Publicación Multivariate analysis of fuel consumption related to eco-driving: Interaction of driving patterns and external factors(Elsevier, 2021-03-01) Lois García, David; Wang, Yang; Boggio Marzet, Alessandra; Monzon, AndresEco-driving, as individual car-use behavior, is a cost-effective way of improving fuel efficiency, reducing CO2 emissions and other air pollutants like NOx. This paper aims to expand the knowledge on the short-term impacts of eco-driving by developing an analytical model of the key factors that explain fuel consumption and eco-driving, and to examine their relations in greater depth. Additionally, this paper analyses the effects on drivers’ stress levels after eco-driving. An eco-driving field trial is applied to collect real data of 1156 trips, using two vehicles and 24 drivers (42% Female; Age, M = 30.15; Years of driving experience, M = 10.30) in two Spanish cities with different road characteristics. A sequential method involving factor analysis, regression analysis and path analysis is used to analyze the sample. The results confirm that eco-driving is strongly affected by driving behavior like deceleration rate, RPM and speed, also showing that external factors as congestion and road slope have a direct influence on fuel consumption. The results also reveal that perceived stress levels vary among drivers, but there is not significant change when drivers eco driving.Publicación Prejudice against members of a ridiculed working-class group(Wiley, 2020-03-09) Vázquez Botana, Alexandra; Lois García, DavidIn five experiments, we examined the stereotypes, emotions, and behavioural intentions associated with a Spanish working-class group, known as chonis. We described a student (Experiments 1–3) or job candidate (Experiments 4–5) and presented participants with a picture showing a woman characterized either as choni or posh (an upper-class group, Experiments 2–4) or with no picture (Experiments 1, 3–5). Depending on the condition, explicit information about her high social class (Experiment 1), performance (Experiment 3), or category (Experiment 5) was provided. Participants evaluated the candidate more negatively, felt less admiration, and were less willing to interact with her or to recommend her for a job when she was categorized as choni as compared to the other categories. These effects disappeared if the student/candidate had high socioeconomic status or performed excellently in the academic domain, but they were magnified for highly (vs. weakly) materialistic individuals. Class prejudice apparently has harmful effects on disadvantaged individuals, but can be mitigated by explicit information.Publicación Effect of health-promoting messages in television food commercials on adolescents’ attitudes and consumption: A randomized intervention study(Elsevier, 2021-03) Fernández-Escobar, Carlos; Monroy-Parada, Doris Xiomara; Ordaz Castillo, Elena; Lois García, David; Royo Bordonada, Miguel ÁngelIntroduction The HAVISA plan is a Spanish government's policy for the promotion of healthy lifestyles via health messages in television food advertisements. This study evaluated the positive or negative impact (health halo effect) of health messages on food choices and predisposition towards healthy habits of Spanish adolescents. Methods Randomized controlled study in 11–14 years old adolescents. The intervention group watched television advertisements for unhealthy foods with HAVISA health messages, while the control group watched the same advertisements without them. A self-administered questionnaire measured participants’ attitudes towards the products advertised, to diet and physical activity, and recognition of messages. Afterwards they chose between fruit and unhealthy snacks. The differences between the two groups were then compared. Results A total of 27.2% of the control group versus 29.6% of the intervention group chose fruit (p = 0.54). Both groups displayed high desire for (7.24 vs. 7.40, p = 0.29) and intention to consume (6.67 vs. 6.73, p = 0.63) the unhealthy products advertised. There were no differences in perceived healthiness of these foods (4.11 vs. 4.19, p = 0.74), or perceived importance of a healthy diet (3.17 vs. 3.12, p = 0.55) or physical activity (4.53 vs. 4.51, p = 0.73). Desire for vegetables (2.49 vs. 2.66, p = 0.08) and fruit (3.15 vs. 3.30, p = 0.09) were higher in the intervention group, but the differences were not significant. Only 47.6% of participants noticed the presence of health messages; of these, 31% correctly recalled their content. Conclusion HAVISA health messages changed neither the attitudes nor immediate eating behaviors of adolescents. There was no immediate healthy-lifestyle promoter or adverse health