Book Description

Immanuel Wallerstein's World-System theory made a big impact on International Political Economy when it was first formulated in the early 1980s. Although subsequently criticised, the recent demise of the Soviet system's historic attempt to delink from global capitalism has provided a perhaps unanticipated confirmation of the profundity of its insights. Now with this new book, Wallerstein and a team of colleagues from the Fernand Braudel Center for the Study of Economies, Historical Systems and Civilizations take world-system theory a major step forward.

The choices we need to make over the next 25 years.......2000-04-09

This is an important albeit not uncontroversial contribution to the field of international political economy. The book tries to answer the question whether the world capitalist system is in crisis and the paths available for future world development. The works are firmly located within the world system thesis expounded by Wallerstein in many of his previous works.

The book intoruduces the concept of 6 vectors within which future paths can be examined. These are the inter-state system; world production; world labour force; human welfare; cohesion of states; and the structures of knowledge.

The book displays the weaknesses inherent in the world system thesis. These include overstating the degree of integration of the economies of the world and thus not taking into account the emergence of "non-states" run either by armed bandits or by organised crime.

The book does not deal adequately with the current state of the state. Given the debate around MNCs and their increasing expansion into areas which were the domain of the state this is an issue needing serious appraisal.

The depiction of this era as being a post US hegemonic era is also an area which will be contested by many writers, not least of all the Fukuyama's of the world.

Wallerstein concludes that the future depends onm how the following factors develop: * the extent to which there is loyalty to citizenship;

Book Description

Designed for undergraduate courses in Spacecraft Dynamics and Orbital Mechanics, this new edition offers a three-dimensional treatment of dynamics discussions of rigid body dynamics, rocket trajectories, and the space environment. An expert in his field, author William E. Wiesel presents a wealth of information in an easy-to-understand manner without the daunting mathematical rigor of graduate texts. Reference is made to actual flight vehicles and satellites to give students background on the type of work currently being done in this field.

Jonathan Erdmann.......2004-11-17

I am an aerospace engineering student at the undergraduate level and used this text in an astrodynamics course. I felt that the author did a good job developing the fundamentals needed but lacked some important derivations that would have been usefull at times. I also enjoyed some of the non-technical aspects of this book as well, such as the sections devoted to our solar system and its characteristics.

I used this book along with Fundamentals of Astrodynamics by Roger Bate, Donald Mueller, and Jerry White - which has been used at my university for more than twenty-five years. I would suggest purchasing both books at once as doing so will give both a modern viewpoint of the subject as well as the derivations needed to understand the basics.

Good introductory and reference book.......2004-09-05

This book is easy to read and contains several good exercises. Ideal for undergrads looking to learn about orbital mechanics, attitude control, and trajectories. Also excellent as a quick reference for more advanced students. The only complaint I have about the book is that some of the diagrams are not very well drawn, which can be somewhat annoying, especially if it's for a homework problem!

Aerospace Engineering Student.......2004-02-21

This book is really designed for a beginner level class in astrodynamics. I used it for my beginner class, and I found the book to be extremely helpful. Now, taking graduate level courses in astrodynamics, I still use Wiesel's book! When I need to look up basic formulas, I use this book often. If you're looking for a more advanced book in astrodynamics, look into Vallado's Fundamentals of Astrodynamics and Applications. However, for the beginner level, Wiesel does an excellent job of explaining the material and presenting the mathematics behind the equations.

Book Description

How do we account for experiences of trauma and memory in multicultural and "globalized" societies? World Memory blends the study of trauma and memory with perspectives from postcolonial theory to explore a range of traumatic personal and socio-historical experiences: 9/11/01, the Holocaust, Stolen Generations, Apartheid, racism, sexual abuse, migration, and Diaspora. From diverse disciplinary bases, the writers examine psychoanalytic, artistic, literary, and vernacular accounts of trauma, collectively revealing what happens when languages of memory traverse boundaries of culture, space, and time.

Book Description

The Trajectory of Change charts a course for the growing, international movement against corporate globalization. Michael Albert, a longtime activist and analyst of popular struggles, challenges the movement to reach out to "ordinary people" by demonstrating how their lives are negatively affected by creeping corporatism.

Albert connects issues confronting working people in the United States (such as access to health care, workplace rights and safety, declining wages, and unemployment) to a critique of institutions that currently dominate the global economy. And he offers a compelling argument for a strategy based on civil disobedience and protest rather than individual acts of vandalism or violence.

Albert also suggests reasons for the recent revival of political protest, from the Battle in Seattle to the demonstrations in Quebec,Canada, and Genoa, Italy. At the same time, he argues that it isn't enough for protesters to stand against global economic injustice. To be effective, Albert argues that we need to develop a clear vision of what we stand for. He makes the case for collectively creating a vision of a participatory, democratic, and egalitarian society.

Michael Albert is a founder of Z Magazine and Z Net, a web site and electronic commentary service based in Woods Hole, Massachusetts. He also co-founded South End Press. He is the author of Looking Forward (with Robert Hahnel) and Stop the Killing Trade, among other books on economics and social change.

not communism.......2006-03-13

This is an excellent book by a well read, thoughtful activist who is, by the way, not a communist. Many of Albert's other works, along with Robin Hahnel, describe an alternative economic system to both capitalism and communism called a participatory economy - parecon for short. The Trajectory of Change is written to point out tools and activities that we can use so that we will some day achieve it.

