Sex Ratio at Birth and Infant Mortality Rate in China: An Empirical Study

Abstract: In this article, we used the data from the last three population censuses of China in 1982, 1990 and 2000, to study the dynamics of the sex ratio at birth and the infant mortality rate in China. In the late 1970s, China started its economic reform and implemented many family planning programs. Since then there has been great economic development and a dramatic decrease in fertility in most of its provinces. Along with these achievements, the sex ratio at birth of the Chinese population has increased to significantly more males to females, and in some provinces of China reached unprecedented levels. The ratio of infant mortality of the males to females for many provinces in China become extremely unbalanced with a much higher female infant mortality rate. In our study, we investigated the statistical relationship between the sex ratio at birth and the ratio of the infant mortality of males to female. Social and economic reasons for these unnatural trends are also discussed.

On the Measure of Complexity

Abstract: the measure of complexity for a system is called degree of complexity. But until now, there is no commonly means to suitable for all complexity systems. In generally, we measure the degree of complexity for a system from one point of view or parameter. Currently, structure complexity, computational complexity, description complexity, and effective complexity are some well-rounded measure and we can use these means to measure the complexity of a system how complex it has.

Linkages and relationships between Emerging European and Developed Stock Markets before and after the Russian Crisis of 1997-1998

Abstract: We examine the relationship between Russian and other Central and Eastern European equity markets over the 1995-2004 period. Using traditional Johansen and Juselius multivariate cointegration approaches and examining Impulse Response Functions from VECM's we find that the extent of the relationship differs markedly before and after the Russian crisis of 1998. However, further examination, using the Gregory-Hansen approach, indicates that the effect of the Russian crisis is more complex, and that Russian market shows significantly more evidence of integration with developed markets since, albeit the extent of interdependencies differs in case of the US and European markets. A DCC model indicates that the conditional relationship between the Russian market and the main developed markets is, as shown by the Gregory-Hansen approach, shifting.

Russian equity market linkages before and after the 1998 crisis: Evidence from time-varying and stochastic cointegration tests

Abstract: This paper examines the relationships between the Russian and other Central European (CE) and developed countries' equity markets over the 1995-2004 period. Along with the traditional Johansen and Juselius (1990) multivariate cointegration tests, we apply novel cointegration approaches, including Gregory-Hansen (1996) test, which allows for a structural break in the relationships, as well as the newly developed stochastic cointegration test by Harris, McCabe and Leybourne (2002) and the non-parametric cointegration method of Breitung (2002). The latter tests point to a significant agreement that in the aftermath of the Russian crisis of 1998 there was an increasing degree of comovements of the Russian market with other developed markets, but not with CE developing markets. This result is further confirmed by dynamic conditional correlation modeling, which allows us to investigate graphically the evolution of comovements in the system. The results of detailed cointegration analysis suggest a. that the time-varying nature of equity markets comovements should be explicitly accounted for while modeling long run relationships b. that there is a decline in diversification benefits for foreign investors seeking to invest in Russian equities over the long horizon.

Comparing two clinical measurements: a linear mixed model approach

Abstract: In this article, we extended the widely used Bland–Altman graphical technique of comparing two measurements in clinical studies to include an analytical approach using a linear mixed model. The proposed statistical inferences can be conducted easily by commercially available statistical software such as SAS. The linear mixed model approach was illustrated using a real example in a clinical nursing study of oxygen saturation measurements, when functional oxygen saturation was compared against fractional oxy-hemoglobin.

An APGARCH Investigation of the Main Influences on the Gold Price

Abstract: The paper investigates whether the asymmetric power GARCH model (APGARCH) introduced by Ding, Granger and Engle (1993) captures the dynamics of the gold market. This paper examines both the cash and futures price of gold and significant economic variables identified during two periods: the 1987 crisis and the 2001 crisis. As specified in Ding et al. (1993) a number of ARCH and GARCH models are nested within the APGARCH model. To estimate the goodness of fit of each model, likelihood ratio tests are used. The results suggest that APGARCH model provides the most adequate description for the data. This paper is the first of its kind to undertake a significant GARCH model of the main influencers on the gold price. While further investigation is required, it has unearthed interesting results.

