中小企业融资困难经济解释新视角

中小企业融资困难的原因可以运用新古典经济理论来解释.新古典经济理论通过建立银行与中小企业之间的第二类价格歧视模型和第三类价格歧视模型,发现了即使不考虑道德风险和逆向选择等信息不对称问题,中小企业仍存在融资障碍,这就从不同于一般信息经济学的一个新的视角解释了中小企业信贷约束问题.     

Multi-period model of portfolio investment and adjustment based on hybrid genetic algorithm

This paper proposes a multi-period portfolio investment model with class constraints, transaction cost, and indivisible securities. When an investor joins the securities market for the first time, he should decide on portfolio investment based on the practical conditions of securities market. In addition, investors should adjust the portfolio according to market changes, changing or not changing the category of risky securities. Markowitz mean-variance approach is applied to the multi-period portfolio selection problems. Because the sub-models are optimal mixed integer program, whose objective function is not unimodal and feasible set is with a particular structure, traditional optimization method usually fails to find a globally optimal solution. So this paper employs the hybrid genetic algorithm to solve the problem. Investment policies that accord with finance market and are easy to operate for investors are put forward with an illustration of application.     

研究生德育工作制约因素分析及建议

研究生群体是一个特殊群体,德育工作存在许多相关的制约因素,既有研究生群体自身构成多样化、生理和心理特征等内在因素,也有来自于德育工作模式不够完善的外在因素。只有明确相关制约因素,才能加强研究生德育工作的针对性,从而提高德育工作的有效性。     

论“语用预设”对广告语言语力的制约与促进

文章从＂语用预设＂的合适性、共知性、取消性和透射性等特征入手,分析忽视语用预设存在,忽视其特征而制约广告语言的语力,形成语用失误的原因和该原理的积极运用产生的促进作用,以有效帮助广告商提高语用能力和广告水平,避免广告语言的语用失误。     

实施效果与制约因素：南京国民政府1930年婚姻法考察

司法实践中之法律与文本状态下的法律往往呈现某种或大或小的差距。民国时期是我国移植西式法律之立法高峰期。静态中之文本易移植,而照搬建立在西式工业文明之上的法律却难在我国生根发芽。原因在于制约法律实施效果的因素颇多,如：法律文本与现实的脱离、“息讼”观念的影响、司法无力,等等。     

中国英语学习者叙述性语篇理解中的预期推理研究

本文以不同英语水平的中国英语学习者为研究对象, 采用命名实验和关键句阅读实验的在线研究方法, 着重考察了语篇因果制约度和读者的二语水平对语篇理解中预期推理的激活和编码的影响。 研究结果表明：1)在二语语篇阅读过程中, 语篇的因果制约度影响预期推理的即时激活, 当语篇因果制约度高时, 读者易做出预期推理;2) 在二语语篇阅读过程中, 预期推理概念的激活受读者语言水平的影响, 高级英语水平 读者能够在较低水平上即时激活预期推理概念, 而中级语言水平读者预期推理概念不能即时激活;3) 对于高 级英语水平读者 ,预期推理能够在激活后保存于读者工作记忆并编码于语篇短时记忆表征, 但这种编码只是 一种部分编码 。     

关键制约因子下绿色经济评价模型及实证研究

通过将绿色经济评价指标体系的五个不同方面作为约束条件引入模型,可客观、有效地得出影响各评价对象绿色经济发展状况的关键因子。主要做法:一是利用离差最大化优化模型对各评价指标赋权,保证所求权重的客观性与合理性。二是将5个不同层面分别作为制约条件引入评价模型得到模型最优解。三是分别对有、无制约条件下的各评价对象的排名波动情况进行分析比较,确定各盟市绿色经济的发展差异以及影响其发展优劣的关键要素。实证结果表明,环境保护的相关方面对各盟市绿色经济发展影响最大,资源承载力及人的全面发展方面次之。     

压抑机制下的必然选择——解读简爱的出走

《简爱》是一本带有自传性质的小说。女主人公简爱是一个勇敢、坚强,具有强烈反抗意识的独立女性,但在作品中这样一个刚强的女性却频频选择出走。本文欲运用弗洛伊德和弗洛姆的精神分析理论,通过对压抑机制的探析和几组象征着压抑机制的具象的分析,解读简爱选择出走的原因。     

基于多层约束的叶轮数控进刀精度控制算法

随着工业生产要求的不断增加,对叶轮的精度要求越来越高,这就给数控生产设备的控制精度提出了更高的要求,为了解决这一问题,提出一种基于多层约束的叶轮数控进刀精度控制算法,通过建立数控进刀控制模型,充分考虑进刀中叶轮的复杂情况。运用多层进刀条件约束模型方法,控制进刀精度,最大程度的满足精度要求,后期的计算机仿真实验证明,这种控制算法能够很好的完成叶轮数控进刀的多个约束条件的最优解计算,控制精度有了明显的提高。     

Programming Time as a Function of Movement Constraint

Abstract

Although the benefits of exercise are well documented, an international problem of physical inactivity exists. More research, especially theory based, has been recommended. One promising approach for studying exercise behavior is that proposed in the Transtheoretical Model (TTM) of behavior change. This model, however, has received minimal cross-cultural attention and, relative to the current study, measurement instruments have only recently been translated into the Finnish language. The purpose of this study was to assess American and Finnish college students' exercise behaviors on the basis of TTM. Participants were American (n = 169) and Finnish (n = 168) college students who completed language-specific measures of exercise behavior, stage of change, processes of change, decisional balance, self-efficacy, and temptation. The only cultural difference observed was that the American participants rated themselves higher on barrier self-efficacy relative to the Finnish participants. Regardless of nationality or gender, participants classified by their stage of change differed on all the core constructs assessed. These results generally support the utility of TTM for understanding American and Finnish college students' exercise behavior.