Contrary to what the other reviewer says, this alternative system would not destroy incentive, take away peoples dreams, place everyone under State rule or take away anything from the vast majority of people. Albert and Hahnel describe a system that would give people real incentive by compensating everyone for their effort and sacrifice; that would empower people's dreams through eliminating the limitations of a system based in private ownership of productive property, corporate hierarchies, disempowering jobs and an unfair, inefficient market; that would eliminate the State as we've known it by replacing it with a bottom-up federation of democratic councils in which everyone would participate at the base; and in which no one, rather than the State or capitalists, would own the productive property, thus allowing everyone to benefit from it. As well, less than 20% of the population owns these things now and subsequently use them to exploit the other 80 plus percent. The only people that need fear parecon are the corporate CEOs and VPs, Presidents, Prime Ministers, and the rest of the ruling elite.

Communism.......2005-03-02

This Michael Albert is a Communist. Period! The problem with his logic is there is no logic. A system which destroys the incentive to go beyond others and excel is a system of medieval lunacy. The world economies over the last 250 years are based on men and women pursuing their dreams. Socialism takes this away from people who want more in life. To place everyone under State Rule would be disastrous for all on earth.
Again these left wing people can't see beyond their front yard.
They fail to see the consequences of their actions.They are simply communist and thieves who want to take away from you and me and give to the state to be distributed equally. Now tell me why work hard if their is no reward. These people should scare everyone.

strategy for revolution.......2002-05-18

In The Trajectory of Change, Michael Albert offers his criticisms and suggestions for the left, a movement that has yet to live up to its potential. He begins from the assumption that mass mobilization is the only way to force fundamental social change. Elites and other privileged groups don't respond to well-reasoned calls for equality, only to popular and militant demands for change -- as seen in the struggles for labor rights, civil rights, women's rights, and against the Vietnam war. Yet activists frequently forget the need to mobilize and concentrate instead on refining their own tactics, distancing themselves from the people they need to actually win change.

If we accept the need to organize ever greater numbers of people with ever greater militancy, where do go then? According to Albert we first have to reach out beyond social barriers like race and class (leftist university students need to talk to people in sports bars), and then we have to give a lot of thought to the "stickiness problem". That is, why do so few people stick with left activism after being exposed to it?

The two key issues Albert brings up are a lack of vision and a culture of personal criticism. If the movement can offer incisive critiques of social inequality but has no idea what institutions it wants to put in place, isn't activism literally pointless? And if interpersonal relations in the left have more to do with castigating activists who eat at McDonald's, wear Nikes, or watch TV than with making friends and partying, who would want to stay?

Running through each of Albert's arguments is the idea that we have to start paying attention to class. The left is now highly sensitive to race and gender inequality, both within and without the movement. So why is class inequality ignored in society and reproduced in our organizations? Albert has his own highly original explanation for why attention to class, once the preeminent target, virtually disappeared from the left (pp. 87-103), but the ultimate point is that classlessness needs to become a priority again -- both because the left opposes oppression and because working people won't find the left attractive until it stops reproducing the hierarchical forms of organization they suffer from every day in their work lives.

Book Description

Statistical Methods in Quantum Optics 2 - Non-Classical Fields continues the development of the methods used in quantum optics to treat open quantum systems and their fluctuations. Its early chapters build upon the phase-space methods introduced in the first volume Statistical Methods in Quantum Optics 1 - Matter Equations and Fokker-Planck Equations: the difficulties these methods face in treating non-classical light are exposed, where the regime of large fluctuations – failure of the system size expansion – is shown to be particularly problematic. Cavity QED is adopted as a natural vehicle for extending quantum noise theory into this regime. In response to the issues raised, the theory of quantum trajectories is presented as a universal approach to the treatment of fluctuations in open quantum systems.

This book presents its material at a level suitable for beginning researchers or students in an advanced course in quantum optics, or a course in quantum mechanics or statistical physics that deals with open quantum systems. The text is complemented by exercises and interspersed notes that point the reader to side issues or a deeper exploration of the material presented.

Book Description

Life-course criminology has generated new energy and provoked sharp debate over competing ideas about the fundamental relationship between age and crime. A major catalyst for this debate – a 2003 American Society of Criminology (ASC) conference session entitled "Age, Crime, and Human Development: The Future of Life-Course Criminology," chaired by the editors of this issue – provided a springboard for this special issue of The Annals.

With an eye to the future, this special issue provides critical debate on patterns of age and crime across the full life course – from infancy to late adulthood. Criminal career topics such as onset, continuation, termination, and career length are also discussed, along with the viability of developmental and taxonomic theories of crime, the suitability of existing data archives to test theories, and the prospects for marrying longitudinal and experimental studies.

The distinguished papers that appear in this compelling collection include the full set of presentations from the inaugural Albany Symposium on Crime and Justice: "Developmental Criminology and Its Discontents: Offender Typologies and Trajectories of Crime," which took place in April 2005 and built upon the questions raised at the ASC conference session. In addition to the revised original papers and commentaries from the Albany symposium, this journal also includes never-before-published responses to the commentaries by each of the papers' authors. An overview by Alfred Blumstein of the central issues raised at the symposium and a book-review essay by Hans-Jürgen Kerner rounds out the volume and collectively provides a comprehensive representation of the provocative discussion ignited by these intriguing session panels.

Centered on the fundamental discussions raised by the life-course paradigm in criminology, this historical issue of The Annals will potentially shape the theoretical and research agenda for years to come. It is an essential resource for scholars, researchers, and practitioners in the fields of criminology, sociology, psychology, criminal justice, aging, human development, and social policy.

With a diverse set of viewpoints, this well-rounded and in-depth look at age, crime, and human development is a valuable contribution to existing studies and will serve as a foundation for future research into this lively topic.
