Регулярно в мире терпит крушение большое количество крупных судов. Количество случаев крушения с каждым годом растет. Крушения происходят, в том числе, из-за значительных размеров судов, роста интенсивности движения на морских путях, роста скоростей движения, неблагоприятных метеорологических условий, недостатков современных навигационных систем. Исходя из этого, следует больше уделять внимание методикам и средствам спасения судна при крушении. В случае крушения судна, для спасения человеческих жизней и груза может быть использована преднамеренная посадка судна на мель. Актуальность исследования вопросов, связанных с преднамеренной посадкой на мель, подтверждается: разработкой новых методов стягивания судна с мели, разработкой в области создания безэкипажных судов, Международной конвенцией о подготовке и дипломировании моряков и несении вахты, которая требует от судоводителя: умения осуществлять преднамеренную посадку на мель, понимания основных действий в случае, если посадка на мель неизбежна и действий после посадки на мель. В работе рассматривается продольный спуск судна на воду вперед кормой. Приводится аналитическое доказательство того, что в первом приближении продольный спуск на воду схож с посадкой судна на мель. Приводятся соответствующие математические выкладки. Из приведенного доказательства следует вывод, что в практике судоходства, в аварийной ситуации, можно рассчитать посадку на мель так, что это может привести к спасению судна и как следствие его экипажа и пассажиров. A large number of large ships are wrecked on a regular basis in the world. The number of crash cases is growing every year. Wrecks occur, among other things, due to the significant size of ships, the growth of traffic on sea routes, the growth of traffic speeds, unfavorable meteorological conditions, and the shortcomings of modern navigation systems. Based on this, more attention should be paid to methods and means of rescuing a ship in case of a wreck. In the event of a shipwreck, deliberate grounding of the ship may be used to save lives and cargo. The relevance of the study of issues related to deliberate grounding is confirmed by: the development of new methods for pulling a ship aground, development in the field of the creation of unmanned vessels, the International Convention on the Training and Certification of Seafarers and Watchkeeping, which requires the boatmaster to: the ability to carry out deliberate grounding, an understanding of basic actions in the event that a grounding is imminent and of actions after a grounding. The paper considers the longitudinal launching of the vessel into the water forward stern. Analytical proof is given that, in the first approximation, the longitudinal launching is similar to the landing of a ship aground. The corresponding mathematical calculations are given. From the above evidence it follows that in the practice of shipping, in an emergency, it is possible to calculate the aground so that it can lead to the salvation of the vessel and, as a consequence, of its crew and passengers.

This article addresses the meaning and significance of the “world revolution of 1968,” as well as the historiography of 1968. I critically interrogate how the production of a narrative about 1968 and the creation of ethnic studies, despite its world-historic significance, has tended to perpetuate a limiting, essentialized and static notion of “the student” as the primary actor and an inherent agent of change. Although students did play an enormous role in the events leading up to, through, and after 1968 in various parts of the world—and I in no way wish to diminish this fact—this article nonetheless argues that the now hegemonic narrative of a student-led revolt has also had a number of negative consequences, two of which will be the focus here. One problem is that the generation-driven models that situate 1968 as a revolt of the young students versus a presumably older generation, embodied by both their parents and the dominant institutions of the time, are in effect a sociosymbolic reproduction of modernity/coloniality’s logic or driving impulse and obsession with newness. Hence an a priori valuation is assigned to the new, embodied in this case by the student, at the expense of the presumably outmoded old. Secondly, this apparent essentializing of “the student” has entrapped ethnic studies scholars, and many of the period’s activists (some of whom had been students themselves), into said logic, thereby risking the foreclosure of a politics beyond (re)enchantment or even obsession with newness yet again.

