Effective Risk Communication
by Robert Littlefield Robert R. Ulmer Matthew W. Seeger Timothy L. SellnowThe overlying purpose of this book is to construct a communication based approach to risk communication. In doing so, this book establishes a message-centered focus to risk communication. Section one of the book establishes definitions and parameters of risk communication, identifies the complex audience expectations for risk messages, and introduces a model of best practices for effective risk communication. In section two, the best practices are applied in four robust case studies. Section three includes chapters devoted to developing a mindful approach to risk communication, ethical considerations of risk communication, and a final chapter that discusses future developments of risk communication.
Effective Spacetime
by Karen CrowtherThis book discusses the notion that quantum gravity may represent the "breakdown" of spacetime at extremely high energy scales. If spacetime does not exist at the fundamental level, then it has to be considered "emergent", in other words an effective structure, valid at low energy scales. The author develops a conception of emergence appropriate to effective theories in physics, and shows how it applies (or could apply) in various approaches to quantum gravity, including condensed matter approaches, discrete approaches, and loop quantum gravity.
Effective Supply Mechanism and Path of Environmental Public Goods in China (Public Economy and Urban Governance in China)
by Jibo YangThis book, from the perspectives of the spatial and intergenerational externalities of environmental public goods, provides a comprehensive overview of the concepts and theories concerning environmental public goods supply and illustrates how to design the mechanism for promoting resident participation in effective environmental public goods supply under the guidance of the government. Noticeably, an intergenerational overlapping model for resident participation in environmental public goods supply has been created in the book, which generates new ideas for mitigating the long-standing forward intergenerational goods shortage. Moreover, this book uses happiness dataset to measure the feasibility of resident participation in environmental public goods supply and also makes a comparison between two supply models: Government Provide Model and Residents, Enterprises and Government Provide Model, so as to offer theoretically feasible suggestions.Not only is this book highly recommended for professionals in government units, universities, and research institutions that are engaged in environmental governance, but it can be used as a reference book for students of relevant majors in institutions of higher learning.

Effective Theories in Physics
by James D. WellsThere is significant interest in the Philosophy of Science community to understand the role that "effective theories" have in the work of forefront science. The ideas of effective theories have been implicit in science for a long time, but have only been articulated well in the last few decades. Since Wilson's renormalization group revolution in the early 1970's, the science community has come to more fully understand its power, and by the mid-1990's it had gained its apotheosis. It is still one of the most powerful concepts in science, which has direct impact in how one thinks about and formulates theories of nature. It is this power that this Brief sets out to emphasize through historical analysis and current examples.

Effective Tracking of Building Energy Use
by National Research Council Committee on National Statistics Division on Engineering and Physical Sciences Division of Behavioral and Social Sciences and Education William F. Eddy Krisztina Marton Board on Energy and Environmental Systems Panel on Redesigning the Commercial Buildings and Residential Energy Consumption Surveys of the Energy Information AdministrationThe United States is responsible for nearly one-fifth of the world's energy consumption. Population growth, and the associated growth in housing, commercial floor space, transportation, goods, and services is expected to cause a 0.7 percent annual increase in energy demand for the foreseeable future. The energy used by the commercial and residential sectors represents approximately 40 percent of the nation's total energy consumption, and the share of these two sectors is expected to increase in the future. The Commercial Buildings Energy Consumption Survey (CBECS) and Residential Energy Consumption Survey (RECS) are two major surveys conducted by the Energy Information Administration. The surveys are the most relevant sources of data available to researchers and policy makers on energy consumption in the commercial and residential sectors. Many of the design decisions and operational procedures for the CBECS and RECS were developed in the 1970s and 1980s, and resource limitations during much of the time since then have prevented EIA from making significant changes to the data collections. Effective Tracking of Building Energy Use makes recommendations for redesigning the surveys based on a review of evolving data user needs and an assessment of new developments in relevant survey methods.

