To answer this question we estimate a version of the Burdett-Mortensen search equilibrium model and analyze how workers’ search behaviour responded to these reforms. We try both nonparametric and fully-parametric estimation methods and identify the cases in which the nonparametric approach cannot be applied. We find that the entitlement reforms are largely responsible for the increase of unemployment among unskilled workers

We use long-term panel data from Germany and apply di fferent regression models, based on household covariates and previous-year equivalence income, to classify a household as vulnerable or not. Predictive performance is assessed using the Receiver Operating Characteristics (ROC), which takes account of false positive as well as true positive rates. Estimates based on cross-sectional data are much less accurate than those based on panel data, but for Germany, the accuracy of vulnerability predictions is limited even when panel data are used. In part this low accuracy is due to low poverty incidence and high mobility in and out of poverty

A protective role of silicon in mosses under abiotic stress?
No full textIm letzten Jahrzehnt haben viele Publikationen Silizium als förderliches oder gar essentielles
Element im Pflanzenbau besprochen. Dies gilt vor allem für einige Nutzpflanzen, wie zum Beispiel Zea mays oder Oryza sativa. Diese und weitere Studien verbanden pflanzenverfügbares
Silizium mit Resistenz gegen Dürre, Schwermetallstress und Pathogene. Bisher wurde allerdings
nicht viel über die Rolle von Silizium in Moosen publiziert, obwohl einige Spezies bis zu 10%
Siliziumdioxid in der Trockenmasse beinhalten.
Die durchgeführten Experimente versuchten den Einfluss von pflanzenverfügbarem Silizium, in
der Form von Natrium-Orthosilikat, auf die Stressreaktion von Moosen, zu erklären. Der Modelorganismus Physcomitrella patens (Hedw. Syn. Aphanorhegma patens) und die schwermetalltolerante Spezies Pohlia drummondii (C. Müll.) Andrews, wurden untersucht. In drei Experimenten
wurden die Moose auf festen, ursprünglich kupferfreien, Medien kultiviert. Die Hälfte der Petrischalen wurde mit 0,5 mM Natrium-Orthosilikat behandelt und die andere Hälfte wurde siliziumfrei belassen. Im ersten Experiment lag der Fokus auf der Kupferbehandlung mit CuCl2, welches den Medien in Konzentrationen von 0,1, 1 und 10 mM zugefügt wurde. Im zweiten Experiment wurde die Hälfte der Pflanzen mit UV-B Strahlung behandelt, jeweils 10 Stunden am Tag,
beginnend nach der vierten Woche Kultivierung. Im letzten Experiment wurden die Moose mit
0,2, 0,4 und 0,6 Osm NaCl behandelt, um Salzstress zu untersuchen. Die Kulturen wurden jede
Woche fotografiert und die Pflanzen wurden nach sieben Wochen geerntet. Um ausschlaggebende Beweise für die Verbindung von Silizium und Überleben, beziehungsweise Gesundheit der
Pflanze zu finden, wurden Bildanalysen, Spektrofotometrie, Sauerstoffradikalfärbung (ROS) und
Zellvermessungen durchgeführt.
Im Kupferexperiment führte die Si-Behandlung zu einer Abnahme des Kupfergehalts im Protonema der mit 1 mM Cu behandelten P. drummondii Proben. Im UV Experiment führte Si in Kombination mit UV-B Strahlung zu einer starken Biomassezunahme bei P. drummondii. Im Fall von
P. patens war die Biomasse der gleichen Behandlung gleich hoch wie in der Kontrolle, während
die UV Behandlung eine geringere Biomasse aufwies. Im Salinitätsexperiment lagen die mit 0,4
Osm NaCl behandelten P. patens Kulturen in ihrer Biomasse mit den Kontrollkulturen gleichauf,
wurden aber von den Si-behandelten und den 0,2 Osm NaCl/0,2 Osm NaCl & Si behandelten
Proben übertroffen. In diesem Falle, nahm die Biomasse auch mehr zu, als vergleichsweise bei P.