Locating human eyes using edge and intensity information

Abstract: In this paper, a new eye detection method is presented. The method consists of three steps: (1) extraction of binary edge image (BEI) based on the multi-resolution analysis of wavelet transform; (2) extraction of eye region and segments from BEI, and (3) eye localization using light dot or intensity information. An improved face region extraction algorithm and a light dot detection method are proposed to improve eye detection performance. Experimental results show that our approach can achieve a correct eye detection rate of 98.7% on 150 Bern images with variations in view and gaze direction and a rate of 96.6% on 564 AR images with different facial expressions and lighting conditions.

Are Weather Induced Moods Priced in Global Equity Markets

Abstract: Recent research in behavioural finance has tested for evidence of mood misattribution influencing investor decision-making. The approach adopted is to test for a relationship between widely experienced mood proxy variables and equity returns. Variables ranging from weather, to Seasonal Affective Disorder (SAD), to sporting events, amongst other variables, have all been used in the process of these investigations. This paper conducts a comprehensive, econometrically robust, analysis of the influence of mood proxy variables across a global range of 37 equity market indices and 22 small cap indices. Our study combines key mood proxy variables tested in a range of previous papers in one study. We specifically test for SAD, Daylight Savings Time Changes, lunar, and geomagnetic effects. Only SAD appears to have any effect, worldwide.

Integration among G7 Equity Market : Evidence from iShares

Abstract: We study the evolution of global equity market integration using US dollar denominated iShares. Designed to mimic the movements of MSCI indices, these securities provide an easy pool of international diversification products for the investor. As such they allow us to conduct an analysis of the largest equity markets comovements devoid of problems associated with trading restrictions, exchange rates fluctuations and non-synchronous trading. In contrast to most of the previous studies, we apply time varying methodology for the analysis of both short-term and long-term comovements that provide detailed evidence on the pattern and dynamics of the equity market linkages. We find evidence in favour of increasing conditional correlations for all of the markets since 2001. Time-varying and recursive cointegration tests provide somewhat weak evidence in favour of the presence of bivariate cointegration relationships, but stronger evidence in the multivariate case, suggesting limited diversification opportunities for the U.S. based investor in the long run.

Remote sensing image classification method based on support vector machines and fuzzy membership function

Abstract: At present neural network models make great progress in remote sensing image classification, but these models have some serious limitations, such as easily getting stuck at a local minimum, converging too slowly and uneasy-fixed network structure. Support vector machines (SVMs) is a nonlinear mapping algo rithm based on the Statistical Learning Theory, and developed over the last three decades by Vapnik, Chervonenkis et al. It gained extensive applications in pattern recognition and regression analys is etc. Compared the SVM algorithm with neural network models, the former is based on self-contained mathem atics theory, and furthermore solves a global optimization problem and makes sure the result is not local minimum. These enable the SVM algorithm excellent classification performance. The paper proposed a new hybrid classifica tion method that combines support vec tor machines with fuzzy membership function for remote sensing image. Firstly the method constructs multi-class Support Vector Machines classifier for remote sensing image, and discusses parameter estimation prob lem, and then uses RBF kernel SVM to classify whole remote sensing image. Secondly aiming at the disadvantage of SVM classifier that exists some mixed samples (one sample divided into two or more categories) and missed samples (one sample is not classified), and using fuzzy membership function method to reclassify these mixed and missed samples. Experimental results suggested the accuracy of this hybrid classifier is higher than single SVM method , or single fuzzy membership function decision method or BP neural network model. Key Words: Remote Sensing Image Classification, Support V ector Machines, Fuzzy Membership Function, BP neural network

Joint source-channel coding for MPEG-4 streams transmission over 3G networks

Abstract: The aim of the 3rd generation networks is to combine the multimedia services over Internet and provide them on wireless mobile platforms. The stability, interoperability and robustness offered by MPEG-4 (moving picture experts group) make it an ideal solution for mobile networks, and it has been selected by 3GPP (the 3rd generation partnership) and 3GPP2 for 3G phones. Burst and random bit errors introduced by fading channels degrades MPEG-4 streams. Conventional error correcting techniques cannot correct these errors. In this paper, a JSCC (joint source-channel coding) method based on MPEG-4 system and turbo coder has been proposed. The critical important MPEG-4 streams such as the BIFS (binary format for scenes), OD (object descriptors) and IOD (initial object descriptors) streams are transmitted by using TCP (transmission control protocol), and MPEG-4 audio/video ES (elementary streams) are transmitted by using UDP (user datagram protocol) over 3G channels. Transmission UDP packets is adopted UEP (unequal error protection) turbo codes according to MPEG-4 audio/video data partitioning. Simulation results show that this method can effectively improve the performance.

