This book was released on 1999-11-17 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: In his 1997 State of the Union address, President Clinton announced a federal initiative to develop tests of 4th-grade reading and 8th-grade mathematics that could be administered on a voluntary basis by states and school districts beginning in spring 1999. The principal purpose of the Voluntary National Tests (VNT) is to provide parents and teachers with systematic and reliable information about the verbal and quantitative skills that students have achieved at two key points in their educational careers. The U.S. Department of Education anticipated that this information would serve as a catalyst for continued school improvement, by focusing parental and community attention on achievement and by providing an additional tool to hold school systems accountable for their students' performance in relation to nationwide standards. Shortly after initial development work on the VNT, Congress transferred responsibility for VNT policies, direction, and guidelines from the department to the National Assessment Governing Board (NAGB, the governing body for the National Assessment of Educational Progress). Test development activities were to continue, but Congress prohibited pilot and field testing and operational use of the VNT pending further consideration. At the same time, Congress called on the National Research Council (NRC) to assess the VNT development activities. Since the evaluation began, the NRC has issued three reports on VNT development: an interim and final report on the first year's work and an interim report earlier on this second year's work. This final report includes the findings and recommendations from the interim report, modified by new information and analysis, and presents our overall conclusions and recommendations regarding the VNT.

Book excerpt: In his 1997 State of the Union address, President Clinton announced a federal initiative to develop tests of 4th-grade reading and 8th-grade mathematics that would provide reliable information about student performance at two key points in their educational careers. According to the U.S. Department of Education, the Voluntary National Tests (VNT) would create a catalyst for continued school improvement by focusing parental and community-wide attention on achievement and would become new tools to hold school systems accountable for their students' performance. The National Assessment Governing Board (NAGB) has responsibility for development of the VNT. Congress recognized that a testing program of the scale and magnitude of the VNT initiative raises many important technical questions and requires quality control throughout development and implementation. In P.L. 105-78, Congress called on the National Research Council (NRC) to evaluate a series of technical issues pertaining to the validity of test items, the validity of proposed links between the VNT and the National Assessment of Educational Progress (NAEP), plans for the accommodation and inclusion of students with disabilities and English-language learners, plans for reporting test information to parents and the public, and potential uses of the tests. This report covers phase 1 of the evaluation (November 1997-July 1998) and focuses on three principal issues: test specifications and frameworks; preliminary evidence of the quality of test items; and plans for the pilot and field test studies, for inclusion and accommodation, and for reporting VNT results.

Download or read book Transcellular Cycles underlying Neurotransmission written by Sebastian Cerdan and published by Frontiers Media SA. This book was released on 2015-10-12 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: Synaptic transmission demands the operation of a highly specialized metabolic machinery involving the transfer of metabolites and neurotransmitters between neurons, astrocytes and microvessels. In the last years, important advances have occurred in our understanding of the mechanisms underlying cerebral activation, neuroglial coupling and the associated neurovascular response. Briefly, exacerbated oxygen consumption in stimulated neurons is thought to trigger glycolytic lactate and glucose transfer from astrocytes which, in turn, obtain these fuels from the microvasculature. Neurotransmitter release is made possible by a combination of transcellular cycles exchanging metabolites between these three compartments, returning eventually the synapsis to its pre-firing situation in the resting periods. In spite of the enormous progresses achieved in recent years, the drivers determining the predominant direction of the fluxes, their quantitative contribution and their energy requirements, have remained until today incompletely understood, more particularly under the circumstances prevailing in vivo. In many instances, progress derived from the implementation of novel methodological approaches including advanced neuroimaging and neurospectroscopy methods. As a consequence, literature in the field became vast, diverse and spread within journals of different specialities. The e-book "Transcellular cycles underlying neurotransmission" aims to summaryze in a single volume, recent progress achieved in hypothesis, methods and interpretations on the trafficking of metabolites between neurons and glial cells, and the associated mechanisms of neurovascular coupling.

