- Abstract
The 2019 edition of the "Digest of Education Statistics" is the 55th in a series of publications initiated in 1962. The purpose of the "Digest" is to provide a compilation of statistical information covering the broad field of American education from prekindergarten through graduate school. It contains data on a variety of topics, including the number of schools and colleges, teachers, enrollments, and graduates, in addition to educational attainment, finances, and federal funds for education, libraries, and international comparisons. Seven chapters are included: (1) All Levels of Education; (2) Elementary and Secondary Education; (3) Postsecondary Education; (4) Federal Funds for Education and Related Activities; (5) Outcomes of Education; (6) International Comparisons of Education; and (7) Libraries and Use of Technology. Each chapter is divided into a number of topical subsections. Preceding the seven chapters is an introduction that provides a brief overview of current trends in American education, which supplements the tabular materials in chapters 1 through 7. The "Digest" concludes with two appendixes. The first appendix, Guide to Sources, provides a brief synopsis of the surveys used to generate the "Digest" tables; the second, Definitions, is included to help readers understand terms used in the "Digest."

- Abstract
This report uses statistics to examine current conditions and changes over time in education activities and outcomes for different racial/ethnic groups in the United States. The indicators in this report show that some traditionally disadvantaged racial/ethnic groups have made strides in educational achievement, but that gaps still persist. The primary focus of this report is to examine differences in educational participation and attainment of students in the racial/ethnic groups of White, Black, Hispanic, Asian, Native Hawaiian or Other Pacific Islander, American Indian/Alaska Native, and Two or more races. The secondary focus of this report is to illustrate the changing demographics in the United States. Measuring population growth and diversity is important for anticipating the needs of schools and teachers. This report shows that over time, students in these racial/ethnic groups have completed high school and continued their education in college in increasing numbers. Despite these gains, the rate of progress has varied among these racial/ethnic groups and differences by race/ethnicity persist in terms of increases in attainment and progress on key indicators of educational performance. It uses the most recent data available and reports on demographics, preprimary, elementary, and secondary education participation, student achievement, student behaviors and persistence, postsecondary education, and outcomes of education.

- Abstract
The nation's schools should be safe havens for teaching and learning, free of crime and violence. Any instance of crime or violence at school not only affects the individuals involved, but also may disrupt the educational process and affect bystanders, the school itself, and the surrounding community. Establishing reliable indicators of the current state of school crime and safety across the nation and regularly updating and monitoring these indicators are important in ensuring the safety of our nation's students. This is the aim of "Indicators of School Crime and Safety." This report is the 19th in a series of annual publications produced jointly by the National Center for Education Statistics (NCES), Institute of Education Sciences (IES), in the U.S. Department of Education, and the Bureau of Justice Statistics (BJS) in the U.S. Department of Justice. This report presents the most recent data available on school crime and student safety. The indicators in this report are based on information drawn from a variety of data sources, including national surveys of students, teachers, principals, and postsecondary institutions. The information presented in this report serves as a reference for policymakers and practitioners so that they can develop effective programs and policies aimed at violence and school crime prevention. Accurate information about the nature, extent, and scope of the problem being addressed is essential for developing effective programs and policies. This report covers topics such as victimization, teacher injury, bullying and cyber-bullying, school conditions, fights, weapons, availability and student use of drugs and alcohol, student perceptions of personal safety at school, and criminal incidents at postsecondary institutions. Indicators of crime and safety are compared across different population subgroups and over time. Data on crimes that occur away from school are offered as a point of comparison where available. The following are appended: (1) Technical Notes; and (2) Glossary of Terms. Supplemental tables are included. [For the previous report: "Indicators of School Crime: 2015.

- Abstract
"Status and Trends in the Education of Racial and Ethnic Groups" examines the educational progress and challenges students face in the United States by race/ethnicity. This report shows that, over time, students in the racial/ethnic groups of White, Black, Hispanic, Asian, Native Hawaiian or Other Pacific Islander, American Indian/Alaska Native, and Two or more races have completed high school and continued their education in college in increasing numbers. Despite these gains, the rate of progress has varied among these racial/ethnic groups and differences by race/ethnicity persist in terms of increases in attainment and progress on key indicators of educational performance. The report begins with demographic information (Chapter 1) and then is organized roughly according to the chronology of an individual's education, starting with indicators on preprimary, elementary, and secondary participation (Chapter 2), and continuing with student achievement (Chapter 3), student behaviors and persistence in education (Chapter 4), postsecondary education (Chapter 5), and outcomes of education (Chapter 6). A guide to sources and a glossary are appended.

