货币虚拟化进程的历史考证

货币虚拟化是适应社会、经济发展和科技进步的产物。当前，在经历了胚胎阶段、潜在可能阶段、夺取主导地位等阶段的演变后，货币虚拟化体现出了新的发展趋势——网络虚拟化货币。通过货币虚拟化进程的历史考证，对加深货币本质、货币虚拟化实践动因和金融虚拟化的理解有重要启示作用。     

A study of critical factors of the job involvement for hotel employees—Taking hotels in Taiwan as an example

The selection of staff is always a critical success factor for managers in the hospitality service sector. This work focuses on the front-line employees and supervisors of international tourist hotels as the study subjects to explore the direct effects of the individual guanxi networks and POS (perceived organizational support) of hotel staff on their job involvement, and examines the indirect effects of these via personality characteristics. For this paper, questionnaire surveys were utilized; 246 questionnaires returned, of which 221 were deemed valid samples appropriate for further analysis. Reliability analysis, EFA, CFA, and SEM were used to examine the data.     

一种改进的基于EMD分解的超宽带信号消噪算法

针对低信噪比超宽带信号的消噪问题，提出一种改进的基于经验模式分解（EMD）的 消噪算法。该算法首先对含噪信号进行EMD分解，得到多个固有模态函数（IMF）分量，然后 选取高阶IMF重构原信号，达到消噪的目的。针对对UWB信号的IMF重构过程中阶数阈值难以 确定的问题，通过数值仿真的方法，得到信号分量和噪声分量在不同阶IMF上的能量分布特 性；在对所得特性进行分析的基础上，设计了一种数据自适应的阶数阈值选取算法，解决了 EMD消噪中的阶数阈值选取问题。仿真结果表明，EMD消噪算法能够在较低信噪比下提供平均 10 dB的信噪比增益，可以有效地对超宽带信号进行消噪。     

木钉墙在红粘土基坑支护中的应用

在基坑工程完成后,锚喷支护等临时围护结构都被掩埋在地下,形成地下空间垃圾的同时,影响临近地下空间开发利用。文章尝试用松木钉代替锚杆在浅基坑施工中作为临时支护结构,通过用MIDAS GTS4.0有限元三维模拟计算后,在工程中成功运用,取得不错的经济、社会效果。

论接续犯的认定

接续犯属于实质的一罪,而连续犯属于实质的数罪。二者区别的关键在于数个危害行为在时间上的密接性程度。在理解接续犯的既遂形态时,应当将数个危害行为作为一个整体。     

The influence of place attachment on the relationship between destination attractiveness and environmentally responsible behavior for island tourism in Penghu,Taiwan

This study examines the causal relationships between place attachment, destination attractiveness and environmentally responsible behavior (ERB), and the mediating effect of place attachment. Four hundred and thirteen tourists were surveyed who had visited the Penghu islands, Taiwan. Structural Equation Modeling was used to determine the relationships among the variables and the mediating effects. Results show that the emotions and feelings (place attachment), which tourists have for Penghu, are positively associated with stronger ERB; the extent of attractiveness of island tourism as perceived by tourists is also positively associated with stronger ERB. A higher level of tourists’ destination attractiveness in regard to island tourism is associated with stronger place attachment; place attachment was found to exert a significant effect in mediating the relationship between destination attractiveness and ERB. The study shows that when island tourists are attracted by and are attached to the destination, they are more likely to exhibit ERB. The study pioneers the integration of all three factors in a sustainable tourism behavior model designed for tourists who stay one night or more at a destination, and tests the hypotheses for the first time in an Asian destination. Management implications and recommendations for the sustainable development of Penghu islands tourism are provided.     

Information, incentives and multinational firms

I present a model that explains a multinational firm's choice of organizational form. If a firm in the developed country outsources the production of its intermediate goods to a supplier in the developing country, it faces an adverse selection problem. If it chooses to produce the intermediate goods in its own subsidiary in the developing country, it faces an inefficient monitoring problem. My analysis of this tradeoff provides a new explanation for the observation that FDI is concentrated in capital intensive industries and yields two empirical hypotheses: more firms should adopt outsourcing instead of FDI after trade liberalization; the share of intra-firm trade in total trade should be increasing in the degree of productivity dispersion across intermediate goods suppliers in the developing country.
