Sustainability literacy in the Romanian Universities
Authors: Prada Elena-Maria , Apostu Simona-Andreea , Gogu Emilia 
Published: June 2021

Abstract
Sustainable university refers to the active involvement of higher education institutions in elaborating policies to protect the natural environment. The sustainable university is the one that, besides the governmental involvement, contributes to the safety of the environment by adapting the curriculum to the ecological needs and through the progress of the scientific knowledge, as a result of the didactic and research activities.
As a vector of society’s development, the primary role of the university consists of educating future decision-makers. From the point of view of sustainable education, the concept of sustainable literacy has been shaped. Sustainable literacy involves educating future generations for sustainable development, considering the social, environmental, and cultural aspects specific to each country.
In our opinion, “Sustainability literacy” in the academic environment is the formation and transmission of knowledge, skills, values, and attitudes that will allow students/graduates to engage deeply in building a sustainable future and improve their decision-making towards sustainability. The purpose of this research paper is to identify the context of ensuring and promoting sustainability in Romanian tertiary education.
For this purpose, data obtained from the Romanian Agency for Quality Assurance in Higher Education were used regarding the number of students (as an element of the university demand) who follow a study program related to sustainable development, as well as data on the number of study programs in sustainability (as an element of the university offer). The results show that the number of students decreases, mainly due to demographic reasons, and the low graduation rates following the baccalaureate examination. Nevertheless, the number of programs in the sphere of sustainable development was higher in 2018 than the previous year. This fact demonstrates the importance given and the serious concerns regarding sustainability literacy in Romanian universities.
Looking ahead - from fossil fuel to a circular bioeconomy in Europe. Evolution and behaviour
Authors: Zaman Gheorghe , Grădinaru Giani Ionel , Matei Bogdan Florin 
Published: June 2021

Abstract
Giving due consideration to sustainability, the new concept of bioeconomy has faced strong support from international policymakers, changing the way the economy is currently working. And it does not involve only the replacement of fossil feedstock with bio-based fuels, but also acquiring value from waste and bringing to light the resource efficiency that can lead to a smooth transition from a linear to a circular economy. This paper aims to track the EU states movement in implementing the bioeconomy best practices by building clusters based on their progress in adapting their industries to the new requirements. To make this possible, we created two scenarios for recording the evolution of the energy industry in 27 countries: the first one that groups them according to the fossil-fuel sources, and the second one based on renewable resources. Our results revealed that the biomass tends to be used as a complementary source and not a substitute, in comparison to the traditional fuels. Same actors keep the leading positions in both scenarios, making us believe that they may face strong challenges in reaching the European Commission goals. Thus, the present study emphasizes the need to develop highly efficient policies for all EU members to keep the same path.
Working beyond the normal retirement age in urban China and urban Russia
Authors: Gustafsson Björn , Nivorozhkina Ludmila , Wan Haiyuan 
Published: June 2021

Abstract
The incidence of working for earnings beyond the normal pension age of 55 for females and 60 for males in urban China and Russia is investigated using micro-data for 2002, 2013, and 2018. Estimated logit models indicate that, in both countries, the probability of working after normal retirement age is positively related to living with a spouse only, being healthy, and having a higher education level. It is negatively associated with age, the scale of pension, and, in urban China, being female.
We find that seniors in urban Russia are more likely to work for earnings than their counterparts in China. Two possible reasons that are attributable to this difference are ruled out, namely cross-country differences in health status and the age distribution among elderly people. We also demonstrate that working beyond the normal retirement age has a much stronger negative association with earnings in urban China than in urban Russia. This is consistent with the facts that the normal retirement age is strictly enforced in urban China and seniors attempting to work face intensive competition from younger migrant workers. We conclude that China can learn from Russia that it has a substantial potential for increasing employment among healthy people under 70.
Mitigating Long-term Unemployment in Europe
Authors: Miyamoto Hiroaki , Suphaphiphat Nujin 
Published: June 2021

Abstract
While unemployment rates in Europe declined after the global financial crisis until 2018/2019, the incidence of long-term unemployment, the share of people who have been unemployed for >1 year to the total unemployed, remained high. Moreover, the COVID-19 pandemic could aggravate the long-term unemployment. This paper explores the factors associated with long-term unemployment in European countries using a panel of 25 European countries over the period 2000–2018. We find that skill mismatches, labor market matching efficiency, and labor market policies are associated with the incidence of long-term unemployment. Among the different types of active labor market policies, training and startup incentives are found to be effective in reducing long-term unemployment.
The Comparison of Kinship Terminology in the Yulin Dialect and in Cantonese
Authors: Hu Wenmin 
Published: June 2021

