Language, (em)power(ment) and affective capitalism : the case of an entrepreneurship workshop for refugees in Germany
2022
Abstract This paper seeks to advance research on the nexus of language, work-related training and affective capitalism by focusing on an entrepreneurship workshop organized for newly arrived refugees in Germany. Despite the occupational orientation, the primary objective of the workshop was not establishing a business but “empowering” the participants by guiding them to adopt “an entrepreneurial mindset”. To delve deeper into this ‘will to empower’, the study brings together the perspectives of governmentality studies, ethnography, discourse studies and affect studies. To investigate in more detail the evocation of the ‘entrepreneurial mindset’, the study draws on ethnographic data collecte…
Introduction : language, work and affective capitalism
2022
Abstract This special issue contributes to scholarship on language and affective economy by exploring the role played by affect in shaping work and workers under current configurations of capitalism. We take as a starting point the observation of increased valorisation and instrumentalisation of affect in the contemporary phase of capitalism. In this editorial introduction to the special issue, we set the scene by first outlining our questions, aims and objectives. Subsequently, we situate the contribution made by this issue in a larger social theorisation of affect and capitalism, particularly the notion of affective capitalism, and reflect on how this theorisation can contribute to sociol…
A language socialisation perspective on Swedish immersion in Finland : Students, teachers, and parents as key actors
2022
Abstract This retrospective review applies a language socialisation perspective in examining the findings of a four-year research project on Swedish immersion in Finland. Findings from nine sub-studies within the project are reported with a point-of-view from three key actors’ (teachers, students, and parents) language socialisation processes. Results show that a special feature of immersion teacher socialisation is its continuous attention toward the additive multilingual nature of immersion education, which requires sustained attention to multilingual language use and development. Students in Swedish immersion are socialised into the use of multiple languages in school and act as socialis…
The changing schoolscape in a Szekler village in Romania: signs of diversity in rehungarization
2015
In this paper, we explore the connections between a linguistic landscape and language ideologies in an elementary school in a village within the Hungarian region of Szeklerland in Romania. This ‘schoolscape’ is analysed as a display or materialization of the ‘hidden curriculum’ regarding the construction of linguistic and cultural identities. We draw on fieldwork carried out in 2012 and 2013 and examine two dimensions of change in progress: (1) changes in the use of Hungarian and Romanian as languages of teaching and learning and as languages of written administration; and (2) changes in the display of these languages in the schoolscape. Since 1990, there has been a tendency towards rehunga…
Genome wide linkage disequilibrium and genetic structure in Sicilian dairy sheep breeds
2014
Background The recent availability of sheep genome-wide SNP panels allows providing background information concerning genome structure in domestic animals. The aim of this work was to investigate the patterns of linkage disequilibrium (LD), the genetic diversity and population structure in Valle del Belice, Comisana, and Pinzirita dairy sheep breeds using the Illumina Ovine SNP50K Genotyping array. Results Average r2 between adjacent SNPs across all chromosomes was 0.155 ± 0.204 for Valle del Belice, 0.156 ± 0.208 for Comisana, and 0.128 ± 0.188 for Pinzirita breeds, and some variations in LD value across chromosomes were observed, in particular for Valle del Belice and Comisana breeds. Ave…
Anti-inflammatory activity of berenjenol and related compounds.
2008
Berenjenol ( 1), isolated from OXANDRA cf. XYLOPIOIDES (Annonaceae), was tested on two different experimental models of inflammation. The compound showed anti-inflammatory activity in the test of acute mouse ear edema induced by TPA (54 % inhibition, 1 μmol/ear) as well as in the test of subchronic inflammation induced by repeated application of TPA (57 % inhibition, 7 × 1 μmol/ear). Moreover, while it reduced the expression of both COX-2 (65 % inhibition at 50 μM) and iNOS (80 % inhibition at 50 μM), it was not active against TNF- α and IL-1 β in murine macrophages (RAW 264.7) stimulated with LPS. Structural modification of 1 gave two derivatives, berenjenol acetate ( 2) and 3-oxo-berenjen…
Modulation of protein tyrosine nitration and inflammatory mediators by isoprenylhydroquinone glucoside.
2007
The nitration of tyrosine caused by peroxynitrite and other reactive nitrogen species is clearly detrimental for some physiological processes; however, its signalling role is still open to controversy. Among the natural phenolics known for their ability to oppose free tyrosine nitration, isoprenylhydroquinone glucoside is investigated due to its unusual structure, which contains a simple hydroxybenzene alkylated by a hemiterpenoid moiety. This hydroquinone was shown to be an effective inhibitor of peroxynitrite-induced protein tyrosine nitration in 3T3 fibroblasts. When tested on bovine seroalbumin nitration, however, the potency was reduced by half and the effect was almost abolished in th…
New functional ligands for ficolin-3 among lipopolysaccharides of Hafnia alvei.
2011
Ficolin-1 (M), ficolin-2 (L), ficolin-3 (H) and mannan-binding lectin (MBL) activate the complement system and have opsonic activity. The specificity of ficolin-3 is poorly characterized and currently limited to a few ligands only. We present new specific targets for human ficolin-3, identified among lipopolysaccharides (LPSs, endotoxin) of Hafnia alvei. The interaction was restricted to LPSs of four strains: 23, Polish Collection of Microorganisms (PCM) 1200, PCM 1203 and PCM 1205 and limited to their O-specific polysaccharides (O-specific PSs) composed of different numbers of oligosaccharide (OS) repeating units (RUs). Moreover, these LPS/ficolin-3 complexes activated the lectin pathway o…
COMPLEMENT-DEPENDENT B-CELL ACTIVATION BY COBRA VENOM FACTOR AND OTHER MITOGENS?
1974
It has been proposed that two distinct signals are required for the triggering of the precursors of antibody-forming bone marrow-derived cells (B cells): (a) the binding of antigen or of a mitogen to the corresponding receptor sites on B-cell membranes and (b) the interaction of activated C3 with the C3 receptor of B lymphocytes. There is growing evidence that B-cell mitogens and T (thymus-derived cell)-independent antigens are capable of activating the alternate pathway of the complement system (bypass). Therefore, the effect of another potent bypass inducer was investigated with regard to B-cell activation and the role of C3. Purified, pyrogen-free cobra venom factor was mitogenic for bot…
Interaction of dicaffeoylquinic derivatives with peroxynitrite and other reactive nitrogen species.
2008
Plant phenolic antioxidants, among them catechins and hydroxycinnamoyl conjugates, constitute a well defined class of inhibitors of reactive nitrogen species (RNS). To gain deeper insight in this field, we examined the effects of 3,5-di-O-caffeoylquinic acid (DCA), its methyl ester (DCE) and epigallocatechin gallate (EGCG) in nitrative and oxidative processes. These compounds were found to be strong inhibitors of the nitration of tyrosine residues induced by ONOO- in bovine seroalbumin, with their IC50 values (10-40 microM) notably decreasing in the presence of bicarbonate. When studied on the intracellular protein tyrosine nitration induced by ONOO- in cultured murine fibroblasts as well a…
