    Historiquement marqué par l’opposition entre l’organique et le psychique, l’hystérie continue au centre des débats entre d’influents savoirs tels que la psychanalyse et la psychiatrie. En mettant en contre-position deux conceptions - l’une qui défend l’existence d’un monde indépendant de la psyché humaine (réalisme) et l’autre qui la nie (anti-réalisme) - nous cherchons à penser comment s’est construit le concept de l’hystérie. Suivant le mouvement scientifique du siècle XIX, le médecin français Jean-Martin Charcot se sert de la photographie, sous-entendue à l’époque comme “véritable rétine” du scientiste, pour créer une typologisation de l’être humain. En insérant la construction de ce savoir en son contexte socioculturel, il est possible de se poser plusieurs questions sur son objectivité. Notre conception est de penser qu’une critique réflexive sur la formation des concepts apporte des éléments pour un meilleur exercice de l’altérité au sein de la psychopathologie.The concept of hysteria has been historically situated in the opposition between the organic and the mental. It continues to be at the center of controversies between important areas, such as psychoanalysis and psychiatry. We tried to elucidate the origin of the concept of hysteria by contrasting a conception that defends the existence of a world independent of the human mind (realism), and another that denies it (antirealism). Following the scientific trend of the 19th century, the French physician Jean-Martin Charcot used photography - at that time photography was seen as the scientist’s “true retina” - to create a typology of human beings. Situating this construction of knowledge and its sociocultural context provokes a questioning as to its objectivity. Our suggestion is that to think in a critical way about the origin of the concepts gives us elements for a better exercise of alterity in psychopathology.Históricamente marcado por la oposición entre lo orgánico y lo psicológico, el concepto de histeria sigue en el centro de la controversia entre los conocimientos influyentes como lo de psicoanálisis y la psiquiatría.

    Nowadays we continue to observe a big and fast growth of wireless com-munication usage due to the increasing number of access points, and fields of application of this technology. Furthermore, these new usages can require higher speed and better quality of service in order to create market. As example we can have: live 4K video transmission, M2M (Machine to Machine communication), IoT (Internet of Things), Tactile Internet, between many others. As a consequence of all these factors, the spectrum is getting overloaded with communications, increasing the interference and affecting the system's per-formance. Therefore a different path of ideas has been followed and the commu-nication process has been taken to the next level in 5G by the usage of big arrays of antennas and multi-stream communication (MIMO systems) which in a greater scale are called massive MIMO schemes. These systems can be combined with an SC-FDE (Single-Carrier Frequency Domain Equalization) scheme to im-prove the power efficiency due to the low envelope fluctuations. This thesis focused on the equalization in massive MIMO systems, more specifically in the FDE (Frequency Domain Equalization), studying the perfor-mance of different approaches, namely ZF (Zero Forcing), EGD (Equal Gain De-tector), MRD (Maximum Ratio Detector), IB-DFE (Iterative Block Decision Feed-back Equalizer) and a proposed receiver combining MRD (or EGD) and IB-DFE.With this approach we want to minimize the ICI (Inter Carrier Interference) in order to have almost independent data streams and to produce a low complexity code, so that the receiver's performance doesn't affect the total system's perfor-mance, with a final objective of increasing the data throughput in a great scale

    Momentum risk: An approach following the correlations between active stocks

    Get PDF
    The momentum anomaly has been widely documented in the literature. However, there are still many issues where there is no consensus and puzzles left unexplained. One is that strategies based on momentum present a level of risk that is inconsistent with the diversification that it offers. Moreover, recent studies indicate that this risk is variable over time and mostly strategy-specific. This work project hypothesises and proves that this evidence is explained by the portfolio constitution of the momentum strategy over time, namely the covariance and correlation between companies in the top and down deciles and across them.UNL - NSB

