Experience of Russian-Chinese industrial cooperation on the construction of the Moscow metro

The commissioning of the Big Circle Line in Moscow, some sections of which were laid jointly with Chinese underground builders, provided the first experience of interaction with foreign construction contractors on the Moscow Metro. The paper investigates this experience which is of value for the development of such works in the future. The analysis was carried out on the basis of scientific and technical documentation on certain facilities, the progress and results of construction and installation works, and information on other events. The paper describes the facilities where construction and installation works were carried out by joint efforts and shows the peculiarities of interaction between Russian and foreign (Chinese) metro builders on a number of sections of the Big Circle Line of the Moscow Metro. The achieved results are demonstrated by the example of individual underground stations. The study reveals the peculiarities of material and technical support of works on the sections constructed by Chinese construction contractors. The mutual exchange of experience, technologies, and work management practices along with the application of various tunnel boring machines from both countries (Russia and the PRC) has yielded fruitful results, demonstrated the possibility and efficiency of the direct engagement of foreign tunnel builders at Russian sites in close cooperation with their Russian counterparts, and revealed a scheme for rational division of labour, work management, and logistical support of works.

Class Management in the Indonesian Language Learning Process for Class V Students at State Primary School 3 Midang Gunungsari West Lombok

Teachers in their role as class managers in learning activities are required to have the abilities and skills so that the expected goals in managing learning activities can be achieved. This is because classroom management in learning activities is an effort made by teachers to create, maintain and develop learning motivation to achieve predetermined goals. Meanwhile, learning itself is the ability to manage operationally and efficiently components related to learning, to produce added value to these components by applicable norms/standards. Classroom management in the learning process which is emphasized in this study is the Indonesian language learning process in Class V of Midang Gunungsari 3 Elementary School, West Lombok with the Big Column (KB) and Big Circle (LB) student seating formations, as well as the obstacles faced by teachers. The results show that when the Indonesian language teacher implements classroom management in the learning process with students sitting in Large Columns (KB) and Large Circles, student learning outcomes average 7.6 grades higher than the Minimum Completeness Criteria (KKM) score for Indonesian Language subjects ( 7.5), while the obstacles faced by teachers when implementing classroom management in the learning process by implementing student seating formations, both Large Columns (KB) and Large Circles (LB), originate from teachers and students, who then seek solutions that originate from teachers. Meanwhile, it came from students, 3 students whose learning results were below the KKM score because they did not concentrate when taking part in the lesson and because they often did not go to school, namely through a special approach both when learning took place in the classroom and outside the classroom.

The Big Circles in Jordan: First absolute ages using rock luminescence surface dating

AbstractIn this study, we provide the first absolute ages for a Big Circle megalithic structure in Jordan, using rock surface luminescence dating of the buried surface of rocks collected from circle J4 in southern Jordan. Five rocks were used for this study. All rocks showed evidence of previous daylight exposure before being used in the construction of the circle. The exposure was sufficient to bleach the latent luminescence signal to a negligible level compared to the subsequent burial dose. Three rocks gave indistinguishable ages, and were last exposed to daylight in 1500 ± 100 BCE; this is very likely to be the date of circle construction. Two others gave younger ages, indicating later disturbance or reworking. These new results provide very strong evidence for construction during the Late Bronze Age, and refute the earlier hypothesis of construction during Umayyad period (661–750 CE) as a hunting trap.

Politeness Strategies Use in the Family Members

Language is essential in social interaction. It is used by society to communicate with others. Besides, language in society is used as a means of communication to express ideas, intentions, opinions, and purposes. In addition, language also has the function of expressing someone’s feelings and emotions. Politeness becomes one of the crucial things to maintain the conversation running well in society. The communication starts from the small circle and then comes to the big circle. The small circle for example in family members is one of the communications that can begin before going to society. Therefore, the present study aimed to analyze the types of politeness strategies used by Rimbi’s family members. This research was categorized as descriptive qualitative research. A descriptive qualitative research design was used to describe the positive politeness in family member conversations. There were 5 members chosen as the subjects in this research. It consisted of a father, a mother, and 3 sisters. The research data were the script of conversation in the form of sentences, clauses, or words. The findings show that the family members rarely use negative politeness despite that bald-off record and off record become the most used strategies use in the family members.

