Learning Disabilities and Delinquent Behaviors among Adolescents: A Comparison of Those with and without Comorbidity

Research is inconclusive on whether adolescents with learning disabilities (LD) engage in more delinquency than adolescents without such deficits. Mixed results may result from a failure to account for the effects of co-occurring disabilities. Using the National Longitudinal Study of Adolescent Health, this study examines delinquency among adolescents without disabilities to youth with LD, Attention Disorder Symptoms (ADS), and comorbid LD/ADS. Results indicate no significant differences in property offenses, or alcohol, tobacco, and marijuana use; however, youth with LD reported significantly more violence than non-disabled youth. Findings illustrate the heterogeneous effects various disabilities have on delinquent behavior. Future research and policy implications will be discussed

Understanding the physics of hydrophobic solvation

Simulations of water near extended hydrophobic spherical solutes have revealed the presence of a region of depleted density and accompanying enhanced density fluctuations.The physical origin of both phenomena has remained somewhat obscure. We investigate these effects employing a mesoscopic binding potential analysis, classical density functional theory (DFT) calculations for a simple Lennard-Jones (LJ) solvent and Grand Canonical Monte Carlo (GCMC) simulations of a monatomic water (mw) model. We argue that the density depletion and enhanced fluctuations are near-critical phenomena. Specifically, we show that they can be viewed as remnants of the critical drying surface phase transition that occurs at bulk liquid-vapor coexistence in the macroscopic planar limit, i.e.~as the solute radius $R_s\to\infty$. Focusing on the radial density profile $\rho(r)$ and a sensitive spatial measure of fluctuations, the local compressibility profile $\chi(r)$, our binding potential analysis provides explicit predictions for the manner in which the key features of $\rho(r)$ and $\chi(r)$ scale with $R_s$, the strength of solute-water attraction $\varepsilon_{sf}$, and the deviation from liquid-vapor coexistence of the chemical potential, $\delta\mu$. These scaling predictions are confirmed by our DFT calculations and GCMC simulations. As such our theory provides a firm basis for understanding the physics of hydrophobic solvation.Comment: 18 page

Density depletion and enhanced fluctuations in water near hydrophobic solutes: identifying the underlying physics

We investigate the origin of the density depletion and enhanced density fluctuations that occur in water in the vicinity of an extended hydrophobic solute. We argue that both phenomena are remnants of the critical drying surface phase transition that occurs at liquid-vapor coexistence in the macroscopic planar limit, ie. as the solute radius $R_s\to\infty$. Focusing on the density profile $\rho(r)$ and a sensitive spatial measure of fluctuations, the local compressibility profile $\chi(r)$, we develop a scaling theory which expresses the extent of the density depletion and enhancement in compressibility in terms of $R_s$, the strength of solute-water attraction $\varepsilon_s$, and the deviation from liquid-vapor coexistence $\delta\mu$. Testing the predictions against results of classical density functional theory for a simple solvent and Grand Canonical Monte Carlo simulations of a popular water model, we find that the theory provides a firm physical basis for understanding how water behaves at a hydrophobe.Comment: 5 pages, 4 figures.

Examining the Effectiveness of Marketing Practices of a Nonprofit Institution of Higher Education: Internal Service Provider

Abstract - Quality education is the sum of Institutions of Higher Education’s (IHE) parts, including classroom instruction and internal services, that are key to a student’s success during and after college. The purpose of this study is to address an understudied sector in the nonprofit marketing literature (i.e., Institutions of Higher Education internal service providers). The current study extends Dakouan et al. (2019) work by examining the marketing efforts of an IHE’s career services center’s effectiveness in creating awareness and increasing attendance at career events. The study focuses on outbound marketing strategies addressing the research question “to what extent are outbound marketing strategies successful in creating awareness and increasing attendance at IHE’s career fairs?” Data were collected over three academic years through an intercept survey provided at career fairs and through a database of social media and digital marketing analytics at a medium-sized university located in the Southeastern United States. Frequency analyses were used to determine the effectiveness of marketing strategies in bringing awareness and increasing attendance to IHE career fairs. Further, attendance data were compared between results of frequency analyses of outbound marketing strategies. The findings revealed that only two effective forms of outbound communications used by the subject IHE’s career center were personal selling by faculty and email blast. Findings also revealed that social and internet marketing strategies used by the subject IHE career center were not effective. The results have implications as to a need for continual marketing research of trends in marketing best practices. The findings demonstrated the need for adding inbound marketing strategies(Dakouan et al., 2019) and hiring and/or training staff in marketing research, social media, and internet marketing skills. From the study’s findings, it was concluded that Filip’s(2012) study was supported. Thus, to create awareness and increase attendance at events provided by an IHE’s internal services providers, strategically applied marketing best practices are necessary

Sleep and Delinquency: Does the Amount of Sleep Matter?

