As one of the main spaces for outdoor interaction in historical and cultural blocks, the improvement of its vitality is of great significance for the improvement of residential environment and the better inheritance of history and culture. Taking Daopashi Street in Anqing City as an example, an evaluation model of landscape spatial vitality of historical and cultural blocks was constructed from three aspects of viewing function, store status and service facilities, and analytic hierarchy process was used to determine the index weight and vaguely evaluate the landscape spatial vitality of historical and cultural blocks. The results show that through the comparison of weight, architectural style(0.317), the practicability of service facilities(0.168) and plant landscape(0.165) had a significant impact on the landscape spatial vitality of historical and cultural blocks,and the landscape spatial vitality of historical and cultural blocks in Daopashi Street in Anqing City was at a good level.展开更多

文摘Urban historic blocks are an important part of urban public space,but urban public space pays far less attention to users’experience,and there is a lack of design problem of experiential theme landscape.The landscape design practice of Shengjin Tower Folk Custom Historical Block in Nanchang provides an attempt to explore the design problem of experiential theme landscape.In this paper,the results of the design practice were sorted out and summarized,and the specific conception of the experiential design of urban public space was discussed from three aspects of the experiential control design,spatial experience design and serial experience design of the historic block on the basis of elaborating the design concept,so as to provide inspiration and reference for similar urban historic block projects.
文摘Pedestrianization is an urban revitalization strategy to enhance sustainability and livability in car-oriented cities.Despite many studies in this research field,the effects of pedestrianization on the economy of cities in developing countries still need further investigation.Additionally,the impact of this strategy on the tenant mix of com-mercial and historical areas in Middle East countries is nebulous.To address these inadequacies,we considered Chaharbagh Abbasi street,located in the heart of Isfahan,Iran,and investigated the impact of a pedestrianization project with particular emphasis on how it affects the economic sustainability of existent commercial fabric.Pre-and post-project data along with field observations and quantifications used to assess structural replacements in trade,were analyzed with SPSS and ArcGIS software.The results revealed unexpected outcomes,such as the closure of some traditional businesses(27.5%),a stagnation in sales(69%)and a decrease in job offers(84%)leading the local economy to a fragile situation.Conversely,it was found that the footfall volume increased by 64% and 73% from the retailers’and pedestrians’viewpoints.This evolution along with a wide opening of food and beverage stores(approximately 60%)makes the post-pedestrianization results more promising than earlier predictions.In conclusion,these findings reinforce the importance of pedestrian streets in revitalizing economic activities in historical and commercial areas from the perspective of economic sustainability.Due to the lack of similar investigations in Middle East countries,these findings can support decision-makers and urban planners to take preventive measures in preserving the diversity of individual small shops for upcoming urban rehabilitation projects in terms of pedestrianization.
文摘Desertification is increasingly serious in Xinjiang,and the construction of water conservancy is a precondition for the development of agriculture.The main project for the development of agriculture and water conservancy in Xinjiang is to build Karez,which played a vital role in the development of Xinjiang agriculture in the Qing Dynasty.It has been recorded many times in historical documents of the Qing Dynasty,such as Lin Zexu s Diary,Tao Baolian s Diary,Xinjiang Atlas and Zuo Zongtang s Memorial to the Emperor,etc.,which recorded the situation and historical origin of Karez.Karez made a significant contribution to the development of agriculture in the Qing Dynasty.It increased the cultivated land in Xinjiang at that time,and increased the types and yields of crops.It is conducive to the stability and development of Xinjiang s economy.Until today,Karez is still an important water source for agricultural irrigation in Xinjiang.

