论普里什文哲理散文中的生态文学思想与猎人情结

普里什文哲理散文中所具有的预言式生态思想与环保理念备受当代“生态文学”理论家的青睐。但他热衷描写狩猎场景的猎人情结却又遭到新世纪中“生态伦理”理论的诟病。其实从文本的本体性观念来理解，普里什文的诗性自然情怀、生态观念与他的猎人情结并非只有冲突的一面，他所表达出的是人对大自然万物之本能与道义之间的尺度衡量，而这种衡量也可反观当代人与自然万物之间的关系的现状，实际上表达出一种更为深刻的天人关系的批判性。     

Risk Modeling of Interdependent Complex Systems of Systems: Theory and Practice

The emergence of the complexity characterizing our systems of systems (SoS) requires a reevaluation of the way we model, assess, manage, communicate, and analyze the risk thereto. Current models for risk analysis of emergent complex SoS are insufficient because too often they rely on the same risk functions and models used for single systems. These models commonly fail to incorporate the complexity derived from the networks of interdependencies and interconnectedness (I–I) characterizing SoS. There is a need to reevaluate currently practiced risk analysis to respond to this reality by examining, and thus comprehending, what makes emergent SoS complex. The key to evaluating the risk to SoS lies in understanding the genesis of characterizing I–I of systems manifested through shared states and other essential entities within and among the systems that constitute SoS. The term “essential entities” includes shared decisions, resources, functions, policies, decisionmakers, stakeholders, organizational setups, and others. This undertaking can be accomplished by building on state‐space theory, which is fundamental to systems engineering and process control. This article presents a theoretical and analytical framework for modeling the risk to SoS with two case studies performed with the MITRE Corporation and demonstrates the pivotal contributions made by shared states and other essential entities to modeling and analysis of the risk to complex SoS. A third case study highlights the multifarious representations of SoS, which require harmonizing the risk analysis process currently applied to single systems when applied to complex SoS.     

关于高校中层副职干部几个基本问题的思考

Real nonparametric regression using complex wavelets

Summary.  Wavelet shrinkage is an effective nonparametric regression technique, especially when the underlying curve has irregular features such as spikes or discontinuities. The basic idea is simple: take the discrete wavelet transform of data consisting of a signal corrupted by noise; shrink or remove the wavelet coefficients to remove the noise; then invert the discrete wavelet transform to form an estimate of the true underlying curve. Various researchers have proposed increasingly sophisticated methods of doing this by using real-valued wavelets. Complex-valued wavelets exist but are rarely used. We propose two new complex-valued wavelet shrinkage techniques: one based on multiwavelet style shrinkage and the other using Bayesian methods. Extensive simulations show that our methods almost always give significantly more accurate estimates than methods based on real-valued wavelets. Further, our multiwavelet style shrinkage method is both simpler and dramatically faster than its competitors. To understand the excellent performance of this method we present a new risk bound on its hard thresholded coefficients.

现代性的困惑、焦虑与质疑 --三维视角中的中国现代文学史论

20世纪中国文学的非现代性特质,是一个不可忽视的历史事实。文学运动规律的混乱无序性以及文学独立品格的人为淡化,使其完全背离了它所刻意追求的西方现代文学模式。不同时期所宣扬的西方人文精神和价值观念体系,都明显流露出儒家入世哲学的浓重色彩。一部中国现代文学史,从某种意义上来说,就是中国文学传统的一种现代汉语包装形式,它无法根绝自己独特的历史遗传性,同时也难以融入西方现代文学的话语系统。所以,中国现代作家那苍凉而悲壮的启蒙呐喊,集中体现着他们对于“现代性”的困惑与焦虑。
