Complexity in Chick‐a‐Dee Calls of Mountain Chickadees (Poecile gambeli): Call Variation Associated With Flock Size and Flight
Authors: Selman Zaharia A. , Freeberg Todd M. 
Published: October 2024

ABSTRACTThe chick‐a‐dee call of chickadees, tits, and titmice is a vocal system used in a wide range of social contexts by both sexes throughout the year and is one of the more structurally complicated vocal systems outside of human language. Relatively little is known about the chick‐a‐dee calls of mountain chickadees, Poecile gambeli, however. This is an important species for increasing our comparative understanding of variation in chick‐a‐dee calls as they are one of the chickadee species with the largest naturally occurring flock sizes. Flock size relates to the social complexity of flocks, and the social complexity hypothesis for communication predicts that individuals in more complex social groups should communicate with greater complexity than individuals in simpler social groups. Correlational and experimental evidence in support of the hypothesis has been found in the calls of a wide range of species, including Carolina chickadees, P. carolinensis. Here, we provide the first description of the variation in note composition and note‐ordering rules in calls from mountain chickadee flocks in California and Colorado. California flocks were found to be significantly larger than Colorado flocks. Analysis of note‐type usage and transition probabilities between note types found that calls of California birds were more complex than calls of Colorado birds, supporting a key prediction of the social complexity hypothesis for communication. We also found relatively high rates of reversals of note‐ordering rules in mountain chickadee calls, which might help explain the complexity of the chick‐a‐dee calls of this species. Additionally, birds in flight produced calls with different note compositions when compared to perched birds. Generally, the note‐type ordering and transition probabilities of calls of mountain chickadees seem comparable to other better‐studied chickadee species, although their frequent note‐type order rule reversals suggest potential syntax‐like properties in this call system.

Published: October 2024

ABSTRACTMales often employ different reproductive tactics to gain access to females based on their condition and the surrounding environment. Predation risk is expected to have a significant influence on the frequencies of alternative reproductive tactics because these tactics typically differ in activity, which may result in differences in predation rate. In theory, such predation effects can explain the evolution as well as the maintenance of alternative reproductive tactics. Yet, there is little experimental work testing how predation risk affects alternative reproductive tactics. To assess such effects of predation, here we report on experiments with the two‐spotted spider mite Tetranychus urticae. The two‐spotted spider mite is a small arthropod herbivore species, in which males exhibit precopulatory mate guarding by mounting preadult moulting (and hence immobile) females. Two reproductive tactics are observed during mate guarding: The fighting tactic involves attacking other males to drive them away, while the sneaking tactic involves mounting the females and remaining motionless, even when contacted by other males. In this study, we exposed pairs of male and female spider mites to a predatory mite (Phytoseiulus persimilis) and observed their survival and male response to a predator when females were guarded by either fighter or sneaker males. We found that predation risk was not significantly different between fighter and sneaker males. However, the immobile females were more often preyed upon when guarded by sneakers than when guarded by fighters. We attribute this indirect effect of predation risk to the sneakers continuing to mount females even when a predator is nearby.

Published: October 2024

ABSTRACTThe deployment of large language models (LLMs) on edge devices and non‐server environments presents significant challenges, primarily due to constraints in memory usage, computational power, and inference time. This article investigates the feasibility of running LLMs across such devices by focusing on optimising memory usage, employing quantization techniques, and reducing inference time. Specifically, we utilise LLaMA 2 for biomedical text summarization and implement low‐rank adaptation (LoRA) quantization to compress the model size to compress the model size and fine‐tune it using limited resources. Our study systematically evaluates memory consumption during both training and inference phases, demonstrating substantial reductions through efficient LoRA quantization. Our results indicate that with careful optimization, it is feasible to deploy sophisticated LLMs like LLaMA 2 on low powered devices, thereby broadening the scope of their application in resource‐constrained environments.
Parent and adolescent perceptions of parent–child developmental relationships: The role of family routines

