Methods. Initially a range of different nonlonlc surfactant-oil mixtures containing 30 w/w surfactant were screened for their ability to self-emulsify in water at 25 and 37°C. Gentle agitation was provided by a glass stirrer as described by Pouton (liL). The efficiency of self-emulslflcatlon was assessed subjectively on a scale of 1 to 5 (bad to excellent) by visual observation. 

The diagnostic assessment, subject to revisions, is fundamental to our model (Table 1-1 ). 

Evaluation Methods. In testing paint materials, paints, and other coating materials, the properties or variations in properties often cannot be described quantitatively but must be assessed subjectively. A uniform system of evaluation has been established in the form of a numerical scale to facilitate the assessment of results and mutual understanding. This system should only be used if a result cannot be obtained as a directly measured value. For standards, see Table 1 ( Test evaluation ). 

Assessing subjective sleepiness is an important issue in our 24/7 society. For instance, workers frequently have to rely on their internal assessment of sleepiness when making decisions about whether they are alert enough to work an extra shift or drive a little further before stopping. Often the subjective feeling of sleepiness may be one of the first cues that a worker has that he or she can no longer function on the job in a safe manner. Obviously this type of self-assessment can have profound safety implications in real-world settings. 

Staff qualifications and availability The investigators study coordinators (also called research nurses, clinical research coordinators (CRCs), or study nurses) play a key role at the investigational site. Their availability and experience are assessed because they screen and enroll subjects, complete subjects case report forms (CRFs), maintain source documents, follow and assess subjects throughout the study, and have more interactions with the CRA and representatives of the pharmaceutical study during study conduction.

Each CER obtained was analysed using a comprehensive set of environmental performance indicators (EPIs). An overall ranking of CERs was made difficult by the lack of a universal standard. In addition, there was frequently little or no quantitative information, making some of the individual EPI assessments subjective. 

There are two effective and equally important ways of assessing subjective preference. The first method involves selecting panelists who match the target consumer population and having them participate in the preference testing of several prototypes of the product. The second method involves providing the product prototype to panelists they then smell it, shake it, use it, etc., and describe what they like or do not like about the product.

The recording of physiological and psychological variables is but one aspect of assessment in applied environments. Basic issues in methodology include the features of field studies as opposed to those of laboratory experiments, the development of adequate assessment strategies, issues in multimetfaod assessment, subject compliance, and method-dependent reactivity. In addition to addressing these issues, several examples of research have been selected in order to delineate a new orientation in ambulatory assessment. 

A nap prior to sleep loss (a prophylactic nap) improves performance compared to no nap. Schweitzer, Muehlback, and Walsh (1992) assessed subjects who received a 2-to 3-hour nap before a night work shift (with concurrent sleep loss), and found that although the morning circadian trough was still evident the nap attenuated performance declines. Bonnet (1991) found that subjects who napped before 52-houis of continuous wakefulness performed better and were more alert for up to 24 hours of sleep loss compared to those who did not nap. 

This is analogous to the problem of structural safety. If a structure is a one-off design, there is no repeatable experiment which can be set up to test the statement the probability that the structure will fail in the collapse limit state of plastic mechanism X is low . It can only be done through tests and assessments made on structures and components of structures which are not precisely the same as the structure in question but the degree of similarity has to be assessed subjectively. 

In an effort to identify the predominant factors involved in structural failures, I considered and assessed in detail the case studies presented in the previous two chapters plus several other reports of failure, a total of 23 incidents [96]. The check list of statements presented in Section 7.2 was used in the assessment with the exception of statement 4(f). The truth or dependability of each statement and its importance with respect to each accident was assessed subjectively with the benefit of hindsight. The assessments were made, in fact, on the basis of five categories for each as follows ... 

PST prepares both general and periodic threat assessments subjected to the risk of terrorist attack. The risk assessments of PST are in most cases not giving any more information than their exact assessment of the threat which has been either low or moderate. When PST decided to increase the risk level in Norway from low to moderate after Al-Qaeda announced the second terrorism threat, there was hardly any information about what the assessment was based on and why they decided to increase the level to moderate, which they did not after the first. However, PST contributes with qualitative statements that give the impression of an imminent terrorist threat. Jam Hohne, the current Director of PST, claims that it is just a matter of time before terrorists strikes Scandinavia (Jam Holme, Director of PST, in Aftenposten 15.12.2005). 

Risk mapping is a subjective process where the risks are broadly classified based on risk occurrence and risk impact. Risk occurrence measures the likelihood of that risk event happening and is subjectively assessed as high or low. Risk impact is used as an all-embracing term that covers financial loss, market share, stock prices, etc. Risk impact is also assessed subjectively as high or low. Based on the assessment of risk occurrence and risk impact, a 2 x 2 matrix of risk map can be constructed as shown in Figure 7.1 (Elkins et al., 2008a). 

Recent developments take the risk assessment subject to a higher level within the practice of safety. By formalizing the hazard analysis and risk assessment process, a better appreciation of the significance of individual risks is achieved. As risks levels are categorized and prioritized, more intelligent decisions can be made with respect to their elimination or reduction. For the hazard analysis and risk assessment process, it is necessary to arrive at definitions of hazards, hazards analyses, risks, and risk assessments.
