IntroductionChina’s accession to the World Trade Organization (WTO) on 11 December 2001 was a monumental event. Never has an accession to the WTO stirred up such intense emotions throughout the world: euphoria, envies, and, above all, fears. Workers on both sides of the Pacific Ocean and beyond have genuine fears of losing their jobs. Governments and entrepreneurs from both developing and developed countries are afraid of展开更多

The artisanal gold mining communities were studied using secondary data from scholarly articles and journals, books, conference papers, research reports, policy documents, working papers, and briefs. Descriptive and systematic analyses were conducted. The result indicated that youth aged between 21 - 30 were most likely to engage in illegal mining operations in the selected study areas. The study revealed that farmland had been destroyed, making farming difficult for the inhabitants. It is evident from the review that dug-out pits from mining serve as breeding grounds for mosquitoes and death traps for humans. The study, therefore, accentuates the need for illegal small-scale gold mining to be formalised and strategic interventions and policies proposed for the protection of Ghana’s Natural resources. Furthermore, community members should be involved in policy-making and environmental protection issues to help control the menace of landscape destruction. Although the ban on illegal gold mining activity by the government has caused more people to lose their jobs leading to livelihood challenges in mining communities, it is a step in the right direction, as the ban seeks to halt and check the illegal small-scale mining sector. The study recommended alternative livelihood and income-generating projects such as beekeeping, mushroom culture, grasscutter rearing, and agroforestry technologies including the growth of economic fruit trees as alternative livelihood ventures.展开更多

The Manuscripts was important works of Marx, in which the social relations of capitalism private ownership were analyzed by Marx using the concept of alienated labor. A deep analysis was conducted by Marx from the specific historical facts, in which the rational kernel of the alienated problem in the social relations of capitalism was mentioned. Specifically, the alienated labor theory was analyzed from the relationship of laborers with their labor products and labor itself, human＇ s essence, and other people under the condition of the capitalist private ownership; the ＂ought to be＂ ethical characteristics of labors were expounded from the perspective of ethics, and the abnormal labor relations in the process of capitalist production were ethically reviewed and criticized. Therefore, rich economic ethics thoughts were contained in Marx＇ s analysis of the alienated labor theory.展开更多

文摘For the capital market satisfying standard assumptions that are widely adopted in the equilibrium analysis,a necessary and sufficient condition for the existence and uniqueness of a nonnegative equilibrium price vector that clears the mean-variance capital market with short sale allowed is derived.Moreover,the given explicit formula for the equilibrium price shows clearly the relationship between prices of assets and statistical properties of the rate of return on assets,the desired rates of return of individual investors as well as other economic quantities.The economic implication of the derived condition is briefly discussed.These results improve the available results about the equilibrium analysis of the mean-variance market.
