Viajar é preciso: Theodor Koch-Grünberg e a Völkerkunde alemã do século XIX

Tomando a etnografia de Theodor Koch-Grünberg como realização ideal do projeto científico da Völkerkunde (antropologia) alemã desde a sua invenção por Waitz e, principalmente, Adolf Bastian, até a sua auto-eliminação nos primórdios do Terceiro Reich, analisamos inicialmente as raízes desse projeto na filosofia alemã, desde Herder até a ruptura neokantiana entre as ciências naturais e sociais (ou culturais) na metade do século XIX. Em seguida mostramos que, transformados em programa etnográfico, os pressupostos epistêmicos da Völkerkunde eram, desde o início, condenados ao fracasso, não obstante os heróicos esforços como este de Koch-Grünberg.

Sismogramas do choque: considerações sobre o choque em "Teoria da vanguarda", de Peter Bürger, e em "Filosofia da nova música", de Theodor W. Adorno

Em "Teoria da vanguarda", de Peter Bürger, o choque é compreendido como o artifício intencional dos movimentos de vanguarda contra a autonomia do esteticismo modernista, a fim de devolver a arte à práxis vital. Adotando uma perspectiva distinta, o choque, para Adorno, expõe antes a crise da experiência da formalização do tempo decorrente da incongruência entre as forças produtivas e as relações de produção na sociedade industrial, sendo que dois caminhos artísticos distintos derivam da inflexão histórica da crise da experiência. Em Schoenberg, na esteira do que Bürger classificaria como esteticismo, o choque seria amortizado pela expansão da linguagem musical, mediante seu registro. Em Stravinsky, o procedimento mecânico de golpes rítmicos e de montagem, em consonância com a profusão de vivências do choque, surge como elemento regressivo. Os choques não seriam dispositivos críticos, mas sismogramas de reações às mudanças da consciência subjetiva do tempo na modernidade. O artigo procura enfatizar as premissas conflitantes entre Bürger e Adorno quanto à posição do conceito de choque, assim como as críticas de Bürger ao modernismo adorniano.

Karl Popper versus Theodor Adorno: lições de um confronto histórico

Karl Popper versus Theodor Adorno: Lessons from a historical confrontation. In 1961, during the Congress of the German Society of Sociology, two great theoretical references of the XX century faced in a historical debate about the logic of the social sciences. In addition to methodological issues strict sense, the confrontation became known as a debate between positivism and dialectic. The article first deals with the theoretical trajectories of Popper and Adorno and the relation of their theories with their political and ideological certainties. On one hand, the trajectory of the Popperian epistemology is examined, its contributions and vigorous attacks on Marx in what he called 'poverty of historicism" and false predictive Marxist world, and, on the other hand, the role of Adorno in the Frankfurt School, his criticism of totalitarianism and the defense of a critical emancipatory reason. The article also deals with the confrontation itself, the exposure of Popper's twenty-seven theses that culminate with the situation logic and the method of the economy as exemplary for the social sciences and Adorno's critical perspective of sociology and society as non-separable objects. In conclusion we show how the articulation of theory with the weltanschauung of each author helps to clarify the terms of the debate and how the confrontation contributed unequivocally to the dynamics of scientific progress and for the critical history of the ideas.

Notas sobre a "carência de fundamentação" na filosofia de Theodor W. Adorno

Habermas relê Adorno e Horkheimer à luz do seu próprio modelo, isto é, do "paradigma lingüístico" que substitui a práxis transformadora pela argumentação. Assim, Habermas não percebe que, em Adorno, a competência comunicativa subordina-se a algo essencialmente diferente, a um impulso emancipatório. As características deste a priori transcendental racionalmente mediado devem ser buscadas não na Dialética do esclarecimento, mas em Minima moralia.

Theodor Adorno: filosofia de conteúdos e modelos críticos

Procura-se destacar aqui, a partir da relação de mútua dependência entre o concreto e o especulativo em Theodor Adorno, algumas características próprias de sua exposição filosófica. A recusa de definições, a busca de constelações, a construção de "modelos críticos" tornam-se mais inteligíveis quando examinadas à luz da relação entre os conceitos e o não-conceitual. Pretende-se assim esclarecer melhor a relação entre verdade e história no pensamento de Adorno.

A atualidade da discussão sobre a indústria cultural em Theodor W. Adorno

Este ensaio vem problematizar acerca da atualidade do conceito de indústria cultural (Kulturindustrie), no projeto da teoria crítica de Theodor W. Adorno, objetivando mostrar que as atuais limitações impostas ao debate derivam mais do fundamento não-dialético dos que apontam sua restrição do que da própria potência da teorização frankfurtiana.

