Life and Death in Hegelian Judgements
Authors: Giladi Tal Meir 
Published: February 2025

Abstract
Hegel contends that judgements are contradictory, finite and untrue. Prominent scholars argue that Hegel’s issue with judgements is resolved in the later stages of his Logic. Specifically, Ng suggests that this solution is found in Hegel’s discussion of life. In this article, I argue that not only does life fail to resolve Hegel’s problem with judgement—death highlights its insolubility. To support this claim, I examine Hegel’s discussion of judgements in the Logic, showing that judgements are inherently contradictory because they both unite and separate individuals and universals. Instead of being resolved retrospectively, I demonstrate that contradiction, finitude and untruth are intrinsic to judgements. Moreover, since judgements play a constitutive and determinative role in Hegel’s metaphysics, they pass their contradictions, finitude and untruth onto the objects they constitute. Specifically, I argue that for living beings, judgement is literally a matter of life and death, because the contradiction of judgements implies the finitude of the objects they constitute—namely, the perishability of things and the mortality of organisms.
Exploring the spatially resolved initial mass function in SAMI star-forming galaxies

Published: February 2025

Abstract
The initial mass function (IMF) is a construct that describes the distribution of stellar masses for a newly formed population of stars. It is a fundamental element underlying all of star and galaxy formation, and has been the subject of extensive investigation for more than 60 years. In the past few decades there has been a growing, and now substantial, body of evidence supporting the need for a variable IMF. In this light, it is crucial to investigate the IMF’s characteristics across different spatial scales and to understand the factors driving its variability. We make use of spatially resolved spectroscopy to examine the high-mass IMF slope of star-forming galaxies within the SAMI survey. By applying the Kennicutt method and stellar population synthesis models, we estimated both the spaxel-resolved (α
res
) and galaxy-integrated (α
int
) high-mass IMF slopes of these galaxies. Our findings indicate that the resolved and integrated IMF slopes exhibit a near 1:1 relationship for α
int
≳ –2.7. We observe a wide range of α
res
distributions within galaxies. To explore the sources of this variability, we analyse the relationships between the resolved and integrated IMF slopes and both the star formation rate (SFR) and SFR surface density (ΣSFR). Our results reveal a strong correlation where flatter/steeper slopes are associated with higher/lower SFR and ΣSFR. This trend is qualitatively similar for resolved and global scales. Additionally, we identify a mass dependency in the relationship with SFR, though none was found in the relation between the resolved slope and ΣSFR. These findings suggest an scenario where the formation of high-mass stars is favoured in regions with more concentrated star formation. This may be a consequence of the reduced fragmentation of molecular clouds, which nonetheless accrete more material.
From Open Doors to Closed Minds: The Transformation of Perceptions Toward Syrian Refugees in Turkey
Authors: Cevik Haci 
Published: February 2025

Abstract
This study investigates the impact of historical and ideological continuities in Turkey’s migration policies on contemporary attitudes toward Syrian refugees. It examines how ethnic homogenization and discrimination, rooted in the foundation of the Turkish Republic, continue to shape public perceptions and policy frameworks. The research is based on qualitative methodologies, including 41 semi-structured in-depth interviews conducted between July and December 2021 with Syrian refugees and Turkish community members residing in Altındağ, Mamak, and Ümitköy districts of Ankara. Participants were purposively selected to provide diverse perspectives on social integration and identity formation. The findings reveal a shift from initial acceptance under religious solidarity to increasing exclusion, driven by nationalist rhetoric. Despite official claims of promoting multiculturalism, Turkish policies and societal attitudes often reinforce prejudices, fostering a socio-political environment where racial and ethnic biases persist.
PETRUS VICTORIUS AND ARISTOTLE'S EUDEMIAN ETHICS
Authors: Rowe Christopher 
Published: February 2025

