The resultant data were subjected to multivariate techniques---Principal Component Analysis (PCA) and Canonical Correspondence Analysis (CCA). Analyses of water parameters with PCA revealed that the first PC axis (PC 1) accounts for maximum variance in the seasonal data, explaining a variability of 91%. The PCA revealed that the seasonal variability in water parameters was due to the wet and dry cycle of seasons and the stations were distinguished on the basis of transparency and turbidity. Zooplankton abundance was dominated by copepods followed by cladocerans. Temporally, abundance of copepods reached a maximum during Post-monsoon (POM) (3 880 ind./L). Spatially, $6 was found to be most abundant of the other stations in zooplankton. Copepodites and nauplii larvae were the major components of zooplankton. The Rotifera were the least abundant among the three zooplankton groups. Brachionus formed the major component of Rotifera zooplankton at all the stations during the study period. In the Cladocera, Macrothrix was present during all the four seasons, while Pleuroxus, Oxyurella, Kurzia and, Diaphanosoma were rare. The CCA shows that maximal temporal variability in zooplankton abundance was explained by temperature and rainfall. ANOVA revealed no significant difference in mean zooplankton abundance among the seasons, but there was a statistically significant difference among the sites.展开更多

The holisticity of governance is reflected in the unity and coordination between value rationality and instrumental rationality, normative appeal and practical appeal as well as global governance and state governance. Global and state governances are two strategic considerations in contemporary China. Actively participating in global governance and rationally promoting state governance is the rational choice of contemporary China, which plays a unique and significant role in realizing the social transformation and national rejuvenation and modernization of contemporary China. Deepening state governance with the help of global governance and promoting global governance with the support of state governance is the basic idea and dimension of understanding and grasping the interaction, coordination and overall planning between the two. The restrictions and effects of global governance on state governance are mainly reflected in such considerations as objects, mechanisms, concepts and interests of governance, and modernization of state governance system and improvement of governance capacity can promote and deepen global governance in a more effective way.展开更多

In the West, property rights have the economic function of maximizing efficiency and the political function of rights protection, but in China, they also have a strong social character. With the modernization of national governance, these functions interact with and transform each other. When the state's ability to supply public goods is relatively weak, property rights take on more of a social character, meeting public demand for welfare at the grassroots level. When the state is better able to provide public goods, the social function of property rights lessens as their economic function grows. The social character of property rights was the institutional foundation for China, as a huge agrarian state, to realize "governance through inaction," and at the same time was the secret key that could break the code to the millennial continuity of Chinese agrarian civilization. Reforms including the collectivization of rural property rights after 1949, the "separation of two rights" (to collective ownership and household contracted land, with a focus on the latter), and the "separation of three rights," (to collective ownership, household contracts and revitalized land management). These changes constitute a process in which the economic function of property rights has been growing while their social character has lessened under conditions of national governance modernization.展开更多

However, very little research has been undertaken on the relationship between state governance and global governance. In an interdependent world where domestic and international boundaries are becoming ever more blurred, state and global governance are not just mutually connected and consistent; they also influence and constrain each other. This paper looks into the influence of state governance on global governance in terms of the differences and internal linkages between state and global governance, arguing that enhancing governance capacity is an effective way for China to participate in global governance, promote the transformation of global governance system, wield its influence as a major power, and boost its right of discourse.展开更多

Over the past few years HIV has been spreading rapidly in the popula- tion. Almost, everyday there are thousands of new human cases of HIV infection being recorded in the world and these occur in almost every country of the world. However, the spread of HIV is relatively faster in the developing countries as compared to developed countries because developing countries have limited resources. Worldwide, 70% of HIV infections in the adults have been transmitted through heterosexual contact and vertical transmission accounts for more than 90~ of global infection in infants and children. In this paper, we propose a nonlinear mathematical model to study the spread of HIV by considering transmission of disease by heterosexual contact and vertical transmission. A stage structured model is proposed and analyzed by considering the total population variable and dividing the whole population under consideration into three stages: chil- dren, adults and old. Also, in this paper it is assumed that the rates of recruitment are different in different groups of population. Equilibria of the model and their stability are also discussed. Using the stability theory of differential equations and computer simu- lation, it is shown that due to the increase in the awareness of the disease in the adult class the total infective population decreases in the region under consideration.展开更多
