Modern surgery is difficult to imagine without mechanical stapling devices. The objective of the study was to trace the continuity of the development of mechanical stapling technology by European and American surgeons. The main step that led to this technological development was the idea of using a simple paper staple for suturing of human tissue. The first time the mechanical stapling device was used on a human was 9th May, 1908 in Budapest. Subsequently, surgeons and engineers of Europe, primarily Hungary (Austria-Hungary) (H. Hultl, V. Fischer, A. von Petz, etc), Germany (H. Friedrich, etc.) and the USSR (V. Gudov, V. Demikhov, P. Androsov, etc) refined the mechanical principles and practical implications of this new technology. By the mid-1950s, two types of devices were manufactured in the USSR for simple suturing tissues such as the pulmonary parenchyma or bronchus and for the construction of anastomosis. The disadvantages of these devices could be attributed the requirement of delicate manual loading of small metal staples into the cartridge and assembling of sterile parts immediately prior to application. A group of surgeons and engineers led by an American thoracic surgeon, Mark Ravitch, managed to overcome these disadvantages by making devices user-friendly, launched their production in the USA and even organized a training network for surgeons wishing to use the new instruments. The history of mechanical stapling devices illustrates the successful realization of novel ideas that were supported by technological advances and the professional ambitions of surgeons.

The article analyses the issue of the NATO missile defense development and the evolution of views in the Russian political, military and expert circles. In 2009, the U. S. President Baraсk Obama declared a start of the NATO missile defense system construction with a goal to be able to intercept a limited nuclear strike from Iran. Russia is in doubt about the stated purpose of the European missile defense and considers it to be a threat to its own strategic nuclear forces. The European missile defense construction has been experiencing technical obstacles and political difficulties: the cancellation of deployment of interceptor SM‑3 IIB and delays in establishing operational capability of the Aegis Ashore land-based missile defense system in Poland. The current architecture of the NATO missile defense, which allows only to intercept a limited number of incoming warheads, has no significant impact on Russian retaliatory strike capability. Nevertheless, the missile defense in Europe remains an irritating factor in relations between Russia and the USA. Apparently, Biden’s arrival in the White House creates an opportunity for parties to address the issue during negotiations on the New START follow-on Treaty. The research addresses the history of Russia–USA–NATO cooperation on theatre missile defense and the reasons for the failure of the joint missile defense in Europe. The author justifies the reanimation of the Joint Data Exchange Center project and outlines the idea of its transformation to the Multilateral Data Exchange Center. Acknowledgments.

Восстановление надводного флота Российской империи в 1906–1917 гг. происходило в условиях революционных сдвигов в мировой кораблестроительной технике. Произошел переход от традиционных поршневых паровых машин в качестве главного двигателя к турбинным механизмам. Для самостоятельного изготовления судовых турбин машиностроительным заводам в империи не хватало мощного металлургического оборудования и технологического опыта. В условиях спешной подготовки к войне правительство пожертвовало традиционным официальным принципом — строить все у себя, из отечественных материалов, своими силами. Турбинные двигатели для всех классов кораблей царский флот получал из Германии, Англии, Швейцарии и США. В России же производство турбин в основном сводилось к механической обработке стальных заготовок, полученных от зарубежных поставщиков, и последующей сборки под руководством специалистов из авторитетных в данной области западных фирм. В историографии вопроса наблюдается систематическое противоречие: достоверное фактически описание кораблестроительной практики, как правило, опровергает обобщения, основанные на преувеличенных представлениях о достигнутом заводской техникой России научно-производственном уровне. The restoration of the Imperial Russian surface fleet in 1900–1917 took place during major technological shifts in world shipbuilding. It was the time of transition from traditional reciprocating steam engines to turbine mechanisms. The Empire’s machine-building plants lacked powerful metallurgical equipment and technological experience required for production of ship turbines. Within the circumstances of rapid war preparations, the government shifted from traditional principles of self-production, towards using international resources and powers. The Imperial Russian Navy was supplied by turbine engines for all classes of ships by Germany, England, Switzerland and the USA. Turbine engines in Russia were manufactured by processing steel templates provided by foreign suppliers. Further construction of the engines took place under the supervision of experienced western entities. A systematic contradiction in the historiography on this issue can be seen. The author reveals a verified factually based descriptions of the shipmanufacturing process, and disapproves past general conclusions, which were based on the exaggerated notions about the level of Russian scientific and technological development.