drummondii. Dies unterstützt die Hypothese, nach der P. patens eine höhere Salztoleranz hat, als
so manche andere Moose.Within the last decade, multiple papers addressed the topic of silicon as beneficial or even essential element in plant nutrition for selected crops like Zea mays or Oryza sativa. These and other
studies linked plant available silicon to drought tolerance, heavy metal stress tolerance and
pathogen defense. Yet there is not much published on the role of silicon in bryophytes, even
though some species contain up to 10% of silicon dioxide in biomass.
The conducted experiments sought to explain the influence of plant available silicon, provided as
sodium orthosilicate, on stress response in bryophytes, in this case the model organism
Physcomitrella patens (Hedw., syn. Aphanorhegma patens) and the heavy metal tolerant Pohlia
drummondii (C. Müll.) Andrews. In three experiments the mosses were cultivated on solid, initially copper free media, half of the petri dishes with 0.5 mM sodium orthosilicate and the other
half without additional silicon. The first experiment focused on Cu treatments with added concentrations of 0.1, 1 and 10 mM CuCl2. In the second experiment half of the plants were treated
with UV-B radiation for 10 h a day after the fourth week of cultivation. In the last experiment,
the mosses were treated with 0.2, 0.4 and 0.6 Osm NaCl to look at stress caused by salinity. Images of the cultures were taken every week and the plants were harvested after a period of seven weeks. Image analysis, spectrophotometry, staining of reactive oxygen species (ROS) and cell
measurement were employed to find decisive evidence linking silicon to the viability and general fitness of the plant.
In the Cu experiment, Si treatment led to a decrease of Cu accumulation in the protonemata of P.
drummondii in 1 mM Cu treated samples. In the UV experiment, Si led to a strong increase in
biomass in combination with UV treatment of P. drummondii. In case of P. patens, the biomass of
the same treatment was equal to the control, while the UV treatment yielded lower biomass. The
0.4 Osm NaCl treated P. patens performed on par with the control, but was outperformed by the
Si treated and both 0.2 Osm NaCl/0.2 Osm NaCl & Si treated samples in the salinity experiment.
It also gained more biomass than the P. drummondii samples of the same treatment, supporting
the hypothesis that P. patens is more salt tolerant than some other mosses
Hybrid simulation of wake vortices of landing aircraft in a turbulent environment
No full textWake-vortex evolution during landing of a long range aircraft is investigated in a turbulent environment. The simulations cover final approach, touchdown on the tarmac, and the evolution of the wake after touchdown. An ambient turbulent crosswind and headwind field is generated in a pre-simulation. The wake is initialized using a RANS-LES coupling approach. The further development of the vortical wake is investigated by large-eddy simulation until final decay. Strong three-dimensional deformations appearing after touchdown and linkings with the ground are studied. The downwind vortex is strongly advected with crosswind and decays quickly. The interaction of plate line disturbances and end effects in a turbulent environment leads to irregular decay pattern
On the Problem of Stephan Javors’kyj’s Homiletics
No full textThe author analyses the content of the unique manuscript which contains at least 70 unpublished sermons written by Stephan Javors’kyj when he was still in Ukraine (ms. 1592 of the Russian state historical archive in S. Petersburg). She tries to explain some latent significations of his homilies and underlines how urgent it is to undertake scientific publications of these and other works by Javors ’kyj, which would allow to give a completely different image of this outstanding personality of Ukrainian literary Baroque.Авторка аналізує зміст унікальної збірки, яка містить щонайменше 70 неопублікованих гомілій Стефана Яворського (рукопис № 1592 Російського державного історичного архіву в Санкт-Петербурзі), намагається пояснити деякі приховані значення його проповідей та наголошує на потребі сучасного видання праць Яворського, що дозволило б подати цілком відмінний образ цієї видатної особистості в українському літературному Бароко
