填筑土体压实度快速检测试验

针对平原水库围坝填筑压实度快速检测做了大量的"三点击实"和标准击实试验。分析了三点击实试验过程中减水情况及加、减水情况下试验方法的可行性及其数据合理性,和标准击实试验方法进行了比较,认为减水情况及加、减水情况下试验方法是可行的,在减水情况下最优含水率和填土含水率的差值一般在-3%～0,同时试验过程中土体减水率小于6%时,三点击实试验成果比较合理。用三点击实试验方法填筑土体压实度所用时间比标准击实试验的方法省6～8h,三点击实试验填筑土体压实度的方法针对土体特性差别较大的工程中适用性强。提出了减水情况下的三点击实试验步骤及试验过程中的注意事项。     

论各类失业的结构性质--对西方失业理论的另一种思考

从理论上说失业有很多类型。产业结构调整和升级背景下的失业原因也是多方面的。本文通过对各种失业理论的分析比较 ,认为通常所说的“结构性失业”不足以涵盖产业结构变化中的失业现象 ,现实情况下 ,“混合失业”、“自然失业”、“隐性失业”等都带有结构性质 ,都与产业结构的变化有密切的联系     

中国经济转型时期商业银行信贷退出问题研究

信贷退出要遵循两个基本原则:一是风险—收益对称原则,二是成本—收益均衡原则。退出成本最低、收益最大、能够较好地掌控风险的时期是信贷退出的最佳时机。判断何时为最佳退出时机必须准确把握行业经济周期、产业结构演进规律、企业生命周期、产品生命周期以及企业信用等级和财务等相关指标的变化。商业银行应该根据信贷进入的行业、区域、企业以及信贷产品制定相应的退出策略。信贷退出路径包括直接退出和间接退出,商业银行应首先考虑间接退出。商业银行信贷退出机制的构建主要包括转换观念,建立行业信贷分析预警退出机制、区域信贷退出机制、客户退出机制、信贷退出激励约束机制等内容。

中国企业技术创新成功的环境条件分析

企业技术创新成功的环境条件分为四个不同的层次和五个不同的维度。由于我国企业环境建设不系统,因此我国企业没有成为技术创新的主体。正确认识我国企业技术创新环境问题是十分必要的。     

翻译策略的制定与文化诉求的伸张

翻译通过语言的转换实现文化的跨越,前者是手段,后者才是目的。在此过程中,译者采取何种翻译态度和模式,往往与其文化诉求有关联,并且这种文化诉求不仅关乎译者个人的文化素养、价值取向、意识形态,还关乎历史的、政治的、宗教的背景。因此,翻译的过程是一个语言转换的过程,更是借助特定翻译策略表达某种文化诉求的过程。     

Use numbers not words! Communicating hotels’ cleaning programs for COVID-19 from the brand perspective

After hotels in many countries were forced to close in government-imposed lockdowns during the COVID-19 pandemic, there is an inherent need to communicate how they deal with the coronavirus to motivate guests to visit. However, lack of knowledge about how to persuasively communicate about hotels’ cleaning programs for COVID-19 can challenge the industry’s survival. We investigated how hotels that position their brand as a particular personality (sincere vs. exciting) could benefit from different communication styles (inclusion of numerical vs. verbal quantifiers) when presenting their COVID-19 cleaning procedures. Study 1 explored tourists’ central attitudinal responses toward hotels’ cleaning programs. Study 2 demonstrated that sincere hotel brands would benefit from using numerical and verbal quantifiers to communicate their cleaning policies, whereas exciting hotel brands would benefit only from numerical quantifiers. Our results invite hotel managers to use their brand personality positioning to influence tourists’ attitudes and intentions in a pandemic context.

The Rocky Road to Legacy: Lessons from the 2010 FIFA World Cup South Africa Stadium Program

This article describes how the management and organization of the South African 2010 FIFA World Cup stadium program shaped the current legacy of an oversupply of overdesigned and underutilized stadiums. The article identifies seven key factors that explain the differences between expected benefits and the actual legacy. Identification of these factors contributes to the increasing academic interest in explaining the poor legacy outcomes of mega‐events. In conclusion, we recommend that future host country governments defragment their stadium programs by establishing a World Cup Delivery Authority (WCDA), with responsibility for the leadership and coordination of the stadium program.     

Does participation in the sloping land conversion program reduce the sensitivity of Chinese farmers to climate change?

Over the last two decades, extensive literature has examined the socioeconomic and environmental impacts of China's Sloping Land Conversion Program (SLCP), a program that was launched in late 1990s to mitigate the environmental effects of agricultural production and reduce rural poverty. However, little empirical evidence exists with regard to the impact of SLCP on rural households' sensitivity to nature-induced changes and environmental challenges. In this study, household-level data covering the period 1995–2010 from five Chinese provinces were used to examine the effect of SLCP on farmers' sensitivity to climate change. The empirical results show that participation in SLCP significantly reduced farmers' sensitivity to climate change by reducing their dependency on land and natural resources for income, and by diversifying their livelihood options. Spatially, the results reveal that the effect of SLCP on farmers' sensitivity vary across regions. Specifically, SLCP was found to have a ‘rate effect’ on farmers in the Northern regions and a ‘level effect’ on farmers in the Southern regions. Likewise, we found that the effect of SLCP differs considerably across income groups, with the effect on low- and middle-income groups being most significant. The results indicate that subsidy is the main pathway through which SLCP reduces farmers' sensitivity to climate change. In contrast, we found inclusive evidence about the indirect effect of SLCP farmers' sensitivity through the promotion of non-agricultural employment. These results carry major implications with regard to the effectiveness of ecological conservation programs and their mitigation potential through building farmers' resilience in China and ecologically fragile environments.
