Abstract:

High training intensity, volume, and academic demands have negatively affected young athletes' academic achievements. This study is written to determine the differences in the effects of long-term athlete development-based football training on football players' physical abilities and academic achievements aged 10 and 12 years. Forty-four young football players were involved in this study divided into two age groups of 10 (n = 21) and 12 (n = 23). Before and after the six-month and one-year treatment, physical abilities, consisting of 30 m sprint ability and leg muscle explosive power, were measured using a vertical jump test and aerobic endurance with a multistage fitness test (MFT). In contrast, academic achievement was measured by documenting the scores of mathematics, language, science, social sciences in the report book. The results showed that the long term athlete development-football training model impacted physical abilities but did not affect academic achievements. There was no significant difference between groups of ages 10 and 12. Long-term athlete development-based football training can develop physical abilities and support young football players to complete academic activities.

Abstract:

The language of teaching and learning challenges Physical Sciences teachers and impacts learners’ achievements. The study aimed to investigate how language literacy is integrated into the teaching of Physical Sciences. A descriptive survey design was adopted. The participants were five Grade 10 Physical Sciences teachers and 211 learners (108 boys; 103 girls) from nine schools exhibiting low academic achievements. Data were gleaned through the Literacy Skills Usage Survey Questionnaire (LSUSQ). The results show that 77.78% of the teachers did not engage learners in report writing and arguments which are fundamental to language literacy, suggesting that integrating literacy in science teaching was inadequate. Learners had difficulties in contributing to word walls, writing reports, and arguing from evidence. The lack of integration suggests that teachers lacked training in integrating language literacy into science teaching. These findings underscore the need for workshops to enable teachers to incorporate language literacy in teaching Physical Sciences. Keywords: arguing from evidence, integrate, language literacy, reading and report writing

Abstract:

The father of instrumental microanalysis, Raymond Castaing, died on April 10, 1998. With him, we lost one of the outstanding figures in modern materials characterization. He was creative and innovative in physical research, in invention of instruments, in teaching, and in science management. At a time when science tends toward an inexorable division into smaller and more specialized provinces, an investigator of truly wide-ranging interests and capabilities, in the best traditions of renaissance curiosity, has left us.

Abstract:

This research was aimed at studying the content of academic gender stereotypes of pre-service teachers who are being prepared for working in different cycles of education. The sample included 408 students of teaching programmes of the Teacher Training College, Faculty of Mathematics and Faculty of Philology in Belgrade. It has been established that future class and subject teachers have gender stereotypes about the interests and achievements of students in different school subjects. pre-service teachers from both groups are of the opinion that girls get interested more easily than boys in the majority of school subjects, as well as that girls are more talented for the subjects in the field of humanities and languages, while boys are more talented for the subjects in the field of sciences. Pre-service teachers estimate that boys typically have a low achievement in languages, arts and music, while girls have a low achievement in physics, computer science, technical sciences and physical education. Since teachers? gender stereotypes can affect students? achievement, educational and career choices, it is important to raise awareness about the content and consequences of such beliefs in teachers and focus on certain actions towards their altering.

Abstract:

Application of new achievements in science and technology to the physics laboratory sessions can ensure the advancement of physics education. One particular example of the technologies giving new opportunities in the design of physics laboratory works is the magnetic fluid. We describe the laboratory works within the scope of the general physic course for the undergraduate students. Principal feature of the laboratories presented is the use of magnetic fluids. It makes possible to design some creative laboratory works, which can help to develop skills in performing scientific experiments and to increase the understanding of the physical concepts. The sample consists of 120 third-grade university students from the Department of General and Theoretical Physics in the North Caucasus Federal University in Stavropol, Russia. These laboratories arouse students’ interest and contribute to the achievement of high quality of learning outcomes. We also show that such laboratories engage students’ interest in the scientific research work.

