公路工程施工项目特殊季节与夜间施工安全控制要点

由于公路工程施工项目多数属于点多线长、露天和连续作业,涉及的人员、材料、机械设备多,技术含量低且需要经常变换工种的施工环境,使得安全风险大,因此,各施工单位必须对夜间和季节性施工安全措施高度重视,针对夜间施工和未来特殊气候环境影响下施工中可能发生的造成人员伤亡、疾病、财产损失、工作环境破坏等危险及紧急情况,采取有针对性的事先预防措施。     

Free-play impact by customer segment

Little is known about the effectiveness of casino free-play campaigns, despite hundreds of millions of dollars in annual redemptions. These costly play incentives are awarded to individual players, based largely on management’s evaluation of their historical play. Extant campaign-level research suggests these incentives may not be effective in driving spend per visit, but there has been no attempt to examine efficacy across player tiers (e.g., light, medium, and heavy users). Analysis of 365 days of performance data from a Las Vegas Strip casino produced varied results across tiers, but all tier-level findings indicated a failure to recover the face value of the free-play incentives. While no support was garnered for the house money effect, the results were consistent with the notion of loss aversion. The methodological approach outlined herein provides the means to critically evaluate free-play offers at the tier level, fast-tracking campaign optimization via more targeted revisions.     

Does Money Matter in Shaping Domestic Business Cycles? An International Investigation

We study the contribution of money to business‐cycle fluctuations in the United States, the United Kingdom, Japan, and the euro area using a small‐scale structural monetary business cycle model. Constrained likelihood‐based estimates of the parameters are provided and time instabilities analyzed. Real balances are statistically important for output and inflation fluctuations. Their contribution changes over time. Models giving money no role provide a distorted representation of the sources of cyclical fluctuations, of the transmission of shocks, and of the events of the last 40 years.     

Developing a better understanding of the complexities of visitor loyalty to Karijini National Park,Western Australia

Visitor loyalty is essential for the future of parks; however our knowledge of it is poor and confounded by conceptualisation and measurement issues with loyalty often considered a single construct. Furthermore, previous research has focussed on loyalty to a single destination rather than loyalty to a park system. This paper analyses the loyalty intentions of visitors to Karijini National Park, Western Australia. Relationships between loyalty measures to this park and to parks generally are explored. Rather than a single construct, loyalty was evidenced by three dimensions within an increasing hierarchy of effort – a) visiting another park, b) referring and recommending, and c) advocating, paying, volunteering, and visiting again. Visitors who wanted access to friendly, helpful rangers were more likely to undertake loyalty behaviours requiring greater effort. Further refining loyalty's multiple dimensions is an important focus for future research complemented by recent efforts to match loyalty measures with actual visiting behaviour.     

Counterfeiting as Private Money in Mechanism Design

We describe counterfeiting activity as the issuance of private money, one that is difficult to monitor. Our approach, which amends the basic random‐matching model of money in mechanism design, allows a tractable welfare analysis of currency competition. We show that it is not efficient to eliminate counterfeiting activity completely. We do not appeal to lottery devices, and we argue that this is consistent with imperfect monitoring.     

货币信用属性演化的历史与逻辑

通过讨论主要货币起源与演化理论的矛盾与不足,从货币取得人们信任的角度,尝试整合了货币起源与演化的事实与逻辑,由此可以认为货币的本质是信用,(商品、金属)货币和纸币一样都是信用货币,货币演化是货币内涵的威权因素和物的因素相互竞争的结果;且货币制度的核心是信用。维持人们对货币的信心与币值稳定应当是任何货币调控的出发点和归宿。     

The implications of monetary expansion in China for the US dollar

We examine the influence of rapid growth in China's money supply on the US dollar within a framework of monetary models of exchange rates. We develop out-of-sample forecasts of the US dollar exchange rate using US and global data on price level, output, and interest rates, and money supply data for the US, China, and the rest of the world for the period 1996–2013. Monetary model forecasts significantly outperform a random walk forecast in terms of mean squared forecast error in the long run. A monetary error correction model with sticky prices performs best. Rolling sample analysis indicates changes over time in the influence of Chinese money supply in forecasting the US dollar. The expectation is that rapid money growth in China would increase the demand for dollars thus raising the value of the dollar, yet our forecasts are to the contrary for the mid 2000s. This is consistent with anticipation of renminbi appreciation under China’s managed exchange rate, which made holding renminbi more attractive. With the break from a dollar peg in 2005 and subsequent currency appreciation, the distortion was alleviated and the forecast direction for the dollar became as expected.

洗钱罪刑事立法之完善——以《联合国反腐败公约》为视角

《联合国反腐败公约》对洗钱犯罪作了规定,我国现行《刑法》对洗钱罪的规定与《公约》存在较大差异,从而使我国对洗钱罪及其上游犯罪的预防和打击的效果受到影响。我们有必要根据《公约》的规定完善我国关于洗钱犯罪的立法。
