AbstractThe subterranean termites in the genus Reticulitermes have a complex and plastic life cycle, which has been the subject of a number of publications over the past century. Given the inherent difficulties in studying such cryptic, eusocial organisms it is not perhaps surprising that the literature on their biology has failed to reach a consensus. An overview of the literature is given, which is followed by a discussion of the various theories on the life cycle of Reticulitermes spp. A substantial proportion of the review focuses on the French literature, which constitutes the majority of the primary sources and can be difficult to access. There are many discrepancies in the literature in terms of the number of instars, the definition of workers and the question of whether they should be termed pseudergates or, potentially, an additional terminology used to differentiate between pseudergates and the true workers seen in the higher termites (Isoptera: Termitidae). It remains very difficult to compare publications as there is little conformity; a problem that is aggravated by a general absence of drawings of the relevant instars. Further work on the biology of Reticulitermes is clearly required. There is also a need for researchers to agree on a standard terminology for this genus. A glossary is provided for the various synonyms and definitions.

Yet another survey of the much-traversed field of Anglo-German relations will seem to many historians of modern Europe to border on the realm of superfluity; probably no two countries have had their relationship to each other so frequently examined in the past century as Britain and Germany. Moreover, even if one restricted such a study to the British side alone, the sheer number of publications upon this topic, or upon only a section of it like the age of ‘appeasement’, is simply too great to allow a compression of existing knowledge into a narrative form that would be anything other than crude and sketchy. The following contribution therefore seeks neither to provide such a general survey, nor, by use of new and detailed archival materials, to concentrate upon a small segment of the history of British policy towards Germany in the period 1864–1939; but instead to consider throughout all these years a particular aspect, namely, the respective arguments of Germanophiles and Germanophobes in Britain and the connection between this dialogue and the more general ideological standpoints of both sides. In so doing, the author has produced a survey which remains embarrassingly summary in detail but does at least attempt to offer a fresh approach to the subject.

In the pantheon of approaches open to participants in the pacific settlement of disputes, good offices holds a noteworthy place. The evolution of good offices over the past century is concurrent with a trend of considerable transformation within international law, including – amongst other changes – a move away from a state-led legal order, including in good offices following the emergence of the heads of international organisations as its prime users, and a process of legalisation and specialisation within the subject that has entirely altered its character. These changes have led to a redefinition of good offices that stresses the actor carrying out the role above the form that it takes. To accompany these changes in practice, there is a need for a transformation in the legal analysis and definition of good offices. One potential option in achieving this end is Bell'slex pacificatoria. If good offices is to continue to play a significant role in the settlement of violent conflicts, a fully developed legal analysis is necessary to grasp both its historical development and its potential future role.

Marriage is a topic that has been dealt by Hollywood since the beginning of motion pictures. Even though the subject of marriage seems to be banal, there is a wide diversity in how people lead their married lives. Factors such as culture, religion, education, and history have major influences on the perception and definition of marriage. Hollywood, which has always been deft to notice the evolution in marriage, has accurately portrayed them through the use of movies. Through this paper, the researcher intends to chart the development in the concept of marriage through cinema over the past century.

Summary There is no need to repeat earlier complaints that the historiography of missionary linguistics was being neglected, since the situation has changed considerably sine the last decades of the past century. The first decade of the 21st century in particular has witnessed a veritable explosion of research activities. This article surveys the state of the art in the field of recent work in the historiographical subfield called ‘Missionary linguistics’, covering the period 2002–2012. It represents an update of Zimmermann (2004) and provides separate sections devoted to earlier studies of missionary linguistics, international conferences, published volumes, journals, reprints and editions of primary sources, exhibitions and other activities related to the subject. The reference list is divided in two sections, (1) primary sources, with some 140 entries, and (2) secondary sources, including more than 300 titles. It is hoped that this account will suggest several additional research topics and inspire scholars to make further advances in this fascinating field of research.

Although there are dozens of countries with present day border disputes, few have received such unrelenting international focus as Israel. Maps, cartography and geographic education support the developing doctrine of national boundaries that form collective national identity and ideology. Geographically, throughout the past century, the borders of Israel have become a melding of the phenomena of national identity with physical territory – also referred to as territorial socialization. My paper argues that Israel’s use of geographic description of borders specifically through cartography over time is an example of how boundaries are a powerful tool in the naturalization of ideology of Jewish Israelis. This argument is analyzed by examining historical and biblical cartography, territorial evolution, geography curriculum and textbooks, the Atlas of Israel and mental mapping by citizens. Varying portrayals of Israel’s historical, biblical, natural and political boundaries creates an ambiguous definition of Israel’s borders for citizens. In turn, this importantly shapes the present day religious and seculargeographies of the population of Israel as well as the political behaviours by the democratically representative Israeli government.

