Recognize and promote exceptional teaching based on how students learn! To improve teaching, school leaders must understand how students learn. Authors P. Karen Murphy and Patricia Alexander explore key psychological dimensions of learners and explain how these dimensions can be incorporated into more effective teaching strategies. Their accessible overview of classic and current educational research is part of the Leadership for Learning initiative of the American Association of School Administrators (AASA). Understanding How Students Learn provides guiding principles that school leaders can use to help their teachers develop a learner-centered approach to instruction that enables all students to learn at high levels and do well on common measures of academic achievement. Concepts explored in-depth include: Learner growth and development Acquiring knowledge and understanding Cultivating learner motivation Strategic teaching and strategic learning The power of shared learning In addition to outlining specific guidelines for research-based action, the authors provide leaders with an understanding of student learning that empowers them to work more productively with teachers, parents, community leaders, and students. Designed for principals and school administrators who have assumed the role of instructional leader, this book will also be an invaluable resource for those contemplating a career in school administration or teachers concerned with improving academic performance.
The book provides an up-to-date account of the neuropsychological, cognitive-neurological, and neuropsychiatric aspects of movement disorders. The past ten years have seen an explosion of research covering non-motor aspects of Parkinson's disease and, more recently, movement disorders such as essential tremor, dystonia, corticobasal syndrome, progressive supranuclear palsy, and multiple system atrophy. It is often these neurobehavioral features that become troubling to the patient: they are sometimes difficult to recognize and treat, are associated with diminished patient and caregiver quality of life, and may hasten disease progression, loss of independence, and institutionalization. This book discusses the most recent diagnostic and treatment guidelines for such cognitive and psychiatric conditions in Parkinson's disease and other movement disorders, while providing practical tips and strategies for general assessment. The rapid accumulation of research in this field makes it increasingly difficult for one or two people to author a comprehensive text in an expert manner. The world-class team assembled for this volume succeeds in covering widely diverse areas such as the pathology, neuroimaging, assessment, and treatment of an ever-growing set of neurobehavioral features of movement disorders -- cognitive impairment and dementia, depression, apathy, anxiety, psychosis, and impulse control disorders. The text also surveys fundamental knowledge about basal ganglia function and dysfunction, assessment and evaluation techniques applicable to a range of movement disorders, and quality of life issues more broadly.
This book gives a concise introduction to Quantum Mechanics with a systematic, coherent, and in-depth explanation of related mathematical methods from the scattering theory and the theory of Partial Differential Equations.The book is aimed at graduate and advanced undergraduate students in mathematics, physics, and chemistry, as well as at the readers specializing in quantum mechanics, theoretical physics and quantum chemistry, and applications to solid state physics, optics, superconductivity, and quantum and high-frequency electronic devices.The book utilizes elementary mathematical derivations. The presentation assumes only basic knowledge of the origin of Hamiltonian mechanics, Maxwell equations, calculus, Ordinary Differential Equations and basic PDEs. Key topics include the Schrödinger, Pauli, and Dirac equations, the corresponding conservation laws, spin, the hydrogen spectrum, and the Zeeman effect, scattering of light and particles, photoelectric effect, electron diffraction, and relations of quantum postulates with attractors of nonlinear Hamiltonian PDEs. Featuring problem sets and accompanied by extensive contemporary and historical references, this book could be used for the course on Quantum Mechanics and is also suitable for individual study.
At 14,259 feet, Longs Peak towers over Colorado’s northern Front Range. A prized location for mountaineering since the 1870s, Longs has been a place of astonishing climbing feats—and, unsurprisingly, of significant risk and harm. Careless and unlucky climbers have experienced serious injury and death on the peak, while their activities, equipment, and trash have damaged fragile alpine resources. As a site of outdoor adventure attracting mostly white people, Longs has mirrored the United States’ tenacious racial divides, even into the twenty-first century. In telling the history of Longs Peak and its climbers, Ruth M. Alexander shows how Rocky Mountain National Park, like the National Park Service (NPS), has struggled to contend with three fundamental obligations—to facilitate visitor enjoyment, protect natural resources, and manage the park as a site of democracy. Too often, it has treated these obligations as competing rather than complementary commitments, reflecting national discord over their meaning and value. Yet the history of Longs also shows us how, over time, climbers, the park, and the NPS have attempted to align these obligations in policy and practice. By putting mountain climbers and their relationship to Longs Peak and its rangers at the center of the story of Rocky Mountain National Park, Alexander exposes the significant role outdoor recreationists have had—as both citizens and privileged adventurers—in shaping the peak’s meaning, use, and management. Since 2000, the park has promoted climber enjoyment and safety, helped preserve the environment, facilitated tribal connections to the park, and attracted a more diverse group of visitors and climbers. Yet, Alexander argues, more work needs to be done. Alexander’s nuanced account of Longs Peak reveals the dangers of undermining national parks’ fundamental obligations and presents a powerful appeal to meet them fairly and fully.
