Developing a Competency-Based Framework to Guide Elementary School Teachers\u27 Efforts in Helping Bullied Children

The current study aimed to develop a competency-based framework designed to assist elementary school teachers in their efforts to help bullied children. Drawing from extant research, Gregus and Cavell (2017) created an initial draft of the framework that contained 25 components representing a mix of knowledge, attitudes, and skills. In Study 1, I obtained input on the framework from practicing elementary school teachers (n = 26) and researchers who study school bullying (n = 14). Teacher input was gathered via a series of focus groups and researchers responded using an online survey. Both teachers and researchers viewed the framework positively and agreed it offers a potentially useful guide for practicing teachers. Thematic analysis of focus group content revealed themes related to knowledge and training about school bullying, beliefs about school bullying, strategies to help bullied children, and challenges teachers face in trying to help bullied children. In Study 2, I asked elementary school teachers (n = 115) to rate the utility and practicality of the competencies as well as their own level of competence in four domains: knowledge, attitudes, foundational skills, and focused skills. Teachers viewed the competencies as essential and realistic. Teachers’ self-ratings of knowledge, attitudes, and skills suggested a reasonably high level of perceived competence. Teachers with higher scores on a measure of self-efficacy in managing school bullying reported higher levels of knowledge, stronger anti-bullying attitudes, and more frequent use of foundational and focused skills. Teachers with more anti-bullying training reported stronger anti-bullying attitudes and more frequent use of focused skills. Teachers with stronger levels of school connectedness reported greater knowledge about bullying. I discuss implications of these findings and the potential for using the framework as a foundation for teacher training and evaluation

Lunch Buddy Mentoring for Bullied Children: Four Case Studies and a Thematic Analysis

Lunch Buddy (LB) mentoring, a type of school-based mentoring, holds promise as a selective intervention for children who are chronically bullied (Elledge, Cavell, Ogle, & Newgent, 2010). This study expanded upon previous research (Elledge et al., 2010) by utilizing a case-study approach combining qualitative and quantitative methods to gain more evidence about the palatability of the intervention and to uncover possible mechanisms by which the intervention is working. Participants were four elementary school children in grades four and five who had been identified as bullied based on child and teacher reports. Quantitative data were collected at multiple points during the course of mentoring, and qualitative interviews with key stakeholders were conducted post-mentoring. Results supported the promise of LB mentoring for bullied children but also revealed outcomes that varied by assessment source and point of assessment. Thematic analysis supported the palatability of LB mentoring and identified factors that could potentially affect the process of mentoring

Real-time, in situ monitoring of surface reactions during plasma passivation of GaAs

Real-time, in situ observations of surface chemistry during the remote plasma passivation of GaAs is reported herein. Using attenuated total reflection Fourier transform infrared spectroscopy, the relative concentrations of -As-O, -As-H, -H2O, and -CH2 bonds are measured as a function of exposure to the effluent from a microwave discharge through NH3, ND3, H2, and D2. The photoluminescence intensity (PL) from the GaAs substrate is monitored simultaneously and used qualitatively to estimate the extent of surface state reduction. It was found that, while the -CHx(x = 2,3) and -As-O concentrations are reduced rapidly, the rates at which the -As-H concentration and the PL intensity increase are relatively slow. The concentration of -H2O on the GaAs surface increases throughout the process as surface arsenic oxides and the silica reactor walls are reduced by atomic hydrogen. These observations suggest that removal of elemental As by reaction with H at the GaAs–oxide interface limits the passivation rate

Az arzén toxicitás metabolikus háttere = The metabolic background of arsenic toxicity

Fő megállapításaink: 1. Az arzenit (AsIII) expozíció növelésével eliminációja metilációval lassul (ezt nem a metildonor-kínálat kimerülése okozza), a szövetekben a glutation (GSH) és az ATP depletálódik, az AsIII retineálódik. Mindezek elősegítik az akut As-expozíció okozta toxicitást. 2. Az arzenát (AsV) a szervezetben sokkal mérgezőbb AsIII-té redukálódik. Ez a folyamat GSH-függő csakúgy, mint az AsIII metilációja és a trivalens arzénvegyületek (AsIII, metilarzenit) biliáris exkréciója GSH-konjugátumként. 3. A gamma-glutamyl transzferáz (GSH-t és GSH-konjugátumokat hidrolizáló enzim) aktivitása nem befolyásolja a GSH-konjugátumot képező trivalens arzénmetabolitok sorsát patkányban. 4. A fenobarbitál-indukció fokozza az AsV redukcióját AsIII-té és az AsIII biliáris exkrécióját. 5. A purin-nukleozid-foszforiláz (PNP) képes az AsV redukciót katalizálni in vitro, mégsem fontos az AsV redukciójában, sem emberi vvt-ben, sem patkányban in vivo. 6. A humán vvt-ben és patkánymáj citoszólban van PNP-független AsV-redukáló mechanizmus is; ez GSH-t, NAD-ot és glikolitikus szubsztrátot igényel. 7. Az AsV glikolízishez kötött redukcióját a gliceraldehid-3-foszfát-dehidrogenáz (GAPDH) katalizálja GSH, NAD és glikolitikus szubsztrát felhasználásával. A GAPDH egyedül felelős az AsV redukciójáért emberi eritrocitákban. 8. A májbeli GAPDH inaktiválásával nyert megfigyeléseink valószínűsítik, hogy a GAPDH részt vesz az AsV redukciójában in vivo is. | Main findings: 1. With increased exposure to arsenite (AsIII), its elimination via methylation slows (not because of compromised methyl donor-availability), tissue glutathione (GSH) as well as ATP become depleted, and AsIII becomes retained. These changes promote toxicity after acute As-exposure. 2. Arsenate (AsV) is reduced in the body to the much more toxic AsIII. This process is GSH dependent, like methylation of AsIII and biliary excretion of trivalent arsenicals (AsIII, methylarsenite) as GSH-conjugates. 3. The activity of gamma-glutamyl transferase (an enzyme hydrolyzing GSH and GSH-conjugates) does not affect the fate of trivalent arsenic metabolites known to form GSH-conjugates. 4. Phenobarbital-induction enhances reduction of AsV to AsIII and the biliary excretion of AsIII. 5. Purine nucleoside phosphorylase (PNP) can catalyze reduction of AsV in vitro, yet it is unimportant in reduction of AsV either in human RBC or in rats in vivo. 6. There is a PNP-independent AsV-reducing mechanism in human RBC and rat liver cytosol; this requires GSH, NAD and glycolytic substrate. 7. The glycolysis-coupled reduction of AsV is catalyzed by glyceraldehyde 3-phosphate dehydrogenase (GAPDH), using GSH, NAD and glycolytic substrate. A GAPDH is solely responsible for reduction of AsV in human erythrocyes. 8. Our observations on rats with inactivated hepatic GAPDH suggest that GAPDH participates in AsV reduction also in vivo
