Kicking in soccer has been the subject of scientific research for more than 40 years yet review articles summarizing the biomechanical fundamentals of kick optimization as a guide to coaching are scarcely to be found. The current review article aims to bridge the gap between scientific research into the maximal instep kick (including studies employing 3D motion capture and full-body biomechanical modelling) and the application of such research in coaching. It does so by supplying a scientifically founded, coaching-friendly article explaining identifiable characteristics and motor control sequencing that define this skill. Relevant biomechanical factors are identified in a way that should help coaches better develop training programmes and, at the same time, foster better understanding of the skill among athletes. Such information will contribute to both accelerated skill acquisition and, by concomitant gains in skill efficiency, the development of programmes that minimize risk of injury to athletes during training. 相似文献

This article is concerned with early modern interpretations of Hanno the Navigator's Periplus, an ancient travel account of a Carthaginian voyage down the coasts of Africa. The early modern period saw a rise in interest in geographical knowledge, and the ways in which different authors used Hanno's voyage reflects their understanding of the role of geography in conceptualising the world. In these discussions, writers had to negotiate between the confusing portrayals of the voyage in the received classical tradition and new reports brought by voyages of exploration. Here, I will discuss how these syntheses between humanist methods and contemporary travellers' accounts were shaped by the economic and political concerns tied to the first wave of European overseas expansion. Amid this climate, ancient geographical knowledge found pragmatic applications in contemporary issues of navigation, commerce and claims of territorial possession, as well as shaping European perceptions of ‘self’ and ‘the other’. This paper thus seeks to situate humanist practices and classical knowledge within the wider context of overseas voyages and early modern political and economic developments. 相似文献

Historians’ continuing interest in the origins of the Spanish Civil War has recently extended to the colonial policies of the Spanish Second Republic in Morocco, a relatively unexplored issue in previous decades, which has informed new approaches to the military uprising of July 1936. Foreign sources and archives, however, have been generally overlooked in this context. This article claims that British and French delegates in Morocco made critical observations about republican reforms in Spanish Morocco, which have much to add to this debate. They raised questions regarding the continuity of republican policies in Morocco and the anti-republican attitudes within the Army of Africa. They also challenged conventional knowledge concerning the difficulties encountered by alternative colonial projects in Morocco. In the end, their reports not only questioned metropolitan options but also anticipated the attitudes of the British and French governments, vis-à-vis the military rebellion. 相似文献

The article addresses narratives that tell of a member of the 10 Lost Tribes of Israel who comes to the rescue of a Jewish community. The tales were documented at the Israel Folktale Archives, in the second half of the twentieth century, and were told by informants from Morocco and Greece. While it is probably impossible to trace the exact routes of these “cultural possessions”, around and across the Mediterranean, the texts nevertheless provide a glimpse into the ways in which a network of Jewish communities shared a meta-narrative while adapting it to their own regional contexts. Although these tales are quintessentially diasporic, they also provided a platform for negotiating post-exilic identities in the new Israeli national context. 相似文献

The benefits of urban open spaces for improving the quality of life and sustainability in cities are widely recognized. The functions they perform within the framework established by urban planning, as well as their metrics, are now more complex than in the past. It is convenient to develop methodologies for the evaluation of these spaces adapted to the present time to check their level of efficiency, which is useful in urban planning for the establishment of new urban open spaces. The aim of this study is to classify such spaces through a methodology that integrates spatial analysis, configuration analysis, and decision support so as to understand their complexity from a more advanced analytical perspective. In order to do this, a prior exploration of specific literature is carried out, which allows the characterization of the functions of urban open spaces by means of the corresponding analysis variables in a weighted manner. The integrated combination of these advanced tools is a step forward in achieving consistent and detailed results for urban open spaces. They perform their functions best in dense, central, equipped, accessible, connected, and easily walkable urban environments. In addition, future recommendations are provided. 相似文献

中国城市群空间结构演化的影响因素分析——基于铁路客运的功能联系视角 总被引:1,自引:0,他引:1
以中国13个城市群为研究对象,采用铁路客运班次构造多中心指数来表征基于功能联系的城市群空间结构,在分析城市群空间结构演变基础上重点分析其影响因素。研究发现,基于功能联系视角的城市群空间结构总体呈单中心化趋势,但地区差异化明显,珠三角、山东半岛和闽东南城市群已表现出多中心化特征;城市群空间结构的多中心程度随经济发展水平的提高表现为先单中心后多中心的演变过程;城市群规模的增大和城市间联系加强促进了城市群向多中心方向演化;而面积小、三产比重高的城市群更有利于形成单中心的结构;政府干预作用对城市群空间结构影响并不显著。鉴于不同城市群空间结构演化趋势不同,未来政策取向应该遵从各个城市群自身规律。 相似文献

The Royal Artillery Factory of Seville in Spain originated from pre‐existing private bronze foundries dating from the 16th century. The paper analyses the stratigraphy of wall cladding in the areas traditionally known as the ‘Old Foundry’ and the ‘New Foundry’, through its characterization by optical microscopy, scanning electron microscopy with energy‐dispersive X‐ray spectrometry (SEM‐EDX), micro‐X‐ray fluorescence (μ‐XRF) and micro‐X‐ray diffraction (μ‐XRD), in order to analyse the metal deposits that have accumulated since the 17th century. The data obtained allowed the verification of the available historiographical information and the location of the original bronze smelting furnaces. The analysis of patinas deposited on the overlapping layers of lime also confirmed that neither the raw materials nor the composition of the alloys used presented any substantial changes. 相似文献

Within the making of Portuguese liberal‐representative democracy, the Portuguese Communist Party became a major actor in local government in urban deprived peripheries, shaping Lisbon's Red Belt. In this article, we analyse the communist discourse on the Portuguese urban question, showing how it politicised the urban as a site of unevenness and deprivation, but simultaneously depoliticised it by refusing to acknowledge it as a proper space for conflict. This historical account leads us to a critical debate with proposals that discuss urban politicisation by ontologising “the urban” or “the political”—we argue that these approaches tend to be less helpful in understanding processes of contingent, partial and inter‐related forms of politicisation/depoliticisation of the urban in itself. In contrast, we argue for a more attentive theorisation on politicisation–depoliticisation of the urban condition as a most valuable path to grasp situated formulations of citizenship and, hence, configurations of political regimes. 相似文献

The Australian Army, while having a long association with Papua New Guinea after the Second World War and before independence in 1975, is often conceptualized as a small player in the decolonization process, of interest to scholars because of its cost and potential threat to democratic government. This article examines the Army’s education programme and associated policies in the decade before independence to argue that the institution was acutely aware of looming decolonization, and actively sought to create a national Papua New Guinean military by repurposing policies originally designed to serve Australia’s defence needs, in particular through ‘civic’ education. It embarked on this path without direction from the Department of Territories. While the results of ‘civic’ education are difficult to determine, this article shows that the Australian Army was engaged in the profound shifts occurring around it in Papua New Guinea. 相似文献
