A balancing act in urban social-ecology: human appreciation,ponds and dragonflies

Green spaces in cities provide cultural ecosystems services (CES) such as nature connection, wildlife interaction and aesthetic appreciation which can improve aspects of human well-being. Recognising these benefits, researchers are now examining the complex relationship between humans and nature in urban social-ecology. Most studies investigate people’s appreciation and valuation of different green space features and their contribution to urban biodiversity. Recommendations arising from such studies are best practices to achieve a balance between landscape aesthetic and ecological objectives, but many knowledge gaps still exist. In a social-ecological project in Greater London, appreciation of ponds and dragonflies in urban green spaces, and the environmental factors determining dragonfly diversity were investigated. We found ponds and their appearance were valued by people as enhancing their green space experience. The preference for wild-looking ponds was moderate. Dragonflies were enjoyed for their colour and high visibility, especially by those who had basic dragonfly knowledge. Species richness of dragonflies was positively associated with habitat heterogeneity in and around a pond. However, people were unable to relate a heterogeneous pond to more dragonfly species. For the first time, some factors that influence the human appreciation-ponds-dragonflies (HPD) relationship in an urban context are revealed. To fully realise the CES potential of ponds and dragonflies in Greater London, a HPD framework is proposed. The framework underpins strategies that foster cultural sustainability for ponds and dragonfly conservation.     

珠江三角洲城市社会极化与新型城镇化路径选择

城市社会极化是城市社会分异的不平衡和极端状态,不同的城镇化路径选择,将直接影响到城市社会分异和极化程度。改革开放以来珠三角的城市社会分异持续加速,出现了越来越明显的城市社会极化现象,并引发了一系列社会民生问题。显然,传统的以经济发展为导向、忽略人与社会发展的城镇化路径是其产生的重要原因。本研究从城市社会极化的视角出发,通过对珠三角城市社会极化现象及其产生的社会民生问题的分析,对传统城镇化路径中出现的问题进行反思,并以此为基础提出新型城镇化路径选择的方向。     

Two new estimators for the proportion of true null hypotheses in multiple test

In multiple hypothesis test, an important problem is estimating the proportion of true null hypotheses. Existing methods are mainly based on the p-values of the single tests. In this paper, we propose two new estimations for this proportion. One is a natural extension of the commonly used methods based on p-values and the other is based on a mixed distribution. Simulations show that the first method is comparable with existing methods and performs better under some cases. And the method based on a mixed distribution can get accurate estimators even if the variance of data is large or the difference between the null hypothesis and alternative hypothesis is very small.     

The classing gaze and its gendering effects: (dis)‐respectability,emotional (in)‐competency,and the counselling experiences of domestically violent Taiwanese men

Research on domestically violent men typically takes an oppositional logic of gender. While the significance of class in researching domestically violent men is identified, class and gender are often treated as separate entities that do not complicate each other. Drawing upon group observations and in‐depth interviews, this paper identifies how intersections of class and gender manifest in the counselling experiences of domestically violent Taiwanese men. From a Bourdieusian feminist analysis, the authors analyse (1) how class distinctions serve to (re)produce gendered hierarchy; (2) how contradictory experiences of gender reveal a relational understanding of class; and (3) how the gendered nature of domestically violent men is inscribed with a meaning of (working) class specificity for maintaining middle‐class ‘purity’. In analysing men's multiple and conflicting experiences, this paper contributes to research on domestically violent men by showing how class and gender are actively constructed and not produced in a monolithic/invariant way.

流浪儿童救助保护体系的构建原则

当前,中国流浪儿童救助保护的理论与实践都取得了显著进展。然而,在这一领域中,国家——社会关系、体制内的机构救助者和民间主体如何分工、两者关系如何调适等方面尚未形成学界共识。因此,对中国流浪儿童救助保护体系的构建原则进行讨论很有必要。构建流浪儿童救助保护体系应包括五个原则,即政府依然要扮演主要角色、社会力量的有效参与不可或缺、专业社会工作与本土社会工作相结合、档案管理与因人施“救”、对流浪儿童实施主动性救助保护等方面。
