To reveal the theories and practices that linked education to the development within the cities of Boston and Buenos Aires, and in turn to the development of US and Argentina nationalism, “Cosmopolitan Imperialism” centers on two education reformers, Horace Mann (1776-1859) and Domingo Faustino Sarmiento (1811-1888). Mann and Sarmiento formed part of a supra-national community where liberal intellectual elites created a republic of letters, or perhaps better said, a republic of schools. As different versions of education branched out from a common Atlantic origin during the nineteenth century, Mann and Sarmiento searched for those ideas that better fit their national projects, a local project that started in the cities and moved to the interior parts of the country. In Boston and Buenos Aires, modern nationalism intertwined with imperial projects. This dissertation thus analyzes nationalism and reform in the nineteenth-century as an imperial project led by cosmopolitan intellectual elites. While we might expect to find Mann and Sarmiento’s ideas on education to be centered on their national experiences, looking to Europe for inspiration, this dissertation shows that it was quite the opposite. Educational ideas developed within an interconnected network and traveled within the North-South axis connecting Boston with Buenos Aires. This framework moves the focus from the interchange of ideas between America and Europe and places it within the American continent. At the same time, it allows us to consider Latin American and the US as both creators and recipients of educational ideas. There is a traditional way of talking about nationalism and reform in the nineteenth-century, especially in terms of education and educational policies. It is common to imagine that in the US, and even more certainly in Latin America, educated elites looked to the so-called West for inspiration. The argument is that they ended up adapting foreign models to their local and internal contexts. This dissertation challenges that idea and shows that different versions of education developed from a shared Atlantic milieu in which reformers in certain cities saw themselves as part of the same cosmopolitan empires.

This article presents a compilation of female artists who carried out their sculptural work during the twentieth century. With a brief presentation of each of them I want to implement visibility and the importance of incorporating their works to the collective imagery in order to be added to Spanish contemporary arts history. Some of them have public monuments of great popular recognition but their names have not been mentioned yet. Some others have “minor” works but they were relevant teachers to other artists. A few of them have extensive monographs about their life and their works. While others have almost gone unnoticed, but the proof of their professional career’s existence seems fundamental to us and they must be incorporated to history either through text books, university research works, ideally achieving a supported research project, to provide them the visibility their works and their vital trajectories deserve.

There is a growing literature which documents the importance of early life environment for outcomes across the life cycle. Research, including studies based on Irish data, demonstrates that those who experience better childhood conditions go on to be wealthier and healthier adults. Therefore, inequalities at birth and in childhood shape inequality in wellbeing in later life, and the historical evolution of the mortality and morbidity of children born in Ireland is important for understanding the current status of the Irish population. In this paper, I describe these patterns by reviewing the existing literature on infant health in Ireland over the course of the 20th century. Up to the 1950s, infant mortality in Ireland (both North and South) was substantially higher than in other developed countries, with a large penalty for those born in urban areas. The subsequent reduction in this penalty, and the sustained decline in infant death rates, occurred later than would be expected from the experience in other contexts. Using records from the Rotunda Lying-in Hospital in Dublin, I discuss sources of disparities in stillbirth in the early 1900s. Despite impressive improvements in death rates since that time, a comparison with those born at the end of the century reveals that Irish children continue to be born unequal. Evidence from studies which track people across the life course, for example research on the returns to birthweight, suggests that the economic cost of this early life inequality is substantial.

Identifying 20th-century periodic coastal surge variation is strategic for the 21st-century coastal surge estimates, as surge periodicities may amplify/reduce future MSL enhanced surge forecasts. Extreme coastal surge data from Belfast Harbour (UK) tide gauges are available for 1901–2010 and provide the potential for decadal-plus periodic coastal surge analysis. Annual extreme surge-elevation distributions (sampled every 10-min) are analysed using PCA and cluster analysis to decompose variation within- and between-years to assess similarity of years in terms of Surge Climate Types, and to establish significance of any transitions in Type occurrence over time using non-parametric Markov analysis. Annual extreme surge variation is shown to be periodically organised across the 20th century. Extreme surge magnitude and distribution show a number of significant cyclonic induced multi-annual (2, 3, 5 & 6 years) cycles, as well as dominant multi-decadal (15–25 years) cycles of variation superimposed on an 80 year fluctuation in atmospheric–oceanic variation across the North Atlantic (relative to NAO/AMO interaction). The top 30 extreme surge events show some relationship with NAO per se, given that 80% are associated with westerly dominant atmospheric flows (+ NAO), but there are 20% of the events associated with blocking air massess (− NAO). Although 20% of the top 30 ranked positive surges occurred within the last twenty years, there is no unequivocal evidence of recent acceleration in extreme surge magnitude related to other than the scale of natural periodic variation.

In the last decade of the 19th and first decades of the 20th century there was a movement of capital and engineers from the central and northern Europe to the countries of southern Europe and other continents. Large companies sought to obtain concessions and establish branches in Portugal, favouring the circulation of technical knowledge and transfer of technology for Portuguese industry. Among the various examples of the representatives of foreign companies in Portugal we find Jayme da Costa Ltd. established in 1916 in Lisbon, which was a branch of the Swedish company ASEA, as well as STAAL, ATLAS DIESEL (Sweden), Landis & GYR (Switzerland), Electro Helios, etc.. Another example is EFACEC a company founded in 1948 in Porto, that was a partnership between the Portuguese company CUF – Companhia União Fabril, and ACEC – Ateliers de Constructions Électriques de Charleroi and a small entreprise Electro-Moderna Ldª. This enterprise started the industrial production of electric motors and transformers, and later on acquired a substantial share of the national production of electrical equipment. Using Estatística das Instalações Elétricas em Portugal (Statistics on Electrical Installations in Portugal) from 1928 until 1950 we can identify the foreign enterprises acting in the Portuguese market: Siemens, B.B.C, ASEA, Oerlikon, etc. We can also establish a relationship between the development of the electric network and the growth of production and consumption of electricity in the principal urban centres. Finally we see how foreign firms were a stimulus to the creation of national enterprises, especially those of small scale, in Portugal.

