The earliest pottery vessels in the Arabian Gulf, appearing in the mid-sixth millennium BC, belong to two distinct traditions: Ubaid Ware was imported from Mesopotamia, but the origins of the Coarse Red Ware have remained obscure. Geochemical examination of pottery from Bahra 1, in modern-day Kuwait, and geological samples from the surrounding area reveal a regional origin for the clay. Further exploration of the Bahra 1 assemblage indicates that Coarse Red Ware was probably made at the site by low-skilled potters. This research provides insights into the organisation of pottery production and distribution in the Arabian Neolithic.

Let ${\mathcal {A}}$ be a unital ${\mathbb {F}}$-algebra and let ${\mathcal {S}}$ be a generating set of ${\mathcal {A}}$. The length of ${\mathcal {S}}$ is the smallest number k such that ${\mathcal {A}}$ equals the ${\mathbb {F}}$-linear span of all products of length at most k of elements from ${\mathcal {S}}$. The length of ${\mathcal {A}}$, denoted by $l({\mathcal {A}})$, is defined to be the maximal length of its generating sets. We show that $l({\mathcal {A}})$ does not exceed the maximum of $\dim {\mathcal {A}} / 2$ and $m({\mathcal {A}})-1$, where $m({\mathcal {A}})$ is the largest degree of the minimal polynomial among all elements of the algebra ${\mathcal {A}}$. As an application, we show that for arbitrary odd n, the length of the group algebra of the dihedral group of order $2n$ equals n.

The authors offer reflections and lessons learned in a single pediatric tertiary center’s experience during a pediatric mass casualty incident (MCI). The MCI occurred at a holiday parade and the patients were brought to multiple community emergency departments for initial resuscitation prior to transfer to the Pediatric level 1 trauma center. In total, 18 children presented with severe blunt force trauma after a motor vehicle entered the parade route. Following initial triage in emergency departments, 10 of 18 children injured during the incident were admitted to the Pediatric Intensive Care Unit, collectively representing a system-wide stressor of emergency medicine, critical care, and surgical services. Institutional characteristics, activation of personnel and supplies, and psychosocial support for families during an MCI are important to consider in children’s hospitals’ disaster preparedness planning.

There is a pressing need for novel approaches to help address climate change and for a workforce that is equipped with a combination of new and different types of knowledges. The One Health (OH) core competencies perhaps offer the new knowledges, skills, and attitudes that will be needed in a future generation of practitioners that does not shy away from complexity. The objective of this research was to identify overlapping and transferable OH-climate change competencies that are needed of professionals working to address climate change. Using focus groups and qualitative content analysis, 23 professionals from across Canada whose employment positions had a key focus on climate change were brought together across five sessions. Participants agreed that the OH competencies were applicable to their employment roles and responsibilities, but they identified four key missing areas that are important for graduates: evaluative and reflective practice, personal resilience, turning knowledge into action, and having an openness to other knowledges (particularly Indigenous and non-Western viewpoints). This work also provided a first iteration of a process that should be continually used to bridge the gap between theory and practice, as employer needs are a key consideration during the development of educational programs.

In this article, we extend, with a great deal of generality, many results regarding the Hausdorff dimension of certain dynamical Diophantine coverings and shrinking target sets associated with a conformal iterated function system (IFS) previously established under the so-called open set condition. The novelty of the result we present is that it holds regardless of any separation assumption on the underlying IFS and thus extends to a large class of IFSs the previous results obtained by Beresnevitch and Velani [A mass transference principle and the Duffin–Schaeffer conjecture for Hausdorff measures. Ann. of Math. (2) 164(3) (2006), 971–992] and by Barral and Seuret [The multifractal nature of heterogeneous sums of Dirac masses. Math. Proc. Cambridge Philos. Soc. 144(3) (2008), 707–727]. Moreover, it will be established that if S is conformal and satisfies mild separation assumptions (which are, for instance, satisfied for any self-similar IFS on $\mathbb {R}$ with algebraic parameters, no exact overlaps and similarity dimension smaller than $1$), then the classical result of Hill–Velani regarding the shrinking target problem associated with a conformal IFS satisfying the open set condition (and for which the Hausdorff measure was later computed by Allen and Barany [On the Hausdorff measure of shrinking target sets on self-conformal sets. Mathematika 67 (2021), 807–839]) can be extended.

