Influence of academic self-efficacy on adaptation to college: mediating role of academic emotional exhaustion and academic engagement

El objetivo de esta investigación fue analizar el rol mediador del agotamiento emocional académico (AEM) y del engagement académico (EA) en la influencia de la autoeficacia académica (AA) sobre las dimensiones de la adaptación a la universidad (AU) en estudiantes universitarios peruanos de nuevo ingreso. Participaron 688 estudiantes de universidades privadas (56.105% mujeres; Medad = 19.576; DTedad = 5.230). El análisis de datos se realizó mediante un análisis de regresión estructural y los parámetros se interpretaron bajo una perspectiva de magnitud del efecto. Respecto a los resultados, sin considerar los mediadores, se encontró que existe una influencia significativa de la AA sobre todas las dimensiones de la AU. Por otro lado, y al considerar al rol mediador del AEM y del EA dentro del modelo, solo se encontró una influencia indirecta y significativa de la AA a través del EA sobre tres dimensiones de la AU (académica, institucional y social). En conclusión, el EA media la influencia de la AA sobre las dimensiones de la AU, mientras que el rol mediador del AEM no está clarificado.The aim of this research study was to analyze the mediating role of academic emotional exhaustion (AEE) and academic engagement (AE) in the influence of academic self-efficacy (AS) on the dimensions of adaptation to college (AC) in Peruvian freshmen. A total of 688 Peruvian students from private universities participated (women = 56.105%; Mage = 19.576 years; SDage = 5.230 years). The data analysis was carried out under structural regression analysis and the parameters were interpreted under an effect size perspective. Regarding the results, without considering the mediators, a significant influence of the AS on all dimensions of AC was found. By other hand, when the mediating role of AEE and AE were considered into the model, only an indirect and significant influence of AS through the AE on three dimensions of AC (academic, institutional, and social) was found. It can be concluded that the AE mediates the influence of AS on the AC, while the mediating role of AEE is not yet clarified

Evaluating Indoor Positioning Systems in a Shopping Mall: The Lessons Learned From the IPIN 2018 Competition

The Indoor Positioning and Indoor Navigation (IPIN) conference holds an annual competition in which indoor localization systems from different research groups worldwide are evaluated empirically. The objective of this competition is to establish a systematic evaluation methodology with rigorous metrics both for real-time (on-site) and post-processing (off-site) situations, in a realistic environment unfamiliar to the prototype developers. For the IPIN 2018 conference, this competition was held on September 22nd, 2018, in Atlantis, a large shopping mall in Nantes (France). Four competition tracks (two on-site and two off-site) were designed. They consisted of several 1 km routes traversing several floors of the mall. Along these paths, 180 points were topographically surveyed with a 10 cm accuracy, to serve as ground truth landmarks, combining theodolite measurements, differential global navigation satellite system (GNSS) and 3D scanner systems. 34 teams effectively competed. The accuracy score corresponds to the third quartile (75 th percentile) of an error metric that combines the horizontal positioning error and the floor detection. The best results for the on-site tracks showed an accuracy score of 11.70 m (Track 1) and 5.50 m (Track 2), while the best results for the off-site tracks showed an accuracy score of 0.90 m (Track 3) and 1.30 m (Track 4). These results showed that it is possible to obtain high accuracy indoor positioning solutions in large, realistic environments using wearable light-weight sensors without deploying any beacon. This paper describes the organization work of the tracks, analyzes the methodology used to quantify the results, reviews the lessons learned from the competition and discusses its future

The IPIN 2019 Indoor Localisation Competition-Description and Results

IPIN 2019 Competition, sixth in a series of IPIN competitions, was held at the CNR Research Area of Pisa (IT), integrated into the program of the IPIN 2019 Conference. It included two on-site real-time Tracks and three off-site Tracks. The four Tracks presented in this paper were set in the same environment, made of two buildings close together for a total usable area of 1000 m 2 outdoors and and 6000 m 2 indoors over three floors, with a total path length exceeding 500 m. IPIN competitions, based on the EvAAL framework, have aimed at comparing the accuracy performance of personal positioning systems in fair and realistic conditions: past editions of the competition were carried in big conference settings, university campuses and a shopping mall. Positioning accuracy is computed while the person carrying the system under test walks at normal walking speed, uses lifts and goes up and down stairs or briefly stops at given points. Results presented here are a showcase of state-of-the-art systems tested side by side in real-world settings as part of the on-site real-time competition Tracks. Results for off-site Tracks allow a detailed and reproducible comparison of the most recent positioning and tracking algorithms in the same environment as the on-site Tracks
