浅析体质投资对旅游院校的重要性

旅游业的日益兴旺大大提升了社会对高质量旅游人才的渴求，然而，目前中国大学生的体育教育不尽如人意，如何加强对学生健康第一教育，体质的投入，在一定程度上决定了培养高质量旅游人才的大问题。     

论流通观念创新

市场经济的实质和核心是交换经济、流通经济;流通不仅是中介,而且直接渗透到再生产的各个领域;流通不是地摊经济,现代流通也要运用高新技术,实现流通现代化;开放是流通的本质特征,市场经济的发达程度与流通的开放程度紧密相连;品牌本身是一种流通现象,品牌形象形成名牌和名牌经济,要在扩大对外开放中让中国自己的名牌走向世界。     

论互联网与保险科技结合的重要性

随着互联网科技的快速发展,其影响力已深入市场经济的各个部分,保险行业依托云计算、大数据等互联网科学技术,不断推动自身发展。但在互联网科技时代,互联网保险行业也出现了诸多问题,有必要对这些问题进行探讨,并提出相应的指导策略。     

企业转让制度之比较研究

企业转让是指为了一定的营业目的通过签定合同将企业作为一个有机组织体的全部财产或部分重要财产进行有偿转让的活动。它是企业的所有权在不同的市场主体之间的移转,既不同于货物买卖也不同于企业财产的转让。企业转让制度在《德国商法典》、《日本商法典》和《韩国商法典》中都有专门规定,但在《澳门商法典》中规定的更为全面,主要涉及商号、债权债务关系、竞业禁止和劳动关系内容。建立企业转让制度是市场经济的内在体现,对我国发展经济和解决就业有着重要的现实意义,同时也符合我国建立现代产权制度的要求。     

Modified efficient importance sampling for partially non‐Gaussian state space models

The construction of an importance density for partially non‐Gaussian state space models is crucial when simulation methods are used for likelihood evaluation, signal extraction, and forecasting. The method of efficient importance sampling is successful in this respect, but we show that it can be implemented in a computationally more efficient manner using standard Kalman filter and smoothing methods. Efficient importance sampling is generally applicable for a wide range of models, but it is typically a custom‐built procedure. For the class of partially non‐Gaussian state space models, we present a general method for efficient importance sampling. Our novel method makes the efficient importance sampling methodology more accessible because it does not require the computation of a (possibly) complicated density kernel that needs to be tracked for each time period. The new method is illustrated for a stochastic volatility model with a Student's t distribution.     

Households transport-home energy conservation strategies in response to energy price policies: A stated adaptation experiment based on portfolio choices and cross effects designs

This article explores consumer investment choice in long-term energy conservation technology and assesses trade-offs in energy saving behaviour between the housing and transportation domains. The long-term energy conservation choice problem is conceptualized as a portfolio choice problem. Consequently, to measure trade-offs between investments in housing and transport options, a cross effects choice design is developed in which respondents were shown one or more alternate ways to reduce their current energy consumption: (1) investing in new technology in the house, such as solar panels; (2) exchanging the current car for a more energy efficient car; (3) buying a new energy-efficient car, such as EV or solar car; (4) moving house to reduce current travel distances. To help respondents linking these options to their current energy consumption, a new Web-based survey system (SINA) to implement and administer stated adaptation experiments was developed. The system was used to collect two sets of data. First, data about out-of-home and in-home energy consumption, together with detailed time use data, was collected. Second, using a cross effects design, respondents were asked to select a portfolio of energy-saving strategies in response to different energy pricing policy scenarios. Results reported in this paper are based on 572 respondents who completed the survey and responded to seven adaptation questions based on their current energy expenditures. A random parameters logit model is estimated to predict the probability of choosing a particular portfolio of energy-saving options. Estimation results indicate that individuals from different socio-demographic groups exhibit varied preferences. The saving option characteristics, especially cost related characteristics have significant effects on individuals' preferences. Moreover, the results also showed significant effects of choice set composition on energy saving options. Further, the energy pricing policies had showed mixed effects on individual's preferences.     

Analysis of congress destinations' competitiveness using importance performance competitor analysis

To be competitive and successful in congress tourism, destinations must learn which congress tourism-related attributes are important and how they perform against their main competitors. This study identifies the importance and performance of destination attributes in Antalya, Turkey, and compares the position of these attributes to those of its main rival in congress tourism, ?stanbul. Importance performance competitor analysis results show that, according to domestic participants, Antalya has to focus on “sight-seeing and cultural attractions” and “outside entertainment.” For international participants, “climate,” “choice of meeting and housing properties,” and “suitability of conference facilities” exhibit higher performance in Antalya than ?stanbul.

基于AHP-DEMATEL的建设用地增长驱动因子重要性研究

近年来城市建设用地增长问题逐渐得到学术界的重视,建设用地增长驱动因子的甄别与影响力分析成为建设用地增长研究的一个重要领域。以传统决策试验与评价实验室方法(DEMATEL)为基础,提出了适合于驱动因子影响力识别的AHP-DEMATEL方法,分析驱动因子对建设用地增长影响的重要程度,获得驱动因子的重要性排序。研究结果发现,经济因素、社会因素和政府因素对建设用地增长的影响明显高于自然因素,政府因素在建设用地增长中扮演着至关重要的角色,GDP、人口和政府发展冲动是影响建设用地增长的关键驱动因子。     

Assessing Systemic Importance With a Fuzzy Logic Inference System

Three metrics are designed to assess Colombian financial institutions' size, connectedness and non-substitutability as the main drivers of systemic importance: (i) centrality as net borrower in the money market network; (ii) centrality as payments originator in the large-value payment system network; and (iii) asset value of core financial services. An aggregated systemic importance index is calculated based on expert knowledge by using a fuzzy logic inference system. We use principal component analysis to calculate a benchmark index for comparison purposes. Overall similarities between both indexes put forward that expert knowledge aggregation is consistent with that based on a purely quantitative standard approach. Specific non-negligible differences concur with the nonlinear features of an approach whose intention is to replicate human reasoning. Both indexes are complementary and provide a comprehensive relative assessment of each financial institution's systemic importance in the Colombian case, in which the choice of metrics pursues the macroprudential perspective of financial stability.
