In this article, we present an innovative programming and instructional practice to foster the social-emotional competence of twice-exceptional students — those who are gifted and have a learning disability. We review the benefits of bibliotherapy, provide an overview of the structure of a developmental bibliotherapy intervention, and identify potential barriers to implementation before providing a guide for teachers. Gifted students with attention-deficit/hyperactivity disorder (ADHD) may be supported to develop social-emotional wellbeing and competence through developmental bibliotherapy. Due to a gap in the research with this particular population of students, we focused on reviewing research that explored the use of bibliotherapy with gifted students specifically and the wider student population generally. This instructional practice can be utilised by counsellors, teachers, and gifted and talented coordinators to meet the unique needs of this student population in Australian primary schools. A reflection on the implementation of this guide for gifted students is shared from a practitioner’s perspective to conclude the article.
This paper explores the multiple stories and affective traces that wetlands and swamps generate in more-than-human environments. Situated on what was once a swamp, Naarm (Melbourne) provides the setting for the authors’ collective creative inquiry. This work explores more-than-human methodologies of knowledge creation, examines how these approaches impact multispecies justice and investigates how wetlands can serve as transitional, unstaged spaces that challenge and disrupt colonial infrastructures. While drawing back on memories and experiences of wetlands in Southern China and Southeast Europe, the authors incorporate poetic mappings and autoethnographic interviews in exploring the reminisces and encounters living with more-than-human pasts and presents. Following the way of wetlands, the authors seek to foster unexpected ecologies between water, land, species and a multiplicity of ontologies in the abundance of in-between spaces as a generative learning-creation site.
We present computations of individual mode-to-mode energy transfers from direct numerical simulations of homogeneous isotropic turbulence. Unlike previous approaches based on shell-filtered velocity fields, this method distinguishes between the energy exchanged by each pair of modes within a triad. We introduce a potential function based on the energy content of the modes involved, and show that it predicts the distribution of intense energy transfers in the vicinity of the sampling mode considered. By performing simulations with forcing applied at intermediate wavenumbers, we demonstrate that the region of most intense transfers is determined by the spectral location of the energy-containing scales rather than by the local or non-local character of the triad. Direct energy exchanges with the energy-containing range are suppressed by geometric constraints from the divergence-free condition, but persist as residuals when the sampling mode is close to the energy-containing scales. The comparison with an estimator derived from eddy-damped quasi-normal Markovian theory shows good agreement and recovers the forward, scale-local nature of energy transfer consistent with the cascade picture.
Drug use disorder (DUD) clusters in families due partly to shared environment, including sibling influences. Low academic achievement (AA) in adolescence increases DUD risk. This study examined whether low AA in an older sibling causally increases DUD risk in younger siblings.
Methods
We studied all Swedish full sibling pairs (n = 309,666) born 1972–1985 and ≤ 5 years apart. Older sibling AA was assessed at age 16. Using Month-of-Birth (MoB) as an instrument, we conducted instrumental variable (IV) analyses and propensity score (PS) models to evaluate the causal impact of older sibling AA on younger sibling DUD risk, assessed by DUD registration in national medical, criminal, or pharmacy registries.
Results
Older sibling AA significantly predicted younger sibling DUD risk across models. Beta coefficients (±95% CI) were 2.04 (1.97–2.12) in raw analysis, 1.88 (0.74–3.02) in IV, and 1.26 (1.17–1.34) in PS models. Together with the strong first-stage association, the IV estimates remain positive under small departures from the ideal identifying assumptions. Effect sizes declined with increasing sibling age differences (p = 0.036 for IV; p < 0.0001 for PS) and were strongest in male–male pairs (IV: 4.01 [1.42–6.61]; PS: 1.74 [1.55–1.93]). Mediation by older sibling DUD was modest.
Conclusions
Findings from two causal inference approaches support a largely causal link between low AA in an older sibling and increased DUD risk in younger siblings. Stronger effects in close-aged and male–male pairs further support this conclusion. Interventions to improve AA in older siblings may yield indirect preventive benefits for younger siblings.
The ‘Digital Economy and Society Index’ (DESI) Dashboard for the Digital Decade is a set of indicators created by the European Union in the early 2010s to monitor Member States’ progress in pursuing the EU’s Digital Agenda, as well as many of the goals of the UN’s 2030 Agenda for Sustainability. The figures provided by the Dashboard are perceived by academics, the media and the general public as objective neutral data on the progress of Member States towards digitalisation, and on the promotion of sustainable development. This short contribution unpacks the Dashboard, examining the variables it considers and the methodology it employs, and finds out a very different picture. The Dashboard mainly assesses how easily people can access products and services online. It thus promotes a pro-market digitalisation agenda that excludes any other possible alternative and has little to do (if any) with the idea of sustainability. As is often the case with quantitative measurements of social phenomena, behind its seemingly scientific numerical veil the Dashboard conveys a policy vision that is hardly compatible with the objectives the Dashboard allegedly promotes. The essay thus raises broader questions as to the legitimacy of governing through indicators and as to the role of EU in shaping Member States’ digital future.
