Введение. Формирование дефинитивной длины тела определяется генетическими факторами и факторами окружающей среды. Актуальной задачей является межсистемный анализ связей секулярной динамики длины тела с изменениями во времени социально-экономических и демографических показателей. Подобная модель взаимосвязей была разработана для изменений длины тела населения России во второй половине XX в. на основе флуктуаций во времени социально-экономических и демографических показателей. Цель данной работы – проверка работоспособности общероссийской модели на региональных материалах – анализ общих тенденций и выявление особенностей на примере четырех крупных городов России. Материалы и методы. Материалами послужили временные ряды антропометрических, социально-экономических и демографических показателей из открытых источников. Использованы данные по длине тела, собранные авторами в 2020-2024 гг. в результате обследования молодежи 17-23 лет в четырех городах России: Барнаул, Москва, Петрозаводск и Краснодар. Длина тела для демографических когорт с 1930-39 гг. до начала 2000-х гг. рождения получена из источников литературы. Результаты и обсуждение. Показано, что изменчивость длины тела в отдельных городах и федеральных округах сходна с общероссийской. В первой половине XX в. наблюдается резкое увеличение дефинитивной длины тела с последующим снижением прироста и выходом на плато. Для современной когорты обследованных (2000-2006 гг. рождения) в некоторых крупных городах отмечено уменьшение длины тела. Заключение. Проверка регрессионной модели общероссийского секулярного тренда длины тела в связи с изменениями во времени социально-экономических и демографических показателей на региональных данных показала близкие результаты. Выявленные региональные особенности могут быть обусловлены разновременной динамикой изменений социально-экономических условий. Незначительное уменьшение длины тела в некоторых городах России у молодежи 2000-2006 гг. рождения может свидетельствовать об изменении направления секулярного тренда, что подтверждает общебиологическую гипотезу о волнообразном характере трансэпохальной динамики дефинитивной длины тела. Финансирование. Работа выполнена при поддержке гранта РНФ № 23-18-00086 «Региональные особенности влияния социально-экономических и социокультурных факторов на секулярный тренд размеров тела современной молодёжи на рубеже XX-XXI веков».

Understanding species distributions is a global priority for mitigating environmental pressures from human activities. Ample studies have identified key environmental (climate and habitat) predictors and the spatial scales at which they influence species distributions. However, regarding human influence, such understandings are largely lacking. Here, to advance knowledge concerning human influence on species distributions, we systematically reviewed species distribution modelling (SDM) articles and assessed current modelling efforts. We searched 12,854 articles and found only 1,429 articles using human predictors within SDMs. Collectively, these studies of >58,000 species used 2,307 unique human predictors, suggesting that in contrast to environmental predictors, there is no ‘rule of thumb’ for human predictor selection in SDMs. The number of human predictors used across studies also varied (usually one to four per study). Moreover, nearly half the articles projecting to future climates held human predictors constant over time, risking false optimism about the effects of human activities compared with climate change. Advances in using human predictors in SDMs are paramount for accurately informing and advancing policy, conservation, management and ecology. We show considerable gaps in including human predictors to understand current and future species distributions in the Anthropocene, opening opportunities for new inquiries. We pose 15 questions to advance ecological theory, methods and real-world applications. A systematic review of 12,854 articles that use species distribution modelling shows that only 1,429 include human predictors as well as environmental ones. Half of those that include human predictors alongside future climate projections keep the human factors constant over time. The article discusses the need for greater inclusion of human predictors to inform policy and management.

This late-breaking work presents a large-scale analysis of explainable AI (XAI) literature to evaluate claims of human explainability. We collaborated with a professional librarian to identify 18,254 papers containing keywords related to explainability and interpretability. Of these, we find that only 253 papers included terms suggesting human involvement in evaluating an XAI technique, and just 128 of those conducted some form of a human study. In other words, fewer than 1% of XAI papers (0.7%) provide empirical evidence of human explainability when compared to the broader body of XAI literature. Our findings underscore a critical gap between claims of human explainability and evidence-based validation, raising concerns about the rigor of XAI research. We call for increased emphasis on human evaluations in XAI studies and provide our literature search methodology to enable both reproducibility and further investigation into this widespread issue.

In this short paper we address issues related to building multimodal AI systems for human performance support in manufacturing domains. We make two contributions: we first identify challenges of participatory design and training of such systems, and secondly, to address such challenges, we propose the ACE paradigm: "Action and Control via Explanations". Specifically, we suggest that LLMs can be used to produce explanations in the form of human interpretable "semantic frames", which in turn enable end users to provide data the AI system needs to align its multimodal models and representations, including computer vision, automatic speech recognition, and document inputs. ACE, by using LLMs to "explain" using semantic frames, will help the human and the AI system to collaborate, together building a more accurate model of humans activities and behaviors, and ultimately more accurate predictive outputs for better task support, and better outcomes for human users performing manual tasks.

