Inspection Digital Literacy for School Improvement
Educational inspection, as an essential part of the current educational environment, supports
its mission through more pragmatic and comprehensive processes, techniques, and models,
which guarantee the right of students to quality education. The aim of the present study was to
determine the causal effect of gender and age on the dimensions of the instrument in the inspector
population. Specifically, 118 male and female inspectors from the Educational Inspection Service of
Andalusia (Spain) participated, with an average age of 47.56 years ( 5.70). In terms of gender, 30 were
women (25.40%) and 88 were men (74.60%). An instrument was developed specifically for this study
with the purpose of assessing the participants’ opinions of the extent to which their work contributes
to educational improvement. The results evidenced the relationship between the dimensions of the
instrument: attention to members of the educational community (AMEC), supervision of guidance
and tutorial action (SGTA), attention and inclusion of diversity (AID), and technological resources
(TR) (p < 0.01). Similarly, the multigroup model obtained good structural validity ( 2 = 68.180;
RMSEA = 0.078; GFI = 0.923; CFI = 0.959; IFI = 0.967). In terms of gender, no significant differences
were obtained, although the results were moderately superior among males compared to females.
In relation to age, younger inspectors had better TR results, and older inspectors had better AMEC
and SGTA results. The conclusions strengthen the importance of the Education Inspection Service
in educational establishments, highlighting the need to supervise the processes of attention and
inclusion for diversity. A great deal of resistance was observed, especially as there is a lack of training
in information and communication technology (ICT).Junta de Andalucía, research group No. HUM-8
Wound healing following refractive surgery in hens
Producción CientíficaThe wound-healing response is critical to the outcome of refractive surgery and studying wound healing contributes to an understanding of the
pathophysiology of other corneal injuries. Animal models allow research to be conducted with sufficient samples and under controlled parameters.
We studied the hen to determine the healing process from clinical, biophysical, and biological standpoints after photorefractive keratectomy
(PRK). PRK ( 6.0 diopters) was performed in hen eyes. At 3, 6, 12, 24, 48, and 72 h and 5, 7, 15, 30, and 60 days postoperatively, we
studied the clinical follow-up, objective measurements of light transmission (direct transmittance), apoptosis by TUNEL assay, proliferation by
immunocytochemical analysis of 5-bromo-20-deoxyuridine, and expression of alpha smooth muscle actin (SMA) in myofibroblasts in the
corneas. Hen corneas reepithelialize quickly. Haze developed from 5 to 60 days after surgery and was correlated with the appearance and
finalization of the expression of SMA. The direct transmittance of light was low during the first 15 days and improved at 30 and 60 days.
TUNEL-positive cells were observed 3 h after surgery and the numbers decreased thereafter. Epithelial proliferation began at 12 h and was
greater at 48 h, while stromal cell proliferation began at 24 h and was greater at 72 h. The hen cornea is anatomically similar to the human
cornea, and the manner in which it heals is a good model for studying different surgical techniques and pharmacologic assays
La adopción de tecnología en los invernaderos hortícolas mediterráneos
En la horticultura intensiva española la mayor parte de las exportaciones procede de los cultivos de invernadero, localizados en Almería, Murcia y Alicante, donde se ha centrado el presente estudio. Actualmente la posición competitiva no presenta amenazas muy graves pero tampoco muestra una etapa creciente. Exportaciones y precios soportan la competencia de otros países del área mediterránea, con los cuales España debe competir en capital y en tecnología elevando el nivel de equipamiento de los invernaderos. Ante unas exigencias de reestructuración de las instalaciones actuales, no aplazables, se plantea la presente tesis con el fin de conocer el estado actual de la tecnología y su evolución y, además, las características de las explotaciones y la actitud de sus titulares respecto a las innovaciones necesarias.
Las fuentes de información se han basado en una toma de precios en origen del tomate y pimiento, como principales productos hortícolas, y en una encuesta, realizada en 242 explotaciones, mediante muestreo proporcional estratificado, en las zonas de El Ejido (Almería), Valle del Guadalentín y Campo de Cartagena (Murcia) y Sur de Alicante.
El análisis de la información tuvo una primera parte dedicada a los precios, con el cálculo de la tendencia y la estacionalidad y la aplicación de modelos ARIMA. La finalidad ha sido conocer la evolución de las rentas de los productores, efectuar predicciones, y establecer una relación entre los precios y la tecnología adoptable.
