"Pedagogical rhetoric" and "Ontolinguistics" as courses taught at the department of pedagogy of st. Tikhon’s orthodox university for the humanities

The study is in line with the problem relevant for modern pedagogical science related to the formation of competencies in future teachers necessary for the effective organization of pedagogical communication in various educational and speech situations. In this regard, the work reflects the experience of teaching such educational disciplines as "Pedagogical Rhetoric" and "Ontolinguistics," which for the first time began to be implemented in spiritual educational institutions of the Russian Orthodox Church since 2015 at the Department of Pedagogy of the Historical and Philological Faculty of PSTGU. When presenting the material, a justification is given for the relevance of including educational disciplines in the structure of educational programs aimed at the formation of rhetorical and ontopsycholinguistic competencies among students. A description of the educational programs in the disciplines "Pedagogical Rhetoric" and "Ontolinguistics" implemented within the framework of the bachelor's and master's studies of the Department of Pedagogy of PSTGU is given: their concept and content, purpose and planned results of development, as well as educational and methodological support and forms of intermediate certification are described. It is noted that the basic theoretical setting of the developed curricula is the statement that linguistic ability is a universal and distinctive feature of man as an image of God, which the teacher is called upon to constantly improve together with the spiritual and moral qualities of the person. It is concluded that the presented author's curricula of the disciplines "Pedagogical Rhetoric" and "Ontolinguistics" are to a certain extent innovative, their concept and content are due to the current trends in the development of modern humanitarian science (linguistics, pedagogy, psychology), as well as the formation of an interdisciplinary scientific approach that contributes to the formation of "whole knowledge" about the studied phenomena of pedagogical reality.

General Theory of Future Law: Definitions, Innovative Potential

The article actualizes promising ideas that have the innovative potential for the formation of new institutional and functional elements of the law of the future. The legal system is one of the more conservative spheres of public activity. The general theory of law is a constant paradigm oriented to the traditional and fundamental components. However, the rapid development of the socio-cultural space produces challenges and threats, requiring the reaction of the legal environment. The purpose of scientific exploration is to identify specific aspects of the general legal space that require improvement and transformation; as well as to realize the feasibility of using the definition “general theory of law of the future”. The objectives of the article are to analyze contemporary legal concepts and ideas that can actualize transformations in certain segments of jurisprudence in the short-termand long-term strategy. The methodology that was used to achieve the objectives of scientific exploration can be divided into several clusters: general scientific methods, individual scientific methods, special methods of scientific legal discourse. The result of the research is the development of theoretical and methodological settings (dynamism, flexibility,and efficiency), which will be relevant to the legal paradigm in the future. So, the general theory of law has historically proved its effectiveness and relevance for civilizational development and does not require cardinal revolutionary changes, however, it is necessaryto transform some legal institutional and functional elements in response to the rapid and permanent changes in the socioculturalspace.

QDataSet, quantum datasets for machine learning

The availability of large-scale datasets on which to train, benchmark and test algorithms has been central to the rapid development of machine learning as a discipline. Despite considerable advancements, the field of quantum machine learning has thus far lacked a set of comprehensive large-scale datasets upon which to benchmark the development of algorithms for use in applied and theoretical quantum settings. In this paper, we introduce such a dataset, the QDataSet, a quantum dataset designed specifically to facilitate the training and development of quantum machine learning algorithms. The QDataSet comprises 52 high-quality publicly available datasets derived from simulations of one- and two-qubit systems evolving in the presence and/or absence of noise. The datasets are structured to provide a wealth of information to enable machine learning practitioners to use the QDataSet to solve problems in applied quantum computation, such as quantum control, quantum spectroscopy and tomography. Accompanying the datasets on the associated GitHub repository are a set of workbooks demonstrating the use of the QDataSet in a range of optimisation contexts.

A distribution-based selective optimization method for eliminating periodic defects in harmonic signals

Due to environmental interference and defects in measured objects, measurement signals are frequently affected by unpredictable noise and periodic defects. Moreover, there is a lack of effective methods for accurately distinguishing defect components from measurement signals. In this study, a distribution-based selective optimisation method (SOM) is proposed to mitigate the effects of noise and defect components. The SOM can be seen as a binary- or multiple-class signal classifier based on an error distribution, which can simultaneously eliminate periodic defect components of measurement signals and proceed with signal-fitting regression. The effectiveness, accuracy, and feasibility of the SOM are verified in theoretical and realworld measurement settings. Based on theoretical simulations under various parameter conditions, some criteria for selecting operation variables among a selection of parameter conditions are explained in detail. The proposed method is capable of separating defect components from measurement signals while also achieving a satisfactory fitting curve for the measurement signals. The proposed SOM has broad application prospects in signal processing and defect detection for mechanical measurements, electronic filtering, instrumentation, part maintenance, and other fields.

