A cargo of lead ingots from a shipwreck off Ashkelon,Israel 11th–13th centuries AD

Shipwreck cargo of lead ingots, some marked, discovered off Tel Ashkelon, weighed about four tonnes. C14 analysis of charred wood from an ingot dated it to the 11th–13th centuries AD, Crusader times. Lead isotopic ratios provenanced the ingots to Mont‐Lozère, France. Various aspects of the lead trade are discussed, including: lead sources, extraction, casting, lead in the international maritime trade, weight units in medieval trade, prices, transportation, sale and storage, lead cargo and ballast, reconstruction of the wrecking event, salvage after the vessel was wrecked, Ashkelon as a trading coastal town in the 11th–13th centuries AD, and the possible destination of the cargo.     

基于理性选择理论的“蚁族”居留意愿研究——来自北京市的实证调查

蚁族是否定居在一线城市是基于自身效用最大化的结果。本文使用课题组2016年12月北京蚁族的调研数据,对京蚁地理空间分布进行分析,在此基础上,参照理性选择理论分类标准,从生存理性、经济理性和社会理性三个维度出发,对影响蚁族居留意愿的因素进行实证考量。研究发现,蚁族是否定居北京主要受性别、教育程度、居住状况、社会保障以及社会交往情况等因素的影响,社会理性相较于经济理性和生存理性对蚁族居留意愿的影响更为显著,并从社会空间理论视角对影响因素的显著性原因进行分析,从而为相关政策制定提供参考。     

“Academic War” over Geography? Death of Human Geography at the Australian National University

This article analyses how neoliberal economic policies decide what particular aspects of knowledge are valuable and what are not, and who might be the true holder of that knowledge within the tertiary education system. This assessment leads to some disciplines being seen as less valuable to the system. It argues that the more recent “academic wars” in geography are over the very concept of the university and its role in the contemporary society, what comprises useful knowledge, and who comprises the authoritative figure in the production and distribution of that knowledge. Gender of the geographer therefore becomes a crucial element that determines “authority” in the production of geographical knowledge. To substantiate this argument, the paper takes up the important task of analysing the complex career trajectory of geography within the Australian National University (ANU), the department that was gradually reduced leading eventually to its unfortunate closure in 2009.     

Sustained Organizational Influence: American Legislative Exchange Council and the Diffusion of Anti‐Sanctuary Policy

Building upon existing literature, we offer a particular model of network policy diffusion—which we call sustained organizational influence. Sustained organizational influence necessitates an institutional focus across a broad range of issues and across a long period of time. Sustaining organizations are well‐financed, and exert their influence on legislators through benefits, shared ideological interests, and time‐saving opportunities. Sustaining organizations' centralized nature makes legislators' jobs easier by providing legislators with ready‐made model legislation. We argue that sustaining organizations uniquely contribute to policy diffusion in the U.S. states. We evaluate this model with a case study of state‐level immigration sanctuary policy making and the role that the American Legislative Exchange Council (ALEC) played in disseminating model legislation. Through quantitative text analysis and several negative binomial state‐level regression models, we demonstrate that ALEC has exerted an overwhelming influence on the introduction of anti‐sanctuary legislative proposals in the U.S. states over the past 7 years consistent with our particular model of network policy diffusion. Implications are discussed.     

Cooptation of ENGOs or Treadmill of Production? Advocacy Coalitions and Climate Change Policy in Finland

Corporatist Nordic welfare states are largely thought to have exemplary environmental policies. Finland, however, was labeled “a failing ecostate” by a recent study owing to its weak climate change policy. Why is Finland different? We use data from a survey of organizations belonging to the Finnish climate change policy network to investigate two alternative explanations related to policy networks. According to the Cooptation Thesis, inclusive corporatist polities, where environmental NGOs (ENGOs) have support from and access to the state, formulate less ambitious policies because environmentalists moderate their views to secure state funding and political access. Second, according to the Treadmill of Production Theory, the decisive feature of Nordic corporatism with regard to environmental policy is the tripartite system linking business interests, labor unions, and the state in a coalition that prioritizes economic over ecological values. The results indicate that the ENGO Coalition is the least influential, least resourceful, smallest, least linked to the others, and not particularly moderate. The Treadmill Coalition is the most influential, most resourceful, second largest, well linked to the state, and least ecological in its beliefs. Thus, of the two policy network explanations, the dominance of the Treadmill Coalition rather than cooptation of ENGOs gets support.     

A Comparison of Two Methods for Recording Entheseal Change on a Post‐Medieval Urban Skeletal Collection from Aalst (Belgium)

This research compares two current methods for recording bony changes at muscle attachment sites, called entheseal changes (EC); the Mariotti method and the Coimbra method, to evaluate the concordance and comparability of results in a post‐medieval skeletal collection from Aalst, Belgium (n = 116). For both methods, the EC scores produce broadly similar patterns, are symmetrical and differ between age groups. Statistical differences between the upper and lower limb and the lower limb of males and females only occur in the Mariotti method. With careful consideration of the influence of different EC score ranges, the results from the two methods can generally be compared.     

Contact tinning: A millennia‐old plating technology

Tinning copper and copper alloy objects by putting them into (electrical) contact with metallic tin in a boiling aqueous solution of potassium hydrogen tartar is a very old technique, but is nowadays almost forgotten. It was possibly invented by the Gauls and used intensively until the 20th century. This paper first briefly recounts the history of this galvanic process. To understand better the parameters influencing the thickness of the coat and thus to reconstruct this ancient technique, laboratory tests were undertaken by varying a series of parameters. The results are then presented with a short interpretation.
