History of Avalanches in the Eastern Spanish Pyrenees.

Avalanches have caused injuries and deaths in mountain areas throughout history. We have examined the historical effects of avalanches on communities in the eastern Spanish Pyrenees. Surviving written records began in the year 1444 when an avalanche destroyed the village of Gessa. Many other avalanches since then have destroyed houses and other buildings and have caused injuries and deaths. In the 20th and 21st centuries, many villages evolved from agrarian areas to destinations for winter sports. The first known deaths during winter recreation likely occurred in 1930. Because of avalanche mitigation efforts, including relocating settlements, physical barriers, avalanche control measures, efforts to increase avalanche awareness, and avalanche warnings, avalanches now seldom affect inhabited areas in the eastern Spanish Pyrenees. Avalanche injuries and fatalities are now mainly limited to backcountry skiers and others traveling out of bounds near avalanche-controlled ski resorts.

Isolated Ptosis Following a Vipera aspis Bite.

In Spain, snakebites are uncommon medical emergencies that cause barely 100 hospitalizations annually. Most of the venomous bites are by snakes of the Viperidae family. Venom from Vipera snakes is reported to have cytotoxic and hematotoxic effects, and neurological effects have also been described. Ptosis (cranial nerve III palsy) is the most common sign, although any cranial nerve can be affected. We describe isolated ptosis, which was very likely after a Vipera aspis bite in the East Catalonian Pyrenees. No antivenom was administered. The ptosis resolved spontaneously within 10 h. Although neurologic findings are usually mild, they indicate a moderate or severe envenomation. Treating snakebites can be challenging for clinicians, especially when there are uncommon clinical manifestations. A toxicologist at a poison center should be consulted to help guide management. Development of local protocols may provide clinical support.

ArchABM: An agent-based simulator of human interaction with the built environment. CO2 and viral load analysis for indoor air quality.

Recent evidence suggests that SARS-CoV-2, which is the virus causing a global pandemic in 2020, is predominantly transmitted via airborne aerosols in indoor environments. This calls for novel strategies when assessing and controlling a building's indoor air quality (IAQ). IAQ can generally be controlled by ventilation and/or policies to regulate human-building-interaction. However, in a building, occupants use rooms in different ways, and it may not be obvious which measure or combination of measures leads to a cost- and energy-effective solution ensuring good IAQ across the entire building. Therefore, in this article, we introduce a novel agent-based simulator, ArchABM, designed to assist in creating new or adapt existing buildings by estimating adequate room sizes, ventilation parameters and testing the effect of policies while taking into account IAQ as a result of complex human-building interaction patterns. A recently published aerosol model was adapted to calculate time-dependent carbon dioxide (CO2) and virus quanta concentrations in each room and inhaled CO2 and virus quanta for each occupant over a day as a measure of physiological response. ArchABM is flexible regarding the aerosol model and the building layout due to its modular architecture, which allows implementing further models, any number and size of rooms, agents, and actions reflecting human-building interaction patterns. We present a use case based on a real floor plan and working schedules adopted in our research center. This study demonstrates how advanced simulation tools can contribute to improving IAQ across a building, thereby ensuring a healthy indoor environment.

The role of prison officers' regulation of inmates affect on their exposure to violent behaviours and the development of PTSD symptoms.

Background: Interactions with inmates are a major source of stress for prison officers. Given the conflicting nature of this relationship, violent behaviours towards prison officers are not uncommon, posing a threat to their psychological well-being. Objective: This study analyses the role that the strategies prison officers use to regulate inmates' emotions have on the frequency of inmates' violent behaviour and on the presence of posttraumatic stress symptoms in prison officers. Based on interactional models of emotional regulation, a model is proposed in which interpersonal regulation has an indirect effect on PTSD symptoms mediated by the response of the inmate. Method: A total of 424 prison officers employed at 5 Uruguayan prisons completed a questionnaire. Results: The results confirm that emotional regulation strategies are related to inmates' violent behaviour, which in turn affects prison officers' PTSD symptoms. In particular, prison officers use of strategies to improve inmates' affect reduces the level of inmate´s violent behaviours that mediate the negative relationship between affect-improving strategies and officers' PTSD symptoms. The mediating role of inmates' violent behaviour is also confirmed for the positive relationship between affect-worsening strategies and PTSD symptoms. Unexpected results for affect-worsening strategies suggest the presence of a conflict escalation cycle. Conclusion: The impact of the interpersonal regulation of the affect of inmates on the quality of prison officer-inmate relationships and on the exposure of prison officers to potentially traumatic violent events must be taken into account in the analysis of PTSD symptom development. The practical implications for the reduction of the exposure to potentially traumatic violent events and the prevention of PTSD symptoms among prison officers are discussed.

