This first volume of the Collected Works of Mihaly Csikszentmihalyi represents his work on Art and Creativity. Starting with his seminal 1964 study on creativity up to his 2010 publication in Newsweek, the volume spans over four decades of research and writing and clearly shows Csikszentmihalyi’s own development as an academic, psychologist, researcher and person. Unconventional and unorthodox in his approach, Csikszentmihalyi chose the topic of creativity as a field of study believing it would help him be a better psychologist and advance his understanding of how to live a better life.The chapters in this volume trace the history of the study of creativity back to the days of Guilford and research on IQ and Jacob Getzels’ work on creativity and intelligence. Firmly grounded in that history, yet extending it in new directions, Mihaly Csikszentmihalyi started his life-long study on artistic creativity. His first extensive study at the School of the Art Institute of Chicago enabled him to observe, test and interview fine art students drawing in a studio. The study formed the very basis of all his work on the subject and has resulted in several articles, represented in this volume, on such creativity-related concepts as problem solving versus problem finding, the personality of the artist, the influence of the social context, creativity as a social construction, developmental issues and flow. The main contribution to the topic of creativity and also the main concept explored in this volume, is the Systems Model of Creativity. Seven chapters in this volume discuss the development of this conceptual model and theory.

The aim of this monograph is to present some of the basic ideas and results in pure combinatory logic and their applications to some topics in proof theory, and also to present some work of my own. Some of the material in chapter 1 and 3 has already appeared in my notes Introduction to Combinatory Logic. It appears here in revised form since the presen­ tation in my notes is inaccurate in several respects. I would like to express my gratitude to Stig Kanger for his invalu­ able advice and encouragement and also for his assistance in a wide variety of matters concerned with my study in Uppsala. I am also in­ debted to Per Martin-USf for many valuable and instructive conversa­ tions. As will be seen in chapter 4 and 5, I also owe much to the work of Dag Prawitz and W. W. Tait. My thanks also to Craig McKay who read the manuscript and made valuable suggestions. I want, however, to emphasize that the shortcomings that no doubt can be found, are my sole responsibility. Uppsala, February 1972.

This is an introductory graduate course on quantum mechanics, which is presented in its general form by stressing the operator approach. Representations of the algebra of the harmonic oscillator and of the algebra of angular momentum are determined in chapters 1 and 2 respectively. The algebra of angular momentum is enlarged by adding the position operator so that the algebra can be used to describe rigid and non-rigid rotating molecules. The combination of quantum physical systems using direct-product spaces is discussed in chapter 3. The theory is used to describe a vibrating rotator, and the theoretical predictions are then compared with data for a vibrating and rotating diatomic molecule. The formalism of first- and second-order non-degenerate perturbation theory and first-order degenerate perturbation theory are derived in chapter 4. Time development is described in chapter 5 using either the Schroedinger equation of motion or the Heisenberg’s one. An elementary mathematical tutorial forms a useful appendix for the readers who don’t have prior knowledge of the general mathematical structure of quantum mechanics.

In the last few decades the accumulation of large amounts of in­ formation in numerous applications. has stimtllated an increased in­ terest in multivariate analysis. Computer technologies allow one to use multi-dimensional and multi-parametric models successfully. At the same time, an interest arose in statistical analysis with a de­ ficiency of sample data. Nevertheless, it is difficult to describe the recent state of affairs in applied multivariate methods as satisfactory. Unimprovable (dominating) statistical procedures are still unknown except for a few specific cases. The simplest problem of estimat­ ing the mean vector with minimum quadratic risk is unsolved, even for normal distributions. Commonly used standard linear multivari­ ate procedures based on the inversion of sample covariance matrices can lead to unstable results or provide no solution in dependence of data. Programs included in standard statistical packages cannot process 'multi-collinear data' and there are no theoretical recommen­ dations except to ignore a part of the data. The probability of data degeneration increases with the dimension n, and for n > N, where N is the sample size, the sample covariance matrix has no inverse. Thus nearly all conventional linear methods of multivariate statis­ tics prove to be unreliable or even not applicable to high-dimensional data.

