This dissertation examines the various ways in which Canadian historical researchers confronted the “Canada question,” namely the challenge of defining the basis of a unified national community. In doing so, it follows the scholarship and activities of a network of historians and intellectuals centred on the Canadian Historical Review, a quarterly publication founded in 1920. This study examines their scholarship with the aim of identifying not only the various solutions they posed to the problem, but also the philosophical undercurrents that informed their reasoning in the process. It also traces the rise of a rival network in the Revue d’histoire de l’Amérique française, a French-language historical publication founded in 1947 that by its very existence posed a significant challenge to the definition of the nation at the core of the Canadian Historical Review. This dissertation argues that the network bound together by the Review was engaged in a hegemonic project, one that sought to present a particular definition of Canada through a historical narrative that rested upon a liberal logic. Yet the greatest sustained challenge they faced in this endeavour emerged from Francophone historical scholars, who, although proposing vastly different Canadas to those imagined at the Canadian Historical Review, came under the sway of a number of liberal currents of thought as well. A detailed summary of the key traits of these liberal Canadas is found in the conclusion.

This thesis deals with the origins of the architectural forms as expressed in the Homeric Mycenaean citadel. The Genesis of the Mycenaean Citadel is a philosophical quest which reveals the poetic dimension of the Mycenaean architecture. The Introduction deals with general theories on the subject of space, which converge into one, forming the spinal idea of the thesis. The ‘process of individuation’, the process by which a person becomes ‘in-dividual’ that is a separate, indivisible unity or ‘whole’, is a process of transformation and renewal which at collective level takes place within the citadel. This is built on the archetype which expresses both the nature of the soul as a microcosm and of the divinely ordered Cosmos. The confrontation of the rational ‘ego’ with the unconscious is the process which brings us to the ‘self’, that organising center of the human psyche which is symbolised through the centre of the citadel. . Chapter I refers to ‘the Archetype of the Mycenaean citadel’. The Mycenaean citadel, which is built on a certain pattern of placement and orientation in relation to landscape formations, reproduces images which belong to the category of the ‘archetypal mother’. On the other hand, its adjustment to a central point with ‘high’ significance, recalls the archetypal image of Shiva-Shakti. The citadel realises the concept of a Kantian ‘One-all embracing space’; it is a cosmogonic symbol but also a philosophical one. Chapter II examines the column in its dual meaning, which is expressed in one structure; column and capital unite within their symbolism the conscious and unconscious contents of the human psyche and express the archetype of wholeness and goal of the individuation process. 33 Chapter III is a philosophical research into the ‘symbolism of the triangle’, the sacred Pythagorean symbol which expresses certain cosmological beliefs about the relation between human nature and the divinely ordered Cosmos. The triangular slab over the Lion Gate is a representation of the Dionysiac ‘palingenesia’, that is the continuity of One life, which was central to the Mycenaean religion. Chapter IV deals with the tripartite ‘megaron’. The circular hearth within the four-columned hall expresses the ‘quaternity of the One’, one of the oldest religious symbols of humanity. Zeus is revealed in the ‘fiery monadic unit-cubit’ as an all-embracing god next to goddess Hestia, symbolised by the circular hearth. The ‘megaron’ expresses the alchemical quaternity and the triad but also the psychological stages of development in the process towards wholeness. In the Conclusions it is emphasised that the Mycenaean citadel was created as if in a repetition of a cosmogony. It is a ‘mandala’, the universal image which is identified with God-image in man. Moreover it is built in order to be experienced by its citizen in the process of his psychological transformation towards the ‘self’, the divine element within the psyche which unites with the divinely ordered Cosmos

This paper deals with the interaction between fictitious capital and the neoliberal model of growth and distribution, inspired by the classical economic tradition. Our renewed interest in this literature has a close connection with the recent international crisis in the capitalist economy. However, this discussion takes as its point of departure the fact that standard economic theory teaches that financial capital, in this world of increasing globalization, leads to new investment opportunities which improve levels of growth, employment, income distribution, and equilibrium. Accordingly, it is said that such financial resources expand the welfare of people and countries worldwide. Here we examine some illusions and paradoxes of such a paradigm. We show some theoretical and empirical consequences of this vision, which are quite different and have harmful constraints.

The objective of the following article is to give the reader a perspective on the events of 1956 in Hungary – known commonly as the 1956 Hungarian Uprising or Revolution (or as it is sometimes called in Hungary: the 1956 Revolution and Freedom Fight) – from the point of view of counterinsurgency theory. The author intends to show that the current theory has many problems and shortcomings when it comes to the analysis of the events of 1956 because of the unique set of circumstances which prevailed at that time.

