The demand for selective organic reactions is growing more acute everyday. Indeed, greater product selectivity has an important impact on energy and resource utilization, in terms of reduced process energy requirements for product separation and purification, in terms of low-value by-products, and in terms of environmental acceptance and compatibility. Moreover, more and more chemicals, especially pharmaceuticals, have to be sold in an optically active form. The search for selectivity constitutes a tremendous challenge for the chemists. In the last two decades, homogeneous transition metal based catalysis has emerged as one of the most promising tools for obtaining selectivity. In connection with developments in this area, this book contains updated and expanded versions of most of the lectures presented at a Cornett course held in Trieste (Italy) in 1989 and sponsored by the European Community. A primary aim is to cultivate a deeper understanding of the parameters that govern the selectivities and stimulate a wider utilization of transition metal based catalysis in organic synthesis. All aspects of selectivity, chemo-, regio-, stereo- and enantioselectivity are considered and illustrated by applications in various fields or organic synthesis. The impact of catalysis in oxydation, reduction, carbonylation reactions, carbene chemistry, in Ni and Pd promoted dimerizations, oligomerizations as well as fonctionalisations is stressed, quite often with special emphasis laid on reaction mechanisms. In this aspect, the last chapter examplifies the interest of high pressure NMR and IR when investigating the nature of reaction intermediates in homogeneous reactions.

The XXth meeting of the IAU in Australia in 1973 made the venue for the IAU Symposium No. 59 on Stellar Instability and Evolution, at Mount Stromlo Obser vatory on August 16-18, a very appropriate one. Many of the current and former staff of Mount Stromlo Observatory (operated by the Australian National Univer sity) have specialized in the study of variable stars and it was with considerable pleasure that Mount Stromlo Observatory accepted the responsibility of hosting and making the local arrangements for IAU Symposium No. 59. The Scientific Organizing Committee was particularly active in formulating the program and comprised Drs N. Baker, P. Demarque, M. Feast, G. Herbig, I. Iben, P. Ledoux, J. Ostriker and E. Schatzman. The aim of the Committee was to integrate the review and contributed papers on the particular instability mechanisms involved, their observational manifestations and their relation to the internal structure of the star as inferred from its evolutionary history. The Local Organizing Committee consisted of Miss P. Petrie and A. W. Rodgers."

Bullying, particularly among school-age children, is a major public health problem both domestically and internationally. Current estimates suggest that nearly 30% of American adolescents reported at least moderate bullying experiences as the bully, the victim, or both. Specifically, of a nationally representative sample of adolescents, 13% reported being a bully, 11% reported being a victim of bullying, and 6% reported being both a bully and a victim. This book provides researchers, prevention specialists, and health educators with tools to measure a range of bullying experiences: bully perpetration, bully victimisation, bully-victim experiences and bystander experiences. The ability to measure bullying experiences broadly and completely is crucial to the success of these activities.

This edited volume examines European approaches to migrants, European Union migration policies, and the EU-Turkey refugee agreement through macro-level and micro-level analysis. It analyzes issues related to migration in Turkey and Syria and specifically studies at the Syrian refugee crisis. The contributors explore the migration phenomenon through economic and judicial perspectives.

In Tropical Aesthetics of Black Modernism, Samantha A. Noel investigates how Black Caribbean and American artists of the early twentieth century responded to and challenged colonial and other white-dominant regimes through tropicalist representation. With depictions of tropical scenery and landscapes situated throughout the African diaspora, performances staged in tropical settings, and bodily expressions of tropicality during Carnival, artists such as Aaron Douglas, Wifredo Lam, Josephine Baker, and Maya Angelou developed what Noel calls "tropical aesthetics"-using art to name and reclaim spaces of Black sovereignty. As a unifying element in the Caribbean modern art movement and the Harlem Renaissance, tropical aesthetics became a way for visual artists and performers to express their sense of belonging to and rootedness in a place. Tropical aesthetics, Noel contends, became central to these artists' identities and creative processes while enabling them to craft alternative Black diasporic histories. In outlining the centrality of tropical aesthetics in the artistic and cultural practices of Black modernist art, Noel recasts understandings of African diasporic art.

Too often America looks outside of herself, at other cultures, for guidance to improve. America seems to be hypercritical of itself and it has become the trend to look to Asia for examples in order to implement improvements. The picture below shows me at the Forbidden Palace. while teaching in China and also having done extensive studies of the Chinese educational system, I have grown to appreciate the historical focus of China on education going back as far as Confucius and beyond. America can certainly learn from the Chinese and they are certainly learning from us. However, it is a mistake to seek to implement Chinese methodology into the American system without modifications being made. There are great differences in the two systems and to walk away from the strengths of the American system to indiscriminately adopt the strengths of the Chinese system is to throw the baby out with the bath water. The Chinese are very insightful and know this. this is why they look to America and other systems to discover the best of those systems, adapt it to the current Chinese system, and graft it on making it a part of the living ever-evolving structure gaining strength, endurance, and efficacy. This book examines these other systems and compares them with America's system. We can learn from China, Japan, and especially France and, like the Chinese, graft on the best of the other systems to ours making it stronger and more efficacious. As the Chinese welcomed me and all Americans, so we should welcome them and the best of their system and graft it into our historically incomparable educational system once again making it an formidable force to be reckoned with worldwide.
