The Historic Achievements of the Communist Party of China in Respecting and Protecting Human Rights in the New Era

In the new era,the Communist Party of China(CPC)has made historic achievements in respecting and protecting human rights.Building upon the principle of the“two integrations”(integrating the basic tenets of Marxism with China’s specific realities and fine traditional culture),it has nurtured new theories on respecting and protecting human rights in the new era,which can address the fundamental questions of whom and what the human rights protection efforts in the new era are for.Guided by the principle of“taking our own path,”it has charted a distinct course for the development of human rights,diverging from the Western approach.The CPC has maintained the unity between Party leadership and the respect for and protection of human rights,promoting progress in human rights through the pursuit of“high-quality development,”and ensuring various fundamental rights of the people through the rule of law.Building upon the past experience,the CPC has established the“source”of the institutional framework for respecting and protecting human rights in the new era,crafted the“body”of this institutional framework,and introduced its practical“application.”In promoting the comprehensive advancement of human rights protection,the CPC has facilitated the connotative development of human rights protection in China,empowering China in international human rights discourse,and contributing Chinese strength and wisdom to global human rights governance.

Protection and Development Strategies of Historic Town——A Case Study of the Ancient Daxu Town,Guilin,China

Historic town was stressed as an important base of succeeding local cultures and characteristics,features and modes of protecting and developing historic towns in China were studied and summarized.By taking the Ancient Daxu Town for an example,the protection of this ancient town was introduced,and deficiencies of its development were pointed out as:loss of "original" behaviors of the locals,commercial acts replacing "original" folk customs,incomplete tourist facilities,shabby traditional settlements and so on.In view of this,strategies for protecting and exploring the ancient town were proposed:properly making protection,construction and tourism planning,determining the direction of functional shift,realizing organic renovation of the old town,enhancing the planning and construction of tourist facilities,promoting the sustainable development of the ancient town;expanding the chain of tourism industry,strengthening regional integration;encouraging the locals to participate into the protection and development;applying the operation mode of "supervised by government,operated by enterprises,participated by locals".

Adaptive-Reuse of Historic Industrial Buildings and Sites in China

The paper analyzes the definite place of industrial building in the history of urban development. Due to the development of urban economy and the transition of the traditional industrial structure, many historic cities and towns both at home and abroad have witnessed a large scale "demolition" and abandonment of industrial buildings in urban renewal during last 30 years. Consequently, it has been leading to the discontinuity of urban cultural and historic context. The paper discusses and expounds the clas...

Protection of Historic and Cultural Heritage in the Urban Renewal of Xi'an City,China

Concept of urban renewal was elaborated,which for the protection of historic and cultural heritage not only provides a favorable opportunity of integrating neighboring environment and improving protection conditions,but also imposes threats such as destroying its historic images and patterns,degrading of survival environment.To properly protect historic and cultural heritage in the unceasing urban renewal,and make it a significant resource and feature of the city but not a barrier of urban development,empirical analysis and theoretical research were adopted to analyze and study current conditions and problems of the protection of historic and cultural heritage in Xi'an City from the dimension of urban renewal concept and present urban renewal of Xi'an.Moreover,through summarizing successful experience of other regions,specific strategies were given to protect historic and cultural heritage of Xi'an City in its urban renewal more scientifically and reasonably.

On Montrose's Perception of New Historicism

Louis Adrian Montrose has addressed literary,historical,and theoretical topics and issues concerned with New Historicism.He elegantly demonstrated how language and literary imagination shape cultural value;belief,and understanding;social distinction and interaction;and political control and contestation,thus significantly shaped contemporary studies of poetics and politics of culture.He refuted the oversimplified polarization of language and society of J.Hillis Miller and Edward Pechter's misunderstandings about "New Historicism" and stated his own understanding and expectations of New Historicism.From a detailed analysis of his ideas,the author points out the weakness in his arguments and advises researchers in this field to dialectically view the school of New Historicism.

Implications for Cultural Landscape in a Chinese Context: Geo-analysis of Spatial Distribution of Historic Sites

The protection of historic sites, especially their relationship with urban development, has become a worldwide issue, both in developed and developing countries. In the context of rapid urbanization in China, the realistic compatibility between urban construction and the protection of historic sites is always a key research topic. In this study, first, to comprehend their spatial distribution patterns, 828 historic sites throughout the country are selected based on certain criteria. Then, we conduct quantitative research using GIS software, adopting indicators that include Nearest Neighbor Index, Gini Coefficient, and Geographic Concentration Index to analyze the spatial characteristics of historic sites on the three levels of city, province and nation. The results indicate that the spatial distribution of the different types of historic sites is an agglomeration on the nationwide scale, most of which is located in the regions of the Pearl(Zhujiang) River Delta, Yangtze(Changjiang) River Delta and Beijing-Tianjin Region. Because the majority of historic sites are located within approximately 10 km of the downtown area, a certain pattern has emerged, showing that the larger cities own more historic areas, which are in a more incomplete state of preservation, indicating the fragmentation of heritage spaces. The formation mechanism of the historic sites' distribution pattern is based on the conditions of the cities/towns as well as the bid-rent theory.

