Potential integration of Chinese and European emissions trading market: welfare distribution analysis
Authors: Li Ru , Perdana Sigit , Vielle Marc
Published: June 2021

Central to the aims of the Paris Agreement, an integrated carbon market could potentially be a practical bottom-up option for effective and efficient mitigation. This paper quantifies the welfare effects of integration of Emission Trading Scheme (ETS) between the European Union (EU) and China. Using the European version of the computable general equilibrium model GEMINI-E3, our assessment reveals that integrating trading markets benefits both regions through the decrease welfare costs from abatements. China’s welfare improves through net gain of selling the allowance, while the EU experiences lower deadweight loss. This effect is stronger to some notable countries in the EU, with high energy-intensive industries such as Poland and the Czech Republic. While a few others, such as Netherlands and Ireland, face higher welfare costs from negative trade gain. Limiting the trade quotas to 40% captures most of the EU welfare gain coming from CO2 trading. Further analysis at the sectoral level reveals that market integration significantly minimizes the loss of competitiveness of European energy-intensive industries and reduces international leakage. Our finding thus confirms the potential of the emissions trading market as an effective instrument to facilitate multilateral coordination in global mitigation.

Published: June 2021

Modeling flow in vegetative fuel beds is a key component in any detailed physics-based tool for simulating wildland fire dynamics. Current approaches for drag modeling, particularly those employed in multiphase computational fluid dynamics (CFD) models, tend to take a relatively simple form and have been applied to a wide range of fuel structures. The suitability of these approaches has not been rigorously tested for conditions which may be encountered in a wildland fire context. Here, we focus on beds ofPinus rigidaneedle litter and undertake a two-part study to quantify the drag and evaluate the capabilities of a multiphase large eddy simulation CFD model, the NIST Fire Dynamics Simulator. In the first part, bed drag was measured in a wind tunnel under a range of conditions. The results were fit to a Forchheimer model, and the bed permeability was quantified. A traditional approach employed in the multiphase formulation was compared to the parameterized Forchheimer equation and was found to over-predict the drag by a factor of 1.2–2.5. In the second part, the development of a velocity profile above and within a discrete fuel layer was measured. Using the Forchheimer equation obtained in the first part of the study, the CFD model was able to replicate a qualitatively consistent velocity profile development. Within the fuel bed, the model appeared to under-predict the velocity magnitudes, which may be the result of unresolved pore-scale flow dynamics.

Epstein-Barr virus (EBV) T/NK-cell lymphoproliferative diseases are characterized by clonal expansion of EBV-infected T or NK cells, including chronic active EBV infection of T/NK-cell type (CAEBV+T/NK), EBV-associated hemophagocytic lymphohistiocytosis (EBV+HLH), extranodal NK/T-cell lymphoma of nasal type (ENKTL), and aggressive NK-cell leukemia (ANKL). However, the role of inherited genetic variants to EBV+T/NK-LPDs susceptibility is still unknown. A total of 171 nonimmunosuppressed patients with EBV+T/NK-LPDs and 104 healthy donors were retrospectively collected and a targeted sequencing study covering 15 genes associated with lymphocyte cytotoxicity was performed. The 94 gene variants, mostly located in UNC13D, LYST, ITK, and PRF1 genes were detected, and mutations covered 28/50 (56.00%) of CAEBV-T/NK, 31/51 (60.78%) of EBV+HLH, 13/28 (46.42%) of ENKTL, and 13/48 (27.09%) of ANKL. Most mutations represented monoallelic and missense. Three-year overall survival rate of patients with CAEBV-T/NK and EBV+HLH was significantly lower in patients with germline mutations than in those without germline mutations (P=0.0284, P=0.0137). Our study provided novel insights into understanding a spectrum of nonimmunosuppressed EBV+T/NK-LPDs with respect to genetic defects associated with lymphocyte cytotoxicity and reminded us that the gene sequencing may be an auxiliary test for diagnosis and risk stratification of EBV+T/NK-LPDs.

Published: June 2021

This study investigates the use of glass fiber-reinforced polyester (GRP) pipe powder (PP) for improving the bearing capacity of sandy soils. After a series of direct share tests, the optimum PP addition for improving the bearing capacity of soils was found to be 12%. Then, using the optimum PP addition, the bearing capacity of the soil was estimated through a series of loading tests on a shallow foundation model placed in a test box. The bearing capacity of sandy soil was improved by up to 30.7%. The ratio of the depth of the PP-reinforced soil to the diameter of the foundation model (H/D) of 1.25 could sufficiently strengthen sandy soil when the optimum PP ratio was used. Microstructural analyses showed that the increase in the bearing capacity can be attributed to the chopped fibers in the PP and their multiaxial distribution in the soil. Besides improving the engineering properties of soils, using PP as an additive in soils would reduce the accumulation of the industrial waste, thus providing a twofold benefit.
Turbulence model performance for ventilation components pressure losses
Authors: Tawackolian Karsten , Kriegel Martin
Published: June 2021

