Does an ant-dispersed plant, Viola reichenbachiana, suffer from reduced seed dispersal under inundation disturbances?
2008
Many plant species use ants as seed dispersers. This dispersal mode is considered to be susceptible to disturbances, but the effect of natural, small-scale disturbances is still unknown. We investigated how small-scale disturbances due to inundation affect seed dispersal in Viola reichenbachiana, a dominant myrmecochorous herb in riparian forests. Inundation disturbances were high in depressions and low on hillocks of the forest floor. We found that V reichenbachiana was similarly abundant at highly and less disturbed sites, contrary to other, non ant-dispersed species. We also found that the motivation of ants to disperse seeds was higher at highly disturbed sites. Nevertheless, the number…
Changes in body mass and hormone levels between wintering and spring staging areas in Dark-bellied brent geese Branta bernicla bernicla
2006
International audience; Wintering migratory geese generally replenish protein stores lost during migration before building up their fat stores (Gauthier et al. 1992). Dark-bellied brent geese Branta bernicla bernicla winter mainly along the coasts of France, England and the south-western part of the Netherlands, and stage from March till late May mainly in the Wadden Sea, stretching from the northern Netherlands to Denmark (Ebbinge et al. 1999). During spring, geese accumulate body stores needed both for their long-distance migration to the breeding grounds and for reproduction (Spaans et al. 1993, Ebbinge and Spaans 1995). Dark-bellied brent geese, migrating about 5000 km between the winte…
Dysarthria in acute ischemic stroke: lesion topography, clinicoradiologic correlation, and etiology.
2001
Background and purpose: Although dysarthria is a frequent symptom in cerebral ischemia, there is little information on its anatomic specificity, spectrum of associated clinical characteristics, and etiologic mechanisms. Methods: An investigation of 68 consecutive patients with sudden onset of dysarthria due to a single infarction confirmed by MRI or CT was conducted. Results: Dysarthria was associated with a classic lacunar stroke syndrome in 52.9% of patients. Isolated dysarthria and dysarthria–central facial and lingual paresis occurred in 2.9% (n = 2) and 10.3% (n = 7), respectively. Dysarthria–clumsy hand syndrome was observed in 11.7% (n = 8) of patients and associated with pure motor …
Progressive multifocal encephalopathy in a patient with non-Hodgkin follicular lymphoma
2020
Progressive multifocal leukoencephalopathy (PML) is a rare and often fatal demyelinating disease of the central nervous system caused by John Cunningham virus (JCV). We present a case report of patient with non-Hodgkin follicular lymphoma, who developed PML after hematopoietic stem cell transplantation and rituximab-bendamustine therapy. JCV DNA was proven both in peripheral blood and cerebrospinal fluid. Patient with 4 years history of follicular lymphoma presented with progressing weakness in the right arm and leg and postural instability. Magnetic resonance imaging scans showed bilateral hyperintense lesions in the cerebellum and centrum semiovale consistent with findings in PML. JCV DNA…
Live-in migrant care worker arrangements in Germany and the Netherlands. Motivations and justifications in family decision-making
2019
Private households in ageing societies increasingly employ live-in migrant carers (LIMCs) to care for relatives in need of 24/7 care and supervision. Whilst LIMC arrangements are a common practice in Germany, they are only recently emerging in the Netherlands. Taking this development as a starting point, this study uses the countries’ different long-term care (LTC) regimes as the analytical framework to explore and compare the motivations and justifications of German and Dutch family carers who opt for an LIMC arrangment. Findings show that Dutch and German LTC regimes impact differently the decision-making processes of families, as well as on patterns of justification, through a combinatio…
EAGLE 2006 - Multi-purpose, multi-angle and multi-sensor in-situ and airborne campaigns over grassland and forest
2009
EAGLE2006 – an intensive field campaign for the advances in land surface hydrometeorological processes – was carried out in the Netherlands from 8th to 18th June 2006, involving 16 institutions with in total 67 people from 16 different countries. In addition to the acquisition of multi-angle and multi-sensor satellite data, several airborne instruments – an optical imaging sensor, an imaging microwave radiometer, and a flux airplane – were deployed and extensive ground measurements were conducted over one grassland site at Cabauw and two forest sites at Loobos and Speulderbos in the central part of the Netherlands. The generated data set is both unique and urgently needed for the developmen…
Introduction. The Global Old-Age Care Industry. Tapping into Care Labor Across and Within National Borders
2021
A few weeks after the first COVID-19 infections were diagnosed in Germany, NGOs and experts in the field of old-age care warned of acute bottlenecks in the provision of care for older Germans. They feared that care workers from Eastern Europe who were travelling back to their home countries might not be able to return to Germany due to the closure of borders. As a result, up to 200,000 migrant care workers could be missing after Easter. The weekly German magazine Der Spiegel quoted one NGO’s spokesperson saying: “We already had a shortage of care workers, the crisis has been here for a long time.” Another NGO’s spokesperson was particularly concerned about older people in need of care who w…

O śląsko-małopolskich sporach granicznych w okresie międzywojennym
2017
Celem artykułu jest próba przedstawienia relacji Górnego Śląska z Małopolską i Krakowem w okresie międzywojennym. Relacje te rozwijały się na kilku płaszczyznach: gospodarczej, społecznej, kulturowej. Artykuł niniejszy dotyczy ich pewnego wycinka, a mianowicie śląsko-małopolskiego sporu granicznego jaki wywiązał się między środowiskami politycznymi obu regionów o przywództwo i dominację na obszarze Polski południowej. Podstawową bazę źródłową artykułu stanowi prasa, przeważnie krakowska, warszawska, śląska, nigdy dotąd w takim stopniu nie wykorzystana. Kwestia zasadnicza niniejszego studium sprowadza się do pytania, jakie były źródła i przyczyny opisywanego sporu , jakie czynniki decydowały…
