两种文化的互补和通识教育——关于科学文化和人文文化的若干思考

C．P．斯诺在关于“两种文化”的演讲中所批评的现象在今天并没有得到根本的改变。回顾20世纪人类社会两种主要的文化存在形式——科学文化和人文文化发展演变的轨迹,考察这两种文化在一些重大问题上出现不协调、甚至分离现象的各种复杂原因,说明这种现象的存在是人类自身认识和发展的一个误区,并导致人类在发展过程中付出了巨大的代价,而表现在教育上则为害尤烈：造成普遍的人文素质下滑、创新能力低下。从两种文化的相互冲突走向相互理解、相互参照,进而互补式地融合,尤其是在教育中强化和推行通识教育,是未来人类社会文化发展的总趋势,也是实践科学发展观的思想基础。

论明清文人笔下的柳敬亭

作为明末清初的民间说书艺人,柳敬亭以其酣畅淋漓、出神入化的表演技艺,取得了卓越成就,在中国俗文学史上享有突出地位。他亲历时代变迁,见证重大事件,富于情义品节,通过个人命运的起落跌宕,痛感身世之戚、家国之悲。诸多文士题赠诗文,又形成了一个颇为值得关注的文学现象,从他者的视阈,将柳敬亭视为文学表现对象,视为抒写广大文士复杂意绪的符号化人物。他们或赏其艺,或抒悲慨,或从道德层面加以鄙夷,或从权力意图予以利用,折射出清初遗民、学者、仕宦等不同角色人等的政治诉求、道德观念,更加彰显出柳敬亭的丰富文学意义。     

FARMER: A novel approach to file access correlation mining and evaluation reference model

File semantic has proven effective in optimizing large scale distributed file system. As a consequence of the elaborate and rich I/O interfaces between upper layer applications and file systems, file system can provide useful and insightful information about semantic. Hence, file semantic mining has become an increasingly important practice in both engineering and research community. Unfortunately, it is a challenge to exploit file semantic knowledge because a variety of factors could affect this information exploration process. Even worse, the challenges are exacerbated due to the intricate interdependency between these factors, and make it difficult to fully exploit the potentially important correlation among various semantic knowledges. This article proposes a file access correlation miming and evaluation reference (FARMER) model, where file is treated as a multivariate vector space, and each item within the vector corresponds a separate factor of the given file. The selection of factor depends on the application, examples of factors are file path, creator and executing program. If one particular factor occurs in both files, its value is non-zero. It is clear that the extent of inter-file relationships can be measured based on the likeness of their factor values in the semantic vectors. Benefit from this model, FARMER represents files as structured vectors of identifiers, and basic vector operations can be leveraged to quantify file correlation between two file vectors. FARMER model leverages linear regression model to estimate the strength of the relationship between file correlation and a set of influencing factors so that the “bad knowledge” can be filtered out. To demonstrate the ability of new FARMER model, FARMER is incorporated into a real large-scale object-based storage system as a case study to dynamically infer file correlations. In addition FARMER-enabled optimize service for metadata prefetching algorithm and object data layout algorithm is implemented. Experimental results show that is FARMER-enabled prefetching algorithm is shown to reduce the metadata operations latency by approximately 30%–40% when compared to a state-of-the-art metadata prefetching algorithm and a commonly used replacement policy.     

Searching high gray scale FPD scanning matrix based on PSO

With the increase of gray scale and flat panel display (FPD) size, subspace bitwise scanning strategy can be replaced traditional scanning method to cut down frame frequency. However, the direct searching strategy (DSS) becomes unfeasible to obtain corresponding high gray scale scanning matrix. Thus, particle swarm optimization (PSO) is introduced to accelerate searching for high gray scale weights scanning matrix (WSM) with its parallelism and global optimization feature. Finally a WSM of 256 gray scales is found out successfully with Matlab, which both gray linearity and scanning efficiency are satisfied.
