negro e a marginalização social
Authors: Da Rosa Müller Henrique
Published: April 2021

Através de uma abordagem histórico-sociológica, busquei propor uma articulação entre a produção cientifica negra, a teoria decolonial e a teoria marxista. tendo como objetivo analisar a marginalização e preconceito desenvolvidos pelas diferentes estratégias e projetos de Estado na história do Brasil, desde a escravidão negra ao capitalismo global contemporâneo. Este ensaio teórico não encerra as diversas discussões em torno dos debates étnico-raciais, abertos no contemporâneo da produção científica. Ao contrário, torna-se uma contribuição ensaística na tentativa de evidenciar as múltiplas relações desenvolvidas pelo preconceito e a luta de classes observada na realidade social brasileiras.

High-Frequency Ventilation in the Treatment of Acute Respiratory Failure
Authors: Perepelitsa Svetlana A. , Kuzovlev Artem N.
Published: April 2021

The need for respiratory therapy can reach 90% depending on the category of the intensive care unit and intensive care unit (ICU). Currently is a wide selection of respiratory therapy methods, including fully controlled mechanical ventilation and assist ventilation. The widespread use of mechanical ventilation and its varieties significantly reduced the mortality of ICU patients. However, the mortality of patients from acute respiratory distress syndrome, nosocomial pneumonia, and newborns with respiratory disorders remains high. High-frequency mechanical ventilation (HFMV) is an alternative treatment for severe respiratory failure, but the frequency of use is not yet sufficient. Three main types of HF ventilation is currently available: high-frequency positive pressure ventilation (HFPPV), high-frequency jet ventilation (HFJV) and high-frequency oscillatory ventilation (HFOV). There is an opportunity to choose a specific mode which will be most applicable for a particular patient. The use of the HFOV method allows the successful treatment of newborns with severe respiratory failure due to primary surfactant deficiency, meconial aspiration or multiple organ failure. Recently high amount of publications appeared on the possibilities of non-invasive HFMV in both adult patients and in pediatrics. This mini-review is devoted to this problem.
Biomarkers of Carotid Stenosis

Published: April 2021

Early recognition of rupture-prone atherosclerotic lesions in patients with high-graded carotid stenosis is an important clinical problem for preventing ischemic stroke. Various pathophysiological mechanisms are responsible for the progression and instability of plaques, such as changes in lipid composition, infiltration by immunoinflammatory cells and degradation of the extracellular matrix of the vascular wall by matrix metalloproteinases, enhanced inflammatory response and plaque neovascularization. These features are the main cause of plaque rupture and, as a consequence, neurologic symptoms. Therefore, matrix metalloproteinases and inflammatory factors can serve as possible markers for patients with severe unstable stenosis of carotid arteries. Due to the heterogeneity of atherosclerotic lesions, only one biomarker is not enough to reliably predict the development of a stroke. The use of a combination of biomarkers is better correlated with clinical data and, therefore, exceeds the analysis of individual factors. To increase the overall sensitivity and specificity and more reliable diagnosis of stroke in patients with symptomatic and asymptomatic carotid stenosis, the biomarker panel should include independent biomarkers. Further preclinical experiments and clinical trials are needed to assess the significance and precise definition of the threshold levels of such biomarkers before they can be used in clinical practice.

Me concentraré en algunos pasajes de las Enéadas y de la Teología Platónica para examinar los diferentes modos en que cada uno de ellos integra esa tríada en el ámbito intelectual con vistas a analizar la crítica que Proclo emprende del sistema plotiniano a propósito de la conformación del primer grado de generación.
The Demiurge in Ioane Petritsi’s Commentary on Proclus’ Elements of Theology
Authors: Alexidze Lela
Published: April 2021

Ioane Petritsi, the twelfth century Georgian Christian Neoplatonist, wrote a commentary on Proclus’ Elements of Theology. In his work Petritsi goes far beyond the material contained in Proclus’ Elements, discussing the issues which are the subject of other treatises of ancient Greek philosophers. The aim of this paper is to analyze Petritsi’s point of view on the creator of the visible world, i.e. the demiurge of Plato’s Timaeus. In Petritsi’s commentary, on the one hand, the features of the supreme One and the demiurge as producers of the universe are in certain cases quasi identical, although on the other hand, the demiurge represents a lower level of intellect than the true being and in some cases is absent in places where a reader, following the context of Petritsi’s commentary, expects his presence.

