儿童友好型社区营造中的参与者社会网络构建与分析 —以湖南省长沙市育才第三小学"娃娃农园"营造实践为例

Introducing the case of the Kids’ Gardens in Yucai No. 3 Primary School in Changsha City, Hunan Province, this study established sociograms upon the contact-frequency-based network with UCINET to systematically analyze the characteristics of different participants in the process of the childfriendly community building and the varying pattern of all social relations, aiming at addressing problems emerging in public participation and multi-stakeholder collaboration in Chinese mainland. It was found that by bonding stakeholders including citizens, the government and party organizations, universities, and public institutions and enterprises, this practice encouraged the school — as a community — to leverage its internal resources. The school finally overcame the organizational inertia and achieved independent operation and growth during the process of community building. The study also demonstrated that the social network of participants was developed and defined with both independent and dependent modes from an overall perspective, of which the former characterized for its dominant internal ties and a dense tree-like hierarchical management structure might be more efficient. From a participant perspective, the brokerage roles in key nodes were critical to the community building. Finally, spatial design strategies, including enhancing the spatial affordance to serve diverse activities, space zoning and allocation, offering “half-done” spaces, and phased development, were provided for similar community building practice.     

PLANT’S-EYE VIEWS OF TAIPEI

The installation of “Plant’s-Eye Views of Taipei” is the result of an international workshop that took place in Taipei in summer 2018, organized as part of the 2018 Taipei Biennial. Under the direction of two participating artists, and with the help from ecologists and videographers, university students from the Asia-Pacific region each imagined themselves as a particular plant. Students began by examining the physiology of selected plants to better understand their characteristics and life histories, as well as their adaptive features and ecosystem behaviors. In viewing themselves as plants, students were able to see Taipei through a new lens as a place coproduced by the city’s urban flora and human communities. The installation including scaffolds, sketches, and films was exhibited at the Taipei Fine Arts Museum to explore different ways through which plants view the city, as well as notions of anthropomorphism, phytomorphism, and phototropism.     

The Localization of “Imported” Urban Form in Northeast China: The Case Study on Circular–Radial Space in Dalian City

After the “imported” urban forms, which originated from foreign cultures, were transplanted into Chinese cities, they generate brand-new urbanscape but suffer from a lack of cultural roots and a disconnection with the mainstream of contemporary urban planning. Thus, their current value and potential in urban renewal are questioned. The study takes the circular–radial space from the Baroque cities as an example to clarify the motivation of its import from the west to northeast China. It further clarifies their adaptive changes in form and function in the local urban context, through a case study on Dalian City. The study finds that different geometric patterns of existing circular–radial space were influenced by European, American, and Japanese urban planning theories to varying degrees, but with equal emphasis on symbolism and functionality. Their implementation in Dalian has a continuity in time and space. But due to the changes in topography, traffic, and planning concepts, their forms and functions tend to be independent, their connection weakens, and their importance recedes after the street network. The circular–radial space in Dalian led to distinctive urbanscape. But during their inheritance and transformation, the rationality of new forms and functions, as well as the necessity of continuing the initial ones need to be dialectically considered, so as to avoid dogmatic revival and antique reproduction. Finally, the study reconsiders the concept of “localization” of “imported” urban form, and constructs a general research pattern to provide a new perspective for understanding the transformation of similar types of urban forms.

提出了一种新型空间半刚性C型节点。为使该节点具有较好的转动能力及耗能能力,基于“强节点、弱构件”的抗震基本原则,提出了“强连接、弱板件”的空间半刚性节点。首先根据规范及理论分析初步确定节点各组件的合理尺寸;然后运用ABAQUS有限元软件建立非线性有限元模型,对节点各组件的尺寸进行优化,确定合理的组件尺寸。通过有限元分析和试验对该节点的性能进行研究。结果表明：该空间半刚性C型节点在弯矩荷载作用下表现出了较好的受弯承载能力和延性;节点刚度及承载力均随锥头侧连接板厚度、前端板厚度的增加而增大。节点锥头部分的材料本构模型选取对有限元分析结果的影响显著,采用三折线模型模拟所得结果更为精确。     

Fostering Urban Digital Integrated Systems: The Case of Carrè Laval,Canada

City governments are embracing digital technologies to improve hard and soft urban systems, so as to create and improve urban experiences, foster an entrepreneurial city, as well as devise novel services that can improve the livability of citizens and boost the local economy. Unlike traditional infrastructure and urban systems, which tend to be natural monopolies, data-driven digital platforms can engage multiple stakeholders simultaneously. This article, introducing the notion of hybrid urban digital integrated systems, proposes a methodology aims at the integration of digital and physical elements in urban environments. We based our discussion on the work developed by students at the Massachusetts Institute of Technology Senseable City Lab, which focused on the integration of the digital-technology-based solutions in Carré Laval of the city of Laval, Canada. As the result of the workshop, six projects have been developed by students, namely, “Activating Surface,” “Infinite memories,” “Fora,” “iTable,” “MinecARft,” and “Foodprint.”These designs aim at promoting civic engagement as intrinsic elements of the re-appropriation and redesign of this severely underutilized site. The human-centered designs rooted in specific context will help digital technologies embedded in the city and increase the attractiveness of the city to local and new stakeholders.

