Combining growth and level data: An estimation of the population of Belgian municipalities between 1880 and 1970

Economic historians that study long-term changes during the nineteenth and twentieth century are fundamentally restricted by the availability of qualitative data. As a result, researchers are forced to either impute missing data, or otherwise combine datasets in some way. In this article, we demonstrate the versatility of state-space models in addressing these problems. Not only do they enable us to compose large data series of high quality, they also provide a clear estimate of how reliable this data is, allowing any subsequent analyses to take this reliability into account. We illustrate the advantages of a state-space model using the population of Belgian municipalities as a case study. By combining growth and level data, we are able to compute yearly population statistics of over 2600 municipalities from 1880 to 1970.     

L'ANALYSE DES CORRESPONDANCES: UNE AIDE À LA DESCRIPTION DE DONNÉES SPATIO-TEMPORELLES — APPLICATION À L'OCCUPATION DU SOL EN RÉGION WALLONNE, BELGIQUE

L'analyse des correspondances (AC) est une méthode exploratoire d'analyse multivariée destinée à représenter graphiquement et de façon synthétique les lignes et les colonnes d'un tableau de contingence. Dans la présente application, nous considerons un ensemble de tables annuelles qui ventilent la surface de la Région wallonne selon ses cinq provinces et ses classes d'occupation du sol. Ces tables annuelles sont juxtaposées et traitées simultanément par AC, de sorte qu'on peut suivre sur les graphiques l'évolution des provinces et celle des occupations. Grâce à un critère de maximisation de l'inertie temporelle, ces dynamiques sont paticulièrement bien mises en évidence en une représentation toutefois très concise.
Correspondence analysis (CA) is an exploratory multivariate technique used to represent graphically and in a synthetic way the rows and columns of a contingency table. In this application, we consider a set of annual tables that cross-classify the Walloon Region surface according to its five provinces and land-cover classes. These annual tables are juxtaposed and processed simultaneously by CA, so that one can observe on the graphical displays the temporal changes of the provinces and those of the land-cover classes. Thanks to a criterion of maximizing temporal inertia, these dynamics are particularly well emphasized in a very concise representation.     

基于手机信令数据的城市时间活力模式及影响因素研究——以南京市中心城区为例

本文基于手机信令数据从时间维度诠释城市活力的概念,并构建其评价指标体系。研究从活动强度、活动混合度、活动联系强度三个维度测度城市活力,在此基础上通过对一日24小时的城市活力时间序列进行聚类,得出五种城市时间活力模式,并构建计量模型分析社会经济和建成环境对不同时间活力模式的影响。主要结论有：(1)南京市中心城区城市时间活力模式可分为高活力波动型、高活力稳定型、中活力波动型、中活力稳定型和低活力稳定型五类;(2)不同时间活力模式在空间上的分布具有一定规律,高活力波动型时间活力模式多位于区域就业中心与公共服务、商业服务中心附近;(3)影响因素方面,居住人口密度、年龄结构、经济水平、交通区位、功能性质、开发强度均对高活力波动/稳定型街区的形成有促进作用。研究从时间维度扩展了城市活力的研究视角,可为探索城市时空间规划、保障城市高质量可持续发展提供重要参考。     

基于极限学习机的汉阳陵外藏坑遗址温度预测研究

作为我国首座全封闭式遗址博物馆,汉阳陵外藏坑遗址博物馆已积累超过700万条各类监测数据。然而,受限于海量数据挖掘能力,目前研究中存在监测数据利用率不足和预测模型准确率较低的问题,针对这一问题,引入大数据机器学习领域的极限学习机方法对遗址温度进行系统分析和建模预测。研究结果表明,该方法具有良好的大数据发掘和处理能力,能够有效分析温度的变化规律及特征,并对未来温度变化趋势和细节变化特征实现较为准确的预测。本方法的引入可为遗址预防性保护和管理提供参考。     