Direct ink writing of dense strontium ferrite parts by staggered and overlapped stacking method

An innovative process was proposed to solve the limitations of direct ink writing (DIW) in the manufacture of dense ceramics. Dense strontium ferrite parts were successfully prepared by DIW. This innovative process that the staggered and overlapped stacking effectively eliminated the gaps among adjacent printing filaments, which could also be applied to other additive manufacturing technologies. The density and mechanical properties of samples were remarkably improved based on theoretical calculation and program setting. Results show that compared with staggered stacking method, the relative density of samples prepared by staggered and overlapped stacking method increased from 97.42 ± 0.20% to 99.35 ± 0.20%, and the surface roughness reduced from 11.42 ± 0.50 μm to 5.48 ± 0.50 μm. The three-point bending strength and compressive strength of sintered samples were 84.00 ± 5.00 MPa and 610.00 ± 20.00 MPa, respectively.

Mini-Workshop: Mathematics of Dissipation – Dynamics, Data and Control

Dissipation of energy — as well as its sibling the increase of entropy — are fundamental facts inherent to any physical system. The concept of dissipativity has been extended to a more general system theoretic setting via port-Hamiltonian systems and this framework is a driver of innovations in many of areas of science and technology. The particular strength of the approach lies in the modularity of modeling, the strong geometric, analytic and algebraic properties and the very good approximation properties.

Bitung Special Economic Zone (SEZ): A Dynamics Study of Establishment and Development Processes

<p><em>In the context of regional development in Indonesia, Special Economic Zones (SEZs) are designated to accommodate industrial and economic activities for regional acceleration. To date, Indonesia has 19 Special Economic Zones that have been designated, one of which is the Bitung SEZ. In its designation, the Bitung SEZ focused on the fishery and coconut processing industry, as well as its derivative products. The development of the Bitung SEZ as a government product in the plan is expected to give trickling down effects to the surrounding, but in the practice, it does not escape problems (in the spatial, institutional, and socio-economic aspects). Thus, this paper aims to explain how the establishment and operational dynamics of the Bitung SEZ are based on the physical, policy, and social dimensions as dualism in development. This research used mixed methods, with data sources and materials obtained from the research, news, and planning documents. The findings of this study, the dualism of development occurs in both theoretical and practical settings, instead of creating a new growth center, development can also cause some problems.</em></p>

Assessing the effects of fiscal policy news under imperfect information

Abstract We study the transmission of fiscal policy under imperfect information where government spending is composed of permanent and transitory components. Agents learn about the previous processes by only observing overall public spending and a noisy signal. Under this theoretical setting, we construct a novel measure of fiscal policy news and show that the estimated variable agrees with the historical narrative evidence for the US economy. Our measure captures sluggish information shocks rather than revisions with the benefit of being generated by a theoretical model. We then document the effects of this proxy on economic activity by using local projection methods. The results indicate that real activity indicators exhibit delayed positive effects. We also notice that public debt shrinks and tax revenues increase after 2 years due to the delayed output expansion in the aftermath of the fiscal news shock.

The dollar enablers and panhandlers: US capitalist power and the origins of the financialisation at the periphery

Abstract The article discusses the political economy of financialisation in developing countries, defending that US power was crucial to driving it, while the indebted dependent states acted not only as dollar panhandlers but also as dollar enablers. To avoid excessively ‘outside-in’ apprehensions of US power in the capitalist bloc, we debate interpretations that use the concepts of structural power and internationalisation of the state to highlight some political effects of increasing international economic integration and capitalist wealth interpenetration. The theoretical discussion sets the stage for the presentation of declassified documents that illustrate how financial leverage has combined with some converging capitalist goals to entrench neoliberalism and financialisation in the Global North and the Global South. Our contribution serves to caution heterodox economists not to frame national autonomy only in terms of policy analysis, urging them to mobilise critical theory to imagine beyond the established frameworks for action.

