Extensive testing was also carried out to assess future hazards for human habitation and residential use of the area. This testing was carried out in an extensive program funded by EPA In 1980-81 after remedial drainage construction work at the Canal was complete (O. All of the survey design and technical laboratory problems described above were encountered in this program. Despite extensive efforts to meet requirements for sample size and distribution, to provide for adequate control sampling away from the Canal area, and...

However, since the data used in this study are subject to the limitations and uncertainties cited above, the results of this analysis represent only a very rough approximation of the national frequency distribution of indoor radon levels. EPA s national survey will seek to more accurately characterize this distribution through use of a larger sample size, a statistically based survey design, and consistent, quality assured sample collection and measurement procedures.

Accuracy is the distance of a measured or estimated value to its true value. Inaccuracies (systematic deviations or bias) may arise from inadequate survey design and processing of the samples. Expert judgment is needed to assess the accuracy however, that implies that the origin and the extraction of the data is described (sampling design and conditions). 

On that day, the official reported the submission of the samples to his former superior. When questioned about why the hair from the captive and stuffed lynx had been submitted, the then-retired official and the others who had made the submissions said they wanted to test the laboratory to be certain it could detect lynx hair. They did so with no authorization, and because such testing of the laboratory was not included in the survey design, they had no way to inform the laboratory of the unauthorized submissions. The laboratory, not knowing the origin of the samples, counted the hair from the captive and stuffed animals as indicating that lynx were present at scratching posts in the forests in Washington State. 

Data covering the design, construction and operation practice of the Trans Caucasian main gas pipeline have been collected and accumulated since the beginning of the 1980-ies. The pipeline design was drafted by the Kiev Survey-Design Institute without properly considering the complex geotechnical conditions, and the possible adverse consequences. Rather...

Future studies of biogenic emissions should be designed to include sufficient data for uncertainty analyses of flux estimates. It is also important to conduct intercomparisons ot different sampling and measurement methods, as well as the methods used for estimating emissions, i.e. the dynamic chamber vs the micrometerological methods. Additional data are required to confirm emission estimates for those environments which have been characterized, and to extend the emission estimates to environments which have not been studied. Studies in ecosystems such as tropical rain forests should include surveys designed to identify potential terrestrial "hot spots of volatile sulfur emissions. 

A new survey designed to cover six city areas in the U.S. is now under way 187>. This will determine if the previous conclusions are still valid, and whether there have been any significant changes in lead levels in five years in either the atmosphere or people as a result of the present types of lead use. Lead levels in the marine atmosphere over the central Pacific Ocean have recently been studied for comparison with the land atmosphere 92>. 

Clearly, the data for food consumption is a very important component of the dietary exposure model. There are some differences in the approaches taken in the US and in the EU, although food consumption data are not collected or treated the same way across the EU. In addition to differences in survey design and collection methods, the organization of the data can also have an impact upon the dietary risk assessment. 

This is the power of the JTBD concept and technique it helps the innovator understand that customers don t buy products and services they hire various solutions at various times to get a wide array of jobs done. You may need light survey design and sampling help from a statistician to apply this technique, but for the most part it requires no expert assistance. 

The observed seismic data are usually bandlimited, because the frequency range is limited by the natural time constant of the source process, by receiver and survey design, by seismic preprocessing required for noise removal, etc. (see Aki and Richards, 2002, and Bleistein et al., 2001 for further discussions). The bandlimiting is an important characteristic of observed seismic data which should be taken into account, especially if we use the high frequency asymptotics for data inversion. 

Surveys designed to test the possible cormection between a history of eating foods rich (or poor) in folate, rich (or poor) in vitamin Be, and the eventual diagnosis of cardiovascular disease. 

These and other problems are real and must be addressed if national survey data on drug use are to have the utility that they are intended to have. Fortunately, over the years the challenge to collect accurate survey information has been an active research area, and methods of representative sampling and data collection to assure confidentiality or anonymity of responses have led to better survey design and procedures. These advances have resulted in data that meet high standards of reliability and accuracy. This is not to say that national survey data provide a literal picture of drug use in a population but that the picture is getting clearer and more detailed as survey research methods continue to improve. 

Survey Design. To ensure that the respondents addressed the areas of sustainability - economic, environmental, and social - the survey presented three commonly used definitions for sustainability3 and respondents were asked to consider their responses in terms of those definitions. This was critical given the broad array of definitions and understanding related to the concept of sustainability.

Choice of the sample from the samphng frame is well covered in sociology texts. Within human factors it typically arises in the context of survey design (Sinclair 1990). To mate statistical inferences from the sample to the population (specifically to the sampling frame), our sampling procedure must allow the laws of probability to be applied. The most often-used sampling methods are ...
