高师生社会支持与信息焦虑的关系研究

目的:研究高师生社会支持与信息焦虑的相关关系,旨在找出能够用社会支持改善信息焦虑状况的办法。方法:采用信息焦虑量表和领悟社会支持量表238名高师生进行测查。结果:1高师生社会支持的整体水平有极其显著性差异(F=6.083,P0.05)。2信息搜索与选择焦虑维度上存在显著的性别差异(T=4.218,P0.05)。在信息搜索和选择焦虑、信息饥渴焦虑上存在显著的年级差异(F=3.231,P0.05)。3湖北师范学院高师生信息焦虑和社会支持各因子间呈显著负相关(R=-0.153,P0.05)。通过回归分析,社会支持对信息焦虑程度具有预测作用(F=4.617,P0.01)。结论:通过增加社会支持来缓解高师生的信息焦虑。     

Choosing arrival process models for service systems: Tests of a nonhomogeneous Poisson process

Service systems such as call centers and hospital emergency rooms typically have strongly time‐varying arrival rates. Thus, a nonhomogeneous Poisson process (NHPP) is a natural model for the arrival process in a queueing model for performance analysis. Nevertheless, it is important to perform statistical tests with service system data to confirm that an NHPP is actually appropriate, as emphasized by Brown et al. [8]. They suggested a specific statistical test based on the Kolmogorov–Smirnov (KS) statistic after exploiting the conditional‐uniform (CU) property to transform the NHPP into a sequence of i.i.d. random variables uniformly distributed on [0,1] and then performing a logarithmic transformation of the data. We investigate why it is important to perform the final data transformation and consider what form it should take. We conduct extensive simulation experiments to study the power of these alternative statistical tests. We conclude that the general approach of Brown et al. [8] is excellent, but that an alternative data transformation proposed by Lewis [22], drawing upon Durbin [10], produces a test of an NHPP test with consistently greater power. We also conclude that the KS test after the CU transformation, without any additional data transformation, tends to be best to test against alternative hypotheses that primarily differ from an NHPP only through stochastic and time dependence. © 2014 Wiley Periodicals, Inc.

Counterinsurgency American style: Considering David Petraeus and twenty-first century irregular war

This article examines the complex legacy of David Petraeus who was a key figure in the emergence of the US military shift towards counterinsurgency doctrine in the years after 2006. Although Petraeus has been perceived by critics as a publicity seeker, he can be credited with laying the foundations for a more serious commitment to COIN involving in particular in integrating conventional and Special Forces in arenas like village stability operations. The article looks a Petraeus's role in both Iraq and Afghanistan: it concludes that, in the case of Afghanistan, it is too early to assess whether counterinsurgency has had a decisive impact of the outcome of the war against the Taliban.
