浅谈非线性编辑与线性编辑

线性编辑(lineareditlng):是传统的视频编辑方式.线性编辑系统由一台放像机、一台录像机和编辑控制器组成,也可以由多台录、放像机加特技设备组成复杂系统.通过放像机选择一段合适的素材,然后把它记录到录像机中的磁带上,再寻找下一个镜头,然后再记录,如此反复,直到把所有的素材都按顺序剪辑记录下来.非线性编辑(non-linearediting):是针对线性编辑而言的,简称非编.非线性编辑系统实际上是扩展的计算机系统,由一台高性能计算机和一套视颇、音频输入/输出卡(即非线性编辑卡),配上一个大容量scsi磁盘阵列便构成了一个非线性编辑系统的基本硬件.非线性编辑系统直接从计算机的硬盘中以帧或文件的方式存取素材、进行编辑.

Nonlinear price impact and portfolio choice

In a market with price impact proportional to a power of the order flow, we find optimal trading policies and their implied performance for long‐term investors who have constant relative risk aversion and trade a safe asset and a risky asset following geometric Brownian motion. These quantities admit asymptotic explicit formulas up to a structural constant that depends only on the curvature of the price impact function. Trading rates are finite as with linear impact, but are lower near the target portfolio, and higher away from the target. The model nests the square‐root impact law and, as extreme cases, linear impact and proportional transaction costs.     

MVM's Nonlinear Internationalization: A Case Study

This article aims to contribute to the international and East-West business literature by discussing the nature of nonlinear internationalization based on a case study of an Italian firm, Meccanica Valle Metauro S.r.l., that had activities in Central and Eastern Europe and other countries and by identifying causes of nonlinearities. The study concludes that nonlinear internationalization may be caused by different internal and external factors and actors; that it can occur once or several times; that foreign market exit may be temporary (followed by re-entry) and permanent; and that de-internationalization does not always mean a failure for the firm.     

Nonlinear Taylor rules in Central Eastern European countries

This study applies sequential panel selection method (SPSM), proposed by Chortareas and Kapetanios (2009) Chortareas, G., and G. Kapetanios. 2009. “Getting PPP Right: Identifying Mean-Reverting Real Exchange Rates in Panels.” Journal of Banking and Finance 33: 390–404.[Crossref], [Web of Science ®] , [Google Scholar], to investigate to test the validity of Taylor rules to assess the nonstationary properties of the convergence of the real exchange rates for 10 Central Eastern European countries. The SPSM can be used to decompose a panel of real exchange rate series into two groups: a group of stationary series and a group of nonstationary series. We identify the stationary processes in the panel and demonstrate that Taylor rules holds for 7 of the 10 countries studied. These results imply that the choices and effectiveness of the monetary policies in Central Eastern European economies are highly influenced by external factors originating from the United States. Additionally, our findings highlight that their real exchange rate convergence is a mean reversion toward equilibrium values of Taylor rules in a nonlinear manner.

A Nonlinear Model of the Term Structure of Interest Rates

We present an economically motivated two–factor term structure model that generalizes existing stochastic mean term structure models. By allowing a certain parameter to acquire dynamical behavior we extend the two–factor model to obtain a nonlinear three–factor model that is shown, in a deterministic version, to be equivalent to the Lorenz system of differential equations. With reasonable parameter values the model exhibits chaotic behavior. It successfully emulates certain properties of interest rates including cyclical behavior on a business cycle time scale. Estimation and pricing issues are discussed. Standard PCA techniques used to estimate HJM type models are observed to be equivalent to dimensional estimates commonly applied to 'spatial data' in nonlinear systems analysis.
It is concluded that techniques commonly used in the analysis of nonlinear systems may be directly applicable to interest rate models, offering new insights in the development of these models. Tests of nonlinearity in interest rate behavior may need to focus on long cycle times.
