This paper presents a method for classification of medical images, using machine learning and deformation-based morphometry. A morphological representation of the anatomy of interest is first obtained using highdimensional template warping, from which regions that display strong correlations between morphological measurements and the classification (clinical) variable are extracted using a watershed segmentation, taking into account the regional smoothness of the correlation map which is estimated by a crossvalidation strategy in order to achieve robustness to outliers. A Support Vector Machine-Recursive Feature Elimination (SVM-RFE) technique is then used to rank computed features from the extracted regions, according to their effect on the leave-one-out error bound. Finally, SVM classification is applied using the best set of features, and it is tested using leave-one-out. The results from a group of 61 brain images of female normal controls and schizophrenia patients demonstrate not only high classification accuracy (91.8%) and steep ROC curves, but also exceptional stability with respect to the number of selected features and the SVM kernel size
In sync with adolescence : The role of morningness-eveningness in development
At the start of every school day, it’s not an unfamiliar sight to see younger children bounding toward school, bright-eyed and bushy-tailed, ready to seize the day. In contrast, adolescents sometimes seem to sleepwalk toward their middle and high schools, often bleary-eyed, cantankerous, and less than enthusiastic to get down to work. Why the difference?
Hydrological and Biological Responses to Forest Practices : The Alsea Watershed Study
Through analyses of works generated by the study, Hydrological and Biological Responses to Forest Practices: The Alsea Watershed Study addresses the quantification of forest resource sustainability and bolsters the case for long-term monitoring at a time when managers and policy makers are searching for ways to restore the runs of salmon and steelhead to rivers and streams of the Pacific Northwest. Edited by John D. Stednick, a forest hydrologist responsible for the study’s reactivation, this book will be of interest to students in natural resources, land managers, policy makers, and researchers, particularly in water and fishery resources.
Habitats and Biota of the Gulf of Mexico : Before the deepwater horizon oil spill ; Vol.2 : Fish resources, fisheries, sea turtles, avian resources, marine mammals, diseases and mortalities
The Gulf of Mexico is an open and dynamic marine ecosystem rich in natural resources but heavily impacted by human activities, including agricultural, industrial, commercial and coastal development. Nutrients and pollutants from coastal communities and dozens of rivers flow into the Gulf, including material from the Mississippi River watershed, which drains over one third of continental United States. The Gulf of Mexico has been continuously exposed to petroleum hydrocarbons for millions of years from natural oil and gas seeps on the sea floor, and more recently from oil drilling and production activities located in the water near and far from shore. Major accidental oil spills in the Gulf are infrequent; two of the most significant include the Ixtoc I blowout in the Bay of Campeche in 1979 and the Deepwater Horizon Oil Spill in 2010.

Forest ecosystems and environments : Scaling up from shoot module to watershed
The Global Change Impacts on Terrestrial Ecosystems in Monsoon Asia (TEMA) project was carried out as a unique contribution to the international project Global Change and Terrestrial Ecosystems. TEMA aimed to integrate forest ecosystem processes. This volume presents the scaling-up concept for better understanding of ecosystem functioning.
Environmental Role of Wetlands in Headwaters
Internationally, the wetlands of headwater and upland regions provide many valuable environmental services. This book moves towards a more comprehensive inventory of the benefits and costs of headwater wetlands. It evaluates the research that tries to understand the tolerances, exchanges, checks and balances within headwater landscapes and the downstream impacts of changes in wetlands. It employs case studies and reviews from 21 nations spanning Europe, Africa, Asia and the Americas. It explores the new policy frameworks, changes in land husbandry, new systems for community education, participatory processes and technological interventions required for the effective management of headwater wetlands and the full integration of wetlands (including newly constructed wetlands) into environmental management and planning. In the past, most research dealt with wetlands as isolated features, this book examines wetlands in their watershed management context.
Management of Intentional and Accidental Water Pollution
The goals of the workshop included a discussion of the state of the science in identification of new research and approaches for water pollution events and communication of the management of water pollution and sustainability of water resources. Critical to management of accidental and intentional pollution events is the assessment of the risk, an understanding of the hazards and lessons learned from events which may lead to preventative management and control strategies. Public health protection will ultimately be improved by the ability to develop management frameworks which are flexible and adaptable to the specific region, country or watershed problems and concerns and allow for prioritization in the decision making. The integration of scientific information regarding the types of hazards the environmental fate of the chemical/biological, exposure pathways and human and ecosystem impacts may be implemented from both a qualitative or descriptive approach or using a more classical quantitative risk assessment paradigm. Thus the frameworks for assessing the risk and managing the risk may be seen as preventive, early warning and responsive.
Lives in Architecture : Terry Farrell
Offering a compelling personal account of his life in architecture as an influential postmodern designer, architect-planner and principal of a leading global practice, this autobiography includes anecdotes and invaluable insights into Terry’s life and work from the 1940s to the present day. An inside view of what it’s like to be an architect at the top of his profession, this book also highlights what it takes to develop a successful international practice. Offers the inside view of what it is like to be an architect at the top of his profession, including insights into the defining projects and watershed moments of Sir Terry Farrell's career Provides the inside story on some of Terry Farrell’s most significant buildings and projects, including Charing Cross Station, The MI6 Building, Alban Gate and Beijing South Railway Station. Abundantly illustrated with over 80 images, including personal photos and images of key buildings.
Landscape Pattern Analysis for Assessing Ecosystem Condition
Landscape Pattern Analysis for Assessing Ecosystem Condition presents a new method for assessing spatial pattern in raster land cover maps based on satellite imagery in a way that incorporates multiple pixel resolutions. This is combined with more conventional single-resolution measurements of spatial pattern and simple non-spatial land cover proportions to assess predictability of both surface water quality and ecological integrity within watersheds of the state of Pennsylvania (USA).
