Using data from 143 individuals, this study examined how pre-training socialization and task complexity affected learning in an online environment. A controlled laboratory experiment, using a 3 (socialization) × 2 (complexity) between subjects design was conducted. Participants were assigned to either more or less complex training and received either face-to-face, online, or no socialization before beginning the training. Results indicated that those who received face-to-face socialization performed better than those who received either online socialization or no socialization. There was no learning difference between the online and no socialization condition. Those who received simpler training performed better than those who received more complex training. Socialization and complexity were not interactively related. Implications for research and practice are discussed. © Published by Elsevier Ltd. Source

The Heisenberg model provides a simple but powerful theoretical platform for modelling magnetic molecules. In this article, we demonstrate that - despite its simplicity - an isotropic Heisenberg model successfully provides a comprehensive description of the magnetic properties of the {Fe 8}-cubane and the {Cr12Cu2} magnetic molecules. However, in order to achieve this success, it is necessary to employ a variety of sophisticated experimental and theoretical techniques. These include the use of pulsed-field measurements to observe a high-field (41 T) ground-state level crossing in the {Fe8}-cubane system, and tunnel-diode oscillator measurements, which we use to observe excited-state level crossings in the {Cr12Cu2} ring. For these two systems, the theoretical modelling was carried out using matrix diagonalization and quantum Monte Carlo calculations, respectively. © The Royal Society of Chemistry 2010. Source

We discuss how computers can be used to solve the ordinary differential equations that provide a quantum mechanical description of magnetic resonance. By varying the parameters in these equations and visually exploring how these parameters affect the results, students can quickly gain insights into the nature of magnetic resonance that go beyond the standard presentation found in quantum mechanics textbooks. The results were generated using an IPython notebook, which we provide as an online supplement with interactive plots and animations. © 2015 American Association of Physics Teachers. Source

This research note examines political institutional changes in the aftermath of terrorist assassinations. Contemporary assassinations are more often a component of wider campaigns of political violence rather than a singular attack on a head of state. The Global Terrorism Database counts 16,831 terrorist assassinations from 1970–2014, indicating significant frequency of these events and includes a wide range of targets from law enforcement officials to foreign diplomats. Utilizing survival analysis, the span of time from a terrorist assassination event to a change in political institutions within states is measured between target types. Outcome differences between target types are identified. © 2016 Taylor & Francis Group, LLC Source