BIBLIOMETRIC ANALYSIS: E-BOOK AND READING COMPREHENSION IN EFL IN THE LAST DECADE

This study examined the analysis of e-books and reading comprehension in EFL in the last ten years. Academics have teaching-learning procedures. In learning one of the skills required in education is reading. Reading is necessary for students' personal and academic development, and reading comprehension is also essential. Reading comprehension is a student's understanding of a text's meaning and value. One learning media that may increase students' reading comprehension in the classroom is the e-book. An E-book is an electronic version of a printed book. The study employs bibliometrics to assess a research trend. This analysis utilizes Scopus information from 2012 to 2022 using PoP, VosViewer examines the metadata, and Tableau Public visualizes the VosViewer findings. This analysis reveals publishing trends, most cited authors and articles, journal rank, publication categories, article pages, nations, and keywords. This study discovered that the map from 29 datasets has 117 terms and 85 items, 13 clusters, and 263 links with 265 link strengths. Some keywords have big circles, such as "English," "Comprehension," "E-book," and "effect," which are the keywords that occur most in the thirteen clusters formed. Each cluster shows a trend with the emergence of numerous keywords that are more distinctive to each cluster. In addition, the keyword "e-book" and "reading comprehension" is also related to the keyword "EFL learners," which is the focus analysis of this study. It shows that keywords are significant research points for e-books and EFL reading comprehension. However, the research has significant drawbacks. The researchers need thus do further investigations.

Blue‐tailed skinks have predation‐dependent threat discrimination

AbstractThe extent to which prey respond to predation risk may depend upon the level of threat it perceives. A prey's perception of a threat can also be influenced by the background levels of predatory threat in the environment. Many animals also rely on visual cues to discriminate threat and assess risk. Eyes, in particular, are known to elicit an aversive response in prey. However, there is a lack of the literature about what salient physical features of a predator's gaze triggers aversion in prey, especially reptilian prey. We capitalized on the putatively aversive effects of eyes to better understand the influence of average background threat on risk perception. We approached blue‐tailed skinks (Emoia impar) with four different treatments: a blank control and three experimental treatments (two circular eyes, two squares, and one big circle) to test whether eye shape or number induced a greater aversive response in prey measured by the time allocated to key activities, as well as by flight initiation distance (FID) in locations of high and low background threat. Skinks discriminated more between treatments at low risk than in high risk situations by varying their behavior in response to treatments only in low‐risk scenarios, but this did not translate into differences in FID. Our results suggest that in high‐risk situations, the cost to discriminate is higher than at low risk. Although we can assume our treatments were not perceived as eyes due to a lack of discrimination toward the two circle treatment, detectability and more specifically diameter of stimuli are the most salient to skinks. While skinks are able to detect subtle differences in visual stimuli, this does not affect their overall fear response. Remarkably, skinks, a species not hunted by humans, have the ability to discriminate subtle features about them, a finding that is seen in other species and requires more study.

'It's just one big vicious circle': young people's experiences of highly visual social media and their mental health.

