- Language:

- Description:
- Migration research is an emerging field in the Czech Republic and data collection poses many methodological challenges. Some of the problems are universal for the research of other hard-to-reach populations. Other problems are, on the contrary, unique, applying only for the research of immigrants and could be country specific. This article focusses mainly on the quantitative research of immigrants where the issue of sampling problem is of major concern. The aim of the article is to address the issue of sampling immigrants in the context of the Czech Republic. In the first part of the article, there is a review of existing methodological approaches to researching immigrant populations. The focus here is on potential problems when applying particular methods in the Czech context. The second part of the article is dedicated to a review of four major Czech sample surveys of immigrants that are compared in terms of their methodology and basic results

- Subject:
- attitude constraints, political knowledge, attitudes to politics, and HM
- Language:
- Czech
- Description:
- The aim of this study is to explore the sources of attitude constraints regarding the role of government in the economy, and to find out whether the sources of these constraints are the same as in Western democracies. Use is made of Converse’s approach to conceptualize attitude constraint where an individual’s belief system is seen to be a configuration of attitudes and values characterized by a functional interdependence, or constraint. This constraint may be interpreted in terms of the probability of being able to predict one attitude having knowledge of another. In this study, there is a review of the sources of attitude constraint and related measurement issues. Using ISSP 2006 (Role of Government module) an analysis of attitudinal constraints is presented using two attitudinal scales. This research confirms that the sources of attitude constraint in the Czech Republic are similar to those observed in Western Europe and the USA. Specifically, class, education, and other social-demographic variables are shown to have very limited effects. Moreover, Converse’s contention that attitude constraints are strongly determined by political involvement, political knowledge, or party identification is also shown to be valid for Czech society.

- Subject:

- Language:

- Description:
- The mite family Ascouracaridae Gaud et Atyeo, 1976 contains large-sized mites (mostly > 1 mm) which live inside the quills of birds of several orders. To date, no representative of this family has been found associated with the order Strigiformes (owls). In this paper, a new species of this family, Cystoidosoma hermaphroditus sp. n., is described from the tropical screech owl, Megascops choliba (Vieillot) (Aves: Strigiformes) from Brazil. This species is unique in having an external spermaduct, a primary duct and a rudimentary bursa copulatrix present in males. This is the first astigmatan feather mite described from the order Strigiformes in this country. A key to adults of the genus Cystoidosoma Gaud et Atyeo, 1976 of the world is presented., Fabio Akashi Hernandes, Barry M. OConnor., and Obsahuje bibliografii

46. Damselflies (Zygoptera) as paratenic hosts for Serpinema trispinosum and its report from turtle hosts from Oklahoma, USA

- Description:
- Third-stage larvae of the nematode Serpinema trispinosum (Leidy, 1852) were collected from the midgut of four of five species of adult damselflies (Zygoptera) from a non-irrigated restored semipermanent wetland located in Stillwater, Oklahoma, USA. Of the four infected damselfly species, prevalence and mean abundance was highest for the southern spreadwing, Lestes disjunctus australis Walker (10%, 0.2 ± 0.8) and lowest for the familiar bluet, Enallagma civile (Hagen) (2.5%, 0.04 ± 0.3); whereas mean intensities were lowest for the citrine forktail, Ischnura hastata (Say) (1.5 ± 0.5) and the eastern forktail, Ischnura verticalis (Say) (1.0 ± 0). This is the first record of larvae of S. trispinosum from damselflies. Serpinema trispinosum adults have been reported from 18 species of North and Central American freshwater turtles, whereas microcrustaceans such as copepods serve as intermediate hosts and snails, fish and amphibians serve as paratenic hosts in this nematode's life cycle. However, dietary studies of the 18 species of freshwater turtles reported as definitive hosts for S. trispinosum indicate that aquatic insects including damselflies are more commonly reported in turtle diets than are fish or amphibians. Additionally, unlike snails and amphibians, larval damselflies predominantly feed on microcrustaceans, and our observation of S. trispinosum infecting damselflies may reflect the importance of these insects as paratenic hosts. In the present study, we provide new host information and measurements for third-stage larvae of S. trispinosum from damselfly hosts along with measurements for adult male and female S. trispinosum from turtle hosts from Oklahoma, USA., Crystal M.

- Subject:
- svobodné matky and mimomanželská plodnost
- Language:
- Czech
- Description:
- Tento text se věnuje nárůstu mimomanželské plodnosti v České republice. V úvodu připomíná, že současná sociologie nabízí dvě vysvětlení, proč k tomuto trendu dochází. Prvním je tzv. teorie druhého demografického přechodu a druhým odkaz na zneužívání sociálních dávek. Tento článek nabízí další vysvětlení, proč se zvyšuje podíl žen, které rodí děti mimo manželství, a to zvláště mezi matkami s nízkým vzděláním. Data Sociální a ekonomické podmínky mateřství totiž naznačují, že rostoucí mimomanželskou plodnost je možné do značné míry připsat osamělému mateřství, a to zvláště v nižších sociálních vrstvách. V posledním sledovaném období neměla v době porodu stálého partnera již více než polovina matek se základním vzděláním; muži se základním vzděláním mají rovněž po rozchodu s partnerkou velmi omezené kontakty se svými dětmi.

- Description:
- Lepeophtheirus simplex Ho, Gómez et Fajer-Avila, 2001 is a parasite of Sphoeroides annulatus (Jenyns), an economically important fish species, with potential for aquaculture, in northwestern Mexico. The goal of this study was to describe the developmental stages under experimental conditions and seasonal fecundity of this parasite on wild fish. There are two naupliar, one copepodid, two chalimus and two pre-adult stages preceding the adult of L. simplex. The results support previous findings, which point out that the life cycle of the caligid copepods includes only six post-naupliar stages. The generation time from egg extrusion to adult for L. simplex was approximately 10 days at 22 °C. The body length of the ovigerous females ranged between 2.2 and 4.1 mm, and its fecundity between 12 and 36 eggs per string. Fecundity was negatively correlated with the egg size and positively correlated with the egg string length. Our data did not reveal significant differences in fecundity among sampling months, but ovigerous females were significantly larger in March (when water temperature was 22 °C) than in June and July (when water temperature was 30 °C). To some extent, our fecundity results contrast with those found in species of sea lice from higher latitudes. Undoubtedly, biological information on different species of sea lice from different environmental conditions will enhance our understanding of their infection strategies and will be valuable, given the increasing interest in marine fish farming in Mexico., Francisco Neptalí Morales-Serna, Ana Inés Rivas-Salas, Samuel Gómez, Emma Josefina Fajer-Ávila., and Obsahuje bibliografii

- Diarium, P. Václav Vojtěch Berenklau, priests' notes from Baroque Bohemia, D1, and Z004
- Language:
- Multiple languages
- Description:
- This article presents the little known diary entries of the priest P. Václav Vojtěch Berenklau († 1699) primarily from the Kladruby period of his activities (1675-1677). An attempt is also made to compare his diary with a fragment from 1662-1663 of a priest's diary belonging to P. Jan Manner in Prague and the as yet largely unexamined diary specimens from the famous P. Bartoloměj Michal Zelenka from the time he was active in Brandýs nad Labem. In addition to these diaries, the diary is also compared with notes made by the distinguished Baroque preacher and writer O. F. De Waldt.