Abstract
The Yulin dialect is a sub-dialect of Cantonese, only used in Yuzhou and Fumian districts of the city of Yulin, located in the southeast of Guangxi Zhuang Autonomous Region, China. The kinship terms in Yue dialects include direct and indirect address terms, and usually are a combination of morphemes used to embody referential features (synthetic relation terms) and morphemes that distinguish the degree of kinship (ranking, collateral, spousal, generation and gender terms). This article offers a comparison, in terms of morphology, of kinship terms between the Yulin dialect and Cantonese. It is argued that the Yulin dialect and Cantonese have the same pattern of combining kinship terms, but approximately half of the compared kinship term logograms in the Yulin dialect are totally different from those in Cantonese as used in Canton, and the same terms are used in less than one-fourth of the cases.
How to choose the proper words? The process of vocabulary standardization in Putonghua
Authors: Kurpaska Maria 
Published: June 2021

Abstract
As with most fields of life, China can trace its history of word standardization back to ancient times, when the first dictionaries (such as Erya, ca. 3rd century B.C.) appeared. Modern Standard Chinese used in Mainland China – Putonghua – has been subject to standardization since its proclamation as the official national language of China in 1956. The definition states quite clearly that its base is formed by the Northern dialects. This statement concerns also vocabulary.
However, it is not a simple matter to make a choice of words which are to be used throughout the country. On the one hand, the so-called “Northern dialects” are spoken by almost 70% of the Han Chinese population, i.e. by about 800 million people. Although the Northern dialects are said to be quite uniform, the vast area that they cover must bring diversity in vocabulary. On the other hand, the remaining 30% of the Han Chinese speak a range of mutually unintelligible tongues, which are bound to penetrate the Northern dialects.
The aim of this paper is to show how the lexicon of Putonghua is being codified. An attempt will be made to reveal how the basic vocabulary was selected during the forming of Putonghua in the 1950s. Some of the tools used by the State Language Commission in order to control the process of vocabulary standardization will be described. Moreover, the paper intends to describe the ongoing changes in the Chinese lexicon. It will show the sources of new words that are gradually accepted into the authoritative dictionaries of modern Chinese.
The grammatical distinction between count nouns and mass nouns in Mandarin Chinese
Authors: Stoch Nastazja 
Published: June 2021

AbstractThe purpose of this paper is to prove the Mass Noun Hypothesis wrong. The hypothesis claims that all common nouns in classifier languages like Mandarin Chinese are mass nouns. The objection against it consists in displaying its implausible deduction, where false conclusions have been drawn due to relying on the grammar of English, which is incongruent with the grammar of Chinese. Consequently, this paper defends the Count Noun Thesis, stating that in Chinese there are count as well as mass nouns. In support of this statement, first, the typology of numeral classifiers had to be established, which resulted in gathering and completing all the reasons to distinguish classifiers from measure words. After only this necessary differentiation was made, it was possible to show that the count/mass distinction exists in Mandarin Chinese. That is, count nouns by default have only one classifier, with certain disclaimers. Apart from that, count nouns, as in every language, may undergo some measurement with measure words. Mass nouns, however, in the context of quantification may appear only with measure words, but not with classifiers. These conditions naturally follow from the ontological status of the two types of nouns’ referents, i.e. bounded objects denoted by count nouns, and scattered substances denoted by mass nouns.
Speech shadowing as a teaching technique in the CFL classroom
Authors: Zajdler Ewa 
Published: June 2021

AbstractThe aim of this paper is to present speech shadowing (the listener’s repetition of a word, phrase or sentence immediately after hearing it) as an effective teaching technique. Shadowing has been practiced in English classes in Japan for decades and many studies have confirmed its effectiveness for improving learners’ listening comprehension and pronunciation skills. Even though some studies have already indicated that this technique is successfully used in teaching Chinese as a Foreign Language (CFL) (Zajdler & Chu 2019), its potential has not been widely utilized in the Chinese classroom in Poland. Thus, the present paper will first discuss the auditory and cognitive underpinnings of shadowing, then a classification of the types of shadowing will be proposed. Finally, practical aspects of shadowing as an effective in-class CFL teaching technique will be presented.
Chinese vocabulary and elements of culture reflected in the lexical meaning as a challenge in the teaching of Chinese as a foreign language
Authors: Zhu Zhiping 
Published: June 2021

