The United States Road Assessment Program (usRAP) is a systematic tool that determines areas of risk based on roadways characteristics. To determine the effectiveness of the usRAP tool, three rural two-lane corridors, a US highway, a Kansas highway, and a rural secondary road, were selected for this study. Data collection for the usRAP software included manual speed data collection, system-wide centerline miles and crashes, crash costs, countermeasure costs, and manual roadway coding data every 100 m. The usRAP software evaluated and developed a star rating and a Safer Roads Investment Plan for each corridor.

Background and Purpose: The benefits of tPA (tissue-type plasminogen activator) in acute ischemic stroke are time-dependent. However, delivery of thrombolytic therapy rapidly after hospital arrival was initially occurring infrequently in hospitals in the United States, discrepant with national guidelines. Methods: We evaluated door-to-needle (DTN) times and clinical outcomes among patients with acute ischemic stroke receiving tPA before and after initiation of 2 successive nationwide quality improvement initiatives: Target: Stroke Phase I (2010–2013) and Target: Stroke Phase II (2014–2018) from 913 Get With The Guidelines-Stroke hospitals in the United States between April 2003 and September 2018. Results: Among 154 221 patients receiving tPA within 3 hours of stroke symptom onset (median age 72 years, 50.1% female), median DTN times decreased from 78 minutes (interquartile range, 60–98) preintervention, to 66 minutes (51–87) during Phase I, and 50 minutes (37–66) during Phase II ( P <0.001). Proportions of patients with DTN ≤60 minutes increased from 26.4% to 42.7% to 68.6% ( P <0.001). Proportions of patients with DTN ≤45 minutes increased from 10.1% to 17.7% to 41.4% ( P <0.001). By the end of the second intervention, 75.4% and 51.7% patients achieved 60-minute and 45-minute DTN goals. Compared with the preintervention period, hospitals during the second intervention period (2014–2018) achieved higher rates of tPA use (11.7% versus 5.6%; adjusted odds ratio, 2.43 [95% CI, 2.31–2.56]), lower in-hospital mortality (6.0% versus 10.0%; adjusted odds ratio, 0.69 [0.64–0.73]), fewer bleeding complication (3.4% versus 5.5%; adjusted odds ratio, 0.68 [0.62–0.74]), and higher rates of discharge to home (49.6% versus 35.7%; adjusted odds ratio, 1.43 [1.38–1.50]). Similar findings were found in sensitivity analyses of 185 501 patients receiving tPA within 4.5 hours of symptom onset. Conclusions: A nationwide quality improvement program for acute ischemic stroke was associated with substantial improvement in the timeliness of thrombolytic therapy start, increased thrombolytic treatment, and improved clinical outcomes.

Although studies have identified the importance of the mother–daughter relationship and of familism in Mexican culture, there is little in the literature about the mother–daughter experience after daughters have migrated to the United States. This study explores relationships between three daughters in America and their mothers in Mexico, and describes ways in which interdependence between mothers and daughters can be maintained when they are separated by borders and distance. Data collection included prolonged engagement with participants, field notes, and tape-recorded interviews. Narrative analysis techniques were used. Findings suggest mother–daughter interdependence remains. Some aspects may change, but the mother–daughter connection continues to influence lives and provide emotional and, to a lesser extent, material support in their lives.

Seismographic Network

The origins of the Federation of Digital Seismograph Networks (FDSN) can be traced to the summer of 1984. At that time, GEOSCOPE - the French global network of broadband instruments - was already well under way, and in the United States, the Incorporated Research Institutions for Seismology (IRIS) had just published its Science Plan for Global Seismographic Network (GSN). There was clearly an opportunity and the need to involve scientists from other countries in planning for the future of global seismology. An ad hoc meeting of some ten West European seismologists had been arranged in August during the annual meeting of the European Geophysical Society in Louvain. This may be considered to signify the beginning of widescale international cooperation, even though this particular group eventually became the nucleus of ORFEUS (Observatories and Research Facilities for EUropean Seismology). Rather than taking an active role in deployment of new stations, it chose to focus on the issue of providing the service for data collection and exchange, with an important mission of developing the requisite software.

The present study aimed to compare social studies or equivalent course textbooks in Turkey, the United States, and France (ethics-citizenship education) based on values education content. The study was designed with the holistic multi-case method, a qualitative research approach, and the study data were collected with document analysis. The study group was assigned with criterion sampling, a purposive sampling method. The study data were analyzed with the content analysis technique. The study findings were as follows: Value dimensions in the textbooks employed in the three countries were similar in the self-transcendence value dimension in Turkey and France, while self-enhancement value dimension was identified in the US (New York) textbooks. Analysis of the value types identified in the textbooks of the three countries demonstrated that the achievement category was prominent in Turkish and American (New York) textbooks, while universalism-concern value type was observed in France. Modesty value type was observed the least in the USA (New York) and France textbooks. However, the least frequent category was prestige in Turkish textbooks. The instruction approaches that were frequently observed in the textbook learning-instruction processes in the three countries were similar and the value explanation approach was adopted in Turkish and American (New York) social studies and French ethics-citizenship textbooks. The least frequent value instruction approaches in the textbooks were value instruction by observation in Turkish and French textbooks and moral reasoning method in the American (New York) social studies textbooks. Furthermore, American (New York) textbooks did not employ the value instruction by observation approach.

We have kept our republic through a variety of localized disasters and various problem elections. The research presented here highlights the field of “Election Science and Administration” (ESA). Research in our field maximize our probability of continuing to keep our republic—even in the face of a pandemic which is a national—and international challenge. As the United States and the world deal with the specter of a pandemic election, the growth of the scholarly field designed to advocate for transparency in data collection and to improve the quality of elections is more important than ever.

How do formative reading assessments influence educators’ ability to assess readers’ understandings in culturally responsive ways? This study examines three formative reading assessments to explore the capacity of each measure to fairly represent readers’ understandings without being influenced negatively by social and cultural diversity. The guiding question is “How do these three formative assessments inform and support culturally responsive literacy instruction?” Participants in this study include 10 young adolescent African American male readers. Data collection and analysis took place in a Midwestern urban university in the United States and makes use of a cross case comparison format. Interviews reveal that readers are the best informants regarding their own understandings about texts. Comprehension questions and retellings reveal discrepancies across readers’ understandings. It is crucial that students are given the benefit of responsive assessments in order to accurately demonstrate academic strengths and areas of instructional need.

Meteorological Effects

The estimation of absolute road traffic noise levels without including the effects of meteorology is thought to be a major source of error in the estimation process commonly used in the United States. In response, the Transportation Research Board-sponsored NCHRP 25-52, Meteorological Effects on Roadway Noise, to collect highway noise data under different meteorological conditions, document the meteorological effects on roadway noise propagation under different atmospheric conditions, develop best practices, and provide guidance on how to (a) quantify meteorological effects on roadway noise propagation and (b) explain those effects to the public. The completed project involved collecting and analyzing 35,000 min of sound and meteorological data at 16 barrier and no-barrier measurement positions adjacent to Interstate 17 in Phoenix, Arizona. This report provides information on the data collection and the modeling recommendations. The database assembled is thought to be among the best available in the United States to permit analysis of meteorological effects on roadway noise. The study recommendations will advance the methodology for estimating the meteorological effects on roadway noise in the United States.