Abstract:

The urgency of conducting research in the field of quantum informatics is grounded. Promising areas of research are highlighted. For foreign and Russian publications and materials, a review of the main scientific results that characterize the current state of research in quantum computer science is made. It is noted that knowledge and funds are invested most intensively in the development of the architecture of a quantum computer and its elements. Despite the fact that today there is no information on the creation of a physical implementation of a quantum computer comparable in functionality to a classical digital computer, the development of quantum algorithms is one of the popular areas of research. An advantage of quantum algorithms is the fact that they reduce the time required to solve the problem due to the parallelization of operations by generating entangled quantum states and their subsequent use. This advantage (quantum acceleration) is most important when solving the problem of modeling the dynamics of complex systems and enumerated mathematical problems. (The general case of enumeration is the Grover scheme and its variants; the tasks of searching for hidden periods: Shor's scheme of using the fast quantum Fourier transform and its analogues.) The demand for cybersecurity developments (search for vulnerabilities in smart spaces, secure storage and use of big data, quantum cryptography) is noted. More than a dozen articles are devoted to quantum algorithms of key search, key distribution on optical fibers of various lengths, and the analysis of quantum resources necessary for conducting a cyber attack. In the field of artificial quantum intelligence, attention is paid, first of all, to the “search” for a model of a quantum neural network that is optimal from the point of view of using all the advantages presented by quantum computing and neural networks, as well as machine learning algorithms. Examples of the use of quantum computing in cognitive and social sciences for studying the decision-making mechanism with incomplete data are given. It is concluded that quantum informatics is promising for the simulation of complex natural and artificial phenomena and processes.

Abstract:

Purpose:To examine the impact of integrating physical activity with elementary curricula on fluid intelligence and academic achievement.Methods:A random sample of 3rd grade teachers integrated physical activity into their core curricula approximately 30 minutes a day, 3 days a week from January 2008 to April 2008. Noninvasive fluid intelligence cognitive measures were used along with State-mandated academic achievement tests.Results:Experimental Group children averaged close to 1200 pedometer steps per integration day, thus averaging 3600 steps per week. Children in the Experimental Group performed significantly better on the SPM Fluid Intelligence Test. Children in the Experimental Group also performed significantly better on the Social Studies State mandated academic achievement test. Experimental Group children also received higher scores on the English/Language Arts, Math and Science achievements tests, but were not statistically significant compared with Control Group children. Children classified in Fitnessgram’s Healthy Fitness Zone for BMI earned lower scores on many of the SPM Fluid Intelligence components.Discussion:This investigation provides evidence that movement can influence fluid intelligence and should be considered to promote cognitive development of elementary-age children. Equally compelling were the differences in SPM Fluid Intelligence Test scores for children who were distinguished by Fitnessgram’s BMI cut points.

Abstract:

For the last two decades, titanium dioxide (TiO2) has received wide attention in several areas such as in medicine, sensor technology and solar cell industries. TiO2-based gas sensors have attracted significant attention in past decades due to their excellent physical/chemical properties, low cost and high abundance on Earth. In recent years, more and more efforts have been invested for the further improvement in sensing properties of TiO2 by implementing new strategies such as growth of TiO2 in different morphologies. Indeed, in the last five to seven years, 1D nanostructures and heterostructures of TiO2 have been synthesized using different growth techniques and integrated in chemical/gas sensing. Thus, in this review article, we briefly summarize the most important contributions by different researchers within the last five to seven years in fabrication of 1D nanostructures of TiO2-based chemical/gas sensors and the different strategies applied for the improvements of their performances. Moreover, the crystal structure of TiO2, different fabrication techniques used for the growth of TiO2-based 1D nanostructures, their chemical sensing mechanism and sensing performances towards reducing and oxidizing gases have been discussed in detail.

