Abstract:

Mathematical literacy ability is the ability to understand and to use mathematics in various contexts to solve problems and explain how mathematics can be applied in everyday life. The aim of this study was to analyze students' mathematical literacy abilities in the material for sequences and series using problem based learning (PBL). The sample of this research was class XI SMA as many as 36 students and the subject was determined using purposive sampling. Tests, interviews, and documentation were used as data collection techniques. The research instrument was in the form of a mathematical literacy ability test on sequences and series material as well as interview guidelines that had been validated thereforehe instrument being suitable for use. The results of the study showed that the application of PBL to the matter of sequences and series was able to achieve students' mathematical literacy skills. Students can solve problems systematically and correctly even though there are operations such as multiplication or addition of numbers or variables an error occurs and students from both high and low categories do not write conclusions at the end of the problem. From the ability to choose a strategy students are able to identify the information contained in the question, but not yet fully students can decide on a strategy and apply facts, operations and structures in finding solutions related to story problems on sequences and series material.

Abstract:

The article explores the characteristic categories of character descriptions that reveal the psychological and emotional propertiesof fantasy characters, their temperament, moral and ethical qualities and translation grammatical transformations used by translators to adapt works. The translation of fiction, with its descriptions and plots, is becoming quite popular and attracts the modern reader with individual features of this genre. Translators mostly use such translation transformations as the use of various paths, stylistic figures, eloquent names, means of phonetic and syntactic expression, word-formation possibilities, etc. Eachtranslator brings his own literary approach to translation and uses his favorite techniques. In fantasy works, not only the portrait characteristics of the heroes are successfully conveyed, but also the descriptions of nature, fantastic objects, clothes, food, etc. The psycho-emotional state of the hero is also successfully depicted in comparison with natural phenomena and subject features that immerse the reader in the adventure world. Such features of translation interested us in the research and prompted a comparative analysis of the original and the translation.

Methods in collecting the data was critical thinking test, namely problem solving test of linear aquation systems and interviews. This study employed triangulation by comparing the data obtained through problem solving tests and interview. The result of critical thinking through problem solving was categorized based on critical thinking stage, namely clarification, analysis and solution strategy. The results of the study reveal that at the clarification stage, the FIKT subject and FIKS subject had similarity in reading the questions briefly, understood it directly and identifying the instructions of the questions; whereas, FDKT subject and FDKS subject read the questions repeatedly and only read instruction of the questions. At the Analysis stage, FIKT subject and FIKS subject tended to be quick in abstracting and releting relevant information with supporting instruction of the questions, so it was quicker in concluding the method used to solve the problem. However, FDKT subject and FDKS subject tended to be longer in giving response, so the method used was trial and error. At the solution Strategy, FIKT subject and FIKS subject applied the method used clearly and systematically; however, FIKS subject did mistake when determining k score using determinant (for the second question), unlike FDKT subject and FDKS subject which had difficulty when making conclusions based on question instruction and FDKS subject was also made mistake when determining k score using determinant.

Abstract:

Purpose The purpose of this paper is to measure the degree of interdisciplinary collaboration in Big Data research based on the co-occurrences of subject categories using Stirling’s diversity index and specialization index. Design/methodology/approach Interdisciplinarity was measured utilizing the descriptive statistics of disciplines, network indicators showing relationships between disciplines and within individual disciplines, interdisciplinary communities, Stirling’s diversity index and specialization index, and a strategic diagram revealing the development status and trends of discipline communities. Findings Comprehensively considering all results, the degree of interdisciplinarity of Big Data research is increasing over time, particularly, after 2013. There is a high level of interdisciplinarity in Big Data research involving a large number of disciplines, but it is unbalanced in distribution. The interdisciplinary collaborations are not intensive on the whole; most disciplines are aggregated into a few distinct communities with computer science, business and economics, mathematics, and biotechnology and applied microbiology as the core. Four major discipline communities in Big Data research represent different directions with different development statuses and trends. Community 1, with computer science as the core, is the most mature and central to the whole interdisciplinary network. Accounting for all network indicators, computer science, engineering, business and economics, social sciences, and mathematics are the most important disciplines in Big Data research. Originality/value This study deepens our understanding of the degree and trend of interdisciplinary collaboration in Big Data research through a longitudinal study and quantitative measures based on two indexes. It has practical implications to study and reveal the interdisciplinary phenomenon and characteristics of related developments of a specific research area, or to conduct comparative studies between different research areas.

