Whether bilingualism confers non-linguistic cognitive advantages continues to generate both interest and debate in the psychological sciences. In response to mixed reports and methodological critiques, researchers have embraced more rigorous practices when investigating bilingual effects, including those in the domain of cognitive control. Despite considerable advances, one significant issue persists: the assumption that task performance remains stable over time. To address this, the present study investigated the relationship between bilingual language experience and Simon task performance modeled as a continuous function of time. In a sample of Mandarin-English bilingual young adults, we identified distinct patterns of results across both conventional and time-sensitive performance trajectory measures with each supporting a different relationship between language experience and cognitive control. Results suggest that reliance on conventional performance measures may be partially responsible for mixed results, necessitating reevaluation of how bilingual effects on cognitive control manifest and which analysis methods best support their identification.
While empathy is often seen as a resilience factor, emotional resonance with others’ suffering may increase psychological vulnerability during mass trauma exposure, particularly in youth. Since the role of early empathy as a prospective risk factor remains understudied, we used a decade-long longitudinal design to examine whether empathic reactions in childhood predicted early adolescents’ internalizing (depression and anxiety) symptoms following the October 7th attack and the Israel–Hamas war. Empathic distress was assessed at age 1.5 years and age 3 years through observational tasks. Emotional empathy and internalizing symptoms were self-reported at age 11 years, before the war, and reported again after its outbreak. Findings showed substantial internalizing symptoms during the war, with 31% of participants exceeding the clinical cutoff for anxiety and 23% for depression. Non of the empathy measures predicted internalizing symptoms before the war. However, during the war, empathic distress at age 1.5 and emotional empathy at age 11 predicted internalizing symptoms, controlling for negative emotionality and prior internalizing symptoms. Path analysis also linked empathic distress at age 3 to internalizing symptoms during war. Findings suggest that early empathic reactions may increase vulnerability to internalizing symptoms during mass trauma but not in non-traumatic contexts, aligning with a diathesis-stress model. Understanding empathy’s role in risk and resilience can inform interventions for youth exposed to war.
Fiber-coupled laser pumps with low size, weight and power consumption (SWaP) have become more and more compelling for applications in both industrial and defense applications. This study presents an innovative approach employing the spectral beam combining technique and double-junction laser diode chips to create efficient, high-power, high-brightness fiber-coupled packages. We successfully demonstrated a wavelength-stabilized pump module capable of delivering over 560 W of ex-fiber power with an electro-optical conversion efficiency of 55% from a 135 μm diameter, 0.22 numerical aperture fiber. The specific mass and volume metrics achieved are 0.34 $\mathrm{kg}/\mathrm{kW}$ and 0.23 ${\mathrm{cm}}^3/\mathrm{W}$, respectively. The module exhibits a stabilized spectrum with a 3.6 nm consistent interval of two spectral peaks and a 4.2 nm full width at half maximum across a wide range of operating currents.
We lay down the foundations of the Eigenvalue Method in coding theory. The method uses modern algebraic graph theory to derive upper bounds on the size of error-correcting codes for various metrics, addressing major open questions in the field. We identify the core assumptions that allow applying the Eigenvalue Method, test it for multiple well-known classes of error-correcting codes, and compare the results with the best bounds currently available. By applying the Eigenvalue Method, we obtain new bounds on the size of error-correcting codes that often improve the state of the art. Our results show that spectral graph theory techniques capture structural properties of error-correcting codes that are missed by classical coding theory approaches.
The concept of beneficial ownership is extensively used in domestic tax legislation, but several decades of inconsistent case law have muddied the waters as to exactly what it means. With the leading cases stopping short of the apex court, it is difficult to reconcile the cases and come up with a clear definition of beneficial ownership. The recent Hargreaves1 decision by Falk LJ (with whom Nugee and Peter Jackson LJJ agreed) represents the most structured judicial attempt to rationalise the concept to date. This note suggests that, contrary to Falk LJ’s statement that the concept is ‘well established’,2 the law pre-Hargreaves was far from clear. This situation has since been greatly improved through the efforts of Falk LJ, though further questions remain for future judicial clarification.