This study looks to find a suitable turbulence model for calculating pressure losses of ventilation components. In building ventilation, the most relevant Reynolds number range is between 3×104and 6×105, depending on the duct dimensions and airflow rates. Pressure loss coefficients can increase considerably for some components at Reynolds numbers below 2×105. An initial survey of popular turbulence models was conducted for a selected test case of a bend with such a strong Reynolds number dependence. Most of the turbulence models failed in reproducing this dependence and predicted curve progressions that were too flat and only applicable for higher Reynolds numbers. Viscous effects near walls played an important role in the present simulations. In turbulence modelling, near-wall damping functions are used to account for this influence. A model that implements near-wall modelling is the lag elliptic blendingk-εmodel. This model gave reasonable predictions for pressure loss coefficients at lower Reynolds numbers. Another example is the low Reynolds numberk-εturbulence model of Wilcox (LRN). The modification uses damping functions and was initially developed for simulating profiles such as aircraft wings. It has not been widely used for internal flows such as air duct flows. Based on selected reference cases, the three closure coefficients of the LRN model were adapted in this work to simulate ventilation components. Improved predictions were obtained with new coefficients (LRNM model). This underlined that low Reynolds number effects are relevant in ventilation ductworks and give first insights for suitable turbulence models for this application. Both the lag elliptic blending model and the modified LRNM model predicted the pressure losses relatively well for the test case where the other tested models failed.
Children’s Imaginaries of Robots for Playing With

Published: June 2021

Children with severe motor impairment due to cerebral palsy have difficulties engaging in play, although they want to play games that typically developing children play. The barriers imposed by motor impairments against engaging in play can be addressed through the use of robots. We aim to identify how children, who have extensive experience of play, imagine what a robot is and what features would make a robot good to play with. Using a qualitative description design, 19 children from urban and rural settings participated in focus groups to draw and talk about the robots they would like to exist. The data were coded and analyzed using a summative approach to content analysis. The findings revealed that the children imagined that a good robot to play with is one that has an anthropomorphic appearance, is tough and strong, has controls, and that is able to move, grab, speak, and play popular children’s games. In particular, the girls imagined that robots should be able to express positive emotions towards children. Age, gender, culture, and the physical environment in which the children lived influenced what they expected to find in a robot for playing with and how they imagined child–robot interactions.
Multi-task Pruning via Filter Index Sharing: A Many-Objective Optimization Approach
Authors: Cheng Hanjing , Wang Zidong , Ma Lifeng , Liu Xiaohui , Wei Zhihui
Published: June 2021

State-of-the-art deep neural network plays an increasingly important role in artificial intelligence, while the huge number of parameters in networks brings high memory cost and computational complexity. To solve this problem, filter pruning is widely used for neural network compression and acceleration. However, existing algorithms focus mainly on pruning single model, and few results are available to multi-task pruning that is capable of pruning multi-model and promoting the learning performance. By utilizing the filter sharing technique, this paper aimed to establish a multi-task pruning framework for simultaneously pruning and merging filters in multi-task networks. An optimization problem of selecting the important filters is solved by developing a many-objective optimization algorithm where three criteria are adopted as objectives for the many-objective optimization problem. With the purpose of keeping the network structure, an index matrix is introduced to regulate the information sharing during multi-task training. The proposed multi-task pruning algorithm is quite flexible that can be performed with either adaptive or pre-specified pruning rates. Extensive experiments are performed to verify the applicability and superiority of the proposed method on both single-task and multi-task pruning.
Professional Development in Arts Education for Early Childhood Education: A Creative Exchange Model
Authors: Hayes Nóirín , Maguire Jacqueline , O’Sullivan Carmel
Published: June 2021

This paper reports a model for professional development for early childhood arts education. The research delivered a co-mentoring programme between early years teachers and artists, which applied a process of ‘creative exchange’, in which across a period of 2 years, 12 educators and two teaching artists participated. Common principles underpinning early childhood education and arts education include recognition of the critical role of early experiences and relationships and quality learning opportunities as foundations for positive child development. Using these common principles, early childhood educators and artists worked together as equals to provide an enriched early learning environment with improved use of space and materials in an atmosphere of “unhurried time”. Themes in the evaluation of the professional outcomes for educators and artists included increased engagement with the arts; changes in pedagogy; building relationships between artists and educators; and the importance of making time for reflection and planning. The creative exchange process led to positive changes in practice and strengthened understandings, for both educators and artists, of the capabilities of young children.
Risk assessment of pollution with heavy metals in water and fish from River Nile, Egypt
Authors: Ghannam Hala E.
Published: June 2021

