    ‘He didn’t even know there was a dictatorship’: the complicity of a psychoanalyst with the Brazilian military regime

    Get PDF
    The history of psychoanalysis in Brazil during the civilian-military dictatorship (1964-1985) has come under increasing scrutiny in recent years as an instance of institutional complicity with authoritarian rule. The case of Amilcar Lobo in Rio de Janeiro is now well known. However, there is less documentation of events in São Paulo, leading to a misrepresentation of the Brazilian Psychoanalytical Society of São Paulo as having passed relatively unscathed through the dictatorial period. This paper confronts this misrepresentation by documenting the case of a psychoanalyst from São Paulo who was involved with the torture regime. A detailed account is presented of claims made to the authors about the actions of this psychoanalyst in relation to a political prisoner of the period, and some parallels are made with material in two published works by him. It is suggested that this particular psychoanalyst’s behaviour reflects attitudes prevalent in the Brazilian Psychoanalytical Society of São Paulo at the time, including its support for the view that political resistance was a sign of psychological ‘immaturity’ or pathology

    Intraoperative Indocyanine Green Laser Angiography in Pediatric Autologous Ear Reconstruction.

    Skin flap vascularity is a critical determinant of aesthetic results in autologous ear reconstruction. In this study, we investigate the use of intraoperative laser-assisted indocyanine green angiography (ICGA) as an adjunctive measure of skin flap vascularity in pediatric autologous ear reconstruction. Twenty-one consecutive pediatric patients undergoing first-stage autologous total ear reconstruction were retrospectively evaluated. The first 10 patients were treated traditionally (non-ICGA), and the latter 11 patients were evaluated with ICGA intraoperatively after implantation of the cartilage construct and administration of suction. Relative and absolute perfusion units in the form of contour maps were generated. Statistical analyses were performed using independent sample Student t test. Statistically significant differences in exposure and infection were not found between the 2 groups. However, decreased numbers of surgical revisions were required in cases with ICGA versus without ICGA (P = 0.03), suggesting that greater certainty in skin flap perfusion correlated with a reduction in revision surgeries. In cases of exposure, we found an average lowest absolute perfusion unit of 14.3, whereas cases without exposure had an average of 26.1 (P = 0.02), thereby defining objective parameters for utilizing ICGA data in tailoring surgical decision making for this special population of patients. Defined quantitative parameters for utilizing ICGA in evaluating skin flap vascularity may be a useful adjunctive technique in pediatric autologous ear reconstruction

    Non-Gaussianity in the Weak Lensing Correlation Function Likelihood -- Implications for Cosmological Parameter Biases

    We study the significance of non-Gaussianity in the likelihood of weak lensing shear two-point correlation functions, detecting significantly non-zero skewness and kurtosis in one-dimensional marginal distributions of shear two-point correlation functions in simulated weak lensing data. We examine the implications in the context of future surveys, in particular LSST, with derivations of how the non-Gaussianity scales with survey area. We show that there is no significant bias in one-dimensional posteriors of Ωm\Omega_{\rm m} and σ8\sigma_{\rm 8} due to the non-Gaussian likelihood distributions of shear correlations functions using the mock data (100100 deg2^{2}). We also present a systematic approach to constructing approximate multivariate likelihoods with one-dimensional parametric functions by assuming independence or more flexible non-parametric multivariate methods after decorrelating the data points using principal component analysis (PCA). While the use of PCA does not modify the non-Gaussianity of the multivariate likelihood, we find empirically that the one-dimensional marginal sampling distributions of the PCA components exhibit less skewness and kurtosis than the original shear correlation functions.Modeling the likelihood with marginal parametric functions based on the assumption of independence between PCA components thus gives a lower limit for the biases. We further demonstrate that the difference in cosmological parameter constraints between the multivariate Gaussian likelihood model and more complex non-Gaussian likelihood models would be even smaller for an LSST-like survey. In addition, the PCA approach automatically serves as a data compression method, enabling the retention of the majority of the cosmological information while reducing the dimensionality of the data vector by a factor of \sim5.Comment: 16 pages, 10 figures, published MNRA
