Satellite radio posed a new question for Canadian policy-makers: How to take advantage of a transnational radio service while ensuring cultural identity was not lost within channel offerings that are predominately American. Comparing the initial licensing of satellite radio in Canada (2005) to the merger of the services (2011) and the post-merger license renewal (2012) highlights a shift in the spatial understanding of satellite radio, from being determined by a satellite’s footprint to that of what I call ‘cultural lifelines,’ the various mobile devices and services that enable one to maintain connection to cultural content. Alongside shifting spatial considerations of satellite radio, Canadian content has increasingly been packaged as a brand or genre, catering to fragmented taste preferences and individual, mobile listening practices.  相似文献

景德镇御窑遗址出土的15世纪中叶青花方胜纹绣墩,体量较大,器形特殊,出土时破损和缺失严重,修复难度较大。本研究通过分析传统考古修复中石膏作为补配材料的局限性,利用3D扫描打印的优势,设计采用新颖的高强度透明树脂取代传统修复补缺材料,并且结合特制的加固装置完成对大型青花绣墩的考古修复,满足了后期研究与展览的需要。本研究提出了具有一定实践意义的3D打印补配大件异形陶瓷器的修复技术路线。  相似文献

经济全球化背景下,国际"贸易-交通-旅游"(3T)互动日益增强。采用1982-2011年时间序列数据,分析国际贸易、交通和旅游总量的发展历程,从进、出口分量视角考察三者相关关系,运用最小二乘法构建回归方程。结果发现:①30年来国际贸易、交通和旅游的发展呈持续增长态势。国际贸易和旅游日益重要。②国际贸易、交通和旅游增长过程具有同步性,表现为波动周期同涨同落。③所构建的回归方程决断系数R2均在0.99以上,国际贸易、交通和旅游存在显著相关性。国际货运与国际贸易,国际客运与国际旅游之间具有确定、直接的因果关系;国际贸易与国际旅游的因果性尚待探究。  相似文献

In this paper, the characterization of Roman amphorae from the Porto dos Cacos (PC) and Quinta do Rouxinol (QR) workshops, in the Tagus estuary, dating to a period between the 1st and 5th century AD was carried out on the basis of instrumental neutron activation analysis data on 260 amphorae fragments, together with mineralogical compositional studies obtained by X-ray diffraction.  相似文献

In the last few years virtual anthropology has been used to solve different problems that could not be properly addressed using a traditional anthropological approach. Mainly when dealing with mummies or embalmed bodies, the virtual approach is the only solution to carry out a detailed analysis of the skeleton without jeopardizing the integrity of the physical remains.  相似文献

本文采取就业密度分析方法,对南京市区就业空间布局进行实证研究。在南京市区现有11个区的基础上将南京市区划分为159个研究单元。依据2005年南京市1%人口抽样调查资料中"区县层面"分行业就业数据,以及2006年南京市用地现状图,修正匹配得到各个研究单元制造业、服务业、商业金融业及总的就业密度值。并运用Arcgis软件对就业密度值进行核密度分析以及3D模拟,分析南京市区制造业、服务业以及总就业的空间布局特征及原因机制。  相似文献

The Central Anatolian Volcanic Province (CAVP) in Turkey preserves widespread deposits of Quaternary tephra, presently associated with a small but growing number of Paleolithic archaeological sites. We use multivariate analyses of the abundances of a suite of nine major and minor element oxides determined by electron probe microanalysis. From these data, we construct a classificatory model for correlating distal tephra to one of five volcanic edifices or eruptive phases within the CAVP. Application of this model to distal deposits of primary tephra-fall and reworked tuffaceous sediments from the archaeological sites of Körkuyu and Kaletepe Deresi 3 indicates Late to possibly Early Pleistocene ages for the artifact assemblages there, and provides a fundamental tephrostratigraphic framework to examine spatial and temporal variation in hominin behavior comparable to that of other regions, such as eastern Africa.  相似文献

Clovis points are the principal diagnostic artifacts of a Clovis complex that spread across North America between ca. 11,050–10,800 radiocarbon years before present. Clovis may be the best documented Paleoamerican culture in North America, but much remains to be learned about the movement and interactions of Clovis peoples. Similarities among Clovis points from geographically diverse locations have led some researchers to suggest that a uniform projectile point technology existed across North America during Clovis times. Others have rejected this idea, proposing local and independent technological adaptations to different regional environments. To investigate these ideas, we used digital morphometrics to analyze 50 Clovis points from nine different contexts. First, 3D surface models of the points were created with a portable laser scanner. Next, these models were digitally cross-sectioned through both faces, yielding two-dimensional isoheight contours of flake scar patterns that reflect the original reduction techniques used to shape the projectile points. In the final step, the contours were transformed with elliptic Fourier analysis into Fourier coefficient series, and patterns of variation and symmetry were explored with principal components analysis. When compared to modern Clovis point replicas made by an expert knapper, the flake scar contours of the ancient Clovis points showed little morphological variation and a large degree of bifacial symmetry. Our results support the existence of a widespread standardized “Clovis” knapping technique, most likely transmitted through direct interaction between knappers from different groups.  相似文献

This work describes the procedures, the different techniques and the pipeline used for creating a digital framework that should assist the Superintendence of Pompeii in the digital reconstruction, classification, management and visualisation of archaeological finds inside an advanced 3D web-based repository of reality-based data. Specific topics have been focused on the quality assessment procedures adopted to ensure consistency and reliability of data throughout the whole 3D models acquisition and pipeline creation, as well as on the particular semantic reality-based structure adopted to develop an information system into a knowledge one. The main purposes of our framework have been the usage of 3D digital models as a restitution of the real object and as a metaphor for navigating through the data; 3D models were used as archaeological cognitive systems and developed as a collection of structured objects, identified through a precise terminology that allows to easily extend the concept of 2D GIS to 3D GIS. In addition, the system was developed as a scalable application that allows the use of the same database by different users, simply filtering the data according to the specific requirements, and can operate both as standalone and web-based application.  相似文献
