用分形几何学的方法研究影响美国股票市场的重大历史事件

边缘点分析方法是我们为了研究金融数据中蕴含的历史事件之间的相关性问题所提出的一种创新方法。该方法基于重构相空间理论,通过探测金融数据的递归图中历史数据之间的相近程度,把时间序列中点与点之间的关系问题转化为历史事件之间的关系问题,实现探测影响金融市场任一时间区域的重大历史事件的目的。本文,我们将此方法应用于美国股票市场的分析当中,得到的结果与现实情况很吻合。     

统计工作中的问题及对策分析

近几年，统计工作获得了一定的进展，不断推动统计方法制改革，注重数据质量，重点提高统计服务水平，经济和社会的不断发展对统计工作提出了更多的要求，要求全面的统计数据和较高的统计质量。可是，当前统计工作比较薄弱，存在着一些问题，为了满足社会和经济对统计工作的需求，提出了几点建议。     

探讨化归思想在数学解题中的运用

数学问题的解决是需要一定逻辑思维的，在看似复杂的问题中，提炼出所需的数据，将问题还原到自己能掌握的范围内加以解决。在所有数学解题思想中，化归思想尤为重要。如果遇到难度系数较高的题，我们可以将原本的问题转换角度进行思考，把它变成一个相对简单的问题，就如同把复杂的问题简单化一般。至此．本文就化归思想进行了全面的剖析

自回归模型在杭州公共自行车使用量预测中的应用

自回归是基于数据的统计性质建立模型。它把系统中每一个内生变量作为系统中所有内生变量的滞后值的函数来构造模型,从而将单变量自回归模型推广到由多元时间序列变量组成的向量自回归模型。本文通过一些数据对向量自回归模型进行拟合,从而获得预测精度较高的预测模型。

Penetration and Post-infection Development of Meloidogyne Incognita on Tobacco as Treated by Rhizobacteria Pseudomonas Fluorescens Strain P-72-10

The bio-control potential of rhizospere bacteria Pseudomonas fluorescens against plant-parasite nematode had been demonstrated. P. fluorescens had shown the effect to enhance tobacco resistance to root-knot nematode Meloidogyne incognita. Inoculation with P. fluoreseens in tobacco could lead to significant reductions in the number of juveniles that penetrated tobacco root and further life stage development of the juveniles. The number of juveniles penetrated into tobac- co root in treatment with P. fluorescens is significantly different from CK at 2DAI, 6DAI, 8DAI and 10DAI. Significant reduction and delayed development of juveniles that penetrated into tobacco root and treated were observed in treatment at 14DAI, 21DAI, 28DAI and 35DAI. In addition, P. fluoreseens treatment leads to a significant reduction in the number of eggs per egg-mass at 35 DAI. The results show P. fluorescens induced a continuously suppression on root-knot nema- tode M. incognita throughout their entire early infection phase of root penetration, subsequent life stage development and reproduction.

Taxing Times in Indonesia: The Challenge of Restoring Competitiveness and the Search for Fiscal Space

Indonesia’s economic growth picked up slightly in mid-2016 but remains below the level demanded by government and popular aspirations. Despite a plethora of reforms intended to increase efficiency and productivity, some policies are perverse and longstanding problems of implementation remain. The share of manufacturing has declined, the real exchange rate has appreciated, exports have dwindled, and growth has been trending downwards. The banking sector is stable but inefficient, with wide net interest margins and numerous barriers to competition. Trade protection, particularly in basic food commodities, has created high costs that weigh particularly heavily on the poor. Declining government revenues have placed increasing pressure on the public budget, even as the current administration aims to increase spending on infrastructure and welfare and to enhance productivity. In an effort to increase revenues, the government has announced a tax amnesty program and other measures. In addition, Sri Mulyani Indrawati, the new finance minister, has taken steps to cut non-essential expenditure in order to secure high spending on infrastructure and at the same time keep within the 3% budget deficit limit stipulated by law. Although the overall debt situation is not yet alarming, declining revenues and budget cuts that do not fully reflect this decline are putting pressure on increasing debt levels. The government’s high-profile tax amnesty program was the major policy initiative implemented in the second half of 2016 that aimed to relieve this pressure. Despite widespread criticism of, and scepticism about, the tax amnesty (both within and outside Indonesia), its first phase had a much higher participation rate than most independent accounts expected. Revenues raised so far through the amnesty are less than 60% of the official target, but this is actually a strong result for the short term. The bigger question, however, is whether the amnesty is a key element of a more encompassing strategy to overhaul the system of taxation and tax administration.     

The causes of Japan's ‘lost decade’: The role of household consumption

In this paper, I analyze the causes of the prolonged slowdown of the Japanese economy in the 1990s and find that the stagnation of investment, especially private fixed investment, was the primary culprit. I then investigate the causes of the stagnation of household consumption during the 1990s and find that the stagnation of household disposable income, the decline in household wealth, and increased uncertainty about the future are among the contributing factors. Finally, I consider whether demand side factors or supply side factors were more important as causes of the prolonged slowdown of the Japanese economy in the 1990s and conclude that the former (especially misguided government policies) were probably more important.

城市社会的开放与农民的城市化

城市社会在对农民的开放与封闭之中徘徊。改革开放后城市社会对农民的开放已经使很多农民城市化。城市社会对农民的封闭已由政策性封闭转向经济性封闭。城市社会对农民的封闭增加了农民城市化的成本和社会风险。必须加强城市社会对农民的开放,逐步消除对农民的封闭政策,以推进农民的城市化。
