Student participation in a coastal water quality citizen science project and its contribution to the conceptual and procedural learning of chemistry
Authors: Araújo J. L. , Morais C. , Paiva J. C.
Published: September 2021

The active participation of citizens in scientific research, through citizen science, has been proven successful. However, knowledge on the potential of citizen science within formal chemistry learning, at the conceptual and procedural levels, remains insufficiently explored. We developed a citizen science project – PVC: Perceiving the Value of Chemistry behind water and microplastics – which sought to involve students in monitoring the physicochemical parameters of coastal water quality, through the detection of microplastics in these waters, in addition to the qualitative identification of plastic contaminants on beaches. The project was conducted throughout the 2018/2019 school year and involved 442 middle school students (Key Stage 3 (KS3) aged 12–14, in Portuguese schools) and 9 chemistry teachers, in the northern coastal region of Portugal. The data on learning outcomes was collected through knowledge tests, applied after project conclusion, and was then compared to data collected up to six months later (retention test). In addition, interviews were conducted with participants, and researchers’ field notes were recorded and analyzed. Data analysis suggests the PVC project promoted conceptual chemistry learning related to the analysis of physicochemical water parameters (pH, temperature, turbidity, salinity, nitrate and nitrite concentrations and dissolved oxygen), as well as polymers (polymer types, formation and structure). A positive knowledge retention was registered a few months after the project conclusion. At a process level, participants learned laboratory techniques (sieving, gravity and reduced pressure filtrations and crystallization) and the handling of laboratory materials. Furthermore, teachers recognized that their students’ participation in the PVC project fostered the development of their argumentation skills, as well as their reflexive and critical thinking skills. The ability to communicate ideas and results, along with the development of students’ digital skills, was also mentioned.

Conventional protein kinase C in the brain: repurposing cancer drugs for neurodegenerative treatment?
Authors: Lordén Gema , Newton Alexandra C.
Published: September 2021

Protein Kinase C (PKC) isozymes are tightly regulated kinases that transduce a myriad of signals from receptor-mediated hydrolysis of membrane phospholipids. They play an important role in brain physiology, and dysregulation of PKC activity is associated with neurodegeneration. Gain-of-function mutations in PKCα are associated with Alzheimer’s disease (AD) and mutations in PKCγ cause spinocerebellar ataxia (SCA) type 14 (SCA14). This article presents an overview of the role of the conventional PKCα and PKCγ in neurodegeneration and proposes repurposing PKC inhibitors, which failed in clinical trials for cancer, for the treatment of neurodegenerative diseases.
Data‐driven optimal PEMFC temperature control via curriculum guidance strategy‐based large‐scale deep reinforcement learning
Authors: Li Jiawen , Yang Shengchun , Yu Tao , Zhang Xiaoshun
Published: September 2021

As the proton exchange membrane fuel cell (PEMFC) is a nonlinear, time‐varying, multiple‐input multiple‐output system, an advanced controller with strong robustness and adaptability is required for controlling PEMFC stack temperature and achieve a high operation efficiency. In this paper, a data driven optimal controller is proposed for controlling the stack temperature, which is based on large‐scale deep reinforcement learning. In addition, a new deep reinforcement learning algorithm termed curriculum guidance strategy large‐scale dual‐delay deep deterministic policy gradient (CGS‐L4DPG) algorithm is proposed for this controller. The design of this algorithm introduces the concepts of the curriculum guidance strategy and imitation learning, and its inclusion improves the performance and robustness of the proposed controller. The simulation results show that, taking advantage of the high adaptability and robustness of CGS‐L4DPG algorithm, the proposed controller can more effectively control the PEMFC stack temperature than existing control algorithms.

We analyze two high-resolution spectral transit time series of the hot Jupiter HAT-P-32 b obtained with the CARMENES spectrograph. Our new XMM-Newton X-ray observations of the system show that the fast-rotating F-type host star exhibits a high X-ray luminosity of 2.3 × 1029 erg s−1 (5–100 Å), corresponding to a flux of 6.9 × 104 erg cm−2 s−1 at the planetary orbit, which results in an energy-limited escape estimate of about 1013 g s−1 for the planetary mass-loss rate. The spectral time series show significant, time-dependent absorption in the Hα and He Iλ10833 triplet lines with maximum depths of about 3.3% and 5.3%. The mid-transit absorption signals in the Hα and He Iλ10833 lines are consistent with results from one-dimensional hydrodynamic modeling, which also yields mass-loss rates on the order of 1013 g s−1. We observe an early ingress of a redshifted component of the transmission signal, which extends into a redshifted absorption component, persisting until about the middle of the optical transit. While a super-rotating wind can explain redshifted ingress absorption, we find that an up-orbit stream, transporting planetary mass in the direction of the star, also provides a plausible explanation for the pre-transit signal. This makes HAT-P-32 a benchmark system for exploring atmospheric dynamics via transmission spectroscopy.
Breaking the millikelvin barrier in nanoelectronics

