On October 10, 2011, the Royal Swedish Academy of Sciences awarded the Nobel Prize in Economic Sciences to Professor Christopher A. Sims and Professor Thomas J. Sargent for their work on the interactions between the macroeconomic policies as well as the effects of such policies. This paper presents brief introductions to the two economists, such as their academic experiences, their academic works and research papers, emphasizing the research method and their analytical framework for macroeconomic policies, and the development and application of the models of recurrence and vector autoregression. This article appraises their academic contributions briefly, hoping to find more significant inspirations for the implementation of macroeconomic policies.

Starting with the two major evaluation systems of international competitiveness in the world, combined with the global index of economic prosperity and innovation, this paper analyzes the international competitiveness ranking of World Economic Forum (WEF) and the International Institute for Management Development (IMD) for Brazil, Russia, India and China (BRIC), and their future competitiveness development trends as a whole. It draws a conclusion that the BRIC countries hold comparative advantages. It is found that BRIC countries possess their own strength and enormous potential for cooperation. If an effective mechanism for cooperation is established, turning the comparative potential advantages into international competitive advantages, it can provide an important foundation and prerequisite for the BRIC countries to improve the overall competitiveness.

Classification, analysis and representation of logistics demand, involved in supply chain network design, is the basis of supply chain network design formulation. It could be conducive to the establishment and optimization of supply chain network design model. This paper analyzes the logistics space demand and time demand. With reference to the existing errors and limitations of space demand, this paper proposes the area random demand and node cluster demand based on geographic information processing tools, describing the uncertainty logistics demand by the expected demand function, and formulates the demand uncovering function to represent the time demand. The application direction of demand representation in supply chain network design is given in the conclusion.

Project information collection and risk management method choice directly affect the effectiveness of risk management. On the basis of existing project risk management, this article  presents five channels to collect detailed information on the project from historical statistics, theory, project information and other internal and external sources. Based on several criteria for method choice, it advances a new proposal of constructing method system by combining several methods to achieve more scientific and effective followup risk management. According to postevaluation of risk management, the way to evaluate the methods after project risk management is proposed. Finally, the article, taking the actual risk management in the astronautics project for example, shows the process of information collection and method system establishment as a case of project risk management application.

Psychological ownership is an important predictor for employees attitude and behavior, and it can produce positive and negative effects. According to the data from two clusters of samples, the study is designed to revise the psychological ownership questionnaire (POQ) developed by Avey et al. The result suggests that two types of psychological ownership with four factors are suitable to the POQ in sample 1 consisting of 243 employees, which are promotion focused psychological ownership and the preventionfocused one. The promotionfocused psychological ownership comprises selfefficacy, accountability, belongingnessidentity and the preventionfocused one is examined as a single factor. The results are also validated in sample 2 consisting of 544 employees from another company. The internal reliability for POQ in the two samples is above 0.8, and that for subscales is above 07. The content validity and criterion validity of POQ are acceptable. The promotionfocused psychological ownership is significantly positive with job satisfaction, organizational identification, and affective commitment, while the preventionfocused psychological ownership is not significantly positive.

As a national system, social rescue is related to, but different from, social relief. Social relief is a temporary rescue measure and mostly found in unexpected disasters, such as natural disasters, dangerous diseases and so on, causing heavy loss and threat to a portion of social members life and property. Social rescue, as a responsibility of the government, is a longterm rescue system, aiming to rescue certain social groups. As the governments responsibility to provide longterm rescue to some social groups, social rescue is part of the social security system, ensuring the lowest living standard for those who suffer from disasters and have lost working ability and for the lowincome citizens. The involvement of social work in social rescue is a new task for social management. This article starts from urban community social work practice and analyzes and explores ways for social work to get involved in urban community social rescue.

The origin of purchase of service contracting (POSC) in the West can be traced back to the crisis of the welfare states including governments financial crisis and the subsequent government reform, the wave of marketoriented privatization of public services, and the rise of the idea of new public management. However, in this process of “entrustingbeing entrusted”, there exists a complicated principalagent relationship and multiple accountability issues. While the context in China is different, there is much room for exploring the content, specifications, and the purchasing ways of POSC. It is also imperative to avoid the hasty and overheated development of social work services. The article attempts to illustrate this argument through an example of social service organization in Guangzhou that was established years ago and has participated in the early stage of the government purchase of services.

Solving social disputes with the support of local government and its administrative power not only has a certain legal and social foundation, but also has its unique advantages. The status of courts in our country and the reality of deficient judicial power provide a broad space and necessity for local governments to solve all kinds of social disputes with its administrative power. Against this background, the local government should be regulated effectively in the process of handling social disputes, which would help strengthen our social construction and management and promote the innovation of social management system.
