Citizenship, as a legal status and societal construct shaped by physical and political boundaries, forms the bedrock of relations between nation-states and their inhabitants. However, contemporary forms of citizenship are challenging this concept by disassociating it from nations and territories, and instead linking it to societal struggles. Grounded in the notion that food practices can embody citizenship beyond legal definitions, the study explores the concept of food citizenship and how communities navigate belonging and participation. Drawing on theoretical frameworks from contemporary Western citizenship studies, this paper suggests the concept of “inclusive food citizenship” as a transformative force in fostering inclusive civic engagement and rights-claims within food systems. This conceptualisation emphasises collective action, democratic processes and inclusivity, aiming to address criticisms of elitism and exclusion inherent in current food citizenship discourse. Through a case study of community food initiatives in East-Central London, the paper illustrates practical applications of inclusive food citizenship. Employing a multi-method approach including interviews, participant observation and focus groups, the study explores how these initiatives promote social cohesion, resilience and equitable food systems amid challenges like funding constraints and limited governmental support. Ultimately, this research underscores the potential for food and other forms of citizenship to transcend legal and geographical boundaries, offering insights into fostering inclusive communities and addressing social injustices. It calls for ongoing dialogue and critical reflection to refine theoretical frameworks and advance practical models that uphold principles of justice, equity and sustainability in food governance and beyond. • Food citizenship emerges as a lens for exploring identity and civic engagement. • Alternative forms of citizenship transcend legal and geographical boundaries. • Food citizenship promotes inclusive communities and addresses social injustices. • Community food initiatives serve as democratic platforms for collective agency. • Community initiatives balance tackling food insecurity with broader democratic role.

Raman spectroscopy enables non-destructive chemical analysis and can be performed through-vial, eliminating air exposure. However, signal attenuation arises from refraction, absorption, and scattering within the sample, while distortions and spectral interference from the vial further degrade signal collection and data quality. This study investigates depth-dependent Raman intensity decay in polystyrene (PS) particle suspensions as a model for turbid liquids and proposes a framework of equations and approaches based on Mie scattering theory and the Beer-Lambert law to predict Raman intensity decay in a range of samples. Experimental validation was performed using aqueous suspensions containing 495 nm, 350 nm, and 200 nm PS particles using an 830 nm laser, with Raman spectra acquired at incremental depths. Peak areas corresponding to PS, water, and glass were recorded. Mie theory was used to model the UV-visible extinction response, yielding estimated absorbance and, combined with the intensity decay due to refraction established from non-turbid samples, Raman intensity decay lengths. Estimated decay lengths for PS and water showed good agreement with experimental values, typically within 20%. This framework enables rapid optimisation of focal depth and consistent comparison between samples and experiments for quantitative through-container Raman analysis in pharmaceuticals, materials science, and nanotechnology.

Alcohol use is driven not only by environmental cues but also by individual differences in motivational style. Recent work has demonstrated how memory cues can reduce subsequent desire for alcohol, yet it remains unclear how personality traits shape this effect. To address this, we recruited male and female participants ( N = 169) who completed the behavioural inhibition/approach system (BIS/BAS) scales and were then cued to recall either a previous alcohol drinking episode and estimate the number of alcohol calories consumed (Alcohol Cue, AC) or a control (Neutral Cue, NC). They then rated their desire for alcohol (DAQ). Findings revealed lower desire for those in the AC compared to NC group and separately, a positive association between alcohol desire and BAS and particularly BAS-Drive. We further found that a measure of residual BAS (BAS less BIS) was positively related to desire but did not moderate the effect of memory cue. These findings suggest that being reminded of a previous drinking episode can exert a modest but consistent influence on alcohol desire. • Memory of a recent drinking episode reduced alcohol desire in males and females. • Increases in Behavioural Approach System (BAS) increased alcohol desire. • BAS did not moderate the effect of the alcohol memory cue. • Memory cues could offer a simple method of reducing alcohol desire.

Introduction: Ovarian cancer is a leading cause of gynaecological cancer mortality. Ca125, the most widely used serum biomarker, has limited sensitivity for early-stage and type I tumours, prompting evaluation of additional blood-based markers. This umbrella review assesses the diagnostic and prognostic performance of serum and blood biomarkers in ovarian cancer.
