晋江市土地利用变化对生态系统服务价值的影响

以晋江市为研究区,依据2005年,2010年和2015年3期土地利用数据,从生态系统服务功能角度,运用Costanza的方法,结合谢高地修正的我国生态服务价值当量因子表,分析了晋江市土地利用变化与生态服务价值的响应关系。结果表明:2005-2015年,晋江市的城镇用地显著扩张,而耕地和林地却急剧减少,土地利用的生态系统服务价值总体呈逐年下降趋势。通过分析晋江市土地利用变化对生态服务价值的影响可以为科学合理利用土地,保障人口、资源、环境的可持续发展提供决策支持。敏感性分析表明,生态服务价值对生态服务价值系数的变化是缺乏弹性的,因此结果是可信的。在编制土地利用规划时应将生态服务价值考虑其中,尤其是应注重保护湿地、水域、林地等生态服务价值系数高的土地利用类型,以期实现晋江市的可持续发展。     

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.     

Overconfidence and optimism: The effect of national culture on capital structure

This study assesses whether variations in capital structure across countries can be explained by cultural traits. We analyze capital structure choices of firms in 42 countries and provide evidence that these decisions are affected by the degree of individualism of the country where the firm is located. We assert that managers in countries with high level of individualism exhibit strong optimism and overconfidence which cause an upward bias in perception of supportable debt ratios. Our results are robust to controlling for other firm- and country specific determinants of capital structure choices and to using alternative model specifications and estimation techniques.     

National cultural effects on leverage decisions: Evidence from emerging-market ADRs

We examine leverage decisions in the context of national culture over the 1996–2010 period. Cultural characteristics can explain capital structure decisions from emerging-markets cross-listings. The results show that firms from countries with high Individualism and Indulgence employ more debt. Firms located in countries with high Power Distance, Masculinity, Uncertainty Avoidance, and Long-term Orientation are less leveraged. Additionally, Exchange-traded and capital-raising ADRs are more likely to be from countries with weaker corporate governance. Univariate tests show that capital-raising ADRs employ less debt relative to non-capital-raising ADRs, and notably, in the post-cross-listing period. Interestingly, the home country's cultural characteristics of capital-raising and exchange-traded ADRs exert less influence on their capital structure decisions. Our findings suggest that there is a value discount associated with increased firm leverage. Our insights have practical implications for portfolio managers attempting to enter emerging markets through the use of ADRs. Moreover, investors can evaluate the often neglected effect of cultural values into firm performance.

近年来,城市商业银行保持着快速发展,对外扩张步伐明显加快,异地分行数量迅速增加.在规模迅速扩张的同时,其经营管理风险也在不断积聚.由于城市商业银行经营管理方式较为粗放、盈利手段相对单一、对政府依赖较重,伴随着管理半径的不断增大、同业竞争的日益激烈、宏观调控政策的逐步落实,未来持续经营将面临严峻的挑战.本文试图从城市商业...     

Assessing cross-cultural marketing theory and research: A commentary essay

Cross-cultural research (CCR) is extremely important for advancing understanding of the range and limits of theoretical constructs and frameworks across different cultural contexts. CCR also provides an important understanding of the differences between countries and cultures. This commentary essay examines the review conducted by Engelen and Brettel (2010) and comments on shortcomings, as well as identifying areas where more needs to be done. A critical first step is to properly define the unit of analysis. This step is particularly critical as the concept of “national culture” is becoming increasingly less relevant and the appropriate culture unit for examination is often a smaller, more homogeneous grouping within a given geographic location. This view allows more meaningful inferences to be made and controls for possible contextual confounds, as well as providing a richer understanding of the limits of national culture in an increasingly global economy.     

Cross-cultural entrepreneurship research: Current status and framework for future studies

Although cross-cultural research in the field of entrepreneurship is still in its infancy as a research stream, it offers important inferences for both theory and practice. Some have criticized the relative immaturity of previous survey-based studies’ methodology. In order to address this flaw, we analyze existing survey-based studies in the field of cross-cultural entrepreneurship to identify research gaps in content and methodology and then derive the most appropriate analytical approach to fill the gaps for this type of research. Finally, we present a practical framework in which to conduct sound and prudent future studies, integrating the most appropriate analytical approach, general methodological insights, and the particularities of entrepreneurship research in a cross-cultural setting.

基于相关与偏相关分析的城市居民休闲度假市场开发研究——以南京为例

我国旅游业正向休闲度假型转变。运用相关分析与偏相关分析方法,以南京为例探析城市居民休闲度假旅游需求。研究发现偏爱休闲度假的居民由于地位与收入的不同在旅游资源喜好、旅游活动偏好、购买行为、信息来源渠道、出游方式等方面与一般居民有着明显差异。因此,休闲旅游目标市场的定位应在高学历、中高收入阶层,旅游资源的开发应优先考虑湖泊水滨、森林山地,产品开发应注意项目与资源的耦合且促销渠道应以网络为主,兼顾传统媒介。
