欧盟关于人员自由流动的立法特点及其启示

欧洲联盟内部人员自由流动,同商品、服务和资本的自由流动一起,构成了欧洲经济一体化的基本内容.人员在成员国之间自由流动,直接冲击成员国现行的经济、社会等制度,因此往往遭遇障碍和歧视.欧盟从建立时起,就注重对人员自由流动的法律调整,并形成了自己鲜明的立法特点.我国正处于城市化的高潮时期,人员流动正迅速发展.我们应该借鉴欧盟的经验,加强人员流动方面的立法,以确保人员流动有序进行,促进改革开放的健康、和谐发展.     

生产力、生产关系矛盾运动规律新探

生产力、生产关系辩证运动规律是人类社会发展变化的基本规律。长期以来,由于对这一基本规律认识的简单化和绝对化,造成了认识上的混乱。首先,生产力不是“物质力量”,而是人与自然的矛盾关系的统一;其次,生产力的存在方式是客观现实性和社会历史性的统一,与之对应,生产关系也是如此;再次,生产力、生产关系的矛盾运动规律不是“有什么样的生产力,就有什么样的生产关系”,而是生产力的质变必然导致生产关系的质变,生产力的量变也可能导致生产关系的质变,一种性质生产力的存在,可以决定不同性质生产关系同时并存。     

焦点和“没”字句的句法分析

焦点表示句子中强调的信息,它是语言学中引起广泛关注的课题之一,焦点结构和句法结构一样,是对句子结构的描写,表现了句子的信息分配形式。否定属于对焦点敏感的结构,是一个受焦点影响的现象。在汉语否定结构“没”字句中,“没”作为焦点敏感算子,其语义指向范围是全句。在句法层面,焦点短语作为整体移位,遵守孤岛限制。     

资本投入、劳动力转移和农业经济增长

土地、技术、劳动力是农业经济增长的决定因素。由于我国农村市场发育迟缓,导致获得外生农业技术的成本很高。这样,内生农业技术进步和劳动力的适时转移就成为影响农业经济增长的主要因素。同时,在二元经济结构下,农业劳动力的转移也会影响到非农部门的经济增长。因此,建立一个基于内生农业技术进步的二元经济增长模型可以用来解释农业经济增长的历史过程,评价农业政策的绩效和效率。     

农村合作运动与农业技术的植入——以民国时期江苏省为例(1927-1937)

农村合作运动是国民政府为发展农业生产、复兴农村经济、改善农民生活而实施的有关社会经济建设的行动。农村合作运动中组建的各种合作社,在改良品种、改进耕作技术、推广农业知识等方面发挥了重要的作用,扮演了引进和扩散现代农业生产要素的角色,丰富了作物的品种,提高了农业生产的效率,增加了农民收入。     

Co‐movements in commodity prices: a note based on network analysis

This article analyses co‐movements in a wide group of commodity prices during the time period 1992–2010. Our methodological approach is based on the correlation matrix and the networks inside. Through this approach we are able to summarize global interaction and interdependence, capturing the existing heterogeneity in the degrees of synchronization between commodity prices. Our results produce two main findings: (a) we do not observe a persistent increase in the degree of co‐movement of the commodity prices in our time sample, however from mid‐2008 to the end of 2009 co‐movements almost doubled when compared with the average correlation; (b) we observe three groups of commodities which have exhibited similar price dynamics (metals, oil and grains, and oilseeds) and which have increased their degree of co‐movement during the sampled period.     

The Power of Stakeholders' Voice: The Effects of Social Media Activism on Stock Markets

Building on social movement theory, this study assesses the influence of social media activism on the stock market performance of targeted firms. We focus on information published on Twitter by two critical stakeholders: consumer associations and trade unions. To the extent that social media represent a valid medium to mobilize stakeholders' activism, protests on Twitter may damage firm reputation, leading to capital market reactions. Using a corpus of over 1.5 million tweets referring to Spanish listed banks, we study the impact of activism by looking at targeted firms' abnormal variations in price and trading volume. Our findings suggest that the Twitter activism of key stakeholders has a significant impact on investors' decisions. Further, our empirical analyses indicate that the mechanisms affecting investors' behavior differ depending on the characteristics of the stakeholder group. Hence, this study contributes to understanding how social movements influence corporate behavior via social media. Copyright © 2017 John Wiley & Sons, Ltd and ERP Environment     

Accounting for the Business of Suffering: A Study of the Antebellum Richmond, Virginia, Slave Trade

When the Congress barred the importation of slaves into the United States in 1808, it left the internal slave trade intact. The trade took on a new importance as the slave states of the Old South saw their agricultural economies shift to a point that holding large numbers of slaves became too expensive. During this time, the large agricultural concerns shifted to the New South, where cotton and sugar plantations needed the cheap labour provided by the institution of slavery. As this transition intensified, Richmond, Virginia, became a central slave market that facilitated the interstate slave trade as Old South planters chose the course of selling slaves as a valuable commodity rather than the course of manumission. The records of two businesses—Dickinson & Hill and Hector Davis & Company—which plied the slave trade in the Richmond market, have survived into the twenty-first century. These records revealed a primitive, yet sophisticated, process to account for the consignment, purchase, and sales of human merchandise in this haunting story of the 'business of suffering'.
