Innovation, Ethics and our Common Futures: A Collaborative Philosophy

The important yet contradictory role of innovation in society calls for a philosophy of innovation. Critically exploring innovation in relation to values, the economy and social change, Rafael Ziegler proposes a collaborative theory and practice of innovation that aims to liberate possibilities for our common futures. Following cues from the arts and drawing on the innovation literature across the social sciences, this book exposes pro-innovation bias and the gospel of disruptive change. Not only entrepreneurs but also civic networks and tinkerers are discussed as sources of innovation, and social change as a balancing act of innovation, exnovation and restoration. The discussion of capabilitarian, communitarian, liberal, republican and socialist ideas of justice and innovation leads Ziegler to a transformative proposal: ‘enough innovation’ based on enough for all and with respect for all. This is a thought-provoking read for scholars working on sustainability-transformation, democratic, responsible and social innovation, and philosophy of economics.

Migration and Environmental Change in Morocco: In search for Linkages Between Migration Aspirations and (Perceived) Environmental Changes (IMISCOE Research Series)

This open access book studies the migration aspirations and trajectories of people living in two regions in Morocco that are highly affected by environmental change or emigration, namely Tangier and Tinghir, as well as the migration trajectories of immigrants coming from these regions currently living in Belgium. This book departs from the development of a new theoretical framework on the relationship between environmental changes and migration that can be applied to the Moroccan case. Qualitative research conducted in both countries demonstrate how the interplay between migration and environmental factors is not as straightforward as it seems, due to its wider social, political, economic, demographic and environmental context. Findings show how existing cultures of migration, remittances, views on nature and discourses on climate change create distinct abilities, capacities and aspirations to migrate due to environmental changes. The results illustrate how migration and environmental factors evolve gradually and mutually influence each other. In doing so, this book offers new insights in the ways migration can be seen as an adaptation strategy to deal with environmental change in Morocco.

The Whys of Subnuclear Physics (The Subnuclear Series #15)

From 23 July to 10 August 1977 a group of 125 physicists from 72 laboratories of 20 countries met in Erice to attend the 15th Course of the International School of Subnuclear Physics. The countries represented at the School were: Belgium, Bulgaria, Denmark, Federal Republic of Germany, Finland, France, Hungary, Ireland, Israel, Italy, Japan, the Netherlands, Norway, Poland, Sweden, Switzerland, the United Kingdom, the United States of America and Venezuela. The School was sponsored by the Italian Ministry of Public Education (MPI), the Italian Ministry of Scientific and Technologi­ cal Research (MRST) , the North Atlantic Treaty Organization (NATO), the Regional Sicilian Government (ERS) and the Heizmann Institute of Science. The School was very exciting due to the impressive number of frontier problems which were discussed. Being the 15th year of the School, it was decided to review all outstanding "Whys". At various stages of my work I have enjoyed the collaboration of many friends whose contributions have been extremely important for the School and are highly appreciated. I would like to thank Dr.A. Gabriele, Ms.S. McGarry, Mr. and Mrs. S. Newman, Ms.P. Savalli and Ms.M. Zaini for the general scientific and administrative work. Finally, I would like to thank most warmly all those ~n Erice, Bologna and Geneva who helped me on so many occasions and to whom I feel very much indebted.

The New Aspects of Subnuclear Physics (The Subnuclear Series)

In August 1978 a group of 80 physicists from 51 laboratories of 15 countries met in Erice to attend the 16th Course of the International School of Subnuclear Physics. The countries represented at the School were: Austria, Denmark, Federal Republic of Germany, Finland, France, Israel, Italy, the Netherlands, Sweden, Switzerland, South Africa, Turkey, the United Kingdom, The United States of America, and Yugoslavia. The School was sponsored by the Italian Ministry of Public Education (MPI) , the Italian Ministry of Scientific and Technological Research (MRSI) , the North Atlantic Treaty Organization (NATO), the Sicilian Regional Government, and the Weizmann Institute of Science. As usual, the Course was devoted to a review of the most out­ standing problems and results in Subnuclear Physics, with particular emphasis on the new aspects; there were mainly two: supersymmetry and electroweak interactions. In his famous lecture at Erice in 1967, Sid Coleman reviewed "All possible symmetries of the S matrix. " All but one, namely that which tells you: if you have a fermion you must have a boson. This is super symmetry , and this produces the superspace, i. e. an entity which has not only the Einstein-"bosonic" coordinates, but also "fermionic" coordinates. From superspace we get supergravity; and this means that one day we should be able to detect not only the graviton (with spin 2) but also the gravitino (spin 3/2). If we add "flavour", "colour", and "family" as other intrinsic degrees of freedom, we get extended supergravity.