- Abstract
Young children experience various types of early care and education environments the year before they enter kindergarten. Some children attend center-based arrangements such as preschools, childcare centers, or Head Start programs, while others are cared for in relatives' or nonrelatives' homes or are normally cared for only by their parents. Prior research indicates that children's participation rates in specific types of primary care arrangements and their knowledge and skills at kindergarten entry differ in relation to certain characteristics of children and their families, including age at kindergarten entry, race/ethnicity, primary home language, and mother's educational attainment. This Statistical Analysis Report builds upon prior work by using the most recently available data to explore relationships between children's primary care and education arrangements the year before kindergarten and their academic skills and learning behaviors at kindergarten entry, after accounting for child and family background characteristics. In the report, ECE arrangements are classified into five groups: (1) center-based care (including day care centers, Head Start programs, preschools, prekindergartens, and other early childhood programs); (2) home-based relative care; (3) home-based nonrelative care; (4) multiple arrangements (i.e., children who spent an equal amount of time in each of two or more types of arrangements); and (5) no ECE arrangement on a regular basis (i.e., children who had no regularly scheduled care arrangement and mainly received care only from their parents). Information for this report comes from the nationally representative National Household Education Surveys Program (NHES) and the Early Childhood Longitudinal Study, Kindergarten Class of 2010-11 (ECLS-K:2011) data collections. Data from the NHES cross-sectional sample survey are used to describe trends in participation in ECE arrangements that children experience prior to kindergarten entry. The NHES Early Childhood Program Participation (ECPP) surveys gather information on children's participation in ECE programs and the characteristics of these arrangements. Parents reported information on their child's participation in different types of ECE arrangements in 1995, 2001, 2005, and 2012. This report compares estimates of 4- and 5-year-old children's primary ECE arrangements prior to kindergarten entry in 1995 and 2012. Estimates are presented overall and by children's race/ethnicity, their family's poverty status, and their mother's educational attainment. Data from the ECLS-K:2011 longitudinal sample survey are used to explore relationships between primary ECE arrangements the year before kindergarten and academic skills and learning behaviors at kindergarten entry. The ECLS-K:2011 collects detailed information on the school achievement and experiences of students from the 2010-11 kindergarten school year through the spring of 2016, when most of them are expected to be in fifth grade. In the fall of 2010 and spring of 2011, parents reported information on child and family characteristics and their child's participation in ECE settings the year before kindergarten; children were assessed in reading, mathematics, and cognitive flexibility; and kindergarten teachers reported on children's approaches to learning. The report describes the distribution of primary ECE arrangements that first-time kindergartners attended in the year before entering kindergarten in the fall of 2010, including differences in primary ECE arrangements by characteristics of children and their families. The report also describes differences in first-time kindergartners' academic knowledge, skills, and learning behaviors at kindergarten entry relative to their primary ECE arrangement, after accounting for children's sex, age at kindergarten entry, race/ethnicity, family type, primary home language, and socioeconomic status (SES). The following are appended: (1) Reference tables; and (2) Technical Notes and Methodology: (a) National Household Education Surveys Program (NHES); (b) Early Childhood Longitudinal Study, Kindergarten Class of 2010-11 (ECLS-K:2011); and (c) Statistical Procedures.

- Abstract
Our nation's schools should be safe havens for teaching and learning, free of crime and violence. Any instance of crime or violence at school not only affects the individuals involved, but also may disrupt the educational process and affect bystanders, the school itself, and the surrounding community (Brookmeyer, Fanti, and Henrich 2006; Goldstein, Young, and Boyd 2008). Establishing reliable indicators of the current state of school crime and safety across the nation and regularly updating and monitoring these indicators are important in ensuring the safety of our nation's students. This is the aim of "Indicators of School Crime and Safety." This report is the eighteenth in a series of annual publications produced jointly by the National Center for Education Statistics (NCES), Institute of Education Sciences (IES), in the U.S. Department of Education, and the Bureau of Justice Statistics (BJS) in the U.S. Department of Justice. This report presents the most recent data available on school crime and student safety. The indicators in this report are based on information drawn from a variety of data sources, including national surveys of students, teachers, principals, and postsecondary institutions. Sources include results from the School-Associated Violent Deaths Study, sponsored by the U.S. Department of Education, the Department of Justice, and the Centers for Disease Control and Prevention (CDC); the National Crime Victimization Survey and School Crime Supplement to that survey, sponsored by BJS and NCES, respectively; the Youth Risk Behavior Survey, sponsored by the CDC; the Schools and Staffing Survey, School Survey on Crime and Safety, Fast Response Survey System, EDFacts, and High School Longitudinal Study of 2009, all sponsored by NCES; the Supplementary Homicide Reports, sponsored by the Federal Bureau of Investigation; the Campus Safety and Security Survey and Civil Rights Data Collection, both sponsored by the U.S. Department of Education; and the Census of Juveniles in Residential Placement, sponsored by the U.S. Department of Justice. The most recent data collection for each indicator varied by survey, from 2009 to 2014. Each data source has an independent sample design, data collection method, and questionnaire design, or is the result of a universe data collection. Findings described in this report with comparative language (e.g., higher, lower, increase, and decrease) are statistically significant at the 0.05 level. This report covers topics such as victimization, teacher injury, bullying and cyber-bullying, school conditions, fights, weapons, availability and student use of drugs and alcohol, student perceptions of personal safety at school, and criminal incidents at postsecondary institutions. Indicators of crime and safety are compared across different population subgroups and over time. Data on crimes that occur away from school are offered as a point of comparison where available. Preliminary data show that there were 53 school associated violent deaths from July 1, 2012, through June 30, 2013. (Indicator 1). In 2014, among students ages 12-18, there were about 850,100 nonfatal victimizations at school, which included 363,700 theft victimizations and 486,400 violent victimizations (simple assault and serious violent victimizations.) (Indicator 2). During the 2013-14 school year, there were 1.3 million reported discipline incidents in the United States for reasons related to alcohol, drugs, violence, or weapons possession that resulted in a student being removed from the education setting for at least an entire school day. (Indicator 19). Of the 781 total hate crimes reported on college campuses in 2013, the most common type of hate crime reported by institutions was destruction, damage, and vandalism (364 incidents), followed by intimidation (295 incidents) and simple assault (89 incidents; Indicator 23). Additional information about methodology and the datasets analyzed in this report may be found in appendix A. A Glossary of terms is also included in appendix B.