Sleep, a key indicator of health, has been linked to a variety of indicators of well-being such that people who get an adequate amount generally experience greater well-being. Further, a lack of sleep has been linked to a wide range of negative developmental outcomes, yet sleep has been largely overlooked among researchers interested in adolescent delinquency. The purpose of this study was to explore the relationship between hours of sleep and delinquent behavior among adolescents by using data from Wave 1 of the National Longitudinal Study of Adolescent Health (n = 14,382; 50.2% female, 63.5% white). A series of negative binomial regressions showed that youth who typically sleep seven or fewer hours per night reported significantly more property delinquency than youth who sleep the recommended 8–10 h. Further, youth who reported sleeping 5 or fewer hours per night reported significantly more violent delinquency than youth who reported sleeping the recommended number of hours per night. The findings suggest that sleep is an important, and overlooked, dimension of delinquent behavior and studies that focus on adolescent health should further investigate the effects of insufficient sleep. Finally, the authors recommend that sleep and other relevant health behaviors be considered in the context of more comprehensive approaches to delinquency prevention and intervention

Candidate Success and edTPA: Looking at the Data

This descriptive study looks at the correlations between Teacher Performance Assessment (edTPA) data and numerous program data points, including GPA, major GPA, and benchmark assignment scores, gathered in an Early Childhood Education (ECE) program. Previous studies have looked to correlate grade point average (GPA) with pre-service teacher performance; however, correlating students’ benchmark assessment scores and student performance on edTPA has not been attempted. This study looks to determine the relationships between overall GPA, major GPA (Early Childhood Education), and edTPA performance (overall score and task scores). Relationships were also investigated between program benchmark assessments (case study, family culture project, integrated investigation unit, student teaching evaluation) and edTPA performance (overall score and task scores). Findings suggest a relationship between overall GPA and edTPA overall score as well as GPA and individual edTPA task scores. In exploring benchmark assignments, correlations were found between the Integrated Investigation Unit and overall edTPA score and edTPA Task 1 and 3 scores

When Agencies and Families Come Together: Dealing with Conflict in Building Partnerships

In età tardoromana e bizantina l'insediamento di Vaste era articolato in una serie di villaggi sparsi nel territorio, intorno all'odierno abitato, le cui tracce sono venute in luce grazie alle ricognizioni dio superficie condotte dall'équipe dell'Università del Salento. In questo sistema insediativo un ruolo di particolare importanza era ricoperto da un edificio di culto, messo in luce nell'area di Fondo Giuliano, nelle vicinanze della cripta dei SS. Stefani. La chiesa presenta diverse fasi costruttive. La prima, il cui impianto è collocabile alla fine del IV sec. d.C., ha pianta cruciforme, con piccola abside, e muro di recinzione. La copertura doveva essere a capriate lignee che sostenevano un tetto di tegole. Nell’edificio è stato riconosciuto un martyrium, ossia un monumento dedicato al culto delle reliquie. Dopo la sua distruzione, forse collegabile agli eventi della guerra greco-gotica (535-553), nella seconda metà del VI secolo fu innalzata una seconda chiesa, la maggiore per dimensioni e certamente la più importante: presenta un impianto a tre navate separate da file di pilastri, con grande abside centrale, e tetto a doppio spiovente. La struttura si inserisce bene nel quadro dell’architettura cristiana di Terra d’Otranto. In epoca altomedievale (VIII-IX sec. d.C.), infine, la struttura subisce una significativa trasformazione: viene riutilizzata l’abside, ma sono escluse le navate laterali con l’innalzamento di muri perimetrali tra i pilastri, cambia completamente l’articolazione dello spazio interno, con la creazione di quattro piccole campate per ciascun lato. In relazione con la fase di vita della prima chiesa, nell’area circostante si estende una grande necropoli rupestre. Di questa è stato indagato il nucleo principale, situato alle spalle dell’edificio e comprendente circa 130 tombe. Le tombe sono scavate nel banco calcareo, all'interno di una cavità artificiale ricavata nel costone roccioso in maniera da formare una necropoli rupestre, assai simile alle catacombe. Le fosse erano coperte con lastroni piani o a doppio spiovente con "acroteri" ai quattro angoli, spesso provvisti di “coppelle”, che servivano durante lo svolgimento del rito del refrigerium, l’offerta di cibi e bevande ai defunti. Le tombe risultano prevalentemente utilizzate per numerose deposizioni, probabilmente in riferimento a gruppi famigliari; alcune fosse di piccole dimensioni ospitano esclusivamente bambini. I corredi sono costituiti da oggetti di ceramica e vetro come brocche, coppe e lucerne, monili (bracciali, collane, orecchini, fibbie) ed oggetto di uso personale (pettini e spilloni). Al rituale di offerta dell’obolo per Caronte fa ancora riferimento la presenza di monete, talora collocate nella bocca del defunto

