Looking for circular structures in post hole distributions: Quantitative analysis of two settlements from bronze age England

A statistical procedure is suggested for the analyses of hypothetical round-house plans among post hole patterns. The data are compared with an analogous random scattering of points and differences are noted. Plausible interpretations are contrasted with chance configurations to determine their strength. Single-link cluster analysis and statistical geometry are used. The emphasis throughout the paper is on data analysis rather than hypothesis testing.     

利用高精度计算机断层扫描系统重建青铜器香薰的三维模型

为重建馆藏青铜器香薰三维模型和研究其制造工艺,利用高精度计算机断层扫描系统进行数字成像(DR)和锥束扫描(CT)两种方式扫描香熏,获得其灰度图像,经过图形图像处理,获取表面轮廓三维数据。表面定义和提取后,将数据输入逆向工程软件系统,重建香熏的三维CAD模型。结果表明,获得的点云数据密集均匀,未见扫描盲区;发现香熏存在焊孔和变形;逆向三维重建的香熏CAD模型具有良好的几何相似性。研究提示,高精度计算机断层扫描方法空间分辨率高,精确度高,可以作为一种获取青铜器三维数据的可靠方法。     

The Intentional Use of Lead–tin Orange in Indian Islamic Glazes and Its Preliminary Characterization

We describe the historical appearance, composition and texture of a little‐known orange pigment in 17th‐century northern India. The pigment shares similarities with lead–tin yellow type II, but has between 6 and 7 wt% zinc oxide instead of silica as a minor element in its structure, in addition to the dominant lead and tin oxide. The consistency of its occurrence and composition across several important and highly decorated monuments and relatively wide chronological and geographical ranges of use indicate the controlled and intentional production of this pigment. We propose to use the name lead–tin orange for this material, indicating its similarity to lead–tin yellow but highlighting its independent character and distinct colour.     

Beyond the ICF: Italian network strategies for job placement of persons with disabilities

The Second National Conference on Disability, held in Bari in 2003, took the World Health Organization's International Classification of Functioning, Disability and Health (ICF), adopted by all WHO member states in 2001, as its frame of reference for future action and policies on disability. The ICF broke decisively with the medical model by seeing disability as an interaction between a biological and psychological condition and environmental and attitudinal barriers. Although existing Italian legislation on access to work for persons with disabilities, particularly Law 68/1999 on ‘collocamento mirato’ (targeted placement), anticipated some of the principles and definitions of the ICF, its implementation in practice was often snared in complex bureaucratic procedures and compromised by narrowly medical assessments of impairment and by considerable variations in standard from region to region. In 2009–2011 a pilot project, Progetto ICF4, was launched in 11 regions of Italy. It applied ICF principles, using Social Network Analysis (SNA) to assess the suitability of a work environment in terms of the networks of relations between the different actors involved in it. The way this has functioned in practice is illustrated by a case study of Teramo, one of the provinces in the pilot.     

Hurricane impacts on southeastern United States coastal national park visitation

As a major contributor to local economies, the tourism industry has been greatly impacted by natural disasters. This study demonstrates the association between tourism economies and impacts of hurricanes in the southeastern United States containing coastal national parks, known for attracting a large number of tourists and having experienced hurricanes. In keeping with two longitudinal data methods (i.e. panel logit model and autoregressive integrated moving average), this study focused on the relationship between the (1) duration, intensity, and damage of hurricanes; (2) existing climate conditions; and (3) tourism demand on park visitation during hurricane and tourism seasons. As a whole, the impacts of hurricanes and climate conditions (precipitation, temperature) were found to have a negative effect on tourism demands (park visitation). With regard to the response of tourism economies to natural disaster damage, parks that experienced stronger natural disasters may be closed for a longer period in order to reconstruct facilities or natural/cultural resources damaged by storms. In an attempt to improve tourism-based regional economies, overcome the challenge of natural disasters on tourism economies, and increase opportunities for establishing disaster management, it is necessary to make an effort to allay unexpected damage to tourism-based areas through proactive plans for disaster mitigation activities.     

基于面板模型的城市居民国内旅游消费实证分析

本文通过整理面板数据并构建面板模型,分别以出游率、人均旅游花费与旅游购买力衡量旅游消费,引入虚拟变量区分收入水平与SARS危机的影响,从而揭示了收入对城市居民国内旅游消费的决定作用。模型估计结果表明：第一、对不同的旅游消费指标,收入的决定作用存在差异,其中,旅游购买力与出游率的收入弹性远大于人均旅游花费的收入弹性;第二、与低收入城市居民相比较,高收入城市居民国内旅游的出游率收入弹性减小,人均旅游花费收入弹性增大;第三、SARS对高收入城市居民国内旅游消费的负面影响更大。最后,根据面板数据的描述性统计结果与模型估计结果,从供给角度,建议在全国层次注重发展观光旅游,在旅游目的地层次注重细分目标市场。     

The use of predictive modelling to target Neolithic settlement and occupation activity in mainland Scotland

A central aim of Neolithic studies in Europe is to understand settlement or domestic activity of the first agriculturalists. In Scotland, the continued absence of unambiguous Neolithic settlement or domestic occupation activities on the mainland remains an unresolved issue. It is proposed that areas attractive for settlement and occupation activities may be identified by constructing GIS-based models of sites believed to be related to settlement or occupation activities, including chambered cairns, timber halls, and sites containing pit-digging episodes. Statistical analyses undertaken in this process suggest new insights into the locations of the chambered cairns, timber halls, and pits. Finalised models are constructed and desktop assessments are conducted to examine model performance. Research priorities for improving significant environmental variables driving the current models are identified.     

阿普尔加斯与19世纪英国工人运动的发展

19世纪中期,随着新模范工会在各行业的发展,英国工人运动进入了一个新的历史阶段,在阿普尔加斯等人为代表的新一代工会领导人的努力下,工会不仅成功地克服了1866年谢菲尔德暴行带来的巨大危机,而且在各阶级进步人士的帮助下,推动议会在19世纪70年代相继通过了有利于工会运动的立法,使工会从此成为英国产业制度中一个不可缺少的组成部分。而新模范工会所倡导的自助自制精神、阶级合作和劳资和解的政策,不仅为工会运动的合法化开辟了道路,同时也为19世纪中期英国社会的和谐稳定,经济的繁荣发展提供了保障。
