Introduction: latest advancements in audiovisual translation education

The consumption of audiovisual content, from the more traditional animations, documentaries, movies, and TV shows to the more recent online user-generated content found on social media platforms, including video games, has grown exponentially over the last few decades. The omnipresence of screens in society has led to transformations in audiences’ watching habits, now impatient to enjoy their programmes as soon as possible and inclined to binge watch. Recent technological advances in the production of specialist audiovisual translation (AVT) software and web-based applications have paved the way for further changes and enhancements in the ways professionals localise audiovisual content and in the nature of the services provided. This special issue sheds light on the current teaching and learning practices, methodologies and issues encountered by translator trainers specialised in AVT, with particular emphasis on pedagogical innovation, media accessibility, and translation technology

External quarantine of artiodactils wildlife from Namibia to Cuba

In Cuba for several years not imported wild animals from the African continent and this important donation was received from Namibia called Noah?s Ark II, considered the largest held in the country?s history. The present study shows the results of external quarantine of the 8 species of artiodactyls introduced in the country and with final destination at the National Zoo Park. Artiodactyls species were identified as African Buffalo (Syncerus caffer), Cape Eland (Taurotragus oryx), Roan Antelope (Hippotragus equinus), Greater Kudu (Tragelaphus strepsiceros), Hartebeest (Alcelaphus lichtensteinii), Gemsbok or Oryx (Oryx gazella), Impala (Aepyceros melampus) and Springbok (Antidorcas marsupiales). One hundred nine animals were investigated against 20 diseases. The laboratory results showed that 74.3% of all animals in quarantine were negative for 15 of the 20 diseases, 4% trypanosomiasis suspects and 22% positive for bluetongue, theileriosis, anaplasmosis and epizootic hemorrhagic disease. Sex relating these results showed that the highest percentage of negative animals appeared in populations with 77% females, while in males was lower with 69%. Arrived in the country a total of 59 adults and 5 calf Springbok meeting with the evaluate aspects and points made in the import protocol, so as apparently healthy animals and serologically negative to diseases of interestFil: Bolaños, R.

Subtitlers on the Cloud: The Use of Professional Web-based Systems in Subtitling Practice and Training

The bourgeoning and rapid evolution of cloud-based applications has triggered profound transformations in the audiovisual translation (AVT) mediascape. By drawing attention to the major changes that webbased ecosystems have introduced in localisation workflows, we set out to outline ways in which these new technological advances can be embedded in the AVT classroom. Along these lines, the present study sets out to explore the potential benefits of cloud platforms in AVT training curricula by exploring ways in which this technology can be exploited in subtitling training. An analysis of current subtitling practices and tools, localisation workflows, and in-demand skills in the AVT industry will be followed by an experience-based account on the use of cloud-based platforms in subtitler training environments to simulate and carry out a wide range of tasks. Our study pivots around the idea that cloud subtitling might prove useful to bridge the technological gap between academic institutions and the profession as well as to enhance the distance-learning provision of practice-oriented training in subtitling

Review of the occurrence and management of <i>Sotalia</i> bycatch in Central and South American coastal and riverine fisheries: priorities for immediate action