Published: September 2021

In labs across Europe physicists are pushing the boundaries of how far we can cool the electrons in nano-fabricated circuits and quantum-enhanced devices. The cryogen-free revolution in dilution refrigeration has liberated researchers from a reliance on helium, a costly and non-renewable resource, and hugely expanded the numbers of cooling machines available for new science and quantum technology applications which exploit the properties of materials at kelvin and millikelvin temperatures.
The mercury removal mechanism of selenium mercury material by soda roasting
Authors: Zhu Shan , Yang Na , Zhang Lin
Published: September 2021

In the present work, Scanning Electron Microscope (SEM) and Energy Dispersive X-ray Spectroscopy (EDS) were employed in the investigation of roasting mechanism, roasting dynamic model, control step of soda roasting process of selenium–mercury material. The results indicated that at the beginning of the roasting process, the control step might be interface chemical reaction for the first 30 min, and the kinetic equation might be 1−(1−R)⅓ = Kt with a activation energy E1 = 40.50 kT/mol. However, as the roasting proceeded, internal diffusion gradually became the control step for 90–135 min, and the kinetic equation might be 1−⅔R−(1−R)⅔ = Dt with a activation energy E2 = 6.75 kT/mol. The SEM analysis of the roasted selenium–mercury materials indicated that the dynamic model of soda roasting attributed to the shrinkage model was reasonable. Combined with the results obtained by SEM and EDS of the roasted selenium–mercury materials, we concluded that the addition of too much Na2CO3 might lead to the formation of molten crystalline phase in the inner of the roasted selenium–mercury materials, changing the mercury removal mechanism of the roasting process. Meanwhile, Se had a tendency to segregate at where the content of Na was relatively high. In order to study the mechanism of diffusion, Na2O2 of 9% was added to one of the samples. According to the results, we concluded that the diffusion of products (such as HgxOy) from the inside of the raw material was the control step of internal diffusion.
Cost-sharing strategy for recycling and service investment in a closed-loop supply chain
Authors: Shan Renbang , Luo Li , Kou Ran
Published: September 2021

This paper investigates the cost-sharing strategies of a manufacturer, a retailer and a third-party recycler in a Stackelberg game considering government subsidy and retailer’s service effort. Next, we construct profit functions of the manufacturer, the retailer and the third-party recycler considering government subsidy and service effort for four scenarios: no cost-sharing (N), service investment cost-sharing (I), recycling investment cost-sharing (II), and both service and recycling investment cost-sharing (III). Furthermore, we obtain the optimal results and discuss the impact of cost-sharing ratio, service cost coefficient, government subsidy and service sensitivity coefficient on profits and social net benefits. The results show that the service investment cost-sharing strategy cannot achieve profit coordination, and under certain conditions, the recycling investment cost-sharing strategy and the service and recycling investment cost-sharing strategy can achieve profit coordination. In addition, changes in different factors such as government subsidy, service cost coefficients, and service sensitivity coefficients will affect the effectiveness of cost-sharing strategies.
Designing a bi-objective decision support model for the disaster management
Authors: Nayeri Sina , Asadi-Gangraj Ebrahim , Emami Saeed , Rezaeian Javad
Published: September 2021

This paper addresses the allocation and scheduling of the relief teams as one of the main issues in the response phase of the disaster management. In this study, a bi-objective mixed-integer programming (BOMIP) model is proposed to assign and schedule the relief teams in the disasters. The first objective function aims to minimize the sum of weighted completion times of the incidents. The second objective function also minimizes the sum of weighted tardiness of the relief operations. In order to be more similar to the real world, time windows for the incidents and damaged routes are considered in this research. Furthermore, the actual relief time of an incident by the relief team is calculated according to the position of the corresponding relief team and the fatigue effect. Due to NP-hardness of the considered problem, the proposed model cannot present the Pareto solution in a reasonable time. Thus, NSGA-II and PSO algorithms are applied to solve the problem. Furthermore, the obtained results of the proposed algorithms are compared with respect to different performance metrics in large-size test problems. Finally, the sensitivity analysis and the managerial suggestions are provided to investigate the impact of some parameters on the Pareto frontier.
A beam search for the equality generalized symmetric traveling salesman problem
Authors: Ben Nejma Ibtissem , M’Hallah Rym
Published: September 2021

