粮食安全背景下主产区的现实困境和选择

在现阶段,跨国粮商已经做到了全球化经营、全环节利润、全市场覆盖的运作模式。那么,针对粮食主产区的现实困境,在保障我国粮食安全的同时,主产区实施粮食产地加工以促进自身发展渐成大气候,必将成为粮食主产区的现实选择。     

抓好大型商品粮基地建设提高粮食安全保障水平

粮食是人类生存与发展的基础。粮食安全是事关我国经济社会全局的战略性问题。在当前物价上涨压力较大的形势下,抓好粮食生产是确保实现“双防”目标的必然要求。山东是农业大省,也是全国重要的粮食主产区,抓好国家大型商品粮基地建设,改善粮食主产区生产条件,进一步增强粮食综合生产能力,对于保障国家粮食安全具有举足轻重的作用。

关于做强做大黑龙江省粮食流通骨干企业的战略思考

当前,国际粮食价格持续上涨,引发了全球性的粮食危机。迄今全球粮食储备量已减少到30年来的最低水平,给世界粮食安全笼罩上阴影。粮食安全是国家或地区经济安全的重要组成部分,黑龙江省作为全国粮食主产区,粮食流通领域暴露的问题日渐明显,从维护国家地方粮食安全的战略高度,应以改革创新的办法,做强做大地方粮食流通骨干企业,进而带动粮食主产区发展,促进农民增产增收,加快新农村建设步伐。     

从全局和战略高度抓好农业和粮食工作

近年来，我国粮食生产出现了一些新情况、新问题。耕地面积、粮食面积和粮食产量逐年下降。究其原因，当前种粮效益低、主产区农民增收困难的问题尤为突出。如何调动农民的种粮积极性，保护和提高主产区的粮食生产能力，是确保国家粮食安全、稳定国民经济大局的首要任务。自去年国务院农业和粮食工作会议后，各省、自治区、直辖     

加入WTO对东北地区粮食产业发展的影响及对策

Healthy Investments in Investing in Health

This article discusses socially responsible investing (SRI) and tobacco. SRI allows investors, both institutional and individual, to express their concerns and make their social and ethical stands known to the companies they invest in and patronize. The tobacco industry is active in every country on the globe and generates huge profits, while tobacco use is responsible for 4 million deaths every year.The authors explore past and current views on investment in tobacco, partly based on a survey conducted by the Tobacco Free Initiative of the World Health Organization (WHO). There is clearly a trend toward divestment from tobacco for both ethical and financial reasons. Tobacco-free investments can be both ethically sound and financially profitable.     

Developments in Consumer Protection in India

This paper surveys the major developments in the field of consumer protection in India since 1984, when the statutory provisions for regulating unfair trade practices were incorporated for the first time.Among the developments described in the paper is the strengthening of provisions for consumer protection through amendments to the Act regulating restrictive and monopolistic trade practices (the MTRP Act). Public-sector undertakings and co-operative societies have been brought within the purview of the Act, and consumers have obtained the right to participate in inquiry proceedings before the MRTP Commission.Consumers and their associations have been given the right to seek redress of grievances arising out of the violation of certain pieces of legislation, including the Drugs and Cosmetics Act. The Consumer Protection Act, 1986, was enacted in order to provide speedy and inexpensive redress of consumers' grievances. Redress can now be sought before any consumer court also for negligence or deficiency in medical services.The Bureau of Indian Standards Act, 1986, has strengthened the measures for the standardisation and quality control of manufactured goods.A Consumer Welfare Fund has been set up to provide financial assistance to voluntary consumer organisations and for the general development of consumer movement in the country. A spurt in voluntary consumer organisations in different parts of the country can also be observed.Other developments include the establishment of a separate Department of Consumer Affairs in the Union Government and the setting up of a Consumer Product Testing Laboratory.

Conflict in Supplier–Retailer Relationships in the Brewery Industry in Cameroon

The authors develop a theoretical framework to explain conflict in supplier–retailer relationships. In addition to traditional influence strategy variables, the framework links conflict to retailer dependence and supplier formalization. The framework is empirically tested in the Cameroonian brewery industry. The findings support the view that channel conflict is inversely related to retailer dependence and supplier formalization. Contrary to expectations, the use of noncoercive influence strategies (information exchange and recommendations) has no significant effect on conflict, while, as expected, the use of coercive influence strategies (threats and promises) increases conflict.

Recent advances in reinforcement learning in finance

The rapid changes in the finance industry due to the increasing amount of data have revolutionized the techniques on data processing and data analysis and brought new theoretical and computational challenges. In contrast to classical stochastic control theory and other analytical approaches for solving financial decision-making problems that heavily reply on model assumptions, new developments from reinforcement learning (RL) are able to make full use of the large amount of financial data with fewer model assumptions and to improve decisions in complex financial environments. This survey paper aims to review the recent developments and use of RL approaches in finance. We give an introduction to Markov decision processes, which is the setting for many of the commonly used RL approaches. Various algorithms are then introduced with a focus on value- and policy-based methods that do not require any model assumptions. Connections are made with neural networks to extend the framework to encompass deep RL algorithms. We then discuss in detail the application of these RL algorithms in a variety of decision-making problems in finance, including optimal execution, portfolio optimization, option pricing and hedging, market making, smart order routing, and robo-advising. Our survey concludes by pointing out a few possible future directions for research.
