Once Can Be Enough


Book Description

There has recently been considerable discussion of a “replication crisis” in some areas of science. In this book, the authors argue that replication is not a necessary criterion for the validation of a scientific experiment. Five episodes from physics and genetics are used to substantiate this thesis: the Meselson-Stahl experiment on DNA replication, the discoveries of the positron and the omega minus hyperon, Mendel’s plant experiments, and the discovery of parity nonconservation. Two cases in which once wasn’t enough are also discussed, the nondiscovery of parity nonconservation and the search for magnetic monopoles. Reasons why once wasn’t enough are also discussed.




Reproducibility and Replicability in Science


Book Description

One of the pathways by which the scientific community confirms the validity of a new scientific discovery is by repeating the research that produced it. When a scientific effort fails to independently confirm the computations or results of a previous study, some fear that it may be a symptom of a lack of rigor in science, while others argue that such an observed inconsistency can be an important precursor to new discovery. Concerns about reproducibility and replicability have been expressed in both scientific and popular media. As these concerns came to light, Congress requested that the National Academies of Sciences, Engineering, and Medicine conduct a study to assess the extent of issues related to reproducibility and replicability and to offer recommendations for improving rigor and transparency in scientific research. Reproducibility and Replicability in Science defines reproducibility and replicability and examines the factors that may lead to non-reproducibility and non-replicability in research. Unlike the typical expectation of reproducibility between two computations, expectations about replicability are more nuanced, and in some cases a lack of replicability can aid the process of scientific discovery. This report provides recommendations to researchers, academic institutions, journals, and funders on steps they can take to improve reproducibility and replicability in science.




The First 20 Hours


Book Description

Forget the 10,000 hour rule— what if it’s possible to learn the basics of any new skill in 20 hours or less? Take a moment to consider how many things you want to learn to do. What’s on your list? What’s holding you back from getting started? Are you worried about the time and effort it takes to acquire new skills—time you don’t have and effort you can’t spare? Research suggests it takes 10,000 hours to develop a new skill. In this nonstop world when will you ever find that much time and energy? To make matters worse, the early hours of prac­ticing something new are always the most frustrating. That’s why it’s difficult to learn how to speak a new language, play an instrument, hit a golf ball, or shoot great photos. It’s so much easier to watch TV or surf the web . . . In The First 20 Hours, Josh Kaufman offers a systematic approach to rapid skill acquisition— how to learn any new skill as quickly as possible. His method shows you how to deconstruct com­plex skills, maximize productive practice, and remove common learning barriers. By complet­ing just 20 hours of focused, deliberate practice you’ll go from knowing absolutely nothing to performing noticeably well. Kaufman personally field-tested the meth­ods in this book. You’ll have a front row seat as he develops a personal yoga practice, writes his own web-based computer programs, teaches himself to touch type on a nonstandard key­board, explores the oldest and most complex board game in history, picks up the ukulele, and learns how to windsurf. Here are a few of the sim­ple techniques he teaches: Define your target performance level: Fig­ure out what your desired level of skill looks like, what you’re trying to achieve, and what you’ll be able to do when you’re done. The more specific, the better. Deconstruct the skill: Most of the things we think of as skills are actually bundles of smaller subskills. If you break down the subcompo­nents, it’s easier to figure out which ones are most important and practice those first. Eliminate barriers to practice: Removing common distractions and unnecessary effort makes it much easier to sit down and focus on deliberate practice. Create fast feedback loops: Getting accu­rate, real-time information about how well you’re performing during practice makes it much easier to improve. Whether you want to paint a portrait, launch a start-up, fly an airplane, or juggle flaming chain­saws, The First 20 Hours will help you pick up the basics of any skill in record time . . . and have more fun along the way.







