The impact of school-based child centered play therapy on academic achievement, self-concept, and teacher-child relationship stress.

This study examined the effectiveness of child centered play therapy (CCPT) with academically at-risk 1st graders. In this quasi-experimental design, twenty-one 1st grade students were assigned to the experimental group and 20 students were assigned to the no treatment control group. The children in the experimental group received two 30 minute play therapy sessions per week for the duration of eight weeks. Three hypotheses were analyzed. A two-factor repeated measures analysis of variances (SPANOVA) were performed on each dependent variable to determine if the experimental group performed differently from the control group across time according to the pretest and posttest results of the Young Child's Achievement Test (YCAT), the Pictorial Scale of Perceived Competence and Social Acceptance for Young Children (PSPCSAYC), and the Student-Teacher Relationship Scale (STRS). Additionally, partial η2 was calculated to determine practical significance. One hypothesis was retained at the .05 level of significance. Findings indicated that academically at-risk 1st graders who participated in CCPT scored statistically significant higher on academic achievement. Specifically, children assigned to the experimental group demonstrated a statistically significant increase in Early Achievement Composite (p = .03) when compared to children assigned to the no treatment control group. No statistical significant results were found on Self-Concept and Student-Teacher Relationship Stress

They settled an important part of they fortune in the Kingdom of Granada and in the city of Malaga. This record also allows to know how the widow, Beatriz Galindo, could appealed the King and Queen because she was in disagreement with the last wish of Francisco Ramírez de Madrid

Unobserved heterogeneity, exit rates, and re-employment wages

Exit rates from unemployment and re-employment wages decline over an unemployment period after controlling for worker observable characteristics. We study the role of unobserved heterogeneity in an economy with asymmetric information and directed search. We show that the unique equilibrium is separating and skilled workers have more job opportunities and higher wages. The composition of the unemployed varies with the duration of unemployment, so average exit rates and wages fall with time. The separating equilibrium relies on performance-related pay schemes and the ability of firms to commit to renting an input that is complementary to the worker skills

Estudio de tumores de la cavidad nasal y senos paranasales del perro mediante tomografía computarizada

En 8 perros se estudiaron imágenes de tomografía computarizada (TC), analizando la extensión de tumores de cavidad nasal y/o senos paranasales. La técnica resultó especialmente útil en animales con descarga nasal crónica, protrusión del globo ocular, ceguera de origen central o signos de disfunción neurológica por afectación de porciones rostrales del encéfalo.

Non equilibrium inertial dynamics of colloidal systems

We consider the properties of a one dimensional fluid of brownian inertial hard-core particles, whose microscopic dynamics is partially damped by a heat-bath. Direct interactions among the particles are represented as binary, instantaneous elastic collisions. Collisions with the heath bath are accounted for by a Fokker-Planck collision operator, whereas direct collisions among the particles are treated by a well known method of kinetic theory, the Revised Enskog Theory. By means of a time multiple time-scale method we derive the evolution equation for the average density. Remarkably, for large values of the friction parameter and/or of the mass of the particles we obtain the same equation as the one derived within the dynamic density functional theory (DDF). In addition, at moderate values of the friction constant, the present method allows to study the inertial effects not accounted for by DDF method. Finally, a numerical test of these corrections is provided.Comment: 13 pages+ 3 Postscript figure

La formetría aplicada a las deformidades de la columna.

La forma de la espalda es un factor importante en la evaluación clínica de varias afecciones de la columna, en particular de la escoliosis. Se describe un método de análisis de la forma de la superficie de la espalda que fue ideado para conocer la mayoría de los parámetros necesarios para evaluar el progreso de la enfermedad en tanto afecte a la forma del cuerpo. La medición de la forma de la superficie de la espalda y de las marcas anatómicas manuales se analizan a través de un sistema de ordenador-monitor en el que se escanea el plano de luz incidente sobre la espalda y desde topografía moiré. Las marcas anatómicas se llevan a cabo para definir los planos de referencia desde los cuales se comparan sucesivos análisis. Este método se emplea para estimar los ángulos de las vértebras límites y los ángulos de Cobb. Las secciones laterales muestran la cifosis y lordosis. Para los resultados se han llevado a cabo correlaciones de la asimetría lateral de la forma de la superficie con el ángulo de Cobb medido mediante radiografía. Las mediciones se llevaron a cabo en tres grupos de pacientes (47 pacientes en total). El rango osciló entre r=0.66 a r=0.88, para una p<0.001. El análisis de los resultados podría reducir en un futuro los exámenes con rayos X en el evolutivo, por lo evidenciado cuantitativamente y con inocuidad total tanto en la asimetría lateral como en la deformidad en el plano transverso.Peer Reviewe

Three-dimensional volume rendering in computed tomography for evaluation of the temporomandibular joint in dogs

Based on computed tomography (CT) images, volume rendering was used to obtain a three-dimensional representation of data (3DVR). The aims of this study included: describing the bone anatomy of the temporomandibular joint (TMJ) of dogs; comparing the TMJs of each dog by skull type and age; comparing 3DVR images with three-standard-plane CTs; assessing soft tissues adjacent to the TMJ and assessing pathological cases. Multidetector computed tomography scans of bilateral TMJs of 410 dogs were observed. From a ventral view, slight displacements in the positions of the skulls were seen, whereas from a caudal view, differences in amplitude of the articular space were observed. Dolichocephalic and mesaticephalic dogs showed more similar TMJ features than brachycephalic dogs. The shape of the TMJ bones were irregular in dogs under 1 year old. The 3DVR images related to the three-standard-plane CT improved the overall comprehension of the changes in the articular space amplitude and condylar process morphology. The fovea pterygoidea, mandibular fossa and retroarticular process were perfectly shown. A better spatial situation of adjacent soft tissues was obtained. The 3DVR represents an ancillary method to the standard-plane CT that could help in the understanding of the anatomy and diagnoses of different pathologies of the TMJ in dogs

Load that maximizes power output in countermovement jump

Introduction: One of the main problems faced by strength and conditioning coaches is the issue of how to objectively quantify and monitor the actual training load undertaken by athletes in order to maximize performance. It is well known that performance of explosive sports activities is largely determined by mechanical power. Objective: This study analysed the height at which maximal power output is generated and the corresponding load with which is achieved in a group of male-trained track and field athletes in the test of countermovement jump (CMJ) with extra loads (CMJEL). Methods: Fifty national level male athletes in sprinting and jumping performed a CMJ test with increasing loads up to a height of 16 cm. The relative load that maximized the mechanical power output (Pmax) was determined using a force platform and lineal encoder synchronization and estimating the power by peak power, average power and flight time in CMJ. Results: The load at which the power output no longer existed was at a height of 19.9 ± 2.35, referring to a 99.1 ± 1% of the maximum power output. The load that maximizes power output in all cases has been the load with which an athlete jump a height of approximately 20 cm. Conclusion: These results highlight the importance of considering the height achieved in CMJ with extra load instead of power because maximum power is always attained with the same height. We advise for the preferential use of the height achieved in CMJEL test, since it seems to be a valid indicative of an individual's actual neuromuscular potential providing a valid information for coaches and trainers when assessing the performance status of our athletes and to quantify and monitor training loads, measuring only the height of the jump in the exercise of CMJEL.Actividad Física y Deport
