Authors: Tate Tanisha , Roberts Spencer , Main Luana C. , Bruce Lyndell 
Published: February 2025

SummarySleep is important for youth athletes, supporting sport‐related recovery and performance, as well as growth and development. Sleep may be influenced by training factors; therefore, this study aimed to characterise youth athletes' sleep, and examine associations between training load, schedule and frequency, and sleep. Twenty‐six youth basketballers (age: 14.22 ± 0.74 years, 13 male, 13 female) from a high‐performance sporting school were monitored for a period of 8 weeks. Sleep measures (via actigraphy and sleep diaries) were collected alongside training diaries (recording time, duration and perceived exertion). Youth athletes who finished training after 20:30 hours had significantly less total sleep time than when training finished before 20:30 hours. Higher daily total training duration was associated with decreased total sleep time. There is a potential contradiction with findings related to the number of sessions per day, as participants who completed two training sessions in a day had more sleep than those who completed one session per day; but this was not observed for athletes with three sessions per day. Participants had large intra‐individual variations (mean intra‐individual standard deviation) in bedtime (1.06 hr) and sleep time (0.84 hr). In conclusion: (1) late night training sessions appear to reduce total sleep time and should be avoided in youth athletes; (2) total daily training duration had a greater negative effect on sleep than session frequency; and (3) participants’ large intra‐individual variation in bedtime may reduce sleep quality and efficiency.
Determinants of Contribution Density to the Argentine Pension System: An Analysis by Cohorts, 1996–2021
Authors: Geri Milva , Villarreal Fernanda , Moscoso Nebel 
Published: February 2025

ABSTRACTContribution density is not the same as labor formality; it refers to the amount or proportion of contributions per worker that can be accumulated on average in a given period. The objective of this article is to identify the determinants of contribution density to the Argentine pension system from administrative data from 1996 to 2021. An econometric model is proposed to explain the contribution density in eight cohorts based on sociodemographic factors and job characteristics, using the negative binomial regression method. It is found that the density of contributions is low and depends on the branch of economic activity, the jurisdiction where the company is located, the individual's income and gender, and the age of enrollment. The results are similar to those found by other works that study contribution density in Argentina and Latin American countries.

ABSTRACTDuring periods of environmental change, genetic diversity in foundation species is critical for ecosystem function and resilience, but it remains overlooked in environmental monitoring. In the Baltic Sea, a key species for monitoring is the brown seaweed Fucus vesiculosus, which forms sublittoral 3D habitats providing shelter and food for fish and invertebrates. Ecological distribution models predict a significant loss of Baltic F. vesiculosus due to ocean warming, unless populations can adapt. Genetic variation and recombination during sexual reproduction are essential for adaptation, but studies have revealed large‐scale clonal reproduction within the Baltic Sea. We analysed genome‐wide single nucleotide polymorphism (SNP) data from the east Atlantic, the “Transition zone,” and the Baltic Sea, and found a mosaic of divergent lineages in the Baltic Sea, contrasting an outside dominance of a few genetic groups. We determined that the previously described endemic species Fucus radicans is predominantly a large female clone of F. vesiculosus in its northern Baltic distribution. In the two Estonian sites, however, individuals earlier referred to as F. radicans are sexually and reproductively isolated from Baltic F. vesiculosus, revealing a separate lineage that may have diverged long before the formation of the Baltic Sea. Monitoring Baltic Fucus without considering this genetic complexity will fail to prioritise populations with adaptive potential to new climate conditions. From our genomic data, we can extract informative and diagnostic genetic markers that differentiate major genetic entities. Such a SNP panel will provide a straightforward tool for spatial and temporal monitoring and informing management decisions and actions.

