Digital echoes of heritage: toward a culturally balanced pedagogy in technology-enhanced bilingual education
Authors: Davoodi Amin 
Published: February 2024

Purpose
This study aims to investigate the integration of heritage language and culture in technology-enhanced bilingual education and examine the dominance of the English language and culture in computer-assisted language learning settings.

Design/methodology/approach
This research used a narrative inquiry methodology. The data came from semi-structured interviews with 25 bilingual teachers in the Kurdistan region of Iraq and Texas.

Findings
The study found a significant bias in the use of technology toward the target language, often at the expense of heritage language and culture. The curricula analyzed were predominantly focused on superficial cultural elements of the target language, leading to a neglect of deeper cultural engagement.

Originality/value
This research highlights the phenomenon of cultural cringe within bilingual education and the skewed use of technology toward the target language.
Ethnic diversity and homeownership
Authors: Awaworyi Churchill Sefa , Smyth Russell 
Published: February 2024

AbstractWe examine the impact of neighbourhood ethnic diversity on homeownership using 19 waves of household panel data from the Household, Income and Labour Dynamics in Australia survey. We find that ethnic diversity is associated with a lower probability of homeownership. Specifically, a movement from complete ethnic homogeneity to complete heterogeneity is associated with up to a 31.3 percentage point decrease in the probability of homeownership. Our results also show that trust, neighbourhood satisfaction and belongingness, which are lower in ethnically diverse neighbourhoods, are important channels through which ethnic diversity operates to reduce the probability of homeownership. We suggest policies to promote trust in multicultural societies with high levels of ethnic diversity with a view to addressing the negative relationship between ethnic diversity and homeownership.
A comparison of British and German parliamentary discourses on science diplomacy over time
Authors: Rüland Anna‐Lena , Rüffin Nicolas 
Published: February 2024

AbstractHow do members of parliament of different political parties discuss ‘science diplomacy’ – broadly speaking all activities at the intersection of science and foreign policy – on the parliamentary floor over time? We address this question against the backdrop of the Russian invasion of Ukraine in February 2022 and analyse 72 speeches on science and Russia from the German and British parliament between February 2014 and December 2022. Our analysis reveals similarities and differences in how science diplomacy is discussed in the German Bundestag and the British House of Commons, how party views on science diplomacy in relation to Russia differ and how said views change over time. In so doing, our study shows that national science and policy ecosystems with their specific institutions and actors shape science diplomacy debates, including in times of war.
Accountability in densely institutionalized governance spaces
Authors: Eilstrup‐Sangiovanni Mette , Hofmann Stephanie C. 
Published: January 2024

AbstractThe concept of organizational accountability is central to good governance both domestically and internationally. However, assessing accountability in densely institutionalized global governance spaces requires new conceptual and analytical tools. Rather than concentrating on the accountability of states, intergovernmental organizations (IGOs), non‐governmental organizations (NGOs), and transnational corporations as distinct sets of global actors to whom different accountability criteria and mechanisms may apply, we want to focus on how growing overlap and interplay among diverse global policy actors affects organizational accountability. And rather than focusing exclusively on accountability in terms of retrospective sanctioning based on fixed standards or legal obligations, we suggest that, in a densely institutionalized world, accountability also needs to be thought of as a prospective process. We therefore suggest a stronger focus on pluralistic, participatory, and deliberative forms of accountability that emphasize standard‐setting and responsiveness through collective deliberation, learning, and competition.

Published: February 2024

AbstractPersonality studies are increasingly relevant and applicable to a broad range of conservation issues, including a role for selecting compatible mates in conservation breeding programs (CBPs). Choosing compatible breeding pairs is essential for maximizing reproductive success in CBPs, which provide assurance populations for species facing extinction and candidates for translocation to support wild populations. We investigated the value of caretaker‐assessed personality ratings of the critically endangered ‘Alalā (Hawaiian Crow, Corvus hawaiiensis) in predicting reproductive outcomes: nest quality, fertile egg production, and hatchability in the ‘Alalā CBP. Caretakers used well‐defined operational definitions to rate 22 personality traits for 69 male and 59 female ‘Alalā, achieving high inter‐rater agreement (ICC ≥ 0.85) for 8 traits – aggressive, bold/fearless, fearful, imprinted/abnormal, inept, submissive, territorial, and tendency to feather pluck (a stereotypic behavior) – used in a principal components analysis to distill intercorrelated variables into three principal components. While we did not find that personality influences nest quality or hatchability (based on limiting inferences to fixed effects with high relative importance scores; ≥0.8), we found some evidence that pairs with males that were more territorial/aggressive and fearful than their mates had a higher probability of egg fertilization, but there was substantial variability in this relationship, with confidence intervals overlapping zero. These personality traits may influence pair dynamics, enhancing compatibility, may predict better pair coordination on the nest, or both. Our results highlight the ability of caretakers to successfully identify ‘Alalā personality traits and provide some support for integrating personality into the pairing process; however, further research is needed to understand the value of ‘Alalā personality as a mate selection tool. The application of similar approaches to enhance CBP performance in other taxa is promising, but will require overcoming methodological challenges surrounding the complexity of data collection and interpretation of consistency among raters.
Relationships among class climate, students' internal help‐seeking inclinations, participation in peer help and achievement in an online class
Authors: Huang Kun , Law Victor , Lee‐Post Anita 
Published: February 2024