Human activities are reducing the amount and quality of natural landscapes. Understanding how such changes affect the spatial and temporal ecology of mammal populations will enable us to foresee how communities will be structured in the Anthropocene. Here, we evaluated how the occupancy, intensity of use, and activity patterns of the mesopredator canid Cerdocyon thous are affected by topographic variation, habitat amount, fragmentation and chronic anthropogenic disturbances. Camera trapping data were obtained between May and September 2014 in 179 sampling points within ten priority areas for conservation in a seasonally dry tropical forest (Caatinga) in Brazil, totaling an effort of 6,701 camera.days. We use occupancy models for analyzed occupancy, generalized linear models (GLM) for the intensity of use and kernel density curve for activity pattern. Cerdoyon thous benefited from human disturbance, showing greater occupancy and intensity of use near anthropogenic habitats, fragmentation, human density and cattle density. Moreover, temporal analyses showed that it modulates its daily activity according to habitat amount, human density, cattle density and altitude. However, C. thous tends to avoid areas with excess of fire, logging and infrastructures. These results allow us to understand the mechanisms that contribute to the dominance of generalist mesocarnivores in human-dominated environments.

Background Efficient movement and energy expenditure are vital for animal survival. Human disturbance can alter animal movement due to changes in resource availability and threats. Some animals can exploit anthropogenic disturbances for more efficient movement, while others face restricted or inefficient movement due to fragmentation of high-resource habitats, and risks associated with disturbed habitats. Mining, a major anthropogenic disturbance, removes natural habitats, introduces new landscape features, and alters resource distribution in the landscape. This study investigates the effect of mining on the movement of an endangered mesopredator, the northern quoll ( Dasyurus hallucatus ). Using GPS collars and accelerometers, we investigate their habitat selection and energy expenditure in an active mining landscape, to determine the effects of this disturbance on northern quolls. Methods We fit northern quolls with GPS collars and accelerometers during breeding and non-breeding season at an active mine site in the Pilbara region of Western Australia. We investigated broad-scale movement by calculating the movement ranges of quolls using utilisation distributions at the 95% isopleth, and compared habitat types and environmental characteristics within observed movement ranges to the available landscape. We investigated fine-scale movement by quolls with integrated step selection functions, assessing the relative selection strength for each habitat covariate. Finally, we used piecewise structural equation modelling to analyse the influence of each habitat covariate on northern quoll energy expenditure. Results At the broad scale, northern quolls predominantly used rugged, rocky habitats, and used mining habitats in proportion to their availability. However, at the fine scale, habitat use varied between breeding and non-breeding seasons. During the breeding season, quolls notably avoided mining habitats, whereas in the non-breeding season, they frequented mining habitats equally to rocky and riparian habitats, albeit at a higher energetic cost. Conclusion Mining impacts northern quolls by fragmenting favoured rocky habitats, increasing energy expenditure, and potentially impacting breeding dispersal. While mining habitats might offer limited resource opportunities in the non-breeding season, conservation efforts during active mining, including the creation of movement corridors and progressive habitat restoration would likely be useful. However, prioritising the preservation of natural rocky and riparian habitats in mining landscapes is vital for northern quoll conservation.

Humans are perceived as predators by many species and may generate landscapes of fear, influencing spatiotemporal activity of wildlife. Additionally, wildlife might seek out human activity when faced with predation risks (human shield hypothesis). We used the anthropause, a decrease in human activity resulting from the COVID-19 pandemic, to test ecology of fear and human shield hypotheses and quantify the effects of bear-viewing ecotourism on grizzly bear (Ursus arctos) activity. We deployed camera traps in the Khutze watershed in Kitasoo Xai'xais Territory in the absence of humans in 2020 and with experimental treatments of variable human activity when ecotourism resumed in 2021. Daily bear detection rates decreased with more people present and increased with days since people were present. Human activity was also associated with more bear detections at forested sheltered sites and less at exposed sites, likely due to the influence of habitat on bear perception of safety. The number of people negatively influenced adult male detection rates, but we found no influence on female with young detections, providing no evidence that females responded behaviorally to a human shield effect from reduced male activity. We also observed apparent trade-offs of risk avoidance and foraging. When salmon levels were moderate to high, detected bears were more likely to be females with young than adult males on days with more people present. Should managers want to minimize human impacts on bear activity and maintain baseline age-sex class composition at ecotourism sites, multiday closures and daily occupancy limits may be effective. More broadly, this work revealed that antipredator responses can vary with intensity of risk cues, habitat structure, and forage trade-offs and manifest as altered age-sex class composition of individuals using human-influenced areas, highlighting that wildlife avoid people across multiple spatiotemporal scales.

