ELECTROCHEMISTRY AND AUTHENTICATION OF ARCHAEOLOGICAL LEAD USING VOLTAMMETRY OF MICROPARTICLES: APPLICATION TO THE TOSSAL DE SANT MIQUEL IBERIAN PLATE

An essentially non‐invasive electrochemical methodology addressed to the authentication of archaeological lead is described. The method is based on the record of the voltammetric response of nanosamples from the archaeological artefact mechanically transferred to a graphite ‘pencil’ electrode in contact with aqueous buffers. Three diagnostic criteria for authentication are described based on the appearance of: (i) oxidative dissolution signals for trace metals like copper, arsenic, antimony and, often, tin and silver accompanying stripping peaks for lead, (ii) peak potential shifts for reduction peaks for patination products, and (iii) the presence of reduction peaks for PbO₂. The method is applied to the authentication of an Iberian lead plate from the Tossal de Sant Miquel (Llíria, Spain) site using a series of genuine and false pieces from different provenances in the Valencian region (Spain).     

Working in landscape archaeology: the social and territorial significance of the agricultural revolution in al‐Andalus

The agrarian transformations which took place in the Iberian Peninsula between the eighth and the tenth century are essential for an understanding of how al‐Andalus came into being. These developments provided the basis of a social formation which developed into a tributary mode of production. This study is part of a research project that draws inspiration from the tenets of landscape archaeology. Studying historic landscapes as part of the material culture of past societies provides valuable information about cultures and the ways they express themselves in space.     

Studies of the early medieval pottery of al‐Andalus

This paper presents a review of the studies of early medieval (Amiral and Caliphal) pottery in al‐Andalus. It opens with a discussion of the first archaeological and ceramics surveys, including an assessment of their historical and theoretical contexts and their relevance to the developing discipline. After discussion of the contributions and also shortcomings of current approaches, the article closes by sketching the direction of future research.     

七千人大会与领袖接班人问题

研究领袖接班人问题,1962年年初的七千人大会是一个不容忽视的关节点。七千人大会导致毛泽东产生"修正主义要推翻我们"的危机感,引发了他对接班人问题的严重关注;埋下了毛刘冲突的种子,刘少奇的接班人地位开始动摇;林彪在七千人大会上的讲话用心良苦,深得毛心,由此在接班人序列中的地位急剧窜升。     

模拟青铜器样品在典型电解质溶液中的电化学行为研究

为了具体探讨青铜器不同相组织的腐蚀状况,采用电化学测量技术研究模拟青铜器样品在五种典型电解质和模拟土壤溶液中的腐蚀行为。实验结果表明,在氯化钠、硫酸钠、磷酸钠、氢氧化钠、碳酸氢钠以及模拟的土壤溶液中,青铜器组织中的α相比δ相及(α δ)共析体组织更容易发生腐蚀。介质的pH值以及不同离子对青铜器不同相组织的腐蚀行为影响很大。     

《和名类聚抄》中有关"此间"注释的考证

《和名类聚抄》是日本最早的分类体汉和词典(大约成书于公元934年)。这部巨著凝聚了当时词汇的日语读音——"和训",是日本对中国语言文化吸收的活化石。"此间(云)"是其中对"和语"读音注记的一种表述方式。本文拟从"此间"的由来和含有"此间"注解的三种形态及其特征对"此间"的含义进行全面的考察。     

Revolutionary versus Reactionary: Contrasting Portuguese and Spanish Civil-Military Relations during Democratisation

The military is an important factor for the success or failure of democratisation processes. Portugal and Spain provide two paradigmatic cases. Despite their socio-economic, political and cultural similarities, these countries developed very different civil-military relations which significantly impacted their transitions. After having handed power over to a civilian dictator, Salazar, the Portuguese military eventually caused the downfall of his authoritarian Estado Novo regime and steered the transition to democracy. In contrast, the Spanish military, which had helped Franco defeat the Second Republic, remained loyal to the dictator’s principles and, after his death, obstructed the democratisation process. Drawing on primary and secondary sources, this interdisciplinary article contrasts the challenges posed by the military and the policies implemented by the Iberian governments to depoliticise and control it. It shows that the failed coups d’état in these countries helped tighten civilian control and paved the way for democratic consolidation. Using a policy instruments comparative framework, this paper demonstrates that not only the attitudes of the military but also the tools used to keep them under control were substantially different in Portugal and Spain. Historical legacies from the Spanish Civil War, Second World War and Colonial conflicts, as well as contextual factors, serve to explain this variation.     

Analyzing entangled territorialities and Indigenous use of maps: Atikamekw Nehirowisiwok (Quebec,Canada) dynamics of territorial negotiations,frictions, and creativity

This paper highlights the relevance of analyzing entangled territorialities and Indigenous use of maps in order to better understand what Lévy describes in terms of “spatial capital”—the socio-economic dynamics and power relationships maintained and negotiated between the stakeholders interacting within the Indigenous forestland. More specifically, it discusses the entanglement dynamics of land tenures coexisting today within Nitaskinan, the ancestral territory claimed by the Atikamekw Nehirowisiwok. Within Nitaskinan, members of the First Nation negotiate the continuity of their practices, occupation, and use of ancestral hunting territories with state institutions, logging companies, and non-Indigenous members of civil society who have interests in the land resources. All these stakeholders implement different territorial regimes that interact and sometimes conflict. Based on concrete ethnographic examples, the analysis presented here focuses on the compromises, frictions, resistance, and creativity that are part of territorial coexistence between Indigenous and non-Indigenous people.     

The Use of Desert Kites as Hunting Mega-Traps: Functional Evidence and Potential Impacts on Socioeconomic and Ecological Spheres

行业异质性与空间黏性：企业迁移成效的差异及其解释——以英德市产业转移园为例

企业迁移成效的差异是经济区位理论和区域发展政策关注的重要科学问题。区域产业转移实践往往呈现出多个行业的产业转移到相同区域的特征,以及产业转出地和转入地之间对不同行业的空间黏性存在差异,导致区域产业转移效果存在差异和理论解释的复杂性。基于此,本文从企业迁移的微观视角出发,以珠三角地区转移到粤北地区的产业转移园为例,通过行业投产数据的比较和空间盈利边界的理论演绎,分析区域不同行业产业转移效果的差异及其成因。研究表明,企业迁移成效存在行业异质性的差异,这是由于不同行业企业的对转出地的空间黏性大小不同造成的。空间黏性较小的企业比空间黏性较大的企业有更多的空间盈利。
