"Influencia de la verosimilitud de la historia y los personajes identificables de un spot narrativo en la actitud del público hacia el spot y la marca"

La persuasión narrativa es efecto del transporte narrativo, que se manifiesta en la actitud del receptor al ser arrastrado por una historia. La verosimilitud de la historia y los personajes identificables pueden influir en el transporte narrativo. La intensidad de la experiencia narrativa y la reducción de cuestionamiento a los argumentos hace a las historias particularmente eficaces para influir en las actitudes. La presente investigación busca indicar de qué manera la verosimilitud en la historia y los personajes identificables en un spot narrativo pueden influenciar en la actitud del público hacia el spot y la marca. Se escogió el análisis de contenido, los focus group y tres escalas de medición de actitudes como instrumentos. Se descubrió que la narrativa afecta de manera positiva la actitud hacia la marca y permite comunicar un mensaje más profundo y mayor contenido. La influencia de las dos variables se refleja en la aceptación de la historia y de los personajes por parte del público. El público se conecta con el mensaje y transmite lo que siente por la historia hacia la marca y cambia la actitud que tiene hacia ella. La emoción presente en la narrativa es uno de los elementos que originó empatía con la historia y el impacto del mensaje

Tracking kelp-type seaweed fuel in the archaeological record through Raman spectroscopy of charred particles: examples from the Atacama Desert coast

The use of seaweed as fuel has been mentioned in ethnographic and historical sources of different coastal regions. Nevertheless, the archaeological record of seaweed burning is still limited to contexts where preservation is exceptional and macroscopic discrimination of charred remains is possible. Here, we evaluate the effectiveness of Raman spectroscopy in discriminating seaweed vs. plant/wood char. Our dataset (N = 92) consists of modern and archaeological seaweed and plant/wood charred remains, including specimens of unknown origin from the Atacama Desert coast, Northern Chile. The charred samples were processed to obtain 13 parameters which were then fed into five supervised machine learning models. The models, built on samples of known origin (seaweed and plant/wood), performed remarkably well in terms of accuracy, kappa, sensitivity, and specificity. The models were used for final predictions on 10 non-identified archaeological charcoals. Our results suggest that Raman spectroscopy combined with machine learning techniques is a robust methodology for discriminating seaweed and plant/wood charred remains in the archaeological record. The predictions on unknown samples confirm that seaweed was used as fuel in a specific funerary ritual in the southern Atacama Desert coast around 5000 cal BP. Furthermore, charred specimens of Lessonia spp. recovered from combustion features in other northern Chile coastal settlements, suggest that seaweed pyrotechnology developed by Atacama Desert coast people is likely a long-term process. As for coastal archaeology, this work encourages new research on seaweed as an alternative/main fuel in coastal deserts and evaluates possible bias for chronologies from coastal archaeological settlements around the globe.The present study was supported by the Universidad de Tarapacá (Chile) through the research grants UTA MAYOR 3754 (2021–2022) – “Uso de algas como combustible en sitios arqueológicos de la costa desértica de Atacama: una aproximación arqueomética” and UTA MAYOR 367122 (2022–2024) – “Estudio multiproxy para el reconocimiento de algas en rasgos de combustión arqueológicos de la costa del Desierto de Atacama” (Universidad de Tarapacá, Chile).

The studied samples were obtained during archaeological excavations or samplings performed in the following projects: FONDECYT 1151203; FONDECYT POSTDOC 3150664; and Quebrada Blanca Phase 2 (QB2) project – Compañía Minera Teck Quebrada Blanca S.A

Cross-cultural validation of the new version of the Coronavirus Anxiety Scale in twelve Latin American countries

