TL;DR: An overall pattern of results highlights the importance of exploring new media environments, such as the current drive toward media multitasking, and reinforces that self-monitoring, post hoc surveying, and lay theory may offer only limited insight into how individuals interact with media.
Abstract: Changes in the media landscape have made simultaneous usage of the computer and television increasingly commonplace, but little research has explored how individuals navigate this media multitasking environment. Prior work suggests that self-insight may be limited in media consumption and multitasking environments, reinforcing a rising need for direct observational research. A laboratory experiment recorded both younger and older individuals as they used a computer and television concurrently, multitasking across television and Internet content. Results show that individuals are attending primarily to the computer during media multitasking. Although gazes last longer on the computer when compared to the television, the overall distribution of gazes is strongly skewed toward very short gazes only a few seconds in duration. People switched between media at an extreme rate, averaging more than 4 switches per min and 120 switches over the 27.5-minute study exposure. Participants had little insight in...

TL;DR: In this paper, the authors derived quasi-linear velocity-space diffusion coefficients due to L-mode electromagnetic ion cyclotron (EMIC) waves in a multispecies plasma and applied them to radiation belt electrons at L = 4, for EMIC waves in the hydrogen, helium and oxygen bands representative of different phases of a magnetic storm.
Abstract: [1] Quasi-linear velocity-space diffusion coefficients due to L-mode electromagnetic ion cyclotron (EMIC) waves are considered in a multispecies plasma. It is shown, with slight approximations to exact cold plasma theory, that within EMIC pass bands the index of refraction is a monotonically increasing function of frequency. Analytical criteria are then derived which identify ranges of latitude, wavenormal angle, and resonance number consistent with resonance in a prescribed wave population. This leads to computational techniques which allow very efficient calculation of the diffusion coefficients, along the lines previously developed for whistler and ion cyclotron waves in an electron-proton plasma. The techniques are applied to radiation belt electrons at L = 4, for EMIC waves in the hydrogen, helium, and oxygen bands representative of different phases of a magnetic storm. Finally, diffusion coefficients for recovery-phase helium-band EMIC waves are combined with those for typical whistler hiss, resulting in electron precipitation lifetimes substantially less than those due to hiss alone.

TL;DR: In this article, a nonparametric test for parametric conditional distributions of dynamic models is proposed, coupled with Khmaladze's martingale transformation, which is asymptotically distribution-free and has nontrivial power against root-n local alternatives.
Abstract: This paper proposes a nonparametric test for parametric conditional distributions of dynamic models. The test is of the Kolmogorov type coupled with Khmaladze's martingale transformation. It is asymptotically distribution-free and has nontrivial power against root-n local alternatives. The method is applicable for various dynamic models, including autoregressive and moving average models, generalized autoregressive conditional heteroskedasticity (GARCH), integrated GARCH, and general nonlinear time series regressions. The method is also applicable for cross-sectional models. Finally, we apply the procedure to testing conditional normality and the conditional t-distribution in a GARCH model for the NYSE equal-weighted returns.

TL;DR: An integrative framework of major responses to highly intense ambivalence avoidance, domination, compromise, and holism that is applicable to actors at the individual and collective levels is offered.
Abstract: The experience of simultaneously positive and negative orientations toward a person, goal, task, idea, and such appears to be quite common in organizations, but it is poorly understood. We develop a multilevel perspective on ambivalence in organizations that demonstrates how this phenomenon is integral to certain cognitive and emotional processes and important outcomes. Specifically, we discuss the organizational triggers of ambivalence and the cognitive and emotional mechanisms through which ambivalence diffuses between the individual and collective levels of analysis. We offer an integrative framework of major responses to highly intense ambivalence avoidance, domination, compromise, and holism that is applicable to actors at the individual and collective levels. The positive and negative outcomes associated with each response, and the conditions under which each is most effective, are explored. Although ambivalence is uncomfortable for actors, it has the potential to foster growth in the actor as well as highly adaptive and effective behavior.
