Enhancing the supply efficiency of basic public services is helpful to improving people ’s livelihoods. It is an effective way to improve the supply level of basic public services and life quality of residents. Taking 15 counties in the Three Gorges Reservoir Area as examples,the three-stage DEA method is used to calculate the supply efficiency of basic public services in the Three Gorges Reservoir Area. The results show that: the overall supply efficiency of basic public services affected by scale efficiency in the Three Gorges Reservoir Area is relatively low,and the low supply efficiency of basic public services could restrain the level and quality of the supply of basic public services. At the same time,it is also influenced by economic development level,financial self-sufficiency,population density,urbanization level and other environmental variables that caused regional heterogeneity in the supply efficiency of basic public services in different counties.
Generally,it is considered that the conventional deflationism is opposite to the correspon-dence theory of truth,while such deflationary theory is flawed. This article focused on the diversified development of deflationism in the last twenty years. On the basis of elabotating the robust deflation-ism,anti - deflationism,weak deflationism,dialectic defaltionism,it pointed out that we must seek for a new one on the premise of consistency and make it to reflect the essence of truth more objectively.
This essay explored the reasonable path to the development of juvenile community correction system of China on the theoretically basis of parens patriae and by focusing on the difference between the confirmation of juveniles and that of adults on penalty to widen the scope of the subjects of the juvenile community correction and set up independent juvenile community correction institutions by complying with the relevant specialized legislation to construct a juvenile community system with government-led,community involvement,diversified supervision assisted by the judiciary,and step arrangement according to many existing issues in our juvenile community correction system,such as the absence of correcting the bad behaviors,the limits on correcting the serious misconducts,the defects in the subsequent correction of juveniles with the decision of not to prosecute,the issue that the juvenile community correction becomes a mere formality and so on.
Chinese sentencing problems have been experienced a developing process from substantive law priority to procedure law priority. America sentencing guidelines is estabished on the clear rela-tionship between conviction and sentencing. Without clarifying the relationship between conviction and sentencing and that the state supreme judicial organs promote the reform of independent sentencing procedure,it is inevitable that the effect of sentencing procedure reform is not unsatisfying. We can clarify the relationship between convictions and sentencing clearly from the view that penalty has two functions of punishment and education,among which the punishment function of penalty can be a-chieved through conviction to decide the amount of retribution punishment,and the education function of penalty can be achieved through the sentencing decision to decide the amount of declaration punish-ment. The amount of retribution punishment of every crime shall be made by the state supreme judi-cial organ according to the criminal policy of“temper justice with mercy”.
The process of coastal resources essence intergenerational configuration was described from microscopic intergenerational transfer view,and we realized that only achieve intergenerational transfer balance of coastal resources value,can intergenerational equity of coastal resources be truly achieved.On this basis,by logical deduction and verification,we draw that controlling to equal the unit coastal resources price growth rate( excluding inflation leads to price increases) and the skill levels progress speed of development and utilization of coastal resources in the port can achieve intergenerational equity of coastal resources.
Based on the realization of the national prosperity,rejuvenation and the people's happiness,Chinese dream was proposed. It fully embodies the essence of Marxist humanistic thought,which are historicity,practicality,sociality and richness. No matter from its deep connotation,or from its language expression,it both reflects the new development of Marxist human essence theory.The proposing of Chinese dream makes the theory more epochal,and promots the process of its popularization,and satisfies the new needs of spiritual development of the mass of the population.
