Research Brief March 2017 Publication #2017-16
Research Brief March 2017 Publication #2017-16 Flourishing From the Start: What Is It and How Can It Be Measured? Kristin Anderson Moore, PhD, Child Trends Christina D. Bethell, PhD, The Child and Adolescent Health Measurement Introduction Initiative, Johns Hopkins Bloomberg School of Every parent wants their child to flourish, and every community wants its Public Health children to thrive. It is not sufficient for children to avoid negative outcomes. Rather, from their earliest years, we should foster positive outcomes for David Murphey, PhD, children. Substantial evidence indicates that early investments to foster positive child development can reap large and lasting gains.1 But in order to Child Trends implement and sustain policies and programs that help children flourish, we need to accurately define, measure, and then monitor, “flourishing.”a Miranda Carver Martin, BA, Child Trends By comparing the available child development research literature with the data currently being collected by health researchers and other practitioners, Martha Beltz, BA, we have identified important gaps in our definition of flourishing.2 In formerly of Child Trends particular, the field lacks a set of brief, robust, and culturally sensitive measures of “thriving” constructs critical for young children.3 This is also true for measures of the promotive and protective factors that contribute to thriving. Even when measures do exist, there are serious concerns regarding their validity and utility. We instead recommend these high-priority measures of flourishing -
Markdown: Syntax
Markdown Syntax | Fall 2021-22 Markdown: Syntax ● Overview ❍ Philosophy ❍ Inline HTML ❍ Automatic Escaping for Special Characters ● Block Elements ❍ Paragraphs and Line Breaks ❍ Headers ❍ Blockquotes ❍ Lists ❍ Code Blocks ❍ Horizontal Rules ● Span Elements ❍ Links ❍ Emphasis ❍ Code ❍ Images ● Miscellaneous ❍ Backslash Escapes ❍ Automatic Links Overview Philosophy Markdown is intended to be as easy-to-read and easy-to-write as is feasible. Readability, however, is emphasized above all else. A Markdown-formatted document should be publishable as-is, as plain text, without looking like it's been marked up with tags or formatting instructions. While Markdown's syntax has been influenced by several existing text-to-HTML filters -- including Setext, atx, Textile, reStructuredText, Grutatext, and EtText -- the single biggest source of inspiration for Markdown's syntax is the format of plain text email. To this end, Markdown's syntax is comprised entirely of punctuation characters, which punctuation characters have been carefully chosen so as to look like what they mean. E.g., asterisks around a word actually look like *emphasis*. Markdown lists look like, well, lists. Even blockquotes look like quoted passages of text, assuming you've ever used email. Inline HTML Markdown's syntax is intended for one purpose: to be used as a format for writing for the web. Markdown is not a replacement for HTML, or even close to it. Its syntax is very small, corresponding only to a very small subset of HTML tags. The idea is not to create a syntax that makes it easier to insert HTML tags. In my opinion, HTML tags are already easy to insert. -

Why Scholars Should Write in Markdown
A Why scholars should write in Markdown Stuart M. Shieber With few exceptions, scholars would be better off writing their papers in a lightweight markup format called Markdown, rather than using a word-processing program like Microsoft Word. This post explains why, and reveals a hidden agenda as well.1 MICROSOFT WORD IS NOT APPROPRIATE FOR SCHOLARLY ARTICLE PRODUCTION Before turning to lightweight markup, I review the problems with Microsoft Word as the lingua franca for producing scholarly articles. This ground has been heavily covered. (Here’s a recent example.) The problems include: Substantial learning curve. Microsoft Word is a complicated program that is difficult to use well. Appearance versus structure. Word-processing programs like Word conflate composition with typesetting. They work by having you specify how a document should look, not how it is structured. A classic example is section headings. In a typical markup language, you specify that something is a heading by marking it as a heading. In a word-processing program you might specify that something is a heading by increasing the font size and making it bold. Yes, Word has “paragraph styles”, and some people sometimes use them more or less properly, if you can figure out how. But most people don’t, or don’t do so consistently, and the resultant chaos has been well documented. It has led to a whole industry of people who specialize in massaging Word files into some semblance of consistency. Backwards compatibility. Word-processing program file formats have a tendency to change. Word itself has gone through multiple incompatible file formats in the last decades, one every couple of years. -
Instructions for Creating Your Own R Package∗
Instructions for Creating Your Own R Package∗ In Song Kimy Phil Martinz Nina McMurryx Andy Halterman{ March 18, 2018 1 Introduction The following is a step-by-step guide to creating your own R package. Even beyond this course, you may find this useful for storing functions you create for your own research or for editing existing R packages to suit your needs. This guide contains three different sets of instructions. If you use RStudio, you can follow the \Ba- sic Instructions" in Section 2 which involve using RStudio's interface. If you do not use RStudio or you do use RStudio but want a little bit more of control, follow the instructions in Section 3. Section 4 illustrates how to create a R package with functions written in C++ via Rcpp helper functions. NOTE: Write all of your functions first (in R or RStudio) and make sure they work properly before you start compiling your package. You may also want to try compiling with a very simple function first (e.g. myfun <- function(x)fx + 7g). 2 Basic Instructions (for RStudio Users Only) All of the following should be done in RStudio, unless otherwise noted. Even if you build your package in RStudio using the \Basic Instructions," we strongly recommend that you carefully review the \Advanced Instructions" as well. RStudio has built-in tools that will do many of these steps for you, but knowing how to do them manually will make it easier for you to build and distribute your own packages in the future and/or adapt existing packages. -

