‘I just hope people can forgive me’: Australian women athletes,apologies and image restoration at the Rio Olympic Games

Prior to the 2016 Olympic Games, Australia’s Chef de Mission Kitty Chiller predicted that the Australian team could win as many as 16 Olympic gold medals. Australia’s Olympic team won a total of eight gold medals and the sports media reacted by suggesting the team had ‘failed’. At the 2016 Olympic Games, three high-profile Australian female athletes apologised to the Australian public for their performances. This study examines these three interconnecting cases and how such behaviour is linked to research that examines sports media and gender (including female agency), ‘image restoration’ and third-wave feminism. Additionally, this work identifies how the culture of third-wave feminism is conceptually troubled by the notion of the ‘female apologetic’ and calls for a re-examination and modification of such a notion.     

基于底线预警的国土空间生态修复规划实施监督体系研究

国土空间生态修复是推进生态文明建设的重大举措，构建基于底线预警的国土空间生态修复规划实施监督体系是完善国土空间规划“一张图”信息系统的重要组成部分和政策支撑。通过对生态修复规划实施监督体系建设的研究，把握底线控制与监测预警机制，对接国土空间生态修复业务管理各项需求，搭建“五梯度四体系”的生态修复规划动态监测实施监督信息系统，构建以“七个一”为主要内容的生态修复规划底线预警监测评估机制，并与各层级国土空间规划“一张图”实施监督信息系统进行衔接，实现对生态修复规划实施的动态监测和预警。     

Impact mitigation or ecological restoration? Examining the environmental sustainability practices of multinational mining companies

This paper examines the environmental sustainability practices of multinational mining companies in addressing their impacts and promoting the sustainable development of local communities in Ghana. Although large-scale mining companies have embraced environmental sustainability, the drivers and the mechanisms for addressing their impacts throughout the mine life cycle is not fully understood because of the limited research in this area. The focus in this study involves an examination of the drivers for environmental sustainability in a weak and non-enabling institutional context and the mechanisms for addressing impacts on biodiversity, water quality and quantity, and ambient climate. The findings show that the environmental sustainability practices of multinational mining companies are determined by regulatory compliance and corporate environmental responsibility based on perceived ethical obligation. Additionally, we find gaps in mine closure planning and rehabilitation because of the limited requirement for biodiversity restoration in the domains of flora repopulation and active fauna reintroduction. This paper provides empirical and theoretical insights for academics and practitioners in industry and policymaking.     

Computing the Gerber–Shiu function by frame duality projection

Inspired by some works of Kirkby, J. L. [2015. Efficient option pricing by frame duality with the fast Fourier transform. SIAM Journal on Financial Mathematics 6(1), 713–747; 2016. An efficient transform method for Asian option pricing. SIAM Journal on Financial Mathematics 7(1), 845–892], we present a systematic study on effectively computing the Gerber–Shiu function in the Lévy risk model, where the frame duality projection is used for approximation. By introducing an auxiliary function, we provide a smooth extension of the Gerber–Shiu function, which has closed-form Fourier transform and is differentiable over the whole real line under some conditions. The objective function is approximated by its frame duality projection onto a Riesz basis, and the projection coefficients are readily computed by the fast Fourier transform algorithm. Error analysis is made and the effectiveness of our results will be further illustrated in the numerical experiments.     

基于ANP-PP-SPA的区域洪灾风险评价模型研究

针对现有洪灾风险评价模型的缺陷与不足,从致灾因子、孕灾因子、承灾因子和减灾因子4个方面,通过对14项评价指标的分析与计算,构建洪灾风险评价体系。洪灾风险评价体系以网络层次分析法(ANP)求解主观权重,投影寻踪法(PP)求解客观权重,主客观综合权重与集对分析理论(SPA)耦合,构建基于ANP-PP-SPA的洪灾风险评价模型。以广东省英德市为例,验证洪灾风险评价模型的适用性。计算结果表明,英德市2016年的洪灾风险属于中等级别,符合英德市2016年的实际情况。洪灾风险评价模型不仅综合考虑了评价指标间的相互关系,还较好地体现了洪灾风险的模糊性和随机性,能够为区域洪灾风险决策和洪水管理提供科学依据。     

Five scale challenges in Ecuadorian forest and landscape restoration governance

The forest and landscape restoration (FLR) targets set as part of the Bonn Challenge draw attention to the governance arrangements required to translate national FLR targets into local action. To achieve the targets, actors at multiple levels of the governance scale aim to influence relevant processes on the ecological scale. In this article, we focus on the scale challenges relating to the implementation of Ecuador’s restoration targets, by analysing the implementation of the 2014–2017 National Forest Restoration Plan in the montane Chocó Andino and Bosque Seco landscapes. From 54 semi-structured interviews, a document review, and geographical data analysis, we identified two temporal (i, ii) and three spatial scale challenges (iii, iv, v): i) Political cycles mismatch with FLR timelines; ii) Planning horizons mismatch with FLR timelines; iii) National restoration objectives mismatch with decentralised land use planning realities; iv) The governance level of existing FLR efforts mismatches with the level receiving restoration funds; and v) Tensions exist between the spatial dimensions of biodiversity and water-related restoration efforts. The findings highlight that more attention must be given to scale-sensitive governance to make the process in which national FLR targets are translated into local action more effective.     

基于IPA分析的西安江村沟垃圾填埋场 景观生态修复策略

通过对西安江村沟垃圾填埋场内及周边村民生活生产区共57处土壤进行实测与问卷调查，运用IPA分析方法，从村民景观生态感知角度出发，探讨村民对周边垃圾填埋场实际景观生态感知与期望之间的关系，以及影响村民景观生态感知的重要因素，得出景观生态满意度模型。对影响景观生态感知因素的重要性与满意度进行测量，同时生成IPA表现值与期望值，并以此为依据结合土壤实验结论，运用景观生态恢复技术，对垃圾填埋场的景观生态恢复提出了相关设计策略。

珠江三角洲地区变水位滨河地区生态修复与景观营造——以佛山市东平河景观工程为例

城市滨水地区是城市生态资源、景观资源和市民活动的重点区域。以广东佛山东平河为例,首先对场地中水利建设对变水位下河滩、堤岸、植被的影响做了分析,并针对洪水、潮汐的不同影响程度采取了相应的分级设计模型构想。在实践中,根据不同水位情况,运用低洼高筑、水道疏浚、植被恢复等多种方式,通过工程、生态、景观的手段恢复了滨水自然生境,营造了活跃的公共空间,实现了水利堤岸改造、生态修复、景观营造的有机结合,让陆地和水域自然衔接、和谐共生。