Understanding the Fundamental Constituents of Matter (The Subnuclear Series #14)

During July and August of 1976 a group of 90 physicists from 56 laboratories in 21 countries met in Erice for the 14th Course of the International School of Subnuclear Physics. The countries represented were Argentina, Australia, Austria, Belgium, Denmark, the Federal Republic of Germany, France, the German Democratic Republic, Greece, Israel, Italy, Japan, Mexico, Nigeria, Norway, Sweden, the United Kingdom, the United States of America, Vietnam, and Yugoslavia. The School was sponsored by the Italian Ministry of Public Education (MPI), the Italian Ministry of Scientific and Technological Research (MRST), the North Atlantic Treaty Organi­ zation (NATO), the Regional Sicilian Government (ERS), and the Weizmann Institute of Science. The program of the School was mainly devoted to the elucida­ tion and discussion of the progress achieved in the theoretical and experimental understanding of the fundamental constituents of matter. On the theoretical front we had a series of remarkable lecturers (C. N. Yang, S. Weinberg, G. C. Wick) attempting a description of finite size particles. Another group of lecturers covered such topics as the understanding of the new particles (H. J. Lipkin), whether or not jets really exist (E. Lillethun), and the unexpected A-dependence of massive dileptons produced in high-energy proton-­ nucleus collisions (J. W. Cronin). Two other outstanding questions were covered by E. Leader and G. Preparata respectively: whether strong interactions are still within the Regge framework, and if it is really possible to master strong interactions. A. J. S.

New Phenomena in Subnuclear Physics: Part A (The Subnuclear Series #13)

In July 1975 a group of 122 physicists from 68 laboratories of 27 countries met in Erice to attend the 13th Course of the International School of Subnuc1ear Physics. The countries represented at the School were: Australia, Austria, Belgium, Brazil, Canada, Chile, Denmark, France, Germany, Greece, India, Iran, Israel, Italy, Japan, Mexico, The Netherlands, Norway, Poland, Portugal, Spain, Sweden, Switzerland, Turkey, The United Kingdom, The United States of America and Yugoslavia. The School was sponsored by the Italian Ministry of Public Education (MPI), the Italian Ministry of Scientific and Technolog­ ical Research (MRST) , the North Atlantic Treaty Organization (NATO), the Regional Sicilian Government (ERS) and the Weizmann Institute of Science. The School was one of the most exciting, due to the impressive number of discoveries made not only in the field of the new par­ ticles by the MIT-BNL (reported by S. C. C. Ting) and by the SLAC­ SPEAR (reported by M. Breidenbach) Groups, but also in the field of high energy neutrino interactions where Carlo Rubbia observes ~­ pairs, together with bumps in the total energy of the hadronic system at Wh~4 GeV and a discontinuity in the at Ev~50 GeV plus a bump at Wmin~4 GeV; all these phenomena being possibly connected. To this remarkable amount of new and exciting results it has to be added the great discovery of DORIS (reported by B. Wiik) on the first example of a new particle Pc: the highlight of the Course.

Transformation of the natural environment in Western Sørkapp Land (SpringerBriefs in Geography)

This revised edition describes the transformation of the environment and landscape of Western Sørkapp Land based on research data collected by Jagiellonian University scientific expeditions in the period 1980–1986 and in 2008. It also outlines potential directions of the transformation of Western Sørkapp Land.Western Sørkapp Land has been experiencing dramatic natural changes such as glacial recession, coastline retreat, emergence of new landforms and Quaternary deposits, as well as changes in the water drainage and network due to global warming. Western Sørkapp Land is a very remote and diverse region, which is representative of the European Arctic. The establishment of South Spitsbergen National Park has led to a regeneration of the local reindeer herd, which has caused overgrazing of the local tundra resulting in altered plant communities and soil erosion. They have also destroyed numerous bird nests. The transformation of Western Sørkapp Land is set to continue.

Development Discourse and Global History: From colonialism to the sustainable development goals (Routledge Explorations in Development Studies)

The manner in which people have been talking and writing about ‘development’ and the rules according to which they have done so have evolved over time. Development Discourse and Global History uses the archaeological and genealogical methods of Michel Foucault to trace the origins of development discourse back to late colonialism and notes the significant discontinuities that led to the establishment of a new discourse and its accompanying industry. This book goes on to describe the contestations, appropriations and transformations of the concept. It shows how some of the trends in development discourse since the crisis of the 1980s – the emphasis on participation and ownership, sustainable development and free markets – are incompatible with the original rules and thus lead to serious contradictions. The Eurocentric, authoritarian and depoliticizing elements in development discourse are uncovered, whilst still recognizing its progressive appropriations. The author concludes by analysing the old and new features of development discourse which can be found in the debate on Sustainable Development Goals and discussing the contribution of discourse analysis to development studies. This book is aimed at researchers and students in development studies, global history and discourse analysis as well as an interdisciplinary audience from international relations, political science, sociology, geography, anthropology, language and literary studies.

Difference Methods for Initial-Boundary-Value Problems and Flow Around Bodies

Since the appearance of computers, numerical methods for discontinuous solutions of quasi-linear hyperbolic systems of partial differential equations have been among the most important research subjects in numerical analysis. The authors have developed a new difference method (named the singularity-separating method) for quasi-linear hyperbolic systems of partial differential equations. Its most important feature is that it possesses a high accuracy even for problems with singularities such as schocks, contact discontinuities, rarefaction waves and detonations. Besides the thorough description of the method itself, its mathematical foundation (stability-convergence theory of difference schemes for initial-boundary-value hyperbolic problems) and its application to supersonic flow around bodies are discussed. Further, the method of lines and its application to blunt body problems and conical flow problems are described in detail. This book should soon be an important working basis for both graduate students and researchers in the field of partial differential equations as well as in mathematical physics.
