When Value and Naturalism in Marx was first published in English in 1979, recent controversies in socialist economic theory had been concentrated on the tenability or untenability of Marx's labour theory of value. Marco Lippi's provocative book accepts the Sraffian correction of Marx's account of profits and prices, but goes on to ask the central question: why did Marx identify value with embodied labour-time? The answer, Lippi argues, lies in a strong-though little-discussed-naturalistic strain in Marx's thought. Through a novel analysis of the discussion of circulation costs in Volume Two of Capital, he contends that Marx operated with a concept of 'production in general', as a relationship of man to nature common to all forms of society, in which labour-time appears as the sole real cost. It was this general conception of production, he suggests, that underlay Marx's insistence that profits, interest, rent and faux frais represent no more than a redistribution of a pre-given total-the mass of surplus value, in a system in which total profit equalled total surplus value and total price total value. While Lippi rejects Marx's naturalistic identification of value with embodied labour-time, he claims that the account developed from it of the anarchy of the market, of commodity fetishism, and of the laws of motion of capitalism is in fact logically independent and retains all its empirical validity. Value and Naturalism in Marx, the work of one of the most outstanding younger economists in Italy, reveals the classic economic theory of historical materialism in a quite new light.
Through careful methodological analysis, this book argues that modern macroeconomics has completely overlooked the aggregate nature of the data. In Part I, the authors test and reject the homogeneity assumption using disaggregate data. In Part II, they demonstrate that apart from random flukes, cointegration unidirectional Granger causality and restrictions on parameters do not survive aggregation when heterogeneity is introduced. They conclude that the claim that modern macroeconomics has solid microfoundations is unwarranted. However, some important theory-based models that do not fit aggregate data well in their representative-agent version can be reconciled with aggregate data by introducing heterogeneity.
Machine Learning: A Constraint-Based Approach, Second Edition provides readers with a refreshing look at the basic models and algorithms of machine learning, with an emphasis on current topics of interest that include neural networks and kernel machines. The book presents the information in a truly unified manner that is based on the notion of learning from environmental constraints. It draws a path towards deep integration with machine learning that relies on the idea of adopting multivalued logic formalisms, such as in fuzzy systems. Special attention is given to deep learning, which nicely fits the constrained-based approach followed in this book.The book presents a simpler unified notion of regularization, which is strictly connected with the parsimony principle, including many solved exercises that are classified according to the Donald Knuth ranking of difficulty, which essentially consists of a mix of warm-up exercises that lead to deeper research problems. A software simulator is also included. - Presents, in a unified manner, fundamental machine learning concepts, such as neural networks and kernel machines - Provides in-depth coverage of unsupervised and semi-supervised learning, with new content in hot growth areas such as deep learning - Includes a software simulator for kernel machines and learning from constraints that also covers exercises to facilitate learning - Contains hundreds of solved examples and exercises chosen particularly for their progression of difficulty from simple to complex - Supported by a free, downloadable companion book designed to facilitate students' acquisition of experimental skills
The story of the false entries, good-faith errors, retractions, and mistakes that occurred during the formation of the Periodic Table of Elements as we know it.
The remarkable progress in computer vision over the last few years is, by and large, attributed to deep learning, fueled by the availability of huge sets of labeled data, and paired with the explosive growth of the GPU paradigm. While subscribing to this view, this work criticizes the supposed scientific progress in the field, and proposes the investigation of vision within the framework of information-based laws of nature. This work poses fundamental questions about vision that remain far from understood, leading the reader on a journey populated by novel challenges resonating with the foundations of machine learning. The central thesis proposed is that for a deeper understanding of visual computational processes, it is necessary to look beyond the applications of general purpose machine learning algorithms, and focus instead on appropriate learning theories that take into account the spatiotemporal nature of the visual signal. Serving to inspire and stimulate critical reflection and discussion, yet requiring no prior advanced technical knowledge, the text can naturally be paired with classic textbooks on computer vision to better frame the current state of the art, open problems, and novel potential solutions. As such, it will be of great benefit to graduate and advanced undergraduate students in computer science, computational neuroscience, physics, and other related disciplines.
