邻里合乘——社区拼车常态化的探索

为了促进邻里合乘社区拼车模式不断完善以及有效推广实践、实现社区拼车常态化发展,在分析我国拼车发展现状与困境的基础上,探讨了邻里合乘社区拼车的创新理念,包括社区组织、法律支持、签订协议、社会参与四个方面。针对存在的拼车协议缺陷、拼车对象受限难推广的局限,提出邻里合乘的发展建议：扩大活动影响,寻求政策支持,从根本上突破法律等制度的困境;建立由政府支持的社区拼车试点计划,逐步将社区拼车模式推广,最终实现社区全民拼车的常态化。     

Community Perceptions of a World Heritage Nomination Process: The Ningaloo Coast Region of Western Australia

The remote Ningaloo Coast region, the location of Australia's largest fringing coral reef, was designated as World Heritage (WH) in 2011 based on its outstanding natural values. In the past, the WH nomination process predominantly involved experts and state officials. More recently, local community involvement has become a required part of the process, representing a move toward participatory governance that can potentially influence WH designation. Understanding community perceptions of the WH nomination process provides insights into the consequences of community involvement. Interviews were conducted with key local community members involved in the Ningaloo Coast WH nomination. Interviews focused on the perceptions and experience of the nomination process and local meanings of WH designation. Results indicated that while there was support for WH designation, the nomination process was seen as controversial. Community involvement was dominated by local political and social concerns, mistrust, misinformation, and perceived unfairness. Concerns were influenced by past and current government actions and decision-making in the region. The article identifies some challenges associated with local community involvement in a WH nomination process. These challenges raise questions about participatory governance and how local community's engage in the WH nomination process for coastal regions identified by experts as globally significant.

Limitation of egg production in Calanus finmarchicus in the field: A stoichiometric analysis

The egg production of marine copepods correlates with a range of variables, including the availability of organic carbon (C), nitrogen (N) and the polyunsaturated fatty acids (PUFAs) 20:5(n−3) (EPA) and 22:6(n−3) (DHA). However, an understanding of which substrates limit egg production in the natural environment has yet to be reached. The quantities of C, N, EPA and DHA ingested, derived from parental biomass, and invested in eggs by female Calanus finmarchicus during a 5-day incubation experiment were examined using stoichiometric theory to determine which substrate was limiting. The majority of each substrate was derived from parental biomass, and therefore the existing stoichiometric theory is developed to include this route of supply. The females were essentially devoid of lipid reserves, as evidenced by the lack of the storage fatty acids 20:1(n−9) and 22:1(n−11), and carbon limitation was predicted under most of the scenarios examined. Nitrogen limitation was only apparent when carbon and nitrogen utilisation efficiencies were assumed to be high (0.5) and low (0.4) respectively. PUFAs were assumed to be utilised with high efficiency (0.9), and were never predicted to limit production. This work highlights the need for a more detailed understanding of the maintenance requirements that marine copepods have for C, N, EPA, and DHA and hence the efficiencies with these substrates can be utilised for growth.     

Spatial and temporal variability in the pelagic ecosystem of the East Sea (Sea of Japan): A review

The East Sea (Sea of Japan) is a unique marginal sea because it exhibits features of oceanic dynamics of much larger ocean basins. This semi-enclosed basin may be considered as a model or microcosm for understanding of how biological processes and distributions in pelagic ecosystem are interacting with physical processes in highly dynamic ocean regions. This overview summarizes the recent progresses concerning spatial and temporal variability of pelagic ecosystem components form an interdisciplinary point of view. Spatial characteristics of physical environments and biogeography in the region are distinguished mainly by the subpolar front. It was also found that long-term changes in biomass and community structure as well as those in the physical and biological environments are associated with climate variability in the region. We conclude by identifying main needs for the information and researches, particularly regular and long-term sampling, and permanent monitoring if possible.     

The influence of neighborhood types on active transport in China’s growing cities

Rapid urban expansion in China has created both opportunities and challenges for promoting active transport in urban residential communities. Previous studies have shown that the urban form at the city scale has affected active transport in Chinese cities. However, there is less agreement about how the physical and social variations of neighborhood types should be addressed. This research investigates the four most representative neighborhood types found in Chinese cities: traditional mixed-use, slab block work-unit, gated community, and resettlement housing. Household travel diaries conducted in Chengdu in 2016 were analyzed using binary logistic regressions, supplemented by informal onsite interviews. The findings indicate significant variations in the use and accessibility of active transport in each neighborhood type for non-work trips. This suggests that each neighborhood type may need different strategies for promoting active transport: (1) the traditional mixed-use neighborhoods are in need of intensified urban retrofitting projects to reclaim public open space; (2) the work-unit could benefit from comprehensive plans rather than a patchwork of projects; (3) while opening up gated communities can improve porosity across neighborhoods and promote active transport, the more pressing issue may be their inability to keep up with the transportation needs of the residents; and (4) residents of resettlement housing should have better access to employment using transit and non-motorized modes.
