详细介绍了墨西哥哈利斯科州特拉凯帕凯市住宅开发区雨水收集系统的一种家庭模式.为了设计出一个可以为家庭提供最大水量的雨水收集系统,对雨水收集量进行了估算.基于估算出的雨水收集量,对家庭总需水量进行了计算,以便探讨雨水的可能用途.雨水收集系统的主要组成部分如下:集水区;落水管(屋顶排水管),第一冲洗水箱;水箱;渗井;泵站,过滤系统;紫外(UV)处理设备.雨水收集系统被设计成中央供水系统的一部分.介绍了雨水收集系统的设计和建设过程及其造价.通过该方式,可提供一个技术参考,从而帮助市民来设计和建设他们的雨水系统.该模式既可促进此系统在墨西哥的发展,也可为国际社会提供宝贵的经验. 相似文献

直觉模糊数是对传统模糊数的拓展,混合优先算子是对优先算子和加权算子的拓展.在直觉模糊的情形下,现实中针对实际活动中需要同时考虑准则之间具有不同优先级别和准则权重的多准则决策问题大量存在.本文基于直觉模糊优先算术平均(IFPWA)算子提出了直觉模糊混合优先算术平均(IFHPWA)算子;基于直觉模糊优先几何平均(IFPWG)算子提出了直觉模糊混合优先算术平均(IFHPWG)算子.这两种算子的特点不仅考虑到数据的重要性程度而且考虑到了准则的优先水平.在此基础上,提出了一种基于直觉模糊混合优先算子的多准则决策方法.该方法利用IFHPWA(IFHPWG)算子对数据信息进行加权集结,利用记分函数对方案进行排序并择优.最后,通过一个人才引进的实例分析,验证了所提决策方法的可行性和有效性. 相似文献

为提高城市绿道的雨洪调节功能,在文献研究和案例分析基础上,首先对城市绿道与低影响开发、绿色雨水基础设施的关系进行了分析.然后,提出了基于雨洪调节功能的城市绿道分类系统,总结适用于不同类型绿道的雨洪控制利用技术措施.结合中国城市规划体系,提出了与城市排水系统相结合的绿道规划方法,以及绿道雨水系统和单项雨水设施的设计方法,探讨了绿道雨水系统在入流、竖向、溢流等方面与其他系统的衔接关系.最后,介绍了上述规划设计方法在嘉兴滨水绿道和道路绿道示范项目中的应用,结果表明雨洪控制利用系统对年径流总量和年均污染物总量(TSS)的削减率分别不低于30%和40%. 相似文献

The relationship between sustainability and the Anthropocene takes on new meaning in a time of unprecedented human impact on Earth systems. This relationship is at times contested and not well researched but critical in considering how we will respond to environmental challenges of today and the future. Elaborating on the need for new perspectives and nuanced understandings of sustainability, the contributors to this volume draw on posthumanist and “new” feminist materialist methodologies and theoretical lenses to engage readers in ways, which often contrast with prevailing thinking and research. From the cosmopolitics of place in urban Berlin to the watery space of urban wetlands they share research and rich narratives, which illustrate how sustainability is theorized and enacted across a range of diverse educational contexts. Moving beyond the rhetoric of sustainability, the authors invite us to explore innovative ways to engage with new concepts and emerging tensions that are now influencing the fields of education and sustainability. 相似文献

This article demonstrates the educational value of an undergraduate course that integrates design and the liberal arts to
teach about ecological systems, using study of the university campus as the means to connect theory and practice. It presents
the curricular goals, objectives, results, and lessons learned from a qualitative case study of a cross-disciplinary course
that required design and liberal arts students to develop innovative solutions to improve the sustainability of The New School’s
food system. Student and faculty evaluations suggest that an integrated design and liberal arts course can be an effective
and enjoyable method to learn about sustainability and urban systems; and it helps students learn different techniques for
research, problem-solving, and communication. 相似文献

ABSTRACTAlthough academic staff have a key role to play in innovation at higher education institutions (hEIs), current innovation adoption among academic staff is disappointing. Most curricula at hEIs are stalled in the traditional pedagogical model of knowledge transmission for teaching and learning with little exploration of technologies for innovative/inventive outputs. This article explores the essential issues of innovation/invention in higher education and provides criteria for empowering innovation. Starting from reflections and perspectives on innovation at South African hEIs and the theories on innovative problem solving, the article provides arguments on multiple issues of innovation/invention that culminate in crucial criteria for innovation. The real dilemma for innovation is caused by external and macro-level factors that require the analysis of existing business models. The management of HEIs have to take into account the underlying barriers, such as knowledge of patenting and academic valorisation, when they create policies that encourage academic staff to explore innovative endeavours. 相似文献

The future of educational change: system thinkers in action 总被引：2，自引：0，他引：2
Michael Fullan 《Journal of Educational Change》2006,7(3):113-122
In addressing the future agenda of educational change, this paper advances the notion of sustainability as a key factor in developing a new kind of leadership. This new leadership, if enduring, large scale change is desired, needs to go beyond the successes of increasing student achievement and move toward leading organizations to sustainability. Currently, there is a lack of development of leaders toward system thinking. An argument is made for linking systems thinking with sustainability in order to transform an organization or a system. In order to accomplish this goal, it is necessary to change not only individuals but also systems. The way to change systems is to foster the development of practitioners who are “system thinkers in action.” Such leaders widen their sphere of engagement by interacting with other schools in a process we call lateral capacity building. When several leaders act this way they actually change the context in which they work. Eight elements of sustainability, which will enable leaders to become more effective at leading organizations toward sustainability, are presented. Within the explication of the eight elements, prior research is considered, difficulties are surfaced, and challenges are issued to change contextual conditions in order to effect large scale, sustainable educational change.Adapted from an address at American Educational Research Association Annual Meeting, 2004. 相似文献

This paper is an attempt to review the state of environmental education from the viewpoint of one involved in international and national strategies for its development. It relates environment and education to the whole system of human‐environment relationships and sees environmental education not as a separable package but as a movement for fundamental educational reform, in a rapidly changing world under increasing stress both from human‐induced change and from human nature itself. Environmental education has grown through the promotion of innovative educational approaches and the increasing attention given to human aspects of the system. Some of these, notably the idea of sustainability, need further development and careful use. Much work is needed to bring environmental and social systems together into a single conceptual structure, and to keep the development clear of misconceptions which are none of its making, to tackle the global issues that challenge survival and yet to remain realistic and practicable within the system in which it must work. 相似文献
