Music teachers in secondary education tend to undervalue the professional competence of creating music, in response to educational models that prioritise the development of musical interpretation skills. The aim of this research is to identify the factors that contribute to this belief among teachers in Spain, by analysing the results of the Professional Competences of the Music Teacher questionnaire (n = 112). Significant differences were found between age categories, as well as significant linear correlations between teachers’ perceptions of their preparation during initial training, their practical skills and habits, and the professional importance they attached to their competence in musical creation.

Based on the rigorous systematicity assumed in systematic review methodology, it is no surprise that a prominent review such as Macaro et al.'s (2018) on English medium instruction (EMI) has been used as a basis for subsequent EMI research. However, in this article, we explore the ways in which the focus of systematic reviews can be necessarily narrowed and how this poses a risk to research when readers perceive them as offering definitive conclusions on all aspects of a subject. This article addresses two significant trends in applied linguistics. First, systematic review – that is, the use of formalised systems when reviewing literature – has become far more prominent and therefore more impactful than traditional reviews as a methodology (Chong & Plonsky, 2023). Second, there has been an explosive growth in interest in EMI research (Curle et al., 2024). There are further parallels between the two trends, given that both systematic review and EMI are umbrella terms that cover a wide range of research types. As we will see, there is perhaps more disagreement over how to conduct a systematic review than lay readers would suspect. Similarly, EMI is a broader field of research than appears in its most prominent systematic review article. Studies into EMI have explored policy, language learning, the effect on subject knowledge, attitudes towards EMI, ownership of English, and so on. Thus, while EMI is a growingly recognised field of study, it is not always clear what it means to ‘study EMI’.

Health visiting in England is a universal service that aims to promote the healthy development of children aged under five years and safeguard their welfare. We consulted stakeholders about their priorities for research into health visiting and also used these consultations and a literature review to generate a logic model. Parents wanted research to explore how health visiting teams can provide a caring, responsive, accessible service (the mechanisms of change). Policymakers, commissioners, and clinical service leads wanted descriptions and evaluations of currently implemented and ‘gold standard’ health visiting. The challenges to evaluating health visiting (data quality, defining the intervention, measuring appropriate outcomes, and estimating causal effects) mean that quasi-experimental studies that rely on administrative data will likely underestimate impact or even fail to detect impact where it exists. Prospective and experimental studies are needed to understand how health visiting influences infant–parent attachments, breastfeeding, childhood accidents, family nutrition, school readiness, and mental health and well-being.

Giving money to candidates is an important but unequal form of political voice. Among those Americans worst represented as campaign contributors are Black women and Latinas. Although inequalities in income and wealth fuel inequalities in campaign contributions, resources are an incomplete explanation. This study investigates, for Black women and Latinas, whether their views on donations to candidates differ from their views on other forms of civic and political engagement. The results, including the absence of a shared norm about giving to candidates, illuminate the challenges and opportunities of mobilizing a more representative group of campaign contributors.

The box-ball systems are integrable cellular automata whose long-time behavior is characterized by soliton solutions, with rich connections to other integrable systems such as the Korteweg-de Vries equation. In this paper, we consider a multicolor box-ball system with two types of random initial configurations and obtain sharp scaling limits of the soliton lengths as the system size tends to infinity. We obtain a sharp scaling limit of soliton lengths that turns out to be more delicate than that in the single color case established in [LLP20]. A large part of our analysis is devoted to studying the associated carrier process, which is a multidimensional Markov chain on the orthant, whose excursions and running maxima are closely related to soliton lengths. We establish the sharp scaling of its ruin probabilities, Skorokhod decomposition, strong law of large numbers and weak diffusive scaling limit to a semimartingale reflecting Brownian motion with explicit parameters. We also establish and utilize complementary descriptions of the soliton lengths and numbers in terms of modified Greene-Kleitman invariants for the box-ball systems and associated circular exclusion processes.

The Russian invasion of Ukraine in February 2022 has had profound effects on the stability and security of Europe. This study examines the attitudes of Europeans toward the European Union (EU) in the aftermath of the invasion of Ukraine. Using Special Eurobarometer data collected between February and April 2022 with a representative sample of the EU (N = 26,502), it leverages the quasi-experimental setting with the coincidence between the timing of the invasion and the fieldwork period of the Eurobarometer. Our findings indicate a general increase in support for the EU in the aftermath of the invasion by 4 percentage-points (11 percent of a SD). While the amplitude of the effect remains similar, we see larger treatment effects as more days passed after the invasion. We also observe significant variation at the individual level in treatment effects, particularly by ideology, with left-leaning individuals being more critical of the EU following the invasion. In general, our research demonstrates the significant impact of regional conflicts on public attitudes toward supranational organizations such as the EU and highlights the role of the EU as a provider of security and stability in the face of such conflicts.