This paper examines the performance of smallholder crop farmers across different land ownership categories in Ghana. Using a metafrontier model, the study estimates technical efficiencies and productivity levels among farmers with formal land deeds, those without deeds, and non-landowners. The results show that land, labor, and capital significantly impact crop production across ownership categories, while social capital, income, and demographics influence managerial performance. Farmers with formal land deeds and those cultivating family-owned land exhibited superior production technologies. Enhancing access to extension services, credit, and farmer-based organizations, alongside collaboration with traditional chiefs and family heads, can improve land tenure security and productivity.
In this essay, “Writing Gone Wao,” I begin by reiterating my own sense of the book’s (Junot Díaz: On the Half-Life of Love, Duke UP, 2022) priorities. I then turn to the probing and generous responses by Glenda Carpio, Mónica González García, Gerald Torres, Marina De Chiara, and Ato Quayson to my work. I conclude by examining Díaz’s recent writings published after my book appeared, including his complex, erudite Substack series “StoryWorlds with Junot Díaz,” and his short story, “The Ghosts of Gloria Lara” (The New Yorker, 2023), where he explores dramatic issues of decolonial love and the political unconscious.
Let $N \ge 1$, $k \ge 2$ even, and $\sigma$ denote a sign pattern for N. In this paper, we first determine the exact proportion of forms in $S_k(N)$ and $S_k^{\mathrm{new}}(N)$ with a given Atkin–Lehner sign pattern $\sigma$. Then we study the asymptotic behaviour of the Hecke operators $T_p$ over the subspaces of $S_k(N)$ and $S_k^{{\mathrm{new}}}(N)$ with Atkin–Lehner sign pattern $\sigma$. In particular, for the p-adic Plancherel measure $\mu_p$, we show that the Hecke eigenvalues for $T_p$ over these subspaces are $\mu_p$-equidistributed as $N+k \to \infty$.
Comparing the coverage by The New York Times and two Black newspapers of four episodes of protests about police violence in New York in the late 1990s reveals key differences in the implicit political agendas of the two sources. The New York Times implicitly reinforced dominant political institutions and focused on short-term issues. It emphasized partisan politics as protest motivations, quoted police extensively and often printed material sympathetic to police, and typically portrayed protesters as angry or motivated by politics. Black newspapers emphasized collective resistance to long-term systemic problems with police, moral condemnation of police violence, the connection of current protests with past oppression and struggles, the involvement of youth, and Black immigrants’ growing awareness of anti-Blackness. The findings of this study explain how racialized collective memories and collective identities are formed, sustained, and/or erased in interaction with institutional politics in media discourse.
This paper presents a novel self-octuplexing substrate-integrated waveguide (SIW) cavity-backed slot antenna for eight-band wireless communication services. This antenna employs eight semi-elliptical-shaped slots on an octagonal SIW cavity with different lengths to radiate at eight different frequencies. The eight radiating frequencies are 2.7, 3, 3.3, 3.6, 3.9, 4.2, 4.5, and 4.72 GHz, with impedance matching is less than −10 dB. Each radiator is backed by an eighth-mode SIW cavity and excited by a 50 Ω microstrip line. A designed prototype of the antenna is fabricated and tested. It has more than 34 dB measured isolation among any two ports. The maximum measured antenna gains are 4.4, 4.19, 4.11, 4.03, 4.19, 4.28, 5.2, and 5.44 dBi at the respective operating frequencies. It has a measured cross-polarization level of below −24.2 dB in the boresight direction and a front-to-back ratio of more than 10.4 dB in all the bands. All the slots can be tuned independently to radiate at the desired frequency band. This antenna can easily be integrated with other planar circuits due to an unperturbed ground plane.
