Abstract. High-quality research developed during the 19th century established the foundations of rock strain investigations. Careful observation and description of rock fabrics and deformed objects in rocks allowed early researchers to obtain mathematical expressions that are still used today to quantify strain. Thus, in a span of a few decades, and applying basic scientific methodology, these researchers developed the concept of the strain ellipsoid, defined mathematically the difference between constant-volume and volume-loss deformation, constructed the basic equations that define pure and simple shear deformation, and discovered the mechanism of pressure–solution deformation. These advances were fundamental to seminal works on strain analysis and deformation fabrics in the mid-20th century. However, they are rarely addressed in modern studies, which suggests a lack of awareness among current researchers. In order to bring attention to these landmarks of strain research, I provide a historical review of the high standards of analysis that led to the definition of the fundamental equations and concepts on strain during the 19th century.

Kasimir Malewitschs suprematistische Hauptwerke ›Schwarzes Quadrat‹, ›Schwarzer Kreis‹ und ›Schwarzes Kreuz‹ von 1915 setzen sich aus schwarzen Formen auf weißem Grund zusammen. Der Typus des Schwarzweißbildes weist überraschende Parallelen zu den bildlichen Wahrnehmungsinstrumenten auf, die vom ausgehenden 18. bis Anfang des 20. Jahrhunderts in den Experimenten der Farbenlehre, physiologischen Optik und Psychologie verwendet worden sind. Die vorliegende Studie untersucht diese Parallelen in drei Schritten: Zunächst erfolgt eine allgemeine Charakterisierung des Schwarzweißbildes mit Hilfe des Kontrastbegriffs von Edmund Husserl. Des weiteren wird die Entstehung und Funktion des schwarzweißen Kontrastbildes in den Wissenschaften des 19. Jahrhunderts typologisch herausgearbeitet. Unter Berücksichtigung des Wissensbegriffs von Max Scheler wird abschließend die Spezifik des Wissens eruiert, das die Schwarzweißbilder sowohl in der Malerei Malewitschs als auch in den genannten Wissenschaften generieren. Malevich’s main Suprematist works, such as ›Black Square‹, ›Black Circle‹, and ›Black Cross‹ from 1915, consist of black shapes on white ground. Surprisingly this series of shapes strongly resembles scientific black-and-white images used for research on colour theory, physiological optics, and psychology throughout the 19th century. This paper examines the parallels between Malevich’s paintings and the scientific drawings in three steps: It first characterizes black-and-white images in general, using Edmund Husserl’s definition of the term ›contrast‹. Secondly, the paper investigates the development and function of black-and-white images as tools of perception in the sciences. It finally discusses the specific knowledge generated through Malevich’s art and through scientific black-and-white images, following Max Scheler’s phenomenological identification of knowledge.

Abstract 1. The history of paroxysmal nocturnal hemoglobinuria is reviewed, and attention is called to four case reports published in the 19th century. A bibliography of the disease is appended. 2. The outstanding work of Paul Strübing is reviewed. Strübing identified paroxysmal nocturnal hemoglobinuria as a disease entity in 1882 but failed to give it a distinctive name. He described the disease with great accuracy, calling particular attention to the part played by sleep in precipitating the paroxysms. He cited earlier reports of nocturnal hemoglobinuria and by provocative tests differentiated the disease from the other paroxysmal hemoglobinurias. On the basis of his observations he proposed theories regarding the pathogenesis of the disease which have now been shown to be remarkably accurate.

During the 19th century new forms of government emerged, understanding themselves explicitly as nation-states. The new definition of the state had to include its members by defining them as citizens, a definition which included both equalizing and differentiating aspects. The education system fulfilled a key role in educating these future citizens. While the principal setting was not a national, I intend to show how this national logic shaped constructions of various types of nation-state citizens made through the public school based on empirical evidence from the Luxembourgian curriculum. In an exemplifying way, the motivation behind the respective changes and continuities will be uncovered concerning social differentiation in secondary education and a strong regional differentiation in the homebound lower branches of education.http://dx.doi.org/10.15572/ENCO2015.11

Difference is a social construction, and as such it needs a discourse to produce meaning and be socially effective. As a discourse is always socially and historically grounded, so it is the meaning of difference. This article proposes that the difference in the contemporary world is dominantly articulated in the discourse of diversity, as the discourse of exoticism was the dominant discourse of difference in the 19th Century. This proposal will be proved as I show that, as diversity becomes the appreciated discourse in the present, the exoticism loses its value. Stating that, I will try to understand the conditions of existence of each discourse. I will argue that the exoticism was founded in the 19th century upon three fundaments: imperialism, the idea of progress and nation. They provided the condition for a discourse that based the production of difference on the stable separation of an internal and an external space. After examining the fundaments and their relations with the discourse of exoticism, I will show that the production of difference is no longer based on stable notions of internal and external spaces. Currently, difference is produced on the basis of fragmented and globalized social relations, which requires a discourse flexible enough to cope with these material conditions. The discourse of diversity is this discourse.