Rationalist Practice

Max Dudler's buildings, conceived as apparently autonomous and self-referential objects, nonetheless demonstrate a reciprocal relationship with the city and have, over the past two decades, presented a consistent Rationalist approach. Born in 1949 in Switzerland, Max Dudler studied architecture in Frankfurt/Main and Berlin. From 1981 to 1986 he worked in the office of OM Ungers on the projects for the Frankfurt trade fair, and has run his own practice, with offices in Berlin, Frankfurt and Zurich, since 1992.

The Replanting and Localizing of Chineseness in Whampoa’s Garden of Singapore

Private Chinese gardens in 19th-century Singapore were rarely designed in the same way as their contemporary counterparts in China, though there were a few authentic Chinese mansions in the city. In response to this phenomenon, this paper attempts to use Whampoa’s Garden, the finest and earliest private Chinese garden on the island, as an example, to explain how and why garden owners selectively adopted certain Chinese features while designing the rest of their gardens in a way deviating from Chinese traditions. The study of Whampoa’s Garden begins with a sketchy introduction to the career and cultural background of the garden’s owner, Cantonese businessman Hoo Ah Kay, addressing his social connections, personal hobbies, and cultural identities. As the garden no longer exists, a study of available pictorial and written records from Chinese and Western sources is conducted in order to reveal the spatial layout and other designed features of the garden, some of which may have facilitated the display of Chineseness. Contemporaneous gardens from Hoo’s hometown will be compared to unveil hidden linkages between Whampoa’s Garden and Chinese garden ideas. Furthermore, the relationship between the selection of Chinese symbols and the identities of their audience is examined as an approach to studying what affected how Chineseness was presented and how the landscape of south China was transplanted to this equatorial colony.     

Stable expression and control parameters in the numerical simulation of unsaturated flow

The Richards’ equation describes the flow phenomenon in unsaturated porous media and is essential to hydrology and environmental science. This study evaluated the numerical stability of two different forms of the Richards’ equation. Sensitivity analyses were performed to investigate the control parameters of the equation. The results show that the h-form Richards’ equation has better applicability for calculating variable saturation flows than the θ-form Richards’ equation. For the h-form Richards’ equation, the hydraulic conductivity of the soil in the low-suction range and the specific moisture capacity in the high-suction range primarily influenced the solution. In addition, sensitivity analyses indicated that the saturated hydraulic conductivity, initial condition, and air-entry pressure have a higher sensitivity to the simulation results than the saturated water content, rainfall intensity, and decline rate of hydraulic conductivity. Moreover, their correctness needs to be guaranteed first in numerical simulations. The research findings can provide a helpful reference for improving the reliability of numerical simulations of unsaturated flows.     

Screens

The screen is a recurring element in the work of Niall McLaughlin Architects . Environmental considerations have provided the opportunity for inclusion of the screen in built works, but it has been embraced by them for its geometric and material qualities, as well as the play it affords with light. The practice has relished the transformative powers of inserting everyday found objects into the screens to provide an additional level of surprise and delight.

运用空间句法衡量小型城市公园的安全性——以埃及开罗市罗德-法拉格公园为例

Decoding the relationship between crime and place has been the focus of researchers in both design and social fields for a few decades. Space syntax theory offers the possibility of examining the configuration characteristics of the environment and their potential influences on people’s activities and crime patterns; however, its implementation in landscape architecture has been limited. This study responds to such a gap by exploring the effectiveness of applying space syntax theory to predict safety levels in a park in Cairo, Egypt. depthmapX was used to analyze the spatial configuration of the park. Crime records from 2019 were collected through site observation and staff interviews, and analyzed using ArcGIS 10.3 software. Results indicated a strong correlation between space depth / integration / connectivity and crime pattern distribution. The park visibility graphs indicated the different impacts of vegetation (evergreen tree / deciduous trees) in summer and winter on visual connectivity and crime types. The research concluded that applying space syntax theory to landscape architecture is challenging; nevertheless, it represents a promising approach to predict committing crimes in urban parks, and the findings can be adopted to enhance park conceptual designs to achieve higher safety level.     