Point-of-care versus central testing of hemoglobin during large volume blood transfusion.

BACKGROUND: Point-of-care (POC) hemoglobin testing has the potential to revolutionize massive transfusion strategies. No prior studies have compared POC and central laboratory testing of hemoglobin in patients undergoing massive transfusions. METHODS: We retrospectively compared the results of our point-of-care hemoglobin test (EPOC®) to our core laboratory complete blood count (CBC) hemoglobin test (Sysmex XE-5000™) in patients undergoing massive transfusion protocols (MTP) for hemorrhage. One hundred seventy paired samples from 90 patients for whom MTP was activated were collected at a single, tertiary care hospital between 10/2011 and 10/2017. Patients had both an EPOC® and CBC hemoglobin performed within 30 min of each other during the MTP. We assessed the accuracy of EPOC® hemoglobin testing using two variables: interchangeability and clinically significant differences from the CBC. The Clinical Laboratory Improvement Amendments (CLIA) proficiency testing criteria defined interchangeability for measurements. Clinically significant differences between the tests were defined by an expert panel. We examined whether these relationships changed as a function of the hemoglobin measured by the EPOC® and specific patient characteristics. RESULTS: Fifty one percent (86 of 170) of paired samples\u27 hemoglobin results had an absolute difference of ≤7 and 73% (124 of 170) fell within ±1 g/dL of each other. The mean difference between EPOC® and CBC hemoglobin had a bias of - 0.268 g/dL (p = 0.002). When the EPOC® hemoglobin was \u3c 7 g/dL, 30% of the hemoglobin values were within ±7, and 57% were within ±1 g/dL. When the measured EPOC® hemoglobin was ≥7 g/dL, 55% of the EPOC® and CBC hemoglobin values were within ±7, and 76% were within ±1 g/dL. EPOC® and CBC hemoglobin values that were within ±1 g/dL varied by patient population: 77% for cardiac surgery, 58% for general surgery, and 72% for non-surgical patients. CONCLUSIONS: The EPOC® device had minor negative bias, was not interchangeable with the CBC hemoglobin, and was less reliable when the EPOC® value was \u3c 7 g/dL. Clinicians must consider speed versus accuracy, and should check a CBC within 30 min as confirmation when the EPOC® hemoglobin is \u3c 7 g/dL until further prospective trials are performed in this population

Identification of Vehicle Health Assurance Related Trends

Trend analysis in aviation as related to vehicle health management (VHM) was performed by reviewing the most current statistical and prognostics data available from the National Transportation Safety Board (NTSB) accident, the Federal Aviation Administration (FAA) incident, and the NASA Aviation Safety Reporting System (ASRS) incident datasets. In addition, future directions in aviation technology related to VHM research areas were assessed through the Commercial Aviation Safety Team (CAST) Safety Enhancements Reserved for Future Implementations (SERFIs), the National Transportation Safety Board (NTSB) Most-Wanted List and recent open safety recommendations, the National Research Council (NRC) Decadal Survey of Civil Aeronautics, and the Future Aviation Safety Team (FAST) areas of change. Future research direction in the VHM research areas is evidently strong as seen from recent research solicitations from the Naval Air Systems Command (NAVAIR), and VHM-related technologies actively being developed by aviation industry leaders, including GE, Boeing, Airbus, and UTC Aerospace Systems. Given the highly complex VHM systems, modifications can be made in the future so that the Vehicle Systems Safety Technology Project (VSST) technical challenges address inadequate maintenance crew's trainings and skills, and the certification methods of such systems as recommended by the NTSB, NRC, and FAST areas of change
