A Geographic Account of Economic, Health, and Educational Disparities in Hartford’s Sheff Region
In the current study, I use geographic techniques to examine the distribution of key housing, economic, health, and educational indicators in metropolitan Hartford. I focus in particular on factors that bear upon the lives of children in this area, also known as the Sheff region—a reference to the long-standing Sheff v. O’Neill school desegregation lawsuit. The results reveal substantial disparities in the geographic distribution of important resources and outcomes across the racially and economically stratified region. Despite earnest school desegregation efforts, the opportunities, access, and resources available to children in municipalities across the metro Hartford region remain starkly different. Children of color living in central Connecticut’s poor urban communities are disproportionately affected by a highly fragmented sociopolitical geography. Recommendations are made for more comprehensive, cross-sector policy interventions as well as regional collaboratives

NEPC Review: Graduation Rates for Choice and Public School Students in Milwaukee, 2003-2008
This review examines a research study that compares high school graduation rates of students who used vouchers to attend private high schools in Milwaukee and students who attended public high schools in that same city. The study reports that for the most recent year of data, a sample of voucher students had estimated graduation rates 12 percentage points higher on average than a sample of public school students. Overall, the trend favoring voucher students was observed in five of the previous six years. The analysis is technically accurate and makes defensible assumptions as necessary for the final calculations. However, although the results are descriptively useful, any real claims about whether the voucher program is actually causing higher graduation rates would depend on a much stronger research design.</p

NEPC Review: The MPCP Longitudinal Educational Growth Study Second Year Report
The study under review is the second-year evaluation report of the Milwaukee Parental Choice Program (MPCP), a publicly funded voucher program that allows low-income students in Milwaukee to attend secular and religious private schools in that city. Its primary finding is that there were no overall statistically significant differences in achievement growth in reading or math between MPCP and Milwaukee Public School (MPS) students over a one-year period. The study design and methods of analysis are sound overall. The relatively short duration of the treatment, however, raises questions about the usefulness of the findings. Correction: On June 24, 2009, the authors of the report under review brought to our attention an error in the original May 28, 2009 review of their work by Casey Cobb. Professor Cobb has revised his review accordingly. In the initial review, Professor Cobb made an incorrect assumption about the sampling procedures used in the study. As a result, he drew the incorrect conclusion that the external validity of the findings was tempered by a non-random sample of MPCP students, and hence a non-representative sample of MPCP schools. As the study authors pointed out, the MPCP sample was in fact drawn randomly.</p

School Choice and Accountability
This policy brief explores the intersection of school choice and accountability. Based on a review of research since 1970, the authors first develop a typology of four distinct models of accountability: bureaucratic, performance, market and professional. They both define these and demonstrate how they are embedded in the school choice movement. Second, they examine several school choice options--vouchers and tax credits, charter schools, virtual/cyber schools, home schools and inter- and intradistrict choice--and detail the varied accountability systems inherent in each. Third, they explore the impact of school choice programs on the accountability of traditional district schools. Finally, they provide practical recommendations for policymakers and other interested parties
Uplifting manhood to wonderful heights? News coverage of the human costs of military conflict from world war I to Gulf war Two
Domestic political support is an important factor constraining the use of American military power around the world. Although the dynamics of war support are thought to reflect a cost-benefit calculus, with costs represented by numbers of friendly war deaths, no previous study has examined how information about friendly, enemy, and civilian casualties is routinely presented to domestic audiences. This paper establishes a baseline measure of historical casualty reporting by examining New York Times coverage of five major wars that occurred over the past century. Despite important between-war differences in the scale of casualties, the use of conscription, the type of warfare, and the use of censorship, the frequency of casualty reporting and the framing of casualty reports has remained fairly consistent over the past 100 years. Casualties are rarely mentioned in American war coverage. When casualties are reported, it is often in ways that minimize or downplay the human costs of war

Overview of the Alliance for Cellular Signaling
The Alliance for Cellular Signaling is a large-scale collaboration designed to answer global questions about signalling networks. Pathways will be studied intensively in two cells-B lymphocytes (the cells of the immune system) and cardiac myocytes-to facilitate quantitative modelling. One goal is to catalyse complementary research in individual laboratories; to facilitate this, all alliance data are freely available for use by the entire research community.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/62977/1/nature01304.pd
Multi-messenger observations of a binary neutron star merger
On 2017 August 17 a binary neutron star coalescence candidate (later designated GW170817) with merger time 12:41:04 UTC was observed through gravitational waves by the Advanced LIGO and Advanced Virgo detectors. The Fermi Gamma-ray Burst Monitor independently detected a gamma-ray burst (GRB 170817A) with a time delay of ~1.7 s with respect to the merger time. From the gravitational-wave signal, the source was initially localized to a sky region of 31 deg2 at a luminosity distance of 40+8-8 Mpc and with component masses consistent with neutron stars. The component masses were later measured to be in the range 0.86 to 2.26 Mo. An extensive observing campaign was launched across the electromagnetic spectrum leading to the discovery of a bright optical transient (SSS17a, now with the IAU identification of AT 2017gfo) in NGC 4993 (at ~40 Mpc) less than 11 hours after the merger by the One- Meter, Two Hemisphere (1M2H) team using the 1 m Swope Telescope. The optical transient was independently detected by multiple teams within an hour. Subsequent observations targeted the object and its environment. Early ultraviolet observations revealed a blue transient that faded within 48 hours. Optical and infrared observations showed a redward evolution over ~10 days. Following early non-detections, X-ray and radio emission were discovered at the transient’s position ~9 and ~16 days, respectively, after the merger. Both the X-ray and radio emission likely arise from a physical process that is distinct from the one that generates the UV/optical/near-infrared emission. No ultra-high-energy gamma-rays and no neutrino candidates consistent with the source were found in follow-up searches. These observations support the hypothesis that GW170817 was produced by the merger of two neutron stars in NGC4993 followed by a short gamma-ray burst (GRB 170817A) and a kilonova/macronova powered by the radioactive decay of r-process nuclei synthesized in the ejecta
