Since its inception in 1984, Computerized Occlusal Analysis technology has revolutionized both dental Occlusal Science and daily clinical practice, by bringing objective precision measurement to the largely subjectively analyzed Dental Medicine discipline of Occlusion. The evolution of this technology has required much iteration over the past 30 years beginning with T-Scan I, then T-Scan II for Windows®, to T-Scan III with Turbo recording, to the present day version known as T-Scan 8. Numerous authors since the mid-1980s have studied the various T-Scan versions, which inspired the manufacturer to improve the hardware and its recording sensors to be more accurate, repeatable, and precise. The software has also evolved such that the present day T-Scan 8 includes many high-tech measurement tools that aid the clinician in diagnosing and treating a wide range of occlusal abnormalities. This chapter's specific aims are to detail the evolution of the differing T-Scan system versions while describing the many scientific studies that inspired important system improvements to the T-Scan's accuracy and repeatability from version to version.

Since its inception in 1984, Computerized Occlusal Analysis technology has revolutionized both dental Occlusal Science and daily clinical practice, by bringing objective precision measurement to the largely subjectively analyzed Dental Medicine discipline of Occlusion. The development of this technology has required much iteration over the past 30 years beginning with T-Scan I, then T-Scan II for Windows®, then T-Scan III with Turbo recording, to a simplified desktop version introduced in T-Scan 8, to the present-day, state-of-the-art occlusal analysis version known as T-Scan 10. Numerous authors since the mid-1980s have studied the various T-Scan versions, which inspired the manufacturer to improve the hardware and its recording sensors to be more accurate, repeatable, and precise. The present day Novus recording handle represents a major ergonomic and functional upgrade over the Evolution handle that was used up to T-Scan 8, while the T-Scan 9 software has evolved into T-Scan software Version 10, which includes many new high-tech measurement tools like the Digital Impression Overlay (DIO), the Sensitivity Wizard, the Implant Warning feature, and the Force Eraser tool. All of these new system modifications improve the clinician's ability to diagnose and treat a wide range of occlusal abnormalities. Chapter One's Specific Aims are to detail the evolution of the differing T-Scan system versions, while describing the many scientific studies that inspired important system improvements to the T-Scan's accuracy and repeatability, from version to version.

This essay derives from the primary need to make order between direct and indirect sources available for the reconstruction of the history of video art in Italy in the seventies. In fact, during the researches for the Ph.D. thesis it became clear that in most cases it is difficult to define, in terms of facts, which of the different historiographies should be taken into consideration to deepen the study of video art in Italy. Beyond legitimate differences of perspectives and methods, historiographical narratives all share similar issues and narrative structure. The first intention of the essay is, therefore, to compare the different historiographic narratives on Italian video art of the seventies, verifying their genealogy, the sources used and the accuracy of the narrated facts. For the selection of the corpus, it was decided to analyze in particular monographic volumes dealing with the history of the origins of video art in Italy. The aim was, in fact, to get a wide range of types of "narrations", as in the case of contemporary art and architecture magazines, which are examined in the second part of the essay. After the selection, for an analytical and comparative study of the various historiography, the essay focuses only on the Terza Biennale Internazionale della Giovane Pittura. Gennaio ’70. Comportamenti, oggetti e mediazioni (Third International Biennial of Young Painting. January '70. Behaviors, Objects and Mediations, 1970, Bologna), the exhibition which - after Lucio Fontana's pioneering experiments - is said to be the first sign of the arrival of videotape in Italy (called at the time videorecording), curated by Renato Barilli, Tommaso Trini, Andrea Emiliani and Maurizio Calvesi. The narration given so far of this exhibition appeared more mythological than historical and could be compared structurally to that of the many numerous beginnings that historiographyies on international video art identify as ‘first’ and ‘generative’. In the first part of the essay the 'facts' related to Gennaio ’70, as narrated by historiography on video art, are compared. In the second part the survey is carried out through some of the direct sources identified during the research, with the aim of answering to questions raised by the comparison between historiographies. Concluding, it is important to underline that the tapes containing the videos transmitted have not been found and seem to have disappeared since the ending of the exhibition. Nevertheless, the deepening of the works and documentation transmitted during the exhibition is possible thanks to other types of sources which give us many valuable information regarding video techniques and practices at the beginning of 1970 in Italy.