Steady flow at low Reynolds (Re) number through a planar channel with converging or diverging width is investigated in this study. Along the primary direction of flow, the small dimension of the channel cross-section remains constant while the sidewalls bounding the larger dimension are oriented at a constant angle. Due in part to ease of manufacturing, parallel-plate geometries such as this have found widespread use in microfluidic devices for mixing, heat exchange, flow control and flow patterning at small length scales. Previous analytical solutions for flows of this nature have required the converging or diverging aspect of the channel to be gradual. In this work, we derive a matched asymptotic solution, validated against numerical modelling results, that is valid for any sidewall angle, without requiring the channel width to vary gradually. To accomplish this, a cylindrical coordinate system defined by the angle of convergence between the channel sidewalls is considered. From the mathematical form of the composite expansion, a delineation between two secondary flow components emerges naturally. The results of this work show how one of these two components, originating from viscous shear near the channel sidewalls, corresponds to convective mixing, whereas the other component impresses the sidewall geometry on streamlines in the outer flow.
An adolescent girl with a long-standing history of pulmonary arterial hypertension experienced severe clinical decompensation after starting to use e-cigarettes. A combination of e-cigarette cessation, atrial septostomy, increasing treprostinil, and initiation of sotatercept led to clinical improvement. Her new baseline was improved over her pre-e-cigarette baseline.
The high comorbidity of substance use disorders (SUDs) among people with severe mental health conditions (MHCs) poses major challenges to providing effective care, particularly in low- and middle-income countries (LMICs), where treatment options are limited.
Aims
The aim of this scoping review was to produce an overview of the current evidence on psychosocial interventions for people with comorbid MHCs and SUDs in LMICs.
Method
The following databases were searched from their inception to 23 July 2024: PubMed/Medline, Global Health, Embase, PsycINFO and Global Index Medicus. We also searched for grey literature, using Google Scholar, ProQuest and Clinicaltrials.gov. Reporting was according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) Checklist. Studies were eligible if they focused on any psychosocial intervention targeting substance use in people with severe MHCs from LMICs. Of the 6304 records screened by titles and abstracts, 138 full-text articles were assessed and included for data extraction.
Results
Of the 6304 records screened by titles and abstracts, 138 full-text articles were assessed and 13 articles were included for data extraction. Many of the studies (n = 9) had a quasi-experimental design, and were from Latin America and South Asia. Four studies were randomised controlled trials. The primary outcomes examined were substance use abstinence, treatment engagement and retention, reduction in psychiatric symptoms, functioning and suicidal behaviours. Despite some heterogeneity in study designs, target populations and evaluated outcomes, interventions including various tobacco cessation programmes, screening and brief intervention with family support, and community-based programmes, have demonstrated positive outcomes in reducing tobacco, alcohol and khat use, respectively.
Conclusions
The review shows that there have been few initiatives to design and test psychosocial interventions for individuals with comorbid severe MHCs and SUDs in LMICs. There is a clear need to design and test feasible, acceptable, and effective interventions to address both severe MHCs and substance use when they co-occur.
Palmer amaranth and waterhemp are troublesome weeds in U.S. corn, soybean, and cotton production systems. Rapid evolution of resistance to herbicide from multiple sites of action in these species warrant alternate weed control options. Metribuzin applied preemergence can provide effective control of herbicide-resistant Amaranthus species. However, despite its decades of efficacy, many growers remain unaware of its weed control potential or are hesitant to use it due to concerns over crop injury. Field experiments were conducted in 2022 and 2023 in 15 states across the United States to investigate residual control of Palmer amaranth and waterhemp with metribuzin applied preemergence to soybean. Sites had either herbicide-resistant Palmer amaranth or waterhemp as the dominant weed species. Seventeen preemergence treatments were evaluated, including 13 doses of metribuzin (210 to 841 g ai ha-1), a dose of sulfentrazone (420 g ai ha-1), and a dose of S-metolachlor (1,790 g ai ha-1), along with nontreated and a weed-free control plots. Weed control and soybean injury were visually assessed and recorded at 14, 28, and 42 d after application (DAA) of preemergence herbicides. Additionally, weed density, weed biomass, and soybean height were recorded 28 DAA followed by a measure of soybean yield at maturity. Weed control was analyzed as a function of metribuzin dose and environmental factors using a generalized additive model. Crop injury of not more than 5% was predicted even with 841 g ai ha-1 of metribuzin. Metribuzin at 630 g ai ha-1 was more effective than sulfentrazone in delaying weed emergence and reducing weed density, while 315 g ai ha-1 of metribuzin outperformed S-metolachlor in both metrics. Metribuzin doses of 578 to 841 g ai ha-1 provided greater than 95%, 90%, and 80% weed control, respectively, at 14, 28, and 42 DAA. Higher metribuzin doses of 578 to 841 g ai ha-1could be safely to effectively control herbicide-resistant Amaranthus weeds.