Antecedentes: Las interacciones con los reclusos son una fuente importante de estrés para los oficiales de prisiones. Dada la naturaleza conflictiva de esta relación, las conductas violentas contra los oficiales de prisiones no son infrecuentes, constituyendo un riesgo a su bienestar psicológico.Objetivo: Este estudio analiza el rol que desempeñan las estrategias empleadas por los oficiales de prisiones para regular las emociones de los reclusos sobre la frecuencia de la conducta violenta de los reclusos y sobre la presencia de síntomas de trastorno de estrés postraumático (TEPT) en oficiales de prisiones. Basados en modelos de interacción de regulación emocional, se propone un modelo en el cual la regulación interpersonal tiene un efecto indirecto sobre los síntomas de TEPT mediados por las respuestas de los reclusos.Métodos: Un total de 424 oficiales de prisiones trabajadores de cinco prisiones uruguayas completaron un cuestionario.Resultados: Los resultados confirman que las estrategias de regulación emocional están relacionadas con la conducta violenta de los reclusos, lo cual, a su vez, afecta los síntomas de TEPT de los oficiales de prisiones. En particular, el uso de estrategias para mejorar el afecto de los reclusos por parte de los oficiales de las prisiones reduce el nivel de la conducta violenta de los reclusos que median la relación negativa entre las estrategias para mejorar el afecto y los síntomas de TEPT en los oficiales. El rol mediador del comportamiento violento de los reclusos también fue confirmado por la relación positiva entre las estrategias que empeoran los afectos y los síntomas de TEPT. Los resultados inesperados de estrategias que pueden empeorar el afecto sugieren la presencia de un ciclo de intensificación de conflictos.Conclusión: El impacto de la regulación interpersonal del afecto de los reclusos sobre la calidad de las relaciones entre ellos y los oficiales de prisiones, y sobre la exposición de los oficiales a eventos violentos potencialmente traumáticos deben ser considerados en el análisis del desarrollo de los síntomas de TEPT. Se discuten las implicaciones prácticas para la reducción de la exposición a eventos violentos potencialmente traumáticos y la prevención de los síntomas de TEPT en los oficiales de prisiones.

Home range size in central chimpanzees (Pan troglodytes troglodytes) from Loango National Park, Gabon.

Ranging behavior has been studied extensively in eastern (Pan troglodytes schweinfurthii) and western (P. t. verus) chimpanzees, but relatively little is known regarding home ranges of the other two subspecies (P. t. ellioti; P. t. troglodytes). In this study, we determined the home range size and space use of a habituated community (Rekambo) of central chimpanzees living in a habitat mosaic in Loango National Park, Gabon. Data on travel routes were collected during follows between January 2017 and April 2019 (N = 670,616 relocations, collected over 640 days and 5690 h of observation). We used three methods for calculating home range size (minimum convex polygon, kernel density estimation, and biased random bridges). We compare our estimates to those obtained from prior genetic and camera trap studies of the Rekambo community and contrast them with estimates from other chimpanzee communities of the four chimpanzee subspecies. Depending on the methodology used, the home range size of the Rekambo community ranged between 27.64 and 59.03 km2. The location of the center of the home range remained relatively stable over the last decade, while the overall size decreased. The Rekambo home range is, therefore, one of the largest documented so far for chimpanzees outside savannah-woodland habitats. We discuss several explanations, including the presence of savannah, interspecies competition, and intercommunity interactions.

Validation of an Attributional and Distributive Justice Mediational Model on the Effects of Surface Acting on Emotional Exhaustion: An Experimental Study.

