Eugenio Barba first defined ‘theatre anthropology’ as the study of the human being in an organized performance situation in a lecture in Warsaw in May 1980. The first session of ISTA (International School of Theatre Anthropology) was held in October 1980 and the last to date in 2023. This article gives a personal account of ISTA’s history from its origins, rooted in Eugenio Barba’s interest in Asian classical theatre techniques and the founding of Odin Teatret in Denmark, to the most recent experiences, which include the intercultural production of Anastasis/Resurrection at the 2023 Theatre Olympics in Budapest. It identifies masters of given ISTA sessions and their invaluable contribution to the School’s emphasis on, and understanding of, craft, as well as the distinguishing characteristics and points of change and development of selected ISTAs.
In recent years, a considerable amount of interest has arisen in the topic of existential inertia (henceforth EIT)and its relation to the natural theology of Thomas Aquinas. While contemporary Thomists have engaged with proponents of EIT, strangely enough, no literature has focused on Aquinas’s own response to the objection(s) from an EIT-like position. The intention of this article is to (1) lay out the basic thrust of EIT and then (2) articulate how Aquinas’s own metaphysical commitments dissolve the problems that EIT raises. After formulating an argument based on Aqunias’s own texts and paying attention to the metaphysical commitments it involves, I then level three objections and respond to them.
Valery Galendeyev seemed immortal, so steady was his demeanour, so light his ample frame. We knew that he had had serious Covid early in the pandemic but his habitual warmth and gentle irony belied his health’s decline as he continued to work as if it would never stop. He understood, though, that, sooner rather than later, his growing ill heath, which he discreetly set aside, would stop him.
The longhorn beetle, Cerambyx welensii (Küster) (Coleoptera: Cerambycidae), is considered a critical factor in oak decline in southwestern Iberia, but populations vary over space and time, depending on several ecological factors. Adults feed on ripe fruits and tree exudates, and evidence suggests that feeding could impact fitness in hot, dry summers, especially under climate change. In the present study, we assessed the impact of adult feeding (sugar-fed, water-fed, or unfed) and remating (monandrous versus polyandrous) on female reproductive output. Lifetime fecundity increased with female size in most feeding–remating combinations. Sugar-fed females achieved the highest longevity and fecundity, unfed females the lowest, and water-fed females had intermediate values. The daily fecundity pattern was strongly dependent on female feeding. Longevity and fecundity of once-mated and remated females were similar in both unfed and water-fed groups; however, in sugar-fed females, remating enhanced fecundity and shortened life span. Preoviposition, oviposition, and postoviposition periods were distinctly affected by both diet and remating. Results show that females require sugar to maximise reproductive output and that a water supply may partially mitigate the fitness decline of unfed females. We conclude that female feeding must be considered to explain C. welensii spatio-temporal occupancy–abundance patterns in oak woodlands.
This study analyzed the impact of environmental regulation, specifically the “2+26” regional strategy for air quality improvement, on corporate research and development (R&D) investment in China. We developed a theoretical model based on the argument that R&D investment rises with regulation intensity. Using 2010–2019 data from China's listed companies located in the Beijing-Tianjin-Hebei region and its surrounding areas, we treated the $2+26$ policy as a quasi-natural experiment and adopted a difference-in-differences approach to explore its effect on firm R&D input. A positive association was observed between firm R&D intensity and the $2+26$ strategy's implementation in major polluting industries. Our results provide in-depth insights into the $2+26$ strategy's economic consequences, which are potentially of interest to both scholars and policymakers.
The studies about the negative effect of epiphytes on their phorophytes show contradictory results and are based on limited variables (e.g., shoot survival). On branches of Bursera copallifera, we experimented with the transplantation/removal of Tillandsia recurvata and artificial tussocks, measuring shoot survival, growth, generation of new shoots, and production of inflorescences and fruits. Most single traits did not differ between treatments. The generation of new shoots was lower in the treatments where T. recurvata was present and increased in the branches where it was removed. The lowest shoot survival was in the treatments where T. recurvata was present or was removed. Removing T. recurvata increased plant relative fitness, and it was 43% lower in branches with T. recurvata. Tillandsia recurvata is a structural parasite of B. copallifera. A negative effect of epiphytes on their phorophytes appears counterintuitive since it would not be evolutionarily stable for an epiphyte to shorten the lifespan of its support. Tillandsia recurvata populations are concentrated on B. copallifera branches between 2-4 cm in diameter, while smaller branches are mostly empty, so it is possible that the negative effect of T. recurvata occurs in the smallest branches, explaining why T. recurvata populations are biased to larger branches.