AbstractHelp seeking has traditionally been studied in face‐to‐face settings using self‐report instruments measuring learners' internal inclinations for help seeking (eg, perceived benefits and threats). Much less is known about help seeking in online learning. Furthermore, external environmental factors such as a positive climate were found to encourage help seeking. Utilizing peer‐help analytics as well as self‐report measures, this study simultaneously modelled the structural relationships among students' perceived class climate, internal help‐seeking inclinations, help‐seeking engagement, participation in peer help and performance in an online class. Results from structural equation modelling indicated that students' perceived goal structure of an online class had a significant influence on their internal help‐seeking inclinations, which subsequently affected their help‐seeking engagement, participation in peer help and learning outcomes. Instructors of online classes should pay particular attention to fostering a mastery‐oriented climate in order to encourage help seeking and improve academic performance.
Practitioner notesWhat is already known about this topic

Help seeking is important for academic success.
Due to a variety of individual and contextual factors, students often do not seek help despite the need.
Existing research on help seeking focuses on the face‐to‐face setting and relies on self‐report measures.
Students' help‐seeking inclinations and patterns may differ between in‐person classes and the online environment.
What this paper adds

This study examined help seeking in an online class through self‐report measures and objective analytics data.
This study modelled the structural relationships among the external climate of an online class, students' internal help‐seeking inclinations, engagement in help seeking, participation in peer help and course performance.
Structural equation modelling found that the goal structure of an online class influenced students' internal help‐seeking inclinations.
Online students' internal help‐seeking inclinations affected their grades through their participation in help seeking.
Implications for practice and/or policy

A mastery‐oriented class climate elicits online learners' positive help‐seeking inclinations while discouraging negative ones.
The design and teaching of online classes should aim to foster a mastery‐oriented climate.
Online classes should offer peer‐help opportunities and encourage student participation, which is conducive to academic performance.
A review of the role played by cilia in medusozoan feeding mechanics
Authors: Jordano Mayara de A. , Nagata Renato M. , Morandini André C. 
Published: February 2024

ABSTRACTCilia are widely present in metazoans and have various sensory and motor functions, including collection of particles through feeding currents in suspensivorous animals. Suspended particles occur at low densities and are too small to be captured individually, and therefore must be concentrated. Animals that feed on these particles have developed different mechanisms to encounter and capture their food. These mechanisms occur in three phases: (i) encounter; (ii) capture; and (iii) particle handling, which occurs by means of a cilia‐generated current or the movement of capturing structures (e.g. tentacles) that transport the particle to the mouth. Cilia may be involved in any of these phases. Some cnidarians, as do other suspensivorous animals, utilise cilia in their feeding mechanisms. However, few studies have considered ciliary flow when examining the biomechanics of cnidarian feeding. Anthozoans (sessile cnidarians) are known to possess flow‐promoting cilia, but these are absent in medusae. The traditional view is that jellyfish capture prey only by means of nematocysts (stinging structures) and mucus, and do not possess cilia that collect suspended particles. Herein, we first provide an overview of suspension feeding in invertebrates, and then critically analyse the presence, distribution, and function of cilia in the Cnidaria (mainly Medusozoa), with a focus on particle collection (suspension feeding). We analyse the different mechanisms of suspension feeding and sort them according to our proposed classification framework. We present a scheme for the phases of pelagic jellyfish suspension feeding based on this classification. There is evidence that cilia create currents but act only in phases 1 and 3 of suspension feeding in medusozoans. Research suggests that some scyphomedusae must exploit other nutritional sources besides prey captured by nematocysts and mucus, since the resources provided by this diet alone are insufficient to meet their energy requirements. Therefore, smaller particles and prey may be captured through other phase‐2 mechanisms that could involve ciliary currents. We hypothesise that medusae, besides capturing prey by nematocysts (present in the tentacles and oral arms), also capture small particles with their cilia, therefore expanding their trophic niche and suggesting reinterpretation of the trophic role of medusoid cnidarians as exclusively plankton predators. We suggest further study of particle collection by ciliary action and its influence on the biomechanics of jellyfishes, to expand our understanding of the ecology of this group.