AbstractMany ectoparasite species serve as vectors for bacteria that are significant to both public and animal health, with wild, domestic and synanthropic mammals acting as reservoirs. However, limited information exists on the circulation and incidence of these vectors in Argentina. We examined the diversity, prevalence and abundance of ectoparasites, along with the presence of Rickettsia spp., of Didelphis albiventris Lund (Didelphimorphia, Didelphidae) within a rural landscape of the Pampas region, Argentina. We also analysed variations in ectoparasite populations concerning seasonality, livestock farm type and farmers' management practices. Seven species of hematophagous ectoparasites were collected, including mites (Mesostigmata, Laelapidae: Laelaps echidninus Berlese); ticks (Ixodida, Ixodidae: Ixodes loricatus Neumann); fleas (Siphonaptera, Rhopalopsyllidae: Polygenis platensis Jordan and Rothschild and Polygenis rimatus Jordan); Stephanocircidae: Craneopsylla minerva wolffhuegeli (Rothschild, Pulicidae: Ctenocephalides felis Bouché); and lice (Phthiraptera, Polyplacidae: Polyplax spinulosa Burmeister). Additionally, two bacteria were detected: Rickettsia felis Bouyer et al. (Rickettsiales, Rickettsiaceae) and Rickettsia sp. (Rickettsiales, Rickettsiaceae) were closely related to Rickettsia bellii Philip et al. (Rickettsiales, Rickettsiaceae). Fleas were the most prevalent and abundant group, with C. felis showing the highest values of mean abundance and prevalence. Parasitological comparisons between dairy farms and feedlots revealed similar results, with comparable densities of D. albiventris in both farm types. Ectoparasite abundance varied seasonally, peaking during the colder season. Regression analysis indicated higher ectoparasite infestation levels on farms with more dogs. The detection of pathogenic bacteria, coupled with the high prevalence and abundance of vectors, such as C. felis, suggests a significant epidemiological risk in the region. The commensal behaviour of D. albiventris facilitates it to thrive in areas modified by anthropogenic activity, positioning this species as a potential nexus between wild and domestic epidemiological cycles of parasites and emerging pathogens. Therefore, our findings suggest that D. albiventris plays a key role in the transmission and maintenance of ectoparasites and ectoparasite‐borne bacteria within these ecosystems.

AbstractBackgroundMissed nursing care (MNC) is a significant global issue in health care, especially in intensive care units (ICUs) where the complexity of patient care and high workloads increase the risk of errors and omissions. Nursing deficits impact patient safety, nurse efficiency and psychological well‐being, yet the relationship between ICU nurses' perceptions of patient safety, their caring behaviour, professional self‐efficacy and nursing deficits remains underexplored.AimThis study aimed to examine the relationships between ICU nurses' perceptions of patient safety, caring behaviour, professional self‐efficacy and nursing deficits through a multiple mediation model.Study DesignA cross‐sectional survey was conducted with 304 ICU nurses from general hospitals in Guangxi Province between January 2022 and January 2024. The study used validated instruments to measure patient safety perception, caring behaviour, professional self‐efficacy and nursing deficits. Spearman correlation and multiple mediation analyses were applied to explore the relationships among these variables.ResultsICU nurses reported average scores of 63.35 ± 8.06 for patient safety perception, 70.28 ± 12.14 for caring behaviour, 26.19 ± 4.57 for professional self‐efficacy and 75.92 ± 17.68 for nursing deficits. Significant negative correlations were found between patient safety perception, caring behaviour, professional self‐efficacy and nursing deficits (r = −.483, −.516, −.326, p < .01). Caring behaviour and self‐efficacy mediated the relationship between patient safety perception and nursing deficits, accounting for 74.65% of the total effect. This study follows the STrengthening the Reporting of OBservational studies in Epidemiology guidelines.ConclusionsThis study highlights that improving ICU nurses' perceptions of patient safety can reduce nursing deficits by enhancing caring behaviour and professional self‐efficacy, offering a pathway to improve care quality in ICUs.Relevance to Clinical PracticeHospital administrators should focus on strategies that enhance ICU nurses' safety perception, caring behaviour and self‐efficacy to reduce nursing deficits and improve patient outcomes.
Building microbial synthetic communities: get inspired by the design of synthetic plant communities

Published: February 2025

SummaryIn the last decade, the generation of host‐associated microbial culture collections has allowed the fine disentangling of complex relationships between commensal microbes and their hosts, and within‐microbiota interactions. Specifically, these culture collections have been used to construct microbial synthetic communities (SynComs), which allow the reconstruction of host microbiota in laboratory conditions. In three recent perspective publications, the importance of this tool has been highlighted, and the ground rules of utilization and designing of such SynComs have been laid out. It is important to note that although microbial SynComs are used to understand intricate ecological interactions occurring in natural conditions, the intraspecific genetic diversity present in natural microbial communities has been seldom considered in the design of interspecific microbial SynComs so far. In this Viewpoint, we therefore argue that designing microbial SynComs could benefit from recent developments in the design of synthetic plant communities, or plant SynComs. For instance, considering intraspecific plant genetic diversity and its effects on intra‐ and interspecific plant–plant interactions appears essential to better understand and predict highly productive and stable plant communities. Therefore, considering genetic diversity within microbial species undoubtedly represents an exciting opportunity to design innovative microbial SynComs.
Detecting Multiple Structural Breaks in Systems of Linear Regression Equations With Integrated and Stationary Regressors
Authors: Schweikert Karsten 
Published: February 2025