Exploring Location Pattern of Commercial Stores in Shichahai, Beijing from a Street Centrality Perspective

The location pattern of different commercial stores in Shichahai, a historic conservation area in Beijing, was investigated from a street centrality perspective. Many previous studies have investigated the relationship between street centrality and land use patterns or commercial activities at interurban or intraurban scales. We considered Shichahai in this study to determine if street centrality applied at the street scale and if the street network was the only factor influencing the selection of store location. First, the nearest neighbor index, nearest neighbor hierarchical spatial cluster(NNHSC), and kernel density estimation(KDE) methods were used to provide baseline spatial distributions of commercial stores. Second, urban network analysis(UNA) tools were used to measure the street centrality indices under two conditions, with and without the weighting of cultural relics calculated by a principal component analysis(PCA). Finally, both store locations and centrality values at nodes were transformed to one unit(raster pixel) for a correlation analysis.The results showed that three of the four store types were clustered and had their own hotspots that were mostly located in the eastern and central parts of city blocks. The most momentous findings were determined from the street centrality indices. Among the three store types with correlation coefficients above 0.5, all centrality indices with landmark weighting, except straightness, had higher correlations,with closeness with landmark weighting having the highest correlation, followed by betweenness with landmark weighting. Therefore,we statistically concluded that street centrality could apply at the street scale and that the street network was not the only factor that influenced store location pattern, with landmarks also playing a significant role. The results provide guidance in determining the selection strategy for stores in a historic conservation area.

Dynamic response analysis of train-induced vibration impact on the Probhutaratna pagoda in Beijing

Train-induced vibration exhibits a potential dynamic impact on historic buildings and especially on those with high historical and cultural value.Under the long-term reciprocating load of train vibrations,structural fatigue damage can occur,and thus,a significant problem involves effectively evaluating and mitigating vibration impact on historic buildings while developing a rail transit system.In the present study,train-induced vibration impact and dynamic behavior of Probhutaratna pagoda in the suburb of Beijing,which has a history of approximately 1000 years,was investigated.To examine the dynamic behavior of the Probhutaratna pagoda and determine the weakest position in its architectural damage under train loads,its dynamic characteristics were measured.The free vibration modes were identified based on the dynamic measurement results.Subsequently,a finite element(FE)model of the Probhutaratna pagoda was constructed and the models and train-induced structural responses were compared with measured results.Finally,the structural dynamic responses to moving train loads were analyzed in detail.The results indicate the following conclusions.(1)The dominant frequency of the ambient vibration is below 4 Hz,and the dominant frequency of the train-induced vibration is between 8 and 16 Hz.(2)The first,second,and third order natural frequencies are 1,3.25,and 6 Hz,respectively,in the west-east direction,and are 1,3.25,and 6.25 Hz,respectively,in the north-south direction.(3)The two weakest locations(A and B)of the Probhutaratna pagoda are observed at the spire bottom and west gate of the first floor.At location A,the maximum principal stress reached 243.6 N/m^2 and the corresponding maximum tensile strain reached 3.74×10^-7.

Ancient DNA of the pygmy marmoset type specimen Cebuella pygmaea(Spix,1823)resolves a taxonomic conundrum

The pygmy marmoset,the smallest of the anthropoid primates,has a broad distribution in Western Amazonia.Recent studies using molecular and morphological data have identified two distinct species separated by the Napo and Solimoes-Amazonas rivers.However,reconciling this new biological evidence with current taxonomy,i.e.,two subspecies,Cebuella pygmaea pygmaea(Spix,1823)and Cebuella pygmaea niveiventris(Lönnberg,1940),was problematic given the uncertainty as to whether Spix’s pygmy marmoset(Cebuella pygmaea pygmaea)was collected north or south of the Napo and Solimoes-Amazonas rivers,making it unclear to which of the two newly revealed species the name pygmaea would apply.Here,we present the first molecular data from Spix’s type specimen of Cebuella pygmaea,as well as novel mitochondrial genomes from modern pygmy marmosets sampled near the type locality(Tabatinga)on both sides of the river.With these data,we can confirm the correct names of the two species identified,i.e.,C.pygmaea for animals north of the Napo and Solimoes-Amazonas rivers and C.niveiventris for animals south of these two rivers.Phylogenetic analyses of the novel genetic data placed into the context of cytochrome b gene sequences from across the range of pygmy marmosets further led us to reevaluate the geographical distribution for the two Cebuella species.We dated the split of these two species to 2.54 million years ago.We discuss additional,more recent,subdivisions within each lineage,as well as potential contact zones between the two species in the headwaters of these rivers.
