The Impact of Educational Policy on English Learners in a Rural Indiana School Corporation

Indiana English learners (ELs) constitute a rapidly growing portion of the state’s school-aged population, and those classified as limited English proficient are low performers on the state test. The purpose of this embedded mixed methods study was to understand how school personnel respond to accountability mandates, interpret test scores, and make decisions on behalf of ELs. Interviews were conducted with four administrators and three EL teachers from a rural Indiana school corporation (i.e., school district) with one of the state’s largest EL populations. In addition, four years of student test scores from the corporation were analyzed. Findings indicate that in response to accountability mandates, school personnel implemented numerous changes, including working together to collectively analyze student test scores and ending sheltered English instruction in two schools. This study illustrates the importance of examining both student test scores and the experiences of educational professionals to understand the intended and unintended results of educational policies

An exploration of Indiana's English language learner language programming models

Indiana provides a unique context for the study of English learner (EL) K-12 language program models, as it is home to the nation's second fastest growing EL population (Migration Policy Institute, 2010). Despite exponential growth of the state's EL community, Indiana is one of 15 states that does not require either bilingual or EL preparation for pre-service teachers and school leaders (Tanenbaum et al., 2012). Additionally, the Indiana Department of Education (IDOE) neither expects nor requires teachers who work with ELs to be bilingual or EL-certified. The impetus for this study was the growing demand from Indiana bilingual/EL leaders to understand the variant ways the state's K-12 English language programs were conceptualized and instituted, especially for schools with predominantly Hispanic communities. This study contributes to the limited amount of research on bilingual and EL programming models in Midwestern schools with relatively recent and growing Hispanic populations. The primary purpose of this study was to examine how Indiana's bilingual/EL district leaders implement, negotiate, and perceive the effectiveness of their English language programs. In this survey study, we examined the characteristics of Indiana's bilingual education/English learner (BE/EL) district leaders and how they implement, negotiate, and perceive the effectiveness of their instructional program models for emergent bilinguals (EBs). We developed a survey to investigate the following: 1) the backgrounds and experiences of BE/EL leaders, and 2) the types of bilingual and EL programs implemented by participants' districts. Preliminary findings show that a variety of BE/EL program models operate concurrently even within the same district and that bilingual education programming is rare for emergent bilinguals

A TESOL Service Learning Program in Rural Michigan: An Innovative Approach to Preparing Pre-Service Teachers

Central Michigan University offers a TESOL service learning course that provides pre-service teachers the opportunity to apply their understanding of course content while addressing the needs of school-aged and adult emergent multilinguals. An innovative aspect of the course is that it provides clinical experiences, prior to student teaching, at the university’s English Language Institute and at multiple sites within a rural K-12 school district. To contribute to an understanding of how to prepare pre-service teachers while supporting emergent multilinguals in rural communities, the authors describe the development and research basis of the course, discuss the benefits of the course and how they overcame various challenges, and offer advice for developing similar programs. The authors contend that service learning models can provide unique educational experiences by providing meaningful interactions between diverse student populations and call for additional research on TESOL service learning models in rural contexts

Miniaturized data loggers and computer programming improve seabird risk and damage assessments for marine oil spills in Atlantic Canada

Obtaining useful information on marine birds that can aid in oil spill (and other hydrocarbon release) risk and damage assessments in offshore environments is challenging. Technological innovations in miniaturization have allowed archival data loggers to be deployed successfully on marine birds vulnerable to hydrocarbons on water. A number of species, including murres (both Common, Uria aalge, and Thick-billed, U. lomvia) have been tracked using geolocation devices in eastern Canada, increasing our knowledge of the seasonality and colony-specific nature of their susceptibility to oil on water in offshore hydrocarbon production areas and major shipping lanes. Archival data tags are starting to resolve questions around behaviour of vulnerable seabirds at small spatial scales relevant to oil spill impact modelling, specifically to determine the duration and frequency at which birds fly at sea. Advances in data capture methods using voice activated software have eased the burden on seabird observers who are collecting increasingly more detailed information on seabirds during ship-board and aerial transects. Computer programs that integrate seabird density and bird behaviour have been constructed, all with a goal of creating more credible seabird oil spill risk and damage assessments. In this paper, we discuss how each of these technological and computing innovations can help define critical inputs into seabird risk and damage assessments, and when combined, can provide a more realistic understanding of the impacts to seabirds from any hydrocarbon release

Diurnal Immune Cell Migration Patterns Characterized in the Spaceflight Environment

Daily diurnal immune rhythm shapes biological pathways of organisms and closely aligns with optimizing energy usage in response to environmental light-dark cycles. Immune mobilization depends on diurnal signals to regulate immunity. In spaceflight, disrupted circadian rhythms and immune systems are noted. However, crosstalk between these systems has not been fully characterized. To fill this knowledge gap, we utilized a ground-based model of spaceflight to phenotype diurnal immunity in mice. For this, 24-week-old male and female mice were exposed to a combination of single-housed, acute 15cGy 5-ion GCRsim irradiation and continuous hindlimb unloading for 2 weeks on a light:dark [12hr:12hr] cycle throughout. Blood was collected at 24 hours and 2 weeks post irradiation and flow cytometrically profiled. Additionally, ribo-depleted, bulk RNA sequencing characterized unique, diurnal and sex-specific biosignatures. This work expands our understanding of diurnal immunity which is important to consider for personalized medicine directives for astronauts.