AbstractWith the rapid onset of an unprecedented lifestyle due to the new coronavirus COVID-19 the world academic scene was forced to reform and adapt to the novel circumstances. Although online education cannot be regarded as a groundbreaking endeavour anymore in the21st century, its current character of exclusivity calls for deeper understanding of, and a sharper focus on the “end-consumer” thereof as well as more cautious procedures to be exercised while teaching. While millennials are no longer thought of as being born with a silver spoon in their mouth but with an iPad or any sort of device in their hand (irrespective of their social status), adults are more hesitant when coerced to alter course unexpectedly and turn to new methods of attaining their learning goals. This is why proper communicative approaches need to be thoroughly considered by online instructors. This article aims at presenting teachers with a set of strategies to employ when the beneficiaries of online academic education are adult learners.

Every great fiction book is a book that portrays the uniqueness of the universe and man, the difficulty of breaking that bond, or the weakening of its bond and the increase in human. The creation of such a book is beyond the reach of all creators, and not all works can illuminate the cultural, spiritual and moral status of any nation in the world by unraveling the underlying foundations of humanity. With the birth of Hoja Ahmad Yassawi's “Devoni Hikmat”, the Turkic nations were recognized as a nation with its own book of teaching, literally, the encyclopedia of enlightenment, truth and spirituality.

Resumo: Há um relativo depauperamento no tocante ao nosso conhecimento a respeito da relação entre a filosofia kantiana e a constituição da geografia moderna e, conseqüentemente, científica. Esta relação, quando abordada, o é - vezes sem conta - de modo oblíquo ou tangencial, isto é, ela resta quase que exclusivamente confinada ao ato de noticiar que Kant ofereceu, por aproximadamente quatro décadas, cursos de Geografia Física em Königsberg, ou que ele foi o primeiro filósofo a inserir esta disciplina na Universidade, antes mesmo da criação da cátedra de Geografia em Berlim, em 1820, por Karl Ritter. Não ultrapassar a pueril divulgação deste ato em si mesma só nos faz jogar uma cortina sobre a ausência de um discernimento maior acerca do tributo de Kant àfundamentação epistêmica da geografia moderna e científica. Abrir umafrincha nesta cortina denota, necessariamente, elucidar o papel e o lugardo “Curso de Geografia Física” no corpus da filosofia transcendental kantiana. Assim sendo, partimos da conjectura de que a “Geografia Física” continuamente se mostrou, a Kant, como um conhecimento portador de um desmedido sentido filosófico, já que ela lhe denotava a própria possibilidade de empiricização de sua filosofia. Logo, a Geografia Física seria, para Kant, o embasamento empírico de suas reflexões filosóficas, pois ela lhe comunicava a empiricidade da invenção do mundo; ela lhe outorgava a construção metafísica da “superfície da Terra”. Destarte, da mesma maneira que a Geografia, em sua superfície geral, conferiu uma espécie de atributo científico à validação do empírico da Modernidade (desde os idos do século XVI), a Geografia Física apresentou-se como o sustentáculo empírico da reflexão filosófica kantiana acerca da “metafísica da natureza” e da “metafísica do mundo”.THE COURSE OF PHYSICAL GEOGRAPHY OF IMMANUEL KANT(1724-1804): CONTRIBUTION FOR THE GEOGRAPHICALSCIENCE HISTORY AND EPISTEMOLOGYAbstract: There is a relative weakness about our knowledge concerningKant philosophy and the constitution of modern geography and,consequently, scientific geography. That relation, whenever studied,happens – several times – in an oblique or tangential way, what means thatit lies almost exclusively confined in the act of notifying that Kant offered,for approximately four decades, “Physical Geography” courses inKonigsberg, or that he was the first philosopher teaching the subject at anyCollege, even before the creation of Geography chair in Berlin, in 1820, byKarl Ritter. Not overcoming the early spread of that act itself only made usthrow a curtain over the absence of a major understanding about Kant’stribute to epistemic justification of modern and scientific geography. Toopen a breach in this curtain indicates, necessarily, to lighten the role andplace of Physical Geography Course inside Kantian transcendentalphilosophy. So, we began from the conjecture that Physical Geography hasalways shown, by Kant, as a knowledge carrier of an unmeasuredphilosophic sense, once it showed the possibility of empiricization of hisphilosophy. Therefore, a Physical Geography would be, for Kant, theempirics basis of his philosophic thoughts, because it communicates theempiria of the world invention; it has made him to build metaphysically the“Earth’s surface”. In the same way, Geography, in its general surface, hasgiven a particular tribute to the empiric validation of Modernity (since the16th century), Physical Geography introduced itself as an empiric basis toKantian philosophical reflection about “nature’s metaphysics” and the“world metaphysics” as well.Keywords: History and Epistemology of Geography, Physical Geography,Cosmology, Kantian Transcendental Philosophy, Nature.