Foreign experience in preventing certain threats to criminological security of education
Authors: Sidorova Ekaterina
Published: April 2021

The author turns to the study of individual preventive measures implemented abroad in order to combat negative factors that threaten the criminological security of the education sector. We are talking about the prevention of suicides of schoolchildren and students, extremism among students, drug addiction, substance abuse and alcoholism among participants in educational relations. The author analyzes the preventive experience of Australia, Great Britain, the Netherlands, Switzerland, Japan, Scotland, the USA and a large number of other countries. For example, special school prevention programs are being introduced to combat suicides among students studying abroad. Prevention of extremism among schoolchildren and students abroad is based on the introduction of special state directives and brochures into the educational process. Prevention of drug addiction and alcoholism among participants in educational relations is based on the interaction of law enforcement agencies with teachers. Based on the analysis, the author concludes that some positive foreign experience in combating negative social phenomena that exist in the educational environment should be tested in Russia.

The issue of more detailed legal regulation of restrictions, prohibitions and requirements imposed on an internal Affairs officer in order to counteract corruption is noted as a significant issue that urgently of the institution of disciplinary coercion.

Conclusions: in order to make the current legislation of the Russian Federation more systematic, it is proposed to combine the norms on disciplinary coercion in the police considered in the article in a single source. In our opinion, the positive effect of the above-mentioned consolidation of norms will be achieved due to the fact that both the police Department employees and employees of the departments for the prevention of corruption offenses will turn to a single source.
Features of determining objective and subjective signs of market manipulation: questions of theory and practice
Authors: Lunina Irina
Published: April 2021

The article is devoted to research of features of legal evaluation of the signs of the acts set forth in article 1853 criminal code. A criminal-legal analysis is carried out, and proposals are made to improve the design of this corpus delicti. Conclusions are drawn that the current version of the criminal law does not take into account the possibilities of transformation of illegal activities of subjects in the conditions of continuous development of the financial market. In this regard, as an additional form of information manipulation, in addition to the deliberate dissemination of false information, should be considered not only active but also passive actions of the person, as well as to exclude the direct dependence of the qualification of an act as a crime against damage, loss caused by an act or benefits received by the infringer.
Institute of Self-defense in the criminal law field. Review of the monograph by E.V. Lucchi, A.V. Shulga “Necessary defense in case of encroachments on family members: criminal-legal and criminological aspects” (Moscow: “Yurlitinform” Publ., 2021. 176 p.)
Authors: Zuyeva Yulia
Published: April 2021

The necessary defense is an inalienable right of every person, consisting in the protection of life and health, rights and legitimate interests belonging both to himself and to third parties. It is necessary to agree with the authors of the monograph that this form of self-defense is "one of the oldest institutions of criminal law, which since ancient times is based mainly on the instinct of self-preservation of a person living in society, and the desire to protect themselves from the surrounding dangers of domestic and social nature" (p. 7). The" merits " of the legal institution under consideration should also include the fact that it has a really effective deterrent potential against crime, since the prospect of receiving a tough rebuff from the defender has a much greater impact on the attacker than the probability of being in the hands of justice. At the same time, a qualified legal assessment of all aspects of the incident determines the distribution of the "victim" and "accused" statuses, which are sometimes repeatedly "exchanged" by participants in numerous conflicts during the judicial and investigative proceedings. An equally problematic aspect is the possibility of provoking an attack with the subsequent imitation of the state of the necessary defense from hooligan, selfish or other deviant motives. Accordingly, the correct legal assessment of the application of this form of self-defense in practice is a highly significant element of law enforcement. This is what determines the value of the institute of legal self-defense as an object of scientific research.

Craft Beer Tourism in Thailand
Authors: Chirakranont Rangson , Sunanta Sirijit
Published: April 2021

The craft beer movement and craft beer tourism are a new global phenomenon that has reached various parts of the world. However, the literature on craft beer tourism mostly focuses on traditional origins of craft beer in Western countries—the US, Australia, and European countries.
This research note illustrates how a study of the Thai craft beer movement and craft beer tourism could contribute to the existing body of knowledge. The consumption of non-Western people in non-Western places has been underrepresented in the literature of food and beverage tourism. The craft
beer movement has spread to Thailand via urban middle-class Thais who brought the passion for and knowledge of home brewing from the West to Thailand. Brewing lessons, brewery visits, and craft beer events/ festivals have functioned as community building activities for Thai craft beer enthusiasts
as well as the main craft beer distribution channel. Craft beer consumption continues to grow despite the Thai alcoholic production law that prohibits home brewing. For future studies, different craft beer tourism activities in Thailand should be analyzed for 1) the adoption of the experience
economy framework, 2) the formation of the consumption community, 3) the roles of various stakeholders who differentially contribute to and benefit from craft beer tourism activities, and 4) the role of foreign tourists in the development of craft beer tourism in Thailand.

