In its early years, the disk drive industry was led by a group of large-scale, integrated firms of the sort that Alfred D. Chandler, Jr., observed in his studies of several of the world's largest industries. The purpose of this history is to explore why it was so difficult for the leading disk drive manufacturers to replicate their success when technology and the structure of markets changed. The most successful firms aggressively developed the new component technologies required to address their leading customers’ needs, but this attention caused leading drive makers to ignore a sequence of emerging market segments, where innovative disk drive technologies were deployed by new entrants. As the performance of these new-architecture products improved at a rapid pace, the new firms were eventually able to conquer established markets as well. As a consequence, most of the integrated firms that established the disk drive industry were driven from it, displaced by networks of tightly focused, less integrated independent companies.

In Bigger Than Life Mary Ann Doane examines how the scalar operations of cinema, especially those of the close-up, disturb and reconfigure the spectator's sense of place, space, and orientation. Doane traces the history of scalar transformations from early cinema to the contemporary use of digital technology. In the early years of cinema, audiences regarded the monumental close-up, particularly of the face, as grotesque and often horrifying, even as it sought to expose a character's interiority through its magnification of detail and expression. Today, large-scale technologies such as IMAX and surround sound strive to dissolve the cinematic frame and invade the spectator's space, “immersing” them in image and sound. The notion of immersion, Doane contends, is symptomatic of a crisis of location in technologically mediated space and a reconceptualization of position, scale, and distance. In this way, cinematic scale and its modes of spatialization and despatialization have shaped the modern subject, interpolating them into the incessant expansion of commodification.

This chapter surveys the history of vaccine research and development in China's wartime hinterlands during the early years of the Second Sino-Japanese War, considering first a major project launched by the League of Nations Health Organization (LNHO) and then, in turn, the major cities of Chongqing, Guiyang, and Lanzhou. Although urban areas were not the only places where medical researchers, students, and administrators worked, they were significant hubs for coordination and exchange. The development of vaccine production in cities coincided with the deployment of new and coercive strategies for immunization, reflecting the ongoing militarization of Chinese society. Yet many urban dwellers welcomed vaccination as a means of defending themselves against disease at a time when the Japanese offensive threatened to cause epidemic catastrophe both directly, through biological warfare, and indirectly, by causing large-scale migrations of refugees and soldiers across the country. Attempts to establish a certification system that connected immunization status to free passage on ships and roads suggested the increasing importance of biology to individual rights and freedoms in wartime China.

The history of the society development and its scientific and technological progress is constantly correlated with the history of wars. The desire to raise a person’s standard of living, the rapid pace of life and the aspiration to its high quality have always depended on inventions, technological innovations and the continuous process of development. Military science and the military industry are no exception. The importance of using modern technologies and precision intellectual weapons in a 21st century war is discussed. The issue of reconnaissance drones and the kinetic-strike capability of drones in combat is highlighted, as well as their support by space-based systems. This opened a new era in the art of modern warfare and pointed to the transformation of modern warfare. The article discusses features that have actually emerged in combat in airspace and cyberspace. All the challenges and problems that accompany military decision-making process are shown in the synthesis of these actions. The role and significance of reconnaissance and fighter drones in modern large-scale or local combat operations, especially for a small country like Georgia, are also discussed.

Stephen Hawking's contributions to the understanding of gravity, black holes and cosmology were truly immense. They began with the singularity theorems in the 1960s followed by his discovery that black holes have an entropy and consequently a finite temperature. Black holes were predicted to emit thermal radiation, what is now called Hawking radiation. He pioneered the study of primordial black holes and their potential role in cosmology. His organization of and contributions to the Nuffield Workshop in 1982 consolidated the picture that the large-scale structure of the universe originated as quantum fluctuations during the inflationary era. Work on the interplay between quantum mechanics and general relativity resulted in his formulation of the concept of the wavefunction of the universe. The tension between quantum mechanics and general relativity led to his struggles with the information paradox concerning deep connections between these fundamental areas of physics. These achievements were all accomplished following the diagnosis during the early years of Stephen's studies as a post-graduate student in Cambridge that he had incurable motor neuron disease—he was given two years to live. Against all the odds, he lived a further 55 years. The distinction of his work led to many honours and he became a major public figure, promoting with passion the needs of disabled people. His popular best-selling book, A brief history of time , made cosmology and his own work known to the general public world-wide. He became an icon for science and an inspiration to all.

In 1993, four years prior to the publication of Clayton Christensen's highly influential book, The Innovator's Dilemma, the Business History Review published an article by Christensen titled “The Rigid Disk Drive Industry: A History of Commercial and Technological Turbulence.” The article relates the theory of disruptive innovation to Alfred D. Chandler's work on large vertically integrated enterprises. It was published during a pivotal era of scholarship on innovation, management practice, and industry evolution, much of which used the history of firms, industries, and technologies to build theory. I survey the impact and critiques of Christensen's research agenda, highlighting how it illustrates where the boundaries associated with the “lessons of history” should be drawn.

The report is based on the first results of the study "The History of the Evangelical Christians-Baptists in Ukraine", carried out in 1994-1996 by the joint efforts of the Department of Religious Studies at the Institute of Philosophy of the National Academy of Sciences of Ukraine and the Odessa Theological Seminary of Evangelical Christian Baptists. A large-scale description and research of archival sources on the history of evangelical movements in our country gave the first experience of fruitful cooperation between secular and church researchers.
