Durante el siglo XIX diversos artistas europeos emprendieron el viaje hacia diferentes puntos del continente americano. Entre ellos, mucho se dedicaron a la litografía, logrando en ciertos casos un amplio éxito comercial. Este artículo examina la trayectoria de la artista ginebrina Andrienne Pauline Macaire (1796-1855), dueña junto a su esposo de un temprano emprendimiento litográfico en la ciudad de Buenos Aires. Macaire puede ser considerada la primera artista profesional de renombre activa en esa ciudad. En efecto, es posible diferenciar su trayectoria de las de otras artistas contemporáneas, de las cuales se dispone de menos información y de las que han sobrevivido menos obras. En una primera parte del texto se analiza su inscripción en la literatura artística nacional. A continuación, se describe su formación en Ginebra y se estudia su importante actividad en Buenos Aires, estableciendo conexiones con el panorama artístico local. A lo largo del artículo se presentan obras y fuentes inéditas, o insuficientemente exploradas, a fin de justipreciar su carrera artística y de brindar elementos para futuras investigaciones.

The transition in Central and Eastern Europe since the late 1980s has provided a testing ground for classic propositions. This project looked at the impact of privatisation on private consumption, using the Czech experiment of voucher privatisation to test the permanent income hypothesis. This form of privatisation moved state assets to individuals and represented an unexpected windfall gain for participants in the scheme. Whether the windfall was consumed or saved offers a clear test of the permanent income hypothesis. Of a total population of 10 million, 6 million Czechs, i.e. virtually every household, participated in the scheme,. In a January 1996 survey, 1263 individuals were interviewed , 75% of whom had taken part. The data obtained suggests that only a small quantity of transferred assets were cashed in and spent on consumption, providing support for the permanent income hypothesis. The fraction of the windfall consumed grows with age, as would be predicted from the lower life expectancy of older consumers. The most interesting deviation was for people aged 26 to 35, who apparently consumed more that they would if the windfall were annuitised. As these people are at the stage in their lives when they would otherwise be borrowing to cover consumption related to establishing a family, etc., this is however consistent with the permanent income hypothesis, which predicts that individuals who would otherwise borrow money would use the windfall to avoid doing so.

A series of studies were undertaken to analyze and compare various aspects of murine class I glycoproteins. An initial area of investigation characterized the Qa-1 alloantigens using two-dimensional gel electrophoresis. Analysis of the products of the Qa-1('b), Qa-1('c) and Qa-1('d) alleles indicated that these were distinct molecules as determined by their lack of comigration upon comparative two-dimensional gel analysis. The importance of asparagine-linked glycosylation in the cell surface expression of class I molecules was also examined. These studies employed tunicamycin, an inhibitor of N-linked glycosylation. Tunicamycin treatment of activated T lymphocytes diminished the surface expression of Qa-1 to undetectable levels; the levels of other class I molecules exhibited little or no decrease. These results indicated that N-linked glycosylation has a differential importance in the cell surface expression of various class I molecules. The molecular weight diversity of class I molecules was also investigated. Molecular weight determination of both the fully glycosylated and unglycosylated forms of H-2 and Qa/Tla region encoded molecules established that there is a significant variation in the sizes of these forms of various class I molecules. The most significant difference ((TURN)9,000 daltons) exists between the unglycosylated forms of H-2K('b) and Qa-2, suggesting that the structural organization of these two molecules may be very different. A comparative two-dimensional gel analysis of various class I glycoproteins isolated from resting and activated T and B lymphocytes indicated that class I molecules expressed on activated T cells exhibited an isoelectrophoretic pattern that was distinct from the isoelectrophoretic pattern of class I molecules expessed on the other cell populations. This difference was attributed to a lower sialic acid content of the molecules expressed on activated T cells. Analysis of cell homogenates determined that activated T cells contained a higher level of endogenous neuraminidase activity than was detected in the other populations, suggesting that this may be the basis of the lower sialic acid content. The relationship of the Qa-4 and Qa-2 alloantigens was also examined. It was established that upon mitogen activation, the expression of Qa-4 was greatly decreased, whereas Qa-2 expression was not decreased. However, an anti-Qa-2 monoclonal antibody blocked the binding of an anti-Qa-4 monoclonal antibody to resting cells. These studies established that Qa-4 is a determinant restricted to resting cells, which is closely associated on the surface with the Qa-2 molecule. ^

By highlighting informational threats and giving them a military dimension, the authors of the Russian Federation's military doctrine have outlined the concept of information warfare. It is a kind of combat conducted by both conventional and indirect methods, open and concealed, using military and civilian structures. It has two dimensions: broader ("non-nuclear containment", i.e. combat waged on various levels - political, economic, diplomatic, humanitarian, military) and narrower (as an element supporting of action). An analysis of these issues enables us to identify several rising trends over the period 2000-2014 in Russian security policy. These boil down to a blurring of the boundaries between internal and external threats, introducing non-military methods and organisational structures to armed combat, and conferring an ideological character on this combat. This leads to a blurring of the contours of inter-state conflicts, which allows Russia to take part in armed conflicts in which it is not officially a party.
