Education-to-work transition among war-affected youth in post-conflict settings is fraught with challenges, not least compounded by the little attention placed on individual agency and mental health. This review examines the debate on war-affected youth skilling programmes in post-conflict settings, which neglect the roles of individual agency and mental health in the education-to-work transition. Building on Albert Bandura’s Self-Efficacy Theory (SET) and the Cumulative Stress Hypothesis (CSH), the review presents an integrated approach to skills development for improving education-to-work transition among war-affected youth. According to SET, the development of self-efficacy is anchored on enactive mastery, vicarious experience, verbal persuasion, and physiological arousal. Moreover, individual agency factors such as motivation, aspiration, goal orientation, active efforts, and alignment of intentions with skills are protective factors for effective education-to-work transition, but they are also eroded by the adverse consequences of violent conflicts. Similarly, the CSH also suggests that the effects of exposure to protracted violent conflicts are cumulative and may lead, in turn, to a plethora of mental health problems in the aftermath of violent conflicts. Mental health problems like depression, anxiety, and PTSD are linked to, inter alia, behaviours such as aggression, substance abuse, and apathy, all related to poor employment outcomes. To increase the employability of young people affected by war, skills training institutions and work settings need to prioritise the mental health and individual agency of the youth, as well as skills acquisition for specific trades. Consequently, we propose an integrated model of reintegrating war-affected and vulnerable youth anchored on professional technical and vocational skills training; recognition of individual agency; provision of mental and psychosocial support; and life skills training, all nested within the local economic realities.

Background/Objectives: Inappropriate use of emergency department (ED) services is widely acknowledged to have a negative impact on health systems as a whole. A minor portion of Frequent User (FU) patients are often responsible for the disproportionate use of ED services. Methods: A retrospective population study was conducted on the attendances of pediatric EDs from 1 January 2022 to 31 December 2022 at the Roma 1 Local Health Authority in Rome, a territory served by more than 13 EDs. Nested logistic regression analysis was used to investigate patient characteristics in predicting inappropriate use of EDs. Results: In 2022, 35,691 pediatric ED attendances were recorded, with 24,824 patients distributed among 904 PCP/GPs in the six districts. A total of 71.8% of patients had only one attendance in 2022. A total of 3.5% of the patients were FUs, who were responsible for more than 10% of the attendances. However, most of the attendances were not appropriate. FUs, younger age (<2 yo), and more severe clinical presentations were more likely to be associated with appropriate ED attendance. PCPs/GPs and districts do not have a role in determining a higher number of ED attendances. The single patient’s characteristics have a greater influence on this phenomenon. Conclusions: Frequent use of the ED is not associated with inappropriate use among children, mainly due to the characteristics and needs of specific patients. However, parents’ education for a more rational use of health system resources and the provision of local solutions to children’s health needs may allow for a more appropriate use of health service resources.

The nesting of Passaloecus pictus Ribaut, 1952 was observed in Kowalewo Pomorskie (northern Poland). The nests were built in trap nests that were placed on a windowsill facing southwest. The females used resin from Picea pungens Engelm., located 5 m away, to build the cell walls. The tunnel consisted of 1–7 cells. The females provided provisions for two to three cells per day. The frequency with which a female brought aphids to a nest cell varied from 1 to 7 min. No males were observed near the nest. A total of 42 cells were examined (consisting of 31 female cells and 11 male cells). On average, a female brought about 33 aphids to the female cells and 21 aphids to the male cells. The prey were Macrosiphoniella millefolii (De Geer, 1773), Dysaphis crataegi (Kaltenbach, 1843), Macrosiphoniella persequens (Walker, 1852) and Uroleucon achilleae (Koch, 1855). The nest parasites were Melittobia acasta (Walker, 1839). The occurrence of a second generation has been confirmed. Full article

Identifying urban functional zones is one of the important foundational activities for urban renewal and the development of high-quality urban areas. Efficient and accurate identification methods for urban functional zones are significant for smart city planning and industrial layout optimization. However, existing studies have not adequately considered the impact of the interactions between human activities and geographical space provision on the delineation of urban functional zones. Therefore, from the perspective of integrating the spatiotemporal characteristics of human activities with the distribution of urban functional facilities, by incorporating mobile signaling, POI (point of interest), and building outline data, we propose a multifactorial weighted kernel density model that integrates ‘human activity–land feature area–public awareness’ to delineate urban functional zones quantitatively. The results show that the urban functional zones in the central city area of Lanzhou are primarily characterized by dominant single functional zones nested within mixed functional zones, forming a spatial pattern of ‘single–mixed’ synergistic development. Mixed function zones are widely distributed in the center of Lanzhou City. However, the area accounted for a relatively small proportion, the overall degree of functional mixing is not high, and the inter-district differences are obvious. The confusion matrix showed 85% accuracy and a Kappa coefficient of 0.83. Full article

