In addition, when multi-user request ubiquitous services simultaneously, the arbitrariness in resource allocation process easily leads to non-equilibrium of qualities of multiuser's services. Thus, How to design an effective heterogeneous devices cooperation mechanism that meet the QoS requirements and also equilibrate QoS among multi-user's services becomes a very tough problem. In the paper, Equilibrium Index and Theil Utility function are imported to establish a multidevice equilibrium cooperation model, which is benefit for resource allocation in ubiquitous environments. Then a Theil-Equilibrium based Cooperation Mechanism for multi-service is proposed. Firstly, in order to simplify calculating, a dimensionless processing is introduced. After that, a cooperation approach with Theil-Utility Heuristic algorithm is designed to choose the best solution for the simplified model. At last, the mechanism is simulated in a smart home scenario. The simulation results show that this mechanism outperforms non-equilibrium method by improving almost 40% in internal equilibrium with just reducing 0-2% in the total utility ofall the requested ubiquitous services. These data show that the proposed mechanism performs well in equilibrating qualities of multi-user's ubiquitous services.展开更多

It is the inevitable choice for the development of Chinese characteristics for the aged. At present, with the continuous development of the combination of medical care and rehabilitation, the process of combination of medical care and breeding is slow, and the problems of inter departmental cooperation, high cost of resource integration and low service efficiency have emerged. The paper puts forward that multi head management of different responsibility management body is a bottleneck problem that hinders the integration of medical care. From the objective and subjective two points of view, the administrative system level barrier and the inter departmental interest game are the important reasons that obstruct the medical support and break through the estrangement of the Department and realize the cooperation. Then, according to the theory of large part system reform, the author boldly proposes the idea of establishing a new comprehensive functional department that specializes in the management of pension related affairs.展开更多

Since the founding the People's Republic of China, especially for the past twenty years, traditional Chinese medicine undertaking, full of vigor and vitality, has made an unprecedented development in China. The legal status and scientific status of traditional Chinese medicine and pharmacology have already been established. The medical system of traditional Chinese medicine, which is composed of traditional Chinese medicine hospitals, ethnic minority medicine hospitals, integration of traditional and western medicine hospitals and comprehensive hospitals, is playing an important role in preventing, treating diseases and enhancing people's health level. The system of production and circulation for traditional Chinese medicine has basically guaranteed the people's demand for Chinese medicine, with the principles of producing medicinal materials as basis, taking Chinese medicine industry as pillar and Chinese medicine as link. Remarkable achievements have been scored in the research of TCM development as well as research of TCM basic theory and clinical treatment. A number of scientific and technological results have been transformed into productive forces. TCM education has formed a rational pattern based on inheriting traditional way of transmission from master to disciple as well as taking the university and college education as the main part. Minority medical science has been further explored and sorted out; the level of medical treatment, teaching and scientific research for ethnic minority medicines has been improved. As the contingent of integrated traditional and western medicine is growing steadily, medical treatment system, scientific research system and teaching system for integrated traditional and western medicine takes shape progressively. International exchange and cooperation on traditional Chinese medicine has been greatly promoted. Various forms of cooperative relations on the TCM medical treatment, teaching and scientific research have been established between China and many other countries and regions in the world. With the increasing influence of TCM in the world, the accomplishment of traditional Chinese medicine in the 20th century has attracted world attention.展开更多

Albania in the last few years had improved the legal frame so as to give the local authorities the right to initiate PPP projects. The local authorities have not built the expertise for such projects yet. The aim of this paper is to help the local authorities in Albania to support the building of the expertise for such projects. A financial model is used to make the required calculations for the bid at various phases of the project, although this paper is not intended to cover financial modeling in depth, the key inputs and outputs for the financial model are reviewed, including the financing costs. The model has to work within the constraints of: (I) the public authority's requirements for the PPP contract term and service fee profile; and (2) lenders' requirements for the term and payment profile of their debt.展开更多

While they both have gained much from the cooperation, there are also increasing frictions, disputes, complains and dissatisfaction with each other because of the huge trade unbalance problem and other significant issues. The US is eager to expand export to China, but China seems hesitating to decide what to import from the US. This paper presents an analysis about the benefits of the US-China cooperation with a primary focus on the service sector, which remains a large and untapped opportunity for China. The goal of the paper is to explore a new route to relieve the trade balance issues as they separately impact both nations. While focusing on analyzing several immediate opportunities, the paper also investigates several new ideas that rest on technology as well as entrepreneurial development.展开更多

The extension of accountability to the evaluation of educational programs involves significant topics concerning the gap between perceived and real performances. It means that, since many actors such as teachers, students, and external stakeholders are involved in the process, the research on methodologies to distinguish subjective from objective parameters is still on the floor. Debate about performance evaluation in this collaboration is still in progress particularly as it concerns the proposal of several parameters and indexes to quantify the topic and reduce the subjectivism in the assessment and the gap between real and perceived performances. After describing and discussing an evaluation model based on three interdependent typologies of indexes, this will be tested in two Tempus projects having the purpose of activating Ph.D. and masters courses. The results encourage deepening researches in this direction and disseminating this methodology and extending and enriching the validation process.展开更多

Even in homogeneous economic, political and legal systems, the business and state co-operation does not always reach harmony and consensus. Here, the researchers observe more complicated, contradictory and sometimes tense relations between the Soviet state institutions and the Western, particularly American companies, who participated in economic modernization of post-revolutionary Russia, initiated by its leadership. After termination of the New Economic Policy (NEP) (Dziewanowski, 1989, pp. 129-137, 155), and taking foreign concessions back to the state by the beginning of 1930s, the Soviet Union was preparing to become, in a few years, a high-rank industrial power. Giant American steel-making mills, automobile and tractor factories, assembling lines, oil-extracting, and oil-cracking installations, etc. attracted Soviet political leaders, "red directors" and engineers as the best examples to follow up. They were going to accomplish their plans by means of wide technological transfer: ordering and purchasing factory designs, patents and know-how, training Russian workers and technicians both abroad and at the Soviet constructions sites by placing them under supervision of contracted foreign specialists. However, the adoption of machinery and technologies without due organization and chains of supply diminished and distorted expected results.展开更多

In the process of developing supply chain logistics strategy, generally require attention to the following questions: To segment customers, we should determine the appropriate level of customer service, such as order cycle, inventory levels and other modes of transport for different types of clients; Group products according to sales on them, we can take different strategies for each category of products. Order entry, order execution and delivery job processing accounted for a large proportion of logistics activities, which requires technology and management to make the entire processes of supply chain logistics more efficient, especially for the interface area between members of enterprises. We can eliminate redundant work by integrating flow, improve logistics efficiency.展开更多