Abstract:

BIO2010 advocates enhancing the interdisciplinary, mathematics, and physical science components of the undergraduate biology curriculum. The Department of Chemistry and Life Science at West Point responded by developing a required physical chemistry course tailored to the interests of life science majors. To overcome student resistance to physical chemistry, students were enabled as long-term stakeholders who would shape the syllabus by selecting life science topics of interest to them. The initial 2 yr of assessment indicates that students have a positive view of the course, feel they have succeeded in achieving course outcome goals, and that the course is relevant to their professional future. Instructor assessment of student outcome goal achievement via performance on exams and labs is comparable to that of students in traditional physical chemistry courses. Perhaps more noteworthy, both student and instructor assessment indicate positive trends from year 1 to year 2, presumably due to the student stakeholder effect.

Abstract:

Learning has been a significant emerging field for several decades since it is a great determinant of the world’s civilization and evolution, having a significant impact on both individuals and communities. In general, improving the existing learning activities has a great influence on the global literacy rates. The assessment technique is one of the most important activities in education since it is the major method for evaluating students during their studies. In the new era of higher education, it is clearly stipulated that the administration of higher education should develop an intelligent diversified teaching evaluation model which can assist the performance of students’ physical education activities and grades and pay attention to the development of students’ personalities and potential. Keeping the importance of an intelligent model for physical education, this paper uses factor analysis and an improved random forest algorithm to reduce the dimensions of students’ multidisciplinary achievements in physical education into a few typical factors which help to improve the performance of the students. According to the scores of students at each factor level, the proposed system can more comprehensively evaluate the students’ achievements. In the empirical teaching research of students’ grade evaluation, the improved iterative random forest algorithm is used for the first time. The automatic evaluation of students’ grades is achieved based on the students’ grades in various disciplines and the number of factors indicating the students’ performance. In a series of experiments the performance of the proposed improved random forest algorithm was compared with the other machine learning models. The experimental results show that the performance of the proposed model was better than the other machine learning models by attaining the accuracy of 88.55%, precision of 88.21%, recall of 95.86%, and f1-score of 0.9187. The implementation of the proposed system is anticipated to be very helpful for the physical education system.

Abstract:

The development of information technology is changing all walks of life. People’s health problem is more and more prominent; people begin to talk about the reform of college sports training. Sports no longer rely on individual games, but on the comprehensive strength of science and technology competition. The fierce competition for Olympic gold medal in modern competitive sports is largely due to the competition of scientific and technological strength of various countries. China has also conducted a lot of research on sports information and made some achievements. Through the investigation, we know that, at present, the provincial level sports teams have established the relevant sports training information management system, which is very effective. The latest scientific and technological achievements are combined with sports to establish the university sports information system. The purpose of this paper is to analyze the university sports physical training information system based on big data mobile terminal, study the big data embedded system, improve the effect of sports skills training, and meet the social demand for high skilled sports talents. This paper uses the literature method, experimental investigation method, and big data spectral clustering algorithm-related experiments to study the advantages of big data and uses the value of big data and embedded system model to study the university sports physical fitness training information system based on big data mobile terminal. The results show that 40.6% of college students spend more time in physical exercise, based on the application of big data embedded system in college sports training; it is of great significance to arrange sports training methods to improve students’ sports training performance.

Abstract:

Poor student achievement in science is a global challenge. Sustainable Development Goals 3 and 4 targeting people’s well-being and quality education as well as previous studies linking physical exercises to improved student memory and increased concentration become relevant. This study, therefore, determined the impact of physical fitness activities on students’ Basic Science achievement. The study adopted pretest, posttest, control group quasi-experimental design. Participants included 125 JS2 students from six schools in Ibadan, Oyo State, Nigeria. Instruments used were stadiometer, gymnasium mats, medicine balls, skipping ropes, cones, stopwatches, weighing scale and Achievement Test in Basic Science (r=.84). The experimental group was exposed to selected science concepts and physical fitness activities simultaneously while the control group was only taught the concepts. Data analysis employed descriptive statistics and Analysis of Covariance. Physical fitness activities had significant effect on students’ achievement (F(1,124)=347.12; P<.05). The experimental group scored higher (x̄=62.58) than control (x̄=53.76). Gender also had significant effect on achievement (F(1,124)=147.89; P<.05) with males performing better (x̄=61.04) than females (x̄=55.29). The interaction effect of treatment and gender on students’ achievement was not significant (F(1,124)=.08; P>.05). Physical fitness activities boosted students’ achievement in Basic Science. Physical fitness activities should, therefore, be implemented in schools.

