上海跨国迁移与流动人口的实证研究——以在沪日本人和赴日返沪人员为例

经济全球化推动了人们生产和生活方式、社会关系、文化模式的发展变迁，也使跨国迁移成为越来越频繁的“常态”。本文通过大量的数据和调查资料，以在沪日本和赴日返沪人员为例，对其历史沿革、人口结构、入出境事由、迁移类型和迁移方式、社会支持网络等问题进行了实证研究，并对二者的异同点进行了初步探讨。

Identification and assessment of aquatic resources for power plant sites on Maryland's Eastern shore

Abstract

A power plant siting procedure which accounts for the protection and preservation of aquatic resources, defined as sensitive life forms and life stages of economically valuable species of finfish and shellfish, is presented as it was executed on Maryland's Eastern Shore. Negative effects of power plant development and operation are generated principally by the cooling water intake and discharge system. The site‐selection procedure is thus presented as a two‐faceted process, termed regional screening, requiring the separate but simultaneous identification of land‐based sites and cooling systems. Criteria included in regional screening for cooling systems reflected life‐sustaining processes essential to the maintenance of aquatic resources. Major sources of effects of power plants on aquatic resources and siting principles as they affect aquatic resources are defined. Information‐gathering techniques included extensive interviews with key research scientists, state personnel, and numerous Chesapeake Bay watermen.

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.     

日本物流调查的经验与借鉴

物流调查是物流设施规划与政策制定的重要基础。物流数据统计发展滞后已成为制约中国物流业发展的重要瓶颈。通过梳理日本在物流调查方面的工作进展,总结其在调查制度保障、组织模式、调查方案、调查内容及方法等方面的特点。针对中国物流行业发展现状,提出具体建议:加快开展货运需求调查的前瞻性研究,规范并指导企业构建统一的物流信息数据与平台,远期将货运调查纳入综合交通调查体系等。