Graph query languages such as Cypher are widely adopted to match and retrieve data in a graph representation, due to their ability to retrieve and transform information. Even though the most natural way to match and transform information is through rewriting rules, those are scarcely or partially adopted in graph query languages. Their inability to do so has a major impact on the subsequent way the information is structured, as it might then appear more natural to provide major constraints over the data representation to fix the way the information should be represented. On the other hand, recent works are starting to move towards the opposite direction, as the provision of a truly general semistructured model (GSM) allows to both represent all the available data formats (Network-Based, Relational, and Semistructured) as well as support a holistic query language expressing all major queries in such languages. In this paper, we show that the usage of GSM enables the definition of a general rewriting mechanism which can be expressed in current graph query languages only at the cost of adhering the query to the specificity of the underlying data representation. We formalise the proposed query language in terms declarative graph rewriting mechanisms described as a set of production rules $L\to R$ while both providing restriction to the characterisation of L, and extending it to support structural graph nesting operations, useful to aggregate similar information around an entry-point of interest. We further achieve our declarative requirements by determining the order in which the data should be rewritten and multiple rules should be applied while ensuring the application of such updates on the GSM database is persisted in subsequent rewriting calls. We discuss how GSM, by fully supporting index-based data representation, allows for a better physical model implementation leveraging the benefits of columnar database storage. Preliminary benchmarks show the scalability of this proposed implementation in comparison with state-of-the-art implementations. Full article

Hyperprolific sows often experience increased oxidative stress during late gestation and lactation periods, which can adversely affect the farrowing process and overall lactation performance. This study examines the influence of providing a coconut coir mat (CCM; 1 × 1 m) as nesting material, supplementing high-dose vit-C (HVC; 20% vit-C, 10 g/kg feed) as an antioxidant, or both on maternal behavior, the farrowing process, oxidative status, cortisol levels, and preovulatory follicle developments in sows with large litters. In total, 35 sows (Landrace × Yorkshire; litter size 15.43 ± 0.27) were allocated to the following four treatment groups: control (n = 9, basal diet), vit-C (n = 8, basal diet + HVC), mat (n = 10, basal diet + CCM), and mat + vit-C (n = 8, basal diet + HVC + CCM). A post-hoc analysis showed that compared with sows that were not provided CCM, mat and mat + vit-C groups demonstrated increased durations of nest-building behavior during the period from 24 h to 12 h before parturition (p < 0.05 for both), reduced farrowing durations, and decreased intervals from birth to first udder contact (p < 0.01 for both). The mat group exhibited lower advanced oxidation protein product (AOPP) levels during late gestation and lactation periods than the control group (p < 0.05). Sows with HVC supplementation showed longer farrowing durations than those without HVC supplementation (p < 0.0001). The vit-C group had higher salivary cortisol levels on day 1 after farrowing than the other treatment groups (p < 0.05). Furthermore, the follicle diameters on day 3 after weaning in the vit-C group tended to be smaller than those in the control group (p = 0.077). HVC supplementation prolonged farrowing and increased the physiological stress on postpartum, and no advantageous effects on maternal behavior and developmental progression of preovulatory follicles were observed. Hence, alternative solutions beyond nutritional approaches are required to address increased oxidative stress in hyperprolific sows and secure their welfare and reproductive performance. The present results substantiated the positive impact of providing CCM as nesting material for sows with large litters on nest-building behavior and the farrowing process, which could mitigate the deleterious consequences induced by peripartum physiological and oxidative stress.

The loss of mature forests is a known stressor of forest management on biodiversity. Mature forests provide unique habitat for forest birds. Here, we examine the capacity of mature forest stands embedded in an intensively managed landscape to provide habitat for landbird species that are associated with mature, unfragmented habitats. We carry this out by comparing bird communities in forest stands in three landscapes with a gradient of management activity. We examined community-level indicators (richness, diversity, abundance and community structure), and trait-level indicators (species groups associated with cavity nesting, mature forests, interior forests and area sensitivity). We found no obvious negative effects on bird communities, species and trait groups in forest stands in the most intensively managed landscape relative to the less intensively managed landscapes. Our ability to draw inferences about the influence of management intensity is limited due to lack of replication; however, these results do provide evidence that mature forest stands within intensively managed landscapes can provide valuable habitat to mature forest associates. There are often trade-offs between generating wood products from the forest and the provision of mature forest habitats. Research on forest birds can provide some of the necessary information for assessing the size and shape of those trade-offs and help to inform the conversation about the desired structure, function and composition of forests.

