抓好速度耐力,突出强度,提高密度——高校中长跑训练方式之谈

高校进行中长跑训练是高校办高水平运动队的产物,运动员以在校大学生为主,运动员一边学习一边训练,属于＂边学边训性＂,运动训练具有较强的业余性。这一特点决定了高校运动队不能采用专业队的训练方法和标准,而应立足于自身的现实条件,去寻找适合自己的训练方法。高校中长跑项目的教学、训练应结合高校体育教育的特点,抓好速度耐力,突出专项,突出强度,提高密度,对运动员运动成绩的提高效果比较理想。     

中国区域经济差距研究综述

近年来中国东、中、西部地区经济差距有逐渐扩大的趋势,再次引起了政府和学术界的关注。中央在十八大明确提出要实施全国经济协调发展战略,让不同地区的人民都能实现中国梦。实现中国梦的第一前提是公平。而区域差距的扩大显然有违公平原则,在这个大背景下,缩小区域差距便成为中国当前时期一个亟待解决的艰巨任务。参考大量国内外研究区域经济差距的重要文献,按照逐步深入的顺序,从区域经济差距的研究方法到中国区域差距度量和变化趋势,再到中国区域经济差距的成因和对策,依次进行概括总结,并进行了相关评述,提出了一个缩小区域差距的新思路,作为下一步研究的重点方向。

2＋1教学模式转变下思政课教法改革思考

思政课在高职院校的教学中与本科院校的教学特点不同,在高职院校培养“应用型人才”的目标下,2＋1教学模式的转变是整体的趋势,在2＋1教学模式下,思政课教学可以分为理论教学与实践教学两个部分,在理论教学中可以采用启发式教学法、讨论式教学法、辩论式教学法、案例式教学法、演讲式教学法、角色互挟式教学法、专题式教学法;在实践教学中可以采用实地考察法、社会调查法、工作实践法,从而提高教学的实际效果。     

顺应理论下的翻译策略与方法——以《红楼梦》杨宪益英译本为例

Verschueren的顺应理论为从语用学的角度研究翻译提供了新的理论框架。翻译策略和方法的选择应该分别实现对宏观交际语境和微观语言语境的动态顺应。归化和异化是实现动态顺应的翻译策略,直译和意译则是翻译方法。《红楼梦》的杨宪益译本为顺应论视角下翻译策略和方法的成功选择提供了例证。     

关注“90后”大学生思想特点创新高校思想政治教育方法

＂90后＂是当前大学生的主体,因成长环境的不同造成了其身上具有不同于70、80年代大学生的特性,这给高校思想政治教育带来了现实的挑战。思想政治教育者应根据＂90后＂的思想特点,创新思想政治教育方法,增强思想政治教育的针对性和实效性。     

Detecting Abnormal Bid-Ask Spread: A Comparison of Event Study Methods

This study examines empirical issues associated with the use of bid-ask spreads in event studies. The simulation results indicate that the distribution of average standardized abnormal spread shows little deviation from normality. Simulation results also indicate that the widely used percent spread metric results in test statistics with low power. In contrast, use of a standardized raw spread metric and a simple mean-adjusted expectation model results in well specified and reasonably powerful Patell and Brown-Warner type test statistics. As the abnormal spread series is characterized by high first order serial correlation, it is important to adjust for this serial correlation when using multi-day event windows.     

Does a “survival-by-exporting” effect for SMEs exist?

The trade literature has long discussed the existence of some benefits attributed to exporting (learning-by-exporting), among others, the improvement in survival chances. This paper examines whether exporting SMEs enjoy better survival prospects than non-exporting SMEs. We investigate the determinants of survival of exporting and non-exporting SMEs and explore whether the exporting behaviour plays a significant role in explaining their probability of exit. For this purpose, we estimate discrete time proportional hazard models that account for unobserved individual heterogeneity. The dataset is a sample of Spanish manufacturing SMEs drawn from the Encuesta sobre Estrategias Empresariales (ESEE) for 1990–2002. After controlling for firm, industry and economy characteristics, we find evidence supporting the existence of a sizeable “surviving-by-exporting” effect. That is, exporting SMEs face a significantly lower probability of failure than non-exporters.     

Repeated Dichotomous Choice Formats for Elicitation of Willingness to Pay: Simultaneous Estimation and Anchoring Effect

Repeated dichotomous choice contingent valuation data are generated from responses to a succession of binary questions regarding alternative prices for an environmental good. In this paper we propose a simultaneous equation model that allows for endogeneity and error correlation across the responses at each stage of the bidding process. The model allows us to study the evolution of anchoring effects after the second dichotomous choice question. Estimation involves the Bayesian techniques of Gibbs sampling and data augmentation, and the application focuses on the preservation value of a natural area. The results for a data set involving up to four successive dichotomous choice questions show that restricted multiple-bounded models are rejected by the data with the general model. In addition, willingness to pay tends to stabilize after the second stage in the elicitation process for the general unrestricted model. When taking anchoring effects into consideration, it is revealed that individuals’ responses in the latter stages are influenced by the sequence of bid prices offered in earlier questions. Nevertheless, they do not have a significant effect on welfare estimates.
