Description:
The paper presents to Czech social scientists an introductory review of the concept of equivalence and the method of blockmodeling in social network analysis (SNA). After introducing the central concepts of SNA such as node and tie, along with their basic metrics such as centrality and cohesion, I present the concepts of role and position. These are treated by SNA as clusters of nodes with similar ties, something I juxtapose to algorithms to identify cohesive subgroups of nodes. Subsequently, I define and compare the two most frequently applied types of equivalence - structural, which is strict but broadly applicable, and regular, which is more liberal but has limited uses. Structural equivalence builds on a strict definition of similarity of ties, treating as equivalent only such nodes that have the same ties to the same other nodes. Regular equivalence works with looser criteria and better corresponds with both the theoretical and the intuitive notions of role; this, however, is outweighed by the absence of a unique regular-equivalent solution within a network and by the difficulty to process networks with undirected ties. Regular-equivalent nodes are such that have ties to other mutually equivalent nodes. I present examples to demonstrate the differences between both definitions. In the following section, I discuss measurement of similarity between the different nodes’ profiles of ties (e.g., correlation and Euclidean distance) and possible uses of the standard statistical methods of cluster analysis and multidimensional scaling to detect equivalent classes of nodes within networks. After pointing to the weaknesses of these techniques in network data analysis, I present blockmodeling as a method designed specifically to identify roles and positions within networks. Ischematize the blockmodeling procedure and present its basic terms before comparing classic inductive blockmodeling, which is primarily fit for the purposes of exploration and network reduction, with deductive generalized blockmodeling, which is applicable in testing hypotheses about basic structural characteristics of a network. I bring attention to the strengths and weaknesses of both approaches. Relatedly, I present an application of blockmodeling especially for the purposes of simplified network representation, comparing structural patterns across networks, and testing structural theories. In the following section, I demonstrate specific blockmodeling algorithms based on both structural equivalence (CONCOR and Tabu Search optimization) and regular equivalence (REGE and Tabu Search optimization). Then I verify the adequacy of their resulting assignment of positions to nodes using eta coefficient, Q modularity and correlation of the ideal blocked and the empirical adjacency matrices. In the concluding section, I demonstrate the entire blockmodeling procedure on an empirical case of a small network with undirected ties using the UCINET software tool, including interpretation of results. Finally, I reflect the contemporary position of blockmodeling among leading research approaches in SNA, referring to other empirically oriented studies that demonstrate the broad applicability and utility of position analysis., Tomáš Diviák., and Obsahuje použitou literaturu a poznámky

Description:
The goal of the text is to analyze concordance between one’sreligion and a close relative’s estimation thereof. To establish the accuracy of parents’ estimates of their children’sreligion and vice versa, we ask the following question: what is the concordance of post-socialization beliefs about (un)successful transmission of religiosity between direct actors (parent/child)? We argue that the reliability of that estimate indicates the effectiveness of religious socialization. Socialization is not treated as a nonproblematic one-way process, but rather as a result of repeated mutual parent-child interactions and a host of other intervening factors (secondary socialization etc.) In this context, the level of estimate reliability is treated as an indicator of religious socialization and of the continuity of religious memory within family, which is viewed as a collective phenomenon. In other words, by imprinting values into one’s memory and worldview, the process of religious socialization shapes the ways one views the world and him/herself as well as the focus of his/her attention, or what is stored in his/her memory. Our project is conceptualized at an intersection of the theories of socialization and religious memory. Among the latter, we primarily rely on Jan Assmann’s conceptualization of memory. While many contemporary authors deal with issues of religious socialization, and some even with its links to memory, no investigations thus far have attempted to verify intergenerational transmission in terms of the reliability of mutual estimation of (non)religiousness between generations. The analyses are based on data from the KODINA 2015 survey which specifically complemented its main sample with a selection of respondents’ close relatives. This allows us to analyze a sample of parent-child dyads. Simple frequency tables revealed some effects of the accounting person’s generation on estimate concordance. Specifically, parents were much more likely to misjudge their children’s religiosity - to consider them Roman Catholic although the children themselves identified as nonbelievers. Logistic regression was used for more detailed analysis, which revealed that the discordance between parents’ and children’s estimates is not statistically significant and only a partial effect could be demonstrated in interaction with the estimating person’sreligiosity. In sum, we present three main findings: (1) close relatives estimate each other’sreligiosity relatively accurately. That indicates, as we argue, the importance of the socialization process. (2) Estimate accuracy depends on the estimating and estimated persons’ religiosities and combination thereof. This demonstrates the importance of continuity of (non)religious belief because lower estimate accuracy has been observed in discontinuity situations. (3) There was no statistically significant difference of estimates between generations, yet the relationship demonstrated in the case of the interaction is primarily notable in that Roman Catholic parents incorrectly estimated their nonbeliever children to be Roman Catholics as well., Jan Váně, Veronika Hásová., and Obsahuje použitou literaturu

Description:
The process of political socialization, as shown by numerous findings, is characterised as the transmission of political action and behaviour through the generations. In connection with the political changes the Czech Republic experienced since 1945, not only the prospect of generational continuity but also discontinuity come into consideration. The article deals with the influence of parents and other socialization factors on political self-identification in the Czech population. It focuses mainly on the major age groups: young people up to the age of 29, the younger middle generation of 30-44 years, the older middle generation of 45-59 years and individuals aged 60 years or older, and their parents. The starting point of the considerations is the theory of social change and the interconnection of political socialization on the micro and macro levels. The paper analyses the circumstances of socialization and its effects on political orientation in a representative sample of Czech population (N = 522). The basis for determining the impact of socialization was set as the intensity of interest in political events together with the main resources affecting political orientation such as self-education and reading, followed by parental influence. The ratio of father’s and mother’s communist orientation plus their interest in politics accounted for the other socialization factors. Political background of the respondents was compared with their self-identification on the left-right political scale. Correlation analysis helped highlight the significance of father’s influence, rather than mother’s, in the process of political socialization. It also showed an overall negative impact of parental political discussion on the formation of left-right orientation. ANOVA analysis demonstrated a strong relationship between socio-occupational status and political inclusion. This inclusion effect was more frequent among left-wing labourers and pensioners and right-wing entrepreneurs, tradesmen, students and apprentices. Not only social background but also age signalled significant differences in opinions. The youngest generation as a whole relates to the right wing of the political spectrum. At the same time, the generation of 60+ is inclined to the left of the centre. As a matter of fact, this group, more than other age groups, is interested in political events and is deeply involved in political discussions. The young generation manifests itself in both directions. Parents’ political socialization actions towards their children induced agreement with parental political orientation only to a lesser extent. The study also dealt with two influences, sometimes mutually supportive and other times competing, namely parental socialization influence, political and economic conditions. Attitudes to social and political situation differed between age groups. The influence of society- -level circumstances is more significant than that of parental political socialization. It was possible to observe political continuity between the generations of 60+, or even their parents, and the older middle generation aged 45-59. When there is mostly continuity between them and their children then discontinuity tends to arise between them and their parents. The distribution of political orientation reveals a dynamic field. Attitudes to changes in society vary between generations as well. During the shaping of political orientation, the influence of social and political conditions is more decisive than political action, no matter how good its intentions are. This confirms the concept of political socialization as a way in which individual socialization interacts with one’ssocial position due to various social factors., Ján Mišovíč., and Obsahuje použitou literaturu
