Urban area change detection procedures with remote sensing data

The underlying factors affecting the detection and identification of nonurban to urban land cover change using satellite data were studied. Computer programs were developed to create a digital scene and to simulate the effect of the sensor point spread function (PSF) on the transfer of modulation from the scene to an image of the scene. The theory behind the development of a digital filter representing the PSF is given as well as an example of its application. Atmospheric effects on modulation transfer are also discussed.

The Use Of A Service-Learning Model And Online Dialogue To Promote Reflection, Critical Thinking, And Cultural Competence In Early Childhood Studies Students

Service learning has grown in popularity as an effective model to enhance critical reflection. A characteristic of effective service learning is the linking of "hands on" experience in the community with academic curriculum.  A service learning initiative between a 4-year college early childhood teacher preparation program and an Early Head Start (birth – age 3) program located on an American Indian reservation is effectively combined with asynchronous online dialogue. The results suggest an increase in self-awareness and cultural competence. This paper explores service learning, the use of online dialogue to promote self-awareness and reflection, and the convergence of these two teaching strategies to enhance cultural competence in a multicultural world

Professional Quality of Life: An Examination of Compassion Fatigue and Compassion Satisfaction in Athletic Trainers

Abstract Context: Compassion Fatigue is prevalent in many health care professions; however, prevalence in athletic trainers have not been examined. Given the high rate burnout and excessive demand placed upon those employed in athletic training profession, there is a need to examine the overall professional quality of life in order to identify compassion imbalances that may affect both patient care and personal well-being. Methods: A total of 293 clinically active National Athletic Trainers’ Association (NATA) members (33.4% male, 66.6% female) completed a demographics questionnaire along with the Professional Quality of Life-21 (ProQOL-21) survey provided via Qualtrics online software. Descriptive statistics were used to determine the prevalence of the professional quality of life scales including compassion satisfaction and compassion fatigue, and a Pearson’s Correlation was conducted to examine the relationship between these two factors. Results: More than half the participants (55.3%, n = 162) experienced an average level of compassion fatigue, while another 25.6% (n = 81) of participants were categorized as experiencing high compassion fatigue. Similarly, half of the participants (53.6%, n = 157) experienced average compassion satisfaction. The bivariate correlation analysis indicated a significant, negative relationship between compassion fatigue and satisfaction, r = -.377, n = 293, p = .001. Conclusions: Athletic Trainers experience average satisfaction in their clinical compassion when providing care to patients; however, compassion fatigue is also prevalent in this profession. Additional research is warranted to further investigate this relationship in athletic training and examine both prevention and causes of compassion fatigue. Word Count:25

The inefficiency of re-weighted sampling and the curse of system size in high order path integration

Computing averages over a target probability density by statistical re-weighting of a set of samples with a different distribution is a strategy which is commonly adopted in fields as diverse as atomistic simulation and finance. Here we present a very general analysis of the accuracy and efficiency of this approach, highlighting some of its weaknesses. We then give an example of how our results can be used, specifically to assess the feasibility of high-order path integral methods. We demonstrate that the most promising of these techniques -- which is based on re-weighted sampling -- is bound to fail as the size of the system is increased, because of the exponential growth of the statistical uncertainty in the re-weighted average

Sensitivity of an image plate system in the XUV (60 eV < E < 900 eV)

Phosphor imaging plates (IPs) have been calibrated and proven useful for quantitative x-ray imaging in the 1 to over 1000 keV energy range. In this paper we report on calibration measurements made at XUV energies in the 60 to 900 eV energy range using beamline 6.3.2 at the Advanced Light Source at Lawrence Berkeley National Laboratory. We measured a sensitivity of ~25 plus or minus 15 counts/pJ over the stated energy range which is compatible with the sensitivity of Si photodiodes that are used for time-resolved measurements. Our measurements at 900 eV are consistent with the measurements made by Meadowcroft et al. at ~1 keV.Comment: 7 pages, 2 figure

A probabilistic approach to some results by Nieto and Truax

In this paper, we reconsider some results by Nieto and Truax about generating functions for arbitrary order coherent and squeezed states. These results were obtained using the exponential of the Laplacian operator; more elaborated operational identities were used by Dattoli et al. \cite{Dattoli} to extend these results. In this note, we show that the operational approach can be replaced by a purely probabilistic approach, in the sense that the exponential of derivatives operators can be identified with equivalent expectation operators. This approach brings new insight about the kinks between operational and probabilistic calculus.Comment: 2nd versio

Error analysis of a finite difference method on graded meshes for a time-fractional diffusion equation

A reaction-diffusion problem with a Caputo time derivative of order = 2 (0; 1) is considered. The solution of such a problem is shown in general to have a weak singularity near the initial time t = 0, and sharp point wise bounds on certain derivatives of this solution are derived. A new analysis of a standard finite difference method for the problem is given, taking into account this initial singularity. This analysis encompasses both uniform meshes and meshes that are graded in time, and includes new stability and consistency bounds. The final convergence result shows clearly how the regularity of the solution and the grading of the mesh affect the order of convergence of the difference scheme, so one can choose an optimal mesh grading. Numerical results are presented that confirm the sharpness of the error analysis
