A theoretical investigation of the diradical character and cyclophane formation in π-conjugated diradicals.

π-Conjugated diradical compounds which feature unpaired electrons in the ground state are essential for understanding the nature of chemical bonds and have potential applications in material science1. In fact, an important research effort by our group has been directed towards carbazole-based diradicaloids2, aiming to explore how external stimuli impacts on supramolecular organization, and thus on the resulting optical and electronic properties. Thanks to this research, we have demonstrated that these materials are potential building blocks for dynamic covalent chemistry (DCC)3. In our present work, we wanted to explore beyond carbazole-based diradicals and analyse what would be the diradical character after modification of the chemical structure of the carbazole skeleton. For this purpose, we will analyse the structural and electronic properties of carbazole-based diradicals after the following chemical modifications: (i) heteroatom substitution, (ii) core elongation and (iii) insertion of donor/acceptor groups. In addition, the effect of the heteroatom substitution on the dynamic interconversion between the monomer and cyclophane aggregates will be also investigated.Universidad de Málaga.

Analysis of Psychometric Properties of the Quality and Satisfaction Questionnaire Focused on Sustainability in Higher Education

The aim of this research was to develop and validate a questionnaire to assess the quality of education, from a sustainability perspective, in higher education institutions of Naples (Italy), and determine whether differences exist between the groups (families, teachers and, students) with respect to their level of satisfaction concerning that quality, since it is important that education policies promote that assessment from an economic, social, environmental, and organisational dimension. The questionnaire was validated using a quantitative, quasi experimental, cross sectional method. A multivariate analysis of variance (MANOVA) was conducted on a sample of n = 1091 subjects to study the differences between the groups and their level of satisfaction. The results show a good reliability and validity. In this MANOVA, significant differences and large effect sizes were found. Families and teachers consider that quality management in higher education is adequate. The three groups are very satisfied with teaching management, and the teachers’ group has the higher level of satisfaction with teaching planning. It is concluded that this validated questionnaire provides information on the opinions about the quality of education from a sustainability perspective and that the self-assessment of those responsible for teaching is essential to achieve continuous improvementHUM-98

Recursos internos y externos para población reclusa y exreclusa del Centro Penitenciario de Zuera en la provincia de Zaragoza: Análisis de situación y propuesta de intervención.

Los niveles de reincidencia son un hecho social y mi interés desde el grado en trabajo social para elaborar este trabajo es por un lado, conocer y valorar las actividades y programas que este Centro adopta en este proceso y por otro lado indagar sobre las entidades sociales que atienden a población exreclusa con el fin de conocer los servicios a los que pueden acceder la población exreclusa en la provincia de Zaragoza ya que como muchos autores señalan, la responsabilidad de este proceso no sólo es individual, sino también social. Siguiendo la metodología de intervención propia del Trabajo Social, se considera importante respecto al objeto de estudio de este trabajo proponer un sistema de modelo en Red sobre las entidades sociales actuales de la provincia de Zaragoza que atienden a población exreclusa. El objetivo principal de este modelo es sistematizar los programas y proyectos que ofrecen estas entidades sociales ya que todas atienden las mismas necesidades y problemas que presenta este colectivo. Aplicando un mismo programa que incluya todos los servicios que ofrecen las entidades sociales dirigidos a esta población se llegaría a construir un espacio común, abierto y diversificado más flexible y menos burocrático en el que la atención ofrecida sería una práctica más eficaz

Supercritical Fluid Extraction of Fucoxanthin from the Diatom Phaeodactylum tricornutum and Biogas Production through Anaerobic Digestion

Phaeodactylum tricornutum is the marine diatom best known for high-value compounds that are useful in aquaculture and food area. In this study, fucoxanthin was first extracted from the diatom using supercritical fluid extraction (SFE) and then using the extracted diatom-like substrate to produce bioenergy through anaerobic digestion (AD) processes. Factors such as temperature (30 °C and 50 °C), pressure (20, 30, and 40 MPa), and ethanol (co-solvent concentration from 10% to 50% v/v) were optimized for improving the yield, purity, and recovery of fucoxanthin extracted using SFE. The highest yield (24.41% w/w) was obtained at 30 MPa, 30 °C, and 30% ethanol but the highest fucoxanthin purity and recovery (85.03mg/g extract and 66.60% w/w, respectively) were obtained at 30 MPa, 30 °C, and 40%ethanol. Furthermore, ethanol as a factor had the most significant effect on the overall process of SFE. Subsequently, P.tricornutum biomass and SFE-extracted diatom were used as substrates for biogas production through AD. The effect of fucoxanthin was studied on the yield of AD, which resulted in 77.15 ± 3.85 LSTP CH4/kg volatile solids (VS) and 56.66 ± 1.90 LSTP CH4/kg VS for the whole diatom and the extracted P.tricornutum, respectively. Therefore, P.tricornutuman can be considered a potential source of fucoxanthin and methane and both productions will contribute to the sustainability of the algae-biorefinery processes