This article uses a new database of 1,891 probate inventories from rural southern Sweden to investigate the development of rural households’ productive capacity from the late 1600s to the 1860s. Both labourers and farmers improved their material living standards – as measured by the contents of probate inventories – but the labouring households’ ownership of means of production decreased over time. This indicates increasing market involvement and dependency on wage labour. For labourers’ and farmers’ households alike, textile production at home became more important; in the 1860s, half of the labouring households owned spinning wheels and weaving looms, and for farmer households, the shares were even higher. Our study reveals not only the dynamism of the rural pre-industrial Swedish economy but also the unequal nature of this dynamism.

Numerous developmental findings suggest that infants and toddlers engage predictive processing during language comprehension. However, a significant limitation of this research is that associative (bottom-up) and predictive (top-down) explanations are not readily differentiated. Following adult studies that varied predictiveness relative to semantic-relatedness to differentiate associative vs. predictive processes, the present study used eye-tracking to begin to disentangle the contributions of bottom-up and top-down mechanisms to infants’ real-time language processing. Replicating prior results, infants (14-19 months old) use successive semantically-related words across sentences (e.g., eat, yum, mouth) to predict upcoming nouns (e.g., cookie). However, we also provide evidence that using successive semantically-related words to predict is distinct from the bottom-up activation of the word itself. In a second experiment, we investigate the potential effects of repetition on the findings. This work is the first to reveal that infant language comprehension is affected by both associative and predictive processes.

Within bioethics, two issues dominate the discourse on suffering: its nature (who can suffer and how) and whether suffering is ever grounds for providing, withholding, or discontinuing interventions. The discussion has focused on the subjective experience of suffering in acute settings or persistent suffering that is the result of terminal, chronic illness. The bioethics literature on suffering, then, is silent about a crucial piece of the moral picture: agents’ intersubjectivity. This paper argues that an account of the intersubjective effects of suffering on caregivers could enrich theories of suffering in two ways: first, by clarifying the scope of suffering beyond the individual at the epicenter, i.e., by providing a fuller account of the effects of suffering (good or bad). Second, by drawing attention to how and why, in clinical contexts, the intersubjective dimensions of suffering are sometimes as important, if not more important, than whether an individual is suffering or not.

Wood apple (Limonia acidissima L., Rutaceae) is a medium to large-sized semideciduous tree native to Indian subcontinent. The Indian systems of medicine recognized this tree for its medicinal properties and nutritional fruit. The present study evaluates chemotypic diversity by using HPTLC method for identification of elite genotypes among 96 accessions of wood apple leaves collected from diverse populations across 16 states of India. Here, the multivariate analysis, including the extent of variation, broad sense heritability, genetic advance, correlation of mean value of each replicate were assessed with respect to four target bioactive molecules (quercetin, stigmasterol, psoralen and niloticin) extracted from leaves of wood apple. The results showed that the analysis of variance revealed significant variabilities for all the four biomolecules analysed. The hierarchical clustering grouped all the accessions into eight clusters. Out of which, cluster II and VI contained a maximum of 20 and 18 genotypes, respectively. Cluster VIII consisted of only three genotypes. The intra-cluster distance ranged from 0 (cluster II to VIII) to 6.83 (cluster I). The highest inter-cluster distance was found between clusters V and VII (22.52). Positive correlation was found between chemotypic traits at both the genotypic and phenotypic level. The broad sense heritability was recorded highest for quercetin (97.7%). The high genetic advance was noticed for niloticin (217.4). This study detected significant chemotypic variation among the accessions. The elite accessions identified in this study could be utilized to enhance the quality, efficacy and economic value of medicinal products.

Young people with childhood adversity (CA) were at increased risk to experience mental health problems during the COVID-19 pandemic. Pre-pandemic research identified high-quality friendship support as a protective factor that can buffer against the emergence of mental health problems in young people with CA. This longitudinal study investigated friendship buffering effects on mental health symptoms before and at three timepoints during the pandemic in 102 young people (aged 16–26) with low to moderate CA. Multilevel analyses revealed a continuous increase in depression symptoms following the outbreak. Friendship quality was perceived as elevated during lockdowns and returned to pre-pandemic baseline levels during reopening. A stress-sensitizing effect of CA on social functioning was evident, as social thinning occurred following the outbreak. Bivariate latent change score modeling revealed that before and during the pandemic, young people with greater friendship quality self-reported lower depression symptoms and vice versa. Furthermore, sequential mediation analysis showed that high-quality friendships before the pandemic buffered depression symptoms during the pandemic through reducing perceived stress. These findings highlight the importance of fostering stable and supportive friendships in young people with CA and suggest that through reducing stress perceptions high-quality friendships can mitigate mental health problems during times of multidimensional stress.

