Statistical Rethinking


Book Description

Statistical Rethinking: A Bayesian Course with Examples in R and Stan builds readers’ knowledge of and confidence in statistical modeling. Reflecting the need for even minor programming in today’s model-based statistics, the book pushes readers to perform step-by-step calculations that are usually automated. This unique computational approach ensures that readers understand enough of the details to make reasonable choices and interpretations in their own modeling work. The text presents generalized linear multilevel models from a Bayesian perspective, relying on a simple logical interpretation of Bayesian probability and maximum entropy. It covers from the basics of regression to multilevel models. The author also discusses measurement error, missing data, and Gaussian process models for spatial and network autocorrelation. By using complete R code examples throughout, this book provides a practical foundation for performing statistical inference. Designed for both PhD students and seasoned professionals in the natural and social sciences, it prepares them for more advanced or specialized statistical modeling. Web Resource The book is accompanied by an R package (rethinking) that is available on the author’s website and GitHub. The two core functions (map and map2stan) of this package allow a variety of statistical models to be constructed from standard model formulas.




Advertising as Multilingual Communication


Book Description

Advertising has traditionally communicated messages to consumers with strong local and national identities. However, increasingly, products, producers, advertising agencies and media are becoming internationalized. In the development of strategies that appeal to a large multinational consumer base, advertising language takes on new 'multilingual' features. The author explores the role of advertising language in this new globalized environment, from a communicative theory point of view, as well as from a close linguistic analysis of some major advertising campaigns within a multicultural and multilingual marketplace.




Rethinking Property Tax Incentives for Business


Book Description

The use of property tax incentives for business by local governments throughout the United States has escalated over the last 50 years. While there is little evidence that these tax incentives are an effective instrument to promote economic development, they cost state and local governments $5 to $10 billion each year in forgone revenue. Three major obstacles can impede the success of property tax incentives as an economic development tool. First, incentives are unlikely to have a significant impact on a firm's profitability since property taxes are a small part of the total costs for most businesses--averaging much less than 1 percent of total costs for the U.S. manufacturing sector. Second, tax breaks are sometimes given to businesses that would have chosen the same location even without the incentives. When this happens, property tax incentives merely deplete the tax base without promoting economic development. Third, widespread use of incentives within a metropolitan area reduces their effectiveness, because when firms can obtain similar tax breaks in most jurisdictions, incentives are less likely to affect business location decisions. This report reviews five types of property tax incentives and examines their characteristics, costs, and effectiveness: property tax abatement programs; tax increment finance; enterprise zones; firm-specific property tax incentives; and property tax exemptions in connection with issuance of industrial development bonds. Alternatives to tax incentives should be considered by policy makers, such as customized job training, labor market intermediaries, and business support services. State and local governments also can pursue a policy of broad-based taxes with low tax rates or adopt split-rate property taxation with lower taxes on buildings than land.State policy makers are in a good position to increase the effectiveness of property tax incentives since they control how local governments use them. For example, states can restrict the use of incentives to certain geographic areas or certain types of facilities; publish information on the use of property tax incentives; conduct studies on their effectiveness; and reduce destructive local tax competition by not reimbursing local governments for revenue they forgo when they award property tax incentives.Local government officials can make wiser use of property tax incentives for business and avoid such incentives when their costs exceed their benefits. Localities should set clear criteria for the types of projects eligible for incentives; limit tax breaks to mobile facilities that export goods or services out of the region; involve tax administrators and other stakeholders in decisions to grant incentives; cooperate on economic development with other jurisdictions in the area; and be clear from the outset that not all businesses that ask for an incentive will receive one.Despite a generally poor record in promoting economic development, property tax incentives continue to be used. The goal is laudable: attracting new businesses to a jurisdiction can increase income or employment, expand the tax base, and revitalize distressed urban areas. In a best case scenario, attracting a large facility can increase worker productivity and draw related firms to the area, creating a positive feedback loop. This report offers recommendations to improve the odds of achieving these economic development goals.




Technology and Social Inclusion


Book Description

Much of the discussion about new technologies and social equality has focused on the oversimplified notion of a "digital divide." Technology and Social Inclusion moves beyond the limited view of haves and have-nots to analyze the different forms of access to information and communication technologies. Drawing on theory from political science, economics, sociology, psychology, communications, education, and linguistics, the book examines the ways in which differing access to technology contributes to social and economic stratification or inclusion. The book takes a global perspective, presenting case studies from developed and developing countries, including Brazil, China, Egypt, India, and the United States. A central premise is that, in today's society, the ability to access, adapt, and create knowledge using information and communication technologies is critical to social inclusion. This focus on social inclusion shifts the discussion of the "digital divide" from gaps to be overcome by providing equipment to social development challenges to be addressed through the effective integration of technology into communities, institutions, and societies. What is most important is not so much the physical availability of computers and the Internet but rather people's ability to make use of those technologies to engage in meaningful social practices.




