Prácticas comunicativas forenses: Las relaciones intertextuales en el examen de testigos. Forensic communicative practices: intertextual relations in examination of witnesses.

Inscripto en el análisis del discurso interaccional de tradición angloamericana y optando por un abordaje metodológico etnográfico, este proyecto plantea investigar las relaciones entre textos orales y entre textos orales y escritos vinculados en cadenas textuales en un acontecimiento comunicativo institucional en el que tales relaciones tienen consecuencias directas en la confiabilidad de la información e intervienen en la construcción del conocimiento oficial. La situación comunicativa elegida es el examen y el contraexamen de testigos comunes durante procesos penales orales, de formato común no abreviado, en la jurisdicción de Córdoba capital. En las interacciones verbales con litigantes y jueces en las que emerge el testimonio se ponen en juego otros textos orales (en forma de citas de lo dicho antes por el mismo testigo u otras personas, referencias a rumores u opiniones colectivas, etc.) y textos escritos (actas de secuestro, informes periciales, actas de las declaraciones testimoniales en la etapa de instrucción, etc.). El foco de atención son las prácticas asociadas a la intertextualidad puesto que condicionan el carácter de la prueba testimonial producida ante el juzgador. Postulamos que los litigantes despliegan tácticas locales y estrategias globales reconocibles y recurrentes vinculadas al tratamiento de diversas categorías de textos previos. Además, planteamos averiguar si la participación de los jueces en interacción con los testigos es de suficiente injerencia como para ser un modo importante de generación de prueba testimonial. El enfoque metodológico general es etnográfico y analíticodiscursivo. Se seleccionará una causa por delito grave, se presenciará el debate en la cámara y se registrará el audio de todas las audiencias. Los datos a analizar serán los segmentos en las interacciones en los que se incorpora la lectura o se cita las actas de las declaraciones indagatorias o testimoniales anteriores, y los segmentos en los que se requiere, en calidad de prueba testimonial, la reproducción de dichos. Se procederá a partir de los detalles de la superficie textual y la pragmática de los intercambios y aprovechando el valor heurístico del concepto de voz, buscando identificar patrones recurrentes y los mecanismos generales que los rigen. Sobre esa base, se considerarán los intercambios verbales como interacción social que emerge moldeada por condiciones situacionales e institucionales y otros factores, tales como la incidencia de la pertenencia a grupos sociales o profesionales. Con el estudio se obtendrá una visión de prácticas cotidianas asociadas a la intertextualidad que son de crucial importancia para el carácter de la prueba testimonial producida ante el juzgador. Este paso nos acercará a conocer cómo se lleva a cabo efectivamente la administración de justicia penal y permitirá valorar los patrones de conducta a la luz de las normas procesales. In line with the Anglo-American tradition of situated discourse analysis, this project aims at tracing the links between oral texts and between oral and written texts related in textual chains which are present in an institutional event in which such relations have a direct consequence on the reliability of the information given and have an impact on the construction of what counts as official knowledge. The communicative situation under study is that of the direct and cross-examination of lay witnesses during a criminal trial in the city of Córdoba. During the face-to-face interactions between trial lawyers and judges in which the testimony takes place, other oral texts and written texts get incorporated. The focus of this research is centered on practices of intertextuality as they condition the nature of the oral evidence produced. It is argued that trial lawyers use recurrent local tactics and global strategies that are related to the treatment given to different categories of previous texts. Another aim of this study is to examine if judge’s interventions have an impact on the generation of the oral evidence. The data will come from a criminal trial that will be audio-taped in its entirety. Ethnographic observations of a criminal trial will be made. The focus of analysis will be on segments of interactions in which previous texts are read aloud or incorporated as quotes. After carrying out a detailed analysis of the surface of texts and the pragmatics of the exchanges, recurrent patterns and the general mechanisms that condition their emergence will be described. In this way, verbal exchanges will be considered social interactions that unfold conditioned by situational, institutional and social factors. This study will examine the relationship between intertextuality and the institutional practice of providing oral evidence. This will help understand how justice is actually administered and how patterns of behavior are valued according to institutional norms.

