Editor for creating and applying computerise surveys

The parallel development of the psychometric assessments and the computer technologies determined a big revolution regarding the construction and the application of psychological and educational tests. This report describes a computerized system that allows researchers to creating, applying, and tabulating surveys and paper instruments in an automatized way. Many studies describe the use of this tool, highlighting its main characteristics. This system can be considered a useful tool, since it permits to input data with higher precision and no need for previous codifications. Further, it allows researchers to know the latency period from the answer to each and every item. The prospects about new versions of the system stress on: extending the number of measured topics; creating automatic corrections systems; managing data via internet; and selecting the most valid items to measure each matter or specific groups of persons

Effects of computerized visual feedback on the adjustment of time in planning physical education

The planning in Physical Education (PE) is a crucial competency of Pre-service Teachers (PTs) that is developing throughout the university courses. The adjustment of the time planned is a common problem for PTs without experience, and they show high differences between the time that they program and the real time that they employ during the intervention phase of teaching PE. We created a computerized time sheet to deliver visual feedback to PTs about this difference. Our aim was to accommodate quickly the adjustment of the time in planning in PE in a few sessions of visual feedback and coaching meeting with the supervisor of the faculty. We expose the computerized sheet and its application on one PT (an individual case) with a repeated measures series (three trials of baseline and ten trials of intervention were carried out). The results show us the efficacy of the computerized sheet (visual feedback and coaching meeting). We could verify the inflection of the curve since the first treatment trials, decreasing the differences between the time planned and the real time employed during the classes. We conclude that this method is a good way for PTs training during their university courses and for in-service teachers who want to improve their accuracy of planning PE in the future

El adulto mayor chihuahuense presenta condiciones de salud muy heterogéneas, que incluyen la presencia de enfermedades crónicas (hipertensión, diabetes, artritis), así como algunos factores de riesgo de las mismas, como sobrepeso, obesidad y obesidad troncal. Adicionalmente existen aspectos sociales que condicionan su detección y atención como la baja escolaridad, el estado civil y el acceso a servicios de salud. También presentan incapacidad física, cognitiva y cifras preocupantes de depresión que pueden afectar su estado de salud general o favorecer la aparición de otras enfermedades

Universidad sustentable

En este proyecto se dio continuidad a Guía práctica para instituciones sustentables y se atendió la problemática de la desvinculación de proyectos y el desaprovechamiento de residuos y espacios dentro del campus. Como solución, se inició la creación de un catálogo de vinculación de proyectos, se diseñó mobiliario con poco impacto ecológico para las nuevas áreas del TID y se siguió con el desarrollo del proyecto de reciclaje de PET en el ITESO

Temperature and dissolved oxygen concentration in the Pacific Ocean at the northern region of the oxygen minimum zone off Mexico between the last two PDO cool phases

8 pages, 5 figures, 1 tableThe changes in temperature and dissolved oxygen concentration in the Pacific Ocean in the northern region of the shallow oxygen minimum zone (OMZ) off Mexico were analyzed on the basis of the Word Ocean Database and a series of oceanographic cruises (LEGOZ-Mex). In order to test the changes in both parameters between two similar oceanographic scenarios according to the Pacific Decadal Oscillation (PDO), a comparison was made between the last two cool PDO phases of 1962–1974 and 2002–2012 when conditions might be expected to be relatively similar. Results show that the surface layer (upper layer of 50 m depth) has been warming significantly in two of the three areas included in this study: 1) the southern end of the California Current (0.8 °C; p < 0.001), 2) the southern Gulf of California (0.49 °C; p < 0.001), and 3) the Tropical Transitional Pacific (0.4 °C). Simultaneously, the water column has been deoxygenating significantly (p < 0.001), not only in the subsurface shallow OMZ layer (~ 100 to 300 m depth) in the Tropical Transitional area (− 45%), as has been recorded previously, but from 300 to 1000 m depth (by between −38% and - 57%). The exception was the California Current area at the northern limit of the shallow OMZ, where the deoxygenation was only significant (p < 0.001) from 300 to 1000 m depth (~ − 20%). We conclude that the significant warming of the surface layer in the Pacific OMZ off Mexico has increased the stratification of the water column and contributed to the deoxygenation of the interior ocean, at least between the last two cool phases of the PDO. These changes may be significantly affecting the marine biota that inhabit the shallow OMZsThis work was made possible thanks to the financial support of SEP-CONACyT (contract 2014-236864, L S.V.), Fronteras de la Ciencia-CONACyT (contract 2015-2-280, L.