Abstract:

In the era of globalization we need the implementation of character education for self-limiting, given that in the era of globalization, it is difficult to recognize cultural boundaries. Therefore, it takes an integrated character education on the subjects, thus indirectly the character education has been applied. To implement an integrated character education in the subjects, required learning model that suits the character that will be applied. Team assisted individualization is one type of cooperative learning model in a way students work in cooperative learning groups and is responsible for setting and checking on a regular basis, helping each other solve problems and to encourage each other to excel. The purpose of this study is not to implement character education in mathematics using cooperative learning model Team Assisted Individualization (TAI) and know the results of students of class V SD Negeri 3 Weda. This study is a class action (Classroom Action Research) collaborative and in the form of a cycle. The subject of research is a class V SD Negeri 3 Vedas. The instrument used was a test, observation sheets, interview, and documentation. The results showed that an increase in the learning outcomes of pre-cycle where students learning completeness 0% increase in the first cycle to the second cycle of 40% and 76%. The same thing can be seen in the ability of teachers to manage the classroom, in the first cycle teachers value increased in the second cycle of 3.75 to 4.58 with both categories. For the implementation of the integrated character education in mathematics can be seen in the first cycle of 98.67% the percentage of character discipline, teamwork 96%, and the responsibilities of 86.71%. In the second cycle, 98.76% of students have had the character of discipline, 96.90% students have the character of cooperation, and 88.89% of students have had the character of responsibility.

Abstract:

As an emerging research direction in the field of systems and control, distributed control or decentralized control has attracted great interests of researchers in the past decade. In this paper, a bibliometric analysis of the relevant publications is presented based on the data collected from the Science Citation Index Expanded Web of Science. In particular, we make a discussion on the trend of total publications, journal distribution, top research organizations (i.e. universities and institutes), and publication performance of nations, and the focus is on highly cited articles and authors, subject categories, and the future trend of hot topics. Some key bibliometric indexes such as single country articles, first author articles, and internationally collaborative articles are employed to give us a detailed picture about the intrinsic relationship and the state of the art of distributed control publications. Finally, the statistical analysis indicates that multi-agent systems are extremely popular in recent years and will dominate the future research on distributed control.

Abstract:

The problems of adaptation of the state, citizens, organizations to the realities of the digital economy of Russia and the world reveal a number of tasks that require study and search for solutions. The results of the digital economy, depending on its subject, can be different: for the state, it is the improvement of legislation and control over its implementation; for citizens – the availability, reliability of information, as well as the availability of goods and services of appropriate quality; for businesses – strengthening competitive advantages with the use of IT; for innovators promoting the ideas of the digital economy – the implementation of IT solutions in practice, etc. Process management implemented in organizations also requires rethinking in order to digitalize business processes and “embed” enterprises into the digital economic environment of the state and the world. The digitalization of the personnel management sphere requires a revision of the functions of the personnel management system in order to develop and apply new tools in the HR industry, which will make it possible to implement the digitalization of the personnel management system. In the context of the digitalization of society, digital skills and digital competencies have become in demand, the basis of which is information literacy: the ability to work effectively in search engines, knowledge of search operators, the skill to quickly find the necessary information in authoritative sources; the skill of collecting relevant data and conducting research based on large amounts of digital data. The presentation of the skills of a modern employee in the form of such categories as Hard-skills, Soft-skills, Digital-skills, Power-skills is the basis for the implementation of the competence-based approach at the stages of human resource development in an organization that implements the functions of personnel management in the context of the development of the digital economy.

Abstract:

The main thesis of the proposed research is that in modern conditions of globalization, the realization of the right of citizens to education is an important and necessary condition for the development of society and the state. The right to education provides everyone with knowledge, skills, the development of creative abilities, guarantees the effective functioning of state and public institutions, national security, maintains stability in society and contributes to the development of a democratic, social rule of law state. The purpose of the study is to develop a holistic concept of constitutional and legal provision of the right to education in the Republic of Kazakhstan, taking into account international experience and developing proposals for improving domestic legislation regulating the right to education. The methodological basis is a system of philosophical and ideological approaches, principles, general scientific and special scientific methods that provided an objective analysis of the subject of research. The article substantiates that the state is also interested in ensuring the right to education for everyone, since it is education that creates qualified labor potential, provides training for professional specialists capable of effectively managing public affairs and performing its tasks. In turn, as a rule, an increase in the educational and qualification level of a person is the basis for salary growth, which affects the increase in tax deductions to the state budget, its filling, and therefore leads to economic growth of the state and society as a whole. The effective functioning of the education system in the state contributes to reducing unemployment (pupils, students belong to the category of the employed population), ensuring the vital activity of state institutions, national security, building a social state and establishing stability in society. Special attention in this article is paid to the implementation of scientific analysis of the right to education in the Republic of Kazakhstan in the context of modern international experience. The article makes a number of new theoretical conclusions and proposals, in particular: the signs of the right to education are classified into general (inherent in all categories of human and civil rights) and special (reveal the peculiarity of the right to education in the system of constitutional rights); the concept and content of the principles of the right to education are defined, what are the fundamental principles, ideas that determine its essence and the general direction of development.

