可转债市场与股票市场间的溢出效应研究

将利率作为外生变量,运用VAR-（BV）EGARCH模型对可转债市场与股票市场之间的溢出效应进行研究。研究结果表明:在收益溢出方面,只存在股票市场对可转债市场的溢出效应。在波动溢出方面,存在可转债市场与股票市场之间的双向溢出效应;并且存在利率市场向股票市场的单向波动溢出效应。从非对称溢出效应来看,存在股票市场对可转债市场的波动溢出的非对称性,由此可以看出,股票市场仍然是出于绝对支配地位的金融市场。     

探究生牛乳中游离氨基酸的测定方法—分光光度法

本试验是在加热条件下,氨基酸与茚三酮反应生成紫色物质,该物质颜色深浅与氨基酸含量成正比,用分光光度法可计算出样品中氨基酸含量。     

中小企业应用B2B电子商务绩效分析

中小企业的规模小、资金少等特点,决定了使用第三方B2B平台开展电子商务是其最佳选择,但由于很多中小企业对电子商务认识不足,导致电子商务绩效并不理想。本文通过理论和案例分析,分析了中小企业使用B2B的现状和影响因素,试图找出中小企业电子商务绩效不理想的主要原因,并提出一系列对策。     

从《吕氏春秋》看《乐记》部分篇章的成书年代及其佚篇

《吕氏春秋》仲夏、季夏二纪中的八篇文章以论乐为主,通过考察这八篇文章中与《礼记·乐记》相同的内容,可知《乐记》中的《乐本》、《乐言》、《乐象》等篇在《吕氏春秋》撰写前已经基本成书。而结合其他传世典籍中的相关记载,可以推测《吕氏春秋》仲夏、季夏二纪可能还保存了《乐记》十二佚篇中的《乐作》、《说律》与《意（音）始》篇。

基于正交试验的间歇传动链动力学仿真研究

以间歇传动链为研究对象,建立了该系统的虚拟样机。运用正交法设计试验,选择输入轴转速、导轨材料阻尼系数、链条和导轨之间的库仑动摩擦系数、预紧弹簧刚度和集中质量共5个因素作为试验参数,以链条附件加速度值作为振动指标,进行了间歇传动链的动力学仿真研究。     

有杆抽油系统诊断方法研究与应用

以有杆抽油系统动力学行为分析为基础,将基础理论研究和应用技术有机地结合起来,建立了考虑悬挂系统弹性的直井和定向井有杆抽油系统诊断模型,研究了基于B/S（Brower/Server）模式的有杆抽油系统故障诊断方法,利用Internet技术和Web技术开发了相应的软件系统, 通过浏览器即可实现对有杆抽油系统快速、准确的故障诊断,并给出了诊断算例,诊断结果验证了该系统的有效性。基于B/S模式的有杆抽油系统故障诊断对避免井下作业的盲目性,提高系统效率,降低采油成本,实现油田企业信息化和提高油井的科学管理水平具有重要意义。     

Le marché comme rencontre d’activités de régulation : initiatives et innovations dans l’approvisionnement bio et local de la restauration collective

How to apply Jean-Daniel Reynaud's theory of social regulation to market relations? When applied to the results drawn from fieldwork on the supplying of organic and local produce to catering businesses serving public institutions in France, this grid of analysis shows that organizing this supply chain involves many activities of regulation. An explanation is provided about how hard existing regulations make it to search for local produce. Two contrasting cases show the degree to which the parties involved can skirt around existing regulations and also, use certain regulations to construct new ones. The innovative regulations that enter into application are qualified as being “joint”, since they stem from the efforts of the parties in catering and in agriculture to agree about how to organize transactions, which had previously been done through the work of market middlemen. In that case, instead of reasoning in terms of a pre-existing supply and demand, we have to understand how supply and demand gradually take shape through the process of working out regulations.     

La dynamique de la vocation : les évolutions de la rationalisation de l’engagement au travail des danseurs de ballet

The commitment to one's work, with body and soul involvement is a key issue in the study of vocation-driven occupations. In such callings, the aspirations that are socially constructed and experienced as vocations have been shown to provide meaning and direction to one's commitment. However, this study of Paris Opera ballet dancers shows that realizing one's aspirations are impossible to achieve does not necessarily result in quitting, nor retraining. Changes in the way dancers relate to their work are studied using sequential analysis, to examine which social factors may explain how this involvement's meaning is maintained. The analysis identifies some processes of vocation recomposition. Thus revealing, behind the professional careers, the “moral careers” of the vocation.     

Anticiper ou temporiser : injonctions environnementales et recompositions des identités professionnelles en céréaliculture

Questions about the modernization of farming, given its environmental impact, are leading French farmers to rework their occupational identities. This is studied by comparing cereal growers who practice “integrated protection” — a form of agriculture that saves on input — with their “conventional” colleagues. Given the high degree of uncertainty about the standards that will be imposed, cereal farmers have adopted positions that contrast with regard to: the future (anticipating vs. stalling for time), “professional excellence” (whether or not to accept lower yields) and risks (whether to adopt strategies turned toward vigilance or toward insurance). The diffusion of innovative farming practices is limited owing to their lack of legitimacy, which leads farmers to explore the possibilities for obtaining legitimation from outside the profession.