Highly visual social media (HVSM) platforms, such as Snapchat, Instagram and TikTok, are increasingly popular among young people. It is unclear what motivates young people to engage with these specific highly visual platforms and what impact the inherent features of HVSM have on young people's mental health. Nine semi-structured focus group sessions were conducted with males and females aged 14 and 15 years (n = 47) across five secondary schools in Northern Ireland. Thematic analyses were conducted, and a conceptual model was developed to illustrate the findings. This study found that features such as likes/comments on visuals and scrolling through a feed were associated with the role of 'viewer', instigating longer-lasting feelings of jealousy, inferiority and pressure to be accepted. To combat these negative emotions, young people turn to the role of 'contributor' by using filters, selecting highlights to post to their feed and adjusting their personas, resulting in temporary feelings of higher self-esteem, greater acceptance and popularity. As users of HVSM are constantly switching between the role of viewer and contributor, the emotions they experience are also constantly switching between instant inadequacy and instant gratification. HVSM appears to trigger an unrelenting process of emotional highs and lows for its adolescent users.

Численное моделирование геомеханических процессов при строительстве перегонных тоннелей Московского метрополитена

The largest megalopolis and the main business center of the country, the city of Moscow, is actively expanding from year to year. In this context, the Russian capital is faced with the challenge of developing and expanding its transport infrastructure. According to the 2021 construction plan of the Moscow Metro the total length of the lines will exceed 450 km, and the Big Circle Line will become one of the longest in the world. During the construction of new metro stations specialists face difficult engineering, geological and hydrogeological conditions. Reducing the risks and preventing accidents during underground construction is relying on accounting of all the levels of the excavation and construction works. The article presents a comprehensive analysis of the factors that affect the choice and justification of underground construction technologies. The paper presents the objectives of geomechanical monitoring and measures for geomechanical safety of excavations. Numerical modeling of geomechanical processes during the construction of the running tunnels was made using the Map3D Software. The simulation considered a tunnel of circular cross-section passing through a non-uniform rock mass. The diameter of the cross-section was accepted to be 6 m with the depth of the driving tunnel varying from 15 to 35 m.

Learning Design Cooperative Learning Inside-Outside Circle in Indonesian Language Lessons at Madrasah Ibtidaiyah: A Literature Review

The writing of this article aims to find out the design of the inside-outside circle cooperative learning learning design, namely, 2. The advantage of the Inside Outside Circle technique is that there is a clear structure and allows students to share with different partners briefly and regularly. In addition, students work with fellow students in a cooperative atmosphere and have many opportunities to process information and improve communication skills. The steps for the design of the inside-outside circle cooperative learning technique in Indonesian lessons are that half of the students form a small circle facing out, the other half form a large circle facing in, students facing each other share information simultaneously, students who are in the outer circle rotate then share information with their (new) friends in front of them, and so on.This research method uses the library method by analyzing various books and journals related to the application of the Inside-Outside Circle cooperative learning technique. The conclusions concluded that: 1. learning techniques with the system of inner and outer circles (Inside-Outside Circle) where students share information with each other at the same time with different pairs briefly and regularly.2. The advantage of using the IOC method is that students will easily get different and varied information at the same time. Meanwhile, the steps for implementing the inside-outside circle cooperative learning design in Indonesian lessons are: as follows: 1) The first step, half the class stands in a small circle and faces out. 2) The second step, the other half of the class forms a circle outside the first circle and faces inward. 3) The third step, then two students in pairs from small and large circles share information. This information exchange can be done by all partners at the same time. 4) The fourth step, students in the small circle stay in place, while students in the large circle move one or two steps clockwise, so that each student gets a new partner. 5) The last step, it is the turn of students who are in the big circle to share information. And so on.

Granularity in the Semantics of Comparison

This paper makes the novel observation that definite comparatives, such as the bigger circle, impose restrictions on the cardinality of the comparison class (CC) against which their truth conditions are evaluated. We show that the corpus frequency counts of definite comparatives sharply drop when the comparison class used for their interpretation is formed by more than two individuals. Two alternative theories of these distributional facts are considered and tested experimentally through an acceptability judgment task. According to the first theory, the 2-Individuals Theory, definite comparatives presuppose that the CC is of cardinality 2; under the second theory, the 2-Degrees Theory, the meaning of the comparative is evaluated against a granularity γ that maps the individuals in the CC to degrees in the relevant adjectival scale, and definite comparatives presuppose that the set of the degrees resulting from this mapping is of cardinality 2. Our experimental results show that definite comparative descriptions are most frequent and felicitous when evaluated against comparison classes with two individuals, but also that acceptability drops off with higher cardinalities in a gradient manner that is sensitive to granularity. Taken together, these findings argue against the 2-Individuals theory of definite comparatives and lend support to the 2-Degrees theory.

