The following techniques can be used to collect data about human performance in CPI tasks and provide input to task analysis methods described in Section 4.3. These data can include process information critical for the task, control strategies used by the workers, diagnostic plans etc. A distinction can be made among data collection methods that provide qualitative data (such as interviews, observations, and sources of documentation) and methods that can be used to measure aspects of performance (such as activity analysis, simulations, and information withholding). The latter methods can provide more precise data which can be quantified. 

The intention of this chapter has been to provide an overview of analytical methods for predicting and reducing human error in CPI tasks. The data collection methods and ergonomics checklists are useful in generating operational data about the characteristics of the task, the skills and experience required, and the interaction between the worker and the task. Task analysis methods organize these data into a coherent description or representation of the objectives and work methods required to carry out the task. This task description is subsequently utilized in human error analysis methods to examine the possible errors that can occur during a task. 

Specify Data Collection Methods and Responsibilities Several types of data collection have been specified in earlier sections. It is important that the responsibilities for operating the various aspects of the system are imambiguously defined. 

Until recently, pure paper-based data collection systems have predominated in clinical trials. However, they are still being used by many contract research organizations (CROs) either because of financial constraints that prevent them from investing in newer technology or because they deal with small clinical trials that do not justify that investment. Other CROs consider the paper-based data collection method to be the safest and most reliable approach to data collection.

The strengths of observational cohort studies are the depth and quality of data that may be collected. Even though these studies are imstruc-tured in the sense that there are no limiting criteria in respect of patient, drug or dosage, they are defined in size and duration and data collection methods, whether on paper forms or on computer screens, and they can draw the attention of the participating doctor to particular pieces of information that are highly desirable. Should data be deficient or inconsistent then it is a relatively simple matter to go back to the doctor for clarification. 

The term pharmacovigilance has now been adopted by all Member States for the activities involved in the study and evaluation of drug safety. Although pharmacovigilance covers a broad range of data collection methods, it is the spontaneous reporting systems sponsored by all European governments to which the term usually refers. 

Experimental methods have not been covered, as they are still developing rapidly. New developments, in particular the advent of third-generation synchrotron sources combined with parallel data collection methods and new interpretative software packages, are bound to further enhance the scope of the field. It is hoped that this text will serve to stimulate its continuing development. 

Time-resolved x-ray crystallography (TC) is a more recent advanced application of x-ray crystallography. It uses an intense synchrotron x-ray source and data collection methods to reduce crystallographic exposure times. This allows multiple exposures to be taken over time at near-physiological, crystalline conditions to determine the structures of intermediates. A typical problem with this method is that the existence of the intermediates is brief, resulting in difficulty in interpreting the resulting electron density maps. 

In Step 3, the planning team will identify the types of information required for answering the principal question defined in Step 2 and determine the availability of appropriate data collection methods. The team will conduct the following activities ...

The corresponding ASAXS profiles, Imom(q), are shown in Fig. 19.6D. Note that the difference signal is small. This signal arises from approximately 40 Rb+ ions per 25 bp DNA and typically is one order of magnitude smaller than the on- or off-energy SAXS profiles. However, these ASAXS data collection methods produce results that are robust and reproducible between runs. 

Descriptions of model input variables, e.g. data collection methods, analytical methods, data transformation procedures, etc., should be stated. Furthermore, appropriate statistical measures should be included for both input variables and model results (output) to facilitate qualitative and quantitative evaluations of uncertainty and appropriate interpretations. 

Data collection methods at individual facilities should be assessed to ensure that the proper techniques are used. Audit the procedures. 

The majority of experimental powder diffraction patterns in the following five examples were collected using a step scan data collection method on a Scintag XDS2000 system equipped with a Ge(Li) solid-state detector cooled with liquid nitrogen. 

Post-registration clinical studies must be carried out using a written protocol that will provide answers to specific research questions. The protocol must be designed to ensure scientifically meaningful results, and should contain details about study objective, study population, methodology, information to be obtained and data collection method. 

Because a number of conceptualizations of patient satisfaction can be used, the measurement of patient satisfaction must fit the context of the overall research process. A research process proposed by Churchill involves six stages 1) formulate the problem 2) determine the research design 3) design data collection method and forms 4) select a sample and collect the data 5) analyze and interpret the data and 6) prepare the research report. Each stage is linked, and decisions made at one stage will affect decisions made at other stages.
