„Doch nicht auf Russisch!“ – Perspektiven von Kindern auf Sprachbildungsprozesse im Rahmen familialer Vorlesesituationen mit mehrsprachigen Bilderbüchern
Authors: Vishek Svetlana
Published: December 2021

Sprachbildung findet nicht nur in Bildungseinrichtungen statt. Der sprachliche Alltag in der Familie ist mindestens genauso ausschlaggebend für die Enkulturation von Kindern wie das Bemühen von pädagogischen Fachkräften. Dieser Beitrag widmet sich aus diesem Grund der familialen Vorlesepraxis im Kontext der Mehrsprachigkeit als Moment sprachlicher Bildung und des Austauschs. Im Fokus stehen die Positionierungen der Kinder zu ihrem Sprachgebrauch sowie zu den Sprachbildungsprozessen, die sich im Rahmen der exemplarischen Vorlesesituationen beobachten lassen. Sichtbar wird dabei besonders die Rolle der einzelsprachübergreifenden Sprachverwendung für die Partizipation der Kinder im Rahmen der informellen Sprachlernsituation. Den theoretischen Rahmen bildet die Schnittstelle zwischen Lesesozialisationsforschung und soziokulturellen lerntheoretischen Ansätzen. Die Rekonstruktion der Perspektive der Kinder erfolgt mithilfe des gesprächsanalytischen Zuganges (Deppermann, 2000).
Inequality, social justice and the purpose of Early Childhood Education
Authors: Press Frances , Cooke Mandy , Gibbs Leanne , Warren Robbie
Published: December 2021

Early childhood education and care (ECEC) – as with education more generally – should be a central plank of a suite of social policies designed to support more socially just societies. However, universal access to ECEC in itself, will not redress inequalities. This paper draws upon reports from the Australian Children’s Education and Care Quality Authority (ACECQA), and data from three doctoral studies nested within the Australian Exemplary Early Childhood Educators at Work research project, to argue for attention to the quality of the early childhood system and to consider the contribution that a deeply embedded socially just purpose makes to quality.

Published: December 2021

Marine diesel engine is developing towards the direction of precision, automation and systematization, and it has the characteristics of complex structure and many parts. If it breaks down, it will affect the operation safety of the whole ship. If it is serious, accidents may occur, which may cause maritime accidents. Therefore, how to prevent the occurrence of marine diesel engine failure and analyze the cause of failure after the accident has been paid more and more attention by scholars at home and abroad. In the simulation study of the working process of diesel engine, for different types of diesel engines, the laws of combustion process are different, even for the same diesel engine in different working conditions, the combustion laws are also different, which will cause great difficulties to study the combustion process. Using computer simulation technology, the physical calculation model of diesel engine system is established by simulating the typical combustion faults of marine diesel engine. AVL-FIRE software is used to simulate different faults of diesel engine combustion process, and the changes of various performance parameters of diesel engine under corresponding faults are obtained, so as to grasp its working state macroscopically, and provide relevant basis for the design, optimization and operation management of diesel engine system.

Published: December 2021

Now there are more and more new energy vehicles on the road, compare to the traditional vehicles that use the oil to offer the power, the new energy vehicles use electric or hydrogen to offer the power, which have no exhaust pollution emission, but also have non-exhaust emission. Brake and tyre system are the special components of vehicles due to the frequent replacement, they are the main source of the non-exhaust emission. Brake system is one of the most important safety systems of vehicles. The system can reduce the speed of the vehicle and keep the vehicle stable when going downhill. Friction between brake disc and pads or shoes during driving creates small particles that are released into the atmosphere, soil and rivers. The particles have different dimensions, some element or matter inside maybe harmful to human and environment. So it is very important to know more about the non-exhaust brake emission. Here, we focus on the specification of GRPE-81-12 “Non-Exhaust Brake Emissions – Laboratory testing – Part 1: Inertia Dynamometer Protocol to Measure and Characterise Brake Emissions Using the WLTP-Brake Cycle” and do the detailed interpretation.

Authors: Wu S , Liu Y J
Published: December 2021

The two-body oscillating type wave energy converter (WEC) is a hot research topic at present. A two-body device with damping disc was taken as the test model in this paper. The two bodies were connected by a hydraulic piston cylinder to realize the relative motion energy conversion. Physical experiments were carried out in a wave-making flume to study the operation performance. The effects of wave elements and load on the hydrodynamic characteristics and capture width ratio (CWR) of the model were analysed respectively. The results showed that wave frequency and external load were the main factors affecting the motion response and energy conversion of the device. With the increase of wave frequency and external load, the response amplitude operator (RAO) and the capture width ratio both increase first and then decrease. Wave height has little effect on system characteristics. There exists a best-matching wave period condition, and the optimal motion response and energy conversion are obtained.