This paper studies the equality generalized symmetric traveling salesman problem (EGSTSP). A salesman has to visit a predefined set of countries. S/he must determine exactly one city (of a subset of cities) to visit in each country and the sequence of the countries such that s/he minimizes the overall travel cost. From an academic perspective, EGSTSP is very important. It is NP-hard. Its relaxed version TSP is itself NP-hard, and no exact technique solves large difficult instances. From a logistic perspective, EGSTSP has a broad range of applications that vary from sea, air, and train shipping to emergency relief to elections and polling to airlines’ scheduling to urban transportation. During the COVID-19 pandemic, the roll-out of vaccines further emphasizes the importance of this problem. Pharmaceutical firms are challenged not only by a viable production schedule but also by a flawless distribution plan especially that some of these vaccines must be stored at extremely low temperatures. This paper proposes an approximate tree-based search technique for EGSTSP . It uses a beam search with low and high level hybridization. The low-level hybridization applies a swap based local search to each partial solution of a node of a tree whereas the high-level hybridization applies 2-Opt, 3-Opt or Lin-Kernighan to the incumbent. Empirical results provide computational evidence that the proposed approach solves large instances with 89 countries and 442 cities in few seconds while matching the best known cost of 8 out of 36 instances and being less than 1.78% away from the best known solution for 27 instances.
What competences make translation teachers happy?
Authors: Sdobnikov Vadim V.
Published: September 2021

The study is conditioned by the lack of systematic training for translation teachers both in Russia and in foreign countries. To improve the quality of preparing translators, it is necessary to determine the basic principles of training those who teach them, i.e. translation teachers. The study aims at describing a set of competences that a translation teacher should have. To attain this end, the authors used the following methods: a literature overview on the training of translation teachers; the analysis of prominent works containing theoretical provisions that contribute to the development of basic principles for training translation teachers; a questionnaire survey of translation teachers in the Russian universities. The survey has demonstrated that about half of translation teachers have a special degree in translation, while the other half have only a philological degree. Teachers of both categories have not mastered translation didactics. Philology teachers often do not have sufficient translation experience and have a poor command of translation theory. Thus, modern translation teachers do not have a special set of competences that would allow them to effectively train future translators. As a result, a model of the competences of a translation teacher was proposed, including three blocks: professional translation competences, general and special didactic competences. Thus, the scientific novelty of the research lies in the formulation of strict requirements for the training of translation teachers.
Representation of emotion in English syntax and teaching Russian EFL students
Authors: Rakhmankulova Svetlana Evgenyevna , Sineokova Tatiana Nikolaevna , Kokhan Nadezhda Alexandrovna , Kuzmin Robert Alexeyevich
Published: September 2021

The article looks into English simple utterances about a person’s emotional state. The authors dwell on the ways the English simple sentence patterns are employed in utterances about emotional states and reveal the types of sentence patterns and types of propositions (event schemas) structuring emotional states. The authors also discuss the factors that determine the way a particular emotional event is conceptualized and structured and describe the mechanisms underlying the representation of emotional states in syntax and the choice of a sentence pattern for an utterance about this event. Special attention is given to the mechanism of conceptual metaphor that manifests itself in sentence patterns. The paper lists types of propositional schemas mapped onto concepts of emotional experiences and singles out regular correspondences between the source domain and the target-domain in these metaphorical mappings. The authors also tackle the issue of applying knowledge of sentence representation of emotional states in teaching Russian EFL students to use English syntax correctly and authentically. Teaching syntax in the proposed approach is aimed at helping students to assimilate propositional schemas of the English sentence as models of structuring reality with their metaphoric extensions and then to develop skills of employing these schemas in speaking.
Syntactic means of positive emotions representation in American and British drama
Authors: Sineokova Tatiana Nikolaevna , Rakhmankulova Svetlana Evgenyevna , Belyaeva Ekaterina Ivanovna
Published: September 2021