This book opens a new avenue to an engendering field of applied physics, located at the “crossing” of modern photonics, electromagnetics, acoustics and material science. It also highlights the concept of “non-locality”, which proves to be not a special feature of quantum phenomena, but is shown to have an important counterpart in classical physics and its engineering applications too. Furthermore, it visualizes the physical results by means of simple analytical presentations, reduced sometimes to the elementary functions.
The focus of the present work is nonrelativistic and relativistic quantum mechanics with standard applications to the hydrogen atom. The author has aimed at presenting quantum mechanics in a comprehensive yet accessible for mathematicians and other non-physicists. The genesis of quantum mechanics, its applications to basic quantum phenomena, and detailed explanations of the corresponding mathematical methods are presented. The exposition is formalized (whenever possible) on the basis of the coupled Schroedinger, Dirac and Maxwell equations. Aimed at upper graduate and graduate students in mathematical and physical science studies.
In this monograph, the authors present their recently developed theory of electromagnetic interactions. This neoclassical approach extends the classical electromagnetic theory down to atomic scales and allows the explanation of various non-classical phenomena in the same framework. While the classical Maxwell–Lorentz electromagnetism theory succeeds in describing the physical reality at macroscopic scales, it struggles at atomic scales. Here, quantum mechanics traditionally takes over to describe non-classical phenomena such as the hydrogen spectrum and de Broglie waves. By means of modifying the classical theory, the approach presented here is able to consistently explain quantum-mechanical effects, and while similar to quantum mechanics in some respects, this neoclassical theory also differs markedly from it. In particular, the newly developed framework omits probabilistic interpretations of the wave function and features a new fundamental spatial scale which, at the size of the free electron, is much larger than the classical electron radius and is relevant to plasmonics and emission physics. This book will appeal to researchers interested in advanced aspects of electromagnetic theory. Treating the classical approach in detail, including non-relativistic aspects and the Lagrangian framework, and comparing the neoclassical theory with quantum mechanics and the de Broglie–Bohm theory, this work is completely self-contained.
This book, on the basis of a generalization and critical analysis of materials on constructed concrete dams, accumulated experience in their operation, and current trends, considers a set of problems associated with the design and construction of concrete dams. The modern principles of designing gravity and arch dams and the main provisions of the calculation justification of their reliability in comparison with US standards are outlined. Great attention has been paid to rolled concrete dams, taking into account their specific characteristics. Ways of increasing the efficiency of dams through the improvement of layout and structural solutions, calculation methods, and a more complete consideration of the features of natural conditions are considered. The book presents and analyzes the designs of erected concrete dams, which allows for a better understanding of the approaches and decision-making principles for designing dams, taking into account the specifics of natural, construction, and other conditions, and also analyzes a number of new solutions that reflect the various ways that engineering theory and practice has sought further improvement of concrete dams. This work will be useful to hydraulic engineers and professionals involved in the design, construction, and operation of concrete dams, as well as in settlement studies. The book will also be of interest to academics and can be used as a textbook by university students specializing in hydraulic engineering.
The Bellman function, a powerful tool originating in control theory, can be used successfully in a large class of difficult harmonic analysis problems and has produced some notable results over the last thirty years. This book by two leading experts is the first devoted to the Bellman function method and its applications to various topics in probability and harmonic analysis. Beginning with basic concepts, the theory is introduced step-by-step starting with many examples of gradually increasing sophistication, culminating with Calderón–Zygmund operators and end-point estimates. All necessary techniques are explained in generality, making this book accessible to readers without specialized training in non-linear PDEs or stochastic optimal control. Graduate students and researchers in harmonic analysis, PDEs, functional analysis, and probability will find this to be an incisive reference, and can use it as the basis of a graduate course.
This book describes in detail a method of direct optimization, which makes it possible to choose the best trajectory of an aircraft in conditions of its limited resource. This can happen in the event of an emergency on board, associated with both a possible equipment failure and external influences, for example, when lightning strikes an aircraft or collides with a moving object. The highlight of this book is the fact that the results presented in it can be applied universally to the choice of the flight path of large and small aircraft, as well as helicopter technology. In addition, they take into account various conditions of aircraft flight, including a possible accident. The methods and algorithms presented here can be used as the basis for the creation of automatic collision avoidance systems, as well as the choice of the best aircraft trajectory for flights in different regions and in different conditions.
The use of biologics – drugs made from living organisms – has raised specific scientific, industrial, medical and legal issues. The essays contained in this collection each deal with a case study of a biologic substance, or group of biologics, and its use during the twentieth century.