The impact of surgical delay on resectability of colorectal cancer: An international prospective cohort study

AIM: The SARS-CoV-2 pandemic has provided a unique opportunity to explore the impact of surgical delays on cancer resectability. This study aimed to compare resectability for colorectal cancer patients undergoing delayed versus non-delayed surgery. METHODS: This was an international prospective cohort study of consecutive colorectal cancer patients with a decision for curative surgery (January-April 2020). Surgical delay was defined as an operation taking place more than 4 weeks after treatment decision, in a patient who did not receive neoadjuvant therapy. A subgroup analysis explored the effects of delay in elective patients only. The impact of longer delays was explored in a sensitivity analysis. The primary outcome was complete resection, defined as curative resection with an R0 margin. RESULTS: Overall, 5453 patients from 304 hospitals in 47 countries were included, of whom 6.6% (358/5453) did not receive their planned operation. Of the 4304 operated patients without neoadjuvant therapy, 40.5% (1744/4304) were delayed beyond 4 weeks. Delayed patients were more likely to be older, men, more comorbid, have higher body mass index and have rectal cancer and early stage disease. Delayed patients had higher unadjusted rates of complete resection (93.7% vs. 91.9%, P = 0.032) and lower rates of emergency surgery (4.5% vs. 22.5%, P < 0.001). After adjustment, delay was not associated with a lower rate of complete resection (OR 1.18, 95% CI 0.90-1.55, P = 0.224), which was consistent in elective patients only (OR 0.94, 95% CI 0.69-1.27, P = 0.672). Longer delays were not associated with poorer outcomes. CONCLUSION: One in 15 colorectal cancer patients did not receive their planned operation during the first wave of COVID-19. Surgical delay did not appear to compromise resectability, raising the hypothesis that any reduction in long-term survival attributable to delays is likely to be due to micro-metastatic disease

The development and validation of a scoring tool to predict the operative duration of elective laparoscopic cholecystectomy

Background: The ability to accurately predict operative duration has the potential to optimise theatre efficiency and utilisation, thus reducing costs and increasing staff and patient satisfaction. With laparoscopic cholecystectomy being one of the most commonly performed procedures worldwide, a tool to predict operative duration could be extremely beneficial to healthcare organisations. Methods: Data collected from the CholeS study on patients undergoing cholecystectomy in UK and Irish hospitals between 04/2014 and 05/2014 were used to study operative duration. A multivariable binary logistic regression model was produced in order to identify significant independent predictors of long (> 90 min) operations. The resulting model was converted to a risk score, which was subsequently validated on second cohort of patients using ROC curves. Results: After exclusions, data were available for 7227 patients in the derivation (CholeS) cohort. The median operative duration was 60 min (interquartile range 45–85), with 17.7% of operations lasting longer than 90 min. Ten factors were found to be significant independent predictors of operative durations > 90 min, including ASA, age, previous surgical admissions, BMI, gallbladder wall thickness and CBD diameter. A risk score was then produced from these factors, and applied to a cohort of 2405 patients from a tertiary centre for external validation. This returned an area under the ROC curve of 0.708 (SE = 0.013, p  90 min increasing more than eightfold from 5.1 to 41.8% in the extremes of the score. Conclusion: The scoring tool produced in this study was found to be significantly predictive of long operative durations on validation in an external cohort. As such, the tool may have the potential to enable organisations to better organise theatre lists and deliver greater efficiencies in care

Mortality and pulmonary complications in patients undergoing surgery with perioperative SARS-CoV-2 infection: an international cohort study

Background: The impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on postoperative recovery needs to be understood to inform clinical decision making during and after the COVID-19 pandemic. This study reports 30-day mortality and pulmonary complication rates in patients with perioperative SARS-CoV-2 infection. Methods: This international, multicentre, cohort study at 235 hospitals in 24 countries included all patients undergoing surgery who had SARS-CoV-2 infection confirmed within 7 days before or 30 days after surgery. The primary outcome measure was 30-day postoperative mortality and was assessed in all enrolled patients. The main secondary outcome measure was pulmonary complications, defined as pneumonia, acute respiratory distress syndrome, or unexpected postoperative ventilation. Findings: This analysis includes 1128 patients who had surgery between Jan 1 and March 31, 2020, of whom 835 (74·0%) had emergency surgery and 280 (24·8%) had elective surgery. SARS-CoV-2 infection was confirmed preoperatively in 294 (26·1%) patients. 30-day mortality was 23·8% (268 of 1128). Pulmonary complications occurred in 577 (51·2%) of 1128 patients; 30-day mortality in these patients was 38·0% (219 of 577), accounting for 81·7% (219 of 268) of all deaths. In adjusted analyses, 30-day mortality was associated with male sex (odds ratio 1·75 [95% CI 1·28–2·40], p\textless0·0001), age 70 years or older versus younger than 70 years (2·30 [1·65–3·22], p\textless0·0001), American Society of Anesthesiologists grades 3–5 versus grades 1–2 (2·35 [1·57–3·53], p\textless0·0001), malignant versus benign or obstetric diagnosis (1·55 [1·01–2·39], p=0·046), emergency versus elective surgery (1·67 [1·06–2·63], p=0·026), and major versus minor surgery (1·52 [1·01–2·31], p=0·047). Interpretation: Postoperative pulmonary complications occur in half of patients with perioperative SARS-CoV-2 infection and are associated with high mortality. Thresholds for surgery during the COVID-19 pandemic should be higher than during normal practice, particularly in men aged 70 years and older. Consideration should be given for postponing non-urgent procedures and promoting non-operative treatment to delay or avoid the need for surgery.
