基于车辆身份检测数据的车辆出行排放知识图谱研究

为实现个体车辆出行、排放行为的精细表征与挖掘,基于宣城市中心城区全量个体车辆的出行轨迹、技术参数、排放轨迹等多维交通大数据,以表征个体车辆出行过程的排放信息为主线,设计并构建车辆出行排放知识图谱.研究表明：①知识图谱直观地表征了“车辆-道路-出行-排放”信息的时空关联,可实现个体车辆在不同日期、不同时段、不同路段等多尺度出行特征的精细挖掘.以某辆小型客车为例,检索发现周一、周三出行主要连接的小时实体都为7：00、8：00和17：00,周五、非工作日出行连接的小时实体具有明显的随机性;周一、周三出行所连接的道路实体较少且基本一致,在宣水路、昭亭北路、昭亭南路的出行里程之和占比为63%~68%,周五、非工作日出行连接的道路实体则较为分散.②通过出行信息类、排放信息类实体的关联检索,可实现个体车辆出行排放时空特征的精细辨识和溯源分析.示例车辆的检索结果表明：周一车辆的CO日排放量为1.2g,是周六的2.5倍,同时在早高峰时段（7：00）,车辆出行在交通繁忙路段时,伴随低水平车速,排放强度相对较高.     

Operationalizing ecosystem service bundles for strategic sustainability planning: A participatory approach

The ecosystem service concept is recognized as a useful tool to support sustainability in decision-making. In this study, we collaborated with actors in the Helge å catchment, southern Sweden, in an iterative participatory ecosystem service assessment. Through workshops and interviews, we jointly decided which ecosystem services to assess and indicators to use in order to achieve a sense of ownership and a higher legitimacy of the assessment. Subsequently, we explored the landscape-level interactions between the 15 assessed services, and found that the area can be described using three distinct ecosystem service bundles. The iterative, participatory process strengthened our analysis and created a shared understanding and overview of the multifunctional landscape around Helge å among participants. Importantly, this allowed for the generated knowledge to impact local strategic sustainability planning. With this study, we illustrate how similar processes can support local decision-making for a more sustainable future.Electronic supplementary materialThe online version of this article (10.1007/s13280-020-01378-w) contains supplementary material, which is available to authorized users.     

Adaptive Process Control in Rubber Industry

This paper describes the problems and an adaptive solution for process control in rubber industry. We show that the human and economical benefits of an adaptive solution for the approximation of process parameters are very attractive.

The modeling of the industrial problem is done by the means of artificial neural networks. For the example of the extrusion of a rubber profile in tire production our method shows good resuits even using only a few training samples.     

Caring for country through participatory art: creating a boundary object for communicating Indigenous knowledge and values

The trend towards the inclusion of diverse groups in environmental decision-making has led to the need to explore new forms of communication to engage communities in expressing their values and aspirations. Participatory art as an emergent methodology was explored with Traditional Owner groups involved in policy development through the Girringun Aboriginal Corporation in northern Queensland, Australia. The works began with a moderated focus group exploring the theme What does caring for country mean to you? Participants then worked collaboratively on one canvas over some six weeks. Individual expressions were discussed with participants during and following their creation. Themes emerging from the focus group and painting workshop included those related to culture, well-being, environment, politics, and holism, which was central to the discussions. The common thread of the work was that people need to interact with country in order to care for country.     

Old ways for new days: Australian Indigenous peoples and climate change

ABSTRACT

This paper explores how Australia's Indigenous peoples understand and respond to climate change impacts on their traditional land and seas. Our results show that: (i) Indigenous peoples are observing modifications to their country due to climate change, and are doing so in both ancient and colonial time scales; (ii) the ways that climate change terminology is discursively understood and used is fundamental to achieving deep engagement and effective adaptive governance; (iii) Indigenous peoples in Australia exhibit a high level of agency via diverse approaches to climate adaptation; and (iv) humour is perceived as an important cultural component of engagement about climate change and adaptation. However, wider governance regimes consistently attempt to “upscale” Indigenous initiatives into their own culturally governed frameworks - or ignore them totally as they “don't fit” within neoliberal policy regimes. We argue that an opportunity exists to acknowledge the ways in which Indigenous peoples are agents of their own change, and to support the strategic localism of Indigenous adaptation approaches through tailored and place-based adaptation for traditional country.     