Evolution of Cardiovascular Diseases Mortality in the Counties of the State of Rio de Janeiro from 1979 to 2010

Background: Cardiovascular Diseases (CVD) are the leading cause of death in Brazil. Objective: To estimate total CVD, cerebrovascular disease (CBVD), and ischemic heart disease (IHD) mortality rates in adults in the counties of the state of Rio de Janeiro (SRJ), from 1979 to 2010. Methods: The counties of the SRJ were analysed according to their denominations stablished by the geopolitical structure of 1950, Each new county that have since been created, splitting from their original county, was grouped according to their former origin. Population Data were obtained from the Brazilian Institute of Geography and Statistics (IBGE), and data on deaths were obtained from DataSus/MS. Mean CVD, CBVD, and IHD mortality rates were estimated, compensated for deaths from ill-defined causes, and adjusted for age and sex using the direct method for three periods: 1979–1989, 1990–1999, and 2000–2010, Such results were spatially represented in maps. Tables were also constructed showing the mortality rates for each disease and year period. Results: There was a significant reduction in mortality rates across the three disease groups over the the three defined periods in all the county clusters analysed, Despite an initial mortality rate variation among the counties, it was observed a homogenization of such rates at the final period (2000–2010). The drop in CBVD mortality was greater than that in IHD mortality. Conclusion: Mortality due to CVD has steadily decreased in the SRJ in the last three decades. This reduction cannot be explained by greater access to high technology procedures or better control of cardiovascular risk factors as these facts have not occurred or happened in low proportion of cases with the exception of smoking which has decreased significantly. Therefore, it is necessary to seek explanations for this decrease, which may be related to improvements in the socioeconomic conditions of the population.

Ecological relations between mangrove leaf litter and the spatial distribution of the gastropod Melampus coffeus in a fringe mangrove forest

Leaf litter represents a food source to many organisms that may directly contribute to organic matter decomposition. In addition, the physical presence of these vegetal detritus contributes for the modification of some environmental areas and produce microhabitats that may act as a refuge against predators and desiccation for many animals. The pulmonate gastropod Melampus coffeus (Linnaeus, 1758) (Ellobiidae) is a very common specie in Atlantic Coast mangrove forests and feeds on fallen mangrove leaves. It was hypothesized that the spatial distribution of Melampus coffeus is directly affected by mangrove leaf litter biomass deposition. Thus, this research aimed at evaluating the spatial distribution of these gastropods in relation to the biomass of mangrove leaf litter through a twelve-month period. The study area was established in the middle estuary of Pacoti River, state of Ceará, Brazil where two adjacent zones with different topographic profiles were determined. Samples of Melampus coffeus and leaf litter were collected monthly, throughout a year, from the mangrove ground surface. The results indicated that the presence of twigs in mangrove litter favor the occupation by smaller individuals of M. coffeus, probably because smaller individuals are more susceptible to predator attacks and desiccation than larger ones, and twigs and branches may provide a safe microhabitat.

Dermatozoonosis by Culicoides' bite (Diptera, Ceratopogonidae) in Salvador, State of Bahia, Brazil: IV - A clinical study

A observação de 211 pacientes com reação intensa à picada do Culicoides, que procuraram tratamento na Clínica dermatológica do Hospital das Clínicas da Universidade da Bahia, durante os anos de 1959 e 1962, permitiu o estudo clínico dessa Dermatozoonose, cujos dados são aqui apresentados. A lesão parece ser de natureza alérgica e devido ao aspecto polimorfo pelo qual se apresenta, essa Dermatose pode lembrar o Prorigo, a Escabiose, as Lesões liquenoide; quando a manifestação é mais intensa torna-se uma verdadeira eczematização; quando há infecção secundária, lembra o impetigo folicular. O estudo histológico da lesão revelou ser ela a de uma inflamação crônica, com vascularites e preivascularites dermo-epidérmica, provàvelmente de natureza alérgica. Para que haja a formação da lesão, são necessários: a substância inoculada pelo inseto e o componente alérgico do indivíduo. Não se conhece a natureza da substância inoculada pelo inseto e as seguintes hipóteses são apresentadas para explicá-la: substâncias enzimáticas ou a histamina existentes nas glândulas salivares do Culicoides. Após a picada do Culicoisdes forma-se no local uma pequena área eritematosa que logo após se transforma em pápula; as pápulas podem desaparecer ou transformarem-se em vesículas; estas ao se romperem dilaceram a superfície cutânea, descamam-na ou pode advir uma infecção secundária e transformam-se em pústulas.

