Marine Data,Access, and Interoperability: Two Case Studies of English National Records

Abstract

The aim of this paper is to discuss the long-term management of marine historic environment archives, focusing on the comparison of English Heritage’s National Record of the Historic Environment (NRHE) with the United Kingdom Hydrographic Office (UKHO) as case studies.

Within marine (and terrestrial) contexts, archaeological archives are unique records of survey, excavation, and associated research of the historic environment. They are a resource which allows understanding of the human past to be developed, reviewed, and reinterpreted as new data is gathered. As such, they are significant for research, development-led studies, education, outreach, and public enjoyment. At a time when there is a significant focus on data from the marine environment, both within the UK and more widely across Europe, this paper puts forward some initial recommendations to enable further interoperability between these two key national datasets.

Analysis of these datasets highlighted some interesting points, including the quantification and qualification of the scale of discrepancies between data providers (NRHE and UKHO), and how these can be overcome to allow comprehensive, reliable, and accessible data on which to base long-term planning, decision-making, and resource management. This will ensure a consistent approach, enabling the successful long-term management of historic environment archives, and making historic environment data readily accessible to the wider public.     

基于手机数据的西部城市居民出行特征研究——以西宁市为例

基于手机轨迹数据系统的定量分析了西宁市不同群体的出行特征差异,通过定义移动距离、回转半径、出行频次和停留位置个数来定量居民的出行特征,分析不同性别、年龄段、工作日和休息日西宁市居民的出行差异.研究发现:①不同年龄群体出行行为差异显著,其中31-40岁年龄段居民的出行需求最为强烈,大于60岁的老年人出行需求最小;②男性在...     

新型工业化视角中的青海轻工业发展

作为自然矿产资源相对富足的省份,青海产业政策的选择应以优势资源开发为主线。但近些年来工业结构中轻、重工业比例失调日益严重,这必然影响青海省实现工业化的速度和质量。本文试图从新型工业化的视角来分析当前青海省轻工业发展中存在的问题,进而提出发展轻工业的几点建议。     

中国旅游类上市公司经营绩效影响因素研究——基于公司治理视角和非均衡面板数据的分析

本文以中国旅游类上市公司为研究样本,利用其2004～2009年的非均衡面板数据建立计量经济学模型,采用混合最小二乘法对影响我国旅游类上市公司经营绩效的关键性公司治理因素进行实证检验。研究表明,旅游类上市公司的公司治理对其经营绩效具有显著影响。股权结构中管理层持股比例、第一大股东持股比例、第一大股东性质和前五位股东持股比例的平方和,以及第一大股东持股比例与第一大股东性质的交互项与公司经营绩效显著正相关,董事会特征中董事会规模与公司绩效显著正相关。     

我国城市化与经济增长的因果关系研究——基于1978-2007年东、中、西部、东北地区面板数据

本文选取1978-2007年中国30个省市的面板数据,运用面板单位根检验、面板协整检验及误差修正模型对我国城市化与经济增长的因果关系进行了检验。实证结果表明:从全国来看,城市化是经济增长的长短期原因,但经济增长是城市化的长短期原因均无法得到证实;东部地区的城市化与经济增长的长短期均互为因果关系;对于中、西部、东北地区而言,城市化是经济增长的长期原因,但不是其短期原因,长短期内经济增长都不是城市化的原因。     

Reflections on Collaborative Archaeology and Large-Scale Online Research Infrastructures

ABSTRACT

The Archaeology Data Service (ADS) is an archive working at a national level in the UK, ensuring that archaeologists have access to high quality and dependable digital resources, including openly licensed legacy data for reuse. The ADS acts as a metadata aggregator for archaeological data held by larger heritage agencies and smaller regional organizations and participates in international aggregation infrastructure projects such as ARIADNE, which allows users to access archaeological resources held in many countries from a single interface. Large-scale infrastructures can facilitate the building of long-term, complex relationships and active collaborations, not just technical solutions. This paper reflects on the roles of stewardship and equity within ARIADNE and the ADS, two large-scale online research infrastructures, and how these types of infrastructures may help to create a more collaborative archaeology, including lessons learned, challenges and opportunities, and thoughts for the future.     

What are patterns in the humanities?

ABSTRACT

This paper is concerned with patterns in past human behaviour, what they are, and how this relates to the detection of patterns in data by means of computation. Theorists have not given patterns the attention they deserve. Therefore it is far from clear what patterns are and to what purpose scholars may use them. This paper presents eight propositions on patterns which hold true for patterns found ‘by hand’ and patterns found ‘by computation’. One such is that a pattern is discernible in behaviour when we subject it to the intentional stance, as the philosopher Daniel Dennett argues. Here behaviour is part of an intentional system. This paper’s argument is that the patterns found ‘by computation’ too are part of an intentional system. To substantiate this claim this paper discusses two important examples of detecting computational patterns in the domain of the humanities.     

基于手机数据可靠性分析的旅游城市功能空间识别研究

随着移动通信和移动互联网的普及,带有地理空间信息的“大数据”受到人文地理学者的关注。本文关注手机移动数据的旅游研究价值,以张家界市武陵源区、慈利县为例,首先分析了通信公司漫游用户数、基站网流量和话务量代表实际游客量的可靠性程度,然后探讨了漫游用户数波动对大尺度行政区的功能空间反映,最后挖掘了网流量波动对小尺度基站区的功能空间识别。结果显示,漫游用户数仅在旅游区对实际游客量具有可靠性,基站网流量比话务量的可靠性更强;漫游用户数在旅游区的波动幅度更大;基站网流量的空间因子分析识别出日常居住区、重点旅游区等功能空间。     

SPATIAL AUTOCORRELATION and EIGENFUNCTIONS OF THE GEOGRAPHIC WEIGHTS MATRIX ACCOMPANYING GEO-REFERENCED DATA

Gaining a better understanding of spatial data and a deeper meaning of spatial statistical results gleaned from geo-referenced data requires a more complete knowledge of properties of the underlying geometry. This paper addresses these two topics by further investigating important geometric features of spatial data. The importance of this work is expressed in the geographic information system literature regarding representations of geographic space, as well as various geographic literatures concerned with spatial statistical modelling. Answers to three questions are obtained here. One asks whether or not those eigenvectors associated with the three largest eigenvalues of a binary geographic weights matrix have natural interpretations. A second question asks whether or not the eigenvalues of a geographic weights matrix prove useful in understanding the sampling distribution for spatial autocorrelation in a given geographic landscape. A third question addresses the issue of spatial autocorrelation components of geo-refer-enced phenomena. The analysis summarized in this paper documents responses to these three questions. Empirical evidence is gleaned from both Canadian urban census tract data and the square tessellations of remotely sensed data. Afin ?obtenir une meilleure compréhension de données spatiales et un sens plus approfondi de résultats statistiques spatiaux découlant de données spatialisées, il faut une connaissance plus complète des propriétés de la géométrie sous-jacente. La présente étude porte sur ces deux sujets en étudiant plus avant des caractéristiques géométriques importantes des données spatiales. La pertinence de ce travail est confirmée par la littérature sur les systèmes ?information géographique concernant des représentations de ?espace géographique, ainsi que par divers courants de la littérature gégraphique portant sur la modélisation statistique spatiale.
