纳米VO2的制备及在智能控温包装材料中的应用

本文分别采用水热法和溶剂热法制备低维VO2（B）纳米材料,然后在N2（99．999％）氛围中将VO2（B）进行623K热处理,得到VO2（M）蓝黑色粉末。利用X-射线衍射（XRD）、X-射线光电子能谱（XPS）、红外光谱（FTIR）、透射电子显微镜（TEM）和高分辨力透射电子显微镜（HRTEM）等测试样品的成分及形貌特征。结果发现：水热法制得的VO2（B）经热处理后得到VO2（M）纳米带,该纳米带有数微米长,宽100～150nm,厚20～30nm,是典型的纳米带状结构;溶剂热法制得的VO2（B）经热处理后得到花瓣状纳米团簇的VO2（M）,该花瓣状团簇纳米材料由超薄薄片组装而成,长短不均,宽约数10nm。将VO2（M）纳米粉体、高分子分散剂和硅树脂混合制备得到智能控温包装材料（ICT—PM）;通过变温红外测试,发现以水热法和溶剂热法所制备的VO2（M）为基础的包装材料的相变温度为341K,这一结果为VO2（M）在智能控温包装中的应用奠定了基础。

The pressure of economic growth and the issuance of Urban Investment Bonds: Based on panel data from 2005 to 2011 in China

This paper explores the motivations behind the issuance of Urban Investment Bonds (UIBs) to stimulate local economies in China after the 2008 global financial crisis. Based on panel data from 2005 to 2011, we find that pressure to achieve economic growth has a positive effect on the issuance of UIBs, while fiscal pressure has the opposite effect on UIB issuance. We also find that the tenure of municipal party secretary, the revenue of land-use right transfer and fiscal pressure will change the impact of economic growth pressure on UIB issuance. These results are consistent with a pattern in which China's local government officials are influenced by the central government's assessment of local economic growth performance and have promotion-related incentives to maintain and develop the local economy.     

云南省团队游空间结构及其聚散效应研究

在旅游业高质量快速发展的背景下,全面厘清与掌握省域尺度范围各旅游节点在网络中的角色和地位,并解析其网络结构效应具有重大意义。针对现有研究因旅游流数据采集限制而较少对团队游空间结构研究的不足,基于云南省旅游包车客运信息,运用社会网络结合空间分析的方法,提取了云南省团队游网络空间结构特征,并对其聚散效应进行分析。结果表明:云南省团队游整体网络密度较小且淡旺季表现出相似特征,网络对各节点的旅游联系与合作影响尚未显现,暴露出云南省团队游旅游市场发展的不均衡;团队游网络外向中心势显著高于内向中心势,网络空间集聚趋势明显;通常具有较强外向中心性的旅游节点同时也具有较强内向中心性,表现出“集中—发散”的聚散规律;旅游节点的聚散效应表现为单个节点以圈层状向外递减形式发生,其扩散路径主要集中于文山—蒙自、景洪—思茅方向。整体上,云南省区域旅游业发展差异明显,应重点加强滇西南与滇西旅游区、滇中与滇东北旅游区的旅游资源开发与合作。

Food Package Familiarity and Perceived Amount of Verbal Information: The Moderating Effect of Frugal Behavior

ABSTRACT

This paper discusses the moderating effect of frugal behavior on the relationship between food package familiarity and the perceived amount of verbal information. Two experiments were conducted on food packaging to analyze two central points: (a) the relationship between food package familiarity and the perceived amount of verbal information and (b) the moderating effect of frugal behavior on this relationship. The studies demonstrate the negative influence of food package familiarity on the perceived amount of verbal information. We demonstrate that the greater (smaller) the familiarity with food packaging is, the smaller (greater) the visual attention to the verbal information will be. Second, we show that frugal behavior moderates this behavior. Our experiment shows that a greater (smaller) tendency toward frugal behavior tends to have a positive (maintain negative) effect on the relationship between food package familiarity and the perceived amount of verbal information.     

China's Generation Y's Expectation on Outbound Group Package Tour

This paper aims to identify China's Generation Y's (Gen Y) preference toward joining group package tour (GPT) when traveling abroad and explore their expectations on a number of service attributes. Six service attribute dimensions were identified through factor analysis, including: group leader/local guide(s), optional tour and shopping arrangement, safety, cleanness, and comfortableness, accommodation, activities, and shopping length and frequency. This study confirmed the importance of group leader/local guide(s) with a special emphasis on their honesty. It is found that current group and non-group travelers of Gen Y shared similar expectations on six service feature dimensions, while having different expectations on four service attributes: food hygiene, tour leader's emergency handle ability, Chinese food offering, and park as attraction choice. Results also showed that potential group travelers had higher concern over the factor of group leader/local guide(s) than non-group travelers.     

VONNA(HBP)

ABSTRACT

In this paper, a new learning package, VONNA(HBP), which provides an interactive and online environment for novices to study and practice hotel budget planning, is introduced. Its design philosophy will be discussed thoughtfully with special focus on how to make use of the multimedia and Internet. According to literatures, learning packages are faced to be more effective in delivering teaching material. Researchers indicate that students using a self-paced learning package score higher than in a traditional classroom setting. Moreover, the learning package provides different scenarios for students to explore themselves in a practical environment and is more cost effective and systematic than lectures. Currently, most learning packages in hotel education are not implemented using multimedia with Internet access. Our paper describes a new learning package that fills the gaps.

VONNA(HBP) requires participants to investigate operational budgets on various areas such as sales levels, payroll, inventory level, promotion strategies, and facilities planning, etc. Eventually, the students/novices are required to practice their skills in a comprehensive case about a hypothetical hotel. They need to solve managerial problems by a combination of budgetary planning on human resources, staff training programmes, facilities' maintenance and replacement, or promotion schemes. Analytical tools are available for students/novices to judge an appropriate decision in handling constrained resources.