The approximately 320 atolls of the world, scattered across the tropical oceanic basins, constitute a unique type of ecosystem in that they are each an integrated unit consisting of island, coral reef, and lagoon components. Atolls have a complex geology, ecology, and biogeography, which can be fully appreciated only by transcending the classic boundary thinking of marine and terrestrial realms. The atolls we observe today were shaped by Quaternary sea-level fluctuations, which imposed strong environmental filters on their communities. As entirely biogenic, reef-borne structures, the islands of atolls depend upon marine productivity, which catalyzes island community assembly. Island species communities exist in complex dynamic equilibria with the surrounding oceanographic conditions. Energy fluxes and element cycles of the atoll system readily cross habitat boundaries and create a productive, diverse, and biomass-rich ecosystem on land and underwater. Past human disturbances and future global change put atolls at the forefront of conservation and ecological restoration.

Abstract Colonial nesting waterbirds in agricultural landscapes have historically received limited research attention, especially in South Asia. For example, the Asian openbill (Anastomus oscitans) is a colonial species that extensively utilizes agricultural landscapes, yet there is a notable lack of substantial studies despite increasing urbanization across these landscapes. We investigated the factors affecting the breeding ecology of Asian openbills in eastern Nepal. We used a grid‐based approach to locate stork colonies and monitored them throughout the breeding season from May to November for three consecutive years (2020–2022). Altogether, we observed a total of 67 active colonies, comprising 4020 active nests, which successfully fledged a total of 7566 chicks. Additionally, most of the colonies were located within areas of human settlements (40%), followed by community forests (33%) and agricultural land (27%). The Asian openbills primarily preferred large trees, such as Bombax ceiba (72%), for nesting. The mean height of nesting trees was approximately 4 m taller, the diameter at breast height was twice as large, and the canopy cover area was three times greater than that of non‐nesting trees. The canopy cover area of trees positively influenced the colony size, while colony size positively influenced the fledgling's success. Our study underscores the significance of large trees in providing sufficient space for accommodating a substantial number of openbill nests and fledglings. These findings have significant implications for conservation efforts to protect large trees along with wetlands and agricultural lands, as crucial measures to ensure the sustainable breeding of this nationally vulnerable species.

Urbanization has resulted in changes in bird life histories, and some species have successfully adapted to urban environments, resulting in synurbization. Nest site selection in urban areas challenges cavity nesters because natural nest sites are often replaced by artificial holes. This study was conducted to identify the nest site selection and nest characteristics of the Eurasian tree sparrow (Passer montanus) living in an urban environment. This species inhabits artificial structures and tree holes around human settlements. We surveyed nests of tree sparrows on the Chonnam National University campus, located in Gwangju, Republic of Korea, during the first clutch from March to May 2020. We categorized nest types into natural and artificial nest sites. The tree sparrows selected natural nest sites such as woodpecker's holes and cracks in trees, and selected artificial nest sites which included holes in concrete buildings, under roofs, and in steel frames and nesting boxes. No significant differences were found in breeding schedules and reproductive success between birds nesting in artificial and natural holes. The results suggest that tree sparrows can successfully adapt to an urban environment by selecting nest sites regardless of nest hole type, and can reproduce successfully when nesting in both natural and artificial holes.

The introduction of information and communication technology (ICT) has altered the way society operates things. ICT is used in various sectors, including agriculture. It can be used in the agricultural sector to distribute pricing and encourage agricultural commodity exports. The study aims to investigate the effect of ICT on cashew nut export in Benin using an autoregressive distributed lag (ARDL) approach. Data were collected over the period of 31 years (1990–2020) in Benin. The estimated results showed that mobile cellular telephone subscription is negatively and significantly correlated with cashew nut export in the short-run. However, in the long-run, it exhibits a positive and significant correlation. On the other hand, internet usage had no significant effect on cashew nut export in the short-run, but negatively influenced cashew nut export in the long-run. These results suggest that to increase its cashew nut export, the Beninese government should invest in technological infrastructure to improve internet access by reducing the cost of internet and increasing education that will allow farmers to better understand and use ICT.