The job of a historian is to understand what happened in the past, resorting in many cases to written documents as a firsthand source of information. Text, however, does not amount to the only source of knowledge. Pictorial representations, in fact, have also accompanied the main events of the historical timeline. In particular, the opportunity of visually representing circumstances has bloomed since the invention of photography, with the possibility of capturing in real-time the occurrence of a specific events. Thanks to the widespread use of digital technologies (e.g. smartphones and digital cameras), networking capabilities and consequent availability of multimedia content, the academic and industrial research communities have developed artificial intelligence (AI) paradigms with the aim of inferring, transferring and creating new layers of information from images, videos, etc. Now, while AI communities are devoting much of their attention to analyze digital images, from an historical research standpoint more interesting results may be obtained analyzing analog images representing the pre-digital era. Within the aforementioned scenario, the aim of this work is to analyze a collection of analog documentary photographs, building upon state-of-the-art deep learning techniques. In particular, the analysis carried out in this thesis aims at producing two following results: (a) produce the date of an image, and, (b) recognizing its background socio-cultural context,as defined by a group of historical-sociological researchers. Given these premises, the contribution of this work amounts to: (i) the introduction of an historical dataset including images of “Family Album” among all the twentieth century, (ii) the introduction of a new classification task regarding the identification of the socio-cultural context of an image, (iii) the exploitation of different deep learning architectures to perform the image dating and the image socio-cultural context classification.

The most recent account of Bueckeburgichnus maximus Kuhn 1958, a distinctive theropod dinosaur track from the Lower Cretaceous of Germany, is shown to be based on a referred specimen mistakenly identified as the holotype and the correct name of this taxon is deemed to be Megalosauripus maximus (Kuhn 1958). This minor revision has important consequences for nomenclature of the many European, Asian, North American and Australian dinosaur tracks attributed to megalosaurian theropods. Many of those tracks were named Megalosauripus, but that name has a confusing multiplicity of meanings and it should be restricted to the highly characteristic dinosaur track formerly identified as Bueckeburgichnus. Other tracks named "Megalosauripus”; (in its several other senses) will require new nomenclature, despite their extensive and repeated revision since 1996. It is recommended that future revision should adopt conventions of the International Code of Zoological Nomenclature. Although previous revisions expressed an intention to adhere to those conventions, these were not put into practice, with the unfortunate result of multiplying the problems that surround the nomenclature of megalosaur tracks. Introduction of the name Megalosauripus maximus (Kuhn 1958) eliminates those burgeoning problems and permits the introduction of new and objective nomenclature for presumed megalosaur tracks.

More than a decade ago, 'plasticity' suddenly became a 'fashionable' topic with overemphasized implications for regenerative medicine. The concept of 'plasticity' is supported by old transplantation work, at least for embryonic cells, and metaplasia is a classic example of plasticity observed in patients. Nevertheless, the publication of a series of papers showing rare conversion of a given cell type into another unrelated cell raised the possibility of using any unaffected tissue to create at will new cells to replace a different failing tissue or organ. This resulted in disingenuous interpretations and a reason not to fund anymore research on embryonic stem cells (ESc). Moreover, many papers on plasticity were difficult to reproduce and thus questioned; raising issues about plasticity as a technical artefact or a consequence of rare spontaneous cells fusion. More recently, reprogramming adult differentiated cells to a pluripotent state (iPS) became possible, and later, one type of differentiated cell could be directly reprogrammed into another (e.g. fibroblasts into neurons) without reverting to pluripotency. Although the latter results from different and more robust experimental protocols, these phenomena also exemplify 'plasticity'. In this review, we want to place 'plasticity' in a historical perspective still taking into account ethical and political implications.

Hemoglobin concentration is one of the principal factors of aerobic power and, consequently, of performance in many types of physical activities. The use of recombinant human erythropoietin is, therefore, particularly powerful for improving the physical performances of patients, and, more generally, improving their quality of life. This article discusses procedures for monitoring recombinant erythropoietin and its analogues in doping for athletic performance.

The Spanish automobile industry had a late start. Although the country proved capable of short production runs of high-quality vehicles during the first third of the century it never managed to build up its own industry, unlike Great Britain, France, or Italy. What then, were the critical shortcomings that prevented the establishment of large Spanish motor manufacturers? Put another way, why did all of the companies set up during the first half-century fail to survive? This paper attempts to shed some light on these questions, employing a wide-ranging analysis of both internal and external factors affecting the industry. A feeble internal market, lack of resources and production factors are usually adduced as reasons, as are Spain's general economic backwardness and the role played by the public authorities. However, this paper mainly focuses on the internal factors concerning company strategy and organisation. A comparison with the Italian case helps put the traditional arguments in proper perspective and highlights those covering business strategies. Finally, we argue that a broad range of factors needs to be analysed to fully understand why Spain failed to establish a motor industry.
