非工作时间工作连通行为对工作拖延行为的影响机制

基于趋避模型,以自我效能感和工作疏离感为中介变量,趋近倾向和回避倾向为调节变量,构建非工作时间工作连通行为对员工工作拖延行为的理论模型。对281份员工问卷数据进行处理、分析。结果表明,非工作时间工作连通行为与趋近倾向正向交互影响自我效能感,并通过自我效能感减少工作拖延行为的产生;非工作时间工作连通行为与回避倾向正向交互影响工作疏离感,并通过工作疏离感促使工作拖延行为的产生。     

基于变化分析的基本农田划定成果评价方法初探——以东港市马家店镇为例

东港市马家店镇新一轮土地利用总体规划修编划定的基本农田在地类构成质量上略有降低但基本保持平稳,农用地平均质量等级高于划定前平均质量等级,集中连片性有所提高,基本农田划定成果基本符合《基本农田划定技术规程》原则要求,具有科学合理性.基于地类构成、农用地平均质量等级、集中连片性变化分析的基本农田划定评价方法具有一定的合理可行性,为建立完善合理的基本农田划定成果检查验收方法提供了初步探索经验.     

Connectivity levels and the competitive position of Spanish airports and Iberia’s network rationalization strategy, 2001-2007

This paper examines the connectivity of the Spanish airport system between 2001 and 2007. Over the period, network carriers considerably strengthened the connectivity between Spanish airports and major European hubs. Although OneWorld is still the dominant alliance in Spain, SkyTeam and Star achieved a larger connectivity share through the growth of indirect services provided through their northern European hubs. In addition, the network rationalization strategy of Iberia and its decision to concentrate operations at Madrid-Barajas had important implications for the connectivity of other Spanish airports. Low-cost carriers have boosted direct connectivity from secondary Spanish airports.     

Does the Connectivity of the Belt and Road Initiative Contribute to the Economic Growth of the Belt and Road Countries?

ABSTRACT

Since the Belt and Road Initiative (BRI) has been implemented for five years, it is time to ask whether the BRI contributes to Belt and Road (BR) countries’ economic growth, and how are the five elements of connectivity implemented between China and its partner countries since the BRI was proposed. This study focuses on the development of the five elements of connectivity between China and the BR countries from 2008 to 2017 using a comprehensive connectivity index extracted from principle component analysis, and then investigating if the connectivity has contributed to the economic growth of the BR countries with quantitative analysis of the fixed effect econometrical model. It is found that Russia, South Korea, and Singapore presented the top three levels of connectivity with China with regard to the overall connectivity index, varying from 1.4 to 2.4. Madagascar and Panama have the lowest level of connectivity with China, with values of ?0.8 to ?1.1. The result of the fixed effect model shows that the connectivity of the BR countries with China contributes to their economic growth. This provides quantitative evidence that the connectivity between BR countries and China has a significant influence on the economic growth of those countries.