A Festa de Santos Reis, uma manifestação da cultura caipira e do catolicismo popular, é realizada anualmente no município de Juquitiba-SP, no bairro rural dos Camargos. A partir dos conceitos de território e de territorialidade, busca-se compreender e refletir sobre a permanência de elementos da cultura caipira, tal como a Festa de Santos Reis, diante do avanço do processo de urbanização. O trabalho de campo para o registro de relatos orais de seus moradores, bem como a obtenção de demais informações durante a festividade, foi fundamental para a realização da pesquisa. É possível considerar, com a investigação, que apesar de a expansão urbana ter incidido sobre os modos de vida tradicionais, as diferentes apropriações do espaço se refletem na formação de territórios simbólicos que sustentam práticas da cultura caipira, tal como a Festa de Santos Reis, o que lhe confere o caráter de resistência.

The relationship between oil price movements and stock markets during the COVID-19 pandemic and the geopolitical crisis like the ongoing Russian-Ukraine war is yet unexplored extensively. This study therefore examines the return-correlation effects of oil prices on stock markets and their spillover effects in oil-exporting and European countries using daily closing data. After estimating the GARCH process, we employ the static and dynamic Markov Switching model that allow the relationship between oil price and stock market to switch between two regimes coined the COVID-19 and the Russia-Ukraine war periods. The static model shows stock price returns to respond positively and significantly to oil price returns in Italy, Germany and the US during the Covid-19 period while the response is significantly positive only for US in the Russia-Ukraine war period. As regards the volatility spillover, significant spillover is found from stock to oil market for Nigeria, vice versa for Saudi Arabia and bi-directional volatility spillover found for the US, Italy and Germany during the COVID-19 period. The policy implication is that Nigeria and Saudi Arabia should prioritize financial policy and energy policy respectively while US, Italy and Germany should adopt policy coordination to stabilize oil-stock market volatility during low oil price period like the COVID-19 period.

Humanity-centered design is a concept of emerging interest in HCI, one motivated by the limitations of human-centered design. As discussed to date, humanity-centered design is compatible with but goes beyond human-centered design in that it considers entire ecosystems and populations over the long term and centers participatory design. Though the intentions of humanity-centered design are laudable, current articulations of humanity-centered design are incoherent in a number of ways, leading to questions of how exactly it can or should be implemented. In this article, I delineate four ways in which humanity-centered design is incoherent, which can be boiled down to a tendency toward hubris, and propose a more fruitful way forward, a humble approach to humanity-centered design. Rather than a contradiction in terms, "humility" here refers to an organic, piecemeal, patterns-based approach to design that will be good for our being on this earth.

Steering models (such as the generalized two-point model) predict human steering behavior well when the human is in direct control of a vehicle. In vehicles under autonomous control, human control inputs are not used; rather, an autonomous controller applies steering and acceleration commands to the vehicle. For example, human steering input may be used for state estimation rather than direct control. We show that human steering behavior changes when the human no longer directly controls the vehicle and the two are instead working in a shared autonomy paradigm. Thus, when a vehicle is not under direct human control, steering models like the generalized two-point model do not predict human steering behavior. We also show that the error between predicted human steering behavior and actual human steering behavior reflects a fundamental difference when the human directly controls the vehicle compared to when the vehicle is autonomously controlled. Moreover, we show that a single distribution describes the error between predicted human steering behavior and actual human steering behavior when the human's steering inputs are used for state estimation and the vehicle is autonomously controlled, indicating there may be a underlying model for human steering behavior under this type of shared autonomous control. Future work includes determining this shared autonomous human steering model and demonstrating its performance.

Bimanual handovers are crucial for transferring large, deformable or delicate objects. This paper proposes a framework for generating kinematically constrained human-like bimanual robot motions to ensure seamless and natural robot-to-human object handovers. We use a Hidden Semi-Markov Model (HSMM) to reactively generate suitable response trajectories for a robot based on the observed human partner's motion. The trajectories are adapted with task space constraints to ensure accurate handovers. Results from a pilot study show that our approach is perceived as more human--like compared to a baseline Inverse Kinematics approach.

Abstract The bath industry has multiple attributes, such as economic, health, and cultural communication. Therefore, exploring this industry's spatial pattern evolution is crucial to forming a healthy and balanced development model. Based on POI (Points of Interest) and population migration data, this paper uses spatial statistics and radial basis function neural network to explore the spatial pattern evolution and influencing factors of the bath industry in mainland China. The results show that: (1) The bath industry presents a strong development pattern in the north, south-northeast, and east-northwest regions and weak development in the rest of the country. As a result, the spatial development of new bath space is more malleable. (2) The input of bathing culture has a guiding role in developing the bath industry. The growth of market demand and related industries has a specific influence on the development of the bath industry. (3) Improving the bath industry's adaptability, integration, and service level are feasible to ensure healthy and balanced development. (4) Bathhouses should improve their service system and risk management control during the pandemic.