Abstract
This article reassesses the contribution of the late Renaissance scholar and teacher Petrus Victorius (Pier Vettori) to the reconstruction of the text of Aristotle's Eudemian Ethics, which has come down to us in what is often a highly corrupt form. It proposes an interpretation of certain abbreviations in the marginalia in one of Victorius's copies of the Aldine Eudemian Ethics which reveals them as recommending readings rather than recording them; it proposes that many more of those readings constitute his own conjectures than previously thought. The article goes on to suggest why Victorius never produced an edition of the Eudemian Ethics as he did of other Aristotelian works, despite returning repeatedly, over much of his life, to the task of improving this particular text. Victorius is revealed nonetheless as a highly creative—but also highly disciplined—textual critic, at least the equal of his nineteenth- and twentieth-century successors.
Social Media and the Politics of Ironic Belonging in Dubai
Authors: Pahwa Sonali 
Published: February 2025

Abstract
Social media content creation is hugely popular with second-generation Arab immigrants to the UAE who lack a path to naturalized citizenship, particularly as a space to perform their belonging in the nation. This essay analyzes the work of two Arabophone content creators on Instagram and YouTube who use comedy to perform as quintessential “Dubai kids.” While they align with the state mission of presenting the UAE positively on social media, these creators produce ironic content that makes visible practices of belonging by second-generation youth who distance themselves from inherited politics of national and gender identity. The affective communities that form around these satirical content creators offer a model of belonging in which binaries of citizen and noncitizen can be elided, staging performances of immigrant identity uniquely local to the UAE.
Navigating the currents: understanding awareness, attitudes, and menstrual hygiene management challenges in Bangladesh’s Haor Region

Published: February 2025

Abstract
Menstrual hygiene management (MHM) is an important but often neglected aspect of women’s health worldwide, especially in developing and disaster-prone countries, such as Bangladesh. This qualitative study aimed to investigate awareness, attitudes, and practices related to MHM among girls in the Haor region, particularly during floods. The study adopts a phenomenological approach, and data were collected using purposive sampling from 33 women aged 15 years and above who resided in the Haor region. Thematic analysis was employed to identify the patterns, themes, and subthemes within the qualitative data. The study reveals a significant lack of widespread knowledge about menstruation among girls in the Haor area, which is associated with unfavourable family and social attitudes, and stigma or taboos. Natural hazards, cultural barriers, access to the market, economic incapacity, and inadequate infrastructure make it very difficult to manage menstruation, which is especially aggravated during floods due to displacement and shelter on the roadside, primary schools, and other people’s houses. This research emphasises the need for tailored MHM programmes from the government to address the unique challenges faced by women in Haor regions. Provision of sanitary napkins and essential medicines, maintaining stock in shelters, and equipping community clinics with MHM-related healthcare services are essential. Finally, NGOs should prioritise MH within their scope of work.

Published: February 2025

Abstract

Background
Previous studies (various designs) present contradicting insights on the potential causal effects of diet/physical activity on depression/anxiety (and vice versa). To clarify this, we employed a triangulation framework including three methods with unique strengths/limitations/potential biases to examine possible bidirectional causal effects of diet/physical activity on depression/anxiety.

Methods
Study 1: 3-wave longitudinal study (n = 9,276 Dutch University students). Using random intercept cross-lagged panel models to study temporal associations. Study 2: cross-sectional study (n = 341 monozygotic and n = 415 dizygotic Australian adult twin pairs). Using a co-twin control design to separate genetic/environmental confounding. Study 3: Mendelian randomization utilizing data (European ancestry) from genome-wide association studies (n varied between 17,310 and 447,401). Using genetic variants as instrumental variables to study causal inference.

Results
Study 1 did not provide support for bidirectional causal effects between diet/physical activity and symptoms of depression/anxiety. Study 2 did provide support for causal effects between fruit/vegetable intake and symptoms of depression/anxiety, mixed support for causal effects between physical activity and symptoms of depression/anxiety, and no support for causal effects between sweet/savoury snack intake and symptoms of depression/anxiety. Study 3 provides support for a causal effect from increased fruit intake to the increased likelihood of anxiety. No support was found for other pathways. Adjusting the analyses including diet for physical activity (and vice versa) did not change the conclusions in any study.