If we find we are alone in the universe, or at least find no evidence for life anywhere else, does this suggest the universe was created for us? This seems like an awful waste of space. Lawrence Krauss argues that an intelligent designer should have done better. He traces the history of the causation versus correlation debate. If life is just a cosmic accident, we can still revel in our moment.

realismo "full hd" de Juan Francisco Ferré
Authors: Florenchie Amélie
Published: April 2021

A partir de las teorías sobre el simulacro del filósofo francés Jean Baudrillard, así como del análisis del posmodernismo como resultado de la lógica cultural del capitalismo tardío de Fredric Jameson, y de los postulados más recientes de Eloy Fernández Porta sobre la evolución de la cultura hacia el paradigma estético del afterpop, nos proponemos estudiar en este artículo las características del “realismo de alta definición” definido por Juan Francisco Ferré a propósito de su penúltima novela Providence (Anagrama, 2009). Se trata de proponer una reflexión crítica sobre el poder de la imagen digital así como mostrar que la ficción literaria es todavía capaz de competir con la realidad virtual.

The Rotation of the Nonrigid Earth at the Second Order. II. The Poincaré Model: Nonsingular Complex Canonical Variables and Poisson Terms
Authors: Getino Juan , Escapa Alberto , Ferrándiz José Manuel , Baenas Tomás
Published: April 2021

We develop a Hamiltonian analytical theory for the rotation of a Poincaré Earth model (rigid mantle and liquid core) at the second order with respect to the lunisolar potential and moving ecliptic term. Since the Andoyer variables considered in the first-order solution present virtual singularities, i.e., vanishing divisors, we introduce a set of nonsingular complex canonical variables. This choice allows for applying the Hori canonical perturbation method in a standard way. We derive analytical expressions for the first- and second-order solutions of the precession and nutation of the angular momentum axis (Poisson terms). Contrary to first-order theories, there is a part of the Poisson terms that does depend on the Earth’s structure. The resulting numerical amplitudes, not incorporated in the International Astronomical Union nutation standard, are not negligible considering current accuracies. They are at the microarcsecond level for a few terms, with a very significant contribution in obliquity of about 40 μas for the nutation argument with period −6798.38 days. The structure-dependent amplitudes present a large amplification with respect to the rigid model due to the fluid core resonance. The features of such resonance, however, are different from those found in first-order solutions. The most prominent is that it does not depend directly on the second-order nutation argument but rather on the combination of first-order arguments generating it. It entails that some first-order approaches, like those based on the transfer function, cannot be applied to obtain the second-order contributions.
Dynamical Avenues for Mercury’s Origin. I. The Lone Survivor of a Primordial Generation of Short-period Protoplanets
Authors: Clement Matthew S. , Chambers John E. , Jackson Alan P.
Published: April 2021

The absence of planets interior to Mercury continues to puzzle terrestrial-planet formation models, particularly when contrasted with the relatively high derived occurrence rates of short-period planets around Sun-like stars. Recent work proposed that the majority of systems hosting hot super-Earths attain their orbital architectures through an epoch of dynamical instability after forming in quasi-stable, tightly packed configurations. Isotopic evidence seems to suggest that the formation of objects in the super-Earth-mass regime is unlikely to have occurred in the solar system as the terrestrial-forming disk is thought to have been significantly mass deprived starting around 2 Myr after the formation of calcium-aluminum-rich inclusions—a consequence of either Jupiter’s growth or an intrinsic disk feature. Nevertheless, terrestrial-planet formation models and high-resolution investigations of planetesimal dynamics in the gas-disk phase occasionally find that quasi-stable protoplanets with mass comparable to that of Mars emerge in the vicinity of Mercury’s modern orbit. In this paper, we investigate whether it is possible for a primordial configuration of such objects to be cataclysmically destroyed in a manner that leaves Mercury behind as the sole survivor without disturbing the other terrestrial worlds. We use numerical simulations to show that this scenario is plausible. In many cases, the surviving Mercury analog experiences a series of erosive impacts, thereby boosting its Fe/Si ratio. A caveat of our proposed genesis scenario for Mercury is that Venus typically experiences at least one late giant impact.

Enceladus’s long-lived plume of ice grains and water vapor makes accessing oceanic material readily achievable from orbit (around Saturn or Enceladus) and from the moon’s surface. In preparation for the National Academies of Sciences, Engineering and Medicine 2023–2032 Planetary Science and Astrobiology Decadal Survey, we investigated four architectures capable of collecting and analyzing plume material from orbit and/or on the surface to address the most pressing questions at Enceladus: Is the subsurface ocean inhabited? Why, or why not? Trades specific to these four architectures were studied to allow an evaluation of the science return with respect to investment. The team found that Orbilander, a mission concept that would first orbit and then land on Enceladus, represented the best balance. Orbilander was thus studied at a higher fidelity, including a more detailed science operations plan during both orbital and landed phases, landing site characterization and selection analyses, and landing procedures. The Orbilander mission concept demonstrates that scientifically compelling but resource-conscious Flagship-class missions can be executed in the next decade to search for life at Enceladus.
Spam Detection Based on Feature Evolution to Deal with Concept Drift
Authors: Henke Marcia , Santos Eulanda , Souto Eduardo , Santin Altair O
Published: April 2021

