The Effects of Early Intervention on the Expressive Language Outcomes of Children with Autism Spectrum Disorder: A Systematic Review

Background: Autism Spectrum Disorder (ASD) is characterized by persistent challenges in social communication as well as restricted and repetitive behaviors and is often observable in early childhood. Expressive language delays are common in young children diagnosed with ASD. Expressive language includes any form of communicative output, such as verbal language, sign language, and the use of alternative and augmentative communication (AAC). Early intervention, for the purpose of this systematic review, is defined as speech and language services provided before a child is 5 years (60 months) of age. Evidence suggests that early intervention can lead to positive outcomes in the symptoms of children with ASD. Objective: To determine whether early intervention of ASD in children between 0-59 months of age has positive effects on expressive language development. Methods: A systematic search of the PsychINFO, PubMED, CINAHL, ERIC, and LLBA database was conducted, followed by a qualitative analysis of relevant articles. Studies included monolingual (i.e., English) children who were diagnosed with ASD. Studies were systematically graded and processed using inter-rater procedures. Results: Fourteen articles were included based upon inclusionary criteria. The overall quality of the studies was moderate. The most widely used early intervention techniques included the Early Start Denver Model (ESDM) and Pivotal Response Training (PRT). Conclusions: Consistent high-interval (i.e., 25 hours per week), behaviorally-based early intervention (i.e., before 40 months) may lead to positive outcomes in expressive language development. Clinicians working with young children with ASD should implement behaviorally-based, empirically-supported interventions, such as ESDM or PRT. Future research should prioritize high-quality study designs (e.g., randomized control trials) with larger sample sizes of children diagnosed with ASD, which is necessary to discern a direct relationship between behaviorally-based early intervention and expressive language outcomes for children with ASD.https://scholarworks.uvm.edu/csdms/1008/thumbnail.jp

Interview of Margaret Peggy Emme

Margaret “Peggy” Walsh Emme was born in Philadelphia, PA in 1957 at Nazareth Hospital. Her parents are Marita A. Dunphy and Richard J. Walsh. They both owned business while Mrs. Emme was a child. Her mother owned a small boutique in the basement of her parents’ house (Mrs. Emme’s maternal grandparents) and her father owned a local tavern. Mrs. Emme would help out at both of these businesses. Mrs. Emme is the oldest of five children. Her four younger brothers are: Richard, Michael, Brian, and John. She attended Catholic school as a child, first attending St. Bernard’s Parochial School and then St. Hubert’s Catholic High School for Girls. Mrs. Emme graduated from St. Hubert’s in 1975. She was married twice. She married her first husband, Mr. Eddie Laurer in 1975. Mrs. Emme remains married to her second husband, James L. Emme, whom she married in 1984. She has mothered two children: a daughter, Jamie Emme, and a son, James “Foz” Emme. Both of her children graduated from LaSalle University. Mrs. Emme herself graduated from LaSalle in 2008 and 2011, respectively. She received an AA Liberal Arts in 2008 and a BS Business Administration in 2011. Throughout her life, Mrs. Emme has spent time working in both the corporate world and the academic one. She worked at Film Corporation of America, General Accident Life Assurance Corporation of America, Inter Space Interior Design, and Spiegel. She has also served as a lunch mother at St. Matthew’s Parochial School and has held various positions at LaSalle University. For example, Mrs. Emme worked under three separate university presidents as their back up secretary. The presidents were: Br. Joseph Burke, FSC; Mr. Nicholas Giordano, and Br. Michael McGinnis, FSC. Mrs. Emme claims to have a close relationship with several of the Christian Brothers. She also worked under two Vice Presidents of Enrollment Services: Mr. Ray Ritchie and Mr. John Dolan. Currently, Mrs. Emme is the Assistant Director of Transfer Admissions at LaSalle University. Mrs. Emme had not been interviewed previously and she offers valuable insights since she experienced LaSalle as a student, employee, and mother of alumni. Furthermore, she has interesting takes on the differences between corporate and academia and she speaks freely of her experiences here at LaSalle University

Just-Right Government: Interstate Compacts and Multistate Governance in an Era of Political Polarization, Policy Paralysis, and Bad-Faith Partisanship

