冲泡条件对辣木茶中稀土浸出率的影响研究

本文采用ICP-MS方法测定辣木茶的稀土总量,以及不同冲泡条件下稀土的浸出率。实验结果表明,辣木茶的稀土浸出率随冲泡时间的延长而升高,且增长逐渐趋于平缓。此外,随冲泡次数的增加,样品的稀土浸出率基本上呈减小趋势。五次冲泡后辣木茶中稀土的累计浸出率为18.15%。虽然原茶中稀土含量较高,但由于稀土氧化物主要残留于茶渣中,总体上处于比较低的暴露水平,对饮茶人群的健康影响较低。

基于损失厌恶的开放式基金业绩激励研究

基于行为金融理论,建立了投资者表现为损失厌恶情形下的开放式基金业绩激励模型,并考察了投资者的损失厌恶偏差对开放式基金业绩激励效率的影响。结果表明:在开放式基金的业绩激励机制下,损失厌恶型投资者在面对失败的投资结果时会低估基金经理的投资管理能力,进而低估投资的期望收益;在一定条件下,与完全理性型投资者相比,损失厌恶型投资者会导致业绩激励效率损失增大。     

The exchange rate pass-through into import prices: the case of Japanese meat imports

Japan is a traditional net importer of food products in general and meat products in particular. Japanese meat imports come from a few countries thus making Japan potentially very sensitive to the swings in one or a few bilateral exchange rates. One of the key contributions of this article is the use of commodity (meats in this case) imports weighted exchange rates in the analysis. The standard practice in previous international agricultural trade studies related to either exchange rate pass-through or pricing to market was to use the aggregate trade weighted exchange rates usually provided by the Central Bank authorities or sources. Beef and poultry import prices indicate partial exchange rate pass-through while import prices of pork indicate zero exchange rate pass-through, primarily due to gate price policy system applied to pork imports. In terms of competitiveness, these results suggest relatively more competitive markets among poultry importing firms, somewhat competitive markets among beef importing firms, while competitiveness of pork importing firms could not be assessed due to existing import policies.     

"以农立国"还是"以工立国"——对1920-1940年代关于农村建设争论的评析

1920～1940年代中国知识界掀起了对农村建设的争论,在这场争论中也分成了若干派别,如“以农立国派”、“以工立国派”、“调和派”、“先农后工派”和“革新制度派”等。这场争论表明,对于中国社会转型时期的政治制度、经济制度的变革,要避免非此即彼的简单的二元化思维模式。同时,要将农村本身与宏大的经济体制和社会变迁连在一起进行深入的分析和探讨,体制问题是农村建设的根本。

互联网能力与知识能力交互效应对知识创造绩效的传导机制:一个被中介的调节效应模型

整合资源基础观、知识基础观和动态能力理论,探讨互联网背景下互联网能力、知识能力两种企业内部因素交互作用对知识创造绩效的影响过程,尤其关注了具有前瞻性与反应性特征的战略柔性在这一过程中的重要作用,从而构建了一个被中介的调节效应模型。基于我国399家企业调研数据发现,互联网能力、知识能力均对战略柔性有显著正向影响;互联网能力与知识能力的交互作用通过战略柔性的中介机制促进企业知识创造绩效提升,即存在被中介的调节效应。在理论上,丰富了资源基础观和知识基础观在组织竞争优势构建方面的前因研究,在实践上,为处于互联网背景下的企业有效提升知识创造绩效提供了实践参考。     

Case study in disaster relief: A descriptive analysis of agency partnerships in the aftermath of the January 12th, 2010 Haitian earthquake

This study analyzes the disaster response and recovery efforts following the January 12th, 2010 Haitian earthquake through the eyes of 18 different relief agencies. Focusing on the formation and maintenance of partnerships after the catastrophic earthquake, this paper explores the concepts of cooperation, mutual understanding, and connectivity among agencies responding to the earthquake. The case study is based on results from interviews and interactions with 18 agencies during a month-long trip to Haiti in the summer of 2010. Of the agencies interviewed, it was found that agencies that had no partnerships or presence in Haiti prior to the earthquake were most likely to build new clinics, orphanages, and schools. Additionally, we found that agencies were more likely to develop new partnerships from new contacts rather than dormant contacts. By studying the partnerships between local and international agencies, it was found that their relationships were less stable than partnerships between international agencies. This study hopes to increase understanding and applicability of research in disaster relief networks by providing a new perspective into how agencies work together.
