Svoboda dviženiâ tovarov v ramkah Evrazijskogo èkonomičeskogo soûza i Evropejskogo soûza : pravovoj analiz
2016
W artykule omówiono prawne aspekty swobody przepływu towarów w Unii Euroazjatyckiej i Unii Europejskiej. W tym względzie przeanalizowano podobieństwa i różnice w zakresie klasyfikacji i definicji towarów obu organizacji. Oprócz tego określono podobieństwa i różnice w odniesieniu do unii celnej i wspólnego rynku obu organizacji, a także w zakresie ograniczeń swobody przepływu unijnych i euroazjatyckich towarów. Autor przedstawił też ewentualne scenariusze w zakresie ustanowienia nowych regulacji prawnych dotyczących wymiany handlowej pomiędzy EAUG i UE
Sustainable Food vs. Unsustainable Politics in the City of Palermo: The Case of an Organic Farmers' Market
2011
The island of Sicily, Italy, and its main city, Palermo, appear an ideal scenario for sustainable food provisioning: the former being the first region in Italy for organically cultivated land, the latter Italy's fifth largest city. This article explores ideals and practices of sustainable urban food systems through an example of environmental consumer activism in Palermo. It does this by narrating the story of an organic farmers' market created by citizens and producers. The article reflects critically on understandings of food-related ‘sustainability’ held by the actors involved, showing the difficulties of operationalizing the concept for qualitative, socio-cultural research. It also high…
PRATIQUES INFO-COMMUNICATIONNELLES ET MOBILISATION SOCIALE À L'ÈRE D'INTERNET : LE CAS DE L'ITALIE
2013
Ce travail de recherche porte sur le rôle des pratiques info-communicationnelles de l'Internet dans la constitution, le développement et la mobilisation des nouveaux groupes contestataires en Italie. Avec cette approche, nous souhaitons porter notre attention sur les pratiques humaines et non pas sur les réseaux informationnels, considérés trop souvent comme le moteur déterminant du changement social. Ainsi, bien que l'essor d'Internet n'ait pas impliqué le passage à une forme de société plus émancipée, la création d'espaces informationnels indépendants représente néanmoins un enjeu politique important. L'enquête de terrain est structurée en deux volets, l'un portant sur l'analyse de la mob…
Individual habitat transitions of Atlantic herring Clupea harengus in a human-modified coastal system
2015
Published version of an article from the journal: Marine Ecology Progress Series. Also available from Inter Research. Http://dx.doi.org/10.3354/meps11103 Pelagic marine fish often display highly dynamic migration patterns. However, such movement behaviour is usually studied at the population or school level, while less is known about individual movement characteristics and habitat transitions. During March 2012 to June 2013, we used acoustic tags and moored receivers to monitor the behaviour of Atlantic herring Clupea harengus L. (N = 47) throughout a range of habitats on the Skagerrak coast in southern Norway. Five of the tagged herring entered a former lake transformed into an artificial …
Effects of acute b-alanine supplementation on countermovement jump performance after a 4x400 m fatigue protocol: A randomized, double-blind, placebo-…
2022
This study aimed to examine the effect of acute beta-alanine (β-alanine) supplementation on jump performance after a strenuous fatigue protocol. Twelve healthy young men (age 21.4±0.5 years, body height 180.2±5.8 cm, body mass 76.6±9.2 kg) volunteered to participate in this randomized, double-blind, placebo-controlled trial. The experimental group ingested 3.2 g of β-alanine (separated into two 1.6 g dosages) mixed with 23 g of glucose, whereas the placebo group ingested two dosages containing 23 g of glucose. Following the supplementation intake, participants completed a jump protocol involving countermovement jump (CMJ) and four consecutive countermovement jumps (CMJ-4). Subsequently, a 4…
The New Moral Power of Minorities
2018
The model of three interrelated social entities proposed by Gabriel Mugny to account for the role of active minorities in social innovation and change retains all its relevance and heuristic value (cf. Mugny, 1982). However, the fight of the civil rights movements of the ’60s transformed the moral perspective from which the majority regards their own behaviors towards social minorities. This resulted in an immorality judgment of discriminatory attitudes and behaviors that had long been regarded as natural. Thus a change has been effected on the relationships between majority and minority groups, providing minorities with a new moral power. As a result of such a new moral representation of p…
Orthodoxy and Evangelicalism: An Overview of Their Relationship from the Perspective of Moral Values
2021
Orthodox–Evangelical relationships are dominated by proselytism (at least in Eastern Europe and in the former Soviet Union). This is understood as church conversion practiced through unfair means among people who are already Christians, belonging to so-called “historical churches.” However, beyond it, there is a real potential for cooperation using moral values as a starting point. As there is an increasing disagreement between the Orthodox and mainline Protestant on moral values, the Orthodox and Evangelicals might increase their cooperation as they witness traditional values of Christianity. This kind of cooperation might be partially contextual, but it is based on Biblicism, which both O…
Integrin-dependent and -independent functions of astrocytic fibronectin in retinal angiogenesis
2011
Fibronectin (FN) is a major component of the extracellular matrix and functions in cell adhesion, cell spreading and cell migration. In the retina, FN is transiently expressed and assembled on astrocytes (ACs), which guide sprouting tip cells and deposit a provisional matrix for sprouting angiogenesis. The precise function of FN in retinal angiogenesis is largely unknown. Using genetic tools, we show that astrocytes are the major source of cellular FN during angiogenesis in the mouse retina. Deletion of astrocytic FN reduces radial endothelial migration during vascular plexus formation in a gene dose-dependent manner. This effect correlates with reduced VEGF receptor 2 and PI3K/AKT signalli…
The impact of the receptor binding profiles of the vascular endothelial growth factors on their angiogenic features
2013
Abstract Background Vascular endothelial growth factors (VEGFs) are potential therapeutic agents for treatment of ischemic diseases. Their angiogenic effects are mainly mediated through VEGF receptor 2 (VEGFR2). Methods Receptor binding, signaling, and biological efficacy of several VEGFR2 ligands were compared to determine their characteristics regarding angiogenic activity and vascular permeability. Results Tested VEGFR2 ligands induced receptor tyrosine phosphorylation with different efficacy depending on their binding affinities. However, the tyrosine phosphorylation pattern and the activation of the major downstream signaling pathways were comparable. The maximal angiogenic effect stim…
Pro-inflammatory effects of interleukin-17A on vascular smooth muscle cells involve NAD(P)H- oxidase derived reactive oxygen species.
2010
T cells are known for their contribution to the inflammatory element of atherosclerosis. Recently, it has been demonstrated that the Th17 derived cytokine IL-17 is involved in the pro-inflammatory response of vascular smooth muscle cells (VSMC). The aim of the present study was to examine whether reactive oxygen species (ROS) might be involved in this context. The effect of IL-17A on ROS generation was examined using the fluorescent dye 2′7′-dichlorodihydrofluorescein (H<sub>2</sub>DCF) in primary murine VSMC. IL-17A induced an increase in H<sub>2</sub>DCF fluorescence in VSMC, and this effect was blocked by the NAD(P)H-oxidase inhibitor apocynin and siRNA targeting …