Para uma Dialéctica Constelar: Theodor W. Adorno à entrada do Século XXI1

RESUMO: Interrogando-se sobre o lugar da filosofia de Theodor W. Adorno no âmbito do pensamento crítico contemporâneo, o presente artigo procura dar conta dos revezes da recepção político-filosófica da dialéctica negativa (das posturas críticas de Habermas, Lyotard ou Agamben às mais favoráveis de Jameson e Holloway) e discutir a sua relevância actual. Defender-se-á que a politização do pensamento adorniano é possível, muito embora as suas valências críticas não se restrinjam a essa possibilidade. Hoje, a dialéctica negativa funcionaria também como antídoto contra os atalhos tomados pelas correntes "voluntarista" (Peter Hallward), "messiânica" (Agamben) e "ontológica" (realismo especulativo) da filosofia, à entrada do século XXI. Contudo, atendendo a que a relação entre teoria e prática é complexa em Adorno, a sua relevância actual ressaltaria em relação com as reacções críticas que o movimento do "realismo especulativo" tem suscitado. Em diálogo com alguns dos seus interlocutores (Markus Gabriel e Adrian Johnston), sugere-se que o desenvolvimento de uma "dialéctica constelar" depende da introdução de um elemento destotalizador no seio do diagnóstico radical - a um só tempo materialista e transcendental - da dialéctica negativa.

A construção do espaço étnico roraimense, ou: os Taurepáng existem mesmo?

Tomando a publicação - em 1989 e 1990 - de dois folhetos "histórico-antropológicos" como um esforço por parte da Diocese de Roraima com a finalidade tipicamente "orientalista" de impor um "consenso" à sociedade roraimense quanto à "realidade étnica" do estado, nosso trabalho reconstrói a história de construção deste "consenso", desde o século XVII até os trabalhos etnográficos decisivos de Theodor Koch-Grünberg.

A epidemiologia dos "edifícios doentes"

O meio ambiente interno dos edifícios modernos, especialmente aqueles designados para uso comercial e administrativo, constitui nicho ecológico com seu próprio meio bioquímico, fauna e flora. Sofisticados métodos de construção e os novos materiais e equipamentos necessários para manter o meio ambiente interno destas estruturas fechadas produzem grande número de sub-produtos químicos e permitem o desenvolvimento de diversos microorganismos. Estes edifícios, por serem hermeticamente fechados, apresentam um dilema quanto a regulagem da umidade e temperatura do ar que circula pelos duetos, uma vez que diferentes espécies de microoganismos se desenvolvem em diferentes combinações de umidade e temperatura. Se o meio ambiente interno dos edifícios fechados não for mantido de forma adequada, pode se tornar nocivo para a saúde dos seus ocupantes. Nessas condições, edifícios fechados, são chamados de "Edifícios Doentes". Apresenta-se uma revisão da epidemiologia das doenças ocasionadas por esses edifícios fechados, etiologia das doenças dos ocupantes, origens das substâncias tóxicas e métodos possíveis para manter um ambiente interno seguro.