When Less Is More: Towards A Theory without A Fixed Address

Theorization is rendered more necessary than ever by globalization, it is the most privileged manner of delineating phenomena and articulating the manifest; without it, anthropological unity is denied and regression to self-destructive competition for survival and domination becomes inevitable. Revathi Krishnaswamy expounds that, rather than mere explicit bodies of theory, an inclusive approach to literature should welcome implicit, latent, emergent concepts and practices from every excluded area, every language and every cultural minority. The aim of this diversification runs against radical relativism, it is a quest for aesthetic and other universals beyond all the particular features that construct actual literary practices. Similarly, in the complex dialogic exchange staged by Ranjan Ghosh and J. Hillis Miller, the two thinkers practice and exhibit a kind of “rooted cosmopolitanism” (Appiah): it would seem that, to exploit texts in context, or to transfer a theoretical set from one culture to another, you need to belong somewhere, to possess and be possessed by some origin. Contrary to the narrative of rooted extension that remains linear even if it is liable to bifurcate, experimental cosmopolitanism considers that we owe no debt to initial or prior circumstance and that our obligations and initiatives, determined by species and trans-species solidarity, apply in the framework of spatial proximity for practical reasons exclusively.

The syntax of existential constructions

This study, in two parts, endeavors a novel analysis of existential constructions, based on a different theoretical setting of clause structure, where the predicate is taken as a necessary and sufficient constituent of the clause. Leaning on this perception, the analyses of existential constructions developed here tries to overcome the discrepancy between form and (semantic and informational) meaning in Hebrew existential constructions. The main part of the study deals with affirmative existential-presentative constructions, used to introduce referents into the discourse. Most of the constructions have been analyzed as consisting of an existential constituent, viewed as a modal marker, and a pivot, regarded as the core component of the predicate domain. This analysis is shown to be valid for both the existential marker jeʃ and for its suppletive verbal forms, derived from √hjj ‘be’. A distinction is made between verbal forms with non-referential and referential verb-bound person markers, where the latter, found with expected, known or given pivots, function as focus marking devices, coming in complementary distribution with prosodic marking of focus. Thus, presentative-existential sentences are formed as unipartite sentences, consisting of only a predicate domain. The last two sections of Part I deal with constructions where the existential constituent follows the pivot and with constructions where the pivot is definite. Part II deals with other existential constructions, including negative constructions; bipartite existential sentences; existential constituents as sole constituents in a sentence; existential constituents with clitic referential markers; and the use of existential markers as interjections or discourse markers.

Inquiry-based Science Teaching through Constructionism: a path towards scientific literacy

Inspired by the concept of bricolage brought by Seymour Papert to education, this work articulated a theoretical and methodological set composed by Constructionism, Inquiry-based Science Teaching and Augmented Reality, aiming to achieve Scientific Literacy indicators. This articulation was concretized in a biology didactic planning, experienced in the second year of high school in a public school. The search for scientific literacy indicators was carried out by means of Textual Discourse Analysis. The results show that the theoretical-methodological set led the students to construct several indicators proposed in the literature of the area. We conclude that constructionist approaches via inquiry teaching are a viable path to scientific literacy and suggest that bricolage should be a strategy encouraged in basic education teacher training or improvement courses.

The problem of professional competencies formation and development is essential under the current circumstances, as competition among production organizations increases every day. Moreover, employers are interested in highly qualified workers who are ready to achieve effective production results and contribute to the prosperity of companies via the implementation of theoretical knowledge and practical skills. The purpose of the article is to analyze the process of formation of professional competencies among employees. In this article, special attention is paid to the analysis of the most important competencies and skills of employees necessary for the full functioning of labor relations in the production process. Also, in this article, the competence-based approach to the implementation of practice-oriented training at the university for the preparation of potential employees, who are able to compete and adapt to the emergence of the latest modern technologies, has been examined and analyzed. The introduction of a competence-based approach into the higher education system is a new step in the training of highly qualified personnel who has not only a set of theoretical knowledge, but is also ready to implement the practical skills to solve various production tasks. An employee, who has received a high-quality higher education, a rich theoretical set of knowledge and practical skills, will apply his / her abilities in his work, demonstrating high efficiency. The results are presented via practical recommendations for employers and educational organizations concerning the employees formation of professional competencies.