Mechanical Characteristics and Failure Modes of Low-Strength Rock Samples with Dissimilar Fissure Numbers
Authors: Wang Y L , Liu D S , Li K , Chen D , Hu X M
Published: December 2021

The mechanical characteristics and failure modes of low-strength rock sample with various crack dip angles and numbers were investigated by conventional uniaxial compression test and three-dimensional (3D) crack reconstruction. The results indicated that compared with high-strength rock masses, cracks had different influences on the low-strength rock mass mechanical deformation features. Thereinto, the number of fissures can cause post-peak failure stage of stress-strain curve change from swift decline to multi-step down and horizontally extended decline, respectively, showing obvious ductility and ductile-flow deformation and failure characteristics. Due to the structural effect, only under the condition of fissure α < 90°, the modulus of peak strength and elastic modulus lowered with the enhancement of fissure number and had a negative correlation. As the number of fissures increased, the axial peak strain increased first and then decreased, demonstrating a reversed V-shaped change trend. Fissure number can fully affect the crack propagation law only in the case of vertical fissures. The above research findings can complement and improve the study of fissured rock masses.
Research on the Tensile Properties of Packaging Film Based on Environmental Protection PVA-KGM
Authors: Xiong Ligui , Zhang Liqiong
Published: December 2021

Konjac glucomannan (KGM) and poly (vinyl alcohol) (PVA) were mixed to form gel-like polyelectrolyte solution with glycerol and sorbitol as compound plasticizer, which was used to prepare packaging films via casting and drying. The results show that the tensile strength and elongation at break of the packaging films drop sharply when the blending temperature and blending time exceed 80 °C and 3.5 h. When the mass ratio of sorbitol and glycerol in the compound plasticizer ranges from 1:1 to 1:3, it is beneficial to improve the tensile strength of the packaging films. The microscopic reasons for the change of the tensile properties of the packaging films are mainly caused by diffusion-stop-continuing diffusion—precipitation of low-molecular electrolyte, which makes the system shift from equilibrium-homogeneous state- unbalanced state—heterogeneous state.
Influence of Axial Clearance on Water-Jet Axial Flow Pump
Authors: Li Chen , Wang Hongming
Published: December 2021

Three dimensional Reynolds averaged N-S equation and S-A turbulent model were adopted to simulate the flow field and hydraulic performance of the waterjet axial flow pump with the different impeller axial clearance. The numerical research results show that with the increase of axial clearance size, total pressure and static pressure rise at first and then decreases, torque and shaft power remain basically unchanged, the efficiency decreases gradually, the suction surface separation zone of stator expanded under the design condition. When the axial clearance is 30mm, the pump hydraulic performance and flow field are the best, and stator load distribution is the most uniform. When the axial clearance is 40–50mm the load of the lower part of stator leading edge is reduced greatly, which is not conducive to maintain static blade strength and maintain the stator rectifying action.

Effect of Leading-Edge Bulges on Aerodynamic Characteristics of Bionic Wingsail
Authors: Li Chen , Sun Peiting , Wang Hongming
Published: December 2021

The leading-edge bulges along the extension direction are designed on the marine wingsail. The height and the spanwise wavelength of the protuberances are 0.1c and 0.25c, respectively. At Reynolds number Re=5×105, the Reynolds Averaged Navier-Stokes equations are applied to the simulation of the wingsail with the bulges thanks to ANSYS Fluent finite-volume solver based on the SST K-ω models. The grid independence analysis is carried out with the lift and drag coefficients of the wingsail at AOA = 8° and AOA=20°. The results show that while the efficiency of the wingsail is reduced by devising the leading-edge bulges before stall, the bulges help to improve the lift coefficient of the wingsail when stalling. At AOA=22° under the action of the leading-edge tubercles, a convective vortex is formed on the suction surface of the modified wingsail, which reduces the flow loss. So the bulges of the wingsail can delay the stall.

