    This study aims to review the theme of the two main works of author Nassim Nicholas Taleb: The Black Swan: The impact of the highly improbable (2008) and Antifragile: Things that benefit from chaos (2014), with emphasis for the second, believing it to be a work that more fully contemplates their understanding of uncertainty, risk management and how we can take advantage of uncertain situations. A secondary objective is to understand his contribution and current relevance to the study related to uncertainty and randomness of events, in the sense that they do not follow a deterministic pattern and how concepts apparently related to the fields of statistics can be applied to everyday life, with several examples, allegories and metaphors that the author proposes throughout the works bringing his thoughts to the reality of readers in a more clear and objective way, the practical content of his narrative may be due to his practical experience in the financial market in the past and his current role in scientific production, Taleb certainly forms the "bridge" between empirical and theoretical knowledge. The uncertainty in Taleb's idea takes on a peculiar nuance with the allegory of the Black Swan, which are ev events that, because they are highly improbable and rare, seem to have no effect on our reality, but with the development of the theme we come to understand its relevance with both positive and negative consequences for reality and more than trying to predict it (which would be impossible), we are compelled to adopt a posture that makes us not only resilient, but better, more prepared and with fewer weaknesses, which the author will call “antifragile”. Therefore, those who adopt an antifragile posture should not be concerned about the lack of inherent information about the uncertain, but should be more concerned about learning that what is not within our reach at present, can bring us later in the future.Este estudo tem como principal objetivo fazer uma resenha sobre a temática das duas principais obras do autor Nassim Nicholas Taleb: O Cisne Negro: O impacto do altamente improvável (2008) e Antifrágil: Coisas que se beneficiam com o caos (2014), com destaque para a segunda acreditando se tratar de uma obra que contempla de forma mais completa seu entendimento sobre incerteza, gerenciamento de risco e como podemos tirar proveito de situações incertas. Um objetivo secundário está em entender sua contribuição e relevância atual para o estudo relacionado a incerteza e aleatoriedade dos eventos, no sentido que estes não seguem um padrão determinístico e como conceitos aparentemente relacionados aos campos da estatística podem se aplicar a vida cotidiana, com vários exemplos, alegorias e metáforas que o autor propõe ao longo das obras trazendo para realidade dos leitores seu pensamento de forma mais clara e objetiva, o teor pratico da sua narrativa talvez seja em função da sua experiência pratica no mercado financeiro no passado e sua atuação no presente na produção cientifica, Taleb certamente faz a “ponte” entre o conhecimento empírico e teórico. A incerteza na ideia de Taleb ganha uma nuance peculiar com a alegoria do Cisne Negro, que são eventos que por serem altamente improváveis e raros, parecem não ter efeito na nossa realidade, mas que com o desenvolvimento do tema passamos a entender sua relevância com consequências tanto positivas quanto negativas para a realidade, e mais do que tentar prevê-lo (o que seria impossível), somos compelidos a ter uma postura que nos tornem não apenas resilientes, mas melhores, mais preparados e com menos fraquezas, o que o autor vai chamar de “antifrágil”. Portanto, aquele que adota uma postura antifrágil não deve se preocupar com a falta de informações inerentes sobre o incerto, mas deve estar mais preocupado no aprendizado que aquilo que no presente não está ao nosso alcance, pode nós trazer posteriormente no futuro

    The Decline of Violent Conflicts: What Do The Data Really Say?

    Get PDF
    We propose a methodology to look at violence in particular, and other aspects ofquantitative historiography in general, in a way compatible with statistical inference, which needs to accommodate the fat-tailedness of the data and the unreliability of the reports of conflicts. We investigate the theses of “long peace” and drop in violence and find that these are statistically invalid and resulting from flawed and naive methodologies, incompatible with fat tails and non-robust to minor changes in data formatting and methodologies. There is no statistical basis to claim that “times are different” owing to the long inter-arrival times between conflicts; there is no basis to discuss any “trend”, and no scientific basis for narratives about change in risk. We describe naive empiricism under fat tails. We also establish that violence has a “true mean” that is underestimated in the track record. This is a historiographical adaptation of the results in Cirillo and Taleb (2016)

