Carbon is a fundamental component of all life and its gaseous form, carbon dioxide (CO2), is an important atmospheric regulator of Earth’s climate. Over societally relevant timescales, diverse physical, biological, and chemical processes in the global ocean have a very important role in controlling the exchanges of CO2 with the atmosphere and climate, given that the ocean contains roughly 60 times more carbon than the atmosphere. The complex and dynamic marine carbon cycle is thus a fundamental part and regulator of life on Earth, requiring monitoring of its variability and understanding of the feedbacks to the climate system. This is particularly relevant given that emissions of human produced (anthropogenic) CO2 through fossil fuel and land use changes have led to significant perturbations in the global carbon cycle. A large fraction of emitted anthropogenic carbon (Cant) has been and will be absorbed by the oceans with implications for seawater chemistry, ocean pH levels, and the biological communities contained within. During the last few decades, quantification of the ocean sink of CO2 and its temporal evolution of the marine carbon cycle has been an important driver of marine biogeochemical research. Scientific expeditions such as the World Ocean Circulation Experiment/Joint Global Ocean Flux Study global surveys conducted during the 1990s provided the data for the first global estimates of the uptake and oceanic sink of Cant. More recently, completion of a second global survey of the marine carbon cycle (from 2000 to 2013) provided sufficient data to assess the rate of uptake and storage of Cant within the interior of the global ocean. From this effort, it has become clear that there is substantial regional and temporal variability of the storage rate of Cant and those physico-biogeochemical processes that influence the marine carbon cycle. Here we review seawater carbonate chemistry, the sampling strategies, and networks required to observe variability in the global ocean carbon cycle and the flux of carbon between the ocean and the atmosphere but with a central focus, synthesizing and summarizing available estimates of the ocean uptake and inventories of Cant. This chapter is aimed at a wider audience within the oceanographic community and points to the rich literature on marine carbon cycle research.
Progress in genetic knowledge is profoundly affecting medical practice, and no clinical specialty has more diseases associated with genetic mutations than neurology. As a more complete picture of the genes which give rise to neurological disease is obtained, trainee and practising neurologists need a guide to basic principles and the more important clinical entities with a genetic component. It is against this background that Neurogenetics: A Guide for Clinicians has been written. The book opens with coverage of genetic testing and counselling. Subsequent chapters discuss genetic factors for all the major neurological diseases, including epilepsy, Alzheimer's disease, Parkinsonism and muscular dystrophies. No book in this field can hope to be fully up to date with the latest research; rather this work provides a framework on which to add new genetic discoveries. Neurogenetics: A Guide for Clinicians provides a synoptic overview for neurologists, medical geneticists and scientists working in the field.
It is widely acknowledged that today’s teachers are tasked with educating increasingly diverse students as well as addressing their academic and social-emotional needs. This book examines cutting-edge teaching practices that make a difference in improving general educator and/or student performance across the grade spans. The emphasis is placed on research-based strategies, practices, and theories that can be readily translated into classroom practice. From Head to Heart: High Quality Teaching Practices in the Spotlight considers the importance of more personal topics within the teaching field, such as teacher wellness, as well as including information on effective teaching practices that seek to inspire and empower students and teachers. This book will be of interest to those that work within a pedagogical environment as well as university students and parents, alike.
Forensic archaeology is mostly defined as the use of archaeological methods and principles within a legal context. However, such a definition only covers one aspect of forensic archaeology and misses the full potential this discipline has to offer. This volume is unique in that it contains 57 chapters from experienced forensic archaeological practitioners working in different countries, intergovernmental organisations or NGO’s. It shows that the practice of forensic archaeology varies worldwide as a result of diverse historical, educational, legal and judicial backgrounds. The chapters in this volume will be an invaluable reference to (forensic) archaeologists, forensic anthropologists, humanitarian and human rights workers, forensic scientists, police officers, professionals working in criminal justice systems and all other individuals who are interested in the potential forensic archaeology has to offer at scenes of crime or places of incident. This volume promotes the development of forensic archaeology worldwide. In addition, it proposes an interpretative framework that is grounded in archaeological theory and methodology, integrating affiliated behavioural and forensic sciences.
Comprised of chapters written by established Canadian curriculum scholars as well as junior scholars and graduate students, this collection of essays provoke readers to imagine the different ways in which educational researchers can engage the narrative inquiry within the broader field of curriculum studies.
Includes over 50 photos and 23 maps. THIS IS THE first volume of a planned series dealing with United States Marine Operations in Korea during the period 2 August 1950 to 27 July 1953. Volume I is designed to give the military student and the casual reader an accurate and detailed account of the operations in which Marines of the 1st Provisional Brigade and Marine Air Group 33 participated during the fighting in the Pusan Perimeter, from the date of their landing on 2 August until their withdrawal on 13 September 1950, in preparation for the Inchon landing. “AN ABILITY TO furnish skilled forces to meet emergency situations on short notice has long been a hallmark of the Marine Corps. When the call came for such a force to be dispatched to Korea on 2 July 1950, the Corps was handicapped by the strictures of a peacetime economy. Nevertheless, a composite brigade consisting of a regiment and an air group was made available within a week’s time. With a reputation built largely on amphibious warfare, Marines of the 1st Brigade were called upon to prove their versatility in sustained ground action. On three separate occasions within the embattled Perimeter—south toward Sachon and twice along the Naktong River—these Marine units hurled the weight of their assault force at the enemy. All three attacks were successful, and at no point did Marines give ground except as ordered. The quality of their performance in the difficult days of the Pusan Perimeter fighting made them a valuable member of the United Nations team and earned new laurels for their Corps.”- Gen. Lemuel Shepherd.
