This article recovers the lived experiences of trafficked Indigenous women in nineteenth-century Buenos Aires, Argentina. From 1878 through 1885, the Argentine Army carried out a series of campaigns in the Pampas and Patagonia, imprisoning and displacing thousands of formerly autonomous Indigenous people. Hundreds of prisoners, mostly women and children, were sent to Buenos Aires and placed under the jurisdiction of a women's charity organization called the Sociedad de Beneficencia (SdB). In conjunction with Argentina's Ministry of War, the SdB sent Indigenous women to live in the homes of wealthy Buenos Aires families as unfree domestic laborers. The SdB employed a racialized and gendered discourse of moral uplift to justify coercive treatment and sanitize ongoing frontier violence. This article reveals that some Indigenous women, unable to access protection under the law, attempted to shape their circumstances by publicly calling attention to mistreatment and neglect. These resistant actions forced Argentina's political elites to question the meaning of Argentine citizenship and national belonging. Ultimately, this article provides insights into the complex relationship among gender, race, and social class in the construction of settler colonial nation-states, highlighting the possibilities for Indigenous resistance under settler colonialism.
Large-scale structure measurements have revealed persistent tensions between early- and late-time cosmological probes, most notably the long-standing discrepancy in the structure-growth parameter S_8. In this work, we explore how a model including decaying dark matter (DDM) can alleviate this tension by suppressing the growth of matter fluctuations at late times. Specifically, we consider a neutrinophilic decay channel in which a heavy dark matter particle χ slowly decays into a Standard Model neutrino and a light invisible fermion, χ→ ν+ ϕ, modifying both the background evolution and the clustering of structure. Using the DES Year 1 redshift distributions, we construct a baseline matter power spectrum and compute the galaxy-galaxy, shear-shear, and galaxy-shear angular power spectra under both ΛCDM and DDM-inspired scenarios. We find that slow dark matter decay produces a scale-dependent suppression of clustering that remains consistent with DES measurements while naturally shifting the predicted structure amplitude toward the lower values favored by weak lensing surveys. Our results suggest that decaying dark matter is a compelling and physically motivated framework for addressing the S_8 tension.
This study investigates the impact of climate risk governance and green transformation initiatives on carbon mitigation performance. Using a sample of 276 compliant, carbon-sensitive, non-financial United Kingdom (UK) listed firms from 2011 to 2020, we find that climate risk governance mechanisms and green transformation initiatives improve carbon performance by minimizing actual carbon emissions. Our results also reveal that the joint effect of climate risk governance and green transformation initiatives, an indication of the quality of sustainable transformation aimed at addressing climate change, helps achieve sustained carbon mitigation performance. The results remain consistent after a battery of robustness tests and identification strategies. This study has important implications for management, policymakers, and other stakeholders concerning governance structure reforms and green transformation.
We investigated the influence of Active Galactic Nuclei (AGN) feedback on star formation in red spiral galaxies by analyzing a sample of 324 red and 273 blue face-on spirals selected from 115 low-redshift galaxy clusters. This multi-wavelength dataset combines optical emission line data from the Sloan Digital Sky Survey with X-ray fluxes from Chandra and XMM-Newton X-ray space telescopes. Using diagnostic emission line ratios, we constructed Baldwin-Phillips-Terlevich (BPT) diagrams, introduced in 1981 to classify galaxies based on nuclear activity. Our analysis reveals that most red spirals exhibit AGN or low-ionization nuclear emission-line region (LINER) signatures, based on optical data, as determined by their location in the BPT, Cid Fernandes, and Mazzolari diagrams. These results are consistent with the presence of negative feedback from AGNs quenching star formation. Conversely, X-ray analysis reveals that many blue spirals exhibit high X-ray luminosities and are situated in the AGN region of emission line ratio diagrams, suggesting that AGN-driven positive feedback may be enhancing star formation. Our findings support the hypothesis that AGN feedback plays a key role in the evolution of spiral galaxies, particularly in quenching star formation and driving the transition from blue to red spiral systems.