Serological studies on an outbreak of smallpox in the State of Bahia - Brazil in 1969

Four weeks after Containment Vaccination undertaken against the largest outbreak of smallpox occured in Brazil in 1969, that of the municipality of Utinga, Bahia, 99 samples of serum were collected from the local population. These samples were classified in four groups: a) - Individuals with a history of variola prior to the beginning of present outbreak in town (15 sera); "Previous smallpox group"; b) - Individuals with primary vaccination, with no record variola, at the time of containment measures (15 sera). "Primary vaccinated group"; c) - Individuals with no previous record of variola revaccinated with "take" at the time of containment (15 sera0, "Revaccinated group"; d) - Individuals who contracted variola in present outbreak (54 sera) these were subdivided in four sub-groups, according to dates on which cases ocurred, "Variola in outbreak group". Serological study of samples was done by tests of hemagglutination inhibition, neutralization, and complement fixation. It was observed that HI titers were significantly lower in cases of previous smallpox than in other groups. Although they were slightly higher on revaccinated individuals than on primary vaccinated group and than in the group of variola in outbreak, this difference was not significant. Those same antibodies were present in all cases of variola in outbreak, and it was found that titers decreased in direct proportion to time elapsed from occurrence of cases. Neutralizing antibodies proved to be significantly higher on the revaccinated group than on variola in outbreak group, and higher on these than on primary vaccinated and on the previous smallpox groups. In cases from the variola in outbreak it was verified that neutralizing antibodies remained stable, although with great variation in titers. Tests of complement fixation could not be undertaken on all samples, because many of them proved to have anticomplementarity. However, it was found that complement fixing antibodies diminished rapidly, becoming negative for earlier infections. Finally, the authors suggest that there would be some evidence that HI titers are lower in variola minor under Brazilian conditions than in variola major.

A pilot study to control Lutzomyia umbratilis (Diptera: Psychodidae), the major vector of Leishmania brazileiensis guyanensis, in a peri-urban rainforest of Manaus, Amazonas State, Brazil

In the second half of 1980, 112 (or ca. 16%) of the inhabitants of the new settlement of São José, city of Manaus, contracted cutaneous leishmaniasis whilst clearing their properties of terra firme rainforest. With the aid of SUCAM, the authors carried out a pilot study to investigate the feasibility of reducing populations of Lutzomyia umbratilis, the local silvatic vector of Leishmania braziliensis guyanensis, by spraying insecticide on its favoured diurnal resting sites, the bases of the larger forest trees. Most manvector contact is at these resting sites and, therefore, it was encouraging to record a marked reduction of the tree-base populations of L. umbratilis for 21 days following just one application of D.D.T. emulsion in an area 200m square. Most of the treated trunks were not occupied by L. umbratilis for at least eleven months. Suggestions for extending the pilot study are made, and the need for collaboration with a clinical team is emphasized. Leishmania b. guyanensis is the aetiological agent of [quot ]pain bois[quot ], which is hyperendemic from French Guiana to central Amazônia. In the absence of proven vaccines or methods of vector control, some simple methods for limiting transmission of Le. b. guyanensis to man are listed.