AbstractBackgroundMajor intracardiac thrombosis is an uncommon event during liver transplantation and has a high mortality rate. Given concerns for hemorrhage in liver transplantation with higher doses, low‐dose tissue plasminogen activator has been proposed as a treatment that rapidly leads to localized clot lysis and resolution of right ventricular failure.MethodsThis is a retrospective study using a prospectively collected database at the University of California at Los Angeles of liver transplant recipients from 2004‐2021. Adult patients who received tissue plasminogen activator for intracardiac thrombosis detected on transesophageal echocardiography were included.ResultsOut of 3236 liver transplants from 2016 to 2021, 11 liver transplant recipients were treated with intravenous low‐dose tissue plasminogen activator for major intracardiac thrombosis. The TPA dose range was 1–2.5 mg with three patients receiving more than one dose. All patients had severe hemodynamic instability. 90.9% of patients had right ventricular failure and 63.6% had cardiac arrest. After administration of low‐dose tissue plasminogen activator, 100% of patients had clinical improvement, clot resolution, and intraoperative survival, with 91% survival at 6 months post‐transplant. Adverse events included two patients with abdominal bleeding requiring re‐exploration and three patients having new intracranial hemorrhage which self‐resolved.ConclusionsLow dose tissue plasminogen activator was effective in treating major intracardiac thrombosis in our group of patients. Major complications included a limited number of hemorrhagic events.
Cortical linear encoding and decoding of sounds: Similarities and differences between naturalistic speech and music listening
Authors: Simon Adèle , Bech Søren , Loquet Gérard , Østergaard Jan 
Published: February 2024

AbstractLinear models are becoming increasingly popular to investigate brain activity in response to continuous and naturalistic stimuli. In the context of auditory perception, these predictive models can be ‘encoding’, when stimulus features are used to reconstruct brain activity, or ‘decoding’ when neural features are used to reconstruct the audio stimuli. These linear models are a central component of some brain–computer interfaces that can be integrated into hearing assistive devices (e.g., hearing aids). Such advanced neurotechnologies have been widely investigated when listening to speech stimuli but rarely when listening to music. Recent attempts at neural tracking of music show that the reconstruction performances are reduced compared with speech decoding. The present study investigates the performance of stimuli reconstruction and electroencephalogram prediction (decoding and encoding models) based on the cortical entrainment of temporal variations of the audio stimuli for both music and speech listening. Three hypotheses that may explain differences between speech and music stimuli reconstruction were tested to assess the importance of the speech‐specific acoustic and linguistic factors. While the results obtained with encoding models suggest different underlying cortical processing between speech and music listening, no differences were found in terms of reconstruction of the stimuli or the cortical data. The results suggest that envelope‐based linear modelling can be used to study both speech and music listening, despite the differences in the underlying cortical mechanisms.

Published: February 2024

AimsPlaque‐type blue naevi are rare melanocytic tumours presenting as large, pigmented plaques at birth or during childhood. There is a risk for malignant transformation, but no larger comprehensive studies exist and the diagnosis is challenging, especially on limited biopsy material. The aim is to describe the clinicopathological features and behaviour of the disease more comprehensively.Methods and resultsWe retrieved eight plaque‐type blue naevi, presenting as large, pigmented plaques (median = 7 cm; range = 3–26) most frequently affecting the scalp (four) followed by the cheek, arm, abdominal wall and gluteal cleft (one each), with a slight female predilection. Median age at time of biopsy was 39.5 years (range = 15–90), but three tumours had been present at birth and one since childhood. Histopathologically, the tumours were poorly circumscribed and composed of cellular fascicles of uniform spindle cells in a background of variably prominent pigmented dendritic cells affecting dermis and subcutaneous tissues. The majority had mutations in GNAQ. One tumour showed malignant transformation, characterised by an expansile nodule of pleomorphic epithelioid melanocytes with rhabdoid morphology, high mitotic activity and areas of necrosis. This patient developed metastatic melanoma to lymph nodes. All patients are alive with a median follow‐up of 60 months.ConclusionPlaque‐type blue naevi are diagnostically challenging tumours with risk for malignant transformation. Awareness and familiarity with the salient clinicopathological features are necessary for reliable diagnosis, and long‐term clinical follow‐up is required to monitor for malignant transformation.
Effect of chitosan combined with electrolyzed water on maintaining muscle quality and myofibril proteins of large yellow croaker (Pseudosciaena crocea) during refrigerated storage

