Race walking is a discipline in which the best chronometric performance is constrained by infringements. Currently, the judgment and training of race walkers is entrusted to subjective observations made by judges. In this paper, with the objective of supporting coaching and judging, we present a wearable inertial sensor system (IART) for the evaluation of performances and infringements in race walking. The system is composed of an inertial sensor positioned close to the center of mass of the subject and a management unit designed for coaches and judges. IART allows: (i) a step sequence classification according to the competition rules; (ii) a customized assessment of elite race walkers based on key performance and infringement indices. The system is experimentally validated in field conditions by nine world-class Olympic race walkers. The results show that IART improves the current evaluation of step sequences and offers a meaningful support for the overall evaluation of the technical gesture.

Today, worldview, spiritual and moral problems that have always been reflected in education and upbringing come to the fore in society. In this situation, there is a demand for philosophical categories. One of the priority goals of education in modern conditions is the formation of a reasonable, reflexive person who is able to analyze their actions and the actions of other people. Modern science is characterized by an understanding of the absolute value and significance of childhood in the development of the individual, which implies the need for its multilateral study. In the conditions of democratization of all spheres of life, the child ceases to be a passive object of education and training, and becomes an active carrier of their own meanings of being and the subject of world creation. One of the realities of childhood is philosophizing, so it is extremely timely to address the identification of its place and role in the world of childhood. Children's philosophizing is extremely poorly studied, although the need for its analysis is becoming more obvious. Children's philosophizing is one of the forms of philosophical reflection, which has its own qualitative specificity, on the one hand, and commonality with all other forms of philosophizing, on the other. The social relevance of the proposed research lies in the fact that children's philosophizing can be considered as an intellectual indicator of a child's socialization, since the process of reflection involves the adoption and development of culture. Modern society, in contrast to the traditional one, is ready to "accept" a philosophizing child, which means that it is necessary to determine the main characteristics and conditions of children's philosophizing.

In the digital era, the success of the professional development of future specialists in the process of obtaining higher education largely depends on their professional orientation (PN). Despite the significant interest in the subject of the study, the problem of identifying the factors that affect PN remains poorly understood. The purpose of the study is to determine the factors of the formation of PN of students enrolled in training and retraining programs, and the features of PN in the digital era. The article reveals the content and structure of the PN of future specialists in the era of digitalization. According to the results of the empirical research, the relationship of students' PN with indicators of life-meaning orientations, motives for choosing a profession and training was revealed; the relationship between students' life-meaning orientations and indicators of motives for choosing a profession and training at the stage of digitalization of education. The factors influencing the personal condition, and the factors of the formation of the personal condition of students, who are trained according to the programs of training and retraining of specialists, have been determined. As a result of an empirical study, it was concluded that a negative impact on the formation of PN is created by factors caused by various life circumstances, lack of independence of decisions in choosing a profession, low reflection of life goals, prospects for the future, rigidity of volitional and personal qualities, internal conflict in the structure of personality relationships, low pleasure training and the like. At the same time, the level of PN is significantly higher among students who receive a second higher education and who understand its importance at the stage of digitalization of education.

Singapore's government formulated the Global Schoolhouse, a policy platform based on three pillars: investing financial support with an identified group of “world-class universities” to establish operations in Singapore; attracting 150,000 international students by 2015 to study in both private and state-run education institutions; and remodel all levels of Singaporean education. Its knowledge economy plans require Singapore's citizens to be self-reliant, to better themselves through education and training, and if necessary to relocate themselves regionally to exploit opportunities, rather than expecting their government to take responsibility for their employment.

The standardised testing of school children has been the subject of significant news media attention in recent years in many developed countries around the world. This article examines the reporting of annual National Assessment Program Literacy and Numeracy (NAPLAN) tests in three major Australian newspapers, with a particular focus on the portrayal of school teachers in the coverage. Overall, teachers were presented as strongly opposed to NAPLAN and the publication of test results, yet the newspapers themselves supported the tests as an important accountability measure. Teachers were depicted as trying to influence the testing system through teaching to the test and cheating. They were presented as generally inadequate as teachers, and were blamed for perceived failings in the educational system. These findings point to implications for teacher recruitment and retention, and for journalism education and training.