As an intellectual tradition, the history of Hegelianism is the history of the reception and influence of the thought of G.W.F. Hegel. This tradition is notoriously complex and many-sided, because while some Hegelians have seen themselves as merely defending and developing his ideas along what they took to be orthodox lines, others have sought to ‘reform’ his system, or to appropriate individual aspects and overturn others, or to offer consciously revisionary readings of his work. This makes it very hard to identify any body of doctrine common to members of this tradition, and a wide range of divergent philosophical views can be found among those who (despite this) can none the less claim to be Hegelians. There are both ‘internal’ and ‘external’ reasons for this: on one hand, Hegel’s position itself brings together many different tendencies (idealism and objectivism, historicism and absolutism, rationalism and empiricism, Christianity and humanism, classicism and modernism, a liberal view of civil society with an organicist view of the state); any balance between them is hermeneutically very unstable, enabling existing readings to be challenged and old orthodoxies to be overturned. On the other hand, the critical response to Hegel’s thought and the many attempts to undermine it have meant that Hegelians have continually needed to reconstruct his ideas and even to turn Hegel against himself, while each new intellectual development, such as Marxism, pragmatism, phenomenology or existential philosophy, has brought about some reassessment of his position. This feature of the Hegelian tradition has been heightened by the fact that Hegel’s work has had an impact at different times over a long period and in a wide range of countries, so that divergent intellectual, social and historical pressures have influenced its distinct appropriations. At the hermeneutic level, these appropriations have contributed greatly to keeping the philosophical understanding of Hegel alive and open-ended, so that our present-day conception of his thought cannot properly be separated from them. Moreover, because questions of Hegel interpretation have so often revolved around the main philosophical, political and religious issues of the nineteenth and twentieth centuries, Hegelianism has also had a significant impact on the development of modern Western thought in its own right. As a result of its complex evolution, Hegelianism is best understood historically, by showing how the changing representation of Hegel’s ideas have come about, shaped by the different critical concerns, sociopolitical conditions and intellectual movements that dominated his reception in different countries at different times. Initially, Hegel’s influence was naturally most strongly felt in Germany as a comprehensive, integrative philosophy that seemed to do justice to all realms of experience and promised to preserve the Christian heritage in a modern and progressive form within a speculative framework. However, this position was quickly challenged, both from other philosophical standpoints (such as F.W.J. Schelling’s ‘positive philosophy’ and F.A. Trendelenburg’s neo-Aristotelian empiricism), and by the celebrated generation of younger thinkers (the so-called ‘Young’ or ‘Left’ Hegelians, such as Ludwig Feuerbach, David Strauss, Bruno Bauer, Arnold Ruge and the early Karl Marx), who insisted that to discover what made Hegel a truly significant thinker (his dialectical method, his view of alienation, his ‘sublation’ of Christianity), this orthodoxy must be overturned. None the less, both among these radicals and in academic circles, Hegel’s influence was considerably weakened in Germany by the 1860s and 1870s, while by this time developments in Hegelian thought had begun to take place elsewhere. Hegel’s work was known outside Germany from the 1820s onwards, and Hegelian schools developed in northern Europe, Italy, France, Eastern Europe, America and (somewhat later) Britain, each with their own distinctive line of interpretation, but all fairly uncritical in their attempts to assimilate his ideas. However, in each of these countries challenges to the Hegelian position were quick to arise, partly because the influence of Hegel’s German critics soon spread abroad, and partly because of the growing impact of other philosophical positions (such as Neo-Kantianism, materialism and pragmatism). Nevertheless, Hegelianism outside Germany proved more durable in the face of these attacks, as new readings and approaches emerged to counter them, and ways were found to reinterpret Hegel’s work to show that it could accommodate these other positions, once the earlier accounts of Hegel’s metaphysics, political philosophy and philosophy of religion (in particular) were rejected as too crude. This pattern has continued into the twentieth century, as many of the movements that began by defining themselves against Hegel (such as Neo-Kantianism, Marxism, existentialism, pragmatism, post-structuralism and even ‘analytic’ philosophy) have then come to find unexpected common ground, giving a new impetus and depth to Hegelianism as it began to be assimilated within and influenced by these diverse approaches. Such efforts at rapprochement began in the early part of the century with Wilhelm Dilthey’s attempt to link Hegel with his own historicism, and although they were more ambivalent, this connection was reinforced in Italy by Benedetto Croce and Giovanni Gentile. The realignment continued in France in the 1930s, as Jean Wahl brought out the more existentialist themes in Hegel’s thought, followed in the 1940s by Alexander Kojève’s influential Marxist readings. Hegelianism has also had an impact on Western Marxism through the writings of the Hungarian Georg Lukács, and this influence has continued in the critical reinterpretations offered by members of the Frankfurt School, particularly Theodor W. Adorno, Max Horkheimer, Herbert Marcuse, Jürgen Habermas and others. More recently, most of the major schools of philosophical thought (from French post-structuralism to Anglo-American ‘analytic’ philosophy) have emphasized the need to take account of Hegel, and as a result Hegelian thought (both exegetical and constructive) is continually finding new directions.

