Published: September 2024

AbstractThe ongoing global climate crisis increases temperatures in polar regions faster and with greater magnitude than elsewhere. The decline of Arctic sea ice opens up new passages, eventually leading to higher anthropogenic activities such as shipping, fishing, and mining. Climate change and anthropogenic activities will increase contaminant transport from temperate to Arctic regions. The shipping industry uses copper as an antifouling coating. Copper is an essential element but becomes toxic at excess concentrations, and its use may inadvertently affect non-target organisms such as copepods. Copper affects copepods by lowering reproductive output, prolonging developmental time, and causing increased mortality. As data on copper sensitivity of polar copepods at low temperatures are rare, we conducted onboard survival experiments with the Arctic region’s most common copepod species (Calanus finmarchicus, C. glacialis, C. hyperboreus). Acute survival tests were done for up to 8 days on individuals in 70 ml bottles at 1 °C with nominal copper concentrations ranging from 3 to 480 μg L−1. We used a reduced General Unified Threshold model for Survival (GUTS) to analyse the data, and placed our results in the context of the few published copper sensitivity data of the Antarctic and temperate copepod species at low temperatures. The sensitivity of Cu exposure was similar between the three Calanus species. However, a model comparison suggests that the tested C. glacialis population is less sensitive than the other two species in our experiments. Compared to published data, the three Arctic species appear slightly less sensitive to copper compared to their Antarctic counterparts but more compared to their temperate ones. Our literature search revealed only a few available studies on the copper sensitivity of polar copepods. In the future, this species group will be exposed to more pollutants, which warrants more studies to predict potential risks, especially given possible interactions with environmental factors.

Published: September 2024

Abstract
Context
There has been a limited amount of research which comparatively examines the local and landscape scale ecological determinants of the community structure of both riparian and aquatic bird communities in floodplain ecosystems.

Objectives
Here, we quantified the contribution of local habitat structure, land cover and spatial configuration of the sampling sites to the taxonomical and functional structuring of aquatic and terrestrial bird communities in a relatively intact floodplain of the river Danube, Hungary.

Methods
We used the relative abundance of species and foraging guilds as response variables in partial redundancy analyses to determine the relative importance of each variable group.

Results
Local-scale characteristics of the water bodies proved to be less influential than land cover and spatial variables both for aquatic and terrestrial birds and both for taxonomic and foraging guild structures. Purely spatial variables were important determinants, besides purely environmental and the shared proportion of variation explained by environmental and spatial variables. The predictability of community structuring generally increased towards the lowest land cover measurement scales (i.e., 500, 250 or 125 m radius buffers). Different land cover types contributed at each scale, and their importance depended on aquatic vs terrestrial communities.

Conclusions
These results indicate the relatively strong response of floodplain bird communities to land cover and spatial configuration. They also suggest that dispersal dynamics and mass-effect mechanisms are critically important for understanding the structuring of floodplain bird communities, and should therefore be considered by conservation management strategies.

Published: September 2024

AbstractUnderstanding and accurately reproducing the realistic response of rubber materials to external stimuli is a crucial research topic that involves all the engineering fields and beyond where these materials are used. This study introduces an innovative nonlinear fractional derivative generalized Maxwell model designed to effectively capture and replicate the experimental behavior of viscoelastic materials. The proposed model addresses the limitations observed in conventional fractional models, providing greater versatility which makes it more suitable for describing the intricate behavior of polymeric materials. Through rigorous mathematical validation, the proposed model demonstrates coherence with the underlying physics of the viscoelastic behavior. To address the identification procedure, the pole-zero formulation is adopted, employing a multi-objective optimization to obtain the optimum, able to replicate the dynamic moduli trends. Satisfying results have been validated over a wide dataset of 10 different materials, demonstrating an extended capability of adapting to different variations than classical widely-used fractional models. Furthermore, the model has proven to be valid even employing a reduced amount of experimental data limited only to low, high-frequency plateaus and around the glass transition temperature, which could be fundamental for optimizing resources in experimental investigations.

