The motivation of the paper is to find out the influence of demographic characteristic factors on employees’ career promotion in China’s state-owned enterprises and study the relationship between promotion mechanism and enterprise benefits. More than 6,500 pieces of human resource data from China’s state-owned enterprises were studied. Logistic regression is adopted to analyze the correlation between demographic characteristics and promotion. Meanwhile, different data mining methods are used to summarize the characteristics of promotion. On this basis, this study uses the principal-agent model of game theory to analyze the profits of employees and enterprises under different promotion mechanisms and demonstrates the conditions for enterprises to obtain the maximum benefit from the employees’ promotion. The results provide a theoretical reference for the assessment indicator selection of enterprise promotion and help executives better understand the impact of promotion mechanism on enterprises and employees. The application of results can reduce the information asymmetry in promotion incentive, prevent the emergence of adverse selection, and achieve a win-win situation for enterprises and employees.

The telecommunications industry has been undergoing tremendous technological changes, and owning to continuous technological advancement, it has maintained sustained prosperity and development. In this paper, the interplay between technology, market and government in telecommunications is discussed briefly, and then we introduce technology and government into the traditional SCP (Structure — Conduct — Performance) paradigm to develop an industry analysis framework called TG-M(SCP) (Technology — Government — Market (Structure — Conduct — Performance)). Based on this framework, we present the spiral co-evolution model which elaborates on the interaction mechanism of technological innovation with government regulation and market dynamics from the perspective of industry evolution. Our study indicates that the development of the telecommunications industry is the result of the coevolution of technology, government regulation and market forces, and among the three actors, technology is the fundamental driving force. Relative to the "invisible hand" (market) and "visible hand" (government), we conceptualize technology as the "third hand", which fundamentally drives the development of telecommunications industry in coordination with the other two hands. We also provide several policy implications regarding these findings.

Against the background of increasingly mature mobile internet eco-system, internet companies have been continuing pursuing the innovation of internet applications. The action has brought about not only more clicks from the netizens but also gave rise to mounting network burden. Telecom service providers are now faced with the dual pressure from both the soaring broadband building and maintenance costs as well as the declining traditional operating revenues. They wish to find a way to abolish the previous unified pricing model and shift it into the differential charging model by offering graded data flow services. Consequently, the controversy over “net neutrality” has been aroused in the whole society. In this article we analyze the optimum prices in different stages of the internet eco-system, and establish two-sided market model for further research.

Along with the continuous development of wireless communication technology and popularization of multi- mode terminal, the seamless fusion of various heterogeneous wireless networks has gradually become the trend of net- work development. The diversified forms of network access enable the multi-mode terminal to dynamically select the ac- cess network with the highest utility value to obtain network service according to specific standard. The study selects a typical heterogeneous network scenario, abstracts users' network selection process to be group game model, adopts the evolutionary methods, and then studies user's network selection process through replicator dynamics. On the basis of it, it puts forwards a kind of network selection algorithm in the view of replicator dynamics and verifies its algorithm perfor- mance through simulation results, and then analyzes the impact of different factors on evolutionary equilibrium in detail.

This article provides insights into consumer behavior, and the results have important implications for designers, managers, marketers, and system providers of 3G value-added services to explore a conceptual model for analyzing customers’ perceptions of using 3G value-added services. An empirical investigation was carried out to test the hypotheses. The samples include 826 professional participants. Structural equation modeling (SEM) is used to test the relationships of the model. After reviewing the previous research papers, a conceptual model of customer adoption is developed and nine important factors are proposed, namely, perceived usefulness, perceived ease of use, perceived security, perceived price, use experience, perceived enjoyment, need for uniqueness, social influence, context and compatibility. Then a big sample of questionnaire investigation in Chinese 3G value-added service market is conducted. The empirical findings are as follows: (a) security and social influence are two of the most important factors in 3G market; (b) 3G value-added services must be enjoyable and useful; (c) using context should be friendly and compatible. The results not only help to develop a sophisticated understanding of 3G adoption theories for researchers but also offer useful knowledge to those involved in promoting 3G value-added services to potential purchasers.