The aim of this study is to investigate the level of contamination with metals (Fe, Mn, Zn, Cu, and Pb) in the Nile River at the great Cairo region. Samples of water and fish were collected seasonally from different sites along the investigated area. Physical and chemical parameters of the studied water samples such as temperature, transparency, electrical conductivity, pH, BOD, and COD were measured. In aquatic ecosystems, heavy metal concentrations are monitored by detecting some indices like water pollution indices (WPI) and bioaccumulation factor (BAF). The results clarified that Fe, Pb, and Mn concentrations in water exceed the allowed limits set by WHO, 2011 in all sites while Cu and Zn are in allowed limits. While in fish muscle Fe and Cu are within the permissible limits set by FAO, 1992, but Mn, Zn and Pb exceed the limits. Some of the metals like Cu, Fe, Mn, Ni and Zn are essential for animals and plants while many other like Pb, Cd, Cr and Co are classed as nonessential metals. All values of HI were below 1 except for Pb in case of habitual fish eaters that give alarm to fish consumer.
Where are we now? Emerging opportunities and challenges in the management of secondary hyperparathyroidism in patients with non-dialysis chronic kidney disease
Authors: Ketteler Markus , Ambühl Patrice
Published: June 2021

Rising levels of parathyroid hormone (PTH) are common in patients with chronic kidney disease (CKD) not on dialysis and are associated with an elevated risk of morbidity (including progression to dialysis) and mortality. However, there are several challenges for the clinical management of secondary hyperparathyroidism (SHPT) in this population. While no recognised target level for PTH currently exists, it is accepted that patients with non-dialysis CKD should receive early and regular monitoring of PTH from CKD stage G3a. However, studies indicate that adherence to monitoring recommendations in non-dialysis CKD may be suboptimal. SHPT is linked to vitamin D [25(OH)D] insufficiency in non-dialysis CKD, and correction of low 25(OH)D levels is a recognised management approach. A second challenge is that target 25(OH)D levels are unclear in this population, with recent evidence suggesting that the level of 25(OH)D above which suppression of PTH progressively diminishes may be considerably higher than that recommended for the general population. Few therapeutic agents are licensed for use in non-dialysis CKD patients with SHPT and optimal management remains controversial. Novel approaches include the development of calcifediol in an extended-release formulation, which has been shown to increase 25(OH)D gradually and provide a physiologically-regulated increase in 1,25(OH)2D that can reliably lower PTH in CKD stage G3–G4 without clinically meaningful increases in serum calcium and phosphate levels. Additional studies would be beneficial to assess the comparative effects of available treatments, and to more clearly elucidate the overall benefits of lowering PTH in non-dialysis CKD, particularly in terms of hard clinical outcomes.

Community-Based Interventions for the Treatment and Management of Conflict-Related Trauma in Low-Middle Income, Conflict-Affected Countries: a Realist Review
Authors: Al-Tamimi Saleh Adel G. A. , Leavey Gerard
Published: June 2021

Where low- and middle-income countries have limited economic resources to provide individualized mental health services to people exposed to conflict, community-based interventions may be more appropriate. We aimed to evaluate community level interventions for improving mental health outcomes in Low- and Middle-income countries (LMIC). A realist review of community-based interventions (CBIs) to improve mental health for people in LMIC following conflict. Five databases (Cochrane, PubMed, PsychINFO, Medline, and CINAHL) and a manual search of individual papers. We found 1318 articles, of which 29 were selected. Out of the 29 primary articles, 19 showed successful results, 4 showed mixed results, 1 showed inconclusive results, and 1 showed unsuccessful results. After analyzing the results, we found 3 mechanisms that may influence the effectiveness of these CBIs: the use of lay community members as intervention deliverers, the application of transdiagnostic approaches, and customized outcome assessment tools. Community-based approaches to improve mental health in LMICs are rare and evidence for their effectiveness is limited. Interventions that have a wide scope, train lay mental health workers, and use contextually adapted outcome assessment tools show promise.
Representing the Unseen with “Our Journey”: a Platform to Capture Affective Experiences and Support Emotional Awareness in University-Level Study
Authors: Coughlan Tim , Lister Kate , Lucassen Mathijs
Published: June 2021

Student mental health is a critical issue that institutions are struggling to tackle proactively. The wellbeing of students is largely invisible to institutions unless specific mental health conditions are diagnosed and disclosed. In comparison to the importance placed on academic aspects, the affective experiences of education throughout the study journeys of students are rarely acknowledged. Approaches for students to develop emotional awareness, through which they learn to understand and manage their emotions, are limited. In this article, we describe the design and evaluation ofOur Journey, a platform for students to represent their study journeys through describing the events and emotions they experience. The conceptual and user experience design of the platform was derived from participatory activities with students and staff and has been further refined via several physical and online iterations. In this paper, we report findings from an exploratory pilot trial ofOur Journeywith 54 students studying for a range of qualifications at an online learning institution. Through an analysis of the journeys that the students produced and a post-trial survey, we found thatOur Journeycan support representations of emotional awareness in relation to study events which prompted students to reflect on important aspects of their study and personal development. The design and use of the platform have also prompted important considerations around how emotion is represented, as well as how the privacy and ownership of these representations of personal experiences can be managed to support students and institutions to potentially benefit from novel tools such asOur Journey.
Culture and Sexual Medicine: A Road Map for Clinical Inquiry and Practice
Authors: Bober Sharon L. , Chevalier Lydia L.
Published: June 2021

