The British Government never recognized the Soviet annexation of the Baltic States in June 1940, but almost did so early in 1942 and was ready to do so again in 1944, when it took at face value Stalin's revision of the Soviet constitution. The result was ‘trouble’ from the Baltic ambassadors in London, particularly the Latvian ambassador. The British Government changed its stance in autumn 1945 when the revisions to the Soviet constitution proved to be sham. Thereafter British policy amounted to procrastination, as the developing Cold War prevented a final post-war settlement.  相似文献

U.S. citizens who marry foreign nationals may petition for their spouses so that the couple can reside permanently together in the United States. The guidelines set forth in the U.S. Citizenship and Immigration Services Adjudicator's Field Manual provide guidance to immigration officials for determining whether to grant or deny spousal petitions. Previously, the Adjudicator's Field Manual imposed a requirement that transgender individuals undergo costly and dangerous sex reassignment surgery in order to qualify as married for the purposes of a spousal petition. However, revisions to the Adjudicator's Field Manual issued in April 2012 provide transgender binational couples the opportunity to remain together in the United States without forcing one partner to undergo sex reassignment surgery. Given the history of discrimination against transgender individuals under U.S. immigration law, these revisions are a significant step in equality for transgender couples. Although these revisions provide many transgender binational couples with a means to remain together in the United States, this Note proposes that, to continue on the path toward equality for transgender couples, special guidelines should not be applied to marriages involving transgender partners if their marriage is deemed a valid heterosexual marriage in the state where solemnized. The goals of U.S. immigration law and compliance with the federal definition of marriage can be achieved without implementing individualized guidelines for transgender binational couples.
    Key Points for the Family Court Community:
  • Transgender spouses of a binational couple should not be subjected to additional guidelines when submitting spousal petitions that, if granted, would afford the couple the opportunity to reside together in the United States
  • Transgender individuals should not be subjected to disparate treatment solely because the U.S. Citizenship and Immigration Services seeks to enforce discriminatory provisions of the Defense of Marriage Act
  • A marriage should be recognized by immigration law if it is a valid marriage under the law of the state where the marriage was celebrated
  • In order to achieve U.S. immigration law's mission of family unification, nontraditional couples should be afforded the same opportunity to remain together in the United States without additional scrutiny

This case study illustrates the use of the date function on an automatic wristwatch to help identify a Vietnam War helicopter crash site. The location of a crash incident can sometimes be uncertain because of inadequate or inaccurate wartime records and the passage of time. Artifacts recovered from a prospective crash scene are regularly used to correlate the loss incident. In this case study, a recovered automatic watch displayed a date 2 days later than the reported loss incident. Although the date conflicts with the aircraft crash incident report, it is observed that a fully wound automatic watch continues to work for c. 2 days after movement of the watch ceases. Thus, the watch's date in fact correlates with the aircraft crash incident report. It is noted that automatic watches may also be used to date scenes of crime.  相似文献

Sequencing mitochondrial DNA hypervariable regions I and II (HVI and HVII) is useful in forensic missing person and unidentified remains cases. Improvements in ease and sensitivity of testing will yield results from more samples in a timely fashion. Routinely, amplification of HVI and HVII is followed by Sanger sequencing using the BigDye® Terminator v3.1 Cycle Sequencing kit (Applied Biosystems) using 4 μL of ready reaction mix (RRM). Each sequencing reaction is then purified through column filtration before capillary electrophoresis. Using lower amounts of RRM (2 μL or 1 μL) and purification using BigDye® XTerminator? (Applied Biosystems) instead of columns showed no loss of sequence length and increased the quality and the sensitivity of testing, allowing HVI and HVII typing from mitochondrial genome equivalent to 125 fg of nuclear DNA, or 100 pg of HVI/HVII amplicons. Using this methodology, testing can be completed in 1 day, and the cost of testing is reduced.  相似文献

