This study employs the Institutional Analysis and Development framework across three collaborative watershed partnerships with differing membership profiles (government centered, citizen centered, or mixed) to determine how rules at varying levels of action (operational rules, collective-choice rules, and constitutional rules) affect the formation and implementation of rules-in-use at different levels. Examining trends across group types at varying levels of action helps illuminate how the operational rules produced by different types of partnerships result in outputs that impact watershed management. Results show that the source of rules and their impact on subsequent levels of action vary by group type, with federal and state policies playing a larger role in government-centered and mixed-membership groups than in citizen-centered groups.  相似文献

"东亚"既是一个空间性概念——即地理性、地域性的概念,又是一个时间性的概念——即历史性的和意识形态的概念。现代性的介入,使得"东亚"成为一个需要不断重新界定和检验的概念。区域东亚是知识"东亚"的理解和阐释对象,知识"东亚"是区域东亚在理论和知识上的抽象和提升。区域东亚在结构上具有封闭性、多元性的特征,在功能上又具有流变性和开放性的特征。知识"东亚"的命题集中反映了知识界的"中心-边缘"结构、各种知识背后的意识形态竞争和权力诉求。现代性和东亚的关系并不是一种单向度的"冲击-回应"关系,而是一种双向的相互建构的共生关系。  相似文献

略论金代山西文人与地域文学的发展及原因   总被引:2,自引:0,他引:2  
金代山西地域文学的发展历程可分为三个阶段:一是从金太祖到海陵王迁都之前(1115-1153),是金代山西地域文学的复苏期。二是海陵王迁都之后到章宗朝(1153-1209),是金代山西文学的发展期。三是从卫绍王到金亡(1209-1234),是金代山西文学的繁荣期。金代山西地域文学在金末迎来鼎盛局面主要有三方面的因素:一是中原文化重心的北移;二是"壬辰北渡"时期山西士人的回归;三是金末山西文人的忠国意识与使命感。  相似文献

前人对东魏北齐时期邯郸县设治问题的研究存在两种截然相反的观点——"撤治说"和"设治说"。河北省磁县出土的《窦奉高墓志》记载窦氏在北齐时期被授予"邯郸县伯"的爵位,为"设治说"提供了有力证据。  相似文献

Abstract: Subsequent to the Brundtland Report (World Commission on Environment and Development 1987, Our Common Future), sustainability has been set up in many countries as a mission statement of cross‐sectoral policies. Sustainable development carries the normative notions of equity, empowerment and environmentally sensitive economic development. Thus, it seems to suggest a fundamentally different vision to neoliberal dogma, which is at the same time described as dominating all socio‐political processes. This paper intends to explore the relation between these two discursive framings of contemporary policies through the example of German spatial planning guidelines. More precisely, it addresses social justice as one pillar of sustainability and how it is operationalised in spatial planning policies in Germany. This may exemplify how the seemingly opposing discourses interact in policy practices. The empirical analysis suggests that the ways in which the German spatial planning report focused on social space in territorial terms promotes an economistic and truncated view of social justice, one which fosters the neoliberal idea of regional competition for global capital and reduces socio‐spatial justice to territorially equally distributed economic inclusion.  相似文献

X-ray fluorescence analysis of obsidian artifacts from sites located in Chaco Canyon and from three Chaco-era communities in New Mexico permits determination of their geological origin. These source data are used to describe patterning in obsidian procurement in sites located in Chaco Canyon dating from A.D. 500–1150, and in a three non-Canyon communities occupied during the period of Chaco Canyon's regional prominence (ca. A.D. 875–1150). These data demonstrate that the most proximate sources generally dominate the sourced obsidian assemblages from sites of all periods, but also suggest differences in procurement patterning both over time and across space. Within Chaco Canyon, there is a notable shift from Mount Taylor obsidian to use of Jemez Mountains sources over time. These data also suggest that earlier analyses of obsidian from sites in Chaco Canyon misidentified some obsidian artifact sources; these new data indicate the central areas of disagreement and provide a revision of procurement patterning. In the Chaco-era communities located outside Chaco Canyon, procurement patterning diverges. The Blue J community shows an increase in use of the nearby Mount Taylor source over time. Two communities located toward the southern extent of the Chaco great house distribution reveal a markedly distinct procurement pattern, obtaining nearly all of their obsidian from southern sources largely unrepresented at Chaco Canyon. Combined, these data provide new insights into raw material procurement and artifact production at sites in Chaco Canyon, and in communities occupied during the Chaco Phenomenon, the period of the Canyon's greatest regional influence.  相似文献

Field trips have long been central to geography, but have been subject to assessment of the role of the ‘field’ in teaching. At the same time, academics face barriers to running field trips. Distance education and enhanced educational access for non-metropolitan students represented such an obstacle at an Australian university. These obstacles were taken as an opportunity to draw on the regional nature of the students and staff to enhance teaching goals, run critically informed field trips by and manage academic workloads. We evaluate the field trips by conducting surveys and interviews with students and tutors, and as an example of innovation within constraints.  相似文献

The elemental fluxes and heat flow associated with large aquifer systems can be significant both at local and at regional scales. In fact, large amounts of heat transported by regional groundwater flow can affect the subsurface thermal regime, and the amount of matter discharged towards the surface by large spring systems can be significant relative to the elemental fluxes of surface waters. The Narni‐Amelia regional aquifer system (Central Italy) discharges more than 13 m3 sec?1 of groundwater characterised by a slight thermal anomaly, high salinity and high pCO2. During circulation in the regional aquifer, groundwater reacts with the host rocks (dolostones, limestones and evaporites) and mixes with deep CO2‐rich fluids of mantle origin. These processes transfer large amounts of dissolved substances, in particular carbon dioxide, and a considerable amount of heat towards the surface. Because practically all the water circulating in the Narni‐Amelia system is discharged by few large springs (Stifone‐Montoro), the mass and energy balance of these springs can give a good estimation of the mass and heat transported from the entire system towards the surface. By means of a detailed mass and balance of the aquifer and considering the soil CO2 fluxes measured from the main gas emission of the region, we computed a total CO2 discharge of about 7.8 × 109 mol a?1 for the whole Narni‐Amelia system. Finally, considering the enthalpy difference between infiltrating water and water discharged by the springs, we computed an advective heat transfer related to groundwater flow of 410 ± 50 MW.  相似文献

以西安市长安区、渭南市澄城县、宝鸡市岐山县为考察点,采用问卷调查法和SPSS软件对三县土地流转现状进行实证分析,以查明不同区域土地流转差异情况和造成土地流转差异的影响因素。结果表明,由于经济发展水平不同,三县区土地流转达成比例相差较大,流转规模、流转方式有很大不同,流转价格更是有较大差别,经济发达地区有较强的土地"非粮化"现象,土地流转更接近市场行为。非农收入水平、农户的受教育程度、各类土地流转中介和管理机构的完善程度、农户的社会保障程度等对土地流转有显著影响,且影响方式均为正向,并且对流出率的影响超过对流入率的影响。  相似文献

清季财政改制是中国近代制度转型的重要一环,其运作过程涉及清季政治派分、区域财政利益、趋新与守旧观念等多重因子,折射出制度变迁并非单纯遵循所谓的近代化趋向。研治此段历史,应抱具"整体历史"意识,打破学科藩篱,关注人与制度之间彼此牵制的纷繁乱象,抛开今人习见观念,深入时境,作纵深切入,当日制度变迁中的不新不旧、童牛角马之实态方可得以展示,各类嬗变面相亦可近真呈现。  相似文献
