This article outlines how different types of survey response reliability are estimated and used within the social sciences. Implementing the Classical Test Theory’s concept of reliability in a panel survey exploring opinions and attitude crystallization in a Czech town. Estimates of the test-retest reliability of respondents’ political orientation are estimated using four different approaches. Political orientation is measured using a standard 10 point left-right scale. It also estimates the ‘true score’ of a respondents’ political orientation; and shows the implications of measurement precision for the estimation of this individual level trait. Inter-item reliability is calculated using a 4 item scale composed of dichotomous indicators. This analysis reveals that the estimated reliability of the political orientation scale depends on the number of items used to construct the scale. More concretely the 10 point left-right political orientation scale exhibits a satisfactory level of test-retest reliability demonstrating its validity in making inferences about the target population. The analyses presented in this study were estimated using the R statistical programming language and LISREL - a specialized software package for estimating structural equation models., Jan Schubert., and Obsahuje bibliografii a bibliografické odkazy
The article represents a probe to the godparenting ties in the parish Hlinsko (former region of Chrudim) at the middle of the seventeenth century from the social-religious point of view. On the basis of the analysis of the register of baptisms from the years 1645 to 1650 and the subsequent combination with the Register of subjects according to their religion from the year 1651 it was possible to ascertain the social position of godparents, their religious affiliation (as contrasted to the denomination of parents of the child), the frequency of participation of godparents in baptisms and other facts that contributed to the functioning of the confessionally divided Czech village society of the Early Modern Era., Ladislav Nekvapil., and Obsahuje bibliografii
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
