- Articles and reports: 88-003-X200800210742Geography: CanadaDescription:
In its recently released science and technology (S&T) strategy, Mobilizing Science and Technology to Canada's Advantage (Government of Canada 2007), the federal government stated its commitment to improving its ability to measure and report on the impact of federal S&T expenditures. In response to this challenge, the Policy Research Initiative (PRI) collaborated with departments and agencies that conduct and fund S&T to explore these issues. This article provides a summary from one of the PRI reports, The Transmission of Technology and Knowledge to Innovative Manufacturing Firms by Publicly Funded Research Organizations.
Release date: 2008-11-21 - 2. Respondent incentives in a multi-mode panel survey: Cumulative effects on nonresponse and bias ArchivedArticles and reports: 12-001-X200800110607Description:
Respondent incentives are increasingly used as a measure of combating falling response rates and resulting risks of nonresponse bias. Nonresponse in panel surveys is particularly problematic, since even low wave-on-wave nonresponse rates can lead to substantial cumulative losses; if nonresponse is differential, this may lead to increasing bias across waves. Although the effects of incentives have been studied extensively in cross-sectional contexts, little is known about cumulative effects across waves of a panel. We provide new evidence about the effects of continued incentive payments on attrition, bias and item nonresponse, using data from a large scale, multi-wave, mixed mode incentive experiment on a UK government panel survey of young people. In this study, incentives significantly reduced attrition, far outweighing negative effects on item response rates in terms of the amount of information collected by the survey per issued case. Incentives had proportionate effects on retention rates across a range of respondent characteristics and as a result did not reduce attrition bias in terms of those characteristics. The effects of incentives on retention rates were larger for unconditional than conditional incentives and larger in postal than telephone mode. Across waves, the effects on attrition decreased somewhat, although the effects on item nonresponse and the lack of effect on bias remained constant. The effects of incentives at later waves appeared to be independent of incentive treatments and mode of data collection at earlier waves.
Release date: 2008-06-26 - 3. The Business of Nurturing Businesses ArchivedArticles and reports: 88F0006X2008002Description:
This paper is based on the findings of the Survey of Technology and Electronic Commerce (SECT), which in 2005 included a module on business incubation service providers and users. The results of the Survey of Business Incubators (SBI) were discussed in Joseph, Bordt and Hamdani (2006). The main difference between the two surveys is that the SBI focused on business incubators (BIs), firms that provided business incubation as their main line of activity the criterion used to define industry boundaries in statistical systems whereas the SECT covered all firms that provided business incubation services to new companies, whether it was their main activity or a small part of the business.
Release date: 2008-03-27 - 4. An algorithm to differentiate diabetic respondents in the Canadian Community Health Survey ArchivedArticles and reports: 82-003-X200800110533Geography: CanadaDescription:
This article describes an algorithm to classify respondents to cycle 1.1 (2000/2001) of the Canadian Community Health Survey according to whether they have type 1, type 2 or gestational diabetes.
Release date: 2008-03-19 - 5. The U.S. National Health and Nutrition Examination Survey: what forty years of experience has taught us ArchivedArticles and reports: 11-522-X200600110413Description:
The National Health and Nutrition Examination Survey (NHANES) has been conducted by the National Center for Health Statistics for over forty years. The survey collects information on the health and nutritional status of the United States population using in-person interviews and standardized physical examinations conducted in mobile examination centers. During the course of these forty years, numerous lessons have been learned about the conduct of a survey using direct physical measures. Examples of these "lessons learned" are described and provide a guide for other organizations and countries as they plan similar surveys.
Release date: 2008-03-17 - Articles and reports: 11-522-X200600110449Description:
Traditionally administrative hospital discharge databases have been mainly used for administrative purposes. Recently, health services researchers and population health researchers have been using the databases for a wide variety of studies; in particular health care outcomes. Tools, such as comorbidity indexes, have been developed to facilitate this analysis. Every time the coding system for diagnoses and procedures is revised or a new one is developed, these comorbidity indexes need to be updated. These updates are important in maintaining consistency when trends are examined over time.
Release date: 2008-03-17 - Articles and reports: 11-522-X200600110453Description:
National Food and Nutrition Surveys provide critical information to support the understanding the complex relationship between health and diet in the population. Many of these surveys use 24 hour recall methodology which collects at a detailed level all food and beverages consumed over a day. Often it is the longer term intake of foods and nutrients that is of interest and a number of techniques are available that allow estimation of population usual intakes. These techniques require that at least one repeat 24 hour recall be collected from at least a subset of the population in order to estimate the intra individual variability of intakes. Deciding on the number of individuals required to provide a repeat is an important step in the survey design that must recognize that too few repeat individuals compromises the ability to estimate usual intakes, but large numbers of repeats are costly and pose added burden to the respondents. This paper looks at the statistical issues related to the number of repeat individuals, assessing the impact of the number of repeaters on the stability and uncertainty in the estimate of intra individual variability and provides guidance on required number of repeat responders .
Release date: 2008-03-17 - Articles and reports: 89-552-M2008019Geography: CanadaDescription:
Using data from the International Survey of Reading Skills, this report identifies the reading profiles of different groups of adult Canadians with low literacy skills, examines in depth their reading abilities, and describes their varied literacy learning needs. The new insights offered will inform the development of more targeted literacy policies and will be useful to both researchers and practitioners in designing and delivering appropriate and effective reading instruction programs for Canadian adults.
