Abstract
Purpose
Occupational exposure limits (OEL) for nitrogen oxides (NO, NO2) and diesel exhaust (EC-DPM) were reassessed by the German authorities in 2016/2017. We performed a clinical cross-sectional study among salt and potash underground workers exposed to these substances at relatively high levels to examine possible indicators of acute effects on workers’ health.

Methods
We measured post- versus pre-shift differences in cardiovascular, inflammatory, immune, and respiratory effect biomarkers and assessed their associations with personal exposures measured during the same shift. We also compared post- versus pre-shift differences in biomarker levels between exposure groups defined based on work site and job type.

Results
None of the above-ground workers exceeded the OEL for NO2 and only 5% exceeded the OEL for EC-DPM exposure. Among underground workers, 33% of miners and 7% underground maintenance workers exceeded the OEL for NO2; the OEL for EC-DPM was exceeded by 56% of miners and 17% of maintenance workers.
Some effect biomarkers (thrombocytes, neutrophils, MPO, TNF-α, IgE, FeNO) showed statistically significant differences between pre- versus post-shift measurements; however, there were no consistent associations between pre- and post-shift differences and exposure group or personal exposure measurements during the shift.

Conclusions
We did not find evidence of associations between workplace exposure to NO, NO2 or EC-DPM and clinically relevant indicators of acute cardiovascular, inflammatory and immune, or respiratory effects among salt and potash underground workers in Germany.
The Path from Arc Welding to Additive Manufacturing of Multi-material Parts Using Directed Energy Deposition
Authors: Adams Tom-Eric , Mayr Peter 
Published: May 2022

AbstractWithin this contribution, the transfer of knowledge from conventional fusion and deposition welding using electric arc processes to advanced directed energy deposition (DED) of multi-material structures in additive manufacturing are presented. Gas metal arc and plasma welding have been used for decades to produce either joints or metallic deposits with desired properties. Also creating certain shapes by depositing weld metal in a layer-wise manner has been known for approximately 100 years. With the rise of additive manufacturing, conventional arc welding processes have been extensively used to “print” 3‑dimensional parts. The possibility of additively manufacturing multi-material parts or transition parts is of particular interest as this has the potential to create load-efficient structures or even create new alloys within the AM process. Within this contribution, Wire Arc Additive Manufacturing (WAAM) and 3D Plasma Metal Deposition (3DPMD) for the manufacturing of multi-material and transition parts are discussed. The experience with various alloys from carbon steels, high-alloyed steels, and titanium- and nickel-based alloys are presented.
Diagnosing PrEP Communication Self-Efficacy in a Community-Based Peer Leader Intervention for Black Sexual Minority Men
Authors: Young Lindsay E. , Baird Ashley , Schneider John A. 
Published: May 2022

AbstractHIV prevention interventions that leverage endogenous peer leaders to communicate about Pre-Exposure Prophylaxis (PrEP) and other HIV prevention tools in their social networks offer a way to reach greater portions of communities most impacted by HIV like Black/African American gay, bisexual, same gender-loving, and other sexual minority men (BSMM). However, the success of these interventions hinge on the communication self-efficacy of its peer leaders. In this exploratory study, we present a multi-theoretical framework that situates the PrEP communication self-efficacy (PCSE) of a cohort of young BSMM peer leaders (n = 303) in the context of personal, behavioral, social, and structural factors. Using censored regression models, our analysis shows that PCSE is influenced by evaluations of PrEP itself (its relative advantage, complexity, and compatibility), network embeddedness (degree centrality) among other BSMM, social media network exposure to HIV information, and medical mistrust. We conclude with a discussion of the practical implications of our findings for intervention design and implementation.
Lath martensite substructure evolution in low-carbon microalloyed steels

Published: May 2022

Abstract
Lath martensite substructures in as-quenched plain carbon steels exhibit dislocation-like contrast in the transmission electron microscope. More recent observations reported internal twins and nanoscale auto-tempered intra-lath carbides as additional lath substructures in ultra-low-C binary Fe–C steels. Modern microalloyed steels often have similar ultra-low C contents besides microalloying elements like Ti, Nb or V and, more recently, Mo, to achieve high strength, toughness and weldability. Nonetheless, little is known about the lath substructure evolution in the as-quenched state of microalloyed steels. This study investigates the hierarchical martensite substructure evolution post-quenching of microalloyed Nb and NbMo steels with 0.1 wt% C. Hierarchical microstructure characterization was done using scanning and transmission electron microscopy, and electron backscatter diffraction methods including parent grain reconstructions with MTEX. Thermokinetic simulations using MatCalc to determine the carbide evolution during auto-tempering were corroborated with site-specific transmission electron microscopy. Mo addition led to lowering of the martensite start temperature, yet the Nb steel showed a finer hierarchical microstructure. Finer laths with in-lath dislocations, short and long twins, and lath boundary decoration of carbides were found in the Nb steel. Conversely, laths in the NbMo were wider, with frequent intra-lath auto-tempered precipitates in the vicinity of dislocations, without twins.