ABSTRACTIn this paper, we propose a two‐step procedure based on the group LASSO estimator in combination with a backward elimination algorithm to detect multiple structural breaks in linear regressions with multivariate responses. Applying the two‐step estimator, we jointly detect the number and location of structural breaks and provide consistent estimates of the coefficients. Our framework is flexible enough to allow for a mix of integrated and stationary regressors, as well as deterministic terms. Using simulation experiments, we show that the proposed two‐step estimator performs competitively against the likelihood‐based approach in finite samples. However, the two‐step estimator is computationally much more efficient. An economic application to the identification of structural breaks in the term structure of interest rates illustrates this methodology.

AbstractPurposeTo examine the developmental patterns of refractive error and optical components in hyperopic children with infantile (onset ≤12 months of age) accommodative or late‐onset (18–48 months of age) accommodative esotropia.MethodsThis prospective longitudinal study included children with infantile (n = 34) or late‐onset (n = 63) accommodative esotropia. Axial length (AL), anterior chamber depth (ACD), lens thickness (LT) and keratometry (K1, K2) were obtained with a Lenstar LS 900. Lenstar measures were recorded <6 months after cycloplegic spherical equivalent refraction (SER) was derived. An initial examination was conducted at 5.8 ± 1.5 years of age, with a follow‐up duration of 4.8 ± 0.8 years. A linear mixed‐effects model was used to estimate the rate of individual development for each ocular component and SER, and to compare the two groups.ResultsAll biometric components changed with age. The rates of change with age for SER and AL were significantly different between the infantile and late‐onset groups (SER: −0.18 vs. −0.12D/year, p < 0.001; AL: 0.16 vs. 0.14 mm/year, p < 0.01). The rate of change with age of the AL/CR ratio was significantly different between the infantile and late‐onset groups (0.019 vs. 0.016, p < 0.001). No significant differences in the rates of change in ACD, LT, K1 or K2 were identified.ConclusionsMajor ocular biometric components in children continue to mature in both infantile and late‐onset accommodative esotropia. Annual change in axial length is smaller in late‐onset accommodative esotropia than for infantile accommodative esotropia, consistent with less change in the SER with age.
Selection of Chickpea (Cicer arietinum L.) Genotypes Through a Combining of Tolerance Indices and Root Architecture: An Efficient Approach for the Identification of Drought‐Tolerant Genotypes

ABSTRACTChickpea is generally grown on marginal soils around the world, where it depends mainly on residual moisture. The recurrent scarcity of rainfall hampers production and reduces grain yields. In the face of this changing climate, genotypes with well‐developed root systems might contribute to stabilization of yield under drought conditions. So the fundamental aim of our study is to combine yield production performance with the attributes of a prolific root system in order to identify drought‐tolerant genotypes. Thus, a large collection of chickpeas (Desi and Kabuli) was evaluated following an augmented randomized complete block design (RCBD) in three trials: two in contrasting environments to assess grain yield and its components and one in the greenhouse to explore root architecture. The three indices, namely, stress tolerance index (STI), geometric mean productivity (GMP) and mean productivity (MP), are best suited to selecting tolerant genotypes. With their high heritability and genetic advance, traits such as plant height, number of pods/seeds, surface area, diameter and seed perimeter should be given particular attention by breeders under both normal rainfall and drought conditions. In addition, significant positive correlations were found between grain yield under stress and root length and number of lateral roots. The combination of salient results from the three trials led to the identification of 15 promising genotypes based on grain yield, phenology and root proliferation. In the face of increasing drought, this research not only makes these promising genotypes available for use in crossbreeding blocks and directly in the field but also provides important information for identifying genotypes resilient to drought‐stress regions.
The Crucial Roles of Phloem Companion Cells in Response to Phosphorus Deficiency

