No full textCULEMO: Cultural Lenses on Emotion - Benchmarking LLMs for Cross-Cultural Emotion Understanding
No full textNLP research has increasingly focused on subjective tasks such as emotion analysis. However, existing emotion benchmarks suffer fromtwo major shortcomings: (1) they largely rely on keyword-based emotion recognition, overlooking crucial cultural dimensions required fordeeper emotion understanding, and (2) many are created by translating English-annotated data into other languages, leading to potentially unreliable evaluation. To address these issues, we introduce Cultural Lenses on Emotion (CuLEmo), the first benchmark designedto evaluate culture-aware emotion prediction across six languages: Amharic, Arabic, English, German, Hindi, and Spanish. CuLEmocomprises 400 crafted questions per language, each requiring nuanced cultural reasoning and understanding. We use this benchmark to evaluate several state-of-the-art LLMs on culture-aware emotion prediction and sentiment analysis tasks. Our findings reveal that (1) emotion conceptualizations vary significantly across languages and cultures, (2) LLMs performance likewise varies by language and cultural context, and (3) prompting in English with explicit country context often outperforms in-language prompts for culture-aware emotion and sentiment understanding. The dataset and evaluation code is available

The Evolution of the Common Law with Strategic Litigants
No full textThe common law is shaped by the cases that are litigated in court. We study the incentives for litigants to influence legal evolution by strategically choosing which disputes to litigate. In our framework, clarifying the law typically benefits defendants. This creates a strict incentive for plaintiffs to settle cases, or to abandon legal claims even when litigation is costless. When plaintiffs are regulators, we associate this scenario with ‘regulator capture’. By contrast, defendants may generate ‘test cases’ to force litigation which clarifies the law, in instances where plaintiffs would ordinarily not litigate. We predict that settlement and this form of regulatory capture is most likely when regulators are sufficiently long-run oriented, whilst test cases arise when defendants are long-run oriented. We analyze the welfare consequences arising from these dynamic incentives
Reflections in Black: A Reframing
No full textReflections in Black: A Reframing includes modern and original prints and extends Deborah Willis’s pioneering effort to reshape the narrative of American history, by centering the indisputable aesthetic, political, and cultural contributions of Black photographers from the 19th century to the present. Featured in the exhibition is The Missing Chapter: Black Chronicles, Autograph’s pop-up photography display featuring 30 remarkable image panels, reproduced from rare 19th-century photographs portraying people of African, Caribbean and South Asian descent during the Victorian era in Britain. Focused on unearthing nineteenth-century photographs of black presences in Britain’s archives, the portraits offer a unique snapshot of black lives and experiences during the decades following the birth of photography in 1839. Many of these images lay buried deep within the archives for decades, unseen for more than 125 years. Through both historical and contemporary lenses, Reflections in Black: A Reframing foregrounds a sweeping visual archive that affirms Black self-authorship in image making, spotlighting the evolution and enduring vitality of Black photographic practices

No full textThe recent detection of the phosphorus monoxide cation (PO+) in the interstellar medium (ISM) has generated considerable interest in its collisional excitation and reactivity in such environments. Due to the difficulties in conducting laboratory experiments in these extreme environments, theoretical calculations have become essential to model the excitation and reactivity of PO+. In this context, several theoretical studies have been conducted to better understand its abundance and impact on interstellar chemical processes. An important aspect of these studies is the accurate characterization of their electronic interaction with the surrounding gas constituents. We present here a new four-dimensional potential energy surface (PES) for the interaction between the PO+ cation and the H2 molecule, the dominant species in the cold ISM, using the explicitly correlated coupled cluster method with single, double, and perturbative triple excitations [CCSD(T)-F12a]. The rigid rotor PES provides a global representation of the PO+-H2 interaction, and presents a unique global minimum with a well depth of 1252.88 cm–1. We subsequently characterized the rovibrational states of the PO+-H2 complex, up to a total angular momentum J of 3, by solving the nuclear Schrödinger equation with the block-induced relaxation procedure implemented in the Heidelberg Multi-Configuration Time Dependent Hartree (MCTDH) package. We obtained zero-point energies of 422.201 cm–1 for PO+-para-H2 and 487.805 cm–1 for the PO+-ortho-H2 complex. This corresponds to dissociation energies (D0) of 830.679 and 765.075 cm–1for PO+-para-H2 and of 487.805 cm–1 for the PO+-ortho-H2 complex. We hope that the present theoretical results will stimulate experimental studies of the PO+-H2 complex in order to validate the predictions reported in this work
Data from a throughfall exclusion experiment: Fine root dynamics, morphology, chemistry, and AMF colonization across four lowland Panamanian forests
No full textFine roots regulate forest nutrient, carbon, and water cycling, yet their variation within and among tropical forests remains under-characterized. We quantified root productivity, disappearance, and stocks to 1 m using minirhizotron imaging, and we measured morphology, elemental composition [root carbon (C), root nitrogen (N), root phosphorus (P)], and arbuscular mycorrhizal fungi (AMF) colonization to 20 cm using ingrowth cores and sequential coring. Sampling took place in four distinct lowland Panamanian forests (32 plots; 8 per forest) from 2018 through 2022 under control and throughfall-exclusion (drought) treatments in the Panama Rainforest Changes with Experimental Drying (PARCHED) experiment.
The dataset is presented as an Excel workbook with six tabs. The first tab is the data dictionary. Tab S1 contains ingrowth-core production and mortality, morphology and soil moisture. Tab S2 contains sequential-coring standing stocks with associated morphology and soil moisture. Tab S3 contains minirhizotron row data records to 1 m depth, including per-frame root length and diameter, normalized length metrics, and session timing. Tab S4 contains AMF colonization. Tab S5 contains fine-root chemistry at 0–10 cm, reporting %P, %C, %N, and C:N for samples collected via ingrowth cores and sequential-coring standing stocks. CSV mirrors for each tab are provided, and a KML file supplies coordinates for all 32 plots.
Key variables span live and dead fine-root biomass (and coarse fractions where applicable), specific root length (SRL) and area (SRA), diameter, root tissue density (RTD), soil moisture, AMF colonization, root %N, %C, %P, and C:N, along with minirhizotron root length and diameter. Depth, season, treatment, and plot/site identifiers are included to support cross-tab integration and analysis from 0–100 cm (minirhizotron) and 0–20 cm (cores).
Units are reported in-column and missing values are coded as NA. No special software is required to open or use the files (Excel, CSV, and KML compatible)
