Nonlinear Drift And Stochastic Volatility: An Empirical Investigation Of Short-Term Interest Rate Models

In this article I provide new evidence on the role of nonlinear drift and stochastic volatility in interest rate modeling. I compare various model specifications for the short‐term interest rate using the data from five countries. I find that modeling the stochastic volatility in the short rate is far more important than specifying the shape of the drift function. The empirical support for nonlinear drift is weak with or without the stochastic volatility factor. Although a linear drift stochastic volatility model fits the international data well, I find that the level effect differs across countries.     

三相四线统一电能质量调节器的控制策略

针对电网输入电压的不平衡、非正弦及负载的不平衡、非线性特性，提出了一种基于三相静止坐标系下的三相四线统一电能质量调节器（UPQC）的协调控制策略。该策略将UPQC的串联变流器控制为基波正弦电流源，而并联变流器控制为基波正弦电压源，从而实现了三相四线UPQC对电能质量的综合控制能力，既改善了电网侧的电能质量问题，实现了电网输入电流的正弦及单位输入功率因数，也改善了负载侧的电能质量问题，实现了负载电压的平衡、额定及正弦。10 kVA系统实验装置的实验结果表明了该控制策略的有效性。     

A consumer education programme based on the Transtheoretical Model of Change

MONEY 2000? is a successful consumer education programme that was implemented by Cooperative Extension personnel in over two dozen states of the USA between 1996 and 2002. One of the unique features of this programme is that it was based on the Transtheoretical Model of Change (TTM), a framework that has been widely used to study health‐related behaviour changes such as smoking cessation. This paper first describes how the MONEY 2000? programme was developed around major constructs contained within the TTM. Findings are reported from a survey conducted with participants in the first two states that delivered the programme. The findings suggest that several change processes used by MONEY 2000? participants are associated with specific stages of change. In addition, there may be differences in behavioural changes between participants who increased their savings and those who reduced their debts.

Can Chinese Discuss Conflicts Openly? Field and Experimental Studies of Face Dynamics in China

Chinese people have been theorized to be particularly sensitive to social face and avoid direct discussion in conflict to promote interpersonal harmony. Social face has been used to explain the proclivity of East Asians to smooth over conflict. More research is needed to study social face empirically and its relationship with direct discussion and the processes by which social face has its impact. Results from a field interview study and an experiment conducted in China support theorizing that confirmation of face induces cooperative goals and open-mindedness. In contrast with common assumptions about Chinese organizations, direct discussion, compared to avoiding, strengthened relationships. Direct controversy, especially when face was confirmed, induced open-mindedness: Participants asked more questions, explored the opposing views, demonstrated more knowledge of the opposing arguments, and worked to integrate views. These results were interpreted as suggesting that Chinese people can discuss their conflicts directly and cooperatively when they are assured that their face is confirmed. Results have implications both for the general theory of cooperation and competition as well as our understanding of social face in China.
