A system to obtain vehicular energy‐use and emissions in transient traffic is proposed. It operates at a microscopic 1‐s time scale, capturing critical stop‐and‐go dynamics in a controlled and repeatable computational environment. This allowed the definition of a sensitivity function linking energy‐use to traffic flow, providing an additional comparison parameter. To obtain the dynamics data, crucial for transient traffic modeling implementation and validation, a video‐tracking technique is used to overcome velocimeter and GPS data shortcomings. This approach allowed to observe and reproduce a traffic scene and agreed with a M/D/n queuing traffic model. Once the system contains precise dynamics, it can be implemented for traffic scenarios such as intersections, school areas, or future road projects. Any simulated vehicular technology can be incorporated into the analysis. A case study was implemented using 1000 electric (EV) and combustion engine vehicles (CV) interacting with trucks, buses, and motorcycles, while monitoring individual vehicular systems. These included the powertrain and regenerative braking to obtain energy‐use and emissions. EVs proved to be not only more efficient, but less sensitive to traffic buildup than CVs. The techniques presented here, lend themselves to technological design and evaluation and allows testing real‐life vehicular systems for sustainable traffic and energy planning.

Introduction : in 2014 hundreds of teenage women in the rural municipality of El Carmen de Bolivar (Colombia) experienced strange symptoms after being vaccinated with Gardasil, one of the vaccines against Human Papillomavirus (HPV). Health authorities did not find a causal link between the vaccination and the symptoms, so they attributed the phenomenon to a possible massive psychogenic reaction. The families of those affected rejected this hypothesis. The case revealed the existence of a controversy among the Colombian scientific community about the safety of the vaccine. The persistence over time of the health problem and its massive nature influenced a drastic decline in vaccination coverage, and the Constitutional Court ruled in 2017 on the mandatory use of informed consent during the vaccination procedure. Methodology : an updated comprehensive narrative review of the literature published between 2014 and 2021 is presented. A synthesis of the scientific information available in Medline, Pubmed, Cochrane, Scielo, Redalyc and Google Scholar was performed. Results : 37 texts were identified, and a categorization of analysis was established in 4 groups: a possible massive psychogenic reaction, a possible adverse reaction to the vaccine, the need to broaden the epistemological approach to understand the phenomenon and a controversy in the Colombian scientific field. Conclusions : the review shows that the application of the HPV vaccine has generated a public health problem whose nature is still controversial, due to the difficulty in identifying an etiological diagnosis of the symptoms of those affected.

Journalistic autonomy has been studied more frequently in countries with secure democracies in terms of journalists' perceptions of freedom and independence to work in the midst of the controls, pressures, and influences perceived in the newsrooms. Based on objective variables and on a national survey completed by 546 Colombian journalists, this article examines how inequality, violence, and insecurity affect their perceived autonomy to develop and publish news. Using regression analysis and statistical mediation, it was found that political and economic influences intervene in the relationship between aggressions against journalists and the decrease in journalistic autonomy. This decrease is strongest when violence comes internally from the work environment and when gender inequalities, homicides, and insecurity are connected to newsrooms. In the conclusion, recommendations are offered for future studies and postagreements of peace in Colombia. [ABSTRACT FROM AUTHOR]

Travel stories form part of a great tradition inside Western Culture which has served historically to describe, to understand and to imagine other cultures and communities, far or near, being constituted into a real narrative genre. This type of story has been and is a reflection of the perception of the world based on the imaginary worlds created by the travelling narrators. How do modern authors of travel stories take advantage of the opportunities offered by transmedia storytelling? The present article explores the potential of these types of stories as a privileged object of study for transmedia storytelling studies, from the analysis of a sample of 80 narrative productions based on experiences of travel and presented in diverse editions of the Festival Le Grand Bivouac (France). It also shows the existence of a new contemporary trend inside this narrative form that transcends its literary nature. [ABSTRACT FROM AUTHOR]
