Isolated Lepton Production at Colliders

The production of isolated leptons with high transverse momentum in high energy e-e, p-p or e-p collisions is reviewed. The leptons are produced either through boson splitting or by boson-boson collision and yield experimentally simple and spectacular topologies which can be exploited to validate the Standard Model or to search for new phenomena.Comment: 50 page

Creativity in the Philosophy Class. Concrete Research

The issue of creativity among teachers and pupils in terms of the dialogical praxis represented a real challenge concerning the research that we have done in high school classes in which philosophy is being taught. We have come to the conclusion that there is a direct linking between the diversity of the dialogical forms which pupils and teachers use and the forms of expression of creativity that are used during philosophy classes. Philosophical themes seem more attractive and interesting if the working methods in classes are modified and if pupils have to evaluate critically their own knowledge. (DIPF/Orig.)Die Kreativität der Schüler und Lehrer in der Methode dialogischer Praxis während des Philosophieunterrichts von Oberschulklassen stellte im Kontext dieser repräsentativen Untersuchung eine Herausforderung dar. Unsere Feststellungen zeigen die direkte Verknüpfung zwischen der Vielfalt dialogischer Formen, welche die Schüler und Lehrer übernommen haben und den Formen und Ebenen der Kreativität der Schüler während des Philosophieunterrichts. Philosophische Themen gewinnen an Attraktivität, wenn die Arbeitsmethoden in der Klasse dahin gehend geändert werden, dass die Schüler gefordert sind, ihre Kenntnisse kritisch zu bewerten und ihre Position aus einem philosphischen Blickwinkel zu überprüfen.

The Role of Innovation for the Economic Growth and Development of the States. The Case of the Emerging Countries

At the beginning of the XXIst century, the importance of innovation is brought in light mainly due to the huge differences that exist between the living standard of the richest and of the poorest nations, differences that could be partly explained through the fact that the most advanced countries pay a greater attention to the intensive side of economic activity. The purpose of this paper is to determine the way in which innovation actually influences the economic growth and the prosperity of a country. Being known that between the stock of human and social capital, on one side, and the innovation, on the other side, there is a strong positive correlation, we will try to identify the possibilities that developing economies have to foster the innovation. The relationship between human capital and innovation will be analyzed in order to see how it could be optimized so that to obtain the best results on both micro and macroeconomic level. The example of China, whose fast development astonished the world, will serve as a model in reaching out our purposes.

THE MULTINATIONAL COMPANIES AND THE LOW-COST MARKETS OF SOUTH-EAST ASIA

In order to be considered a low-cost market, the cost advantage of one or more factors of production offered by a state – generally, a developing one – must be exploited by the multinational firms. Therefore, we may speak about these markets only after 19multinational company, low-cost market, foreign direct investments, developing state, location advantages

Learning to Convolve: A Generalized Weight-Tying Approach

Recent work (Cohen & Welling, 2016) has shown that generalizations of convolutions, based on group theory, provide powerful inductive biases for learning. In these generalizations, filters are not only translated but can also be rotated, flipped, etc. However, coming up with exact models of how to rotate a 3 x 3 filter on a square pixel-grid is difficult. In this paper, we learn how to transform filters for use in the group convolution, focussing on roto-translation. For this, we learn a filter basis and all rotated versions of that filter basis. Filters are then encoded by a set of rotation invariant coefficients. To rotate a filter, we switch the basis. We demonstrate we can produce feature maps with low sensitivity to input rotations, while achieving high performance on MNIST and CIFAR-10.Comment: Accepted to ICML 201