The paper discusses the peculiarities of syntactic constructions presenting positive emotions in the speech of characters in dramas by modern American and British playwrights. The proposed research method suggests application of a correlative classification of extralinguistic and linguistic features including paradigmatic systems of emotional states and structural forms as an instrument for qualitative and quantitative analysis. Positive emotions are classified according to the criterion of their impact on speech-thought processes. A hierarchical paradigmatic classification of structural deformations of the emotionally neutral invariant including transformations, modifications and primary syntactic features is introduced. The prognostic potential of primary syntactic features in respect of the three types of emotional states is explored. It is shown that more than a half of primary features when used in isolation belong to the first (absolute) or the second level of dominancy according to the algorithmic identification of the emotional state type and that the character of positive emotions’ effect on the speech-thought process (beneficial, boundary or destructive) correlates with the choice of syntactic structures. Differences in the number and types of syntactic constructions realized under the influence of positive and negative emotions are described. The role of qualitative and quantitative discrepancy in syntactic specificities with positive and negative emotions for further researches concerning identification issues purposes is shown.
Four centuries of German “happiness” in lexicographers’ interpretations
Authors: Ivanov Andrey Vladimirovich , Ivanova Rimma Anvarovna
Published: September 2021

The article deals with the concept of “happiness”, represented and interpreted through lexicography. The objective of the study is to try to compare the perspectives of researchers on the origin of the word Glück, trace the development of its semantics from one generalized meaning to a set of meanings reflecting the evolution of human ideas about happiness, and identify ways of representing these ideas by lexicographic means. The authors use the methods of historical linguistic, comparative-contrastive, etymological, definitional and semantic analysis. The object of the study is German dictionaries and lexicons published from 1513 to 1888. It has been established that the concept of “happiness”, represented in the German vocabulary by the lexeme Glück, has transformed over four centuries along with the growth of people’s material and spiritual needs against the background of the gradual humanization of public life. This has led to the complication of the semantic structure of the lexeme Glück which objectifies this concept. The representation of the Glück lexeme in dictionaries dating back to the early 16th – mid-18th centuries is laconic, due to the type of dictionaries (nomenclatures, translation dictionaries) that did not feature detailed comments on the repertoire of meanings that the desired lexeme possessed. The main elements of the semantic structure of the lexeme are ‘(temporary) prosperity’, ‘bliss’, ‘luck’, ‘destiny (fate)’. The analysis of the interpretation of happiness in the mid-18th century – late 19th century allows one to make a conclusion about the complication of the semantic structure of the lexeme Glück due to a philosophical reinterpretation of this concept and its integrated conveyance by appropriate lexicographic means. The etymology of the word Glück remains unclear. It is assumed that the word appeared in the 13th century and retained a neutral meaning until the end of the Middle High German period when the positive connotation began to prevail in the semantics of the word.
The concept of schastie/bakht (happiness) in the Russian and Uzbek phraseology
Authors: Koroleva Svetlana Borisovna , Latipov Oquil Juraqulovich , Polozhevets Elena Valerievna
Published: September 2021

The article considers the concept of Schastie/Bakht (Happiness) in the Russian and Uzbek linguistic cultures as one of the most important universal concepts with a national component. On the one hand, the study is conditioned by the interest of modern contrastive linguistics in the comparative research of concepts with a national component. On the other hand, it continues scientific works concerned with the concept of Schastie in the Russian linguistic culture and the concept of Bakht in the Uzbek linguistic culture. The novelty of this study is determined by the fact that this concept is compared for the first time using set phrases of two languages and based on an analytical review of the relevant sources. The article aims at determining common and different components for the Uzbek and Russian linguistic cultures with regard to the Happiness concept (according to the data obtained from the analysis of the above-mentioned material). The article presents the results of an analytical review of studies on the concept of Schastie in the Russian linguistic culture and the concept of Bakht in the Uzbek linguistic culture, as well as contrastive analysis of phraseological units related to the verbalization of these concepts. To analyze and compare idioms of two unrelated languages (Russian and Uzbek) and ways of verbalizing the concept, the authors used the method of linguistic and cultural description supplemented by the component analysis of lexemes and the comparative method. As a result, general and specific meanings for the words “schastie” and “bakht” were identified, as well as general and specific components of the Happiness concept.
Implicit notions of a happy person in elementary school students
Authors: Komarova Aleksandra Vladimirovna , Slotina Tatyana Viktorovna , Sitnikov Valery L. , Yashchenko Elena Fedorovna , Zakharov Konstantin Pavlovich
Published: September 2021