SummaryThis study aimed to evaluate the effect of chitosan (CHI) combined electrolytic water (EW) cold sterilisation on muscle quality and myofibril proteins (MP) of large yellow croaker (Pseudosciaena crocea) during 12 days of refrigerated storage (4 °C). After the storage period, the sample of the EW + CHI group had the highest rate of hardness (36.68%), springiness (16.11%) among the control group without any treatment (CON), CHI group and EW group and similar tendencies were found in chewiness and cohesiveness. The MP content in the CON group decreased sharply from 80.35 mg g−1 to 57.90 mg g−1, in contrast to the EW + CHI group, which decreased from 81.65 mg g−1 initially to 80.83 mg g−1. The conformation of MP α‐helix and β‐sheet was retained to protect the secondary structure, and the exposure of aromatic amino acid residues was constrained to defend the tertiary structure in EW + CHI treatment which effectively delayed the degradation of MP. Based on these outcomes, EW + CHI treatment could significantly maintain the MP of large yellow croakers and prevent corruption during refrigerated storage.
An employee–employer relationship gone bad? Examining the double‐edged effect of psychological contract violation on employees' helping behaviors
Authors: Asante Eric Adom , Gyensare Michael Asiedu , El Bouzidi Laila , Twumasi Evelyn 
Published: February 2024

AbstractAn important concept that depicts the nature of employee–employer relationship is the psychological contract. Prior research has argued that all forms of extra‐role behaviors suffer once employees' psychological contracts are violated. Helping behaviors are a specific form of extra‐role behaviors that may suffer due to psychological contract violation. We argue that this predominantly negative relationship between psychological contract violation and helping behaviors is because the literature has not adequately examined the different types of helping behaviors. Using the latent moderated structural equation approach with multiwave and multisource data from a survey of 269 full‐time employees and their coworkers from the hospitality industry in Ghana, we show that psychological contract violation is positively related to reactive helping behaviors and negatively associated with anticipatory helping behaviors through anticipatory anxiety.

AbstractThe design of multifunctional materials with good thermophysical and electromagnetic shielding properties is desirable to overcome overheating and electromagnetic interference (EMI) in electronic devices. In this study, three‐dimensional (3D) continuous SiC skeleton‐reinforced highly oriented graphite flake (GF@SiC) composites were fabricated by combining molten salt synthesis, heat treatment, and spark plasma sintering. When the SiC content was higher than 9 vol.%, a 3D continuous SiC skeleton was formed, which effectively constrained the cross‐plane thermal expansion of the GF@SiC composites. Highly oriented GFs endowed the composites with good thermal conductivity (TC) along the basal plane and effective EMI shielding in the X‐band. The composites with SiC concentrations of 9 vol.% exhibited an optimal comprehensive performance with a high TC of 322 W/m/K in the basal plane direction, a low thermal expansion value of 10.5 × 10−6/K in the through‐plane direction, and EMI shielding effectiveness of 36 dB. Our strategy provides a promising and practical approach for realizing graphite‐based composites to meet the current demands for electronic devices.
Current rate flash sintering of nickel at ambient temperature in <1 min
Authors: Bamidele Emmanuel A. , Mahmoud Morsi M. , Raj Rishi 
Published: January 2024

AbstractWe show that powder pressed specimens of nickel can be sintered to 99.96% density by injecting electrical current, without the use of a furnace. Full sintering could be accomplished in 10 to 52 s by changing the current rate from 5 to 1 A/s. In all instances, the samples sintered abruptly at a current density of ∼20 A mm−2. The grain size of the sintered samples was somewhat larger than the nickel powder particle size (∼60 μm vs. 40 μm). Tensile testing yielded a yield strength of 98 MPa, ultimate tensile stress of 323 MPa, and ductility of ∼17%. Four in‐operando measurements are reported: (i) sintering, (ii) the change in resistance with current density, (iii) the temperature, and (iv) electroluminescence. The change in resistance during flash sintering exhibited a high peak followed by a steep decline in resistance; the transient is attributed to the breakdown of particle–particle interface resistance. The same cycle repeated with the flash‐sintered, dense sample, did not show the spike, and gave reproducible results. The resistance data for these latter cycles, when viewed as a function of temperature exhibited sigmoidal behavior: initially lower, and then higher than the literature values. This unusual behavior reflects the influence of defects generated during flash. We have also measured the endothermic enthalpy, expressed by the difference between the in situ input electrical energy and the radiation, convection, and specific heat losses. Dividing by the formation energy of Frenkel pairs yields the concentration of defects, estimated to be 0.3–0.4 mol %. These concentrations are far above thermal equilibrium; it is concluded that flash of metals is a far from equilibrium phenomenon.
