No full textA storyline approach to select the CMIP6 model ensemble to be downscaled for the South America domain
No full textSelecting the most appropriate Global Climate Models (GCMs) is necessary for Regional Climate Models (RCMs) downscaling. We propose a methodology to select CMIP6 GCMs based on the representation of the multiple physical processes which control regional circulation in a specific domain and the uncertainty in the precipitation projections. To develop the methodology, we identified relevant climate features for the South American (SA) region, focusing on the two most important climatological features: the South American Monsoon System (SAMS) and extratropical cyclones. A set of indicators was defined based on the precipitation in three specific regions (La Plata, the Amazon basins, and Southeastern Brazil) and circulation patterns that are part of the SAMS and control the trajectories of extratropical cyclones (South American Low-Level jets, South Atlantic and South Pacific Subtropical Highs, trade winds, Bolivian High, cyclonic vortices, and upper-level jet stream). The selection of the CMIP6 GCM ensemble is based on historical validation of the circulation patterns and the spread in possible future circulation changes that can lead to different precipitation responses. We used a storyline approach to assess the spread in the precipitation response controlled by regional circulation uncertainty and to identify the wettest and driest possible futures. To assess both SAMS (in summer) and extratropical cyclone patterns (in summer and winter), three storylines were used. The final proposed minimal ensemble comprises four CMIP6 GCMs that correctly represent the main climatological features in SA and are able to cover the uncertainty in the future precipitation response in the three examined regions

No full textAn investigation of the relationship between transformational and transactional leadership, organizational commitment and wellness in policing: a mixed methods approach
No full textPolicing is a stressful profession, and effective leadership is needed to mitigate
the effects of organizational stressors that make it one of the most hazardous
occupations in the world. Evidence suggests that transformational and
transactional leadership can influence the health outcomes and commitment
levels of officers, but much of the research and strategies are derived from large
jurisdictions and have failed to account for smaller resource constrained
contexts. Therefore, the viability of these strategies in smaller jurisdictions such
as those in the Caribbean are understudied. Studies have tended to apply
quantitative methodologies, which do not give officers a voice to fully capture
their contextual experiences that ultimately shape their work related outcomes.
To address this gap, more context specific research is needed which captures the
voice of officers and investigates how leadership directly impacts organizational
commitment and wellness in smaller jurisdictions. These insights will be critical
in developing leadership strategies that are more inclusive, culturally relevant
and effective in Caribbean policing.
Using an explanatory mixed methods design, survey data were gathered from
269 police officers through a web-based questionnaire that comprised items
from the Multifactor Leadership Questionnaire, Total Commitment
Employment Survey, and the Perceived Wellness Survey. The quantitative data
were analyzed through multivariate analysis techniques including correlation
and regression analysis. This was followed by a qualitative component where
data were collected from 12 officers through semi-structured interviews and
examined through thematic analysis. Findings reveal that transformational
leadership was negatively related to affective and normative commitment as well
as spiritual and intellectual wellness. In contrast, transactional leadership that
is typified by rewards and consequences was positively related to both outcomes.
The results also confirmed that continuance commitment, which is associated
with an employee’s need to stay with an organization due to benefits or lack of
alternatives, moderated the relationship between leadership (transactional and
transformational) and wellness. These results challenge the efficacy of
transformational leadership in a Caribbean policing context and suggest that
leadership may be contextual when examining its effect on commitment and
wellness
GlobalGeoTree: a multi-granular vision-language dataset for global tree species classification
No full textGlobal tree species mapping using remote sensing data is vital for biodiversity monitoring, forest
management, and ecological research. However, progress in this field has been constrained by the scarcity of
large-scale, labeled datasets. To address this, we introduce GlobalGeoTree, a comprehensive global dataset for
tree species classification. GlobalGeoTree comprises 6.3 million geolocated tree occurrences, spanning 275 families, 2734 genera, and 21 001 species across the hierarchical taxonomic levels. Each sample is paired with
Sentinel-2 image time series and 27 auxiliary environmental variables, encompassing bioclimatic, geographic,
and soil data. The dataset is partitioned into GlobalGeoTree-6M, a large subset for model pretraining, and curated evaluation subsets, primarily GlobalGeoTree-10kEval, a benchmark for zero-shot and few-shot classification. To demonstrate the utility of the dataset, we introduce a baseline model, GeoTreeCLIP, which leverages paired remote sensing data and taxonomic text labels within a vision-language framework pretrained on
GlobalGeoTree-6M. Experimental results show that GeoTreeCLIP achieves substantial improvements in zeroand few-shot classification on GlobalGeoTree-10kEval over existing advanced models. By making the dataset,
models, and code publicly available, we aim to establish a benchmark to advance tree species classification
and foster innovation in biodiversity research and ecological applications. The code is publicly available at
https://github.com/MUYang99/GlobalGeoTree (last access: 10 February 2026), and the GlobalGeoTree dataset
is available at https://doi.org/10.15468/dd.9qxqyy (Mu et al., 2025b)
Cauchemar
No full textCauchemar is a collaborative publication by Susanne Clausen and Pavlo Kerestey, developed within their joint practice as Szuper Gallery. Structured as both documentation and reflection, the book moves between different media and shifts in tone, foregrounding mediation itself as a central concern.
