Forms of participatory democracy: an analytical framework based on the experiences of Bolivia, brazil and Colombia

Based on the experiences of Colombia, Brazil and Bolivia, the paper proposes a general analytical framework for participatory mechanisms. The analysis is oriented to detect the incentives in each system and theethics and behavior sustaining them. It investigates about the sustainability of participatory democracy, in the face of tensions with representative democracy. The article presents a theoretical framework built from theseexperiences of institutional design and political practice, and confronts it against the theoretical conceptualizationsof participatory democracy in Bobbio, Sartori, Elster and Nino, among others. In this context, different waysin which those schemes can be inserted in the political systems become apparent, along with the variables thatresult from combining elements of direct, representative and participatory democracy”

Miocene stable isotope record of benthic foraminifera from IODP Site 320-U1336

Stable carbon and oxygen isotopes (d13C and d18O) of foraminiferal tests are amongst the most important tools in paleoceanography but the extent to which recrystallization can alter the isotopic composition of the tests is not well known. Here, we compare three middle Miocene (16-13 Ma) benthic foraminiferal stable isotope records from eastern equatorial Pacific sites with different diagenetic histories to investigate the effect of recrystallization. To test an extreme case, we analyzed stable isotope compositions of benthic foraminifera from Integrated Ocean Drilling Program Site U1336, for which the geochemistry of bulk carbonates and associated pore waters indicate continued diagenetic alteration in sediments > 14.7 Ma. Despite this diagenetic overprinting, the amplitudes and absolute values of the analyzed U1336 stable isotopes agree well with high resolution records from better preserved Sites U1337 and U1338 nearby. Our results suggest that although benthic foraminiferal tests of all three sites show some degree of textural changes due to recrystallization, they have retained their original stable isotope signatures. The good agreement of the benthic foraminiferal stable isotope records demonstrates that recrystallization occurred extremely rapidly (<100 kyr) after deposition. This is confirmed by the preservation of orbital cyclicities in U1336 stable isotope data and d18O values being different to inorganic calcite that would precipitate from U1336 pore waters during late recrystallization. The close similarity of the benthic foraminiferal stable isotope records between the sites allows the well resolved paleo-magnetic results of Site U1336 to be transferred to Sites U1337 and U1338 improving the global Geological Timescale.

Tshr Intronic Polymorphisms (rs179247 And Rs12885526) And Their Role In The Susceptibility Of The Brazilian Population To Graves' Disease And Graves' Ophthalmopathy.

Intronic thyroid-stimulating hormone receptor polymorphisms have been associated with the risk for both Graves' disease and Graves' ophthalmopathy, but results have been inconsistent among different populations. We aimed to investigate the influence of thyroid-stimulating hormone receptor intronic polymorphisms in a large well-characterized population of GD patients. We studied 279 Graves' disease patients (231 females and 48 males, 39.80 ± 11.69 years old), including 144 with Graves' ophthalmopathy, matched to 296 healthy control individuals. Thyroid-stimulating hormone receptor genotypes of rs179247 and rs12885526 were determined by Real Time PCR TaqMan(®) SNP Genotyping. A multivariate analysis showed that the inheritance of the thyroid-stimulating hormone receptor AA genotype for rs179247 increased the risk for Graves' disease (OR = 2.821; 95 % CI 1.595-4.990; p = 0.0004), whereas the thyroid-stimulating hormone receptor GG genotype for rs12885526 increased the risk for Graves' ophthalmopathy (OR = 2.940; 95 % CI 1.320-6.548; p = 0.0083). Individuals with Graves' ophthalmopathy also presented lower mean thyrotropin receptor antibodies levels (96.3 ± 143.9 U/L) than individuals without Graves' ophthalmopathy (98.3 ± 201.9 U/L). We did not find any association between the investigated polymorphisms and patients clinical features or outcome. We demonstrate that thyroid-stimulating hormone receptor intronic polymorphisms are associated with the susceptibility to Graves' disease and Graves' ophthalmopathy in the Brazilian population, but do not appear to influence the disease course.

[demographic And Clinical Features Of Patients With Rheumatoid Arthritis In Piauí, Brazil--evaluation Of 98 Patients].

Brazilian epidemiological studies on rheumatoid arthritis are scarce, mainly in the northeast; thus many data currently available originate from the international literature. To describe demographic, clinical and serological characteristics of patients with rheumatoid arthritis (RA) followed-up by the same physician, in state of Piauí, Brazil. Data were collected between August 2010 and March 2013, in three health services of Piauí that provided health care in Rheumatology: a university-affiliated hospital, a public outpatient clinic and a private clinic. The numbers represent mean ± SD or percentage: 47.5±11.03 years-old non-Caucasian woman, non-smoker (59.2%), low educational level, mean disease duration of 7.7 years ± 7.6, and major extra-articular manifestations were rheumatoid nodules (19.4%) and sicca syndrome (46.9%). Features of rheumatoid arthritis obtained in this study are similar to those found in some national and international studies, but we observed higher female preponderance and illiteracy rate, in addition to a moderately severe erosive disease on average, with frequent sicca and other extra-articular manifestations.

Membranas biológicas homólogas preservadas em solução alcalina seguida de liofilização, glicerina a 98% e por liofilização para implantação em eqüinos

Objetivou-se, neste trabalho, avaliar as alterações físico-químicas proporcionadas pelo tratamento de centros tendinosos diafragmáticos homólogos em solução alcalina seguida de liofilização, para implantação na fáscia interna do músculo reto do abdome de eqüinos. As amostras foram tratadas em períodos de 24, 48, 72, 120 e 144 horas, liofilizadas e analisadas quanto à homogeneidade, flexibilidade e resistência à sutura das amostras. Posteriormente foram caracterizadas por calorimetria exploratória diferencial e microscopia eletrônica de varredura. Para a implantação nos eqüinos, foram utilizadas amostras tratadas por 72 horas seguidas de liofilização, amostras conservadas em glicerina 98% e amostras apenas liofilizadas, que foram retiradas após uma, nove e 18 semanas para avaliar a existência de aderências. Verificou-se que a homogeneidade e a flexibilidade são diretamente proporcionais ao aumento do tempo de tratamento em solução alcalina, enquanto que a resistência é inversamente proporcional ao aumento de tempo, sendo o tratamento por 72 horas intermediário para estas características. A calorimetria exploratória diferencial mostrou que o tratamento não desnatura o colágeno presente nas amostras. Na microscopia eletrônica de varredura, observou-se que o aumento de tempo de tratamento proporciona expansão de zonas menos densas do material. Em relação à formação de aderências, as amostras apenas liofilizadas apresentaram grau máximo na formação da classificação proposta, seguida pelas amostras conservadas em glicerina 98% com grau médio e as amostras tratadas em solução alcalina e liofilizadas, que foram classificadas em grau mínimo. Concluiu-se que o tratamento por 72 horas seria mais apropriado para implantação e que a integração tissular com a parede abdominal foi melhor em relação às amostras apenas liofilizadas e às conservadas em glicerina.

High accuracy and fast acquisition time of polarisation nulling-based OSNR monitor

A technique for improving the performance of an OSNR monitor based on a polarisation nulling method with the downhill simplex algorithm is demonstrated. Establishing a compromise between accuracy and acquisition time, the monitor has been calibrated to 0.72 dB/390 ms and 0.98 dB/320 ms, over a range of nearly 21 dB. As far as is known, these are the best values achieved with such an OSNR monitoring method.
