In the present case,we propose the novel generalized fractional integral operator describing Mittag-Leffler function in their kernel with respect to another function Φ.The proposed technique is to use graceful amalgamations of the Riemann-Liouville(RL)fractional integral operator and several other fractional operators.Meanwhile,several generalizations are considered in order to demonstrate the novel variants involving a family of positive functions n(n∈N)for the proposed fractional operator.In order to confirm and demonstrate the proficiency of the characterized strategy,we analyze existing fractional integral operators in terms of classical fractional order.Meanwhile,some special cases are apprehended and the new outcomes are also illustrated.The obtained consequences illuminate that future research is easy to implement,profoundly efficient,viable,and exceptionally precise in its investigation of the behavior of non-linear differential equations of fractional order that emerge in the associated areas of science and engineering. 展开更多

With the methods of qualitative analysis, induction and deduction, modes of key links in increase and decrease connection of urban and rural construction land are proposed in view of the involved three key links, namely reclamation of rural construction land, fund raising and management of connection turnover index, based on the comprehensive analysis of political connotation in increase and decrease of urban and rural construction land. The modes include "village relocation and combination", "hollow village" reconstruction, high-rise stereo, village relocation in the mountain and related capital raising and turnover index management and the applicable regions of various modes are analyzed and studied. The research result provides reference for the reasonable operation of increase and decrease link of urban and rural construction land. 展开更多

Industrialization and urbanization are the most dominant causal factors for long-term changes in surface air temperatures. To examine this fact, the long term changes in the surface-air temperatures have been evaluated by the linear trend for the different periods, i.e. 1901-2013, 1901-1970 and recent period 1971-2013 as rapid industrialization was observed during the recent four decades. In the present study, seasonal and annual mean, maximum and minimum temperature data of 36 stations for the period 1901-2013 have been used. These stations are classified into 4 groups, namely major, medium, small cities and hill stations. During the period 1901-1970, less than 50% stations from each group showed a significant increasing trend in annual mean temperature, whereas in the recent period 1971-2013, more than 80% stations from all the groups except small city group showed a significant increasing trend. The minimum temperature increased faster than that of the maximum temperature over major and medium cities, while maximum temperature increased faster than the minimum temperature over the small cities and hill stations. The annual mean temperature of all the coastal stations showed a significant increasing trend and positive correlation with Precipitable Water Vapour (PWV). The effect of PWV is more pronounced on minimum temperature than that of the maximum. 展开更多

In order to explore the differences of projects on linking newly-added cropland quotas with the amount of land used for construction in targeted poverty alleviation in different rural areas,this paper selects the social,economic,cultural and ecological evaluation indexes,and introduces the AHP method,to measure the benefits before and after the implementation of the four typical projects on linking newly-added cropland quotas with the amount of land used for construction in Xinjiang. The results show that after the implementation of the project,the social,economic,cultural,ecological and comprehensive benefits of each region have been improved,but the benefits of regions with different economic levels are significantly different. This paper holds that the projects on linking newly-added cropland quotas with the amount of land used for construction in different regions should be considered from the ultimate goal before the establishment and implementation of the project,so as to realize the win-win situation between the urban-rural requisition-compensation balance and the targeted poverty alleviation in rural areas. 展开更多

From the perspective of balancing urban and rural development,this article researches the factors influencing the consumption level of rural residents in China.I select the relevant data concerning per capita net income of rural households and annual per capita consumer spending of rural residents for living in the period 1985-2008,establish the regression model of per capita net income of rural households and per capita consumer spending of rural residents for living,and conduct regression analysis and error correction model test using the measurement software.The analysis results show that there is not only long-term equilibrium relationship between rural residents' current consumption and rural residents' current income,between rural residents' consumption in lag period 1 and rural residents' income in lag period 1,but also short-term equilibrium relationship;current income is the main reason for determining the current consumption).Corresponding proposals are put forward to promote the level of rural consumption in China as follows:propel agricultural modernization;actively develop specialized cooperative organizations of rural residents;improve rural land transfer mechanism;promote the level of public services in rural areas;accelerate the transfer of rural surplus labor. 展开更多

For needed changes to occur, we need to do gender in higher education and tenure differently. The way that tenure is established and reviews for tenure are conducted need to be based more on a system that allows for the development of the whole individual. The future health of academia rests on the development and refinement of a system that creates a healthy environment for all members of that system. All faculty members cannot and should not be held to standards that were created in another time, which constructed the academic role as a gendered role. Individuals need to consider how we do gender, and how that creates an impact on our organization, academia. A process for equitable review of all participants in the system requires that all individuals be involved in the process of defining the standards for a tenurable professor. Then all voices should and must be represented when we construct how we do tenure so that even minority voices still have their chance to speak. There is a better way to perform the roles we take in academia, there is a better way to perform our gender in this setting, and from recognizing this we can then move to a better way to do all this that is academia. 展开更多