Despite the fact that cetacean bycatch has been acknowledged as the “greatest immediate and well documented threat to the survival of cetacean species and populations… …progress at reducing the scale and conservation impact of cetacean bycatch has been slow, sporadic, and limited to a few specific fisheries or circumstances “. In this paper, we 1) Review the occurrence of Sotalia bycatch all along its distribution area, 2) Examine how the problem has been addressed in some areas and 3) Outline some priority actions for conservation of the genus regarding management of bycatch issues. A recent review of cetacean bycatch in the Wider Caribbean Region indicates that mortality of Sotalia in fisheries-related operations with gillnets occurs in Colombia, French Guyana, Honduras, Surinam and Venezuela. Bycatch is also reported in Brazil, Nicaragua and Peru. Some mitigative measures including a ban on fisheries in protected areas, monitoring programs and field surveys for evaluation of bycatch have been made or are planned in Costa Rica and Venezuela. In Brazil, bycatch of Sotalia has been widely documented in coastal areas and also in the Amazon River Basin. In this country, an official action plan for the conservation of aquatic mammals includes specific recommendations to evaluate the impact of bycatch and to develop mitigative measures. According to recent statistics, most of cetacean bycatch worldwide occurs in gillnet fisheries. A precautionary approach suggests that – to protect Sotalia and other cetacean populations-these fisheries should be either regulated, monitored, limited or -in some instances – banned, taking into account that creative solutions should be provided by means of collaborative efforts between resource managers, fishermen, scientists and interested parties. On the other side, because of the socioeconomic aspects involved in such a decision, appropriate alternatives and/or incentives as well as local characteristics of some fisheries must be properly considered

Unparticle physics and neutrino phenomenology

We have constrained unparticle interactions with neutrinos and electrons using available data on neutrino-electron elastic scattering and the four CERN LEP experiments data on mono photon production. We have found that, for neutrino-electron elastic scattering, the MUNU experiment gives better constraints than previous reported limits in the region d>1.5. The results are compared with the current astrophysical limits, pointing out the cases where these limits may or may not apply. We also discuss the sensitivity of future experiments to unparticle physics. In particular, we show that the measurement of coherent reactor neutrino scattering off nuclei could provide a good sensitivity to the couplings of unparticle interaction with neutrinos and quarks. We also discuss the case of future neutrino-electron experiments as well as the International Linear Collider.Comment: 20 pages, 5 figures. Minor changes, final versio

Encapsulation of gold nanostructures and oil-in-water nanocarriers in microgels with biomedical potential

Indexación: Scopus.Funding: This research was funded by FONDECYT 1161450, 1150744, 11130494 and 1170929, FONDEQUIP EQM160157, EQM170111, CONICYT-FONDAP 15130011, and CONICYT PhD Scholarship 21141137.Here we report the incorporation of gold nanostructures (nanospheres or nanorods, functionalized with carboxylate-end PEG) and curcumin oil-in-water (O/W) nanoemulsions (CurNem) into alginate microgels using the dripping technique. While gold nanostructures are promising nanomaterials for photothermal therapy applications, CurNem possess important pharmacological activities as reported here. In this sense, we evaluated the effect of CurNem on cell viability of both cancerous and non-cancerous cell lines (AGS and HEK293T, respectively), demonstrating preferential toxicity in cancer cells and safety for the non-cancerous cells. After incorporating gold nanostructures and CurNem together into the microgels, microstructures with diameters of 220 and 540 µm were obtained. When stimulating microgels with a laser, the plasmon effect promoted a significant rise in the temperature of the medium; the temperature increase was higher for those containing gold nanorods (11–12 ◦ C) than nanospheres (1–2 ◦ C). Interestingly, the incorporation of both nanosystems in the microgels maintains the photothermal properties of the gold nanostructures unmodified and retains with high efficiency the curcumin nanocarriers. We conclude that these results will be of interest to design hydrogel formulations with therapeutic applications. © 2018 by the authors.https://www.mdpi.com/1420-3049/23/5/120

Serious Games Application for Memory Training Using Egocentric Images

Mild cognitive impairment is the early stage of several neurodegenerative diseases, such as Alzheimer's. In this work, we address the use of lifelogging as a tool to obtain pictures from a patient's daily life from an egocentric point of view. We propose to use them in combination with serious games as a way to provide a non-pharmacological treatment to improve their quality of life. To do so, we introduce a novel computer vision technique that classifies rich and non rich egocentric images and uses them in serious games. We present results over a dataset composed by 10,997 images, recorded by 7 different users, achieving 79% of F1-score. Our model presents the first method used for automatic egocentric images selection applicable to serious games.Comment: 11 page
