    Abstract In a society where it is becoming more common for perpetrators to choose electronic forms of communication (cell phones, social media, etc.) to bully others, it is crucial that we understand how our country is working to intervene in this cyberbullying epidemic. Therefore, this systematic research synthesis sought to examine all intervention efforts addressing cyberbullying that have been implemented within the United States. A systematic search using variations of cyberbullying intervention program search terms was narrowed down to a final sample size of 11 articles fitting the inclusion and exclusion criteria. Results suggested that programs addressing cyberbullying have only been implemented in schools or online, and most have not been evaluated for their effect on actual cyberbullying behaviors, but rather on attitudes and intentions about cyberbullying. Despite the significant concern about cyberbullying and its potential problematic outcomes, there seems to be a glaring lack of effective evidence-based programs that have been implemented in the United States.

  2. Article ; Online: Voltammetric Measurement of Rates and Energetics for Surface Methoxylation of Si(100) in Methanol with Dissolved Electron Acceptors Using Si Ultramicroelectrodes.

    Abstract The steady-state voltammetric responses of n-type Si(100) semiconductor ultramicroelectrodes (SUMEs) immersed in air- and water-free methanolic electrolytes have been measured. The response characteristics of these SUMEs in the absence of illumination were modeled and understood through a framework that describes the distribution of the applied potential across the semiconductor/electrolyte contact using four discrete regions: the semiconductor space charge, surface, Helmholtz, and diffuse layers. The latter region was described by the full Gouy-Chapman model. This framework afforded insight on how relevant parameters such as the semiconductor band edge potentials, the reorganization energies for charge transfer, the standard potential of redox species in solution, the density and energy of surface state populations, and the presence of an insulating (tunneling) layer individually and collectively dictate the observable current-potential responses. With this information, the methoxylation of Si surfaces was evaluated by analysis of the change in voltammetric responses during the course of prolonged immersion in methanol. The electrochemical data were consistent with a surface methoxylation mechanism that depended on the standard potential of redox species dissolved in solution. Estimates of the enthalpies of adsorption as well as the potential-dependent rate constant for surface methoxylation were obtained. Collectively, these measurements supported the contention that the rates of Si surface reactions can be systematically tuned by exposure to dissolved outer-sphere electron acceptors. Moreover, the data represent the quantitative utility of voltammetry with SUMEs for the measurement of semiconductor/liquid contacts.

    Abstract The ventricular arrhythmia Torsades de Pointes (TdP) is a common form of drug-induced cardiotoxicity, but prediction of this arrhythmia remains an unresolved issue in drug development. Current assays to evaluate arrhythmia risk are limited by poor specificity and a lack of mechanistic insight. We addressed this important unresolved issue through a novel computational approach that combined simulations of drug effects on dynamics with statistical analysis and machine-learning. Drugs that blocked multiple ion channels were simulated in ventricular myocyte models, and metrics computed from the action potential and intracellular (Ca(2+) ) waveform were used to construct classifiers that distinguished between arrhythmogenic and nonarrhythmogenic drugs. We found that: (1) these classifiers provide superior risk prediction; (2) drug-induced changes to both the action potential and intracellular (Ca(2+) ) influence risk; and (3) cardiac ion channels not typically assessed may significantly affect risk. Our algorithm demonstrates the value of systematic simulations in predicting pharmacological toxicity.

    Abstract Introduction: Ventricular tachycardia (VT) normally occurs from an abnormal structural substrate.
    Case: We report a case in which VT was caused by a large tumor in the interventricular septum. Surgical intervention was not an option due to the location of the tumor and its proximity to the coronary arteries.
    Conclusion: The patient underwent ablation and upgrade to CRT before ultimately receiving a heart transplant.

    Abstract Semiconductor ultramicroelectrodes (SUMEs) were prepared by photolithographic patterning of defined pinholes in dielectric coatings on semiconductor wafers. Methods are reported for interpreting their electrochemical response characteristics in the absence of illumination. Radial diffusion is reconciled with the diode equation to describe the full voltammetric response, allowing direct determination of heterogeneous charge-transfer rate constants and surface quality. The voltammetric responses of n-type Si SUMEs were assessed and showed prototypical UME characteristics with obtainable current densities higher than those of conventional macroscopic electrodes. The SUME voltammetry proved highly sensitive to both native and intentionally grown oxides, highlighting their ability to precisely track dynamic surface conditions reliably through electrochemical measurement. Subsequently, electron transfer from the conduction band of n-Si SUMEs to aqueous Ru(NH
