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.     

Identification of Green Pigment Used in Persian Wall Paintings (ad 1501–1736) Using PLM,FT–IR,SEM/EDX and GC–MS Techniques

The technique of oil painting was introduced to Iran via a cultural exchange with Europe in the Safavid period (ad 1501–1736). Since the first attempt at scientific conservation of wall paintings in Iran in the 1960s, the nature of green pigment used in Persian wall paintings has not been clear, although work on contemporary miniature paintings has identified malachite and verdigris. PLM, FT–IR, SEM/EDX, GC–MS and the study of contemporary historical treatises of the Safavid period were the main tools used in the present study to identify the green pigments in Persian (oil‐based) wall paintings. Eight samples taken from the two famous Safavid buildings, Chehel Sotoon Palace and the Sukias House in Isfahan, were analysed. Here, the identification of copper‐based pigment and of verdigris in oil as oleate amends the existing knowledge of the green pigment used in these paintings. It also suggests that oleate was introduced to Persian artists via the European influence on Persian painting as a result of cultural exchange in the Safavid period, when the technique of Persian painting changed from tempera to oil painting. However, as verdigris in oil and resin can appear as oleate over time, it is unknown whether the Persian artists did this deliberately or accidentally.     

Playing Politics with Sex Offender Laws: An Event History Analysis of the Initial Community Notification Laws across American States

Despite a decline in crime rates, the 1990s witnessed extensive media coverage of several high‐profile stranger abductions and murders of children. State legislators' swift response to the public's growing fear of sex offenders with the adoption of sex offender registration and notification (SORN) laws raises questions about the role of politics. Punctuated equilibrium theory and the diffusion of innovation jointly provide a context to conduct an event history analysis to assess the extent to which politics enhanced legislative responsiveness to public opinion in SORN policymaking. Contrary to the commonly held belief that attributes legislative interest in SORN to salient crimes against children, the results suggest that factors such as the percentage of a conservative population, district‐level competition, and state innovativeness accelerated the diffusion of innovation of the laws.     

Avoiding Blame—A Comprehensive Framework and the Australian Home Insulation Program Fiasco

It is widely acknowledged in the literature that the study of blame avoidance behavior (BAB) exhibited by public officials is scattered and unconcentrated, and that, for the most part, it neglects both contextual factors and comparative research. These deficits inhibit the production of the kind of generalized findings necessary to better understand potential consequences for the policy process and the workings of political systems. We address these deficits by developing a framework that takes stock of blame avoidance research, clarifies the explanatory potential of contextual factors, and allows for a systematic context‐sensitive cross‐case analysis. For illustrative purposes, the framework is applied to the Home Insulation Program in Australia as a critical case. This case reveals the explanatory potential of contextual factors for the understanding of BAB and the consequences thereof. We conclude by stating the advantages of our framework and explain how it can be used for comparative research.     

宫殿而林壑——乾隆皇帝乐寿堂与颐和轩的陈设理念

根据档案记载,紫禁城内乐寿堂院中设有山子,山子仿清漪园乐寿堂前的"青芝岫",园林中的陈设被搬到了宫殿里。本文以此为出发点,对乐寿堂陈设及其理念作了详细考证,此外作者对乐寿堂和颐和轩的对联加以深入分析,厘清了春与仁、与寿、与山之间的关系。揭示了乾隆皇帝意图通过宫殿园林化实现长寿的终极目的。     

Spaces of violence: A typology of the political geography of violence against migrants seeking asylum in the EU

This paper, based on research conducted with asylum seekers in three European Union (EU) member-states, examines the connections among various forms of violence against forced migrants in different state settings. Because violence that is produced within states is not uniform and often transcends borders, understanding how it varies across different geographical settings illustrates the complexity of the risks that migrants face. This paper presents a typology that examines interconnections between the production of various forms of violence and the complex spaces that constitute irregular migration into the EU to better understand these multifaceted factors and why we can anticipate certain forms of violence in a particular space. It also fosters future avenues of research as it provides a foundation for greater collaboration and advocacy to expose and rectify hierarchical imbalances of power and actors responsible for such violence.     

胡家草场汉简与尹湾汉简数术文献中的“刑德行时”

荆州胡家草场12号汉墓出土竹简《五行日书》按端、令、罚、刑、德五时占测为事、初病、生子诸事项的吉凶。这篇文献与尹湾汉墓出土的《刑德行时》大体属于同一文献的不同版本,两相比照,有助于加深对其文本源流、内涵的理解和认识。     

唐玉门关地望新探——基于历史文献与考古遗存互证

在实地调查的基础上,根据传世典籍和出土文献的记载,结合年代测定、考古发现和遥感影像资料,通过空间分析,作者认为唐玉门关和墨离军驻地应在河西走廊西段的常乐故城,即今瓜州县“六工古城”遗址。这里是丝绸之路的交通枢纽,是西域出入口的重要关卡,亦即北魏时期新开伊吾道的起首。唐代玉门关地处疏勒河和榆林河下游洪积冲积扇缘的古绿洲,地貌和水资源等地理环境因素是制约关城选址的基础条件,而政治、军事等人文地理因素则是决定玉门关时空变迁的关键。     

出土墓志与东魏北齐邺京行里制度探析

东魏北齐邺京里坊的设置沿袭北魏洛阳里坊制度,文献记载往往以里或乡里形式称谓居住地。然而有4方东魏北齐时期墓志,志文记载墓主的居宅异于常例,为某行某里,或某行某坊。通过对墓志时代及墓主身份等因素的综合研判,并结合史书记载,可知东魏初至北齐末,某行某里(坊)是邺京里坊称谓的一种常用格式。"行"的称谓源自邺京行经尉制度,行名与里(坊)名的连用,是基于城市治安管理角度所产生的隶属关系的呈现,在名称上反映了某行区域内里的管辖情况。且行名与里名存在一定关联,将行名与里名对照,可知邺京部分行名与里名相同。     

Editor’s Note

Most previous studies have held that the system of Tubo gaoshen (an honorary identity mark) was an imitation of a similar system in the Tang dynasty, referring to the latter’s official costume decorations for its stratified office-holders. These studies have not given due attention to the characteristics of the title itself. From the perspective of the change of the Tibetan name and based on existing research results and historical records in both Tibetan and Chinese, this article tries to offer a new understanding and preliminary discussion on the development of Tubo gaoshen and several related issues. We find that there are two paths in the evolution of its name: One is from Sug to Yi Ge or Yig, the other is from Yig tsang to Yig tshangs. The former is used to denote a concrete gaoshen and can be added as a prefix while the latter denotes the abstract idea of gaoshen and no attribute can be used before it. When the two are used together, the latter is used before the former, such as in: yig tshangs pa ni zangs kyi yi ge gtong/ (As to the gaoshen [yig tshangs], [he] is awarded a bronze yi ge).