The erosion of coastal archaeological sites is a worldwide heritage crisis. However, regional variability in the archaeological record and the natural environment necessitates localized consideration of the erosion of archaeological sites to facilitate informed research prioritization decisions about coastal cultural resources. In this article, we present and compare the results of recent coastal survey programs from southern Nova Scotia and far northeastern Maine to earlier ones to ascertain the extent of erosion since the mid-twentieth century. We then situate regional erosion in culture-historical terms via a case study from archaeological sites at Sipp Bay, Maine, from which materials were collected and tested in the early to mid-twentieth century. We compare the results of that work to our recent excavations. Finally, we model future sea-level rise scenarios to estimate future site destruction and compare these models between regions. Together, these data illustrate patterns in site preservation for geoarchaeological examination, provide insight into erosion-driven biases in the extant archaeological record, and offer information to guide research prioritization.
To identify and present (i) how responsibility for poor diets in the UK is framed across the public, mass media and the government and (ii) how groups experiencing socio-economic disadvantage are presented within this framing.
Design:
A scoping review of peer-reviewed literature was conducted using six databases. A systematic narrative synthesis guided by qualitative content analysis was applied to summarise the findings.
Results:
Thirty-six articles were included. Studies exploring public perceptions of poor diets acknowledged personal and broader systems drivers, with individual responsibility predominating across studies. Research analysing media portrayals showed similar patterns of individual responsibility among right-leaning newspapers, which focused on individual lifestyle changes. However, left-wing newspapers highlighted the role of the food industry and the government. Studies analysing government policies identified citizens as the primary agents of change through rational decision-making. Framing from socio-economically disadvantaged groups showed a preference for prioritising their own choice, but were limited by household income, food prices and family food preferences. Policies and media portrayals provided limited emphasis on these populations, with individual responsibility narratives prevailing.
Conclusions:
The framing of responsibility for poor diets in the UK centred on the individual, obscuring the powerful influence of food manufacturers and retailers and the role of government in providing safe, healthy environments for all. This review highlights the urgent need to challenge this narrative, with the public health nutrition community working collectively to force a radical shift in public, media and policy framing and incite strong regulatory action by governments.
In a pioneering effort, this research presents a distinctive transformation of the Government College University Faisalabad (GCUF) logo into an RFID tag antenna using characteristic mode analysis (CMA), which resonates at the entire ultra-high frequency (UHF) radio frequency identification (RFID) band for IoT applications. The logo of GCUF is simulated in a computer simulation technology (CST) microwave studio to execute its four characteristic modes at 900 MHz. With the implementation of minor changes in the GCUF logo, optimal conjugate impedance matching with the RFID chip has been achieved. The impedance, reflection coefficient, and far-field pattern are examined through CST. The logo tag antenna is fabricated using a Rexin substrate (artificial leather) coated with conductive paint and a passive UHF RFID Alien Higgs H3 chip attached to the logo for impedance matching. The proposed design has been simulated with a human body model. The read range of the fabricated prototype is tested on different objects, like a notebook, T-shirt, and bag. The measured read range demonstrates the robustness of the proposed logo design across various distances: 3 m for a notebook and bag, and 2 m for a T-shirt, with RSSI values of −61 dB, −59 dB, and −62 dB, respectively.
We present research from Visual World eye tracking to show that, contrary standard assumptions in the formal semantics literature, the English past tense does not reliably trigger entailments of completion on accomplishments in neutral contexts. We contrast it with the perfect construction in English (both present and past tense versions) which does reliably draw attention to the result state; furthermore, we tested the simple past in more narrative contexts (using adverbial clauses to create a narrative sequence) and found that this did not induce a stronger resultative interpretation. We discuss the formal proposals for analysis of these tense/aspect forms in the language, and the consequences this new data has for theories of the tense/aspect system of English.
