The aim of the article is to quantify how often in leading Czech social-science journals (Československá psychologie / Czechoslovak Psychology, Pedagogika/Pedagogy, and Sociologický časopis / Czech Sociological Review) authors choose the wrong procedures to analyse quantitative data. In particular, attention is focused on the incorrect choice of statistical tests, their misinterpretation and mechanical application, and the use of effect sizes, that are so highly recommended nowadays. The basic research period was ten years, from 2005 to 2014, and for the Czech Sociological Review the period was extended back to 1995. The results of the content analysis of published articles (N=363) show that statistical tests are applied quite often to data that are not suitable for statistical tests: this is found in about one-fifth of cases in Czech Sociological Review, one-half in Pedagogy, and more than three-quarters in Czechoslovak Psychology. In addition, authors often make mechanical use of statistical methods or make incorrect interpretations (in over 40% of articles in the Czech Sociological Review over the last 10 years) and there are rarely any substantive interpretations of results (especially in Czechoslovak Psychology). Effect sizes are applied relatively often, but there are also gaps in their usage. It is clear from the results that changes are necessary both in the teaching of quantitative methodology and publishing practices in this subject area.
Research on precarious work and the working conditions of lowwage workers often stresses the role of the labour market or state institutions in either creating or exacerbating already precarious working conditions. However, it often ignores their organisational aspects. At the same time, in organisation studies there is a large body of literature that focuses on internal organisational structures but disregards working conditions. This article is based on a case study of supermarket cashiers and deals with the flexibilisation of their work. Firms use two forms of flexibility as a cost-cutting strategy: numerical and functional flexibility. Numerical flexibility divides workers into different groups according to their work contract. This enables firms to employ as much labour as they need at a particular point in time. In effect firms reduce the number of employees while intensifying the work of the employees they retain. In the case of functional flexibility the duties and responsibilities attached to a job are redefined. In this respect, I show that the duties of the cashiers in my case study are increased beyond the scope of tasks traditionally attached to this occupation and head towards the model of a universal worker. This shift leads to a decline in qualifications that, combined with technological changes, results in the degradation of work. As a result, flexibilisation processes deepen existing asymmetries in employer-employee relationships and thereby enable firms to transfer a significant amount of market risk onto the shoulders of workers. Moreover, the negotiating position of workers remains weak and their wages low.
This article focuses on the relationship between young adults’ cognitive abilities and individual partner preferences. We worked with the Preference NSZ 2017 data set, which contains data on partner preferences and the results of the National Comparative Secondary-School Exams of Czech high school graduates, and our analyses, using logistic regression, confirmed a tendency towards homophily on the level of cognitive abilities and university education. Young people with above-average results place more importance on agreement in political opinions, but do not regard the partner’s homemaking abilities or financial situation as too important. The results further show that partner preferences differ according to the education capital of the background family and according to preferred partnership arrangement. We also find significant differences in the partner preferences of men and women that reflect ideas about traditional gender roles. Women favour characteristics that relate to status, and men assign more importance to physical looks.
This article examines the issue of siblinghood in older age. The author starts by referring to sociological studies criticising the a-theoricity of empirical research in this field. She proceeds to analyse the most influential theoretical approaches used to study relationships between parents and their adult children (i.e. the theory of intergenerational solidarity and the theory/ concept of intergenerational ambivalence) and to critically assess their potential to serve as a guideline for empirical research on siblinghood and provide a framework for interpreting research findings on intragenerational/sibling relationships. The article devotes more space to the concept of ambivalence, which, the author argues, is a more appropriate approach for exploring relationships between older siblings. It also presents a basic overview of the state of empirical knowledge on adult siblinghood.