Dysfunctional work environments are characterized by the presence of psycho-social risks, such as workplace bullying (WB): hostile, systematic, and planned behaviors toward other workers in order to get them to leave the organization they work for. The aims of this study are (1) to analyze the prevalence of WB in a sample of teachers and (2) to determine the relationship between socio-demographic and socio-labor variables in relation to three study groups: teacher victims of WB, violent behaviors, and null or low violence. The sample consists of 3442 teachers working in publicly regulated educational centers located in the province of Valencia (Spain). Estimated frequencies, cross-tabulations, and effect sizes were analyzed using SPSS 24. The following results were obtained: (1) 12.26% were potential WB cases, and (2) potential victims of WB were not influenced by the socio-demographic and socio-labor variables proposed. The results obtained did not make it possible to determine a single profile of a teacher victim of WB. It is recommended that training protocols be developed to help teachers recognize and manage WB more effectively. This will improve their health, well-being, and performance in educational centers.

Existing research suggests that victimization risk is higher among urban residents. Violence against women is a notable exception in this trend. While the literature does indicate that rural women are at equal risk for violent victimization, it does not differentiate between types of non-urban spaces (exurbs, suburbs, small towns, dispersed rural). We use a five-category measure of rural-urban location articulated land use to disentangle victim–offender relationship distribution using a female victim sample from the 1996–2005 United States National Crime Victimization Survey (NCVS). In the most rural areas (dispersed rural locations), women are most likely to be victimized by friends or acquaintances. The proportion of women victimized by strangers in dispersed rural locations is very low. As urbanicity increases, so does the proportion of women victimized by strangers. The findings indicate that victim–offender relationships may be dictated by proximity. In dispersed rural locations, there are comparatively fewer people unknown to the victim than in central city locations. Consequently, proximity dictates that offenders in dispersed rural locations are unlikely to be strangers. The articulated land use measure ensures that the differences between types of rural and suburban locations are identified. Future research should consider the impact of proximity on rural victimization and increased specificity in rural measurements. [ABSTRACT FROM AUTHOR]

Research has shown that the development of cognitive and social skills in preschool predicts school readiness in kindergarten. However, most longitudinal studies are short-term, tracking children's development only through the early elementary school years. This study aims to investigate the long-term impact of preschool predictors, intelligence, and mothers' education on grade six school performance. This study presents the results of an eight-year-long longitudinal study. The sample includes 202 Hungarian children (89 boys) from a disadvantaged region of southeastern Hungary. The independent variables were the preschool measures: DIFER (Diagnostic System for Assessing Development), a widely used, standardized school readiness test that measures cognitive and social skills; the Raven intelligence test; and socioeconomic status. The dependent variables in grade six were: National Standardized tests in math and reading (NABC, National Assessment of Basic Competencies) and school grades (GPA). Cronbach's alpha reliability of each test is above 0.76. Correlations and a series of multiple regressions were used for analysis. All three independent variables have significant predictive power for school performance in sixth grade. DIFER skills were the best predictors for reading achievement, intelligence for math achievement, and GPA was best predicted by mothers' education. The results show that developing preschool skills, mothers' education and IQ in preschool are essential to long-term learning success. [ABSTRACT FROM AUTHOR]

