Timing Matters: How Delaying College Enrollment Affects Earnings Trajectories

High school graduates often delay college enrollment, but few studies have looked at the effects of this choice on their educational attainment and success in the labor market. Using data from the National Longitudinal Survey of Youth 1997, this paper compares the academic and labor market outcomes of high school graduates who delay college enrollment (“delayers”) and those who enroll in college immediately (“on-time enrollees”) up to 13 years after high school completion. The results show that delaying college enrollment decreases individuals’ likelihood of enrolling in college and increases their tendency to enroll in two-year colleges if they do return to school. Delayers experience early earnings benefits, but these fade out after their mid-20s and turn to significant losses over time. Differences in student characteristics only explain one third of the pay gap between delayers and on-time enrollees; 60 percent of the pay gap is explained by delayers’ reduced likelihood of attending and obtaining a degree at a four-year college

Happy Together? The Peer Effects of Dual Enrollment Students on Community College Student Outcomes

Nationally, 15% of first-time community college students were high school students taking college coursework through dual enrollment in the fall of 2010, and the percentage has risen since then. The growing numbers of dual enrollment students at community colleges raises concerns about how high school peers might influence traditionally aged college enrollees. Using administrative data from a large state community college system, this paper examines whether being exposed to a higher percentage of dual enrollment peers influences non-dual enrollment enrollees’ performance in college courses. Focusing on entry-level (or gateway) math and English courses and employing a two-way fixed effects model, the authors find that non-dual enrollment college enrollees exposed to a higher proportion of dual enrollment peers had lower pass rates and grades in gateway courses, higher course repetition, and lower subject persistence

Does Taking a Few Courses at a Community College Improve the Baccalaureate, STEM, and Labor Market Outcomes of Four-Year College Students?

Nationally, 38.5% of the students who began at a four-year college in 2011–12 attended another college within the first six years of college entry, and more than half of these students attended a community college. Eight percent of students who began at a four-year institution took up to 10 credits at a community college during the same period. Given the number of students involved, it is helpful to better understand how this kind of postsecondary enrollment pattern affects students. This paper considers a sample of “supplementally enrolled” students who began in and primarily enrolled in four-year colleges but who also earned limited numbers of credits at community colleges. The authors use student data from the Education Longitudinal Study of 2002 and a propensity score matching approach to compare key outcomes of four-year college students who earned 1 to 10 credits at two-year colleges during their first three years at college with those of four-year college students who never earned credits in a two-year college. Many of the supplementally enrolled students took STEM courses at a two-year college. The supplementally enrolled students had higher STEM and total credits earned, higher bachelor’s degree attainment, and better employment outcomes than the students who never earned credits from a two-year college. Subgroup results also suggest that supplemental enrollment can potentially improve STEM degree attainment outcomes, particularly for low-socioeconomic-status and female students

The Impact of Dual Enrollment on College Application Choice and Admission Success

Dual enrollment is one of the fastest growing programs that support the high school-to-college transition. Yet, there is limited empirical evidence about its impact on either students’ college application choices or admission outcomes. Using a fuzzy regression discontinuity approach and data from two cohorts of ninth-grade students in one anonymous state, the authors of this paper found that taking dual enrollment credits increased the total number of colleges students applied to and the likelihood of applying to any moderately or highly selective in-state four-year institution. Attempting dual enrollment credits also increased the total number of in-state four-year colleges a student got admitted to and the probability of being admitted to a highly selective in-state four-year college. Heterogeneous analysis further indicates that the gains were primarily driven by Black students

Six Years Later: Examining the Academic and Employment Outcomes of the Original and Reinstated Summer Pell

While the Pell Grant covers a substantial proportion of college tuition for low-income students, it has covered only two full-time semesters per year and has not included any support for summer courses through most of its history. As research has shown that continuous enrollment throughout the year increases college persistence and completion, the summer Pell (SP) program was added during the summer of 2009 and allowed eligible low-income students to receive an additional grant for summer tuition and eligible costs. The SP was eliminated in 2011 and then restored in 2017. Using administrative data on community college students in New York City, the authors’ difference-in-differences analysis results from both periods show that SP-eligible students had a higher retention rate in the fall of the second year, had higher associate and bachelor’s degree attainment rates, and had higher earnings gains up to nine years from college entry compared to SP-ineligible students. Heterogeneous analysis indicates that the SP benefits were driven by Black students and older students

