Based on a survey o foyer 5,000 enterprises conducted by the People＇s Bank of China, we have attempted to compile a finished goods inventory index of the 5,000 enterprises. Through our analysis, we are able to determine that the 5,000 enterprises inventory index displays the basic features of pro-cyclicality and fits the business cycle with a lag of one quarter. Currently, the inventory index shows signs of declining after five consecutive months of increases, indicating that the expansion of enterprises＇production is temporarily slowing down.展开更多

This paper analyzes the franchise value change information of state-owned commercial bank. The franchise value change information shows that the franchise value of state-owned Commercial Bank is descending. Along with the descending of the franchise value, state-owned commercial bank strengthens its high risk investment motive when it chooses its investment strategy. State-owned commercial bank tends to run the high risk of investing securities because its investment variety is very sparse. Based on the theoretical principle of how to control securities investment risk, this paper proposes some countermeasures and suggestions that state-owned commercial bank strengthen the control of its securities investment risk in order to perfect its investment strategy.展开更多

High grain prices,which still have a possibility to go up further,have attracted wide attention across the world,including in China.As early as the end of last year,the State Council issued a circular that mandated the stabilization of grain prices in order to strictly crack down on illegal actions such as dishonest merchants driving up grain prices.One time,five State-level Departments led by National Development and Reform Commission,released an urgent announcement in order to safeguard the stability of grain prices in the domestic market.Wu Xiaoling,Vice Governor of the People's Bank of China,said that the negative influences exerted on other product prices by the rise in global grain price should not be ignored.According to Wu,the People's Bank of China will continue to closely watch the price changes. From a global and comprehensive viewpoint,the article analyzes the features of the recent grain price hike and the reasons for its dramatic rise,as well as,the impact it will have on the global economy.展开更多

The main source of data used for analysis and inference was information originating from the authors＇ own investigations conducted in 2013 on a group of 500 rural households and on a group of 150 trade and service points operating in non-urbanized areas. This work made use of statistical summary measures and Z2 independence test. According to the results of the conducted studies, forms of payment used by rural dwellers depend on many variables, of demographic, economic, and psychological character. Cash payments are more frequently used by persons possessing vocational or secondary education, elderly people, old-age pensioners, annuitants, or households with lower incomes. Also, persons who do not trust financial institutions or do not perceive benefits resulting from the use of non-cash instruments prefer cash. It is a group of households which require urgent educational activities in the area of non-cash payment instruments. A significant barrier to using non-cash payment instruments by rural dwellers was a limited access to non-cash channels. It is connected in the first place with a poorer development of financial infrastructure in rural areas （banks or cash points）, insufficient Internet access conditioning a possibility to use electronic banking points, and also a worse development of credit card acceptance network. As has been demonstrated by the results of conducted studies, the main reason for a lack of point of sale （POS） terminals in retail and service-providing points operating in rural areas, in the opinion of their owners, is the very high interchange fee （50% indications）, which under Polish conditions is one of the highest in the European Union （EU）.展开更多

Used for this purpose today, the most effective strategy comes at the beginning of micro-credit system. Microcredit, in particular in the area of the individuals, and its opportunities to increase the credit to the users of the production process and ensure active participation in the society starting from the women＇s economic initiatives, but it cannot be considered as a micro-economic factors in the economy to facilitate an effective financial mechanism. Many studies in the literature have revealed that women＇s contribution to family income of households in poverty has created an important support. In addition, micro-credit system encourages women to create their own jobs, as the GNP （Gross National Product） of the countries contribution to increase employment opportunities. There are opinions arguing that, making use of the contact with communities in the potential female workforce satisfactory for women to create job opportunities to gain income is able to provide initial capital to the existing banking system, because in many countries＇ negative socio-cultural conditions, competing with men is much difficult. Micro-credit system, in the respect of changing countries socio-cultural and socio-economic structures is an important contribution. Microfinance occurred in recent years by rapid developments in Turkey since 2000, progress has been very professional. Our work in the field of micro-finance started operations in 2002, the Evaluation of Women＇s Work Association of Business Economics and the Grameen Bank realized Maya model adapted for Waste Prevention Foundation of Turkey should apply micro-finance. Micro-finance practices in the world and Turkey also compared practices. Turkey＇s application of micro-finance in banks＇ credit policies that support marketing activities related to marketing and sales strategies was examined by size. Also, emerging areas in Turkey, especially in the south-east region, the application of micro-finance loans contributed to the development of this geographical area were assessed. Studies of marketing and financial aspects of micro-finance were examined, the economic dimension of these practices by the country＇s social, cultural, political development has also been found to contribute significantly.展开更多