Much of the history of occupational therapy is associated with the history of the National Health Service (NHS). As the nation celebrates the 50th anniversary of the founding of the NHS on 5 July 1948, it is fitting to reflect on the development of the profession over the past half century and how it has adapted to the many medical, technological, demographic and social changes. In 1948, the profession comprised a small band of mainly middle-class women, who worked under medical direction with long-stay patients in a hospital setting. In 1998, over 18,000 occupational therapists are state-registered. Having gained degree-entry status practitioners are increasingly self-directed and research-focused, and they work in a wide range of settings with all age-groups: a profession reflecting the ideals of the NHS to provide a service from ‘the cradle to the grave’.

Cinema, MD argues that within cinema there is a history of medicine—one version in the many different histories of medicine. How did filmmakers write a history of medicine? This book discusses how cinema depicts medicine, in all its glory and all its failures, and what can we learn from it. It offers an account of all the major films with medical themes. The book asks a number of critical questions, such as why scriptwriters and directors chose the subjects, the plots, the cast, and the images that they did. Films have covered a wide range of medical topics, depicting not only physicians, nurses, and other health-care personnel working in hospitals, clinics, and asylums but also epidemics, diseases and disabilities, mental illness, and addictions. Films have portrayed medical feats such as vaccinations and organ transplantations. Filmmakers also have tackled subjects such as death and dying, medical experimentation, and rare diseases, as well as documenting criticism of the medical status quo.

Abstract The Emamzadeh Yahya at Varamin, a tomb-shrine located south of Tehran, is well known for supplying global museums with iconic examples of Ilkhanid-period luster tilework. After providing a historiography of the site, including its plunder in the late nineteenth century, we explore its current (2018–20) “life” in order to illuminate the many ways that it can be accessed, used, perceived, and packaged by a wide range of local, national, and global stakeholders. Merging past and present history, art history and amateur anthropology, and the academic, personal, and popular voice, this article explores the Emamzadeh Yahya’s delicate and active existence between historical monument, museum object, sacred space, and cultural heritage.

The French-Argentine Paul Groussac embodied a wide range of writerly functions and cultural-political positions within the Argentine cultural field between the 1880s and the 1920s: writer, playwright, chronicler, traveler, literary, art, and music critic, historian, educator, editor, and director of the National Library during 44 years. This essay considers his place in the history of Argentine literature looking at two of the many ways in which he inscribed himself in it. The first takes up the production and reproduction of the ontological privilege of French identity as a form of legitimization for his public—and often polemic—interventions, through which he sought to establish scholarly-disciplinary practices, protocols, and conventions that would articulate an entire critical field around his own authority. The second proposes to think his alternatively weak and strong inscriptions in the literary tradition through his own narrative production: his fiction and dramaturgy, travelogues, and biographical sketches. In other words, this essay situates Groussac in an Argentine literary tradition (conceived as an organic and institutionally sanctioned textual corpus) he believed to have founded and established, a selfrepresentation that led Borges to say that Groussac saw himself as “a missionary of Voltaire among the mulattage.”

The article is devoted to the history of the creation and functioning of the Visegrad Group as a regional entity, which not only did not cease activities after achieving the goal of Atlantic and European integration, but also successfully develops it, already being a member of NATO and the European Union. Based on the use of a broad documentary framework, in particular, protocols and declarations as a result of meetings of various levels within the framework of the Visegrad Group, analyzed and identifies the concrete stages of its development and interaction with Ukraine in a wide range of components that form the essence of Euro-Atlantic integration. On concrete examples, it was illustrated that Ukraine has always been in the field of key interests of the Visegrad Four, received effective help and support from her side in a variety of forms. It is not just about practical issues of regional cooperation and security, but also about the many aspects of the value and civilization dimension. The participating countries of the Visegrad Group, having become the initiators of the “B4 + Ukraine” cooperation format, have never stood apart from the most important processes and transitional stages, through which Ukraine passed on its way to becoming and self-determination. The opinion is upheld, that the experience gained by the member countries of the Visegrad format is relevant and useful for Ukraine and today on the way of implementing its Euro-Atlantic integration aspirations. Despite the existing difficulties both within the European Union and between Ukraine and individual signatory countries of the Visegrad Declaration of 1991, cooperation with Poland, the Czech Republic, Slovakia and Hungary is the most effective communication platform for intensifying the broad dialogue between Ukraine and European Union.