In this article, we examine the extent to which Christians and Muslims endorse divine foreknowledge for neutral, good, and bad actions. If they do, the problem of theological fatalism is not a mere (albeit important) philosophical difficulty, but a problem rooted in lay believers’ intuitive understanding of God.

Court records are rich primary sources to social historians, and much attention has been paid to these types of documents in different African territories. In most cases only summaries have survived, but in Angola complete proceedings have been preserved. Examining the court case collection available at the Benguela District Court, we discuss its strengths and methodological challenges, and present possible themes for future research. The use of these records reveals new aspects of the Angolan past, including more information on local norms and the ability of African women to use the Portuguese courts.

Education is essential for addressing the global environmental crisis and engaging students through experiential learning is crucial. In physical education, physical literacy offers a holistic approach to sustainable education, with plogging exemplifying this integration. This study investigates the perceptions of Physical Education Teacher Education (PETE) students regarding the implementation of plogging in school curricula. Using qualitative interviews with 80 PETE students and analysing responses with NVIVO 12 software, the study reveals mixed feelings about this innovative practice. Participants see plogging as valuable for fostering both physical literacy and environmental awareness. However, concerns about feasibility include the need for institutional support, curriculum flexibility and community involvement. These findings highlight the potential of plogging to enhance educational programmes by combining physical activity with environmental stewardship. The results can inform the development of future educational strategies that integrate plogging to promote sustainability and holistic student development.

Members of the genus Actinia are familiar members of rocky shore communities across much of the world. However, to date, no Actinia species have been reported from the North American continent. Here, we report Actinia from an approximately 22 km length of the New Jersey, US shoreline, where it was first discovered in 2021. Morphology and DNA barcoding data (mitochondrial cytochrome c oxidase I and nuclear internal transcribed spacer) indicate that these populations are Actinia equina. The presence of these populations close to major ports in New Jersey, New York, and Philadelphia suggests a probable introduction from shipping activities.

The International Court of Justice (ICJ), often referred to as the “World Court,” plays a central role in the field of international law. Despite the significance of this court, socio-legal scholarship has not examined the ICJ’s inner workings due to limited access. Drawing from field theory and organizational theory, this study addresses this gap by using various data sources including interviews, organizational documents, and publicly available texts from insiders. Based on this data, this article explores how the ICJ’s institutional context shapes its organization and the experiences of its actors. We argue that the ICJ provides a space that tightly connects institutional myths, organizational practices, and individual action. This tight coupling effectively mediates and manages differences among ICJ actors, fostering a stable practice of international law within a field otherwise marked by conflict. This enables the ICJ to produce and sustain a specific way of doing international law which has stabilizing effects in this field. By linking the macro level of the field – an area emphasized in prior scholarship – with a microlevel organizational perspective, this article offers a nuanced understanding of the conflicts and organizational practices influencing the ICJ’s operations and development of international law.

The present study aimed to utilize maize landraces from the North Eastern Hill Region (NEHR) of India for hybrid development, addressing the absence of established heterotic groups for maize in this region. Eighty inbreds derived from diverse local landraces were test-crossed to two testers LM-13 and LM-14. The 160 testcrosses were evaluated over two seasons using an alpha lattice design. Heterotic grouping studies utilizing BLUP values, included analyses of specific combining ability (SCA), specific and general combining ability (HSGCA), and GCA of multiple traits (HGCAMT). Additionally, 34 SSR markers were employed to group the inbreds based on genetic distance (SSR_GD). Breeding efficiency tests indicated that the conventional SCA and HSGCA methods were the most effective for heterotic grouping, enabling classification of the overlapping inbreds into the corresponding tester groups. Validation involving 10 inbreds – 5 from each tester group crossed in a full diallel fashion – revealed that gene action was predominantly non-additive, a prerequisite for heterosis breeding. The highest-performing hybrids exhibited better parent heterosis (BPH) ranging from 75 to 384%, demonstrating significant yield advantages. These hybrids combined moderately divergent parents with contrasting female and male GCA values and BPH was significantly associated with SCA effects, providing predictive insights for optimizing hybrid development. The findings of this study highlight the potential of NEHR germplasm for developing high-yielding hybrids tailored to local conditions. These hybrids would particularly benefit smallholding farmers practicing shifting cultivation by enabling cost-effective production and providing economic benefits.