Effective and Equitable Teacher Practice in Mathematics and Science Education: A Nordic Perspective Across Time and Groups of Students (IEA Research for Education #14)
by Trude Nilsen Kajsa Yang Hansen Nani TeigThis open access book presents original research on effective and equitable teacher practice in mathematics and science education across Nordic countries. It focuses on three key aspects of teacher practice: what teachers teach, how teachers teach, and how teachers assess their students.To provide a comprehensive understanding of teacher practice, data from the IEA’s Trends in Mathematics and Science Study (TIMSS) from 2011 to 2019 was analyzed. TIMSS provides large-scale and representative data, allowing an in-depth investigation of the relations between teachers, their practices, and student outcomes. The findings highlight the changes in teacher practice over time and the extent to which such changes explain the differences in student outcomes. This research also contributes to understanding how the relationships between teacher practice and student outcomes vary across different student groups (i.e., gender, socioeconomic status, and language background). The empirical evidence presented not only adds a significant layer to the academic discourse but also offers practical implications. These insights are crucial in facilitating educational policymaking and classroom practices aimed at improving student outcomes and closing gaps in educational inequality.
Effectiveness of Bank Filtration for Water Supply in Arid Climates (IHE Delft PhD Thesis Series)
by Ahmed Ragab MahmoudIn many developing countries, water demand is increasing while surface- and groundwater resources are threatened by pollution and overexploitation. Hence, a more sustainable approach to water resources management and water treatment is required. In this capacity, bank filtration is a natural treatment process that makes use of the storage and contaminant attenuation capacity of natural soil/rock. However, BF is site-specific and a significant knowledge gap exists regarding the design and management of bank filtration systems, particularly in developing countries. This research aimed to address these gaps and contribute to the transfer of bank filtration to developing countries. This study comprised both column and batch laboratory-scale experiments to determine the effect of environmental variables such as temperature, raw water organic composition and redox conditions on the removal of chemical pollutants such as organic matter, micro-pollutants and heavy metals as well as the mobility of iron, manganese and arsenic under anaerobic conditions. Ultimately, the effectiveness of BF for supplying high drinking water quality was assessed in a case study in Egypt. The study showed that more than 80% of biodegradable organic matter was removed during infiltration at temperatures between 20 and 30 °C. However, humic compounds enriched during BF, required post-treatment. Moreover, high humic content of infiltrating water reduced the removal of heavy metal and promoted the release of metal (loids) into the infiltrating water, rendering it more feasible to install BF wells within surface water systems with low levels of organic matter. Moderately-hydrophobic organic micropollutants were most persistent and required infiltration times longer than 30 days for complete elimination even at high temperatures (>20 °C). Finally, design parameters such as the number of infiltration wells should be configured to minimise the proportion of polluted groundwater in the pumped water. Overall, this study provides insight into the effectiveness of BF in removing chemical pollutants from surface water and proposes guidelines for the successful application of BF in developing countries where arid conditions and high temperatures prevail.

Effects of Anthropogenic Noise on Animals
by Arthur N. Popper Richard R. Fay Hans Slabbekoorn Robert J. DoolingOver the past several years, many investigators interested in the effects of man-made sounds on animals have come to realize that there is much to gain from studying the broader literature on hearing sound and the effects of sound as well as data from the effects on humans. It has also become clear that knowledge of the effects of sound on one group of animals (e.g., birds or frogs) can guide studies on other groups (e.g., marine mammals or fishes) and that a review of all such studies together would be very useful to get a better understanding of the general principles and underlying cochlear and cognitive mechanisms that explain damage, disturbance, and deterrence across taxa.The purpose of this volume, then, is to provide a comprehensive review of the effects of man-made sounds on animals, with the goal of fulfilling two major needs. First, it was thought to be important to bring together data on sound and bioacoustics that have implications across all taxa (including humans) so that such information is generally available to the community of scholars interested in the effects of sound. This is done in Chaps. 2-5. Second, in Chaps. 6-10, the volume brings together what is known about the effects of sound on diverse vertebrate taxa so that investigators with interests in specific groups can learn from the data and experimental approaches from other species. Put another way, having an overview of the similarities and discrepancies among various animal groups and insight into the “how and why” will benefit the overall conceptual understanding, applications in society, and all future research.
Effects of Electromagnetic Radiation on Living Beings
by Felix A. FarretThe objective of this book is to show in detail how electromagnetic waves existing in the environment can affect the electrochemical currents present in the brains and bodies of living beings that serve to communicate with their internal organs as well as with other living beings. These electromagnetic waves are distributed intensively by current means of communication (television, cell phones, radar, medical equipment, electrical machines, electrical networks, etc.) and by the stars in the Universe. Such waves can affect in one way or another the electrochemical currents of living beings, which seem to be currently interpreted as sensations, hypnosis, telepathy, intuition, spells, mediumship, visions and precognition, as well as other less widespread forms, such as telekinesis, radiesthesia, clairvoyance, precognition and teleportation. Several world-famous examples of these possibilities are illustrated in the final chapter of this book.Key Features: 14 examples of diverse international case studies included Challenges conventional ways of thinking by exploring the intersection of electromagnetic waves and extrasensory perception Equips readers with insights into the various effects of electromagnetic waves in daily life, which promotes awareness of their environment and its different influences and how they impact people Provides an engineering framework for understanding extrasensory beliefs and aims to explain the concept of historical brain believing in a better manner