This chapter discusses how there was a good deal of confusion about what strategy to follow in defending East Africa. The thinking of the few politicians interested in the subject, and within the regional governments, was flawed, with the dangers misunderstood or overlooked. Successive British governments showed no real sense of recognizing that this could be an important wartime hub for raw materials and training. These significant failings were compounded by the failure of senior military officers to make a compelling argument about Italian intentions and the potential challenge these presented. While the Chiefs of Staff in London were right to assume that Mussolini would focus on Egypt, due to the vital importance attached to controlling the Suez Canal, they were wrong to conclude that he would enter the war at the first opportunity.

The subject-matter of this paper is one that I have always taken a great interest in since my connection with psychology, believing it to be the key-stone to modern treatment of the insane, and a valuable adjunct in setting a good example to a class of people who are prone to do evil as the result of their mental aberration, or the tendency to do nothing, or from want of something to do. It is a truism that work is a powerful antidote to low spirits, and if we contrast the asylum treatment of to-day with that of years ago, how strange and startling is the effect!

Background Falls are a common health problem, which in the worst cases can lead to death. To develop reliable fall detection algorithms as well as suitable prevention interventions, it is important to understand circumstances and characteristics of real-world fall events. Although falls are common, they are seldom observed, and reports are often biased. Wearable inertial sensors provide an objective approach to capture real-world fall signals. However, it is difficult to directly derive visualization and interpretation of body movements from the fall signals, and corresponding video data is rarely available. Objective The re-enactment method uses available information from inertial sensors to simulate fall events, replicate the data, validate the simulation, and thereby enable a more precise description of the fall event. The aim of this paper is to describe this method and demonstrate the validity of the re-enactment approach. Methods Real-world fall data, measured by inertial sensors attached to the lower back, were selected from the Fall Repository for the Design of Smart and Self-Adaptive Environments Prolonging Independent Living (FARSEEING) database. We focused on well-described fall events such as stumbling to be re-enacted under safe conditions in a laboratory setting. For the purposes of exemplification, we selected the acceleration signal of one fall event to establish a detailed simulation protocol based on identified postures and trunk movement sequences. The subsequent re-enactment experiments were recorded with comparable inertial sensor configurations as well as synchronized video cameras to analyze the movement behavior in detail. The re-enacted sensor signals were then compared with the real-world signals to adapt the protocol and repeat the re-enactment method if necessary. The similarity between the simulated and the real-world fall signals was analyzed with a dynamic time warping algorithm, which enables the comparison of two temporal sequences varying in speed and timing. Results A fall example from the FARSEEING database was used to show the feasibility of producing a similar sensor signal with the re-enactment method. Although fall events were heterogeneous concerning chronological sequence and curve progression, it was possible to reproduce a good approximation of the motion of a person’s center of mass during fall events based on the available sensor information. Conclusions Re-enactment is a promising method to understand and visualize the biomechanics of inertial sensor-recorded real-world falls when performed in a suitable setup, especially if video data is not available.

