Political Belonging in the Ghana-Togo Borderlands: Citizenship and the Vote at the Margins of the State

Nathalie Raunet’s Political Belonging in the Ghana-Togo Borderlands examines the construction of territorial political communities through a study of the Ewe, an ethnic group straddling the Ghana-T...

Cancer Screening and Citizenship Status in the US

Importance: Immigrants without US citizenship, or noncitizens, disproportionately endure poverty, labor exclusions, and inadequate health care access-structural drivers of adverse cancer outcomes. While screening is critical for preventing cancer deaths, and cancer is the leading...

Greenhouse gas emissions of subsea telecommunications cables: A comparative study of trans-Atlantic and trans-Pacific systems

Subsea cables are critical for international data exchange. Yet lifecycle assessments (LCA) remain scarce, leaving a critical gap in understanding both the climate impacts of these systems and wider global telecommunications networks. Drawing on a unique model of industry collabo...

Using a systematic review of youth and environmental youth participatory action research outcomes to create a modified implementation capacity framework

While youth participatory action research (YPAR), a youth-adult partnered or youth-led approach to knowledge generation and social change, has burgeoned over the last decade, challenges remain related to capacity for its implementation. Yet, the field lacks a YPAR implementation...

Sharing the Burden: The Impacts of Pharmacy Sector Reforms on the Labor Market for Pharmacists in Portugal

ABSTRACT During the 2010 crisis, the Portuguese government enacted several reforms to its prescription drug reimbursement system. As a result, value added per pharmacist in pharmacies fell by a third. We use longitudinal records from Quadros de Pessoal (QP), merged with collectiv...

Electrostatically Limited PFSA Ionomer Adsorption to Catalyst Particles in Catalyst Inks

Abstract Understanding and controlling ionomer adsorption in catalyst inks is critical to optimizing catalyst-layer structure and performance in membrane-electrode assemblies. Here, we systematically quantify perfluorosulfonic-acid (PFSA) ionomer adsorption across a diverse set o...

Catalyst Control of Alkylbenzene Molecular Architecture in Tandem Catalytic Hydrogenolysis-Aromatization of Polyethylene

Abstract Upcycling of polyethylene (PE) can transform waste material into chemically valuable building blocks such as linear alkylbenzenes, with potential use in anionic surfactants. Alkylbenzenes can be formed by tandem hydrogenolysis-aromatization of PE, catalyzed by Pt nanopar...

Disruptions as catalysts for change: exploring multi-year temporal dynamics of mobility styles

Abstract Disruptive events, ranging from extreme weather events to global pandemics, inevitably reshape the way people live, travel, and interact with their environments. Understanding both temporary shifts and longer-term behavioral adaptations in response to disruptions is crit...

Framing Displacement, Forcing Perspective: Black Visual Geographies and the Crisis of Homelessness in Oakland

ABSTRACT While Black and visual geographies have examined the image's racial and spatial power, more work is needed to analyze how racial frames of view become spatially embedded. This paper advances such a practice by analyzing news images of homelessness in Oakland. Methodologi...

Developing interactive learning interfaces for teaching AI in health professions education using generative AI tools

Health professions education (HPE) must now equip students to use artificial intelligence (AI) tools safely. We offer an instructional design strategy for HPE educators aiming to teach fundamental AI concepts to non-technical audiences: using generative AI to rapidly create inter...

Plant hormone manipulation impacts salt spray tolerance, which preempts herbivory as a driver of local adaptation in the yellow monkeyflower, Mimulus guttatus.

A major challenge in evolutionary biology is identifying the selective agents and phenotypes underlying local adaptation. Local adaptation along environmental gradients may be driven by trade-offs in allocation to reproduction, growth, and herbivore resistance. To identify enviro...

Impact of a health education intervention on knowledge, attitudes, and use of visibility materials among commercial motorcycle riders: a quasi-experimental study in Cameroon

Abstract Background Commercial motorcycle riders are among the most vulnerable road users in low- and middle-income countries, with poor visibility contributing significantly to road traffic crashes, particularly under low-light conditions. Visibility materials such as reflective...

The rise of carnivoran mammals in Europe through the lens of body mass

Carnivoran mammals (cats, dogs, bears, seals, etc.) and their kin radiated during the Palaeogene, among other carnivorous clades (hyaenodonts, mesonychians, and oxyaenodonts). This radiation has often been framed as a competition ultimately won by carnivorans, but the data suppor...

FullMS2Former:A Transformer Model for Near-CompletePrediction of Peptide Tandem Mass Spectra

Abstract Accurate prediction of peptide tandem mass spectra is essential for confident peptide identification. Existing deep learning models achieve high similarity to experimental spectra but remain constrained by fixed fragment dictionaries of common fragment ions, limiting the...

Hydration-dependent exciton-phonon coupling in a metal-organic framework photocatalyst

Abstract Metal-organic frameworks (MOFs) have potential for light-harvesting applications owing to their tunable optoelectronic properties via building block selection. The presence of bound solvent in MOFs is known to impact gas adsorption properties, but little is known about t...

Carrying Firearms and Suicide Risk Among Adolescents

Importance Firearms are the most lethal method of suicide across all ages, with case fatality rates exceeding 90%, warranting urgent public health concern. Understanding how carrying of firearms by adolescents and suicide risk vary by race and ethnicity and by stringency of state...

How the Land Speaks: “Native Culture” as Mediating Politics in Individual–Group Relationality

Abstract Indigenous peoples are often valorized as automatically politicized collective subjects, backgrounding the precise mechanics of individual-to-group political formation. In the case of “Native Hawaiian culture”, a locally invoked category of norms, practices, and knowledg...

Pike Use in Megafauna Hunting and Antipredator Defense: Historical Techniques and Paleolithic Research

This paper presents a comprehensive assessment of megafauna confrontation using pikes, as recorded in historical accounts and ethnographic studies depicting techniques of hunter-gatherers, pastoralists, colonial hunters and others. In contrast to the two other basic spear types,...

Slow change blindness from serial dependence: slowly changing objects are perceived as biased toward the past

Abstract Background Slow change blindness, when attentive observers fail to notice large changes that happen gradually, raises questions about how visual information is combined across time. One plausible integration strategy is serial dependence: blending information from the re...

Hidden Cost of Re-Engagement: Workload in Dynamic Multi-Operator Supervision of Autonomous Systems

Autonomous systems are increasingly shifting from single-agent oversight to distributed fleet supervision, where operators alternate between monitoring, waiting, and brief intervention. We examined whether multi-operator, multi-agent supervision preserves objective performance wh...