Download or read book Spatial Econometrics Spatial Autoregressive Models written by Lung-fei Lee and published by World Scientific. This book was released on 2023-10-16 with total page 894 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the most recently developed book in Spatial Econometrics which cover important models and estimation methods. Its coverage is rather broad, and some of the topics covered have only been developed in the recent econometric literature in spatial econometrics.The book summarizes our devoted efforts on spatial econometrics that represent joint contributions with former PhD advisees from the Ohio State University in Columbus, Ohio, USA.The coverage is comprehensive and there are a total of sixteen chapters from basic statistics and statistical theory of linear-quadratic forms, law of large numbers (LLN) and central limit theory (CLT) on martingales to nonlinear spatial mixing and spatial near-epoch dependence theories, which can justify the statistic inferences for various spatial models and their estimation. New estimation and testing approaches in empirical likelihood and general empirical likelihood, and Bootstrapping are presented. Model selection is also discussed in this book. In addition to the popular spatial autoregressive models, there are chapters on multivariate SAR models, simultaneous SAR models, and panel dynamic spatial models. Recent econometric developments on intertemporal spatial models with rational expectations and flows data in trade theory will also be included. In terms of statistics, classical estimation, testing and inference are the main concerns, and we provide classical inference for the justification of Bayesian simulation approaches.
Download or read book Classical Swine Fever written by Fun-In Wang and published by MDPI. This book was released on 2021-01-19 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on the “disease aspects” of classical swine fever (CSF). The epidemiological pattern of the reemergence of CSF from wild boars and its spread to neighboring domestic pigs provides useful information for policy makers. The recent advances in diagnostics and vaccines and how each type of vaccine should be appropriately used in various field situations provide useful information for practicing veterinarians and laboratory scientists, for example, whether the vaccine virus attenuated enough to not cross the placenta to avoid sequelae, how innocuous samples like serum should be cautiously treated to avoid risk of virus spread, how various genotypes of the CSF virus evolve and compete to survive in the field, and how the CSF virus molecularly manipulates normal cell biological processes for its own advantage to survive. Phylogenetic analyses help in tracing the origin of the CSF virus responsible for each outbreak. Overall, readers should be impressed by the capabilities of CFS in pigs. We hope that this book can be a useful reference for all colleagues, whether in CSF-free or CSF-affected parts of the world.

Download or read book Modeling and Control of Engines and Drivelines written by Lars Eriksson and published by John Wiley & Sons. This book was released on 2014-04-07 with total page 589 pages. Available in PDF, EPUB and Kindle. Book excerpt: Control systems have come to play an important role in the performance of modern vehicles with regards to meeting goals on low emissions and low fuel consumption. To achieve these goals, modeling, simulation, and analysis have become standard tools for the development of control systems in the automotive industry. Modeling and Control of Engines and Drivelines provides an up-to-date treatment of the topic from a clear perspective of systems engineering and control systems, which are at the core of vehicle design. This book has three main goals. The first is to provide a thorough understanding of component models as building blocks. It has therefore been important to provide measurements from real processes, to explain the underlying physics, to describe the modeling considerations, and to validate the resulting models experimentally. Second, the authors show how the models are used in the current design of control and diagnosis systems. These system designs are never used in isolation, so the third goal is to provide a complete setting for system integration and evaluation, including complete vehicle models together with actual requirements and driving cycle analysis. Key features: Covers signals, systems, and control in modern vehicles Covers the basic dynamics of internal combustion engines and drivelines Provides a set of standard models and includes examples and case studies Covers turbo- and super-charging, and automotive dependability and diagnosis Accompanied by a web site hosting example models and problems and solutions Modeling and Control of Engines and Drivelines is a comprehensive reference for graduate students and the authors’ close collaboration with the automotive industry ensures that the knowledge and skills that practicing engineers need when analysing and developing new powertrain systems are also covered.

This book was released on 2021-06-25 with total page 664 pages. Available in PDF, EPUB and Kindle. Book excerpt: The COVID-19 pandemic drastically transformed the classroom by keeping students and teachers apart for the sake of safety. As schools emptied, remote learning rapidly expanded through online services and video chatrooms. Unfortunately, this disrupted many students and teachers who were not accustomed to remote classrooms. This challenge has forced K-12 teachers to think differently about teaching. Unexpectedly and with little time to prepare, they have been confronted with redesigning their curriculum and instruction from face-to-face to online virtual classrooms to protect students from the COVID-19 virus while ensuring that these new online initiatives remain sustainable and useful in the post-pandemic world. As teachers learn to take advantage of the affordances and strengths of the multiple technologies available for virtual classroom instruction, their instruction both in online and face-to-face will impact what and how students learn in the 21st century. The Handbook of Research on Transforming Teachers’ Online Pedagogical Reasoning for Engaging K-12 Students in Virtual Learning examines the best practices and pedagogical reasoning for designing online strategies that work for K-12 virtual learning. The initial section provides foundational pedagogical ideas for constructing engaging virtual learning environments that leverage the unique strengths and opportunities while avoiding the weaknesses and threats of the online world. The following chapters present instructional strategies for multiple grade levels and content areas: best practices that work, clearly describing why they work, and the teachers’ pedagogical reasoning that supports online implementations. The chapters provide ways to think about teaching in virtual environments that can be used to guide instructional strategy choices and recognizes the fundamental differences between face-to-face and virtual environments as an essential design component. Covering such topics as K-12 classrooms, pedagogical reasoning, and virtual learning, this text is perfect for professors, teachers, students, educational designers and developers, instructional technology faculty, distance learning faculty, and researchers interested in the subject.
