Our historical study of Canada’s main research university illuminates the overlooked influence of national identities and interests as forces shaping the institutionalization of technology transfer. Through the use of archival sources we trace the rise and influence of Canadian technological nationalism—a response to Canada’s perceived dependency on the United States’ science and technology. Technological nationalism provided a symbol for producing a shared understanding of the desirability and appropriateness of technology transfer that legitimated the commercial activities of university scientists.  相似文献

Plasterwork, a very typical element of Islamic art, comprises highly artistic decorative elements on wall, arches, and vaults. Due to their gypsum composition, such elements are easily weathered, primarily because of low mechanical strength and slight solubility in water. This work has studied the traditional Islamic plasterwork in the halls and patios of the Mudéjar Palace (13–16th centuries) in the Real Alcázar of Seville. This palace complex was declared a World Heritage Site by UNESCO in 1987. The analysis of its porosity and shore C surface hardness has allowed determination of the mathematical correlation between them. Consequently, future evaluations can merely measure the hardness (a non-destructive test) to estimate the plasterwork's porosity (which reveals its mechanical strength and its degree of weathering). These elements must be maintained in order to prevent the spread of pathologies. In addition to requiring an in-depth knowledge of its materials, application techniques, and properties, to do so also demands simple techniques for regular assessments and criteria to prioritize interventions if they become necessary.  相似文献

In this work, in order to model network traffic processes, an efficient multifractal model is proposed based on fewer parameters than other models present in the literature, called 2PEMV. The 2PEMV model (2-Parameter Exponential Modeling for Multipliers’ Variance) is based on a multiplicative cascade in the wavelet domain capable of synthesizing communication network traffic traces which present characteristics such as self-similarity and wide Multifractal Spectrum Width (MSW). For such a purpose, in the 2PEMV model, the energy decay of the wavelet coefficients is captured by means of an exponential modeling for the multipliers’ variance along the cascade scales. The performance of the 2PEMV model to represent the network traffic characteristics is evaluated in comparison to other models present in the literature through simulations that are carried out using real communication network traffic traces.  相似文献

The media industry is undergoing comprehensive change due to the shifting audience and consumption patterns fostered by the diffusion of the Internet. This article describes how these changes shape established practices of video production and redefine the cultural categories of video and broadcasting. Drawing on an empirical case study of the practices within the British Broadcasting Corporation (BBC), the we show the production of video content to be increasingly unbundled and broken down into several smaller processes, which make it possible to manage and recompose in a variety of ways that transcend established institutional divisions and cultural perceptions. At the same time and as a means of accommodating multiplatform content delivery, video distribution is acquiring flexible and mutating formats that further destabilize the perception of video as a self-sufficient cultural form. In this context, video metadata rises to be an important coordinative medium that provides the cognitive resources for identifying and managing video content within and across particular settings and the link through which the operations of media organizations become entangled with the technical landscape of the Internet.  相似文献

Olympic sport is a double-edged sword. It has the potential to bring nations together and to transmit values, but it can also demonstrate international political tensions and conflicting national structural characteristics. As part of the International Olympic Movement from the very beginning, Hungary is one of the few nations to have taken part in the (Summer) Olympic Games in London for the third time. The Olympic presence of Hungary has been almost continuous in spite of the significant transformations of its state ideology, sport structures and political background. In 1908, within the framework of the Austro-Hungarian Monarchy, the Hungarian Kingdom endeavoured to demonstrate its autonomy and courage with its memorable Olympic successes in London. A People's Republic was being formed in Hungary at the time of the second London Olympic Games in 1948. The socialist ideology and the self-display of socialist–communist ambitions characterised the preparation and the participation of the Hungarian athletes. Hungary is celebrating the year of its third London Games with a democratic system in the background, built up from 1989, and a new Constitution adopted in 2011. Furthermore, the Hungarian Sport Act was renewed in 2012, due to which the Hungarian Olympic Committee has gained increased power, which might provide new ways of solving the financial problems within Hungarian elite sport.  相似文献

The referee is an essential part of the codified form of Association Football that we know today. Nevertheless, this has not always been the case; whilst a referee, in some form, has been a requirement since codification in order for football matches to occur, referees have not always been central in the thought process of rule makers and those developing the game. This essay explores the evolution of the referee within Association Football and, more specifically, the training, support and assessment practices that referees have received since the codification of Association Football in 1863. Therefore, this essay focuses on debates and input from governing bodies, such as the Football Association, FIFA and the Referees Associations specifically related to referees and their training, support and assessment as the association code of football continued to evolve.  相似文献