As the field of sexual medicine continues to grow, there has been increasing attention to the importance of the sociocultural components of the biopsychosocial model. Although important in all medical practice, culture and sexual health are particularly entwined, so engaging with sociocultural aspects of the patient experience as part of evaluation and treatment is necessary to optimize patient outcomes in this field. We invite clinicians to consider the importance of sexual health literacy, cultural humility, and support for patient volition as key aspects of moving care towards a model that embraces all aspects of the biopsychosocial model. The aim of the current paper is to provide readers with concrete steps and illustrative examples to help guide this process.
Thomas Aquinas on the Metaphysics of the Human Act
Authors: Löwe Can Laurens
Published: June 2021

This book offers a novel account of Aquinas's theory of the human act. It argues that Aquinas takes a human act to be a composite of two power-exercises, where one relates to the other as form to matter. The formal component is an act of the will, and the material component is a power-exercise caused by the will, which Aquinas refers to as the 'commanded act.' The book also argues that Aquinas conceptualizes the act of free choice as a hylomorphic composite: it is, materially, an act of the will, but it inherits a form from reason. As the book aims to show, the core idea of Aquinas's hylomorphic action theory is that the exercise of one power can structure the exercise of another power, and this provides a helpful way to think of the presence of cognition in conation and of intention in bodily movement.
Construction of Socio-Legal Dignity for Old Persons: Narrative Perspectives from Taiwan
Authors: Shee Amy Huey-Ling
Published: June 2021

Contemporary laws have been responding to the challenges of ageing societies. Elder people have gradually become a special, if not disadvantaged, social group to be protected, cared for, and even censored by law in the name of protection. The UN has long discussed a Convention to protect the distinctive human rights of old persons while invoking the Convention on the Rights of Persons with Disabilities to protect the dignity of senior citizens. Under national laws, adult-guardianship, welfare, and medical laws are strengthened in the name of better elder care, yet forcing old people to give up the freedom and autonomy that they have enjoyed throughout adulthood. This paper thus argues for the socio-legal construction of “elderhood” to respond to the special needs of senior citizens to maintain individual dignity. By observing narrative accounts of elders in care, socio-legal images of Taiwan elderhood may be presented for analyses. A proposal is then made to suggest the socio-legal construction of the individual dignity of elder people.
COVID-19 Vaccination: crucial roles and opportunities for the mental health professionals
Authors: Banerjee Debanjan , Mukhopadhyay Sanchari , Sahana Asmeen Mariam , Javed Afzal
Published: June 2021

Besides addressing the increased prevalence of psychiatric disorders, social challenges, and building community resilience during the crisis, mental health professionals (MHPs) are in a unique position to assist the vaccination drive against coronavirus disease-2019 (COVID-19) in various nations. Vaccination programs are adversely affected by misinformation, fake news and vaccine hesitancy fuelled by social media. MHPs can enable this vital public health strategy by prioritizing vaccination for individuals with severe mental illness (SMI) and substance use disorders, promote awareness and public education, debunk misinformation and integrate psychosocial care into the vaccination drives. In order to target the health inequity and discrimination faced by people with SMI coupled with their additional risks, the authors urge the global mental health fraternity to tailor these crucial roles with respect to COVID-19 vaccination based on the regional needs and contexts.
Satellite-derived dry-snow line as an indicator of the local climate on the Antarctic Peninsula
Authors: Zhou Chunxia , Liu Yong , Zheng Lei
Published: June 2021

Recent regional cooling has impacted the natural systems of the Antarctic Peninsula (AP); however, little is known concerning the changes in the high parts of the glacial systems. Dry-snow line (DSL), situated in the high parts of glaciers, is the uppermost limit of frequent or occasional surface melt. We analyse dry-snow line altitude (DSLA) changes on the AP during 2004–2020 using C-band synthetic aperture radar time series data. We demonstrate that the DSLA in the eastern part of the AP is usually higher than that of the western part. Moreover, using simulated climatic variables from regional climate models, the lowering in altitude of DSL of glaciers in most areas is identified as a response to a decrease in snowmelt and an increase in precipitation. Furthermore, correlation analyses between simulated climatic variables and the DSLA are conducted. These results present the sensitive response of variations in DSLA to meteorological conditions, and the capability of DSLA being a proxy of polar local climate in high-altitude areas with no in situ meteorological observations.
Split Feelings: Understanding Implicit and Explicit Political Persuasion
Authors: RYAN TIMOTHY J. , KRUPNIKOV YANNA
Published: June 2021

