意大利和国际体育法及判例制裁的比例原则

研究意大利和国际体育法判例制裁的比例原则,首先需要了解意大利(以下简称国家)和国际体育规则。其次是根据意大利与国际体育法的判例如何与归责原则连接,以及解释(和执行)方式,尤其是关于足球与反兴奋剂规则。研究的主要目的是为了验证这一原则是否在规则中被编撰和认可(通过体育法庭得到解释和执行),评估这一原则是否应用于保护体育运动的完整性(确保它的正常运作),并应当平衡要遵守体育规则和保护运动员利益二者之间的关系。     

Science,Society and Trends in Science Education‐‐some Thoughts on the Development of Integrated Science in the Educational Systems of the World

Summaries

English

Before constructing a new curriculum for any level in integrated‐science education, it is very important to establish a basic philosophy of science teaching which reflects a symbiotic relationship between education and the socio‐economic development in a particular country of the world.

The curriculum structure of integrated‐science education should broaden the basis of curricular decision and should be designated to follow the expectations of the society in providing professional intellectual training so that education can make a significant contribution to the socio‐economic growth of the country. This basic assumption which established a link between cultural and socio‐economic growth, involves a diversification of the cultural trends of science education which must become appropriate to the economic and historical context of each country in a fast changing world of work.

Therefore, by critically removing outside influences in the transmission of scientific knowledge, there should be less uniformity in the context and methods of teaching, and considerable restructuring of education for each country should occur. Thus, considering the historical and geographical differences, a new order in international division of labour would come into being.

In such a hypothesis, a research‐oriented integrated curriculum in science education can play a central role (certainly a better one than in the traditional, discipline‐oriented scheme of science teaching) in obtaining an adequate interaction between scientific education and social problems; this is required for modern cultural and economic development of the world.     

A Graphical Method for Assessing the Identification of Linear Structural Equation Models

A graphical method is presented for assessing the state of identifiability of the parameters in a linear structural equation model based on the associated directed graph. We do not restrict attention to recursive models. In the recent literature, methods based on graphical models have been presented as a useful tool for assessing the state of identifiability of the parameters of the model. This article proposes the graphical counterpart of the rank condition of the matrix of structural coefficients, which allows for checking of the identifiability through a simple graphical rule. This approach can be used to develop algorithms.     

Lights,Camera, Action: Facilitating the Design and Production of Effective Instructional Videos

This paper outlines a rudimentary process intended to guide faculty in K-12 and higher education through the steps involved to produce video for their classes. The process comprises four steps: planning, development, delivery and reflection. Each step is infused with instructional design information intended to support the collaboration between instructional support staff and faculty to produce video that will be meaningful to students and support their success in a class. In outlining this approach, the paper also explores technological and pedagogical considerations related to each of these steps that can help faculty and staff determine how best to incorporate video into online classes. Finally, supported by research on best video practices and with examples from our own experiences as instructional designers and instructors, the paper outlines how these steps relate to four broad categories of video: introduce, model, explain/inform and feedback.     

The Pendulum: From Constrained Fall to the Concept of Potential

Kuhn underlined the relevance of Galileo’s gestalt switch in the interpretation of a swinging body from constrained fall to time metre. But the new interpretation did not eliminate the older one. The constrained fall, both in the motion of pendulums and along inclined planes, led Galileo to the law of free fall. Experimenting with physical pendulums and assuming the impossibility of perpetual motion Huygens obtained a law of conservation of vis viva at specific positions, beautifully commented by Mach. Daniel Bernoulli generalised Huygens results introducing the concept of potential and the related independence of the ‘work’ done from the trajectories (paths) followed: vis viva conservation at specific positions is now linked with the potential. Feynman’s modern way of teaching the subject shows striking similarities with Bernoulli’s approach. A number of animations and simulations can help to visualise and teach some of the pendulum’s interpretations related to what we now see as instances of energy conservation.     

Deductive teaching from computer science foundations

Various problems concerning the teaching of informatics arise from the foundations of computer science. Difficulties in terminology, in lesson definition, in the introduction to topics are examples of substantial and they are not psychological or expressive problems. The foundations are officially acknowledged as an open problem and they give rise to incomplete and mnemomic computer science learning. They do not allow the student to be aware of informatics themes. They subsequently inhibit programming, systems design, research and many other activities. This paper discusses the results of theoretical research on the foundations carried out at IBM. This facititates deductive teaching and improves students preparation on the basic contents and on all the other themes of computer science. The early lessons of a high-school course are outlined. © 1998 IFIP, published by Chapman & Hall Ltd     

e-university: a cross-case study in four Italian universities

This paper describes the aims, the methods, the stages and the results of the research project 'e-University. Information and communication technologies (ICTs) as a factor of change in Italian universities', undertaken between 2003 and 2006 by the Universities of Trento, Perugia and Sassari and the Catholic University of Milan.
The characteristics of the four institutions' subjects and objects of the investigation are analysed as case studies and then compared as a cross-case study in the light of the factors that we feel constitute the main areas of concern in the four institutions as to the implementation of ICTs in the teaching/learning process, ie, the characteristics of the governance strategic plan, the choices relating to technology and the choices related to pedagogy. The paper describes the collaborative effort characterising the community of researchers through the different stages of the research. It also analyses how the individual features of each university—relating to its history, the number of students, the range of faculties, the diffusion of e-learning, the driving factors for innovation, the institution's policies—have fostered a lively and fruitful discussion between different view points, thus engendering deeper reflections for each context.     

Biorthogonal wavelet trees in the classification of embedded signal classes for intelligent sensors using machine learning applications

The paper deals with a method of constructing orthonormal bases of coordinates which maximize, through redundant dictionaries (frames) of biorthogonal bases, a class separability index or distances among classes. The method proposes an algorithm which consists of biorthogonal expansions over two redundant dictionaries. Embedded classes are often present in multiclassification problems. It is shown how the biorthogonality of the expansion can really help to construct a coordinate system which characterizes the classes. The algorithm is created for training wavelet networks in order to provide an efficient coordinate system maximizing the Cross Entropy function between two complementary classes. Sine and cosine wavelet packets are basis functions of the network. Thanks to their packet structure, once selected the depth of the tree, an adaptive number of basis functions is automatically chosen. The algorithm is also able to carry out centering and dilation of the basis functions in an adaptive way. The algorithm works with a preliminary extracted feature through shrinkage technique in order to reduce the dimensionality of the problem. In particular, our attention is pointed out for time-frequency monitoring, detection and classification of transients in rail vehicle systems and the outlier problem. In the former case the goal is to distinguish transients as inrush current and no inrush current and a further distinction between the two complementary classes: dangerous inrush current and no dangerous inrush current. The proposed algorithm is used on line in order to recognize the dangerous transients in real time and thus shut-down the vehicle. The algorithm can also be used in a general application of the outlier detection. A similar structure is used in developed algorithms which are currently integrated in the inferential modeling platform of the unit responsible for Advanced Control and Simulation Solutions within ABB's (Asea Brown Boveri) industry division. It is shown how impressive and rapid performances are achieved with a limited number of wavelets and few iterations. Real applications using real measured data are included to illustrate and analyze the effectiveness of the proposed method.
