КОНСТИТУЦИЯ ИРАКА 2005 ГОДА И ПРИНЦИПЫ ИСЛАМА*
The article analyses constitutional provisions of the Republic of Iraq (2005) referring to Shari‘a and Islam in general. It offers a comparative analysis of the present Constitution and the previous one (1970). It is demonstrated that there are virtually no significant places for Shari‘a and Islam in the Constitution of 1970. The Constitution of 2005 offers a more meaningful role for the Islamic principles. It is also demonstrated that still the new Constitution of Iraq has very limited mentions of Islam which can be connected with the pressure of the provisional American occupation authorities, as well as Shi‘a — Sunni contradictions. The Administration of the Coalition Provisional Authority of Iraq produced a tough resistance to the attempts to include Islamic principles in any project of future Constitution. As a result, the final version of the constitution was neither Sunni nor Shi‘a. Against this background, the very fact of a reduced number of references to Islam (without Shia or Sunni connotations) might have been regarded as a sort of compromise. Meanwhile, it can be concluded that throughout the extremely complicated political history of the country the consensus in constitutional construction has not been obtained so far.Статья посвящена исследованию норм Конституции Республики Ирак 2005 года, касающихся шариата и ислама в целом. Проводится сравнительный анализ действующей Конституции республики с предыдущей Конституцией 1970 года. Показано, что в Конституции 1970 года шариату и исламу практически не было отведено существенного места, в то время как Конституция 2005 года отводит принципам ислама более заметную роль
Rise of the War Machines: Charting the Evolution of Military Technologies from the Neolithic to the Industrial Revolution
What have been the causes and consequences of technological evolution in world history? In particular, what propels innovation and diffusion of military technologies, details of which are comparatively well preserved and which are often seen as drivers of broad socio-cultural processes? Here we analyze the evolution of key military technologies in a sample of pre-industrial societies world-wide covering almost 10,000 years of history using Seshat: Global History Databank. We empirically test previously speculative theories that proposed world population size, connectivity between geographical areas of innovation and adoption, and critical enabling technological advances, such as iron metallurgy and horse riding, as central drivers of military technological evolution. We find that all of these factors are strong predictors of change in military technology, whereas state-level factors such as polity population, territorial size, or governance sophistication play no major role. We discuss how our approach can be extended to explore technological change more generally, and how our results carry important ramifications for understanding major drivers of evolution of social complexity. © 2021 Turchin et al.

Quantitative historical analysis uncovers a single dimension of complexity that structures global variation in human social organization
Do human societies from around the world exhibit similarities in the way that they are structured, and show commonalities in the ways that they have evolved? These are long-standing questions that have proven difficult to answer. To test between competing hypotheses, we constructed a massive repository of historical and archaeological information known as "Seshat: Global History Databank." We systematically coded data on 414 societies from 30 regions around the world spanning the last 10,000 years. We were able to capture information on 51 variables reflecting nine characteristics of human societies, such as social scale, economy, features of governance, and information systems. Our analyses revealed that these different characteristics show strong relationships with each other and that a single principal component captures around three-quarters of the observed variation. Furthermore, we found that different characteristics of social complexity are highly predictable across different world regions. These results suggest that key aspects of social organization are functionally related and do indeed coevolve in predictable ways. Our findings highlight the power of the sciences and humanities working together to rigorously test hypotheses about general rules that may have shaped human history

E2F1 Regulates Cellular Growth by mTORC1 Signaling
During cell proliferation, growth must occur to maintain homeostatic cell size. Here we show that E2F1 is capable of inducing growth by regulating mTORC1 activity. The activation of cell growth and mTORC1 by E2F1 is dependent on both E2F1's ability to bind DNA and to regulate gene transcription, demonstrating that a gene induction expression program is required in this process. Unlike E2F1, E2F3 is unable to activate mTORC1, suggesting that growth activity could be restricted to individual E2F members. The effect of E2F1 on the activation of mTORC1 does not depend on Akt. Furthermore, over-expression of TSC2 does not interfere with the effect of E2F1, indicating that the E2F1-induced signal pathway can compensate for the inhibitory effect of TSC2 on Rheb. Immunolocalization studies demonstrate that E2F1 induces the translocation of mTORC1 to the late endosome vesicles, in a mechanism dependent of leucine. E2F1 and leucine, or insulin, together affect the activation of S6K stronger than alone suggesting that they are complementary in activating the signal pathway. From these studies, E2F1 emerges as a key protein that integrates cell division and growth, both of which are essential for cell proliferation
The La Marca model revisited: Structuralist goodwin cycles with evolutionary supply side and balance of payments constraints
This research is aimed at investigating the causes of volatility that affect middle‐income countries by studying the La Marca model. Drawing from the open‐economy Goodwin tradition, this model demonstrates that economic activity, income distribution and accumulation of foreign assets dynamically interact, resulting in a pattern of dampened cycles. The study consists in analyzing the characteristics of the model by initially imposing: (I) a constant real exchange rate; (II) a constant net external asset to capital ratio, which is in line with the balance of payments dominance theory and (III) a fixed income distribution. We then (IV) expand the original model by adding an evolutionary supply‐side in which productivity is at the center of the economic dynamic through international technology transfer and the Kaldor‐Verdoorn effect. The results show that (1) the model always converges. (2) The restrictions (I) and (II) remove the cyclical component of the model, which highlights a central difference between La Marca and the original Goodwin model. (3) Fixed income distribution leads to a monotonic trajectory that reduces oscillations. (4) The inclusion of productivity dynamics generates new sources of volatility in the relationship between productivity, capacity utilization and net external assets and is in line with the structuralist argument of structural fragility

An Introduction to Seshat: Global History Databank
This article introduces the Seshat: Global History Databank, its potential, and its methodology. Seshat is a databank containing vast amounts of quantitative data buttressed by qualitative nuance for a large sample of historical and archaeological polities. Thee sample is global in scope and covers the period from the Neolithic Revolution to the Industrial Revolution. Seshat allows scholars to capture dynamic processes and to test theories about the co-evolution (or not) of social scale and complexity, agriculture, warfare, religion, and any number of such Big Questions. Seshat is rapidly becoming a massive resource for innovative cross-cultural and cross-disciplinary research. Seshat is part of a growing trend to use comparative historical data on a large scale and contributes as such to a growing consilience between the humanities and social sciences. Seshat is underpinned by a robust and transparent workflow to ensure the ever growing dataset is of high quality