Alterações cutâneas do cão no Kala-Azar sul-americano

According to E. Chagas (1938), South-American Kala Azar is a widespread disease from the jungle, several cases being reported from North Brazil (Estado do Pará: Marajó Island, Tocantins and Gurupi river valleys; Estados do Piauí and Ceará: coast and hinterland). Other cases were found in Northeast Brazil (Estados de Pernambuco, Alagôas and Sergipe: coast and hinterland; Estado da Bahia: hinterland). A few cases were described from Estado de Mato-Grosso (Brazil), Provincia de Salta and Território do Chaco (Argentine), and Zona contestada do Chaco (Paraguai-Bolívia). A well defined secondary anemia associated with enlargement of the liver and spleen are the chief symptoms. Death usually occurs in cachexia and with symptoms of heart failure. Half the patients were children aged less than ten years (CHAGAS, CASTRO & FERREIRA, 1937). Quite exhaustive epidemiological researches performed by CHAGAS, FERREIRA, DEANE, DEANE & GUIMARÃES (1938) in Municipio de Abaeté (Estado do Pará, Brazil) gave the incidence of 1.48% for the natural infection in human, 4.49% in dogs, and 2.63% in cats. The infection was arcribed (CUNHA & CHAGAS, 1937) to a new species of Leishmania (L. chagasi). Latter CUNHA (1938) state, that it is identical to L. infantum. ADLER (1940) found that so far it has been impossible to distinguish L. chagasi from L. infantum by any laboratory test but a final judgment must be reserved until further experiments with different species of sandflies have been carried out. Skin changes in canine Kala Azar were signaled by many workers, and their importance as regards the transmission of the disease is recognized by some of them (ADLER & THEODOR, 1931, 2. CUNHA, 1933). Cutaneous ulcers in naturally infected dogs are referred by CRITIEN (1911) in Malta, by CHODUKIN & SCHEVTSCHENKO (1928) in Taschkent, by DONATIEN & LESTOCQUARD (1929) and by LESTOCQUARD & PARROT (1929) in Algeria, and by BLANC & CAMINOPETROS (1931) in Greece. Depilation is signaled by YAKIMOFF & KOHL-YAKIMOFF (1911) in Tunis, by YAKIMOFF (1915) in Turkestan. Eczematous areas or a condition described as "eczema furfurace" is sometimes noted in the areas of depilation (DONATIEN & LESTOCQUARD). The skin changes noticed by ADLER & THEODOR (1932) in dogs naturally infected with Mediterranean Kala Azar can be briefly summarized as a selective infiltration of macrophages around hair follicles including the sebaceous glands and the presence of infected macrophages in normal dermis. The latter phenomenon in the complete absence of secondary infiltration of round cells and plasma cells is the most striking characteristic of canine Kala Azar and differentiates it from L. tropica. In the more advanced stages the dermis is more cellular than that of normal dogs and may even contain a few small dense areas of infiltration with macrophages and some round cells and polymorphs. The external changes, i. e., seborrhea and depilation are roughly proportional to the number of affected hair follicles. In dogs experimentally infected with South-American Kala Azar the parasites were regularly found in blocks of skin removed from the living animal every fortnight (CUNHA, 1938). The changes noticed by CUNHA, besides the presence of Leishmania, were perivascular and diffuse infiltration of the cutis with mononuclears sometimes more marked near hair follicles, as well as depilation, seborrhea and ulceration. The parasites were first discovered and very numerous in the paws. Our material was obtained from dogs experimentally infected by Dr. A. MARQUES DA CUNHA< and they were the subject of a previous paper by CUNHA (1938). In this study, however, several animals were discarded as it was found that they did develop a superimposed infection by Demodex canis. This paper deals with the changes found in 88 blocks of skin removed from five dogs, two infected with two different canine strains, and three with two distinct human strains of South-American Kala Azar. CUNHA'S valuable material affords serial observations of the cutaneous changes in Kala Azar as most of the blocks of skin were taken every fortnight. The following conclusions were drawn after a careful microscopic study. (1) Skin changes directly induced in the dog by the parasites of South-American Kala Azar may b described as an infiltration of the corium (pars papillaris and upper portion of the reticular layer) by histocytes. Parasites are scanty, at first, latter becoming very numerous in the cytoplasm of such cells. Sometimes the histocytes either embedding or not leishman bodies appear as distinct nodes of infiltration or cell aggregations (histocytic granuloma, Figs. 8 and 22) having a perivascular distribution. The capillary loops in the papillae, the vessels of the sweat glands, the subpapillary plexus, the vertical twigs connecting the superficial and deep plexuses are the ordinary seats of the histocytic Kala Azar granulomata. (2) Some of the cutaneous changes are transient, and show spontaneous tendency to heal. A gradual transformation of the histocytes either containing or not leishman bodies into fixed connective tissue cells or fibroblasts occut and accounts for the natural regression just mentioned. Figs. 3, 5, 18, 19 and 20 are good illustrations of such fibroblastic transformation of the histocytic Kala Azar granulomata. (3) Skin changes induced by the causative organism of South-American Kala Azar are neither uniform nor simultaneous. The same stage may be found in the same dog in different periods of the disease, and not the same changes take place when pieces from several regions are examined in the same moment. The fibroblastic transformation of the histocytic granulomata marking the beginning of the process of repair, e. g., was recognised in dog C, in the 196th as well as in the 213rd (Fig. 18) and 231st (Fig. 19) days after the inoculation. (4) The connective tissue of the skin in dogs experimentally infected with South-American Kala Azar is overflowed by blood cells (monocytes and lymphocytes) besides the proliferation in situ of undifferentiated mesenchymal cells. A marked increase in the number of cells specially the "ruhende Wanderzellen" (Figs. 4 and 15) is noticed even during the first weeks after inoculation (prodomal stage) when no leishman bodies are yet found in the skin. Latter a massive infiltration by amoeboid wandering cells similar to typical blood monocytes (Fig. 21) associated to a small number of lymphocytes and plasma cells (Figs. 9, 17, 21, and 24) indicates that the emigration of blood cells...

