Many search and rescue workers voluntarily interrupt their lives ...when they are called upon to help strangers. They awake in the middle of the night to cover miles of terrain in search of lost hikers or leave work to search potential avalanche zones for missing skiers, snowboarders, and snowmobilers in blizzard conditions. They often put their own lives in danger to rescue stranded, hypothermic kayakers and rafters from rivers.
Drawing on six years of participant observation and in-depth interviews, Jennifer Lois examines the emotional subculture of “Peak,” a volunteer mountain-environment search and rescue team. Rescuers were not only confronted by physical dangers, but also by emotional challenges, including both keeping their own emotions in check during crisis situations, and managing the emotions of others, such as those they were rescuing. Lois examines how rescuers constructed meaning in their lives and defined themselves through their heroic work.
Heroic Efforts serves as an easy to understand sociological introduction to the ways emotions develop and connect us to our surroundings, as well as to the links between the concept of heroism and other sociological theories such as those on gender stereotypes and edgework.
High altitude mountaineering is characterized by high energetic requirements due to the environment in which the activity is developed: negative energy balance, extreme cold, high altitude and the ...assumption of potential risks can be found during the practice of this sport. High altitude mountaineering, as a result of the previous factors, induces changes in body composition which have never been studied previously in a systematic review. A search within four different databases (PubMed, SportDiscus, Scopus and Medline) was performed using the thesaurus terms "Mountaineering" and "Body composition". A second search was performed using the following terms "Altitude" and "Body composition". The selection criteria included studies with healthy adults which evaluated the effects of at least 14 days of uninterrupted stays at altitudes above 4,000 m. The studies included in the review assessed body composition through different methods such as anthropometry, bioimpedance, dual energy x-ray absorptiometry, hydrostatic weighing and air displacement plethysmography. The search was performed up to and including December 1st 2018. Eleven observational studies met the inclusion criteria. All studies reported weight loss, of which five reported significant reductions in lean mass and six reported reductions in fat mass. Also, three studies reported reductions in both fat mass and lean mass. Current evidence is limited to observational studies with important confounding factors affecting the final conclusions. Longitudinal studies with a better methodological design and control groups are needed in order to verify these results.
•Safety voice is the act of speaking up about safety to prevent physical harm.•Conceptually related to employee voice, safety voice has unique scope due to its emphasis on harm.•It is ecological: ...predictors, pragmatics and outcomes are found across levels of analysis.•Important challenges for safety voice remain in developing methodologies and interventions.
Safety voice is the act of speaking up about safety in order to prevent accidents and physical harm. It occurs across contexts (e.g., healthcare, aviation, construction, mountaineering, high-risk sports) and understanding the phenomenon enables interventions. Despite recent interest, however, it remains unclear how safety voice (i) differs conceptually from employee voice, (ii) is delineated across levels of analysis, and (iii) could be optimally investigated. Addressing this, we identified 48 articles, and integrated 256 safety voice antecedents, 7 pragmatics and 23 outcomes into an ecological framework. Overlap was found with employee voice concepts and methodologies, especially for the behavioural nature of speaking-up. Nonetheless, safety voice appeared unique in terms of the content of the raised message (e.g., limited to safety), the context and person speaking-up, identified antecedents (e.g., hazard-specific antecedents), and methodological challenges (e.g., operationalisation of victimhood). Our proposed safety voice framework provides a novel approach to safety voice that is ecological and indicates interventions for mitigating physical harm.
This study aims to evaluate the agreement in maximum oxygen consumption (V˙O2max) between a running protocol and a ski mountaineering (SKIMO) protocol. Eighteen (eleven males, seven females) ski ...mountaineers (age: 25 ± 3 years) participated in the study. V˙O2max, maximum heart rate (HRmax), and maximum blood lactate concentration (BLAmax) were determined in an incremental uphill running test and an incremental SKIMO-equipment-specific test. V˙O2max did not differ between the SKIMO and uphill running protocols (p = 0.927; mean difference –0.07 ± 3.3 mL/min/kg), nor did HRmax (p = 0.587, mean difference –0.7 ± 5.1 bpm). A significant correlation was found between V˙O2max SKIMO and V˙O2max running (p ≤ 0.001; ICC = 0.862 (95% CI: 0.670−0.946)). The coefficient of variation was 4.4% (95% CI: 3.3−6.5). BLAmax was significantly lower for SKIMO compared to running (12.0 ± 14.1%; p = 0.002). This study demonstrates that V˙O2max determined with a traditional uphill running protocol demonstrates good agreement with an equipment-specific SKIMO protocol.
