The text introduces basic concepts of cohort analysis – age, period and birth cohorts. The author shows the role of birth cohorts in explanation of social processes and deals with a cohort replacement as a matter of social change. From the methodology point of view the author presents the standard cohort table, introduces an identification problem and shows two ways how to solve it using the data on birth rates in the Czech Republic between 1948 and 2007. The first solution is presented for population data, the second one is presented for microdata in the form of a series of repeated cross-section sample surveys. The results of both analyses show, that identification of age, period and cohort effects is important for interpretation trends in birth rates in the Czech Republic between 1948 and 2007., Tomáš Katrňák., and Obsahuje bibliografii a bibliografické odkazy

Cílem výzkumu bylo zmapovat situaci v užívání legálních drog, tabáku a alkoholu, u dětí na základních školách Jihočeského kraje. Výzkum se zaměřuje jak na pravidelné uživatele těchto legálních drog, tak na reprezentativní vzorek mladých lidí, kteří jsou potenciálně (a pochopitelně i reálně) ohrožených legálními drogami., Markéta Kastnerová., and Seznam literatury
An increasing number of surveys are employed in the field of public administration. This begs the question, what is the quality of this form of research? In this article two different surveys are presented and compared. First, a client satisfaction survey implemented at twelve municipal offices is examined. Second, there is an exploration of an international comparative research project that studies municipal representatives (MAELG). An examination of the research methodologies employed in both of these two surveys reveals the problems inherent to this type of inquiry. Strategies for overcoming these obstacles in future research are described. This study argues that examination of methodological issues can lead to important substantive insights; in this case it is the link between public administration and democracy., Dan Ryšavý., and Obsahuje bibliografii a bibliografické odkazy