The goal of this research consists in identification and complex description of the stages of existence of a phrase. The subject of this research is changes in the use that afflict phrases in diachrony. The author determines the types of such changes, which characterize the stages of existence of a phrase since its emergence, as well as possible ways of development of a phrase (in terms of unchangeability of its composition and level of idiomaticity).Based on the material of verbal-nominal phrases in German language, both free and phraseologisms, and attraction of corpus-based data, the changes in use are perceived as elements of a single process. The scientific novelty lies in the attempt to describe the models of diachronic changes as cyclic processes; reveal common trends in development of phrases and in applicability of the definition of “life cycle” to the indicted processes. The concept of “life cycle”, used in various sciences for designating the natural, repeating processes, found its reflection in linguistics. However, cyclic processes in phraseology yet remain unstudied, despite the existing description of such phenomena as usualization, phraseologization, and dephraseologization. In conclusion, the author presents a dynamic model of life cycle of a phrase; the changes in use are viewed as its part; as well as offers the terms “deusualization” and “reusualization”. The obtained life cycle model can find application in further research in the area of diachronic phraseology and phrase formation.

The object of this research is the methods used in design practices of post-Soviet time to give historical appearance to landscapes of former estates of Moscow region, which faded away, i.e. the methods of historicization. The landscapes under review are being protected by the government as the objects of Moscow cultural heritage, and designated as museums (reserve museums) and public parks. The subject of this research is disclosure of the essence of these methods and their assessment from the perspective of alignment with historical primary sources, implementation, proliferation, and attractiveness. The author conducts systematization of methods in accordance to the degree of conformance to the historical realities, and divides them into the following groups: 1) that provide accurate reproduction of historical forms, 2) that create similarities, 3) that create new forms. Each group is divided into subgroups. By frequency of application, the leading place belongs to the methods of first group, which are aimed at reproduction of the shapes of buildings and structures. The rest two methods focus on reviving the memory of the past. The application is attributed to new construction, which can be assessed as landscape evolution and a modern artistic phenomenon. The methods of second group lead to landscape development in spirit of historicism, while the methods of third group – to the development of territory based on modern vision of the past. The conducted analysis is valued for the general outlook upon the process of preservation of one of the most complex types of cultural heritage of Moscow.

Little is known about how the age pattern in individual performance in cognitively demanding tasks changed over the past century. The main difficulty for measuring such life cycle performance patterns and their dynamics over time is related to the construction of a reliable measure that is comparable across individuals and over time and not affected by changes in technology or other environmental factors. This study presents evidence for the dynamics of life cycle patterns of cognitive performance over the past 125 y based on an analysis of data from professional chess tournaments. Individual move-by-move performance in more than 24,000 games is evaluated relative to an objective benchmark that is based on the respective optimal move suggested by a chess engine. This provides a precise and comparable measurement of individual performance for the same individual at different ages over long periods of time, exploiting the advantage of a strictly comparable task and a comparison with an identical performance benchmark. Repeated observations for the same individuals allow disentangling age patterns from idiosyncratic variation and analyzing how age patterns change over time and across birth cohorts. The findings document a hump-shaped performance profile over the life cycle and a long-run shift in the profile toward younger ages that is associated with cohort effects rather than period effects. This shift can be rationalized by greater experience, which is potentially a consequence of changes in education and training facilities related to digitization.

The article focuses on the debate on the conception of the author over the past century that has resulted in a series of attempts to undermine the position of the author and even remove this category from theoretical considerations (the idea of the death of the author). It points to a schizophrenic gap between critical theory and reading practice in which the author remains indispensable for interpretation. The theories that aim to exclude the author are based on certain paradoxes, such as regressus as infi - tivum when a text is treated as a combination of quotes or creatio ex nihilo when the author is completely erased. The second part of the article offers an analysis of Witkacy’s Gyuabal Wahazar with a view to showing the ways in which the authorial subject is constituted and bound to the author’s existence. It emphasizes the concomitant indispensability and indeterminacy of the subject.

Philosophy, in general, moves in a sphere of abstraction, and its statements claim to be necessary and of universal validity. The reader therefore expects them to appeal directly to his reason, and he does not normally reflect much on the time and historical conditions that determined what the philosopher took for granted. It is only in this age of historical consciousness that we have come to appreciate these factors more readily, and the great thinkers of the past appear to us more or less closely related to the culture of their age. The writings of Plato and Aristotle in particular are for us an inexhaustible source of information about Greek society and civilisation. This is true also in regard to the relation of Greek philosophy to the science of its time, and this is of special importance for our understanding. That relation can be traced throughout Aristotle's logical, physical, and metaphysical works; but the influence of other sciences and arts is no less evident in his ethics. In this paper I propose to examine the numerous references to medicine that occur in the Nicomachean Ethics. They are mostly concerned with the question of the best method of treating this subject. The problem of the right method is always of the utmost importance for Aristotle. The discussion of it begins on the first page of the Ethics, where he tries to give a definition of the subject of this course of lectures and attributes it to a philosophical discipline that he calls ‘politics’. He does so in agreement with the Platonic tradition. We can trace it back to one of the dialogues of Plato's first period, the Gorgias, in which the Platonic Socrates for the first time pronounces his postulate of a new kind of philosophy, the object of which ought to be the care of the human soul (φυχῆς θεραπεία). He assigns this supreme task to ‘political art’, even though it does not fulfil this function at present.
