浅谈独立学院大学英语听力教学

英语听力是英语综合能力的一个重要方面,也是英语教学的重要环节之一。本文就独立学院中大学英语的教学现状和学生的学习现状,分析出其存在的问题并提出相关的教学应用策略。     

美国港口发展模式及对我国的启示

美国作为世界贸易大国，其港口管理体制和发展战略也有它的独到之处，360多个公共和私人码头在美国经济发展中起着引擎的作用。在港口的运作中，涉及立法、政府管理机构、港务局、码头经营商等多重主体。美国近年来在港口管理的各个方面均加速了制度创新、管理创新和技术创新，其经验值得我们学习借鉴。

旅游业在海口市国民经济中具有重要贡献,循环经济对于海口市这样一个既需要促进经济高速增长而资源又相对稀缺的海岛型城市的发展具有重要的指导意义。海口市旅游业循环经济建设不能只是市场和国家的结合,必须是包括社区在内的三个组织的结合。     

The impact of microcredit on self‐employment profits in Vietnam

This study examines the impact of microcredit on household self‐employment profits in Vietnam. For two indicators of credit participation – a dichotomous participation dummy and the accumulated amount of microcredit received per household – the analysis reveals a positive effect on household profits. The analysis also reveals that an instrumental variable method within a fixed‐effects framework can control for the possible endogeneity of credit and thereby identify the true effect of credit.     

Flexible Estimation of Copulas: An Application to the US Housing Crisis

Zimmer (‘The role of copulas in the housing crisis’, Review of Economics and Statistics 2012; 94 : 607–620) provides an interesting case study of the pitfalls of using parametric copulas to understand the US housing crisis in the latter part of 2000s. The original study by Zimmer (2012) employs a finite‐mixture copula to illustrate that the symmetry of the Gaussian copula may not be tenable, especially for US housing price data during the time period from 1975:Q2 to 2009:Q1. We undertake a replication of his study in a wide sense. First, we replicate the study by incorporating revised data and then extending the dataset to include the most recent data. Second, we implement a nonparametric copula estimator recently proposed by Racine (‘Mixed data kernel copulas’, Empirical Economics forthcoming) to the parametrically filtered data used in Zimmer (2012). Our replication finds that the application of the nonparametric copula to the same and extended filtered data provides an alternative flexible specification for copulas. However, the overall cautionary message of the flexible‐form copula espoused in Zimmer (2012) remains. Copyright © 2015 John Wiley & Sons, Ltd.     

Is the quality of female auditors really better? Evidence based on the Chinese A-share market

Unlike previous studies in which a single index was used to measure audit quality, this study establishes a new comprehensive index to measure audit quality via Discretionary Accrual, as estimated by Jones’ basic model (1991) and Audit Opinions. The former is used to measure the quality of financial statements, and the latter is used to measure the auditors’ independence in the mainstream international literature. We examine whether and how an auditor’s gender affects the quality of his or her audits under the framework of empathy theory and gender role socialization theory. Using a large sample of 9861 auditor-firm-year observations from Chinese A-share–listed companies from 2011 to 2015, we find that the audit quality of signed auditors shows significant gender differences: these significant gender differences differ from the findings of previous studies that female auditors could provide a higher-quality audit than male auditors; that is, in our study the audit quality of the male auditors exceeds that of the female auditors. After distinguishing the positive and negative directions of the Discretionary Accrual, we find no significant gender differences in audit quality between male and female auditors when the earnings had been adjusted upward by the client; that is, female and male auditors had the same audit risk perception. However, when the client adjusted earnings downward, which indicates a lower audit risk for the auditor, the audit quality of female auditors was significantly lower than that of the male auditors. After controlling for the age and position of the auditors, we also find that the gender differences in the auditors’ audit quality decreased significantly or even disappeared when the auditor’s age exceeded 45?years and/or their position was manager or above. These results are consistent with the empathy theory and gender role socialization theory.     

What Causes Banking Crises? An Empirical Investigation for the World Economy

We add the Bernanke-Gertler-Gilchrist model to a world model consisting of the US, the Euro-zone and the Rest of the World in order to explore the causes of the banking crisis. We test the model against linear-detrended data and reestimate it by indirect inference; the resulting model passes the Wald test only on outputs in the two countries. We then extract the model’s implied residuals on unfiltered data to replicate how the model predicts the crisis. Banking shocks worsen the crisis but ‘traditional’ shocks explain the bulk of the crisis; the non-stationarity of the productivity shocks plays a key role. Crises occur when there is a ‘run’ of bad shocks; based on this sample Great Recessions occur on average once every quarter century. Financial shocks on their own, even when extreme, do not cause crises—provided the government acts swiftly to counteract such a shock as happened in this sample.