halo effect, probably due to the messages’ low prominence. Further research should evaluate the long-term effect of repeated exposure to health messages.Publicación The role of subjective socioeconomic status in predicting academic performance: exploring the mediating influence of sense of belonging among students in a distance learning university(Cambridge University Press, 2024-03-07) Vázquez Botana, Alexandra; Alba Langreo, Beatriz; Lois García, David; García Ael, Mª Cristina; Bustillos López, AntonioBuilding upon existing research conducted in face-to-face universities, our research explored whether, in the context of a distance learning institution, the positive association between subjective socioeconomic status and academic performance can be explained by students’ sense of belonging. To that end, we conducted a three-wave correlational study with 2,261 students enrolled in Social Psychology in a distance learning university. At the start of the academic year, we measured participants’subjective socioeconomic status relative to other students alongside their initial expectations in terms of time investment and grades and other relevant covariates. Midway through the course, we assessed their sense of belonging to the university and, at the end, we recorded their grades. Results suggested that sense of belonging potentially serves as a mediating factor in the positive relationship between subjective socioeconomic status and grades even after accounting for variables like initial grade expectations, time commitment, gender, age, and employment situation. These findings emphasize the pivotal role of students’ psychological connection to the university in shaping their academic achievement, even within the expanding landscape of distance education.Publicación Factores que influyen en la elección del transporte público o el automóvil como modo de transporte en los desplazamientos habituales(SAGE, 2014-05-01) López Sáez, Mercedes; Martínez Rubio, José Luis; Lois García, David; Fernández Sedano, IciarEl objetivo del presente trabajo es analizar, entre usuarios de transporte público y privado, las diferencias en actitudes hacia su modo de transporte habitual. Asimismo, se ha comprobado la capacidad explicativa de las actitudes para determinar la elección del modo de transporte, junto con los factores estructurales y sociodemográficos. El estudio se ha llevado a cabo en tres ciudades españolas, habiendo participado 742 personas. Los resultados revelan que el automóvil es mejor valorado que los modos públicos en los atributos asociados a ventajas inmediatas (p.e., rapidez o disponibilidad) y la comodidad. El metro es bien valorado tanto en ventajas inmediatas como en diferidas (medio ambiente, seguridad, coste y salud). El autobús es el modo menos valorado, en comparación con el resto. Mediante regresión logística se ha comprobado que la varianza explicada por un modelo en el que se incluyen las actitudes (R2 = .639) es mayor que la explicada por un modelo basado solamente en variables relacionadas con las infraestructuras (R2 = .489). La discusión de estos resultados se vincula con actuaciones dirigidas a disminuir el uso del automóvil.Publicación Are travellers willing to adopt MaaS? Exploring attitudinal and personality factors in the case of Madrid, Spain(Elsevier, 2021-10) Lopez Carreiro, Iria; Monzon, Andres; Lois García, David; Lopez Lambas, Maria E.Mobility as a Service (MaaS) is expected to significantly change our mobility patterns. However, it is still not clear who will accept this new mobility paradigm and how it will affect travellers’ behaviours. In this study, we identify a set of attitudinal and personality factors relevant for MaaS adoption based on a survey comprising 1,000 respondents in the metropolitan area of Madrid (Spain). The results show strong positive attitudes towards MaaS after being validated through a structural equation model. The higher the percentage of multimodal travellers, the more they are open to “new mobilities”, the greater their technological capabilities and curiosity, and the lower their cost sensitivity, then the higher the adoption potential for MaaS. Our analysis reveals four clusters in terms of individuals’ intention to use MaaS technologies (technological car-followers, unimodal travellers, MaaS-lovers and active public-transport supporters). Motivated by a significant environmental sensibility, MaaS-lovers appear to be the most likely to reduce their private car usage in favour of alternative modes. Overall, we recognise two main barriers that can frustrate MaaS adoption: low technology affinity and low openness to sharing-mobility services. Policies that focus on these two aspects can encourage MaaS acceptance.