Those committed to addressing the political, economic, and moral crises of the day— voting rights, racial justice, reproductive autonomy, gaping inequality, LGBTQ rights, and public health and safety—don’t know where to turn. Federal legislative and regulatory pathways are choked off by senators quick to filibuster and by judges eager to strike down agency rules and orders. State pathways, in turn, are compromised by limited capacity, collective action problems, externalities, scant economies of scale, and—in many jurisdictions—a toxic political culture hostile to even the most anodyne government interventions. Recognizing the limited options available on a binary (that is, federal or state) governance roadmap, this Article prescribes charting a third pathway: interstate agreements and compacts. Such arrangements—largely unnecessary when Washington is not pathologically dysfunctional—have a long and venerable constitutional pedigree and provide a legally sound and politically expedient “just-right” solution. Grouping clusters of states along the Pacific Ocean, the Amtrak Corridor, and the Upper Midwest, we propose and briefly sketch four major compacts as cornerstones of a Blue New Deal. Beyond detailing the four strategic interventions designed principally to work around the instant federal and state roadblocks (and recognizing similar opportunities for purple and, possibly, red states, too), this Article makes the affirmative, normative case for interstate agreements and compacts playing a long term, regular, and prominent role in twenty-first-century American governance—a case that sounds in democratic theory, administrative law, and political economy

Determination of the top quark mass from the t¯t cross section measured by CMS at √s = 7TeV

Higher-order QCD predictions are used to extract the top quark mass, both in the pole and in the MS scheme, from the top quark pair production cross section measured in the dilepton final state. The analyzed dataset corresponds to an integrated luminosity of 1.14 fb−1 collected by the CMS experiment in 2011 in pp collisions at √s = 7TeV

Recent Personnel Research Significant to Vital Educational Procedures

The attitude of college faculties toward counseling or personnel work varies from positive rejection and ridicule to enthusiastic endorsement and unquestioned acceptance. A few typical faculty reactions indicate positive or negative reaction to personnel procedure

Signed, Introspective Methodologies

Real-time modalities and interrupts have garnered profound interest from both biologists and developers in the last several years. Given the current status of permutable theory, systems engineers dubiously desire the construction of model checking. We argue that although the little-known metamorphic algorithm for the theoretical unification of compilers and the location-identity split by Richard Hubbard [1] runs in Ω(logn + n + logloglog(loglogn + loglogloglogn)) time,nRPCs can be made semantic, homogeneous, and trainable

Search for the standard model Higgs boson in the H to ZZ to 2l 2nu channel in pp collisions at sqrt(s) = 7 TeV

A search for the standard model Higgs boson in the H to ZZ to 2l 2nu decay channel, where l = e or mu, in pp collisions at a center-of-mass energy of 7 TeV is presented. The data were collected at the LHC, with the CMS detector, and correspond to an integrated luminosity of 4.6 inverse femtobarns. No significant excess is observed above the background expectation, and upper limits are set on the Higgs boson production cross section. The presence of the standard model Higgs boson with a mass in the 270-440 GeV range is excluded at 95% confidence level.Comment: Submitted to JHE

Measurements of branching fraction ratios and CP-asymmetries in suppressed B^- -> D(-> K^+ pi^-)K^- and B^- -> D(-> K^+ pi^-)pi^- decays

We report the first reconstruction in hadron collisions of the suppressed decays B^- -> D(-> K^+ pi^-)K^- and B^- -> D(-> K^+ pi^-)pi^-, sensitive to the CKM phase gamma, using data from 7 fb^-1 of integrated luminosity collected by the CDF II detector at the Tevatron collider. We reconstruct a signal for the B^- -> D(-> K^+ pi^-)K^- suppressed mode with a significance of 3.2 standard deviations, and measure the ratios of the suppressed to favored branching fractions R(K) = [22.0 \pm 8.6(stat)\pm 2.6(syst)]\times 10^-3, R^+(K) = [42.6\pm 13.7(stat)\pm 2.8(syst)]\times 10^-3, R^-(K)= [3.8\pm 10.3(stat)\pm 2.7(syst]\times 10^-3, as well as the direct CP-violating asymmetry A(K) = -0.82\pm 0.44(stat)\pm 0.09(syst) of this mode. Corresponding quantities for B^- -> D(-> K^+ pi^-)pi^- decay are also reported.Comment: 8 pages, 1 figure, accepted by Phys.Rev.D Rapid Communications for Publicatio

Search for anomalous t t-bar production in the highly-boosted all-hadronic final state

A search is presented for a massive particle, generically referred to as a Z', decaying into a t t-bar pair. The search focuses on Z' resonances that are sufficiently massive to produce highly Lorentz-boosted top quarks, which yield collimated decay products that are partially or fully merged into single jets. The analysis uses new methods to analyze jet substructure, providing suppression of the non-top multijet backgrounds. The analysis is based on a data sample of proton-proton collisions at a center-of-mass energy of 7 TeV, corresponding to an integrated luminosity of 5 inverse femtobarns. Upper limits in the range of 1 pb are set on the product of the production cross section and branching fraction for a topcolor Z' modeled for several widths, as well as for a Randall--Sundrum Kaluza--Klein gluon. In addition, the results constrain any enhancement in t t-bar production beyond expectations of the standard model for t t-bar invariant masses larger than 1 TeV.Comment: Submitted to the Journal of High Energy Physics; this version includes a minor typo correction that will be submitted as an erratu
