复平面上超越方程的数值解法及其应用

基于幅角原理和闭合曲线积分,结合MATLAB,提出了复平面上超越方程的两种数值解法,并编制了相应的程序。这两种方法都能将指定区域内的所有解求出,且无需选定初值。数值结果显示了这两种方法的优越性。     

生命活性分子与金属离子配合行为的极谱研究——Cu(II)二元配合物(I)

通过脉冲极谱法研究了以生命活性分子(Serine,Cysteine,Salicylic acid等)作为配体与Cu(II)形成多元配合物的极谱行为。在模拟生理条件μ=0.1(NaNO3)、T=310±0.2K下,发现电极过程为准可逆;通过对二元配合物稳定常数的测定表明,不同配体与金属离子配合的能力显著不同,配合物稳定性差异较大;同时还研究了各配合物的形态分布、引起稳定性差异的原因及影响因素。     

The Relationship Between Trait Affect and Job Attitudes in Library Employees

This research explores the relationship between employees’ disposition and several important job attitudes. Dispositional affect is a personality trait that describes people's emotional responses to situations. This study explored how affective disposition influences the job attitudes of work engagement, organizational commitment, and job satisfaction. Data were collected from a sample of librarians, and the results show that affective disposition strongly predicted the three job attitudes in the expected directions. The findings contribute to knowledge of the role of personality in the workplace and provide guidance for library managers on how best to facilitate positive job attitudes.     

Stabilization of Delayed Networks with Different Nodes

In this paper,the control of complex delayed networks with different nodes is proposed.Firstly,the stabilization of coupled networks with time delay is investigated.By constructing a Lyapunov function,a linear feedback controller design procedure for the networks is converted to the problem of solving a set of linear matrix inequalities.Then the results are extended to networks with both delayed dynamical nodes and delayed couplings.It is shown that the stabilization of complex networks is determined by the dynamics of each uncoupled node,coupling matrix and feedback gain matrix of networks.Two examples are simulated.In the first example,a network with 10 nodes consisting of Lorenz systems and systems proposed by Zhang in 2009 is given.It is found that the network states are divergent without control,and convergent under designed linear feedback controllers.In the second example,a larger network with 100 nodes consisting of delayed Chen systems and delayed Lorenz systems is given.The proposed method is also effective for large scale networks.

Environmental Disposition Factors as Perceived by German, American and Indian

Environment is a broad concept encompassing the whole range of diverse surrounding in which man perceive, experience and react to events and changes. The present investigation has been designed to study the environmental disposition factors as perceived by German, American and Indian. A group of 392 subjects were selected in this investigation. English, German and Bengali version of Environmental Response Inventory were administered to them. All the three groups have favourable attitude towards pastoralism, which means preservation of natural resources. Besides this, they also express variety of opinion in connection with urbanism, environmental adaptation, need privacy and antiquarianism.     

解读体育图片报道的民族情结——以《中国体育报》6届夏季奥运会图片报道为例

主要采用内容分析法对《中国体育报》1984-2004年6届奥运会的图片报道进行统计分析，从社会学的角度解读其中所蕴涵的民族情结，研究认为，图片报道在民族情结的传播中发挥着非常重要的功能，是民族情感的外化表现。20年来，《中国体育报》的图片报道展现以我为主的特色，民族情结具体表现为展示中华民族的崛起，体现祖国的强大；渴望祖国的统一，表达民族复兴的“中国情结”；渴望胜利，民族情感维系于“金牌情结”；宣扬英雄主义和牺牲精神；宣扬集体主义和群体观念。总体而言，《中国体育报》图片报道以理性民族情结为主导，只有个别图片报道呈现主观性和情绪化倾向。

基于复杂网络视角下中国体育产业结构特征研究

以2015年中国投入产出表为基础,切割了体育产业投入产出基本数据,将体育产业内部构成之间的非线性关系置于复杂网络系统,从“整体”“单点”“亚结构”3个层次刻画了体育产业结构的复杂性特征。研究表明:1)在研究期间,中国体育产业结构具有小世界网络特征,体育产业内部环形网络经济已经形成,但整体产业部门间联系不紧密,依赖于实物性的单向支持,影响了体育产业结构的溢出效益;2)不同产业部门在结构网中存在不同位置与角色,其中,实物性产业部门对于其他产业部门向前带动效果显著,而体育产品流通与经济技术交叉融合部门对其他产业部门向后支撑效果显著。体育用品及相关产品制造业有较强的辐射力与控制力,对部门间体育经济活动集散和中转作用较强,具备主导其他产业的实力。体育竞赛表演活动和体育场馆服务业与细分产业部门形成了一定的关联关系,在体育产业结构网络中具有一定的中介作用,是体育产业结构优化的关键部门;3)体育产业网络结构中存在“结构对等”的集聚子群,可划分为四大“模块”。模块之间互动关系呈现较为复杂的嵌套式产业链,提出“自反性”板块的特征。
