The relationship between satisfaction and loyalty: A mediator analysis

This study proposes a multiple mediation model to analyze the relationship between satisfaction and loyalty. The study's contribution to the literature is to examine, empirically, the main antecedents and determinants of this endogenous variable in greater depth. Thus, the research fills a gap in the literature through its analysis of the mediating role of perceived switching costs and the perceived lack of attractiveness of alternative offerings. This study applies variance-based structural equation modeling via partial least squares to a sample of 785 customers from 74 insurance companies in the service sector. The results show that perceived switching costs – to a greater extent – and the perceived lack of attractiveness of alternative offerings – to a lesser extent – are significant mediators in the relationship between satisfaction and loyalty.

不同类型建设用地扩张的时序及空间特征——加速失效模型在静海区的应用

研究目的：分析城市扩展中交通用地、商住用地和工业用地扩张的时序特征、空间关系以及扩张时点的影响因素。研究方法：农地—建设用地转换最优时机理论；加速失效模型。研究结果：（1）不同类型建设用地在扩张过程中具有相互关联的时序和空间特征；（2）静海区交通用地引导了其他建设用地扩张的方向，而不同级别交通用地由于对建设用地和农用地影响的差异，加快或延缓了建设用地扩张的时机；（3）商住和工业用地在200— 400 m 范围内相互集聚，且商住用地产生的集聚效应强于工业用地。研究结论：细化建设用地类型以分析城市扩张的特征和机制，有助于城市扩展区的布局优化和集约发展。     

The Tunisia Wheat Market in the Context of World Price Volatility: A Stochastic Partial Equilibrium Approach

Food security is a key objective of agricultural and food policy in Tunisia. The 2007–2008 food crisis highlighted the negative impacts of price volatility on international markets both in terms of food insecurity and budget exposure. Tunisian food subsidy expenditures ranged from $180 million to $710 million in 2006–2010, so volatile world prices meant volatile subsidy costs. Moreover, cereal production in Tunisia still has much instability due to climate conditions, which also influences imports and, consequently, subsidy expenditures. This study applies a structural model to conduct stochastic analyses of trade and policy impacts on food security and budget expenditures in the Tunisian wheat market. The methodology disaggregates durum wheat and soft wheat markets and generates projections of import prices of durum wheat and soft wheat, using projections of world prices provided by the Food and Agricultural Policy Research Institute at University of Missouri (FAPRI-MU). The key innovation is the generated stochastic analyses of subsidy costs based on stochastic world price projections and stochastic domestic wheat yields based on historic yield variances. The analysis highlights the sensitivity of subsidy costs to world prices, volumes imported and domestic production, so that alternative policy tools can be considered.     

Utilizing the access value of customers

Customers are critical resources for the success of any business, not only because they bring in sales and profits directly, but also because of their access value in a world that is becoming increasingly interconnected. However, the mechanisms by which the customer access value may be exploited and the implication for management has not been well understood. Access value can be defined as the worth of utilizing patrons for further marketing and sales of value-added or third party products. The access value, which mainly results from the aggregation of the customer base and customer data, is essentially a corporation's internalized asset. This article shows that the size of the customer base and the extent of engagement have a significant impact on the customer access value. To develop and gain the benefits of customer access value, traditional business models often need to be transformed: firms and platforms should provide free or subsidized products to attract people and then embed value-added products to make money. The success of the new business model depends on not only the right pricing and product strategies, but also an embedding strategy.

Which commercial partners are important for the most recently admitted EU countries?

This paper describes the degree of trade integration inside the European Union (EU) after the fifth enlargement in 2004. To achieve this goal, we build a database of information on trade flows between the new EU countries (EU‐10) and 180 commercial partners in six different sectors from 1999 to 2011. Using the standard gravity model and estimating a difference‐in‐differences specification, we analyze how joining the EU affected the intensity and direction of the EU‐10's trade flows. Our results show that though trade exchanges between the EU‐10 and EU‐15 intensified after 2004, the impact of integration was much more significant to the EU‐10 group.     

短期影响中国商品房房价因素的计量分析--基于31个省市的横截面数据

房价问题是影响国计民生的重要问题之一，分析房价的影响因素具有重要的现实意义。收集2012年北京、天津等31个省市相关指标的横截面数据，尝试在三种不同情况下用经典线性模型进行逐步回归拟合数据，再对不同模型进行比较，从而选出最优模型。最后，通过最优模型分析得出人均可支配收入与失业率是短期内影响中国商品房房价上涨的主要因素。

黑土典型区有机质高光谱预测模型

土壤有机质(SOM)是鉴别土壤肥力的重要指标,是土壤肥力的物质基础,其含量预测模型研究对于土壤肥力评价、土壤碳库估算、土壤资源利用与保护具有重要意义。该文以黑龙江省黑土带典型区为例,采集区域土壤样本,基于有机质含量与土壤反射率的定量关系,对光谱反射率进行一阶微分和倒对数的处理,建立偏最小二乘法模型(PLSR)、一元线性回归模型和多元线性逐步回归模型。结果表明:(1)土壤有机质敏感波段位于650-750nm。(2)通过比较建模样本与检验样本的决定系数(R2)和均方根误差(RMSE)的大小,得到反射率和倒对数处理后的数据最优模型都为PLSR模型,一阶微分处理后的最优模型为多元线性逐步回归模型。(3)PLSR模型的建模效果优于回归模型,但其预测效果却并不理想。该研究将为改进土壤理化参数、遥感反演、土地质量评价等工作方法提供理论与技术支持。
