This article focuses on the circulation of educational models between Portugal and Brazil (from 1920 to 1935), within a broader context of an intensive international transfer of "ways of thinking" about education. It describes and analyses the results from research on two educational journals, one Portuguese (Revista Escolar) the other from the Brazilian State of Sao Paulo (Education). Central to this text is the notion that educational journals constitute important vehicles for the production and regulation of knowledge as well as for the formation of specialized fields in education. Thus, the article gives particular attention to the selective mobilization of foreign educational models (countries, authors and educational organizations), within a framework of analysis committed to the articulation of the processes of diffusion and reception of educational knowledge. The article presents the characteristics of both journals, in the face of those (geo-political and intellectual) international references, and compares the relations of affiliation and affinity with foreign models displayed by each journal. The analysis shows: (i) the centrality of authors and organizations associated with the New Education in the promotion of knowledge that proposes to mediate scientific production and pedagogical practice; (ii) the existence of differences regarding the foreign countries that are taken as models for education improvement at a national scale; (iii) the presence of different spaces for the (worldwide) circulation of pedagogical models (the New Education circuit and the Latin-American circuit); (iv) the scarce referencing of the other "who speaks the same language." Results are discussed by taking into consideration their relationships with the structuration of pedagogical discourses and organisations, in both national and international spheres.

HIV-1 clade C isolates show reduced Tat protein chemoattractant activity compared with clade B. This might influence neuropathogenesis by altering trafficking of monocytes into the CNS. A previous study suggested low rates of HIV-associated dementia in clade C-infected individuals. The present study evaluated neurocognitive impairment rates in clade B- and C-infected individuals from the same local population. HIV+ and HIV- participants were recruited from the same geographic region in Southern Brazil. We evaluated neuropsychological (NP) impairment using a screening instrument (the International HIV Dementia Scale (IHDS)), as well as a Brazilian Portuguese adaptation of a comprehensive battery that has demonstrated sensitivity to HIV-associated neurocognitive disorders (HAND) internationally. NP performance in controls was used to generate T scores and impairment ratings by the global deficit score (GDS) method. Clade assignments were ascertained by sequencing pol and env. Blood and cerebrospinal fluid were collected from all HIV+ participants. HIV+ and HIV- participants were comparable on demographic characteristics. HIV+ participants overall were more likely to be impaired than HIV- by the IHDS and the GDS. Clade B- and C-infected individuals were demographically similar and did not differ significantly in rates of impairment. The prevalence of pleocytosis, a marker of intrathecal cellular chemotaxis, also did not differ between clade B and C infections. Clade B and C HIV-infected individuals from the same geographic region, when ascertained using comparable methods, did not differ in their rates of neurocognitive impairment, and there was no evidence of differences in CNS chemotaxis.
