Download or read book Does Television Rot Your Brain New Evidence from the Coleman Study written by Matthew Gentzkow and published by . This book was released on 2020 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: We use heterogeneity in the timing of television's introduction to different local markets to identify the effect of preschool television exposure on standardized test scores later in life. Our preferred point estimate indicates that an additional year of preschool television exposure raises average test scores by about .02 standard deviations. We are able to reject negative effects larger than about .03 standard deviations per year of television exposure. For reading and general knowledge scores, the positive effects we find are marginally statistically significant, and these effects are largest for children from households where English is not the primary language, for children whose mothers have less than a high school education, and for non-white children. To capture more general effects on human capital, we also study the effect of childhood television exposure on school completion and subsequent labor market earnings, and again find no evidence of a negative effect.

Available in PDF, EPUB and Kindle. Book excerpt: The mind behind the infamous Ig Nobel Prizes presents an addictive collection of improbable research all about us – and you Marc Abrahams collects the odd, the imaginative and the brilliantly improbable. Here he turns to research on the ins and outs of the very improbable evolutionary innovation that is the human body (brain included): • What’s the best way to get a monkey to floss regularly? • How much dandruff do Pakistani soldiers have? • If you add an extra henchman to your bank-robbing gang, how much more money will you 'earn'? • How many dimples will be found on the cheeks of 28,282 Greek children? • Who is the Einstein of pork carcasses?
Download or read book How Toddlers Learn the Secret Language of Movies written by Cary Bazalgette and published by Springer Nature. This book was released on 2022-05-18 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book takes a radically new approach to the well-worn topic of children's relationship with the media, avoiding the "risks and benefits" paradigm while examining very young children's interactions with film and television. Bazalgette proposes a refocus on the learning processes that children must go through in order to understand what they are watching on televisions, phones, or iPads. To demonstrate this, she offers unique insight from research done with her twin grandchildren starting from just before they were two years old, with analysis drawn from the field of embodied cognition to help identify minute behaviours and expressions as signals of emotions and thought processes. The book makes the case that all inquiry into early childhood movie-viewing should be based on the premise that learning–usually self-driven–is taking place throughout.
Download or read book Steady Gains and Stalled Progress written by Katherine Magnuson and published by Russell Sage Foundation. This book was released on 2008-10-09 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: Addressing the disparity in test scores between black and white children remains one of the greatest social challenges of our time. Between the 1960s and 1980s, tremendous strides were made in closing the achievement gap, but that remarkable progress halted abruptly in the mid 1980s, and stagnated throughout the 1990s. How can we understand these shifting trends and their relation to escalating economic inequality? In Steady Gains and Stalled Progress, interdisciplinary experts present a groundbreaking analysis of the multifaceted reasons behind the test score gap—and the policies that hold the greatest promise for renewed progress in the future. Steady Gains and Stalled Progress shows that while income inequality does not directly lead to racial differences in test scores, it creates and exacerbates disparities in schools, families, and communities—which do affect test scores. Jens Ludwig and Jacob Vigdor demonstrate that the period of greatest progress in closing the gap coincided with the historic push for school desegregation in the 1960s and 1970s. Stagnation came after efforts to integrate schools slowed down. Today, the test score gap is nearly 50 percent larger in states with the highest levels of school segregation. Katherine Magnuson, Dan Rosenbaum, and Jane Waldfogel show how parents' level of education affects children's academic performance: as educational attainment for black parents increased in the 1970s and 1980s, the gap in children's test scores narrowed. Sean Corcoran and William Evans present evidence that teachers of black students have less experience and are less satisfied in their careers than teachers of white students. David Grissmer and Elizabeth Eiseman find that the effects of economic deprivation on cognitive and emotional development in early childhood lead to a racial divide in school readiness on the very first day of kindergarten. Looking ahead, Helen Ladd stresses that the task of narrowing the divide is not one that can or should be left to schools alone. Progress will resume only when policymakers address the larger social and economic forces behind the problem. Ronald Ferguson masterfully interweaves the volume's chief findings to highlight the fact that the achievement gap is the cumulative effect of many different processes operating in different contexts. The gap in black and white test scores is one of the most salient features of racial inequality today. Steady Gains and Stalled Progress provides the detailed information and powerful insight we need to understand a complicated past and design a better future.