Evolutionary computing, inspired by the biological world, is one of the emergent technologies of our time. Being essentially a software activity, it has been successfully applied, e.g. for optimization and machine learning in various areas. The tremendous increase in computational power and, more recently, the appearance of a new generation of programmable logic devices allow for a new approach to designing computing machines inspired by biological models: it is now possible to make the hardware itself evolve. This book is based on a workshop on evolvable hardware, held in Lausanne, Switzerland, in October 1995. It reports the state of the art of research in this field and presents two introductory chapters, written with the novice reader in mind.
We propose and implement a framework for characterizing and monitoring the global business cycle. Our framework utilizes high-frequency data, allows us to account for a potentially large amount of missing observations, and is designed to facilitate the updating of global activity estimates as data are released and revisions become available. We apply the framework to the G-7 countries and study various aspects of national and global business cycles, obtaining three main results. First, our measure of the global business cycle, the common G-7 real activity factor, explains a significant amount of cross-country variation and tracks the major global cyclical events of the past forty years. Second, the common G-7 factor and the idiosyncratic country factors play different roles at different times in shaping national economic activity. Finally, the degree of G-7 business cycle synchronization among country factors has changed over time.
Deeply learned, and with a style all his own, Marco Grassi is as at home with Duccio as he is with Norton Simon; Bronzino as with Bernard Berenson; a painting on his desk as with a Last Supper in Florence’s Basilica of Santa Croce. In the Kitchen of Art selects the art conservator and dealer’s most memorable contributions to The New Criterion over a span of nearly twenty years. Beginning with a previously unpublished memoir of his own Florentine upbringing, and continuing with in-depth critical discussions of the greats of Italian art along with recollections of the grandest collectors of the twentieth century, this book shows the art world in the round.
The U.S. business cycle typically leads the European cycle by a few quarters and this can be used to forecast euro area GDP. We investigate whether financial variables carry additional information. We use vector autoregressions (VARs) which include the U.S. and the euro area GDPs as a minimal set of variables as well as growth in the Rest of the World (an aggregation of seven small countries) and selected combinations of financial variables. Impulse responses (in-sample) show that shocks to financial variables influence real activity. However, according to out-of-sample forecast exercises using the Root Mean Square Error (RMSE) metric, this macro-financial linkage would be weak: financial indicators do not improve short and medium term forecasts of real activity in the euro area, even when their timely availability, relative to GDP, is exploited. This result is partly due to the 'average' nature of the RMSE metric: when forecasting ability is assessed as if in real time (conditionally on the information available at the time of the forecast), we find that models using financial variables would have been preferred, ex ante, in several episodes, in particular between 1999 and 2002. This result suggests that one should not discard, on the basis of RMSE statistics, the use of predictive models that include financial variables if there is a theoretical prior that a financial shock is affecting growth.
A family cloaked in secrets. A beguiling woman. A unique setting. Inspector Bordelli is back to solve one of the most difficult cases of his entire career in the sixth book in this atmospheric crime noir series - perfect for fans of Andrea Camilleri. Florence, 1967. It is winter, and one year has passed since the historic and devastating flood of the Arno, though the memories of that day still linger with the stains on the city walls. The anniversary of the flood brings with it a new case for Inspector Bordelli, who is weighed down with remorse for having taken justice into his own hands, and yearning for Eleonora, the woman he's lost, when the mystery opens. A local wealthy industrialist - fiercely loved and respected by everyone he knew - has been found murdered in his grand villa in the Fiesole hills, and the killer has left no trace. With no obvious leads to follow, Bordelli is patiently retracing the victim's last days when he encounters an old friend from the war. Inviting the frail man into his home with the aim of restoring him to strength with good food and wine, Bordelli is yet to realise that this very friend will lead him ever closer to the secrets at the heart of the mystery - starting with a mysterious woman . . .