The article is devoted to the substantiation and results of a study of implicit notions of a happy person in elementary school students. The methodological foundation is constructed by D.A. Leontiev’s two-level model of happiness, K. Riff’s concept of happiness as the basis of psychological well-being, and V.L. Sitnikov’s concept of the image of a person. The deployed research method is “SPI(H) — the Structure of a Person’s Image (Hierarchical)” (V.Sitnikov) including the verbal and non-verbal associative experiment with the subsequent content analysis. The novelty of the study lies in the comparison of the image of a happy person and self-image through the psychosemantic method including a comparative analysis of the notions of a happy person in children from complete and incomplete families. A happy person is associated by elementary school children with an emotionally positive attitude towards life, a responsible and caring attitude towards people, the presence of a family and active interaction with it, less often with success in educational and intellectual activity and material well-being, as well as the presence of friends. A happy person is idealized by younger students, however, their image is more abstract compared to children’s self-images. Elementary school students from complete families are characterized by greater conformity of the self-image with the image of a happy person whereas only half of the children from incomplete families show such correspondence. The predominant modality of both images is positive in all children. Social, bodily, and metaphorical characteristics are more common in the image of a happy person among children from incomplete families while the conventional social role characteristics dominate among children from complete families. The prospects for further study of the image of a happy person in elementary school children within the framework of family psychology are outlined.
University graduate satisfaction profile as an education quality criterion
Authors: Pereverzeva Marina Viktorovna , Anufrieva Natalia Ivanovna , Kruglova Marina Gennadievna , Mikhaylov Stanislav Nikolaevich , Mamontova Yana
Published: September 2021

Research background: Despite a fairly long tradition of measuring students’ assessment of the quality of obtained university education, there are still many unresolved issues in this area. The aim of the study: to theoretically substantiate the concept of a profile of graduates’ satisfaction with university educational programs including several parameters. The satisfaction profile serves as a criterion of the quality of education, at the same time reflecting students’ subjective assessment of the learning outcomes received at the university that they correlate with their expectations at the stage of admission. The concept is proposed in association with the monitoring of university graduates’ satisfaction with educational programs developed and tested as part of the research work at the Russian State Social University. Methods: graduate satisfaction is assessed using quantitative (questionnaires, the results of which are processed in SPSS) and qualitative (interviews) research methods. The proposed and tested method for the assessment of university graduates’ satisfaction with educational programs can serve as a basis for the development of university systems for monitoring graduates’ satisfaction with educational programs and education quality management and the satisfaction profile can become a universal criterion of education quality assessment not only in Russian but also in foreign universities. Results and novelty: The novelty and significance of the study results lie in the fact that the rating of educational process factors significant for graduates’ satisfaction provides information that can be used for successfully placing the direction of training in the market of educational services. Moreover, two ratings of the importance of the identified factors are constructed. The first one reflects the respondents’ direct assessment that can be used in advertising and information campaigns in the market of educational services. The second rating shows indirect assessment providing a more adequate image of the real impact of various factors on graduates’ satisfaction with educational programs; the results of this rating can be used in the intra-university quality management.
Theme of happiness in Ch. Brontè’s novel ‘Jane Eyre’
Authors: Kovaleva Marina Yurievna
Published: September 2021

The purpose of the study is to trace the development of the theme of happiness in relation to the development of the protagonist in the novel “Jane Eyre” by the English Victorian writer Charlotte Brontè. It is discovered that the pursuit of happiness becomes an internal impetus driving the plot of the novel, ensuring the development of the protagonist’s image and promoting such leitmotifs as creativity, love, freedom, naturalness, and fight for one’s life. Particular emphasis is placed on the search for individual components of the internal and external life that comprise the plotline of the protagonist’s pursuit of personal happiness. At the same time, it is noted that the heroine’s ideas of happiness, while essentially remaining unchanged, obtain different undertones at various stages of growing up. It is also noted that the protagonist’s ideas of happiness sharply differ from some other characters’ ideas of happiness (for example, Helen Burns). It is argued that the protagonist in Charlotte Brontè’s novel is led along the arduous journey to happiness by her natural tenacity and the model of the responsible and naturally creative behavior based on the feeling of love which is formed in the protagonist – with the development of her character – already in her childhood. The academic prerequisites for the study are numerous works on the image of the protagonist, the features of psychologism and realism in Charlotte Brontè’s work, on the one hand, and the increased interest in the problem of happiness in academia, on the other hand. The study of the image of childhood and the place that the pursuit of happiness holds in it carried out by the authors in a previous work is also an important prerequisite for this study. The novelty of this work consists in analyzing the content features of the theme of happiness in Charlotte Brontè’s famous novel.
Francophone literature in search of happiness
Authors: Averkina Svetlana Nikolajevna , Mosova Diana Vladimirovna , Fomin Sergei Matveivich , Shimichev Alexey Sergeevich
Published: September 2021

