The eleventh COSPAR colloquium The Outer Heliosphere: The Next Frontiers was held in Potsdam, Germany, from 24-28 July, 2000, and is the second dedicated to this subject after the first one held in Warsaw, Poland in 1989.
Roughly a century has passed after the first ideas by Oliver Lodge, George Francis Fitzgerald and Kristan Birkeland about particle clouds emanating from the Sun and interacting with the Earth environment. Only a few decades after the formulation of the concepts of a continuous solar corpuscular radiation by Ludwig Bierman and a solar wind by Eugene Parker, heliospheric physics has evolved into an important branch of astrophysical research. Numerous spacecraft missions have increased the knowledge about the heliosphere tremendously. Now, at the beginning of a new millenium it seems possible, by newly developed propulasion technologies to send a spacecraft beyond the boundaries of the heliosphere. Such an Interstellar Proce will start the in-situ exploration of interstellar space and, thus, can be considered as the first true astrophysical spacecraft. The year 2000 appeared to be a highly welcome occassion to review the achievements since the last COSPAR Colloquia 11 years ago, to summarize the present developments and to give new impulse for future activities in heliospheric research.

Appraisal theory has become one of the most active aproaches in the domain of emotion psychology. The appraisal process consists of the subjective evaluation that occurs during the individual's encounter with significant events in the environment, thus determining the nature of the emotional reaction and experience. The organism's interpretation of events and situations elicits and differentiates its emotional responses, although the exact processes involved and the limits of the theory are still a matter of debate and are currently the object of active research. This volume is intended to become the primary source of information on appraisal for all those interested in emotion, from beginning graduate students to accomplished researchers in emotion psychology.

With spears and arrows, atl-atls and slings, the people of the New World fought to defend themselves against European invasion and conquest. Over a century of scholarship on warfare has substantially enhanced our understanding of the scope and scale of violent conflict in Pre-Columbian America. Yet we still struggle to understand the nuances of indigenous warfare and its importance for native politics and society. This volume sheds new light on the nature of war in Mesoamerica and the Andes. Relying on methodological and theoretical developments in anthropological archaeology, bioarchaeology, and ethnohistory, contributors highlight the particularities of warfare in indigenous societies and examine the commonalities of warfare in cross-cultural perspective. Their essays focus on place and the body, as they explore the importance of captive-taking, sacrifice, performance, and political history in the conduct of war. Observers have debated whether the indigenous peoples of the Americas were distinctly noble or frightfully savage in their way of war. This volume shows that such polarized positions are unfounded. By focusing on the nuances of indigenous violent conflict, the contributors demonstrate that war in the Americas was much like war elsewhere in the ancient and modern world: strategic, political, bloody, socially productive, yet terribly destructive.

From the tombs of the elite to the graves of commoners, mortuary remains offer rich insights into Classic Maya society. In Mortuary Landscapes of the Classic Maya: Rituals of Body and Soul, the anthropological archaeologist and bioarchaeologist Andrew K. Scherer explores the broad range of burial practices among the Maya of the Classic period (AD 250-900), integrating information gleaned from his own fieldwork with insights from the fields of iconography, epigraphy, and ethnography to illuminate this society's rich funerary traditions. Scherer's study of burials along the Usumacinta River at the Mexican-Guatemalan border and in the Central Peten region of Guatemala-areas that include Piedras Negras, El Kinel, Tecolote, El Zotz, and Yaxha-reveals commonalities and differences among royal, elite, and commoner mortuary practices. By analyzing skeletons containing dental and cranial modifications, as well as the adornments of interred bodies, Scherer probes Classic Maya conceptions of body, wellness, and the afterlife. Scherer also moves beyond the body to look at the spatial orientation of the burials and their integration into the architecture of Maya communities. Taking a unique interdisciplinary approach, the author examines how Classic Maya deathways can expand our understanding of this society's beliefs and traditions, making Mortuary Landscapes of the Classic Maya an important step forward in Mesoamerican archeology.
