Aim. The aim of the article is to understand how Chinese parents draw on their learning beliefs and experiences within the Chinese educational context to make decisions about their children’s overseas education, as well as analysing how their learning beliefs are similar or different from East Asian or Western learning beliefs. Methods. The study is based on more than 100 in-depth separate interviews with 22 Chinese families conducted over serval years between 2016 and 2019. Based on interpretative phenomenological analysis and discourse analysis, the results are coded according to the theory of values proposed by Clyde Kluckhohn (1951). These learning values are further coded according to whether they are reflective of the American learning model (EALM), Confucian learning model (CLM), and Confucian learning philosophies. Results. The analysis shows that Chinese parents have displayed similar learning beliefs in socialising their children in the family domain, in their disapproval of the Chinese education system, and in their pursuit of a Western overseas education. The Chinese families’ pursuit of a Western education for their children are driven by their cultural leaning beliefs, which are rooted in Confucian heritage culture, and which also echo European American heritage cultures. Conclusion. Many researchers tend to emphasise cultural differences in learning, particularly between Confucian heritage and European American heritage cultures. This paper shows the possibilities of cultural learning values shaping educational choices, expands upon the understanding of Confucian heritage culture, and suggests the similarities between the learning cultures of East Asia and the West.

Opis:
Among the five religions (zōngjiào) whose followers operate in eight legal organizations in the Peo-ple’s Republic of China, there is no Confucianism (rújiā). Interestingly, for over half a century, researchers of this tradition have been engaged in a lively, serious discussion about the possibility of recognizing it as a religion. At the beginning of the article, the difficulties associated with this issue are mentioned. Then, by way of introduction, Confucius’s religiosity as illustrated in the Analects is discussed. The main part presents several rele-vant approaches to Confucianism that emphasize, although for different reasons, its religious character. They are accompanied by various references to the phenomenon of religion, which constitute their context, as well as reservations expressed towards these approaches. Additionally, the text contains comments on Chinese spiritu-ality, which are important in relation to attempts to resolve the discussed issue.

Opis:
We determine the beginning of the Neolithic farming in northern Egypt, based on analysis of core FA-1 of lake deposits in the Faiyum Oasis in northern Egypt. Regular lamination of the early Middle Holocene lake deposits, supported by radiocarbon dating and pollen analysis, indicates the earliest occurrence of domesticated cereals at ~7.8 cal ka BP in this region. The appearance of cereals in the Faiyum region was possible due to fundamental restructuring of regional climatic conditions caused by the changing atmospheric circulation in the eastern Mediterranean region. Stronger northwestern winds were accompanied by increased precipitation in winter and enabled 3 farming phases in the Faiyum Oasis at 7.8–7.6, 7.4–7.2 and 7.0–6.8 cal ka BP, separated by arid episodes with predominant southern winds. Most probably, cereal cultivation concentrated inside local wadis to the north of the lake and was rainfall-dependent. Therefore, early Egyptian farming did not develop based on irrigation systems as commonly thought, but was rain-fed, this being possible due to marked climate change at the beginning of the Middle Holocene.

Opis:
The article presents the results of monitoring the aftereffect of the use of excessive zonal doses of mineral fertilisers on soil contamination with heavy metals (HM). With traditional soybean cultivation technology, the level of soil contamination when applying excessive doses (N60 P180 K90) of fertilisers is quite high and indicates violations of the ecological balance of the agroecosystem. By the nature of the accumulation of heavy metals in meadow-chestnut soil, depending on the application of the studied doses (P60 K30, N30 P60 K30, N60 P180K90) of fertiliser, the content of HM (Pb, Zn, Cd) increases. The greatest contamination of the soil with Cu was revealed, the content of which increases to 3.2 mg∙kg-1 of soil, which is higher than the threshold of the maximum permissible concentration (MPC) - 3.0 mg∙kg-1. According to the level of contamination of the soil with copper, it belongs to the highly dangerous classes. In a comparative assessment of the level of soil contamination with HM, optimal norms of mineral fertilisers have been established, namely, against the background of effective resource-saving technology for growing soybeans. The application of fertilisers at a dose of P60 K30 and N30 P60 K30 does not significantly affect the level of soil contamination with HM, optimises the ecological state and nutrient regime of the soil, preserves and restores soil fertility indicators, and increases soybean productivity. This resource-saving technology provides a safe environment for soybean cultivation and a significant increase of 34.5-38.6% in crop productivity (0.53-0.76 Mg∙ha-1) and yield (2.57 Mg∙ha-1).

