Biomechanics of coaching maximal instep soccer kick for practitioners

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.

Merchants' attitudes to work in the Barcelona of the later Middle Ages: organisation of working space,distribution of time and scope of investments

The debate concerning the attitude to work of medieval and renaissance merchants has been one of the most intense in twentieth-century historiography. Arising from the publication of the classic works of the sociologist Max Weber, the debate entered the field of historiography proper after the appearance of articles by Werner Sombart and Henri Pirenne. In the 1950s and 1960s, the works of Yves Renouard and Armando Sapori centred discussion on the development of a specifically mercantile culture in the Italy of the Middle Ages and the Renaissance. In this historiographic context, the article below is an attempt to approach, through original sources, the figure of the merchant in late medieval Barcelona. These sources are inventories, wills, and marriage contracts, through which is offered a three-dimensional analysis of the professional culture of such a merchant; the concept of professional space; the organisation of time; and the bearings of his commercial and patrimonial investments. The result of this analysis is an attempt to reinterpret the decadence of Barcelona at the end of the fifteenth century through the notion of work entertained by those involved in commerce, attempting by this means to merge the consideration of economic and cultural matters. It is also a proposal for a model of analysis of professional categories, which on so many occasions have been left to one side because of the preponderance of more traditional questions such as those concerning society, economics or politics.     

先唐时代之宣城：江南奥壤,山水诗都

唐代以前的宣城,走过了由县邑到郡治、由江南西部的行政中心到江南地区的政治腹地与经济沃壤的历程。其间几个关键节点是:楚国置爰陵邑,西汉置丹杨郡,孙吴丹杨郡迁治建业,西晋分置宣城郡,六朝时代之宣城既为近畿要地、又逐渐成长为文化名邦。以南齐谢朓为标志人物的山水诗的创作与影响,既反映了南朝时代宣城的文化特色,也使得宣城成为中国文学史上名副其实的"山水诗都"。

唐代贾耽的地理(地图)著述及其地图学成绩再评价

对唐代贾耽的地理(地图)著述的名目进行辨析,分析了"关中陇右及山南九州等图"、《九州图》、《海内华夷图》之间的关系,以及别录与通录的区别。指出《九州图》、《海内华夷图》是贾耽国图撰修总体事业在不同历史阶段的总称。并从地图学传统、方志学传统入手,探讨了贾耽地理(地图)著述的性质,对其中的地图学成绩进行了重新评价,进而从"近意就实,依稀像真"分析了贾耽地图学的滞后性,指出"古墨今朱"应只是文字注记的区别,并非通过图形绘制表达古今地理要素的差异,由此审视了中国古代地图史上图形绘制与文字注记的关系。     

The looting of the Iraq Museum: Thoughts on archaeology in a time of crisis

Abstract

The looting of the Iraq Museum has been widely proclaimed to be the worst cultural destruction since World War II; some have compared it to the decimation wrought by the Mongol invasion of Baghdad. Others have contended that the damage was wildly exaggerated. Any attempt at understanding the events surrounding the looting and destruction of the museum's collections must examine both what happened and how it was represented to a worldwide audience through the news media. I compare these events with the toppling of a statue of Saddam Hussein in Fardus Square and the burning of major libraries in Baghdad and suggest that their perceived significances for Western audiences stem in large measure from the extent and tone of press reporting. The long-standing coverage by major mainstream news media of Mesopotamian archaeology as foundational to Western civilization may be a prime reason why otherwise pro-(US) government reporting also included some critical coverage about the loss of the museum collections. Such circumstances challenge archaeologists to use media interest to convey more nuanced and ethically responsible views of archaeology to broader publics.