Research in psychology has established that people have visceral positive and negative reactions to all kinds of stimuli—so-called implicit attitudes. Implicit attitudes are empirically distinct from explicit attitudes, and they appear to have separate consequences for political behavior. However, little is known about whether they change in response to different factors than explicit attitudes. Identifying distinct antecedents for implicit and explicit attitudes would have far-reaching implications for the study of political persuasion. We hypothesized that implicit attitudes would change primarily in response to political advertisements’ emotional valence, but this turned out to be wrong. In contrast, our next hypothesis that implicit (but not explicit) attitudes would improve in response to increased familiarity with an attitude object was supported across several tests. Aside from this finding, our studies illustrate how routine preregistration helps researchers convey what they learned from each test—including when predictions are not borne out.
Metabolic and molecular signatures of improved growth in Atlantic salmon (Salmo salar) fed surplus levels of methionine, folic acid, vitamin B6and B12throughout smoltification

Published: June 2021

A moderate surplus of the one carbon (1C) nutrients methionine, folic acid, vitamin B6and B12above dietary recommendations for Atlantic salmon has shown to improve growth and reduce hepatosomatic index in the on-growing saltwater period when fed throughout smoltification. Metabolic properties and molecular mechanisms determining the improved growth are unexplored. Here, we investigate metabolic and transcriptional signatures in skeletal muscle taken before and after smoltification to acquire deeper insight into pathways and possible nutrient–gene interactions. A control feed (Ctrl) or 1C nutrient surplus feed (1C+) were fed to Atlantic salmon 6 weeks prior to smoltification until 3 months after saltwater transfer. Both metabolic and gene expression signatures revealed significant 1C nutrient-dependent changes already at pre-smolt, but differences intensified when analysing post-smolt muscle. Transcriptional differences revealed lower expression of genes related to translation, growth and amino acid metabolisation in post-smolt muscle when fed additional 1C nutrients. The 1C+ group showed less free amino acid and putrescine levels, and higher methionine and glutathione amounts in muscle. For Ctrl muscle, the overall metabolic profile suggests a lower amino acid utilisation for protein synthesis, and increased methionine metabolisation in polyamine and redox homoeostasis, whereas transcription changes are indicative of compensatory growth regulation at local tissue level. These findings point to fine-tuned nutrient–gene interactions fundamental for improved growth capacity through better amino acid utilisation for protein accretion when salmon was fed additional 1C nutrients throughout smoltification. It also highlights potential nutritional programming strategies on improved post-smolt growth through 1C+ supplementation before and throughout smoltification.
Representation and Ministerial Influence on Cabinet Committees in Canada
Authors: Ie Kenny William
Published: June 2021

Cabinet committees are important sites of executive politics in Canada. This article examines the extent to which two representational attributes—gender and region—determine influence, as a function of cabinet committee structure. Employing a dataset of ministers under the three most recent prime ministers, I find that female ministers are less likely than male ministers to be influential in terms of connections to other ministers, to belong to the core of most influential ministers and to be represented on the most powerful committees or chairing committees. However, there is evidence of improvement over time. While regional representation is an imperative in cabinet making for Canadian prime ministers, its role in determining ministerial influence within committees is not evident: ministers from less-represented regions are no more likely to be influential than other ministers. This analysis highlights a neglected but central arena for social representation in Canadian government.
Longitudinal association between cardiovascular risk factors and depression in young people: a systematic review and meta-analysis of cohort studies
Authors: Chaplin Anna B. , Daniels Natasha F. , Ples Diana , Anderson Rebecca Z. , Gregory-Jones Amy , Jones Peter B. , Khandaker Golam M.
Published: June 2021

Background

Depression is a common and serious mental illness that begins early in life. An association between cardiovascular disease (CVD) and subsequent depression is clear in adults. We examined associations between individual CVD risk factors and depression in young people.

Methods

We searched MEDLINE, EMBASE, and PsycINFO databases from inception to 1 January 2020. We extracted data from cohort studies assessing the longitudinal association between CVD risk factors [body mass index (BMI), smoking, systolic blood pressure (SBP), total cholesterol, high-density lipoprotein] and depression, measured using a validated tool in individuals with mean age of 24 years or younger. Random effect meta-analysis was used to combine effect estimates from individual studies, including odds ratio (OR) for depression and standardised mean difference for depressive symptoms.

