“Thank heavens for the lease”: histories of shared ownership

Drawing on and developing Kingdon’s multiple streams analysis, this article examines the development of one aspect of the UK’s low cost home ownership programme: shared ownership. We demonstrate how key human and non-human policy entrepreneurs were able to set the agenda from 1973–1983 in favour of shared ownership; they neutralized the alternatives, while retaining some of their instruments; and solved a number of early problems by bringing key players into the programme. Our data-sets include a range of archival material and elite interviews. The policy entrepreneurs included John Stanley (who was the housing minister in the First Thatcher government), the National Federation of Housing Associations, and the Building Societies Association. Our development of the multiple streams analysis is to argue that documents, including the lease, act as policy entrepreneurs in their own right. The lease was central to the development of shared ownership and its transformation into a model lease enrolled other organizations, most critically the building societies.     

Homophily horizons and ethnic mover flows among homeowners in Scotland

Abstract

This article analyses mover flows in Glasgow and the role of ethnic homophily, the tendency for movers to be drawn to areas with similar ethnicities to their own. We look at how homophily affects the spatial relocation patterns of homeowners in Glasgow from Scottish, Indian, Pakistani and Chinese descent, and focus on the extent to which homophily extends beyond the immediate locality to surrounding neighbourhoods. Our interest is in estimating the “homophily horizon” – how far the gaze of homophily reaches in mover location decisions. Using a simple Schelling-type theoretical model, we argue that homophily horizons are potentially important in shaping the long-term social structure of cities as they may profoundly affect how potent the overall sorting tendencies of the housing market are in driving segregation. In principle, the more distant the homophily horizon, the more quickly the housing market will tend towards segregation, other things being equal. We adopt Folch and Rey’s use of the local centralization index to capture the influence of surrounding neighbourhoods in shaping mover flows and neighbourhood dynamics. Our estimation combines ethnic mover flows derived from surname analysis of house buyers from the house transactions recorded in Registers of Scotland data. Our results show that the presence of the own ethnic group in the local surroundings is important for explaining mover flows, and that homophily is a local phenomenon.     

Protection through property: from private to river-held rights

ABSTRACT

This article explores how private owners can protect bodies of water through private property rights. It compares the use of conventional property rights in the Netherlands and New Zealand with a novel approach whereby a New Zealand river owns itself.     

Institutional diversity and safe drinking water provision in the United States

In the United States, community water systems are not only numerous but also diverse. Nonetheless, operational scale and public versus private ownership have dominated the understanding of safe water access, leaving underexplored many other factors related to governance. Applying insights from the Institutional Analysis and Design literature, we create and analyze a dataset of California's water systems classified into 26 structural types associated with distinct governance institutions. We document differences in the number of Safe Drinking Water Act violations among these types and demonstrate their relevance for implementing solutions targeting non-compliance. Advancing equitable access necessitates greater attention to organizational structure and institutional diversity in drinking water provision.     

企业社会责任对跨国并购绩效的影响——基于沪深A股上市企业的实证研究

为了帮助我国企业在跨国并购交易中更好地应对因企业社会责任表现所引起的跨国并购风险，平衡好经济利益诉求与社会责任的履行，论文以2009—2017年沪深A股上市公司109起成功的跨国并购事件为研究对象，基于利益相关者理论、社会契约理论与委托代理理论，研究了企业社会责任对于跨国并购绩效的影响，同时考虑了企业所有制、行业一致性和跨国并购经验的调节作用。采用多元回归模型的实证结果表明：1）企业社会责任对跨国并购绩效存在显著的正向影响；2）企业社会责任与跨国并购之间的正向关系受到国有属性与跨国并购经验的负向调节；3）当并购双方属于同一行业时，行业一致性会显著促进企业社会责任对跨国并购绩效的正向影响。建议企业主动披露企业社会责任履行状况并引入国际通行标准，也可借助国际公关公司制定企业社会责任战略。以上研究结论对中国企业履行社会责任方面具有一定的指导意义，同时也为跨国并购绩效的影响因素研究提供了新的理论视角。     

某铁矿隔水护顶矿柱厚度计算及安全影响预测

科学合理地确定矿山隔水护顶矿柱安全厚度是矿山安全生产的前提条件，为保障某铁矿地表民房、道路等建（构）筑物安全，防止矿山开采过程中产生的导水裂隙带贯通第四系含水层，采用荷载传递交汇线法、K.B.鲁别涅依他估算法和冒落带、导水裂隙带高度估算法3种理论分析方法对隔水护顶矿柱厚度进行计算，并利用数值模拟手段对留设隔水护顶矿柱后的开采过程安全影响进行了分析，对理论计算结果进行了验证。3种理论计算方法得出的隔水护顶矿柱厚度分别为14.3～17.3 m、17.5～31.4 m和41.8～57.4 m，推荐隔水护顶矿柱留设厚度为60 m。通过数值模拟分析得出，在留设60 m厚的隔水护顶矿柱的基础上，开采区域和隔水护顶矿柱位置产生的最大拉应力约0.47 MPa，矿山开采不会对隔水护顶矿柱造成破坏；地表产生的最大水平位移约5.8 cm，最大垂直位移约26.5 cm，最大倾斜为1.70 mm/m，最大曲率为0.20 mm/m2，最大水平变形值为0.70 mm/m，满足相关规范要求，预测矿山开采不会造成地表建（构）筑物破坏。     

一种新型包装专用蜡的研制

为了根据某瓦楞纸箱生产厂的实际生产条件制备一种耐热、耐低温、防水、透气等性能优异的包装专用蜡，将58号全炼蜡和70号微晶蜡混合物作为基础蜡料，分别考察添加剂、助剂、抗氧剂等对基础蜡料滴熔点、运动黏度及外观等的影响，确定了最佳制备配方：合成蜡、添加剂B、助剂1、助剂2、抗氧剂加入量（w）分别为基础蜡料质量的9.8%，6.5%，1.5%，2.1%，0.1%。在温度为160 ℃、时间为30 min、搅拌速率为200 r/min条件下制备的包装专用蜡具有熔点高、黏附性强、光泽性好的优点，满足该瓦楞纸箱生产厂的质量和外观要求。