Abstract:

SynopsisWhile studies from diverse fields of research suggest a relationship between problems expressing anger and cardiovascular illness, few studies have provided a potential pathophysiological link of such a relationship. Forty-five males were classified according to one of three anger expression categories: those who did not suppress their anger (N = 13), those who partially suppressed their anger (N = 19), and those who definitely suppressed their anger (N = 13). For each, we determined lymphocyte β-adrenergic receptor function and blood pressure responsiveness to a standardized mathematics stressor. Those subjects who routinely suppressed their expression of anger had increased β-adrenergic receptor sensitivity (P = 0·01) (isoproterenol-stimulated cyclic AMP production) and a greater systolic blood pressure response to the stressor (P = 0·001). Anger suppression was unrelated to the subject's age, weight, or socioeconomic status. These findings may be germane to prior clinical and epidemiologic observations relating anger expression and cardiovascular illness.

Abstract:

The article is devoted to the theoretical foundations of serviceology at hotel and restaurant enterprises, as a science of economic development and management in the field of service. The object of the article is the sphere of service as a structural element of the modern global economy. The purpose of this article is the development of service science at hotel and restaurant enterprises, as a scientific basis for the development of the service sector in the modern economy of the country. To achieve the goal, the following tasks are solved:- the concept and categories of serviceology in the sphere of services at hotel and restaurant enterprises and the impact of scientific, technical and socio-economic progress on it are investigated;- given characteristics of the position of serviceology – the science of the service sphere and its development;- consider the roles and laws to improve the quality of services and the efficiency of management of the sphere of services in the conditions of scientific and technical progress and intensive development of information technologies.The research methodology in this article includes historical and logical analysis, structural analysis, comparative analysis, analogy, scientific synthesis.The scientific novelty of the article lies in the fact that the provisions of serviceology are being formed at the enterprises of the hotel and restaurant business, as the scientific basis of the service sphere. The theoretical foundations of the development of the economy and management in the field of service at hotel and restaurant enterprises in the conditions of globalization of the service market, the development of service and information technologies and communications, which can be used to analyze the competitiveness of services at hotel and restaurant enterprises, are studied and formed.In the integration of types of services, such as tourism, hotel, museum business (and others), the restaurant service can increase the quality and attractiveness of such services by creating a synergistic effect of obtaining cognitive, cultural and food satisfaction. The subject of hotel and restaurant serviceology can be called the system of economic, managerial, organizational, financial, social relations that arise in the process of promotion, production and consumption of hotel and restaurant services.Subjects of the sphere of hotel and restaurant services are producers, consumers, customers, intermediaries (individuals and legal entities) participating in the process of socio-economic relations in the sphere of production and consumption of hotel and restaurant services.Hotel and restaurant serviceology can be a part, a structural element of modern serviceology, science and science.Therefore, the development of a conceptual apparatus and science about this segment of social services is needed. We will take into account that the term serviceology is a combination of the words «service» and «logos (science)», and the definition «hotel-restaurant» emphasizes branch affiliation and the specificity of the branch. In addition, let's pay attention to the fact that the concept of restaurantology is derived from the words «restaurant» and «logos (science)» and also indicates a scientific character, industry focus and social orientation. Thus, at the conceptual level, it is emphasized that the hotel and restaurant business simultaneously acts as a part of serviceology and the science of hotels and restaurants, their functioning and socio-economic significance. Keywords: service, service activity, hotel-restaurant state, efficiency, effectiveness, rational achievement.

