The importance of knowledge and trust for ethical fashion consumption

Purpose. The clothing industry is one of the most polluting industries in the world, although manufacturers and retailers are trying to revert this tendency by applying ethical fashion principles. Drawing on the knowledge-attitude-behavior (KAB) model or practice, this study aims to predict Chinese consumers' purchase intention of ethical fashion by employing and extending the theory of planned behavior (TPB). Design/methodology/approach. The extended TPB model incorporates knowledge of ethical fashion and trust in the fashion industry and two critical variables in ethical fashion literature to explain the purchase intention of ethical fashion. Primary data from 245 Chinese respondents were collected in 2019. The model was tested and analyzed through structural equation modeling (SEM). Findings. Results show that the extended TPB model has higher predictability than the original TPB model. Attitude toward ethical fashion and subjective norm significantly predicts purchase intention while perceived behavioral control (PBC) does not. In addition, trust of ethical fashion is positively related to attitude toward ethical fashion and purchase intention, whereas knowledge of ethical fashion plays a significant role in predicting trust and the three TPB factors. The subjective norm was found to have the most significant impact on consumers' intention to purchase ethical fashion, which shows that social pressure from one individual's reference group is the most dominant factor in forming consumer's purchase intention on ethical fashion. Originality/value. The findings enrich the past literature on ethical fashion that trusting belief is a salient determinant of consumers' attitude toward ethical fashion and purchase intention of ethical fashion products. The findings also supported the applicability of KAB and TPB in the domain of ethical consumption in the context of a developing country

An Empirical Exploration of the Perceived Effectiveness of a "Flipped Classroom" in a Business Communication Course

ABSTRACT: This paper explores a causal model, using Structural Equation Modelling (SEM), in order to understand how the perceived effectiveness of the "flipped classroom" and students' satisfaction with this technique can be affected by students' engagement in the "flipped classroom" activities as well as the complexity and task orientation of such activities. The findings of the study confirm that the perceived effectiveness of the "flipped classroom" can be calculated by its contribution to the improvement of students' general skills, knowledge and learning motivation. Students' engagement in the "flipped classroom" activities is the key factor influencing perceived effectiveness and students' satisfaction, while the complexity and task orientation of the "flipped classroom" also play a role in determining perceived effectiveness and satisfaction, although indirect and always mediated by engagement

Healthcare workers hospitalized due to COVID-19 have no higher risk of death than general population. Data from the Spanish SEMI-COVID-19 Registry

Aim To determine whether healthcare workers (HCW) hospitalized in Spain due to COVID-19 have a worse prognosis than non-healthcare workers (NHCW). Methods Observational cohort study based on the SEMI-COVID-19 Registry, a nationwide registry that collects sociodemographic, clinical, laboratory, and treatment data on patients hospitalised with COVID-19 in Spain. Patients aged 20-65 years were selected. A multivariate logistic regression model was performed to identify factors associated with mortality. Results As of 22 May 2020, 4393 patients were included, of whom 419 (9.5%) were HCW. Median (interquartile range) age of HCW was 52 (15) years and 62.4% were women. Prevalence of comorbidities and severe radiological findings upon admission were less frequent in HCW. There were no difference in need of respiratory support and admission to intensive care unit, but occurrence of sepsis and in-hospital mortality was lower in HCW (1.7% vs. 3.9%; p = 0.024 and 0.7% vs. 4.8%; p<0.001 respectively). Age, male sex and comorbidity, were independently associated with higher in-hospital mortality and healthcare working with lower mortality (OR 0.211, 95%CI 0.067-0.667, p = 0.008). 30-days survival was higher in HCW (0.968 vs. 0.851 p<0.001). Conclusions Hospitalized COVID-19 HCW had fewer comorbidities and a better prognosis than NHCW. Our results suggest that professional exposure to COVID-19 in HCW does not carry more clinical severity nor mortality

Information and Communication Technologies (ICT) and digital competence: What do students think?

RESUMEN A lo largo de mi experiencia como docente en prácticas pude constatar el empeño y la prioridad que se estaba dando al uso de las Tecnologías de la Información y de la Comunicación (TIC) en clase y a la adquisición de la competencia digital, de ahí nació la idea de un Trabajo Fin de Máster que versara sobre las TIC. El presente trabajo tratará de explicar cómo ha ido evolucionando la sociedad hasta conseguir convertir el uso de las TIC en algo necesario y básico para el desarrollo vital de cualquier persona. Continuará tratando de ejemplificar en un caso concreto, el I.E.S Nuestra Señora de los Remedios, que la inclusión de la TIC se está llevando a cabo en los centros educativos. Para ello, no se ha querido dejar pasar la oportunidad de detallar los planes, programas y proyectos TIC del centro. En última instancia, se procederá a llevar a cabo el análisis de los resultados de una encuesta TIC pasada a una muestra de alumnos del centro para conocer el verdadero estado de la cuestión.ABSTRACT Throughout my experience as a trainee teacher, I was able to verify the commitment and priority that was being given to the use of Information and Communication Technologies (ICT) in class and to the acquisition of digital competence from there was born the idea of a Master's End Work on ICT.

Synthesis and characterization of highly diluted polyanionic iron(II) spin crossover systems

Spin crossover (SCO) complexes, through their reversible spin transition under external stimuli, can work as switchable memory materials. Here, we present a protocol for the synthesis and characterization of a specific polyanionic iron SCO complex and its diluted systems. We describe steps for its synthesis and the determination of crystallographic structure of the SCO complex in diluted systems. We then detail a range of spectroscopic and magnetic techniques employed to monitor the spin state of the SCO complex in both diluted solid- and liquid-state systems. For complete details on the use and execution of this protocol, please refer to Galán-Mascaros et al. Publisher's note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics.

Molecular memory near room temperature in an iron polyanionic complex

International audienceBistable molecules represent a potential miniaturization limit for high-density information technologies. However, molecules exhibit memory effect typically at very low temperatures. This is the case of spin-crossover (SCO) complexes, where the concept of a molecular memory has not been considered due to the fast spin-state interconversion of all previous systems. Breaking this principle, here we report a slow relaxation process found in an SCO iron-triazole polyanionic complex. Multiple experimental evidences confirm the opening of a thermal hysteresis upon solid dilution and even in liquid solution. Density functional theory (DFT) calculations reveal the origin of this unexpected phenomenon to the appearance of an energy barrier that slows down the spin-state relaxation processes at the molecular level. These results show how SCO molecules may store information at room temperature, opening unique opportunities for molecular data storage

Molecular memory near room temperature in an iron polyanionic complex

Single molecules are the smallest processable units for information storage and sensing. However, molecular phenomena are typically limited to very low temperatures. Thermal energy is able to depopulate (erase) the excited state back to the ground state. Spin-crossover (SCO) molecules are an exception to this rule, showing memory effect above room temperature, but only when the electronic switchability is associated with a bulk phase transition. This synergy has its origin in the cooperativity among SCO molecules in the crystal, disappearing in diluted samples. We have found a surprising exception to this model: a polyanionic iron complex capable of showing memory effect even upon dilution. Our results demonstrate that molecular species can exhibit thermal hysteresis if intramolecular interactions are able to slow down the relaxation processes at the single-molecule level. Our findings open unprecedented opportunities for single-molecule memories at (and above) room temperature
