NaCl胁迫对不同番茄品种幼苗及果实的影响

研究了NaCl胁迫对5个不同番茄品种的幼苗生长、果实可溶性糖含量及产量的影响.结果表明,盐胁迫抑制了番茄幼苗植株的生长,降低了幼苗的单株鲜重,减少了果实产量,但可以提高果实可溶性糖含量.同一盐胁迫条件下,不同番茄品种性状存在显著差异.

走向“精神性”教师的教师哲学——评奈吉尔·塔布斯的《教师哲学》

奈吉尔·塔布斯在《教师哲学》中以黑格尔的精神哲学和主奴关系辩证法为理论基础建构教师意识发展史。作为主人的教师具有独立性与权威性,教育实践的特点是控制,为教师意识发展的正题;作为仆人的教师具有依赖性,教育实践的特点是"解放"与"解构",为教师意识发展的反题";精神性"教师兼具主人和仆人意识,其精神具有同一性和自由性,是教师意识发展的最高境界。     

Hopf拟群上扭曲冲积

为了研究平行球面s7的代数结构,引进了Hopf拟群上的拟模和双拟模代数的概念,由于这些概念的公理中模缺少结合性的条件,通过增加对极的条件来弥补结合性的条件.并通过双拟模代数构造了扭曲冲积的概念,事实上这种扭曲冲积是Hopf代数上扭曲冲积的推广,并且证明了扭曲冲积与张量余积成为Hopf拟群的充要条件为当且仅当下列条件(h...

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.     

论言语交际中语境的选择和操控

语境的生成是一个动态的过程,语境生成的动态性不仅体现在言语交际中参与者对相关语境要素的选择和调控上,也体现在言语交际活动之后双方对不同表意框架的选择上.该文通过对一起由手机短信所引发的争议的分析表明:言语交际的参与者为了达到特定的目的,可以对不同语境要素和表意框架进行选择,通过对语境的操控来影响释话人的行为.
