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 -
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.

Manner of Articulation
An Animated and Narrated Glossary of Terms used in Linguistics presents Manner of Articulation Articulators Slide 2 Page 1 Manner of Articulation • The manner of articulation refers to the way airflow is controlled in the production of a phone (i.e. a linguistic sound). Slide 3 Manner of Articulation on the IPA Chart Plosive Nasal Trill Tap or Flap Fricative Lateral fricative Approximant Lateral approximant Manner of articulation Slide 4 Page 2 Plosive p Plosives require total obstruction of airflow. Slide 5 Nasal n Nasals require air to flow out of the nose. Slide 6 Page 3 Trill r Trills are made by rapid succession of contact between articulators that obstruct airflow. Slide 7 Tap or Flap A tap or flap is like trill, except that there is only one rapid contact between the articulators. There is some difference between tap and flap, but we shall not pursue that here. Slide 8 Page 4 Fricative f A fricative is formed when the stricture is very narrow (but without total closure) so that when air flows out, a hissing noise is made. Slide 9 Approximant An approximant is a phone made when the obstruction of airflow does not produce any audible friction. Slide 10 Page 5 Lateral l A lateral is made when air flows out of the sides of the mouth. Slide 11 Note • In this presentation, we have concentrated on the pulmonic consonants, but manners of articulation may be used to describe vowels and other linguistic sounds as well.

Reading Source Data in R
Reading Source Data in R R is useful for analyzing data, once there is data to be analyzed. Real datasets come from numerous places in various formats, many of which actually can be leveraged by the savvy R programmer with the right set of packages and practices. *** Note: It is possible to stream data in R, but it’s probably outside of the scope of most educational uses. We will only be worried about static data. *** Understanding the flow of data How many times have you accessed some information in a browser or software package and wished you had that data as a spreadsheet or csv instead? R, like most programming languages, can serve as the bridge between the information you have and the information you want. A significant amount of programming is an exercise in changing file formats. Source Result Data R Data To use R for data manipulation and analysis, source data must be read in, analyzed or manipulated as necessary, and the results are output in some meaningful format. This document focuses on the red arrow: How is source data read into R? The ability to access data is fundamental to building useful, productive systems, and is sometimes the biggest challenge Immediately preceding the scope of this document is the source data itself. It is left to the reader to understand the source data: How and where it is stored, in what file formats, file ownership and permissions, etc. Immediately beyond the scope of this document is actual programming. It is left to the reader to determine which tools and methods are best applied to the source data to yield the desired results. -

The Diachronic Emergence of Retroflex Segments in Three Languages* 1
View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Hochschulschriftenserver - Universität Frankfurt am Main The diachronic emergence of retroflex segments in three languages* Silke Hamann ZAS (Centre for General Linguistics), Berlin [email protected] The present study shows that though retroflex segments can be considered articulatorily marked, there are perceptual reasons why languages introduce this class into their phoneme inventory. This observation is illustrated with the diachronic developments of retroflexes in Norwegian (North- Germanic), Nyawaygi (Australian) and Minto-Nenana (Athapaskan). The developments in these three languages are modelled in a perceptually oriented phonological theory, since traditional articulatorily-based features cannot deal with such processes. 1 Introduction Cross-linguistically, retroflexes occur relatively infrequently. From the 317 languages of the UPSI database (Maddieson 1984, 1986), only 8.5 % have a voiceless retroflex stop [ˇ], 7.3 % a voiced stop [Í], 5.3 % a voiceless retroflex fricative [ß], 0.9 % a voiced fricative [¸], and 5.9 % a retroflex nasal [˜]. Compared to other segmental classes that are considered infrequent, such as a palatal nasal [¯], which occurs in 33.7 % of the UPSID languages, and the uvular stop [q], which occurs in 14.8 % of the languages, the percentages for retroflexes are strikingly low. Furthermore, typically only large segment inventories have a retroflex class, i.e. at least another coronal segment (apical or laminal) is present, as in Sanskrit, Hindi, Norwegian, Swedish, and numerous Australian Aboriginal languages. Maddieson’s (1984) database includes only one exception to this general tendency, namely the Dravidian language Kota, which has a retroflex as its only coronal fricative. -
Metathesis in Judeo-Spanish Consonant Clusters
Metathesis in Judeo-Spanish Consonant Clusters Travis G. Bradley UC Davis 1. Introduction Judeo-Spanish (JS) denotes those varieties of Spanish preserved by the Sephardic Jews who were expelled from Spain in 1492 and have emigrated throughout Europe, North Africa, the Middle East, and the United States. Some descriptions of JS emphasize its conservative, archaic nature, highlighting its similarities to Old Spanish (OS), while other research points up the novel characteristics that distinguish JS from both OS and other varieties of Modern Spanish (MS). Despite its status as an endangered language due to the lack of monolingual speakers and to the ever decreasing number of fluent speakers under the age of fifty-five (T. Harris 1994), modern JS remains underrepresented in the most recent work on Ibero-Romance phonetics and phonology (although see Bradley and Delforge 2006 on sibilant voicing and rhotics in Istanbul JS). One phonological phenomenon of JS in which both retention and innovation can be observed is consonant metathesis. This paper examines two types of productive metathesis in JS consonant clusters, e.g., daldo < dadlo ‘give (PL.) it’ and tadre < tarde ‘late, afternoon’. Holt (2004) proposes an account in Optimality Theory of dl and dn metathesis in OS as a strategy for repairing bad syllable contact. I show how the analysis straightforwardly accounts for dl metathesis in JS imperative-clitic sequences. In OS, metathesis did not affect heteromorphemic dm clusters, and the same restriction is found in modern-day JS, e.g., dadme vs. *damde/dande ‘give (PL.) me’. I extend Holt’s account, through nasal place assimilation and positional faithfulness constraints, in order to explain the failure of dm metathesis across morpheme boundaries. -
A Case Study of Norwegian Clusters

Morphological derived-environment effects in gestural coordination: a case study of Norwegian clusters Travis G. Bradley* Department of Spanish and Classics, University of California, 705 Sproul Hall, One Shields Avenue, Davis, CA 95616, USA Abstract This paper examines morphophonological alternations involving apicoalveolar tap- consonant clusters in Urban East Norwegian from the framework of gestural Optimality Theory. Articulatory Phonology provides an insightful explanation of patterns of vowel intrusion, coalescence, and rhotic deletion in terms of the temporal coordination of consonantal gestures, which interacts with both prosodic and morphological structure. An alignment-based account of derived-environment effects is proposed in which complete overlap in rhotic-consonant clusters is blocked within morphemes but not across morpheme or word boundaries. Alignment constraints on gestural coordination also play a role in phonologically conditioned allomorphy. The gestural analysis is contrasted with alternative Optimality-theoretic accounts. Furthermore, it is argued that models of the phonetics-phonology interface which view timing as a low-level detail of phonetic implementation incorrectly predict that input morphological structure should have no effect on gestural coordination. The patterning of rhotic-consonant clusters in Norwegian is consistent with a model that includes gestural representations and constraints directly in the phonological grammar, where underlying morphological structure is still visible. -
