We explore a new approach for the parsimonious, generalizable, efficient, and potentially automatable characterization of spectral diversity sparse targets in spectroscopic imagery. The focuses on pixels which are not well modeled by linear subpixel mixing Substrate, Vegetation Dark (S, V, D) endmember spectra dominate variance most Earth’s land surface. illustrate using AVIRIS-3 imagery anthropogenic surfaces (primarily hydrocarbon extraction infrastructure) embedded background Arctic tundra near Prudhoe Bay, Alaska.

The psychosocial impacts of skin-neglected tropical diseases (SNTDs) as perceived by the affected persons: A systematic review

PLoS neglected tropical diseases, Journal Year: 2024, Volume and Issue: 18(8), P. e0012391 - e0012391

Published: Aug. 2, 2024

Background Neglected Tropical Diseases (NTDs) disproportionately affect marginalised groups within impoverished communities, conferring devastating physical, financial and psychosocial effects. Skin-NTDs (SNTDs) are uniquely stigmatising due to their visible nature, rendering affected individuals vulnerable risk the associated decline in social participation, quality of life mental health. In response knowledge gaps identified by current global efforts for integrated control SNTDs this review gathers existing evidence on effects SNTDs, with consideration given influence gender. Methods The study protocol is registered PROSPERO (CRD42022336676). Data was collected from Embase, Global Health, Medline Web Science, additional articles through Google Scholar bibliography tracking. Qualitative studies published English between 2005 2024 reporting men’s women’s experiences were searched. Appropriate data each included inputted into NVivo software facilitate thematic synthesis. Descriptive analytic themes generated line-by-line coding using an inductive approach. Results 27 high moderate included. They pertained buruli ulcer, cutaneous leishmaniasis, leprosy, lymphatic filariasis, tungiasis, onchocerciasis, schistosomiasis podoconiosis. Men women across contexts reported debilitating physical symptoms which impaired ability work, socialise carry out usual daily activities. Some felt (at least initially) well supported partners relatives, whereas most experienced avoidance, abandonment even violence, incurring worse SNTD-related consequences. Many men stigma, discriminatory behaviours largely attributed fear infection, decreased perform gender-specific activities, perceived association sinfulness. Self-reported impacts wellbeing low mood, anxiety, self-esteem, suicidal ideation. Disease-specific knowledge, early treatment, support, disease acceptance mentioned as protective factors. Conclusion cause significant harms, particularly women. Implementing myth-busting contact-based educational campaigns improving access treatment livelihood opportunities protection schemes a SNTD will help prevent mitigate these.

‘We Herders Are Often Chased About by Drought’: A Systems Analysis of Natural Resource Degradation Within the Climate–(Im)mobility–Violence–Health Nexus in Sahel

Earth, Journal Year: 2025, Volume and Issue: 6(1), P. 11 - 11

Published: Feb. 13, 2025

This study applies a systems analysis to further our understanding of the many pathways linking climate stress human (im)mobility and interpersonal violence via natural resource within eight countries (Burkina Faso, Chad, Mali, Mauritania, Niger, Nigeria, Senegal, Sudan) across Sahel region. To illustrate multiple climate–(im)mobility–violence–health nexus, contextual conceptual maps were drawn out based on secondary qualitative data from 24 peer-reviewed journal articles selected search result 394 publications. Even though geography, environment, socio-political context, traditions, cultural history highly diverse, overarching factors that determined people’s health outcomes, in association with violence, very similar. These vulnerability included gendered immobility, conflict, lack social protection, which provide important lessons offer tangible opportunities for policy interventions. The often eroded access resources positive (mental) ended up entrapping people extended cycles exploitation—especially certain intersectional positions disadvantaged groups (whether household, society, or country).

Divergent trajectories of Arctic change: Implications for future socio-economic patterns

AMBIO, Journal Year: 2024, Volume and Issue: unknown

Published: Oct. 30, 2024

Abstract Climate change is causing rapid warming in the Arctic, which, alongside other physical, socio-economic, cultural, geopolitical, and technological factors, driving far north. This research presents a conceptual model summarizing Arctic factors which turn was used design of Delphi exercise leveraged variety experts to forecast trajectories different parts Arctic. Based on these experts’ expectations for economic governance outcomes by 2050, we find that our results illustrate “many Arctics” concept or some ways heterogenous now, perhaps becoming increasingly so future. Sub-regions differed expert about future resource extraction, tourism, Indigenous self-determination, military activity, among outcomes. work also discusses post-2022 geopolitical situation potential implications policy governance.