Conclusions
Triangulating the evidence across the studies did not provide compelling support for causal effects of diet/physical activity on depression/anxiety or vice versa.

Abstract

Objective:
To understand caregivers’ perceptions about their children’s mealtime social experiences at school, and how they believe these social experiences impact their children’s consumption of meals at school (both meals brought from home and school meals).

Design:
Qualitative data were originally collected as part of a larger mixed methods study using an embedded-QUAN dominant research design.

Setting:
Semi-structured interviews were conducted with United States (U.S.) caregivers over ZoomTM in English and Spanish during the 2021-2022 school year. The interview guide contained 14 questions on caregivers’ perceptions about their children’s experiences with school meals.

Participants:
Caregivers of students in elementary, middle, and high schools in rural, suburban, and urban communities in California (n=46) and Maine (n=20) were interviewed. Most (60.6%) were caregivers of children who were eligible for free or reduced-price meals.

Results:
Caregivers reported that an important benefit of eating meals at school is their child’s opportunity to socialize with their peers. Caregivers also stated that their child’s favorite aspect of school lunch is socializing with friends. However, some caregivers reported the cafeteria environment caused their children to feel anxious and not eat. Other caregivers reported that their children sometimes skipped lunch and chose to socialize with friends rather than wait in long lunch lines.

Conclusions:
Socializing during school meals is important to both caregivers and students. Policies such as increasing lunch period lengths and holding recess before lunch have been found to promote school meal consumption and could reinforce the positive social aspects of mealtime for students.
Demographic and Dietary Determinants of the Association between Dietary Fiber Intake and Obesity in Japanese Adults with Type 2 Diabetes: A Cross-Sectional Study (JDDM 78)

Abstract

Objective:
To evaluate the association between dietary fiber intake and obesity in Japanese outpatients with type 2 diabetes, as well as the demographic and dietary factors influencing this association.

Design:
Cross-sectional study with nationwide registry data on Japanese type 2 diabetes outpatients (2014-2019). Diet was self-reported via a Food Frequency Questionnaire. Obesity was defined as BMI ≥25 kg/m2.

Setting:
Clinics throughout Japan.

Participants:
1,565 Japanese outpatients with type 2 diabetes (63.1% men; age range 30–89 years).

Results:
Multivariate analysis revealed that a higher dietary fiber intake was associated with a lower risk of obesity in all participants (95% CI = 0.439–0.795, p < 0.001). Stratified analysis showed a significant inverse association between fiber intake and obesity in men and the older age groups (59–89 years), but not in women or the younger age group (30–58 years). In men, higher fiber intake was associated with healthier lifestyle behaviors, including increased physical activity (p < 0.001) and non-smoking (p < 0.001), with stronger associations compared to women. Vegetables, fruits, and soybeans/soy products were strongly correlated with fiber, while grains had a weak correlation. Folate was the micronutrient most strongly correlated with fiber.

Conclusion:
Higher fiber intake was associated with lower obesity risk, particularly in men and older age groups. These findings emphasize the need for targeted public health initiatives promoting the intake of diverse fiber-rich foods to effectively manage obesity. Further research is needed to understand sex- and age-specific factors in the fiber-obesity relationship in diverse populations.
Influence of planning target volume margins using various prescription isodoses in gamma knife radiosurgery for single brain metastasis: a phantom study
Authors: Fiagbedzi Emmanuel , Tagoe Samuel Nii Adu , Hasford Francis , Nisbet Andrew 
Published: February 2025

Abstract

Objective:
The study seeks to evaluate the influence of planning target volume (PTV) margins on plan parameters during inverse planning of brain metastases with the Gamma Knife treatment unit, considering various prescription isodose levels (PIL).

