We propose a strategy for ranking scientific journals starting from a set of available quantitative indicators that represent imperfect measures of the unobservable ‘value’ of the journals of interest. After discretizing the available indicators, we estimate a latent class model for polytomous item response data and use the estimated model to classify each journal. We apply the proposed approac...

Otávio Bueno is Professor of Philosophy and Director of Graduate Studies at the University of Miami. His main areas of research are philosophy of science, philosophy of mathematics, and philosophy of logic, and he particularly enjoys exploring connections between them. He has published over 130 papers in journals and book chapters, including Noûs, Mind, Philosophy of Science, Synthese, Erkenntn...

Increasingly, mathematical, scientific and technical information is being distributed by electronic means, but having a high-quality paper printout remains important. We show here examples of techniques that are available for having both high-quality typesetting, in particular of mathematics, as well as useful navigation features and text extraction within electronic documents. For HTML, we sho...

The Wissenschaftliche Buchgesellschaft has kindly offered to publish a collection of my essays on the philosophy of mathematics, which have appeared in various journals. I accept this offer gladly, in particular since several of these essays are not easily accessible. The present volume can also serve as a temporary substitute for a comprehensive treatment of the philosophy of mathematics. This...

in recent years, mathematics is an essential aspect of all areas of daily life and the best predictor of being successful in economic situations of society. for many students, the mathematics accompanied with frustration, anxiety and negative attitudes towards mathematics. these students believe their anxiety have been derived from their math teachers, math misconception and weakness in math as...

Professor Bridges is not only an eminent mathematician, but also a distinguished intellectual with many interests outside mathematics; music and sport are two of his other passions. He has got a D.Sc. from Oxford University, and he is a Fellow of the Royal Society of New Zealand and a Corresponding Fellow of the Royal Society of Edinburgh. His research interests are very broad and include const...

Mathematics is an important subject whose applications were widely used in life. However, many students have difficulty learning mathematics, including elementary school students. This study aimed to examine the depth of Jean Piaget's cognitive development and Lev Vygotsky's sociocultural theory their implication for mathematics at age. a qualitative approach with literature method. Sources dat...

I have been working in Mathematics, Computational Mathematics, and Computer Science for more than five decades, facing research challenges and seeking new insights and novel methods. I was thrilled whenever I discovered new keys that opened challenging scientific locks, particularly when a single key opened a number of locks, as this was the case with my techniques of active operation/linear su...

Working in various areas of Mathematics, Computational Mathematics, and Computer Science for more than five decades, I introduced new insights and novel methods, solved a number of challenging research problems, revealed unexpected links among some seemingly distant subjects, and proposed new research directions and new areas of study. I was thrilled when in my research I was lucky to discover ...
