In Italy, food-borne outbreaks of opisthorchiasis have occurred since 2003, all of them originating from some lakes in Central Italy where the only European liver fluke, Opisthorchis felineus (Rivolta, 1884) is endemic. The aim of the present study is to investigate the factors that may facilitate the life cycle of O. felineus in the area of Bolsena Lake, the knowledge of the local population about opisthorchiasis, and preventative healthcare measures. We performed a descriptive observational study through the submission of questionnaires to three target populations: fishermen who fish exclusively in Bolsena Lake, restaurateurs whose businesses are close to the lake and general population living in the province of Viterbo. Results showed hazardous behaviours and eating habits in the three target populations, as well as a poor knowledge of opisthorchiasis and preventative healthcare measures., Paola Scaramozzino, Roberto Condoleo, Enrica Martini, Teresa Bossù, Silvia Aquilani, Valentina Spallucci, Elisabetta Aquilini, Selene Marozzi., and Obsahuje bibliografii
In the year 1909 was established in Prague Minority Museum as a mutually-supportive institution. Its goal was to pay attention to demographic problems, expecially the distribution of Czech minorities in nationally mexed (Czech-German) regions in the borderlands, as well as collection of documents on national, cultural and social situation. One of the concrete activities of the museum was to pursue guestionnaire surveys, on the basis of which was expected to enquire the situation of Czech minorities on Czech-German territories. The article shows how the questionnaires were processed and distributed. Given the fact that the archival collection "Minority Museum 1909-1920" in the National Archives in Prague contains only a torso of filled questionnaires, it can be speculated that in the period before the World War I it was not possible to realize this project., Andrej Sulitka., and Obsahuje bibliografii
The aim of this article is to provide an overview of the problems associated with the fielding of questions of a socially sensitive nature typically dealing with crime, health, and sexual activity in nationally representative sample surveys. This article presents an overview of previous research on this topic and associated themes such as the definition of sensitive survey questions, the emergence and impact of social desirability effects and application of the Cognitive Aspects of Survey Methodology (CASM) to mechanisms of question response on sensitive topics. Thereafter, this article maps out specific sources of error that are likely to occur when fielding sensitive survey questions; and highlights methods that may used to minimise measurement error, thereby enhancing data validity. The article concludes with an appraisal of some of the most influential criterion-validity used in this sub-field of survey research., Johana Chylíková., and Obsahuje bibliografii a bibliografické odkazy