The aim of this dissertation is to present the sequence of events which brought the scientific community of the early 20th century to conceive an expanding Universe born from a single origin. Among the facts here reported, some are well-known, some others instead are little-known backstories, not so easy neither to obtain nor to trust. Indeed, several matters shown in this thesis, now as then, create a battleground among scientists. Amid the numerous personalities whose contributions are discussed in this work, the main protagonist is surely Georges Lemaître, who managed to combine – without overlapping – his being both a priest and a scientist. The first chapter is dedicated to his biography, from his childhood in Belgium, to his early adulthood between England and the USA, to his success in the scientific community. The second and the third chapter explain how the race to the understanding of a Universe which not only expands, but also originated from a singularity, developed. The Belgian priest’s discoveries, as shown, were challenged by other important scientists, who, in several cases, Lemaître had a friendly relationship with. As a consequence, the fourth and final chapter deals with the multiple relations that the priest managed to build, thanks to his politeness and kindness. Moreover, it is also covered Lemaître’s personal connection with the Church and religion, without forgetting the personalities that influenced him – above all, Saint Thomas Aquinas. As a conclusion to this thesis, two appendices gather not only a summary of Lemaître’s works which are not already described in the chapters, but also the biographies of all the characters presented in this dissertation.

Shallow-water tropical reefs and the deep sea represent the two most diverse marine environments. Understanding the origin and diversification of this biodiversity is a major quest in ecology and evolution. The most prominent and well-supported explanation, articulated since the first explorations of the deep sea, holds that benthic marine fauna originated in shallow, onshore environments, and diversified into deeper waters. In contrast, evidence that groups of marine organisms originated in the deep sea is limited, and the possibility that deep-water taxa have contributed to the formation of shallow-water communities remains untested with phylogenetic methods. Here we show that stylasterid corals (Cnidaria: Hydrozoa: Stylasteridae)-the second most diverse group of hard corals-originated and diversified extensively in the deep sea, and subsequently invaded shallow waters. Our phylogenetic results show that deep-water stylasterid corals have invaded the shallow-water tropics three times, with one additional invasion of the shallow-water temperate zone. Our results also show that anti-predatory innovations arose in the deep sea, but were not involved in the shallow-water invasions. These findings are the first robust evidence that an important group of tropical shallow-water marine animals evolved from deep-water ancestors.

Background: It has been speculated that the biostimulatory effect of Low Level Laser Therapy could cause undesirable enhancement of tumor growth in neoplastic diseases. The aim of the present study is to analyze the behavior of melanoma cells (B16F10) in vitro and the in vivo development of melanoma in mice after laser irradiation. Methods: We performed a controlled in vitro study on B16F10 melanoma cells to investigate cell viability and cell cycle changes by the Tripan Blue, MTT and cell quest histogram tests at 24, 48 and 72 h post irradiation. The in vivo mouse model (male Balb C, n = 21) of melanoma was used to analyze tumor volume and histological characteristics. Laser irradiation was performed three times (once a day for three consecutive days) with a 660 nm 50 mW CW laser, beam spot size 2 mm(2), irradiance 2.5 W/cm(2) and irradiation times of 60s (dose 150 J/cm(2)) and 420s (dose 1050 J/cm(2)) respectively. Results: There were no statistically significant differences between the in vitro groups, except for an increase in the hypodiploid melanoma cells (8.48 +/- 1.40% and 4.26 +/- 0.60%) at 72 h postirradiation. This cancer-protective effect was not reproduced in the in vivo experiment where outcome measures for the 150 J/cm(2) dose group were not significantly different from controls. For the 1050 J/cm(2) dose group, there were significant increases in tumor volume, blood vessels and cell abnormalities compared to the other groups. Conclusion: LLLT Irradiation should be avoided over melanomas as the combination of high irradiance (2.5 W/cm(2)) and high dose (1050 J/cm(2)) significantly increases melanoma tumor growth in vivo.

With the relentless quest for improved performance driving ever tighter tolerances for manufacturing, machine tools are sometimes unable to meet the desired requirements. One option to improve the tolerances of machine tools is to compensate for their errors. Among all possible sources of machine tool error, thermally induced errors are, in general for newer machines, the most important. The present work demonstrates the evaluation and modelling of the behaviour of the thermal errors of a CNC cylindrical grinding machine during its warm-up period.
