摘要：
Cerebral morphological abnormalities in major depressive disorder (MDD) may be modulated by antidepressant treatment and course of illness in chronic medicated patients. The present study examined cortical thickness in patients with untreated first-episode MDD to elucidate the early pathophysiology of this illness. Here, we examined cortical thickness in patients with first-episode MDD (N=27) and healthy controls (N=27) using an automated surface-based method (in FreeSurfer). By assessing the correlation between caudate volume and cortical thickness at each vertex on the cortical surface, a caudate-cortical network was obtained for each group. Subsequent analysis was performed to assess the effect of anhedonia by the Temporal Experience of Pleasure Scale. We observed increased cortical thickness at the right orbital frontal cortex and the left inferior parietal gyrus in MDD patients compared with healthy controls. Furthermore, morphometric correlational analysis using cortical thickness measurement revealed increased caudate-cortical connectivity in the bilateral superior parietal gyrus in MDD patients. All changes were not related to anhedonia. These preliminary findings may reflect disorder manifestation close to illness onset and may provide insight into the early neurobiology of MDD.

摘要：
Environmental management and sustainable financial growth are currently hot topics in academic research. This article examines the relationships among environmental management, debt financing, and sustainable financial growth in the Chinese tourism industry. The results show that environmental management and debt financing have promoted sustainable financial growth, and the overall effect of debt financing on sustainable financial growth has been affected by environmental management. After employing different methods of controlling the endogeneity, these conclusions are still robust. We also examine the mediating effect and threshold effect on environmental management, debt financing, and sustainable financial growth, and the results reveal that debt financing can mediate the effect of environmental management on sustainable financial growth and that there is nonlinear impact of debt financing on sustainable financial growth in different thresholds of environmental management. The analysis results show that the presented policy proposals promote the development of tourism companies from the aspects of debt financing and environmental management.
摘要：
The paper has studied the beneficial segmentation status of vegetable consumption market with the statistical methods of factor analysis and cluster analysis. Its purpose is to promote the development of vegetable industry and its marketing strategy in Hunan province by deeply exploring the purchasing behavior and demography characteristics of vegetables purchasers in different segment market. The results indicate that the impact affecting on the purchasing behavior of vegetable consumers in Changsha city acts mainly in six categories, namely "producing area", "security", "taste", "facilitate", "Variety", "appearance". Cluster analysis further revealed that the vegetable consumption market in Changsha City could be broken down into the consumer market for taste-type, security- type consumer market, convenience- type, visual- type and diverse consumer market- type consumer market.

HTBF's growth;venture capital;the government
摘要：
Compared with the big enterprise and the mature enterprise, the high technology-based firm (HTBF) lacks the innovation capabilities and restricts the fast and sustainable growth. Lacking the support of exterior financial capital is an important reason. Under the mature market conditions, HTBF depends upon the good operation of venture capital(VC) and the support of capital market for obtaining the power of innovation, but at present this is only an ideal plan in China, where lacks the effective system security and market environment. Therefore, the paper mainly analyzes the growth characteristics of HTBF backed venture capital, thereby proposing an interaction mechanism between venture capital and HTBF.
摘要：
Hunan is a major tobacco export province in China. This paper focuses on the international competitiveness of Hunan tobacco. Firstly, we evaluate its competitiveness in achievement by using CMS model and index of RCA, and find that Hunan tobacco had comparatively strong international competitiveness. But compared with the other main exporting commodities, its international competitiveness presented a downward tendency. Then, its competitiveness in strength is analyzed from the angle of the ratio of export and import price, and the conclusion is that the international competitiveness of Hunan tobacco mostly came from the low price. Further, we discuss its competitiveness in potential based on the diamond model of Michael Porter, and find that Hunan tobacco had certain comparative advantages in soil, labor force, related & supporting industries and domestic demand, but at a disadvantage in policies and technologies. At last, this paper supplies some crucial methods to improve and preserve the competitiveness of Hunan tobacco.