Published: May 2022

AbstractHollow capsules with multi-shelled or multicomponent structures are essential materials for various applications. Biomedical applications like disease diagnosis, therapy, and monitoring have special significance as they aim to improve health conditions. This review demonstrated a comprehensive overview of hollow, multifunctional structures incorporating meaningful use of nanotechnology and its’ unique prospects in medicine such as patient-specific treatment, multimodal imaging, multimodal therapy, simultaneous delivery of drugs and imaging probes, and actively targeted delivery. The internal hollow cavity provides safe and controlled drug release while also enabling transport of functional moieties to target sites. This review explored the performance of different organic, inorganic, and metallic multicomponent capsules that have been reported for biomedical applications, mainly diagnostic imaging and drug delivery. Material compositions, morphologies, and synthesis strategies involved in fabricating such multifunctional systems have been discussed in detail. It is expected that with time, more sophisticated and precise systems will come to light as the outcome of ongoing concentrated research efforts.
The Effect of Joint Production on the Accuracy and Complexity of Second Language Writing
Authors: Sang Zilin , Zou Weicheng 
Published: May 2022

AbstractAlthough written corrective feedback and collaborative writing have been extensively researched in second language writing, there have been few ecologically valid classroom-based studies. To bridge the gap, the current study proposed joint production as a pedagogy to integrate teacher-scaffolded feedback and collaborative dialogue and aimed to examine its effect on the development of second language writing. A quasi-experimental study was undertaken on two intact groups of EFL learners over an academic semester of 18 weeks. Results showed that the experimental group (N = 30) outperformed the control group (N = 29) significantly in accuracy, confirming the effectiveness of joint production in promoting accuracy in L2 writing. Developmentally, accuracy was steadily developed over time and was negatively correlated with complexity. Possible explanations and implications of the findings are also discussed.
Faultless disagreement without contradiction: expressive-relativism and predicates of personal taste
Authors: Berškytė Justina , Stevens Graham 
Published: May 2022

AbstractIn this paper we motivate and develop a new approach to predicates of personal taste within the framework of semantic relativism. Our primary goal is to explain faultless disagreement—the phenomenon where two parties disagree, yet both have uttered something true—which is often thought to arise from the use of predicates of personal taste. We combine semantic relativism with an expressivist semantics to yield a novel hybrid theory which we call Expressive-Relativism. We motivate the theory by rehearsing a famous objection to Relativism from Frege which we interpret as severing the connection between contradiction and disagreement for relativists. Endorsing the objection, we respond by enriching relativism with an expressivist component which explains disagreement over matters of taste as a refusal to share perspectives rather than as resting on contradiction.
The Global Report on Adult Learning and Education (GRALE): Strengths, weaknesses and future directions
Authors: Boeren Ellen , Rubenson Kjell 
Published: May 2022

AbstractOne of the core outcomes of the Sixth International Conference on Adult Education (CONFINTEA VI) held in 2009 was the Belém Framework for Action (BFA). Its signatories committed to monitoring the most recent development stages of adult learning and education (ALE) worldwide on a regular basis, and to present and assess results in a global report. Coordinated by the UNESCO Institute for Lifelong Learning, surveys have been conducted and documented in four GRALE reports over the past decade. A fifth report is currently being prepared for CONFINTEA VII, to be held in June 2022. This article critically analyses the project of compiling a Global Report on Adult Learning and Education (GRALE) at roughly three-year intervals. Drawing on an evaluative framework for research quality developed by Pär Mårtensson and colleagues, the authors of this article investigate to what extent the GRALE approach to monitoring and reporting on ALE so far has been (1) credible (e.g. based on rigorous research methodologies and methods); (2) contributory (e.g. relevant and applicable to practice, generalisable); (3) communicable (e.g. accessible, understandable and readable in terms of report structure); and (4) conforming (e.g. with ethical standards). The purpose of this evaluation is for it to serve as a contribution to enhancing the quality of monitoring approaches in the field of ALE. This is vital for working towards future directions of ALE which are shaped by a high-quality evidence base. Ultimately, this will not only make ALE more accessible, fair, diverse and effective, but will also add to insights on how to achieve the Sustainable Development Goals in a similar way, especially since ALE indirectly but fundamentally affects the success of all 17 goals.