AbstractTobacco retail outlet (TRO) density has been associated with increased cotinine levels in pregnant persons and their children. As such, the higher densities of TROs may represent higher levels of active smoking during pregnancy. The purpose of this study is to simulate the reduction in cotinine (a biomarker of smoke exposure) and health care utilization that could occur in pregnant persons under enactment of several candidate TRO reduction policy recommendations. Using existing retail outlet data from the state of North Carolina and from the Newborn Epigenetic Study (NEST), the present study created hypothetical policy-informed datasets of TROs that a) limited the number of TROs to the same density as the 2014 San Francisco (SF) policy (Policy 1), b) set the minimum distance to 500 feet between TROs from a school and from other TROs (Policy 2), c) restricted the types of TROs to exclude pharmacies (Policy 3), and d) a combination of Policies 1–3 (Policy 4). We estimated the effects of each policy individually and in a separate model with their combined effects in terms of the reduction on cotinine levels and health care utilization, as measured by number of visits to the emergency department (ED). We found that the hypothetical policies were likely to be effective in reducing maternal cotinine and ED visits, with the majority of the mothers in the dataset demonstrating reductions in these outcomes after implementation of the policies. We found that Policy 1 led to moderate reductions in TRO exposure for the majority of the sample as well as stratified by race/ethnicity. Additionally, Policy 4 had slightly larger estimated effects than Policy 1, but could be more onerous to implement in practice. Overall, we identified evidence supporting the efficacy of TRO reduction strategies that could impact smoke exposure during pregnancy in our diverse sample in North Carolina.

Abstract
Purpose
Inborn errors of metabolism (IEM) are known with poor long-term health concerns; however, the health-related quality of life (HRQoL) and the burden placed on families remain unclear. This study investigated the self- and proxy-reported HRQoL of pediatric patients with IEM with or without developmental disabilities and the burden placed on their caregivers.

Methods
Patients with IEM aged 8–15 years and their caregivers were asked to respond to the Pediatric Quality of Life Inventory (PedsQL), EuroQoL five-dimension questionnaire for younger populations (EQ-5D-Y), and Japanese version of the Zarit Caregiver Burden Interview (J-ZBI). We compared EQ-5D-Y scores with matched EQ-5D-Y population norms. Intraclass correlation coefficients (ICC) for self and proxy HRQoL scores of those without developmental disabilities were calculated. Correlation coefficients of HRQoL proxy responses with J-ZBI score were estimated.

Results
We included 66 patients with IEM (mean age, 11.5 years; males, 41.2%) in the study. The mean (± standard deviation) EQ-5D-Y scores without and with developmental disabilities were 0.957 (± 0.071) and 0.821 (± 0.175), respectively. The EQ-5D-Y scores significantly increased compared with the reference values (p < 0.01, effect size = 0.337). The ICC values were 0.331 and 0.477 for the EQ-5D-Y and PedsQL scores, respectively. HRQoL proxy scores had strong negative correlations with J-ZBI scores.

Conclusion
The HRQoL of patients with IEM without developmental disabilities in our study was similar to that of the general Japanese population. The HRQoL of patients with IEM with developmental disabilities was low and associated with a tendency towards an increased burden of care.
Proportionality in Its Place: Weighted Internal Deliberation
Authors: Tanasoca Ana 
Published: September 2024

AbstractAccording to a well-known principle in democratic theory, all those whose interests are affected by a decision should have a say in it. ‘How much of a say?’ is the next question. One answer is the Proportionality Principle, according to which ‘people should have a say in a decision proportionally to the extent that their interests are affected by it’. It is often suggested that this principle should be implemented through weighted voting. This article considers an alternative: weighting as part of internal deliberation before the casting of votes. Instead of weighting votes as we count them, we could apply the Principle to the more fundamental process by which citizens form their judgements about how to vote. This alternative approach conceives of citizens as fulfilling dual roles: first, asclaim-makersadvancing claims about what the collective decision should be, basedinter aliaon how it impacts their own interests, and, second, asadjudicatorstaking into account everyone’s claim by weighing it proportionally to the degree each claimant is affected by the collective decision. I examine the democratic and epistemic strengths of this alternative as well as its weaknesses, compared to the more standard way of implementing the Proportionality Principle via weighted voting.

Published: September 2024

AbstractThe friction and wear characteristics of a-C:H:Si and a-C:H coatings in an ethanol environment at 120 °C and 10 MPa focusing on the effects of water and dissolved oxygen in ethanol were investigated. The friction tests were conducted using an autoclave chamber, with gases (oxygen or nitrogen) and ethanol–water mixtures (0 and 6 vol.%). The wear acceleration of a-C:H:Si took place when it slid in ethanol with 6 vol.% water and pressurized by oxygen, thus the specific wear rate was the highest, approximately 1.8 × 10−7 mm3/Nm. The reason of this wear acceleration was assumed the effect of hardness reduction due to oxidation of the a-C:H:Si, so the O/C ratio by AES and the hardness of topmost surface by AFM nano-scratch were investigated. As a result, the higher O/C ratio showed higher specific wear rate due to the hardness reduction from 13.3 to 6.0 GPa. These findings highlight the role of water and dissolved oxygen in accelerating wear of a-C:H:Si coatings.

