A study of the effects of attribution retraining and cognitive self-instruction upon the academic and attentional skills, and cognitive-behavioral trends of elementary-age children served in self-contained learning disabilities programs

The purpose of this study was to investigate the integration of an attribution retraining program and a cognitive self-instruction procedure as a means of improving the academic performance and component attentional skills and modifying the cognitive-behavioral beliefs and behaviors of elementary-age children served in self-contained learning disabilities (SCLD) programs.;Subjects were 77 children, 10-13 years of age, served in public school SCLD programs. A primary group (n = 27) received attributional retraining and cognitive self-instruction, a secondary group (n = 25) cognitive self-instruction alone, and a control group (n = 25) traditional instruction. Intervention in the treatment conditions was presented over the 10-week period in three phases: (a) Controlled Instruction, (b) Transition, and (c) Direct Instruction.;Assessment was conducted in reading, mathematics, and written language on a standardized instrument (Woodcock-Johnson Test of Achievement) and probe sheets, locus of control (Children\u27s Nowicki-Strickland Internal-External control scale), cognitive-behavioral trends (Burks\u27 Behavior Rating Scales), general attention (Visual-Aural Digit Span Test), and attentional style (Matching Familiar Figures Test).;Analysis of covariance and post hoc least squares means analysis revealed significant primary treatment growth in cognitive-behavioral outcomes (poor attention, poor ego strength, and excessive dependency) and probe sheet mathematics; significant primary treatment growth versus either secondary treatment or control conditions was noted in cognitive-behavioral areas (poor academics and poor impulse control) and standardized reading. No significant differences were noted in mathematics or written language on the standardized instrument, reading or written language on probe sheets, trends toward internality, general attention/memory, and latency (near significant) or error rate.;Recommendations include longer term investigations of antecedent attributions, clarification of the role of attribution in cognitive-behavioral change, and a diverse application of attribution retraining in education

Ram booster

The present invention is a space launch system and method to propel a payload bearing craft into earth orbit. The invention has two, or preferably, three stages. The upper stage has rocket engines capable of carrying a payload to orbit and provides the capability of releasably attaching to the lower, or preferably, middle stage. Similar to the lower stage, the middle stage is a reusable booster stage that employs all air breathing engines, is recoverable, and can be turned-around in a short time between missions

Electrochemical Characterization of Precious Metal Braze Alloys Using Potentiodynamic Polarization

This study aimed to characterize the electrochemical behavior of six precious metal braze alloys by performing potentiodynamic polarization tests (ParStat 2273) based on ASTM Specifications G5 and G59. To determine the extent to which the alloys will contribute to galvanic corrosion in a marine environment (3.5 wt% NaCl), corrosion analysis software was used to produce fitted Tafel lines to determine the open circuit potential, Voc, for each alloy. The Voc values for the alloys were found to be -66.58 mV for Gold ABA, 13.01 mV for Nicoro®, -39.00 mV for Nioro®, 23.4 mV for Palniro-1®, -47.91 mV for Palniro-7®, and -205.16 mV for Silver ABA. These values were compared to industry-standard base materials typically used in brazing processes to determine their compatibility as galvanic couples. Differences in Voc greater than 250 mV within the couple are considered unsuitable for joining without additional galvanic protection. To provide coupling recommendations, 95% confidence intervals were made to estimate each alloy’s Voc

Human papillomavirus 16 L2 inhibits the transcriptional activation function, but not the DNA replication function, of HPV-16 E2

In this study we analysed the outcome of the interaction between HPV-16 L2 and E2 on the transactivation and DNA replication functions of E2. When E2 was expressed on its own, it transactivated a number of E2-responsive promoters but co-expression of L2 led to the down-regulation of the transcription transactivation activity of the E2 protein. This repression is not mediated by an increased degradation of the E2 protein. In contrast, the expression of L2 had no effect on the ability of E2 to activate DNA replication in association with the viral replication factor E1. Deletion mutagenesis identified L2 domains responsible for binding to E2 (first 50 N-terminus amino acid residues) and down-regulating its transactivation function (residues 301–400). The results demonstrate that L2 selectively inhibits the transcriptional activation property of E2 and that there is a direct interaction between the two proteins, although this is not sufficient to mediate the transcriptional repression. The consequences of the L2–E2 interaction for the viral life cycle are discussed

Electrochemical oxidation of phosphatidylethanolamines studied by mass spectrometry

Phosphatidylethanolamines (PEs) are widely present in cellular membranes and lipoproteins. Oxidation of PE fatty acyl chains generates several oxidized products, exerting a vast number of biological functions, not totally unveiled yet. In vitro biomimetic models have been used to identify oxidized PEs and to develop analytical strategies for their targeted detection in vivo. Most of the models are based on oxidation by reactive oxygen species (ROS), but the oxidative metabolism of PE also relies on controlled reactions catalyzed by enzymes as lipoxygenase, which can be mimicked by electrochemical (EC) oxidation. In this study, 3 PE standards (1‐palmitoyl‐2‐oleoyl‐sn‐glycero‐3‐phosphoethanolamine (POPE), 1‐palmitoyl‐2‐linoleoyl‐sn‐glycero‐3‐phosphoethanolamine (PLPE), and 1‐palmitoyl‐2‐arachidonoyl‐sn‐glycero‐3‐phosphoethanolamine (PAPE)) were oxidized by EC oxidation, using an EC flow‐through cell system as a biomimetic model of oxidative injury. The new oxidation products were identified by online EC electrospray ionization mass spectrometry (EC‐ESI‐MS and MS/MS). Long‐chain and short‐chain oxidation products were identified, bearing modifications in the sn‐2 acyl chains, whereas the oxidation pattern was dependent on the unsaturation level. Long‐chain oxidation products of PEs (keto, hydroxy, hydroperoxy, poly‐hydroperoxy derivatives) were identified, bearing up to 5, 7, and 10 oxygens for POPE, PLPE, and PAPE, respectively. Fourteen short‐chain oxidation products, 7 from PLPE, and 7 from PAPE, including aldehydes, γ‐hydroxy‐α,β‐aldehydes, and dicarboxylic acids were characterized. Some of these oxidized species were previously reported during the oxidative metabolism of PEs driven by ROS. The EC‐ESI‐MS platform was, therefore, able to mimic the oxidative metabolism of PEs mediated by ROS.publishe