Fostering Integrity in Research


Book Description

The integrity of knowledge that emerges from research is based on individual and collective adherence to core values of objectivity, honesty, openness, fairness, accountability, and stewardship. Integrity in science means that the organizations in which research is conducted encourage those involved to exemplify these values in every step of the research process. Understanding the dynamics that support â€" or distort â€" practices that uphold the integrity of research by all participants ensures that the research enterprise advances knowledge. The 1992 report Responsible Science: Ensuring the Integrity of the Research Process evaluated issues related to scientific responsibility and the conduct of research. It provided a valuable service in describing and analyzing a very complicated set of issues, and has served as a crucial basis for thinking about research integrity for more than two decades. However, as experience has accumulated with various forms of research misconduct, detrimental research practices, and other forms of misconduct, as subsequent empirical research has revealed more about the nature of scientific misconduct, and because technological and social changes have altered the environment in which science is conducted, it is clear that the framework established more than two decades ago needs to be updated. Responsible Science served as a valuable benchmark to set the context for this most recent analysis and to help guide the committee's thought process. Fostering Integrity in Research identifies best practices in research and recommends practical options for discouraging and addressing research misconduct and detrimental research practices.




The Childhood Conclusions Fix


Book Description

Reading this book, you get the sense that Lisette Schuitemaker sees right through you. As if she knows that you gorge on chocolate at times, that you go crazy if people know something you don’t, that you are bound to hit the slow cashier one day. Or that in truth you’re not here at all with your thoughts. And how ardently you hope that one day someone will truly love you the way you are. You, me, all of us have drawn some conclusions in our childhood: impressions we got as a young child and the conclusions we jumped to about ourselves, the world and our place in it. These childhood conclusions still produce habitual thoughts that mark our behaviors. “Why didn’t I know this before and why don’t we all know this?’ were the questions that prompted the author to share her insights. Illustrated with examples from her private practice she shows how childhood conclusions are at work in all of us--and how we can turn them around into a positive outlook on ourselves and others. The five childhood conclusions tell you exactly what you think about yourself. And how you could think differently. And gain so much more freedom for living your life. This book is for anyone who is curious where their habitual thoughts arise from.

Marry Him


Book Description

An eye-opening, funny, painful, and always truthful in-depth examination of modern relationships, and a wake-up call for single women about getting real about Mr. Right, from the New York Times bestselling author of Maybe You Should Talk to Someone. You have a fulfilling job, great friends, and the perfect apartment. So what if you haven’t found “The One” just yet. He’ll come along someday, right? But what if he doesn’t? Or what if Mr. Right had been, well, Mr. Right in Front of You—but you passed him by? Nearing forty and still single, journalist Lori Gottlieb started to wonder: What makes for lasting romantic fulfillment, and are we looking for those qualities when we’re dating? Are we too picky about trivial things that don’t matter, and not picky enough about the often overlooked things that do? In Marry Him, Gottlieb explores an all-too-common dilemma—how to reconcile the desire for a happy marriage with a list of must-haves and deal-breakers so long and complicated that many great guys get misguidedly eliminated. On a quest to find the answer, Gottlieb sets out on her own journey in search of love, discovering wisdom and surprising insights from sociologists and neurobiologists, marital researchers and behavioral economists—as well as single and married men and women of all generations.




Fracking 101


Book Description

Fracking, or hydraulic fracturing to give its proper name, has become part of our lives recently, due to the massive exploitation of America’s shale oil and gas fields. Along the way it has stirred up controversy, with passionate opponents fighting against the oil companies. The fight has generated a lot of heat, but not much understanding. This guide, written by some-one who knows what he is talking about takes a detached, neutral view of the subject. Without pushing a view for or against, it provides the factual background you need to form an opinion of your own. An Informed and Neutral Introduction Like most people I have heard of fracking, but did I really understand what it was? To answer honestly, no. I knew it had something to do with mining and was perhaps destructive to the land. To me, it was just one of those words of the moment. This guide has given me a real sense and understanding of what fracking is. It allowed me, someone who has no experience in this field, to learn about the pros and cons of fracking, without having the good and bad of it forced down my throat. If you want an informed and neutral introduction into fracking, then this is the guide for you. ~ Debbie Prewer