    44 f. : ill. ; 30 cm. (+ CD-Rom)L’identification des microstructures des défauts dans la structure Si-SiO2 est très importante, car elle nous permet de comprendre les mécanismes responsables de la dégradation des composants électroniques ; une fois ces mécanismes sont connus, cela nous permet d’agir sur le procède de fabrication pour diminuer ces défauts. Des recherches dans le domaine de la caractérisation se sont donc orientées vers la résonance de spin Ce mémoire a pour but d’apporter une contribution dans le domaine de la résonance paramagnétique pour l’identification des défauts atomique de Si-SiO2, pour une meilleure connaissance de l’origine physique des défauts et ainsi l’amélioration de la qualité des dispositifs et leur performance. Notre travail consiste a identifié les défauts dans le Si-SiO2, d’un transistor de puissance par la résonance paramagnétique, après plusieurs simulation nous somme arrivé à obtenir des signaux EDMR qui a détecté des défauts dans l’intervalle du champ magnétique de (6 a 8 mT). Les signaux que nous obtenus sont reproductibles malgré qu’à plusieurs reprise nous avons dû rebrancher tout les blocs du système et refaire les réglages des paramètres. Le matériel de caractérisation est fabriqué au CDTA .La détection des défauts avec cette méthode a été réalisée avec succès et nous pouvons ; il reste cependant à compléter cette technique par l’identification des défauts qui ne sera possible que lorsqu’un logiciel de traitement des données muni d’une base de données importante soit conçu pour l’identification et l’attribution de chaque type de signal au défaut correspondant. C’est ainsi que nous envisageons continuer dans ce domaine pour pouvoir réaliser cette base de données et ainsi compléter la technique

    “The Persian Prince in Londonâ€: Autoethnography and Positionality in Travels of Mirza Abu Taleb Khan

    No full text
    This paper explores the strategies and dynamics of Asian representation of the self and the colonial other in Travels of Mirza Abu Taleb Khan (1810). I argue that while the process of autoethnography in an early period of colonisation anticipates the subsequent oscillation between submission and resistance, such representations are made complex by the positionality of the author within his milieu. Taleb’s text is marked by the ambiguity of his response to colonialism, engaging in a simultaneous admiration and critique of western practices, a critique that is made possible by his identity as the “Persian Prince.†Yet in its history of print, circulation and reception it becomes a tool in the propagation of colonial power

Lett. 159, 559 (1989).""Author Institution: Department of Chemistry, University of MichiganThe ground internal rotation state (m=0)(m = 0) microwave spectrum of benzeneSO2\bullet SO_{2} has been reported previously [1]. It was shown that the spectrum is characteristic of an asymmetric top and displays a- and c-type transitions. It was also pointed out that numerous additional transitions occurred in the microwave spectrum of this complex. Using the Principal Axis Method (PAM) internal rotation Hamiltonian, the m=0m = 0 state transitions and the ``additional” transitions have been assigned. The existence of a rich spectrum for benzene SO2\bullet SO_{2} is due to the internal rotation of benzene about its C6C_{6} axis with a 6-fold potential barrier. The barrier height, V6V_{6}, is 0.3cm10.3 cm^{-1}. Transitions arising from internal rotation states as high as m = ±5\pm 5 were seen with our FTMW spectrometer. The internal rotation microwave spectrum of benzene-d6SO2d_{6}\bullet SO_{2} was also assigned. Further information on the magnitude of the tilt angle of the benzene plane and the tilt angle of the C2C_{2} axis of SO2SO_{2} with respect to the line joining their centers of mass was obtained

    Designing Pandemic Antifragility for Multimodal Transport Hubs

    No full text
    The outbreak of COVID-19 demonstrated the fragility of the transportation system and its Multimodal Transport Hubs (MTHs). Global travel reduced dramatically, leading to an existential crisis in MTHs. To cope with the pandemic, MTHs implemented multiple resilient measurements including social distancing, rapid testing regimes, and infrared cameras. Although these measurements are valuable tools, this research advocates to transcend resilient measures and move towards antifragility by applying a systems thinking approach. As Nassim Taleb (2013) defines: “Antifragility is beyond resilience or robustness. The resilient resists shocks and stays the same; the antifragile gets better.” Our goal is to contribute to a long-term future of the transportation system by transforming MTHs into a tool to effectuate antifragility during the management of health disruptions.Marketing and Consumer ResearchMechatronic DesignApplied Ergonomics and Desig

    Addressing domestic violence in primary care: What the physician needs to know

    No full text
    Domestic violence (DV) is quite prevalent and negatively impacts the health and mental wellbeing of those affected. Victims of DV are frequent users of health service, yet they are infrequently recognized. Physicians tend to treat the presenting complaints without addressing the root cause of the problem. Lack of knowledge on adequately managing cases of DV and on appropriate ways to help survivors is commonly presented as a barrier. This article presents the magnitude of the problem of DV in the Arab world, highlights the role of the primary care physician in addressing this problem, and provides practical steps that can guide the clinician in the Arab world in giving a comprehensive and culturally sensitive service to the survivors of DV. © 2014 Jinan Usta and Rim Taleb.Al-Nsour M, 2009, J FAM VIOLENCE, V24, P569, DOI 10.1007-s10896-009-9255-2; Ambuel B, 2003, J COMP FAM STUD, V34, P113; Ambuel B, 1998, J AGGRESS MALTREAT T, V1, P72; American Congress of Obstetricians and Gynecologists, SCREEN TOOLS DOM VIO; [Anonymous], PHYS OBL PREV ID TRE; [Anonymous], 2008, JORDAN POPULATION FA; [Anonymous], 2005, EGYPT DEMOGRAPHIC HL; [Anonymous], 2009, POPULATION REPORTS E; Basile K.
