日-地(月)系拉格朗日L1点及晕(Halo)轨道应用

日-地(月)系统拉格朗日L1点及L1点附近的晕(Halo)轨道在"夸父"工程中有重要的应用价值,可用于对太阳实施持续观测.利用数值分析方法,找到了日-地(月)-探测器三者构成的圆限制性三体问题中L1点附近的周期晕(Halo)轨道,分析了轨道的特性.研究结果对"夸父"工程中的目标轨道设计有一定的参考价值.     

军内行政执法主体研究

军内行政执法主体是指依法享有军内行政执法权的组织。但是，在理论上如何界定军内行政执法主体的范围？军内行政执法主体之间的相互关系如何界定？军内行政执法主体之间的职权在宏观上如何划分？这便是本文所要探讨的问题。     

三维介质体的时域散射分析

用时间递推(marching-on in-time,MOT)方法求解了电磁场时域耦合积分方程,计算了均匀介质体的表面等效电流和表面等效磁流,得到时域散射远场并给出了详细推导过程。举例比较了将时域散射用Fourier变化后在频域的RCS和频域直接求得的RCS,以说明该算法的正确性。     

对加强公安边防群众工作的思考

加强公安边防群众工作对维护沿边沿海地区社会稳定,推进新时期公安边防工作具有重要意义。从主、客观两方面分析了当前公安边防群众工作中存在的问题,提出公安边防群众工作要坚持为现实斗争服务、为打造服务型机关服务的原则,消除四个误区,提高专业化、信息化和社会化水平,加强保障机制、考核评估机制、奖惩激励机制和监督制约机制建设,推动公安边防群众工作深入开展。     

旋转椭球体的瞬态电磁目标特性研究

本文针对旋转体金属目标,提出了改进的时域递推法,以计算其电磁脉冲响应特性,它将面上的二线问题降为一线问题,减少了计算量,以便于计算大尺寸目标。同时,用该方法计算了不同脉冲宽度激励下球的反射波形和不同长度棉球的反射波形,并讨论了它们的特性。     

The objectified female body and the Boko Haram insurgency in northeast Nigeria: Insights from IDP camps in Abuja

ABSTRACT

Scholars have written extensively on the multiple roles and functions of female bodies. Their depictions in areas such as reproduction, sex, oppression and empowerment, peace and protest, weakness and strength, among others, have been examined through the ages. In addition, the objectification of female bodies in terms of rape, mutilation, forced pregnancy, physical assaults and forced labour within the domestic sphere and the society at large have been articulated. One notable gap in the literature in this regard has to do with a focus on the emerging trends in which armed groups are exploitatively engaging female bodies in their activities. This study, therefore, relies on interviews with Internally Displaced Persons (IDP) in Durumi and Lugbe camps, Abuja, two officials of Non-Governmental Organisations (NGOs) working with displaced persons in the selected camps, development partners, documents, and published sources to examine the diverse ways in which the Boko Haram group has objectified the female body (as objects of sexual gratification, procreation, propaganda and profile enhancement, care-giving and gatekeeping as well as weapons of suicide bombing) and the socio-cultural factors fuelling their actions toward females in the northeastern part of Nigeria.