Nestboxes are commonly used to increase the number and quality of nest sites available to birds that usually use tree cavities and are considered an important conservation intervention. Although usually safer than natural cavities, birds nesting in simple, unmodified wooden nestboxes remain at risk of depredation. Accordingly, numerous design and placement modifications have been developed to ‘predator-proof’ nestboxes. These include: (1) adding metal plates around entrance holes to prevent enlargement; (2) affixing wire mesh to side panels; (3) deepening boxes to increase distance to nest cup; (4) creating external entrance ‘tunnels’ or internal wooden ledges; (5) using more robust construction materials; (6) developing photosensitive shutters to exclude nocturnal predators; (7) using baffles to block climbing mammals; and (8) regular replacement and relocation. However, the benefits and costs of these modifications are not always well understood. In this global review, we collate information on predator-proofing avian nestboxes designed for tree cavity-nesting birds to assess the efficacy of techniques for different predators (mammalian, avian, and reptilian) in different contexts. We critique the potential for modifications to have unintended consequences—including increasing nest building effort, altering microclimate, reducing provisioning rate, and elevating ectoparasite and microbial loads—to identify hidden costs. We conclude by highlighting remaining gaps in knowledge and providing guidance on optimal modifications in different contexts. Full article

This study investigates the impact of two years of emergency distance schooling on achieving Sustainable Development Goal (SDG) 4—equitable quality education, both globally and in Kazakhstan. The study used a qualitative research design. Individual semi-structured interviews were conducted with 30 teachers and 30 parents, while focus group discussions (FGDs) were utilised to gather the perspective of 28 students. The conceptual framework developed puts effective pedagogy at the heart of quality distance education, nested within four supportive factors—digital infrastructure; policy guidelines about pedagogy; curriculum and assessments; professional development in digital pedagogy; and the home environment. The study found that distance schooling in Kazakhstan has undermined progress on SDG 4 and worsened inequalities in access to quality education despite the distribution of digital devices to disadvantaged children and teachers. While mainstream public school teachers transitioned to distance school without any systematic preparation, provision of digital resources or clear policy guidelines, schoolteachers at elite public institutions received meticulous guidance and support. Despite later receiving professional development in digital pedagogy and access to digital resources and platforms, public school teachers in rural and deprived urban areas still faced challenges due to fragmented internet connectivity. This limited interactive and communicative pedagogy, particularly in rural and public schools, and hindered teachers’ ability to assess the impact of their teaching on student outcomes. Policy initiatives failed to mitigate disadvantages in the home environment for low-income families, parents with limited education and working parents, especially mothers, who primarily supported homeschooling. Recommendations are offered for adapting education provision and envisioning more robust education quality to achieve SDG 4 and address historical inequities in a post-pandemic world. Full article

The brood reduction hypothesis, which explains asynchronous hatching in birds, as an adaptation that enables selective survival of older nestlings when availability of food is unpredictable. This study was conducted in order to determine whether the brood reduction hypothesis can explain asynchronous hatching in passerines. Infrared cameras were installed inside nest boxes where great tits (Parus major) were attempting to reproduce in order to determine whether the parents practiced selective feeding of older nestlings. According to the results of the study, no significant difference was observed between the hatching order and the average number of feedings per nestling. In addition, when examining the distribution of food according to hatching order over time, every 30 min, beginning at 9 a.m., selective distribution of food to older nestlings was not observed. In conclusion, use of the brood reduction hypothesis, which supports selective provision of beneficial feeding of older and larger nestlings, to explain the asynchronous hatching of passerines is problematic, thus conduct of future studies focusing on other hypotheses in order to explain the asynchronous hatching of this passerine bird will be necessary.

Insect-associated microorganisms play important roles in the health and development of insects. This study aimed to investigate the similarities and differences in bacterial community structure and composition between the larval gut of Osmia excavata, nest soil, and brood provision from the nest tube. We sequenced larvae gut and their environments’ microorganisms of O. excavata from four locations based on full-length 16S rRNA gene amplicons. The results showed 156, 280, and 366 bacterial OTUs from gut, brood provision, and nest soil, respectively, and three groups shared 131 bacterial OTUs. In the gut, the top two dominant bacteria were Sodalis praecaptivus (68.99%), Lactobacillus micheneri (17.95%). In the brood provision, the top two dominant bacteria were S. praecaptivus (26.66%), Acinetobacter nectaris (13.05%), and in the nest soil, the two most abundant bacteria were Gaiella occulta (4.33%), Vicinamibacter silvestris (3.88%). There were significant differences in diversity between the brood provision groups and the nest soil groups, respectively. Three of the four locations did not differ for gut microbial diversity. Bacteria similar to other solitary bees also existed in the gut of the larvae. Results indicated when the habitat environments were similar, the bacterial community diversity of the gut of O. excavata was similar, despite significant differences among brood provisions and soils, respectively.

