Evidence of Stress Fracture in a Homo antecessor Metatarsal from Gran Dolina Site (Atapuerca,Spain)

We present the palaeopathological analysis of a right fourth metatarsal (ATD6‐124) recovered from the Atapuerca–Gran Dolina site (Spain). This fossil, ca. 1 Ma, belongs to Homo antecessor, the earliest known European hominin species. The metatarsal exhibits a proliferative lesion on its medial periosteal surface. Periosteal reaction can be the bone response to a wide number of injurious processes. We describe a lesion on the basis of macroscopic and microscopic analyses, including microtomography and scanning electron microscopy. Externally, the osteoblastic lesion presents a highly porotic and disorganised morphology. Internally, we observe a series of micro‐fractures on the compact bone that do not affect the medullary canal. We provide a differential diagnosis and suggest that the ATD6‐124 lesion could correspond to a pedal stress fracture, also known as fatigue or march fracture. Stress fractures have been related to a load increase and muscular fatigue. This type of fracture has been widely reported in the foot of soldiers and athletes, which are usually engaged in strenuous, excessive or prolonged locomotive activities. Despite its high frequency in these groups, stress fractures have not been reported as such in fossil collections, with the exception of a metatarsal belonging to the Sima de los Huesos site (Atapuerca).

鄂、西鄂、东鄂辨证——兼论湖北称鄂之由来

基于考古资料并结合前人研究成果,梳理了乡宁之鄂、沁阳之鄂、随州之鄂、南阳之鄂的地望变迁。西周早期为南控南淮夷、荆蛮,周封鄂于今随州。周夷王时,将鄂迁徙到今河南南阳市宛城区新店乡西鄂故城一带,周代南土防线亦随之收缩。约在春秋早期楚将南阳盆地纳入政治版图之时鄂国已消亡。战国中期前后,西鄂为楚封鄂君之地。垂沙之役后,鄂君东迁大冶鄂王城,始有东鄂。秦及汉初于东鄂故地设鄂县,其后又在南阳鄂国故地设县,因江夏先有鄂县,故称南阳之鄂为西鄂。湖北简称鄂与西周时期随州鄂国或南阳西鄂并无直接关系,而是与行政区划变迁及武昌九省通衢的地位日渐重要有关。武昌有“鄂”之别称,是湖北省简称鄂的直接原因。     

尉迟寺出土陶鬶的启示

史前陶鬶发展的主流看法是起源于海岱地区,然后向周围传播。但是,蒙城尉迟寺遗址出土的陶鬶现象给这种观点带来了难解的课题。本文通过对尉迟寺出土陶鬶的验证,再次肯定了陶鬶应该发源于太湖地区。并且,尉迟寺遗址也是陶鬶发展过程中的关键区域,为陶鬶的传播研究提供了宝贵的资料。     

抗战时期胡适对中日现代化进程的历史反思

本文由胡适对晚清以来中国现代化进程的历史评价、中日现代化历史进程的比较研究两个层面,梳理和阐释了胡适对中日现代化进程问题研究的历史深度和理论贡献。胡适立足于中日两国历史的比较,进而归纳出两种截然不同的现代化反应类型:发散渗透型与中央控制型。在众说纷呈的抗战思想论观中,胡适独树一帜,其在抗战时期初步成型的中日现代化历史比较研究理论模型探讨,有着强烈的时代特征。胡适没有局限于对日本帝国主义侵略战争的一般性揭露,而是通过对长期流传的所谓日本现代化成功论的历史分析,揭示日本社会深层次的文化危机和历史困惑。胡适对19世纪中期以来尤其民国建立后中国现代化进程中所取得成绩的肯定,是其思想复杂性中占主要方面的一个认识;他所归纳的文化冲突的理论及规律模式,与他对近代中国现代化历史进程的阶段性成绩观察紧密关联,也为我们认识近代中国历史的诸多重大事件,提供了一个新颖而独特的历史新视角,其理论价值不容忽视。从胡适所已经尝试的由现代化视角进行中日现代化进程历史比较研究来看,抗日战争与中国现代化进程研究确是一个历史时期已存在的学术主题。笔者认为,此方面学术研究成果的继续挖掘,于当今的抗日战争研究,仍有启发意义。     