Published: October 2024

AbstractObjectiveThis study examined family routines in relation to the strength of parent–child developmental relationships and discordant perceptions among parents and their adolescent children.BackgroundPositive parent–child relationships and regular engagement in family routines are known to create a positive environment in which adolescents can thrive. Yet both parents and their children hold unique perspectives on family structure and functioning. Agreement between parent and child reports tend to be low and often become increasingly discrepant during adolescence. Engaging in consistent and predictable family routines may not only strengthen parent–child relationships but also result in more concordant perceptions of the quality of their shared relationship.MethodUsing data from 633 matched parents and their children, we examined the association between engagement in family routines and the strength of parent–adolescent relationships including discrepant reports using a latent congruence model.ResultsFamily routines were positively associated with stronger parent–adolescent relationships and less discrepant reports of this critical relationship.ConclusionEngagement in family routines plays an important role in parent–adolescent developmental relationships.ImplicationsFindings have important implications for practices and research focused on improving adolescent outcomes through family structures and parent–child relationships.
Fracture Analysis of 316L Specimens Fabricated via Material Extrusion Additive Manufacturing: Influence of Building Orientation and Notch Acuity
Authors: Spiller Saveria , Couto Sara , Razavi Nima 
Published: October 2024

ABSTRACTThree‐point bending tests were performed on notched specimens extracted from cuboids of 316L stainless steel produced via material extrusion additive manufacturing. The cuboids were printed vertically and horizontally on the printing platform to account for the building orientation effect on the mechanical performance. For each orientation, three notch sizes were considered. Overall, the specimens printed with building direction parallel to the loading direction outperformed the others. A significant notch size effect was observed in these specimens since the sharpest notch provoked a decrease in the peak load reached by the specimens in comparison with larger notches. On the contrary, this effect was less relevant among the other specimens, which presented a conspicuous amount of residual porosity that contributed to the premature failure. Further investigations were carried out to correlate the building orientation to the density of the parts and, ultimately, to the investigated mechanical properties. The ASED and TCD criteria were also applied to assess their accuracy in the failure prediction of the tested specimens.
Analysis of Fracture Modes and Acoustic Emission Characteristics of Low‐Frequency Disturbed Water‐Bearing Soft Rock With Different Cyclic Initial Value

Published: October 2024

ABSTRACTIn the complex geological environment of deep mining area, water‐bearing soft rock is more prone to damage and destruction by low‐frequency disturbance. In this paper, the dynamic–static combination test was conducted on the basis of uniaxial compression test by using creep dynamic disturbance impact loading system and acoustic emission technique. The test results show that with the increase of the initial value of disturbance loading, the fracture morphology of sandstone gradually changes from a single major crack to multiple cracks coexisting, and some saturated sandstones lose the bearing capacity in the process of disturbance, presenting a cone‐shaped fracture surface. The increase of the initial value of the disturbance changes the bearing capacity of the sandstone, and the peak energy of acoustic emission reaches the maximum value when the initial value of the disturbance is 80% UCS. The results of the study can provide some reference for the stability analysis of deep water‐rich soft rock mines.

ABSTRACTAimChanges in landscape configuration significantly impact ecosystems and the services they provide, including disease regulation for both humans and wildlife. Land use conversion usually favors disturbed‐adapted species, which are often known reservoirs of zoonotic parasites, thereby potentially escalating spillover events (i.e., the transmission of parasites to new hosts, including humans). Here we aimed to investigate how alterations in landscape use and configuration influence the distribution and co‐occurrence of potential hosts of zoonotic and epizootic parasites.LocationBrazilian Atlantic Forest.Time PeriodData collection spanned from 1997 to 2019.Major taxa studied small mammals.MethodsWe integrated ecological network metrics and joint distribution models while accounting for phylogenetic relationships and functional traits to answer two main questions: (1) do small mammal species considered central hosts in the transmission of parasites exhibit a higher probability of occurrence in landscapes with reduced native vegetation areas? (2) Do small mammal hosts that share a higher number of parasites have higher co‐occurrence probabilities?ResultsOur results demonstrated that species identified as significant hosts in our centrality network analysis displayed an increased probability of occurrence in landscapes that are both more fragmented and have a higher proportion of farming areas, hence fewer native vegetation areas. Regarding the relationship between species co‐occurrence and parasite sharing, our findings indicated that most strong co‐occurrences were prevalent within groups with higher parasite fauna similarity, but not all species sharing parasites had a higher probability of co‐occurring.ConclusionsHere we highlight the effects of landscape conversion on small mammal species, including how different configurations of land use can influence both central and non‐central host occurrences. Besides, our results also indicate that parasite transmission may be overestimated when the co‐occurrence probability of potential host species is not considered. We highly recommend incorporating co‐occurrence data to estimate zoonotic risk.
A critical appraisal of the International Classification of Headache Disorders migraine diagnostic criteria based on a retrospective multicenter cross‐sectional headache registry study in youth

