心灵的失落与追寻——简论汉末男性诗人的女性同构心理

汉末男性诗人以女性为情感载体来抒写自我生命痛苦的写作用意,应与他们的处境和心态密切相关。在混乱的政局中经历了期盼、失望、绝望的心路历程之后,他们的心态发生了很大变化,具有与女性心理同构的新特点。这恰恰彰显了汉末男性诗人摆脱心灵困境时的自我突围意识。     

Towards Enhancement of the Economy of a Thermal Power Generating System through Prediction of Plant Efficiency

The plant ‘Heat Rate’ (HR) is a measure of overall efficiency of a thermal power generating system. It depends on a large number of factors, some of which are non-measurable, while data relating to others are seldom available and recorded. However, coal quality (expressed in terms of ‘effective heat value’ (EHV) as kcal/kg) transpires to be one of the important factors that influences HR values and data on EHV are available in any thermal power generating system. In the present work, we propose a prediction interval of the HR values on the basis of only EHV, keeping in mind that coal quality is one of the important (but not the only) factors that have a pronounced effect on the combustion process and hence on HR. The underlying theory borrows the idea of providing simultaneous confidence interval (SCI) to the coefficients of a p-th p(≥1) order autoregressive model (AR(p)). The theory has been substantiated with the help of real life data from a power utility (after suitable base and scale transformation of the data to maintain the confidentiality of the classified document). Scope for formulating strategies to enhance the economy of a thermal power generating system has also been explored.     

HEAVY-TAILED-DISTRIBUTED THRESHOLD STOCHASTIC VOLATILITY MODELS IN FINANCIAL TIME SERIES

To capture mean and variance asymmetries and time‐varying volatility in financial time series, we generalize the threshold stochastic volatility (THSV) model and incorporate a heavy‐tailed error distribution. Unlike existing stochastic volatility models, this model simultaneously accounts for uncertainty in the unobserved threshold value and in the time‐delay parameter. Self‐exciting and exogenous threshold variables are considered to investigate the impact of a number of market news variables on volatility changes. Adopting a Bayesian approach, we use Markov chain Monte Carlo methods to estimate all unknown parameters and latent variables. A simulation experiment demonstrates good estimation performance for reasonable sample sizes. In a study of two international financial market indices, we consider two variants of the generalized THSV model, with US market news as the threshold variable. Finally, we compare models using Bayesian forecasting in a value‐at‐risk (VaR) study. The results show that our proposed model can generate more accurate VaR forecasts than can standard models.

国际转移定价及其税务规制研究

我国加入WTO后,跨国公司大举进军中国市场,国际转移定价滥用问题日益突出。我国应该采取措施,强化转移定价滥用行为监督管理意识,完善转移定价税制,建立和健全审计制度,改善监管手段,同时加强国际合作,加大对转移定价滥用行为的监管和惩处力度。     

论政治运行的协调稳定机制

政治运行过程由政治决策、政治执行、政治协调、政治参与、政治监督等环节组成,可能出现良性、中性或恶性三种不同的结果状态。政治良性运行即政治的协调稳定发展。实现政治的协调稳定发展,社会必须为之提供必要的外部保障,但最根本的途径是要加强政治运行过程各环节的综合建设。     

浅析正在形成中的电子资金划拨法

电子资金划拨正以其高效率低成本的巨大优势,逐渐取代票据等传统的支付方式,得到广泛的应用与推广。这种新的支付方式的出现,也促成了以它为调整对象的电子资金划拨法的产生与发展。本文尝试对这一正在形成中的法律进行探讨,以期引起社会各界尤其是法学界对此的重视与研究,从而对我国在进行相关立法时有所裨益。