Abstract:

Background: This umbrella review aimed to summarise the evidence presented in systematic reviews and meta-analyses regarding the effect of physical activity on academic achievement of school-age children and adolescents. Methods: A comprehensive electronic search for relevant systematic reviews and meta-analyses were performed in Pubmed, Cochrane Library, Web of Science, Scopus, and Latin American and Caribbean of Health Sciences Information System, and reference lists of the included studies, from inception to May 2020. Studies were included if they were systematic reviews or meta-analyses, included school-age children or adolescents, the intervention included physical activity, and the outcome was the academic achievement. Two independent authors screened the text of potentially eligible studies and assessed the methodological quality of the studies using the AMSTAR 2 tool. Results: Forty-one systematic reviews and meta-analyses that examined the effects of physical activity on children and adolescents’ academic achievement were identified. Overall, the systematic reviews reported small positive or mixed associations between physical activity and academic achievement. From meta-analyses, it was observed that physical activity had null or small-to-medium positive effects on academic achievement. Chronic physical activity showed a medium positive effect on academic achievement, and acute physical activity did not demonstrate benefits. Conclusions: Physical activity seems not to be detrimental to school-age children and adolescents’ academic achievement, and may, in fact, be beneficial.

Abstract:

In the short historical essay, the ways of formation of Materials Science in Ukraine are considered, and tendencies of its development over the World were taken into account. The outstanding human resources and excellent raw deposit capabilities of Ukraine have led to creating Ukrainian scientific schools back in the days of the Russian Empire, which were comparable to the Ural and another world schools of metallurgists and metal scientists. The further development of science on materials in Ukraine is closely related with establishing the Academy of Sciences in 1918. From the first twelve members of the All-Ukrainian Academy of Sciences, three of them namely V.I. Vernadsky, P.A. Tutkovsky and S.P. Tymoshenko, had represented the natural sciences. The election of E.O. Paton to the Academy in 1929 for "technical sciences" specialty had initiated the usage of promising achievements of fundamental sciences for development of applied ones. Since that, the famous Institutes of Ferrous Metallurgy (1936), Metal Ceramics and Special Alloys (1955) and others were founded. The idea to develop the new area of knowledge, which would combine the different types of interatomic bonding to be resulted in new materials and would not be preferable to metallic materials only, has been already in time, namely in 1963. B.Ye. Paton jointly with I.M. Frantcevych had created the Department of Physical and Technical Problems of Materials Science, which included a few institutes namely: electric welding (Paton Welding Institute, PWI), cermets and special alloys (Institute for Problems of Materials Science (IPMS since 1964), foundry (problems of casting since 1964, and Institute of Physics and Technology Metals and Alloys (PTIMA since 1996), mechanical engineering and automation (Institute of Physics and Mechanics (IPM since 1964). And although the institutions are quite different in their profiles, their uniting direction is materials science. As early as 1963, V.N. Yeremenko was elected as the first academician for the "materials science” specialty. Therefore, the issue of a new collection of scientific papers under the title "Progress in Materials Science" is natural and vitally required. It is corresponding to global trends in the formation of scientific and technical priorities in developed countries and is as the task for Ukraine too.

