基于可视化交互的国动指挥所设计

国防动员的指挥控制中大量的信息数据(如部队需求、地方资源)和错综复杂的多方关系,使得指挥员难以在短时间内从浩如烟海的信息中提取有用的决策信息和作出快速准确地指挥协调。为此,着眼未来指挥所的发展趋势,提出基于可视化交互的国动指挥所设计方法:通过分析国动指挥任务的关键路径,提取重要的决策信息,利用可视化交互技术,实现对国动任务的信息化指挥控制。以某部演习的国防动员指挥为例,验证了方法的可行性和有效性。     

地下储油复杂组合空间油气扩散蔓延三维数值模拟

针对地下储油复杂组合空间,采用大涡模拟的方法构建了油气扩散蔓延三维数值模拟模型,完成了油气扩散蔓延区域的空间离散和三维数值模拟求解优化,并进行了数值计算与分析。结果表明,在地下复杂组合受限空间油料泄漏后,罐室内的油气填充顺序为由边缘到出口、由底部到上部,油气不能达到100%的充满状态,罐室拱形顶部油气体积分数低于其爆炸下限的20%;罐室内油气的产生和蔓延十分迅速,从泄漏至到达罐室口仅需10 s,进入坑道仅需1 min;油气在流出罐室进入坑道后,具有迅速向四周扩散蔓延,流向一切可能注入的空间的特性。研究结果为地下储油工程的施工建设、安全管理、危险源监控等提供了有益参考。     

“Respect” as a personal attribute in the British Army

This article describes the results of research into the social phenomenon of “respect” as framed by junior members of the British Army, as part of a wider study into the Values and Standards of the British Army. This research was interview based, using qualitative analysis software to detect, manage, and draw conclusions from the qualitative data recorded in those interviews. The data indicated that the primary situation in which “respect” was visualised by the participants was the unit context, and that it comprised a combination of three different strands: respect for rank or “hierarchical respect,” “professional respect” for a person's military competence, and “personal respect” for an individual's character, personal behaviour, and attributes. The overall respect that an individual is given arises from the combination of these three areas. “Respect” as a concept was, in the soldiers’ characterisation, something that had to be earned (except for the “given” represented by rank) and was not stable: a person's fund of respect could go up or down in social value. Respect was also linked to trust: the more respect a person had, the more they could be trusted. Although the unit context was the primary one for discussing their framing of the concept of respect, many of the participants reported a wider dimension in which every human being deserves a basic level of respect simply for being human, and this level could not be forfeited.     

A trajectory for homeland ballistic missile defense

The Ground-based Midcourse Defense system is intended to protect the US homeland against limited attacks from intermediate- and long-range ballistic missiles. It has succeeded in intercepting target missiles and can engage a threat launched from North Korea or the Middle East, targeting any point in the USA. Nevertheless, high-profile struggles and program changes related to homeland ballistic missile defense (BMD) continue to make headlines. The most significant struggle has been a string of three straight intercept test failures over five years, followed by the recent successful intercept test in June 2014. This article first briefly reviews the current threats of concern. It then examines homeland BMD policy objectives, followed by the current major technical issues in supporting these objectives and, then, the likelihood of negating a warhead. Finally, it highlights major considerations that should be part of the trajectory the US government takes moving forward.     

From rivals to partners: AirSea Battle and the US air force–navy relationship

AirSea Battle (ASB) has generated significant publicity, controversy, and debate among scholars, analysts, commentators, and observers of US defense strategy. However, a research gap exists concerning formal analysis of the impact of the operational concept on the relationship between the US Air Force (USAF) and the US Navy (USN). The impact of the ASB operational concept on the USAF–USN relationship is examined across the issue areas of strategy, budgets, weapons procurement, and training. These four issue areas represent important areas of historical conflict and competition between the Air Force and Navy. The conclusion is that ASB is ushering in a new era of Air Force–Navy partnership that advances the inter-service dynamic from “jointness” toward integration. The emergent USAF–USN partnership therefore represents a significant development in US defense politics and defense strategy.     

Epidemics,national security,and US immigration policy

What are relationships between epidemics, national security, and US immigration policy? This question is important because it sheds light on transnational or nontraditional security areas, American immigration policy, and a pressing issue for US leaders who have recently faced epidemics such as the West Africa Ebola outbreak that began in 2013. This article answers it and lays ground in the area by reviewing epidemics in world history, using International Relations and Security Studies works to specify dangers of contagions for states, and identifying three general immigration measures that American leaders have utilized from the seventeenth century to the present day to protect against contagions, which are (1) policies restricting entrance of foreigners thought to carry specified diseases, (2) the isolation or quarantining of immigrants with contagious disease, and (3) delegating the President with authority to stop immigration in the event of an epidemic abroad. This study has implications for research and contemporary US immigration policy.     

Women combatants and the liberation movements in South Africa

This article examines women's role as combatants in national liberation forces in South Africa. Three categories – guerrilla girls, combative mothers and the in-betweeners – are introduced to underscore the varied ways in which women have participated in combat within the national liberation movements. Factors such as age and one's ability to leave the country affected whether women could participate in combat as ‘guerrilla girls’ or if it limited them to fighting apartheid violence from home, or if there were women who can be defined as having fallen somewhere in between these categories. These categories are used to theorise women's combat roles in the anti-apartheid struggle, thus broadening and challenging the dominant notions of combat that often hide women's contributions in war. In this regard, different periods of struggle, physical location, as well as age, determined the methods of activism available to men and women.     

Sexual and gender-based violence in the Democratic Republic of Congo

Commitment by the government of the Democratic Republic of Congo to addressing sexual and gender-based violence (SGBV) in the country is reflected in a number of international commitments and national strategies. This article traces the (slow) progress in addressing some of the most important issues relating to SGBV to which the government has committed itself. It argues that unless the underlying gender norms and unequal power relations that form the basis of gender violence, discrimination and inequality in Congolese society are addressed, SGBV will persist.     

Women,peace and security in Africa

This article highlights and critiques the underlying conceptualisations and assumptions of the women, peace and security (WPS) agenda that emerged with the adoption of United Nations Security Council Resolution 1325 in 2000. The main argument is that we need to rethink the WPS agenda to produce more holistic and groundbreaking responses for the types of challenges encountered, i.e., that gender inequality and insecurity are deep rooted and multi-layered, and thus negate mechanistic responses that do not deal with cultural and structural issues. It specifically focuses on gender and peace-making and gender and peacekeeping to point to the pitfalls in the current conceptions and practices in this arena.
