Regional Difference in Social Capital and Its Impact on Regional Economic Growth in China

Social capital has played an increasingly important role in regional development.China is a country with high stocks of social capital.Using several different indicators of social capital,this study tries to research the regional disparities in social capital and the influence of social capital on economic growth of China in 1978-2004.Measuring social capital with indicators of associations,charities and blood donation rates,this study finds significant regional disparities in social capital at provincial level in China.Those indicators for social capital are highly correlated with regional economic performance.Statistical analysis shows that social capital has a significant and positive effect on a long-term provincial economic growth.This relationship exists after controlling policy,macro location factors,and per capita GDP in the initial year.The empirical findings indicate that institutions,culture and social relations are critical for regional development in China.Therefore,the creation and support of social capital should be paid more attention to when making regional policy.

Overexpression of connective tissue growth factor WISP-1 in Chinese primary rectal cancer patients

AIM： To clarify the expression change of Wnt-induced secreted protein-1 （WISP-l） in human rectal cancer and to determine whether it is correlated with invasion and metastasis of human rectal cancer.METHODS： Eighty-six paired samples of rectal cancer and surgically resected distant normal rectal tissue were collected and allocated into cancer group and control group respectively. WISP-1 mRNA was detected by relative quantitative real-time RT-PCR and WISP-1 protein was examined by immunohistochemical staining.RESULTS： WISP-1 gene overexpression was found in 65% （56/86） primary rectal cancers, 2-30 times that of the level in normal matched rectal tissues （P = 0.001）. The mRNA expression level was correlated with Duke＇s staging, histological differentiation grade and lymph node status. The WISP-1 protein expression was in accordance with mRNA expression level. The positive degree of immunohistochemical staining in the cancer group （1.40±0.35） was different from that in control group （1.04± 0.08, P 〈 0.001）. Moreover, in cancer group the positive staining degree in high-level mRNA cancers （1.46 ±0.37, n = 56） was higher than that in low-level mRNA （1.28 ± 0.28, n = 30, P = 0.018）.CONCLUSION： Aberrant levels of WISP-1 expression may play a role in rectal tumorigenesis. WISP-1 may be used as a specific clinical diagnosis and prognosis marker in rectal cancer.

Change of Cultivated Land and Its Implications on Food Security in China

The population growth and demand for high living standard not only increase food demand but also cause more loss of the limited cultivated land resources. Cultivated land loss caused by disasters and the implementation of the ＂Conversion of Cropland to Forest or Grassland＂ project make this situation even worse in China. Thus, there is a problem to be solved imminently that to what extent the cultivated land can guarantee food security of China. Based on time-series data on food production and cultivated land area from 1989 to 2003 and other research results, this paper constructs quality index of cultivated land according to different land quality. Regression models are adopted to predicate changes of main factors from 2004 to 2030, which have great effect on cultivated land area or grain productivity, and verify accuracy with coc^cient of determination （R2）. Nine results were got according to three scenarios of decreasing rate of population growth rate and three cases of urban and rural built-up area per capita. There results show that China＇s food supply can only be maintained at a low to middle level of 370-410kg per capita, that is, China has enough land productivity to meet primary demand of food independently. However, it cannot reach the safe target of 500kg per capita if there is no breakthrough in breeding or no remarkable improvement of irrigation works, when the grain self-sufficiency maintains no less than 80%. To breed productive crops and to improve land productivity by mefiorating low quality cultivated land are appropriate measures to shrink the gap between food demand and supply. The results may offer helpful information for the formulation of policies on population growth, land use, protection of cultivated land.

Population and Environment:Necessary Transition Initiatives for Developing Countries

Now environment is an important topic in academic field.Many researches focus on the negative outcomes of nature which are being continually created by human and much attention has been paid to how the environment is protected through integrated research,movement and policy.But few studies are concentrated on population and environment and are to find out the interconnectivity and underlying mechanism that have an effect on people's preferring additional children and perception to environment.Many researchers claim that population growth is a great problem for environment but they do not provide the indepth integrated knowledge and mechanism that influence fertility trend and environmental problems.It is very crucial to develop practical and concrete initiatives to confirm a transition to reduce population growth and redirect the perception on population and environment.

