Moral reasoning in adaptation to climate change

Moral foundations theory argues that moral reasoning is widely observed and fundamental to the legitimacy of relevant governance and policy interventions. A new analytical framework to examine and test how moral reasoning underpins and legitimizes governance and practice on adaptation to climate change risks is proposed. It develops a typology of eight categories of vulnerability-based and system-based moral reasoning that pertain to the dilemmas around adaptation and examines the prevalence of these moral categories in public discourse about specific adaptation issues. The framework is tested using data on climate change impact, adaptation, and societal responsibility, drawn from 14 focus groups comprising 148 participants across the UK. Participants consistently use moral reasoning to explain their views on climate adaptation; these include both vulnerability-based and system-based framings. These findings explain public responses to adaptation options and governance, and have implications for the direction of adaptation policy, including understanding which types of reasoning support politically legitimate interventions.

The ecohealth system and the community engagement movement in foundations: A case study of mutual benefits from grants funded by the United Nations Foundation

Ecohealth is a process for identifying key environmental determinants causing mortality or morbidity and combating them by mobilizing multiple social sectors. Evolving out of the concept of environmental health, ecohealth provides a framework for long‐term sustainability. The health outcomes anticipated by environmental interventions are part of a long‐term agenda and require fundamental groundwork for the growth of community‐driven development. Building long‐term sustainability requires that two key approaches be developed through ecohealth. The first is the strengthening of local community institutions, whether formal or informal. The second is building financial mechanisms that are more diversified and less reliant on a single donor. As a result, the ecohealth system provides an opportunity for foundations to empower communities, build cross‐cutting cooperation, and gain knowledge through projects. If people's environmental behaviour is to change and be sustained in the long term to produce desired health outcomes, this will require all members of society to be capable of functioning within the existing institutional infrastructure. This means that not only do formal institutions need to become more accessible but also that concepts relating to local informal institutions must be incorporated into ecohealth projects. It is imperative that we identify and understand relevant local institutions and how they can be transformed so that new environmental forms of behaviour can be sustained and result in positive health outcomes. The intersection of environmental and health concerns provides an ideal area in which the gap between government and civil society can be bridged — not only providing solutions to ecohealth concerns, but building government capacity in general and making these positive changes sustainable in the long term. This article is a case study, based on several United Nations Foundation grants. It outlines the significance of traditional community organizations, the breadth of their long‐term relations with communities, their resources, and the adoption of sustained forms of behaviour. In addition, the article highlights the role that international foundations can play in creating innovative financing mechanisms through community‐based foundations.     

MPA法和Pushover法在掉层框架结构中的适用性对比分析

结合已有的规则结构分析结果,设置不同的掉层跨数、掉层数量的掉层结构,以逐步增量弹塑性时程分析(IDA)结果为依据,运用多模态Pushover法(MPA)和传统的Pushover法进行对比分析。结果表明:相对于规则框架结构,除MPA外,掉层结构的掉层部分在各类侧向力分布模式相对于IDA下的层间Pushover曲线有较大差异。SRSS分布下在掉一、二层位置,过高估计结构的响应。上接地层以上部位各侧向力下的层间Pushover曲线较IDA曲线误差较小。掉层的楼层的层剪力在上接地位置存在明显的突变。掉层跨数的改变对上部楼层弹塑性分析结果影响较小,但跨数的改变会改变同等烈度下结构的层间Pushover曲线和内力响应。与此同时,掉层跨数的增加会减轻"剪力突变"现象。伴随着掉层层数的增加,掉层部分均匀分布和倒三角分布与IDA下层间推覆曲线的差异会扩大。总之,相对于传统Pushover分析,MPA分析的结果更接近于相对准确值,需要进一步研究以提高精度。     

Moral dimensions of human–wildlife conflict

Despite increasing support for conservation globally, controversy over specific conservation policies persists among diverse stakeholders. Investigating the links between morals in relation to conservation can help increase understanding about why humans support or oppose policy, especially related to human–wildlife conflict or human conflict over wildlife. Yet the moral dimension of human–wildlife conflict has mostly gone unconsidered and unmeasured; thus, policy and programmatic efforts to reduce controversy may be missing a key part of the equation. We conducted a web‐based survey (n = 1239 respondents) in Michigan (U.S.A.) to investigate cognitive and emotional influences on the value–behavior relationship. Respondents were identified by their interest and involvement in Michigan wolf management. The survey consisted of questions about values, emotions, cognitions, and behaviors relative to wolves in Michigan. We used path analysis to explore whether emotions and cognitions mediated the relationship between value and behavior. Most respondents attributed intrinsic value to wolves (n = 734) and all life (n = 773) and engaged in behaviors that benefited wolf populations and ecosystems regardless of stakeholder group (e.g., environmentalist, farmer). Attributing intrinsic value to wolves was positively related to favorable emotions toward wolves and cognitive assessments that hunting and trapping of wolves is unacceptable. Despite similarities in attribution of intrinsic value, groups differed in emotions and cognitions about wolf hunting. These differences provide a useful way to predict stakeholder behavior. Our findings may inform interventions aimed at increasing support for wolf management policies and positive interactions among stakeholders and wildlife. Leveraging agreement over intrinsic value may foster cooperation among stakeholders and garner support for controversial conservation policy.

Is there a sustainability canon?

This paper identifies one possible set of appropriate disciplinary content for undergraduate programs in sustainability, based on a survey instrument employed at two international sustainability events in 2005. Undertaken to supplement the focus in the sustainability education literature on generic skills and pedagogical method via case-based or broadly conceptual work, it seeks to assist curriculum developers with planning disciplinary content. Findings indicate that a sustainability canon of sorts exists. A surprising amount of agreement existed from the two different specialist groups about core concepts, notably in ecology and—less unanimously—policy, economics and ethics. Studies about society were preferred as elective content. A 10-subject core was nominated, suggesting the need for broad foundational underpinnings.

高阶振型在山地掉层结构中的影响研究

设置不同掉层层数、掉层跨数和坎上楼层层数的模型,对比分析各模型在不同振型数下结构响应值的误差,根据分析结果来验证常用振型数量控制方法的适用性和差异性。结果表明,高阶振型对山地结构中掉层部分的内力响应影响显著。不同的掉层结构布置对振型数的选择有重要影响,掉层层数的增加使层剪力误差超限的楼层位置从顶层转移到掉层部分,致使掉层部分对高阶振型更加敏感。伴随着掉层跨数的减少,最大层剪力误差及误差超限的楼层数均呈先增大后减小趋势,即存在最不利的掉层跨数比,此时各内力响应误差均最大。坎上楼层的增加会提高掉层部分的剪力误差值。相对于层剪力,层间位移更易于通过提高振型数来控制精度。振型位移控制法的精度较高,但会增加大量结构计算和分析成本。振型质量参与系数法仅在个别结构中的层间剪力误差较小,总体来说其控制效果较差。解决这一问题,还需进一步研究以便提出一种新的振型控制方法。