Abstract:

With the rapid development of the Internet, various forms of network attack have emerged, so how to detect abnormal behavior effectively and to recognize their attack categories accurately have become an important research subject in the field of cyberspace security. Recently, many hot machine learning-based approaches are applied in the Intrusion Detection System (IDS) to construct a data-driven model. The methods are beneficial to reduce the time and cost of manual detection. However, the real-time network data contain an ocean of redundant terms and noises, and some existing intrusion detection technologies have lower accuracy and inadequate ability of feature extraction. In order to solve the above problems, this paper proposes an intrusion detection method based on the Decision Tree-Recursive Feature Elimination (DT-RFE) feature in ensemble learning. We firstly propose a data processing method by the Decision Tree-Based Recursive Elimination Algorithm to select features and to reduce the feature dimension. This method eliminates the redundant and uncorrelated data from the dataset to achieve better resource utilization and to reduce time complexity. In this paper, we use the Stacking ensemble learning algorithm by combining Decision Tree (DT) with Recursive Feature Elimination (RFE) methods. Finally, a series of comparison experiments by cross-validation on the KDD CUP 99 and NSL-KDD datasets indicate that the DT-RFE and Stacking-based approach can better improve the performance of the IDS, and the accuracy for all kinds of features is higher than 99%, except in the case of U2R accuracy, which is 98%.

Abstract:

The main factors influencing the choice of individual subjects of the scientific activity or potential partners and executors for scientific and educational projects were analyzed. The specific features of choosing project executors of different categories were indicated. The functional responsibilities of project participants in accordance with the project structure were described. The individually oriented method for choosing subjects of scientific activity as executors of scientific and educational projects was developed, taking into account the productivity of their scientific activities in the past and considering the structure of projects. To determine the merits of the subjects of scientific activity, which are included in the relevant scientific subject spaces, it is necessary to apply the procedure of their productivity assessment. In addition, it is necessary to predict a change in productivity in the future based on retrospective data for this subject. Next, it is required to solve the multi-criteria problem of the choice among the subjects of scientific activity who are quite productive in the opinion of the project manager. The use of the developed method reduces the subjective impact on making a decision regarding the choice of project executors. This is due to the fact that they are chosen by automated calculation of scientometric indicators of subjects, guided only by open sources of information. The individually oriented method for the selection of subjects of scientific activity was verified on the example of the formation of three applications of research projects. As a result, the average percentage of scientists who meet the requirements of project managers for each scientific subject space was about 46.55 %. The percentage of those involved in the project from those who were selected is about 24.07 %. The probability of cooperation is higher among those who have an average H-index.

Abstract:

In order to closely fit the characteristics of continuing education, the development of continuing education teaching activities under the network background should not only be combined with the characteristics of professional adult education but also make reasonable use of modern teaching models in the actual teaching process. Based on the community detection algorithm in complex networks, this article makes thorough research and analysis on the complexity of Chinese continuing education by using complex network technology. By establishing the characteristics of vertex degree distribution, average path length, and clustering coefficient of complex networks, it is confirmed that Chinese continuing education has scale-free network characteristics and small-world network characteristics. The three aspects of relationship strength comprehensively analyze the information dissemination speed, scope, interpretation, and application; through the combination of the ant colony algorithm and complex network technology, multiple information dissemination paths are abstracted in Chinese continuing education. The research shows that the application of complex network algorithms can effectively improve the speed and quality of continuing education in China. It is found that the government should increase the number of adult education projects and improve the level of project categories, form key adult education research basis to promote the diversification of research subjects, expand the space for adult education projects to balance regional and provincial differences and attach importance to basic research on adult education, and integrate applied research.

Abstract:

