Microphysics Of Atmospheric Phenomena

Download Microphysics Of Atmospheric Phenomena

This book investigates elementary processes in the Earth’s atmosphere involving photons, electrons, ions, radicals, and aerosols. It is based on global atmospheric models such as the standard atmospheric model with averaged atmospheric parameters across the globe and over time, the Earth’s energetic balance, and the global electric circuit that allows to analyze fundamental atmospheric properties to be analyzed. Rate constants of elementary processes in the Earth’s atmosphere, together with measured atmospheric parameters and existing concepts of atmospheric phenomena, are used in the analysis of global and local atmospheric processes. Atmospheric photoprocesses result from the interaction of solar radiation with the atmosphere and processes involving ions, oxygen atoms, excited atomic particles and ozone molecules. Atmospheric electricity as a secondary phenomenon to atmospheric water circulation results in a chain of processes that begins with collisions of water aerosols in different aggregate states. Cosmic rays are of importance for atmospheric electricity, as they create positive and negative ions in the air. Air breakdown in an electric field of clouds in the form of lightning may develop under the influence of cosmic ray-created seed electrons, which are necessary for electron multiplication in ionization wave-streamers. The upper atmosphere (ionosphere) is formed under solar radiation in a vacuum ultraviolet spectrum, and absorption of this radiation leads to air photoionization. The greenhouse effect is determined by atmospheric water, whereas transitions between a water vapor and aerosols may lead to a change in atmospheric optical depth. Carbon dioxide contributes in small portions to the atmospheric greenhouse effect. Cosmic rays are of importance for atmospheric discharge, the origin of lightning and cloud formation in the first stage of aerosol growth. This book provides a qualitative description of atmospheric properties and phenomena based on elementary processes and simple models.

Microbial Biomass: A Paradigm Shift In Terrestrial Biogeochemistry

by Kevin Russel Tate (Author)

Microbial Biomass informs readers of the ongoing global revolution in understanding soil and ecosystem processes. The first paper on the subject was written by David Jenkinson in 1966, and here new insights and expansions are given on the fascinating world of soil microbial processes. In terms of contemporary issues, it also serves to support urgent efforts to sustainably manage land to feed a growing world population without compromising the environment. It presents new methods of investigation which are leading to more sustainable management of ecosystems, and improved understanding of ecosystem changes in an increasingly warmer world.The book approaches the topic by looking at the emergence of our understanding of soil biological processes, and begins by tracing the conception and first measurement of soil microbial biomass. Following this, changes in ecosystems, and in natural ecosystem processes are discussed in relation to land management issues and global change. Microbial biomass and its diversity are recognized as key factors in finding solutions for more sustainable land and ecosystem management, aided by new molecular and other tools. Information from the use of these tools is now being incorporated into emerging microbial-explicit predictive models, to help us study changes in earth system processes.Perfect for use in research and practice, this book is written for undergraduate and graduate students, researchers and professionals of agronomy, chemistry, geology, physical geography, ecology, biology, microbiology, silviculture and soil science.

Understanding And Investigating Response Processes In Validation Research

Download Understanding And Investigating Response Processes In Validation Research

This volume addresses an urgent need across multiple disciplines to broaden our understanding and use of response processes evidence of test validity. It builds on the themes and findings of the volume Validity and Validation in Social, Behavioral, and Health Sciences (Zumbo & Chan, 2014), with a focus on measurement validity evidence based on response processes.

Approximately 1000 studies are published each year examining the validity of inferences made from tests and measures in the social, behavioural, and health sciences. The widely accepted Standards for Educational and Psychological Testing (1999, 2014) present five sources of evidence for validity: content-related, response processes, internal structure, relationships with other variables, and consequences of testing. Many studies focus on internal structure and relationships with other variables sources of evidence, which have a long history in validation research, known methodologies, and numerous exemplars in the literature. Far less is understood by test users and researchers conducting validation work about how to think about and apply new and emerging sources of validity evidence. This groundbreaking volume is the first to present conceptual models of response processes, methodological issues that arise in gathering response processes evidence, as well as applications and exemplars for providing response processes evidence in validation work.

Mapping Across Academia

This book addresses the role and importance of space in the respective fields of the social sciences and the humanities. It discusses how map representations and mapping processes can inform ongoing intellectual debates or open new avenues for scholarly inquiry within and across disciplines, including a wide array of significant developments in spatial processes, including the Internet, global positioning system (GPS), affordable digital photography and mobile technologies. Last but not least it reviews and assesses recent research challenges across disciplines that enhance our understanding of spatial processes and mapping at scales ranging from the molecular to the galactic.

Reconciliation And Social Healing In Afghanistan: A Transrational And Elicitive Analysis Towards Transformation

Download Reconciliation And Social Healing In Afghanistan: A Transrational And Elicitive Analysis Towards Transformation

Heela Najibullah analyzes the Afghan reconciliation processes through the lenses of transrational peace philosophy and Elicitive Conflict Transformation. The research highlights two Afghan governments reconciliation processes in 1986 and 2010 and underlines the political events that shaped the 1986 National Reconciliation Policy, drawing lessons for future processes. The author points out the historical and geopolitical patterns indicating regional and global stakeholders involvement in Afghan politics. Social healing through a middle-out approach is the missing and yet crucial component to achieve sustainable reconciliation in Afghanistan.