High School Dual Enrollment in Florida: Effects on College Outcomes by Race/Ethnicity and Course Modality

This report presents findings on the relationship between taking community college dual enrollment courses—in which high school students earn high school and college credits simultaneously—and college outcomes among Florida public high school students. It analyses dual enrollment course-taking by racial/ethnic group (Black, Hispanic, White) and course modality (face-to-face on-college-campus, face-to-face off-campus, and online). The report includes (1) a descriptive analysis of the demographic characteristics and outcomes of dual enrollment participants and (2) multivariate regression analyses of the associations between dual enrollment participation and college outcomes, controlling for a rich set of student and school characteristics. The analyses use transcript-level unit record data on two cohorts of Florida students who started public high school in 2007 and 2012 and were tracked through high school and into Florida state colleges (community colleges) and universities. The authors find that Florida high school students who took dual enrollment courses were more likely to be White, female, and from more affluent backgrounds than those who did not take dual enrollment courses. They also find that taking dual enrollment courses is associated with better college outcomes for all racial/ethnic groups considered, and that the effects of dual enrollment are mediated by course modality, such that taking courses online is associated with slightly smaller benefits than taking courses face-to-face

Robust estimation of bacterial cell count from optical density

Optical density (OD) is widely used to estimate the density of cells in liquid culture, but cannot be compared between instruments without a standardized calibration protocol and is challenging to relate to actual cell count. We address this with an interlaboratory study comparing three simple, low-cost, and highly accessible OD calibration protocols across 244 laboratories, applied to eight strains of constitutive GFP-expressing E. coli. Based on our results, we recommend calibrating OD to estimated cell count using serial dilution of silica microspheres, which produces highly precise calibration (95.5% of residuals <1.2-fold), is easily assessed for quality control, also assesses instrument effective linear range, and can be combined with fluorescence calibration to obtain units of Molecules of Equivalent Fluorescein (MEFL) per cell, allowing direct comparison and data fusion with flow cytometry measurements: in our study, fluorescence per cell measurements showed only a 1.07-fold mean difference between plate reader and flow cytometry data

Mortality from gastrointestinal congenital anomalies at 264 hospitals in 74 low-income, middle-income, and high-income countries: a multicentre, international, prospective cohort study