Over at the College

Today, rural America is complex and layered, and it deserves the attention of those who have spent far too many years flying over it only to occasionally see through the clouds and wonder what those big circles are below dotting the landscape. The manuscripts in this issue chart several ways a spirit of new dialogue with rural America can begin. Authors discuss the embedded qualities of higher education demonstrates well how it is possible to anchor the work of post-secondary education in contemporary rural locations, and other perspectives on that which is possible if we engage productively with rural communities and people. This engagement is long overdue. I don’t believe it is an exaggeration to say the future of our nation depends on healing the divide that has festered entirely too long. Educators have always led the way into the most important work in our society. It is time to boldly approach this work

Nanocomposite based on graphene and intercalated covalent organic frameworks with hydrosulphonyl groups for electrochemical determination of heavy metal ions.

Anelectrochemical sensor constructed by intercalated composites was developed for determination of heavy metal ions. The intercalated composites were composed of hydrosulphonyl functional covalent organic frameworks (COF-SH) and graphene (G). The presence of numerous adsorption sites, such as 18 sulfur atoms and 30 nitrogen atoms per big circle of COFs on COF-SH, was beneficial for the accumulation of heavy metals, while the graphene enhanced the electrical conductivity. The obtained sensor under the optimal conditions successfully detected the presence of heavy metal ions in coastal water samples at concentrations ranging from 1 to 1000μgL-1. The detection limits of Cd (II), Pb (II), Cu (II), and Hg (II) were 0.3, 0.2, 0.2, and 1.1μgL-1, respectively. Furthermore, the sensor still exhibited good stability after multiple uses less than 5%. When it is used in the analysis of actual samples, the recovery of standard addition is higher than 95%. In sum, the combination of hydrosulphonyl functional COFs with graphene looks very promising for the assembly of sensors with high sensitivity toward the determination of heavy metal ions for coastal environmental monitoring.

KVANTIFIKACIJA REZULTATA U DRUŠTVENIM I HUMANISTIČKIM NAUKAMA – CITIRANOST KAO MERILO ISTORIOGRAFSKOG DOSTIGNUĆA U SLUČAJU INSTITUTA ZA SAVREMENU ISTORIJU

Quantifying citations as a measure of academic achievement has been a disputed tool, not only within the Serbian academic community. Nature Magazine published “The Leiden Manifesto”, advocating harmonization between quantitative and qualitative criteria. As a contribution to such efforts, this paper examines the production of the researchers of the Institute for Contemporary History in Belgrade. The Institute has been chosen as the most productive institution in Serbia in terms of the number of publications. Proportionally to the number of published works in a certain language, the most frequently quoted papers have been written in German, then in French. The reason for that is the particular interest of some big academic communities for certain issues. For example, the German academic community’s curiosity for socialism derives from its interest in the German Democratic Republic, its history and its society. Papers dealing with foreign workers also address some German internal issues. Publications in French have been more often quoted if they addressed World War I topics. And last but not least, works on the Yugoslav wars of the 1990’s reflects the political and academic interest of the international community. Thus, the most quoted works often respond to the requirements of some foreign factors, such as the international community or some big national academic circles (German and French). These papers sometimes fail to address certain local educational and cultural needs. It is important to combine broader regional and international interests with internal cultural needs. Therefore, more papers should be written in foreign languages, especially in English, which is the primary language of international academic exchange.

