In this paper I have introduced one case of modification of articulation at the word-boundary, i. e. the assimilation, which regularly takes place in Dutch, but is impeded in Czech. In Dutch the assimilation of [s] in front of [j] is the result of coarticulation, applied in order to reduce the articulatory effort. It is, however, not an isolated phenomenon, but it is connected with the not clearly defined phonological and phonetic opposition of [s] and [š]. In Czech, despite the presumption that the coarticulation of the [s] in front of [j] also is possible, it is not audible for the speakers as modification, and - most importantly - it does not yield assimilation of the former to the latter, i. e. the realization of [š]. In our opinion the constraints are complex, in the first place we should point to the distinctive role of the /s/ and /š/ in the whole system. The perceptual segmentation in Czech, moreover, is ruled by the distribution of word-stress at the initial syllable of the word (after a pause); this brings about the hyperarticulation of the syllable, so that no need is felt to reduce the articulation. Because of the typological difference between Czech and Dutch, as respectively inflective and not-inflective languages, the phonetic phenomena at the word-end can be very significant and should be examined further.
Motivated by Vityuk and Golushkov (2004), using the Schauder Fixed Point Theorem and the Contraction Principle, we consider existence and uniqueness of positive solution of a singular partial fractional differential equation in a Banach space concerning with fractional derivative.
Examinations of 29 specimens of the catfish Liobagrus reini Hilgendorf (Siluriformes: Amblycipitidae), a species endemic to Japan, collected from the Sho River, Toyama Prefecture, in central Honshu, revealed the presence of four species of helminth parasites: Plagioporus honshuensis sp. n. (Trematoda), Rhabdochona coronacauda Belouss, 1965, H. japonica Moravec, 1975 and Mexiconema liobagri sp. n. (all Nematoda). The new opccoelid trematode P. honshuensis is characterized mainly by the extent of vitelline follicles, the size ratio of the suckers (1 : 1.7-2.1), the situation of testes near the middle of the body and by the structure, size and shape of the cirrus sac. Allopodocotyle Pritchard, 1966 is considered a junior synonym of Plagioporus Stafford, 1904. The males of R. japonica are described for the first time and conspeciftc females are redescribed; this species is a specific parasite of L. reini. The principle hosts of R. coronacauda are cyprinids and, therefore, its finding in the catfish may indicate an accidental infection; L. reini represents a new host record. M. liobagri (only females were found) from the host’s abdominal cavily is the second known species of this dracunculoid genus, being characterized by the position of the excretory pore and the number (1) of caudal processes in the female. The recorded helminths are briefly described and illustrated and problems of their systematic status are discussed.
The number of children in shared custody has been growing slowly in the CR. Today shared custody presents about 8 % of divorce cases with dependent children decided by courts. Despite this trend, there is a lack of research on how shared custody is practiced and experienced by Czech parents. The aim of this paper is to partially fill this gap. In the paper I ask how shared custody is related to the disruption of traditional gender ideology and performance of paternal and maternal roles and gender inequalities between partners. The analysis is based on 13 in-depth interviews with couples (mothers and fathers separately) who have shared custody. The analysis indicated that even if shared custody may be considered to be a tool for disrupting gender stereotypes and gender inequality between parents, it proved to be associated both with the confirmation and disruption of gender stereotypes associated with fatherhood and motherhood. While certain aspects of the practices and culture of shared custody are associated with “undoing gender”(especially regarding fatherhood), in other aspects it enhances and reproduces the gender power inequality between ex-partners and traditional expectations associated with parental roles.

The changes of runoff in the middle reaches of the Yellow River basin of China have received considerable attention owing to their sharply decline during recent decades. In this paper, the impacts of rainfall characteristics and land use and cover change on water yields in the Jingle sub-basin of the middle reaches of the Yellow River basin were investigated using a combination of statistical analysis and hydrological simulations. The Levenberg Marquardt and Analysis of Variance methods were used to construct multivariate, nonlinear, model equations between runoff coefficient and rainfall intensity and vegetation coverage. The land use changes from 1971 to 2017 were ascertained using transition matrix analysis. The impact of land use on water yields was estimated using the M-EIES hydrological model. The results show that the runoff during flood season (July to September) decreased significantly after 2000, whereas slightly decreasing trend was detected for precipitation. Furthermore, there were increase in short, intense, rainfall events after 2000 and this rainfall events were more conducive to flood generation. The “Grain for Green” project was carried out in 1999, and the land use in the middle reaches of the Yellow River improved significantly, which make the vegetation coverage (Vc) of the Jingle sub-basin increased by 13%. When Vc approaches 48%, the runoff coefficient decreased to the lowest, and the vegetation conditions have the greatest effect on reducing runoff. Both land use and climate can change the water yield in the basin, but for areas where land use has significantly improved, the impact of land use change on water yield plays a dominant role. The results acquired in this study provide a useful reference for water resources planning and soil and water conservation in the erodible areas of the middle reaches of the Yellow River basin.