Abstract
This paper describes the elements of Chinese culture enclosed in vocabulary and in the meaning of words; it is divided into four parts. Firstly, it is pointed out that, due to the fact that words are written down with Chinese characters, teachers of Chinese should purposefully help the students understand the rich culture contained in Chinese words, especially disyllabic compounds. Secondly, the article presents the investigation methods concerning compound words applied by the researchers of Chinese lexicon；It also assesses their applicability with regard to teaching a second language. Thirdly, the paper discusses five ways of incorporating Chinese culture during the process of formation of compound words, and points out their relationship with second language teaching. Finally, the paper discusses the methods applied in teaching Chinese vocabulary, and puts forward two methods of teaching vocabulary and their strategies at different levels.
Biology of the thornback ray (Raja clavataLinnaeus, 1758) in the North Aegean Sea
Authors: Cabbar Koray , Yiğin Cahide Çiğdem 
Published: June 2021

AbstractThe study deals with aspects of the population dynamics in the thornback ray (Raja clavataL., 1758), one of the most abundant cartilaginous fish caught in the North Aegean Sea. Females accounted for 73.08% and males 26.92% of all individuals. Total length of females and males ranged between 50.2 and 89.9 cm (disc width: 33.4–62.0 cm), and between 43.1 cm and 82.7 cm (disc width: 30.7–64.2 cm), respectively. Relationships between total length (TL) and total weight (TW), and between disc width (DW) and total weight (TW) were described by the equations: TW = 0.0041 TL3.10and TW = 0.0178 DW3.03, respectively. Age data derived from vertebrae readings were used to estimate growth parameters using the von Bertalanffy function: L∞= 101.71 cm, K = 0.18 y−1, t0 = −0.07 y for males and L∞= 106.54 cm, K = 0.16 y−1, t0 = −0.28 y for females. The maximum age was 8 years for males and females. Total length at first maturity of males and females was 70.9 cm and 81.2 cm, respectively. Based on the gonadosomatic index and gonadal macroscopic observations, it was determined that the spawning period lasted throughout the year. Stomach content analysis showed that crustaceans (53.03% IRI) and teleosts (14.70% IRI) were the most preferred prey.
Inter-clutch egg differences and androgenesis in rainbow trout (Oncorhynchus mykiss, Walbaum 1792)
Authors: Polonis Marcin , Błaszczyk Agata , Jagiełło Krzysztof , Panasiak Ligia , Dobosz Stefan , Ocalewicz Konrad 
Published: June 2021

Abstract
Ionizing radiation (IR) is applied to inactivate the nuclear genome in rainbow trout eggs during induced androgenetic development. However, IR-generated reactive oxygen species (ROS) may affect developmental potential of eggs and reduce the effectiveness of androgenesis. To verify this assumption, androgenetic development of rainbow trout was induced in eggs irradiated with 350 Gy of X-rays. Survival rates, pH of the ovarian fluid and activity of antioxidant enzymes, including SOD, CAT and GPx, were examined in non-irradiated and irradiated eggs originating from four females. Survival rates of androgenetic embryos developing in eggs produced by different females varied from 1% to 57% and these inter-clutch differences were significant. Eggs from female F4, which showed the highest developmental competence for androgenesis, also showed increased activities of SOD, CAT and GPx enzymes. The pH value of the ovarian fluid of each female was over 8 before and after irradiation, therefore it seems that radiation did not affect the ovarian fluid pH. Considering the above-mentioned inter-clutch differences, a strong maternal effect on the effectiveness of androgenesis can be assumed. Eggs with increased activity of antioxidant enzymes before irradiation should be expected to show increased developmental competence for androgenesis.
The foraminiferal record in the Holocene evolution of the Mecklenburg Bay (south-western Baltic Sea)
Authors: Kostecki Robert , Radziejewska Teresa 
Published: June 2021

Abstract
Foraminiferal assemblages were analyzed in a 620-cm long core retrieved from the central part of the Mecklenburg Bay (MB, south-western Baltic Sea) to aid in the reconstruction of environmental changes occurring in the area during the Holocene and to complement a set of previously investigated palaeoenvironmental proxies. A total of five foraminifera-based stratigraphic units were identified, including an initial 80-cm thick layer devoid of foraminifera. The next two units featured an increasing abundance of the foraminiferal assemblage dominated by the calcareous Ammonia group species. Nearly all the calcareous foraminifera found in the core were decalcified. Following the maximum abundance within the 470–410 cm layer, the foraminiferal abundance declined sharply and the assemblage’s dominance structure changed to domination of the agglutinated foraminiferal species, Eggerelloides scaber, which continued up to the top of the core and marked a pronounced shift in environmental conditions (shallower depth, lower salinity, more dynamic sedimentation conditions). The foraminifera-based stratigraphy of the core proved to be complementary to that emerging from previous analyses of diatoms and sediment geochemistry.
Effects of copper and cadmium on physiology and antifouling defense of the marine macroalga Ulva reticulata

