水生态系统服务供需视角下的水网乡村 适应性规划策略——以吴江张鸭荡片区为例

苏南乡村地区一直是中国乡村建设的先行区域,特殊的纵横交错的水网结构构成了一个错综复杂的系统,呈现出其他地区不具有的复杂性和生态特殊性。随着城镇的扩张,乡村的发展建设使其水网空间的平衡发展面临极大的挑战。传统单一静态的规划方法逐渐显示出无法适应经济、社会等发展要求的缺陷。苏南乡村地区以水为核心,从水生态系统服务供需关系的视角下探究水网乡村的适应性规划策略更加适应当前的乡村现状和需求。以传统水网乡村空间形态转译为基础,建立水生态系统供需服务评估体系,在评估水生态系统服务供需能力的基础上,分析供需分异模式及供需矛盾。从构建乡村水域空间生态格局、乡村水域空间功能分区规划,以及乡村水域空间多情景预判3个方面,提出苏南水网乡村的适应性规划策略,并为水网乡村的生态实践提出新思路。     

基于CNKI的我国旅游专业期刊地域学术影响力分析

采用文献计量学方法,以中国学术期刊评价统计分析系统的网络传播统计数据为依据,统计分析了我国4家主要旅游学术期刊（《旅游学刊》、《旅游科学》、《北京第二外国语学院学报（旅游版）》、《旅游论坛》）的网络传播趋势、读者地域分布、文献海外访问量分区段分布情况。分析结果表明：1）旅游学术期刊的办刊时间长短与网络传播有比较强的联系;2）受CNKI的影响范围和发文文种限制,我国旅游学术期刊地域影响主要集中在亚洲华人集中的地区,3）省市区读者分布情况与我国的区域经济发展水平和旅游教育发展水平有很强的关系;4）我国旅游学术期刊的海外访问情况都不是很理想。综合以上4点．说明我国这4家我国旅游学术期刊的国际化水平还有待提高。     

Assessing greenhouse gas emissions from electric vehicle operation in Australia using temporal vehicle charging and electricity emission characteristics

ABSTRACT

Significant interest exists in the potential for electric vehicles (EVs) to be a source of greenhouse gas (GHG) abatement. In order to establish the extent to which EVs will deliver abatement, however, a realistic understanding of the electricity and transport sector GHG emissions impacts arising from different approaches to integrating EVs into the power system is required. A key issue in this regard is the extent to which GHG emissions are a function of where and when EV charging will be enabled (or disabled) by the provision of recharging infrastructure and implementation of charging management strategies by the electricity industry. This article presents an investigation of the GHG emissions arising from electricity and gasoline consumption by plug-in hybrid EVs under a range of standard EV-power system integration scenarios. An assessment framework is presented, and GHG emissions from EV use are assessed for the New South Wales (NSW) and South Australian (SA) pools of the Australian National Electricity Market (NEM) using retrospective electricity system generation data for 2011. Results highlight that there is a range of possible outcomes depending on the integration scenario and emissions accounting approach used. This range illustrates value of a temporally explicit assessment approach in capturing the temporal alignment of electricity sector emission intensity and EV charging. Results also show the importance of a clean electricity generation mix in order for EVs to provide a GHG abatement benefit beyond what would be achieved by a hybrid (but non-plug-in) vehicle. The extent to which overnight charging in NSW is observed to produce higher emissions relative to unmanaged charging also illustrates a possible trade-off between GHG emissions and benefits for electricity industry from EV charging at times of low demand.     

Factors influencing customer engagement with branded content in the social network sites of integrated resorts

The integrated resorts rely on social network sites (SNSs) for content marketing, while one of the main purposes of content marketing is customer engagement that will leverage the impact of branded content. This study investigates the factors influencing customer engagement with brand posts of integrated resorts on the SNSs. The findings highlight the important influence of both media-type and content-type factors on the level of customer engagement in SNSs of integrated resorts. This study provides practical implications for integrated resorts to develop SNS online content marketing strategy.     

Using a network data envelopment analysis model to assess the efficiency and effectiveness of cultural tourism promotion in Taiwan

The importance of tourism promotion has been discussed throughout past studies, and the consequences of ineffective promotion have also been investigated. While tourism promotion is a topic of interest to many researchers, performance measurement used to assess the effectiveness of tourism promotion is a topic seldom discussed. The purpose of this study is to develop an approach based on the data envelopment analysis (DEA) model to evaluate performance for tourism promotion. The main difference compared with previous DEA models is the evaluation of multiple efficiencies in a single DEA implementation, and the assessment of overall efficiency in a ratio index. In the assumption of variables, we use cultural tourism promotion as a foundation in formulating the empirical evaluation, and we test the proposed model by using data across 20 regions in Taiwan.     

基于动态贝叶斯网络的邻近下穿隧道深基坑施工风险分析

为了减小邻近既有下穿隧道深基坑施工风险及灾害损失,科学预防施工安全事故,提出了一种基于动态贝叶斯网络（DBN）的深基坑施工风险分析模型。首先,运用BWM（best worst method）确定准则的权重;其次,基于关联规则挖掘风险因素间的相互关系,并以此构建DBN结构模型;最后,以新建厦门北站地下一层社会连廊深基坑工程为例,对提出的方法进行有效性和适用性检验。结果表明：基坑围护结构的安全度在静态被评为“较高”和“极高”的概率分别为34.6%和36.1%,且此结果随着输入风险证据发生动态变化,运用反向推理也能迅速找出围护桩渗水风险;提出的模型能明确邻近既有下穿隧道深基坑施工风险传递过程中的关键风险点,并能进行动态风险预测以及事故后致因诊断,从而实现邻近既有下穿隧道深基坑施工风险的动态管控。所提出的优化DBN模型对工前风险评估、先验分析和风险诊断有较好的适用性和较高的准确性,可为邻近既有隧道深基坑施工过程中的安全管控提供有效的决策支持,大幅提高风险控制效率。

基于网络层次分析法的区域软实力评价——以江苏省为例

基于国内外软实力研究文献,考虑各指标间的交互影响、指标的数据获取和量化等因素,构建了包括三级指标的区域软实力评价指标体系,并利用网络层次分析法对江苏省的软实力进行评价。研究结果表明:江苏省的综合软实力排名为全国第二,这主要得益于其区域文化、科技创新能力以及和谐度的排名靠前,而扩散度、人口素质、区域环境以及公共服务的得分偏低。据此提出强化江苏省综合软实力的相应措施:应进一步强化各类传媒的扩散作用、完善公共服务体制以及优化投资以及居住环境等。     

Optimal distribution of the injured in a multi-type transportation network with damage-dependent travel times: Two metaheuristic approaches

We study a location-allocation-routing problem for distribution of the injured in a disaster response scenario, considering a three-type transportation network with separate links. A circle-based approach to estimate the impacts of the disaster is presented. After formulating relations for computing the percentage of the injured, the destruction percentage and the damage-dependent travel times, the problem is formulated as an integer nonlinear program. We utilize a genetic algorithm and a discrete version of the imperialist competitive algorithm for solving large problems. An empirical study focused on earthquakes in Tabriz, Iran, illustrates applicability of the proposed model and performance of the proposed algorithms.
