Sample Case Interviews

An example of the type of question you might hear at an estimation interview is, "How many pieces of luggage are unloaded at LaGuardia Airport each day " To see how you might go about answering this question, and for more sample case interview questions, see Appendix G. 

This research process continued for a period of 2 years due to the longitudinal nature of the case. The samples evolved over the course of the investigation, some samples were interviewed several times because of their relevance to the study, and others were interviewed only once, but nevertheless provided key information and relevant links to other samples. 

Soil properties A Soil texture (sand, silt, clay), organic matter/carbon content, and pH Stones, roots, and hardpans must be largely absent to allow representative sampling of soil profile Soil properties should appear uniform over test site Soil texture data should be available at time of site selection. Soil properties must match study purpose. This can be realistic use conditions, realistic worst-case or worst-case in terms of agrochemical mobility and persistence Must ensure that the majority of samples can be taken from the deepest sampling horizon. Information about sub-soils can be obtained from soil maps, test coring and on-site interviews... 

Even in cases where detailed information is available, there is often considerable divergence in definitions used - registry data (people in contact with the treatment system or the judicial system) versus survey data (usually extrapolation of results obtained through interviews of a selected sample) general population versus specific surveys of groups in terms of age (e.g. school surveys), special settings (such as hospitals or prisons), life-time, annual, or monthly prevalence, etc. 

Before starting the analysis every effort should be made to obtain details of the circumstances leading to the complaint or suspicion of doping or poisoning. Every case must be accompanied by an enquiry form similar to that shown on p. 39, and this should be supported, when possible, by an interview with the police officer. Was the suspect material tasted If not, what aroused suspicion Is die victim ill What are the symptoms Without clues to guide the selection of tests and screening systems, the sample is a general unknown . 

Blood donor records were used to select 124 male volunteers in Sardinia comprising 60 with the normal G6PD phenotype and 64 with the G6PD-deficient phenotype. Individuals with abnormal blood chemistry parameters and possible cases of thalassaemia were excluded from the study. Individuals were interviewed, and personal details, place of residence and type of drinking-water normally consumed were recorded. Blood samples were taken, and the following blood parameters were measured red blood cells, mean corpuscular haemoglobin, mean corpuscular volume, white blood cells, indirect bilirubinaemia and serum ferritin. The... 

Analyses of interviews were conducted based on the principles of grounded methodology (Strauss and Corbin, 1998) and case study research (Yin, 1989 Stake, 1995). The paper reports from an explorative smdy with a mainly qualitative approach. We have first and foremost relied on in-depth studies, with relatively few cases and informants, rather than quantitative analyses of representative samples. It should also be noticed that we have substantive work experience with the two industries in question, to the level that we have been interacting with several of the interviewees on previous occasion. A conventional understanding is that the researcher should be neutral and distant from... 

Sequential mixed methods procedures are those in which the researcher seeks to elaborate on or expand on the findings of one method with another method. This may involve beginrting with a qualitative interview for exploratory purposes and following up with a quantitative, survey method with a large sample so that the researcher can generalize results to a population. Alternatively, the study rrray begin with a quantitative method in which a theory or concept is tested, followed by a qualitative method involving detailed exploration with a few cases or individuals. 

Of the five interviews summarized in this chapter, all were with individuals who had at least 20 years of experience in the aviation industry, and three of them had close to 30 years of experience. Although relatively few interviews were conducted, the interview candidates were chosen for their extensive experience, and in some cases their role as opinion leaders within the industry. Therefore, they can appropriately be viewed as experts, rather than as a representative sample from within the industry. 

The cases who were interviewed formed a selected sample. They were selected from those who gave a positive response on the questionnaire, but selection was weighted towards the upper end of the frequency of abuse distribution. Table 17 compares the frequency of solvent abuse among the interview-confirmed cases... 

Tbe selection of cases for detailed assessment was intentionally biased toward the inclusion of those who had abused solvents mtxe fi uently, although, as far as could be ascertained, the cases identified by questionnaire and those confirmed at interview appeared to be closely comparable on other sniffing variables. Nevertheless, the possibility that the findings fit>m the interview-confirmed cases reflect a somewhat heavier pattern of abuse than that which obtained in the gen population needs to be kept in mind. Finally, information on the persistence of solvent abuse over the nine months following the initial interview comes from the sample of cases who were traced and examined at follow-up.
