Impact of Conscious Discipline on Teacher Efficacy and Burnout: Perspectives for Elementary Teachers

Abstract: This study examined the impact of Conscious Discipline® on Michigan elementary teachers’ perceptions of their self-efficacy and burnout levels. Teachers completed a survey of the Teacher Sense of Efficacy Scale (TSES) and Maslach’s Burnout Inventory (MBI) and were observed using a fidelity instrument (Rain, 2014) by the researcher five months after the adoption of Conscious Discipline® school-wide in the treatment group (n = 12). The control group (n = 15) was matched with similar student population demographics, and the same surveys and fidelity instrument (Rain, 2014) were used. Results from this study found no statistical significance in the TSES or MBI scores between those in treatment and control groups. Additionally, no statistical significance was found in the observed implementation level of Conscious Discipline® and efficacy or burnout scores.

Ballistic transport in nanowires and carbon nanotubes

Abstract: The charge carriers in nanowires (NWs), carbon nanotubes (CNTs), and those confined to a very high magnetic field have one-dimensional (1D) character as quasi-free propagation of electron waves with analog energy spectrum exists only in one direction. The energy spectrum is quantum (or digital) in other two cartesian directions where electron waves are standing waves. In the quantum limit, an electron (hole) occupies the lowest (highest) digitized/quantized state giving it a distinct 1D character. The energy E =v F | k | in carbon-based devices is linearly dependent on the wave vector k, where v F ≈ 106 m/s. This is in direct contrast to parabolic character E =ħ2 k2/2m∗ in solids with effective mass m∗, for example in silicon NWs. The probability of changing wavevector from +ve to −ve direction through scattering or vice versa is greatly reduced and hence high mobility is expected, especially at low temperatures. The crucial outcome of this paper is the answer to the question: Does a higher mobility leads to a higher ultimate saturation velocity? The distribution function in a high electric field e is then naturally asymmetrical affected by the energy ±qel absorbed or emitted by a carrier of charge q during its ballistic flight in a mean free path l. The ultimate drift in response to a high electric field results in unidirectional streaming of the otherwise randomly-oriented velocity vectors in equilibrium. The high-field drift limited by the intrinsic velocity is ballistic, unaffected by scattering-limited processes. The ultimate velocity is further limited to an emission of a quantum either in the form of an optical phonon or a photon by an electron excited to a higher state by the applied electric field. The velocity does not depend on scattering parameters. Ballistic processes as a result of reduction in length of a CNT or NW below the scattering-limited mean free path l in the quasi-free direction are also discussed.

Performance evaluation of certain ARMA models in power spectral density estimation

Abstract: For an autoregressive moving average (p, q) process the performance measures considered are the asymptotic variance of the spectral estimator and the resolution of two closely spaced sinusoids in white noise. Though the AR parameters are mainly responsible for good resolution, it is shown that proper MA parameters are also necessary in some methods. Cadzow's (Indirect) method and the singular value decomposition (SVD) method are considered for comparison. It is found that both methods have approximately the same variance of the PSD estimates in the neighborhood of the frequencies of interest. The SVD method yields a much lower model order than Cadzow's method in which the MA parameters have greater influence on resolution. >
