金砖国家非传统安全合作的理论与实践路径

围绕金砖国家合作,不少人持有"褪色论"或"金砖分化"的悲观态度,主要论据是金砖国家之间并不存在很强的禀赋互补性,因而难以促成合作。然而,从合作理论和非传统安全问题的治理实践出发,金砖国家合作都是可行的。从理论维度出发,合作包括交换型合作与协作型合作。交换型合作认为,禀赋的互补性缺失,合作就难以形成。这也是当前学界对于金砖合作的争论焦点。然而,合作还包括协作型合作,达成共同利益,并不依赖禀赋的互补性就能塑造相互依赖的合作关系。再回到金砖国家在非传统安全问题领域内合作实践的维度,随着安全的内涵、议程和治理路径发生转变,国与国之间的共同利益越来越多。因为全球化时代安全议程空前复杂、具有非传统性,进而超越了一国之能力予以治理。具体到金砖合作的治理实践之中,塑造后天共同利益的操作路径包括:塑造"行动焦点"、把饼做大;培育信任、塑造伙伴关系等。此外,金砖国家合作强调包容性规范,持开放的姿态,重视与其他平台以及世界各国的合作。     

The impacts of welfare reform on recipients of housing assistance

Abstract

This article uses data from randomized evaluations in Indiana and Delaware to address three questions: (1) Are welfare recipients who receive federal housing assistance less employable than recipients who do not? (2) How does the impact of welfare reform compare for families with and without housing assistance? (3) Does welfare reform increase or decrease the use of such assistance?

Although public housing residents may be more disadvantaged than welfare recipients who do not get housing assistance, voucher users and Section 8 project‐based recipients were not. Welfare reform had similar impacts on the earnings and welfare benefits of families that received housing assistance and those that did not. Where impacts did differ, they were larger for families receiving assistance. Welfare reform also reduced the receipt of housing assistance. Families that receive assistance appear to have less financial strain than families that do not, suggesting that assistance may increase overall financial stability.     

中美在亚太地区的安全矛盾：演变与逻辑

近年来,中美在亚太地区的安全矛盾持续发酵,逐渐形成安全利益、理念和地区安全秩序构想的全面对立态势,成为影响中美和平共处的重要因素。秩序疑虑与热点问题的对立是中美在亚太地区安全矛盾的主要表现。中美亚太安全矛盾的全方位突显,根本上源于两国力量对比的变化以及由此引发的权力转移态势,是中美总体力量差距背景下局部力量平衡的表现。这种力量平衡表现为:中国作为地区经济中心与美国作为地区安全中心的“二元结构平衡”;中国作为陆权大国与美国作为海权大国的“陆海权力平衡”;在中国近海区域,中美权力均衡态势初步形成。在此过程中,中美对既有安全矛盾管理的失效以及彼此安全威胁认知的反复塑造,客观上增强了矛盾对立的烈度,安全困境逐步形成。随着权力消长和政策互动,中美在亚太地区的安全困境,逐步呈现出从经典安全困境转向“国家引导型的安全困境”加剧的趋势。未来,中美亚太安全矛盾仍然会受到结构性因素的影响,而经济相互依存趋势、技术发展引发的军事威慑变化、意识形态竞争以及非传统安全合作等因素,则将决定既有安全矛盾是否会走向冲突。     

Extending appropriate technology to rural African women

The vital role of women in the agricultural sector in Africa is gaining wider recognition. It is now apparent that although women are actively engaged in agriculture, they are often denied information on modern agricultural practices.Besides farming, women have other arduous responsibilities. Appropriate technologies of all kinds have been developed to lessen the time women spend on nonproductive tasks, assist them with processing and preserving foods and equip them with income-yielding skills.University Departments of Home Economics can extend the benefits of appropriate technology to village women in several ways. They can carry on research studies in collaboration with international agencies. They can revise their syllabi to include appropriate technology and make agricultural subjects a requirement in the Home Economics Extension Programme. Students can be given more research and practical projects related to appropriate technology. Lastly, universities can set up Appropriate Technology Centres for the benefit of contiguous communities.