First evidence of prey capture and meat eating by wild Yunnan snub-nosed monkeys Rhinopithecus bieti in Yunnan,China

Most extant nonhuman primates occasionally prey on fast-moving, warm-blooded animals; however, Indriidae, Lepilemuridae, and Colobinae either scavenged for meat or did not eat meat at all. Here we report six cases of animal consumption by the snub-nosed monkey Rhinopithecus bieti in a wild, habituated group between 2004 and 2009 in Yunnan, China. At present, only males in an all-male unit within the study group were involved in active hunting. Such a male-biased activity may be related to the group structure and spatial spread of R. bieti. Two females were observed eating freshly killed birds. The findings confirmed that R. bieti engaged in scavenging and, when hunting, employed a cranio-cervical bite to kill their prey. Meat eating is likely a nutrient maximization feeding strategy in R. bieti, especially in males. A begging behavior occurred after successful prey capture. Although begging was observed, no sharing of the meat was seen. The present findings illuminate the dietary diversity of R. bieti and their ability to expand their dietary spectrum.

Spatial Pattern Evolution and Casual Analysis of County Level Economy in Changsha-Zhuzhou-Xiangtan Urban Agglomeration, China

In order to evaluate whether or not the county units′ economy in the Changsha-Zhuzhou-Xiangtan(Chang-Zhu-Tan) Urban Agglomeration was growing as expected, this study analyzed the spatial economy pattern at county-level by using the Exploratory Spatial Data Analysis(ESDA) method. In this process, the global Moran′s I and local Getis-Ord G*i indexes were employed to analyze indicators including per capita GDP and three industrials(i.e. primary, secondary and tertiary industry) from 2000 to 2010. The results show that: 1) the county units′ economy in the Chang-Zhu-Tan Urban Agglomeration has exhibited a strong spatial autocorrelation and an accelerated integration trend since 2008(Moran′ s I increased from 0.26 to 0.56); 2) there is a significant difference in economy development between the northern and southern county units in the Chang-Zhu-Tan Urban Agglomeration: the hotspot zone with high economic level was formed among the northern county units whereas the coldspot zone with low economic level was located in the southern areas. This difference was caused primarily by the increasingly prominent economic radiation effect of Changsha ′upheaval′; 3) town density, secondary industry, and the integration policy are the major contributors driving the evolution of the spatial economy pattern in the Chang-Zhu-Tan Urban Agglomeration.

Understanding the Past,Present,and Future of China's Economic Development——Based on A Unified Framework of Growth Theories

Through exploring the limitation of the neoclassical theory of economic growth,which classifies growth as a homogenous process,this paper reconciles various theories of economic development and explains the rises and falls of economic growth under a unified framework,focusing on incentives of the accumulation of physical and human capital.This paper classifies instances of economic growth into four categories—the Malthusian poverty trap,the Lewis dual model of economic development,the Lewis turning point,and Solow neoclassical growth model.This paper conducts empirical analysis of these categories of economic development as they are relevant to Chinese economic growth and discusses policy implications therein.

Why Do Immigration Policies Differ Between Japan and Korea

Foreign immigrants to South Korea are transforming the demographic map of the nation. Survey findings have revealed that the rapid influx of foreigners into South Korea since the year of 2000 has brought about a population increase that has surpassed initial government predictions. In contrast, Japan continues to restrict foreign nationals, in spite of sharp decreasing of national population. But why did such a difference in the respective policies of Japan and South Korea regarding foreign workers and immigration, and citizenship, suddenly come into existence after the year of 2000？ This paper addresses this single question, and answers to the question that the differences of political opportunity structures around immigration policies in these two countries matter. Firstly, in Japan, the business sectors which want to have more immigrants have difficulties in reestablishing the strong relations with ruling parties but South Korean business still keeps the smooth relations with conservative governments. Secondly, Japanese labor unions regard immigrants as a serious threat against their members＇ jobs, but immigrant issues are understood as one of the human rights issues against which unions have to work. Thirdly, anti-immigrants groups in Japan are given chances to bring their message through traditional media such as TVs, but the doors of traditional media are closed for the groups in South Korea.