Results

Based on meta-analysis of seven studies, comprising 15 753 participants, high BMI was associated with subsequent depression [pooled OR 1.61; 95% confidence interval (CI) 1.21–2.14; I2 = 31%]. Based on meta-analysis of eight studies, comprising 30 539 participants, smoking was associated with subsequent depression (pooled OR 1.73; 95% CI 1.36–2.20; I2 = 74%). Low, but not high, SBP was associated with an increased risk of depression (pooled OR 3.32; 95% CI 1.68–6.55; I2 = 0%), although this was based on a small pooled high-risk sample of 893 participants. Generalisability may be limited as most studies were based in North America or Europe.

Conclusions

Targeting childhood/adolescent smoking and obesity may be important for the prevention of both CVD and depression across the lifespan. Further research on other CVD risk factors including blood pressure and cholesterol in young people is required.
Research into practice: Virtual exchange in language teaching and learning
Authors: Dooly Melinda , Vinagre Margarita
Published: June 2021

In this article, the authors reflect on the ways research on Virtual Exchange (VE) has had an impact on language education practices and, conversely, areas in which research has been underexplored, misapplied or perhaps even over applied by VE practitioners in formal education settings. Starting from a brief historical overview of VE, the text first outlines the features widely accepted as key aspects of this pedagogical approach before considering to what extent research results can be identified in VE implementation. Principal topics covered are the main aims regarding language development when VE is applied, assessment of language development through VE and VE and intercultural competence. While the article is not intended as a comprehensive review, it provides insight into the main foci of VE research and how these findings are reaching the language classroom (primary, secondary and university).
Acquisition of variability in Akan Phonology: Labio-palatalized consonants and front rounded vowels
Authors: AMOAKO Wendy Kwakye , STEMBERGER Joseph Paul
Published: June 2021

This paper addresses how input variability in the adult phonological system is mastered in the output of young children in Akan, a Kwa language spoken in Ghana, involving variability between labio-palatalized consonants and front rounded vowels. The high-frequency variant involves a complex consonant which is expected to be mastered late, while the low-frequency variant involves a front rounded vowel which is expected to be mastered relatively early. Late mastery of complex consonants was confirmed. The high-frequency labiopalatalized-consonant variant was absent at age 3 and not yet mastered even at age 5. All children produced the easier-to-produce low-frequency front-rounded-vowel variant, most at far greater frequency than in adult speech, implying that a child's output limitations can affect which variant the child targets for production. Modular theories, in which phonological plans reflect only the characteristics of adult input, fail to account for our results. Non-modular theories are implicated.
‘Ein sonderbar’ Ding’: Music, the Historical and the Problem of Temporal Representation in Der Rosenkavalier
Authors: Taylor Benedict
Published: June 2021

Der Rosenkavalier is an opera that foregrounds time: the problem of time, as transience, passing and ultimately death for the aging Marschallin, and a potentially more redemptive quality, the category of the Augenblick associated with the young lovers Octavian and Sophie, in which the temporal intersects with the eternal. It is also a work that has traditionally marked the turning point in Strauss's relation to historical time and the idea of musical progress, as the composer supposedly retreated from the modernity of Salome and Elektra to a more conservative idiom. The temporal qualities manifested in Der Rosenkavalier invite comparison with another work from this period that similarly foregrounds the concept of time, Thomas Mann's Der Zauberberg. In this self-styled ‘novel of time’, Mann raises a number of problems concerning the human limitations on perceiving time and its artistic representation, especially with regard to music. Disputing the contention of the narrator of Mann's novel that music cannot ‘narrate time’, I show that Strauss's music in fact exemplifies music's capacity to express ‘the historical in time’, using Der Rosenkavalier as a case study for addressing the philosophical problem of temporal representation in art. I argue that Der Rosenkavalier – both Hofmannsthal's text and Strauss's music – is in several significant ways ‘an opera about time’ – the temporal and the eternal, the historical and what I call the ‘metahistorical’.
Conceptual representations in bicultural bilinguals: An ERP approach
Authors: Pan Xuan , Xiong Andy , Jouravlev Olessia , Jared Debra
Published: June 2021

We investigated conceptual representations for translation word pairs in bilinguals who learned their languages in different cultural contexts. Mandarin–English bilinguals were presented with a word, and then a picture, and decided if they matched. Both behavioural and ERP data were collected. In one session, words were in English and in another they were the Mandarin translations. Critical pictures matched the prior word and were either biased to Chinese or Canadian culture. There was an interaction of test language and picture type in RT and errors in the behavioural data, and in five components in the ERP data, indicating that the task was easier when the culture depicted in the picture was congruent with the language of the preceding word. These findings provide evidence that the specific perceptual experiences that bilinguals encounter when learning words in each language have an impact on the semantic features that are activated by those words.
Educational inequalities in obesity: a multilevel analysis of survey data from cities in Latin America
Authors: Mazariegos Mónica , Auchincloss Amy H , Braverman-Bronstein Ariela , Kroker-Lobos María F , Ramírez-Zea Manuel , Hessel Philipp , Miranda J Jaime , Pérez-Ferrer Carolina
Published: June 2021

Objective:

Using newly harmonised individual-level data on health and socio-economic environments in Latin American cities (from the Salud Urbana en América Latina (SALURBAL) study), we assessed the association between obesity and education levels and explored potential effect modification of this association by city-level socio-economic development.

