Abstract This paper explores the perception and politics of air pollution in Shanghai. We present a qualitative case study based on a literature review of relevant policies and research on civil society and air pollution, in dialogue with air quality indexes and field research data. We engage with the concept of China's authoritarian environmentalism and the political context of ecological civilization. We find that discussions about air pollution are often placed in a frame that is both locally temporal (environment) and internationally developmentalist (economy). We raise questions from an example of three applications with different presentations of air quality index measures for the same time and place. This example and frame highlight the central role and connection between technology, data and evidence, and pollution visibility in the case of the perception of air pollution. Our findings then point to two gaps in authoritarian environmentalism research, revealing a need to better understand (1) the role of technology within this governance context, and (2) the tensions created from this non-participatory approach with ecological civilization, which calls for civil society participation.

Vulnerability Maps

Vulnerability maps are useful for groundwater protection, water resources development, and land use management. The literature contains various approaches for intrinsic vulnerability assessment, and they mainly depend on hydrogeological settings and anthropogenic impacts. Most methods assign certain ratings and weights to each contributing factor to groundwater vulnerability. Fuzzy logic (FL) is an alternative artificial intelligence tool for overlay analysis, where spatial properties are fuzzified. Unlike the specific rating used in the weighted overlay-based vulnerability mapping methods, FL allows more flexibility through assigning a degree of contribution without specific boundaries for various classes. This study compares the results of DRASTIC vulnerability approach with the FL approach, applying both on Qatar aquifers. The comparison was checked and validated against a numerical model developed for the same study area, and the actual anthropogenic contamination load. Results show some similarities and differences between both approaches. While the coastal areas fall in the same category of high vulnerability in both cases, the FL approach shows greater variability than the DRASTIC approach and better matches with model results and contamination load. FL is probably better suited for vulnerability assessment than the weighted overlay methods.

A New Technique

Software birthmark is a unique quality of software to detect software theft. Comparing birthmarks of software can tell us whether a program or software is a copy of another. Software theft and piracy are rapidly increasing problems of copying, stealing, and misusing the software without proper permission, as mentioned in the desired license agreement. The estimation of birthmark can play a key role in understanding the effectiveness of a birthmark. In this paper, a new technique is presented to evaluate and estimate software birthmark based on the two most sought-after properties of birthmarks, that is, credibility and resilience. For this purpose, the concept of soft computing such as probabilistic and fuzzy computing has been taken into account and fuzzy logic is used to estimate properties of birthmark. The proposed fuzzy rule based technique is validated through a case study and the results show that the technique is successful in assessing the specified properties of the birthmark, its resilience and credibility. This, in turn, shows how much effort will be required to detect the originality of the software based on its birthmark.

Supporting Tool

Program assertions have been recognized as a supporting tool during software development, testing, and maintenance. Therefore, software developers place assertions within their code in positions that are considered to be error prone or that have the potential to lead to a software crash or failure. Similar to any other software, programs with assertions must be maintained. Depending on the type of modification applied to the modified program, assertions also might have to undergo some modifications. New assertions may also be introduced in the new version of the program, while some assertions can be kept the same. This paper presents a novel approach for test case prioritization during regression testing of programs that have assertions using fuzzy logic. The main objective of this approach is to prioritize the test cases according to their estimated potential in violating a given program assertion. To develop the proposed approach, we utilize fuzzy logic techniques to estimate the effectiveness of a given test case in violating an assertion based on the history of the test cases in previous testing operations. We have conducted a case study in which the proposed approach is applied to various programs, and the results are promising compared to untreated and randomly ordered test cases.

This study was done to investigate the relationship between indoor environmental quality and prevalence of Sick Building Syndrome in six small offices inPenangIsland. Indoor environmental quality measurement was conducted according to relevant standards. There are totally Sixty workers were selected to participate in an electronic questionnaire survey. Questionnaire was used to record the comfort level of respondents in the case studies and level of sick building syndrome faced by respondents. Through indoor environmental quality measurement, it is found that most of the offices facing the lighting and noise problem. The result from the questionnaire shows that in overall, the occupants satisfy with their working environment in term of indoor environmental quality although the result also shows the opinions of occupants on dissatisfaction on certain indoor environmental parameter according to case study. The study also found that most of the occupants feel drowsy and fatigue when they work within the offices. Besides, due to the difference of the indoor environmental quality of the buildings, the occupants are suffered from different symptoms of the sick building syndrome.

Abstract One strategy of communities to easily embrace ecological awareness is by involving directly in the improvement of their environmental quality. This paper discusses the case study research of the co-design process of the neighborhood regeneration project in Kampung Tongkol at the Ciliwung riverbank, Jakarta. This project is carried out collaboratively involving residents of the area and facilitated by ASF (Architecture Sans Frontières) Indonesia. The main important object of this regeneration project is the construction of a self-supporting sample house. This house aims as an ideal model which another neighborhood can replicate. Residents are directly involved in the organizing, the design process, to the construction stage. The primary purpose of regeneration is to improve the quality of the residential environment. The principles of sustainable design are employed as the main guidance from the beginning of the process. This study concludes that the final achievement of this project not only results in a higher quality environment but also raises the ecological awareness of the residents of the neighborhood.