Image‐Based Modelling from Unmanned Aerial Vehicle (UAV) Photogrammetry: An Effective,Low‐Cost Tool for Archaeological Applications

The recording and 3D modelling of complex archaeological sites is usually associated with high capital and logistical costs, because the data acquisition must be performed by specialists using expensive surveying sensors (i.e., terrestrial laser scanners, robotic total stations and/or ground‐penetrating radar). This paper presents a novel, low‐cost, user‐friendly photogrammetric tool for generating high‐resolution and scaled 3D models of complex sites. The results obtained with unmanned aerial vehicle (UAV) photogrammetry of an archaeological site indicate that this approach is semi‐automatic, inexpensive and effective, and that it guarantees quality.     

EMERGENCE OF LEAPFROGGING FROM RESIDENTIAL CHOICE WITH ENDOGENOUS GREEN SPACE: ANALYTICAL RESULTS

Leapfrog development is a typical form of sprawl. This paper aims at analyzing the existence, size, and persistence of leapfrogging in a dynamic urban economic model with endogenous green amenities. We analyze whether incoming households choose to settle at the fringe of the city or to jump further away depending on their preferences and the structure of the city. We first provide an analytical treatment of the conditions and characteristics under which a first leapfrog occurs and show how the optimal choice is affected by the size of the city, income, commuting costs, as well as the size of the area where green amenities are considered. We then study how further leapfrogging and multiple urban rings may appear and be maintained in the long‐run equilibrium, and how infill processes take place through time.     

THE EFFECT OF ACCESSIBILITY ON PRODUCTIVITY IN SPANISH MANUFACTURING FIRMS

This paper evaluates the impact of accessibility on the productivity of Spanish manufacturing firms. We suggest the use of accessibility indicators of workers and commodities, integrating transport, land use, and individual components, computing real distances or traveling times using the Spanish full road network. Estimated firms’ total factor productivity is explained as a function of the accessibility indicators and additional control variables. Results evidence the crucial role on firms’ productivity to the accessibility of commodities and to a slightly lesser extent the workers.     

Chemical and mineralogical characterization of Aguada Portezuelo pottery from Catamarca,north-western Argentina: PIXE,XRD and SEM-EDS studies applied to surface pre- and post-firing paints,slips and pastes

Particle-induced X-ray emission (PIXE), X-ray diffraction (XRD), electron microprobe analysis (EDS) and scanning electron microscopy (SEM) analytical techniques were used to characterize surface paints in pre- and post-fired Aguada Portezuelo decorated pottery. Surface paintings in black, white, red, brown, burgundy and ochre were analysed. Major, minor and trace elements were detected by PIXE, whereas XRD and SEM-EDS gave information on the main mineral phases and the characteristic morphology for each analysed pigment. The results obtained indicate that the main colour groups can be easily discriminated by PIXE, and they are characterized by only one pigment for each colour: hematite (red) and manganese mineral oxides (black), respectively, whereas white pigments are characterized by calcite, ghelenite and gypsum.     

尊崇与承继:陈作霖对卢前的影响

中国的传统文化、乡邦文化的魅力,是靠一代代的文化人继承、延续和发展的。陈作霖(可园)是保存近世南京文化的典型代表。民国时期,文学和戏剧史论家卢前对陈作霖的贡献推崇备至,以其为民国初年东南耆硕之魁率,认为陈作霖从历史的废墟和陈迹之中爬梳、挖掘和勾画出江苏和南京的历史文化的面貌,对发掘与整理江苏南京文献居功至伟。陈作霖对故乡南京历史文化的热爱,也影响了卢前的一生。在担任南京通志馆馆长和文献委员会主任期间,卢前主持编纂了26册的《南京文献》,延续了南京文化人对地方文献特别关注的传统。
