Although personal information privacy concerns have been around for years, the introduction of E-commerce and its associated technologies presents privacy concerns anew. The Fortune 500 represents traditional leadership in the use of technologies and business practices. This preliminary study examines Web sites of the Fortune 500 and shows that slightly more than 50 percent of Fortune 500 Web sites provide privacy policies on their home pages. Comprehensive privacy policies to address all privacy dimensions recommended by the FTC are less common.

Since 1978, the bulk of foreign direct investment (FDI) has gone to the south-eastern coastal areas in China, with only a small portion received inland. With the launch of the Western Development Strategy in 2000 and the Central China Rising Strategy in 2004, the choice of investment locations has expanded to inland areas. Based on panel data covering 98 inland cities from 1999 to 2005, this study identifies location preference variables for FDI invested in China's inland areas, and finds that well-established factors such as natural resources and low labor costs are not important factors in determining FDI locations within China's inland. Instead, policy incentives and industrial agglomeration are the most important factors. The findings of the present study have policy implications for both host country authorities and multinational corporations. Copyright (c) 2008 The Authors.

Agriculture is one of the largest consumers of water and energy. This paper evaluated the agricultural sustainability of the Chenmengquan irrigation district of China based on the water–energy–food nexus. One objective weighting method and one subjective weighting method were integrated, based on game theory, and a matter–element model was constructed to evaluate agricultural sustainability for the research region. The sensitivity of each index to the evaluation class was also analyzed. The results showed that agricultural sustainability was moderate in 2006–2012 and high in 2012–2015. The indexes, which represent water-use efficiency and yield per unit area of crops, had higher sensitivities in the context of the present case study. The results also indicated that agricultural sustainability had a comparatively positive trend between 2012 and 2015, and that pesticide utilization was the most important issue for agricultural sustainability. The approach of using the combination of a weighting method, based upon game theory, and the use of the matter–element model provides a guide for the evaluation of agricultural sustainability.

Mammalian myosin-5b (Myo5b) plays a critical role in the recycling of endosomes to the plasma membrane via the interactions with Rab11a and the Rab11 family interacting protein 2 (FIP2). However, it remains unclear on how Rab11a and FIP2 are coordinated in tethering Myo5b with the vesicles and activating the motor function of Myo5b. In the present study, we show that Rab11a binds to the globular tail domain (GTD) of Myo5b and this binding abolishes the head–GTD interaction of Myo5b, thus activating the motor function of Myo5b. On the other hand, FIP2 directly interacts with both Rab11a and the tail of Myo5b, and the binding of FIP2 to Myo5b does not affect Myo5b motor function. Moreover, Rab11a displays higher affinity to FIP2 than to Myo5b, suggesting that Rab11a binds preferentially to FIP2 than to Myo5b. Based on the current findings, we propose that the association of Myo5b with vesicles is mediated by FIP2, which bridges Myo5b and the membrane-bound Rab11a, whereas the motor function of Myo5b is regulated by Rab11a.