Effects of Non-locality in Gravity and Quantum Theory (Springer Theses)
by Jens BoosThis thesis is devoted to the systematic study of non-local theories that respect Lorentz invariance and are devoid of new, unphysical degrees of freedom. Such theories are attractive for phenomenological applications since they are mostly unconstrained by current experiments. Non-locality has played an increasingly important role in the physics of the last decades, appearing in effective actions in quantum field theory, and arising naturally in string theory and non-commutative geometry. It may even be a necessary ingredient for quantum theories of gravity. It is a feature of quantum entanglement, and may even solve the long-standing black hole information loss problem. “Non-locality” is a broad concept with many promising and fruitful applications in theoretical and mathematical physics. After a historical and pedagogical introduction into the concept of non-locality the author develops the notion of non-local Green functions to study various non-local weak-field problems in quantum mechanics, quantum field theory, gravity, and quantum field theory in curved spacetime. This thesis fills a gap in the literature by providing a self-contained exploration of weak-field effects in non-local theories, thereby establishing a “non-local intuition” which may serve as a stepping stone for studies of the full, non-linear problem of non-locality.
Effects of Opera Music from Brain to Body: A Matter of Wellbeing (Neurocultural Health and Wellbeing)
by Lorenzo Lorusso Michele Augusto Riva Vittorio Alessandro SironiThis book explores the connection between melodrama and medicine from multiple perspectives. Neuroscientists study the relationship between opera and brain functioning in the light of new findings in the fields of neurophysiology, neuroimaging, cognitive science and neuro-musicology; clinicians investigate the therapeutic potential of music, especially in the field of treatment and rehabilitation of individuals with neurodegenerative diseases; medical historians analyse the representation of diseases and those who cure diseases within operas; occupational doctors report descriptions of diseases that affect workers in the opera world and particularly focus on psychiatric and psychological alterations. Opera, with its instrumental and vocal accompaniment, is considered the most complete form of theatrical performance. However, little is known about the mechanisms of brain activity under the influence of melodrama on singers, musicians, and listeners. The use of neuroimaging techniques has enabled a better understanding of the neuronal mechanisms and circuits involved during an opera performance. Over the past 20 years, melodrama has increasingly been used as a therapeutic approach in various neurological and neuropsychiatric pathologies, such as depression, cognitive impairment, and even coma. The book also discusses the ways in which melodrama affects professionals involved in music and interventions to reduce or alleviate occupational diseases, leading to improved health and higher life satisfaction. The ultimate goal is to improve therapeutic interventions in neurological diseases and professional disorders, relying on solid neuroscientific data. This book will be of great interest to neurologists, neurobiologists, psychiatrists, occupational doctors and therapists in music.

Effects of Wetland Conversion to Farming on Water Quality and Sediment and Nutrient Retention in a Tropical Catchment (IHE Delft PhD Thesis Series)
by Abias UwimanaThe study used a combination of landscape-scale synoptic surveys (catchment, reaches) and mesocosm surveys (experimental plots) to assess the impacts of conversion of natural valley-bottom wetlands to farming land on the water quality and retention of sediment and nutrients. The results showed that temperature, pH, electrical conductivity and dissolved oxygen concentration decreased, and total suspended solids (TSS) increased with storm water increase. Nitrogen (TN) and phosphorus (TP) accumulated in the catchment during the dry season and washed into the water courses during the early stages of the higher flows, with subsequent lower concentrations at the end of the rains due to dilution. Large proportions of the annual loads of TSS, TP and TN (93%, 60% and 67%, respectively) were transported during rainfall events that occurred in 115 days. Fishponds acted as temporal traps of TSS, TN and TP at the early stages of farming, and were a source of and TN and TP at the end of the farming period, in contrast to rice farming that generated sediments and nutrients early in the farming period and trapped them at the end of the farming season. Wetlands mostly acted as sinks but sometimes as a source of sediment and nutrients.