    Thinking about the meaning of teaching and learning geographically is fundamental to understand the dimensions of reality and has to do with the way we look at the world, the perceptions we build when we teach Geography. The article discusses the results of a work carried out at Agricultural Family School (EFA) Dom Fragoso, sharpening our lenses to analyze how we are reasoning geographically, for this we are highlighting that three dynamics were carried out in Geography classes with the 1st and 2nd grades of 2022 in order to understand this construction. We bring as examples the three dynamics that were: The drawing of sketches of the communities, the mental map and the photograph, which help in the construction of a geographical reasoning. The work was carried out through a qualitative approach, which will allow a significant understanding of what is proposed. In dialogue with this work, we highlight the following authors, CALLAI (2005), CAVALCANTI (2019), GUSMÃO (2021), STRAFORINI (2018). We can conclude that reasoning geographically starts with a school work and remains for life, this is what should to think about doing in the classroom: an everyday, spatial, planned Geography that dialogues with a consistent theoretical and practical bases.Pensar el sentido de enseñar y aprender geográficamente es fundamental para comprender las dimensiones de la realidad y tiene que ver con la forma en que miramos el mundo, las percepciones que construimos al enseñar Geografía. El artículo discute los resultados de un trabajo realizado en la Escuela Família Agrícola (EFA) Dom Fragoso, afilando nuestras lentes analizar como estamos razonando geográficamente, para eso destacamos que se realizaron tres dinámicas en las clases de Geografía con el 1° y 2° años del bachillerato del año de 2022 para realizar esta construcción. Traemos como ejemplos las tres dinámicas que fueron: El dibujo de croquis de las comunidades, el mapa mental y la fotografía, que ayudan en la construcción de un razonamiento geográfico. El trabajo se realizó a través de un enfoque cualitativo, lo que permitirá una comprensión significativa de lo que se propone. En diálogo con esta obra, destacamos los siguientes autores, CALLAI (2005), CAVALCANTI (2019), GUSMÃO (2021), STRAFORINI (2018).

    This study proposes a field study, based on a literature review, about the applications and impacts of Industry 4.0 (I4.0) in the biopharmaceutical sector. The world is facing a new industrial revolution and the central idea is the integration between the virtual and the real world through elements that will allow for a greater degree of automation and digitization of processes. The production of medicines via biological processes is a booming domain in the pharmaceutical sector, that involves extraordinary technological challenges. The fieldwork, carried out between August 2019 and February 2020, involved semi-structured interviews with managers of pharmaceutical companies and specialists in the I4.0 theme. The interviews allowed for the identification of trends and key benefits and barriers for implementing I4.0 in the biopharmaceutical sector. While the perceptions were considerably diversified, benefits in productivity, competitiveness and quality ranked among the most scored items. The main barriers, highlighted by the interviewees, refer to the need to break organizational cultural standards, the regulatory requirements, the lack of organizational strategies for implementation, and the lack of qualified professionals. This work offers a contribution to the biopharmaceutical sector and reinforces the imminent need for companies to adapt to this new reality.publishe

    NASAs Mid-Atlantic Communities and Areas at Intensive Risk Demonstration: Translating Compounding Hazards to Societal Risk

    Get PDF
    Remote sensing provides a unique perspective on our dynamic planet, tracking changes and revealing the course of complex interactions. Long term monitoring and targeted observation combine with modeling and mapping to provide increased awareness of hydro-meteorological and geological hazards. Disasters often follow hazards and the goal of NASAs Disasters Program is to look at the earth as a highly coupled system to reduce risk and enable resilience. Remote sensing and geospatial science are used as tools to help answer critical questions that inform decisions. Data is not the same as information, nor does understanding of processes necessarily translate into decision support for disaster preparedness, response and recovery. Accordingly, NASA is engaging the scientific and decision-support communities to apply remote sensing, modeling, and related applications in Communities and Areas at Intensive Risk (CAIR). In 2017, NASAs Applied Sciences Disasters Program hosted a regional workshop to explore these issues with particular focus on coastal Virginia and North Carolina. The workshop brought together partners in academia, emergency management, and scientists from NASA and partnering federal agencies to explore capabilities among the team that could improve understanding of the physical processes related to these hazards, their potential impact to changing communities, and to identify methodologies for supporting emergency response and risk mitigation. The resulting initiative, the mid-Atlantic CAIR project, demonstrates the ability to integrate satellite derived earth observations and physical models into actionable, trusted knowledge. Severe storms and associated storm surge, sea level rise, and land subsidence coupled with increasing populations and densely populated, aging critical infrastructure often leave coastal regions and their communities extremely vulnerable. The integration of observations and models allow for a comprehensive understanding of the compounding risk experienced in coastal regions and enables individuals in all positions make risk-informed decisions. This initiative uses a representative storm surge case as a baseline to produce flood inundation maps. These maps predict building level impacts at current day and for sea level rise (SLR) and subsidence scenarios of the future in order to inform critical decisions at both the tactical and strategic levels. To accomplish this analysis, the mid-Atlantic CAIR project brings together Federal research activities with academia to examine coastal hazards in multiple ways: 1) reanalysis of impacts from 2011 Hurricane Irene, using numerical weather modeling in combination with coastal surge and hydrodynamic, urban inundation modeling to evaluate combined impact scenarios considering SLR and subsidence, 2) remote sensing of flood extent from available optical imagery, 3) adding value to remotely sensed flood maps through depth predictions, and 4) examining coastal subsidence as measured through time-series analysis of synthetic aperture radar observations. Efforts and results are published via ArcGIS story maps to communicate neighborhoods and infrastructure most vulnerable to changing conditions. Story map features enable time-aware flood mapping using hydrodynamic models, photographic comparison of flooding following Hurricane Irene, as well as visualization of heightened risk in the future due to SLR and land subsidence

