乡村社区旅游生计代际传承的过程及影响因素——以栾川县重渡村为例

在乡村振兴背景下,旅游生计成为乡村可持续发展的重要议题,但与之相关的研究较为匮乏。文章以栾川县重渡村为案例地,通过对亲代和子代进行半结构化访谈,探讨旅游生计代际传承的过程及其主要影响因素。研究发现：(1)旅游生计的代际传承经历了亲代生计开拓、子代培养和发展、共同经营、生计传承四个阶段,并与重渡村这一乡村旅游目的地起步、培育、快速发展、规范管理的生命周期相适应。(2)文化因素、主体因素和规制压力是影响生计传承的主要原因。(3)旅游生计的代际传承关乎乡村旅游的可持续发展和乡村振兴战略的有效实施,相关问题值得进一步探索和研究。     

胡人发型:中古“剪头胡雏”艺术形象试解

古人发型是文化界长期关注的一个重要现象。发型不仅是时代的特征与时尚的符号,也是各个族群的辨识标志。从北朝到隋唐的中古社会,"剪头胡雏"的文物图像屡屡出现,一般来说,此类胡人形象是剪发而不是束发,在当时以"高髻为尚"的社会习俗中,"剪头胡雏"发型是有着"阶级感"的存在,是有关底层胡人的直观艺术产物。也说明当时入华胡人还没有彻底"汉化",仍然保留着本族群的发型特征。该发式是胡人与汉人的区别,也是其身份归属的象征。     

Limits to climate action - Narratives of bioenergy with carbon capture and storage

In recent years, bio-energy with carbon capture and storage (BECCS) has been awarded a key role in climate mitigation scenarios explored by integrated assessment models and referenced in reports by the Intergovernmental Panel on Climate Change. Because a majority of scenarios limiting global warming to 2 °C or 1,5 °C include vast deployment of BECCS, a critical discussion has emerged among experts about the moral implications of thus introducing an unproven technology into the policy realm.In this paper, we analyse this discussion as it has played out between 2013 and 2019, with a focus on how expert narratives are constructed in the mass media about the possibilities for decarbonisation within the current political-economic order. We find there are almost no narratives that support massive deployment of BECCS, and that all narratives presuppose limits to decarbonisation imposed by the current political-economic system. The perception of such limits lead some to argue, through deterministic and apolitical narratives, for the necessity of negative emissions technologies, while others argue instead that “degrowth” is the only solution. Thus, there is a distinct lack of positive narratives about how capitalism can bring about decarbonisation.     

污染大气中浑仪,简仪的带锈防护

浑仪、简仪（以下简称两仪）在高PH、大气污染和日晒雨淋环境中的腐蚀是一种动态加速腐蚀过程。采用合成的双唑胺铜缓蚀剂和有机硅改性的甲基丙烯酸树脂,并分别复配成协同缓蚀剂群和含有增效稳定剂的封护剂。采用这两种材料和脱水后再防护的工艺,使带锈防护后的浑仪、简仪的腐蚀低于无污染大气中的速率。用电化学方法评价了防护技术的可行性,根据腐蚀与人工老化试验结果讨论了防护材料性能与腐蚀环境和带锈防护的关系,采用XPS分析方法探索了双唑胺比BTA更适用于两仪防护的原因。     

南宁市房地产价格分布规律的机助制图研究与开发方向的探讨

南宁市房地产业经历了由沉寂、复苏、火爆到稳步发展的过程．各公司开发的房屋类型相近,但价格差异却很大,价格分布呈现明显的规律性：一是城市中心价格高,边缘与郊区价格低;二是东部城区价格高,西部城区价格低．主导价格分布规律的三大影响因子是地理位置、交通便捷程度和生态环境质量．南宁今后的房地产开发和城市规划建设一要顺应价格分布规律,优地优用、保障房地产开发的高效益;二要加强交通设施建设和环境保护．促进全市房地产的升值;三要因势利导,发展城市副中心,逐步形成多中心的城市建设格局。     

Caddoan Area archaeology since 1990

This paper summarizes recent archaeological research efforts, and changing perspectives, about the native history of the Caddo peoples who lived in the Caddoan Archaeological Area, which centers on the Great Bend of the Red River in Oklahoma, Texas, Arkansas, and Louisiana. Of particular focus are the origins and early developments of the Caddoan tradition, regional diversity, subsistence changes and agricultural intensification, sociopolitical dynamics, and Caddoan-European interaction.     

Linking polycentricity concepts to periphery: implications for an integrative Austrian strategic spatial planning practice

This contribution searches for a regional planning conception that allows for a mutual recognition and practical translation between strategies for urban regions and peripheries beyond separate urban and rural categories; taking the Austrian strategic spatial planning context as the example. For this, various notions of polycentricity are discussed and assessed with regard to periphery. The Austrian strategic spatial development concept ÖREK sets out a focused work programme with changing responsibilities and participation of actors. The objectives are targeted and the processes are implementation oriented. Amongst other topics, urban regional issues and peripheral, declining regions are worked on separately. A conceptually integrative, plan-like strategic instrument across the topics and for the whole of Austria is lacking. The ESPON notion of ‘inner peripheries’ is proposed as a complementary concept to the ESDP notion of polycentricity, helping to create a bridge between urban regional and periphery strategies. This has the potential to guide strategic planning practice efforts in Austria towards a yet missing strategic spatial plan for the whole of the country beyond urban and rural categories. Practice relevant conclusions related to the case of Austrian strategic spatial planning are drawn and a need for further, comparative research in a European context is identified.     

Informal institutional change in De Achterhoek region: from citizen initiatives to participatory governance

As in other European countries, the formal planning task of Dutch governments is subjected to devolution and austerity measures. Not only did these developments lead to outsourcing planning tasks to lower-level governments, also citizens are increasingly ‘invited’ to take responsibility for providing public facilities and services. In De Achterhoek, a Dutch region, these shifts are amplified due to population change and traditional active citizenship, and led to institutional change. Since a decade local governments stimulate citizen initiatives, under the umbrella of participatory governance. This process of institutional change did not alter formal institutions, but was the result of an informal and dialectic process between local governments and citizen organizations. In this paper, we will demonstrate the process of change and how it affected planning practices in De Achterhoek, building on theories of informal institutional change and its driving forces. The empirical part of this paper draws on the results of three focus group meetings, in which a diverse set of local stakeholders discussed the effects of change they observed and how it shaped planning practices. In the final section, we reflect on the degree of institutionalization, by examining the robustness and resilience of the observed change.     

Social sustainability tool for assessing land use planning processes

The aim of this paper was to develop a social sustainability tool to clarify what social sustainability means in land use planning processes. The tool was developed through a robust research process covering a large amount of scientific literature and built environment sustainability assessment tools. To assess how the developed tool works in practice, we used it as a coding system for the assessment of social sustainability in a case study from Finland. The case study includes the master planning process of a medium-sized city and the legal framework guiding it. The theoretical contribution of the paper lies in creating a holistic tool for the assessment of social sustainability in planning processes. This study also provides a strong practical contribution, as it goes beyond theoretical definitions to the pragmatic level by providing exemplary measures to be used in designing and implementing processes. Therefore, this paper is a valuable source for those stakeholders (for example planners, developers and policymakers), who struggle with the issue of the successful implementation of social sustainability practices, and it will help them to benchmark their processes against the themes found in the tool.