The article substantiates the conceptual foundations of the postmaterialistic paradigm of science, based on the achievements of quantum physics, synergetics, eniology and the theory of physical vacuum. The principles of the postmaterialistic paradigm (the ontological principle of holism, the principle of teleological hierarchy, the principle of materialistic-ideal complementarity, the anthropic principle of the predefinition of man and the world, the principle of the spiritual determiner of all theories of being) allowing to change radically the methods of energy use, applying the energy potential of the egregore for subtle, non-material matters of reality to upgrade the energy efficiency taking into account the axiological dominant, are explicated.

Abstract:

The aim of this review is to present 3D bioprinting of skin substitutes as an efficient approach of managing skin injuries. From a clinical point of view, classic treatments only provide physical protection from the environment, and existing engineered scaffolds, albeit acting as a physical support for cells, fail to overcome needs, such as neovascularisation. In the present work, the basic principles of bioprinting, together with the most popular approaches and choices of biomaterials for 3D-printed skin construct production, are explained, as well as the main advantages over other production methods. Moreover, the development of this technology is described in a chronological manner through examples of relevant experimental work in the last two decades: from the pioneers Lee et al. to the latest advances and different innovative strategies carried out lately to overcome the well-known challenges in tissue engineering of skin. In general, this technology has a huge potential to offer, although a multidisciplinary effort is required to optimise designs, biomaterials and production processes.

Abstract:

Mental rotation (MR) is the ability to rotate three-dimensional objects using the imagination. As the ability to generate, retrieve, maintain, and manipulate visual-spatial information, MR plays a critical role throughout education and sport. In this aspect our objective in this study was to compare MR performances and academic achievement between students of art, foreign languages (FL), computer-instructional technologies (CIT) and physical education (PE). In the computer-based MR test, the image files of the library “Mental Rotation Stimulus Library” were used with the written permission of the author. A total of 144 participants composed of 79 males and 65 females volunteered in the study. Comparing the academic achievements (AA) with the PE group and art, CIT, FL and control groups; it was observed that all the groups are better than PE (p < 0.05). However, no significant difference was found between PE and all groups in MR performances (p > 0.05). In conclusion, PE students performed similarly with other students in terms of MR, although their AA were low. MR ability is clearly related not only to problem solving, acquiring mathematical knowledge and academic thinking but also to motor abilties.

Abstract:

This research was embarked on to explore the underperformance of Physical Sciences learners and the subsequent increasing unpopularity of the subject in South African rural schools. As poor academic achievement in science is a concern in many countries and not only in South Africa, qualitative research was undertaken to determine whether assessment can contribute to the improvement of learners’ academic achievement in this particular school subject. The research uses the Cultural and Historical Activity Theory as theoretical lens to analyse how assessment can improve the academic achievement of learners. Data were collected by means of face-to-face interviews with teachers, school principals and subject advisers, the “community” as advocated by the Activity Theory, while focus-group interviews were held with the learners who are the “subjects” in the Activity Theory. Verbatim findings highlight the views of participants and reveal that though efforts are made to incorporate a variety of informal assessment methods, key issues such as poor formulation of questions, weak comprehension skills and unsatisfactory interpretation of questions, remain a problem. Based on these findings, recommendations for improvement are proposed. Key words: case study; improving science achievement; physical sciences assessment; rural schools

Learning achievement is the result achieved by someone after doing the learning process. One of the factors that influence learning achievement is the use of the learning model. This study aims to know the differences in achievement of students learning to use problem-based blended learningmodels and traditional blendedlearning. This study uses a quasi-experimental method of "non-equivalent pretest-posttest control group design." The study population is all class X IPA with a total of 6 classes or 210 people. The sample consists of 3 classes or 107 people.Student learning achievement data were analyzed by descriptive analysis and ANOVA one-way (α= 0.05). The results of this study reveal that there are differences in student achievement due to the learning model. Higher learning achievement was achieved by problem-based blended learningmodels (F = 264.307; α<0.05). The LSD test results showed that the learning achievement of students in the MBLBM group was higher than MBL, the learning achievement of the MBLBM group was higher than that of MPK, and the learning achievement of the MBLBM group was higher than that of MPK.

