摘要： The processes related to solid waste management (SWM) are being revised as new technologies emerge and are applied in the area to achieve greater environmental, social and economic sustainability for society. To achieve our goal, two robust review protocols (Population, Intervention, Comparison, Outcome, and Context (PICOC) and Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA)) were used to systematically analyze 62 documents extracted from the Web of Science database to identify the main techniques and tools for Knowledge Discovery in Databases (KDD) and Data Mining (DM) as applied to SWM and explore the technological potential to optimize the stages of collecting and transporting waste. Moreover, it was possible to analyze the main challenges and opportunities of KDD and DM for SWM. The results show that the most used tools for SWM are MATLAB (29.7%) and GIS (13.5%), whereas the most used techniques are Artificial Neural Networks (35.8%), Linear Regression (16.0%) and Support Vector Machine (12.3%). In addition, 15.3% of the studies were conducted with data from China, 11.1% from India and 9.7% of the studies analyzed and compared data from several other countries. Furthermore, the research showed that the main challenges in the field of study are related to the collection and treatment of data, whereas the opportunities appear to be linked mainly to the impact on the pillars of sustainable development. Thus, this study portrays important issues associated with the use of KDD and DM for optimal SWM and has the potential to assist and direct researchers and field professionals in future studies.

摘要： Purpose This paper aims to develop a framework that could establish and further the terminology of smart city/resilient city discourse in that resilience could support urban "smartness", a term that is widely argued being not easily measured nor quantifiably assessed. Design/methodology/approach The qualitative approach was employed, and based on selected keywords, a systematic literature review was carried out to understand the main themes within the smart city and resilient city concepts databases. Upon screening, 86 papers were used and synthesised through the meta-synthesis method using both synthesis approach, meta-aggregation and meta-ethnography that systematically identifies both properties and characteristics, to build an innovative framework as an indicator-based smart/resilience quantification model. Findings Two novel frameworks are proposed, smart resilient city (SRC) and resilient smart city (RSC), as guidelines regulatory that establish a city's smartness and resilience. Research limitations/implications The quantitative research phase is not provided as the framework builds on the exploratory approach in which the model is proposed through the postulation of data definitions. Practical implications Although the study's scope was limited to the city, proposed frameworks may be interpreted for other contexts that deal with the topic of resilience and smart. Originality/value The established framework proposal would encourage further exploration in context, serving as an inspiration for other scholars, decision-makers, as well as municipalities to keep strengthening smart city through resilience factors.

关键词： 当代文学   上海叙事   《长恨歌》   《繁花》  

摘要： 自开埠以来,上海便一直走在中国城市发展的最前沿,得天独厚的地理位置和频繁的商业活动促使上海形成了中西交融的城市性格和文化精神。文学是现实生活的反映,关于上海的城市叙事在中国现当代文学史上占有重要地位,且形成了独特的海派文风。随着历史的发展,上海叙事在当代文学中又呈现出新的面貌。王安忆的《长恨歌》与金宇澄的《繁花》作为当代上海城市书写的代表作品,在重建城市空间、描绘市民生活、捕捉上海的精神意蕴等方面都有着出色的表现。同时,两者也对当代上海在迅速发展过程中出现的世俗生活的瓦解与消亡、市民信仰的缺失与混乱、现代人的生存困境等问题进行了反思和批判,值得人们深思。

关键词： 城市精神   文学精神   审美   阶级   观念剩余物  

摘要： 自出现以来,城市在空间层面上承担物质生产的同时,也隐藏着时间观念上的精神史的生产,这就与同样聚焦精神领域的文学产生了同论的可能。不过,城市精神与文学精神并不总是同构的发展,而是存在于多种话语的复杂交织之中。城市源于现代性的发展,但现代美学并未给予城市审美的向度。历史与审美的分裂常常是巨大的,这使得文学精神具有相对独立性。1930年代以来,阶级话语逐渐成为决定城乡关系的重要维度,但这并不意味着历史与审美话语的失效。城市精神经历了从被命名到被改造的过程。城市起初因为“剩余”而出现,但这种“剩余”不仅是物质上的,也有观念上的。很大程度上,文学表达的就是这种作为观念剩余物的城市精神。

关键词： 都市文化生活   南京文学   互动关系   都市转型  

摘要： 作为一座兼具传统性与现代性的城市,南京在都市文化生活和地域都市文学两个方面都有内容丰富、形式多样的成熟体系。2019年"文学之都"称号的授予,更是对南京都市建设的一种重要认可。近年来,以都市文化、文学为对象的各种研究层出不穷,南京还有一些空白领域需要填补;同时随着都市化进程的深入发展,如何利用好都市文化生活与文学的各种资源,对于南京未来的城市转型也具有战略意义。在这一大背景下,本文尝试以都市文化生活与文学南京的互动关系为切入点,通过分析两者的内涵构成准确把握这种互动的影响路径和整体特征,进而在新的观察视角下为南京的都市转型提供一点浅薄的意见。