Purpose: The low sensitivity and false-negative results of nucleic acid testing greatly affect its performance in diagnosing and discharging patients with coronavirus disease (COVID-19). Chest computed tomography (CT)-based evaluation of pneumonia may indicate a need for isolation. Therefore, this radiologic modality plays an important role in managing patients with suspected COVID-19. Meanwhile, deep learning (DL) technology has been successful in detecting various imaging features of chest CT. This study applied a novel DL technique to standardize the discharge criteria of COVID-19 patients with consecutive negative respiratory pathogen nucleic acid test results at a "square cabin" hospital.Patients and Methods: DL was used to evaluate the chest CT scans of 270 hospitalized COVID-19 patients who had two consecutive negative nucleic acid tests (sampling interval >1 day). The CT scans evaluated were obtained after the patients' second negative test result. The standard criterion determined by DL for patient discharge was a total volume ratio of lesion to lung <50%.Results: The mean number of days between hospitalization and DL was 14.3 (± 2.4). The average intersection over union was 0.7894. Two hundred and thirteen (78.9%) patients exhibited pneumonia, of whom 54.0% (115/213) had mild interstitial fibrosis. Twenty-one, 33, and 4 cases exhibited vascular enlargement, pleural thickening, and mediastinal lymphadenopathy, respectively. Of the latter, 18.8% (40/213) had a total volume ratio of lesions to lung ≥50% according to our severity scale and were monitored continuously in the hospital. Three cases had a positive follow-up nucleic acid test during hospitalization. None of the 230 discharged cases later tested positive or exhibited pneumonia progression.Conclusion: The novel DL enables the accurate management of hospitalized patients with COVID-19 and can help avoid cluster transmission or exacerbation in patients with false-negative acid test.

16. Color-Blind Contradictions and Black/White Binaries: White Academics Upholding Whiteness.

Brooks-Immel, Demerris R. and Murray, Susan B.
- Abstract
This qualitative study maps 'locally situated' (Twine and Gallagher 2008), contours of whiteness as cultural practice and institutional discourse by examining how white college faculty, staff, and administrators respond to multiracial educational environments and multicultural ideals. Drawing on in depth interviews with thirty white administrators, faculty, and staff, this study finds that these white educators adhered to an intermittent form of color-blind racism (Bonilla-Silva 2009) that enabled them to hold fast to the fiction that race has no meaning in their lives, yet remains the single-most defining dimension of the lives of people of color. This analysis identifies five contextually-embedded manifestations of everyday racism and microconstructions of white supremacy: 1) Whites subscribe to a view of racism as an individualized phenomenon, 2) Whites take a color-blind position regarding race in their daily lives, 3) Whites claim, 'people of color see race, but I do not,' 4) Whites only see race as relevant when called to articulate diversity discourse, 5) Whites see race primarily as a black/white binary. Article concludes with implications of findings for critical multiculturalism. [ABSTRACT FROM AUTHOR]

School culture and violence have garnered much public and scholarly attention in recent years. Research in the area has focused on the extent to which strict enforcement of school policies and the law results in safer schools. Other research focuses on providing more supportive, less enforcement-oriented environments for students. We advance this work by using a sample of 2092 respondents from public schools in the United States from the 2015–2016 school survey on crime and safety from the Department of Education. There were several statistically significant supportive practices that reduced violent incidents and disciplinary actions for violence, and the findings generally suggest that punitive policies were not effective in increasing campus safety while controlling for relevant security practices and school contextual variables.

The broiler chamber is powered by two negative pressure fans. The fans are designed with different frequencies for the ventilation system according to the specific air temperature in the broiler chamber. The simulation of ventilation in the empty chamber involved five working conditions in this research. The simulation of ventilation in the broiler chamber and the simulation of the age of air were carried out under three working conditions. According to the measured dimensions of the broiler chamber, a three-dimensional model of the broiler chamber was constructed, and then the model was simplified and meshed in ICEM CFD (integrated computer engineering and manufacturing code for computational fluid dynamics). Two models, i.e., the empty chamber mesh model and the chamber mesh model with block model, were imported in the Fluent software for calculation. In the experiment, 15 measurement points were selected to obtain the simulated and measured values of wind velocity. For the acquired data on wind velocity, the root mean square error (RMSE) was 19.1% and the maximum absolute error was 0.27 m/s, which verified the accuracy of the CFD model in simulating the ventilation system of the broiler chamber. The boundary conditions were further applied to the broiler chamber model to simulate the wind velocity and the age of air. The simulation results show that, when the temperature was between 32 and 34 °C, the average wind velocity on the plane of the corresponding broiler chamber (Y = 0.2 m) was higher than 0.8 m/s, which meets the requirement of comfortable breeding. At the lowest frequency of the fan, the oldest age of air was less than 150 s, which meets the basic requirement for broiler chamber design. An optimization idea is proposed for the age of air analysis under three working conditions to improve the structure of this smart broiler chamber. [ABSTRACT FROM AUTHOR]