The study investigated the reported regressive performances of students in spatial reasoning concepts with a view to promote early spatial reasoning of lower primary school pupils across ability levels and sex. Non-equivalent experimental research design was employed. A hundred and five (105) pupils in four intact classes were exposed to six weeks intervention and subsequently post-tested. Data collected were analyzed using Analysis of Covariance. The study found significant effect of treatment on the performance of study participants in the ICT-integrated Think-Pair-Share treatment group. No significant interactive effect of ability was found though, the pupils of low-ability group benefitted more from the intervention (M = 12.32, 11.07; SD = 2.86, 2.98). There was no significant different of intervention between boys and girls across strategies and abilities. The study concluded that, while ICT-integrated learning strategies could improve output in spatial concepts of pupils at the primary school level, performances on the basis of sex-groups and ability groups have no significant interaction effect on the learners of spatial reasoning. Keywords: performance, spatial reasoning, treatment, strategies, ability group, think-pair-share, concrete-representation-abstract, learners’-self-controlled.INTRODUCTIONEarly graft of mathematic ability has been ascertained to predict later mathematical achievement and related endeavors in life [6]. Hence, the promotion of early mathematic competency is of critical importance. Established link between spatial ability and mathematics in early childhood by neuropsychological and brain imaging studies and behavioral evidences potent that math performance can be improved with spatial reasoning. Nigeria’s experience in local, national and international examinations show dwindling performances of examinees traceable to substantiated inefficient score in spatial reasoning items consistently featured [5, 1] in such standardized examinations. This was interpreted to mean that, children understanding of space pattern is necessary and demanded by the curriculum. The advent of information and communication technology (ICT) eulogized as potentially powerful and enabling tool for education change and reform is hereby engaged in learning delivery for comparative analysis of performance in learning spatial concepts among primary school pupils. METHODOLOGYNon-equivalent pretest, posttest and control group research design was adopted. The population consisted of 357,533 pupils’ enrolled in 1, 378 primary schools in Osun State (Daily Independent, 2013) characterized with male and female learners of varied academic abilities. Study sample was eked out using purposive and multi-stage sampling techniques. Primary III class was purposively selected based on the learners' age (6 – 8 years) limit in early childhood. Four schools with 105 intact class pupils were multi-stage sampled in the three major towns of the state considering available facilities for the study. Research instruments included Spatial Reasoning for Children (SpatReC), an interactive, multimedia package designed using C-Sharp (C#) programming language and follows the taxonomy based on Benjamin Blooms’ principles as revised by Anderson and Krathwohl in [8]; and Spatial Reasoning Test (SRT) used for pretest and posttest. Instruments, in a previous study [1] were adjudged validity and reliable. Learners in their intact classes were randomly assigned to study conditions namely; the three experimental groups and the one control group; three levels of cognitive ability groups - high, medium and low; and two sex groups - male and female. The intervention took forty minutes of Mathematics periods for three days in a week and six weeks in each of the schools excluding tests. ANALYSIS:Tests for significant interaction effect of treatment on groups were conducted. Result shows the test of equality of means to be significantly equal (t = 2.003, p - 0.05) in favor of equal variance assumed. The study’s subjects were thus adjudged to be reliably homogeneous (Table 1).Table 1: Test for Difference in the Participating group’s Post-test Scorest-test for Equality of MeanstdfSig.(2-tailed)Mean DifferenceStd. Error Difference95% Confidence Interval of the DifferenceLowerUpperEqual variances assumed2.003103.0481.253.626.0122.494Furthermore, the post-test scores of the research participants were subjected to a test of difference via analysis of covariance using their experimental groups as the differentiating variable and the pre-test scores as the covariate to remove the possible effect of previous learning and other confounds. The result showed significant difference in the post-test scores (F = 2.934, p - .05). It also showed from the table that, the R-squared value was 0.080 and the Adjusted R squared value stood at 0.053. This can be interpreted to mean that the maximum variance in the post test score is quite small. So other possible factors which might explain the difference in the post test scores and interact with the effectiveness of the learning strategies were sought after (Table 2).Table 2:Post-Test of Difference of Treatments Tests of Between-Subjects Effects - Dependent Variable: post test scoreSourceType III Sumof SquaresDfMean SquareFSig.Corrected Model96.677a332.2262.934.037Intercept34388.204134388.2043131.034.000GRP96.677332.2262.934.037R Squared = .080 (Adjusted R Squared = .053)The source of difference was located between the CRTL group and the CRA group (Table 3). It can be concluded that there exists significant difference among the learning strategies in improving performances.Table 3: Multiple Comparisons Post hoc TestDependent Variable: post-test score Tukey HSD(I) Treatment(J) TreatmentMean Difference(I-J)Std.

To answer this question, the post-test scores of the research participants were subjected to a test of difference via analysis of covariance. Result shown in Table 4 revealed that there is no significant interaction effect of experimental groupings and ability levels on the post-test scores (F = 1.440, p > .05). In this stance therefore, the research question is answerable in the negative.Table 4: Test of Difference of Treatment and Ability in Post-test Tests of Between-Subjects Effects Dependent Variable: post test scoreSourceType III Sum of SquaresDfMean SquareFSig.Corrected Model113.502a716.2151.440.198Intercept28102.188128102.1882495.206.000GRP * ability113.502716.2151.440.198a.

Despite the slight differences in group sizes, no significant difference in the performance on the basis of sex-groups (value = 0.186, > 0.05) was found. It as well showed that, there was no significant interaction found between groups and sex in describing performance of pupils in spatial reasoning (F = 0.030, p > 0.05) (Table5).Table 5: Test of Difference on Post-test in Treatment / Sex Groups DescriptivePost test scoreNMeanStd.

