The competitive balance of professional sports league is studied by bibliography and specialists visiting. The causation, rationality and probability of professional sports league's pursuit of competitive balance are analyzed and the level of competitive balance is evaluated by adopting the case of National Basketball Association. The institution and practice of regulations of revenue sharing, salary...
Organizational citizenship behavior is a hot topic in the area of modern human resources management, which focuses on the initiative behaviors beyond the requirements of position duties. OCB can influence organizational performance by increasing the ability of employees, motivating intrinsically, extending resources and creating favorable environments. There are mainly four factors affecting the organizational...
The paper establishes the evaluation index system of resource allocation in S&T. The method of DEA is adopted here to evaluate not only the technical efficiency of fiscal input in S&T in different regions and economic growth but the co-efficiency of the technique and the scale on the basis of the data in 2006 of the fiscal input in S&T in 31 regions and the economic growth.
The paper discussed the regional development law of land reform to follow, form the current land management system. It analyzed the definite of land reform to strengthen the understanding of the current land system, and specific to explore the reform and improvement of the existing system of the land based on the characteristics of the market economy, and it has certain practical significance.
This article focuses on the performance measurement of non-for-profit organizations. Most of the existing researches just copy the method for the for-profit organizations performance measurement and apply to the non-for-profit organizations. In this article, I find out that there no core performance measures in the non-for-profit organizations which make the core-measurement, the method of for-profit...
Human resources management plays very important roles in the development and operations of enterprises. And motivation mechanism can affect the exertion of maximum effect of human resources management. That's to say good and timely motivation can tap employees' potentials and arouse employees' initiatives. It's favorable to the development of enterprises, and vice versa. Therefore it's quite necessary...
In this paper, reasonable cost-sharing steps and the corresponding counting model of various types of transmission services were elaborated.On this basis, the transmission price formation mechanism was discussed. In deciding the principles of transmission cost allocation, the thinking of large scale system theory with voltage level decomposition was applied so that cost allocation model reflects the...
Abstract- To reduce the construction complexity of multi-agent system, the proposal is presented that combining several small systems into a larger one, and obtain the properties of the larger system through the properties of small systems. Make reference to dynamic task allocation based on contact protocol, the macroscopical model for task allocation and the microscopical model for agent inner BDI...
One of the well studied issues in multiagent systems is the action-selection and sequencing problem where a goal is decomposed in tasks that can be performed in different ways and/or by different agents. This problem has been tackled under different approaches. In particular, for open, dynamic environments agents must be able to adapt to the changing organizational goals, available resources, their...
This paper addresses the optimization of resource allocation based on Decode and Forward (DF) or Amplify and Forward (AF) relaying techniques for packet access Orthogonal Frequency Division Multiple Access (OFDMA) networks. A power allocation quasi-optimal solution with a low complexity has been proposed for the two forwarding techniques. To illustrate theirs performances, a selection of numerical...
We give the first black-box reduction from arbitrary approximation algorithms to truthful approximation mechanisms for a non-trivial class of multi-parameter problems. Specifically, we prove that every packing problem that admits an FPTAS also admits a truthful-in-expectation randomized mechanism that is an FPTAS. Our reduction makes novel use of smoothed analysis, by employing small perturbations...
Various attribute and relation information is used in social recommendation systems. However, previous approaches fail to use them in a unified way. In this paper, we propose a unified framework for social recommendation. Entities like users and items are described by their tags. We model each entity using topic models like Latent Dirichlet Allocation(LDA) and then connect these topic models to form...
We study a novel class of mechanism design problems in which the outcomes are constrained by the payments. This basic class of mechanism design problems captures many common economic situations, and yet it has not been studied, to our knowledge, in the past. We focus on the case of procurement auctions in which sellers have private costs, and the auctioneer aims to maximize a utility function on subsets...
In a downlink orthogonal frequency division multiple access (OFDMA) system, allocating sub-channels and power across multi-user can require excessive feedback of channel state information. An efficient proportional fair scheduling algorithm based on cluster feedback scheme is proposed in the paper. Simulation results show that the scheme needs only little feedback information while maintaining guaranteed...
The web is a crucial source of information nowadays. At the same time, web applications become more and more complex. Therefore, a spontaneous increase in the number of visitors, e.g., based on news reports or events, easily brings a web server in an overload situation. In contrast to the classical model of distributed denial of service (DDoS) attacks, such a so-called flash effect situation is not...
Scientific task allocation and knowledge workers scheduling is an important part of rational human resources management in enterprises. In this paper, ant colony algorithm is used to research task allocation and knowledge workers scheduling. Ant colony optimization algorithm can reduce the number of optimization iteration and computing time. Elite solution retention tactics is used in iterating process...
In this paper, we present a pilot design for an OFDM cellular system based on Costas arrays. The design provides pilot symbols for both common and dedicated pilots for MIMO transmission. The pilot symbols are designed so that pilots from different cells intersect minimally. The design results in a large number of available distinct pilot symbol patterns with minimally overlapping resource elements...
Interference mitigation and adaptive multi-user resource allocation are among the most promising technological breakthroughs that should improve capacity of future broadband wireless communications. In a multi-cell scenario, where co-channel interference is the performance limiting factor, discrete-rate resource allocation algorithms, selecting those channels with best Signal-to-Interference and Noise-Ratio...
This study addresses the general problem of efficient resource management in wireless networks with arbitrary time-varying topologies. Communication channels are assumed to generally accommodate multiple simultaneous transmissions. In this context, we focus our attention on the problem of distributed transmission power allocation and medium access by links (transmitter-receiver pairs) that require...
Inter-cell interference is a major problem in multi-cell OFDMA systems and can severely degrade the system throughput, particularly for cell-edge users. An efficient technique to mitigate inter-cell interference (ICI), is interference coordination that allocates certain resources among users in different cells. In this paper, we propose a novel and distributed algorithm in order to mitigate the inter-cell...