Rethinking Class Size: The complex story of impact on teaching and learning


Book Description

The debate over whether class size matters for teaching and learning is one of the most enduring, and aggressive, in education research. Teachers often insist that small classes benefit their work. But many experts argue that evidence from research shows class size has little impact on pupil outcomes, so does not matter, and this dominant view has informed policymaking internationally. Here, the lead researchers on the world’s biggest study into class size effects present a counter-argument. Through detailed analysis of the complex relations involved in the classroom they reveal the mechanisms that support teachers’ experience, and conclude that class size matters very much indeed. Drawing on 20 years of systematic classroom observations, surveys of practitioners, detailed case studies and extensive reviews of research, Peter Blatchford and Anthony Russell contend that common ways of researching the impact of class size are limited and sometimes misguided. While class size may have no direct effect on pupil outcomes, it has, they say, significant force through interconnections with classroom processes. In describing these connections, the book opens up the everyday world of the classroom and shows that the influence of class size is everywhere. It impacts on teaching, grouping practices and classroom management, the quality of peer relations, tasks given to pupils, and on the time teachers have for marking, assessments and understanding the strengths and challenges for individual pupils. From their analysis, the authors develop a new social pedagogical model of how class size influences work, and identify policy conclusions and implications for teachers and schools.




Routledge Handbook of Japanese Sociolinguistics


Book Description

Presenting new approaches and results previously inaccessible in English, the Routledge Handbook of Japanese Sociolinguistics provides an insight into the language and society of contemporary Japan from a fresh perspective. While it was once believed that Japan was a linguistically homogenous country, research over the past two decades has shown Japan to be a multilingual and sociolinguistically diversifying country. Building on this approach, the contributors to this handbook take this further, combining Japanese and western approaches alike and producing research which is relevant to twenty-first century societies. Organised into five parts, the sections covered include: The languages and language varieties of Japan. The multilingual ecology. Variation, style and interaction. Language problems and language planning. Research overviews. With contributions from across the field of Japanese sociolinguistics, this handbook will prove very useful for students and scholars of Japanese Studies, as well as sociolinguists more generally.

Six authors an architect, four librarians, and a professor of art history and classics explore these questions this report. The authors challenge the reader to think about new potential for the place we call the library and underscore the growing importance of the library as a place for teaching, learning, and research in the digital age.




Codeswitching in the Classroom


Book Description

Bringing together sociolinguistic, linguistic, and educational perspectives, this cutting‐edge overview of codeswitching examines language mixing in teaching and learning in bilingual classrooms. As interest in pedagogical applications of bilingual language mixing increases, so too does a need for a thorough discussion of the topic. This volume serves that need by providing an original and wide-ranging discussion of theoretical, pedagogical, and policy‐related issues and obstacles in classroom settings—the pedagogical consequences of codeswitching for teaching and learning of language and content in one‐way and two‐way bilingual classrooms. Part I provides an introduction to (socio)linguistic and pedagogical contributions to scholarship in the field, both historical and contemporary. Part II focuses on codeswitching in teaching and learning, and addresses a range of pedagogical challenges to language mixing in a variety of contexts, such as literacy and mathematics instruction. Part III looks at language ideology and language policy to explore how students navigate educational spaces and negotiate their identities in the face of competing language ideologies and assumptions. This volume breaks new ground and serves as an important contribution on codeswitching for scholars, researchers, and teacher educators of language education, multilingualism, and applied linguistics.




Designing an Internet


Book Description

Why the Internet was designed to be the way it is, and how it could be different, now and in the future. How do you design an internet? The architecture of the current Internet is the product of basic design decisions made early in its history. What would an internet look like if it were designed, today, from the ground up? In this book, MIT computer scientist David Clark explains how the Internet is actually put together, what requirements it was designed to meet, and why different design decisions would create different internets. He does not take today's Internet as a given but tries to learn from it, and from alternative proposals for what an internet might be, in order to draw some general conclusions about network architecture. Clark discusses the history of the Internet, and how a range of potentially conflicting requirements—including longevity, security, availability, economic viability, management, and meeting the needs of society—shaped its character. He addresses both the technical aspects of the Internet and its broader social and economic contexts. He describes basic design approaches and explains, in terms accessible to nonspecialists, how networks are designed to carry out their functions. (An appendix offers a more technical discussion of network functions for readers who want the details.) He considers a range of alternative proposals for how to design an internet, examines in detail the key requirements a successful design must meet, and then imagines how to design a future internet from scratch. It's not that we should expect anyone to do this; but, perhaps, by conceiving a better future, we can push toward it.
