YN／变压器负序电流和谐波电流的分析

考虑二相负荷大小、功率因数变化,分析了ＹＮ／联结平衡变压器用于铁道牵引电站时一次侧的负序和谐波电流的变化规律。通过与ＹＮ／△接线变压器比较,说明ＹＮ／联结平衡变压器在减小电网负序和谐波电流方面具有很大优势。在牵引电站中使用该变压器能显著地提高牵引供电系统的技术和经济性能。     

I Will Follow: Smart Power and the Management of Wartime Alliances

Abstract

This paper employs the concept of smart power to construct an analytical framework for assessing wartime alliance management. It makes two arguments. First, wartime sources of soft power differ from those obtaining during peacetime. Second, the coerciveness with which an alliance leader wields hard power towards actual or prospective allies should vary inversely with the amount of soft power it possesses. The smart power framework illuminates three types of alliance management failure. The paper’s key contentions are illustrated with examples furnished from the record of US alliance leadership since World War II.

Walking a tightrope: the International Criminal Court and conflict prevention in Africa

Many African countries gained political independence in the 1960s. This era of independence came with promises and great expectations of economic, political and social development. Fifty years later, it is certain that the promises and expectations of independence have not been easily realised. Perennial violent conflicts have continued to ravage many countries in Africa, causing the catastrophic breakdown of law and order. Therefore, one of the major issues in conflict resolution discourse in Africa is how to develop functional mechanisms for the prevention of violent conflicts. This article examines the capacity of the International Criminal Court (ICC) to act as a mechanism for conflict prevention in Africa. Notwithstanding the doubts and uncertainties associated with the impact of law on conflict transformation, this article argues in the main that the ICC contributes to conflict prevention in Africa by expressing global norms of international law, challenging the culture of impunity in some countries, contributing to general deterrence, speedily intervening in some violent conflicts, and contributing to building some records of atrocities by identifying who did what.     

The International Conference on the Great Lakes Region

In April 2012 a number of former rebels who had been integrated into the Forces Armées de la République Démocratique du Congo (FARDC) mutinied and formed the Movement of March 23, better know as the M23 rebel group. The International Conference on the Great Lakes Region (ICGLR) has been mediating between Kinshasa and the M23 rebel group since 2012, without much success. In August 2013, the Southern African Development Community (SADC) issued a communiqué after its 33rd Summit of Heads of State and Government, stating that while it commends the ICGLR efforts, the talks have become protracted and a deadline needs to be set. The summit also called for an urgent joint ICGLR–SADC summit to address the crisis in the eastern Democratic Republic of Congo (DRC). In addition to this development, the chair of the ICGLR is to be rotated in December 2013, when President José Eduardo Dos Santos of Angola replaces President Yoweri Museveni of Uganda. To date, the mediation has been headed by Uganda and this has raised concerns over the credibility of the ICGLR-led process, since Uganda has been accused of supporting the M23 rebellion in a report released in November 2012 by the United Nations Group of Experts on the DRC. One could question whether the Angolan leadership will bring anything new that could have an impact on the crisis. Many expect that the perceived neutrality that Dos Santos could bring to the negotiations may be a positive step towards reviving the talks that have all but stalled at this point. Another issue of interest is whether the joint ICGLR–SADC summit could instil new life into the mediation process.

西方治安管理主体多元化探析

传统观念认为,政府警察机构是维护社会治安秩序的主体。然而,西方国家的治安管理实践表明,私人保安、社会自治组织等社会治安组织也参与社会治安管理工作,与警察机构合作、互动,共同维护社会秩序。治安管理主体呈现多元化的原因主要有三个方面:一是西方政府机制本身内在固有的缺陷导致警察机构治安服务失灵现象为其提供现实依据;二是新公共管理、自组织网络治理等理论为其产生提供理论基础;三是治安需求的多元化为其提供了发展的动力。     

Between Man and Nature: The Enduring Wisdom of Sir Halford J. Mackinder

This article argues for the continued relevance of the work and theories of the British Geostrategist Sir Halford J. Mackinder (1861-1947). It asserts that commentators and scholars who seek to marginalise Mackinder have too often dismissed his theories without setting them in the context of their continued endorsement in crucial areas of the globe. After 1945, despite his theories being tainted by association with Nazi Germany and Imperial Japan, both Moscow and Washington recognised the utility of Mackinder’s work and tailored policy accordingly. The end of Cold War saw Mackinder fall out of favour as his model was deemed unsuitable for policy analysis by a number of influential thinkers. It is argued here that, in recent years, the arena of international politics has seen a rehabilitation of Mackinder, accompanied by a resurgence of interest in Geopolitics. Finally, the piece examines those areas of the contemporary globe where Mackinder’s influence is greatest.     

Shifting power,preventive logic,and the response of the target: Germany,Russia, and the First World War

If a declining state has incentives for preventive war, the rising state should have incentives to delay a confrontation until it is stronger. We develop the theoretical paradox and examine the July 1914 crisis. Why did Russia, rising relative to Germany, not adopt a buying-time strategy? We argue that although most Russian leaders hoped to avoid a confrontation, they feared that the failure to support Serbia would lead to a loss of Russian credibility and a significant setback to Russia’s position in the Balkans, one that could not easily be reversed, even with Russia’s expected increase in relative military power.

抗日战争与中国大国地位的奠定

1937年芦沟桥事变后,以国共两党合作为基础的抗日民族统一战线正式建立,十年内战的分裂局面暂告结束。国共两党共赴国难,为世界认识中国、中国走向世界提供了一个平台。国共两党合作抗战,赢得了世界人民的同情和支持,也增强了民族的凝聚力。太平洋战争爆发,共同的利害关系把中、英、美联合到反法西斯战线上,历史给予中国改变自己国际地位的一个重要契机。中国在没有国际援助的情况下,独立与日本军国主义苦战四年半之久。中国在抗战中的表现,表明中国已经具备了一个大国的资格。罗斯福主张将中国列入“四强”。中国与美英并列参加开罗会议,表明中国的大国地位得到了国际承认。但是,抗战中中国国际地位的奠定并获得国际社会的承认,主要由于中国在世界反法西期战争中的重要作用和特殊地位,同时也出于美英战略的需要。应该说,中国国际地位的真正奠定并获得国际社会的真正承认是在新中国成立以后。

论管理者权力性非权力性影响力

管理是对部属施加影响以实现组织目标的过程。在这一过程中,无不体现着管理者权力性和非权力性的影响力。权力性影响力是由上级赋予管理者的职务、地位、权力等构成的;非权力性影响力是一种不依靠权力,而凭借个人的品德、才能、学识、情感、威信等而产生的一种影响他人,支配部属的力量。管理者应着力提高非权力性的影响力。

国际海洋法与维护国家海洋权益

海洋权益是指沿海国对属于自己的管辖海域享有国际海洋法所赋予的特定主权权利。《联合国海洋法公约》奠定了现代国际海洋法制度的基础,为各国维护正当的海洋权益提供了基本法律依据,但也有不完善甚至严重缺陷之处。认真研究其利弊,以切实维护国家海洋权益和公正合理的国际海洋法律秩序。