If change is the only constant, how does the law keep pace with technology? Without a centralized judiciary, international law should be especially susceptible to disruption, yet it can be remarkably resilient in practice. I argue that efforts to minimize legal ambiguity, long seen as integral to compliance, can hinder its application to new technologies. Drawing on first principles from psycholinguistics, my theory differentiates between what I call convergent and divergent forms of flexibility. Unlike divergent flexibility, which gives rise to contestation, convergent flexibility tends to promote consensus, even when (1) technology is unprecedented and (2) regulatory interests sharply diverge. To test the theory, $450$ trained legal professionals were commissioned to take part in a randomized controlled trial (RCT) that varied technological novelty, legal precision, and political incentives. Participants collectively contributed 280,000 words over 10,000 hours in defense of their professional legal opinions, offering a novel (agent-subjective) measure of compliance. To establish external validity, the experiment is complemented with research into the legal impact of two breakthrough chemical weapons technologies: “super tear gas” and novichok. The findings contribute a general theoretical framework for understanding when and why emerging technologies are legally disruptive.
Piperacillin–tazobactam is a beta-lactam antibiotic with a distinct R1 side chain compared to other penicillins, therefore the risk of cross-reactivity should be theoretically low. Despite this difference, antimicrobial guidelines recommend against using piperacillin–tazobactam in patients with penicillin allergies. There is limited data available regarding piperacillin–tazobactam use in patients with a penicillin allergy, or rates of cross-reactivity. Therefore, the objective of this study was to assess the incidence of cross-reactivity to piperacillin–tazobactam in patients with a labeled penicillin allergy.
Methods:
This was a retrospective study of patients admitted to Surrey Memorial Hospital (SMH) between November 1st, 2021 to January 31st, 2024 assessing tolerance to piperacillin–tazobactam in patients with prior labeled penicillin allergies. Baseline characteristics and outcomes were collected from electronic medical records (EMR).
Results:
Of the 191 patients included, 98% were found to tolerate one or more doses of piperacillin–tazobactam. This included 95 patients with “low risk delayed reactions,” 90 patients with “high risk anaphylactic reactions,” and 2 patients with “well-documented delayed reactions,” to penicillins. Only four patients out of 191 had documented intolerance to piperacillin-tazobactam post-exposure.
Conclusion:
This study suggests that piperacillin–tazobactam has a low risk of intolerability (2%) in patients with labeled penicillin allergies, and that it is reasonable to consider piperacillin–tazobactam as an alternative to carbapenems and other broad-spectrum antibiotics for most patients with a previous penicillin allergy.
This article examines the most renowned electroacoustic music festival in Chile so far, from its first edition in 2001 to 2012, when its continuity was interrupted. It focuses on two aspects that appeared relevant and took place consistently during the period under study: (1) the generation of networks, circulations and aesthetic crossovers that were favoured by the festival; and (2) the perspective of the electroacoustic concert as a space for research and experimentation in devices and formats deemed appropriate for a particular experience of music. To this end, primary and archival sources of the article’s author as well as other direct participants in the festival’s organisation were reviewed. Based on this, the relevance of these types of activities in the dissemination of these art forms is determined, as well as the need for proper management to grow and consolidate these spaces.
This article investigates the recent development of formal childcare services in China, focusing on the policy framework introduced since 2019 and its implementation in three county-level regions. Drawing on Mahon’s typology of childcare welfare models, it identifies China’s approach as a tailored third way model, characterised by reliance on private investment, limited public funding, and the assignment of primary caregiving responsibilities to families. Based on policy analysis and qualitative fieldwork, the study reveals significant gaps between policy goals and service accessibility. While formal childcare is framed as a solution to declining fertility and work-life imbalance, high service costs and inadequate local support have constrained equitable access. The Chinese case suggests that without stronger public investment and gender-equality measures, the third way model is unlikely to sustain women’s employment and may deepen social inequalities.
This study aimed to evaluate the effects of linseed supplementation on the in vitro production of embryos subjected to vitrification. Pantaneira cows supplemented with linseed or not (control) were evaluated. The best-quality embryos produced in vitro from both groups were vitrified. Oocyte quality and blastocyst rate did not differ between the groups. However, the rates of vitrifiable embryos and re-expansion at 3 h were higher in the linseed-supplemented group. In conclusion, linseed supplementation in Pantaneira cows improved the quality of embryos produced in vitro.
The Kyoto Protocol and the subsequent Doha Amendment represent crucial milestones in international environmental efforts to establish binding emission reduction targets for the participating members. Many studies have examined the effects of the former, but not many the latter, on emissions reduction; however, their impact is inconclusive. One major reason may be due to the heterogeneous issue arising from the fact that countries ratified and implemented those agreements at different times. This study is the first to employ the staggered difference-in-difference method to analyse the two agreements within a unified framework. We empirically found that ratifying the Kyoto Protocol has significantly contributed to a decrease in global carbon dioxide emissions, although the impacts of the Doha Amendment are not statistically clear, underscoring the substantial role those agreements can play in protecting the global environment. Our findings are robust across several techniques, including the imputation estimator and the average group-time treatment approach.