Anopheline species, some of their habits and relation to malaria in endemic areas of Rondônia State, Amazon region of Brazil

In view of recent studies incriminating several species of anophelines, besides Anopheles darlingi, as malaria vectors in the Brazilian Amazon, we performed an anopheline survey in four localities - Ariquemes, Cujubim, Machadinho and Itapoã do Oeste - in Rondônia, the most malarious State in the Country. Twenty species were found. An. darlingi was, by far, the dominant species and the only one whose density coincided with that of malaria. On human baits it was more numerous in the immediate vincinity of houses than indoors whre, however, it was almost the only species encountered. On both situations it fed mostly at sunset and during the first half of the night. It was less numerous far from houses and scarce inside the forest. Other species (An. triannulatus, An. evansae, An. albitarsis, An. strodei) appeared in appreciable numbers only in Ariquemes, both in areas with and without malaria. The remaining species were scanty. An. darlingi was confirmed as the primary local vector.

The threat of reintroduction of natural transmission of Chagas' disease in Bambuí, Minas Gerais state, Brazil, due to Panstrongylus megistus

In the Epidemiological Surveillance Program in the county of Bambuí, Minas Gerais, between August 1986 and December 1988, 154 Panstrongylus megistus were captured by the local population in both peridomicile and intradomicile environments. Fifteen (9.8%) of the P. megistus harboured Trypanosoma cruzi. Preciptin tests showed that the most frequent triatomine blood meal sources were birds, but other sources were dogs, men and cats. The isoenzyme characterization of 13 T. cruzi strains showed that six belonged to zymodeme Z1, corresponding to the wild parasites, and seven belonged to zymodeme Z2, corresponding to parasites isolated from chronic chagasic patients (domestic cycle). As P. megistus were found to be naturally infected by parasites from both cycles, they are cleary able to transmit T. cruzi from the wild cycle to the domestic cycle. Furthermore the capacity of P. megistus in colonizing houses was observed in one residence, vacant for several years, in wich 153 triatomines were captured. The data show the possibility of P. megistus reintroducing transmission of Chaga's disease in the county if Epidemiological Surveillance is interrupted.

Living in the Wrong Neighbourhood: State Failure and its Implications for Neighbouring Countries

Why and how do failed states affect neighbouring countries? The attention of the international community towards state failure has grown significantly in recent years, improving the understanding of this phenomenon; nevertheless, the knowledge about the influence of state failure on neighbouring countries remain scarce. This research aims at contributing to filling up the existing gap by analyzing two different cases of state failure –Liberia and Afghanistan– and its consequences on four of their neighbours –Sierra Leone, Guinea, Pakistan and Tajikistan. More concretely, this research investigates the importance of insurgency movements in the relationship between these countries. The research argues that failed states generate conflict-enhancing mechanisms –which might lead to conflict outbreak– in their neighbours through the creation of informal networks. The empiric evidence shows how insurgency-based informal networks have a decisive role in the outbreak of conflict.

An Investigation on the Ecology of Triatoma vitticeps (Stal, 1859) and its Possible Role in the Transmission of Trypanosoma cruzi, in the Locality of Triunfo, Santa Maria Madalena Municipal District, State of Rio de Janeiro, Brazil

From January 1989 to April 1995, 465 specimens of Triatoma vitticeps were collected in the locality of Triunfo, 2nd District of Santa Maria Madalena municipal district, State of Rio de Janeiro. The bugs were found indoors by local residents with predominance of adults. The flight activity was high in hot months when the incidence in the domicile also increased. Two hundred and two bugs (111 alive and 91 dead) were examined for Trypanosoma cruzi infection. This was detected in 31 of the dead bugs (34%) and 88 (79%) of the live bugs examined. With a view to investigate the possible vertebrate hosts of the T. cruzi isolates, the blood of 122 mammals was examined through Giemsa-stained smears, hemocultures and xenodiagnosis. T. cruzi was detected in three specimens of Didelphis marsupialis and T. (M.) theileri was detected in one specimen of Bos taurus. The parasites were isolated from triatomine feces, xenoculture and hemoculture. No evidence of human infection was detected in 58 inhabitants examined, as evaluated by indirect imunofluorescence technique using T. cruzi epimastigotes as antigens. These results show that T. vitticeps is still a sylvatic species although nymphs have been found inside the domicile. Thus, an epidemiological vigilance is necessary to know the behaviour of this species following the continuous modifications promoted by the presence of man.