Published: October 2024

AbstractObjectivesWe used Cluster Analysis of Migraine‐associated Symptoms (CAMS) to critically evaluate current International Classification of Headache Disorders‐Third Edition (ICHD‐3) migraine‐associated symptoms criteria.BackgroundDiagnostic criteria play a central role in guiding clinical trial inclusion, and therefore available treatments. Migraine and tension‐type headaches (TTH) are differentiated in ICHD‐3 by many headache characteristics, including associated symptoms. A diagnosis of probable migraine indicates some but not all features of migraine are met. Photophobia and phonophobia, or nausea and/or vomiting, are required to meet a diagnosis of migraine; however, CAMS—a model that describes associated symptoms across youth with headache—indicates that a broader range of symptoms contain information about migraine burden.MethodsIn this multisite retrospective cross‐sectional study, we evaluated ICHD‐3 migraine criteria. Youth aged 6–17 years with migraine (including probable migraine) or TTH were included in the analysis. We used CAMS to evaluate the migraine‐associated symptom criterion. With CAMS as a guide, we evaluated how changes to the migraine‐associated symptom criterion altered who met the diagnosis of migraine.ResultsOf the 9017 participants included in this study, 66.7% were female and had a median (interquartile range) age of 13 (10–15) years. Most participants had migraine or probable migraine (99.0%), and the remainder had TTH (1.0%). A sizable percentage (10.1%) of youth under the umbrella diagnosis of migraine were diagnosed with probable migraine because they did not meet migraine‐associated symptom criterion D; however, many in this group reported several non‐ICHD migraine‐associated symptoms. We explored alterations to criterion D based on CAMS. Allowing for photophobia or phonophobia re‐categorized 55.6% of youth as having migraine, though some only had one symptom. Including lightheadedness or lightheadedness and spinning re‐categorized 19.7% and 25.8% of youth with migraine, respectively, but all of those who were re‐categorized had at least two migraine‐associated symptoms.ConclusionThe ICHD‐3 captures the most prevalent migraine‐associated symptoms; however, many youths with probable migraine who do not meet full criteria due to insufficient associated symptoms nonetheless experience multiple non‐ICHD migraine‐associated symptoms. Changes to criterion D should be considered for the ICHD‐4.

Published: October 2024

ABSTRACTBackgroundWe investigated whether a novel 8‐week personalised health behaviour support programme, focusing on the stability of symptoms and strategies to improve activities of daily living, was feasible and acceptable in adults with post‐COVID syndrome.MethodsIn this randomised, controlled, pilot feasibility trial, 32 adults with post‐COVID syndrome (continued symptoms for ≥ 12 weeks) were randomised 1:1 to receive personalised health behaviour support (self‐reported physical activity and symptom diaries, plus seven one‐to‐one remotely delivered personalised self‐management support sessions), once weekly for 8‐weeks, or usual care (referral to online ‘your COVID‐19 recovery’ programme). The primary outcome was the feasibility of recruiting and randomising adults with post‐COVID syndrome. The secondary outcomes were to assess the acceptability and safety of the intervention and various outcome measures.ResultsOf the 48 adults who expressed interest in the study, 32 (67%) were eligible and completed the baseline assessment. All 32 adults were willing to be randomised to either the personalised health behaviour support programme (n = 17) or usual care (n = 15) and 27 (age: 45 ± 12 years) adults completed follow‐up at 9 weeks. The intervention was deemed feasible, with high adherence (92% and 94% completion rates for the physical activity and symptom diaries, respectively) and excellent acceptability rates (94% ‘liked the intervention a lot’). The intervention was deemed safe, with no symptom exacerbations reported.ConclusionAn 8‐week personalised health behaviour support programme was feasible for adults with post‐COVID syndrome, with good adherence and acceptability rates. Early pilot data from this small sample also suggests meaningful improvements in physical activity, fatigue and respiratory symptoms.Patient or Public ContributionPeople living with post‐COVID syndrome were involved from the outset with the study design, review of study documentation and interpretation of the data following completion. Furthermore, several participants have supported the local dissemination of findings following the completion of the study.
The lived experiences of the welfare state of platform workers: The barriers to accessing social protection in Italy, Sweden and the United Kingdom
Authors: Antonucci Lorenza 
Published: October 2024

