First Time

Prior to globalization, crises were due to local or regional environmental abuses, leadership conflicts, local or regional climatic disasters, major epidemics or pandemics. The humanity of the beginning of the 21st century is facing for the first time a situation of global change on a planetary scale. The origin of this change is endogenous to the human species. Scientific and technological evolution has endowed humanity with powerful means of action that have transformed it into an important actor in the planetary ecology. This transformation is a consequence of fundamental factors that have reinforced each other. The use of fossil fuels returns to the environment gigantic amounts of solar energy fossilized in vegetable form during the billions of years of the primary, secondary and tertiary geological ages. The inevitable consequence is and will be more and more, global climate warming. This profound change could it surely causes serious adjustment disorders in all human societies. It is in this sense that the word "crisis" acquires its full and sinister meaning. A financial crisis is nothing more than the repetition of a psychosociological episode also recurrent in the evolution of the economy. A remarkable consequence is that man (biological, psychosocial) has become a "piece" of a huge machine, on a planetary scale, and his activities are increasingly conditioned by this machine created by himself. The concept of competitive advantage generally dominates economic thinking. This way of thinking reflects the historical situation of humanity. Until today, the human species could progress without limits towards greater use of its planetary environment. The waste did not have a negative ecological significance. The most sensible and appropriate objective, certainly, is not to lead all of humanity to share the waste that, by hyper-consumption, characterizes, for the moment, the societies considered as developed. A rational objective would be to guarantee to all humanity a level of life as satisfactory as possible, based on truly renewable planetary resources, assuming the need to keep the planet habitable.

AbstractAvoiding catastrophic climate change requires rapid decarbonization and improved ecosystem stewardship at a planetary scale. The carbon released through the burning of fossil fuels would take millennia to regenerate on Earth. Though the timeframe of carbon recovery for ecosystems such as peatlands, mangroves and old-growth forests is shorter (centuries), this timeframe still exceeds the time we have remaining to avoid the worst impacts of global warming. There are some natural places that we cannot afford to lose due to their irreplaceable carbon reserves. Here we map ‘irrecoverable carbon’ globally to identify ecosystem carbon that remains within human purview to manage and, if lost, could not be recovered by mid-century, by when we need to reach net-zero emissions to avoid the worst climate impacts. Since 2010, agriculture, logging and wildfire have caused emissions of at least 4.0 Gt of irrecoverable carbon. The world’s remaining 139.1 ± 443.6 Gt of irrecoverable carbon faces risks from land-use conversion and climate change. These risks can be reduced through proactive protection and adaptive management. Currently, 23.0% of irrecoverable carbon is within protected areas and 33.6% is managed by Indigenous peoples and local communities. Half of Earth’s irrecoverable carbon is concentrated on just 3.3% of its land, highlighting opportunities for targeted efforts to increase global climate security.

The article describes the process of tench growing (male and female species removed from set gear in the Volga river in the Astrakhan region) using experimental feedstuff "T", taking into account the fact that problems with artificial growing tench ( Тinca tinca ) appear first in the process of feeding when wild sires change to artificial food. The research took place on the base of the department of aquaculture and water bioresources of Astrakhan State Technical University in innovation centre "Bioaquapark - scientific and technical centre of aquaculture" in 2015. Special feed including components of animal origin - mosquito grab and sludge worm as an effective substitute to fish flour, as well as components of vegetable origin (carrot, parsley, pumpkin, wheatgrass) for domestication of tenches are offered for the first time. Food technology has been described. The exact composition of the formula, which is being licensed at the moment, is not disclosed. Feed "T", which has undergone biological analysis and is in accordance with organoleptic and physical standards was used for feeding tench female and male species during domestication period (60 days), along with food "Coppens" (Holland). Feed efficiency was determined according to survival and daily fish growth. Growth rate of females appeared more intensive than growth rate of males fed with experimental food "T". Daily growth changed depending on the types of food: from 0.3 ("Coppens") to 0.47 (experimental food) in females, from 0.25 ("Coppens") to 0.39 (experimental food) with males. Ability to survive among tench species fed with "Coppens" and experimental food made 60% and 100%, correspondingly. Nutricion of tench species with experimental food encouraged their domestication, which allowed using tench species in further fish breeding process in order to get offspring. The project was supported by the Innovation Promotion Fund in terms of the project "Development and implementation of the technique for the steady development of aquaculture: food "TechSA".