Material & Method:
CT scan images of a STEEV anthropomorphic phantom were transferred into the GAMMA PLAN Treatment Planning System. A target measuring a volume of 4·9cc was centrally contoured. Plans with a 0 mm volume margin at five prescription isodose levels from 50% to 70% at 5% increment were created. With 0.5 mm, 1 mm, 1.5 mm and 2 mm PTV margins, identical plans were regenerated. Adjustments were made to each plan when necessary to achieve same target coverage. One-way ANOVA test was used to analyse the influence of PTV margins on parameters including Selectivity[S], Gradient index [GI], V12, Paddick’s conformal index [PCI] and Treatment time [TI].

Results:
Margin addition resulted in PTV volume increase. The findings indicated that the PTV margin of 2.0 mm exhibited the highest mean selectivity of (0.93 ± 0.00), PCI (0.92 ± 0.01), GI (2.50 ± 0.04), V12 (16.17 ± 0.38) and treatment time (118.32 ± 2.91 min). The 0.0 mm PTV margin had the lowest mean value for all the parameters except for the treatment time (105.58 ± 3.48 min) which was slightly higher compared to the 0.5 mm PTV margin (M = 86.36 ± 4.13 min).

Conclusion:
Incremental increases in PTV margins for Gamma knife radiosurgery though a relatively controversial concept influence all dosimetric parameters, which may pose potential detrimental effects and thus need to be carefully evaluated for brain metastasis treatment.
Nitrogen Biogeochemistry of Adjacent Mesoscale Eddies in the North Pacific Subtropical Gyre

Published: February 2025

AbstractWe examined the nitrogen (N) biogeochemistry of adjacent cyclonic and anticyclonic eddies near Hawai'i in the North Pacific Subtropical Gyre (NPSG) and explored mechanisms that sustain productivity in the cyclone after the initial intensification stage. The top of the nutricline was uplifted into the euphotic zone in the cyclone and depressed in the anticyclone. Subsurface nutrient concentrations and apparent oxygen utilization at the cyclone's inner periphery were higher than expected from isopycnal displacement, suggesting that shallow remineralization of organic material generated excess nutrients in the subsurface. The excess nutrients may provide a supply of subsurface nutrients to sustain productivity in maturing eddies. The shallow remineralization also raises questions regarding the extent to which cyclonic eddies promote deep carbon sequestration in subtropical gyres such as the NPSG. An upward increase in nitrate 15N/14N isotope ratios below the euphotic zone, indicative of partial nitrate assimilation, coincided with negative preformed nutrients—potentially signaling heterotrophic bacterial consumption of carbon‐rich (nitrogen‐poor) organic material. The 15N/14N of material collected in shallow sediment traps was significantly higher in the cyclone than in the anticyclone and showed correspondence to the 15N/14N ratio of the nitrate supply, which is acutely sensitive to sea level anomaly in the region. A number of approaches were applied to estimate the contribution of N2 fixation to export production. Results among approaches were inconsistent, which we attribute to non‐steady state conditions during our observation period.
A Terrestrial Thermometer Using Carbonate Clumped Isotopes From Gar Scales
Authors: Gray Katelyn E. , Brandon Mark T. 
Published: February 2025

