The well of the Stroke–Ornamented Ware culture, discussed in this paper, was discovered at Konary in August 1999. The site lies near the well–known complex of sites at Brześć Kujawski (some 8 km to the west). The available findings show that the well was built in the early phase of the use–life of a large settlement composed of trapezoidal houses. The well, which was 4.5 m deep, was dug in hard moraine clay. The bottom of the well yielded a characteristic amphora lavishly ornamented with a stroke patternin geometric arrangement, dating to phase IV of the Stroke-Ornamented Ware culture after M. Steklá–Zápotocká. Though discoveries of wells have already been recorded in the Linear Pottery culture, the well from Konary is by far the most credible and remarkable discovery. and Studna z období kultury s vypíchanou keramikou, jež je pojednávána v článku, byla odkryta v Konarech v srpnu 1999 nedaleko známého komplexu lokalit u obce Breść Kujawski. Studna byla zřízena v počáteční fázi života rozsáhlého sídliště s trapezovitými domy. Byla vykopána v tvrdém morénovém jílu do hloubky 4,5 m. Na dně studny ležela typická amfora bohatě zdobená vypíchanými geometrickými vzory, datovaná do IV. fáze kultury s vypíchanou keramikou podle M. Steklé–Zápotocké. Ačkoli známe studny již z kultury s lineární keramikou, studna z Konar se díky nálezovým okolnostem řadí k objektům s nejvyšší vypovídací hodnotou.
One of the current goals of research concerning the Czech national rebirth is clarification of the coexistence of Czech and German cultures in the Czech lands during the first half of the nineteenth century. V. J. Tomášek (1774–1850), one of the most important musicians of this period, was a Czech not only officially: he felt himself to be Czech, and supported the Czech language and culture. However, as an adult he probably spoke and wrote more in German, as confirmed by preserved writings of his such as correspondence, his autobiography, reviews, a catalogue of pupils, and his last will and testament. Moreover, in his vocal compositions, which form the main part of his output, most of the texts he set to music are in German. Tomá‰ek himself commented on his relation to the Czech language and Czech culture very briefly; testimony to his warm but modest patriotism is found in recollections written by his brother-in-law K. V. Hansgirg and his friend P. A. Klar. Tomášek’s cultural and national orientation is also documented by his contacts with Czech patriots and his work with the magazine Ost und West, which was intended for the Czech and Czech-German intelligentsia. Characteristic of Tomášek is patriotism attached to a geographical territory, whereby what was most important was his relationship to the land, its history, and its culture.
A review of West Palaearctic species of the genus Eloeophila Rondani, 1856 is presented. Three species are redescribed, viz. E. czernyi (Strobl in Czerny & Strobl, 1909), E. laciniata (Edwards, 1928), and E. pusilla (Kuntze, 1920). A lectotype of the latter is designated. Eloeophila albofascia (Alexander, 1975) is established as a new junior synonym of E. apicata (Loew, 1871). Descriptions are provided of E. bipartita sp. n. (North Italy), E. delmastroi sp. n. (North Italy), E. lucasi sp. n. (South Italy and Sicily), E. maroccana sp. n. (Morocco, Spain), E. martinovskyi sp. n. (South Italy), E. minor sp. n. (Czech Republic, Slovakia), E. pectinistylus sp. n. (Spain), E. punctulata sp. n. [Cyprus, Greece (Crete)], E. sparsipunctum sp. n. (Bulgaria), and E. tigricosta sp. n. (Spain). A key to males of all West Palaearctic species is presented.
