Ocean island volcanoes constitute some of the most prominent and rapidly-formed features on Earth, and yet they cannot be explained by conventional plate tectonics. Although typically associated with intraplate settings (hotspots), these volcanoes also occur in different geodynamic settings (near mid-ocean ridges). The nature of ocean island magmatism is still the subject of intense debate within the geological community. Traditionally it has been linked to the presence of mantle plumes at depth (e.g. Hawaii), although the interaction with plate tectonics is also recognized to play a significant role (e.g. Azores, Galápagos). Magma compositions may range from basaltic to more differentiated...

The origin, evolution, and environmental impact of large igneous provinces (LIPs) represents a topic of high scientific importance because the magmatism associated with these features cannot be directly related to plate tectonics, and because the eruption of flood basalts may have global environmental consequences. Oceanic LIPs are even more poorly understood due to their relative inaccessibility. This volume takes a multidisciplinary approach to understanding LIP origin, evolution, and environmental impact in ocean basins. Papers that focus on plate tectonic reconstructions, petrologic and geophysical investigations of various LIPs, and sedimentological and micropaleontological evidence of syn-LIP sediments are presented. Precious materials and data from dredging cruises and scientific ocean drilling expeditions have made this volume possible.
A collection of documents supplementing the companion series known as "Colonial records of Pennsylvania" which contain the minutes of the Provincial Council, of the Council of Safety, and of the Supreme Executive Council of Pennsylvania.
Noisy Oceans Measuring devices such as ocean bottom seismometers and hydrophones designed to detect earthquakes pick up many other signals. These were previously ignored as background noise from unknown sources, but advanced technology now allows insights into the noise created from icebergs, ships, hydrothermal vents, whales, rain, marine engineering, and more. Noisy Oceans: Monitoring Seismic and Acoustic Signals in the Marine Environment is a comprehensive guide to non-tectonic marine noise originating from different environmental, biological, and anthropogenic sources. Volume highlights include: Overview of marine soundscapes and their sources Existing and new methods for studying acoustic signals Case studies from around the world Spans disciplines from geology and geophysicists to biology Explores the impacts and implications of marine noise The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity. Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals.
The most recent developments in diagnostic and therapeutic aspects of Gliomas (Glioblastoma) in the brain are presented. The importance of personalized medicine and clinical validation for targeted therapy are discussed. The identification of various types of biomarkers is included. The identification and validation of brain cancer (glioblastoma) genes are discussed. Role of cancer stem cells in the initiation, progression, and persistence of malignant gliomas is explained. The use of surgical resection, chemotherapy (e.g., temozolomide), immunotherapy, and radiotherapy for malignant glioblastoma are pointed out. Standard (established) as well as newer imaging modalities (proton magnetic resonance spectroscopy) are discussed.
Attaining the benefits of (especially fiscal) decentralization in government remains an enduring challenge, in part because the re-arrangement of public functions across levels of government has often been carried out poorly. This book aims to provide a firmer conceptual basis for the re-arrangement of public functions across levels of government. In doing so, it offers practical advice for policy makers from developing and emerging countries and development cooperation practitioners engaged in such activity. Combining a theoretical approach for inter-governmental functional assignment with an in-depth analysis of real-life country cases where functional assignment (FA) has been supported in...
Indonesia is currently facing some severe challenges, both in political affairs and in economic management. One of these challenges is the recently enacted decentralization program, now well underway, which promises to have some wide-ranging consequences. This edited volume presents original papers, written by a select group of widely recognized and distinguished scholars, that take a hard, objective look at the many effects of decentralization on economic and political issues in Indonesia. There are many questions about this program: how will it be implemented, is there capacity at the local level to implement its reforms, is there sufficient local political accountability to make it work, ...
The Negev desert occupies most of the territory of Israel. It has a strategic importance for the existence of the center of the country and at the same time is considered as a natural wild periphery. Since the 1920s, there was a tendency to conquer and flourish the desert, while since the 1980s, the ecological values gained importance. This manuscript reveals the relationship between man and his environment, employing texts analysis according to the ecocriticism approach. The study shows how as part of globalization processes, the status of collectivism in Israeli society was declined whereas the ability of social groups to influence the spatial identity construction has increased.