Published: May 2022

AbstractA sunspot catalog was published by the Madrid Astronomical Observatory from sunspot observations made by Rafael Carrasco and his assistants for the period November 1931 – December 1933. We have digitized this catalog and carried out a quality control to detect inconsistencies. We present a machine-readable version of this sunspot catalog together with an erratum list. Moreover, we compared the Madrid sunspot number and area with other reference series. We found that sunspots in the northern hemisphere were predominant during this period, confirming previous studies. We have also analyzed the group morphological typologies registered in the catalog and show a butterfly diagram drawn with this new information. A comparison with the sunspot catalog by the Royal Greenwich Observatory shows that almost all the groups included in the Carrasco’s catalog are also present in the aforementioned catalog.

AbstractAn abundance of literature has examined barriers to women’s equitable representation in science, technology, engineering, and math (STEM) fields, with many studies demonstrating that STEM fields are not perceived to afford communal goals, a key component of women’s interest in future careers. Using Goal Congruity Theory as a framework, we tested the longitudinal impact of perceptions of STEM career goal affordances, personal communal and agentic goal endorsements, and their congruity on persistence in science from the second through fourth years of college among women in STEM majors in the United States. We found that women’s intent to persist in science were highest in the fall of their second year, that persistence intentions exhibited a sharp decline, and eventually leveled off by their fourth year of college. This pattern was moderated by perceptions of agentic affordances in STEM, such that women who believe that STEM careers afford the opportunity for achievement and individualism experienced smaller declines. We found that higher perceptions of communal goal affordances in STEM consistently predicted higher persistence intentions indicating women may benefit from perceptions that STEM affords communal goals. Finally, we found women with higher agentic affordances in STEM also had greater intentions to persist, and this relationship was stronger for women with higher agentic goals. We conclude that because STEM fields are stereotyped as affording agentic goals, women who identify interest in a STEM major during their first years of college may be drawn to these fields for this reason and may benefit from perceptions that STEM affords agentic goals.
An automated system recommending background music to listen to while working
Authors: Yakura Hiromu , Nakano Tomoyasu , Goto Masataka 
Published: May 2022

AbstractMany people listen to music while working nowadays. However, conventional recommendation systems that are designed for playing songs matching user preferences cannot be applied for such a situation. This is because previous research showed that listeners’ concentration can be negatively affected not only by music that listeners strongly dislike but also by music that the listeners strongly like. Therefore, when we consider a recommendation system to be used while working, it is desirable to avoid both songs the user likes very much and songs the user dislikes very much. Given this background, we propose FocusMusicRecommender, a system designed specifically for recommending music to listen to while working. It summarizes songs automatically and plays them successively in order to enable users to give not only “dislike (very much)” feedback via a “skip” button but also “like (very much)” feedback via a “keep listening” button. The feedback is then combined with the users’ concentration level that is estimated from their behavioral history during the playback of the corresponding song, which allows the system to obtain preference information that distinguishes between “like” and “like very much” without burdening the user who is working. Based on the preference information, the system estimates the preference levels of unplayed songs and prioritizes the songs for subsequent playback by also considering the user’s current concentration level. Our experiments showed the validity and effectiveness of the proposed method, including the accuracy of the concentration level estimation. Moreover, our user study verified the suitability of the recommendation results from both the observed behavior and obtained comments of the participants.

Published: May 2022

AbstractDue to their simplicity in preparation, sensitivity and selectivity, fluorescent probes have become the analytical tool of choice in a wide range of research and industrial fields, facilitating the rapid detection of chemical substances of interest as well as the study of important physiological and pathological processes at the cellular level. In addition, many long-wavelength fluorescent probes developed have also proven applicable for in vivo biomedical applications including fluorescence-guided disease diagnosis and theranostics (e.g., fluorogenic prodrugs). Impressive progresses have been made in the development of sensing agents and materials for the detection of ions, organic small molecules, and biomacromolecules including enzymes, DNAs/RNAs, lipids, and carbohydrates that play crucial roles in biological and disease-relevant events. Here, we highlight examples of fluorescent probes and functional materials for biological applications selected from the special issues “Fluorescent Probes” and “Molecular Sensors and Logic Gates” recently published in this journal, offering insights into the future development of powerful fluorescence-based chemical tools for basic biological studies and clinical translation.
The Binding Problem for Strong Experiential Monism
Authors: Heikkinen Santtu 
Published: May 2022