AbstractMicrobially induced calcium carbonate precipitation (MICP) is recognized as an eco-friendly approach in biological chemistry, offering significant potential for enhancing soil engineering properties. This study investigates the viability of MICP for stabilizing washed recycled sands (RS) sourced from construction and demolition wastes, offering significant potential for enhancing soil engineering properties and aligning this research study with sustainable waste management practices. Through meticulously designed laboratory experiments, this research examined the micro and macro biomineralization processes to assess the feasibility and factors influencing RS stabilization. The experimental setup evaluates the impact of cementation media concentration, ambient temperature, treatment cycles, and curing time on MICP-treated RS efficiency. The findings indicate that the optimal MICP conditions can be found at a cementation media concentration of 0.5 mol/L, an ambient temperature of 30 °C, and furthermore, up to 12 treatment cycles can significantly enhance the unconfined compressive strength (UCS) of RS to 724 kPa. In addition, extending the curing time results in a 28% increase in UCS compared to the initial strength of MICP-stabilized RS. Analyses via scanning electron microscopy and X-ray diffraction provide insights into the microstructural and mineralogical transformations that aid the biostabilization of RS. This research underscores the effectiveness of MICP-treated RS for usage as a geomaterial, emphasizing its environmental and practical benefits and furthermore advocates the sustainable usage of MICP for the biostabilization of RS for construction activities.

AbstractIn this study, the effect of the Fe-rich intermetallic compound phases (IMC) on the solidification cracking susceptibility (Hot Tearing Susceptibility, HTS) of the Al–Mn–Cu alloy and the associated controlling factors were investigated. Using the Al–1.15Mn–1.0Cu–0.5Si–0.08Ti–0.016B–0.15Fe and Al–1.15Mn–1.0Cu–0.5Si–0.08Ti–0.016B–0.4Fe alloys, the HTS and mechanical properties in the partially solidified state were experimentally obtained. As a result, the HTS decreased with the increasing Fe contents. In addition, the tensile strength of the alloys in the partially solidified state (σmax) increased with the increasing Fe contents. The fraction of solid cohesion considering the Fe-rich IMC phase (fsc IMC) based on the Campbell’s model (fsc Campbell) is proposed as the controlling factor of σmax. The fsc Campbell, which simulates the two-phases model of the α-Al and liquid phases, did not consistently demonstrate the dependence of σmax on fsc Campbell for the two alloys (σmax = f(fsc Campbell)). However, when employing the fsc IMC, which incorporates the Fe-rich IMC phase in a three-phases model, a consistent correlation is observed between fsc IMC and σmax for the two alloys (σmax = f(fsc IMC)). Therefore, it is suggested that the controlling factor influencing the change in σmax with the Fe content should be the fsc IMC. Additionally, the bonding of primary α-Al phase together with Fe-rich IMC phase that is crystallized at the grain boundary will increase σmax, contributing to the reduction of HTS.
From net importer to global leader: understanding the drivers of Spain’s meat export growth since the 1960s
Authors: Delgado Pablo , Pinilla Vicente , Belloc Ignacio 
Published: September 2024

AbstractHow has Spain transitioned from historically having a relatively low meat production and being a net importer of meat in 1990 to becoming the world’s leading exporter of pork in 2020? This is the research question we aim to address in this article. In our quest for an answer, we constructed a gravity model to examine the determinants of Spanish meat exports. We posit that a significant surge in domestic meat consumption since the 1960s led to substantial economies of scale in the sector, rendering it highly competitive by the 1980s. Consequently, when Spain joined the European Union and liberalized the sector, it was sufficiently competitive to conquer international markets. In other words, we aim to study how a Home Market Effect has occurred in Spain and how it has been reinforced by the European Union adhesion. Ultimately, this high competitiveness has allowed Spain to capitalize on China’s demand for pork in recent years.

