EU armed forces and social media: convergence or divergence?

This article explores how armed forces in EU member states work with and view social media in national and international settings, and what the patterns of convergence/divergence are on these issues. To that end, a questionnaire targeted at EU armed forces was constructed. An index of qualitative variation was calculated to explore the relative convergence among respondents (n = 25) on issues of risks and opportunities with using social media nationally and internationally. Consistent with previous research on European armed forces, we found higher levels of divergence than convergence. Contrary to our expectations that similar challenges, joint international standards, and membership in international organizations would foster convergence with regard to social media use in areas of deployment, we found that convergence appeared foremost pertaining to the domestic level. Policy divergence was strongest in areas of deployment.     

新条件下Fourier级数L~p可积性的研究

小样本多元数据分析和数据压缩、编码等是装备维修与故障分析中的常用技术,这些技术的理论研究常常归结到用函数的Fourier系数刻画可积函数类问题。研究了正弦级数和余弦级数属于Lp函数类的条件,建立了在NBVS假设条件下的判别准则,推广了已有结果。
