边际效用递减规律的再发现

本文的成果主要体现在两个方面:第一,将时间维度导入效用函数,实现了对边际效用递减规律认识的一次真正的飞跃;第二,将需求在需求要素的层次上进行分解,使边际效用递减规律有了更为准确和牢靠的基础。在这两个成果的基础上,对效用的可测量性、商品的同质性假说等问题进生了前瞻性的探讨。     

保密通信中的分形调制技术

分形调制在保密通信中具有广阔的应用前景。介绍了分形调制的原理,讨论了其在多速率分集、抗1/f噪声、抗频率选择性衰落、适用于信道条件复杂的MIMO通信系统等方面的特点。由于作为密钥的小波基任意多,且可根据信道情况在不同的小波基之间跳变,故分形调制具有极强的保密性和抗破译能力。     

一种基于ADV202的视频压缩系统设计

为了解决传统模拟视频系统带宽太宽、易受干扰的问题,设计了一种满足无线信道传输视频信号的特殊要求的视频压缩子系统.该系统的算法采用基于小波变换的M-JPEG2000算法,没有帧间压缩,非常适合在实时性要求很高的情况下压缩数字视频,并且没有JPEG的方块效应,且具有很强的灵活性,可根据不同的需要来通过软件配置来满足其要求.     

基于分形理论的广西城市体系空间结构研究

城市是人口和经济的聚集地,城市体系空间结构具有分形几何特征。将分形理论与中心地理论相结合,通过城市体系的关联维数模型计算出广西城市体系空间结构的分维值,发现广西城市体系的空间分布是具有分形特征,城市体系自组织演化在空间结构方面具有优化趋势,可以强化中心、极化南宁核心地位,重点扶持桂林、柳州、北海三个副中心建设,构建"一枢纽、二港口、三通道、四辐射"大通道体系和点轴面相结合发展的广西城市体系空间结构。     

The Ethical Dimensions of Decision Processes of Employees

The influence of stakeholders, organisational commitment, personal values, goals of the organisation and socio-demographic characteristics of individuals on the ethical dimension of behavioural intentions of employees in various organisations are investigated. The research results show that employees working for the public sector or in educational institutions take more ethical aspects into account than employees working in the "private" sector. The influence of stakeholders and organisational commitment do not significantly affect the ethical behaviour of employees, and only some personal values and goals of the organisation have a significant influence on ethical behaviour. The most significant explanatory factor of ethical decision making seems to be what may be called "stage in the career of the employee": "ethical" employees can be described as young, with a relatively low income, limited work experience and a low level of responsibility in the company.     

产业升级再解构:由三个角度观照

产业升级是一个经济学和管理学理论相结合的综合性问题。从微观—中观—宏观三维层次出发,基于经济学与管理学两个视角来系统地梳理产业升级内涵及其运作机理,以勾画出一个新的研究轮廓与框架,为我国产业升级的研究与实践提供理论依据。在完善理论框架的基础上,弥补中观层面(包括产业内部层面、行业层面)产业升级的研究缺陷,并加强产业升级速度与水平的量化研究。     

Healthy Business Environment According to the General Theory of Sustainable Development

The article continues thinking about prospective of human society. Is the healthy business environment a fiction or a real opportunity？ How far-reaching are the roots of the future natural processes of changes？ How to work with the current global economic models？ Can the current European integration process be considered as natural？ Is a weak state a new opportunity for a future strong economy？ What is the historical essence of the liberal thought？ Why the current economic models are not permanent, why are they not sustainable, and why are they not developing for the basic quantum, which is the man as an individual？ Can also the basic quantum be integration units as family, society, company, municipality, region, country, or EU, etc.？ Qualified answers to the questions can be seen in a theoretical context of the General Theory of the Sustainable Development （GTSD）, too. Theoretical trinity of GTSD is based on three theoretical pillars： GPT （Gravitation Polarity Theory）, QET （Quantum Economy Theory）, and BIT （Big Integration Theory）. They can be considered as relevant theoretical basics for historical, current, and future sustainable development process. The healthy business environment is based on the healing of man. In GTSD, businessman and man gain a new source of knowledge, a new natural relationship, and a new content. This is a responsibility towards the customer and towards the pa~ner in business. Businessman＇s profit speaks about a new business in natural partnerships. Sustainable development without the Groove Management （second generation management） and without the fourth Reformation （with second generation of innovation） is a process that only reflects the regressive trend that takes place for more than 6000 years. Without the new content of the Fifth Theoretical Dimension （Consciousness） the historical mainstream of sustainable development process cannot be grasped. The biggest risk for the expected Healthy business society is a contemporary slave commun     

Business Cycle Synchronization of Turkey with the Eurozone and the United States: What Has Changed Since 2001?

Using wavelet methodology, we make a detailed spectral analysis of the business cycle synchronization of the Turkish economy with the eurozone and the United States. We take into account the dramatic change in the main economic indicators in the Turkish economy after the 2001 financial crisis. We find that the correlation of Turkish cycles with the cycles of the eurozone and the United States increased substantially after 2001. Moreover, the correlation of the Turkish cycles with the U.S. cycles is not lower than that with the euro cycles after 2001. Accordingly, analyzing the effect of international developments should not be confined to the trade channel. We submit that capital flows offer a reasonable explanation for the high correlation with the United States.
