Factors such as environment,capital and technology produce an effect on sustainable economic growth.This paper develops and characterizes how resource-consuming Industry achieves steady-state path of economic growth,under consideing the impact of environmental pollution and the accumulation of human capital input about technological progress,including re-use of original resources and Industrial pollution control.Finally,this paper analyses how industrial economic growth is effected by pollution control and resource recycling and reuse caused by technological progress.
Two urostylid ciliates, Trichototaxis marina Lu et al., 2014 and Uncinata bradburyae (Gong et al., 2001) Luo et al., 2015, new to Japan, were collected from coastal water in Nagasaki. Both were identified based on live and protargol-stained specimens. Morphologically, two new populations of T. marina correspond well with the type population in the live morphology and ciliature, especially a very flexible body having a long elliptical shape, and reddish cell colour caused by irregularly shaped pigments, multiple left marginal rows and marine habitat. A few morphological features were supplemented for the species. The Japanese population of Uncinata bradburyae presents the diagnostic features, especially the presence of an anterior snout-like procession and the elongated membranelles in the proximal portion of adoral zone, orientation of the anterior portion of the left marginal row, highly developed transverse cirri, and high number of dorsal kineties derived from two unique, de novo formed anlagen. Additionally, greenish pigments were first documented for the species. The new record suggests U. bradburyae might be a eurythermal species. The overall pattern of the divisional events resembles that of the Qingdao population described previously. Part of the reorganisation was also first revealed for U. bradburyae, which corresponds to the divisional processes in the opisthe. The present study corroborates the wide distribution of both species, and contributes to circumscribe the species by expanding the range of some morphometric data.
The seventh five-year period plan,ratified in principle and publicized on the Forth Session of the Sixth National People's Congress in 1984,introduced the concepts of the eastern,central and western region and divided China into three major economic regions.This division roughly described the hierarchical map of economic and social development in China and objectively reflected the trends in economic and social development in different regions.After more than 20 years of development,however,its limitations are emerging and unsuitable for today's development.This division cuts off the horizontal linkage of watershed economy,results in the lack of environmental resource compensation,and does not accord with the physical geography of China.It is not good for regional economic integration,resulting in unclear responsibility of central cities for leading the development of the western region and widening gap between the eastern and western region.Against this background,the absolute difference between cities in the eastern region and countryside in the western regions has further expanded.To change the Mathew effect of the rich-poor gap requires a rethink of regional economy.
The impact of taxation on labor supply depends on the income effect and substitution effect after taxation. However, the two effects will be different under various tax systems. This paper intends to analyze the impacts of personal income tax on labor supply of urban dweller under Chinese tax system. This paper use theoretical and empirical analysis method to analyze this problem. We conclude that the income effect is greater than substitution effect under in China, and then we put forward some relevant suggestions.
As technology advances, digitalization has become more and more widespread. This is true of the continuation and inheritance of intangible cultural heritage in which digital technology is also increasingly utilized. For one thing, the contents of intangible cultural heritage that are difficult to preserve need to be refined for technological presentation. For another, the emotional connotation of intangible cultural heritage implied in the inheriting process should be retained as far as possible. This paper discusses that how digital technology broadens the path of inheriting intangible cultural heritage, analyzes the logical connection between the protection of intangible cultural heritage and digital technology, and also explores the future of developing intangible cultural heritage with the help of digital technology.
Abstract Background: The taxonomy of tintinnine ciliates is vastly unresolved because it has traditionally been based on the lorica (a secreted shell) and it has only recently incorporated cytological and molecular information. Tintinnopsis, the most speciose tintinnine genus, is also the most problematic: it is known to be non-monophyletic, but it cannot be revised until more of its species are studied with modern methods. Results: Here, T. hemispiralis Yin, 1956, T. kiaochowensis Yin, 1956, and T. uruguayensis Balech, 1948, from coastal waters of China, were studied. Lorica and cell features were morphometrically investigated in living and protargol-stained specimens, and sequences of three ribosomal RNA (rRNA) loci were phylogenetically analyzed. The three species show a complex ciliary pattern (with ventral, dorsal, and posterior kineties and right, left, and lateral ciliary fields), but differ in lorica morphology, details of the somatic ciliature and rRNA gene sequences. Tintinnopsis hemispiralis is further distinguished by a ciliary tuft (a ribbon of very long cilia originated from the middle portion of the ventral kinety and extending out of the lorica) and multiple macronuclear nodules. Both T. kiaochowensis and T. uruguayensis have two macronuclear nodules, but differ in the number of somatic kineties and the position of the posterior kinety. Two neotypes are fixed for T. hemispiralis and T. kiaochowensis to stabilize the species names objectively, mainly because of the previous unavailability of type materials. By phylogenetic analysis and comparison with closely-related species, we infer that the ciliary tuft and details such as the commencement of the rightmost kinety in the lateral ciliary field are synapomorphies that may help clarify the systematics of Tintinnopsis -like taxa. Conclusion: The redescriptions of three poorly known Tintinnopsis species, namely T. hemispiralis , T. kiaochowensis , and T. uruguayensis firstly revealed their ciliary patterns and rRNA sequences. This study expands knowledge and database of tintinnines and helps in identifying potential synapomorphies for future taxonomic rearrangements.
The fragile tourism is vulnerable to a variety of crisis events, effect of which becomes a hot issue of tourism research.According to 1995--2014 Sinkiang tourism statistics, this paper will build a background trend line of domestic tourist arrivals and income, and assess the effect of crisis events on Sinkiang domestic tourist economy, in order to provide decision making basis for perfecting tourism crisis forewarning management mechanism.