摘要： 唐宋文人的城市文学书写敏感的捕捉街这个空间意象展开对城市的诗意想象。随着城市转型进程中坊市制和宵禁制度的逐步崩坏,街这个线性公共空间从政治性的奔竞之途向城市生活舞台转化,从“六街鼓绝尘埃息”的宵禁冷落走向“金吾不禁六街游”喧闹,从农耕自然审美逐渐融合街市欲望审美,这种变动刻镂出城市转型在街这个独特空间留下的痕迹。

摘要： 现代社会,城市与人类的关系日益紧密和复杂。城市特征体现在经济、政治、科技、文化和日常生活等各种领域,城市空间不仅提供了生存场域、自然和人文景观、文化载体,还负责保存人类的历史记忆和生存想象。城市具有历史性、当下性和未来性,文化本身是一种媒介,作为公共领域与现代集群,后现代城市生态系统中的自然空间、文化空间、心理空间和情感空间,不断嬗变而呈现为过度的消费性。全球化浪潮中,城市的个性逐渐弱化,世界性流动和文化互动功能强化了虚假的共同体景象。就人与城市的关系而言,包含着认同和疏离,城市文化空间既是被建构的客体,更是对人有着潜移默化塑造力量的主体。审视当代文学中的城市叙事,日常生活于自发的经验性空间复制生成,消解了向理性敞开的反思领域,物化的现实充满诱惑和喧嚣,而个体的人,无论是单向度地被裹挟,还是自视清醒,其认知和经验都是有局限的。小说家提供生存差异、命运拆解、情感边界和世界裂痕,展现的是当下情境中的复杂日常,城市叙事终究落点在市民生活,运用自然主义白描,寓言或者隐喻符号,无非是形式。后人类社会,虚拟空间带来了新的交往体验,如果把真实世界看成是巨大的他者,人类无疑正经历最深刻的隔阂与封闭;反之,互联网平台提供的看与被看,则进一步强化了现代生活的橱窗效应。

摘要： 狄更斯在《匹克威克外传》中使用伦敦腔来塑造城市下层人物形象,迎合了19世纪前期英国读者的阅读需求。他选择社会中下层人士作为主要读者群,利用伦敦都市情怀和帝国情结为他们编制了一个温婉的美学幻象。《匹克威克外传》每期均制成文学册页售卖,以连载形式激发读者的好奇心与获得感,迅速打入文学快速消费品市场,唤醒和刺激了中下层民众潜藏已久的文学消费欲望,推动了英国文学市场的大繁荣。

关键词： Urban rainfall-runoff pollution   Control technologies   Bibliometric analysis   Research hotspots   Literature summary   Development tendency  

摘要： Rapid urbanization in China is driving the need of urban rainfall-runoff pollution control technologies due to adverse impacts on water environment. In this study, literature from China National Knowledge Infrastructure, Web of Science and Scopus in 1995/1/1-2019/5/15 are used to review research hotspots, development process and future directions of urban rainfall-runoff pollution control technologies in China and global world. Temporal evolution of publications showed that source reduction played better growing trend in urban rainfall-runoff pollution control field for both China and global world. Furthermore, with bibliometric tool, density visualization maps and co-occurrence network maps were created to identify research hotspots in China and global world. By comprehensively analyzing research hotspots above and development process from extracted literature, future directions of urban rainfall-runoff pollution control technologies were predicted. For model and strategy, both China and global world would concern on the accuracy of models to evaluate combination technologies. For source reduction, China would explore rainwater purification in sponge city, while global world would investigate match characteristics between specific regions and control technologies, combination between model and technologies, and improvement of pollutants removal. For process control, China would enhance ecological gutter inlet performance, whereas global world would concentrate on optimization of rainwater harvesting system. For post treatment, China would estimate modified hydrocylone and coagulation technology, and improve

关键词： 吴君   深圳   “文学深圳”   小人物   城市文学  

摘要： 吴君扎入“底层现实主义”立场、思想持续不断地讲述着形形色色的“深圳故事”,成为当代文坛最具风格和倾向性的小说家之一。她从都市空间切入,不仅将都市中具体的地理坐标或方位纳入考察、审视的对象,更将此空间中的人、事、物及其关系作为素材收集、灵感生发和文学建构的基本依托,实际上也就将人与现代都市(深圳)最内在、最深层的纠葛以及由此而生成的隐秘景观传达了出来。作为当代城市文学的又一新坐标,吴君的“文学深圳”专为小人物而造,是“独特的这一个”,其文学地理学意义不可低估。同时,作为当代城市文学代表作家之一,吴君的文学实践与文学史亦存在渊源相继的关系,故吴君及其小说都值得予以全面、深入研究。
