    Exploring conflict and resolve through quality children\u27s literature

    Get PDF
    This paper explores the value of story structure in offering insights into human conflict and its resolve and in providing bounds in which children can explore these conflicts. A search for quality literature judged appropriate for the intellectual development of middle childhood (ages nine to eleven) will be conducted. The potential offered by these selected works in relating that characters create action and therefore resolve will be investigated

    Oxidation of myoglobin in isolated adult rat cardiac myocytes by 15-hydroperoxy-5,8,11,13-eicosatetraenoic acid

    AbstractThe oxidation of intracellular myoglobin by 15-hydroperoxy-5,8,11,13-eicosatetraenoic acid was studied in suspensions of isolated adult rat heart cells. Myoglobin was converted to a species identified as ferrylMb by its reaction with Na2S to form ferrous sulfmyoglobin. This process was time-dependent and concentration-dependent in a manner consistent with direct accessibility of the exogenous peroxide to the cytosolic protein. The results indicate that myoglobin oxidation may be an early sign of oxidative injury and may limit myocardial function by elimination of this short-term O2 reserve

    Disorder-driven localization and electron interactions in Bix_xTeI thin films

    Strong disorder has a crucial effect on the electronic structure in quantum materials by increasing localization, interactions, and modifying the density of states. Bix_xTeI films grown at room temperature and \SI{230}{K} exhibit dramatic magnetotransport effects due to disorder, localization and electron correlation effects, including a MIT at a composition that depends on growth temperature. The increased disorder caused by growth at 230K causes the conductivity to decrease by several orders of magnitude, for several compositions of Bix_xTeI. The transition from metal to insulator with decreasing composition xx is accompanied by a decrease in the dephasing length which leads to the disappearance of the weak-antilocalization effect. Electron-electron interactions cause low temperature conductivity corrections on the metallic side and Efros-Shklovskii (ES) variable range hopping on the insulating side, effects which are absent in single crystalline Bix_xTeI. The observation of a tunable metal-insulator transition and the associated strong localization and quantum effects in Bix_xTeI shows the possibility of tuning spin transport in quantum materials via disorder.Comment: 7 pages, 4 figure

    The development of a framework for an articulation plan for the transfer of credits from two- to four-year public educational institutions in North Carolina

    It was the purpose of this study to develop a framework for an articulation plan to transfer credits for courses from two- to four-year public educational institutions in North Carolina. In 1981, 109,951 students were enrolled in the 58 institutions in the North Carolina Community College System. The problem precipitating the study was the lack of a plan whereby these students could transfer credits to institutions in the North Carolina University System. Only those students following a prescribed program of study in the College Transfer programs in the 23 community colleges in the system could transfer credits to the University System. A search was made of the education professional literature, and the articulation plans for higher education in other states were studied. Data were solicited through the use of a questionnaire mailed to the chief administrative officer of the two-year public postsecondary institutions in all 50 states. The 43 states (86 percent) from which data were received enrolled approximately 97 percent of students attending public two-year postsecondary educational institutions in the United States as of October, 1981. The states rated their plans using criteria developed by the researcher based on information gathered from the literature

    Testing theories of temporal inferences: Evidence from child language

    Get PDF
    Sentences involving past tense verbs, such as “My dogs were on the carpet”, tend to give rise to the inference that the corresponding present tense version, “My dogs are on the carpet”, is false. This inference is often referred to as a 'cessation 'or 'temporal 'inference, and is generally analyzed as a type of implicature. There are two main proposals for capturing this asymmetry: one assumes a difference in informativity between the past and present counterparts (Altshuler & Schwarzschild 2013), while the other proposes a structural difference between the two (Thomas 2012). The two approaches are similar in terms of empirical coverage, but differ in their predictions for language acquisition. Using a novel animated picture selection paradigm, we investigated these predictions. Specifically, we compared the performance of a group of 4–6-year-old children and a group of adults on temporal inferences, scalar implicatures arising from “some”, and inferences of adverbial modifiers under negation. The results revealed that overall, children computed all three inferences at a lower rate than adult controls; however they were more adult-like on temporal inferences and inferences of adverbial modifiers than on scalar implicatures. We discuss the implications of the findings, both for a developmental alternatives-based hypothesis (e.g., Barner et al. 2011; Singh et al. 2016; Tieu et al. 2016; 2018), as well as theories of temporal inferences, arguing that the finding that children were more (and equally) adult-like on temporal inferences and adverbial modifiers supports a structural theory of temporal inferences along the lines of Thomas (2012)

    Exploring the origins of perpendicular magnetic anisotropy in amorphous Tb-Co via changes in medium-range ordering

    Full text link
    Amorphous thin films of Tb17_{17}Co83_{83} (a-Tb-Co) grown by magnetron co-sputtering exhibit changes in magnetic anisotropy with varying growth and annealing temperatures. The magnetic anisotropy constant increases with increasing growth temperature, which is reduced or vanishes upon annealing at temperatures above the growth temperature. The proposed explanation for this growth-induced anisotropy in high orbital moment Tb-based transition metal alloys such as a-Tb-Co is an amorphous phase texturing with preferential in-plane and out-of-plane local bonding configurations for the rare-earth and transition metal atoms. Scanning nanodiffraction performed in a transmission electron microscope (TEM) is applied to a-Tb17_{17}Co83_{83} films deposited over a range of temperatures to measure relative changes in medium-range ordering (MRO). These measurements reveal an increase in MRO with higher growth temperatures and a decrease in MRO with higher annealing temperatures. The trend in MRO indicates a relationship between the magnetic anisotropy and local atomic ordering. Tilting select films between 0^{\circ} and 40^{\circ} in the TEM measures variations in the local atomic structure a function of orientation within the films. The findings support claims that preferential ordering along the growth direction results from temperature-mediated adatom configurations during deposition, and that oriented MRO correlates with the larger anisotropy constants.Comment: 13 pages, 9 figure