Abstract:

Inclusive Education (IE) of children with atypical development is a great challenge, as schools here, predominantly do not grant them admission, on grounds of having negligible infrastructure to cater to their needs. This is usually based upon inaccurate presumptions about the children’s (impoverished) physical, social, communicative, intellectual and literacy skills, and creates more obstacles towards achieving IE. The UN establishes education as every child’s right and proposes that, all children regardless of their abilities must go to the same school, making it incumbent on the school system to fulfill the requirements of every child. Today, the developed countries have a well established IE system, and have nearly shelved the ‘special school’ methodology. To ascertain, this realm in Karachi the speech language therapists and students of College of Speech Language & Hearing Sciences(CSLHS), Ziauddin University, indulged with five parents, whose children, despite having speech-language impediments, found a way into mainstream schools, in here. The aim was to gain an insight towards achieving IE for all children deserving to be integrated into mainstream schools in Pakistan. The results of this study although not very encouraging, pointed towards establishing early intervention, and training school personnel in identifying and working with differently-abled children in their classroom.

Abstract:

Purpose The purpose of this paper is to explore teaching methods that can allow learners to be creative and proactive. The learners should be able to solve problems, make decisions, think critically, communicate ideas effectively and work efficiently. Teaching and learning are evolving and developing in many countries, with a focus concerning what is actually learned through effective teaching methods. Design/methodology/approach A qualitative research was carried out, identifying effective teaching methods and exploring their roles in teaching and learning in physical sciences in selected rural secondary schools. Face-to-face interviews with physical sciences teachers, school principals and curriculum advisers were used to collect data. Findings A range of teaching methods that may be integrated into teaching and learning activities is identified. The teaching methods ensure that topics are discussed and explored through interaction and sharing of perspective, views and values through which new learning can emerge. Viewed from this perspective, there is a need to create a stimulating, enriching, challenging and focused environment for physical sciences learners through the use of multiple teaching methodologies. Research limitations/implications The improvement of science learner’s academic achievement requires also the teachers to develop new skills and ways of teaching the subject. Improving learner academic achievement in physical sciences requires an approach to improve the skills of teachers as well, which focuses on the effective use of teaching methods such as experiments. This means attempting to change the attitude of teachers to regard the processes of teaching and learning as central to their role. In addition, the achievement of learners in science could possibly solve the problem of shortages of engineers, skilled artisans, technicians, doctors and technologists for sustainable development. It is important to create conducive conditions for learning and teaching in physical sciences, and continue to progressively and within available resources, realise that collaboration, problem-solving and hands-on activities are effective teaching methods to improve learner academic achievement. Practical implications The learners should be able to solve problems, make decisions, think critically, communicate ideas effectively and work efficiently. The study is limited to the teaching methods used in physical sciences. Hands-on activities are essential in science teaching and learning. Social implications The use of collaborations, peer teachings and hands-on activities allows learners emphasise the creation of a classroom where students are engaged in essentially open-ended, student-centred and hands-on experiments. Originality/value The paper is original work, in which face-to-face interviews were carried out. Qualitative research was carried out. The paper could assist educators in the teaching of physical sciences in secondary schools using the identified methods. The results were obtained from physical sciences educators, school principals and curriculum advisors in South Africa. Poor academic achievement in rural areas is a concern, and therefore, the paper provides effective methods which can be used by educators in the teaching of physical sciences in rural areas.