Published: February 2025

ABSTRACTMineral deficiency is a major problem in agriculture. Plant adaption to low mineral environments involves signaling between shoots and roots, via the food transport cells, the sieve elements. However, due to the sequestered position of the sieve elements in the vascular bundles, identifying shoot‐to‐root mobile signals is challenging. In herbaceous species, sieve elements and companion cells (CCs) are isolated from other leaf tissues. We hypothesize that phloem CCs play an essential role by synthesizing shoot‐to‐root signals in response to mineral deficiency. To test this hypothesis, we analyzed gene expression responses in Arabidopsis CCs under phosphorus deficiency using TRAP‐Seq. Phosphorus was chosen for its importance in plant growth and the known role of shoot‐to‐root signaling in regulating root phosphate transporters during deficiency. Our findings revealed that CCs exhibit more dramatic molecular responses than other leaf cells. We also found that many genes altered in CCs have potential functions in regulating root growth. This is unexpected because it has been widely believed that shoot‐to‐root signaling is not involved in root growth regulation under P deficiency. The importance of CCs in regulating mineral deficiency may extend beyond phosphorus because shoot‐to‐root signaling is a common response to the deficiency of various minerals.
Dependence and Fictional Characters
Authors: Chakravarty Shamik 
Published: February 2025

ABSTRACTThe artefactual theory of fiction holds that fictional characters are abstract and created artefacts like money and nations. One of its main proponents, Amie Thomasson, holds that fictional characters are ontologically dependent on a particular author or authors (rigid historical dependence) for their origin and on literary works for continued existence (generic constant dependence). While there have been objections to Thomasson's position, both the dependencies are dogmas held among artefactualists and the criticisms haven't yet systematically undermined them. In this paper, I argue against these two dependency claims by citing counterexamples, especially from a Twin Homer case, Fission Fiction case, No Man's Sky, a computer game, where an algorithm creates a character and in another instance, by showing how we humans actually create characters. If my arguments are sound, then a realist like Thomasson has no option to make sense of the data they set up for their theory apart from accepting Everett and Schroeder's theory that fictional characters are ideas. In the light of this, I set up a new criterion for the continued existence of fictional characters wherein they're ideas.

AbstractGlobal crop productivity is consistently threatened by cadmium (Cd) soil contamination. Crosstalk between nitric oxide (NO) and melatonin (MT) in enhancing crop resilience to heavy metal stress has gained significant attention. Here, we evaluated the joint effect of sodium nitroprusside (SNP; 200 μM as NO donor) and MT (100 μM) on Cd‐stressed eggplant (Solanum melongena L.). Cd stress significantly reduced plant growth, biomass yield, leaf pigments, and biochemical properties. Conversely, SNP, MT, and particularly their combined (SNP + MT) application reduced Cd toxicity and enhanced growth and physio‐biochemical traits of eggplants. For instance, at 50 mg Cd kg−1 soil, SNP, MT, and SNP + MT increased root biomass (41.6, 30, and 47%), total chlorophyll (30.7, 26.3, and 46%), soluble protein (20.5, 17.6 and 37%) and RLWC (23, 17.5, and 29%) over their respective control. Furthermore, SNP + MT significantly (p ≤ 0.05) reduced levels of EL, H2O2, proline, and MDA by 54.5, 66, 61 and 70%, respectively, in Cd‐stressed eggplants. SNP + MT interplay enhanced antioxidant defense responses in leaf tissues under Cd stress. Besides, SNP and MT upregulated transcript levels of POD, SOD, CAT, and GPX genes in eggplants under Cd stress. SNP and MT applications improved essential nutrient cation homeostasis in Cd‐stressed shoot tissues of eggplants. Moreover, SNP + MT lessens metal‐induced toxicity by decreasing Cd uptake, translocation (TF) and bioconcentration (BCF) factors. Conclusively, these findings validated the beneficial defensive interaction between SNP and MT in regulating Cd tolerance in eggplants. However, further research is needed to uncover the underlying defensive mechanisms of these synergistic effects.

Avicenna on the PSR and Causal Necessity in the Natural World
Authors: Richardson Kara 
Published: February 2025

ABSTRACTAvicenna's account of causal necessity in the natural world is a key part of his metaphysical system and it is also historically significant. Yet, there is little scholarly discussion of the philosophical basis of his view. This is surprising not only because the topic is important, but also because the view is challenging to interpret. Scholars frequently locate Avicenna's main defense of causal necessity in Metaphysics I.6.6 of The Book of Healing. A few look to Metaphysics II.1 of The Book of Salvation, where he seems to liken causal necessity to logical necessity using the example of fire's power to burn a suitable patient. In this paper, I maintain that neither of these arguments provides a satisfactory defense of the claim that causes necessitate their effects, or the related claim that natural bodies function as necessitating causes. In this paper, I examine a different Avicennian path to these claims, spanning Metaphysics IV.1 and Physics I.13 of The Book of Healing, which I call ‘the argument from the PSR’. I maintain that, through this argument, Avicenna makes his best case for causal necessity in the natural world.
