Historical Roots of Histrionic Personality Disorder

Histrionic Personality Disorder is one of the most ambiguous diagnostic categories in psychiatry. Hysteria is a classical term that includes a wide variety of psychopathological states. Ancient Egyptians and Greeks blamed a displaced womb, for many women's afflictions. Several researchers from the 18th and 19th centuries studied this theme, namely, Charcot who defined hysteria as a "neurosis" with an organic basis and Sigmund Freud who redefined "neurosis" as a re-experience of past psychological trauma. Histrionic personality disorder (HPD) made its first official appearance in the Diagnostic and Statistical Manual of Mental Disorders II (DSM-II) and since the DSM-III, HPD is the only disorder that kept the term derived from the old concept of hysteria. The subject of hysteria has reflected positions about health, religion and relationships between the sexes in the last 4000 years, and the discussion is likely to continue

Portfolio choice with high frequency data : CRRA preferences and the liquidity effect

This paper suggests a new approach for portfolio choice. In this frame- work, the investor, with CRRA preferences, has two objectives: the maximization of the expected utility and the minimization of the portfolio expected illiquidity. The CRRA utility is measured using the portfolio realized volatility, realized skewness and realized kurtosis, while the portfolio illiquidity is measured using the well-known Amihud illiquidity ratio. Therefore, the investor is able to make her choices directly in the expected utility/liquidity (EU/L) bi-dimensional space. We conduct an empiri- cal analysis in a set of fourteen stocks of the CAC 40 stock market index, using high frequency data for the time span from January 1999 to December 2005 (seven years). The robustness of the proposed model is checked according to the out-of-sample per- formance of different EU/L portfolios relative to the minimum variance and equally weighted portfolios. For different risk aversion levels, the EU/L portfolios are quite competitive and in several cases consistently outperform those benchmarks, in terms of utility, liquidity and certainty equivalent.info:eu-repo/semantics/publishedVersio

CVD of CrO2 Thin Films: Influence of the Deposition Parameters on their Structural and Magnetic Properties

This work reports on the synthesis of CrO2 thin films by atmospheric pressure CVD using chromium trioxide (CrO3) and oxygen. Highly oriented (100) CrO2 films containing highly oriented (0001) Cr2O3 were grown onto Al2O3(0001) substrates. Films display a sharp magnetic transition at 375 K and a saturation magnetization of 1.92 Bohr magnetons per f.u., close to the bulk value of 2 Bohr magnetons per f.u. for the CrO2. Keywords: Chromium dioxide (CrO2), Atmospheric pressure CVD, Spintronics.Comment: 5 pages, 6 figure

Reassessment of exclusion zones of GM cotton in Brazil: the case of Rondônia State.

Cotton (Gossypium hirsutum) was the second crop to received commercial approval to planting GM cultivars in Brazil, in 2005. At that time, the main concern was the possibility of gene flow from GM cottons to affect in situ maintenance of others species sexually compatible ? G. barbadense and G. mustelinum. To avoid this problem, the National Biosafety Technical Commision (CTNBio) conditioned the cultivation of GM cotton to the creation of GM Cotton Exclusion Zones, where just non-GM cultivars could be planted. Cotton cultivation is an important agricultural activity in Brazil and the producers are almost unanimous: fields of GM cultivars yield more, the management is less laborious and the protection against weeds and pests is higher. For these reasons, farmers in the Rondonia, a state included into the exclusion zones, requested CTNBio to remove Rondônia from the exclusion zones. To deliberate, CTNBio asked Embrapa for information. To properly answer, an expedition was performed in 20 of the state?s 52 municipalities, and only one species was found, Gossypium barbadense. Plants were present just in higly anthropized areas, mainly in dooryards of urban and rural houses, and they were maintained as medicinal plants. Plants of G. barbadense were found in 5% to 10% of the houses, protected from gene flow by walls, houses, and trees. There was no signal of interespecifc crossing, even in municipalities were conventional Gossypium hirsutum were planted. The main risk to in situ mainatenance of G. barbadense is the loss of cultural habits resulting from the expansion of the public health care, which increases the use of chemical drugs over medicinal plants. In conclusion, gene flow is not a significant concern to the preservation of Gossypium barbadense in Rondônia, and there is no reason for the state to remain as an exclusion zones

A Hybrid Analytical-Numerical Model Based on the Method of Fundamental Solutions for the Analysis of Sound Scattering by Buried Shell Structures

Several numerical and analytical models have been used to study underwater acoustics problems. The most accurate and realistic models are usually based on the solution of the wave equation using a variety of methods. Here, a hybrid numerical-analytical model is proposed to address the problem of underwater sound scattering by an elastic shell structure, which is assumed to be circular and that is buried in a fluid seabed bellow a water waveguide. The interior of the shell is filled with a fluid that may have different properties from the host medium. The analysis is performed by coupling analytical solutions developed both for sound propagation in the waveguide and in the vicinity of the circular hollow pipeline. The coupling between solutions is performed using the method of fundamental solutions. This strategy allows a compact description of the propagation medium while being very accurate and highly efficient from the computational point of view

The method of fundamental solutions for the analysis of infinite 3D sonic crystals

[EN] The use of periodic structures in acoustic applications has interested the scientific community in the last two decades. Although in-depth research has been thoroughly performed, many issues have still not been solved. Computational analysis of sonic structures using realistic 3D models still poses significant problems, and most of the published results correspond to 2D problems. Analysing 3D problems of such structures using conventional methods demands large computational resources, which may be prohibitive. This paper proposes a new approach for such 3D problems making use of a highly efficient Method of Fundamental Solutions (MFS) approach to deal with sonic crystals made of 3D scatterers, infinitely repeated with constant spacing along one direction. The method makes use of a special form of the acoustic fundamental solutions which can be highly efficient in such analysis, while allowing just the cell that is repeated to be effectively modelled. Verification of the model is provided by first comparing its results with those from an ACA-MFS model. Results are compared with those from a FDTD algorithm, and a parametric study is presented revealing the 3D character of the computed responses, and evidencing the formation of acoustic band-gaps at specific frequency bands associated with the Bragg effect.The EU funding support in the scope of COST (European Cooperation in Science and Technology) through the COST ActionPlease check funding information and confirm its correctness.
