The effectiveness of a green default nudge in achieving resource conservation
Authors: González-Ramírez Jimena 
Published: May 2024

AbstractGreen nudges are used to promote conservation and pro-environmental behavior. This study examines the lasting effectiveness of a green default nudge in paper conservation, where price incentives are absent. At a private college in New York City, the default print setting was changed from single-sided to double-sided in Spring 2019, accompanied by a salient pop-up window that asked students to print double-sided. Analyzing student-level data over four semesters (Spring 2018 and Fall 2018 as control, Spring 2019 and Fall 2019 as treatment), this research contributes to the literature as it studies the effect of the nudge in the absence of pecuniary incentives. The findings support the hypothesis that this green default nudge was effective in promoting paper conservation and increasing resource efficiency. Results show that double-sided printing increased while single-sided printing decreased, leading to an overall reduction in paper usage. Employing a panel regression model with student fixed effects, this study finds that the nudge had a statistically significant effect in reducing the sheets per page ratio, and it improved the efficient use of paper by 19 percent. This inexpensive behavioral intervention proves successful in promoting environmental behavior and reducing paper consumption, which reduces greenhouse gas emissions.
Why are some people in the UK reluctant to seek support for their pets?
Authors: Muldoon Janine C , Williams Joanne M 
Published: May 2024

Abstract
Drawing upon data from a study examining experiences of accessing support for pets from the UK animal welfare charity Blue Cross, this paper illuminates reasons why people might not seek support when they need it. This applies to those who are struggling financially and are eligible for, but do not take, free/reduced cost veterinary care, or are having other problems (e.g. the animal’s disruptive behaviour or ill health, struggling to care for the pet due to changing circumstances or health problems, or coping with pet loss). Twenty Blue Cross service users (15 female, five male, age 29–67) took part in individual online interviews using a semi-guided narrative approach, where they were encouraged to share their experiences of reaching out. They were also asked to reflect upon why others may not do the same, and if they had any recommendations for organisations to help them reach these people. Findings echo other studies that highlight a fear of being judged, disclosure and stigma. Guilt, shame, lack of awareness, financial concerns, and wanting to manage independently, all play important roles. These factors have implications for the way support services are advertised and delivered to ensure animals receive the care needed. We describe these reflections and recommendations and identify three broader ideological narratives underpinning participants’ stories: ‘giving back’; ‘equity’, and ‘sacrifice’. These reveal how wider societal attitudes and values shape identities and behaviours. It is vital that support on offer is reframed to explicitly counteract these influences to ensure optimal animal and human welfare.

AbstractBackground:Understanding characteristics of healthcare personnel (HCP) with SARS-CoV-2 infection supports the development and prioritization of interventions to protect this important workforce. We report detailed characteristics of HCP who tested positive for SARS-CoV-2 from April 20, 2020 through December 31, 2021.Methods:CDC collaborated with Emerging Infections Program sites in 10 states to interview HCP with SARS-CoV-2 infection (case-HCP) about their demographics, underlying medical conditions, healthcare roles, exposures, personal protective equipment (PPE) use, and COVID-19 vaccination status. We grouped case-HCP by healthcare role. To describe residential social vulnerability, we merged geocoded HCP residential addresses with CDC/ATSDR Social Vulnerability Index (SVI) values at the census tract level. We defined highest and lowest SVI quartiles as high and low social vulnerability, respectively.Results:Our analysis included 7,531 case-HCP. Most case-HCP with roles as certified nursing assistant (CNA) (444, 61.3%), medical assistant (252, 65.3%), or home healthcare worker (HHW) (225, 59.5%) reported their race and ethnicity as either non-Hispanic Black or Hispanic. More than one third of HHWs (166, 45.2%), CNAs (283, 41.7%), and medical assistants (138, 37.9%) reported a residential address in the high social vulnerability category. The proportion of case-HCP who reported using recommended PPE at all times when caring for patients with COVID-19 was lowest among HHWs compared with other roles.Conclusions:To mitigate SARS-CoV-2 infection risk in healthcare settings, infection prevention, and control interventions should be specific to HCP roles and educational backgrounds. Additional interventions are needed to address high social vulnerability among HHWs, CNAs, and medical assistants.

