The elementary symmetric partition function is a map on the set of integer partitions. It sends a partition λ to the partition whose parts are the summands in the evaluation of the elementary symmetric function on the parts of λ . These elementary symmetric partition functions have been studied before, and are related to plethysm. In this note, we study properties of the elementary symmetric partition functions, particularly related to injectivity and the number of parts appearing in their image partitions.
The present study elucidates the oxidative stress response mechanisms of two marine cyanobacterial species, Phormidium sp. JMC111 and Microcoleus acutissimus, when exposed to hydrogen peroxide (H₂O₂). Both species tolerated short-term H₂O₂ stress up to 60 min, exhibiting significant biochemical and enzymatic adaptations. Statistical analysis revealed a steady decline in chlorophyll content and degradation efficiency over time, with M. acutissimus maintaining higher resilience compared to Phormidium sp. JMC111. Non-enzymatic antioxidants such as carotenoids, β-carotene, tocopherol, and astaxanthin remained elevated, suggesting a strong photoprotective and radical-scavenging defense, while ascorbic acid and phycobiliproteins declined under prolonged stress. Two-way ANOVA confirmed significant time- and species-dependent variations (p < 0.05) in antioxidant responses. Enzymatic assays on native PAGE revealed distinct isoform patterns of SOD, CAT, POD, and GPx, with the appearance of novel peroxidase and catalase isoforms under oxidative stress—reported here for the first time in marine cyanobacteria. These findings demonstrate that both cyanobacteria possess a dynamic and coordinated ROS defense network, with M. acutissimus showing superior antioxidative stability. The study identifies POD and CAT as reliable biochemical indicators of oxidative stress, establishing Phormidium sp. JMC111 as a potential biomonitor species for environmental oxidative assessment.
Scope of justice is the extent to which a person's beliefs about fairness and justice apply to others on the basis of their inclusion in one's moral community. Scope of justice narrows in times of societal conflict, making individuals less willing to share resources, and decreasing collaboration and trust. Governments and policy makers have a direct responsibility in shaping the scope of justice and interpersonal trust in society through the use of political narratives and their actions. When fear and threat-based narratives are activated, narrowing people's scope of justice, immigrants are criminalized and excluded. When desire and need-based narratives are activated, widening people's scope of justice by boosting interpersonal and institutional trust, political narratives normalize movement and support creating safe pathways for mobility. This paper explains a framework for just mobilities based on theories of narrative psychology, moral inclusion, and desire-based understanding of immigration. Evidence-based recommendations follow for policies and practices at the global, federal, state, local, and individual levels.
Background: Despite the efficacy of the Dietary Approaches to Stop Hypertension (DASH) diet, adherence remains low due to barriers, including food access, affordability, lack of tailored support. We hypothesized that a Food is Medicine intervention combining produce prescriptions with personalized dietitian coaching would improve dietary quality in high-risk populations. Methods: THRIVE was a 24-week, 2-arm randomized pilot feasibility trial conducted among Black and Hispanic adults with hypertension living in Healthy Food Priority Areas in Maryland (NCT06257550). Participants were randomized 1:1 to: (1) THRIVE intervention: $30/week produce prescription via “FARMacy” market + individualized DASH-aligned dietitian coaching + adaptive bi-directional text messaging + social resource navigation, or (2) Enhanced usual care (EUC): produce bags without coaching + social resource navigation. Outcome was a change in DASH adherence score (0-9 scale) via interviewer-administered 24-hour dietary recalls . Secondary outcomes included Healthy Eating Index (HEI 2015) total score, total fruit and vegetable intake assessed at 12 and 24 weeks. Intention-to-treat analyses were conducted using paired t-tests for within-group changes and difference-in-differences (DiD) for between-group tests. Results: Among 80 randomized participants (40 per group): mean age 54.5±11.4 years, 57% female, 62% Black, 34% Hispanic. At 12 weeks, both groups had improvements in DASH adherence scores (THRIVE: +0.33, 95% CI: -0.77, 1.43; EUC: +0.68, 95% CI: 0.06, 1.30, p=0.033, Table 1 ). By 24 weeks, improvements persisted in both groups (THRIVE: +0.78; Control: +0.25), DiD of +0.53 (95% CI: -0.88 to 1.94, p=0.452). There were clinically meaningful gains in total HEI scores in the THRIVE group at 12 weeks (+10.63, 95% CI: 2.85 to 18.40, p=0.010, Table 2 ) compared with EUC (+3.61, 95% CI: -1.83 to 9.06, p=0.186). At 24 weeks, HEI improvements were sustained in THRIVE (+6.44) vs. minimal change in EUC (+0.11), with a DiD of +6.32 (95% CI: -3.73 to 16.37, p=0.212). Vegetable intake increased at 12 weeks in the EUC group (+0.63 cups, 95% CI: 0.15 to 1.11, p=0.012) Conclusion: This pilot trial demonstrates the feasibility and promise of a multi-component Food is Medicine intervention to improve DASH diet adherence and overall diet quality among Black and Hispanic adults with hypertension. Preliminary results support the potential value of combining produce prescriptions with personalized nutrition support
This article examines how Muslimah influencers based in the United States, Canada, and the United Kingdom are policed for, and negotiate with the policing of their Islamic modesty in influencer culture. Data come from interviews with 14 Muslimah influencers, and a survey distributed amongst 188 self-identified followers of Muslim female influencers. Findings show that Muslimah influencers are policed by their followers, fellow modest fashion participants, and sometimes their families for prioritizing their nafs (self), violating Islamic principles of awrah (covering of private parts), and inviting their sexualization by others through the pursuit of influencer celebrity. Data show that Muslimah influencers respond to this policing through Islamic feminist Ijtihad (critical reasoning), positing their aesthetic labor as a form of dawah (proselytizing). This article argues that Muslimah influencers operate as 'pious critical agents' who employ Islamic feminism to broaden understandings of modesty as it operates in the lived realities of Muslim women in anti-Muslim contexts.