From the mysterious powers and forces peculiar to both individual and community that can turn our lives into either good or bad lives, I wish to point to two such powers being at the same time different in their own nature and yet closely related to each other: The powers that emerge from exemplary persons and leaders. Understood as basic to both sociology and the philosophy of history, it comes to us as no surprise that the problem of exemplary persons and leaders - along with the questions of the qualities types, selections and education of leaders; forms of unison existing be­ tween leaders and their followers, all of which belonging to the subdivisions of this problem - must be a burning problem for a people whose historical leaders from all walks of life have, in part, been swept away by wars and revolutions. This fact we also find in all salient epochs of history characterized more or less by changes in leadership. It is precisely for this reason that in our own time every group appears to struggle ever so hard with this problem, namely, who their leaders should be. This pertains equally to a group within a party, to a class, to occupations, to unions, to various schools or present-day youth movements, and even to religious and ecclesias­ tical groupings. Beyond any comparison, there is yearning everywhere for lead­ ership.

Qualitative analyses of young children’s learning in natural settings are rare, so this new book will make educators sit up and pay attention. It lays out a Nordic, or continental European teaching and learning paradigm whose didactic framework is distinct from the Anglo-American system. This analysis, which features contributions and case studies from researchers in a range of subjects, is built on principles such as the learner’s perspective, establishing sufficient intersubjectivity, ‘pointing out’, and informing experience linguistically. After clarifying some historical background, the book discusses the contemporary emphasis in early childhood education on pedagogy/learning. What should ‘didactics’ mean in educating young children?The book examines the opportunities for learning that teachers provide for children in early childhood education, as well as how children respond to these opportunities. It presents empirical studies from a variety of naturalistic settings, including mathematics, making visual art, ecology, music, dance, literacy and story-telling, as well as learning about gender, morality and democracy. The authors seek to answer key questions about the processes involved in both teaching and learning. What challenges do teachers face as they try to expand children’s knowledge in various fields of learning? How do they respond to these challenges, and what can we learn about children’s corresponding uptake? What now requires further research? One key distinction in researching children’s learning is between studies that look at ‘process’ and those that analyze ‘product’. In the tradition of Piaget, Vygotsky and Werner, as well as Mercer and Valsiner’s more recent work, this book advocates the importance and relative rareness of the former type of study.

The idea of producing this book of case histories from general family prac­ tice was only a twinkle in the editors' eyes until October 1980, when in a room in the Marriott Hotel in New Orleans, the editors met with John Fry, Joseph Levenstein and Bill Jackson to discuss new book projects. The idea was put to the group, which endorsed it enthusiastically. Encouraged by this and by John Fry's advice, the conception of The Nature of General Family Practice took place. It was agreed that to illustrate the universal nature of general family prac­ tice it would be useful to collect case histories from all around the world, that for preference they should be brief, and that they should be ac­ companied by major questions and sub-questions, but no answers. The name 'Vignettes' was applied to these cases and their questions. Subsequently, well over a hundred family physicians were asked by letter to provide ten vignettes. Sixty doctors from ten countries accepted the invitation and forwarded their contributions during the second half of 1981. Almost all of those who, for a variety of reasons were unable to contribute, said they liked the idea and looked forward to using the final product. Altogether, over 600 vignettes were received, and 583 selected for final inclusion.

I wish to express, first of all, my profound gratitude to Professor J. M. Bochenski, without whose assistance the present work would have not been possible. To be concise, I would like to state that his contribution to this book may be viewed at three levels: (1) that of the general spirit, (2) that of the specific ideas, theses or approaches which are expressed in its pages, (3) that of this work qua doctoral dissertation. The general spirit which has guided my research coincides with that underlying Professor :Oochenski's own works, in particular his Formale Logik (Munchen 1956). Moreover, the particular occasion which suggested my investigation was a statement included in that book according to which the literature in the field still lacked a detailed work on Frege (p. 317). I wish, likewise, to express my gratitude to other professors of the University of Fribourg for their generous help. I mention especially Professors P. Wyser, M. D. Philippe, N. Luyten, and V. Kuiper. I have also benefited from Professor E. Specker's lectures at the Eidge- nossische Technische Hochschule (ZUrich) and from Professor Olof Gigon's lectures at the University of Bern.From an earlier period I wish to express my gratitude to the professors of the philosophy department of the Universidad Nacional de Buenos Aires, especially the late Professor Francisco Romero. The Swiss National Library (Bern) has greatly facilitated access to bibliographical sources, and the library of the University of Munster (Westphalien) has kindly provided microfilms of Frege's Nachlap.

