Human 3-D Skin Model In Vitro phototoxicity test (H3D PT) (Roguet et al., 1994 Bernard et al, 1999 Liebsch et al, 1999 Jones et al, 2003), are regarded useful and important adjunct tests to overcome some limitations of the 3T3-NRU-PT, like the fairly low UVB tolerance of 3T3 fibroblasts. Moreover, the RBC PT enables evaluation of the phototoxic mechanisms involved (Okamoto et al, 1999) and the H3D PT model is qualified as an adjunct test to further investigate chemicals with (probably false) positive outcomes in the 3T3 NRU PT. 

Another common reaction is the chlorination of alkenes to give 1,2-dihaloalka-nes. Patell et al. reported that the addition of chlorine to ethene in acidic chloroalu-minate(III) ionic liquids gave 1,2-dichloroethane [68]. Under these conditions, the imidazole ring of imidazolium ionic liquid is chlorinated. Initially, the chlorination occurs at the 4- and 5-positions of the imidazole ring, and is followed by much slower chlorination at the 2-position. This does not affect the outcome of the alkene chlorination reaction and it was found that the chlorinated imidazolium ionic liquids are excellent catalysts for the reaction (Scheme 5.1-39). 

In contrast to the results obtained with the jS-alkoxy-a-alkyl-y-lactol 16 (vide supra), a chelation-directed, anti-Cram selective nucleophilic addition to the a-methyl-y-lactol 1 was not only observed with methyllithium and methylmagnesium bromide but also with (triisopropoxy)methyl-titanium72. In fact, the highest diastereoselectivity (> 98 % de) was observed with the titanium reagent in dichloromethane as reaction solvent. A seven-membered chelate 3 with the a-methyl substituent in a pscudoequatorial position has been postulated in order to explain the stereochemical outcome. 

Kinetically controlled 1,4-additions of 2-propenylsilanes to acyclic enones bearing a benzyloxy group in the 4-position proceeded with moderate stereoselectivity using titanium(IV) chloride as the preferred Lewis acid. The stereochemical outcome was dependent on the geometry of the enone used26. 

An interesting parallel was found while the microwave-enhanced Heck reaction was explored on the C-3 position of the pyrazinone system [29]. The additional problem here was caused by the capability of the alkene to undergo Diels-Alder reaction with the 2-azadiene system of the pyrazinone. An interesting competition between the Heck reaction and the Diels-Alder reaction has been noticed, while the outcome solely depended on the substrates and the catalyst system. Microwave irradiation of a mixture of pyrazinone (Re = H), ethyl acrylate (Y = COOEt) and Pd(dppf)Cl2 resulted in the formation of a mixture of the starting material together with the cycloaddition product in a 3 1 ratio (Scheme 15). On the contrary, when Pd(OAc)2 was used in combination with the bulky phosphine ligand 2-(di-t-butylphosphino)biphenyl [41-44], the Heck reaction product was obtained as the sole product. When a mixture of the pyrazinone (Re = Ar) with ethyl acrylate or styrene and Pd(dppf)Cl2 was irradiated at 150 °C for 15 min, both catalytic systems favored the Heck reaction product with no trace of Diels-Alder adduct. 

In some pharmacotherapy studies, psychotherapy exposure has been minimized, on the basis of concern that psychotherapy may produce a ceiling effect on improvement in drug or alcohol use, making medication effects difficult to detect. However, a recent meta-analysis revealed that psychosocial interventions, in fact, may enhance pharmacotherapeutic effects (Hopkins et al. 2002). In this review we have also noted instances where psychosocial and medication treatments have had beneficial additive effects. Minimization of psychotherapy in pharmacotherapy trials may be counterproductive, because psychosocial therapies that encourage the patient to remain engaged in treatment may positively affect patients adherence to the medication regimen, a factor that has an effect on alcohol treatment outcomes (Chick et al. 2000 Volpicelli et al. 1997).