霸权护持是霸权国在霸权周期内的主要战略目标。通过考察二战结束以来美国霸权护持的历史轨迹,可以看出,代理人战略是美国频频实践但仍缺乏深入研究的现象。代理人战略是一种国家不直接出面,而是借助安全与外交领域的代理人实现间接制衡目标的战略手段。明确对手且制定相应策略是美国大战略的重要特征,当前美国政府认定的霸权威胁来源包括战略竞争对手、地区反美国家及恐怖主义等。基于战略目标的不同,美国针对上述三种威胁所采取的代理人战略的类型亦存在差异,分别是国家代理人战略、复合代理人战略以及次国家代理人战略。美国寻找的代理人一般与目标对象存在重大冲突或战略矛盾,代理人具有消耗与削弱对手的能力,代理人战略的实施路径包括威胁共识搭建及借力打力实践两个阶段。对于冷战后美国代理人战略的实践进行考察,有助于我们深入把握这种战略形式的逻辑延展及未来走向。  相似文献

Abstract

This article explores the relations to Africa and African decolonisation of three key figures in Brazilian critical geographies and development studies, Manuel Correia de Andrade (1922–2007), Josué de Castro (1908–1973) and Milton Santos (1926–2001). Based on an analysis of their works and unpublished archives, I argue the radical Third World perspectives these intellectuals expressed anticipated later critiques of development as a neocolonial device. Drawing upon current literature on decolonisation, international conferencing and anti-racist solidarity networks, I discuss these matters in relation to these authors’ interest in cultural diversity and internal colonialism. Crucially, they developed this sensitivity in the Brazilian Northeast, a region especially shaped by Afro–Brazilian and Indigenous cultural legacies. While supporting anti-imperialist nationalisms in the Third World, these Brazilian scholars fostered multilingual, internationalist and cosmopolitan activism and scholarship. This is revealed by the study of the transnational networks they developed during exile and the various persecutions that many of them suffered after the 1964 military coup. Finally, I argue these works can substantiate recent claims to ‘decolonise’ geography and development studies, on the condition that these fields of study take seriously their anti-imperial traditions and their ‘voices from the South’.  相似文献

Abstract

In this paper, we make a theoretical argument that the Third World be returned to its political origins to inspire an updated Third World Project (TWP), revived as a global movement for progressive, anti-imperialist forces, through the Fourth World movement, which highlights internal colonialism. Both the TWP and the United Nations recognise only nation states as full members. We examine how a Third World strategy that brings in the Fourth World, or indigenous, minority and/or stateless groups, can help oppressed groups gain more autonomy and rights through a transnational solidarity rooted in empathy. We trace the intellectual roots and history of the TWP and consider obstacles in bringing together the TWP and the Fourth World movement. A Fourth World strategy corrects the TWP’s implicit approval of an underlying imperialism, and the TWP provides the Fourth World movement a model to accomplish its goal of resisting uncritical modernity.  相似文献

ABSTRACT

The Critical Terrorism Studies (CTS) community has produced an important volume of work assessing and critiquing epistemological understandings of the War on (of) Terror. Largely missing from this body of work, however, is the experience of those who are directly impacted by the policies of this global phenomenon. By rethinking the War on Terror as an experience of war, I posit a wider understanding, by reassessing its temporal and spatial boundaries, but more significantly, the ways in which it is experienced. By providing a wider understanding of war and expanding our knowledge of its boundaries, I am able to show that those impacted by the policies of the War on Terror can claim to have been subject to an experience of war, even when that experience takes place outside of the war zone. This reflection, however, serves a larger purpose, which is to act as a call to the CTS community to centre the lived experiences of those impacted by the War on Terror in their work and decision-making when engaging with policy and policymakers. This represents a call for an ethical re-centring of CTS scholars to the violence of the War “of” Terror, by reminding us of the many ways in which harm can occur.  相似文献

Children born as a result of wartime sexual violence have not gained a place in the stories covered by the Colombian media. Based on an extensive content analysis (using the software MAXQDA 12) of newspaper articles published between 1990 and 2015, ethnographic content analysis, and drawing upon feminist critical discourse analysis, this paper explores how information about these children is presented as part of storylines that use the explanatory framework of sexual violence as a weapon of war. In those storylines, children emerge not as independent subjects but as part of social representations of female victims of wartime sexual violence and male perpetrators.  相似文献
