Governo das sociedades e responsabilidade social

O governo das sociedades tem vindo a ser alvo de uma atenção crescente, visível através de um conjunto de regras e de procedi-mentos cuja finalidade é otimizar o desempenho das organizações. A responsabilidade social é assumida pela adoção voluntária de preocupações e de medidas para com a Comunidade, daí que ser socialmente responsável é estar muito para além do mínimo exigido legalmente. Ao analisar a relação entre o governo das sociedades e a respon-sabilidade social, constata-se que ambos têm sido investigados de forma crítica e independente. Com este trabalho procura-se compre-ender e simultaneamente interpretar e transmitir como é que as sociedades emitentes de ações, admitidas a negociação no merca-do de cotações oficiais da NYSE Euronext Lisbon, observam essa relação à luz de três modelos empíricos. Neste âmbito, apresenta-se um estudo de caso para se apreciar o comportamento das em-presas que constituem o PSI201, à data de 31 de dezembro de 2012, para o período compreendido entre 2010 e 2012. Da análise pode-se concluir da existência de uma relação entre o governo das sociedades e a responsabilidade social.

BAT-BORNE RABIES IN LATIN AMERICA

The situation of rabies in America is complex: rabies in dogs has decreased dramatically, but bats are increasingly recognized as natural reservoirs of other rabies variants. Here, bat species known to be rabies-positive with different antigenic variants, are summarized in relation to bat conservation status across Latin America. Rabies virus is widespread in Latin American bat species, 22.5%75 of bat species have been confirmed as rabies-positive. Most bat species found rabies positive are classified by the International Union for Conservation of Nature as “Least Concern”. According to diet type, insectivorous bats had the most species known as rabies reservoirs, while in proportion hematophagous bats were the most important. Research at coarse spatial scales must strive to understand rabies ecology; basic information on distribution and population dynamics of many Latin American and Caribbean bat species is needed; and detailed information on effects of landscape change in driving bat-borne rabies outbreaks remains unassessed. Finally, integrated approaches including public health, ecology, and conservation biology are needed to understand and prevent emergent diseases in bats.

Studies on a small collection of planorbid snails from southern south America

Snails belonging to Biomphalaria genus were collected from some regions of Southern South America as follows: Resistencia, province of Chaco, Argentina; Assumpcion, Paraguay; Department of Maldonado of Caneloni, Uruguay; and Pôrto Alegre, Rio Grande do Sul, Brazil. The material was classified as Biomphalaria peregrina (Orbigny) twice from Uruguay and once in Brazil; B. tenagophila (Orbigny), from Argentina and Brazil; and B. straminea (Dunker) in Paraguay. Negative results were obtained from the exposition of the abone refered snail specimens to miracidia of S. mansoni from Pernambuco, Brazil.

Clinical and laboratorial evidence of Rickettsia felis infections in Latin America

After the discovery and initial characterization of Rickettsia felis in 1992 by Azad and cols, and the subsequent first description of a human case of infection in 1994, there have been two communications of human rickettsiosis cases caused by Rickettsia felis in Latin America. The first one was published in 2000 by Zavala-Velazquez and cols in Mexico. In 2001 Raoult and cols described the occurrence of two human cases of Rickettsia felis rickettsiosis in Brazil. In the present discussion these two articles were compared and after the description of the principal signs and symptoms, it was concluded that more studies are needed with descriptions of a greater number of patients to establish the true frequency of the clinical signs and symptoms present in Rickettsia felis rickettsiosis.

História e memória. Estudo sobre as sociedades de Lunda e Cokve de Angola

O tema “Memória, Identidade e História, estudo sobre as sociedades Lunda e Cokwe”, surgiu como resultado de um tempo de trabalho, com a obra monumental de Henrique Dias de Carvalho, viajante português que, no século XIX, empreendeu uma viagem de exploração pelo interior de Angola, destinada ao estabelecimento e assinatura de protocolos com os povos de Malanje à Lunda e que se realizou entre 1884 e 1887. Uma primeira abordagem dos textos deste viajante português dentro dos princípios da teoria do texto, em busca da sua literariedade, da qual resultou uma dissertação de mestrado, obrigou a deixar de lado um repositório de informações sobre a história de sociedades referidas. Assim procurou-se, agora, estudar as sociedades lunda e cokwe (quioca na etnografia colonial), seus desenvolvimentos internos e suas reacções ao modelo de exploração mineiro em marcha desde 1907. Uma grande parte do esforço foi mobilizado em torno da investigação dos fenómenos culturais do fazer e refazer de identidades para permitir a compreensão das diferenças sociais, políticas, económicas e outras assumidas por estes povos e sobre eles projectada, durante um período histórico que se alarga ao século XIX e se fixa com mais detalhe nas primeiras décadas do século XX., com a descoberta dos primeiros diamantes e a modificação profunda dos vários actores das sociedades em presença, facto que se apresenta consolidado na década de quarenta do século XIX. Procurou-se seguir e dar conta das diferentes manifestações que assumiram estas sociedades enquanto entidades autónomas e suas originalidades na produção do político, do económico e social. O trabalho segue as transformações do antigo Império Lunda, designação que a historiografia consagra e discute) importante para a compreensão da maioria das sociedades históricas da África Central antes e depois da colonização. Três impérios coloniais traçaram fronteiras, modos de exploração e assimilação sobre sociedades que se reclamam de uma origem mítica comum. Reconhece-se que a produção do conhecimento se faz do cruzamento de múltiplas fontes e por isso se fez recurso da história oral na busca dos traços mais importantes do passado distante e da relação que cada indivíduo estabelece com a ideia de império, fronteira, poder colonial. Socorremo-nos do suporte teórico de várias disciplinas para percorrer o caminho da história, da memória e das formulações identitárias que constituem suporte e referência para a maioria dos entrevistados.