AbstractIn this article, I explicate a new problem for a variant of panpsychism, strong experiential monism, that is the view that all being is experiential. I contrast the view with weak experiential monism, a softer variant that allows for non-experiential bare particulars to act as the carriers of properties. I argue that strong experiential monism can’t explain what works as the ontological commonality between the referents of one experience of something and another experience of that same thing; in other words, in virtue of what are those experiences about the same thing at all. If they aren’t about the same ontological existent at all, the apparent mutual coherence between these experiences (as manifest in our ability to discuss about them in a seemingly coherent way, for example) requires explanation. I argue that strong experiential monism necessitates a more or less brute kind of parallelism between the experiences to explain their mutual coherence. Alternatively, the strong experiential monist must either retreat to weak experiential monism and non-experiential bare particulars or to a more robust kind of property dualism or dual-aspect monism.
Sediment dynamics at different timescales on an embayed coast in southeastern Australia

Published: May 2022

AbstractThe concept of coastal sediment compartments has recently been adopted at a national scale in Australia to better understand sediment and shoreline dynamics and to underpin management of future shoreline behaviour in response to impacts of climate change. Geomorphological studies in southern NSW have provided a foundation for development of conceptual models of estuary and sandy barrier evolution. Geochronological reconstructions using radiocarbon, optically-stimulated luminescence, and other dating techniques, reviewed in this paper, demonstrate that adjacent compartments are at successive stages. Three compartments, Illawarra, Shoalhaven and Moruya, are compared, each with different catchment characteristics and different levels of human intervention. Landform change and sediment accumulation at millennial timescales enable estimates of past sediment accretion (vertical accumulation) and horizontal displacement of shorelines (particularly progradation), as a first step towards quantifying volumetric changes of morphology. Lake Illawarra is a barrier estuary at an early stage of infill, but land-use change, urbanisation, and engineering structures at the entrance have accelerated rates of sediment accumulation. The Shoalhaven River has infilled its estuary and delivers sand to the coast. It has been subject to several conspicuous anthropogenic interventions. At Moruya, ongoing supply of sand, primarily from offshore rather than from the catchment, has resulted in beach-ridge plains (strandplains) with changes in their alongshore inter-connectivity driven by differential embayment infilling. Millennial-scale geomorphology indicates landform change providing a means to determine natural trajectories of sediment transfer. However, variability is apparent at century and decadal timescales, compounded by various anthropogenic interventions. Disentangling natural and anthropogenic influences will be necessary to provide greater confidence in estimating past and present sediment budgets. Assessing sand sources and transport rates is important in relation to engineering interventions at entrances, and long-term resilience of coastal habitats. Such issues are the focus of coastal management programs, and this synthesis emphasises the relevance of a sediment budget approach to understand contemporary sediment pathways and provide an indication of future response to engineering interventions and sensitivity to climate change.
Neurofeedback training: Decreases in Mu rhythm lead to improved motor performance in complex visuomotor skills

Published: May 2022

Abstract
The physiological function of the Mu rhythm (8–13 Hz in the central region) is still unclear, particularly its role in visuomotor performance in sports (shooting vs. golf putting), as both the complexity of the motor skills (i.e., simple vs. complex visuomotor skills) and the skill level (e.g., novices vs. experts or low-skilled vs. highly skilled) may modulate Mu rhythm. To gain a broader understanding of the association between Mu rhythm and visuomotor skill performance, a study design that considers both a control moderator (the difference in skill level) and the ability to manipulate Mu rhythm (i.e., either increase or decrease Mu rhythm) is required. To achieve this, we recruited 30 novice golfers who were randomly assigned to either the increased Mu rhythm group (IMG), decreased Mu rhythm group (DMG), or sham group (SG) and used electroencephalographic-neurofeedback training (EEG-NFT) to manipulate Mu rhythm during a golf putting task (complex visuomotor skill). The aim was to determine whether the complexity of the motor skill was a potential moderator of Mu rhythm. We mainly found that Mu power was significantly decreased in the DMG following EEG-NFT, which lead to increased motor control and improved performance. We suggest that (1) the complexity of the motor skill, rather than the difference in skill level, may be a potential moderator of Mu rhythm and visuomotor performance, as our results were not consistent with a previous study that reported that increased Mu rhythm improved shooting performance (a simple visuomotor task) in novices.
