This paper presents the results of an investigation of the variability in macro-circulation forms at the mid-tropospheric level distinguished in the Vangengeim-Girs (V-G) classification. The annual frequencies of circulation forms in the years 1891–2010 proved significant fluctuations, which provided the basis for distinguishing 7 circulation epochs. The epochs illustrate secular changes in the character of dominant forms – zonal circulation (W) prevailed at the turn of the 20th century; meridional forms E and C developed next, and zonal circulation began to dominate again after 1990.

Since the late 20th century major, European cities have exhibited large projects driven by neoliberal urban planning policies whose aim is to enhance their position on the global market. By locating these projects in central city areas, they also heighten and reinforce their privileged situation within the city as a whole, thus contributing to deepening the centre–periphery rift. The starting point for this study is the significance and scope of large projects in metropolitan cities’ urban planning agendas since the final decade of the 20th century. The aim of this article is to demonstrate the correlation between the various opposing conservative and progressive urban policies, and the projects put forward, for the city of Madrid. A study of documentary sources and the strategies deployed by public and private agents are interpreted in the light of a process during which the city has had a succession of alternating governments defending opposing urban development models. This analysis allows us to conclude that the predominant large-scale projects proposed under conservative policies have contributed to deepening the centre–periphery rift appreciated in the city.

The article analyzes views on innovation in the literary science of the early twentieth century and the work of Alash representatives in an era that is a period filled with profound changes and large-scale innovations in Kazakh society. In addition, works related to freedom, enlightenment, politics, spiritual values, the position of the people as a whole and social changes are considered the idea of independence and continuity. On the way of evolutionary development of the Kazakh literature, artistic power, thematic and ideological character, substantial and stylistic features of poetry of poets in the beginning of the XX century and during the Great Patriotic War, in subsequent years and years of independence are discussed in detail. In addition, on the basis of literary traditions and novelty, the works of prominent poets of Kazakh poetry of the 20th century and Independence are considered and comprehensively characterized, i.e. internal motives, the content of life phenomena in national poetry are analyzed in close connection with the works of poets. The original vision of the traditional and differentiated in the literature of the Soviet period in the works of poets from a new perspective, from the point of view of today. In addition, the works of outstanding poets of Kazakh poetry in the period of the 20th century and independence are considered on the basis of classical tradition and novelty in literature.

The author of the article considers the development of Montenegrin law in the 19th - early 20th centuries and tries to assess the results of the legislative activities of the Montenegrin authorities, that issued new regulations and carried out large-scale codification work on regular basis. From the point of view of the normative approach, widely used in legal science, these activities seemed quite successful; the laws that met urgent needs of the state's development were created within short periods of time. However according to the sociological approach, one has to admit that the significant part of Montenegrin legislation was just a formality and was hardly implemented in practice.


Tapestry, the most costly and coveted art form in Renaissance and Baroque Europe, has long fascinated scholars. In the 19th and early 20th centuries, researchers delved into archival sources and studied extant tapestries to produce sweeping introductions to the medium. The study of tapestry, however, fell outside mainstream art history, with tapestry too often seen as a less important “decorative art” rather than a “fine art.” , Also, tapestry did not fit easily into an art history that prioritized one master, as the making of a set of large-scale tapestries required a team of collaborators, including the designer, cartoon painters, and weavers, as well as a producer/entrepreneur and, often, a patron. Scholarship on European tapestries in the Early Modern period, nevertheless, flourished. By the late 20th century art historians turned attention to the “decorative arts” and tapestry specialists produced exciting new research illuminating aspects of design, production, and patronage, as well as tapestry’s crucial role in the larger narrative of art and cultural history. In 2002, the Metropolitan Museum of Art’s landmark exhibition and catalogue, Tapestry in the Renaissance: Art and Magnificence, spotlighted the art form, introduced it to a broad audience, and brought new understanding of tapestry as art. A sequel, the Met’s 2007 exhibition and catalogue, Tapestry in the Baroque: Threads of Splendor, followed. Other major museums presented ambitious exhibitions, accompanied by catalogues with substantial new research. In addition, from the late 20th century, institutions have produced complete catalogues of their extraordinary European tapestry holdings, among them: the Metropolitan Museum of Art in New York; the Patrimonio Nacional in Spain; the Rijksmuseum in Amsterdam; the Art Institute of Chicago; and the Burrell Collection in Glasgow. At the same time, articles and books exploring specific designs, designers, producers, and patrons appeared, with some monographs published in the dedicated series, Studies in Western Tapestry, edited by leading scholars Guy Delmarcel and Koenraad Brosens, and produced by Brepols. Tapestry research has often focused on the works of well-known designers and their exceptionally innovative work, such as the artists Raphael (b. 1483–d. 1520) or Peter Paul Rubens (b. 1577–d. 1640). High-quality production at major centers, including Brussels or at the Gobelins Manufactory in France, has also captured scholars’ attention, as have important patrons, among them Henry VIII of England (b. 1491–d. 1547) or Louis XIV of France (b. 1638–d. 1715). Newer directions for research include the contributions of women as weavers and entrepreneurs, the practice of reweaving designs, and the international reach and appeal of Renaissance and Baroque tapestry beyond Europe.

