    Following the global COVID-19 pandemic, schools across the United States experimented with online learning platforms. Prior to that, hundreds of schools adopted the Summit Learning platform, meant to supplement face-to-face learning with digital instruction and curricula. This study is a qualitative phenomenology exploring the lived experiences of teachers in two rural Montana schools that have adopted the Summit Learning platform and maintained its use into the pandemic. Participants of this study taught core courses, such as math, science, and history. Results of this study indicate a high level of curriculum modification and support from leadership. Participants reported modified changes to the Summit Learning curriculum ranging from slight changes to significant changes based on individual participant’s perception of what students should and should not learn. Additionally, all participants reported the importance of leadership supporting curriculum changes and general classroom autonomy throughout the adoption and employment of Summit Learning. The results of this study inform the growing scholarship related to online learning platforms

    Tchen\u27s Sacred Isolation—Prelude to Malraux\u27s Fraternal Humanism

    While Malraux\u27s life-long quest was to seek new values in man\u27s perennial and shared struggle against an overwhelming fate, his early protagonist, particularly the assassin, turns to destruction and terrorism in a frenzied search for absolutes. This attempt to identify with the very fatality that has the power to destroy him is especially developed in Tchen, who embodies a despairing fascination with totalistic nihilism that Malraux must overcome in his search for a new notion of man. Tchen\u27s initiation to murder in La Condition humaine marks a transgression of a taboo that thrusts him into what Georges Bataille calls the realm of the sacred. His attempt to reconcile life and death by identifying with his victim irredeemably isolates Tchen from other, uninitiated men. Transformed by murder, he leaves the reality of revolution for the inhuman world of cosmic existence and individual death. Seeking to escape the human condition, he becomes obsessed with killing Chang-Kai-shek in order to kill himself and thereby possess his fate. But the illusion of such an escape dies with Tchen. Even his admiring disciples repudiate his nihilistic temptation as Malraux begins to seek in human fraternity the foundations of a new humanism

    This paper presents the Italian version of the Multilingual Assessment tool for Narratives (MAIN), describes how it was developed and reports on some recent uses of MAIN within the Italian context. The Italian MAIN has been used in different research projects and for clinical purposes; results have been presented at conferences and in peer reviewed papers. The results indicate that MAIN is an appropriate assessment tool for evaluating children’s narrative competence, in production and comprehension from preschool age (5 years) to school age (8 years) in typical language development, bilingual development and language delay/disorders

    Development of a Reference Wafer for On-Wafer Testing of Extreme Impedance Devices

    Get PDF
    This paper describes the design, fabrication, and testing of an on-wafer substrate that has been developed specifically for measuring extreme impedance devices using an on-wafer probe station. Such devices include carbon nano-tubes (CNTs) and structures based on graphene which possess impedances in the κ Ω range and are generally realised on the nano-scale rather than the micro-scale that is used for conventional on-wafer measurement. These impedances are far removed from the conventional 50- reference impedance of the test equipment. The on-wafer substrate includes methods for transforming from the micro-scale towards the nano-scale and reference standards to enable calibrations for extreme impedance devices. The paper includes typical results obtained from the designed wafer

    A V-shape superconducting artificial atom based on two inductively coupled transmons

    Full text link
    Circuit quantum electrodynamics systems are typically built from resonators and two-level artificial atoms, but the use of multi-level artificial atoms instead can enable promising applications in quantum technology. Here we present an implementation of a Josephson junction circuit dedicated to operate as a V-shape artificial atom. Based on a concept of two internal degrees of freedom, the device consists of two transmon qubits coupled by an inductance. The Josephson nonlinearity introduces a strong diagonal coupling between the two degrees of freedom that finds applications in quantum non-demolition readout schemes, and in the realization of microwave cross-Kerr media based on superconducting circuits.Comment: 5 pages, 3 figure

    Comparison between hybrid and fully kinetic models of asymmetric magnetic reconnection: coplanar and guide field configurations

    Full text link
    Magnetic reconnection occurring in collisionless environments is a multi-scale process involving both ion and electron kinetic processes. Because of their small mass, the electron scales are difficult to resolve in numerical and satellite data, it is therefore critical to know whether the overall evolution of the reconnection process is influenced by the kinetic nature of the electrons, or is unchanged when assuming a simpler, fluid, electron model. This paper investigate this issue in the general context of an asymmetric current sheet, where both the magnetic field amplitude and the density vary through the discontinuity. A comparison is made between fully kinetic and hybrid kinetic simulations of magnetic reconnection in coplanar and guide field systems. The models share the initial condition but differ in their electron modeling. It is found that the overall evolution of the system, including the reconnection rate, is very similar between both models. The best agreement is found in the guide field system, which confines particle better than the coplanar one, where the locality of the moments is violated by the electron bounce motion. It is also shown that, contrary to the common understanding, reconnection is much faster in the guide field system than in the coplanar one. Both models show this tendency, indicating that the phenomenon is driven by ion kinetic effects and not electron ones.Comment: 11 pages, 8 figures, accepted in Physics of Plasma

    Computation reduction for turbo decoding through window skipping

    Get PDF
    A simple and effective technique to skip the computation of reliable portions of a frame (windows) for turbo code decoding is proposed. The proposed criterion relies on a very simple approximation of cross-entropy measure by means of thresholding. This criterion features negligible complexity and low-memory requirements. Simulation results show that, in the best case, up to 20% of windows can be skipped with no error-rate degradation. Such a significant computation reduction can be exploited to directly reduce the power consumption as well