Abstract:

Nowadays, there is a general penetration of ecology in other related sciences. Soil science is not an exception. To the evidence of this, the works of soil scientists may serve, that have appeared recently. It is shown that the ecology of soil is a broader area of the genetic soil science, than ecological soil science. In addition to the doctrine of the ecological functions of soil, modern soil ecology also includes the factor ecology and the doctrine of biosphere soil conservation. In modern soil science there are 2 main areas – fundamental, which aims to study all the features of soil as a natural body, and applied that examines various aspects of soil use by man. At the same time it should be noted that most of soil scientists until recently isolated a genetic soil science in two main areas – the genesis and the geography of soils. Academician L. I. Prasolov (1978) was the first who proposed to allocate soil ecology in a separate section of soil science, along with the above directions. V. R. Volobuev (1963) hold on to the similar views. I. A. Sokolov (1993) showed that the section «Soil ecology» is equal to such sections of soil science as the «Genesis of the soil» and «Geography of the soil». N. A. Gorin (2005) hold on to the similar point of view. On this basis, we offer the following vision of the place of soil ecology in the structure of modern soil science. This scheme is based on the allocation of basic research in the areas of soil science by the team of authors under the leadership of the Moscow State University V. A. Kovda and B. G. Rozanov (Pochvovedenie, 1988). The classification of the historic area of soil science is identified with the genesis of soil by us, and pedography – with the geography of soil. The scientific achievements of other fundamental areas (pedognostika, dynamic soil science, regional soil science, history and methodology of science) are widely used to address key issues of historical soil science and pedography. The structure of the direction «Ecology of soil» is developed by academician G. V. Dobrovolsky and E. D. Nikitin (2012). This doctrine of the ecological functions of soil, classification by B. F. Aparin (2012) is a fundamental direction, the theoretical basis of ecological soil science, related to the applied directions. After L. O. Karpachevsky (2005), who considers the ecological functions of soil subject as ecological soil science, we identify the ecological soil science with the doctrine of the ecological functions of soil in some extent. This view is confirmed by the definition of ecological soil science, formulated G. V. Dobrovolsky and G. S. Kust (2012) – «This is a direction in modern soil science, studied the role of soil as a unique habitat of plants, animals, microorganisms, and especially – in human life, in the functioning of the biosphere and the individual ecosystems». From the above definition, it is clear that in this case, the authors believe that the core of ecological soil science is ecological functions of soil, which manifest themselves through their specific role in nature and human life. The subject of the study of ecological soil science, as indicated by L. O. Karpachevsky (2005), is the ecological functions of soil. Modern physics of soil – is the area of soil science that studies the physical properties of the soil and the place in which physical processes are flowing (Voronin, 1986). As you can see from the definition, the ecological functions of soil caused by the physical properties of soil, remain outside the field of soil physics research. For this reason, there is a need for the provision and the development of ecological soil physics, which is based on theoretical and practical achievements of classical physics of soil, and will also pay close attention to research the ecological functions of soil.

Abstract:

This research analyzes the voices of university students of sport sciences during the implementation of strategies to support autonomy and collaboration in gymnastic learning, from the perspectives of self-determination, self-control, and self-regulation. The methodology is qualitative and the self-reflective journals with their narrative are the tool to collect information. The strategy is well appreciated both in terms of the structure of the work plan and in the guidance of the tasks. The evolution of motivation, autonomy, collaboration, and achievements is highly valued throughout the process. However, the final assessment, despite having little effect on the grade, produces pressure and anxiety in students, so that self-control decreases, action is impaired, and the motivation achieved in the learning process is distorted. Further studies are needed to design coping strategies to help students maintain their motivation and confidence and to decrease students’ resistance to assessment tasks.

Abstract:

Achieving the recommended levels of physical activity (PA) is associated with better health. Despite this, most undergraduate students report low levels of PA. This study aimed to assess the achievement of recommended PA levels in a wide sample of undergraduate students from Madrid (N = 2960). Overall PA and leisure-time PA (LTPA) were measured with the Global Physical Activity Questionnaire (GPAQ). Descriptive analyses and logistic regression were performed. It was revealed that 22.4% and 55.6% of overall PA and LTPA, respectively, did not achieve World Health Organization (WHO) recommendations. When PA was measured as overall PA, the achievement of the recommended level was positively predicted by male sex; a Body Mass Index (BMI) indicative of normal weight or being overweight; spending less time sitting or reclining; work; and studying health science, social sciences, engineering, or architecture (all p < 0.001; r2 = 0.075). Using LTPA, the positive predictors of achieving recommended PA levels were male sex, having a BMI indicative of normal weight or being overweight, work, studying at a public university, and studying health science (r2 = 0.048). These findings suggest that universities should implement strategies to promote PA.