Initially developed by Savoia-Marchetti as a transport, the aircraft had evolved into a dedicated medium bomber by the time the S.79-I made its combat debut in the Spanish Civil War in 1936. During World War 2, it became Italy's most successful bomber, and the most produced, with around 1370 built between 1936 and early 1944. Although initially hampered by poor tactics, the S.79 bomber crews nonetheless scored sunk a number of Allied vessels, and provided a constant threat to Allied sailors in the Mediterranean in the early stages of the war. In East Africa and the Red Sea the Sparvieri were the most modern bombers in-theatre, proving a challenge to RAF and SAAF biplane fighters. Using specially commissioned full-colour artwork, first-hand accounts and historic photographs, this volume chronicles the history of the S.79's war in the Mediterranean, North African, Balkan, and East African theatres.
The birth and death of firms is one of the main features of the business cycle. Yet mainstream DGSE macroeconomic models mostly ignore this phenomenon, thereby excluding any potential impact of economic policy on the probability of the birth and death of firms. Those DGSE models that do allow for this phenomenon do so at the cost of drastic simplifications, which effectively rule out causal links between the strategic interaction of industrial firms and the macroeconomy. This innovative new book develops a bottom-up, agent-based framework that shows how strategic interactions at the level of oligopolistic firms, and even at the level of individuals, affect entire industrial sectors and the equilibrium of the macroeconomy. It will appeal to academic researchers and graduate students working in computational economics, agent-based modelling and econophysics, as well as mainstream economists interested in learning more about alternatives to DGSE models in macroeconomics.
The Act of Living explores the relation between development and marginality in Ethiopia, one of the fastest growing economies in Africa. Replete with richly depicted characters and multi-layered narratives on history, everyday life and visions of the future, Marco Di Nunzio's ethnography of hustling and street life is an investigation of what is to live, hope and act in the face of the failing promises of development and change. Di Nunzio follows the life trajectories of two men, "Haile" and "Ibrahim," as they grow up in the Ethiopian capital Addis Ababa, enter street life to get by, and turn to the city's expanding economies of work and entrepreneurship to search for a better life. Apparently favourable circumstances of development have not helped them achieve social improvement. As their condition of marginality endures, the two men embark in restless attempts to transform living into a site for hope and possibility. By narrating Haile and Ibrahim's lives, The Act of Living explores how and why development continues to fail the poor, how marginality is understood and acted upon in a time of promise, and why poor people's claims for open-endedness can lead to better and more just alternative futures. Tying together anthropology, African studies, political science, and urban studies, Di Nunzio takes readers on a bold exploration of the meaning of existence, hope, marginality, and street life.
Aleister Crowley (1875-1947) is one of the most famous and significant authors in the history of western esotericism. Crowley has been long ignored by scholars of religion whilst the stories of magical and sexual practice which circulate about him continue to attract popular interest. "Aleister Crowley and the Temptation of Politics" looks at the man behind the myth - by setting him firmly within the politics of his time - and the development of his ideas through his extensive and extraordinarily varied writings. Crowley was a rationalist, sympathetic to the values of the Enlightenment, but also a romantic and a reactionary. His search for an alternative way to express his religious feelings led him to elaborate his own vision of social and political change. Crowley's complex politics led to his involvement with many key individuals, organisations and groups of his day - the secret service of various countries, the German Nazi party, Russian political activists, journalists and politicians of various persuasions, as well as other writers - both in Europe and America. "Aleister Crowley and the Temptation of Politics" presents a life of ideas, an examination of a man shaped by and shaping the politics of his times.
This volume takes cue from the idea that the thought of no philosopher can be understood without considering it as the result of a lively dialogue with other thinkers. On this ground, it addresses the ways in which René Descartes’s philosophy evolved and was progressively understood by intellectuals from different contexts and eras, either by considering direct interlocutors of Descartes such as Isaac Beeckman and Elisabeth of Bohemia, thinkers who developed upon his ideas and on particular topics as Nicolas Malebranche or Thomas Willis, those who adapted his overall methodology in developing new systems of knowledge as Johannes Clauberg and Pierre-Sylvain Régis, and contemporary thinkers from continental and analytic traditions like Emanuele Severino and Peter Strawson.