文摘The value implication,main contents and practical dimension of integrating the historical initiative spirit into the ideological and political course of colleges and universities were studied.From the perspective of value implication,integrating the historical initiative spirit into the ideological and political course of colleges and universities is helpful to promoting the integrity and innovation of the ideological and political course in colleges and universities,deepening the historical cognition of students and building the cornerstone of students belief.From the perspective of main contents,teachers of ideological and political course should clarify the theoretical connotation of the historical initiative spirit,give a thorough exposition of the generation logic of the historical initiative spirit,and explain The Times value of the historical initiative spirit lively.From the perspective of practical dimension,it is necessary to give full play to the educational function of the historical initiative spirit by enriching the content of curriculum teaching,innovating the ways and methods of education and teaching,integrating theory and practice,and online and offline interaction.
文摘Karl Marx’s insightful critique of bourgeois rights,represented in the Declaration of the Rights of Man and of the Citizen adopted by France,can be attributed to the short-term and longterm perspectives he adopted successively in his research.By reading works such as History of France in the Revolutionary Era and History of the French Revolutionary Parliament,Marx was able to examine the original intentions of the legislators in the period of the French Revolution.This short-term examination was the most intuitive and logical approach to studying the Declaration of the Rights of Man and of the Citizen,in which Marx focused on the research of the period of the French National Convention and its idea on property rights.The enigmatic political-legal facts that emerged in 1793 during the French Revolution,along with other incidents,presented an opportunity for Marx to turn to long-term rights surveys.In this context,Marx gradually shifted his attention from the legislators who were the shining protagonists of the“grand political historical drama”to the underlying forces that worked behind them,and in doing so understood how the two major achievements of the French Revolution provided an explanation for the historicity of the phenomenon of rights.Marx’s longterm rights surveys from the perspective of historical materialism were directly inspired by the Kreuznach Notes as well as famous scholars including Francois Guizot,Augustin Thierry,and Henri Saint-Simon.
文摘This article delves into the intricate landscape of gender roles within China,employing a historical lens to dissect the evolution of these roles throughout key periods of Chinese societal transformation.The study centres on three pivotal epochs in contemporary China:the pre-liberation era(prior to 1949),the era of socialist construction(1949-1978),and the phase of economic reform(post-1978).Despite the undeniably persistent underpinning of traditional gender roles throughout history,this analysis offers insight into the essence of feminist movements-an ongoing struggle against the subjugation of women.While notable strides have been made in enhancing the status and rights of women in recent decades,it becomes evident that achieving genuine gender equality necessitates a more nuanced approach beyond the mere expansion of educational and occupational opportunities for women.True transformation mandates heightened awareness of gender inequality across all societal domains,catalysing collective participation in social initiatives by both genders.This article underscores the imperative of multifaceted engagement to drive meaningful and lasting shifts in gender dynamics.
文摘Karl Ludwig Kahlbaum(1828-1899)was the first to conceptualize and describe the main clinical features of a novel psychiatric illness,which he termed catatonia in his groundbreaking monograph published 150 years ago.Although Kahlbaum postulated catatonia as a separate disease entity characterized by psychomotor symptoms and a cyclical course,a close examination of his 26 cases reveals that most of them presented with motor symptom complexes or syndromes associated with various psychiatric and medical conditions.In his classification system,Kraepelin categorized catatonic motor symptoms that occur in combination with psychotic symptoms and typically have a poor prognosis within his dementia praecox(schizophrenia)disease entity.Because of the substantial influence of Kraepelin’s classification,catatonia was predominantly perceived as a component of schizophrenia for most of the 20th century.However,with the advent of the psychopharmacotherapy era starting from the early 1950s,interest in catatonia in both clinical practice and research subsided until the early 2000s.The past two decades have witnessed a resurgence of interest in catatonia.The Diagnostic and Statistical Manual of Mental Disorders Fifth Edition,marked a paradigmatic shift by acknowledging that catatonia can occur secondary to various psychiatric and medical conditions.The introduction of an independent diagnostic category termed“Catatonia Not Otherwise Specified”significantly stimulated research in this field.The authors briefly review the history and findings of recent catatonia research and highlight promising directions for future exploration.