This report aims to summarise the scientific knowledge around hydration, nutrition, and metabolism at high altitudes and to transfer it into the practical context of extreme altitude alpinism, which, ...as far as we know, has never been considered before in the literature. Maintaining energy balance during alpine expeditions is difficult for several reasons and requires a deep understanding of human physiology and the biological basis for altitude acclimation. However, in these harsh conditions it is difficult to reconcile our current scientific knowledge in sports nutrition or even for mountaineering to high-altitude alpinism: extreme hypoxia, cold, and the logistical difficulties intrinsic to these kinds of expeditions are not considered in the current literature. Requirements for the different stages of an expedition vary dramatically with increasing altitude, so recommendations must differentiate whether the alpinist is at base camp, at high-altitude camps, or attempting the summit. This paper highlights nutritional recommendations regarding prioritising carbohydrates as a source of energy and trying to maintain a protein balance with a practical contextualisation in the extreme altitude environment in the different stages of an alpine expedition. More research is needed regarding specific macro and micronutrient requirements as well as the adequacy of nutritional supplementations at high altitudes.
As the sport of outdoor rock climbing rapidly grows, there is increasing pressure to understand how it can affect communities of organisms in cliff habitats. To that end, we surveyed 32 cliff sites ...in Boulder, Colorado, USA, and assessed the relative roles of human recreation and natural habitat features as drivers of bird diversity and activity. We detected only native avian species during our observations. Whereas avian abundance was not affected by climbing, avian species diversity and community conservation value were higher at low-use climbing formations. Models indicated that climber presence and cliff aspect were important predictors of both avian diversity and avian cliff use within our study area, while long-term climbing use frequency has a smaller, but still negative association with conservation value and cliff use by birds in the area. In contrast, the diversity of species on the cliff itself was not affected by any of our measured factors. To assess additional community dynamics, we surveyed vegetation and arthropods at ten site pairs. Climbing negatively affected lichen communities, but did not significantly affect other vegetation metrics or arthropods. We found no correlations between avian diversity and diversity of either vegetation or arthropods. Avian cliff use rate was positively correlated with arthropod biomass. We conclude that while rock climbing is associated with lower community diversity at cliffs, some common cliff-dwelling birds, arthropods and plants appear to be tolerant of climbing activity. An abiotic factor, cliff aspect strongly affected patterns of both avian diversity and cliff use, suggesting that the negative effects of rock climbing may be mitigated by informed management of cliff habitat that considers multiple site features.
The majority of research dealing with the impacts of the Himalayan climate on human physiology focuses on low air temperature, high wind speed, and low air pressure and oxygen content, potentially ...leading to hypothermia and hypoxia. Only a few studies describe the influence of the weather conditions in the Himalayas on the body’s ability to maintain thermal balance. The aim of the present research is to trace the heat exchange between humans and their surroundings during a typical, 6-day summit attempt of Mount Everest in the spring and winter seasons. Additionally, an emergency night outdoors without tent protection is considered. Daily variation of the heat balance components were calculated by the MENEX_HA model using meteorological data collected at automatic weather stations installed during a National Geographic expedition in 2019–2020. The data represent the hourly values of the measured meteorological parameters. The research shows that in spite of extreme environmental conditions in the sub-summit zone of Mount Everest during the spring weather window, it is possible to keep heat equilibrium of the climbers’ body. This can be achieved by the use of appropriate clothing and by regulating activity level. In winter, extreme environmental conditions in the sub-summit zone make it impossible to maintain heat equilibrium and lead to hypothermia. The emergency night in the sub-peak zone leads to gradual cooling of the body which in winter can cause severe hypothermia of the climber’s body. At altitudes < 7000 m, climbers should consider using clothing that allows variation of insulation and active regulation of their fit around the body.
Understanding how organizations operate in different environments has been at the core of organizational research for decades. Three distinct bodies of literature have emerged, with limited ...cross-pollination among them: routines, heuristics, and improvisation. We add to the existing literature by studying these three types of organizational responses simultaneously via an in-depth longitudinal study of an organization that encountered increasing levels of environmental dynamism. We pay particular attention to explaining how and why routines broke down, prompting the emergence of heuristics or improvisations, as well as when these three responses were used in tandem and when they interacted with each other. Our theoretical model identifies the triggers of heuristics and improvisations and the focal context that led to routines breaking down. We define “focal context” as a constructed temporary reality that encompasses both the objective traits of the environment experienced by the organization at a particular point in time, as well as the subjective perceptions that organizational members had of that reality. We also identify the mechanisms of cognitive search and social convergence that led to the creation of nonroutine responses. Finally, we use our insights to clarify the existing overlaps in the conceptualization of the three organizational responses. Our field study is based on a mountaineering expedition to climb one of the most difficult sides of Mount Everest, the Kangshung face, an archetypical case that is particularly well suited to the development of a new theory in which rich data are required to study the phenomena.