The usage areas of rotary or fixed wing unmanned aerial vehicles (UAV) have become very widespread with technological developments. For this reason, UAV designs differ in terms of aerodynamic design, flight performance and endurance depending on the intended use. In this study, maximising of the autonomous flight performance of the unmanned helicopter produced at Erciyes University using an optimisation algorithm is discussed. For this purpose, the input parameters of the dynamic model are chosen as blade length, blade mass density, blade chord width and blade twist angle of the unmanned helicopter and the proportional, integral, derivative gain coefficients of the lateral axis of the autopilot. The output parameters of the dynamic model are selected as settling time, rise time and maximum overshoot, which are autonomous performance parameters. The dynamic model consisting of helicopter and autopilot parameters is integrated into the back-tracking search optimisation (BSO) algorithm as an objective function. In the optimization process, where mean squared error (MSE) is used as the performance criterion, optimum input and output values were determined. Thus, helicopter and autopilot parameters, which are among the factors affecting autonomous performance, are taken into account with equal importance and simultaneously. Simulations show that the obtained values are satisfactory. With this approach based on the optimisation method, complex and time-consuming dynamic model calculations are reduced, time and cost are saved, and practicality is achieved in applications. Therefore, this approach can be an innovative and alternative method to improve UAV designs and increase flight performance compared to classical methods.
Seven species of Polydrusus Germar weevils (Coleoptera: Curculionidae) occur in the United States of America and Canada, three of which are introduced from Europe, are polyphagous, and may be displacing native weevil fauna in select areas of North America. We review host plant information for these species and provide distributional maps for each. We also present results on the seasonal phenology and sex ratios of two nonnative species, Polydrusus impressifrons (Gyllenhal) and Polydrusus formosus (Mayer), recorded in 2020 and 2021 in two orchards of hybrid hazelnuts (Betulaceae) in Minnesota, United States of America. These two species may present an episodic threat to the burgeoning hybrid hazelnut industry due to their ability to damage buds, foliage, and roots of hardwoods. We found that adults of these two species began emerging in late May of each year and remained present until mid-July. We found higher numbers of P. formosus than of P. impressifrons on hazel plants. Sex ratios of both species were generally between 50–60% male. We supply a compendium of species descriptions that (1) distinguishes between native and nonnative species and (2) identifies the sex of nonnative species. This research contributes to work on the ecology of Polydrusus, conservation of native species, and the management of tree crops.
Inflammation is involved in the pathogenesis of stroke and depression. We aimed to investigate the association between the dietary inflammatory index (DII) and depression in American adults with stroke. Adults with stroke were enrolled in the National Health and Nutrition Examination Survey between 2005 and 2018 in the USA. The DII was obtained from a 24-h dietary recall interview for each individual. Multivariate regression and restricted cubic spline analyses were conducted to evaluate the association between DII and depression in adults with stroke. The mean age of the 1239 participants was 63·85 years (50·20 % women), and the prevalence of depression was 18·26 %. DII showed a linear and positive association with severe depression in adults with stroke (OR 1·359; 95 % CI 1·021, 1·810; P for non-linearity = 0·493). Compared with those in the lowest tertile of the DII, adults with stroke in the third tertile of the DII had a 3·222-fold higher risk of severe depression (OR 3·222; 95 % CI 1·150, 9·026). In the stratified analyses, the association between DII score and severe depression was more significant in older adults (P for interaction = 0·010) but NS with respect to sex (P for interaction = 0·184) or smoking status (P for interaction = 0·396). No significant association was found between DII and moderate-to-moderately severe depression in adults with stroke. In conclusion, an increase in DII score was associated with a higher likelihood of severe depression in older adults with stroke.
During the past five years the cultural world in Germany has been shaken and divided by a series of controversies involving contemporary works of art charged with being anti-Semitic. Obviously, with the Holocaust continuing to occupy a major position in modern German consciousness and history, sensitivity to anti-Semitic expressions is particularly keen here. This sensitivity has been increased by a number of recent developments, including the growing visibility of far-right political groups, the rise of the Boycott, Divestment, and Sanctions movement (BDS) protesting Israeli treatment of the Palestinians, and the official politicization of these tensions by a parliamentary ruling in 2015 restricting the activities of the BDS. The conflict between legitimate criticism of policies of the Israeli state and legitimate censorship of ethnically offensive material has recently become increasingly bitter in Germany. This article discusses the dynamics of three of the most significant recent examples: the conflict involving Germany’s most prestigious arts festival, the Kassell documenta in 2020; the withdrawal in 2022 of the European Drama Award, the continent’s largest award, from British dramatist Caryl Churchill; and the withdrawal from the Munich stage of the most recent play by Wajdi Mouawad, who has been widely heralded in Germany as the most significant contemporary dramatist.