Rebranding Terroir: Ethnoecology and Tea Agro-Ecosystem Management in Response to Increased Market Integration in Southern Yunnan,China

Prompted by increased domestic and transnational demand for Pu’er tea, an emergence of agroecosystem intensification in Southern Yunnan, China has resulted in various agro-ecosystems including tea forests, mixed crop systems, and monocultural terrace tea gardens, in the tea production system. Plants of Camellia sinensis assamica often grow as trees in forests whilst C. sinensis sinensis grow as shrubs in terrace tea gardens. Inspired by the wine industry, the concept „Terroir” acts as a framework that analyzes both environmental and human factors yielding var ying botanic profiles, and hence quantifies values created by the cultivation process. The approach allows economic opportunities of place-based tea products to be driven by the origin in lieu of extrinsic qualities, which has resulted in to the fabricated reputation of terroir. In response to a common gap in terms of botanical and cultural values between tea cultivation and marketing trends, this artic le investigates an alternative scenario in which tea production and promotion model could minimize its environmental impacts and utilize its economic weight to advance land conservation efforts specific to cultural complexity at community scales.     

Differential patterns of antimicrobial resistance in population subsets of Escherichia coli isolated from waste- and surface waters

The species Escherichia coli comprises different subgroups with distinct phylogeny, physiology and ecology and, thus, presumably, with different roles in antimicrobial resistance dissemination. E. coli strains isolated from raw and treated municipal wastewater and from urban water streams were characterized in terms of phylogenetic groups, antimicrobial resistance patterns and the presence of class 1 and class 2 integrons. Our main objective was to investigate the contribution of the different phylo-groups in antimicrobial resistance dissemination in urban waters. Groups A and B1 were predominant in all types of water, evidencing, respectively, the lowest and the highest resistance prevalence. Municipal wastewater treatment was accompanied by significant increases of ciprofloxacin and streptomycin resistance (p < 0.01). Antimicrobial resistance prevalence differed significantly between the different phylo-groups and within the same group, mainly in group A. Such differences contributed to explain the higher ciprofloxacin and streptomycin resistance rates observed in treated effluent in comparison with the raw wastewater. We conclude that the dynamics of the bacterial populations has a major role on the dissemination of antimicrobial resistance in the environment.     

砂井径向排水的不均匀固结效应及简易量化方法

软土的不均匀固结问题普遍存在而且未受到足够的重视，不均匀固结会带来“淤堵”问题，影响单元体径向排水速率。文中利用数值方法研究砂井单元体的径向固结，首先通过分析单元体内部的土体孔隙比和渗透系数的径向分布特征，论证砂井径向排水的不均匀固结特性；对单元体平均固结度的数值模拟结果和理论解析结果进行比较，指出不均匀固结效应对孔压消散速率的影响，并提出可以表征不均匀固结效应影响程度的“等效涂抹效应”的概念（Ke）；最后，文章进一步研究Ke与土体的压缩性、渗透性和应力条件之间的关系。基于文中的研究结果，提出利用土体基本的物理力学指标和工程设计参数对“等效涂抹效应”（Ke）进行计算的简易量化方法。     

Residues of veterinary antibiotics in manures from feedlot livestock in eight provinces of China

The residue levels of selected fluoroquinolones, sulfonamides and tetracyclines in 143 animal dung samples collected in 2007 from large-scale livestock and poultry feedlots in 8 provinces were determined by using ultrasonic extraction and liquid chromatography. Recoveries from spiked pig dung samples (spike level = 1 mg/kg) ranged from 73.9 to 102.0% for fluoroquinolones, from 81.6 to 92.3% for sulfonamides, and from 57.2 to 72.6% for tetracyclines. Relative standard deviations of the recoveries were less than 10% within the same day. Method quantification limits were measured from 0.031 to 0.150 mg/kg for fluoroquinolones, from 0.023 to 0.082 mg/kg for sulfonamides, and 0.091 to 0.182 mg/kg for tetracyclines in spiked pig manure samples. Analysis of 61 pig, 54 chicken and 28 cow dung samples collected in China revealed that in pig and cow dung, up to 33.98 and 29.59 mg/kg ciprofloxacin, 33.26 and 46.70 mg/kg enrofloxacin, 59.06 and 59.59 mg/kg oxytetracycline, and 21.06 and 27.59 mg/kg chlortetracycline could be detected, respectively. A maximum concentration of 99.43 mg/kg fleroxacin, 225.45 mg/kg norfloxacin, 45.59 mg/kg ciprofloxacin and 1420.76 mg/kg enrofloxacin could be detected in chicken dung. No appreciable sulfonamide antibiotic concentrations (less than 10 mg/kg) were found in any animal dung, and only sulfadimidine was observed, at a maximum concentration of 6.04 mg/kg, in chicken dung. Both enrofloxacin and chlortetracycline were detected with a very high occurrence in three animal manure samples. The residue levels for most antibiotics showed significant statistical differences among the sampling districts and the animal species.     

Skin/Weave/Pattern

‘Fabric is the perfect mediator between the firm and the flowing.’ Nigel Coates celebrates the textile's rediscovery as a metaphor for the architectural envelope, liberating it from its reputation as having only a supporting, ‘comfort role’ in the interior. He describes his own experiments with textiles at Branson Coates Architecture and the Royal College of Art (RCA), in which they alternately become skin, weave and pattern operating at every scale from the individual body to the urban plan.