Summary Background Congenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally. Many gastrointestinal congenital anomalies are fatal without timely access to neonatal surgical care, but few studies have been done on these conditions in low-income and middle-income countries (LMICs). We compared outcomes of the seven most common gastrointestinal congenital anomalies in low-income, middle-income, and high-income countries globally, and identified factors associated with mortality. Methods We did a multicentre, international prospective cohort study of patients younger than 16 years, presenting to hospital for the first time with oesophageal atresia, congenital diaphragmatic hernia, intestinal atresia, gastroschisis, exomphalos, anorectal malformation, and Hirschsprung’s disease. Recruitment was of consecutive patients for a minimum of 1 month between October, 2018, and April, 2019. We collected data on patient demographics, clinical status, interventions, and outcomes using the REDCap platform. Patients were followed up for 30 days after primary intervention, or 30 days after admission if they did not receive an intervention. The primary outcome was all-cause, in-hospital mortality for all conditions combined and each condition individually, stratified by country income status. We did a complete case analysis. Findings We included 3849 patients with 3975 study conditions (560 with oesophageal atresia, 448 with congenital diaphragmatic hernia, 681 with intestinal atresia, 453 with gastroschisis, 325 with exomphalos, 991 with anorectal malformation, and 517 with Hirschsprung’s disease) from 264 hospitals (89 in high-income countries, 166 in middleincome countries, and nine in low-income countries) in 74 countries. Of the 3849 patients, 2231 (58·0%) were male. Median gestational age at birth was 38 weeks (IQR 36–39) and median bodyweight at presentation was 2·8 kg (2·3–3·3). Mortality among all patients was 37 (39·8%) of 93 in low-income countries, 583 (20·4%) of 2860 in middle-income countries, and 50 (5·6%) of 896 in high-income countries (p<0·0001 between all country income groups). Gastroschisis had the greatest difference in mortality between country income strata (nine [90·0%] of ten in lowincome countries, 97 [31·9%] of 304 in middle-income countries, and two [1·4%] of 139 in high-income countries; p≤0·0001 between all country income groups). Factors significantly associated with higher mortality for all patients combined included country income status (low-income vs high-income countries, risk ratio 2·78 [95% CI 1·88–4·11], p<0·0001; middle-income vs high-income countries, 2·11 [1·59–2·79], p<0·0001), sepsis at presentation (1·20 [1·04–1·40], p=0·016), higher American Society of Anesthesiologists (ASA) score at primary intervention (ASA 4–5 vs ASA 1–2, 1·82 [1·40–2·35], p<0·0001; ASA 3 vs ASA 1–2, 1·58, [1·30–1·92], p<0·0001]), surgical safety checklist not used (1·39 [1·02–1·90], p=0·035), and ventilation or parenteral nutrition unavailable when needed (ventilation 1·96, [1·41–2·71], p=0·0001; parenteral nutrition 1·35, [1·05–1·74], p=0·018). Administration of parenteral nutrition (0·61, [0·47–0·79], p=0·0002) and use of a peripherally inserted central catheter (0·65 [0·50–0·86], p=0·0024) or percutaneous central line (0·69 [0·48–1·00], p=0·049) were associated with lower mortality. Interpretation Unacceptable differences in mortality exist for gastrointestinal congenital anomalies between lowincome, middle-income, and high-income countries. Improving access to quality neonatal surgical care in LMICs will be vital to achieve Sustainable Development Goal 3.2 of ending preventable deaths in neonates and children younger than 5 years by 2030

Students’ interaction anxiety and social phobia in interprofessional education in Hong Kong: mapping a new research direction

AbstractBackground Interprofessional education (IPE) has been promoted as a breakthrough in healthcare because of the impact when professionals work as a team. However, despite its inception dating back to the 1960s, its science has taken a long time to advance. There is a need to theorize IPE to cultivate creative insights for a nuanced understanding of IPE. This study aims to propose a research agenda on social interaction by understanding the measurement scales used and guiding researchers to contribute to the discussion of social processes in IPE.Method This quantitative research was undertaken in a cross-institutional IPE involving 925 healthcare students (Medicine, Nursing, Social Work, Chinese Medicine, Pharmacy, Speech Language Pathology, Clinical Psychology, Food and Nutritional Science and Physiotherapy) from two institutions in Hong Kong. Participants completed the Social Interaction Anxiety Scale (SIAS-6) and Social Phobia Scale (SPS-6). We applied a construct validation approach: within-network and between-network validation. We performed confirmatory factors analysis, t-test, analysis of variance and regression analysis.Results CFA results indicated that current data fit the a priori model providing support to within-network validity [RMSEA=.08, NFI=.959, CFI=.965, IFI=.965, TLI=.955]. The criteria for acceptable fit were met. The scales were invariant between genders, across year levels and disciplines. Results indicated that social interaction anxiety and social phobia negatively predicted behavioural engagement (F = 25.093, p<.001, R2=.065) and positively predicted behavioural disaffection (F = 22.169, p<.001, R2=.057) to IPE, suggesting between-network validity.Conclusions Our data provided support for the validity of the scales when used among healthcare students in Hong Kong. SIAS-6 and SPS-6 have sound psychometric properties based on students’ data in Hong Kong. We identified quantitative, qualitative and mixed methods research designs to guide researchers in getting involved in the discussion of students’ social interactions in IPE.Key MessagesThe Social Anxiety Scale (SIAS-6) and Social Phobia Scale (SPS-6) scales have sound psychometric properties based on the large-scale healthcare students’ data in IPE in Hong Kong.Social interaction anxiety and social phobia negatively predicted students’ behavioural engagement with IPE and positively predicted behavioural disaffection. The scales are invariant in terms of gender, year level and discipline.Quantitative, qualitative and mixed methods studies are proposed to aid researchers to contribute in healthcare education literature using the SIAS-6 and SPS-6