AbstractSystemic lupus erythematosus (SLE) is a chronic multifactorial autoimmune disease. It is now widely demonstrated that oxidative stress (OS) plays an important role in the modulation of the pathogenesis of this disease. Mitochondrial DNA (mtDNA) is highly vulnerable to OS and it is known a decrease of mtDNA copy number in SLE patients. However, to date, it has not been investigated if this decrease is associated with a dysregulation of mitochondrial homeostasis genes. Our aim is to evaluate the amount of mtDNA copy number and the expression of the genes more involved in the mitochondrial homeostasis pathways, in peripheral blood mononuclear cells (PBMCs) of SLE patients and healthy controls. We analysed the amount of mtDNA in PBMCs of 72 SLE patients and 61 healthy controls by qPCR. Then, we investigated the expression variability of TFAM and SIRT1 (biogenesis), MFN1 and MFF (fusion/fission) and PRKN2 (mitophagy) genes in a subgroup of SLE patients and healthy controls. Interestingly, we have observed a highly significant decrease in mtDNA copies in SLE patients compared to healthy controls (P < 0.0001). In addition, we have shown that the expression levels of SIRT1, MFN1 and PRKN2 genes were significantly decreased in SLE patients with respect to healthy controls (P = 0.00001 for SIRT1, P = 0.0150 for MFN1 and P = 0.0009 for PRKN2). Lastly, we have reported a positive correlation between PRKN2 expression level and mtDNA copy number (P = 0.019, r = 0.475). In conclusion, our data confirm the impairment of mtDNA copy number in the disease and show for the first time a dysregulation of the mitochondrial homeostasis genes. These results could provide additional support to the important role of mitochondria in SLE development.
Well Yes, but Actually No! Perceptions of Colombian Informal Workers About Venezuelan Immigration
Authors: Alizadeh Afrouzi Omid 
Published: September 2024

AbstractThis study explores the perceptions of Colombian sex workers, street vendors, and taxi drivers regarding Venezuelan immigration, its media coverage, and relevant NGO initiatives. Drawing on threat–benefit theory and mediated intergroup contact, short semi-structured and informal interviews were employed as the primary methodology. Findings showcase nuanced attitudes toward immigration, encompassing pros and cons. Informal workers faced downsides in job market, security, public services, housing, and conjugal relationships, yet acknowledged positive attitudes thanks to arrival of educated and cost-effective workforce, contribution to lifestyle, and perspective-taking. Views on media discourse and NGOs were mixed. Implications of results are discussed.
Sensory processing sensitivity, transliminality, and boundary-thinness as predictors of anomalous experiences, beliefs, and abilities
Authors: Roxburgh Elizabeth C. , Vernon David , Schofield Malcolm B. 
Published: September 2024

AbstractIndividual differences are among the most studied correlates of anomalous experiences and beliefs (AEs), but few have focussed on personality measures specifically defined by sensitivity. Of interest in this study is the personality trait of Sensory Processing Sensitivity (SPS), characterised by aesthetic sensitivity, being easily overwhelmed by internal and external stimuli, emotional reactivity and empathy, and deeper processing. An online survey investigated the relationship between SPS, and other personality constructs, in part, defined by sensitivity (transliminality and boundary-thinness) with anomalous experiences, beliefs, and abilities. Two hundred participants (mean age = 32.23; 151 females, 41 males, 6 non-binary and 2 preferred not to say) completed the Revised Transliminality Scale, the Boundary Questionnaire Short-Form, the Highly Sensitive Person Scale - Brief Version (measuring SPS), the Anomalous Experiences Inventory, and open-ended questions on SPS and AEs. There were significant and positive correlations between all four variables. Both transliminality and boundary thinness positively predicted anomalous beliefs with transliminality being the stronger, however, only transliminality predicted anomalous experiences and abilities. The findings suggest a relationship between SPS and anomalous experience and belief, but this is mediated by transliminality and boundary thinness.
Examining the Role of Family, Media, Peers in Young Caucasian Men’s Understandings of Body Dissatisfaction: A Thematic Analysis Using the Tripartite Influential Model and Social Comparison Theory
Authors: Apopei Daria , Coe Jennifer , Cordoba Sebastian 
Published: September 2024

AbstractThis study explores the factors contributing to body dissatisfaction among young Caucasian men. It focuses on family, peers, and media influences, addressing a gap in the literature that rarely integrates men’s experiences. The research draws on the Tripartite Influence Model and Social Comparison Theory, using thematic analysis to examine semi-structured interviews with eight participants aged 20–21. The research considers participants’ sexual orientation and country of origin when analysing the data. The findings show that family, peers, and the media positively and negatively shape body dissatisfaction among participants. Positive familial support can enhance body image, while negative comments from family members and peers exacerbate dissatisfaction. Social media was found to often reinforce unattainable body standards. The research contributes to the limited literature on men’s body dissatisfaction by expanding the application of the Tripartite Influence Model and Social Comparison Theory to this population. The study underscores the need for greater societal awareness and a more inclusive approach to body image research that considers diverse ethnic backgrounds and sexual orientations. We argue that more attention needs to be paid to men’s body dissatisfaction, as men are often excluded from these discussions. This study provides valuable insights into the dynamics of male body image, offering a foundation for future research and societal discourse on this often-overlooked issue.