Published: May 2024

AbstractWe evaluated sampling and detection methods for fungal contamination on healthcare surface materials, comparing the efficacy of foam sponges, flocked swabs, and Replicate Organism Detection And Counting (RODAC) plates alongside culture-based quantification and quantitative polymerase chain reaction (qPCR). Findings indicate that sponge sampling and qPCR detection performed best, suggesting a foundation for future studies aiming to surveillance practices for fungi.
Effect of thermal fluctuations on spectra and predictability in compressible decaying isotropic turbulence
Authors: Ma Qihan , Yang Chunxin , Chen Song , Feng Kaikai , Cui Ziqi , Zhang Jun 
Published: May 2024

This study investigates the impact of molecular thermal fluctuations on compressible decaying isotropic turbulence using the unified stochastic particle (USP) method, encompassing both two-dimensional (2-D) and three-dimensional (3-D) scenarios. The findings reveal that the turbulent spectra of velocity and thermodynamic variables follow the wavenumber (k) scaling law of

${k}^{(d-1)}$

for different spatial dimensions

$d$

within the high wavenumber range, indicating the impact of thermal fluctuations on small-scale turbulent statistics. With the application of Helmholtz decomposition, it is found that the thermal fluctuation spectra of solenoidal and compressible velocity components (

${\boldsymbol {u}}_{s}$

and

${\boldsymbol {u}}_{c}$

) follow an energy ratio of 1 : 1 for 2-D cases, while the ratio changes to 2 : 1 for 3-D cases. Comparisons between 3-D turbulent spectra obtained through USP simulations and direct numerical simulations of the Navier–Stokes equations demonstrate that thermal fluctuations dominate the spectra at length scales comparable to the Kolmogorov length scale. Additionally, the effect of thermal fluctuations on the spectrum of

${\boldsymbol {u}}_{c}$

is significantly influenced by variations in the turbulent Mach number. We further study the impact of thermal fluctuations on the predictability of turbulence. With initial differences caused by thermal fluctuations, different flow realizations display significant disparities in velocity and thermodynamic fields at larger scales after a certain period of time, which can be characterized by ‘inverse error cascades’. Moreover, the results suggest a strong correlation between the predictabilities of thermodynamic fields and the predictability of

${\boldsymbol {u}}_{c}$

Lexicographic Preferences in Candidate Choice. How Party Affiliation Dominates Gender and Race
Authors: Hjortskov Morten , Andersen Simon Calmar 
Published: May 2024

AbstractUnderstanding which political candidates are elected for office is fundamental to democracy and political science. Whereas there is much agreement that party affiliation is one of the most important candidate characteristics to voters, evidence regarding the gender and race of the candidate is mixed. We suggest voters have lexicographic preferences, meaning they rank their preferences and focus primarily on the candidate's party affiliation. Second-order preferences such as gender and race are mostly necessary when there is a tie in first-order preferences when voters choose between two same-party candidates or have no party information. We show how conjoint experiments can be used to test for lexicographic preferences and use data from a US-representative sample and a pre-registered replication to confirm that in the United States, gender and race are second-order preferences. Lexicographic preferences provide a theoretical lens explaining some of the mixed results of gender and race in the candidate literature.

AbstractDengue fever is a viral disease caused by one of four dengue stereotypes (Flavivirus: Flaviviridae) that are primarily transmitted by Aedes albopictus (Skuse) and Aedes aegypti (L.). To safeguard public health, it is crucial to conduct surveys that examine the factors favouring the presence of these species. Our study surveyed 42 councils across four towns within the Bhakkar district of Punjab Province, by inspecting man-made or natural habitats containing standing water. First, door-to-door surveillance teams from the district health department were assigned to each council to surveillance Aedes species and dengue cases. Second, data collection through surveillance efforts, and validation procedures were implemented, and the verified data was uploaded onto the Dengue Tracking System by Third Party Validation teams. Third, data were analysed to identify factors influencing dengue fever cases. The findings demonstrated the following: (1) Predominantly, instances were discerned among individuals who had a documented history of having travelled beyond the confines of the province. (2) Containers associated with evaporative air coolers and tyre shops were responsible for approximately 30% of the Aedes developmental sites. (4) Variability in temperature was responsible for approximately 45% of the observed differences in the quantity of recorded Aedes mosquito developmental sites. (5) Implementation of dengue prevention initiatives precipitated a 50% reduction in Aedes-positive containers, alongside a notable 70% decline in reported cases of dengue fever during the period spanning 2019 to 2020, while the majority of reported cases were of external origin. Aedes control measures substantially curtailed mosquito populations and lowered vector-virus interactions. Notably, local dengue transmission was eliminated through advanced and effective Aedes control efforts, emphasising the need for persistent surveillance and eradication of larval habitats in affected regions.
Opinion formation on evolving network: the DPA method applied to a nonlocal cross-diffusion PDE-ODE system
Authors: Fagioli Simone , Favre Gianluca 
Published: May 2024