Investigative Activity

This article carried out a detailed scientific analysis of the nature and content of operational search tactics. Analysis of the vocabulary literature suggests that, despite minor differences in the interpretation of the concept of tactics, in general, this term means "an integral part of the art of war that combines the theory and practice of preparing and conducting combat." According to the results of the study, it was established that the theoretical basis for the formation of operational-search tactics was the groundwork of forensic scientists. The author's wording of the concept of “operational-search tactics” is provided as a direction of operational-search activity, formed on the basis of its theoretical principles and practical experience of entities carrying out this activity legally with the goal of fulfilling the tasks stipulated by the Law of Ukraine “On operational-search activity” Based on the analysis of the scientific heritage of scientists, it has been established that operational-search tactics in the theory of operational-search activity can be divided into general and special ones.The questions about the delimitation (ratio) of the tactics of secret investigative (search) actions and tactics of operational search activities are considered. Despite some common signs of tactics for conducting secret investigative (search) actions and operational search activities, it should be remembered that investigation tactics are traditionally considered in the framework of criminalistics, but operational search activities are the subject of the study of the theory of operational search activities. At the same time, it was noted that the tactics of secret investigative (investigative) actions, although individual in their sense, should predominantly be based on the provisions of operational investigative activity, and not criminalistics, at least taking into account the fact that the theoretical and practical operational search tactics worked over the years.It is concluded that both forensic and operational search tactics will require a high-quality update. In particular, the results of a survey of investigators and operational workers indicate the need and desirability of borrowing foreign experience in terms of education and training of investigators and operational units on tactics of identifying, preventing and investigating crimes in the field of high technologies (as noted by 81% of respondents).

In this research, the use of ICTs in India by librarians, particularly in the use of mobile phones, was the focus of this study. To gather the required data for the research, surveys were performed and this approach was implemented. The questionnaire was presented to eight librarians from eight teacher college libraries in the subject of study who responded to it, and the results were used to inform the research. According to the conclusions of the study’s materials, ICT use by professional librarians in India is still a relatively recent phenomena, and as a result, it is still in its early phases. The study showed that while libraries utilise information and communications technology (ICT) to deliver some services, these services are insufficient in part as a result of challenges such as a lack of money, a scarcity of trained personnel, and a lack of managerial support. According to the findings of this study, college librarians should get training in information and communications technology literacy since ICT is a dynamic, continuously practising, and training environment that they should take advantage of, as demonstrated by the results of the study. It was proposed that students have access to contemporary ICT instruments, such PCs, printers and scanners, to help them with their home maintenance tasks in order to enhance the administration of educational institutions. The recommendation was also made that libraries should get sufficient help in this respect. The research also advised that college bibliographers participate in attachment programmes with the help of students at the major university libraries to understand the finest practises of modern librarians.

AbstractThe classical approach for tackling the problem of drawing the 'best fitting line' through a plot of experimental points (here called a scenario) is the least square process applied to the errors along the vertical axis. However, more elaborate processes exist or may be found. In this report, we present a comprehensive study on the subject. Five possible processes are identified: two of them (respectively called VE, HE) measure errors along one axis, and the remaining three (respectively called YE, PE, and AE) take into consideration errors along both axes. Since the axes and their corresponding errors may have different physical dimensions, a procedure is proposed to compensate for this difference so that all processes could express their answers in the same consistent dimensions. As usual, to avoid mutual cancellation, errors are squared or taken in their absolute value. The two cases are separately studied.In the case of squared errors, the five processes are tested in many scenarios of experimental points, both analytically (using the software Mathematica) and numerically (with programs written on Python platform employing the Nelder-Mead optimization method). The investigation showed the possible existence of multiple solutions. Different answers originating from different starting points in Nelder?Mead correspond to solutions revealed by analytic search with Mathematica. For each scenario of experimental points, it was found that the best lines of the five processes intercept at a common point. Furthermore, the point of intercept happens to coincide with the 'center of mass' of the scenario. This fact is described by stating the existence of an empirical 'Meeting Point Law'. The case of absolute errors is only treated numerically, with Nelder?Mead minimizer. As expected, the absolute error option shows greater robustness against outliers than the square error option, for all processes. The Meeting Point Law is not valid in this case.By taking the value of minimized error as a criterion, the five processes are compared for efficiency. On average, processes PE and AE, that consider errors along both axes, resulted in the smallest minimized error and may be considered the best processes. Processes that rely on errors along a single axis (VE, HE) stay at the second place. In all cases, YE is the process that results in the largest minimized errors
