Standard gamble

What was Standard supposed to get from all this Well, someday the Farben gasoline might be cheap enough to rock the foundation of the Standard Oil empire. Then too, perhaps Standard gambled that Farben science would outstrip its own for Standard took as its further share in the bargain a fifty-fifty stake in all future discoveries. All new discoveries of both partners were to be pooled through Jasco. 

The most commonly used direct measurement techniques include visual analog scales, standard gamble, and time tradeoff." ... 

FIGURE 2-2. Standard gamble for a chronic health status. The subject is offered the choice between A and B. A involves the certainty of living in health state /(a suboptimal health state) for a specified period of time. 6 involves an intervention that could lead to full health for the same period of time or immediate death. The probabilities associated with the outcomes of healthy and dead are p and 1 — p, respectively. As p is varied, the indifference point between choices A and B represents the utility of state /. 

The HUI is another generic instrument that describes the health status of a person at a point in time in terms of his or her ability to function on a set of attributes or dimensions of health stams. The HUI Mark lEIII is available as a 15-item self-administered form. The measurements for the development of the health-state preference system were made with visual analog scales (VASs) and the standard gamble technique. The dimensions covered in the most recent version of the HUI (Mark III) are listed in Table 2-2. ... 

In the more complex sort of economic evaluation, cost-utility and cost-benefit analysis, the task of evaluating outcomes on a utility or even monetary scale must be addressed. A device which is used to do this is known as the standard gamble, ably discussed by Spiegelhalter, (1982) and also by Petitti (2000). We wish to evaluate the utility of a certain outcome, C, and to do so we consider that the patient may be offered instead a gamble G whose result will be with probability p the best possible outcome. 

Standard gamble. A means of evaluating a subject s utility of a given outcome by establishing at what value of a probability, p, the subject would be indifferent to trading the given outcome for the best possible outcome with probability p or the worst possible outcome with probability (1 — p). An aid to making decisions favoured by those who prefer hypothetical questions to real ones.

To calculate QALY, we need to estimate the life years of the patient population based on clinical trial data and the health states and their durations during the life years. Health states are usually related to the study endpoints, for example, disease progression or deaths. Multistate analysis can be used to make these estimates. Once the health states are determined, the value or QoL (Q) associated with each state can be established using expert opinion, QoL data collected in the clinical studies, or direct or indirect research. The most frequently used method in practice is direct or indirect research by way of preference survey of health providers and patients. Time trade-off, standard gamble, and rating scale are among the ways to assess the preference of specific health state. As an alternative, indirect research uses questionnaires for health state in several health domains or attributes (e.g., EQ5D) and then to construct a multiattribute utility as a summary measure that reflects preferences both within and across health domains. 

A commercially interesting low calorie fat has been produced from sucrose. Proctor Gamble has patented a mixture of penta- to octafatty acid ester derivatives of sucrose under the brand name Olestra. It was approved by the FDA in January 1996 for use as up to 100% replacement for the oil used in preparing savory snacks and biscuits. Olestra, a viscous, bland-tasting Hquid insoluble in water, has an appearance and color similar to refined edible vegetable oils. It is basically inert from a toxicity point of view as it is not metabolized or absorbed. It absorbs cholesterol (low density Hpoprotein) and removes certain fat-soluble vitamins (A, D, E, and K). Hence, Olestra has to be supplemented with these vitamins. No standard LD q tests have been performed on Olestra however, several chronic and subchronic studies were performed at levels of 15% in the diet, and no evidence of toxicity was found. No threshold limit value (TLV), expressed as a maximum exposure per m of air, has been estabhshed, but it is estimated to be similar to that of an inert hpid material at 5 mg/m. ... 

Three interfaces in the sample of 75 complexes of Lo Conte et al. (1999) have B 1150 A, just below the range 1200-2000 A dehning the standard size. The distinction may be spurious, due to experimental error or to missing contacts. In two of the crystal structures, one of the components is not the complete protein, and, therefore, the interface may be incomplete as in the HIV gp 120-CD4-Fab 27 crystal. These are the complex of a domain of Che A with Che Y [PDB code, laOo (Welch et al., 1998)], implicated in the two-component system of bacterial signal transduction, and the complex of a domain of the HIV capsid protein with cyclophilin [PDB code, lak4 (Gamble etal., 1996)].

Hogarth and Kunreuther [16] found uncertainty of risk knowledge an important factor in consumer decision making. The study was one of the few applied to consumer purchase decisions, but it did not involve online security risks. However, they pointed out that the standard lab cases of gambling used in most prior decision studies did not capture the variety of decision choices faced by people in the real world. Roca, Hogarth, and Maule [24] concurred that future decision research should be extended to a broader range of contexts and response modes, such as willingness to pay for uncertainties and risks. 

ISO standard 770 shows character and data for this oil. Schmidt (2010) reported the Chinese eucalyptus oil coming from Sichuan province and is derived from C. longepaniculatum (Gamble). This must be labeled and it is not correct to mix this up with true eucalyptus varieties. Adulteration is done by 1,8-cineole from various Cinnamomum varieties. The detection is not easy as all these adulterations are natural. 

Procter Gamble and Kaneka have introduced a range of polyhydroxybutyrate-co-hexa-noate (PHBH),imder the trade mark of Nodax (Figure 10.12) [48]. The properties of Nodax are a function of the concentration of the hexanoate, which vary from hard with some flexibility (4%), hard elastic (6%), soft elastic (8%) to soft rubbery (18%), allowing to manufacture materials (injected moulded, films, or fibres), with similar mechanical properties to polyethylene/polypropylene using standard polymer technology.