A previously developed method for large-eddy simulations (LES), based on spectral eddy-viscosity models, is generalised to the physical space representation. The method estimates the subgrid-scale (SGS) energy transfer using a similarity-type model expression for the SGS tensor obtained using Gaussian filtering of velocity fields advanced in the simulations. Following steps for the spectral space representation, the SGS transfer in the physical space is used to obtain a spatially varying eddy viscosity at each time step in LES. The computed eddy viscosity is employed to model the SGS stress tensor in the familiar Boussinesq form for use in LES. The method is tested in LES of isotropic turbulence at high Reynolds numbers where the inertial range dynamics is expected and for lower Reynolds number decaying turbulence under conditions of the classical Comte-Bellot and Corrsin experiments. In both cases the agreement with reference data is very good and the SGS transfer computed for the proposed eddy-viscosity model is highly correlated with the transfer computed for the similarity-type stress tensor.
Climate disasters raise the salience of climate change’s negative consequences, including climate-induced migration. Policy action to address climate displacement is especially contentious in the United States, where weak support for tackling climate change intersects with high opposition to migration. Do climate disasters foster receptivity toward climate migrants and broader willingness to combat climate change? To study this question, we leverage the occurrence of Hurricane Ian during fielding of a preregistered survey in autumn 2022. Hurricane exposure increased concern about and support for policies to address climate migration. Hurricane exposure also increased support for climate action and belief in anthropogenic climate change. Effects of hurricane exposure cross-cut partisanship, education, age, and other important correlates of climate attitudes but decay within 6 months. Together, these results suggest that climate disasters may briefly increase favorability toward climate migrants and climate policy action but are unlikely to durably mobilize support even in severely impacted areas.
Visual representations of aging have historically relied upon binarized clichés: idealized youthfulness versus frailty and illness. To challenge these oversimplified depictions, graduate students developed a community outreach project titled ‘Seniors of Canada’. The aim of this project was twofold: (1) share images and stories of people in later life; and (2) challenge dominant narratives and stereotypes of aging. In this note, we outline the prevailing discourse of what aging ‘looks like’, how we collected stories and images, and implications for knowledge mobilization and research in Canada. This article highlights insights gained since the inception of the project, including three key learnings: (1) Building bridges across academia and community, (2) Intergenerational connection and digital tools, and (3) The power of visual storytelling. We provide a practical overview of a successful knowledge mobilization/community outreach project and showcase the power of bridging academia and community for social change.
Microvibrations originating from onboard disturbance sources can lead to a range of issues, including a decrease in satellite pointing accuracy, image distortion and blurring. Therefore, reaction wheels emerge as the primary sources of disturbance noise. This paper employs an experimental approach based on the real dynamics of rotating reaction wheel assembly, closely simulating on-orbit configurations to measure noise responses transferred to the satellite structure. An assessment of noise response behaviour, incorporating a comprehensive understanding of the factors influencing the levels, was conducted on a proto-flight satellite for three reaction wheels. Initially, reaction wheel assemblies underwent individual iterative balancing to reduce mass deviations. Subsequently, amplitude-time responses at different rotational speeds of reaction wheel assemblies (RWA) disturbance noise were measured. The experimental results demonstrate that each individually balanced reaction wheel generates independent perturbation noise level due to manufacturing imperfections. Hence, the necessity of wheels testing for accurate prediction and mitigation of disturbance levels is crucial, especially for payloads sensitive to microvibrations. Furthermore, increasing wheel speeds proportionally amplify disturbance noise levels. Therefore, implementing an optimised mission attitude control profile with lower rotation speeds of reaction wheels effectively reduces microvibration levels which minimises risks to payload performance and reduce power consumption.
Cognitive models of mental contamination (i.e. feelings of internal dirtiness without contact with a contaminant) propose that these feelings arise when individuals misappraise a violation. However, an operational definition of ‘violation’ and identification of specific violation misappraisals is limited.
Aims:
This study’s aim was to elaborate on cognitive models using qualitative data from those with lived experience to fill these gaps.
Method:
Twenty participants with a diagnosis of obsessive-compulsive disorder and/or a trauma history took part in a semi-structured interview about violation. Grounded theory was used to analyse interview transcripts.
Discussion:
Three categories emerged, each with several themes – qualities of violation, violation-related appraisals, and violation-related behaviours. Different violation-related appraisals were associated with different emotions and urges. Specific self-focused appraisal sub-themes (i.e. permanence of consequences; self-worth; responsibility, self-blame and regret) were most closely related to emotions tied to mental contamination. These findings support and expand upon existing cognitive models of mental contamination, identifying key violation-related appraisals and differentiating between mental contamination-related appraisals and those related to other emotional sequelae. Future quantitative and experimental research can evaluate the potential of these appraisals as intervention targets.