Published: December 2021

In the process of technological progress and development, many industries are moving towards artificial intelligence (AI) technology, which is a construction and combination of multi-thinking technology. But in terms of structure, material development and diversification, the source of ideas is still inseparable from the natural world. Therefore, when faced with solving problems, many scientists not only conduct in-depth research on changes in cells, tissues and expansion, to solve the multi-dimensional movement of current technology, but also non-destructively explore the thermal effects of friction. Self-generated lubrication or external additives are used to solve the demand, so that the reciprocating movement of the piston can be more effective, and each cycle can be achieved. According to research and discussion, in each cycle, heat engine and cooling, speed movement frequency and lubrication method are different, which not only makes the piston have different effects, but also the reaction and sensitivity will greatly change, which makes it necessary to stop resting. Therefore, this research is primarily aimed at exploring the reciprocating motion of the human-machine “Indirect piston” and the efficiency of internal friction. The purpose is to have a more in-depth study of the piston theory, so as to have a deeper foundation for the movement of derived multi-dimensional angles in the future. In the future, there will be better development in injection, piston mechanism, and lubrication.

Accounting for Sentence Position and Legal Domain Sentence Embedding in Learning to Classify Case Sentences
Authors: Xu Huihui , Savelka Jaromir , Ashley Kevin D.
Published: December 2021

In this paper, we treat sentence annotation as a classification task. We employ sequence-to-sequence models to take sentence position information into account in identifying case law sentences as issues, conclusions, or reasons. We also compare the legal domain specific sentence embedding with other general purpose sentence embeddings to gauge the effect of legal domain knowledge, captured during pre-training, on text classification. We deployed the models on both summaries and full-text decisions. We found that the sentence position information is especially useful for full-text sentence classification. We also verified that legal domain specific sentence embeddings perform better, and that meta-sentence embedding can further enhance performance when sentence position information is included.

METHODS:

In the present study, eighty patients (aged 18–80 years old) were randomly assigned to receive daily either ALA (600 mg/day) or placebo for eight weeks. Systolic BP (SBP), Diastolic BP (DBP), Triglyceride (TG), Total cholesterol (TC), Low Density Lipoprotein (LDL), and High Density Lipoprotein (HDL) were measured before and after intervention.

RESULTS:

LDL decreased significantly in the ALA group (110.6±34.9 vs. 107.9±33.4 mg/dl; P < 0.05). There was also a significant difference in terms of HDL in both groups (Δ= +1.8 vs. Δ= –0.3 mg/dl; P < 0.05). A marginal non-significant reduction was also observed for SBP. There were no significant differences in other variables between the two groups.

CONCLUSIONS:

ALA supplementation did not improve the BP and some serum lipid markers in critically ill patients. Larger and longer trials will be needed to determine efficacy of ALA.

The article is devoted to the analysis of the Draft Law "On Ensuring the Safety of Participants in Criminal Proceedings and Other Persons in the Interests of Justice". The system of current legislation in the field of security of persons involved in criminal proceedings is outdated and does not provide the necessary conditions for the proper administration of justice. It is established that the current legislation in the field of protection of participants in criminal proceedings is unreformed, has many gaps and is ineffective. It was stated that participants in criminal proceedings (witnesses and victims) who are in real danger often refuse to testify and cooperate with the investigator, as they believe that the state cannot protect them from the unlawful influence of persons involved in criminal proceedings. As a result of the refusal of witnesses and victims to testify and cooperate with the investigation, the perpetrators remain unpunished. On the positive side of the draft law is the proposal to establish a new specially authorized body - the National Agency for Security of Criminal Proceedings, as in the event of a high level of threat to certain participants in criminal proceedings, their rights and freedoms, life and health must be preserved. It was found that the Draft Law does not provide for the specifics of ensuring the safety of juvenile participants in criminal proceedings, which significantly violates the rights of this vulnerable category of persons. Based on the understanding of the list of persons entitled to the application of security measures proposed in Part 1 of Art. 6 of the draft Law, it can be understood that the legislator provided for the possibility of taking under the protection of a minor, in one form or another, but unfortunately bypassed the attention of their parents and legal representatives. In view of the above and taking into account the concept of "best interests of the child", it is proposed to expand the list of persons subject to protection and add a legal representative of a minor. There have also been a number of other proposals to improve the situation of juveniles who are being protected by the state for giving incriminating testimony. It is concluded that the bill needs to improve and maximize its efficiency and effectiveness of its rules.