Callous-unemotional (CU) traits represent a risk factor for persistent, severe levels of externalizing problems. Irritability may predict the development of CU traits for some individuals, who are thought to acquire them in reaction to negative environmental experiences. Models on the development of CU traits have emphasized the socializing role of harsh parenting to the neglect of negative peer experiences. The present study 1) tested primary and alternative models of physical and relational peer victimization as socialization agents in relations between irritability and CU traits; and 2) considered hypothalamic-pituitary-adrenal-axis functioning as a moderator of these associations. Gender moderation was also considered. Aims were tested from middle childhood to adolescence using data from the NICHD Study of Early Child Care and Youth Development, which includes a large national sample (N = 1,077) and multiple methods and informants for the constructs of interest. Positive associations between irritability, peer victimization, and CU traits were supported, with indirect effects on CU traits supported specifically from peer victimization through increases in irritability. Associations between relational victimization, irritability, and CU traits may be particularly salient for females, whose experiences have been neglected to date. However, effects were small, and replication efforts are needed.

In Europe, the integration process has domesticated international relations, safeguarded member-states’ democracies, and enabled collective action and supranational problem-solving. It has brought about the European Union (EU) and a democratic ‘surplus’. How has this been possible when the binding effect of EU law is grounded neither in the sovereign’s monopoly on power at the European level nor in the final decision-making authority of the EU? An answer to this puzzle is found in the fact that a public coercive framework has been established, which aims at solving the indeterminacy and assurance problems facing international cooperation. The enabling condition of sovereignty is replaced by those of co-legislation and a binding judicial process. The latter creates reasons for deference to legitimate authority and hence a compliance condition. However, since the Union falls short of meeting certain democratic standards, oversteps competences, and is plagued with inertia, there is a call for constitutional reform.

The Eichler–Selberg trace formula expresses the trace of Hecke operators on spaces of cusp forms as weighted sums of Hurwitz–Kronecker class numbers. We extend this formula to a natural class of relations for traces of singular moduli, where one views class numbers as traces of the constant function $j_0(\tau )=1$. More generally, we consider the singular moduli for the Hecke system of modular functions

For each $\nu \geq 0$ and $m\geq 1$, we obtain an Eichler–Selberg relation. For $\nu =0$ and $m\in \{1, 2\},$ these relations are Kaneko’s celebrated singular moduli formulas for the coefficients of $j(\tau ).$ For each $\nu \geq 1$ and $m\geq 1,$ we obtain a new Eichler–Selberg trace formula for the Hecke action on the space of weight $2 \nu +2$ cusp forms, where the traces of $j_m(\tau )$ singular moduli replace Hurwitz–Kronecker class numbers. These formulas involve a new term that is assembled from values of symmetrized shifted convolution L-functions.

This article contributes to the growing research field investigating intensive intervention programmes aimed at families with complex needs, focusing on the experiences of long-term poor families in Norway. There is a growing public concern about social inequalities in Norway, especially regarding child poverty and the negative effects of social and economic exclusion. The innovation project New Patterns is a means to compensate for the present silo-organised social welfare system, opting to develop holistic services targeting poor families with diverse challenges. Based on interviews and observation, the article examines how parents experience being subjected to extensive but voluntary family intervention by a designated family coordinator. We analyse what forms of change they are identifying as happening after working with the family coordinator. We find that the changes they identify can be labelled both as small moments and turning points and argue that small moments can instigate decisive changes.

Preserved records of tooth–bone interactions, known as tooth marks, can yield a wealth of information regarding organismal behavior and ecology. For this reason, workers in a wide range of disciplines, but particularly paleontology, have inspected and interpreted these features for decades. Although previous studies have gleaned invaluable insights, they have also described tooth marks using terminological frameworks that have been incompletely defined, have incorporated behavioral hypotheses in definitions, and/or have been inconsistently applied. To address these problems, we introduce the category-modifier (CM) system, the first system to both sort tooth marks into clearly defined main categories and use descriptive modifiers to characterize their appearance more precisely. The CM system is designed to apply to a wide range of vertebrates, to enable comparisons across disciplines and studies, and to help researchers keep their investigations into behavioral hypotheses free of circular reasoning.

We establish a McKay correspondence for finite and linearly reductive subgroup schemes of ${\mathbf {SL}}_2$ in positive characteristic. As an application, we obtain a McKay correspondence for all rational double point singularities in characteristic $p\geq 7$. We discuss linearly reductive quotient singularities and canonical lifts over the ring of Witt vectors. In dimension 2, we establish simultaneous resolutions of singularities of these canonical lifts via G-Hilbert schemes. In the appendix, we discuss several approaches towards the notion of conjugacy classes for finite group schemes: This is an ingredient in McKay correspondences, but also of independent interest.

Developing countries, with limited monitoring and auditing capabilities, face significant tax evasion issues. This study examines the impact of various text message combinations on promoting tax compliance, particularly in encouraging service providers to submit monthly sales tax returns in Khyber Pakhtunkhwa, Pakistan. A randomised controlled trial involved 18,087 service providers and tested three types of SMS reminders. These included a basic reminder for the due date, a reciprocity message emphasising social responsibility, and a loss aversion (LA) message highlighting financial penalties and deactivation. Subsequently, service providers who didn’t file on time received one of three warning messages. These warnings included a basic alert about potential legal action, financial penalties, and deactivation, as well as a message framing continued non-compliance as an active choice (AC). Overall, the interventions did not significantly influence tax filing behaviour beyond basic reminders and warnings. However, compliance improved for early registrants with the LA reminder and AC warning, and these results were robust to multiple hypothesis testing corrections. Compliance worsened for recent registrants in all combinations except the LA reminder and AC warning. These findings suggest that targeted low-cost messages that convey vague threats can improve tax compliance among certain taxpayer groups.

