概念迁移视阈下基于语料库的非英语专业学习者动名词搭配错误研究

文章拟从概念迁移视角研究大学英语写作中的动-名词搭配错误,研究采用语料库定量与定性相结合的分析方法。语料取材于中国学习者英语语料库（CLEC）,包括大学英语低年级学习者（St3）和高年级学习者（St4）两个子语料库。利用检索工具Ant Conc3.58检索中国学习者作文中的动-名词搭配错误,从而对大学生英语写作中的动-名词搭配错误进行描述与分类,进而分析造成大学生英语写作动-名词搭配误用的潜在原因,并对现有大学英语教学做出反思。     

Industry and the environment: a case study of cleaner technologies in selected European countries

The aim of this case study is to discuss the role of technology in addressing environmental problems. The paper tries to scratch beneath the surface of the increasingly frequent ‘quick-fix’ solutions to the present environmental problems, based on such beguiling catchwords as Cleaner Technologies, Best Available Technologies, and Best Available Technologies Not Exceeding Excessive Costs, etc., in an attempt to discover whether there is any substance in them, or whether they are just full of hot air. Recent data from case studies performed by the author in Germany and Finland as well as a postal questionnaire in Denmark are presented. The paper analyses and discusses the roles and responsibilities of designers, industrialists, and government policy-makers. It is argued that existing regulatory regimes, supranational industrial structures, and market mechanisms do not favour the development of cleaner technologies, nor do they promote a reduction in consumption patterns. Evidence from ongoing empirical research in Northwest Europe suggests that industry is far from developing and/or implementing cleaner technologies. The paper closes with a discussion of some of the policy implications involved and some examples of urgently needed further research.     

Female labor force participation in the US: How is immigration shaping recent trends?

Women entered the paid workforce in unprecedented numbers during the 20th century. Yet recent years have been witness to a creeping reversal in women's labor force participation. Why did the revolution stall? In response to debates over a “natural” limit to women's employment, or a cultural backlash against the dual-breadwinner household, we consider an alternative explanation, namely whether immigration has slowed the growth in female labor force participation. Using CPS data from 1998 to 2018, we show that the increase in the share of immigrants and children of immigrants in the population has reduced overall female labor force participation. However, immigration accounts for relatively little of the retreat from the labor force. Instead, the compositional effect of population change is overshadowed by behavioral shifts that affect both natives and immigrants. Lower participation rates among native-born women accounts for most of the overall decline. Despite persistent differences, we also find substantial convergence in the labor force behavior of native-born and foreign-born women, which bodes well for the long-term economic incorporation of immigrants and their children.     

The internal relocation premium: are migrants positively or negatively selected? Evidence from Italy

This paper analyzes the wage returns from internal migration for recent graduates in Italy. We employ a switching regression model that accounts for the endogeneity of the individual's choice to relocate to get a job after graduation: the omission of this selection decision can lead to biased estimates, as there is potential correlation between earnings and unobserved traits, exerting an influence on the decision to migrate. The empirical results sustain the appropriateness of the estimation technique and show that there is a significant pay gap between migrants and non-migrants; migrants seem to be positively selected and the migration premium is downward biased through OLS estimates. The endogeneity of migration shows up both as a negative intercept effect and as a positive slope effect, the second being larger than the first: bad knowledge of the local labor market and financial constraints lead migrants to accept a low basic wage but, due to relevant returns to their characteristics, they finally obtain a higher wage than the others.

最低工资标准与和谐劳动关系的构建——广州、佛山、深圳最低工资标准比较研究

最低工资保障问题是构建和谐劳动关系的核心内容和难点问题。对广州、佛山和深圳最低工资标准现状进行分析,并运用ELES模型测算其最低工资标准,测算结果显示：目前三市最低工资实际标准与理论标准仍有差距,其中广州的差距最小,佛山次之,深圳的差距最大;最低工资标准与职工平均工资比例偏低,与人均GDP比例关系失调,深圳最低工资执行标准总体优于广州和佛山。鉴此,提出应以发展线水平为目标制定最低工资标准等建议。     

Arbeitsmarktforschung und Arbeitsmarktstatistik aus der Sicht der wirtschaftspolitischen Beratung: Erfahrungen und Perspektiven

Zusammenfassung: Dieser Beitrag beleuchtet aus der Sicht der wirtschaftspolitischen Beratung einige Anforderungen an die Arbeitsmarkt?konomik und Arbeitsmarktstatistik. Drei Bereiche werden angesprochen: die Arbeitslosenstatistik, die Tariflohnpolitik und die aktive Arbeitsmarktpolitik. Dabei werden zun?chst die Bemühungen hinsichtlich einer realistischeren Erfassung der Unterbesch?ftigung gewürdigt, zugleich aber Hinweise auf Verbesserungsm?glichkeiten gegeben. Anforderungen an die amtliche Statistik ergeben sich des Weiteren hinsichtlich der Tarifentgelte. In diesem Zusammenhang wird die Umsetzung der Erkenntnisse der Arbeitsmarkt?konomik in eine lohnpolitische Orientierungshilfe skizziert. Schlie?lich erfolgt eine kritische Einsch?tzung des Erfolgs der aktiven Arbeitsmarktpolitik, wobei eine zunehmende Willigkeit zur Bereitstellung der für die Evaluation erforderlichen Daten konstatiert werden kann.

Summary: This paper deals with three demands on labor economics and labor statistics put forward from the point of view of an advisor to economic policy. Despite several improvements of unemployment statistics, a lot of work remains to be done. With respect to wage policy attempts by the German Council of Economic Experts are discussed how to formulate a guidance for wage policy both on scientific grounds and understandable by the public. Finally, a critical assessment of active labor market policies is presented together with a plea for adequate individual data in order to carry out a sound evaluation of these policies.

产业转移:承接地之间竞争的博弈研究——以皖江城市带为例

由于具有相似的区位条件和产业结构,并处在大体相同的发展阶段,皖江城市带各市在承接产业转移上势必会产生激烈的竞争。鉴于此,文章通过构建比较优势和政府政策的两城市承接产业转移博弈模型,得出具有比较优势的城市将获得更高的收益、城市之间的合作比不合作将带来更高的收益等结论,在此基础上,提出应发挥自身优势承接产业转移,建立合理的分工协作机制,避免恶性竞争,引导产业向皖江城市带聚集等措施。