Impact of Regional Economy on Internal Migration in Yangtze Delta:Based on Panel Data

Metropolitan Shanghai, in Yangtze River Delta (YRD), plays undoubtedly the leading role in the economic development in China, and becomes one of the most important population con- gregation areas. It is also widely regarded as the sixth uprising urban agglomeration in the world. Based on the quantitative stud- ies on basic socioeconomic and demographic profile on the num- ber and transition of population, this paper concluded that the migration is the key factor for population dynamics in YRD. Then, what are the regional economic factors affecting the migration of different cities in YRD? The panel data show that the different wage level is the most important factor that affects the immigra- tion in YRD. Moreover, the ratio of industry sector and service sector has an impact on attracting immigration. However, per-capital GDP and the share of foreign direct investment (FDI) to GDP have dual-side impact: not high per-capital GDP and FDI bring the high immigration.

An Open-Label Study of Pegylated Liposomal Doxorubicin,Vincristine, and Reduced-Dose Dexamethasone Combination Therapy in Newly Diagnosed Multiple Myeloma Patients in the Chinese Population

OBJECTIVE Though doxorubicin is highly active in the treatment of multiple myeloma, its toxicity profile limits its therapeutic index. We performed this study to evaluate the efficacy and liposomal doxorubicin （PLD, Ca of pegylated , vincristine, and reduced-dose dexamethasone combination therapy in newly diagnosed multiple myeloma （MM） patients in a Chinese population. METHODS This was an open-label, single-arm study in which newly diagnosed patients with MM received PLD 40 mg/m2 intravenously on Day 1, vincristine 1.4 mg/m2 intravenously （maximum 2 rag） on Day 1, and 40 mg of dexamethasone （intravenously or orally） from Day 1 to Day 4. Treatment was repeated every 28 days for at least 4 cycles. RESULTS In the intent-to-treat （ITT） analysis, the overall response rate was 68.29%, and the complete remission rate was 10.98%. The incidence of all adverse events was 46.34%. The most common non-hematologic toxicities were palmar-plantar erythrodysesthesia （13.4%） and stomatitis （6.1%）. CONCLUSION PLD, vincristine, and a reduceddose dexamethasone combination （DVd） is an effective and safe regimen in newly diagnosed MM patients in a Chinese population.

Why the Yangzi Delta Did Not Become Industrialized： A Comparative Analysis of Economic Developments in China＇s Yangzi Delta Region and Great Britain

The development of the family-based handicraft industry in the Yangzi delta provided supplementary income and employment opportunities to auxiliary family members. But it did not replace subsistence farming as the primary method in which peasants made their living, and more importantly, it did not allow China to close the gap in the great divergence with the West. So why didn＇t the cotton-based handicraft industry catapult the Yangzi delta region into the modem era of industrialization？ Why did the handicraft industry merely serve as a supplementary rather than an alternative means of livelihood？ To understand the reasons why the handicraft industry did not transform China into an industrial and urban nation, it is important to examine the constraints in which population growth and land intensification had imposed on the peasants of the delta. These factors combined with the favorable geographical environment and commercial opportunities for trade in other regions, forced peasants to adopt the family-based handicraft industry as a supplementary source of income for survival. While the impact-response model may have suggested that it was the inability of the handicraft spinners and weavers to compete against British machines and the subsequent drop in cotton prices, a China-centered approach advocated by Paul Cohen would suggest domestic factors such as rapid population growth due to changes in taxation policies and the diminishing rate of return in labor, and the insufficient production office and grain may have been the real reasons that prevented the handicraft industry from developing into an alternative for farming.