Sôbre alguns Phlebotomus e Brumptomyia da Colômbia (Diptera, Psychodidae)

The first case of Kala-azar in Colombia was discovered in Soledad, S. Vicente do Chucuri, Dept. Santander, by Gast-Galvis who viscerotomized a three year old girl deceased in December, 1943. In 1944, fifty-three Phlebotominae were collected in the chicken pen of the girl's house, two new species included. Mangabeira helped by A. Gast Galvis, Juan Antonio Montoya and E. Osorno Mesa, collected some Phlebotomus in that country. The geographical distribution of the species of Phlebotomus collected in Colombia (P. abonnenci, P. camposi, P. columbianus, P. dubitans, P. gasti, P. montoyai, P. saulensis, P. serranus, P. triramulus) and two species of Brumptomyia (B. beaupertuyi and b mesari), are included. our description of the male P. columbianus is based on some specimens found in association with females. However, doubts exist about such association of sexes. There is no correspondence between the length of the spicules and the ducts of spermathecae. Besides, the specimens were not obtained by raising. The following new species are described and compared with previously known ones: a) Phlebotomus gasti sp. n. differs from the other species by a protruding tubercle in the gubernaculum. It has also fewer setae in the tuft of the basistyle, a different length of the inferior gonapophyses, and a differently shaped clasper. b) Phlebotomus dubitans sp. n. differs from P. walkeri and P. deanei (according to personal information from O. Theodor, who examined the types, they are identical to P. williamsi and P. sericeus respectively), mainly because these species have the inferior gonapophyses larger than the basistyle and fewer setae in the basistyle. P. evandroi is separated by the shape of the claspers and by the tuft of setae of the basistyle. P. marajoensis is the closest relative to P. dubitans. There is a possibility of their being synonymous. On the other hand, they can be differentiated by the existence of three extra distal spines in P. marajoensis. There is also a difference in their palpal indexes: for marajoensis I - II - IV - III - V, and for dubitans I - IV (III - II) - V. We notice, too, that the inferior gonapophyses in P. marajoensis is a little shorter. P. marajoensis has a long seta in the basistyle (clearly shown in the original drawing), not found in the new species. c) Phlebotomus montoyai sp. n.: The closest relatives are P. noguchii, P. peruensis, P. pescei, P. quinquifer and P. rickardi. They differ from the new species by the number and length of the setae of the basistyle tuft which are more numerous and longer in the new species. The shapes of their claspers are also different. Other differences are: the basal portion of the basistyle in P. noguchii is very wide (in montoyai it is narrower); the intermediate spine of the dististyle is located on a protruding tubercle ( in the new species there is hardly a tubercle); the spicules are long, and the inferior gonapophyses is longer than the basistyle. P. quinquifer and P. rickardi have a shorter dististyle and narrower wings, with different venation. The main difference, however lies, in the M4, which ends almost at the level of the junction of M1 with M2 (in P. montoyai the M4 ends far behind). In P. peruensis and P. pescei the intermediary spine of the dististyle is closer to the distal spine than to the basal one, whereas in the new species it is situated between the two pairs. Their inferior gonapophyses is longer than the basistyle. d) Brumptomyia mesai sp. n. - Closest relatives are: B. hamatus, B. pentacanthus, B. beaupertuyi which are easily separated from the new species because the tufts of their basistyle have thin and differently shaped hairs. Also their claspers are shaped differently. B. avellari is also easily recognized on account of the twisted aspect of its clasper and because the basal tuft of the basistyle has few setae, B. brumpti tuft of setae arise directly from the basistyle; these setae are stronger than those of the new species. It has 8 blade-like setae located on the inner surface of the distal half, whereas the new species has only six setae. In B. brumpti, there are three median and two terminal spines in the dististyle; in the new species, there are two median and two terminal spines and one between them, which is closer to the two median spines. The comparison with B. galindoi is based in a specimen determined by Fairchild and deposited in the entomological collection of the "Faculdade de Higiene e Saúde Pública da Universidade de S. Paulo". The genitalia of the new species is much shorter, in galindoi the inferior gonapophyses is 0,8 mm long whereas in B. mesai it hardly reaches 0,6 mm. The shape of the clasper and the distribution of its setae are different. The sub-median lamellae, besides being longer in B. galindoi are also longer in comparison with the other parts of the genitalia. The gubernaculum of the new species is longer, thinner, and more pointed; in B. galindoi it is shorter and triangular. In the drawing published by Fairchild and Hertig 91947), the basistyle shows 8 blade-like setae on the distal half, whereas in the new species only six are found.

A rewiew of the subgenus Trichopygomyia Barretto, 1962; with description of a new species from the brazilian Amazon Basin (Diptera: Psychodidae, Phlebotominae)

The subgenus Trichopygomyia Barreto, 1962 of the phlebotomine genus Lutzomyia França, 1924 is reviewed. This subgenus corresponds to the informal species group longispina of Theodor (1965). Lutzomyia (Trichopygomya) ratcliffei n.sp. from the Brazilian Amazon Basin is described. Figures, keys, distribution maps and notes on ecology are presented for all the known forms. The better known species are most frequently encountered in armadillo burrows and, therefore, could well be vectors of Leishmania.