Design:

This cross-sectional study used survey data collected between 2002 and 2017. Absolute and relative educational inequalities in obesity (BMI ≥ 30 kg/m2, derived from measured weight and height) were calculated first. Then, a two-level mixed-effects logistic regression was run to test for effect modification of the education–obesity association by city-level socio-economic development. All analyses were stratified by sex.

Setting:

One hundred seventy-six Latin American cities within eight countries (Brazil, Chile, Colombia, Costa Rica, El Salvador, Guatemala, Mexico and Peru).

Participants:

53 186 adults aged >18 years old.

Results:

Among women, 25 % were living with obesity and obesity was negatively associated with educational level (higher education–lower obesity) and this pattern was consistent across city-level socio-economic development. Among men, 18 % were living with obesity and there was a positive association between education and obesity (higher education–higher obesity) for men living in cities with lower levels of development, whereas for those living in cities with higher levels of development, the pattern was inverted and university education was protective of obesity.

Conclusions:

Among women, education was protective of obesity regardless, whereas among men, it was only protective in cities with higher levels of development. These divergent results suggest the need for sex- and city-specific interventions to reduce obesity prevalence and inequalities.

To assess the food environment at OsloMet, through the nutritional profile and processing level of available commercial foods and drinks, as well as to determine food-purchasing behaviours, preferences and opinions on the food environment, in order to identify whether interventions on campus need to be conducted.

Design:

Cross-sectional descriptive study.

Setting:

Pilestredet and Kjeller campus of OsloMet (Norway).

Participants:

To analyse the nutritional profile of products offered at all food outlets (seven canteens, three coffee shops and two vending machines) at the main campuses three criteria were applied: those proposed by the Spanish Agency for Food Safety and Nutrition, the UK nutrient profiling model and those of the Food and Drink Industry Professional Practices Committee Norway. In addition, products were classified by processing level, using the NOVA system. Food purchasing, food choice behaviours and opinions were analysed through a survey online, in which 129 subjects participated.

Results:

With regard to the first of the objectives, the combination of the above-mentioned criteria showed that 39·8 % of the products were ‘unhealthy’ and 85·9 % were ‘ultra-processed’. Regarding the second objective, the most important determinants of food choice were taste, convenience, and cost and nutrition/health value. The most common improvements suggested were lowering the cost, improving the allergen information on labelling and increasing the variety of fresh and healthy foods.

Conclusions:

A high proportion of the products offered were considered ‘unhealthy’ and highly processed. Interventions that improve food prices, availability and information on labelling would be well-received in this community.

The measurement of the composition of ε-Ga2O3 and the quantification of Sn doping in ε-Ga2O3:Sn by laser-assisted atom probe tomography (APT) may be inaccurate depending on the experimental conditions. Both the role of the laser energy and surface electric field were investigated, and the results clearly indicate that deviations from stoichiometry are observed changing the electric field conditions during APT. The measured atomic fraction of Ga can change from 0.45 at low field to 0.38 at high field, to be compared with the expected 0.4. This was interpreted in terms of preferential evaporation of Ga at high field and deficit of O at low field, which was caused by the formation of neutrals. The quantification of Sn-doping is accurate at low-field conditions, with an overestimation of the detected Sn-metallic fraction at high field. This suggests that Sn has a higher evaporation field compared to Ga. Finally, multiple detection events were in-depth studied, revealing that three dissociation reactions occur during APT: GaO2+ → Ga+ + O+; Ga2O22+ → Ga+ + GaO2+; Ga3O22+ → Ga+ + Ga2O2+. Nevertheless, only 2% of the detected events are related to such dissociation reactions, too small a fraction to fully explain the observed deviation from the stoichiometric composition in ε-Ga2O3.

Zusammenfassung. Suizidales Erleben und Verhalten ist in klinischen Kontexten sehr verbreitet. Während international diverse Messinstrumente zur Erfassung von Suizidalität entwickelt und validiert wurden, gibt es nur wenige deutsche Messinstrumente. In der vorliegenden Studie wurde die neu entwickelte Skala Suizidales Erleben und Verhalten (SSEV) in fünf Stichproben mit insgesamt N = 1 099 Proband_innen im Hinblick auf ihre psychometrischen Eigenschaften untersucht. Die faktorenanalytische Untersuchung (explorative und konfirmatorische Faktorenanalyse) ergab eine eindimensionale Struktur des Fragebogens. Die interne Konsistenz der SSEV ist hoch und es zeigten sich erwartungsgemäß positive Zusammenhänge zu diversen Maßen aktueller Theoriemodelle suizidalen Erlebens und Verhaltens, sowie zu Depressivität, Angst und Stress. Weitere Analysen zeigten erwartungskonform negative Zusammenhänge mit sozialer Unterstützung und positiver mentaler Gesundheit. Insgesamt verweisen die Ergebnisse darauf, dass es sich beim SSEV um ein reliables und valides Instrument zur Erfassung von akutem suizidalem Erleben und Verhalten handelt, welches in der Forschung und der klinischen Praxis angewendet werden kann.

