The Relationship between Organizational Health and Student Achievement in High Poverty Schools

The purpose of this study was to examine the relationship between organizational health and student achievement of economically disadvantaged students in a large school district along the Texas-Mexico border that serves 99 % Hispanic students; districtwide approximately 95 % of the students are economically disadvantaged. All schools in the district are Title I schools and enroll 78%- 100% economically disadvantaged students. About forty-eight percent (48.3 %) of students served are English Language Learners. Student achievement was determined using the State of Texas Assessment of Academic Readiness (STAAR) and organizational health was determined using an Organizational Health Inventory that measures the ten dimensions of organization-al health posited by Matthew Miles and operationalized by Marvin Fairman and Associates. The strength of the relationship was determined by using the Pearson correlation coefficient. The findings indicate that there is a positive relationship between student achievement in high poverty Hispanic schools and organizational health. The strongest relationship exists with the dimensions of goal focus, problem solving adequacy, and cohesiveness. Student achievement increases as the dimension of goal focus increase

Efficient parallelization of quantum basis state shift

Basis state shift is central to many quantum algorithms, most notably the quantum walk. Efficient implementations are of major importance for achieving a quantum speedup for computational applications. We optimize the state shift algorithm by incorporating the shift in different directions in parallel. This provides a significant reduction in the depth of the quantum circuit in comparison to the currently known methods, giving a linear scaling in the number of gates versus working qubits in contrast to the quadratic scaling of the state-of-the-art method based on the quantum Fourier transform. For a one-dimensional array of size $2^n$ for $n > 4$, we derive the total number of $15n + 74$ two-qubit $CX$ gates in the parallel circuit, using a total of $2n-2$ qubits including an ancilla register for the decomposition of multi-controlled gates. We focus on the one-dimensional and periodic shift, but note that the method can be extended to more complex cases

Distributed multivariate regression with unknown noise covariance in the presence of outliers: an MDL approach

We consider the problem of estimating the coefficients in a multivariable linear model by means of a wireless sensor network which may be affected by anomalous measurements. The noise covariance matrices at the different sensors are assumed unknown. Treating outlying samples, and their support, as additional nuisance parameters, the Maximum Likelihood estimate is investigated, with the number of outliers being estimated according to the Minimum Description Length principle. A distributed implementation based on iterative consensus techniques is then proposed, and it is shown effective for managing outliers in the data.Peer ReviewedPostprint (author's final draft

In order to mitigate the errors induced by the nodes in NLOS, we derive an algorithm that combines the expectation-maximization algorithm with a weighted least-squares estimation of the source position so that the nodes in NLOS are eventually identified and discarded. Moreover, a distributed version of this algorithm based on a diffusion strategy that iteratively refines the position estimate while driving the network to a consensus is presented.Peer ReviewedPostprint (author's final draft

The Role of the School District in High-Performance Title One Schools in South Texas

A mixed research study was designed and conducted to identify effective characteristics of high-performing, high-poverty schools. Four South Texas Title 1 schools identified as High Performing Schools by the Texas Education Agency in 2016 were selected for the study. To be selected, these schools were also required to meet or exceed a set of criteria applied by the researchers. An effective school model, comprised of eleven characteristics and school processes, was developed based on a synthesis of effective school research and served as the theoretical framework for the study. The characteristics include Culture, Leadership, Instruction, Improvement, Home and Community Relations, Curriculum, Environment, Professional Development, Vision/Mission, Resources, and Staff. Data was collected from professional school staff, principals, and parents related to the essentiality of the eleven effective characteristics and processes used by the schools. Onsite data collection from each school included a staff survey, focus group session, principal interview, and a parent survey. Results supported the essentiality of the eleven school characteristics synthesized from previous effective schools’ studies. The results also yielded valuable school district strategies that supported the High-Performing Reward Title 1 schools. These strategies included the provision of active specialized support by district staff, district curriculum designed by district teachers during the summer, instructional resources selected through teacher input, flexibility in implementing district supports, professional development during summer and the school year to meet individual teacher needs, district-designed student assessment, an intradistrict and inter-district competitive school environment focused on student achievement, and parent initiatives aligned to local needs

Programa de prácticas de temas selectos en salud animal (2004)

Elaborar un programa integral de salud animal en una unidad de producción pecuaria seleccionada por el discente a partir de identificar por observación y por entrevista las problemáticas; y diagnosticadas, en el caso de las enfermedades hacer uso del laboratorio clínico y confirmar la presencia o ausencia de enfermedad; elaborar un programa sanitario, así como de bienestar animal, de reducción de impacto al medio ambiente y biodiversidad. Trabajar en la implementación de las propuestas y medir su impacto. Acceder a los bancos de información de los organismos nacionales e internacionales y campañas nacionales, para identificar los programas y las enfermedades. Identificación de la presencia o ausencia de enfermedad en la unidad de producción, bienestar animal, alimentación, manejo zootécnico, impacto ambiental y biodiversividad. La práctica se desarrollará en las unidades de producción animal, salón de clases y sala de cómputo para acceder a bases de datos