Optimizing Object Storage System by the Object Multi-Tiered Balanced Organization

The era of big data has been constantly producing a huge amount of small files that will cause problems such as uneven distribution of copies and massive random readings and writings, resulting in delays in data accessions and degrading performances. By aiming at resolving the problems of an object storage system concerning the organization of small file objects such as layout imbalance, uneven loading, and adaptability of poor data migration, this article introduces a new strategy for object organization called object multi-tiered balanced organization strategy (OMBOS) with improved performance on massive small files in a real object storage system. Apart from the conventional strategy, the OMBOS achieves a multi-level balanced object by establishing weight indicators that reflect the comprehensive performance of nodes, including the balanced distribution of objects between replica sets and the balanced distribution of I/O requests in the replica sets as well as adapting to the equilibrium of the scale changes of the system dynamics. The OMBOS establishes a comprehensive performance evaluation model based on the fuzzy analytic hierarchy process and calculates the performance weights of the nodes of the object storages and replica sets. Then, the consistent hash-based object placement between the replica sets algorithm (BROP) and the I/O-loading balance in the replica set algorithm (IRIB) are utilized to implement performance-weighted objects in the object storage system through a tiered organization when the performance weights are taken into account. When the system scale changes flexibly, data migration is the only performed process in the nodes by adding or removing nodes, so data will not be migrated between existing nodes. Hence, the amount of data migration reaches the theoretical setting. Experiments show that the OMBOS achieves a balanced layout of objects based on performance weights, which meets the balancing and adaptability requirements of data organization. When compared to the original layout strategy through the balanced layout of objects, it performs nearly double the random access method.

Bridging and Improving Theoretical and Computational Electrical Impedance Tomography via Data Completion

In computational PDE-based inverse problems, a finite amount of data is collected to infer unknown parameters in the PDE. In order to obtain accurate inferences, the collected data must be informative about the unknown parameters. How to decide which data is most informative and how to efficiently sample it is the notoriously challenging task of optimal experimental design (OED). In this context, the best, and often infeasible, scenario is when the full input-to-output (ItO) map, i.e., an infinite amount of data, is available: This is the typical setting in many theoretical inverse problems, which is used to guarantee the unique parameter reconstruction. These two different settings have created a gap between computational and theoretical inverse problems, where finite and infinite amounts of data are used, respectively. In this article we aim to bridge this gap while circumventing the OED task. This is achieved by exploiting the structures of the ItO data from the underlying inverse problem, using the electrical impedance tomography (EIT) problem as an example. To accomplish our goal, we leverage the rank structure of the EIT model and formulate the ItO matrix\textemdash the discretized ItO map\textemdash as an $\mathcal{H}$-matrix whose off-diagonal blocks are low rank. This suggests that, when equipped with the matrix completion technique, one can recover the full ItO matrix, with high probability, from a subset of its entries sampled following the rank structure: The data in the diagonal blocks is informative and should be fully sampled, while data in the off-diagonal blocks can be subsampled. This recovered ItO matrix is then utilized to present the full ItO map up to a discretization error, paving the way to connect with the problem in the theoretical setting where the unique reconstruction of parameters is guaranteed. This strategy achieves two goals: (I) it bridges the gap between the finite- and infinite-dimensional settings for numerical and theoretical inverse problems and (II) it improves the quality of computational inverse solutions. We detail the theory for the EIT model and provide numerical verification to both EIT and optical tomography problems.

Some implicative topological quasi-Boolean algebras and rough set models

In this paper a number of implicative topological algebras have been developed which are based on the implicative quasi-Boolean algebra with operator (IqBaO) [10]. Their independence is established by several examples. Logics corresponding to these algebras are presented. Two new pairs of lower-upper approximations of a set have been introduced in order to develop the notion of duality with respect to the quasi-complementation. Set theoretic rough set models of some of the algebras are constructed using these lower-upper approximations and quasi-complementation.

