Testing the Factorial Validity of the Classroom Engagement Inventory with Spanish Students

Introduction: The purpose of the study was to test the factorial validity of Classroom Engagement Inventory of Wang, Bergin and Bergin with Spanish high school students. Methods: In this study, 546 students participated (mean = 13.27, standard deviation = 0.629), from several high schools in Andalusia. To analyze the psychometric properties of the scale, several analyses were carried out. Results: The results offered support for the five-factor structure. The analysis of invariance with respect to gender showed that the factor structure of the questionnaire was invariant. The Cronbach alpha values were higher than 0.70 in the subscales. Discussion: The results of this study demonstrated the reliability and validity of the Spanish version of the Classroom Engagement Inventory with high school students

Patterns of Academic Scientific Collaboration at a Distance: Evidence from Southern European Countries

The main objective of this chapter is to examine the trends of academic scientific collaboration (SC) at a distance among public universities located in peripheral countries: Spain, Italy, Greece, and Portugal. The data to capture scientific collaboration consists of a set of co-authored articles published between 2001 and 2010 by universities located in the mentioned Southern countries, indexed by the Science Citation Index expanded (SCI Expanded) of the Information Sciences Institute (ISI) Web of Science (WoS) database. We link this data to institution-level information provided by the EUMIDA dataset. In addition, we retrieved regional data on economic variables from Eurostat. The methodology relies on a descriptive analysis of the evolution of co-publications at different notions of proximity. Our results show a trend toward collaboration over longer distances, although we find heterogeneity by countries and disciplines. Building on our results, we provide some policy implications

The diffusion of energy technologies. Evidence from renewable, fossil, and nuclear energy patents

Technology innovation is widely recognised as a critical means in tackling climate change and fulfilling energy policy objectives. The objective of this paper is twofold: first, to provide a descriptive analysis of innovation in energy technology across countries and sectors and over time; and second, to explore the determining factors of patented knowledge diffusion of energy technologies by distinguishing between renewables and other energy patents, i.e., fossil and nuclear patents) thorough a regression analysis. The data employed in this paper consists of an original database on renewables and other energy patents applied by firms in the period 1990–2015 and contained in PATSTAT. By drawing on patent citations as an indicator of knowledge diffusion and focusing on characteristics extracted from patent documents, a set of econometric models is estimated. Our results show that those patents containing more citations to previous scientific literature and patents attain greater diffusion. Joint patents with other firms or universities exert a negligible effect on technology regarding renewables. Coownership with universities has a negative effect on the diffusion of other types of energy technology. Several policy implications can be determined from our results: for example, the justification for policies oriented towards enhancing the incorporation of scientific knowledge and co-inventorship in energy innovation

Genomic Information Systems applied to Precision Medicine: Genomic Data Management for Alzheimer’s Disease Treatment

The Alzheimer’s Disease is one of the most prevalent neurological disorders in our current society. The study of the genetic characteristics of every patient, makes possible the study of significant DNA variations in order to ease an early diagnosis, essential to stop the progression of the disorder. The problem is that the vast amount of available information makes necessary the use of a method designed to adequately store and manage this data in an optimal way for its exploitation. In this context, the Information Systems Engineering in general and the conceptual modelling techniques in particular, provide a suitable solution in order to determine which data is relevant and how to manage the corresponding information. With these fundamentals in mind, this paper introduces a particular example to bear the methodological treatment of the search, filter and load of genomic variations related to Alzheimer’s Disease for its later exploitation with clinical purposes

Bioactive compounds content and total antioxidant activity of two savoy cabbages

Se han identificado, cuantificado y comparado los compuestos bioactivos, así como la actividad antioxidante in vitro, de dos cultivos de repollo, Dama y Leticia, cultivados en el oeste de España. Encontramos que el cv. Dama, presentado en general, mejora los resultados en comparación con el cv. Leticia. El cv. Dama presentó una mayor concentración de clorofila (2,26 mg / 100 g de peso en fresco), un contenido fenólico total (102,71 mg de equivalente de ácido clorogénico / 100 g en peso fresco) y unos glucosinolatos totales intactos (195,22 μmol de equivalente de sinigrina / 100 g de peso fresco). Así, el cv. Dama exhibió unos valores más altos de actividad antioxidante in vitro.The bioactive compounds, as well as the in vitro antioxidant activity of two Savoy cabbage cultivars, Dama and Leticia, grown in west of Spain under similar conditions were identified, quantified and compared. We found that cv. Dama presented in general betters results when compared with cv. Leticia. Cv. Dama presented higher concentrations of chlorophyll a (2.26 mg/100 g fresh weight), total phenolic content (102.71 mg of chlorogenic acid equivalent/100 g fresh weight) and total intact glucosinolates (195.22 μmol of sinigrin equivalent/100 g fresh weight). Thus, cv. Dama exhibited higher values of in vitro antioxidant activity.María Fernanda Fernández León agradece la ayuda prestada por el Instituto Nacional de Investigación y Tecnología Agraria (INIA) Trabajo parcialmente patrocinado por la Junta de Extremadura y Fondos FEDER.

PMMA stability under hydrothermal conditions

Producción CientíficaPMMA is a synthetic polymer of methyl methacrylate. PMMA is used widely in many applications and the interest in their physicochemical properties is growing. In this work, a hydrothermal study was carried out to evaluate the PMMA stability under hydrothermal conditions (up to 200˚C), pH (2 to 10) and reaction time (up to 360 min). The water-PMMA system is affected by different mechanisms when dosed with bases or acids suggesting predominantly an interaction of ester groups with the medium. The results prove that the polymer is highly stable at the tested conditions. It is observed that water molecules are encapsulated in the polymer due to the softening and hardening during the process. This phenomenon was seen in the thermogravimetric analysis. The glass transition temperature of PMMA was slightly reduced after the treatment. This suggests that the hydrothermal process promotes the degradation of the shortest polymeric chains.Agencia Estatal de Investigación (PID2020-119249RA-I00)Junta de Castilla y León - EU-FEDER (CLU-2019-04)Ministerio de Ciencia, Innovación y Universidades - grant “Beatriz Galindo” (BEAGAL18/00247