Dirofilariasis involving the oral cavity: report of the first case from South America

Oral dirofilariasis is very rare with non-specific clinical manifestations. Here, we report the case of a 65-year-old South American woman with a submucosal nodule on her right buccal mucosa. The nodule was slightly tender and painful. Differential diagnoses included mesenchymal (lipoma or fibrolipoma, solitary fibrous tumor, and neurofibroma) or glandular benign tumors (pleomorphic adenoma) with secondary infections. We performed excisional biopsy. A histopathological examination revealed a dense fibrous capsule and a single female filarial worm showing double uterus appearance, neural plaque, well-developed musculature and intestinal apparatus. Dirofilariasis was diagnosed, and the patient was followed-up for 12 months without recurrence.

Trypanosoma cruzi isolated from a triatomine found in one of the biggest metropolitan areas of Latin America

Abstract: INTRODUCTION: To characterize Trypanosoma cruzi (TcI) isolated from a Panstrongylus megistus specimen found in one of the biggest metropolitan areas of Latin America, the relationship between the TcI group of T. cruzi and the transmission cycle in the urban environment was studied. METHODS: The T. cruzi strain, Pm, was isolated in a culture medium from the evolutionary forms present in the hindgut of a live male specimen of P. megistus found in the Jabaquara subway in São Paulo City. The sample from the triatomine showed trypomastigote forms of Trypanosomatidae, which were inoculated in the peritoneum of Balb/c mice. The sample was then inoculated in Liver Infusion Tryptose medium and J774 cells for the molecular identification and characterization of the parasite. The Pm strain of T. cruzi was identified by isolation in axenic culture medium, and based on the morphology, cell infection, growth kinetics, and molecular characterization. RESULTS: After isolation, the protozoan was identified as T. cruzi. No parasites were detected in the peripheral blood of the animal, which can be a characteristic inherent to the strain of T. cruzi that was isolated. Cell invasion assays were performed in triplicate in the J774 cell line to confirm the invasive ability of the Pm strain and revealed amastigote forms of the parasite within macrophages. CONCLUSIONS: Our biological and molecular characterizations helped understand parasite-host interactions and their evolutionary history in context of the associations between vectors, ecotopes, hosts, and groups of the parasite.

Cyperaceae of Tropical America: some new or critical species III

Discussed are the taxonomy of the Scleria arundinacea-latifoliacomplex, S. mitis, and S. myricocarpa, all controversial and widespread taxa in tropical America. Scleria cerradicola is described as new in the section Hymenolytrum and a range extension of a rare species, Scleria neogranatensis, is noted.

The Simaba guianensis complex in northers South America

With additional data from specimens not studied by previous workers, the confusing Simaba guianensis compex was re-analized. Simaba polyphylla is recognized as a distinct species and two subspecies of S. guianensis are maintained. Simaba polyphylla, S. guianensis ssp. guianensis, and S. guianensis ssp. ecaudata are keyed, described, and illustrated and specimens examined are cited for each. Specimens of S. guianensis ssp. ecaudata show great morphological diversity but can be separeted into three groups. Further collecting may provide information that shows these groups to be worthy of separate taxonomic status.

DISTRIBUTION AND FEEDING ECOLOGY OF THE AFRICAN TILAPIA Oreochromis mossambicus (TELEOSTEI, PERCIFORMES, CICHLIDAE) IN SURINAME (SOUTH AMERICA) WITH COMMENTS ON THE TILAPIA-KWIKWI (Hoplosternum littorale) (TELEOSTEI, SILURIFORMEs, CALLICHTHYIDAE) INTERACTION

The geographical distribution of the African Tilapia Oreochromis mossambicusin Suriname is restricted to a narrow strip of land along the Atlantic coast. Within the coastal plain, O. mossambicusoccurs in brackish lagoons, oligohaline canals, and shell-sand pit lakes. Physico-chemical characteristics and phytoplankton composition of representative Tilapia water bodies are described. Blue-green algae and fine flocculent detritus are dominant food items in the diet of the Tilapia, while Rotifera and microcrustacea are also important in the diet of larvae and juveniles. Intraspecific diet overlap among ontogenetic stages of the Tilapia did not differ significantly from 1, which means that these diets showed complete overlap. Interspecific diet overlap between the Tilapia and the indigenous armoured catfish Hoplosternum littoralewere moderate or low. The results are discussed in relation to recent developments in the Surinamese fisheries and aquaculture sector.

The drought of the century in the Amazon Basin: an analysis of the regional variation of rainfall in South America in 1926

The most severe drought in tropical South America during the 20th century occurred in 1926. This extreme El Nino year is further documented anecdotally, in an update of the river stage observations at Manaus, and in annual rainfall records. The annual rainfall anomaly is an east-west dipole over tropical South America, with drought to the west over the Amazon basin whose discharge is documented at Manaus, and with a surplus to the east and including the Nordeste region of Brazil. Speculations about a role for aerosol in aggravating the drought are discussed.