To understand the evolution of insect gut symbionts it is important to determine how they are passed on to the next generation. We studied this process in Erwinia species bacteria that inhabit the gut of western flower thrips, Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae). This is a polyphagous herbivore and a world-wide pest in agricultural crops. With bacteria in the gut, the thrips larval development time can be shorter and its oviposition rate higher compared to bacteria-free thrips. Bacteria are not directly transmitted from mother to offspring, but larvae acquire bacteria from the leaves right after they hatch. These gut bacteria are present on the leaves on feeding sites used by other thrips before the larvae arrive, probably because these other thrips have deposited bacteria via faeces or regurgitation. In this study we addressed the question whether the transmission route of symbiotic bacteria influences the thrips feeding behaviour, and determined the feeding and oviposition preference of thrips, by giving them a choice between leaves with and leaves without prior grazing by other western flower thrips. This was studied for thrips with and thrips without gut bacteria. Young larvae prefer to feed on leaves that where grazed before by other thrips and females prefer to oviposit on these grazed leaves. These results are in contradiction to earlier studies that have found that thrips larvae fitness is lower on thrips damaged plants than on clean plants. This behaviour does however promote the establishment of gut bacteria in the thrips. The factors determining the preference for thrips-damaged leaves may be the physical leaf damage or odours that are produced by the plant, the bacteria or both.
This paper discusses the strengths and weaknesses of pan-European datasets, in particular ECHP and EU-SILC, for research in housing. Although ‘housing’ is a complex topic when studied from a European comparative perspective, I argue that there is no inherent reason why housing should be less amenable to cross-national research than other equally complex topics in comparative social science research, such as research into family change and stability, or the impact of educational systems on social stratification. Given appropriate theory, conceptualisation and contextualisation, along with strong methodologies, meaningful and informative research in housing with ECHP and EU-SILC are possible. There are however a number of limitations, which are mainly related to the fact that both datasets are geared towards the ‘production’ of a ‘system of social indicators’ informing European and national governments. Because of these limitations, ECHP and in particular EU-SILC are less attractive and less useful for academic research then they could potentially be.
The aim of this study was to check what decide about breeding success in red- backed shrike Lanius collurio: nest-site concealment or parent’s aggressive behaviour. The study was carried out in eastern Poland in 1999–2003, on study plot consisted of 855 ha of extensively agricultural landscape. The effect of nest site concealment and defence of brood by parents on breeding success was determined. In observations only natural nests were used. During the two of 10 days periods after commence of egg laying, no effect of index nest concealment and index of parents aggressiveness was observed. However, in first seven days of life of nestlings, was noticed that breeding success was depended on aggressiveness of parents, in relation to index nest concealment. The results showed behavior (aggression) as an important factor in breeding success of the red-backed shrike.
This cross sectional study focused on how Postural Stability (PS) indicators: body sway deviation (BSD) and body sway velocity (BSV), change with age and their association with levels of social and physical activity. Observational study: 80 older adults (aged: 60-96) were purposefully recruited from two sources: the University of the Third Age (TAU) (n = 35) and a residential care home (CH) (n = 45). Differences in the indicators of PS, approximated through Centre of Pressure (COP) measurements, were assessed by the Romberg Stance Test (Test A) subsequently repeated on 10 cm foam surface (Test B), using a Kistler Dynamometric Platform. The RCH Group was older, had higher BMI and was less socially and physically active, showed more body sway in all indicators compared to TAU group. For all participants body sway velocity (BSV) was significantly correlated with age. The strength of correlation of body sway deviation (BSD) with age was also significant but not as strong. The findings indicate in line with previous studies that deterioration in BSV is associated with poor PS more than deterioration in BSD. and J. Jančová Všetečková, N. Drey
Epileptic afterdischarges (ADs) elicited by electrical stimulation of sensorimotor cortical area were used as a model to study the role of neurotransmitter systems in cortical seizures in three age groups of developing rats. Drugs augmenting inhibition mediated by GABAA receptors were found to suppress ADs in all age groups, their activity was usually more marked in younger than in 25-day-old rat pups. Drugs potentiating GABAB receptors exhibit lower efficacy and more complicated developmental profile than GABAA-ergic drugs. Effects of an antagonist of GABAB receptor – marked prolongation of ADs in all three age groups – suggest an important role of GABAB receptors in arrest of cortical seizures. Drugs affecting glutamate receptors exhibit variable effects, usually better expressed in older animals than in 12-day-old ones. No specific role for ionotropic as well as metabotropic glutamate receptors could be predicted. Activation of adenosinergic inhibitory modulatory system also exhibited anticonvulsant action in the present model. All three neurotransmitter systems probably participate in mechanisms of generation, maintenance and arrest of cortical seizures., P. Mareš, H.