Notable results included significant effect of treatment on performance at the removal of possible effect of previous learning and other confounds. This discovery agrees with [3] whose study established that particular intervention in the experimental group might increase learner’s motivation and in turn lead to higher achievement levels for learners in the experimental group than for those in the control group. [2, 4] also found particular learning strategies - conceptual learning strategy and online tool substantially increasing math performance growth in separate studies. Ability levels’ effect on academic achievement as investigated indicated no significance in the post-test scores even after controlling for the previous learning through the pre-test. This result was at variance to [7] study on game-based learning (GBL) which found that, many students with low confidence toward learning mathematics can be restored and improve their confidence toward mathematics. Conclusively, performances on the basis of sex-groups and ability groups have no significant interaction found between ICT-integrated strategy learners of spatial reasoning. REFERENCES Adeleke, A. G.

Abstract:

As discussões referentes a novas estratégias de ensino, que facilitem o acesso aos conteúdos que têm apresentado baixos índices de aprendizagem, têm permeado pesquisas no campo educacional, principalmente no tocante ao componente curricular matemática e, de forma particular, ao assunto progressões aritméticas. Esse objeto de conhecimento tem revelado, no contexto das metodologias convencionais de ensino, obstáculos epistemológicos de difícil transposição. Nesse contexto, objetiva-se apresentar uma proposta metodológica denominada Situação Didática Olímpica (SDO) aplicada ao ensino das progressões aritméticas de segunda ordem. Consubstanciada no contexto das Teoria das Situações Didáticas (TSD), a (SDO) está alicerçada na Engenharia Didática (ED) como metodologia de pesquisa. Dessa forma, visando revelar aspectos subjetivos do objeto analisado, essa pesquisa é de cunho qualitativo e de caráter exploratório. A proposta de aplicação desenvolvida neste trabalho consiste na proposição de um problema da Olimpíada Brasileira de Matemática das Escolas Públicas (OBMEP), Nível III, envolvendo números figurais (triangulares) direcionado a alunos do ensino médio de escolas públicas. Na transposição didática será utilizado, como artefato tecnológico, o software GeoGebra, que é o ambiente onde a SDO é modelada aliado à Teoria dos Registros de Representação Semiótica (TRRS) de Duval. A SDO, como proposta metodológica, visa a mobilização das categorias intuitivas do raciocínio, proporcionando maior autonomia aos alunos, visto que o professor atua como mediador nas situações didáticas elaboradas. Considera-se com essa proposta de ensino, revelar aspectos presentes nas narrativas dinâmicas proporcionadas pelo referido software à luz da TRRS, objetivando ampliar o campo de ação docente nesse componente curricular, buscando para além da melhoria nos seus índices de proficiência, o fomento a pesquisas futuras no contexto da inovação educacional. Palavras-chave: SDO. Progressões Aritméticas. GeoGebra. Engenharia Didática. AbstractThe discussions refer to new teaching strategies, which facilitate access to contents that present low learning rates, have permeated research in the educational field, mainly with regard to the curricular mathematics component and, in particular, to the subject of arithmetic progressions. This object of knowledge has revealed, in the context of conventional teaching methodologies, epistemological obstacles that are difficult to overcome. In this context, the objective is to present a methodological proposal called the Olympic Didactic Situation (SDO) applied to the teaching of second-order arithmetic progressions. Embodied in the context of the Theory of Didactic Situations (TSD), the (SDO) is based on Didactic Engineering (ED) as a research methodology. Thus, seeking to reveal subjective aspects of the analyzed object, this research is qualitative and exploratory in nature. The application proposal developed in this work consists of proposing a problem of the Brazilian Mathematical Olympiad for Public Schools (OBMEP), Level III, involving figural (triangular) numbers aimed at high school students from public schools. In the didactic transposition, GeoGebra software will be used as a technological technology, which is the environment where the SDO is modeled, combined with Duval's Theory of Semiotic Representation Registers (TRRS). The SDO, as a methodological proposal, aims at monitoring the intuitive categories of thought, providing greater autonomy to students, since the teacher acts as a mediator in the elaborated didactic situations. With this teaching proposal, it is considered to reveal aspects present in the dynamic narratives provided by the referred software in the light of the TRRS, aiming to expand the teaching field of action in this curricular component, seeking, in addition to improving their proficiency rates, the promotion of research future in the context of educational innovation. Keywords: SDO. Arithmetic Progressions. GeoGebra. Didactic Engineering.

