Early States and Power in the Baltic Sea Region (8th–11th Centuries): A Comparative Study

The aim of the article is to trace the emergence and the development of the early states of the Scandinavians, the Polabian and the Pomeranian Slavs and to investigate their main power centers. The author relies on previous research, uses theoretical achievements of historical anthropology and combines them with comparative methodology to study both archaeological and written sources. This approach allows to establish distinct political typologies in the region, namely various types of chiefdoms and principalities. The paper illuminates similar and mostly simultaneous trajectories of the evolution of those polities, emphasizes the role of central places in the respective political systems and in the governing mechanisms. During the late 8th – the early 11th centuries there had existed complex chiefdoms and chiefdom confederacies, which slowly declined towards the end of the period.

Isotopic investigation of skeletal remains at the Imdang tombs reveals high consumption of game birds and social stratification in ancient Korea

Understanding the development of early states on the Korean Peninsula is an important topic in Korean archaeology. However, it is not clear how social structure was organized by these early states and what natural resources were utilized from their surrounding environments. To investigate dietary adaptation and social status in ancient Korea, stable isotope ratios and radiocarbon dates were measured from humans and animals from the Imdang cemetery, Gyeongsan city, South Korea. The results indicate that the Imdang diet was mainly based on C3 plants and terrestrial animals. Animal remains in the graves were directly consumed as daily food items as well as for ritual offerings. MixSIAR modeling results revealed that the dietary sources for the humans were: game birds > C3 plants > terrestrial herbivores > marine fish > C4 plants. The finding that the game birds represented the highest contribution to the whole diet, indicates that game birds must have been intensively hunted. Furthermore, elites consumed more game birds than their retainers and they also consumed seafood as a privileged dietary item in the Imdang society. This study demonstrates that the Apdok was a stratified society having high variations in the consumption of food items available to an individual and provides new insights about the subsistence and social status of the early ancient Apdok state on the Korean Peninsula.

Changing social inequality from first farmers to early states in Southeast Asia

When the first rice farmers expanded into Southeast Asia from the north about 4,000 y ago, they interacted with hunter-gatherer communities with an ancestry in the region of at least 50 millennia. Rigorously dated prehistoric sites in the upper Mun Valley of Northeast Thailand have revealed a 12-phase sequence beginning with the first farmers followed by the adoption of bronze and then iron metallurgy leading on to the rise of early states. On the basis of the burial rituals involving interment with a wide range of mortuary offerings and associated practices, we identify, by computing the values of the Gini coefficient, at least two periods of intensified social inequality. The first occurred during the initial Bronze Age that, we suggest, reflected restricted elite ownership of exotic valuables within an exchange choke point. The second occurred during the later Iron Age when increased aridity stimulated an agricultural revolution that rapidly led to the first state societies in mainland Southeast Asia.

Law Philosophical Foundations of the Early Eastern States

The article is devoted to the elucidation of the ideological foundations of the law of the states of the early civilizations of the East, which last from the VII millennium BC (Sumer and Akkad, Babylon, India, China and Egypt). The spontaneously formed mythical, religious, moral and rational components of the worldview, as well as elements of philosophical doctrines are analyzed, traced as the unity of the notions of the gravity of sin and sinful behavior and even the community as a whole, caste character based on the idea of the inevitability of social inequality, the subordinate position of women, and significant differences in different legal systems, based on the specifics of economic structure and political system, civilizational and cultural differences, historical features of state formation, as well as worldviews of peoples, their understanding of the world, world order, natural and terrestrial laws. It is concluded that the general primary basis of the legal worldview of the peoples of the early states of the East are mythical and religious beliefs of peoples (as, incidentally, in all other early states), which served to explain the world order and justify the general laws of nature, and also served as a criterion for evaluating human actions.These ideas were based on common to all civilizations moral ideas about good and evil, justice and injustice, truth and injustice, moral and immoral. In philosophical treatises, in some literary and legal sources of the ancient East, one can find key common moral postulates that take long from the most ancient beliefs and religions and moral rules, known to science, and then reflected in Hinduism, Christianity, Islam. From the point of view of social and state ideology, the ruling elite was interested in spreading and affirming the notions of the sanctity and inviolability of the supreme power of rulers, who often combined religious and secular power. The laws of the rulers were also proclaimed by the commands of the gods, the highe rpowers, which must be strictly observed by all. This view of laws was reinforced by a system of severe punishments for violating them. Although this together helped to centralize the early states, to establish more effective protection against external enemies, and from the point of view of internal organization to keep the people firmly in subjection, it did not contribute to the development of ideals of individual freedom.

