There has been a growing interest in how teaching might be informed by "learning design" (LD), with a promising method for investigating LD being offered by the emerging field of "learning analytics" (LA). In this study, we used a novel LA for LD methodology to investigate the implementation of LD in an online distance learning context. A key innovation is the focus on "patterns" of LD. Using data from the virtual learning environment, outcomes data, and self-reports, for 47,784 students, we investigated the impact of those patterns on student behaviour, pass rates and satisfaction. A second innovation involves "social network analysis." Our study revealed that different patterns of LD were associated with statistically significant differences in behaviour, but not in pass rates or satisfaction. Nonetheless, the study highlights that applying LA to LD might, in a virtuous circle, contribute to the validity and effectiveness of both, and to the enhancement of online distance learning.

Purpose: The purpose of this paper is to evaluate the status of entrepreneurship education (EE) in Australia, replicating and expanding a similar study in 2015. The aim is to review neoteric global best practice EE initiatives, enabling the examination and embedding of EE offerings and initiatives at all 40 higher education institutions (HEIs) in Australia. Design/methodology/approach: The authors introduce a review of prominent and recent global EE scholarship, enabling an iterative and emergent inquiry perspective aligned to inductive and nascent multi-method empirical research associated with theoretical underpinnings of symbolic and substantive management theory. Findings: This paper highlights the sparse and inconsistent distribution of EE programs and initiatives across all 40 Australian HEIs, particularly against the backdrop of rapidly expanding start-up and entrepreneurship ecosystems. Furthermore, outcomes provide best practice EE initiatives, which included staff mobility and transferability of skills. HEIs in Australia are experiencing a moderate EE boom, albeit marginally down on global EE transformation initiatives. Research limitations/implications: Limitation of the data is subject to availability and accuracy of online documents and material resources, although implications have been mitigated using multi-method research design. Practical implications: The findings provide critical grounding for researchers, practitioners and HEIs wishing to enhance EE within ever-expanding entrepreneurship ecosystems. Originality/value: This study is the first multi-methods inquiry into the status of EE in Australia, consisting of quantitative, qualitative and algorithmic methods.

