This article deals with empirical research on poverty in Czechoslovakia from the interwar period to the present in terms of three distinct phases. First, between 1918 and 1948, considerable attention was devoted to poverty, but research possibilities modest, so that a complex mapping of the problem was not feasible. Second, during the 1948 to 1989 period, the communist regime allowed "examinations" of poverty for the purpose of depicting pre-war capitalist Czechoslovakia as an impoverished, class-divided society. A similar approach was applied to studies of Western countries during the Cold War period. Research on poverty within the socialist regime was not allowed, even after the rehabilitation of sociology as a social science. Detailed analysis of household surveys was either forbidden or the results were embargoed; only simple cross-tabulations were ever published. Third, after 1989, the opportunities for undertaking research on poverty increased dramatically due to stimulus in both the national and international arenas. Important projects were fielded leading to many studies and published articles. Statistical surveys were used to map poverty primarily in terms of income; while sociological, ethnographic and anthropological approaches were used to examine key groups affected by poverty in Czech society. Within the literature there has been to date no synthesis of the study of the nature and origins of poverty in the Czech Republic., Jiří Večerník., and Obsahuje bibliografii a bibliografické odkazy
Empruthotrema quindecima sp. n. (Monogcnea: Monocotylidae) is described from the nasal fossae of the blue-spotted fantail ray Taeniura lymma (Forsskâl, 1775) collected from the reef flats of Heron Island and Lizard Island located at the southern and northern sections, respectively, of the Great Barrier Reef in Queensland, Australia. Empruthotrema quindecima has 15 marginal loculi on the haptor which distinguishes it from the other five members of the genus which have either 13 or 14 marginal loculi. The generic diagnosis of Empruthotrema Johnston ct Ticgs, 1922 is amended to accommodate the new species, a key to species is provided and the evolution of the different configurations of the haptoral loculi within the genus is discussed.

After menopause, when estrogen levels decrease, there is room for the activity of anthropogenic substances with estrogenic properties - endocrine disruptors (EDs) - that can interfere with bone remodeling and changes in calcium-phosphate metabolism. Selected unconjugated EDs of the bisphenol group - BPA, BPS, BPF, BPAF, and the paraben family - methyl-, ethyl-, propyl-, butyl-, and benzyl-parabens - were measured by high performance liquid chromatography-tandem mass spectrometry in the plasma of 24 postmenopausal women. Parameters of calcium-phosphate metabolism and bone mineral density were assessed. Osteoporosis was classified in 14 women, and 10 women were put into the control group. The impact of EDs on calcium-phosphate metabolism was evaluated by multiple linear regressions. In women with osteoporosis, concentrations of BPA ranged from the lower limit of quantification (LLOQ) - 104 pg/ml and methyl paraben (MP) from LLOQ - 1120 pg/ml. The alternative bisphenols BPS, BPF and BPAF were all under the LLOQ. Except for MP, no further parabens were detected in the majority of samples. The multiple linear regression model found a positive association of BPA (β=0.07, p<0.05) on calcium (Ca) concentrations. Furthermore, MP (β=-0.232, p<0.05) was negatively associated with C-terminal telopeptide. These preliminary results suggest that these EDs may have effects on calcium-phosphate metabolism., J.