The introductory text centres on the radio interview that forms the conceptual core of the project: a public conversation between a Ukrainian writer and a German journalist. It reflects on the structure and atmosphere of this exchange, attending to hesitation, interruption, imbalance, and the violence embedded in the dialogue. The focus lies on how positions are asserted and deflected, and on how a debate staged as dialogue reveals deeper fractures within European political discourse. The interview is approached as a symptomatic document that exposes the difficulty of speaking across radically different lived realities.
The publication then presents a documentary rendering of two re-staged performances in which handmade puppets, modelled as distorted doubles of the artists, stand in for the original speakers. These figures act as proxies, carrying the recorded voices while introducing a visible layer of displacement. Film stills are interwoven with selected excerpts, leading to the complete English translation of the interview. Read in full, the transcript allows duration and repetition to take effect, making perceptible the emotional strain embedded in the exchange and the uneasy gap between voice and body.
Installation views from the exhibition at Voloshyn Gallery in Miami follow. They show how the filmed re-enactment was situated within the gallery space, where projected text and the physical presence of the puppets extend the interview into a spatial setting. Language shifts from broadcast to staged performance, and then into exhibition.
A short text introduces the final section of ink drawings derived from archival photographs, family images, and circulated media fragments. These works do not reproduce their sources directly. Instead, they rework them through erasure and distortion, functioning as visual counterparts to the interview and holding unresolved tension.
Across its components, Cauchemar operates as archive and intervention, asking how speech and image might register historical rupture without resolving it
Picturing Herakles’ athloi and parerga in late Archaic and early Classical Athens
No full textHerakles was single most important figure decorating Athens’ late Archaic pottery. These images crystallize his role as paradigm of victory. Through his sheer athleticism, Herakles serves as a role model for athletes, which in part explains his relevance on Attic vases with Panathenaic imagery alongside the boar, deer, bull, and especially lion labors. Both his status as an athletic hero and the pots, especially the sketchy late black-figure wares, would have increased his renown among Athenians and others, fans and other participants in festivals, especially the Panathenaia. For images of Herakles’ role in the Gigantomachy and/or other battles with giants bring him closer to Athena and thus to Athens, literally in the case of Alkyoneus, who he encounters at Pallene, the gates of Athens. In Nemean Ode 1.67-72, Pindar celebrates Herakles’ part in the Gigantomachy alongside his apotheosis and marriage to Hebe, which become entwined in his worship at Gargettos by Pallene, on the outskirts of Athens. Here the tyrant Peisistratos or his marketing manager seemingly brought myth, religion, and politics together: Pallene was both the site of his routing of forces and the starting point of his procession to the Akropolis with Athena/Phyia. Boardman and others have explained Herakles’ overwhelming importance in the vases of Archaic Athens vis-à-vis his connection to Athena, which was deliberately employed by Peisistratos and his sons. No less important, however, are Herakles’ growing roles—through the examples of his labors—in the Panathenaia, as an athlete and victor, also in the Gigantomachy, which became the foundational myth of the Panathenaia. We know that Herakles’ labors, parerga, and much else, were played out on stage in late Archaic and early Classical Athens and beyond. Although the relevant plays have not survived, enough fragments and titles remain to show the importance of Herakles as both tragic and comic character on the Athenian stage. Images on Athenian ceramics, decorated with mythic and historic images known in late Archaic and early Classical Athens, witness this story-telling culture through which Athenians embraced Herakles, alongside Theseus, as one of their own
Exploring one of the darker sides of expatriation: Chinese expatriates’ experiences with petty corruption in Tanzania
Get PDFDrawing on institutional isomorphism and Bourdieu’s concept of capital, this ethnographic study provides a comprehensive examination of how institutional pressures interact with individual capital (linguistic, cultural and social) to shape expatriates’ behaviours in dealing with local petty corruption practices. We find that co- ercive isomorphism is often intensified by a lack of local linguistic capital, mimetic isomorphism is reinforced by uncertainty in a foreign environment, and normative isomorphism is shaped by norms and expectations origi- nating from both the host and home countries, rather than being solely rooted in the local environment. Our findings highlight the critical role of individual capital as a moderator of institutional responses. By bridging macro-level neo-institutional theory and micro-level practices, this study deepens our understanding of how expatriates’ behaviour is shaped by both broader institutional environments and the personal resources they bring to their host country
