From an initial double infection in mice, established by simultaneous and equivalent inocula of bloodstream forms of strains Y and F of Trypanosoma cruzi, two lines were derived by subinoculations: one (W) passaged every week, the other (M) every month. Through biological and biochemical methods only the Y strain was identified at the end of the 10th and 16th passages of line W and only the F strain at the 2nd and 4th passages of line M. The results illustrate strain selection through laboratory manipulation of initially mixed populations of T. cruzi.

We report preliminary findings from analysis of a database under construction. The paper explores the legislative process in search for some of the alleged consequences of cabinet coalitions in a presidential system. Coalition effects should be less evident in the success of executive initiatives: strategic behavior hampers this intuitive measure of performance. Better measures, because less subject to strategic considerations, are the odds of passage of legislators' bills and the time proposals take to be approved. Thus measured, coalition effects are discernible. Analysis of the universe of proposals processed in the fragmented Uruguayan Parliament between 1985 and 2000 reveals that coalition, observed about half the period, swells success rates of coalition members by 60% on average (and by as much as 150% for those close to the president). Event history analysis shows that coalitions cut the wait for an executive bill by 3 months, 1/6th the average wait. The reverse effect is felt on the duration of legislators' bills.

Une représentation sociale communément admise postule que le couple plurilingue et l'un de ses prolongements possibles, la vie en commun dans un pays, favorisent l'appropriation de la langue et la socialisation du partenaire alloglotte. Or, si c'est souvent le cas, il s'agit de dégager les conditions nécessaires à un tel processus positif d'apprentissage de la langue. De là découle l'intérêt d'une observation ethnographique des caractéristiques d'un mode d'apprentissage de la langue du milieu (ici, le français) qui s'actualise dans les couples plurilingues. Dans cet article je montrerai, par l'exemple d'un couple francophone/hispanophone établi en Suisse romande, comment la situation matrimoniale hétéroglotte propose un contexte spécifique à l'apprentissage de la langue. Je porterai particulièrement mon attention sur la construction par le partenaire alloglotte d'un sentiment de légitimité quant à son statut de locuteur plurilingue francophone
