中国林业NGO对外交流面临的机遇和挑战

随着NGO在林业国际事务中的作用日渐显现,以及我国林业事业对外交流的需求不断增强,中国林业NGO对外交流迎来了良好的机遇期,同时也面临着诸多问题和挑战。通过对林业NGO对外交流现状以及存在问题的介绍与分析,提出了今后我国林业NGO对外交流的具体建议。     

试析林木资产的计价入账方法

林木资产计价入账方法的选择是森林资源资产会计核算的重要问题之一。林木资产计价可供选择的方法主要有历史成本法和现行市价法两种,这两种方法各自有其适用条件、适用范围及优缺点,但相对而言历史成本法更为适合,因此,在对林木资产计价核算时应始终坚持能够用历史成本计价的尽可能用历史成本计价,不具备历史成本计价条件的再考虑用其他方法。     

文化涵化和传播理论的物理学原理解释

文化的传播总体上来说是强势民族文化向弱势民族文化传播,但个别文化元素的传播可能是逆向的。文化的传播或涵化只有在存在文化差异(也即文化势差)的情况下才会发生,只有文化差异没有文化传承者的接触也不会产生文化的传播或涵化。但这种接触可以是文化传承者(人)的直接接触,也可以通过"场"的间接接触,接触的密切程度由若干因素确定。文化传播或涵化强度可以采用渗流理论(v=ki)或电流理论(I=V/R)来表达;接触的密切程度可以用渗透系数k或传导阻力R来表示,接触程度越紧密,文化传播或涵化的强度越大,即渗透系数k越大或传导阻力R越小;文化差异(文化势差)可以用水力坡降i或电势差V来表示,文化势差越大,文化的涵化或传播强度越大。     

居民消费能力视角下的中国经常账户顺差影响因素协整分析

持续、巨额的经常账户顺差给中国带来了一系列负面影响。彻底扭转中国经常账户失衡,迫在眉睫。文章基于居民消费能力的视角,对中国经常账户问题进行了理论和实证分析。理论研究结果表明,居民消费能力是影响中国经常账户的主要因素;实证研究结果表明,中国经常账户顺差与居民消费能力、投资率、净国外资产比率和人口抚养比存在长期动态均衡关系,其中居民消费能力是影响经常账户的重要因素且与经常账户余额/GDP呈负相关关系。最后文章提出了相关的对策和建议。     

Global and Euro Imbalances： China and Germany

We analyze global and euro area imbalances by focusing on China and Germany as large surplus and creditor countries. In the 2000s, domestic reforms expanded the effective labor force, restrained wages, shifted income toward profits and increased corporate saving. As a result, the Chinese and German current account surpluses widened, and that of Germany has proven more persistent, with subdued domestic investment. China is an early-stage creditor, holding a short equity position and a longposition in safe debt. Germany＇s balanced net debt and equity claims mark it as a mature creditor thatprovides insurance to the rest of the world. China pays to lay off equity risk, while Germany, by contrast, harvests a moderate yield on its net claims. In both economies, the shortfall of the net international investment position from cumulated current account surpluses arises from exchange rate changes, asymmetric valuation gains, and, in Germany＇s case, credit losses.     

An intelligent and secure system for predicting and preventing Zika virus outbreak using Fog computing

Zika virus is a mosquito-borne disease that spreads very quickly in different parts of the world. In this article, we proposed a system to prevent and control the spread of Zika virus disease using integration of Fog computing, cloud computing, mobile phones and the Internet of things (IoT)-based sensor devices. Fog computing is used as an intermediary layer between the cloud and end users to reduce the latency time and extra communication cost that is usually found high in cloud-based systems. A fuzzy k-nearest neighbour is used to diagnose the possibly infected users, and Google map web service is used to provide the geographic positioning system (GPS)-based risk assessment to prevent the outbreak. It is used to represent each Zika virus (ZikaV)-infected user, mosquito-dense sites and breeding sites on the Google map that help the government healthcare authorities to control such risk-prone areas effectively and efficiently. The proposed system is deployed on Amazon EC2 cloud to evaluate its performance and accuracy using data set for 2 million users. Our system provides high accuracy of 94.5% for initial diagnosis of different users according to their symptoms and appropriate GPS-based risk assessment.

浅谈经济法视角下青海藏区乳业经济的发展

随着市场经济的快速发展,社会日益复杂化,科技的发展极大地改善了人们的生活条件和生活质量的同时对人们的生存又带来了前所未有的威胁。作为社会经济细胞的经济活动主体---企业,在推动社会经济发展做出贡献的同时,由于其＂经济人＂的天性,在市场竞争中,往往驱使其为追逐利润而沦丧商业道德,致使侵犯消费者权益的事件频发。这不仅阻碍了企业的发展和存续,严重影响了地方行业经济的发展,扰乱了经济秩序,又破坏了市场经济的有序运行。本文通过对乳业食品安全事件成因的深入分析,结合青海乳业经济现状,从经济法的角度提出完善青海省乳业经济发展的建言,以促进青海省乳业经济的健康、有序发展。     

河南省普通高校高水平运动队发展研究

从河南省普通高校高水平运动队发展现状来看,河南省普通高校高水平运动队存在运动队规模相对较小、教练水平有待提高、管理机制不完善、训练条件不足以及比赛偏少等制约因素。因此,要不断加强教练员的培训及引进工作,完善教练员的激励机制、运动员的管理体制和竞赛机制,积极改善训练条件,从而促进普通高校高水平运动队的健康发展。
