Reducing suspension rates in Camden, New Jersey

Researchers have found that being suspended is a strong indicator that a student will eventually drop out. Students who drop out are much more likely to end up in prison, becoming part of the school to prison pipeline. This study will look to answer the question Are Charter schools addressing the School to Prison Pipeline? Camden, NJ, a city riddled with poverty, high crime rates, and high rates of incarceration is now a city with an all but dismantled public school system. Can Charter schools be the answer? Researchers have gathered enough evidence to support various solutions including but are not limited to parental involvement, restorative justice, and increased teacher training. Continued research and practice on this matter will have great benefits for students, parents and teachers alike. This research integrates a mixed methodology using qualitative data and quantitative data. The setting was chosen because the school boasts a consistent suspension rate lower than its neighboring schools. The school is consistently working to lower the suspension and absentee rates on a year-to-year basis. In studying the school\u27s climate, discipline policies and practices, further best practices may be identified and utilized

Categorical Semantics of Cyber-Physical Systems Theory

Cyber-physical systems require the construction and management of various models to assure their correct, safe, and secure operation. These various models are necessary because of the coupled physical and computational dynamics present in cyber-physical systems. However, to date the different model views of cyber-physical systems are largely related informally, which raises issues with the degree of formal consistency between those various models of requirements, system behavior, and system architecture. We present a category-theoretic framework to make different types of composition explicit in the modeling and analysis of cyber-physical systems, which could assist in verifying the system as a whole. This compositional framework for cyber-physical systems gives rise to unified system models, where system behavior is hierarchically decomposed and related to a system architecture using the systems-as-algebras paradigm. As part of this paradigm, we show that an algebra of (safety) contracts generalizes over the state of the art, providing more uniform mathematical tools for constraining the behavior over a richer set of composite cyber-physical system models, which has the potential of minimizing or eliminating hazardous behavior

Sugary Drink FACTS 2014: Some Progress but Much Room for Improvement in Marketing to Youth

This report updates a 2011 report on the same topic. Using the same methods as the last report, researchers examined changes in the nutritional content of sugar-sweetened drinks including sodas, fruit drinks, flavored waters, sports drinks, iced teas, as well as zero-calorie energy drinks and shots. They also analyzed marketing tactics for 23 companies that advertised these products, including amount spent to advertise in all media; child and teen exposure to advertising and brand appearances on TV and visits to beverage company websites, including differences for black and Hispanic youth; advertising on websites popular with children and teens; and marketing in newer media like mobile apps and social media. Researchers also examined changes in advertising of diet beverages, 100% juice, and water

Features of successful interventions to improve adherence to Inhaled Corticosteroids in children with asthma:A narrative systematic review

INTRODUCTION: Nonadherence to inhaled corticosteroids (ICSs) in children with asthma leads to significant morbidity and mortality. Few adherence interventions have been effective and little is known about what contributes to intervention effectiveness. This systematic review summarizes the efficacy and the characteristics of effective interventions. METHODS: Six databases were systematically searched on October 3, 2020 for randomized control trials measuring adherence to ICS in children with asthma. A narrative synthesis was conducted focusing on intervention efficacy and study reliability. Intervention content was coded based on the National Institute for Health and Care Excellence guidelines for medicines adherence (the Perceptions and Practicalities Approach, PAPA) and behavior change techniques (BCTs), to determine the effective aspects of the intervention. RESULTS: Of 240 studies identified, 25 were eligible for inclusion. Thirteen of the 25 studies were categorized as being highly reliable. Nine of the 13 interventions were effective at increasing adherence and 6 of those met the criteria for a PAPA intervention. Techniques targeting perceptions and practicalities in successful interventions included rewards, reminders, feedback and monitoring of adherence, pharmacological support, instruction on how to take their ICS/adhere, and information about triggers for symptoms and nonadherence. CONCLUSION: Adherence interventions in children with asthma have mixed effectiveness. Effective intervention studies were more frequently of higher quality, were tailored to individuals' perceptual and practical adherence barriers, and used multiple BCTs. However, due to the small number of included studies and varying study design quality, conclusions drawn here are preliminary. Future research is needed to test a PAPA‐based intervention with a rigorous study design

The impact of virtual reality simulation training on operative performance in laparoscopic cholecystectomy: meta-analysis of randomized clinical trials

BACKGROUND: Simulation training can improve the learning curve of surgical trainees. This research aimed to systematically review randomized clinical trials (RCT) evaluating the performance of junior surgical trainees following virtual reality training (VRT) and other training methods in laparoscopic cholecystectomy. METHODS: MEDLINE (PubMed), Embase (Ovid SP), Web of Science, Scopus and LILACS were searched for trials randomizing participants to VRT or no additional training (NAT) or simulation training (ST). Outcomes of interest were the reported performance using global rating scores (GRS), the Objective Structured Assessment of Technical Skill (OSATS) and Global Operative Assessment of Laparoscopic Skills (GOALS), error counts and time to completion of task during laparoscopic cholecystectomy on either porcine models or humans. Study quality was assessed using the Cochrane Risk of Bias Tool. PROSPERO ID: CRD42020208499. RESULTS: A total of 351 titles/abstracts were screened and 96 full texts were reviewed. Eighteen RCT were included and 15 manuscripts had data available for meta-analysis. Thirteen studies compared VRT and NAT, and 4 studies compared VRT and ST. One study compared VRT with NAT and ST and reported GRS only. Meta-analysis showed OSATS score (mean difference (MD) 6.22, 95%CI 3.81 to 8.36, P < 0.001) and time to completion of task (MD -8.35 min, 95%CI 13.10 to 3.60, P = <0.001) significantly improved after VRT compared with NAT. No significant difference was found in GOALS score. No significant differences were found between VRT and ST groups. Intraoperative errors were reported as reduced in VRT groups compared with NAT but were not suitable for meta-analysis. CONCLUSION: Meta-analysis suggests that performance measured by OSATS and time to completion of task is improved with VRT compared with NAT for junior trainee in laparoscopic cholecystectomy. However, conclusions are limited by methodological heterogeneity and more research is needed to quantify the potential benefit to surgical training

The Variation in Morphological Fractions of Perennial Ryegrass Cultivars throughout the Grazing Season and Subsequent Impacts on Organic Matter Digestibility

The grass plant is comprised of leaf blades, leaf sheath (pseudostem), true stem and dead material each differing in digestibility and their relative proportions can impact significantly on sward quality. The objective of this study was to determine the change in the proportion and organic matter digestibility (OMD) of leaf, pseudostem, true stem and dead fractions of four perennial ryegrass cultivars throughout a grazing season