Determiners are "conservative" because their meanings are not relations: evidence from verification

Quantificational determiners have meanings that are "conservative" in the following sense: in sentences, repeating a determiner's internal argument within its external argument is logically insignificant. Using a verification task to probe which sets (or properties) of entities are represented when participants evaluate sentences, we test the predictions of three potential explanations for the cross-linguistic yet substantive conservativity constraint. According to "lexical restriction" views, words like every express relations that are exhibited by pairs of sets, but only some of these relations can be expressed with determiners. An "interface filtering" view retains the relational conception of determiner meanings, while replacing appeal to lexical filters (on relations of the relevant type) with special rules for interpreting the combination of a quantificational expression (Det NP) with its syntactic context and a ban on meanings that lead to triviality. The contrasting idea of "ordered predication" is that determiners don't express genuine relations. Instead, the second argument provides the scope of a monadic quantifier, while the first argument selects the domain for that quantifier: the sequences with respect to which it is evaluated. On this view, a determiner's two arguments each have a different logical status, suggesting that they might have a different psychological status as well. We find evidence that this is the case: When evaluating sentences like every big circle is blue, participants mentally group the things specified by the determiner's first argument (e.g., the big circles) but not the things specified by the second argument (e.g., the blue things) or the intersection of both (e.g., the big blue circles). These results suggest that the phenomenon of conservativity is due to ordered predication.

The suburban forest as a habitat of eagles (Accipitridae): a case study in Gunung Bromo University Forest, Karanganyar, Central Java, Indonesia

Eagles (Accipitridae) are sensitive to environmental disturbance such as fragmented environment. This study was aimed to describe the forest in Gunung Bromo as a habitat of the eagles. The research method used was the case study, habitat observation, monitoring presence of eagles, and literature review. Gunung Bromo University Forest is totally fragmented suburban forest with four types of habitat such as oligoculture forest, mixed forest, cropland and riverstream. Two species of eagles were found in the area namely Nisaetus cirrhatus and Spilornis cheela. Potential prey for the eagles found in the area was six species of snakes, eight species of amphibians, five species of lizards, 32 species of birds, and three species of small mammals. Inactive eagle’s nest was also found, and the shape of nest is a big circle with neat plaits created from branches placed in the upper canopy of Bombax ceiba tree. The nest presumed to be used by N. cirrhatus. The study also noted the competitor namely Artamus leucorynchus which often aggressively mobbing the eagles when soaring. Gunung Bromo University Forest was a good habitat for eagles, although it was fragmented. It provided four different habitats, diverse preys, and nesting site. Threats for conservation of eagles in the forest were illegal hunter and noise from visitors’ motocross.

Effect of arc cracks in composite rock strata on ground vibration under SH wave

The existence of cracks complicates the scattering wave field in composite rock strata. The cracks not only affect the dynamic features of the site but also influence the displacement amplitude of the ground vibration. Therefore, it is of engineering significance to study the crack scattering in composite rock strata. Based on the function of complex variables (CVF) and big circle method, this paper constructs a series solution to the scattering wave field of the arc crack in composite rock strata. Specifically, a series of equations were established according to the continuous conditions of stress and displacement at the boundaries of the rock layer and the crack. Then, the model was solved by Fourier series and truncating finite terms, followed by the discussion of the calculation error. Through programming calculations, the authors analyzed the impact of two arc cracks in the “upper-hard and lower-soft” composite rock strata on the ground vibration under incident SH wave. The results show that the magnitude of ground displacement depends on the following factors: the medium parameters of the rock layer, the frequency of the incident wave, and the depth and direction of the cracks; compared with the lower rock layer, the surface rock layer can obviously amplify the amplitude of the ground displacement; with the growing frequency of the incident wave, the influence of horizontal and vertical cracks on the amplitude of the ground displacement first increased and then decreased; the shallower the crack, the greater the impact on ground displacement amplitude; the horizontal crack had a greater influence on the ground displacement amplitude than the vertical crack.