While these ...Global governance is often equated with international institutions such as the United Nations and the World Bank that were established after World War II to address problems transcending national borders. While these institutions incorporate norms of representative democracy that evolved in national societies, their legitimacy is often questioned on grounds of limited effectiveness and remoteness from the citizens they purportedly serve. The arguments of many democratic theorists that deliberation among ordinary citizens can legitimize policies that heed these views thus bear important implications for global governance. In this paper, the possibility and different ways that civil society enhancing public participation, transparency and accountability in global governance are addressed. The empirical focus will be on the world＇s first global deliberation--WWViews （world wide views on global warming） that was held in 38 countries with all inhabited continents in 2009. The social drivers that encourage innovation in global democratic governance are analysed, as the main successes and challenges of WWViews and sketch three scenarios of the future of deliberative global governance are based on the experiences and plans around global citizen participation. The authors argue that despite some challenges, such as ensuring high quality of deliberation in highly variant policy cultural contexts and building policy pathways conducive to political impact, the prospects of deliberation in helping solve global environmental and policy problems are high, and likely to see cumulative progress in the near future.展开更多

Methods： According to a fully randomized design, 18 goats were evenly divided into three groups： normal bone control group （Group A）, autologous bone group （Group B） and experimental group （Group C）. Each goat in Groups B and C were subjected to the periosteum and bone defect at middle-lower part of the right tibia （20% of the whole tibia in length）, followed by autologous bone or DPB plus autolognus MSCs ＋ rhBMP2 implantation, respectively and semi- ring slot fixation; while goats in Group A did not perform osteotomy. At 24 weeks after surgery, biomechanical tests were carried out on the tibias. Results： At 24 weeks after surgery, the results of anticompression test on tibias in three groups were recorded by a functional recorder presented as linear pressure-deformation curve. The shapes of the curves and their change tendency were similar among three groups. The ultimate pressure values were 10.74 MPa±1.23 MPa, 10. 11 MPa±1.35 MPa and 10.22 MPa±1.32 MPa and fracture compression rates were 26.82%±0.87%, 27.17%±0.75% and 28.22%±1.12% in Groups A, B and C, respectively. Comparisons of anti-compression ultimate pressures and fracture compression rates among three groups demonstrated no significant difference （PAB=0.415, PBC=0.494）. Three-point antibend test on tibias was recorded as load-deformation curves, and the shapes of the curves and their change tendency were similar among three groups. The ultimate pressure values of the anti-bend test were 481.52 N±12.45 N, 478.34 N±14.68 N and 475.62 N±13.41 N and the fracture bend rates were 2.62 mm±0.12 mm, 2.61 mm±0.15 mm and 2.81 mm±0.13 mm in Groups A, B and C, respectively. There was no significant difference between groups （PAB=0.7, PBc=0.448）. The ultimate anti-torsion torque values were 6.55 N.mi-0.25 N.m, 6.34 N＇m^0.18 N＇m and 6.42 N＇m^0.21 N＇m and fracture torsion rates were 29.51°±1.64°, 28.88±1.46° and 28.81°±1.33° in Groups A, B and C, respectively. There was no significant difference between groups （PAB=0.123, PBc=0.346）. Conclusions： The biomechanical characteristics of newly formed bones from heterogeneous DPB for repairing large segmental long bone defect are comparable to those of normal bones and autologous bones. DPB has the potential for clinical usage as bone graft material.展开更多