Electronic messages are still considered the most significant tools in business and personal applications due to their low cost and easy access. However, e-mails have become a major problem owing to the high amount of junk mail, named spam, which fill the e-mail boxes of users. Several approaches have been proposed to detect spam, such as filters implemented in e-mail servers and user-based spam message classification mechanisms. A major problem with these approaches is spam detection in the presence of concept drift, especially as a result of changes in features over time. To overcome this problem, this work proposes a new spam detection system based on analyzing the evolution of features. The proposed method is divided into three steps: 1) spam classification model training; 2) concept drift detection; and 3) knowledge transfer learning. The first step generates classification models, as commonly conducted in machine learning. The second step introduces a new strategy to avoid concept drift: SFS (Similarity-based Features Se- lection) that analyzes the evolution of the features taking into account similarity obtained between the feature vectors extracted from training data and test data. Finally, the third step focuses on the following questions: what, how, and when to transfer acquired knowledge? The proposed method is evaluated using two public datasets. The results of the experiments show that it is possible to infer a threshold to detect changes (drift) in order to ensure that the spam classification model is updated through knowledge transfer. Moreover, our anomaly detection system is able to perform spam classification and concept drift detection as two parallel and independent tasks.
Formal Verification of Cloud and Fog Systems:A Review and Research Challenges

Published: April 2021

Cloud and Fog computing have been widely recognized as attractive solutions in both academic and industrial sectors. Despite their benefits, the adoption of Cloud and Fog computing still have considerable challenges to be handled due to the increase of client requirements. A crucial issue, in this context, is how to verify the correctness of Cloud and Fog systems. The use of formal methods is an efficient mean which provides a real help for the designer to evaluate the behaviour of a system and prevent errors before its implementation. In this paper, we present a systematic literature review (SLR) on the current state of the art in this field. We collect the existing studies on the use of formal methods for proving the correctness of Cloud and Fog systems. The proposed approaches are compared based on some technical properties such as the verification methods, the verification tools, the considered properties, and the application domains. In addition, future directions which need more investigations are presented. We believe that our paper will be useful for industry and academic researchers to understand the existing contributions that deal with the cor- rectness of Cloud and Fog systems. Moreover, it helps them to address several gaps in the literature.

La mort de Dieu chez Lacan
Authors: Dalzell Tom
Published: April 2021

Cet article examine le thème de la mort de Dieu dans l’œuvre de Lacan et il indique quelques convergences avec la théologie chrétienne dans la postmodernité. Il distingue l’athéisme de Lacan de celui de Freud. Et bien qu’il relie le réel de la jouissance Autre à l’expérience des mystiques, il démontre que l’athéisme du Lacan tardif, qui plaide pour un Dieu en dehors du symbolique, n’est pas le mysticisme.
Quelques remarques sur le rôle des affects dans l’œuvre de Freud
Authors: Constantopoulos Michel
Published: April 2021

Pour Freud, dès le départ, tout état psychique est, dans une certaine mesure, affectif. Son originalité consiste à avoir commencé par opposer affect et représentation, pour en faire par la suite les deux composantes de la pulsion. La séparation de l’affect d’avec sa représentation a permis dans un premier temps une nouvelle conception du symptôme névrotique et donna naissance à la thérapie cathartique. Mais ce n’est qu’avec la théorie des pulsions que ces deux destins divergents de la représentance psychique ont accédé à une nouvelle articulation, ouvrant la voie à une théorie de l’angoisse en tant que liée au réel de la jouissance et cause du refoulement. Nous proposons ici de reparcourir ce cheminement afin d’en dégager les étapes successives.
Inov’On

Published: April 2021

Cette étude de cas décrit les transformations organisationnelles du groupe Inov’On, créé à partir d’une PME innovante, prestataire de services et de dépannage pour les flexibles hydrauliques sur site (ex-Chronoflex). Le groupe est dirigé par Alexandre GERARD. Durant ces dernières années, Alexandre a diversifié son groupe et démultiplié sa taille ; néanmoins, il a rencontré de nombreux obstacles liés à la transformation de la stratégie, de la structure et de la culture des organisations en jeu. Ce cas invite à la réflexion sur les limites et les possibilités du modèle de l’« Entreprise Libérée », du point de vue de la motivation organisationnelle, de la flexibilité structurelle (agilité organisationnelle) et de la gestion des connaissances en matière d’innovation.