AbstractWe study a system of nonlocal aggregation cross-diffusion PDEs that describe the evolution of opinion densities on a network. The PDEs are coupled with a system of ODEs that describe the time evolution of the agents on the network. Firstly, we apply the Deterministic Particle Approximation (DPA) method to the aforementioned system in order to prove the existence of solutions under suitable assumptions on the interactions between agents. Later on, we present an explicit model for opinion formation on an evolving network. The opinions evolve based on both the distance between the agents on the network and the ’attitude areas’, which depend on the distance between the agents’ opinions. The position of the agents on the network evolves based on the distance between the agents’ opinions. The goal is to study radicalisation, polarisation and fragmentation of the population while changing its open-mindedness and the radius of interaction.
Tradition counts. The boom in the Spanish broiler chicken and pork sectors, 1955–2020
Authors: Clar Ernesto 
Published: May 2024

AbstractThe economic success of the intensive poultry and pork sectors is a milestone in the Spanish economic history of the past seven decades. This work analyses the boom in the chicken and pork businesses in Spain, verifying the strengths and weaknesses of both livestock models, and drawing conclusions in relation to the agribusiness system. The influence of chicken and pork in the booming Spanish meat sector is analysed from the perspectives of livestock farming and agroindustry, followed by the impact of both forms of intensive livestock farming on Spain’s domestic consumption and foreign trade. The similarities and differences in their evolution are identified from the perspective of two food supply models: a predominance of economies of scale until the 1980s, and of so-called economies of scope since that time. While the development of mass production in both intensive livestock businesses followed a similar pattern, the progressive segmentation of the market towards higher quality, more artisanal and sustainable products has greatly favoured the sector more deeply rooted in rural tradition: pork.

Summary
Understanding the movement ecology of threatened species is fundamental to improving management and conservation actions for their protection, mainly during the pre-adult stage and particularly when a species is subject to population reinforcement or reintroduction projects. An example is the case of the Cinereous Vulture Aegypius monachus on the Iberian Peninsula, an endangered species that has been reintroduced in different regions during the last two decades. Here, we explore differences between the spatial ecology of reintroduced pre-adult Cinereous Vultures, according to age-class, sex, and season (breeding and non-breeding). We used GPS-tag data from 51 pre-adult individuals reintroduced into Catalonia (north-east Spain) to describe their use of space, i.e. home-range size, core area, and minimum convex polygon (MCP) and movement patterns, i.e. cumulative distance, maximum displacement, maximum daily dispersal, and maximum annual dispersal. Our study showed significant variation in the use of space and movement patterns among pre-adult birds and the influences of age, sex, and season. Age was the most influential factor, determining range areas and movement patterns. Similar to other vulture species, home range and core areas increase with age, with subadult vultures exhibiting larger ranges than young first year, juveniles, and immature birds, but the MCP measures were larger for juveniles. Movement patterns were also influenced by age-class, with juveniles making longer movements, followed by immatures and subadults (with similar values), and shorter movements for birds during their first year of life. Overall, males made shorter movements and explored smaller foraging areas than females. Season had an important effect on movement patterns, and the daily and dispersal movements were longer during the breeding period (February–August). Our findings fill a knowledge gap regarding the dispersal behaviours of Cinereous Vultures, information that will enable the improvement of management and conservation decisions.
Bonus-Malus Scale premiums for Tweedie’s compound Poisson models
Authors: Boucher Jean-Philippe , Coulibaly Raïssa 
Published: May 2024