Using Visual Impact Metaphors to Stimulate Environmentally Friendly Behavior: The Roles of Response Efficacy and Evaluative Persuasion Knowledge

ABSTRACT

Although people often are aware of the importance of adopting environmentally friendly lifestyles, they might be reluctant to do so as they believe that their actions do not make a difference (i.e. low response efficacy). Furthermore, they might experience reactance (e.g. negative attitudes) towards environmental messages that encourage them to adopt an environmentally friendly lifestyle. Therefore we experimentally tested whether it is possible to stimulate people to adopt an environmentally friendly lifestyle (i.e. recycle more clothing) by using visual impact metaphors that convey the message that old clothes deserve a new life. The findings show that a message in the form of a visual impact metaphor (vs. no visual impact metaphor) results in more positive attitudes towards recycling and stronger recycling intentions. This effect was mediated by two different underlying mechanisms: Response efficacy and more positive attitudes towards the persuasive attempt (i.e. positive evaluative persuasion knowledge).     

Hunger amidst plenty: farmworker food insecurity and coping strategies in California

Farmworkers are often overlooked as producers and consumers of food; although farmworkers in California labour in some of the most productive agricultural regions in the world, they are largely food insecure. This paper investigates approaches to relieving farmworker food insecurity in one of the most productive agricultural regions in North America, California's Northern Central Coast. I explore the structural causes for farmworker food insecurity, looking at how farmworker food insecurity is linked to international trade and immigration policies, as well as the systematic exploitation of workers in California agriculture. Investigating the various ways that farmworkers cope with food insecurity, I compare two different approaches, food assistance programmes and farmworker gardens. I discuss the linkages between farmworkers' place in the food system as both producers and consumers, as they simultaneously are exploited for their labour and create their own coping mechanisms utilising their embodied agricultural knowledge.

A mixed methodology for evaluating use of evidence in conservation planning

Conservation practitioners widely recognize the importance of making decisions based on the best available evidence. However, the effectiveness of evidence use in conservation planning is rarely assessed, which limits opportunities to improve evidence-based practice. We devised a mixed methodology for empirically evaluating use of evidence that applies social science tools to systematically appraise what kinds of evidence are used in conservation planning, to what effect, and under what limitations. We applied our approach in a case study of the Nature Conservancy of Canada (NCC), a leading land conservation organization. We conducted qualitative and quantitative analyses of 65 NCC planning documents (n = 13 in-depth) to identify patterns in evidence use, and surveyed 35 conservation planners to examine experiences of and barriers to using evidence. Although claims in plans contained a wide range of evidence types, 26% of claims were not referenced or associated with an identifiable source. Lack of evidence use was particularly apparent in claims associated with direct threats, particularly those identified as low (71% coded as insufficient or lacking evidence) or medium (45%) threats. Survey participants described relying heavily on practitioner experience and highlighted capacity limitations and disciplinary gaps in expertise among planning teams as barriers to using evidence effectively. We found that although time-intensive, this approach yielded actionable recommendations for improving evidence use in NCC conservation plans. Similar mixed-method assessments may streamline the process by including interviews and refining the document analysis frames to target issues or sections of concern. We suggest our method provides an accessible and robust point of departure for conservation practitioners to evaluate whether the use of conservation planning reflects in-house standards and more broadly recognized best practices.     

The Boiling Liquid Expanding Vapour Explosion (BLEVE): A bibliometric review and futur trends

The phenomenon “Boiling Liquid Expanding Vapor Explosion” (BLEVE) is one of the most common accidental events in the chemical industry and in the transport of dangerous goods. A bibliographic search in the Web of Science Core Collection reported 375 publications related to BLEVEs from 1979 to the present (August 10, 2022). A bibliometric analysis was conducted using the VOSviewer tool to allow a better understanding of the scientific knowledge on this phenomenon. A comprehensive overview of BLEVE research is presented in terms of annual publication, top journals, countries/regions with the highest productivity, authors and their cooperation networks, key terms, and co-citation analysis. The 375 publications cover 691 authors, 83 journals, 44 countries or territories and 290 institutions. The key publication (highest number of citations and co-citations) for understanding the BLEVE phenomenon is. The results obtained constitute a snapshot of the current state of the art on BLEVEs and can be applied to improve the understanding of research on this topic and establish new trends of research.
