The subject of paper is the mathematical modeling of the spatial distribution of the medieval rural population. On the basis of the variational approach, two models of the hierarchy of centers are being developed, allowing with a high degree of reliability to identify the factors of the development of the settlement structure and to describe quantitatively the relationship between its most important parameters, such as density, population size and area.

This article approaches the study of the private library of the Murcian land surveyor Francisco Falcón de los Reyes, from the first half of the eighteenth century, which constitutes a clear example of the relationship between education and written culture. From the data extracted from a postmortem inventory and the subsequent appraisal and partition of goods among the heirs, we carried out a quantitative and qualitative analysis of said library. First, the text provides a biographical profile of this geometer, a descendant of slaves (new Christians), and describes the formative precariousness of these professionals in their time. The quantitative analysis of the bibliographic collection and its comparison with other private collections from similar socioeconomic fields indicate the importance of this particular collection. The qualitative study of authors and titles shows, on one hand, the high degree of mathematical training of the subject, who is shown to be a recipient of the fundamentally Valencian pre-illustrated reformist scientific mainstream, and, on the other hand, the purpose with which those books were incorporated into the funds of the collection. Together with the library, which we could call professional, due to its scientific nature, the inventoried religious matter in the form of printed documents makes up another interesting part of the collection, one of a catechetical nature in its various formative levels

In the last decades, sustainability has become the subject of many discussions mainly driven by the global concern over climate change and scarcity of natural resources. So, some measures were agreed in the major international rounds on the environment as well as on educationally planning of countries that have established a commitment to integrate sustainability in different educational levels. Hence, the objective of this study was to determine the importance given be by the veterinary medicine students about sustainability in their training. The study is descriptive with quantitative approach where the Likert scale questionnaire with 5 scales was used and applied to students of the last semesters of veterinary medicine in a university. Subsequently the data were tabulated and a general boxplot type graph was elaborated showing the distribution of data. Most students presented a high degree of agreement regarding the relationship between sustainability with professional training. It can be drawn the conclusion that it is important and necessary for the formation of the veterinarian of the future.

Niche construction is a process through which organisms alter their environments and, in doing so, influence or change the selective pressures to which they are subject. ‘Cultural niche construction’ refers specifically to the effect of cultural traits on the selective environments of other biological or cultural traits and may be especially important in human evolution. In addition, the relationship between population size and cultural accumulation has been the subject of extensive debate, in part because anthropological studies have demonstrated a significant association between population size and toolkit complexity in only a subset of studied cultures. Here, we review the role of cultural innovation in constructing human evolutionary niches and introduce a new model to describe the accumulation of human cultural traits that incorporates the effects of cultural niche construction. We consider the results of this model in light of available data on human toolkit sizes across populations to help elucidate the important differences between food-gathering societies and food-producing societies, in which niche construction may be a more potent force. These results support the idea that a population's relationship with its environment, represented here by cultural niche construction, should be considered alongside population size in studies of cultural complexity. This article is part of the themed issue ‘Process and pattern in innovations from cells to societies’.

The article considers the nominative field of the concept "court" in the history of the Russian official language on the material of legislative documents of the 18 th century. The subject of the study is the relationship between the official segment of the concept "court" and the ordinary segment in the context of ethnic mentality. The hypothesis of ethno-cultural neutrality of the official segment has been tested. Special attention is paid to the evaluation nominations of the concept, their syncretsemia is revealed. The activity of non-terminological, morally and religiously marked nominations in relation to terms is found. Functional-semantic insufficiency of legal categories, their stable connection with moral and ethical categories in legal language consciousness is shown. Domination of semantic and conceptual constituents "truthful", "righteous / decent", "fair" over "legal" is established. The functional weakness of the conceptual sphere "law" is noted. The traditional ethno-specific perception of legal language consciousness is stated as predominance of moral and ethical concepts "truth", "righteousness", "fairness", "good", "conscience", "soul" over the "law". A high degree of ethno-cultural marking of the official segment of the concept "court" with a dominant meliorative valuation was noted. The analysis of the ordinary segment of the concept "court" in Russian paremiology revealed the above mentioned ethno-cultural concepts with a prevailing pejorative estimate. The coincidence of the justice pattern in the official and ordinary legal consciousness is noted.