Abstract:

The article aims at discussing the XIX century’s European studies which influenced the new ethically-themed performance, viewed as the source of the main meaningful (or subject-to-subject) cultural categories. Social and scientific changes, which led to the “cultural upheaval”, made the scientists consider the value system newly and define the existence of the dynamic cultural-ethic elements as a system. Further this approach provided the basis for the division of the cultural categories into fundamental and meaningful. The vectors of ethic norms’ transformation are also under discussion, i.e. the development of philosophical ideas of the following researchers A. Schopenhauer, F. Nietzsche, Ch. Darwin, A. Bergson: voluntaristic (built on the philosophy of the will), evolutionist (based on the Ch. Darwin’s theory of biological evolution) and vital (designed on the metaphysics of Bergson’s Elan Vital). Viewed as a whole, both “philosophy of living” and Ch. Darwin’s theory of the origin of species seem to ground cultural categories of a moral and ethical value. Thanks to them, life turned out to be not only of irrational creative philosophical principle but also of the ultimate value; while the concept struggle for existence moved to Biology. Life as an ultimate value acknowledgment did not mean the full refusal from the morality with the social degradation, it was only associated with relativization of traditional (Christian, primarily) values. This acknowledgment did not involve the recognition of the human being’s unlimited selfishness which in practice had to give way to the “instinct” of solidarity found in animality.

Abstract:

Purpose of the work is to create a theoretical model of the thinking process, considered as a set of operations for the formation of cognitive generalizations of the level of categories (concepts). Method for creating a theoretical model is based on the approach used in natural sciences. It involves the selection of a small number of reliable facts, which are accepted as true on the basis of their evidence. On the basis of these facts, established in various scientific disciplines, the axioms of the proposed theory are formulated. Further, from the accepted axioms, they are logically deduced in the form of consequences: a) already known results that could be obtained in various fields of science, including those differing in the content of research, and therefore previously perceived as not related to each other; b) predictions of new connections and patterns in the study area. Results of the work are that it was possible to propose a version of the postulate dynamic theory of thinking, in which the main variables are the number of concepts formed, lost, realized and unconscious by the subject. The introduced postulates and variables made it possible to consider two types of models at the moment. Balanced integrodifferential models that describe the accumulation of the volume of conscious and unconscious concepts, as well as combinatorial models that describe the interactions of concepts. Conclusion. The proposed version of the dynamic thinking model made it possible to construct reasonable theoretical descriptions of the process of spontaneous language acquisition by bilingual children in a bilingual environment and a person’s ability to compare semantically heterogeneous objects with each other. The logical scheme of the approach and the concepts used in it made it possible to connect some facts known in psychology and in an explicitly compact formulation of the difference in the structure of scientific and artistic generalizations of the picture of the world.

Abstract:

Neuromarketing is a multidisciplinary field of research whose aim is to investigate the consumers’ reaction to advertisements from a neuroscientific perspective. In particular, the neuroscience field is thought to be able to reveal information about consumer preferences which are unobtainable through conventional methods, including submitting questionnaires to large samples of consumers or performing psychological personal or group interviews. In this scenario, we performed an experiment in order to investigate cognitive and emotional changes of cerebral activity evaluated by neurophysiologic indices during the observation of TV commercials. In particular, we recorded the electroencephalographic (EEG), galvanic skin response (GSR), and heart rate (HR) in a group of 28 healthy subjects during the observation of a series of TV advertisements that have been grouped by commercial categories. Comparisons of cerebral indices have been performed to highlight gender differences between commercial categories and scenes of interest of two specific commercials. Findings show how EEG methodologies, along with the measurements of autonomic variables, could be used to obtain hidden information to marketers not obtainable otherwise. Most importantly, it was suggested how these tools could help to analyse the perception of TV advertisements and differentiate their production according to the consumer’s gender.

Abstract:

Objectives. Fatty liver disease (FLD) is strongly linked to the occurrence of type 2 diabetes mellitus (T2DM). Insulin resistance (IR) is linked to smoking. Our study’s purpose was to see how smoking and fatty liver accompanied affected the development of T2DM in the past. Materials and Methods. We collected data from 15,464 Japanese adults aged 18 to 79 years who took part in the NAGALA research, and our team utilized a Cox proportion risk model to look at the combination effect of FLD and smoking status on the incidence of T2DM. Participants were separated into three categories: nonsmokers, ex-smokers, and current smokers. An abdominal ultrasound was used to diagnose FLD. Results. 384 subjects had T2DM after a median follow-up of 5.4 years. In comparison to the other groups, current FLD smokers had a greater chance of developing T2DM. Ex-smokers and present FLD smokers, on the other hand, had no significant difference in their likelihood of acquiring T2DM. When compared to ex-smokers and nonsmokers without FLD, current smokers with FLD had a considerably greater chance of acquiring T2DM. Furthermore, the risk of T2DM among nonsmokers, ex-smokers with FLD, and current smokers without FLD was not statistically significant. Conclusions. In order to prevent the progression of T2DM, we should recognize that smoking status may vary in FLD.