Previous research has shown that surface acting-displaying an emotion that is dissonant with inner feelings-negatively impacts employees' well-being. However, most studies have neglected the meaning that employees develop around emotional demands requiring surface acting. This study examined how employees' responsibility attributions of client behavior demanding surface acting influence employees' emotional exhaustion, and the mediational role of distributive justice in this relationship. Relying on Fairness Theory, it was expected that employees' responsibility attributions of client behavior demanding emotion regulation would be related to their perceptions of distributive injustice during the service encounter, which in turn would mediate the effects of responsibility attribution on emotional exhaustion. In addition, drawing on the conservation of resources model, we contended that leader support would moderate the impact of distributive injustice on emotional exhaustion. Two scenario-based experiments were conducted. Study 1 (N = 187) manipulated the attribution of responsibility for emotional demands. The findings showed that distributive injustice and emotional exhaustion were higher when responsibility for the surface acting demands was attributed to the client. A bootstrapping mediational analysis confirmed employees' attributions have an indirect effect on emotional exhaustion through distributive justice. Study 2 (N = 227) manipulated responsibility attribution and leader support. The leader support moderation effect was confirmed.

Intercommunity interactions and killings in central chimpanzees (Pan troglodytes troglodytes) from Loango National Park, Gabon.

Intercommunity competition in chimpanzees (Pan troglodytes) has been widely studied in eastern (P. t. schweinfurthii) and western (P. t. verus) communities. Both subspecies show hostility towards neighboring communities but differ in rates of lethal attacks and female involvement. However, relatively little is known about the territorial behavior of the two other subspecies, central (P. t. troglodytes) and Nigeria-Cameroon chimpanzees (P. t. ellioti). Here, we present the first insights into intercommunity interactions of individuals of a community of central chimpanzees living in the Loango National Park in Gabon. The presence of individuals of neighboring communities in the Rekambo home range was assessed using 27 camera traps. Information was compiled on intergroup interactions recorded before (2005-2016) and after (January 2017-June 2019) the habituation of the community. Individuals from neighboring communities entered the core area, where nine out of 16 recorded intercommunity encounters occurred. Males were the main participants in territorial patrols and intercommunity aggressions. Females were part of all six territorial patrols recorded and dependent offspring participated in five patrols. Females were involved in intercommunity aggression in five out of twelve recorded encounters in which there was visual contact between communities. While the intercommunity encounter rate was lower than that reported across most other long-term chimpanzee sites, the annual intercommunity killing rate was among the highest. These results suggest that the frequency of lethal attacks at Loango is comparable to that reported for the eastern subspecies. In contrast, female involvement in intercommunity interactions mirrors that of the western subspecies.

Fear of pain moderates the relationship between self-reported fatigue and methionine allele of catechol-O-methyltransferase gene in patients with fibromyalgia.

Previous research has shown a consistent association among genetic factors, psychological symptoms and pain associated with fibromyalgia. However, how these symptoms interact to moderate genetic factors in fibromyalgia has rarely been studied to date. The present research investigates whether psychological symptoms can moderate the effects of catechol-O-methyltransferase on pain and fatigue. A total of 108 women diagnosed with fibromyalgia and 77 healthy control participants took part in the study. Pain, fatigue, and psychological symptoms (anxiety, depression, pain catastrophizing, fear of pain and fear of movement) were measured by self-report questionnaires. Two types of statistical analyses were performed; the first was undertaken to explore the influences of COMT genotypes on clinical symptoms by comparing patients with fibromyalgia and healthy controls. In the second analysis, moderation analyses to explore the role of psychological symptoms as potential factors that moderate the relationship between pain/fatigue and COMT genotypes were performed. The main results indicated that patients carrying the Met/Met genotype reported significantly higher levels of fatigue than heterozygote carriers (i.e., Met/Val genotype) and higher levels of fatigue, but not significantly different, than Val homozygote carriers. Among patients with fibromyalgia carrying methionine alleles (i.e., Met/Met + Met/Val carriers), only those who scored high on medical fear of pain, experienced an intensified feeling of fatigue. Thus, the present research suggests that fear of pain, as a psychological symptom frequently described in fibromyalgia may act as a moderating factor in the relationship between the Met allele of the COMT gene and the increase or decrease in self-reported fatigue. Although further research with wider patient samples is needed to confirm the present findings, these results point out that the use of psychological interventions focused on affective symptomatology might be a useful tool to reduce the severity of fibromyalgia.