AbstractThe recent literature on platform work and the welfare state has stressed that, despite being affected by high‐income insecurity, platform workers cannot easily access social protection. However, it is unclear why platform workers encounter such barriers. This article offers an inductive and empirically based theoretical framework to investigate the obstacles faced by platform workers. It shows that the barriers experienced by platform workers depend on the eligibility criteria, the assessment criteria and the trade‐off between taxation and social protection. The article substantiates these claims by offering both a policy analysis of formal arrangements and a qualitative analysis of the lived experiences of welfare of 101 platform workers in Italy, Sweden and the UK during COVID‐19. The research found that, while many platform workers attempted to access social protection during COVID‐19, platform workers' access to social protection was affected by their positionality as outsiders, which clashes with the eligibility criteria (in Sweden and Italy); by the irregular nature of platform work, which contrasts with the rigidity of the assessment criteria (in the UK, Italy and Sweden); and by the implicit trade‐off experienced by platform workers between minimising taxation and accessing to social protection (in the UK and Italy).
Interlaboratory study of flexural strength in additively manufactured alumina

Published: October 2024

AbstractWe report the results of an international interlaboratory study of the flexural strength of alumina fabricated across six laboratories using the vat photopolymerization ceramic additive manufacturing (AM) technology. The mechanical testing of all the specimens, 142 in total, was performed at the National Institute of Standards and Technology (NIST) according to the well‐established four‐point bending method standardized for traditional ceramics. Overall, the existing ASTM standard for the four‐point bend testing proved adequate for AM ceramics, with several modifications to the specimen requirements to account for the specifics of AM processes. Critical flaws that caused failure were identified in all but two cases using optical fractography augmented with the imaging of fracture surfaces in a scanning electron microscope. The flexural strength data, analyzed following the Weibull statistics, exhibited considerable variation among the specimen sets manufactured by different laboratories. This variability correlated with the presence of many distinct critical flaws. We identified seven types of flaws that accounted for the failure of 94% of specimens. The prevalent flaws depend on the printing direction relative to the specimen's geometry. We discuss the nature of these flaws and their relation to the printing and post‐processing conditions. Removal of several types of critical flaws will significantly improve mechanical properties of ceramic parts built using vat‐photopolymerization AM.
Purpose: A potential catalyst and anchor for optimal work–family balance and well‐being
Authors: Alexander Jamie D. , Harris Charlene , Durocher Stacie 
Published: October 2024

AbstractWorking parents often report difficulties in establishing optimal work–family balance, and such difficulties tend to yield poorer parent well‐being, parenting quality, and child well‐being. Despite advances in understanding of the long‐lasting and multifaceted benefits of purpose in life, up to this point, scant attention has been given to the concept of purpose as a practical means for promoting better parent well‐being and parenting quality, which also has far‐reaching impacts on child well‐being and trajectories. The goal of this paper is to discuss purpose as a potential catalyst and anchor for work–family balance and its associated outcomes of parenting well‐being, parenting quality, and child well‐being. Drawing from ecological systems, family systems, life course, and family resilience theories, this paper presents a conceptual model that depicts these relationships. Recommendations for advancing future research that supports theory building from this work as well as practice are provided.
Tradeoffs and synergy between material cycles and greenhouse gas emissions: Opportunities in a rapidly growing housing stock
Authors: Igdalov Sophia , Fishman Tomer , Blass Vered 
Published: October 2024

AbstractManagement of building materials’ stocks and flows is a major opportunity for circularity and de‐carbonization. We examine the relationship between material consumption and associated greenhouse gas (GHG) emissions under different scenarios in Israel, a developed country with an already high population density that expects tremendous growth in its housing stock by 2050. We created scenarios of varying housing unit sizes and additional material efficiency practices: fabrication yield, lifetime extension, material substitution, recycling, and their combination, resulting in 18 scenarios. In each scenario, the material flows and stocks needed to supply the housing demand and the resulting life‐cycle GHG emissions are quantified. No single material efficiency practice achieves a reduction in all indicators, suggesting a potential conflict between circular economy and decarbonization policies: The material substitution scenario allows for the biggest reduction in material consumption (12%–40% concrete reduction and 15%–51% steel reduction in 2050 compared with the baseline), while the recycling scenario achieves the biggest reduction in GHG emissions (22%–43% reduction in 2050 compared with the baseline). In the long‐term, the life‐extension scenario reduces most demolition waste. These findings can help policymakers and stakeholders consider the impacts of raw materials consumption and implement this knowledge in light of their priorities in policy packages. The results suggest a narrow window of opportunity within the next decade to influence material consumption and emissions to 2050. The findings could also shed light on the sustainability trajectories of other countries with similarly rapidly developing building stock, which have received little attention in this field.