The article deals with modern French-language literature on the loss of a person’s sense of happiness and harmony. The study authors explore the work of Western European novelists, who not only record the next decline of Europe but also try to return a sense of dignity to their fellow citizens. For centuries, literature has offered various forms of describing the uniqueness of human interaction with the world. If realism gives rise to a literature of explication that thinks aloud, and modernism tries to free the art of realists from layers of pretense, then the oppositional postmodern aesthetics proposes the so-called pluralism of reading practices, which frees both the reader and the literary critic from the need to search for forerunners and origins. Having experienced postmodern delight at the turn of the 21st century, the modern Western European writer en masse returns into the fold of realistic literature, in which a person is determined both socially and historically. At the same time, preference is given to documentary literature, which includes both memoirs, diaries, and essays, and the auto-fictional novel, known today as the “non-fiction” novel which has been in the focus of scholars’ attention for many years. Whatever forms modern literature may use to disguise itself, even if these forms are the most flowery, its main task is to describe a contemporary who lives with an inescapable feeling of the end of the world, trying to regain the meaning of life, to find footholds that are described in such detail by centuries of aesthetic practice. Therefore, the subject of the study is the classical categories: life, family, love, and peace of mind. The purpose of the study is to describe the current state of literature in Western European countries, identify the trends of its development and genre preferences of the experts of culture. The novelty of the study consists in the fact that the concept of “happiness” is investigated for the first time using the example of French-language literature, and the works of writers little studied in Russian criticism, such as A. Makine and Catherine Lovey, are introduced into academic circulation.
Archetypal analysis of “Cinderella”
Authors: Mirskaya Liudmila A. , Pigulevskiy Victor O.
Published: September 2021

Psychologists often use the name of the protagonist of the fairy tale “Cinderella”, which is famous thanks to the brothers Grimm and Charles Perrault, for a sacrificial girl prone to dissociation, illusions, and waiting for a prince. This is typical for psychoanalysis. However, such an idea of Cinderella’s character does not fully reflect the essence of the matter. Moreover, it is generally not true. From the perspective of C.G. Jung’s analytical psychology, Cinderella is not a victim or an infantile dreamer and is not a real girl at all. Any tale represents an archetypal process of individuation. This is a collective natural constant of the psyche that excludes individual problems. Cinderella cultivated in herself what the ancient Greeks called “paideia” – the integrity of the personality and inner strength, influence on others. The purpose of the article is to describe the process of Cinderella’s individualization from the position of C.G. Jung’s archetypal approach based on the amplification method. The most relevant sources of recent years on the archetypal analysis of fairy tales are the works by M.-L. von Franz, H. Dieckmann, and C.P. Estés. The novelty of the study consists in the description and analysis of the archetypal images of the collective unconscious, which underlie the process of Cinderella’s individuation and determine her life path. These archetypal images are Persona, Self, Shadow, Anima/Animus, and the symbolic levels of the individuation process can be represented by such alchemical terms as “separation”, “multiplication”, “calcination”, “initiation”, “transformation”, “conjunction”, “solidification”.

This paper selects data related to each representative industry in the Central Yunnan Urban Agglomeration from 2010-2019 as the research sample, and analyzes the functional structure of the Central Yunnan Urban Agglomeration through spatial Gini coefficient, primacy and location quotient. The research results show that: the economic development level of Kunming, a city with high primacy, is insufficient. Moreover, the development differences within the Central Yunnan Urban Agglomeration are large enough and it’s hard to drive economic recovery. The industrial agglomeration of the Central Yunnan Urban Agglomeration is not high. There are fluctuating changes in industries that depend on the natural environment, and the epidemic has a large impact on the pillar industries as well. There are overlapping industrial functions within the Central Yunnan Urban Agglomeration. The complementarity of each function is not high enough, and the degree of regional economic integration is not enough, which is not conducive to economic recovery.