    A térmita de madeira seca das Índias Ocidentais, a Cryptotermes brevis (Walker, 1953) (Isoptera: Kalotermitidae) está perfeitamente estabelecida nos Açores, sendo considerada uma praga urbana com grande impacto económico e social pelos graves prejuízos que causa, através da destruição estrutural, principalmente das madeiras de suporte dos telhados. Espera-se com esta contribuição: i) determinar qual o produto com a maior taxa de absorção em todas as madeiras usadas na estrutura dos telhados açorianos; ii) contribuir de uma forma decisiva para que as empresas dos Açores possam adoptar esta prática no tratamento de todas as madeiras a usar nas estruturas; iii) contribuir, indirectamente, para a redução do ataque das térmitas nas madeiras, através do seu tratamento com estes produtos, tendo em vista o controlo desta praga nas zonas urbanas afectadas. De todos os seis produtos utilizados, o XT-2000 (d-limonene), líquido com propriedades insecticidas extraído da casca de citrinos, foi o que melhor foi absorvido e se difundiu no interior da madeira tratada em todas as modalidades ensaiadas. Analisando esta capacidade de difusão no interior da madeira por cada tipo de produto e atendendo ao facto de se tratar de madeira do cerne ou do borne (superfície), o XT-2000 (d-limonene) e o TERMINATE (cialotrina) foram os que registaram a maior percentagem de absorção. Na madeira do cerne, o WOCOSEN (permetrina) foi o que melhor foi absorvido por todas as madeiras. É de referir que a acácia, o sapé e o eucalipto foram as madeiras que registaram a menor taxa de absorção após a aplicação dos produtos ensaiados.ABSTRACT: The West Indian drywood termite, Cryptotermes brevis (Walker, 1953) (Isoptera: Kalotermitidae), is a well-established and serious pest of structural wood in the Azores. It is therefore important to study different ways to fight against this insect, and among the several research studies in progress, in these contribution we discuss the rate of diffusion of six products inside five different kinds of wood that are normally used for construction of Azorean building roofs. Our aims are: i) to test which product is best absorbed in each type of wood tested and used in the building of Azorean roofs; ii) to contribute with methods that can be adopted by Azorean commercial enterprises to develop a domestic termite control industry; iii) to contribute indirectly in understanding the best woods and products we expect to enhance control of these pest in the affected urban areas. Of the six products tested, XT-2000 (d-limonene), a liquid extracted from citrus peels, gave the best results in terms of diffusion on all the wood types tested. When we compared the performance of each kind of product tested in both heartwood and sapwood, XT-2000 and TERMINATE were the products with the greatest amount absorbed in the woods tested. In the heartwood alone, WOCOSEN (permethrin) was the one that gave the best results for all woods. It is also important to note that acácia, sapé and Eucalyptus sp. were the woods that absorbed the least with all the products tested
