This paper investigates the impact of information and communicative technologies (ICT) costs and traditional trade determinants on US trade in education. An extensive panel data from 2000 to 2012 between the US and 49 partnering countries are used. Our findings show that for every 0.01% decrease in communication costs, US trade imports increases by 12.082% between 2000 and 2006; by 13.692% between...

With the explosive development of E-commerce in China, an efficient accurate package distribution is badly needed, causing urban distribution Last Mile Problem. Under the circumstance of worse traffic congestion and environment pollutions in today's cities, not only accuracy and speed, but also alleviation of traffic congestion, air pollutions are highly required while solving Last Mile Problem. Self-pick-up...
With the advent of Massive Open Online Course, or MOOC, academic librarians have already begun to participate in all aspects of MOOC. During the resource construction of a self-built MOOC platform, one issue that the author encounters is to recommend books in the library to disciplines or courses on the platform. Similarity between books and disciplines or courses of all levels is measured according...
In order to reduce the multilayer supply chain logistics cost and optimize logistics integrator task allocation, this paper aiming at the uncertainty of logistics service time, a relatively robust optimization model was established by considering logistics service node soft time window constraints based on the optimal total cost. Genetic algorithm is used to solve the problem, Results show that the...

The paper focuses on the joint emission reduction problem in low-carbon supply chain with Energy Service Company's involvement in the ‘cap-and-trade’ system. Two system dynamics model are included, cooperative R&D investment in emission reduction between the supplier and the manufacturer and Energy Service Company's R&D investment in emission reduction for the supply chain. We discuss the...
We focus on a coordinating issue in the presence of service free-riding in a dual-channel supply chain consisting of a manufacturer and a traditional retailer. We incorporate information asymmetry into the model where the manufacturer has incomplete information about the retailer's cost of providing service, and present an analytical framework and obtain equilibrium decisions in a centralized scenario...
Along with the rapid development of urbanization and motorization, the vehicle ownership in Beijing have created a series of new records in the last five years and the road supply can't keep up with the traffic demand. The road congestion has become one of the main constraints of urban development. In order to alleviate the situation, the Beijing Traffic Management Bureau successively published a...
The existed cloud data models cannot well meet the management requirements of structured data including a great deal of relational data, therefore a two-layer cloud data model is proposed by referencing the relation data model, Hierarchical data model and key value data model. In the representation layer, the concepts of composite class and composite object are proposed to represent nested data structure...
Special articles refer to microorganisms, human tissues, biological products, blood and blood products in need of special management in entry administration. Such articles are related to national biological safety and people's life safety, and have always been the key regulatory objects in entry and exit inspection and quarantine. How to improve the efficiency of the inspection and quarantine supervision...
In order to explain the reason of the high underpricing rate of IPO and to judge whether there exists IPO underpricing, combined with China's specific policy system, this paper classified the IPO first-day underpricing or discount and constructed a classifier by using the decision tree modeling under the multiple influence factors.

With the increasing amount of Automatic Identification System, AIS data, an effective analysis method and technology for large-scale data are a challenge. Information visualization is a suitable technology for people without professional data mining knowledge, such as navigation managers and ship drivers, for understanding mass AIS data. We implement direct and summary visualization of AIS information...
B2C e-commerce enterprises offer many the different kinds but the same variety items are often susceptible to periods of inventory mismatches where best-selling items may face shortages while poor-selling items have excess inventories. Because of capacity constraints, it is a problem that how to sell those poor-selling items quickly and purchase more best-selling items for maximize revenue. In the...
This paper based on the theory of reliability centered maintenance (RCM) techniques aimed to verify the analysis results obtained by GO-Bayes method. This paper addresses the problem of establishing Monte Carlo simulation model to simulate the braking system. Metro vehicle braking system has been selected as it is one of the most complex and high-technology systems among all devices of train vehicles...