Authors: Yang Xinru , Ding Yigang
Published: September 2021

With the development of the digital age, “digital learning and innovation” is becoming more and more important in the core literacy of information technology discipline. Through the elaboration of relevant concepts, this paper explores the connotation and concrete performance of “digital learning and innovation” literacy of senior high school students, and then obtains its three manifestations: the collection and management of digital learning resources, the adaptation of digital environment, the application and innovation of digital learning resources. On this basis, a questionnaire survey was designed to understand the status of “digital learning and innovation” literacy of high school students in S Middle School of Anhui Province, and the data results were analysed. It was found that senior high school students generally have this literacy, but some students still have some problems and need teachers’ timely guidance. Therefore, this study further proposes strategies for achieving high school students’ “digital learning and innovation” literacy to assist teachers in reminding students of “digital learning and innovation literacy” in teaching.

Folgen einer vorderen Kreuzbandruptur – Ein systematisches Umbrella-Review
Authors: Diemer Frank , Zebisch Jochen , Saueressig Tobias
Published: September 2021

Einleitung Die Behandlung einer vorderen Kreuzbandruptur wird nach wie vor kontrovers diskutiert. Insbesondere die Frage: Konservative oder operative Versorgung? steht dabei im Mittelpunkt. Für die Beantwortung dieser Frage werden häufig Folgeschäden wie die Entwicklung einer posttraumatischen Arthrose, Sekundärschäden am Meniskus oder Knorpel und auch die Partizipation im Sport herangezogen. Sollten zwischen den einzelnen Behandlungsoptionen bedeutsame Unterschiede bezüglich dieser Parameter bestehen, so wären die Ergebnisse für die Entwicklung evidenzbasierter Behandlungspfade von hoher Bedeutung. Ziel dieser Arbeit war es daher, die Entwicklung einer Gonarthrose nach einer Ruptur des vorderen Kreuzbandes und der entsprechenden Behandlung (konservativ oder operativ) zu evaluieren.

Material und Methoden Zur Beantwortung der Fragestellung wurde eine systematische Literaturrecherche in der Medline über Pubmed, der Cochrane Library und in CINAHL durchgeführt. Die Recherche wurde im Januar 2020 durchgeführt und im Januar 2021 wiederholt. Eingeschlossen wurden ausschließlich systematische Reviews mit einem minimalen Nachuntersuchungszeitraum von 10 Jahren. Untersuchte Kohorten umfassten Patienten mit einer entweder konservativ oder operativ versorgten Ruptur des vorderen Kreuzbandes. Die Diagnose Arthrose wurde entweder radiologisch (anerkannte Scores) oder klinisch (Schmerz und Funktionseinschränkung) gestellt. Passende Übersichtsarbeiten wurden mit dem AMSTAR-2-Fragebogen einer qualitativen Bewertung unterzogen.

Ergebnisse Die Literaturrecherche ermittelte zunächst n = 42 Übersichtsarbeiten, von denen 14 Arbeiten inkludiert werden konnten. Nach der Volltextprüfung und der qualitativen Bewertung verblieben zur Auswertung der Ergebnisse lediglich n = 2 systematische Reviews. Die Ergebnisse beider Arbeiten zeigen unpräzise Daten mit einer großen Variabilität. Es kann aber mit großer Wahrscheinlichkeit davon ausgegangen werden, dass das Risiko für die Entwicklung einer Gonarthrose nach einer Ruptur des vorderen Kreuzbandes erhöht ist. Eine Reduktion der Inzidenz der Gelenkdegeneration durch eine Rekonstruktion des vorderen Kreuzbandes ist nicht nachweisbar, genauso wenig wie ein Unterschied bei einem direkten Vergleich zwischen konservativer und operativer Versorgung.

Schlussfolgerung Patienten mit einer vorderen Kreuzbandruptur tragen mit hoher Wahrscheinlichkeit ein größeres Risiko für eine progressive Gelenkdegeneration. Ein pauschaler protektiver Effekt einer Kreuzbandplastik ist in den ausgewerteten Arbeiten nicht nachweisbar. Aus diesem Grund sollten innerhalb der Entscheidungsfindung über operative versus konservative Versorgung andere Faktoren wie die funktionelle Instabilität noch höher bewertet werden.