The Mesozoic-Cenozoic coral Order Scleractinia has been suggested to have originated or evolved (1) by direct descent from the Paleozoic Order Rugosa or (2) by the development of a skeleton in members of one of the anemone groups that probably have existed throughout Phanerozoic time. In spite of much work on the subject, advocates of the direct descent hypothesis have failed to find convincing evidence of this relationship. Critical points are:(1) Rugosan septal insertion is serial; Scleractinian insertion is cyclic; no intermediate stages have been demonstrated. Apparent intermediates are Scleractinia having bilateral cyclic insertion or teratological Rugosa.(2) There is convincing evidence that the skeletons of many Rugosa were calcitic and none are known to be or to have been aragonitic. In contrast, the skeletons of all living Scleractinia are aragonitic and there is evidence that fossil Scleractinia were aragonitic also. The mineralogic difference is almost certainly due to intrinsic biologic factors.(3) No early Triassic corals of either group are known. This fact is not compelling (by itself) but is important in connection with points 1 and 2, because, given direct descent, both changes took place during this only stage in the history of the two groups in which there are no known corals.

Queen Margaret (1070–93) has been the subject of much historical research. Previous studies of the queen and later saint have been undertaken from several different perspectives, including the biographical, institutional and hagiographical. In addition, some scholars have focused on her piety and later cult. Although a saint's miracles were one of the significant elements affecting the development of a cult, far less interest has been shown in the geopolitical importance of the miracles attributed to St Margaret and the relationship between the miracles and the saint's cult. The intention of this paper is to examine the miracles attributed to St Margaret and to identify their characteristics within the context of their contribution to, and influence in, the development of her cult.

Pragmatism and its consequences are central issues in American politics today, yet scholars rarely examine in detail the relationship between pragmatism and politics. This book systematically explores the subject and makes a strong case for adopting a pragmatist approach to democratic politics—and for giving priority to democracy in the process of selecting and reforming political institutions. What is the primary value of democracy? When should we make decisions democratically and when should we rely on markets? And when should we accept the decisions of unelected officials, such as judges or bureaucrats? This book explores how a commitment to pragmatism should affect our answers to such important questions. It concludes that democracy is a good way of determining how these kinds of decisions should be made—even if what the democratic process determines is that not all decisions should be made democratically. So, for example, the democratically elected U.S. Congress may legitimately remove monetary policy from democratic decision-making by putting it under the control of the Federal Reserve. This book argues that pragmatism offers an original and compelling justification of democracy in terms of the unique contributions democratic institutions can make to processes of institutional choice. This focus highlights the important role that democracy plays, not in achieving consensus or commonality, but rather in addressing conflicts. Indeed, the book suggest that democratic politics is perhaps best seen less as a way of reaching consensus or agreement than as a way of structuring the terms of persistent disagreement.

The advent of the Portable Antiquities Scheme (PAS) has added a great deal to our understanding of prehistoric metal artefacts in England and Wales, namely in expanding enormously the corpuses of objects previously thought to be quite scarce. One such artefact type is the miniature socketed 'votive' axe, most of which are found in Wiltshire and Hampshire. As a direct result of developing such recording initiatives, reporting of these artefacts as detector finds from the early 2000s onwards has virtually trebled the number originally published by Paul Robinson in his 1995 analysis. Through extensive data-collection, synthesising examples recorded via the PAS with those from published excavations, the broad aims of this paper (in brief) are as follows: firstly, produce a solid typology for these artefacts; secondly, investigate their spatial distribution across England and Wales. As a more indirect third aim, this paper also seeks to redress the imbalance of focus and academic study specifically applying to Hampshire finds of this object type, which despite producing a significant proportion of the currently known corpus have never been the subject of detailed analysis.