The paper designs a demand forecast system for online retailers based on big data and the theory of consumer behavior on the purpose of improving regional forecasting accuracy as well as shortening the forecasting periods. The necessity and the urgency of strengthening e-commerce enterprises' forecasting abilities are emphasized from the perspective of enterprises and consumers. Analysis and design process make use of the concepts of Engel-Kollat-Blackwell Model to put forward a framework composed of four phased prediction, which are the Initial Demand, the Possible Demand, the Core Demand and the Effective Demand. The further discussion then details how online retailers could implement this big-data-based system to cope with various shopping scenarios, such as the New Arrival periods and the November 11 Singles' Day shopping spree. By restating theoretical innovation in the field of demand forecasting research, the paper concludes with an outlook of potential improvement of the architecture and the direction of related practices.

Multivariate time series classification is of significance in machine learning area. In this paper, we present a novel time series classification algorithm, which adopts triangle distance function as similarity measure, extracts some meaningful patterns from original data and uses traditional machine learning algorithm to create classifier based on the extracted patterns. During the stage of pattern extraction, Gini function is used to determine the starting position in the original data and the length of each pattern. In order to improve computing efficiency, we also apply sampling method to reduce the searching space of patterns. The common datasets are used to check our algorithm and compare with the naive algorithms. Experimental results are shown to reveal that much improvement can be gained in terms of interpretability, simplicity and accuracy.

Load balancing algorithms and job allocations are main research problems in areas of resource management of future internet. In this paper, we introduce a load balancing model for future internet. We formulate the static load balancing problem in the model proposed above as noncooperative game among users and cooperative game among processors. Based on this model, we derive a load balancing algorithm for computing center. Finally, we execute the algorithm presented in this paper with another three algorithms for comparison purpose. The advantages of our algorithm are better scalability to the model, improving system performance, and low cost on maintaining system information.

In this paper, a kind of modified adaptive group recommender based on overlapping community detection (GROCD) is proposed. Different from existing recommenders, GROCD takes both of group members' preferences and their complex internal interactions into account. In this research, both of overlapping community integration strategy and contribution-based collaborative filtering are employed to explore group members' interests and provide the predicted group ratings on movies. The authors discuss the effectiveness of the proposed approach on Movielens dataset. The results show that the proposed recommender can achieve comparatively accurate prediction with a comparatively low computation complexity.

In SNS, users with different privacy concern levels exhibit different private information posting behavior. To investigate and contrast the effects of personal and interpersonal influence on private information diffusion for different levels of privacy concern of users, we establish a survival analysis model and examine influence factors, including micro-blog features, user features, and social network features. The findings indicate that these three types of factors are very important and have a significant impact on the diffusion time of private information, especially the social network features. The influence factors differ for users with different levels of privacy concern. The results aid in our understanding and prediction of users' performance in SNS, with implications for social marketing and so on.

With the development of network technology and the increasing popularity of the network, the Internet Word-of-Mouth is gradually replacing its traditional counterpart. People increasingly prefer to collect product information using the network exchange in order to make consumption decisions. Involvement theory plays an important role in the theory of consumer behavior; it explains why people sometimes did not follow the rational model-information collection, screening, and assessment to do purchase decision. Researching the role of involvement to IWOM is significant to the development of marketing theory and effective marketing communications. This paper regards college students as survey subjects, focuses on the impact of variables of involvement to IWOM, and conducts the demonstration to get conclusions so as to recommend appropriate management recommendations to help the corporation better carry out the publicity and marketing of product.

Synchronization is a crucial task and big challenge for ultra-wideband (UWB) systems, especially in the presence of inter-symbol interference(ISI) and inter-frame interference (IFI). This paper proposes a blind synchronization and demodulation algorithm that is capable of mitigating ISI and IFI for noncoherent UWB system. Employing a series of codeword matching and averaging operations, the proposal can suppress interference and noise effectively. Moreover, it can acquire synchronization rapidly and improve the bit error rate (BER) performance significantly thanks to efficiently exploiting the observed signals. Simulation results demonstrate the substantial performance improvement compared to existing methods.

Traditional collaborative filtering algorithm is a weighted average prediction algorithm based on nearest neighbors' ratings. Besides similarity between users, trust and credit are also parameters to affect recommendation. This paper proposes a computational model of credit factor and then a collaborative filtering algorithm based on it. This model is based on trust factor and takes credit model as the basic elements. This proposed algorithm further improves the validity and accuracy of the recommendation.