Opis:
Przedmiotem artykułu jest oparta na estetycznej idei samodoskonalenia (niem. Bildung) koncepcja polityczna przedstawiciela preromantyzmu niemieckiego Wilhelma von Humboldta. Autor zwraca uwagę, że charakterystyczna dla preromantyzmu i romantyzmu niemieckiego koncepcja estetyczna wprowadziła nowy paradygmat w zakresie postrzegania twórczości artystycznej. Klasyczna wizja sztuki jako naśladownictwa za sprawą zradykalizowanej przez preromantyków i romantyków niemieckich Kantowskiej filozofii podmiotu została przeformułowana w filozofię kreacji artystycznej pojmowanej jako ekspresja indywidualności i oryginalności artysty. Na tym nowym estetyczno-indywidualistycznym paradygmacie Wilhelm von Humboldt oparł swoją klasycznie liberalną wizję państwa minimalnego. Estetyczna koncepcja Bildung stała się w ten sposób fundamentem filozofii politycznej.
The article examines the esthetic conception of self-cultivation (Bildung), which is the key idea of the political thought of Wilhelm von Humboldt, one of the most important representatives of German idealism and pre-Romanticism. Conceptions of pre-Romanticism and Romanticism have brought new, revolutionary paradigm of an artistic activity. Unlike the classical concepts (e.g. Plato), which generally saw art as an imitation of nature, the pre-Romantic and Romantic conceptions have started to interpret art primarily as an expression of an artist’s originality and individuality. The starting point for this change of esthetic paradigm was surprisingly the Kantian philosophy of the subject, interpreted in a radical manner by German pre-Romantics and Romantics. In Humboldt’s thought, the new, esthetic and individualist paradigm creates foundations for the classical, liberal conception of the minimal state. Therefore, the esthetic conception of self-cultivation became the very foundation of Humboldt’s political philosophy.

Opis:
Nasilające się coraz bardziej zmiany środowiskowe i postępujący kryzys klimatyczny zmuszają do ciągłego poszukiwania przyczyn tego problemu. Upatrywany jest on nie tylko w postępie technicznym, industrializacji i konsumpcjonizmie, ale w negatywnym podejściu człowieka do natury. Jednym z jego rozwiązań jest kształtowanie nowej postawy proekologicznej, która funkcjonuje nie tylko w wymiarze przyrodniczym, ale też społecznym i kulturowym. Przejawem współczesnej myśli ekologicznej są ogrody, które zyskały obecnie status ponadczasowego ekologicznego toposu i stają się ekosymbolem relacji człowieka ze środowiskiem. W tym rozumieniu ogrody są miejscem współżycia człowieka z naturą, która jest traktowana jako wspólny dom — oikos. Celem niniejszego artykułu jest wyjaśnienie współczesnej idei ogrodów ekologicznych oraz próba odnalezienia ich genezy w rzymskiej literaturze agronomicznej oraz ogrodach średniowiecznych. Ponadto odniesienie ówczesnych praktyk i rozwiązań ogrodowych do współczesnego znaczenia ekologicznego.
The increasing environmental changes and the progressive climate crisis are forcing a constant search for the causes of the problem. It is seen not only in technological progress, industrialization and consumptionism, but in man’s negative attitudes towards nature. One of its solutions is the formation of a new pro-ecological attitude, which operates not only in the natural, but also in the social and cultural context. A manifestation of contemporary ecological thought are gardens, which have now acquired the status of a timeless ecological topos and are becoming an ecosymbol of man's relationship with the environment. In this sense, gardens are a place of coexistence between man and nature, which is treated as a common home — an oikos. The purpose of this article is to explain the contemporary idea of ecological gardens and to try to trace their origins in Roman agronomic literature and medieval gardens. In addition, to relate the garden practices and solutions of the time to the modern ecological meaning.

Opis:
Pyrophoric iron sulfides formed as a result of oil cracking, when in contact with air oxygen, have the ability to self-ignite, as a result of which they are highly explosive at oil refining enterprises. It is known that the oil refineries in Kazakhstan produce from 4 to 10 tons per year of this hazardous waste. The main idea of the study was to use the biochemical abilities of microorganisms, in particular the thionic bacteria Acidithiobacillus ferrooxidans, to change the physico-chemical properties of pyrophoric iron sulfides. In this regard, the aim of the study was to determine the possibility of using A. ferrooxidans for deactivation of pyrophoric iron sulfides at an oil refinery in the south of Kazakhstan. It was found that the cultivation of a strain of thionic bacteria A. ferrooxidans ThIO1 in solutions with pyrophoric iron sulfides as the only source of divalent iron and compliance with optimal conditions for their vital activity: +28 °C, pH 2.0–2.5, S:L=1:10±2, will decontaminate explosive waste of oil and gas industry enterprises. The method of biological decontamination of pyrophoric iron sulfides was introduced at the PetroKazakhstan Oil Products LLP refinery in Southern Kazakhstan in 2007. For the successful implementation of this method at other enterprises, it is necessary to develop a special adapted industrial installation for the biological decontamination of pyrophoric deposits with continuous (in the case of receiving waste from different enterprises of Kazakhstan) or periodic cultivation of microorganisms, and compliance with optimal parameters for the vital activity of microorganisms.