A Practical Guide for Improving Transparency and Reproducibility in Neuroimaging Research Krzysztof J
bioRxiv preprint first posted online Feb. 12, 2016; doi: http://dx.doi.org/10.1101/039354. The copyright holder for this preprint (which was not peer-reviewed) is the author/funder. It is made available under a CC-BY 4.0 International license. A practical guide for improving transparency and reproducibility in neuroimaging research Krzysztof J. Gorgolewski and Russell A. Poldrack Department of Psychology, Stanford University Abstract Recent years have seen an increase in alarming signals regarding the lack of replicability in neuroscience, psychology, and other related fields. To avoid a widespread crisis in neuroimaging research and consequent loss of credibility in the public eye, we need to improve how we do science. This article aims to be a practical guide for researchers at any stage of their careers that will help them make their research more reproducible and transparent while minimizing the additional effort that this might require. The guide covers three major topics in open science (data, code, and publications) and offers practical advice as well as highlighting advantages of adopting more open research practices that go beyond improved transparency and reproducibility. Introduction The question of how the brain creates the mind has captivated humankind for thousands of years. With recent advances in human in vivo brain imaging, we how have effective tools to peek into biological underpinnings of mind and behavior. Even though we are no longer constrained just to philosophical thought experiments and behavioral observations (which undoubtedly are extremely useful), the question at hand has not gotten any easier. These powerful new tools have largely demonstrated just how complex the biological bases of behavior actually are. -
Percent R, X and Z Based on Transformer KVA
SHORT CIRCUIT FAULT CALCULATIONS Short circuit fault calculations as required to be performed on all electrical service entrances by National Electrical Code 110-9, 110-10. These calculations are made to assure that the service equipment will clear a fault in case of short circuit. To perform the fault calculations the following information must be obtained: 1. Available Power Company Short circuit KVA at transformer primary : Contact Power Company, may also be given in terms of R + jX. 2. Length of service drop from transformer to building, Type and size of conductor, ie., 250 MCM, aluminum. 3. Impedance of transformer, KVA size. A. %R = Percent Resistance B. %X = Percent Reactance C. %Z = Percent Impedance D. KVA = Kilovoltamp size of transformer. ( Obtain for each transformer if in Bank of 2 or 3) 4. If service entrance consists of several different sizes of conductors, each must be adjusted by (Ohms for 1 conductor) (Number of conductors) This must be done for R and X Three Phase Systems Wye Systems: 120/208V 3∅, 4 wire 277/480V 3∅ 4 wire Delta Systems: 120/240V 3∅, 4 wire 240V 3∅, 3 wire 480 V 3∅, 3 wire Single Phase Systems: Voltage 120/240V 1∅, 3 wire. Separate line to line and line to neutral calculations must be done for single phase systems. Voltage in equations (KV) is the secondary transformer voltage, line to line. Base KVA is 10,000 in all examples. Only those components actually in the system have to be included, each component must have an X and an R value. Neutral size is assumed to be the same size as the phase conductors. -

The Constraint on Public Debt When R<G but G<M
The constraint on public debt when r < g but g < m Ricardo Reis LSE March 2021 Abstract With real interest rates below the growth rate of the economy, but the marginal prod- uct of capital above it, the public debt can be lower than the present value of primary surpluses because of a bubble premia on the debt. The government can run a deficit forever. In a model that endogenizes the bubble premium as arising from the safety and liquidity of public debt, more government spending requires a larger bubble pre- mium, but because people want to hold less debt, there is an upper limit on spending. Inflation reduces the fiscal space, financial repression increases it, and redistribution of wealth or income taxation have an unconventional effect on fiscal capacity through the bubble premium.