The Stranger

Study abroad begins long before students leave their own shores. The moment that children enter daycare, nursery school, or kindergarten for the first time, they are in foreign territory, and all their antennae are out, testing, absorbing, learning. They begin to develop the first of their many multiple identities. They are no longer "Johnny" or "Sarah" whom everyone knows and loves at home, but Johnny or Sarah whom no one knows nor initially cares about, and they have to figure out what kind of a new identity they will develop so the danger zone becomes as safe as home.  Leaving familiar surroundings- the sounds, smells, safety, and food of home- and realizing, quite abruptly, that they must learn to adapt to the demands and needs of strangers, is the first and the most challenging "trip abroad" they will ever take. They will use the same set of skills, more mature, more polished (we hope) when they arrive on a foreign campus and move in with a host family or into an international dormitory.  Learning to make the journey with ease, whether it is on the first day of school or the day a plane drops one in a foreign field, is a necessary accomplishment. We have to make friends out of our peers; we have to gain the respect of our teachers; we have to develop curiosity and concern about the people around us. The stranger they seem, the more there is to learn. To fear diversity is to fear life itself. As the world becomes smaller and more integrated, the more crucial this accomplishment grows.

The present work considers the dramatic changes the COVID-19 pandemic has brought to the global economy, with particular emphasis on energy. Focusing on the European Union, the article discusses the opportunities policy makers can implement to reduce the climate impacts and achieve the Paris Agreement 2050 targets. The analysis specifically looks at the fossil fuels industry and the future of the fossil sector post COVID-19 pandemic. The analysis first revises the fossil fuel sector, and then considers the need for a shift of the global climate change policy from promoting the deployment of renewable energy sources to curtailing the use of fossil fuels. This will be a change to the current global approach, from a relative passive one to a strategically dynamic and proactive one. Such a curtailment should be based on actual volumes of fossil fuels used and not on percentages. Finally, conclusions are preliminary applied to the European Union policies for net zero by 2050 based on a two-fold strategy: continuing and reinforcing the implementation of the Renewable Energy Directive to 2035, while adopting a new directive for fixed and over time increasing curtailment of fossils as of 2025 until 2050.

The homogeneous branching process with migration and continuous time is considered. We investigated the distribution of the period-life τ, i.e., the length of the time interval between the moment when the process is initiated by a positive number of particles and the moment when there are no individuals in the population for the first time. The probability generating function of the random process, which describes the behavior of the process within the period-life, was obtained. The boundary theorem for the period-life of the subcritical or critical branching process with migration was found.

The Catholic Church

"In less than one year, the Catholic Church, just like the other denominations, lost its school network built along the centuries. This was the moment when the bishop wrote: “No one can resent if we shed tears over the loss of our schools and educational institutions”. Moreover, he stated that he would do everything to re-store the injustice since they could not resent if we used all the legal possibilities and instruments to retrieve our schools that we were illegally dispossessed of. Furthermore, he evaluated the situation realistically and warned the families to be more responsible. He emphasized the parents’ responsibility. First and foremost, the mother was the child’s first teacher of religion. She taught him the first prayers; he heard about God, Jesus, the Virgin Mary, and the angels from his mother for the first time. He asked for the mothers’ and the parents’ support also in mastering the teachings of the faith. Earlier, he already instructed the priests to organize extramu-ral biblical classes for the children and youth. At this point, he asked the families to cooperate effectively, especially to lead an ardent, exemplary religious life, so that the children would grow up in a religious and moral life according to God’s will, learn-ing from the parents’ examples. And just as on many other occasions throughout history, the Catholic Church started building again. It did not build spectacular-looking churches and schools but rather modest catechism halls to bring communities together. These were the places where the priests of the dioceses led by the bishop’s example and assuming all the persecutions, incessantly educated the school children to the love of God and of their brethren, and the children even more zealously attended the catechism classes, ignoring their teachers’ prohibitions.