Quality in Higher Education and Satisfaction among Professors and Students

This research received external funding by Project HUM-983 (ITACA): “Research through transforming learning and contexts.” Principal Researcher: Eva María Olmedo-Moreno.The aim of this study was to analyze the significant differences in satisfaction with educational quality in higher education in Italy (Naples) among students and professors. The sample consisted of 501 higher education students and 121 professors, resulting in a total sample size of 622 subjects. Once the quality parameters of the instrument were determined, reliability was confirmed, and data collection was initiated. In order to analyze the results, a test of independent means (Student’s t-test) was performed, interrelating the variables of educational quality, concerning both management and satisfaction with higher education. Based on the results, we concluded that there are significant differences between the group of students and the group of professors, highlighting a higher level of satisfaction with quality reported by students regarding the coordination of teachers and staff in the educational process; therefore, the inclusion of students in the direct management of the center should be more active and an indicator to be taken into account in self-evaluation. Despite the limitations in the sample at the regional level, it offers many possibilities for future research.HUM-98

Validation of the Smart City as a Sustainable Development Knowledge Tool: The Challenge of Using Technologies in Education during COVID-19

The objective of this research was to design and validate a questionnaire for teachers on the knowledge and use of smart city concepts and their usefulness in online learning during the COVID-19 pandemic based on a sustainable approach at different educational levels. It is important to analyze the use of online education based on the construction of intelligent learning environments, which favor the interaction between the environment and the student. With a quasi-experimental methodology, the psychometric properties of the questionnaire were analyzed through structural equation modeling (SEM), and the model was adjusted through a multivariate regression analysis to relate response patterns to a set of latent factors that cannot be directly observed, but exist in continuous dimensions of the people evaluated, and to create a valid and reliable instrument as a measurement tool using a sample of n = 973 subjects. The sample distribution consisted of 22.36% primary school teachers, 59.01% high school teachers, and 18.56% university teachers. The results showed a high reliability and construct validity through two models, and adjustment of the original model produced better goodness-of-fit parameters. We conclude that the designed questionnaire is a useful and valid tool for understanding how teachers have approached online teaching during the pandemic and their knowledge and use of Smart City concepts

Study on the Attitudes and Knowledge of Teachers and Future Teachers about Immediate Health Care Measures at School

The level and need for immediate health care measures training for teachers are of growing concern for two main reasons: on the one hand, these contents are part of the school curriculum and, on the other hand, teachers are the first adults to intervene in case of school injury. However, in Spain, first aid (FA) does not appear as obligatory content in the university training of teachers. The aim of the present study was to design and validate a questionnaire on the attitude of preschool and primary school teachers towards first aid knowledge adapted to the school context and to analyze its psychometric properties. First of all, the psychometric values of the questionnaire were tested: through its validation and reliability. Subsequently, a correlation study was carried out as well as a logistic regression in order to know the knowledge and attitudes of teachers and future teachers about the importance of the Immediate Attention Measures at school. The sample consisted of 392 participants: active teachers (71%) and future teachers (29%, the latter being final year students) of the infant and primary stages from the northern, central and southern areas of Spain. The results show adequate psychometric values, establishing three factors: attitude towards general knowledge in FA and learning methodology; attitude towards wounds and CPR algorithm (most frequent and/or serious events); self-perception of knowledge or skill in FA. Pearson’s correlation test identified significant values (p < 0.01) and positive association between Factors 1 and 2 (r = 0.422) and between 1 and 3 (0.244). The conclusions of the results of the validation process of the questionnaire on the attitude of teachers and future teachers to knowledge for immediate health care measures training are valid and reliable to an acceptable degree. Regression study demonstrates the importance of including first aid training in teachers’ degrees.INTEREDUC/UFM EDU2017-88641-Rproject "Study of training needs of the Autonomous City of Melilla"University of GranadaBusiness Consulting (ASME) 13/11_20Autonomous City of Melill