In response to the crisis in validity of the Diagnostic and Statistical Manual of Mental Disorders, psychiatry has seen a proliferation of alternative research frameworks for studying and classifying psychiatric disorders. In this paper, I argue that the existence of multiple frameworks in which each employs their own standards of validity is problematic methodologically speaking for trying to do any kind of unified validation work. Fundamental disagreements concerning the underlying phenomenon, sources of validating evidence, and the very nature of validity move each framework into an unrecognized plurality. The consequence for psychiatry is a new validity crisis.

Commonly occurring mental health disorders have been well studied in terms of epidemiology, presentation, risk factors and management. However, rare or uncommon mental health disorders and events are harder to study. One way to do this is active surveillance. This article summarises how the Royal College of Psychiatrists Child and Adolescent Psychiatry Surveillance System was developed, as well as the key studies that have used the system and their impact, to make the case for a wider international surveillance unit for child and adolescent psychiatry. Keeping this surveillance active in different populations across the globe will add to existing knowledge and understanding of these uncommon disorders and events. This will in turn help in developing better frameworks for the identification and management for these disorders and events. It will also facilitate the sharing of ideas regarding current methodology, ethics, the most appropriate means of evaluating units and their potential applications.

Seeds of many Amazonian floodplain forest trees are dispersed during high-water periods and spend weeks or months underwater until the flooding retreats. To assess whether prolonged seed submersion affects germination and early seedling development, an experiment was carried out in a greenhouse with seeds of Campsiandra laurifolia, Cassia leiandra, Crataeva tapia, Ilex inundata, Macrolobium acaciifolium, Nectandra amazonum, Pouteria glomerata, Psidium acutangulum, Sorocea duckei, and Vitex cymosa. They are common in this type of forest, differ in fruit type, number of seeds per fruit, fruit dimensions, and fresh mass and have fruits or seeds that can float. Seeds were collected in a Central Amazonian floodplain forest (flooded approximately 6 months year−1; water column of 5 m) and germinated in (1) irrigated soil or (2) underwater (water column of 5–7 cm) for 6 months. Seeds that germinated underwater were transferred to drained soil. Seeds of all species germinated underwater and developed seedlings when transferred to soil. However, submersion reduced the germination percentage of Psidium acutangulum, N. amazonum, P. glomerata and V. cymosa. Six species delayed germination in water. Ca. leiandra, I. inundata and P. glomerata did not differ in mean germination time in drained soil and underwater, whereas S. duckei seeds germinated faster underwater. Seed submersion negatively affected seedling growth (shoot length) of three species but did not affect seedling biomass. Timing of fruit dispersal, fruit buoyancy and high number of seeds per fruit can be critical for species with seeds that are not as able to cope with long-term submersion.

Geometric morphometrics facilitates the quantification and visualization of variation in shape and proportion through the comparison of homologous features. Eublastoidea, a Paleozoic echinoderm clade with a conservative body plan, is an ideal group for morphometric analysis, because their plate junctions are homologous and identifiable on all species. Eublastoids have previously been grouped taxonomically by generalized shape types (e.g., globose). These shapes are often used in taxonomic descriptions and as characters in phylogenetic analyses. The underlying homology of these broad shape types has never been explored. Herein we apply the first comprehensive use of three-dimensional geometric morphometrics (3D GMM) on fossil echinoderms to investigate taxonomic assignments, temporal distribution, and whether the varying proportions of skeletal elements that produce the gross thecal morphology are distinguishable. Taxonomic assignments specifically at the ordinal and family levels show varying amounts of overlap in morphospace, suggesting that many assignments may not be reevaluated. Our results suggest that none of the generalized shape types are distinct in morphospace and, therefore, likely do not capture the homologous changes in taxa. The plate circlet ratios showed trends specifically relating to the deltoid plate circlet, which has the most variability. We reanalyzed previous work and subsetted our data to be more comparable and found that there are key differences between methodologies and landmarks that will require future evaluation. Applying modern technological methods to previously explored questions allows for an updated understanding of this important fossil clade and provides a framework for others to assess fossil clades in a similar manner.

This essay reviews the contribution of Stuart Elden to the scholarship relating to the French philosopher Michel Foucault. In particular, the essay considers Elden’s impressive four-volume intellectual history of Foucault’s career: The Early Foucault (2021), The Archaeology of Foucault (2023), The Birth of Power (2017), and Foucault’s Last Decade (2016). While acknowledging the thoroughness of Elden’s research, the essay analyzes Elden’s reluctance to offer a comprehensive interpretation of Foucault’s thought and his failure to say anything about his significance as a thinker. The essay concludes by considering Elden’s work as a symptom of “Foucault scholasticism.”
