A theory of innovation for process-based innovations such as nanotechnology

Many see Nanotechnology as the technology that will underlie the next Schumpeterian wave creating new opportunities for wealth and job creation. Further it is a process based or materials technology. Yet all currently used models of innovation are based on assembled products or service products and these simply do not recognize the differences in materials products nor the “enabling” nature of Nanotechnologies. If nanotechnology is poised to become the economic engine of this millennium and if current models of innovation, which are utilized, by policy makers and firm based strategist alike are based on technology product paradigms that are dissimilar to the realities of nanotechnology and other process-based technologies then there is cause for concern.Here the authors provide a model and supporting cases demonstrating a new process or materials based innovation model that is based on the tight coupling between product and process innovation of not only Nanotechnology-based products but other process-based products. This is an important finding, because it identifies and remedies a gap in the literature associated with earlier process and product innovation models. For process-based products like materials, food, chemicals and nanotechnologies any change to the manufacturing processes results in significant changes in end product features. The implications of this model to practice are considered.     

“棘轮式”代理问题与子公司经理人激励:家族集团治理

家族集团中,在企业家通过本期产出水平来确定子公司经理人所应上缴的产出分配收益的情况下,经理人会通过调整自己的努力水平,间接控制自己在下期的上缴额度,从而导致激励效率损失.但是,如果企业家能收取固定的产出分配收益,并确定高额违约金,就能够有效地规避子公司经理人代理问题.     

论知识型组织员工的人性假设及其激励

基于知识型组织员工人力资源的独有特征，提出一种新的人性假设——“价值人”假设，即知识型组织中员工是工具价值与自我价值二维存在的统一体。在“价值人”假设条件下，知识型组织员工管理模式应从传统的“命令-控制”型向“引导-激励”型转变，运用激励的制度安排来激发员工的工作热情。     

Asymmetric volatility in the foreign exchange markets

We examine the presence or absence of asymmetric volatility in the exchange rates of Australian dollar (AUD), Euro (EUR), British pound (GBP) and Japanese yen (JPY), all against US dollar. Our investigation is based on a variant of the heterogeneous autoregressive realized volatility model, using daily realized variance and return series from 1996 to 2004. We find that a depreciation against USD leads to significantly greater volatility than an appreciation for AUD and GBP, whereas the opposite is true for JPY. Relative to volatility on days following a positive one-standard-deviation return, volatility on days following a negative one-standard-deviation return is higher by 6.6% for AUD, 6.1% for GBP, and 21.2% for JPY. The realized volatility of EUR appears to be symmetric. These results are robust to the removal of jump component from realized volatility and the sub-samplings defined by structural-changes. The asymmetry in AUD, GBP and JPY appears to be embedded in the continuous component of realized volatility rather than the jump component.     

基于引力模型的中美农产品贸易边境效应研究

针对中美两国在农产品贸易上的新变化,应用引力模型的派生模型——边境效应引力模型对中美两国农产品贸易的流量和流向进行理论和实证研究。首先介绍了边境效应引力模型基本模型的推导过程,并引入了调整模型。然后采用1987至2005年其中5年的截面数据进行计算,结果发现:中美农产品贸易的边境效应显著存在,且呈逐年下降趋势;两国之间的农产品贸易边境效应存在流向和区域上的差异;距离的平方并不影响模型的可靠性。     

景区拓荒群体的旅游特征——以福建邵武天成岩为例

邵武市天成岩是一处原始旅游地,已有一些旅游者自发而来。这些拓荒群体以中青年为主,他们多数经人介绍获得信息,以猎奇心态对景区观光漂流体验活动感兴趣,他们希望景区保持原样,不要太多人为干扰。这些拓荒群体的旅游特征对原始旅游地开发具有一定的指导意义。     

论公正及其与自由、平等的关系

尽管学术界对自由、平等和公正问题有许多研究和阐释,但较少将自由、平等与公正问题联系起来从总体上进行考察和研究,以致关于自由、平等和公正及其关系问题成了人们最说不清、道不明的问题。本文试图立足于当代人类社会现实及其走向,着重从与自由、平等相互关联的视角研究公正问题,力求纲要性地对公正及其与自由、平等之间的关系提供一些阐释和见解,最终论证这样一种基本观点:现代公正是一种综合性的价值要求,它要求社会自由和平等,也要求对自由和平等可能导致的社会问题给予适当解决。     

当代艺术审美理想的迷失与重建

中国当代艺术审美理想的迷失从根子上说是有些中国作家和艺术家社会背叛的结果,从美学上说,不但是席勒当年所批判的恶劣倾向的沉渣泛起,而且消解了人对自己的尊严的捍卫和对自由的追求。中国当代艺术审美理想的重建就是要求中国作家和艺术家精神寻根,按照美的规律创造。