Assessing the long-term impact of community-engaged research (CEnR) programs remains a significant challenge in translational science, such as those conducted by Clinical and Translational Science Awards (CTSAs). The Translational Science Benefits Model (TSBM) is a framework designed to evaluate impact across four health and social domains (clinical/medical, community, economic, and political/legislative). TSBM offers a comprehensive framework for evaluating CEnR projects, as it extends beyond short-term outcomes to highlight distal impacts and sustainable benefits. Progress reports from three Cincinnati CTSA CEnR programs (Community Leaders Institute [CLI; n = 170], Community Health Grant [CHG; n = 82], and Partnership Development Grant [PDG; n = 21]) completed between 2010 and 2023 were coded by three reviewers using the TSBM. As expected, CEnR programs primarily demonstrated community & public health benefits. Economic, policy, and clinical benefits were also identified, further amplifying the impact of this work. The adoption of frameworks like the TSBM could lead to a more standardized approach for evaluating the impact of CEnR programs and facilitate comparisons across CTSAs. Future studies that track the impact of CEnR programs on health and social systems could provide valuable insights into the long-term benefits of these initiatives.
To tailor an existing Person-Centred Integrated Care (PC-IC) approach to the needs of patients with low socioeconomic status (LSES) and chronic conditions in primary care.
Background:
While Disease Management Programs (DMPs) have been introduced to reduce the burden of chronic diseases, their effectiveness for patients with LSES remains uncertain due to insufficient attention to the individual context. A PC-IC approach may enhance patient outcomes by addressing patients’ cultural backgrounds, values, and health literacy needs, because these factors are particularly relevant for patients with LSES.
Method:
A qualitative study was conducted using three co-creation sessions with patients with LSES and chronic conditions, along with general practitioners and practice nurses, to adapt, develop, and test specific elements of the PC-IC approach. Participatory learning and action (PLA) techniques incorporating visual materials were employed to ensure meaningful engagement and input by all participants, including those with limited reading and language skills. Following these sessions, we conducted a validation check by patients on the draft materials.
Findings:
In the co-creation sessions, an existing PC-IC approach was tailored to the needs of LSES patients with chronic conditions in primary care. The adapted PC-IC approach emphasized key elements as trust, being seen as a person in the social context, shared decision-making, and access to clear and easily understandable information. Existing materials needed to be adapted, resulting in a visual conversation tool. This tool covers the physical, social, and mental health domains as well as daily life, each domain with six to eight topics. It helps to get better insight into the patient’s daily life, wishes, and possibilities. It maps medical and psychosocial issues and supports the patient in gaining a better understanding. The adapted PC-IC approach with the conversation tool is being presented in a training for primary care professionals.
Ageing is often framed through the lens of independence, with a strong emphasis on not burdening younger family members. Little attention, however, has been given to how this framing reflects and reinforces age inequality by devaluing older adults relative to younger ones. Drawing on semi-structured interviews with 43 Italians aged 65 and older, conducted in 2018/2019 and 2022, we identify an orientation we term ‘altruistic ageing’ – a perspective that centres younger people’s needs by expecting older adults to adopt a selfless concern for others’ wellbeing. This orientation emerged in participants’ definitions of burden, which centred on receiving long-term or intensive assistance or co-residing with younger family members. These definitions reflected a privileging of younger adults’ time, personal freedom, social relationships and commitment to paid work. Altruistic ageing had consequences: It encouraged healthy behaviours but also narrowed acceptable long-term care options and constrained definitions of a ‘good death’. By unpacking the framing of older adults as burdens, our study reveals how age inequality operates through a culturally sanctioned ideal that morally justifies prioritizing the young over the old.
Learners completing writing tasks in pairs or small groups engage in peer interaction, operationalized as language-related episodes (LREs), which seem to facilitate second or foreign language (L2) acquisition. Multiple studies have shown that the patterns of interaction learners form during collaborative language tasks affect the frequency, nature, and outcome of LREs, as well as the quality of the written texts. However, most findings come from studies involving young and adult learners of English as a foreign or a second language (EFL/ESL), whereas research with adolescent EFL learners (aged 13–15) remains scarce. Given the widespread presence of L2 instruction in compulsory education and adolescents’ unique developmental traits, further research is crucial. This study addresses this gap by examining the patterns of interaction, the number, type, and outcome of LREs, and the written texts produced by 60 adolescent EFL learners (aged 13–14) completing a writing task in pairs. Results showed that adolescent learners formed predominantly collaborative patterns of interaction, followed by expert/novice, dominant/dominant, and dominant/passive. Additionally, the pairs with collaborative orientation produced and correctly resolved more LREs and created higher quality texts, measured through global evaluation rubrics. These findings underscore the importance of fostering collaborative pair work in L2 classrooms to enhance peer interaction, LREs, and writing quality.