A comparison of peer change agent selection methods: Evidence from a high-school based suicide preventive intervention

BackgroundPeer-led interventions for adolescents are effective at accelerating behavioral change. The Sources of Strength suicide preventive program trains student peer change agents (peer leaders) in secondary schools to deliver prevention messaging and conduct activities that increase mental health coping mechanisms. The program currently has school staff select peer leaders. This study examined potential for more efficient program diffusion if peer leaders had been chosen under network-informed selection methods.MethodsBaseline assessments were collected from 5,746 students at 20 schools. Of these, 429 were selected by adults as peer leaders who delivered intervention content through the school year. We created theoretical alternate peer leader sets based on social network characteristics: opinion leadership, centrality metrics, and key players. Because these sets were theoretical, we examined the concordance of these sets with the actual adult-selected peer leaders sets and correlated this metric with diffusion of intervention modalities (i.e., presentation, media, communication, activity) after the first year.ResultsThe sets of adult-selected peer leaders were 13.3%—22.7% similar to theoretical sets chosen by other sociometric methods. The use of friendship network metrics produced peer leader sets that were more white and younger than the general student population; the Key Players method produced more representative peer leader sets. Peer opinion leaders were older and more white than the general population. Schools whose selected peer leaders had higher overlap with theoretical ones had greater diffusion of intervention media and peer communication.ConclusionsThe use of network information in school-based peer-led interventions can help create more systematized peer leader selection processes. To reach at-risk students, delivery of an indirect message, such as through a poster or video, may be required. A hybrid approach where a combination of visible, respected opinion leaders, along with strategically-placed key players within the network, may provide the greatest potential for intervention diffusion.

Neutron-capture elements record the ordered chemical evolution of the disc over time

ABSTRACT An ensemble of chemical abundances probing different nucleosynthetic channels can be leveraged to build a comprehensive understanding of the chemical and structural evolution of the Galaxy. Using GALAH DR3 data, we seek to trace the enrichment by the supernovae Ia, supernovae II, asymptotic giant branch stars, and neutron-star mergers and/or collapsars nucleosynthetic sources by studying the [Fe/H], [α/Fe], [Ba/Fe], and [Eu/Fe] chemical compositions of ∼50 000 red giant stars, respectively. Employing small [Fe/H]–[α/Fe] cells, which serve as an effective reference-frame of supernovae contributions, we characterize the abundance-age profiles for [Ba/Fe] and [Eu/Fe]. Our results disclose that these age–abundance relations vary across the [Fe/H]–[α/Fe] plane. Within cells, we find negative age–[Ba/Fe] relations and flat age–[Eu/Fe] relations. Across cells, we see the slope of the age–[Ba/Fe] relations evolve smoothly and the [Eu/Fe] relations vary in amplitude. We subsequently model our empirical findings in a theoretical setting using the flexible Chempy Galactic chemical evolution (GCE) code, using the mean [Fe/H], [Mg/Fe], [Ba/Fe], and age values for stellar populations binned in [Fe/H], [Mg/Fe], and age space. We find that within a one-zone framework, an ensemble of GCE model parameters vary to explain the data. Using present day orbits from Gaia EDR3 measurements we infer that the GCE model parameters, which set the observed chemical abundance distributions, vary systematically across mean orbital radii. Under our modelling assumptions, the observed chemical abundances are consistent with a small gradient in the high-mass end of the initial mass function (IMF) across the disc, where the IMF is more top heavy towards the inner disc and more bottom heavy in the outer disc.

STRESS IN RELATION TO THEORETICAL AND CLINICAL ACTIVITIES AS EXPERIENCED BY BACHELOR OF SCIENCE IN NURSING STUDENTS

Utilizing the descriptive survey method, the study aimed to determine the stress in relation to theoretical and clinical activities as experienced by Bachelor of Science in Nursing students. The specific problems were the profile of 31 student nurses, the stresses met in the theoretical and clinical setting, the coping mechanisms to the different stresses and the significant difference in coping mechanisms when grouped according to profile. The profile indicated that the student nurses have a general age of 20 years and below, dominated by female and single. The common stresses as classified: On personal stress: fear of making mistakes; academic stress: Intensity of academic workload; clinical stress: using highly technical equipment while on the time management problems, limited time to take a rest. As to the coping mechanisms, the student nurses did the following: COPING MECHANISMS INDICATORS Logical Analysis Think of different ways to deal with the problem Positive Reappraisal Tell themselves that things would get better Seeking Guidance and Support More prayers for guidance and strengths. Problem Solving Take “thinks a day at a time, one step at a time” Cognitive Avoidance They daydream or imagine a better time or place, than the one they are in. Seeking Alternative Rewards Expect the worst possible outcome Acceptance or Resignation Try to help others deal with a similar problem Emotional Discharge Cry to let their feelings out Significant differences were evident in the coping mechanisms in terms of civil status. Part of the study is the program on coping mechanisms for stress.
