It is a great honour for me to address the members of the oldest learned society devoted to aeronautics, the Royal Aeronautical Society, which was founded in 1866—six years before the Société Francaise de Navigation Aérienne of France was founded for the same purpose.The choice of a subject nowadays is a difficult matter; great progress has been made in aeronautical science—numerous research workers all over the world are endeavouring to solve the outstanding problems—and the reason I decided to take for my lecture the subject of the maximum speeds of commercial aeroplanes was that it appears to me to be a matter of the utmost importance for the future of commercial aeronautics and for linking up the different peoples of the globe.

Ever since the Charter of the United Nations was signed in 1945, human rights have constituted one of its three pillars, along with peace and development. As noted in a dictum coined during the World Summit of 2005: “There can be no peace without development, no development without peace, and neither without respect for human rights.” But while progress has been made in all three domains, it is with respect to human rights that the organization's performance has experienced some of its greatest shortcomings. Not coincidentally, the human rights pillar receives only a fraction of the resources enjoyed by the other two—a mere 3 percent of the general budget.

The subject of this essay is Andrzej Waśkiewicz’s book Ludzie – rzeczy – ludzie. O porządkach społecznych, gdzie rzeczy łączą, nie dzielą (People–Things–People: On Social Orders Where Things Connect Rather Than Divide People). The book is the work of a historian of ideas and concerns contemporary searches for alternatives to capitalism: the review presents the book’s overview of visions of society in which the market, property, inequality, or profit do not play significant roles. Such visions reach back to Western utopian social and political thought, from Plato to the nineteenth century. In comparing these ideas with contemporary visions of the world of post-capitalism, the author of the book proposes a general typology of such images. Ultimately, in reference to Simmel, he takes a critical stance toward the proposals, recognizing the exchange of goods to be a fundamental and indispensable element of social life. The author of the review raises two issues that came to mind while reading the book. First, the juxtaposition of texts of a very different nature within the uniform category of “utopia” causes us to question the role and status of reflections regarding the future and of speculative theory in contemporary social thought; second, such a juxtaposition suggests that reflecting on the social “optimal good” requires a much more precise and complex conception of a “thing,” for instance, as is proposed by new materialism or anthropological studies of objects and value as such.

The method of calculating the values of prospective pensions which I am about to describe differs in some respects from those given in the standard papers on the subject, and will be found, I think, to possess advantages of its own. I shall deal with its application to the case of pensions based on salaries, when the amount of the pension is a uniform percentage of salary for each year of service taken account of.I have followed Mr. Manly in the use of the following symbols (see his paper of 1901—J.I.A. xxxvi, 209), namely, lx to denote the number living and remaining on the active list at age x as given in the Service Table, and Dx and Nx to correspond; rx to denote the number retiring from failure of health between ages x and x + 1, sx to denote the salary receivable between ages x and x + 1, and Dsx to denote Dx X sx. When however lx, Dx, Nx, or Dsx have a circumflex accent, these symbols have the ordinary meanings, and the functions are based respectively on the Pensioners Mortality Table. I have found it necessary to employ also a certain number of new symbols which are described in the Key to the Special Notation (see pp. 31, 32). I have also followed Mr. Manly in the assumptions made in the paper mentioned above, that the retirements or superannuations applicable to any year of age take place at the end of the year, and that the pension commences at the same time and is payable yearly thereafter.

Many states have undertaken language and terminology planning programmes and have reached the point where they must evaluate the progress realized up to the present time. In the case of terminology planning programmes, such an evaluation requires a method to measure the degree to which the terminology has been implanted. In this paper, a research protocol for measuring terminology implantation is presented; this protocol is based on institutional communications. First, a critical examination of prior research on the subject is made in order to identify the desired characteristics of a precise, scientific measurement protocol. It is an accepted postulate that the constitution of a representative corpus forms the basis of a solution. Statistical sampling methods have been adapted in order to design a measurement protocol that respects the above conditions. The paper concludes with an overview of the results of a terminology implantation survey carried out using the research protocol presented; the survey concerns transportation terminology. This overview is followed by a brief discussion of the future possibilities offered by the scientific measurement of terminology implantation.

Abstract Lung cancer is one of the most leading causes of death throughout the world, and there is an urgent requirement for the precision medical management of it. Artificial intelligence (AI) consisting of numerous advanced techniques has been widely applied in the field of medical care. Meanwhile, radiomics based on traditional machine learning also does a great job in mining information through medical images. With the integration of AI and radiomics, great progress has been made in the early diagnosis, specific characterization, and prognosis of lung cancer, which has aroused attention all over the world. In this study, we give a brief review of the current application of AI and radiomics for precision medical management in lung cancer.

This essay presents two interviews with Dario Argento, one conducted by Élie Castiel and the other by Stephane Derderian. In the Castiel interview, Argento talks about early influences on his career; his approach to every film; eroticism and sadism as well as the question of voyeurism in his work; the importance of objects in the genre films that he has made; and the future of horror films. In the Derderian interview, Argento shares his thoughts on the bloodiness in Deep Red; what the subject of visual memory that often comes up in his films such as The Bird with the Crystal Plumage represent for him; the place of homosexuality in his films; why people who see his films don't look for a suspect as much as they look for a truth; the psychology of the murderer vs. the psychology of the investigator in his films; and the presence of the world of painting in Deep Red, The Bird with the Crystal Plumage, and The Stendhal Syndrome.


In spite of the great progress which has been made in the study of Coal Measure plants, the subject of leaf structure has been largely neglected. The author is investigating the structure of the leaves of the principal groups of palæozoic plants with the view of determining their morphological and biological characters, and also of obtaining some knowledge of the conditions under which they grew. The speimens of Calamite leaves described in this paper have been found chiefly in slides in existing collections, and most of the material originally came from the Halifax Hard Bed of the Lower Coal measures.

AbstractWhen the present epoch is described as “Anthropocene” human choice is seen as essential to the planet’s future. This essay accepts this presupposition of choice and demonstrates its consequences upon the religions of the world. It does this first by describing what human choices must be made in order to bring about a healthy planet; then provides a way of expanding the current definitions of “religion” so these new social realities will be recognized in the future. It describes in detail how religions have interfaced with planetary necessities in the past and present. Presupposing that the religions of the world have been a force of good as well as ill, it describes what must happen in both the classical as well the newer forms of religion to enable the future environmental changes to be for the good of humanity.

If the twenty-sixth year of the World Court has not been one of intense activity, it has been marked by events of some significance for the future. The single session held by the Court during the year was devoted to administrative questions, largely to those growing out of the reorganization of the previous year. One proceeding was instituted before the Court, the first since its reorganization, and the Court was seized of one request for an advisory opinion emanating from the General Assembly. Some progresswas made in the extension of the Court’s jurisdiction, and a series of resolutions concerning the Court was adopted by the General Assembly on November 14, 1947.

Osteoarthritis is a very common cause of chronic pain in dogs and cats. Great progress has been made in the last 2–3 decades in unravelling the molecular mediators of joint pain. Now we are starting to see the benefits of this research in terms of new targets to block joint pain and new medicines reaching our pharmacy shelves. This review summarises the progress that has been made in understanding why and how arthritic joints cause pain. This will help readers understand novel medicines and provide insight into the others that might follow in the future.