基于腾讯位置数据的中国城市居民航空出行时空特征

随着中国经济社会的快速发展,航空出行成为居民出行方式的重要组成部分,并影响着城市格局。本文基于2019年4月28日—5月10日国内215个机场的腾讯定位请求数据,分析中国城市居民在工作日和五一假日两个场景下的航空出行时空特征,进而探究其与城市格局的关系。结果表明：①中国城市居民航空出行在空间上,总体呈现东部沿海高于内陆地区,且中部地区相对较低的特点;②在时间上,多集中在工作日,且京津冀、长三角、粤港澳大湾区、成渝等经济发达地区的中心城市更偏向“工作日优势型”,而中部地区及西南部地区的非区域中心城市更偏向“假日优势型”,并呈现以24小时为周期的下降、上升和波动的日变化,与工作日相比,五一假日提前2小时进入波动期,且居民假日航班时间选择更偏向在下午3点和晚上8点前后;③在工作日和假日两类场景下,所呈现的聚类等级分化与其所在城市规模之间关联性较强,在一定程度上接近城市金字塔的规模等级分布特征。     

基于点云数据的秦始皇兵俑头面部特征提取与统计分析研究

考古出土的秦始皇兵俑是秦朝十分珍贵的实物资料,具有重大的历史、科学和艺术研究价值,其“千人千面”的特点更是备受关注,被认为是秦人的真实写照。现代人体测量中,头面部特征因其多受遗传因素作用,少受环境因素影响,被广泛应用于分析各民族之间的亲缘关系。通过采集50个样本的兵俑头部高精度三维点云数据并提取了头面部特征,运用样本相关性分析和数据大小排序的统计分析方法,与现代29个群体或地区头面部特征进行了对比研究。结果显示秦始皇兵俑样本的头面部特征完全各异且高度相关,同时与现代群体或地区的头面部特征差异性较小,定量化地明确了秦始皇兵俑的相关特点。

Intellectual property and the licensing of Canadian government geospatial data: an examination of GeoConnections' recommendations for best practices and template licences

In Canada, Crown copyright permits government to assert control over its works. These Crown rights have often been justified on the basis that government must assert intellectual property rights so as to be better able to control the accuracy, integrity and quality of any information that reaches the public through Crown works. In this article, the authors examine GeoConnections' template agreements for the licensing of government geographic data. They argue that not only is the basis and scope of claims to intellectual property rights uncertain, the objectives of quality control, data integrity and accuracy do not appear to motivate the licence terms. The uncertainty as to the legal basis of the intellectual property claims is significant, as licences of this kind may give support to otherwise weak downstream claims by third parties to copyright in data products generated through the use of geographic data provided by the Crown.     

Burned bone in the Howieson’s Poort and post-Howieson’s Poort Middle Stone Age deposits at Sibudu (South Africa): behavioral and taphonomic implications

Despite a growing awareness of the wide range of information that can be provided by detailed analyses of burned bone from archaeological contexts, such analyses are still relatively uncommon. This paper focuses on the behavioral and taphonomic implications of burned bone from the Middle Stone Age (MSA) site of Sibudu Cave (South Africa), reporting on the analysis of a large sample (>377,000 fragments) of bone recovered from the Howieson’s Poort (HP) and post-HP MSA deposits at the site. Faunal remains were initially sorted into burning categories based on changes in color; microscopic analyses focused on the optical properties of the bone matrix (degree of preservation of the bone structure, reflectance and fluorescence) indicated that the color is a valid indicator of thermally altered bone in the Sibudu assemblage. The association of burned bone with hearths, the intensity of burning damage, and the sheer quantity of thermally altered bone suggests that the bone was not burned primarily as a result of natural fires. We propose that the high incidence of burned bone primarily reflects two types of site maintenance activities: first, the discarding of bone into fire as a means of disposing of food waste (as also argued by Cain [2005, Using burned animal bone to look at Middle Stone Age occupation and behavior. J. Archaeol. Sci. 32, 873–884], for a smaller sample of material from the post-HP and late MSA deposits at the site), and second, the incidental burning of bone on/near the surface during the periodic burning of plant-based bedding. In considering the taphonomic implications of the burned bone, we demonstrate that calcined bone is in fact more heavily fragmented than unburnt or moderately burned bone. Furthermore, cortical preservation was negatively correlated with the intensity of burning damage, which has implications for the study of surface modifications. These results indicate the importance of conducting thorough taphonomic analyses prior to making comparisons between units that show differing degrees or intensities of burning damage.