In the recent educational research literature, it has been asserted that ethnic or cultural groups have their own distinctive epistemologies, and that these have been given short shrift by the dominant social group.  Educational research, then, is pursued within a framework that embodies assumptions about knowledge and knowledge production that reflect the interests and historical traditions of this dominant group. In such arguments, however, some relevant philosophical issues remain unresolved, such as what claims about culturally distinctive epistemologies mean, precisely, and how they relate to traditional epistemological distinctions between beliefs and knowledge. Furthermore, can these ways of establishing knowledge stand up to critical scrutiny? This volume marshals a variety of resources to pursue such open questions in a lively and accessible way: a critical literature review, analyses from philosophers of education who have different positions on the key issues, a roundtable discussion, and interactions between the two editors, who sometimes disagree. It also employs the work of prominent feminist epistemologists who have investigated parallel issues with sophistication. This volume does not settle the question of culturally distinctive epistemologies, but teases out the various philosophical, sociological and political aspects of the issue so that the debate can continue with greater clarity.

Over the last 30 years, Dr. Nikita V. Chukanov has collected IR spectra of  about  2000  mineral species,  including  247  holotype samples.  In  this  book, he presents  3309 spectra of these  minerals with   detailed   description   and   analytical  data  for  reference samples.  In  the  course  of this work, about 150 new mineral species have been discovered. After an introductory chapter, infrared spectra of minerals are given together with the descriptions of standard samples used (occurrence, appearance, associated minerals, empirical formula etc.) and some comments. Sections are organized according to different  classes  of  compounds  (silicates,  phosphates, arsenates, oxides etc.).

Farming Systems Research has three core characteristics: it builds on systems thinking, it depends on the close collaboration between social and biophysical sciences, and it relies on participation to build co-learning processes. Farming Systems Research posits that to contribute towards sustainable rural development, both interdisciplinary collaborations and local actor engagement are needed. Together, they allow for changes in understanding and changes in practices. This book gives an overview of the insights generated in 20 years of Farming Systems Research. It retraces the emergence and development of Farming Systems Research in Europe, summarises the state-of-the-art for key areas, and provides an outlook on new explorations, especially those tackling the dynamic nature of farming systems and their interaction with the natural environment and the context of action.

Restoration ecology, as a scientific discipline, developed from practitioners’ efforts to restore degraded land, with interest also coming from applied ecologists attracted by the potential for restoration projects to apply and/or test developing theories on ecosystem development. Since then, forest landscape restoration (FLR) has emerged as a practical approach to forest restoration particularly in developing countries, where an approach which is both large-scale and focuses on meeting human needs is required.Yet despite increased investigation into both the biological and social aspects of FLR, there has so far been little success in systematically integrating these two complementary strands. Bringing experts in landscape studies, natural resource management and forest restoration, together with those experienced in conflict management, environmental economics and urban studies, this book bridges that gap to define the nature and potential of FLR as a truly multidisciplinary approach to a global environmental problem. The book will provide a valuable reference to graduate students and researchers interested in ecological restoration, forest ecology and management, as well as to professionals in environmental restoration, natural resource management, conservation, and environmental policy.

While restoration ecology has traditionally aimed to re-create some putative more ‘natural’ ecological state, forest landscape restoration (FLR) has emerged over the last decade as an approach aimed more at restoring natural functions, while focusing on meeting human needs.With a view to exploring the practical potential of this approach, this book draws together a team of experts from the natural and social sciences to discuss its success so far in addressing critical issues such as biodiversity, ecological function, and human livelihoods. Applying principles of landscape ecology, restoration ecology, planning theory and conflict management, the book presents a series of case studies which document the approach, and discusses how the approach can help with priority setting for the future.The book will provide a valuable reference to graduate students and researchers interested in ecological restoration, forest ecology and management, as well as to professionals in environmental restoration, natural resource management, conservation, and environmental policy.

This book grew out of my confusion. If logic is objective how can there be so many logics? Is there one right logic, or many right ones? Is there some underlying unity that connects them? What is the significance of the mathematical theorems about logic which I've learned if they have no connection to our everyday reasoning? The answers I propose revolve around the perception that what one pays attention to in reasoning determines which logic is appropriate. The act of abstracting from our reasoning in our usual language is the stepping stone from reasoned argument to logic. We cannot take this step alone, for we reason together: logic is reasoning which has some objective value. For you to understand my answers, or perhaps better, conjectures, I have retraced my steps: from the concrete to the abstract, from examples, to general theory, to further confirming examples, to reflections on the significance of the work.