RFID (Radio Frequency Identification) technology has a huge market potential in China. Spectrum management of RFID will therefore play an important role. The specificities of frequency resource decide that the government must be responsible for spectrum management and ensure a sound market order. However, excessive control of government could hinder the development of RFID industry, which needs to be promoted by all participants. This paper considers the experiences of the United States and Japan. It proposes that the practice of RFID spectrum management in China should be guided by the government, led by enterprises, planned scientifically, unified in standards, and encourage innovations. During this period of financial crisis, the government should expand domestic demand, accelerate the restructuring and upgrading of China's industry, and promote the fast development of RFID industry.

On the transformation of China's telecommunication operators, this paper builds a structure of the industry's ecosystem and value-net model, and further identifies key resources in this ecosystem, including standardization, core technology, customer base and brand names. The conclusion is that an operator's competitive advantage not only depends on its own strength, but also on its capability of collaboration. That is, whichever operator can best collaborate with others in the ecosystem, will also be able to best integrate resources, and thus establish a self-centered ecosystem and obtain a sustainable advantage.

The networks literature suggests a network's value increases in the number of locations it serves (the ldquonetwork effectrdquo) and the number of its users (the ldquoproduction scale effectrdquo). In this article we discuss one of the technology innovation in optical industry- photonic integrated circuit (PIC) technology. We show that, in one hand, consumers (traditional carriers) would be very careful to adopt a new technology or product in presence of network effect, which results in new technology adoption delays increasing in the size of traditional networks. In the other hand, if benefit from this new technology is not certain, dominant suppliers (equipment vendors) prefer waiting and collecting information to make further decision, so in some time network effect reduce innovation incentives.

3G has already been put into business, but the killer application of M-commerce has not been found out. The root cause is because the value transfer system of M-commerce has not been thoroughly researched or analyzed. Through a series of empirical study, this paper points out that the value loop in E-commerce is right the key problem of killer application in mobile value-added service. Accordingly we established a related model and gave the critical factors and methods for creating the M-commerce value loop; they are referable for the development of M-commerce.

Now, the telecom service providers are faced with significant challenges as the traditional separated network and service become converged. Customers move to care more about the quality of service, such as the provision time, fault disposal, bill management, and security issues, other than networks. The carriers must integrate their core legacy mainframe operation support systems (OSS) with new generation components that can handle the requirements posed by new service offerings, which means the NG-OSS should pay attention to customers rather than networks. This paper examines the legacy OSS frame with its main component and analysis which part should be weakened or converged, and which part should be enhanced or updated. Then it suggests a more idealized view of a functional OSS architecture that conforms to the concepts of the TeleManagement Forum’s Telecom Operations Map (TOM) model. In the last, it discusses how to evolve the OSS from the network-focused to customers-focused successfully and smoothly.

The rapid development of mobile commerce (m-commerce) has profound influence on logistics industry. Firstly, through analysis that combines m-commerce and the logistics industry, the paper draws a conclusion that main m-commerce applications in logistics industry include cargo tracking, mobile inventory management, vehicle positioning and M2M (machine to machine) mobile services. Then, we think traditional logistics has entered the stage of electronic commerce logistics and is turning into the stage of m-commerce logistics gradually after analyzing relation between m-commerce and logistics. As m-commerce logistics differs from traditional logistics, there is unique operation process of m-commerce in logistics industry. Finally, from the perspective of value chain, the paper points out that there are three mobile commerce models including B2E (business to employee), B2B (business to business) and B2C (business to customer).

Mobile commerce (MC) refers to e-commerce activities carried out using a mobile device such as a phone or PDA. With new technology, MC will be rapidly growing in the near future. At the present time, what factors making consumer accept MC and what MC applications are acceptable by consumers are two of hot issues both for MC providers and f or MC researchers. This study presents a proposed MC acceptance model that integrates perceived playfulness, perceived risk and cost into the TAM to study which factors affect consumer MC acceptance. The proposed model includes five variables, namely perceived risk, cost, perceived usefulness, perceived playfulness, perceived ease of use, perceived playfulness. Then, using analytic hierarchy process (AHP) to calculate weight of criteria involved in proposed model. Finally, the study utilizes fuzzy comprehensive evaluation method to evaluate MC applications accepted possibility, and then a MC application is empirically tested using data collected from a survey of MC consumers.