Download or read book Sense Making and Shared Meaning in Language and Literacy Education written by Sharon Murphy and published by Routledge. This book was released on 2020-07-15 with total page 238 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook provides a framework for teaching children’s language and literacy and introduces research-based tactics for teachers to use in designing their literacy programs for children. Exploring how sense-making occurs in contemporary literacy practice, Murphy comprehensively covers major topics in literacy, including contemporary multimodal literacy practices, classroom discourse, literacy assessment, language and culture, and teacher knowledge. Organized around themes—talk, reading and composing representation—this book comprehensively invites educators to make sense of their own teaching practices while demonstrating the complexities of how children make sense of and represent meaning in today’s world. Grounded in research, this text features a wealth of real-world, multimodal examples, effective strategies and teaching tactics to apply to any classroom context. Ideal for literacy courses, preservice teachers, teacher educators and literacy scholars, this book illustrates how children become literate in contemporary society and how teachers can create the conditions for children to broaden and deepen their sense-making and expressive efforts.
Download or read book Raising Happy Healthy Children written by Sally Goddard Blythe and published by Hawthorn Press. This book was released on 2020-05-10 with total page 439 pages. Available in PDF, EPUB and Kindle. Book excerpt: With new information carefully added, this book examines the crucial early years from a child's perspective. It draws on the latest scientific research to show how the first few years determine the way children develop, body and mind, for the rest of their lives. The keys to this development are parents, and in particular mothers. Raising Happy Healthy Children presents convincing research to show how a baby's relationship with its mother has a lasting, deep impact. Recent social changes, such as delayed motherhood, juggling of work/life balance, limited uptake of breastfeeding, and use of parent-substitute baby equipment and electronic devices, are interfering with key developmental milestones that are essential for wellbeing in later life.

Available in PDF, EPUB and Kindle. Book excerpt: Interest in prediction markets has increased in the last decade, driven in part by the hope that these markets will prove to be valuable tools in forecasting, decision-making and risk management -- in both the public and private sectors. This paper outlines five open questions in the literature, and we argue that resolving these questions is crucial to determining whether current optimism about prediction markets will be realized.
Download or read book The Effects of Entry on Incumbent Innovation and Productivity written by Philippe Aghion and published by . This book was released on 2006 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: How does firm entry affect innovation incentives and productivity growth in incumbent firms? Micro-data suggests that there is heterogeneity across industries--incumbents in technologically advanced industries react positively to foreign firm entry, but not in laggard industries. To explain this pattern, we introduce entry into a Schumpeterian growth model with multiple sectors which differ by their distance to the technological frontier. We show that technologically advanced entry threat spurs innovation incentives in sectors close to the technological frontier--successful innovation allows incumbents to prevent entry. In laggard sectors it discourages innovation--increased entry threat reduces incumbents' expected rents from innovating. We find that the empirical patterns hold using rich micro-level productivity growth and patent panel data for the UK, and controlling for the endogeneity of entry by exploiting the large number of policy reforms undertaken during the Thatcher era.

Book excerpt: We study the effects of the progressive elimination of the system of industrial regulations on entry and production, known as the "license raj," on registered manufacturing output, employment, entry and investment across Indian states with different labor market regulations. The effects are found to be unequal depending on the institutional environment in which industries are embedded. In particular, following delicensing, industries located in states with pro-employer labor market institutions grew more quickly than those in pro-worker environments.
Download or read book Soap Operas and Fertility written by Eliana La Ferrara and published by . This book was released on 2008 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: What are the effects of television, and of role models portrayed in TV programs, on individual behavior? We focus on fertility choices in Brazil, a country where soap operas (novelas) portray families that are much smaller than in reality. We exploit differences in the timing of entry into different markets of Rede Globo, the network that has an effective monopoly on novelas production in this country. Using Census data for the period 1970-1991, we find that women living in areas covered by the Globo signal have significantly lower fertility. The effect is strongest for women of lower socioeconomic status and for women in the central and late phases of their fertility cycle, consistent with stopping behavior. The result is robust to placebo treatments and does not appear to be driven by selection in Globo entry. Finally, we provide suggestive evidence that novelas, and not just television, affected individual choices. First, people living in areas covered by the signal were more likely to name their children after novela characters. Second, entry of a network that relied on imported shows did not have a significant impact on fertility
Download or read book Pervasive Stickiness expanded Version written by N. Gregory Mankiw and published by . This book was released on 2006 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper explores a macroeconomic model of the business cycle in which stickiness of information is pervasive. We start from a familiar benchmark classical model and add to it the assumption that there is sticky information on the part of consumers, workers, and firms. We evaluate the model against three key facts that describe short-run fluctuations: the acceleration phenomenon, the smoothness of real wages, and the gradual response of real variables to shocks. We find that pervasive stickiness is required to fit the facts. We conclude that models based on stickiness of information offer the promise of fitting the facts on business cycles while adding only one new plausible ingredient to the classical benchmark.
