Decision-making for the management of valvular disease (VHD) is rapidly evolving with advances in surgical and interventional techniques. The main causes of VHD has moved from rheumatic to degenerative, more particularly in industrial countries. In this chapter will be briefly discuss the aetiologies, presentation, and natural history of VHD in adults. The medical and surgical options available to date and the threshold for intervention will be then described. The role of a multidisciplinary Heart Valve Team working together with a geriatrician has become crucial to determine the optimal therapeutic option for VHD in older adults. Surgical valve replacement has been for decades the only possible option for the three leading VHDs in developed countries: aortic stenosis (AS), aortic regurgitation (AR) and mitral regurgitation (MR). Mitral stenosis (MS) has almost disappeared in Western countries while its prevalence remains high in the developing world.

AbstractIntuitions guide decision-making, and looking to the evolutionary history of humans illuminates why some behavioral responses are more intuitive than others. Yet a place remains for cognitive processes to second-guess intuitive responses – that is, to be reflective – and individual differences abound in automatic, intuitive processing as well.

The problem of representation is central to all discussions of the functions of legislatures or the behavior of legislators. For it is commonly taken for granted that, in democratic political systems, legislatures are both legitimate and authoritative decision-making institutions, and that it is their representative character which makes them authoritative and legitimate. Through the process of representation, presumably, legislatures are empowered to act for the whole body politic and are legitimized. And because, by virtue of representation, they participate in legislation, the represented accept legislative decisions as authoritative. But agreement about the meaning of the term “representation” hardly goes beyond a general consensus regarding the context within which it is appropriately used. The history of political theory is studded with definitions of representation, usually embedded in ideological assumptions and postulates which cannot serve the uses of empirical research without conceptual clarification.

This paper explores the decision-making processes used by the inhabitants of Goma during the Kivu Crisis in October 2008. The paper's aim is twofold: After providing a short history of the October 2008 events, it seeks in the empirical part to distinguish and clarify the role of rumours and narratives in the setting of violent conflict as well as to analyse their impact on decision-making processes. As the epistemological interest lies more on the people who stay rather than those who flee, in the second part the paper argues that the practice of routinization indicates a conscious tactic whose purpose is to counter the non-declared state of exception in Goma. Routinization is defined as a means of establishing order in everyday life by referring to narratives based on lived experiences.

The Six Day War was one of the most defining moments in the history of the Modern Middle East. This paper seeks to add to the existing scholarship on the subject by going beyond the structural explanation. It gives special attention to the role of unit-level variables like perception, personality, and political psychology of decision-makers. As one scholar noted, threats are not perceived in a vacuum, and are, instead, products of complex synthesis of subjective appraisal of events by the decision-makers. The focus will be on the beliefs and perceptions of the most impactful actor in this crisis: Egyptian President Nasser. As will be argued, his decision-making was shaped by his experience with foreign imperialism, a general misconception of super power intentions, an incorrect analogy between two crucial crisis situations with Israel: the February 1960 Rotem Crisis, and the build-up to the June War in 1967, and especially his complicated relations with the US leaders.

Opinion differs about the role of syndicated columnists in the forming of national opinion and in the decision-making process in the United States. Our columnists have been the subject of pioneering studies, but we have a long way to go before the picture can be called historically complete, scientifically precise, or fully satisfactory for policy-making purposes. What the columnists say is an important chapter in the history of the American public, and history is most useful for critical purposes when written close to the event. The general theory of communication and politics can be refined as the details of the opinion process are more fully known.

The paper presents historical facts about the building and development of cosmonaut preflight training complex at the Baikonur Cosmodrome in the sixties of the last century. The role of some leaders of the space industry and the Ministry of Defense in substantiating and decision-making on the subject of creation and development of the training facilities is shown. The need to develop the training complex in order to tackle growing tasks of the Russian manned space program is briefly substantiated. The second stage of building individual elements of the complex, their role in providing cosmonaut preflight training is described.

Anyone with so much as a passing familiarity with bioethics knows how significantly and persistently (at least since mid-century) the law has insinuated itself into healthcare and the process of bioethical decisionmaking. Viewed from the insular perspective of traditional medical practice and medical ethics, it is not surprising that the “legalization” of the patient–physician relationship and clinical judgment has been characterized by some as pernicious. What is much more surprising, however, is when a book by a professor of law evinces the same jaundiced view of the role of law in this area. Nonetheless, the “limits” that Professor Dworkin considers to be inherent in the capacity of the law to resolve bioethical issues are significant, and hence in his opinion the role of the law should be severely circumscribed. This gloomy portrait of the “havoc” wreaked by law upon the landscape of medical practice, painted by a lawyer, stands in stark contrast to an earlier and much more sympathetic account offered by Columbia University historian and medical humanities professor David J. Rothman in his 1991 book Strangers at the Bedside, the informative subtitle of which is A History of How Law and Bioethics Transformed Medical Decision Making.

ABSTRACT Early efforts to bring particle accelerators into Brazil exemplify the interactions between advanced scientific countries and the periphery in the years 1948––1956 and between the history of science and the history of foreign affairs. The physicists Cesar Lattes, Ernest Lawrence, Herbert Anderson, Isidor Rabi, and Rear Admiral ÁÁlvaro Alberto played central roles in these efforts. The story brings out the role of the military and scientists acting within the Centro Brasileiro de Pesquisas Fíísicas and the Conselho Nacional de Pesquisas to promote nuclear physics research aimed at the development of nuclear technology in Brazil. The decision-making process involved science, politics, secret agreements, and international affairs.

AbstractIn our reply to Elise van Nederveen Meerkerk’s “Big Questions and Big Data: The Role of Labour and Labour Relations in Recent Global Economic History”, we focus on her observations on the Global Collaboratory on the History of Labour Relations. We endorse many of her suggestions to connect global labour and economic history and to regard labour relations not only as a dependent variable. In fact, as the examples from various Collab workshops and publications show, some of these ideas are already being put into practice. These examples also show that if we seriously want to combine global labour and economic history data and join the debate on the growth (or decrease) in social inequality, workers’ individual and collective agency must be taken on board. Finally, we argue that global labour and economic historians can benefit most from each other’s disciplines by truly working together in collaborative projects, developing new theories, perhaps less grand than those with which economic historians attract so much attention, but more profound.

AbstractThis chapter explores the history of the Greek diasporic community of Jerusalem in late Ottoman times and the formative years of the British Mandate. It focuses on the creation of the Greek Colony and its central community institution, the so-called Greek Club, as well as the role of Greek cultural diplomacy both with the Greek community and with Arabs of the Greek Orthodox denomination, in its development. It addresses the establishment and development of the Jerusalem Greek diaspora; its relation to the Greek state; and its links to the Orthodox Patriarchate. Overall, the chapter suggests that Greece could influence, but not control, the decision-making process within the community. The Greek diaspora was excluded from systematic influence in Church administration, lacking power over communal education, and hence politically dependent on the Church.