Technological Imaginary

Technology tends toward perpetual innovation. Technology, enabled by both political and economic structures, propels society forward in a kind of technological evolution. The moment a novel piece of technology is in place, immediately innovations are attempted in a process of unending betterment. Bernard Stiegler suggests that, contra Heidegger, it is not being-toward-death that shapes human perception of time, life, death, and meaning. Rather, it is technological innovation that shapes human perception of time, life, death, and meaning. In fact, for Stiegler, human evolution has always been part of technological evolution. While one can quibble with the notion of human-technology co-evolution, there is something to be said for the way in which human perception of time, of ageing, and of death seems to be judged against the horizon of perpetual evolution of technological innovation. In this technological imaginary, of which modern medicine is constituent, ageing and death seemingly may be infinitely deferred, and it is this innovating deferral that shapes the contemporary social imaginary around ageing and death in modern medicine. Yet, the reality of living (which is to say ageing) and dying always manifests itself differently than the scripts given to us by the technological imaginary with its myth of endless innovation. In fact, I shall argue that, where the Church created an ars moriendi, the technological imaginary gives us an ars ad mortem when it becomes clear that ageing and death cannot be infinitely deferred. And further, I shall argue that the Church must revivify its ars vivendi—that is to say, its liturgies, its arts, its technics—as a counter narrative to the myth of perpetual innovation that shapes the technological imaginary.

Carbon Economy

In response to global climate change, Canada is transitioning towards a low-carbon economy and the need for policy approaches that are effective, equitable, coordinated, and both administratively and politically feasible is high. One point is clear; the transition is intimately tied to the vast supply of ecosystem services in the boreal zone of Canada. This paper describes four contrasting futures for the boreal zone using scenario analysis, which is a transdisciplinary, participatory approach that considers alternative futures and policy implications under conditions of high uncertainty and complexity. The two critical forces shaping the four scenarios are the global economy’s energy and society’s capacity to adapt. The six drivers of change are atmospheric change, the demand for provisioning ecosystem services, the demand for nonprovisioning ecosystem services, demographics, and social values, governance and geopolitics, and industrial innovation and infrastructure. The four scenarios include: (i) the Green Path, where a low-carbon economy is coupled with high adaptive capacity; (ii) the Uphill Climb, where a low-carbon economy is instead coupled with low adaptive capacity; (iii) the Carpool Lane, where society has a strong capacity to adapt but a reliance on fossil fuels; and (iv) the Slippery Slope, where there is both a high-carbon economy and a society with low adaptive capacity. The scenarios illustrate the importance of transitioning to a low-carbon economy and the role of society’s adaptive capacity in doing so. However, they also emphasize themes like social inequality and adverse environmental outcomes arising from the push towards climate change mitigation.

The CO2 that comes from the use of fossil fuels accounts for about 65% of the global greenhouse gas emission, and it plays a critical role in global climate changes. Among the different strategies that have been considered to address the storage and reutilization of CO2, the transformation of CO2 into chemicals and fuels with a high added-value has been considered a winning approach. This transformation is able to reduce the carbon emission and induce a “fuel switching” that exploits renewable energy sources. The aim of this chapter is to categorize different heterogeneous electrocatalysts which are being used for CO2 reduction, based on the desired products of the above mentioned reactions: from formic acid and carbon monoxide to methanol and ethanol and other possible by products. Moreover, a brief description of the kinetic and mechanism of the CO2 reduction reaction) and pathways toward different products have been discussed.

The relevance of the article is determined by the researcher of the semantic poetics of Platonov’s story “Potudan River”. We carry out an analytical review of the lifetime criticism and articles of modern researchers about the story, on the basis of which we formulate the purpose of the study, due to the need for a new approach to the interpretation of the work and the identification of the principles of its poetics. The novelty of the article is determined by the identification of the multilayered symbolism of the title of the story, which allows to establish the insufficiency of the conclusions that the content of the “Potudan River” is limited to the family theme. At the level of micropoetics we reveal symbolic details that connect the content of the story with the motive of love for the distant, medical and construction subjects and revealing the planetary scale of the author’s thinking. For the first time, it was established that Platonov’s story “Potudan River” was written based on part of the plot of the novel “Chevengur” – the love story of Alexander Dvanov and Sonya Mandrova. We show that the heroes of the story “Potudan River” Nikita Firsov, Lyuba Kuznetsova and Nikita’s father are doubles of the characters in the novel “Chevengur” by Sasha Dvanov, Sonya Mandrova, and Zakhar Pavlovich. The connection of the image of Lyuba with the archetype of the bride is considered. The paper reveals for the first time the intertextual connections of the story “Potudan River” with the poem “The Bronze Horseman” and the novel in verse “Eugene Onegin” by A. Pushkin, in the texts of which the writer found material for modeling the ordinary fate of the hero. Multi-level connections of the content of the story “Potudan River” with Platonov’s artistic world, which is a complete metatext, are found, which opens up new opportunities for determining the role of the editing technique and the principles of returning to the plots and motives of the works of the 1920s, as well as their transformation in the writer’s work of the 1930s.
