为了掌控供电企业现存的人力资源风险状况,及时规避人力资源风险。本文建立了符合供电企业人力资源特点的人力资源风险评价指标体系。通过层次分析法和线性加权法确定人力资源得分。在对人力资源风险等级划分中,引入云模型。该模型摒弃了以往研究的硬划分,更能体现数据的分布特性。然后对评价对象进行逆向正态云化来获得其云参数,最后利用该云参数进行评价。通过实例证明,该模型能够挖掘出更多隐含的信息,具有可行性和有效性。  相似文献

The purpose of this study threefold: to determine whether a shared cultural model of the importance of a set of leisure activities to a good leisure life existed in urban Taiwan, the degree to which cultural consonance in leisure mediates the relationship between leisure constraints and leisure satisfaction, and the degree to which leisure satisfaction affects life satisfaction and self-rated health. Results indicate that a cultural model of the importance of leisure activities to a good leisure life existed among sample members. Second, higher levels of self-reported participation in leisure activities that are culturally agreed upon as more important for a good leisure life are more strongly associated with leisure satisfaction than are activities culturally agreed upon as less important. Finally, leisure satisfaction strongly predicts both life satisfaction and self-rated health.  相似文献

Using spatial panel data comprising a cross section of 1,461 continuously active Airbnb listings obtained from AirDNA, as well as time series data from NYC and Company and the OECD covering the time period September 2014 to June 2016, the present study quantifies own price, cross price, and income elasticities of Airbnb demand to New York City within an empirical tourism demand framework. The particular goal of the study is to establish whether the relationship between Airbnb and the traditional accommodation industry is of a substitutional or of a complementary nature. Employing a one-way fixed-effects spatial Durbin model, it can be concluded that demand is price-inelastic for Airbnb accommodation in New York City, which is a luxury good, and that the city's traditional accommodation industry as well as neighboring Airbnb listings are substitutes for the investigated Airbnb listings. The estimation results are robust against several alternative specifications of the regression equation.  相似文献

ABSTRACT

This study aims to explore the typology of hotel crime and how it is related to guests’ fear of crime based on a cause-and-consequence model. A total of 873 TripAdvisor reviews were content-analyzed to develop a typology of hotel crime. High-class hotels experienced more theft, fraud, and burglary while low-class hotels encountered more prostitution and drug-related activities. Hotel guests generated a higher fear of crime when crime occurred inside guest rooms, especially in cases of burglary, theft, or fraud. Reviews mentioning crimes were perceived to be more helpful. Managerial implications and best practices of crime prevention are provided for hotel practitioners.  相似文献

Despite empowerment being a crucial component of sustainable tourism, few scholars have quantitatively operationalized empowerment and looked at how it applies to rural societies within the post-communist European Union (EU) member states. Knowing the high priority of sustainable rural development goals within the EU, empowering residents within these post-communist societies has become a pertinent issue especially where those societies appear more reluctant to engaging in democratic ways of decision-making. In response to this gap, this study tests the cross-cultural validity of the Resident Empowerment through Tourism Scale, and then evaluates how empowerment predicts residents’ support for tourism within the municipality of Choczewo, Pomerania, Poland. Using a theoretical perspective that blends Social Exchange Theory with Weber's Theory of Formal and Substantive Rationality, these non-economic empowerment dimensions are coupled with a measure of resident perceptions of economically benefiting from tourism to see if rural residents in Choczewo, Poland, are more swayed by the economic or non-economic benefits of tourism. Results show that residents within this Central and Eastern Europe setting are more influenced by the pride and self-esteem boost associated with psychological empowerment and the perceptions of increased community cohesion (i.e. social empowerment) than the economic promises of tourism.  相似文献

线性文化遗产是一种特殊的遗产类型,随着人们对遗产完整性不断深入的理解以及遗产活化利用理念的发展,线性文化遗产旅游的重要性日益显现。因此,树立线性文化遗产意识,把握线性文化遗产特征,是推进线性文化遗产旅游利用和可持续发展的重要问题。本文以《世界遗产名录》中收录的线性文化遗产为基础数据,对线性文化遗产的类别与列入标准、资源组合模式和核心区与缓冲区等典型特征进行深入分析,并从旅游空间演化和旅游活化路径两方面总结其对旅游利用模式的影响,以期为线性文化遗产旅游的可持续发展提供科学参考。研究结果表明,线性文化遗产旅游空间结构发展过程遵循“增长极”演化规律,并在遗产文化分层上表现出不同的利用方式和活化路径。  相似文献

The aim of this study was to find the optimal position limit for the Chinese stock index (CSI) 300 futures market. A low position limit helps to prevent price manipulations in the spot market, and thus keeps the magnitude of instantaneous price changes within the tolerance range of policymakers. However, setting a position limit that is too low may also have negative effects on market quality. We propose an artificial limit order market with heterogeneous interacting agents to examine the impact of different levels of position limits on market quality, measured as liquidity, return volatility, efficiency of information dissemination, and trading welfare. The simulation model is based on realistic trading mechanisms, investor structure, and order submission behavior observed in the CSI 300 futures market.Our results show that on the basis of the liquidity status in September 2010, raising the position limit from 100 to 300 could significantly improve market quality and at the same time keep the maximum absolute price change per 5 s below the 2% tolerance level. However, the improvement becomes only marginal if the position limit is further increased beyond 300. Therefore, we believe that raising the position limit to a moderate level can enhance the functionality of the CSI 300 futures market, which should benefit the development of the Chinese financial system.  相似文献