Church vis it vis culture among the republican Afrikaner of the 19th century - an historical investigation. In this study attention is given to the question of the correlation between and/or position of the church vis a vis culture among the republican Afrikaner of the 19th century. Initially attention is given to  a workohle definition of church and culture and then, in the light of Calvinist theology, the relationship is discussed. Eventually the stated problem is discussed and the conclusion formulated that the culture of the Afrikaner was strongly influenced and directed by its theological viewpoints. A few conclusions are drawn.

The article is devoted to the phenomenon of an epic novel, a unique genre phenomenon that arose in Russian literature of the 19th century. While the West European novel lost its national breadth and depth, the Russian novel was able to maintain an epic dominance, revived many of the signs and characteristics of ancient epics based on the material of modern life. The basis for the revival of an epic novel based on Russian soil was: the nature of Russian realism, a special understanding by Russian writers of man and his role, as well as religious consciousness and collegiality. The author of the article discusses the meanings of the definition of “epic”, the concept of “epic”, shows the need for their rapprochement based on the disclosure of the features of the epic novel. The article analyzes the views of literary scholars of the 20th century, which came close to the need to highlight such a dominant form of the Russian novel of the second half of the 19th century, but due to ideological and political trends did not determine the most important foundations of the epic novel. The work outlines the need to study the totality of the artistic world of the epic novel, the special objectivity of Russian writers, which allowed them to come to global and universal problems. The phenomenon of the epic novel is largely due to the precedent picture of the world, the conscious choice of a character between personal, selfish and popular principles in favor of the latter.

AbstractField work in southwestern Idaho in 1959 has led to definition of a boundary zone between the Great Basin and Plateau culture areas. Around A.D. 1300, this boundary lay along the Snake River in southwestern Idaho, but in the 19th century it lay nearly 100 miles to the north of the Snake River. It is suggested that the contemporary environment of southwestern Idaho was established about 1000 B.C.

The article is devoted to the work of A. Bely in the development of Russian culture in the late 19th - early 20th centuries. Attention is paid to the motives of the creative path of the philosopher-poet, who created the basis of Russian symbolism. By analyzing the cultural and historical manifestations of the second half of the 19th century and the first half of the 20th century, reflection in the works of art and science workers, an assessment of the severity of symbolism for the development of Russian philosophy and the field of art in general. In the process of the formation of symbolism in Bely's work, neo-Kantian motives are clearly revealed in the formulation of the problem of the difference between subjective perception and the essence of the object of perception in itself, that is, distinguishing between the symbol and the signified. By comparing Bely's views with the concept of sophiology and anthroposophy, distinct Kantian positions of the philosopher-poet stand out. These include the schematism of space and time, an attempt to apply the categories of natural science to the field of philosophy of art, as well as the demarcation of the immanent and the transcendent. Despite the fact that the ideas of the philosopher-poet in their form have similar positions with the anthroposophy of R. Steiner and with the ideas of V. Solovyov, however, the key content is the neo-Kantian methodology of "critical deepening" of thought and its rationalization. The actualization of Bely's creativity and the issue of his neo-Kantian motives is carried out by attracting research from related branches of knowledge on the principles of interdisciplinary consideration and implementation of an integrated approach.

Pre-Columbian artefacts have been collected and exhibited in Europe since the 16th century. For a long time, they were considered exotic curiosities, ‘grotesque’ attempts at art by inferior peoples. This was a judgement stemming from a Eurocentric definition of art and, during the 19th century, indissociable from colonial and imperialist ideology. We present some views held in scholarly circles about pre-Columbian art in nineteenth-century France and focus on two artists, Jean Frédéric de Waldeck (1766-1875) and Emile Soldi (1846-1906), who drew from contemporary ethnographic and archaeological research, and pre-Columbian history to challenge the limits of academicism and the Beaux-Arts system.
