论专属经济区的国家主权权利

1982年《联合国海洋法公约》确立了专属经济区制度，规定了沿海国对200海里专属经济区享有公约规定的主权权利和管辖权。专属经济区是一个既不同于公海又有别于领海的特殊海域，沿海国家对专属经济区的主权权利是国家经济主权的组成部分，公约的规定是尊重国家主权的。我们应充分利用公约的规定，积极维护我国专属经济区的国家主权权利。     

The water is not empty: cross‐cultural issues in conceptualising sea space

This paper provides an analysis of the neglect and marginalisation of indigenous peoples’ sea rights. It aims to explain how a complex and ecologically appropriate alternative law of the sea has largely escaped research interests and, until recently, has not been recognised by western systems of law and resource and environmental management. It is argued that the dominance of western views and concepts of nature and landscape predicated on western knowledge and values marginalises indigenous concepts of nature and undermines effective indigenous control of social space. Cultural differences between Aboriginal and non‐Aboriginal ways of constructing meaning in the sea provide the vantage point from which to explore the relations between differences in cultural values, property rights, and political and economic control over marine and coastal environments.     

(ANTI)SOCIAL CAPITAL IN THE PRODUCTION OF AN (UN)CIVIL SOCIETY IN PAKISTAN*

ABSTRACT. Pakistan is home to some of the most widely admired examples of civil‐society‐based service‐delivery and advocacy groups. Pakistan has also spawned some much‐maligned nongovernmental actors with violent agendas. This article uses the social capital / civil society conceptual lens to view the modes of (anti)social capital mobilization that contribute to the civil and uncivil spaces of Pakistani society. The case examples of Jamaat‐e‐Islami, an Islamic revivalist organization, and the Human Rights Commission of Pakistan are used to understand the geography of social and antisocial forces in Pakistan. It is argued that the processes that mobilize social capital‐whether positive or perverse‐are multiscalar and that, in the Pakistani context, no compelling cultural or religious reason exists for the ascendance of one type of social capital over the other. Positive social capital can be mobilized to contribute to a more civil social discourse in Pakistan, given the right policy choices.     

SEPARATE BUT EQUAL? DESEGREGATING BALTIMORE'S GOLF COURSES*

ABSTRACT. Between the time of its opening, in 1923, and 1956, when the last vestiges of official segregation were swept away by the courts, the Carroll Park Municipal Golf Course in Baltimore, Maryland, figured prominently in the struggle to desegregate the city's recreational facilities. In this article we use historical sources to examine how access to Carroll Park was shaped by issues of race and ethnicity during the first half of the twentieth century, focusing specifically on the role the park played in the struggle to desegregate Baltimore's golf courses. We also consider how this victory ultimately contributed to desegregation at the city's other recreational facilities, including ball fields and swimming pools.     

A collective human mobility analysis method based on data usage detail records

Human mobility patterns have been widely investigated due to their application in a wide variety of fields, for example urban planning and epidemiology. Many studies have introduced spatial networks into human mobility analyses at the collective level. However, these studies merely analyzed spatial network structure, and the underlying collective mobility patterns were not further discussed. In this paper, we propose a collective mobility discovery method based on community differences (CMDCD). We constructed spatial networks where nodes represent geographical entities and edge weights denote collective mobility intensity between geographical entities. The differences between communities detected from the networks constructed in different periods were then identified. Since collective spatial movement has a large influence on network structure, we can discover groups with different mobility patterns based on community differences. By applying the method to data usage detail records collected from the cellular networks in a city of China, we analyzed different collective mobility patterns between the Spring Festival vacation and workdays. The experimental results show that our method can solve these two problems of identifying community differences and discovering users with different mobility patterns simultaneously. Moreover, the CMDCD method is an integrated approach to discover groups whose mobility patterns have changed in different periods at the large spatial scale and the small spatial scale. The discovered collective mobility patterns can be used to guide urban planning, traffic forecasting, urban resource allocation, providing new insights into human mobility patterns and spatial interaction analyses.

深度学习在海珠国家湿地公园统一确权调查中的应用

针对自然资源调查中单一数据源难以兼顾地物空间与光谱属性的问题,本文提出了基于深度学习的数据融合分类方法。该方法利用多源数据有限样本,实现了植被覆盖区精细化分类;并以广东海珠国家湿地公园为试点,完成了示范区内自然资源类型提取,以及植被数量与质量调查。试验结果表明,该方法可有效实现自然资源类型提取与植被分类,林木数量探测正确率优于87%,显著提升了植被分类精细度,探索了基于精细化调查的自然确权登记途径。
