Elicitation process

The capability to modify the sequence of questions interactively means that the information elicitation process can home-in on particularly useful areas for establishing causes.

One criticism against the use of informative priors is their subjective nature, which may be perceived to introduce bias into the upcoming analysis. The choice of priors and assigning an appropriate level of informativeness is therefore of considerable importance. For population PK/PD studies, there may well be explicit, quantitative data that describes the parameter values in populations that are similar to the population in the current study. In this case it is possible to pool the available information in a meta-analytic technique to provide an appropriate level of prior information. Some care must be taken to assess for heterogeneity between studies and for applicability of studies to the current population under consideration. A brief summary of an approach is shown below. It would be impossible to include an exhaustive treatment of elicitation processes within the confines of this chapter. 

In contrast to antibodies that nndergo mntation and stmctnral pertnrbation during the eliciting process, the chemical synthesis of aptamers nsnally leads to highly reproducible structures of the binding ligands. 

Identilying stakeholders— individuals or organizations who stand to gain or lose from the success or failure of a system— is also critical. Stakeholders include customers or clients (who pay for the system), developers (who design, construct, and maintain the system), and users (who interact with the system to get their work done). For interactive systems, users play a central role in the elicitation process, as usability can only be defined in terms of the target user population. Users themselves are not homogeneous, and part of the elicitation process is to identify the needs of different user classes, such as novice users, expert users, occasional users, disabled users, and so on. 

Model-driven techniques provide a specific model of the type of information to be gathered, and use this model to drive the elicitation process. These include goal-based and scenario-based methods. 

Of course, in some circumstances a full-blown method may be neither required nor necessary. Instead, the requirements engineer needs simply to select the appropriate technique or techniques most suitable for the elicitation process in hand. In such situations, technique-selection guidance is more appropriate than a rigid method. 

Modeling goals is particularly useful in RE. High-level business goals can be refined repeatedly as part of the elicitation process, leading to requirements that can then be operationalized. 

The modelling techniques used when designing a BN model also affects the probability elicitation process. Thus the analyst can use BN specific measures in addition to techniques for probability elicitation to ease the assignment of conditional probabilities. 

Where k + ki + hi = 1. These are scale constants which are estimated by procedures based on comparisons of an elicitation process by lottery (KEENEY RAIFFA, 1976). 

Designing elicitation process The references in Section 2.4 all include a design activity related to structuring the questions we want to ask the experts, even though they use some different expressions. Cooke (1991) defines some recognized principles to follow when designing an expert elicitation process ... 

Meyer Booker (1991) warn of using too many experts together in an elicitation process, due to potential conflicts that may arise from group dynamics, such as follow the leader effect. 

Meyer Booker (1991) emphasize training not only for the experts, but also for the team managing the process. Organizing a large elicitation process... 

The elicitation activity in a formal elicitation process is where knowledge actual becomes numbers. The activity may include one or more experts, face-to-face interviews, group sessions, or other types of communication. Garthwaite et al (2005) present an iterative process for this activity ... 

Table 1. Roles in a formal expert eliciting process. 

O Hagan et al. (2006) point out that the process can be performed by only two persons if necessary, one expert and one analyst. Often there is also a decision maker included however, as O Hagan (2006) says, the expert and decision maker may be one and the same, and if the analyst also is capable within statistics, the process can be performed by only two persons. However, both O Hagan et al. (2006) and Meyer Bookers (1991) include more roles to the process. These are often necessary in larger formal expert eliciting processes. Table 1 gives a summary of actual roles described in the processes of the referred literature. 

The design of the ehcitation process in less resource intensive risk assessments should, as any other elicitation processes, ensure compliance with the main principles mentioned in section 2.4.2 (reproducibility, accountability, empirical control, neutrality, fairness). However, in smaller and less resource... 

The elicitation activity, the data collection, is not different in smaller and less resource intensive risk analysis than in other elicitation processes, maybe except for a less comprehensive scope, with fewer runs. 

Table 2 summarizes the suggested activities for a knowledge-to-number process, in smaller risk assessments, highlighting differences compared to formal expert eliciting processes. It shows the... 

Design Simplified elicitation process. - Design - Data collection - Data analysis Simplified plan for data analysis. 

The purpose of this paper has been to point out how we can improve smaller risk assessments by improving the use of expert knowledge. Today s utilization of expert knowledge in smaller risk assessments often do not follow proposed formal expert eliciting process activities. Despite limited resources in smaller risk assessments, we believe a simple, yet more structured process will increase the quality and contribute to more valuable decision support, increasing the decision maker s confidence in the result. 

User-centered design is not just about building nice-looking and usable user interfaces, and software development is not just about implementing functionality that supports user tasks. Belonging to different traditions and times, the disciplines of software engineering (SE) and human computer interaction (HCI) have evolved separately and developed their own methods to meet the needs of software application customers and users. Over the last twenty years, especially, several practices have been developed in both communities. This illustrates the human-centered perspective s influence on the software development lifecycle. Stakeholder involvement in the requirements elicitation process and evolutionary process models [39], which enable iterative construction of the application software to best meet the user requirements, and the widespread use of prototyping by the HCI community are examples of the approximation of both disciplines [31]. 

In order to determine at what point in the elicitation process Ca was active, potato tuber discs were treated with AA and then supplemented at later times with Ca Rishitin accximulation was enhanced only if Ca was added within 24 h of the application of AA. Strontium had a similar effect on AA-elicited rishitin accximulation. Likewise, Ca and Sr had to be applied early after application of poly-L-lysine (within 6 h) to be effective in enhancing rishitin and lubimin accumulation.