Objective To investigate factors associated with survival after out-of-hospital cardiac arrest in Viet Nam. Methods We did a multicentre prospective observational study of people (> 18 years) presenting with out-of-hospital cardiac arrest (not caused by trauma) to three tertiary hospitals in Viet Nam from February 2014 to December 2018. We collected data on characteristics, management and outcomes of patients with out-of-hospital cardiac arrest and compared these data by type of transportation to hospital and survival to hospital admission. We assessed factors associated with survival to admission to and discharge from hospital using logistic regression analysis. Findings Of 590 eligible people with out-of-hospital cardiac arrest, 440 (74.6%) were male and the mean age was 56.1 years (standard deviation: 17.2). Only 24.2% (143/590) of these people survived to hospital admission and 14.1% (83/590) survived to hospital discharge. Most cardiac arrests (67.8%; 400/590) occurred at home, 79.4% (444/559) were witnessed by bystanders and 22.3% (124/555) were given cardiopulmonary resuscitation by a bystander. Only 8.6% (51/590) of the people were taken to hospital by the emergency medical services and 32.2% (49/152) received pre-hospital defibrillation. Pre-hospital defibrillation (odds ratio, OR: 3.90; 95% confidence interval, CI: 1.54-9.90) and return of spontaneous circulation in the emergency department (OR: 2.89; 95% CI: 1.03-8.12) were associated with survival to hospital admission. Hypothermia therapy during post-resuscitation care was associated with survival to discharge (OR: 5.44; 95% CI: 2.33-12.74). Conclusion Improvements are needed in the emergency medical services in Viet Nam such as increasing bystander cardiopulmonary resuscitation and public access defibrillation, and improving ambulance and post-resuscitation care. Objectif Examiner les facteurs associes a la survie apres un arret cardiaque hors hopital au Viet Nam. Methodes Nous avons mene une etude d'observation prospective multicentrique sur des personnes (> 18 ans) ayant subi un arret cardiaque hors hopital (non traumatique) et admis dans trois hopitaux tertiaires au Viet Nam entre fevrier 2014 et decembre 2018. Nous avons recolte des donnees sur les caracteristiques, la gestion et l'issue de ces patients, puis les avons compares en fonction du moyen de transport vers l'hopital et de la survie apres leur admission. Enfin, nous avons mesure des facteurs associes a la survie lors de l'admission et de la sortie de l'etablissement a l'aide d'une analyse de regression logistique. Resultats Sur les 590 patients eligibles ayant subi un arret cardiaque hors hopital, 440 (74,6%) etaient des hommes et l'age moyen s'elevait a 56,1 ans (ecart type: 17.2). Seulement 24,2% (143/590) d'entre eux ont survecu a leur admission a l'hopital, et 14,1% (83/590) a leur sortie. La plupart des arrets cardiaques (67,8%; 400/590) ont eu lieu a domicile, 79,4% (444/559) se sont deroules en presence de passants et 22,3% (124/555) ont fait l'objet d'une reanimation cardiopulmonaire pratiquee par un temoin. A peine 8,6% (51/590) des patients ont ete emmenes a l'hopital par les services medicaux d'urgence, et 32,2% (49/152) ont recu une defibrillation avant d'arriver a l'hopital. La defibrillation prehospitaliere (odds ratio, OR: 3,90; intervalle de confiance de 95%, IC: 1,54-9,90) et le retablissement d'une circulation spontanee aux urgences (OR: 2,89; IC de 95%: 1,03-8,12) allaient de pair avec la survie apres admission. Lhypothermie therapeutique administree durant les soins post-reanimation etait liee a un meilleur taux de survie au moment de la sortie (OR: 5,44; IC de 95%: 2,33-12,74). Conclusion Des amenagements sont requis en matiere de services medicaux d'urgence au Viet Nam, notamment pour encourager la pratique de la reanimation cardiopulmonaire aupres de la population, garantir l'acces a des defibrillateurs publics, mais aussi ameliorer les soins en ambulance et en post-reanimation. Objetivo Investigar los factores relacionados con la supervivencia despues de un paro cardiaco extrahospitalario en Vietnam. Metodos Se realizo un estudio observacional prospectivo multicentrico de personas (>18 anos) que sufrieron un paro cardiaco extrahospitalario (no causado por traumatismo) en tres hospitales terciarios de Vietnam entre febrero de 2014 y diciembre de 2018. Se recopilaron los datos sobre las caracteristicas, el tratamiento y los resultados de los pacientes con paro cardiaco extrahospitalario y se compararon segun el tipo de transporte hasta el hospital y la supervivencia hasta el ingreso en el hospital. Se evaluaron los factores de supervivencia hasta el ingreso y el alta hospitalaria mediante un analisis de regresion logistica. Resultados De las 590 personas que cumplian los requisitos y sufrieron un paro cardiaco extrahospitalario, 440 (74,6 %) eran hombres, cuya edad media era de 56,1 anos (desviacion estandar: 17,2). Solo el 24,2 % (143/590) de estas personas sobrevivieron al ingreso en el hospital y el 14,1 % (83/590) sobrevivieron al alta hospitalaria. La mayoria de los paros cardiacos (67,8 %; 400/590) ocurrieron en el hogar, el 79,4 % (444/559) fueron presenciados por transeuntes y el 22,3 % (124/555) recibieron reanimacion cardiopulmonar por un transeunte. Solo el 8,6 % (51/590) de las personas fueron trasladadas al hospital por los servicios medicos de emergencia y el 32,2 % (49/152) recibieron desfibrilacion prehospitalaria. La desfibrilacion prehospitalaria (oportunidad relativa, OR: 3,90; intervalo de confianza del 95 %, IC: 1,54-9,90) y la recuperacion de la circulacion espontanea en el servicio de urgencias (OR: 2,89; IC del 95 %: 1,03-8,12) se asociaron a la supervivencia hasta el ingreso hospitalario. La hipotermia terapeutica durante la atencion posterior a la reanimacion se asocio a la supervivencia hasta el alta (OR: 5,44; IC del 95 %: 2,33-12,74). Conclusion Se necesitan mejoras en los servicios medicos de emergencia de Vietnam, como el aumento de las intervenciones de reanimacion cardiopulmonar para transeuntes y de desfibrilacion de acceso publico, asi como el mejoramiento de la atencion en las ambulancias y de los cuidados posteriores a la reanimacion.

We explore the use of smartphones to decode data transmitted from LEDs to smartphone cameras in visible light communication (VLC) applied to indoor positioning applications. The LEDs—modified to enable rapid on-off keying—transmit identification codes or optically encoded location data imperceptible to human perception. Equipped with a camera, the smartphone employs a single framed image to detect the presence of the luminaires in the image, decode their transmitted identifiers or locations, and determine the smartphone's position and orientation relative to the luminaires. The camera captures and processes images continuously. The following fundamental issues are addressed in this research: (i) analyzing the camera parameters on smartphones that affect data decoding results; (ii) exploiting the rolling shutter effect of the CMOS image sensor to receive multiple bits of data encoded in the optical communication line with a single frame shot; (iii) advancing research in developing algorithms to process data from multiple LEDs simultaneously. We conduct experiments to evaluate and analyze feasibility, as well as the challenges of the design, through scenarios varying in distance, transmission frequency, and data length.