The Coronavirus Anxiety Scale (CAS) was recently developed to assess dysfunctional anxiety related to COVID-19. Although different studies reported that the CAS is psychometrically sound, it is unclear whether it is invariant across countries. Therefore, the present study aimed to examine the measurement invariance of the CAS in twelve Latin American countries (Argentina, Bolivia, Chile, Colombia, Cuba, Ecuador, El Salvador, Guatemala, Mexico, Paraguay, Peru, and Uruguay). A total of 5196 people participated, with a mean age of 34.06 (SD = 26.54). Multigroup confirmatory factor analysis (CFA) was used to examine the measurement invariance of the CAS across countries and gender. Additionally, the graded response model (GRM) was used to provide a global representation of the representativeness of the scale with respect to the COVID19 dysfunctional anxiety construct. The unidimensional structure of the five-item CAS was not confirmed in all countries. Therefore, it was suggested that a four-item model of the CAS (CAS-4) provides a better fit across the twelve countries and reliable scores. Multigroup CFA showed that the CAS-4 exhibits scalar invariance across all twelve countries and all genders. In addition, the CAS-4 items are more informative at average and high levels of COVID-19 dysfunctional anxiety than at lower levels. According to the results, the CAS-4 is an instrument with strong cross-cultural validity and is suitable for cross-cultural comparisons of COVID-19 dysfunctional anxiety symptoms in the general population of the twelve Latin American countries evaluated

COVID-19 anxiety, psychological well-being and preventive behaviors during the COVID-19 pandemic in Latin America and the Caribbean: relationships and explanatory model

This study assesses the relationship between COVID-19 anxiety and subjective well-being in terms of the mediating role of COVID-19 preventive behaviors. Additionally, the contribution of sociodemographic factors (sex and age) and risk perception on COVID-19 anxiety and its potential measurement invariance was tested in 5655 participants from 12 countries in Latin America and the Caribbean. A mixture of both latent and observable variables were analyzed using a system of structural equations. The Coronavirus Anxiety Scale (CAS), Preventive COVID-19 Infection Behaviors Scale (PCIBS) and single-item measures were used to assess the perceived probability of death, perceived severity and concern about transmitting COVID-19. The results indicated that there is a significant and relevant direct effect of COVID-19 anxiety on participants' well-being. Furthermore, COVID-19 anxiety significantly predicted both preventive behavior (β =.29, p <.01) and well-being (β = –.32, p <.01). The effects of COVID anxiety and preventive behavior explained 9.8% of the variance in well-being (R-square =.098); whereas, 8.4% of the variance in preventive behavior was associated with COVID anxiety (R-square =.084). Likewise, perceived likelihood of death from COVID, perceived severity of COVID, and concerns about COVID transmission were positively related to anxiety. Age was negatively related to anxiety, with men being less anxious than women. The results are invariant by country, i.e., the broad relationships found in the combined sample are also present in each individual country. The findings indicate that, although the exact relationships between variables may vary between countries, there are enough similarities to provide useful information about the impact of the COVID-19 pandemic in each of the countries included in the study

La influencia de los cambios tecnológicos se visualiza en todos los aspectos que conciernen a la sociedad, entre ellos la educación. A pesar de que se han dado exitosas aplicaciones de las tecnologías de la información y comunicación en este ámbito, existen temas como la aplicación práctica de conocimientos obtenidos en investigaciones que no han sido resueltos del todo y más aún en el ámbito de la Planificación Territorial y Urbana, en donde es común encontrar un sinnúmero de dificultades al momento de realizar una transmisión de resultados de investigación a la mayoría de potenciales usuarios (cuyo acceso al material científico es limitado), e incluso las restricciones que tienen las instancias encargadas de la planificación en el país de comunicar sus propuestas metodológicas y validarlas en un ambiente académico.The influence of technological changes is displayed in all aspects that relate to society, including education. While successful applications of information and communication technologies have occurred in this area, there are issues such as the practical application of knowledge gained in investigations that have not been solved such as the case of Territorial Planning and Urban. In this field it is common to find a countless of difficulties when making a transmission of results of research the majority of potential users (whose access to scientific material it is limited), and even the restrictions that have instances responsible for planning to communicate their methodological proposals and validate them in an academic environment.Cuencanúmero