This is the first book on the U.S. presidential election system to analyze the basic principles underlying the design of the existing system and those at the heart of competing proposals for improving the system. The book discusses how the use of some election rules embedded in the U.S. Constitution and in the Presidential Succession Act may cause skewed or weird election outcomes and election stalemates. The book argues that the act may not cover some rare though possible situations which the Twentieth Amendment authorizes Congress to address. Also, the book questions the constitutionality of the National Popular Vote Plan to introduce a direct popular presidential election de facto, without amending the Constitution, and addresses the plan’s “Achilles’ Heel.” In particular, the book shows that the plan may violate the Equal Protection Clause from the Fourteenth Amendment of the Constitution. Numerical examples are provided to show that the counterintuitive claims of the NPV originators and proponents that the plan will encourage presidential candidates to “chase” every vote in every state do not have any grounds. Finally, the book proposes a plan for improving the election system by combining at the national level the “one state, one vote” principle – embedded in the Constitution – and the “one person, one vote” principle. Under this plan no state loses its current Electoral College benefits while all the states gain more attention of presidential candidates.
This book deals with diffraction radiation, which implies the boundary problems of electromagnetic radiation theory. Diffraction radiation is generated when a charged particle moves near a target edge at a distance ( – Lorentz factor, – wave length). Diffraction radiation of non-relativistic particles is widely used to design intense emitters in the cm wavelength range. Diffraction radiation from relativistic charged particles is important for noninvasive beam diagnostics and design of free electron lasers based on Smith-Purcell radiation which is diffraction radiation from periodic structures. Different analytical models of diffraction radiation and results of recent experimental studies are presented in this book. The book may also serve as guide to classical electrodynamics applications in beam physics and electrodynamics. It can be of great use for young researchers to develop skills and for experienced scientists to obtain new results.
This research monograph provides a brief overview of the authors' research in the area of ordered granular media over the last decade. The exposition covers one-dimensional homogeneous and dimer chains in great detail incorporating novel analytical tools and experimental results supporting the analytical and numerical studies. The proposed analytical tools have since been successfully implemented in studying two-dimensional dimers, granular dimers on on-site perturbations, solitary waves in Toda lattices to name a few. The second part of the monograph dwells on weakly coupled homogeneous granular chains from analytical, numerical and experimental perspective exploring the interesting phenomenon of Landau-Zener tunneling in granular media. The final part of the monograph provides a brief introduction to locally resonant acoustic metamaterials incorporating internal rotators and the resulting energy channeling mechanism in unit-cells and in one- and two-dimensional lattices. The monograph provides a comprehensive overview of the research in this interesting domain. However, this exposition is not all exhaustive with regard to equally exciting research by other researchers across the globe, but we provide an exhaustive list of references for the interested readers to further explore in this direction.
The work is aimed at the review of hot topics in modern light scattering and radiative transfer. A special attention will be given to the description of the methods of integro-differential radiative transfer equation solution. In particular, the asymptotic radiative transfer and the method of discrete ordinates will be considered. A comprehensive review of light absorption in the terrestrial atmosphere will be given as well. The inverse problem solution will be reviewed as well.
This book presents the first detailed account of Werner Heisenberg’s failed attempt to find a theory of everything in the autumn of his career. It further investigates what we can learn from his failure in relation to the search for a final theory of physics, an endeavour that continues to define research in fundamental physics to this day. Thereby it provides the first historically informed contribution to the current debate on post-empirical physics and the state of particle physics.
Molecules containing radioactive nuclei are discussed in detail in this work aiming at their usage as tracers for nucleosynthesis processes in the present star generation. So far, these processes can be observed in the Îł-ray region via the decay of the radioactive atom. The spatial resolution of the astronomical observations is low in most cases. Here, it is proposed that precise stellar positions in the sky can be achieved using low energetic photons, emitted from molecular rotational or ro-vibrational motion. The aim of this thesis is to derive the rotational fingerprints of diatomic astrophysical relevant radioactive molecules from laboratory measurements of their stable counterparts. In case of diatomic molecules this goal can be achieved by a mass-independent Dunham approach. This method has been successfully applied to reveal the spectra of the radioactive, long-lived species 26AIF, 26AlH, 26AlO, 26AlS, 32SiO, 44TiO, and 60FeO.
