Data were analysed by χ2, ANOVA and correspondence analysis.FindingsThree teaching‐and‐learning methods are most common in both environments: practical exercises, case studies and lectures.

Formal Contractual Agreements: A Transaction Cost Study of Tanzania Firms
2011
This is exploratory study that aims at examining formal contractual agreements for firms in Tanzania using Transaction cost theoretical approach. Transaction cost studies have rarely being done on firms in Africa and Tanzania in particular. Sampling frame used is from Tanzania revenue authority records for registered business 2008-2010. The study is centered on business - to business buyer -seller relations. Primary data were collected from buying side of this business relationship. Random sample of n =150 buyers were contacted through telephone calls and questionnaire were delivered personally. The response rate was about 65%. The findings suggest Transaction cost theoretical framework to …
Recommendations for design and analysis of health examination surveys under selective non-participation
2019
Background The decreasing participation rates and selective non-participation peril the representativeness of health examination surveys (HESs). Methods Finnish HESs conducted in 1972–2012 are used to demonstrate that survey participation rates can be enhanced with well-planned recruitment procedures and auxiliary information about survey non-participants can be used to reduce selection bias. Results Experiments incorporated to pilot surveys and experience from previously conducted surveys lead to practical improvements. For example, SMS reminders were taken as a routine procedure to the Finnish HESs after testing their effect on a pilot study and finding them as a cost-effective way to inc…
Non-response bias as a likely cause of the association between young maternal age at the time of delivery and the risk of cancer in the offspring.
2003
Some epidemiological studies have shown an association between young maternal age at the time of delivery and risk of cancer in the offspring. In a recent German case-control study, there was a twofold increase in the leukaemia risk for children whose mothers were aged < 20 years at the time of delivery. As the prevalence of younger mothers among control families was particularly low, data on maternal age distributions for the general population of Germany were obtained in order to examine the representativeness of the control sample. Despite the excellent sampling frame based on data from complete and up-to-date population registries and a satisfactory response rate among controls ( approx…
SAMPLING DESIGN IN SHARE WAVE 7
2019
This chapter documents the sampling design adopted in SHARE. Starting with a definition of the SHARE target population, we describe the protocol that is followed to harmonise and document the sampling procedure and present the sampling frames used by the countries that recruited a baseline or refreshment sample in Wave 7. We then discuss some important aspects of the SHARE sampling design, such as stratification, clustering, variation in selection probabilities and sample composition. Finally, we provide additional information about the sampling variables included in the released SHARE dataset.
