Prediction of the Indian summer monsoon using a stacked autoencoder and ensemble regression model

The study of climatic variables that govern the Indian summer monsoon has been widely explored. In this work, we use a non-linear deep learning-based feature reduction scheme for the discovery of skilful predictors for monsoon rainfall with climatic variables from various regions of the globe. We use a stacked autoencoder network along with two advanced machine learning techniques to forecast the Indian summer monsoon. We show that the predictors such as the sea surface temperature and zonal wind can predict the Indian summer monsoon one month ahead, whereas the sea level pressure can predict ten months before the season. Further, we also show that the predictors derived from a combination of climatic variables can outperform the predictors derived from an individual variable. The stacked autoencoder model with combined predictors of sea surface temperature and sea level pressure can predict the monsoon (June-September) two months ahead with a 2.8% error. The accuracy of the identified predictors is found to be superior to the state-of-the-art predictions of the Indian monsoon.     

论强制性环境治理制度的实施效率

In the eco-environmental governance system,the compul-sive institutions are the most important as well as the mostcommonly utilized.A nation utilizes its administrative,lawand economic power to forbid,boost,bestir and help indi-viduals’behavior concerning environmental governance toensure the realization of eco-environment conservation.The fact,however,turns out to be disappointing about theimpulsive institution’s implementation.Actually,the unsatis-factory practices sometimes even lead to“…     

我国金融监管法律制度的反思与改造

作为部门行政法律制度建构的一部分,金融监管法律制度在国家经济生活中具有十分重要的作用。目前我国的金融监管法律制度还存在着较大的缺陷,突出表现在金融监管立法不完备,法律、法规混杂、重复、遗漏及空白之处甚多,对监管主体的规定存在缺失,央行的独立监管地位弱化,关于金融监管的手段、方法的规定不完善,以致造成执法缺乏力度。在国外资金大量涉入国内、国际金融及监管规则约束国内的金融机构之前,必须完备我国的金融监管法律制度。     

超越契约理论--演化论视角的企业理论研究

企业的契约理论围绕交易成本概念解释了企业的存在、边界和内部组织,但严重忽视了企业的技术和生产功能,演化经济学的企业理论通过研究企业内知识的产生、传播和利用过程,以及组织与个人的交互学习,不仅重新解释了企业的存在、边界和内部组织问题,还研究了契约理论未触及的企业异质性、竞争优势和企业家等问题.     

The research of Chinese karst ecological hydrology

1. Introduction The area of carbonate rocks protruding through the soil level in China is 9.07*105km2. According to the area of carbonate rocks stratum protruding through the soil level, it is 2.06*106km2. With the buried carbonate rocks stratum of the different depths, its total area can reach 3.443*106km2, ap- proximately accounting for 1/3 of the national terri- torial area. Chinese carbonate rock is mainly distributed to the south of the latitude belt of Tianshan Mountain – Yinshan Moun…     

Régulation School and environment: Theoretical proposals and avenues of research

The article explores the relevance of a particular approach of the institutionalist movement, régulation theory, to deal with the relationship between the economy and the environment. Régulation theory, which appeared in France at the end of the 1970s, is mainly interested in macroeconomic issues. In contrast, until now it has tended to neglect environmental questions. By taking several key concepts of this theory (accumulation regime, mode of régulation, institutional forms), we have sought to assess its significance vis-à-vis the environmental field. More precisely, from the perspective of establishing an environmental regulationist theory, we propose considering the economic relation to the environment as the articulation of three forms: a transhistorical form, a general capitalist form and a specific capitalist form, the latter being variable in capitalist time and space. We give several illustrations of the variability of the relation to the environment, depending on the different accumulation regimes and the different modes of régulation. Two principal avenues of research are proposed: historical analyses for given economic areas, and comparative analyses relating in particular to different capitalist areas.     

休闲观光农业经营管理方案研究

休闲观光农业是一种利用田园景观、自然环境、生态资源，结合农林渔牧业生产、农村文化及农家生活，在不耽误农业生产的基础上又为城市居民提供休闲体验活动的农业经营模式。休闲观光农业能够利用当地丰富的农业资源、旅游资源和劳动力资源实现当地农业可持续发展。但它的发，晨过程也可能带来很多负面影响。这就要求我们在设计休闲观光农业的经营方案时要根据农业与旅游这两个行业的特点。通过各自的经营管理要素对其分别进行比较分析，找到了两个行业的异同，并采用经营管理构建方法。逐步导出休闲观光农业的经营方案。

民族文化变迁对生态环境保护的影响——以云南为例

我国西部生态环境保护一直是各学科关注的焦点问题,但从生态环境保护的民族文化内在驱动力这一重要角度进行研究的较少。实际上,环境保护的主体是当地居民,而环境保护观念主要受到传统民族文化的影响。本文通过对云南民族文化变迁的分析,指出了对云南民族生态文化产生负面影响的因素主要来自三方面:汉文化、近现代文明、地域权力变更与“左”倾思想。最后,探讨了解决云南民族文化与生态环境保护之间的摩擦的途径。
