This paper describes human application of their knowledge and technological ability to fly and continue to enhance that power. Through application of their knowledge and technological ability, human beings have evolved the ability to fly and continue to enhance that power. Aircraft technology evolution is about the evolving design of the human movement on the Earth’s surface: people, goods, materials, and everything else. As the whole vehicle or animal evolves toward becoming better at moving mass on the landscape, the organs remain imperfect, because each represents a compromise. The whole vehicle or animal is a construct of organs that are ‘imperfect’ only when examined in isolation. The vehicle design evolves over time and becomes a better construct for moving the vehicle mass on the world map. Flow architectures are evolving right now, throughout nature and in technologies. The legacy of all flow systems (animate and inanimate) is: they have moved weight horizontally and improved the efficiency of that movement because of design evolution.

In sport such as darts, athletes are particularly challenged by demands for concentration, skills underpinned by implicit learning, and fine motor skill control. Several techniques have been proposed to improve the implicit learning of such skills, including quiet eye training (QET) and quiet mind training (QMT). Here, the authors tested whether and to what extent QET or QMT, compared with a control condition, might improve skills among novice dart players. In total, 30 novice dart players were randomly assigned either to the QET, QMT, or a control condition. Dart playing skills were assessed four times: at the baseline, 7 days later, under stress conditions, and at the study’s end. Over time, errors reduced, but more so in the QET and QMT conditions than in the control condition. The pattern of the results indicates that, among novice dart players and compared with a control condition, both QET and QMT provide significant improvements in implicit learning.

Imperial expansion cast European sport, embedded with moral codes and social divisions, across Africa. The government, the church, schools, and the army encouraged colonized peoples to play sport because of its professed ability to discipline and to civilize. Yet sport in Africa developed in the context of existing local ideas about appropriate human movement. Over time, African sport reflected both indigenous and European organization, ideas, and aesthetics, with football (soccer) becoming a particular object of passion. The era of decolonization came with sporting independence. Sport provided a platform for newly independent African nations to consolidate national and pan-African identities and assert full membership and power in the international community, though it could prove divisive as much as integrative, depending on the situation. From continental cups to Western-style sport gatherings, continuities with imperial pasts informed postcolonial African sport. Yet sport also provided a bulwark of resistance against colonial hegemony and racist regimes on the continent. Well into the 20th century, boycotts of sport gatherings and events were threatened and carried out in protest against racist regimes in southern Africa.

Since the 1981 publication of Perspectives on the Academic Discipline of Physical Education, the history of physical activity has secured a prominent place in the field of kinesiology. Yet, despite encouraging signs of growth, the subdiscipline still remains an undervalued player in the “team scholarship” approach. Without the integration of historical sensibilities in kinesiology’s biggest questions, our understanding of human movement remains incomplete. Historians of physical activity share many “big questions” and “hot topics” with researchers in other domains of kinesiology. Intriguing possibilities for integrating research endeavors between historians and scholars from other domains beckon, particularly as scientists share the historical fascination with exploring the processes of change over time.

Human Movement detection is vital in Tele-presence Robots, Animations, Games and Robotic movements. By using Traditional methods with the help of sensor suits it is difficult to find and interpret the movements. As it includes so much sensor data which is difficult to interpret, find the action and send to long distances. It is also very expensive and bulky too. Image processing and computer vision provides a solution to detect and interpret Human movement based on R-CNN approach. It is cheap, easy and light weight algorithm. It takes the video input and divides it in to frames, then it is Human body is separated for the background image. This paper mainly focused on skeleton, its major points and its relative positions in successive picture frames. A set of frames (Video) is given as input to the model, so that the model compares the coordinates of the successive frames and estimates the movement. First, the human is identified and separated from the rest of the image by drawing a bounding box around the human by using CNN (Convolution neural networks), then by applying R-CNN human is segmented and converted to skeleton. From the shape of the skeleton we can identify whether the skeleton is that of a human or not. Comparing the relative coordinates of skeletons extracted from frames photographed over time gives the movement of the human and its direction.

A need-supportive environment can provide various motivational benefits to impact children’s psychomotor developmental levels. However, very little is known about the effects of need-supportive motor skill intervention on children’s motor skill competence and physical activity by gender. Guided by self-determination theory (SDT), this study aimed to (a) investigate the effect of a need-supportive fundamental movement skill (FMS) program on children’s FMS competence and moderate-to-vigorous physical activity (MVPA), and (b) explore potential gender differences in these effects. Thirty-six children (63.8% girls; Mage = 6.52 ± 0.97) participated and were divided into two groups: an intervention group (24 need-supportive FMS sessions over eight weeks) and a control group. A repeated-measures multivariate analysis of variance (MANOVA) was used to examine the influence of the motor skill intervention on FMS competence and MVPA over time by group (intervention, control) and gender (boys, girls). The results showed (a) significant group differences between the intervention and control group in FMS competence and MVPA (p < 0.001), (b) non-significant gender differences between boys and girls in FMS competence and MVPA (p = 0.85), and (c) non-significant interaction effects over time (p = 0.52). The findings highlight that a need-supportive FMS program may enhance FMS development and daily physical activity for both genders during the early school years.

When comparing social science phenomena through a time perspective, absolute and relative difference (RD) are the two typical presentation formats used to communicate interpretations to the audience, while time distance (TD) is the least frequently used of such formats. This article argues that the chosen presentation format is extremely important because the various formats suggest different substantive interpretations. To elaborate upon this issue, researchers from the National Statistical Office, National Health Institute, and general academia were invited to participate in an experiment with alternative presentation formats that describe changes in certain social science phenomena over time. The results revealed a prevailing tendency of respondents to rely on interpretations related to absolute differences, which was additionally reinforced with graphical presentation formats. Therefore, whenever RD or TD is more proper for substantive interpretations, the corresponding presentation format must be designed with special attention.

Spatial interaction modeling can be embedded in the framework of statistical thermodynamics. This has been shown in part by Wilson and by Erlander, in particular. However, to complete the embedding, it is necessary to ask the dynamic question of how a migratory population evolves over time from one (observed) distribution at time t0 to another (observed) distribution at time t1, rather than just the question of how many people who started in one area at t0 ended in another at t1—with no regard to the intermediate locations of the migrants. The manner in which such evolutionary processes are addressed in the context of equilibrium and nonequilibrium thermodynamics serves as a basis for extending the spatial interaction model of human movement.
