Foreign Taleovers and Wages: Theory and Evidence from Hungary

2005

This study discriminates FDI technology spillover from learning effects. Whenever learning takes time, our model predicts that foreign investors deduct the economic value of learning from wages of inexperienced workers and add it to experienced ones to prevent them from moving to local competitors. Hence, the national wage bill is unaffected by foreign takeovers. In contrast to learning, technology spillover effects occur whenever a worker with MNE experience contributes more to local firms’ than to MNEs’ productivity. In this case, experienced MNE workers are hired by local firms and the host country obtains a welfare gain. We investigate empirically wages, productivity, and worker turnove…

Granice zewnętrzne Unii Europejskiej a bezpieczeństwo narodowe państw członkowskich w kontekście współczesnego kryzysu migracyjnego

2016

Unia Europejska jest miejscem, w którym swoboda obywateli wyrażona jest poprzez możliwość przemieszania się, podróżowania, pracy,nauki lub życia w wybranym kraju UE. Realizacja tej wolności była wynikiem zniesienia kontroli na granicach wewnętrznych Unii. Jednak dla członka UE ceną tej wolności jest konieczność zapewnienia bezpieczeństwa narodowego, co sprawia, że ochronę granic zewnętrznych postrzega się jako specjalne zadanie. Unia Europejska, za pośrednictwem układu z Schengen, tworzy instytucje w zakresie ochrony granic zewnętrznych, w zakresie zapewnienia bezpieczeństwa narodowego państw członkowskich. Obecny kryzys migracyjny jest weryfikacją skuteczności tych instytucji.

Evaluation of Borderline Ovarian Tumor Recurrence Rate after Surgery with or without Fertility-Sparing Approach: Results of a Retrospective Analysis

2023

Borderline ovarian tumors (BOTs) comprise 15-20% of primary ovarian neoplasms and represent an independent disease entity among epithelial ovarian cancers. The present study (Clinical Trial ID: NCT05791838) aimed to report a retrospective analysis of the management and outcomes of 86 consecutive BOTs patients, 54 of which were at a reproductive age. All patients with BOTs undergoing surgical treatment from January 2010 to December 2017 were included. Data were retrospectively reviewed. High levels of Ca-125 were observed in 25.6% of the FIGO stage I patients and 58.3% of the advanced disease patients. Fertility-sparing surgery and comprehensive surgical staging were performed in 36.7% and 4…

Differentiation and ultrastructure of the spermatogonial cyst cells in the milkweed bug,Oncopeltus fasciatus

2002

Summary The testes of the newly hatched larva of Oncopeltus fasciatus consist of three different cell types enclosed by the tunica propria: the germline stem cells, the apical cells, and the follicle border cells which are the predecessors of the cyst progenitor cells. There are usually twelve somatically derived apical cells per follicle that no longer divide during postembryonic development. Their fine structural organization remains constant from hatching until death from old age. The apical complex cells are surrounded by at least four germline stem cells which all send cell projections toward the apical complex cells. A testicular follicle includes at least four border cells at the fir…

Reduced levels of membrane-bound alkaline phosphatase in Vip3Aa-resistant Heliothis virescens

2020

ABSTRACTThe Vip3Aa insecticidal protein fromBacillus thuringiensis(Bt) is produced by specific transgenic corn and cotton varieties for efficient control of target lepidopteran pests. The main threat to this technology is the evolution of resistance in targeted insect pests, thus understanding the mechanistic basis of resistance is crucial to deploy the most appropriate strategies for resistance management. In this work, a laboratory-selected colony ofHeliothis virescens(Vip-Sel) highly resistant to the Vip3Aa protein was used to test whether an alteration of membrane receptors in the insect midgut might explain the resistance phenotype. Binding of125I-labeled Vip3Aa to brush border membran…

Characterization of 10 trinucleotide microsatellite loci in the Critically Endangered Pyrenean yam Borderea chouardii (Dioscoreaceae)

2003

The low levels of allozymic variability found in the Critically Endangered Borderea chouardii prompted us to develop microsatellite markers to assess the genetic variability and population structure for the adequate conservation management of this species. A (CTT) n enriched partial genomic library was constructed. Ten polymorphic microsatellite loci were isolated from it, rendering 51 alleles in 47 individuals analysed. The allelic pattern observed for all of the loci with more than two alleles suggests that B. chouardii is tetraploid.

Borders on the old maps of Jizera Mountain

2019

Abstract Old maps, mainly from the period between 1890 and 1940, have been collected in the framework of the project “Old Maps of the Jizera Mountains”. These maps provide us with a complex picture, mainly of tourism, in this currently Czech–Polish territory. The territory of the Jizera Mountains was inhabited mainly by a German-speaking population on both sides of the border until 1945. Yet it is interesting to examine how the border between the two states – in those times Czechoslovakia and Germany, now Czechia and Poland – was illustrated on these old maps. This article argues that the border was not perceived as a barrier as such until later on, mainly due to the ethnic change in the bo…

Kwestia niemiecka w publicystyce emigracyjnej Ligi Niepodległości Polski po II wojnie światowej

2019

The Polish Independence League (PIL) was a political representation of Piłsudski’s followers in exile. The article presents the position of the PIL regarding the German issue after World War II. Michał Grażyński was the most outstanding expert on German issues in the ranks of Piłsudski’s followers. Before World War II, he was a long-term voivode of Silesia and a well-known politician, publicist and the president of the PIL in exile. Piłsudski’s followers repeatedly demanded that Western governments recognise the border on the Odra and Nysa Łużycka Rivers. They advocated that the western territories belong to Poland by referring to security considerations and using economic and historical ar…

Dual effect of 1-deoxymannojirimycin on the mannose uptake and on the N-glycan processing of the human colon cancer cell line HT-29.

1990

International audience; 1-Deoxymannojirimycin (dMM), a specific alpha-mannosidase I inhibitor, completely blocks the conversion of Man9-8GlcNAc2 into Man7-5-GlcNAc2 in both differentiated and undifferentiated human adenocarcinoma HT-29 cells. Besides this well known effect on N-glycan trimming, we describe here a novel effect of this inhibitor on the D-[2-3H]mannose uptake that is exclusively observed in differentiated intestinal cells, i.e. cells that display a functional apical brush border membrane. This inhibition of D-[2-3H]mannose uptake was shown to be dose-dependent and reversible. Moreover, using microsomal fractions we showed that this effect depends only on the integrity of the b…
