民族互嵌社区精准治理的理论向度与实践路径——以贵州省兴义市S街道社区为例

民族互嵌社区是中华民族多元一体格局空间场域延展的实践形态,是对“各民族相互嵌入式的社会结构和社区环境”这一时代命题的现实阐释。现代城市社区功能的集聚和细化为民族互嵌的再造及重释提供了场域空间,由于民族互嵌社区具有公共性、聚合性和互动性的本质特征,从而形成了立体化嵌套结构,催生出精准互嵌理论和实践的“双重愿景”:理论层面,要深刻把握民族互嵌社区精准治理的目标向度、方法向度、内容向度;实践层面,要精准识别民族互嵌社区的场域情境,以智能技术描绘民族互嵌过程的“全景图”和“晴雨表”,通过社区制度体系的精准供给,提升民族互嵌社区精准治理的效能。     

国家权力与城市空间:当代中国城市基层社会治理变革

确立和调整城市治理的空间策略是现代国家的重要任务。改革前中国的单位体制,使国家能够依靠单位实现“单元分隔”式的治理模式。改革以来,这种整齐划一的空间战略无法适应新的城市社会变迁。在城市社区管理体制改革中,出现了三种不同的国家空间战略,即“政党国家”,“行政国家”和“社会化国家”模式。当前城市社区改革的困难和复杂性体现了以上三种空间战略的对立和冲突。     

从杜夫海纳的困境中突围——《审美经验现象学》中的文学作品理论

作为现象学美学经典文本的《审美经验现象学》对审美活动进行了深入的剖析,但令人遗憾的是,杜夫海纳在该书中却回避了对同为艺术作品的文学作品的分析,这种回避源自杜夫海纳对于语言优先性的坚持。如果从语言的陈述性入手,或许可以为文学理论的构建提供一个新的思路。     

创新活动的思维机制

创新思维是具有实践性、整合性和开创性的思维 ,创新的思维发生主要表现在 :发现导致创新的问题 ,想象可能创新的空间 ,洞察推出创新的机遇 ,反馈动态创新的信息。创新思维是在不确定、不完全信息、博弈行为中展开的。创新思维要开发隐含知识和利用软件系统     

General C. L. Chennault

Because of recent legislation, many students with mild disabilities enroll in high school social studies courses in general education rather than special education settings. Therefore, teachers may have students with learning disabilities, behavioral disorders, communication disorders, and attention deficit/hyperactivity disorder in their history, geography, economics, and political science courses. Typical characteristics of these students include lowlevel reading and writing skills, processing problems, memory disorders, language problems, organizational deficits, and behavioral problems. These characteristics present challenges for the students and social studies teachers; however, there are strategies that will help the students succeed. The author summarizes the disability categories and related characteristics and describes textbook, writing, memory, organizational, and instructional modifications to address the challenges.     

网络空间与公共领域实践

以哈贝马斯的"公共领域"为理论基础,从网络空间的特质出发分析了网络空间成为公共领域的潜质,并进一步指出由于进入网络空间受经济、知识等门槛限制,以及网络空间语言霸权、数字鸿沟等面向所造成的不平等,仍制约着网络空间成为公共领域的可能。     

技术教育背景下的《大学语文》课程透析

《大学语文》作为一门素质教育课程,其重要性已愈来愈显见,但它的重要性到底表现在哪些方面,这却是要加以细致地分析的。《大学语文》在启迪学生的生存智性、拓展学生的认知时空和提高学生的美学素质等方面都有着重要的作用。     

论英语语言使用中的时空美学意义

时间概念和空间概念,与语言的使用有着千丝万缕的联系。就英语语言而论,它在表达、反映现实的过程中,会利用时空上的概念,与现实拉开距离,使人产生种种联想和思维跨越,从而实现相应的美学意义。语言在实现表达功能的同时,传达着重要的美学信息。     

Vulnerabilities and risks in population and environment studies

In the study of risks , different sciences use the same category in different ways, each related to its own ontological assumptions. But many of these fields communicate very little with one another. This article seeks to approximate two of these areas of study that have shown similar concerns and that can mutually strengthen one another, namely, geography and demography. Geography was one of the first disciplines to include risk in its environmental dimension and has had broad experience in simultaneously focusing on social and natural dynamics. Demography, on the other hand, faces greater difficulties because only recently has it incorporated the environmental dimension into its scientific scope. Both have brought the concept of vulnerability into their conceptual framework as complementary to that of risk. Geographers understand vulnerability as a more symbiotic form of the relationship between society and nature, whereas demographers give it a strong socioeconomic component. In this regard, the conceptual discussion on risks and vulnerabilities, in its attempt at approximating these two fields, is a way of conceptually advancing and strengthening the different approaches to empirical work, especially in population–environment studies which is the common ground for the dialogue between the two disciplines.

A shelf-space optimization model when demand is stochastic and space-elastic

The more customer demand is impulse-driven, the more it is space-dependent and the more it is subject to variation. We investigate the corresponding problem of retail shelf-space planning when demand is stochastic and sensitive to the number and position of facings. We develop a model to maximize a retailer׳s profit by selecting the number of facings and their shelf position under the assumption of limited space. The model is particularly applicable to promotional or temporary products.We develop the first optimization model and solution approach that takes stochastic demand into account, since the current literature applies deterministic models for shelf-space planning. By the means of an innovative modeling approach for the case with space- and positioning effects and the conversion of our problem into a mixed-integer problem, we obtain optimal results within very short run times for large-scale instances relevant in practice. Furthermore, we develop a solution approach to account for cross-space elasticity, and solve it using an own heuristic, which efficiently yields near-optimal results. We demonstrate that correctly considering space elasticity and demand variation is essential. The corresponding impacts on profits and solution structures become even more significant when space elasticity and stochastic demand interact, resulting in up to 5% higher profits and up to 80% differences in solution structures, if both effects are correctly accounted for. We develop an efficient modeling approach, compare the model results with approaches applied in practice and derive rules-of-thumb for planners.