AbstractWe present a new clumped isotope calibration relating temperature to the Δ47 composition of the bioapatite scales of gar fish (Lepisosteidae family). Modern gars live at <∼3 m depth in rivers and lakes, are non‐migratory, and their scales grow continuously over their lifespan (∼8–14 years). As ectotherms, their body temperature is equivalent to ambient water temperature. These features indicate that the Δ47 composition of gar scales may be useful for measuring the surface temperature in present and past terrestrial settings. Fossil gar scales are widely distributed in time (Cretaceous to modern) and location (North and South America, Europe, India, and Africa), and are highly mineralized and resistant to diagenesis. Our calibration is based on modern gars collected from eight locations in North America. We use climate data to convert the variable temperature in the gar's habitat into an effective temperature, Te, to account for variable growth. For our samples, Te ranges from 13.8 to 27.1°C. We report a lab protocol for measuring the Δ47 composition of gar scale bioapatite with a reproducibility of 0.019‰ (1 SD). Our calibration is based on 19 samples, with ∼3 replicate measurements per sample. The result is Δ47 = (0.1206 ± 0.0171) × 106/Te2 – (0.7429 ± 0.0587) (1 SE), with R2 = 0.75 (Δ47 in ‰ and Te in K). The slope of this calibration is steeper than that for the lab‐controlled precipitation of inorganic carbonate. We argue that this difference is caused by kinetic isotope effects associated with hydroxyapatite biosynthesis.
Ocean Chlorophyll Feedback in a Coupled Ocean‐Atmosphere Model for the Mediterranean and Black Seas

Published: February 2025

AbstractOcean water clarity, influenced by marine chlorophyll concentration, significantly alters the distribution of shortwave radiation in the water column. This work aims to assess the effects of varying chlorophyll on the upper‐ocean physical properties and their subsequent impact on the atmosphere, using a coupled ocean‐atmosphere regional model for the Mediterranean and Black Seas. We performed 11‐year (2011–2021) twin‐simulation experiments based on different chlorophyll concentrations to estimate the penetration of solar radiation in the ocean. The first simulation used a monthly climatology field of chlorophyll concentrations derived from satellite observations, while in the second experiment, the chlorophyll concentration was kept constant at 0.05 , representing clear water conditions. Results show that radiative heating driven by chlorophyll amplifies the seasonal cycle of temperature in the upper layers, leading to increased surface warming in summer and surface cooling in winter. Also, higher surface chlorophyll contributes to cooling in subsurface layers throughout the year due to its shading effect. The temperature response to chlorophyll variations is controlled by the mixed layer depth and a balance between (a) direct near‐surface radiative heating due to the chlorophyll absorption and (b) indirect cooling resulting from vertical turbulent mixing processes with subsurface waters. The atmosphere moderates the seasonal sea surface temperature (SST) response caused by chlorophyll differential heating primarily through changes in latent heat flux. Ultimately, our simulations suggest that increased surface chlorophyll concentrations enhance the Mediterranean overturning circulation, highlighting the necessity of incorporating realistic optical forcing into regional climate modeling studies.
Probabilistic Trade‐Offs Analysis for Sustainable and Equitable Management of Climate‐Induced Water Risks

Published: February 2025

AbstractPressures on water resources are fueling conflicts between sectors. This trend will likely worsen under future climate‐induced water stress, jeopardizing food, energy and human water security in most arid and semi‐arid regions. Probabilistic analysis using stochastic optimization modeling can characterize multi‐sector vulnerabilities and risks associated with future water stress. This study identifies the probabilistic trade‐offs between agricultural, urban and energy sectors in the Ebro Basin (Spain). Two intervention policies have been examined and compared: (a) agricultural priority, and (b) energy priority, for two planning horizons 2040–2070 and 2070–2100. Results show that the human water security goal is achieved under both intervention policies. However, the achievement of the food and energy security goals depends on the policy objectives and on the spatial location of irrigation schemes and hydropower plants, which result in different stream flows across the basin. The policy choice results in substantially different benefit gains and losses by sector and therefore by location. None of the sectoral production priority policy provides an equitable sharing of benefits among all sectors and locations under climate change, which is an important issue, because the success or failure of policy interventions would depend on the distribution of the gains and losses of benefits across the basin. Policy uptake by stakeholders would depend on reaching win‐win outcomes where losers are compensated, while delivering acceptable levels of food, energy and human water security in large river basins. Information on the probabilistic trade‐offs contributes to the design of water management strategies capable of addressing the multi‐sector vulnerability.
