Sacrificed: Ontario Healthcare Workers in the Time of COVID-19.

Healthcare workers (HCWs) in Ontario, Canada have faced unprecedented risks during the COVID-19 pandemic. They have been infected at an elevated rate compared to the general public. HCWs have argued for better protections with minimal success. A worldwide shortage of N95s and comparable respirators appears to have influenced guidelines for protection, which stand at odds with increasing scientific evidence. In-depth interviews were conducted with ten frontline HCWs about their concerns. They reported that the risk of contracting COVID-19 and infecting family members has created intense anxiety. This, in conjunction with understaffing and an increased workload, has resulted in exhaustion and burnout. HCWs feel abandoned by their governments, which failed to prepare for an inevitable epidemic, despite recommendations. The knowledge that they are at increased risk of infection due to lack of protection has resulted in anger, frustration, fear, and a sense of violation that may have long-lasting implications.Sacrifié: Le personnel de la santé ontarien à l'époque de la COVID-19RésuméEn Ontario, au Canada, le personnel de la santé a eu à faire face à des risques sans précédent durant la pandémie de COVID-19. On y a constaté un taux d'infection plus élevé chez les travailleuses et travailleurs de la santé (TTS) qu'au sein de la population en général. Les TTS ont revendiqué des moyens de protection améliorés, sans grand succès. Une pénurie mondiale de masques respirateurs de type N95 ou similaires semble avoir joué sur les directives en matière de protection, qui ne cadrent pas avec une accumulation de preuves scientifiques. Lors d'entretiens en profondeur, dix TTS de première ligne ont été invités à donner leur avis sur la situation. à les entendre, le risque de contracter la COVID-19 et d'infecter les membres de leur famille leur cause beaucoup d'anxiété. Associée à un manque de personnel et à une charge de travail accrue, cette anxiété se traduit par un épuisement physique et professionnel. Les TTS se sentent abandonnés par leurs gouvernements, qui ont manqué de se préparer à l'inévitabilité d'une épidémie, malgré ce qui leur avait été recommandé. Leur réalisation d'être exposés à un plus grand risque d'infection par manque d'équipement de protection s'est muée en colère, frustration et peur, et en un sentiment de violation de leurs droits dont on peut craindre qu'il subsiste fort longtemps.

The MARS2013 Mars analog mission.

We report on the MARS2013 mission, a 4-week Mars analog field test in the northern Sahara. Nineteen experiments were conducted by a field crew in Morocco under simulated martian surface exploration conditions, supervised by a Mission Support Center in Innsbruck, Austria. A Remote Science Support team analyzed field data in near real time, providing planning input for the management of a complex system of field assets; two advanced space suit simulators, four robotic vehicles, an emergency shelter, and a stationary sensor platform in a realistic work flow were coordinated by a Flight Control Team. A dedicated flight planning group, external control centers for rover tele-operations, and a biomedical monitoring team supported the field operations. A 10 min satellite communication delay and other limitations pertinent to human planetary surface activities were introduced. The fields of research for the experiments were geology, human factors, astrobiology, robotics, tele-science, exploration, and operations research. This paper provides an overview of the geological context and environmental conditions of the test site and the mission architecture, in particular the communication infrastructure emulating the signal travel time between Earth and Mars. We report on the operational work flows and the experiments conducted, including a deployable shelter prototype for multiple-day extravehicular activities and contingency situations.

Field trial of a dual-wavelength fluorescent emission (L.I.F.E.) instrument and the Magma White rover during the MARS2013 Mars analog mission.

Abstract We have developed a portable dual-wavelength laser fluorescence spectrometer as part of a multi-instrument optical probe to characterize mineral, organic, and microbial species in extreme environments. Operating at 405 and 532 nm, the instrument was originally designed for use by human explorers to produce a laser-induced fluorescence emission (L.I.F.E.) spectral database of the mineral and organic molecules found in the microbial communities of Earth's cryosphere. Recently, our team had the opportunity to explore the strengths and limitations of the instrument when it was deployed on a remote-controlled Mars analog rover. In February 2013, the instrument was deployed on board the Magma White rover platform during the MARS2013 Mars analog field mission in the Kess Kess formation near Erfoud, Morocco. During these tests, we followed tele-science work flows pertinent to Mars surface missions in a simulated spaceflight environment. We report on the L.I.F.E. instrument setup, data processing, and performance during field trials. A pilot postmission laboratory analysis determined that rock samples acquired during the field mission exhibited a fluorescence signal from the Sun-exposed side characteristic of chlorophyll a following excitation at 405 nm. A weak fluorescence response to excitation at 532 nm may have originated from another microbial photosynthetic pigment, phycoerythrin, but final assignment awaits development of a comprehensive database of mineral and organic fluorescence spectra. No chlorophyll fluorescence signal was detected from the shaded underside of the samples.

A case for using ground-based thermal inertia measurements to detect Martian caves.

Martian caves are regarded as one of the most interesting locations in which to search for life on the planet. Data obtained during the MARS2013 expedition at Hamar Laghdad Ridge in the Tafilalt region of Morocco indicate that even small cavities can display thermal behavior that is characteristic for caves. For example, temperature in a cavity equaled 14°C±0.1°C before sunrise, which was higher than the temperature of the ambient air (10°C±0.1°C) and proximate rocks (9°C±0.1°C) at the same time. Within 30 min after sunrise, when the temperature of surrounding rocks corresponded to 15°C, this thermal relationship reversed. Measurements were conducted under simulated spaceflight conditions, including near-real-time interpretation of data that were acquired in a complex flight planning environment. We conclude that using ground-based thermal contrast measurements, in 7-14 µm band before and after sunset, is an effective method for Mars astronauts to identify caves, possibly superior to usage of space-based or ground-penetrating data.

'Thinking for two': a case study of speech and language therapists working through assistants.

BACKGROUND: Many speech and language therapists (SLTs) in the UK work with speech and language therapy assistants, and the numbers of SLT assistants is expected to grow. There has been very little empirical investigation of how SLTs feel about this situation or the effect on working practices of working indirectly. AIMS: To investigate SLTs' opinions on working with SLT assistants in a small-scale research case study. METHODS AND PROCEDURES: The study design was a case study of five SLTs delivering intervention within a research intervention project. Prepared questionnaire and formal interview techniques were used to elicit opinions on working through assistants, and a content analysis was performed. OUTCOMES AND RESULTS: Although respondents could see value in working through assistants, they stressed the time required to do so and the difficulties of adapting and updating therapy plans when working indirectly. CONCLUSIONS: The study suggests a variety of factors that have to be carefully managed if SLTs are to work competently through assistants.
