The City of Richgate: A/r/tographic Cartography as Public Pedagogy

The City of Richgate project worked with eight intergenerational immigrant families and examined immigrant experiences and narratives through a community‐engaged process that employed a/r/tography as a methodology. As such, the research also investigated the extent to which a/r/tographical research could visually and narratively portray the analysis of data collected by the co‐a/r/tographers. After interviewing and collecting images from each family, large artistic gates (banners) were created. This first phase of the project revealed the power of images in situ, and thus the power of a/r/tography in situ. For the community members and co‐a/r/tographers meanings were constructed within ongoing a/r/tographic inquiries described as collective artistic and educational praxis. The second phase involved the identification of important places by each family within the City of Richmond. After analysing all of the data, several works of art were created with each family in mind: bus shelter images juxtaposing close‐up and far away geographical images; side‐by‐side images portraying historical and contemporary images of family ideals and/or issues; banners illustrating families in meaningful poses; and archival collections portraying the importance of identity and memory in the transformation of culture. This phase culminated in a citywide exhibition of the artwork performing public pedagogy. The exhibition questioned the idea of a City of Richmond having a community centre, and instead exhibited many Richgates, or conceptions of Richmond. Rather than having a city centre, there are many centres, a Network of Cities of Richgates, where centres are constantly changing and shifting to reflect the narratives of individuals living in a psycho‐geographical region of a city.     

基于积极心理学的艺术心理治疗述评

积极心理学是西方心理学界兴起的一个新的研究领域,现在受到越来越多研究者的关注.本文在对积极心理学的概念及与心理治疗相关的积极心理学研究内容进行简单介绍的基础上,进一步引入积极心理治疗和艺术心理治疗的概念.进而把积极心理学与艺术心理治疗相结合提出基于积极心理学的艺术心理治疗理念,并对其主要分支--文学艺术治疗进行简单评析.基于积极心理学的艺术心理治疗的理论观点和实践模式还有待临床的进一步检验和开发.

Web服务组合规范WS-CDL的类型化形式化模型

为了形式化地推理和验证web服务编排规范WS-CDL所描述的web服务组合,提出了一个WS-CDL规范的类型化形式化模型——typed abstract WS-CDL.在typed abstract WS-CDL中,定义了类型和会话的语法、类型判定规则和操作语义;web服务间的协作由会话来描述;利用会话的操作语义能对web服务编排的执行进行推理;利用类型判定规则能检查web服务间交换信息类型一致性并捕获由于类型不一致导致的运行时错误.特别地提出了类型假设集的外延和类型假设集相容性的概念,并定义了类型假设集的合并算法以消除类型假设冲突.在该模型基础上,还定义了从choreography到orchestration的类型化映射规则,通过这组规则,可以从一个给定的web服务choreography得到orchestration桩代码及其类型假设集,因而web服务组合能在choreography和orchestration层被验证.提出的模型被证明具有类型安全性,并且通过一个案例分析说明了所提出的模型是有助于对web服务组合进行推理和验证的.

Polychlorinated dibenzo-p-dioxins and dibenzofurans in flue gas emissions from municipal solid waste incinerators in China

Polychlorinated dibenzo-p-dioxins and furans （PCDD/Fs） emissions in flue gas from two types of municipal solid waste incinerators （MSWIs） most commonly used in China were investigated in this study. The selected incinerators include two grate-type MSWIs： MSWI-A （350 t/d） and MSWI-B 050 t/d）, and two fluidized bed MSWIs： MSWI-C （400 t/d） and MSWI-D （400 t/d）, which are all equipped with semi-dry lime scrubber and bag filter except MSWI-D equipped with cyclone and wet scrubber （WS） as air pollutant control device （APCD）. Results indicated that the emission concentration and the international toxic equivalents （I-TEQs） of the PCDD/Fs from the stacks were in the range of 1.210-10.273 ng/Nm^3 and 0.019-0.201 ng I-TEQ/Nm^3, respectively. They were greatly lower than the emission regulation standard of PCDD/Fs in China （1.0 ng I-TEQ/Nm^3）. However, only the PCDD/Fs emission level from MSWI-C was below 0.1 ng I-TEQ/Nm^3. Although the homologue profiles were distinct, the contributions of the 2,3,7,8-subsituted congeners to the total I-TEQ were similar among all the investigated MSWIs. Two major 2,3,7,8-substituted congeners, 2,3,4,7,8-PeCDF and 1,2,3,7,8-PeCDD, account for 47% and 9% （average values） of the total I-TEQ values, respectively. The correlation between PCDD/Fs levels and composition of flue gas was also discussed.