The institute of ensuring the security measures to persons carrying out special tasks detecting the criminal activities of an organized group or criminal organization is called to protect these persons, as they may be in danger during the criminal process, and in most cases after its completion. Therefore, it is advisable to find out the definition and main directions of improving the security measures to persons carrying out special tasks detecting the criminal activities of an organized group or criminal organization. The effectiveness of security measures to persons carrying out special tasks detecting the criminal activities of an organized group or criminal organization should be understood as creating in a minimum time and taking into account human rights and freedoms the necessary safe conditions for proper performance of a special task to document criminal activity of an organized group or a criminal organization. The main directions of improving the effectiveness of security measures to persons carrying out special tasks are: improving the rules of application of security measures to persons carrying out special tasks; improving the content of the grounds and procedural procedure for ensuring the safety of persons carrying out special tasks; reduction of time limits for the application of security measures to persons carrying out special tasks; expanding the types of security measures applied to persons carrying out special tasks; improving the financing and logistics of security measures to persons carrying out special tasks. Methodical and forensic security of the security of criminal justice participants, in our opinion, will include the development of methodological recommendations on issues of such peculiarities of investigating certain types of crimes that are determined by the security of individuals. We believe that these methodical and criminology recommendations will reflect the peculiarities of the interaction of law enforcement agencies in the process of ensuring the safety of participants in criminal justice and the use of special knowledge, cooperation with national state institutions, law enforcement agencies of other countries, etc. At the same time, criminalistic recommendations may become a structural component of techniques for investigating certain types of crimes, such as corruption, crimes against national security, etc.

Published: December 2021

The article considers the problem of formation of tolerance as a component of competence of future policemen and policewomen, defines the concepts and structural components of tolerance. It is substantiated that tolerance is one of the most important qualities and general cultural competencies of a person, which is most effectively formed on the basis of a certain model of learning. The study emphasizes that the structural model is a part of the learning process and includes such components as: target, incentive-motivational, content, procedural, control-regulatory, evaluation-effective ones. In the scientific work an attempt is made to give a brief description of some components of the educational process in the context of the research topic, namely: target, stimulating-motivational, meaningful components. The target component of the learning model, which aims to form tolerance, should be in order to create favourable conditions for identifying, initiating and using individual (subjective) personal experience of tolerance and a certain educational environment based on the principles of tolerance pedagogy and, above all, willingness to accept others as they are, as well as interact with them on the basis of consent and understanding. The next structural component of the above mentioned model is the incentive-motivational component, which includes motivation for a deeper study of the proposed issue of all participants in the pedagogical process; determining the level of knowledge of applicants on the problem of tolerance, etc. Changing the target orientation of learning changes the emphasis in the semantic component of learning, as in the process of learning the main system-forming element is the content of learning (learning material that embodies the goals of learning). Tolerance, which is presented in the form of a structural model and a brief description of the individual components, allows to make assumptions about the further study of the structural components of the pedagogical process and their role in the formation of personality tolerance.
HALYCCIAN RURAL COMMUNITY OF THE EARLY TWENTIETH CENTURY AS THE BASIS OF CIVIL SOCIETY. BY THE WORKS OF V. STEFANYK (TO THE 150TH ANNIVERSARY OF THE WRITER'S BIRTH)

The article considers the life of the Galician rural community of the early twentieth century, reflected in the works of Vasyl Stefanyk, the embodiment of the writer’s socio-political views. The spiritual foundations of the public rural system, which exist in the people’s consciousness at the genetic level and which act as a regulator and a reliable guardian of public order, have been analyzed. The authors trace how the new socio-political conditions cause changes in public life and what role the educated intelligentsia plays in these processes. In order to lead the people, it is necessary to understand them, to inspire their trust. Fiction is first and foremost an art. In the article, the writer’s ideas are presented through the interpretation of full-length, relief images, artistic details that express his ideas about the rural community. V. Stefanyk is an expressionist, so he portrays a person in extreme situations, in moments of the highest emotional tension, with a naked soul. This style of writing allows the author to achieve the maximum level of truthfulness. As a result, it was noted that at the beginning of the twentieth century there were traditions of collective solution of social problems in Ukraine, peasants sought to develop through education to improve their lives, to learn to defend their rights. Communities also took care of national life: they honored national heroes who became national symbols, because it was clear that without a common cultural memory, the images of which acquire symbolic significance, it was difficult to unite the people. Thus, Ukrainians have long traditions of public life that were interrupted during Soviet totalitarianism, but now the people are gradually returning to them, especially at critical moments in history when it is necessary to unite to confront the threats to democracy. As you can see, socio-political life continues in a cultural context, which is often determined for it. In view of this, it is promising to study the reflection of society in Ukrainian artistic literature, which depicts being in its entirety and diversity.