AbstractBased on the recent papers, two distributions for the total claims amount (loss cost) are considered: compound Poisson-gamma and Tweedie. Each is used as an underlying distribution in the Bonus-Malus Scale (BMS) model. The BMS model links the premium of an insurance contract to a function of the insurance experience of the related policy. In other words, the idea is to model the increase and the decrease in premiums for insureds who do or do not file claims. We applied our approach to a sample of data from a major insurance company in Canada. Data fit and predictability were analyzed. We showed that the studied models are exciting alternatives to consider from a practical point of view, and that predictive ratemaking models can address some important practical considerations.
Widening the gap of political inequality? The effect of the COVID-19 pandemic on political engagement
Authors: Belchior Ana Maria 
Published: May 2024

AbstractThere is extensive evidence that the COVID-19 pandemic has mostly affected the less well-off in society, boosting economic inequality. In contrast, little is known about how much such rising economic disparities affected the involvement of individuals in politics, thereby enhancing political inequality. Extending the research on political inequality to a key and somewhat neglected dimension of citizens’ involvement with politics - political engagement - this article claims that the COVID-19 depressed engagement and promoted political inequality. The analysis relies on a comparative European approach and on data before and after the emergence of the pandemic. Besides generally finding an overall socioeconomic gap with regard to political engagement, results also suggest that the pandemic somewhat lessened engagement, increasing the gap between the more and less socioeconomically advantaged. Generally, this is not strictly due to a tendency to decrease engagement among the latter but also to increase engagement among the former.

Published: May 2024

AbstractThis study investigates natural hydrogen (H2) occurrences in the Paris Basin, using Optical Character Recognition (OCR) technology to analyze an extensive, yet underexploited, database that contains historic drilling records. The potential of natural hydrogen has been largely unexplored in conventional oil and gas wells. Utilizing the in‐house CVAGeoDB database based on public well data, which includes well logs, mudlogs, and End Drilling Reports (EDRs) in PDF image format, we applied the Tesseract‐OCR Engine to convert these documents into searchable formats for efficient data analysis. Our analysis revealed several H2‐bearing wells across French sedimentary basins. The hydrogen occurrences in the Aquitaine Basin may be explained by the geological context and in particular the presence of a mantle body at shallow depth. On the contrary, the detection of H2 in the Paris Basin cannot be explained in a straightforward manner as the presence of ultramafic or U‐rich rocks is poorly documented so far. In the Paris Basin, H2 has been detected in four main formations: the Lusitanian, the Dogger, and Triassic aquifers as well as in the basement. The highest hydrogen concentration (52 vol%) was measured in the Dogger aquifer. These wells are primarily located along the Bray Fault, indicating at least a structural influence on H2 distribution. Finaly, the presence of serpentinzed dunite from the Lizard complex associated with the bedrock may have played the role as a source for H2. This research demonstrates the effectiveness of OCR in reassessing historical drilling data for natural hydrogen exploration, highlighting the need for comprehensive exploration methodologies in this emerging field.

AbstractNeighbourhood disadvantage may be associated with brain health but the importance of exposure at different stages of the life course is poorly understood. Utilising the Lothian Birth Cohort 1936, we explored the relationship between residential neighbourhood deprivation from birth to late adulthood, and global and local neuroimaging measures at age 73. A total of 689 participants had at least one valid brain measures (53% male); to maximise the sample size structural equation models with full information maximum likelihood were conducted. Residing in disadvantaged neighbourhoods in mid- to late adulthood was associated with smaller total brain (β = −0.06; SE = 0.02; sample size[N] = 658; number of pairwise complete observations[n]=390), grey matter (β = −0.11; SE = 0.03; N = 658; n = 390), and normal-appearing white matter volumes (β = −0.07; SE = 0.03; N = 658; n = 390), thinner cortex (β = −0.14; SE = 0.06; N = 636; n = 379), and lower general white matter fractional anisotropy (β = −0.19; SE = 0.06; N = 665; n = 388). We also found some evidence on the accumulating impact of neighbourhood deprivation from birth to late adulthood on age 73 total brain (β = −0.06; SE = 0.02; N = 658; n = 276) and grey matter volumes (β = −0.10; SE = 0.04; N = 658; n = 276). Local analysis identified affected focal cortical areas and specific white matter tracts. Among individuals belonging to lower social classes, the brain-neighbourhood associations were particularly strong, with the impact of neighbourhood deprivation on total brain and grey matter volumes, and general white matter fractional anisotropy accumulating across the life course. Our findings suggest that living in deprived neighbourhoods across the life course, but especially in mid- to late adulthood, is associated with adverse brain morphologies, with lower social class amplifying the vulnerability.
