The Level of Dogmatism in Schizophrenia. A Comparative Analysis of Utterance Texts with the Use of the Suitbert Ertel Dogmatism Quotient

The paper describes the results of comparative research on the level of dogmatism in the utterance texts of patients diagnosed with paranoid schizophrenia (N=130) and healthy individuals (N=130). The analysis was conducted with the use of the Suitbert Ertel Dogmatism Quotient. The results indicate significant differences between these two groups.

On the convergence of the wavelet-Galerkin method for nonlinear filtering

The aim of the paper is to examine the wavelet-Galerkin method for the solution of filtering equations. We use a wavelet biorthogonal basis with compact support for approximations of the solution. Then we compute the Zakai equation for our filtering problem and consider the implicit Euler scheme in time and the Galerkin scheme in space for the solution of the Zakai equation. We give theorems on convergence and its rate. The method is numerically much more efficient than the classical Galerkin method.

Abstract

This study sought to evaluate the number of those overweight and the rate of obesity among 6- and 7-year-olds living in Poland with regard to their place of residence, the parental level of education and the number of children in the family. The analysis was based on a survey of 64 544 children (33 051 boys and 31 493 girls) living in Poland. Overweight and obesity were defined based on body mass index (BMI) using the IOTF cut-off points. To evaluate the rates of overweight and obesity occurrence in children with regard to family socio-economic status, parental level of education, the number of children in the family, and the place of residence (divided into city and village) was used. ‘Only children’ were the most likely group to be overweight or obese. These children were twice as likely to be obese as their peers living in families with four or more children. Overweight and obesity occurred more often amongst children living in cities rather than those living in rural areas. Moreover, these conditions were more frequent among children whose parents had higher levels of education. The most significant predictors of childhood overweight and obesity were the number of children in the family and the educational level of the mother

Abstract

The main objective of this study was to assess the occurrence of Chlamydia spp. in Polish swine herds by using serological, molecular, and histological methods as well as by clinical manifestation of the suspected infection when reproductive disorders were taken into account. The seroprevalence among examined animals was 5.65% (96/1698), whereas molecular assessment of the pathogen was negative (0/298). The results of our investigation showed that Chlamydia spp. infection in swine may be suspected more often based on clinical manifestation or histological examination than serological or molecular methods.
