O — Emmanuelle — Catherine M. Kobiecy trójgłos o seksie
No full textO — Emmanuelle — Catherine M. Three female voices on sex In the article the author analyses three literary texts — French erotic novels translated into Polish, which were written by women. They encompass: Pauline Reage’s Histoire d’O, Emmanuelle Arsan’s Emmanuelle, and the autobiography of Catherine Millet Sex Life of Catherine M. These novels represent three styles of talking about sex; namely, silence — d’O erotic metaphor, picturesequeness — Emmanuelle and talking directly — Catherine M. The authors named the sexual act and the parts of body connected with it drawing abundantly from the general repertoire of sexualisms and choosing consistently according to their life philosophy. Thus, they created their personal way of talking about sex. In the analysed instances sexual idiolect as “a code of an individual speaker” reveals the philosophy of life of the conspicuous, female characters.O — Emmanuelle — Catherine M.

Morphology of thalamus, LGN and optic radiation do not influence EEG alpha waves
No full textRésumé : Au repos, l'activité du cerveau d'un humain sain est caractérisée par de larges fluctuations dans la bande de fréquences de 8-13 Hz d'un électroencéphalogramme (EEG), connue sous le nom de bande alpha. Bien qu'il soit établi que son activité varie d'un individu à l'autre, peu d'études se sont intéressées à la façon dont elle peut être reliée aux variations morphologiques des structures du cerveau. Entre autres, on pense que le corps géniculé latéral (CGL) et ses fibres efférentes (la radiation optique) jouent un rôle clé sur l'activité alpha, bien qu'il n'est pas certain que leur forme ou leur grosseur contribuent à sa variabilité inter-individuelle. Considérant l'utilisation courante d'EEG dans la recherche fondamentale ou clinique, ce sujet est important, mais difficile à traiter vu les problèmes associés à une bonne segmentation du CGL et de la radiation optique. Pour cette raison, nous avons utilisé la résonance magnétique de diffusion (IRMd), la résonance magnétique fonctionnelle (IRMf) et l'EEG sur 20 sujets sains pour mesurer la structure et la fonction, respectivement. L'analyse de la structure a nécessité une nouvelle approche semi-automatique pour segmenter le CGL et la radiation optique, qui nous a permis de mesurer plusieurs variables, telles que le volume et la position. Ces mesures correspondent bien aux connaissances sur la morphologie de ces structures basées sur des études post-mortem, et pourtant, nous avons trouvé que leur variabilité inter-sujet n'influençait pas la puissance des ondes alpha ou leur fréquence-type (p>0.05). Ces résultats suggèrent que la variabilité alpha soit médiée par d'autres sources structurelles. Notre méthodologie pourra servir pour de futures recherches sur l'influence de l'anatomie sur la fonction en IRMf, tomographie par émission de positron (TEP), EEG, etc., ou pour améliorer les recherches cliniques sur la radiation optique.Abstract : At rest, healthy human brain activity is characterized by large electroencephalography (EEG) fluctuations in the 8-13 Hz range, commonly referred to as the alpha band. Although it is well known that EEG alpha activity varies across individuals, few studies have investigated how this may be related to underlying morphological variations in brain structure. Specifically, it is generally believed that the lateral geniculate nucleus (LGN) and its efferent fibres (optic radiation, OR) play a key role in alpha activity, yet it is unclear whether their shape or size variations contribute to its inter-subject variability. Given the widespread use of EEG alpha in basic and clinical research, addressing this is important, though difficult given the problems associated with reliably segmenting the LGN and OR. For this, we employed a multi-modal approach and combined diffusion magnetic resonance imaging (dMRI), functional magnetic resonance imaging (fMRI) and EEG in 20 healthy subjects to measure structure and function, respectively. For the former, we developed a new, semi-automated approach for segmenting the OR and LGN, from which we extracted several structural metrics such as volume, position and diffusivity. Although these measures corresponded well with known morphology based on previous post-mortem studies, we nonetheless found that their inter-subject variability was not significantly correlated to alpha power or peak frequency (p > 0.05). Our results therefore suggest that alpha variability may be mediated by an alternative structural source and our proposed methodology may in general help in better understanding the influence of anatomy on function

Heterogeneous firms and trade costs: a reading of French access to European agro-food market
No full textThis article offers a new reading of intra-European trade based on recent developments in new international economics (Melitz, 2003; Chaney, 2008). These models take the heterogeneity of firms into account and offer a micro-economic analysis of the process of selection at work for firms entering markets. An exporting firm has to bear certain specific costs to break into a market, and only sufficiently productive firms are able to do so. Using individual data for French agro-food firms and the distribution of their exports across European markets, this article shows that access conditions to the various European markets are not identical for French firms: the Belgian market would seem to be a natural extension of the French market, whereas the markets of small, distant countries (Austria, Finland or Sweden) are the least accessible. Econometric analysis based on analysis both of the firm selection process and of the value of their exports shows that the standard geographical variables (distance, country size) affecting the single European market still play a major role in the choice of export markets. Results also reveal that there are still remaining trade costs at entry to the different European markets; but these trade frictions don’t matter to all firms in the same way. The higher the firm experience, the lower the impact of trade costs.firm heterogeneity, trade costs, European Integration., International Relations/Trade,