This study characterized breeding, housing, feeding and health management practices in positive deviants and typical average performing smallholder dairy farms in Tanzania. The objective was to distinguish management practices that positive deviant farms deploy differently from typical farms to ameliorate local prevalent environmental stresses. In a sample of 794 farms, positive deviants were classified on criteria of consistently outperforming typical farms (p < 0.05) in five production performance indicators: energy balance ≥ 0.35 Mcal NEL/d; disease-incidence density ≤ 12.75 per 100 animal-years at risk; daily milk yield ≥ 6.32 L/cow/day; age at first calving ≤ 1153.28 days; and calving interval ≤ 633.68 days. The study was a two-factor nested research design, with farms nested within the production environment, classified into low- and high-stress. Compared to typical farms, positive deviant farms had larger landholdings, as well as larger herds comprising more high-grade cattle housed in better quality zero-grazing stall units with larger floor spacing per animal. Positive deviants spent more on purchased fodder and water, and sourced professional veterinary services (p < 0.001) more frequently. These results show that management practices distinguishing positive deviants from typical farms were cattle upgrading, provision of larger animal floor spacing and investing more in cattle housing, fodder, watering, and professional veterinary services. These distinguishing practices can be associated with amelioration of feed scarcity, heat load stresses, and disease infections, as well as better animal welfare in positive deviant farms. Nutritional quality of the diet was not analyzed, for which research is recommended to ascertain whether the investments made by positive deviants are in quality of feeds. Full article

Measuring variation in childhood mental health supports the development of local early intervention strategies. The methodological approach used to investigate mental health trends (often determined by the availability of individual level data) can affect decision making. We apply two approaches to identify geographic trends in childhood social, emotional, and behavioural difficulties using the Strengths and Difficulties Questionnaire (SDQ). SDQ forms were analysed for 35,171 children aged 4–6 years old across 180 preschools in Glasgow, UK, between 2010 and 2017 as part of routine monitoring. The number of children in each electoral ward and year with a high SDQ total difficulties score (≥15), indicating a high risk of psychopathology, was modelled using a disease mapping model. The total difficulties score for an individual child nested in their preschool and electoral ward was modelled using a multilevel model. For each approach, linear time trends and unstructured spatial random effects were estimated. The disease mapping model estimated a yearly rise in the relative rate (RR) of high scores of 1.5–5.0%. The multilevel model estimated an RR increase of 0.3–1.2% in average total scores across the years, with higher variation between preschools than between electoral wards. Rising temporal trends may indicate worsening social, emotional, and behavioural difficulties over time, with a faster rate for the proportion with high scores than for the average total scores. Preschool and ward variation, although minimal, highlight potential priority areas for local service provision. Both methodological approaches have utility in estimating and predicting children’s difficulties and local areas requiring greater intervention. Full article

Grey-faced Petrels (Pterodroma gouldi) are colonial burrowing seabirds predominantly nesting on offshore islands of the upper North Island of New Zealand. We studied their chick provisioning on Te Hāwere-a-Maki during two years of unfavourable warmer La Niña conditions in 2011 and 2013. We intensively monitored chicks in each year, weighing chicks every 12 h for 10 consecutive days to estimate meal sizes following chick provisioning and to estimate 12-hourly body mass loss as a function of time since last feeding. We found a quadratic relationship of body mass loss with time since last feeding, with rapid digestion of meals following provisioning followed by a period of fasting from five days post feeding as chicks waited an unknown and variable amount of time until their next meal. The rate of body mass loss did not depend on chick age nor body mass, and did not differ between years, but heavier chicks included in our study were more likely to successfully fledge, suggesting a legacy of adult provisioning prior to our study commencing. Our regular handling of chicks for monitoring has no discernible impact on parent provisioning compared to a set of control chicks. The mean estimates of 100-gram meal sizes and 10-day foraging trip durations are likely to be below the break-even point for this species. Full article

Dam construction for the provision of hydropower and a stable water supply poses a major threat to freshwater biodiversity. Water fluctuation due to dam management has adverse effects on local people and biodiversity in downstream areas, including sandbar-nesting birds. The aim of this research was to determine the effect of water levels controlled by upstream dams on the breeding success of two sandbar-nesting birds, the little ringed plover, Charadrius dubius, and little pratincole, Glareola lacteal, along the Mekong River in Bueng Kan Province, Thailand. During January–May 2018, we found 160 active nests of only two species, the little ringed plover (n = 26 nests, 288 exposure days) and the little pratincole (n = 134 nests, 890 exposure days). Their nest success rates were 19.49 ± 7.52% and 5.54 ± 1.61%, respectively. Predation was a major cause of nest failure for both species (n = 82), followed by flooding (n = 44). We found a significantly increased probability of nest flooding when the water level was higher than when the nest was initiated for those located closer to the water, particularly during March and April, when water levels fluctuated. Our results indicate that dams threaten sandbar-nesting species. Full article