Opis:
Historians have relied for too long on written sources (the letters that Pope Martin I wrote from Cherson, as well as De Administrando Imperio) to assess the economic situation in the Crimea, especially in Cherson, during the so-called Dark Ages (7th to 9th centuries). Many still believe that that city could not have survived without shipments of grain from the outside, particularly from the lands along the southern coast of the Black Sea. Seals of Byzantine officials found in Cherson tell a different story, as they indicate commercial exchanges between the Crimea and Constantinople. If the peninsula participated in trade, something must have been offered in exchange for the goods coming from the Capital. The archaeological evidence strongly suggests that during the 8th and 9th centuries, the hinterland of Cherson, as well as the Kerch Peninsula (eastern Crimea) witnessed rapid economic development, largely based on the cultivation of crops. Silos found on several settlement sites, both open and fortified, suggest a surplus, which was most likely commercialized. If so, the closest markets were across the Black Sea, to the south, primarily in Constantinople. Other commodities, such as wine transported in amphorae, traveled in the opposite direction, across the Sea of Azov and into the interior of Khazaria. In exchange, the peninsula received shipments of grain, which were then re-exported to Constantinople. Far from relying on shipments of grain from the Capital, Cherson and the rest of the Crimean Peninsula in fact supplied Constantinople with food. Numerous vats for the production of fish sauce have been found in Cherson, and many were in operation before 900. A good deal of the garum served at tables in Constantinople between the 7th and the 9th century must have come from Cherson. The archaeological evidence therefore calls for a re-assessment of the economic situation in the Crimean Peninsula during the “Dark Ages”.

Opis:
In recent years, infections are more often caused by pathogens with high multi-drug resistance, classified as the “ESKAPE” microorganisms. Therefore, investigation of these pathogens, e.g., Klebsiella pneumoniae, often requires biomass production for treatment testing such as antibiotics or bacteriophages. Moreover, K. pneumoniae can be successfully applied as a biocatalyst for other industrial applications, increasing the need for this bacteria biomass. In the current study, we proposed a novel magnetically assisted bioreactor for the cultivation of K. pneumoniae cells in the presence of an external alternating magnetic field (AMF). High efficiency of the production requires optimal bacteria growth conditions, e.g., temperature and field frequency. Therefore, we performed an optimization procedure using a central composite design for these two parameters in a wide range. As an objective function, we utilized a novel, previously described growth factor that considers both biomass and bacteria growth kinetics. Thus, based on the response surface, we could specify the optimal growth conditions. Moreover, we analysed the impact of the AMF on bacteria proliferation, which indicated positive field frequency windows, where the highest stimulatory effect of AMF on bacteria proliferation occurred. Obtained results proved that the magnetically assisted bioreactor could be successfully employed for K. pneumoniae cultivation.

Opis:
Mencius, referred to as second sage in Chinese philosophy history, grounds his theory about original goodness of human nature on psychological components by bringing in something new down ancient ages. Including the principles of virtuous action associated with Confucius to his doctrine, but by composing them along psychosocial development, he theorizes utterly out of the ordinary that makes all the difference to the school. In his argument stated a positive opinion, he explains the method of forming individuals’ moral awareness by means of inseparable integrity of feelings and thoughts, saying human being are born innately good. According to Mencius, heart-mind correlation is the motivational complement of inner incentives. Knowledge and virtue, which are extensions of inborn goodness, comprehended intuitively; then affective motives respond to circumstance, what is learned transmits to cognitive process and eventually behavior emerges. Comparing during the years of Warring State period he lived, in western geography Aristotle, who is one of the pioneers of Greek philosophy, argues deductive and inductive methods in mental activity. On the other hand, Mencius uses analogical reasoning throughout his self-titled work. This essay is an attempt to assert that most postulates of developmental theories, which have been considered an integral part of modern psychology, begin with Mencius in early era. Secondly, this study also aims to discuss the main paradigm of Mencius across emotivist-rationalist opposition, which keeps emotion above thought as well as reason above emotion.

Opis:
This review presents a recent review of knowledge on the possibilities of sorghum cultivation in Poland including the strategies for its utilisation. Sorghum is the fifth cereal in the world in terms of production scale. This position stems from high tolerance of this plant to water shortages and, at the same time, relatively good yields. Therefore, the main sorghum growing re- gions are concentrated in Africa and Asia. In Europe, due to the sufficient supply of consumer and fodder grains of the main cere- als (wheat, triticale, rye, oats, and barley), there has been a lack of interest from growers in sorghum cultivation. The plant also has high temperature requirements during the emergence period and requires a long growing season, hence food products from sorghum came from imported grains. Although in Poland the plant still has a small cultivated area, there are visible attempts by growers to cultivate sorghum. The grains can be used more widely in human nutrition, especially for people with gluten in- tolerance. It is used in livestock feed production. It can be used in the production of bioethanol. In addition to grain production, sorghum can also be grown for green matter, which has applica- tions in ruminant nutrition (cattle, sheep and goats) and biogas production. The aim of this study is to analyse the potential of sorghum cultivation in Poland and the possible directions of cul- tivation (for grain and green matter) and use (for human food, animal feed and energy purposes). The analysis of the world and Polish literature in the field of sorghum cultivation shows that this species can be cultivated and widely used in Poland. However, it is necessary to popularize the nutritional value and food use of grain in order to build a market. The forage use of both grain and green sorghum mass should also be popularized. The possibility of cultivating sorghum for energy purposes is also a future trend.
