Utilizing urban form characteristics in urban logistics analysis: a case study in Lisbon,Portugal

Within the realm of urban logistics, Macário (2013) developed a hypothesis, denominated the Logistics Profile (LP) concept that suggests homogeneous groups of urban zones with respect to three dimensions, which could be used to analyze freight movement policy: (1) the social and built environment; (2) characteristics of the goods/products being moved; (3) characteristics of the deliveries at the receiver establishment. The concept was expected to ease the transferability of best practices in city logistics, by analyzing similarities and differences between zones. This research uses a quantitative methodology to apply the LP concept, and assess its potential, using the city of Lisbon as a case study. The analysis is focused on: (a) the extrapolation of freight trip generation per establishment and delivery characteristics from a sample of commercial establishments to the population within the case study, (b) proposing a methodology to test the LPs, (c) testing the existence of proposed LPs. Freight trips have been extrapolated using a Multiple Classification Analysis (MCA) model. Freight delivery characteristics were attributed to establishments from a sample-based probability distribution. LPs were tested using a two-step cluster analysis. Some LPs have been matched with clusters of case-study zones, subject to case study particularities. Profile overlap was not an issue and occurrences were expected. The testing showed that Logistic Profiles have the potential for being used as a departure point for urban freight planning and policy analysis.     

Voluntary carbon offsetting: Who does it?

Voluntary carbon offsetting was popularised during the last decade, particularly by airlines, as a tool to ‘neutralise’ emissions associated with travel. Although there is a wide range of carbon offsetting schemes for tourism, the uptake of these programs has been reportedly low. Regardless, little research has explored the visitor segments who voluntarily undertake carbon offsetting. Consequently, this research investigates the prevalence of carbon offsetting amongst international tourists to Australia between 2008 and 2010 and, using cluster analysis, segments the carbon offsetters into three distinct markets. Findings reveal a stable carbon offsetting market, despite a Global Financial Crisis occurring during the reference period. Further, travellers from the United Kingdom/Europe were more likely to carbon offset, while those from Asia were less likely to participate in the schemes. Thus, this could indicate that the social marketing, public discourse and substantial media coverage in the United Kingdom/Europe had enhanced climate change mitigation behaviours.     

A study on the importance of airline selection attributes by airline type: An emphasis on the difference of opinion in between Korean and overseas aviation experts

The main purpose of this research is to understand the relative importance of airline selection attributes that are considered important by passengers when selecting an airline. Specifically, we analyzed how the attribute selections differed based on airline types, a Full Service Carrier (FSC) and a Low Cost Carrier (LCC). For this purpose, a Delphi analysis was performed with 34 Korean aviation experts and 32 overseas aviation experts as the target sample groups. Statistical tests including Mann-Whitney U Test and Wilcoxon Signed Rank Test, were used to analyze the selection attributes. In the case of FSCs, safety, flight schedule, cabin interior, and fast check-in processes were considered to be important selection attributes whereas for LCCs, air fare level, flight safety, the convenience of air ticket purchasing procedures, and additional charges were considered to be the important selection attributes. Additionally, there was a difference in the importance of airline selection attributes depending on whether it was a Korean or overseas aviation market. The result of these findings may be utilized as basic data in establishing a marketing strategy for an airline company to attract more passengers.     

环境与就业维度下出口商品结构优化——以江苏为例

利用计量方法从环境和就业这两个指标来考察江苏出口商品结构优化,其中环境指标主要是通过碳排放指标来体现的。通过研究发现江苏九大类出口商品在环境和就业指标上都无此消彼长现象,其中对两指标都具显著影响力的为机械及运输设备,化学品及有关产品和按原料分类的制成品这两类出口商品仅对环境有着显著影响力,对就业不具显著影响力,至于其他种类的出口商品则对环境和就业这两个指标都不具显著影响力,最后得出江苏出口商品结构优化的最明确方向,即大力促进机械及运输设备的出口,抑制化学品及有关产品和按原料分类的制成品这两类出口商品的出口。     

基于耦合协调度模型的南京市用水效率与经济发展关系

基于2007—2014年南京市用水效率与经济发展的时间序列数据,构建南京市用水效率系统与经济发展系统间的耦合协调度模型,探讨南京市在2007—2014年期间用水效率与经济发展之间的动态均衡关系。首先对用水效率系统和经济发展系统的综合状况进行评价,然后对两系统的耦合协调度进行定量分析。结果表明:2007—2014年南京市用水效率和经济发展水平都有大幅度增长;两者的耦合协调关系在波动中逐渐优化,2007年处于低度协调耦合阶段,2008年处于中度协调耦合阶段,2009—2014年处于高度耦合协调阶段;只有提高用水效率与经济发展并举,才能保持耦合协调度的增长趋势。最后针对用水效率系统和经济发展系统存在的不足,提出在用水效率方面优化用水结构、加强水质污染治理,经济发展方面则调整经济结构、增强经济活力等建议。     

A Segmentation of Volunteers at the 2013 Austin City Limits Music Festival: Insights and Future Directions

Volunteers at music festivals play a critical role in festival operation and success. As the music festival industry continues to grow, the ability for these large productions to effectively execute a large volunteer program is augmented. Volunteers from the 2013 Austin City Limits Music Festival were surveyed in regards to their self-image congruency, motivation, satisfaction, and intent to return as a volunteer at the festival. Analysis resulted in three distinct segments which has significant practical implications for festival management. Academic implications exist with the addition of self-image congruency and further discovery of volunteers in the festival and event industry.     

Effects of land urbanization and land finance on carbon emissions: A panel data analysis for Chinese provinces

The rapid urbanization in China comes with several economic, social, and environmental issues, most of which are related to land use. This study contributes to research on the land–growth–environment nexus by investigating the effect of land urbanization and land finance on carbon emissions in China from 2004 to 2013 using the Stochastic Impacts by Regression on Population, Affluence, and Technology (STIRPAT) model. Results show that land finance and land urbanization significantly affect carbon emissions. The rate of land urbanization contributes to the reduction of carbon emissions; however, it has less impact compared with other determinants. The effect of land finance and land urbanization on carbon emissions indicates that a local government’s willingness to lease land for revenue aggravates carbon emissions. Economic growth and industrial structure also influence carbon emissions. Furthermore, the land requisition system and rural land conversion market should be enhanced through the guidance provided by the 13th Five-Year Plan (2016–2020) to promote the diversification of land transfer, fully consider regional differences, and establish a distinct policy focus that can contribute to emission reduction and land use.     

Renewable energy and low-carbon policy spillover effects on natural gas demand

Recent legislation intended to increase the use of renewable energy sources and lower the amount of carbon dioxide emissions from energy has changed the structure of energy markets. The effect of these policies on carbon-intensive fuel sources is rather obvious. For natural gas, though, the effect is not immediately clear. This letter uses a structural model of natural gas demand to uncover whether these policies have led to increased demand because natural gas is a relatively clean source of energy that couples well with renewables or if these policies have crowded out natural gas on net.     

Exchange rate effect on carbon credit price via energy markets

This paper examines the impact of currency exchange rates on the carbon market. We scrutinize this effect through the European Union Emission Trading Scheme (EU-ETS), which primarily uses two substitutable fossil energy inputs for the generation of electricity: coal and natural gas. The European coal market is directly driven by global coal markets that are denominated in USD, whereas, natural gas is mainly imported from Russia and is denominated in Euros. The impulse response functions of a Structural Vector Autoregression (SVAR) model demonstrate that a shock in the Euro/USD exchange rate can be transmitted through the channel of energy substitution between coal and natural gas, and influence on the carbon credit market.