Zusammenfassung. Situierte Formate der Hochschullehre stellen authentische Kontexte bereit, in denen Studierende praktische Erfahrung sammeln, Handlungsoptionen abwägen, komplexe Problemkonstellationen wissenschaftlich analysieren und Aspekte der späteren beruflichen Tätigkeit kennenlernen können. Bislang fehlen geeignete Lehrevaluationsinstrumente für solche Lehrformate. Die vorliegende Arbeit beschreibt die Entwicklung und Validierung sechs ökonomisch einsetzbarer Skalen für die Einschätzung von Handlungswissen, Reflexion und Berufsbezug in der Hochschullehre. Drei Skalen erfassen dabei die Selbsteinschätzung von studentischen Kompetenzen. Drei weitere, parallel entwickelte Skalen erfassen wahrgenommene Merkmale des Lernangebots. Die Skalen wurden theoriebasiert entwickelt und auf Basis empirischer Datenerhebungen überarbeitet sowie inhaltlich, faktoriell und kriterial validiert. Die internen Konsistenzen sind gut. Die postulierte Modellstruktur wird durch eine konfirmatorische Faktorenanalyse bestätigt. Die Kriteriumsvalidität wird mittels verschiedener personenbezogener Merkmale und durch konstruktnahe Skalen überprüft.

Following the end of the Van Allen Probes mission, the Arase satellite offers a unique opportunity to continue in‐situ radiation belt and ring current particle measurements into the next solar cycle. In this study we compare spin‐averaged flux measurements from the MEPe, HEP‐L, HEP‐H, and XEP‐SSD instruments on Arase with those from the MagEIS and REPT instruments on the Van Allen Probes, calculating Pearson correlation coefficient and the mean ratio of fluxes at L* conjunctions between the spacecraft. Arase and Van Allen Probes measurements show a close agreement over a wide range of energies, observing a similar general evolution of electron flux, as well as average, peak, and minimum values. Measurements from the two missions agree especially well in the 3.6 = L* ≤ 4.4 range where Arase samples similar magnetic latitudes to Van Allen Probes. Arase tends to record higher flux for energies <670 keV with longer decay times after flux enhancements, particularly for L* < 3.6. Conversely, for energies >1.4 MeV, Arase flux measurements are generally lower than those of Van Allen Probes, especially for L* > 4.4. The correlation coefficient values show that the >1.4 MeV flux from both missions are well correlated, indicating a similar general evolution, although flux magnitudes differ. We perform a preliminary intercalibration between the two missions using the mean ratio of the fluxes as an energy‐ and L*‐ dependent intercalibration factor. The intercalibration factor improves agreement between the fluxes in the 0.58–1 MeV range.
The Impact of Grain Size on the Hydromechanical Behavior of Mudstones
Authors: Reece Julia S.
Published: June 2021

The consolidation behavior of mudstone is controlled by the clay fraction and affects a wide range of deformation and fluid transport processes in accretionary wedge systems. I analyze the compression and permeability behavior of six sediment mixtures based on uniaxial resedimentation and constant rate of strain consolidation data. The sediment mixtures are composed of varying proportions of hemipelagic mudstone and silt‐size silica resulting in clay fractions ranging from 56% to 32% by mass. The hemipelagic mudstone is from Site C0011 drilled seaward of the Nankai Trough, offshore Japan, during Integrated Ocean Drilling Program Expedition 322. I show that porosity and compression index consistently decrease and permeability consistently increases with decreasing clay fraction over vertical effective stresses ranging from 0 to 21 MPa. Backscattered electron microscope images reveal that matrix porosity declines and large, jagged pore throats are being preserved in compaction shadows between silt grains as the clay fraction decreases. I compare the behavior of reconstituted samples with that of intact core and field measurements and interpret that increasing creep with depth and different mudstone fabrics explain differences in their compression curves. Finally, I provide empirical compression and permeability models that describe the evolution of porosity (void ratio) and permeability with vertical effective stress and as a function of grain size. Characterizing the in situ hydromechanical properties of subduction inputs is critical in order to relate input sediments to those at frontal thrust regions and predict pore fluid pressures and compaction‐driven fluid sources within the outer part of the accretionary prism.