Efficient evaluation of sibling relationship in Xpath queries

Abstract: The structure queries of XQuery result in structural joins of various relationships. While several efficient algorithms have been proposed in evaluating ancestor-descendant and parent-child relationships, few efforts are put on the study on sibling relationship. In this paper, we study the structural joins of preceding-sibling-following-sibling relationship. To accelerate structural joins of parent-child and preceding-sibling-following-sibling relationships, optimizing techniques are employed to filter out and minimize unnecessary reads of elements using parent's structural information. Then, two efficient structural join algorithms in evaluating sibling relationship are proposed, in which nodes that do not participate in the join can be judged beforehand and then skipped using B+-tree index. Besides, each element list joined is scanned sequentially once at most. Furthermore, output of join results is sorted in document order. Our experimental results not only demonstrate the effectiveness of our optimizing techniques for sibling axes, but also validate the efficiency of our algorithms. To the best of our knowledge, this is the first effort that addresses this problem.

Decomposition of Chinese Life Expectancy via Occupation

Abstract: In this article, we applied the concept of partial life expectancy to calculate the expected years of working life via occupation for the Chinese population beyond age 15. The calculations were based on the data from the population censuses of China in 1982, 1990 and 2000, which covered the period of eighteen years from the early economic reform years to the end of last century when the market economy became the official goal of the Chinese government. From our study, we found that, using partial life expectancy as the indicator, majority of the working life of the Chinese population has been on farming although it was slowly declining for both sexes from 1982 to 2000. In 1982, the expected years of working life on farming were 30.98 years for males and 26.45 years for females. In 2000, these values decreased to 27.09 and 26.16 years respectively. However, the expected years of working life in service sector increased from 1.88 years and 1.57 years in 1982 for males and females to 3.35 years for both sexes in 2000.

On Translation's Acceptability

Abstract: Translation serves readers.In the course of translation,translators must consider translations acceptability.Only the translation accepted by readers can be considered as a successful translation.Translations acceptability has the dynamic characteristics and varies according to different readers and situations.Translations acceptability can be judged from the following aspects:(1) whether the translated version is normal and the style is appropriate as far as the level of language expression is concerned;(2) whether translation corresponds to the readers aesthetic interest and the cultural background in the aspect of the cultural orientation;and (3) whether translation achieves the communicative purpose in the aspect of communicative function.

Evaluation of a crossover router based qos mechanism in fast mobile IPv6 networks

Abstract: A “Crossover Router” (CR) based QoS provisioning mechanism under an enhanced “Fast Handovers for Mobile IPv6” (FMIPv6) architecture has been proposed to provide better performance for multimedia applications in Mobile IPv6 (MIPv6) networks. In the proposal we extend the FBU and HI messages to notify the QoS requirement of “Mobile Node” (MN). Advance reservations along the possible future-forwarding paths are performed only between CR and MN to reduce reservation hops and signaling delays. In this paper we present the detailed performance evaluation results of this scheme compared with “Mobile RSVP” (MRSVP) protocol, using the network simulator (NS-2). In the simulations RSVP signaling cost, total bandwidth requirements, RSVP signaling and data packet delay in different scenarios of both schemes were considered. Results show that the proposed scheme for QoS guarantee has lower RSVP signaling cost and delay, as well as less bandwidth requirements in comparison with MRSVP. Furthermore, fluctuation and peak values of data packet delays in different scenarios are much lower.

A study on the development and tactics of e-government construction of Jiangxi province

Abstract: As an effective means to develop our country's information construction, E-government must go ahead. It is not only the requirement for the transformation of government structure and function, but also an important measure for China's response to the change after her access to WTO. As a model province for the promotion of national information construction, Jiangxi has taken the lead in the construction of E-government. The opening of the information network of Jiangxi government in early 2003 represents the milestone of Jiangxi E-government. However, we must realize that there are still lots of problems in the construction of our E-government, and should try to find out solutions in order to scale new heights of Jiangxi E-government. This paper analyzes some current problems in the construction of Jiangxi E-government, and then advances some suggestions for the improvement.