El tratamiento de los datos de la encuesta con sus resultados comprende la mayor parte del contenido del trabajo. Se aplicó el análisis estadístico univariante a las características estructurales de explotaciones e invernaderos y el bivariante, con contraste de independencia, para determinar relaciones de interés entre los factores que influyen en los procesos de innovación.García Martínez, MDC.

The relationship between knowledge management and innovation level in Mexican SMEs: Empirical evidence
The transformation of the current society from an industry-based economy to a knowledge management and innovation-based economy is changing the design and implementation of business strategies and the nature of the competition among the organizations which are mainly small and medium-size enterprises (SMEs). They struggle to survive in a market which is more demanding and competitive, so they seeknowledge management as one of the most effective strategies that may help to enable the innovation activities into the businesses. For these reasons, this research paper has as a main goal to analyze the relationship between knowledge management and innovation in Mexican SMEs. The empirical analysis used 125 manufacturing SMEs (each SME having from 20 to 250 employees) as a sample to be carried out. The obtained results indicate that knowledge management has a positive impact in products, process, and management systems innovation
Innovation in journalism educational programmes at university. A systematic review of educational experiences at Spanish universities
The journalism being taught at universities in Spain is undergoing intensive changes as a result of the dual pressure exerted by the impact of digitisation in two specific aspects. The first is the journalistic system itself (business models, professional routines, information consumption, etc.). The second aspect involves the teaching guidelines established as a result of the implementation of the European Higher Education Area (EHEA). Focusing on the latter issue, the current debate regarding the orientation of journalistic education is calling for this aspect not to be relegated or limited to training in technical skills, which are constantly being renewed by technological developments of the digital environment. On the contrary, journalism education must also take into account other skills that foster the achievement of critical thinking, which is fundamental for the exercise of the journalistic profession. However, in the face of an increasingly digitised, competitive labour market, journalism studies and their training programmes also have a duty to provide the skills and competencies demanded by this market. In this paper, we have conducted a systematic review of some of the experiences of innovative teaching that have been successfully carried out in Journalism degrees taught in Spain for this purpose (service-learning, project-based learning, content curation, and edublogs, among others). These experiences reflect the involvement of university professors in providing comprehensive education for future journalists, with a strong emphasis on the intensive use of the digital resources currently available. 
The application of spatial analysis to cadastral zoning of urban areas: an example in the city of Madrid.
Spatial Analysis has been used since the 1990s for hedonic cadastral models of urban areas in large cities. This research aims to apply spatial analysis to zoning a district in Madrid located in the central part of the city in order to estimate urban housing prices. In doing so, the necessary data have been gathered ? both vector and raster- as found on the official government website and private company websites. This was done firstly to analyse the characteristics and then for the objectives of the study because it is rather helpful to use these types of analyses based on vector and raster data along with interpolation methods that obtain regular structures and attempt to avoid the subjective component inherent to traditional procedures. The essence of the work consisted of studying the minimum parameters that influence housing appraisals to resolve the problem. Normally, cadastral appraisal work fulfils the Official Technical Regulations in each country considering a greater number of parameters and corrective coefficients. The importance of this work consisted of lowering and prioritising the number of basic parameters necessary to set urban housing prices. The conclusions section confirms a high likelihood of successfully reducing the number of parameters to achieve an appraisal value that is similar to the one obtained using official methods
Computational prediction of the spectroscopic parameters of methanediol, an elusive molecule for interstellar detection
Producción CientíficaThe molecular structure of methanediol has been investigated by means of quantum chemical calculations. Two conformers, corresponding to C2 and Cs symmetries, respectively, were considered. The C2 conformer is found to lie about 1.7 (at 298 K) or 2.3 (at 0 K) kcal mol−1 below the Cs conformer. Predictions for their rotational constants, vibrational frequencies, IR intensities, and dipole moments have been provided. The lowest-lying isomer has a very low dipole moment, around 0.03 D, whereas the Cs conformer has a relatively high dipole moment, namely, 2.7 D. The barrier for the Cs→C2 process is predicted to be around 0.7–1 kcal mol−1. Based on the energetic results the proportion of the Cs conformer is likely to be negligible under low temperature conditions, such as in the interstellar medium. Therefore, it is predicted that detection by radioastronomy of methanediol would be rather unlikely.Junta de Castilla y León (programa de apoyo a proyectos de investigación – Ref. VA330U13
