人才吸引力因素与政策工具契合关系研究以河北省为例

人才是第一资源,人才引进培养是经济社会发展的一个关键,近年来我国各地纷纷出台吸引人才的重磅政策.为探求人才政策工具对人才的吸引力情况,在构建人才吸引力因素理论模型基础上,通过对178位人才问卷调查获得人才吸引力关键因素,对河北省163份人才政策文本进行数据挖掘,分析政策工具与人才吸引力因素的契合关系.研究得出创新氛围、人才培训培养、人才激励评价、创新创业支持、人才服务和薪资待遇等方面契合度高,政策效果较佳;工作场所仪器设备条件、配偶子女安置和住房补贴的契合关系为政策不足,应加大政策制定;人才载体和医疗社会保障的契合关系为政策冗余,需加强政策实施.     

大学英语教学中中国传统文化渗透路径探究

文化与语言有着密切的联系，一定的文化背景知识有助于促进语言应用能力的提高。大学英语教学的同时也应该是对文化的传授，英语教学不仅是语言知识的教授，更应该是文化知识的传播。从多模态视角出发，探究中国传统文化导入大学英语教学的必要性及途径，有助于提高当代大学生的英语识读能力及文化传播的能力。     

上海黄浦江两支流河流甲烷含量研究

甲烷是一种重要的温室气体,虽然目前大气中含量远小于二氧化碳,但排放增长率却大于后者.研究区域为上海市黄浦江支流苏州河和淀浦河,通过实验数据对比城郊春夏的甲烷排放的差异,探讨甲烷产生的机制及其与环境因子的关系,这将有助于研究河流甲烷排放对于环境变化的影响.研究结果认为河流甲烷主要来源于水中沉积物,其产生与水质、温度等因素相关;同时甲烷摩尔浓度与硝酸根离子质量体积比存在负相关性,与铵根离子质量体积比和有机碳质量分数存在正相关性.     

Finding any given 2‐factor in sparse pseudorandom graphs efficiently

Given an $n$‐vertex pseudorandom graph $G$ and an $n$‐vertex graph $H$ with maximum degree at most two, we wish to find a copy of $H$ in $G$, that is, an embedding $\phi :V\left(H\right)\to V\left(G\right)$ so that $\phi \left(u\right)\phi \left(v\right)\in E\left(G\right)$ for all $uv\in E\left(H\right)$. Particular instances of this problem include finding a triangle‐factor and finding a Hamilton cycle in $G$. Here, we provide a deterministic polynomial time algorithm that finds a given $H$ in any suitably pseudorandom graph $G$. The pseudorandom graphs we consider are $\left(p,\lambda \right)$‐bijumbled graphs of minimum degree which is a constant proportion of the average degree, that is, $\mathrm{\Omega }\left(pn\right)$. A $\left(p,\lambda \right)$‐bijumbled graph is characterised through the discrepancy property: $|e\left(A,B\right)?p|A||B||<\lambda \sqrt{|A||B|}$ for any two sets of vertices $A$ and $B$. Our condition $\lambda =O(p^{2}n/\log n)$ on bijumbledness is within a log factor from being tight and provides a positive answer to a recent question of Nenadov. We combine novel variants of the absorption‐reservoir method, a powerful tool from extremal graph theory and random graphs. Our approach builds on our previous work, incorporating the work of Nenadov, together with additional ideas and simplifications.     

An Improved Composite Multiscale Fuzzy Entropy for Feature Extraction of MI-EEG

Motor Imagery Electroencephalography (MI-EEG) has shown good prospects in neurorehabilitation, and the entropy-based nonlinear dynamic methods have been successfully applied to feature extraction of MI-EEG. Especially based on Multiscale Fuzzy Entropy (MFE), the fuzzy entropies of the τ coarse-grained sequences in τ scale are calculated and averaged to develop the Composite MFE (CMFE) with more feature information. However, the coarse-grained process fails to match the nonstationary characteristic of MI-EEG by a mean filtering algorithm. In this paper, CMFE is improved by assigning the different weight factors to the different sample points in the coarse-grained process, i.e., using the weighted mean filters instead of the original mean filters, which is conductive to signal filtering and feature extraction, and the resulting personalized Weighted CMFE (WCMFE) is more suitable to represent the nonstationary MI-EEG for different subjects. All the WCMFEs of multi-channel MI-EEG are fused in serial to construct the feature vector, which is evaluated by a back-propagation neural network. Based on a public dataset, extensive experiments are conducted, yielding a relatively higher classification accuracy by WCMFE, and the statistical significance is examined by two-sample t-test. The results suggest that WCMFE is superior to the other entropy-based and traditional feature extraction methods.     

高校校园文化景观设计创意和表达

高校校园的文化景观不仅对其师生有潜移默化的教育作用,更会传达给师生归属感和认同感.以上海应用技术学院奉贤校区的"思贤庭"为例,在设计中结合地理位置、学科特色、功能定位、校园文化特色等,从场地原有的精神特性、历史文脉出发,演绎推导出校园文化景观的语境、符号等要素,形成了较有典型意义的校园文化景观表达模式.指出,文化景观创意的表达无需说教,可用"只言片语"的形式含蓄表达,重要的是营造出既符合功能需求又具有灵性的校园户外空间.     

军事用语语义泛化缘由探析

军事用语语义泛化的原因主要有两点:一是从语言系统外部来看:主要与语用环境的相似、言语修辞活动、言语交际中的心理因素等社会文化语用条件有关联;二是从语言系统内部来看,主要与语言的经济性原则密切相关。

他者的眼光与中国交际文化的模式

西方人普遍认为中国人的交际行为具有间接性和含义模糊的特点。这种化误读的根源在于西方人用他的眼光看待中国交际化，容易看到其显性化的一部分。阐释这些化现象时，西方人容易用自己交际化的标准对中国交际化进行重构，忽略中国交际化的隐性化，把中国交际化的多样性和复杂性简单化。     

从中西方文化冲突看文化对司法制度的影响

一个国家，一个民族在长期的历史发展中，形成了自己特定的文化传统，人们的思想观念，价值取向甚至法律制度都植根于其文化传统之中，本文从律师在社会生活中的作用，司法公正的价值取向，证人出庭作证制度，打官司与打“关系”等方面分析了文化传统对司法制度的影响。
