A Problem Seminar

There was once a bumper sticker that read, "Remember the good old days when air was clean and sex was dirty?" Indeed, some of us are old enough to remember not only those good old days, but even the days when Math was/un(!), not the ponderous THEOREM, PROOF, THEOREM, PROOF, . . . , but the whimsical, "I've got a good prob lem. " Why did the mood change? What misguided educational philoso phy transformed graduate mathematics from a passionate activity to a form of passive scholarship? In less sentimental terms, why have the graduate schools dropped the Problem Seminar? We therefore offer "A Problem Seminar" to those students who haven't enjoyed the fun and games of problem solving. CONTENTS Preface v Format I Problems 3 Estimation Theory 11 Generating Functions 17 Limits of Integrals 19 Expectations 21 Prime Factors 23 Category Arguments 25 Convexity 27 Hints 29 Solutions 41 FORMAT This book has three parts: first, the list of problems, briefly punctuated by some descriptive pages; second, a list of hints, which are merely meant as words to the (very) wise; and third, the (almost) complete solutions. Thus, the problems can be viewed on any of three levels: as somewhat difficult challenges (without the hints), as more routine problems (with the hints), or as a textbook on "how to solve it" (when the solutions are read). Of course it is our hope that the book can be enjoyed on any of these three levels.

The contributions in this book analyse the policy challenges of taxation in developing countries, including corruption, tax evasion, and ineffective political structures. After a comprehensive overview, each chapter uses modern empirical methods to study a single critical issue essential to understanding the effects of taxes on development. Topics addressed include the effect of taxation on foreign direct investment; forms of corruption, tax evasion, and tax avoidance that are specific to developing countries; and issues related to political structure, including the negative effects of fiscal decentralization on the effectiveness of developmental aid and the relationship between democracy and taxation in Asian, Latin American, and European Union countries that have recently experienced both political and economic transitions.

‘Whiteness’ is a politically constructed category which needs to be understood and dismantled because the system of racism so embedded within our society harms us all. It has profound implications for human psychology, an understanding of which is essential for supporting the movement for change. This book explores these implications from a psychoanalytic and Jungian analytic perspective. The ‘fragility’ of whiteness, the colour-blind approach and the silencing process of disavowal as they develop in the childhood of white liberal families are considered as means of maintaining white privilege and racism. A critique of the colonial roots of psychoanalytic theories of Freud and Jung leads to questioning the de-linking of the individual from society in modern day analytic thinking. The concept of the cultural complex is suggested as a useful means of connecting the individual and the social. Examples from the author’s clinical practice as well as from public life are used to illustrate the argument. Relatively few black people join the psychoanalytic profession and those who do describe training and membership as a difficult and painful process. How racism operates in clinical work, supervision and our institutions is explored, and whilst it can seem an intractable problem, proposals are given for ways forward. This book will be of great importance to psychoanalysts, psychotherapists, social workers and all those with an interest in the role of white privilege on mental health.
