A brief history of quantum theory is given to illustrate the barriers to progress caused by preconceived ideas. The biases in my own thinking which I had to overcome to approach the right answer for the right reason are discussed. This is followed by a personal autobiography illustrating how I have led a life of serendipity with no real sense of purpose. Chance events have shaped my life. The algorithms for which I am best known are briefly discussed. Then highlights from the many applications of theory to excited states, bonding in ice, spin properties and magnetism, (e,2e) shake-up spectra, and organic reactions are mentioned. This wide range of applications is mostly due to accidental collaboration with colleagues who sought my help. My real interest was in developing methods which could address these problems.

During the 1370s Wyclif wrote to defend a monarchy which made extensive use of bishops and other clergy in the royal administration and yet was faced with aristocratic factions encouraged by bishops like Wykeham and Courtenay who espoused papal supremacy, if not out of conviction, at least as a very convenient weapon to support their independence against royal absolutism. At first sight Wyclifs attempts to define the right relationship between royal and episcopal, temporal and spiritual, power seem as confused as the contemporary political situation. His works contain such a wide range of theories from orthodox two swords dualism to a radical rejection of ecclesiastical authority well beyond that of Marsilius and Ockham that it seems as if his only interest was in collecting every anti-hierocratic idea available for use against the papacy. The purpose of this paper is to suggest that a much more coherent view of episcopal power can be detected beneath his tirades if it is appreciated that his continual demand for a great reform, a reformatio regni et ecclesiae, is inseparably linked to his understanding of the history of the Christian Church, and that in this way Wyclif anticipates Montesquieu in requiring a time factor as a necessary ingredient in constitutional arrangements.

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.

Adapted physical educators are spending much of their time and energy advocating for the right of all children and youth to a high quality of physical education service delivery and the elimination of attitudinal, aspirational, and architectural barriers experienced by handicapped persons. Prior to the 1960s, lawyers or legal advocates were the ones who would plead the cause for others. Since then, however, three types of advocates have evolved: citizen, professional, and consumer advocates. Adapted physical educators are professional advocates, but they must have an understanding of the other types of advocates. The purpose of this article is to acquaint adapted physical educators with the job function of advocacy, the history of advocacy, and the many roles advocates play.

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.

This article argues that problems of terminology also plague the study of the Athenian Empire, drawing attention to the many ancient Greek words that have been translated as ‘empire’. Arriving at the right terms to describe Athenian ‘imperialism’ would go hand in hand with the larger process of understanding other features of Athens' hegemony. For example, while the financial aspects of the Athenian Empire are heavily discussed, the cultural imperialism of the city-state still needs to be analysed more fully. Further study may well show that the major importance of the empire lies in its role as the transmitter of Hellenic culture during the period of Athens' dominance and not in its place as a decisive moment in the history of imperialism.

The ancient world is a paradigm for the memory scholar. Without an awareness that collective memories are not only different from individual memories (or even the sum thereof) but also highly constructed, ancient research will be fundamentally flawed. Many networks of memories are beautifully represented in the written and material remains of antiquity, and it is precisely the ways in which they are fashioned, distorted, preserved or erased through which we can learn about the historical process as such. Our evidence is deeply characterized by the fact that ancient ‘identity’ and ‘memory’ appear exceptionally strong. Responsible for this is a continuing desire to link the present to the remote past, which creates many contexts in which memories were constructed. The ancient historian therefore has the right tools with which to work: places and objects from the past, monuments and iconography, and textual narratives with a primary purpose to memorize and commemorate. This is paired with our desire to understand the ancient world through its own self-perception. With the opportunity of tapping into this world by way of oral history, personal testimonies are a desideratum in all respects. Memory of the past, however, is profoundly about ‘self-understanding’. This volume surveys and builds on the many insights we have gained from vibrant research in the field since Maurice Halbwachs’ and Jan Assmann’s seminal studies on the idea and definition of ‘cultural memory’. While focusing on specific themes all chapters address the concepts and expressions of memory, and their historical impact and utilization by groups and individuals at specific times and for specific reasons.

Abstract Introduction Neuroendoscopy plays an important role in minimally invasive neurosurgery. The authors reported an interesting case of a pediatric patient with multiple ventriculoperitoneal shunt (VPS) revision surgeries, presenting with VPS infection and with two crossed intraventricular floating catheter fragments, successfully removed through a neuroendoscopic navigated one-step procedure. A literature review regarding this exceedingly rare condition has also been discussed. Case Description An 11-year-old female patient with a history of congenital hydrocephalus was admitted to the emergency department with symptoms of intracranial hypertension, psychomotor agitation, and tetraparesis. She had a history of previous multiple VPS revisions. She had an urgent brain computed tomography scan that documented hydrocephalus; the VPS's intraventricular catheter tip was sited at the level of the right frontal horn. Two small floating catheter fragments, not connected to the VPS, were identified: the first close to the right lateral ventricle at the level of the right occipital horn, the second one between the right occipital horn and the third ventricle. First, she underwent an exteriorization of the distal catheter for VPS. Cerebrospinal fluid examination documented hyperproteinorrachia and a positive culture for Staphylococcus aureus. Then a navigated right transfrontal endoscopic approach to the right lateral ventricle was performed extending to the previous burr hole and achieving a wide range of working angle with a rigid 0-degree lens endoscope. Intermittent irrigation generating convective flow was performed such as to mobilize the catheters tip gently upward, to remove them by grasping. Finally, a whole VPS replacement has been performed. Conclusion Persistence of intraventricular floating catheter fragments can lead to subacute or chronic infections. Neuroendoscopic retrieval represents a safe and effective alternative to a more extensive and invasive surgical approach. However, the exact catheter tip identification, grasping, and removal can be difficult to achieve, due to the technical instrumentation characteristics and altered intraventricular anatomy in chronic congenital hydrocephalus. In our experience, endoscopic convective flow induction through saline irrigation can determine floating intraventricular catheter fragments movement aiming to their identification and subsequent successful endoscopic retrieval.

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.
