The Effect of Length of Stay on Travelers' Perceived Satisfaction with Service Quality

SUMMARY

Consumer satisfaction related to service quality during the vacation experience is of paramount importance to the travel and tourism industry. This study tests empirically the effects the number of nights spent on a vacation have on the levels of satisfaction recent travelers report for three service aspects of the travel destination: perceived satisfaction with tourism service providers; perceived “freedom from defects” of tourism services; and perceived reasonableness of the cost of tourism services. Differentiation in satisfaction scores between “short-term visitors” (i.e., those who stayed from one to six nights) and “long-term visitors” (i.e., those who stayed seven or more nights) were examined. Significant differences between the two groups of visitors were present for (1) perceived satisfaction with industry professionals delivering the service experience at the travel destination, (2) perceived satisfaction with “freedom from defects” of the actual services at the destination, and (3) perceived reasonableness of the cost of services at the travel destination. Suggestions for how tourism industry professionals can make use of this information are presented.     

页岩气水平井最优长度研究

页岩气作为一种新兴能源,得到国家与各个能源公司的重视。我国页岩气资源十分丰富,但是我国的页岩气勘探开发刚刚起步。目前广泛采用水平井开发页岩气藏,采用较大的水平段长度可以获得较高的采收率和较大的采油速度,但成本必然相应地增加,采用较小的水平段长度,可以降低成本,但会影响采油速度和最终采收率。由此看来,对于某一具体的水平井,必然存在一个合理水平段长度。本文从采油工程的角度研究页岩气水平井段最优长度的确定方法。

气候与贸易交叉议题的国际法规制

在国际法总体从碎片化向共进化的发展进程中,应对气候变化的国际法和促进自由贸易的国际法正自成体系地平行发展。同时,这两套国际法体系由于机制原因而产生包括碳贸易机制和单边减排措施在内的规则上的交叉议题。这些议题交叉现象虽非不可调和的冲突,但自2010年以来频繁爆发的气候与贸易争端案件,已使气候与贸易国际法规则的适用面临困境,短期内可通过世贸组织争端解决机制经由司法造法进程逐步解决气候与贸易议题交叉的规则适用问题。     

Austrian persistence? Capital-based business cycle theory and the dynamics of investment spending

Survey data are used to investigate the very long spending lags estimated in neoclassical studies of investment expenditures. Neoclassical investment theory has trouble explaining the length of these lags. By recognizing the Austrian concept of the capital structure and applying it to the problem, the present paper explains the length of these lags as proceeding from interactions between types of capital. Austrian arguments stemming from Austrian business-cycle theory seem to be needed to explain these lags. JEL Code E3, E4, C1

Exchange rate management in emerging markets: Intervention via an electronic limit order book

This paper describes and analyzes the implementation of a crawling exchange rate band on an electronic trading platform. The placement of limit orders at the central bank's target rate serves as a credible policy statement that may coordinate beliefs of market participants. We find for our sample that intervention increases exchange rate volatility (and spread) for the next minutes but that intervention days show a lower degree of volatility (and spread) than non-intervention days. We also show for intraday data that the price impact of interbank order flow is smaller on intervention days than on non-intervention days. These stabilizing effects, however, rely on the conditions of large currency reserves and the existence of capital controls; an electronic market seems to support this goal.     

论废弃物越境转移的法律规制

尽管我国已基本形成控制固体废物和危险废物进口的法律体系,但目前进口废旧物资的管理体制仍存在不少缺陷。由于废物利用、拆解等方面存在法律空白,每年有大量废物采用规避的办法进入我国。禁止危险废物进口,需要制定严格的法律文件,同时也要保证这些法律得到执行和遵守。提高人们的环保意识,发展和引进处理危险废物的科学技术,也是解决问题的有效途径。     

在计算机中解线性方程组的一种算法

本文直接根据行列式的定义，用QBASIC语言给出了计算行列式的算法。在运算过程中，只使用了乘法及加法运算，避免了因除法运算带来的计算误差，特别是行列式中的元素为整数并且计算结果是8位以下的整数时则完全没有误差，再使用克莱姆法则能求出线性方程组非常精确的解。     

Regression Sampling in Statistical Auditing: A Practical Survey and Evaluation

Several confidence intervals for the regression estimator are surveyed. A Monte Carlo experiment, based on the NETER and LOEBBECKE (1975) populations, gives estimated coverages and lengths of the different confidence intervals. One interval is exact under the assumption of multivariate normal distributions; it gives longer intervals (hence better coverages) than the interval based on a popular variance estimator. An interval due to ROBERTS (1970) is much too long. Jackknifing gives robust intervals. Rules of thumb for practitioners are given.