We have long recognized technology as a driving force behind much historical and cultural change. The invention of the printing press initiated the Reformation. The development of the compass ushered in the Age of Exploration and the discovery of the New World. The cotton gin created the conditions that led to the Civil War. Now, in Beyond Engineering, science writer Robert Pool turns the question around to examine how society shapes technology. Drawing on such disparate fields as history, economics, risk analysis, management science, sociology, and psychology, Pool illuminates the complex, often fascinating interplay between machines and society, in a book that will revolutionize how we think about technology. We tend to think that reason guides technological development, that engineering expertise alone determines the final form an invention takes. But if you look closely enough at the history of any invention, says Pool, you will find that factors unrelated to engineering seem to have an almost equal impact. In his wide-ranging volume, he traces developments in nuclear energy, automobiles, light bulbs, commercial electricity, and personal computers, to reveal that the ultimate shape of a technology often has as much to do with outside and unforeseen forces. For instance, Pool explores the reasons why steam-powered cars lost out to internal combustion engines. He shows that the Stanley Steamer was in many ways superior to the Model T--it set a land speed record in 1906 of more than 127 miles per hour, it had no transmission (and no transmission headaches), and it was simpler (one Stanley engine had only twenty-two moving parts) and quieter than a gas engine--but the steamers were killed off by factors that had little or nothing to do with their engineering merits, including the Stanley twins' lack of business acumen and an outbreak of hoof-and-mouth disease. Pool illuminates other aspects of technology as well. He traces how seemingly minor decisions made early along the path of development can have profound consequences further down the road, and perhaps most important, he argues that with the increasing complexity of our technological advances--from nuclear reactors to genetic engineering--the number of things that can go wrong multiplies, making it increasingly difficult to engineer risk out of the equation. Citing such catastrophes as Bhopal, Three Mile Island, the Exxon Valdez, the Challenger, and Chernobyl, he argues that is it time to rethink our approach to technology. The days are gone when machines were solely a product of larger-than-life inventors and hard-working engineers. Increasingly, technology will be a joint effort, with its design shaped not only by engineers and executives but also psychologists, political scientists, management theorists, risk specialists, regulators and courts, and the general public. Whether discussing bovine growth hormone, molten-salt reactors, or baboon-to-human transplants, Beyond Engineering is an engaging look at modern technology and an illuminating account of how technology and the modern world shape each other.

The Great Leap Forward

In 1949, at the end of a long period of wars, one of the biggest challenges facing leaders of the new People's Republic of China was how much they did not know. The government of one of the world's largest nations was committed to fundamentally reengineering its society and economy via socialist planning while having almost no reliable statistical data about their own country. This book is the history of efforts to resolve this “crisis in counting.” The book explores the choices made by political leaders, statisticians, academics, statistical workers, and even literary figures in attempts to know the nation through numbers. It shows that early reliance on Soviet-inspired methods of exhaustive enumeration became increasingly untenable in China by the mid-1950s. Unprecedented and unexpected exchanges with Indian statisticians followed, as the Chinese sought to learn about the then-exciting new technology of random sampling. These developments were overtaken by the tumult of the Great Leap Forward (1958–1961), when probabilistic and exhaustive methods were rejected and statistics was refashioned into an ethnographic enterprise. By acknowledging Soviet and Indian influences, the book not only revises existing models of Cold War science but also globalizes wider developments in the history of statistics and data. Anchored in debates about statistics and its relationship to state building, the book offers fresh perspectives on China's transition to socialism.

The Impact

The history of human society is replete with examples of advances in technology overrunning the ability of societal organizations to efficiently handle the resulting massive societal dislocations. The social impacts of the “Industrial Revolution of the 18th and 19th Centuries” illustrate how profound such effects can be. The automation-computer-robotics revolution now underway also has the potential for serious societal changes. In this regard public works activities are subject to increasing amounts of automation with impacts upon current and net total employment and training needs. To evaluate the present status of automation in the USA, questionnaires were sent to public works authorities in 110 cities or agencies. The current degree of automation, the impact upon employment and the skills now needed by public works employers were queried. It was found that in most cases automation was just starting; but that as complete automation as was possible was inevitable given the increasing complexity of the tasks, the demands of the public and the long term prospects for public works funding. In many cases the candidates now in the work force were not properly trained for automation needs. Retraining and changes in the educational system appeared necessary if the employees now needed were to be continuously available. Public works management as well as several labor organizations appeared to be aware of this need and were organizing to handle the training problem and the changes in employment qualifications now necessary. It appeared to be a consensus that the larger societal effects of automation should be handled by society as a whole.

It’s easy to get swept up in the excitement of new technology that appears to have potential to transform everything, including education. But, as Rafael Heller explains, educators have a long history of being seduced by technologies that never really lived up to their promise. That’s no reason to ignore technology’s potential, but plenty of reason to be realistic about what it can achieve.

Abstract In this essay, I offer a brief history of manuscript cataloguing and some observations on the innovations this practice introduced especially in the digital form. This history reveals that as the cataloguing of medieval manuscripts developed over time, so did the research needs it served. What was often considered traditional cataloguing practices had to be mediated to accommodate new scholarly advance, posing interesting questions, for example, on what new technologies can bring to this discussion. In the digital age, in particular, how do digital catalogues interact with their analogue counterparts? What skills and training are required of scholars interacting with this new technology? To this end, I will consider the importance of the digital environment to enable a more flexible approach to cataloguing. I will also discuss new insights into digital projects, especially the experience accrued by the The Production and Use of English Manuscripts 1060 to 1220 Project, and then propose that in the future cataloguing should be adaptable and shareable, and make full use of the different approaches to manuscripts generated by collaboration between scholars and librarians or the work of postgraduate students and early career researchers.
