旅游的本源涵义探析

汉字具有形义统一的特点,据形索义是解读字、词本义的重要方法,也是探讨旅游本源涵义的一种方法。据形索义,旅和游本义是两种性质不同的活动。旅是“氏”者或“氏”者人群进行的具有明确目标与方向的“失其本居”而到“他居”的活动。游（避）是秉性略“方”但可以称得上“子”的人,以自然山水为审美对象而进行的修身养性活动。“旅游”一词,“旅”为前提条件,“游”为本质核心,因此,“旅游”的本源涵义是基于自然山水审美的修身养性活动。     

矿区不同复垦模式下大型土壤动物功能类群及其分布研究——以山西省平朔矿区为例

研究目的:研究矿区不同土地复垦模式下大型土壤动物的功能类群及其空间分布,揭示大型土壤动物对维持矿区土地复垦后土壤生态系统结构和功能的作用。研究方法:功能类群分析法、群落多样性指数法。研究结果:以平朔矿区为案例区,通过动物分类和群落多样性指数等方法分析了不同复垦模式下的矿区生态系统大型动物类群分布特征。矿区大型土壤动物有2门4纲10目29类,分为腐食性、植食性、捕食性和杂食性4个功能类群,不同功能类群数量占总数的比例自高到低为杂食性(33.74%)植食性(32.10%)捕食性(31.69%)腐食性(2.74%),数量自高到低为植食性(12)捕食性(11)杂食性(4)腐食性(2)。从水平方向分布特征来看,植食性动物在类群数量上为混交林刺槐纯林原地貌小叶杨纯林,杂食性动物在类群数量上原地貌小叶杨刺槐纯林混交林,捕食性动物在各样地中分布比较均匀;从垂直方向分布特征来看,除杂食性外,其他类群都具有明显的表聚性,在各样地中原地貌表聚性最不明显。相似性指数表明生态恢复系统中土壤动物群落相似性整体较低,原地貌与纯林的相似性指数除植食性外其他都高于混交林的复垦模式。研究结论:复垦模式的选择对土壤大型动物群落的形成具有至关重要的意义,研究可为矿区土地复垦后生态系统的恢复与重建提供科学依据和决策参考。     

Home-end and activity-end preferences for access to and egress from train stations in the Copenhagen region

Increasing public transport use with the aim of improving the sustainability of cities should focus not only on enhancing level and quality of the service offered, but also on understanding determinants of the choice of access and egress modes to and from the railway network. This study analyzes the difference in preferences at the home-end and activity-end for travelers who have chosen train as their main travel mode while investigating the effect of policy variables such as car parking availability, bicycle parking availability and type, and bicycle on train possibility. Specifically, this study analyzes the choices between five transport modes (i.e., “walk,” “bicycle,” “car driver,” “car passenger,” “bus”) for 2921 home-end and 3658 activity-end trips. Joint mixed logit models are specified and estimated to account for heteroscedasticity and correlation across alternative modes as well as taste heterogeneity across travelers. Model estimates and pseudo-elasticities uncover the importance of travel time and underline how the improvement of walkability, bikeability, and bus service would contribute significantly to the increase in the probability of choosing sustainable modes to and from train stations. Moreover, model results emphasize the role of bicycle parking in terms of the sheer number of spaces to be increased as well as covered places to be offered at the activity end, de facto giving the possibility to leave a bicycle at that end during the night. Lastly, model results show that it is a matter of not only time and trip characteristics, but also traveler characteristics, occupation, and purpose.     

Selecting the governance mode when offshoring knowledge-intensive activities

The offshoring phenomenon has evolved in recent years, and can be understood from a threefold perspective: first, the evolution in the type of activity being offshored; second, the learning curve involving both the companies implementing offshoring and service providers; and third, the reasons for offshoring. This study proposes an empirical framework that will allow us to explore the interaction between the type of activity (specifically knowledge-intensive) and the drivers of the decision to select the most appropriate governance mode. Specifically, our results show that market-seeking drivers become the primary determinants prompting firms to offshore knowledge-intensive activities through a captive center. In contrast, the motivation to reduce costs moderates the decision to offshore knowledge-intensive activities by nurturing a preference for offshore outsourcing. The empirical evidence is supported by multi-country data from the Offshoring Research Network.

保险公司集团化战略发展模式分析

集团化已经成为我国大型保险公司发展的重要战略选择。而集团化战略的成功,首先取决于企业要拥有优良的品牌声誉和一致明确的企业文化等无形资产、可以共享的客户群及有效的销售渠道等有形资产、以及卓越的战略眼光和组织能力。而在具体实施过程中,必须统筹考虑产业发展策略、资本金补充机制及合理的管理模式,从而通过产业发展的差异化和多元化实现核心竞争力的扩张和价值链内的快速布局和业务增长,提升公司的竞争能力。     

高度城市化区域城中村改造问题——两个案例的比较

在对比分析广州猎德村、深圳上合村两个高度城市化区域城中村改造的具体模式、改造过程中存在的问题基础上,分析不同政策背景下推动城中村改造的途径,得出推进城中村改造的关键问题在于保障村民的发展利益,实现政府、企业、村民三方共赢.对于其中可能存在的矛盾纠纷,政府应更多的以管理者身份引导利益相关者将外部矛盾内部化.     

四川丘陵地区农地流转的问题与对策

农地资源的可持续利用是实现农业可持续发展的基础,农地是“三农”问题的关键环节,农地问题也是我国农村最基本的问题,更是与农村繁荣、农业稳定和农民利益息息相关的重要问题。文章主要阐述了四川丘陵地区农地流转的形式与存在的问题,提出了农地适度流转和推进农地业主开发经营的对策与措施。     

我国农村社会保障问题研究

在城乡二元社会结构下,我国的农村社会保障过分依赖家庭保障和土地保障,已无法适应当前农村经济社会发展的要求,迫切需要建立符合现代文明和体现社会公平与公正的新型农村社会保障体系.为此,应摈弃"经济发展决定论"片面化的思想误区,着重建立健全三项农村基本社会保障制度,拓宽农村社保资金来源渠道,提升土地保障和家庭保障的"造血"功能.