Science and technology capabilities are fundamental for social and economic progress in African countries and they are crucial components aimed at fostering growth and development of every nation as they create impact on the various sectors of governments. Maintaining and Strengthening the contributions of science and technology become more important for Africa in addressing traditional development issues and successful application of science and technology entails establishing effective institutional framework and linkages so that the various science and technology institutions and the productive sectors work in a system that is focused on achieving developmental goals without undue duplication and completion. Unfortunately, many developing countries especially the poor countries in West Africa do not have human resources, physical and economic infrastructures and access to capital to take full advantage of the science and technology expertise and achievements of the developed countries like the USA, China, and Korea etc. Conclusively, it is imperative for Africa especially West African countries to embrace science and technology as a vital tool for accelerating their socio-economic development as science and technology enhances its international competitiveness and more importantly its position in the world economy.

Abstract:

In silicon-on-insulator (SOI) technology, devices are dielectrically insulated from one another—usually by silicon dioxide. Unlike in conventional silicon devices, there is no direct contact between a transistor and the silicon substrate. The advantages of this type of isolation are many: reduced parasitic capacitances and reduced crosstalk between devices, improved current drive, subthreshold characteristics, and current gain. Silicon-on-insulator devices have been and are being used in several niche-market applications such as hightemperature and radiation-hard integrated circuits. However most importantly, SOI technology seems perfectly adapted to the needs of low-voltage, low-power (LVLP) electronic circuits. Because of the growing market for portable systems, LVLP technology is bound to soon become one of the drivers of the microelectronics industry, and SOI is likely to be part of it. Moreover major companies such as IBM, Sharp, Motorola, and Peregrine have announced upcoming lowpower and high-frequency lines of SOI products. The goal of this article is to introduce the reader to the basics of SOI device physics and the integrated-circuit applications of SOI.

This paper studies the determinants of educational outcomes in the Republic of Tatarstan, Russia. Using principle component analysis, least squares with robust standard errors, and probit models, I found that family resources, including socioeconomic status, cultural and social capital, show a statistically significant effect on educational achievements and plans about educational trajectories. However, little of the variation in the dependent variables can be explained by variation in family resources. In Tatarstan, as in developed countries, family resources have a low influence on educational outcomes. Moreover, school quality, gender, nationality, peers, health, plans about future work, and other physical and psychological factors play important roles in influencing educational outcomes. Girls obtain better results than boys, and Tatar speakers show higher educational achievements than Russian speakers.

Abstract:

<p class="1">Besides the limitation of cognition level, the factors that affect the correctness of academic evaluation are as follows: collusion-recognization effect, backfire effect, cognitive maladjustment, inattentional blindness and aesthetic fatigue. It's hard for readers (especially the reviewers of academic achievements) not to fall into the trap. Therefore, the probability of misjudgment of academic achievements of "questioning and denying current prevailing theories or creating new theories" is very high. The intolerable contradictions in the existing physical theories, such as space paradox, time paradox, quantum entanglement paradox, are exposed by means of thought experiments and "to present the facts, reason things out", and take these works as examples to reveal the formation and utilization of these adverse psychological effects. The conclusions are as follows: both special relativity and Copenhagen interpretation of quantum mechanics have fatal injury; it is difficult to eliminate the misjudgment of academic achievements, but the misjudgment rate can be reduced. The concepts of “invariance of spatial attribution” and “inaction association” are established.
