This paper analyses reform of the law of wages arrestment in nineteenth- and twentieth-century Scotland to examine the spatial nature of the 'regulatory dilemmas' faced by the state in legal interventions in a spatially heterogeneous context. Though this reform was an example of how the nineteenth-century British state sought to regulate the spaces of everyday life, the analysis shows that law-making processes are the outcome of complex tensions between and within the state and legal systems. In these processes, local legal cultures, tensions between systems of common and statute law and the complex geographies of social life play important roles in shaping the conjunction of space, place and law.  相似文献

The social geographies of people with learning disabilities, one of the most marginalized groups in society, have largely been ignored. The paper explores these hidden geographies through the interpretation of narratives of people with learning disabilities in Scotland, within a social policy framework of social exclusion and inclusion. The paper interprets the experiences of being excluded from and included within mainstream socio-spaces, and the safe spaces that many people with learning disabilities have formed for themselves in between the positions of social exclusion and inclusion.  相似文献

Two major fluvial terrace surfaces, and four less significant surfaces, are identified by aerial photographic interpretation, field mapping and levelling on one c. 2 km long reach of the upper Bowmont Water, an upland stream draining the northern Cheviot Hills, Scotland. The oldest terrace surface remains undated. Cartographic, radiocarbon and palynological dating suggest that later terraces formed very recently, within the last 250 years, with the most prominent terrace fill having aggraded in the 18th century. Incision below this terrace surface is dated to approximately the end of the 18th century, correlated with channel trenching at other sites in the region. Detailed palaeoecological and documentary evidence is used to examine whether climatic or land-use changes might have instigated aggradation, and a link with increased precipitation and flooding during part of the ‘Little Ice Age’ is suggested.  相似文献

鄂东北鹰咀山锰矿床地质特征及找矿标志   总被引:1,自引:0,他引:1       下载免费PDF全文
鹰咀山锰矿床产出在桐柏—大别造山带中,目前已发现有4条锰矿(化)体,其产出受控于红安群黄麦岭组和七角山组。本文基于矿区锰矿勘查工作和室内观察、测试研究相结合等手段,对研究区含矿岩系(建造)特征、矿体及矿石矿物特征、成矿过程和找矿标志等方面进行了分析探讨。结果表明:鹰咀山锰矿为沉积变质型矿床,锰矿(化)体主要赋存在黄麦岭组云母石英片岩夹硅质(有时含少量泥质)大理岩建造的岩性段中;矿石类型主要为片岩型锰矿石和大理岩型锰矿石,矿石中锰矿物主要为硬锰矿、软锰矿、菱锰矿、锰白云石和黑锰矿等;初步认为锰矿的形成经历了沉积、变质改造和次生氧化富集的成矿阶段;含锰硅质大理岩和含锰云母石英片岩可作为该地区锰矿的典型找矿标志,该标志对鄂东北地区锰矿找矿具有重要意义。  相似文献

利用探空观测资料及NCEP再分析资料,统计2000-2014年东北高纬度地区霾发生时的环境气象条件,并进行对比分析。结果表明:风垂直切变、地表风速、假相当位温垂直差、逆温强度、混合层高度、K指数、A指数、理查森数和扩散系数等指标和霾发生与维持关系密切。对于东北高纬度地区而言,500hPa与850hPa水平风垂直切变低于21m/s,地表风速在6m/s以下,理查森数大于0.3,逆温强度大于-0.9℃/100m,假相当位温垂直差大于-3K,混合层高度低于1000m,K指数和A指数低于对流天气发生时的经验阈值的情况下,大气垂直和水平方向都不利于污染物扩散,有利于霾的产生与维持。探空资料与再分析资料对应各统计指标在数值上具有较高一致性,特别是极值以外的部分,二种资料计算的指标具有显著的相关关系。对于东北高纬度地区,再分析资料可以代替探空观测资料进行环境参数分布和阈值的统计分析。  相似文献

Marine spatial planning (MSP) is the leading tool for managing human activities at sea. It is designed to assist in decision making for marine resource access and use by considering the actions of those using the resources, interactions between these groups, and their cumulative impact on the natural environment. Being informed by ecosystem based management, MSP recognises that socio-natural systems are complex and that stakeholder and public input are key components of well-informed decision making. Therefore, MSP is rooted in the principles of good governance, including those of participation and transparency. This paper considers MSP processes in Scotland's inshore waters in the context of these good governance principles. The focus is on the institutional arrangements that allow stakeholders and the public to contribute to planning Scotland's seas and coasts. Whilst acknowledging the significant challenges faced by planners, and the work conducted so far, this research suggests that improvements could be made in how – and when – engagement takes place. It appears that at an early stage of introducing MSP in Scotland powerful stakeholders shaped the images, values and principles that guide it, and that including a broader range of actors early on might positively affect the legitimacy and acceptance of MSP in its later stages. The current institutional arrangements do not appear to allow for this. Ultimately, MSP in Scotland is in danger of institutionalising – and thus legitimising – existing power relations between marine resource users, and it does little to level the playing field.  相似文献

The glacial deposits at the Boyne Bay Limestone Quarry near Portsoy, a key Quaternary Site of Special Scientific Interest, comprise (i) a sandy, partly weathered diamicton (Craig of Boyne Till Formation, CBTF) resting on decomposed bedrock, (ii) a central, variably glaciotectonised assemblage of dark clay, diamicton and sand, with rafts of sand and weathered diamicton (Whitehills Glacigenic Formation, WGF), and (iii) an upper dark sandy diamicton (Old Hythe Till Formation, OHTF). The CBTF was probably derived from the west or southwest, and the WGF from seawards. Structures within the OHTF conform to deposition by east‐ or southeast‐moving ice from the Moray Firth, but some erratics indicate derivation from the south. The CBTF is believed to pre‐date the last (lpswichian) interglacial, but the WGF and OHTF both post‐date the early Middle Devensian, and are probably of Late Devensian age. It is proposed that the OHTF was deposited by ice from inland which was directed eastwards near the coast by a vigorous glacier in the Moray Firth, and that the complex, Late Devensian glacial history of the south coast of the Moray Firth as a whole is the result of the interplay of these two contemporary ice‐masses.

The paper compares and contrasts the development experiences of two fisheries-dependent archipelagos: the Shetland Islands, located in the temperate seas of the North-east Atlantic, and the Lau community of the island of Malaita, in the Solomon Islands of the tropical Pacific Ocean. Whilst the coastal communities of both island groups have always depended upon the sea for their livelihood, their indigenous peoples are distinct in origins, culture, historic tradition, economy, and social imperatives. However, a closer examination of the recent development of the two archipelagos reveals that, whilst they are contrasting in the fisheries sector specifics, they have, over different time scales, adopted similar management strategies in the pursuit of sustainable fishing. In both instances, the island communities have sought to support the local fisheries economy by tempering the external forces of the centre. This has been achieved, with varying degrees of success, by adopting management control and resource 'ownership' strategies in response to social and economic turbulence in the environment. The experiences of the two archipelagos have demonstrated that to maintain a coherent fisheries management strategy over time and a sustainable resources base requires a pro-active approach, the input of resources, and moderation of the pressures created by the market. The future is uncertain as the fisheries organisations of the archipelagos seek to stabilise the access and ownership arrangements applied to the common-property fisheries resources of coastal waters.  相似文献
