The name of Lewis P. Orr is an honoured one in the history of medico-actuarial literature. It may well be claimed that his paper on “The selection of lives”(T.F.A. 8, page 103) and the revised edition (T.F.A. 13, page 181) were for many years the standard British works on the medical aspects of life assurance underwriting. His earlier paper (T.F.A. 6, page 55) on “Research in life assurance”—submitted to the Faculty in 1911—may, in its consequences, have been even more important because it set the actuaries of the time thinking, and from that, years later, arose the Continuous Mortality Investigation of the Institute and Faculty of Actuaries; but it is with the subject of the two later papers that we are now concerned.

AbstractThe aim of this article is to reveal the institutional dimensions of populism, which tend to be ignored because of the hegemony of economic analysis of the subject. Whereas many researchers assume that populism is a result of the negative economic effects of neoliberal policies on the middle class, I argue that populism is also a corollary of neoliberal institutions’ effect on the political power of so-called ordinary people. To illustrate this, I focus on the rhetoric of Turkish populists concerning two important economic institutions in Turkey: the Public Procurement Authority and the Central Bank. This examination shows that Turkish populists view the independent institutions of neoliberalism as a barrier against the people’s political will and define themselves as fighters for democracy.

The title, and subject, of this piece is ‘satisfaction’, though its main locus in time is the sixteenth and seventeenth centuries. I chose the subject because it fitted in with our president’s preoccupations, and because it interested me; it turns out, to my surprise, to jog our elbow about some contemporary matters, as I guess he wished.We had better start with the word, where there are two distinctions to be considered. The obvious one is between making up for, paying for, making amends, making reparation; and contentment, gratified desire, giving satisfaction, what you can’t get none of. I shall say that the first is the strong meaning, the second the weak one. The first is always other-directed, and entails an offence previously committed; the second is principally self-directed. ‘To content’ is a classical meaning of satisfacere, but it means to content someone else: to do something (facere), as against receiving something. A short history of the word in Latin and English records that the strong meaning emerged into late Latin as a description of church penance, and so passed into English in the fourteenth century. Its heyday was from then until the eighteenth. It referred to ecclesiastical penance (interrupted by the Reformation), the theology of the Redemption (encouraged by the Reformation), and in general public usage to the meeting of any kind of obligation, payment, atonement or compensation. From the eighteenth century it passed from public use, superseded by the weak meaning except in technical or professional fields. One professional usage, to which The Oxford English Dictionary gives a good deal of attention, is ‘to satisfy the examiners’: they think it is a case of ‘content’; may it be a case of ‘avert wrath’?

The north-west corner of Spain was long neglected by Roman archaeologists, who have tended to concentrate on the more spectacular remains to be found in the south and east. However, recently more attention has been directed there by workers of several nationalities, who have now produced a quite extensive literature on the gold mines, as well as on wider aspects, chiefly in connection with the activities of the legion VII Gemina. Yet there has been little attempt in all this to examine why a substantial military force was maintained in the region for so long. This paper aims to review that problem to about the end of the second century A.D. The evidence available is almost entirely epigraphic, chiefly consisting of epitaphs and religious dedications. Building inscriptions are scarce. For convenience all the epigraphic material from the north-west of Spain that is relevant to the disposition of the army is collected in the appendix, and in the main text reference will be made to the numbers given there. In addition a few historical passages are of importance, but the archaeological site evidence is very slight. The nature of the evidence is such that most attention must be devoted to the units attested in the region and their deployment, with little to be said about their actual bases. Previous work on the subject has been dominated by the late Antonio García y Bellido in several masterly papers. However it has tended to concentrate more on the history of the units themselves than on questions of topography and the reasons behind their presence.

Abstract This article focuses on China’s initial encounter with the African continent from the perspective of a select literature overview. It reflects on the very earliest contacts between dynastic China and ancient Africa and shows that the current contestation in the Western media as well as literature over this more recent contact is not new. Given the dearth and disparate nature of the information on these first encounters, it does this through the lens of what has been written on the subject of the speculated first contact in a selection of secondary English-language literature. It does so by considering the prevalence of such literature in three distinct periods: prior to 1949; from 1950 to 1990; and a selection of research published thereafter. It shows that China’s encounter with Africa reaches far back into the history of the continent, but more importantly so does the volatile contestation surrounding the contemporary contact.


Oxford Studies in Early Modern Philosophy is an annual series, presenting a selection of the best current work in the history of early modern philosophy. It focuses on the seventeenth and eighteenth centuries—the extraordinary period of intellectual flourishing that begins, roughly, with Descartes and his contemporaries and ends with Kant. It also publishes work on thinkers or movements outside of that framework, provided they are important in illuminating early modern thought. The core of the subject matter is philosophy and its history. But the volume’s chapters reflect the fact that philosophy in the early modern period was much broader in its scope than it is currently taken to be and included a great deal of what now belongs to the natural sciences. Furthermore, philosophy in the period was closely connected with other disciplines, such as theology, law and medicine, and with larger questions of social, political, and religious history. Volume 10 includes chapters dedicated to a wide set of topics in the philosophies of Thomas White, Spinoza, Locke, Leibniz, and Hume.

“History Research Commission” staged by Alvis Hermanis in New Riga Theatre (2019) is an example of post-truth coming onto the theatre stage in terms of a rather sensitive subject – historical traumas and unsolved issues that still influence today’s society in Latvia. Hermanis’s production accepts the post-truth as an inevitable and obvious present framework of modern thinking; meanwhile, the subject itself (“cheka bags”) implies the impossibility to find out any “truth” due to its distorted nature from the very beginning. “History Research Commission” paradoxically leads to conclude that the post-truth approach in theatre might be the most honest in terms of today’s world, where the truth has lost its previous status of value. The article covers the short history of “post-truth” analysed by Ralph Keyes, Lee McIntyre, and Yael Brahms. It aims to apply the notion to performing arts through the example of KGB’s experiences in Hermanis’s production (co-created with the actors of the New Riga Theatre) that seems to accept the post-truth and the tragedy of Western rationalism facing the impossibility to find out the provable truth regarding certain subjects. The message of absurdity to chase the truth in “cheka bags” confirms post-truth as the status quo of our time.

AbstractThis review contains a brief history of the use of insecticides. The peculiarities, main advantages, and disadvantages of some modern insecticides are described. The names of the discoverers of some of the most popular insecticide preparations on the world market, are listed. The tendencies to find new insecticides to control the quantity of phytophagous insects are discussed. Special attention is paid to the perspective of creating preparations based on nucleic acids, in particular DNA insecticides. The use of insect-specific, short single-stranded DNA fragments as DNA insecticides, is paving the way in the field of “intellectual” insecticides that “think” before they act. It is worth noting, though, that in the near future, the quantity of produced insecticides will increase due to the challenges associated with food production for a rapidly growing population. It is concluded, that an agreeable interaction of scientists and manufacturers of insecticides should lead to the selection of the most optimal solutions for insect pest control, which would be safe, affordable, and effective at the same time.