To date, little is known about the evidence of a potential risk of psychiatric adverse events following COVID-19 vaccination in large populations with adequate study design.
Aims
To investigate whether COVID-19 vaccination is associated with increased risk of psychiatric adverse events.
Method
We used South Korea’s linkage database to obtain registry data and claims data from 2019 to 2021, and conducted a population-based self-controlled case series study including 11 751 806 individuals. Primary outcomes included anxiety/nervousness, mood disorders, perceptual disturbances/psychoses, aggression/behavioural disturbances, cognitive impairments and sleep disorders within 21 days of COVID-19 vaccination. Secondary outcomes were the stratified primary outcomes according to each individual’s psychiatric history. Conditional Poisson regression was used to estimate incidence rate ratios (IRR) and 95% confidence intervals.
Results
COVID-19 vaccination did not increase the rate of anxiety and nervousness (adjusted IRR 0.95, 95% CI 0.95–0.96), mood disorders (adjusted IRR 0.75, 95% CI 0.75–0.76), perceptual disturbances and psychoses (adjusted IRR 0.72, 95% CI 0.70–0.74), aggression and behavioural disturbances (adjusted IRR 0.93, 95% CI 0.89–0.97), cognitive impairment (adjusted IRR 0.68, 95% CI 0.67–0.69) or sleep disorders (adjusted IRR 0.90, 95% CI 0.89–0.91). Secondary outcomes were consistent with the primary outcome, although the adjusted IRRs for anxiety and nervousness (adjusted IRR 1.17, 95% CI 1.15–1.18) and sleep disorders (adjusted IRR 1.07, 95% CI 1.06–1.09) were statistically significant in individuals with no history of psychiatric disorders. Sensitivity analyses showed consistent results with our main findings.
Conclusions
Our findings provide short-term safety profiles for COVID-19 vaccines regarding psychiatric adverse events. Continuous monitoring of anxiety/nervousness or sleep disorders after COVID-19 vaccination is required regardless of history of psychiatric comorbidities.
Social function is increasingly demonstrated as a factor in risk, maintenance and outcome of eating disorders, but not emphasised in theoretical models of, and treatment approaches to, adolescent eating disorders.
Aims
To adapt Schmidt and Treasure’s cognitive interpersonal model of anorexia nervosa to incorporate developmental and transdiagnostic components.
Method
Qualitative interviews with young people aged 12–16 years (inclusive), who are in contact with child and adolescent community eating disorders services, and their parents, subjected to thematic analysis.
Results
Five key themes emerged that were mutually dependent on a sixth theme of emotion regulation and coping. These themes were: peer relationships, change and uncertainty, thinking styles, appearance and achievement-based values, and family relationships.
Conclusions
Peer relationships emerged as distinct from family relationships in this population, and a unifying theme was emotion regulation and coping. The framework could guide clinical assessment and the development or adaptation of interventions to address the themes identified. Research is needed to understand the role of the themes in treatment response and outcomes.
The objective of this study is to analyze the debate surrounding the transformation of the Bank of Brazil into a central bank in 1923. The article seeks to answer the question: What was the role of a central bank for Brazilian policymakers at that time? Unlike other Latin American countries that established their central banks during this period, Brazil’s institution was not the result of any foreign mission. While central banks in other countries were primarily concerned with maintaining the gold standard, in Brazil, the main impetus for establishing a central bank was the need to address cash shortages and expand credit, rather than focusing on monetary discipline. Advocates for the creation of a central bank in Brazil were inspired by the model of Germany’s Reichsbank, and part of their theoretical influence came from the German Historical School. Other references cited in the debates included the works of Keynes and Cassel, and the participants of the debate made parallels with other sciences, such as comparing the central bank to elements of mechanical physics. Beyond controlling the money supply, the central bank was seen as an element for the economic development of the country, and there was an emphasis on the bank’s private management.