Published: June 2021

Abstract
Heavy metals are major stressors for benthic macroalgal communities in marine ecosystems. In this study, the effects of copper and cadmium on some physiological parameters along with antifouling defense of the marine macroalga Ulva reticulata were assessed under laboratory conditions. Macroalgal samples were treated with three concentrations (1 mg l−1, 3 mg l−1 and 5 mg l−1) of copper and cadmium for 2 and 7 days. After treatment, algal samples were analyzed for chlorophyll-a, carotenoid, total polyphenol and total antioxidant capacity. Also, algal extracts were tested against biofilm-forming bacteria strains to understand differences in antifouling activity. The results indicated that exposure of U. reticulata to copper and cadmium, on the one hand, induced protective mechanisms such as total phenol production and antioxidant capacity against metal stress and, on the other hand, reduced photosynthesis. While the extract obtained from control algal samples showed a strong inhibitory effect on the growth of biofilm-forming bacteria, treatment with heavy metals resulted in reduced antibiofilm activity. In general, the results revealed that exposure of macroalgae to heavy metals can affect antifouling defense traits in addition to changes in photosynthetic pigment content.

Determination of heavy metals in some tissues of four fish species from the Karasu River (Erzincan, Turkey) for public consumption
Authors: Tanır Özge Zencir 
Published: June 2021

Abstract
The study aimed at determining the concentration of heavy metals in muscle, liver, and gill tissues of four fish species (Acanthobrama marmid, Capoeta umbla, Capoeta trutta and Chondrostoma regium) collected from five sites in the Karasu River, Erzincan, between July 2019 and January 2020. The relationships between fish size (length and weight) and metal concentrations in the tissues were also investigated using Pearson correlation analysis. Concentrations of Al, Fe, Cu, Mn and Zn were higher than those of other metals in all tissue samples from four fish species. Fe and Al concentrations were very high, while the lowest Co, Cd and Pb concentrations were determined in the muscle, liver and gill tissues. The results of Pearson correlation analysis showed that significant relationships between heavy metal concentrations and fish size (length and weight) were positive (p < 0.01, p < 0.05), except for a few cases. Furthermore, heavy metal concentrations in the edible parts (muscle) of the studied fish species did not exceed the maximum acceptable concentrations (MACs) proposed by national and international food standards and were safe within human consumption limits, except for Cr.
The Importance of the Sense of Agency in the Process of Social Activity and Participation of Young People
Authors: Myszka-Strychalska Lucyna 
Published: June 2021

SummaryThe social activity of young people is essential for the development of their participation in the social life. It’s conditioned, inter alia, by educational measures directed at stimulating the behaviour of the young people, strengthening their sense of consciousness and responsible influence on the environment. The article presents a deeper insight into the mutual dependence between the individual’s sense of agency (and thus the subject’s belief in his/her ability to influence the reality) and his social activity (understood as the readiness to act for the benefit of others). They are not meaningless for building the social capital of the young generation, which in the near future will be responsible for the fate of the world. One of the analytic categories used to consider the presented issues is the construct of pro-development orientation, the constructive features of which include both trust in others and the world, as well as a sense of agency.
Kindergarten Teachers’Attitudes Toward Distance Education During the COVID-19 Outbreak
Authors: Jankowiak Barbara , Jaskulska Sylwia , Rybińska Anna 
Published: June 2021

Summary
This research report presents results of a study on kindergarten teacher’s attitudes toward distance education during the COVID-19 pandemic and their associations with selected characteristics related to the teacher’s profession. The tools that the teachers used for distance education were also described. 429 correctly completed surveys were collected. The most positive opinions concerned the development of one’s professional competencies, feeling positive emotions in the relationship with children and their parents. One of the worst assessed areas was those related to the possibility of supporting the social and emotional development of children. Most of the examined aspects of professional functioning, e.g. seniority, the location of the kindergarten, did not differentiate the attitudes. The differences mainly concerned teachers of special kindergartens, who in some aspects of attitudes (e.g. positive emotions towards this form of work) obtained lower results than teachers employed in other types of kindergartens.