Abstract In this paper, we discuss the generalization of finitary 2-representation theory of finitary 2-categories to finitary birepresentation theory of finitary bicategories. In previous papers on the subject, the classification of simple transitive 2-representations of a given 2-category was reduced to that for certain subquotients. These reduction results were all formulated as bijections between equivalence classes of 2-representations. In this paper, we generalize them to biequivalences between certain 2-categories of birepresentations. Furthermore, we prove an analog of the double centralizer theorem in finitary birepresentation theory.

Abstract:

The subject of the research is the phenomenon of dissipation of the social identity of young people in modern Russian society. Purpose: to compare the reflection of this phenomenon in the academic and public consciousness. Hypothesis: the dynamics and structure of the idea of the social identity of young people at the present stage of Russia's development is not the same in the academic and public consciousness. The hypothesis was tested on the example of publications included in the RSCI database. There are two categories of publications: 1) scientific journals, dissertations, 2) conference materials. The first reflects ideas about social phenomena in the minds of the academic community; the second is in the mass consciousness of the general scientific community. Search depth 11 years (2012–2021). It included the annexation of Crimea to Russia, pension reform, the C0VID-19 pandemic, and the merger of two social support funds for the population (PF and FSS). The volume of empirical data amounted to 86341 titles of publications. The views of the authors of publications on the phenomenon under study were recorded according to five search queries: “social identity of young people”, “social security”, “social protection”, “social assistance”, “social support”. The algorithm of the relationship between these topics was studied using paired correlation analysis. It was found that the peak of publications for these requests coincided with the three-year period 2016–2018. The reflection of the problem of the social identity of young people in academic publications preceded its active discussion in conference proceedings by 4–6 years. Fundamental differences are found in the ideas about the social identity of young people in the academic and public consciousness. In scientific articles and dissertations, the social identity of young people is considered as a special case of self-organization of complex social systems, in conference materials – as a separate element of a hierarchically built deterministic financial system. The results obtained are regarded by us as proof of the correctness of the null hypothesis put forward. Possible areas of application of the results of the study: youth, social and demographic policy of the state at a new stage of socio-economic reforms. The limitation for the implementation of the research results in the practice of social management may be the effect of inertial public opinion and mass consciousness, as well as the financial interests of individual lobbies currently involved in the implementation of social projects. Directions for future research – targeted monitoring of the transformation of the mass in accordance with the requirements of the modern technological revolution.

Abstract:

The current study employed a content analysis approach to analyze and compare argumentation research in K-12 mathematics and science education published on top five academic journals with the highest impact factor from 2010 to 2019. It includes 9 research articles in the field of mathematics education and 77 research articles in the field of science education. The objectives of this study are to examine the similarities and differences in number of articles, contributors by nationality, method and design, subject, model, setting, and research topics. The results show that despite the argumentation research trend in both contexts tends to decrease, there are more researches related to argumentation on science subject compared to mathematics at K-12 level. These results have an impact on the increasingly diverse categories of argumentation studies in K-12 science. The implications of this research can obviously provide insights to the study of argumentation for mathematics education, science, and education researchers.

Abstract:

The purpose of this study was to describe the classification of students' reasoning abilities in solving mathematical problems in elementary schools. The focus of this study is the classification of students' reasoning abilities in solving mathematical problems in the elementary schools of the city of Semarang. This study uses a qualitative approach. The Research subject is elementary school students at Tambakrejo Elementary School Semarang. Data is taken using tests. Based on data analysis, the reasoning classification is as follows: 36.25% understand the meaning in low categories, 37.5% think logically in low categories, 31.1% understand negative examples in low categories, 17.05% think deductions in very low category, 18.15% think systematically in very low categories, 31.65% think consistently in low category, 34.85% make excuses and determine strategies in low category, 49.85% determine method in low category, and 24.3% draw conclusions in low category. Thus the reasoning ability of students is low, students have not been able to think logically to make connections between empirical facts and the problems faced so they are not able to draw conclusions, students have not been able to do the thinking process to make arguments so that new statements are based on facts, it is necessary to develop learning models to improve mathematical reasoning of elementary school students