Pump-probe X-ray holographic imaging of laser-induced cavitation bubbles with femtosecond FEL pulses

Cavitation bubbles can be seeded from a plasma following optical breakdown, by focusing an intense laser in water. The fast dynamics are associated with extreme states of gas and liquid, especially in the nascent state. This offers a unique setting to probe water and water vapor far-from equilibrium. However, current optical techniques cannot quantify these early states due to contrast and resolution limitations. X-ray holography with single X-ray free-electron laser pulses has now enabled a quasi-instantaneous high resolution structural probe with contrast proportional to the electron density of the object. In this work, we demonstrate cone-beam holographic flash imaging of laser-induced cavitation bubbles in water with nanofocused X-ray free-electron laser pulses. We quantify the spatial and temporal pressure distribution of the shockwave surrounding the expanding cavitation bubble at time delays shortly after seeding and compare the results to numerical simulations.

Dams, moats, and cities: climate and societies in late-Holocene China

Whilst the late-Holocene climate was becoming drier with an increasing number of climatic anomalies, with notably more frequent fluctuations in summer rainfall on an annual or decadal scale, many walled sites or cities emerged and became regional centres that witnessed population agglomeration and technological flowering. To feed their growing populations and their increasing demands on land, water, food, and other resources, these �cities� were drawn closer physically to riverine environments and wetlands. By diversifying and intensifying their subsistence strategies, and constructing infrastructure on a colossal scale, these late-Holocene walled towns or cities also fundamentally transformed their local landscapes. Examining key sites from the Huai river and the Yangtze Delta, this paper will compare the dynamic interactions between society, landscape, and the environment under different socio-economic conditions across different regions of late-Holocene China and investigate how these factors influenced and led to the emergence of complex societies or early states.

Medieval Legal Realism

This is a Research Note about the ongoing Project on the semantics of pactism (pactisme) in Catalan ancient law. Pactism is the name of the legal doctrine that grounds the validity of legal provisions upon a pact-based model. It was developed as a basis for Catalan Public law in the 13th, 14th and 15th centuries. We present it as a medieval realism. Looking at the concomitances of 20th century legal realism and the doctrine of pactism can shed light on the emergence of early states and the construction of legal doctrines stemming from the reception of Roman law, the wide use of ius commune, and the development of case-based law and Scholastic reasoning methods. The semantics of pact-modelling processes and outcomes has yet to be established. Thus, it is also contended that Digital Humanities can offer some technological solutions to unravel underlying linguistic, cognitive and ontological patterns to understand the political culture that came out of it and developed until the 18th c. in Catalonia.

Investigating the Effectiveness of Breast Cancer Supplemental Screening Considering Radiologists’ Bias

Breast density is known to increase breast cancer risk and decrease mammography screening sensitivity. Breast density notification laws (enacted in 38 states as of September 2020), require physicians to inform women with high breast density of these potential risks. The laws usually require healthcare providers to notify patients of the possibility of using more sensitive supplemental screening tests (e.g., ultrasound). Since the enactment of the laws, there have been controversial debates over i) their implementations due to the potential radiologists bias in breast density classification of mammogram images and ii) the necessity of supplemental screenings for all patients with high breast density. In this study, we formulate a finite-horizon, discrete-time partially observable Markov chain (POMC) to investigate the effectiveness of supplemental screening and the impact of radiologists’ bias on patients’ outcomes. We consider the conditional probability of eventually detecting breast cancer in early states given that the patient develops breast cancer in her lifetime as the primary and the expected number of supplemental tests as the secondary patient’s outcome. Our results indicate that referring patients to a supplemental test solely based on their breast density may not necessarily improve their health outcomes and other risk factors need to be considered when making such referrals. Additionally, average-skilled radiologists’ performances are shown to be comparable with the performance of a perfect radiologist (i.e., 100% accuracy in breast density classification). However, a significant bias in breast density classification (i.e., consistent upgrading or downgrading of breast density classes) can negatively impact a patient’s health outcomes.