AbstractThe evolution of biogeochemistry, retraces the important historical steps in part, covered by Gorham (Biogeochemistry 13:199–239, 1991) in the 18–19th centuries—with new emergent linkages and trends in 20–21st centuries. In the post-phlogiston period, key synthetic connections are made between weathering, atmospheric chemistry, carbon cycling, and climate change. Early work in the 19th century, focused on weathering and the importance of organisms in the exchange of carbon dioxide between the rocks and the atmosphere, provided foundations for new analytical approaches. The role microbes in connecting abiotic and biotic processes begins to emerge, based largely on the existing knowledge of stoichiometry in agricultural soils and plants. This in part, leads to the founding of ecology and its linkages with evolution and biogeography. Verandsky boldly emerges in the 20th century, with his concepts of a biosphere and a noosphere, as concerns begin to arise about human impacts on nature. The development of organic geochemistry as a discipline, allowed for new roots to develop in the evolution of biogeochemistry through linkages between short and long-term carbon cycles. In the 20th century, a new interesting stoichiometry emerges in biogeochemistry—as related to the Green Revolution, human population growth, and eutrophication problems. The advent of long-term and large-scale experiments help to constrain the complexity of non-linearity and regional differences in fluxes and rates in biogeochemical work. A new age begins in the 21st century whereby molecular approaches (e.g. omics) combined with large-scale satellite, monitoring, survey, observatory approaches are combined in the development of Earth System models. These new connections with ecological/evolutionary genetics are one of the more dramatic and important aspects of biogeochemistry in modern times.

If the history of the Middle East in the 20th century is a history of fundamental social changes and dislocations, then surely one important part of that story is the transformation that took place in the agrarian sector of many Middle Eastern societies. The politics of landownership and the projects of land reform in the 20th century were indeed among the most ambitious of the statist projects undertaken during what we can now look back on as the “age of modernization.” Like so many large-scale projects of social engineering, land reform in the Middle East captured the optimism and idealism of modernization while producing some of its most brutal and unforeseen consequences.

Analytic philosophy, with its emphasis on clear, topic-based argument, is usually dated to the early 20th century and is contrasted with Continental philosophy, which is more often concerned with overarching systems and theories. Analytic philosophers did not turn their attention to music until the last decades of the 20th century. Of course, they were influenced by and commented on earlier, philosophically motivated discussions of music, starting with the Greeks and much later including relevant work by musicologists, composers, critics, and psychologists as well as philosophers. Three topics became prominent: the expression of emotion in music, the nature of musical works, and what is involved in understanding and appreciating music. Philosophers asked if music expresses emotion, and if they answered yes, as most did, they asked how this is possible and whether the attribution could be literal. Is music expressive by virtue of some connection with the world of human feeling or in its own, perhaps indescribable fashion? Why is the listener moved by the music’s expressiveness if no one undergoes the emotions it expresses? In the case of works, the interest was in their connection to notational specifications and performances. If they are abstract, does this mean they are discovered rather than created? Philosophers considered what makes a performance a performance of a given work, whether faithfulness to the work is important and what it entails, and in what respects the performer is free to interpret the work. In addition, they debated the prerequisites for musical understanding: for example, is knowledge of musical technicalities helpful or even necessary, and should the listener track the music’s large-scale structure? And why do we value music so highly given that it does not provide useful information? As these topics imply, the primary focus at first fell on notated classical Western music composed for multiple, live performances by instrumentalists, and the main perspective was that of the listener. When the scope of interest was broadened, different issues emerged. Jazz, for example, raised questions about the nature of improvisation and about how the appreciation of music not intended for replay might differ from that appropriate for notated works. Rock, with its reliance on electronic mediation and recordings, provoked new debate about the nature of recorded works and about the relevant differences between recordings of works intended for live performance and recordings of works that essentially involve electronic manipulations and the kind of editing that cannot be achieved in real time. The range of philosophical topics invited by consideration of music and its role in human life continues to expand, though this article concentrates on those matters that have received most attention.

Mining has been a major contributor to economic development in Australia since British arrival in the late 1700s, with little to no thought regarding the long-term environmental consequences. This study assesses the metal pollution legacy caused by different smelting methods and mining activities during the British colonialism in western Tasmania. This region was the largest copper producer in the Southern Hemisphere during the 20th century. Lake sediments from Basin Lake and Owen Tarn, 12 and 5 km from Queenstown’s mines, respectively, were used to reconstruct historical metal contamination. Temporal changes in metal concentrations (iron, copper, arsenic, selenium and lead) were assessed in relation to the scale of mining activities and the technologies used. Sedimentation rates and metal influxes increased from 1900, reflecting the beginning of copper mining in Mount Lyell. Observed metal concentrations peaked after 1930, coinciding with the introduction of large-scale open-cut operations and an expansion of the mining machinery used. All elements underwent at least minor enrichment (EF 1-3) during the lifespan of the mine, with lead and copper undergoing extremely severe enrichment (EF > 50). Although smelters contributed to metal increases in the lakes, large open-cut large operations in the 1930s contributed most to metal contamination. Local metal deposition from mining-related activities decreased significantly once operations decreased, with selenium and arsenic decreasing nearly to background levels within 50 years. Lead and copper, the elements which underwent major enrichment, have not yet reached background values. The ecological consequences include the current degraded local landscape, poor water quality and disrupted local biota. Knowledge about the environmental impacts of mining in western Tasmania is less known compared to other sites around the world with a similar history. Our results demonstrate the urgent need to develop better policies and remediation programs that can mitigate the consequences of metal pollution from abandoned mines in Australia.

The scenario of an expanding universe envisioned in the early part of the 20th century has been replaced by one where we live in a chaotic, eternally bubbling universe. Every bubble has the potential for developing into a new habitable universe. In this essay I describe how large-scale quantum effects could be driving the chaotic bubbling universe.