The archives are generally sites where historians conduct research into our past. Seldom are they objects of research. Sabyasachi Bhattacharya traces the path that led to the creation of a central archive in India, from the setting up of the Imperial Record Department, the precursor of the National Archives of India, and the Indian Historical Records Commission, to the framing of archival policies and the change in those policies over the years. In the last two decades of colonial rule in India, there were anticipations of freedom in many areas of the public sphere. These were felt in the domain of archiving as well, chiefly in the form of reversal of earlier policies. From this perspective, Bhattacharya explores the relation between knowledge and power and discusses how the World Wars and the decline of Britain, among other factors, effected a transition from a Eurocentric and disparaging approach to India towards a more liberal and less ethnocentric one.

Through this chapter the crafting of compilations is explored as an act, art, and expression of music making, illuminating the listeners’ and compilers’ positions as cocreators of meaning, function, and purpose. Music becomes repositioned and repurposed as found or sound objects that pass through Gaston Bachelard’s triptych of resonance, repercussion, and reverberations, a process of music speaking to so as to speak for individuals’ deeply personal and significantly meaningful experiences. The chapter addresses the question, “What motivates someone to partake in this personally meaningful, vulnerable, and artistic endeavor?” Using Josef Pieper’s conceptions of leisure as celebration, an orientation toward the wonderful, and an act of affirmation, the chapter concludes that the creation and crafting of compilations (e.g., mix tape) affords poetic spaces for connection, enchantment, felt-aliveness, or what Max van Manen called an “incantative, evocative speaking, a primal telling, [whose] aim [is] to involve the voice in an original singing of the world.”

The creation of the Islamic State in Iraq and Sham (ISIS) changed the nature of jihadism worldwide. For a few years (2014–2017) it exemplified the destructive capacity of jihadism and created a new utopia aimed at restoring the past greatness and glory of the former caliphate. It also attracted tens of thousands of young wannabe combatants of faith (mujahids, those who make jihad) toward Syria and Iraq from more than 100 countries. Its utopia was dual: not only re-creating the caliphate that would spread Islam all over the world but also creating a cohesive, imagined community (the neo-umma) that would restore patriarchal family and put an end to the crisis of modern society through an inflexible interpretation of shari‘a (Islamic laws and commandments). To achieve these goals, ISIS diversified its approach. It focused, in the West, on the rancor of the Muslim migrants’ sons and daughters, on exoticism, and on an imaginary dream world and, in the Middle East, on tribes and the Sunni/Shi‘a divide, particularly in the Iraqi and Syrian societies.

Mark Grimshaw-Aagaard addresses the role of sound in the creation of presence in virtual and actual worlds. He argues that imagination is a central part of the generation and selection of perceptual hypotheses—models of the world in which we can act—that emerge from what Grimshaw-Aagaard calls the “exo-environment” (the sensory input) and the “endo-environment” (the cognitive input). Grimshaw-Aagaard further divides the exo-environment into a primarily auditory and a primarily visual dimension and he deals with the actual world of his own apartment and the virtual world of first-person-shooter computer games in order to exemplify how we perceptually construct an environment that allows for the creation of presence.

AbstractGreat efforts are devoted to end the HIV epidemic as it continues to have profound public health consequences in the United States and throughout the world, and new interventions and strategies are continuously needed. The use of HIV sequence data to infer transmission networks holds much promise to direct public heath interventions where they are most needed. As these new methods are being implemented, evaluating their benefits is essential. In this paper, we recognize challenges associated with such evaluation, and make the case that overcoming these challenges is key to the use of HIV sequence data in routine public health actions to disrupt HIV transmission networks.