Alex Lord, a pioneer inspector of rural BC schools shares in these recollections his experiences in a province barely out of the stage coach era. Travelling through vast northern territory, utilizing unreliable transportation, and enduring climatic extremes, Lord became familiar with the aspirations of remote communities and their faith in the humanizing effects of tiny assisted schools. En route, he performed in resolute yet imaginative fashion the supervisory functions of a top government educator, developing an educational philosophy of his own based on an understanding of the provincial geography, a reverence for citizenship, and a work ethic tuned to challenge and accomplishment. Although not completed, these memoires invite the reader to experience the British Columbia that Alex Lord knew. Through his words, we endure the difficulties of travel in this mountainous province. We meet many of the unusual characters who inhabited this last frontier and learn of their hopes, fears, joys, sorrows, and eccentricities. More particularly, we are reminded of the historical significance of the one-room rural school and its role as an indispensable instrument of community cohesion. John Calam has organized the memoirs according to the regions through which Lord travelled. He has included in his introduction a biography of Alex Lord, a brief description of the British Columbia he knew, a sketch of its public education system, and an assessment of the place Lord’s writing now occupies among other works on education and society.
Random walks often provide the underlying mesoscopic mechanism for transport phenomena in physics, chemistry and biology. In particular, anomalous transport in branched structures has attracted considerable attention. Combs are simple caricatures of various types of natural branched structures that belong to the category of loopless graphs. The comb model was introduced to understand anomalous transport in percolation clusters. Comb-like models have been widely adopted to describe kinetic processes in various experimental applications in medical physics and biophysics, chemistry of polymers, semiconductors, and many other interdisciplinary applications.The authors present a random walk description of the transport in specific comb geometries, ranging from simple random walks on comb structures, which provide a geometrical explanation of anomalous diffusion, to more complex types of random walks, such as non-Markovian continuous-time random walks. The simplicity of comb models allows to perform a rigorous analysis and to obtain exact analytical results for various types of random walks and reaction-transport processes.
This book starts with an introduction to the basic concepts of multistability, then illustrates how multistability arises in different systems and explains the main mechanisms of multistability emergence. A special attention is given to noise which can convert a multistable deterministic system to a monostable stochastic one. Furthermore, the most important applications of multistability in different areas of science, engineering and technology are given attention throughout the book, including electronic circuits, lasers, secure communication, and human perception. The book aims to provide a first approach to multistability for readers, who are interested in understanding its fundamental concepts and applications in several fields. This book will be useful not only to researchers and engineers focusing on interdisciplinary studies, but also to graduate students and technicians. Both theoreticians and experimentalists will rely on it, in fields ranging from mathematics and laser physics to neuroscience and astronomy. The book is intended to fill a gap in the literature, to stimulate new discussions and bring some fundamental issues to a deeper level of understanding of the mechanisms underlying self-organization of matter and world complexity.
This book introduces systematically the operator method for the solution of the Schrödinger equation. This method permits to describe the states of quantum systems in the entire range of parameters of Hamiltonian with a predefined accuracy. The operator method is unique compared with other non-perturbative methods due to its ability to deliver in zeroth approximation the uniformly suitable estimate for both ground and excited states of quantum system. The method has been generalized for the application to quantum statistics and quantum field theory. In this book, the numerous applications of operator method for various physical systems are demonstrated. Simple models are used to illustrate the basic principles of the method which are further used for the solution of complex problems of quantum theory for many-particle systems. The results obtained are supplemented by numerical calculations, presented as tables and figures.
Almost 100 years have passed since Trautz and Lewis put forward their collision theory of molecular processes. Today, knowledge of molecular collisions forms a key part of predicting and understanding chemical reactions. This book begins by setting out the classical and quantum theories of atom-atom collisions. Experimentally observable aspects of the scattering processes; their relationship to reaction rate constants and the experimental methods used to determine them are described. The quantum mechanical theory of reactive scattering is presented and related to experimental observables. The role of lasers in the measurement and analysis of reactive molecular collisions is also discussed. Written with postgraduates and newcomers to the field in mind, mathematics is kept to a minimum, and readers are guided to appendices and further reading to gain a deeper understanding of the mathematics involved.
This monograph is a literary study of Lycophron's Alexandra, whose obscurity, a quality notorious already in antiquity, has long hampered holistic approaches. Through a series of distinct but closely integrated literary studies of major aspects of the poem, including its style, its engagement with the traditions of epic and tragedy, and it's treatment of heroism and of the gods, the book explores the way the Alexandra reconfigures Greek mythology. In particular, as it is presented in Homeric epic and Athenian tragedy, in order to cast the Romans and their restoration of Trojan glory as the ultimate telos of history. In this sense, the poem emerges as an important intermediary between Homeric epic and Latin poetry, particularly Vergil's Aeneid. By rewriting specific features of the epic and tragic traditions, the Alexandra denies to Greek heroes the glory that was the traditional compensation for their suffering, while at the same time attributing to Cassandra's Trojan family honours framed in the traditional language of Greek heroism. In this sense, the figure of Cassandra, a prophetess traditionally gifted with the power of foresight but denied credibility, self-reflexively serves as a vehicle for exploring the potentials and limitations of poetry.
