History dynamics of unified empire in China(770 BC to 476 BC)

The laws and regulations in human history can be revealed by computational models.From 221 before Christ(BC)to 1912 Anno Domini(AD),the unification pattern has dominated the main part of Chinese history for 2132 years.Before the emergence of the first unified empire,the Qin Empire in 221 BC,there existed the Eastern Zhou dynasty(770 BC to 221 BC).This long dynasty has two stages,and here we focus on the first stage.This Spring-Autumn stage was from 770 BC(with 148 states)to 476 BC(with 32 states).The whole country(China)is modelled as a multi‐agent system,which contains multiple local states.They behave autonomously under certain action rules(wars and conflicts),which forms the main reason for the annexations and disappearance of most states.Key factors(power,loyalty,bellicosity and alliance)have been considered in our model settings,and simulation outcomes will be monitored and collected.Eventually,an optimal solution is obtained,which well unveils the internal mechanism and statistical features of real big history.Furthermore,counterfactuals are used to explore the non‐linear effects of the key factors,which deepens the authors’understanding of civilisa-tion evolutions in human history.

From Regional to Intercontinental Trade： The Successive European Trade Empires From the 16th to the 18thCentury in Asia

For a very long time, the areas available for continuous long-distance trade were limited to territories of Braudel＇s Mediterrande （1949）. Whatever the commercial organizations （merchants in the Roman or the Fatimid Empires, the Hanseatic League, the Florentine Companies） were, their trade was not able to directly handle branches more than a month＇s sailing from their main base （in the best conditions）. During the three centuries after Vasco de Gama had reached India, European trading areas dramatically expanded to the shores of Asia, and a long period of harsh competition set the East India Companies of the main European powers of the time against one another. What were the elements that allowed these companies to maintain transactions over such vast areas？ And why were some of these companies far more successful than the others？ A large set of secondary sources focusing on one company or on a particular aspect of trade （Chauduri, 1978; Israel, 1989; Subrahmanyan, 1993; Ames, 1996） exist, however, none of them treat their successive successes and failures. The aim of this paper is to briefly review these sources, to extract information from them and to compare the economic adaptations and innovations that allowed these companies to be the greatest of their time.

THE ROLE OF UMBRELLA AGREEMENTS IN ACHIEVING SUSTAINABILITY GOALS:ENERGY EFFICIENCY AT THE EMPIRE STATE BUILDING

In this paper we investigate whether innovative and flexible contractual arrange-ments can support the process of achieving ambitious sustainability goals.We explore this question through an analysis of the role of umbrella agreements in driving energy savings in the building sector.Drawing on a case study of the iconic Empire State building,we examine the typical challenges faced by clients and con-tractors in devising suitable agreements that facilitate managing contractual and performance risks,as well as the sharing of responsibilities and cooperation between multiple project stakeholders.We find that the project arrangements appear to exhibit the adoption of the key characteristics commonly found in umbrella agree-ments which incorporate sustainability measures that maximize income through efficient delivery of outcomes.Specifically,this means that they need to enable stakeholders to manage repeated review cycles,complex perceptions and expecta-tions,and different tacit assumptions and codes of behaviour,as well as managing and communicating in networks and obtaining agreement also from non-contrac-tual parties.Moreover,we demonstrate that umbrella agreements can facilitate a network perspective of business relationships by emphasizing value co-creation and the embeddedness of firms within a network of interactions.

Simulating rise and fall cycles of Vietnam empires

The life cycle pattern of empires is pervasive worldwide,and this is caused by multiple factors.In the history of Vietnam,there are totally about ten empires or dynasties,which have aggregately lasted for more than one thousand years.Here,we apply the life cycle model and agent-based modeling to uncover the underlying mechanisms of the life cycle pattern for Vietnam empires.Macroscopically,the man-land relationship greatly shapes the life cycle pattern of traditional agricultural empires.The balancing process between land and population is critical for the empires.The relationship between incomes and costs has determined the actions or strategies of the social members or individuals.It suggests that our optimal solutions and simulations have perfectly matched the real history of Vietnam.Under three optimal solutions,the distributions of simulated and real empire durations in history can be well-matched,in terms of both discrete(histogram)and continuous forms(kernel density).It indicates that the history of human society is a dynamic process,which is determined by certain evolutionary rules and regulations.Therefore,we are able to back-calculate,simulate,and even predict the future of empires or countries.

Modernization of Medicine in the Ottoman Empire and Its Effects on Forensic Sciences

Modernization in medicine began in the Ottoman Empire in the 19^(th)century.Until that time,medical education had been provided through the traditional master-apprentice practices and its methods had relied on custom or religion.The most important of these reforms was in 1827,when the first medical schools in surgical and clinical branches were opened in Istanbul.The lack of contemporary understanding in medical education until that time had caused an underdevelopment in forensic sciences as it had in various other fields.Following the reform movements,the contents of the forensic medicine curriculum,mainly influenced by the French medical schooling,touched upon all areas of forensic sciences such as pathology,toxicology,organic chemistry,neuropsychiatry,gynecology,handwriting analysis and criminalistics.It was noteworthy to see such rapid development in scientific modernization considering the fact that,before the reform movements,the religion had a repressive effect and it was forbidden to even perform laboratory tests or examinations on corpses.In the modem Turkish Republic,founded in 1923 after World War I,scientific reforms gained momentum and began competing with the modem world.Such that,after a letter sent to the Turkish Government by Albert Einstein in 1933,the contemporary Turkish universities embraced the scientists who escaped from the Nazi regime.

Introduction:Empire and Information in Late Imperial Chinese History

Commerce and Empire in the Borderlands： How do Merchants and Trade Fit into Qing Frontier History？

As our understanding of the Qing empire and its various borderlands has evolved, so too have we come to appreciate China＇s early modem commercial sophistication. In recent North American studies of the Qing, the links between commerce and conquest have come under investigation, and we are increasingly urged to pay attention to merchants and merchant capital. But how should we understand the relationship between merchants and the Qing empire in the borderlands？ This article surveys selected work on the borderlands and commercialization, primarily in the Northwest and Southwest. The goal is to initiate a more comprehensive discussion of how to understand the intersection of commerce and empire while also making some suggestions for ways that borderlands history might shape future work on China.

Nationalist Thoughts and Islam in the Late Ottoman Empire

Early modernization reform from the 19th century to the early 20th century led to the secularization of the Ottoman Empire in respect to politics,law,and education.Competition between contradicting secular and Islamic thoughts has occurred since then,and it has produced the divisions of pan-Islamism,Modernism,and Turkism in the ideological field of the Ottoman Empire.Such phenomenon is the manifestation of political and ideological chaos of the late Ottoman Empire,which has intertwined with the contradiction of tradition and modernity,between the Orient and the West,presenting the developing trends of diversification,complexity,and variability.Intensified ideological struggle occurred in the late Ottoman Empire previous to its collapse.Social and political reforms began to transform the country from a traditional empire to modern nation-state.Due to the relationship between trends of political thoughts and Islam,nationalism could not get rid of the impact of Islam in the late Ottoman Empire.Islam has not only perpetuated pan-Ottomanism and pan-Turkism in the form of pan-Islamism,it has also exerted a wide range of effects as a relative individual trend of political and social thoughts.
