Recurrence plots analysis of the CNY exchange markets based on phase space reconstruction

The employment of autocorrelation-based transformation to study the dynamics of the exchange rate system is meaningful because it benefits for chaotic prediction on the basis that the transformation from an exchange rate sequence to its associated autocorrelation sequence is reversible. This paper examines the influence of autocorrelation-based transformation on the systemic dynamics using exchange rates of CNY against different currencies among USD, EUR, JPY, GBP, MYR and RUB. First, we construct recurrence plots of exchange rate return sequences and autocorrelation sequences with a fixed sliding window length of 20. The recurrence quantification analysis (RQA) shows that the exchange rate return sequences exhibit lower degrees of determinism than the autocorrelation sequences. Further, by analyzing the RQA measures with bootstrap techniques and box plots, we reveal that the RQA measures of the exchange rate return systems and the autocorrelation sequence systems are mostly significant, and the vertical structures of recurrence plots of autocorrelation sequences are more sensitive to the shuffles of bootstrap techniques. Finally, we investigate the evolution of RQA measures with the changes of sliding window lengths. The analysis shows that appropriately adjusting the sliding window length can increase the systemic determinism.

云南省城镇居民消费与收入关系的非参数回归分析

近二十多年来,非参数统计的方法已广泛应用于计量经济学的研究。由于不需要预先确定变量间的函数关系,对计量经济模型的估计和预测提供了多方面和灵活机动的表现形式。本文尝试将非参数估计理论引入到回归模型中,通过建立非参数回归模型及普通的线性回归模型对云南省城镇居民可支配收入及消费之间的关系进行比较研究。     

DEVELOPMENT PRESSURES AND HERITAGE IN THE PERTH CENTRAL BUSINESS DISTRICT, 1950–90

This article examines the remaking of Perth's Central Business District (CBD) during the 1950–90 period. It traces the establishment of a modernist development ethos in Perth's planning, outlines the inadequacy of the City's planning regulations, and analyses the impact on St George's Terrace, the city's main commercial thoroughfare. The City Council was largely incapable of restraining excessive development and the extension of its system of plot ratios encouraged manipulation to increase the height of developments. Several important historic buildings were demolished because there were no legal means of safeguarding the city's heritage until 1990.

人物命运遭际的哲理思索

石杰的长篇小说《狗鱼》,以外科医生林雨在反右派运动中遭遇为主线,反映了一个县级医院里各种不同人物的利害角逐,活画岀人性的高尚与卑污,展示了时势乖误中的复杂矛盾及其延续性的后果。对此,小说作者以睿智的哲理加以分析,显示了动人心魄的艺术感染力。

Descriptive statistics of large data sets by scatter plots, an exploratory approach

In the analysis of large tables of M variables on N observations one is interested in the relations between the variables and it is usual to inspect the M(M-1)/2 scatter plots of N points. Clearly, the scatter plot approach relies on visual inspection and is to be preferred in so far as applicable to detect simple relations, namely when M is small. Other approaches are needed for large values of M .
We consider that only the relatively few scatter plots that present a 'structure' are of interest for an exploratory analysis and, by 'structure', we mean a domain of specially high local density in the plot. Based on this concept, we propose a method constructed around two steps: the selection of the possibly interesting pairs of variables and the validation of the corresponding scatter plots. The selection of the pairs results from an algorithm based on a binary partitioning tree. The validation of the corresponding scatter plots enables the production of only those where a structure is found the recognition of a structure is derived from a statistic based on the length of the Minimum Spanning Tree constructed on the N points of the candidate scatter plot.
For illustration, we report on an industrial application where the method is routinely applied for exploratory purposes.     

Chaucer's Craft in Telling Philosophical Lessons in "The Manciple's Tale"

"The Manciple's Tale" is a beast fable. Chaucer is a genius both in designing creative plots and teaching philosophical lessons in this beast fable. Chaucer arranges the Manciple to tell the story and the Manciple lets the animals tell the truth. Chaucer combines two philosophical lessons and his creative plot together perfectly.     

论《白衣女人》的主题情节

英国著名侦探小说家威尔基·柯林斯的代表作《白衣女人》一书不仅开创侦探小说之先河,且在写作手法上亦为英国小说另辟了一条新的蹊径。作为长篇侦探小说,《白衣女人》是关于拯救＂受困的公主＂及寻找社会身份的认同的文学作品,其故事枝蔓纵横、错综复杂,因而理清其主题情节就显得尤为重要。
