AbstractLaboratory e‐learning support tools can assist students' learning while preparing for laboratory classes. To successfully work in such virtual experimental environments (VEEs) outside class, students require self‐regulated learning (SRL) skills. A deeper understanding of the continuous reciprocal interactions between SRL, satisfaction, and online engagement is needed to develop more effective online learning experiences. This study therefore aimed to explore the interconnection between students' satisfaction with, effort/importance and engagement in an exemplary VEE, and to relate this to their perceived SRL and learning outcomes. Based on surveys in 79 university students, SRL was related to VEE engagement, effort/importance, and satisfaction. VEE engagement and satisfaction were not related to learning outcomes, while SRL and effort were. Students with different SRL also tended to interact differently with the VEE and experienced differing degrees of procedural and feedback support by the e‐environment. We conclude that, for optimal learning experience and outcomes, students' effort regulation and SRL need to be supported while interacting with the VEE, preferably by interventions that integrate personalized and adaptive features. This study has implications for designing and optimizing VEEs and indicates that future research should focus on VEEs taking students' SRL and effort regulation into account to support individual learners effectively.

Published: January 2024

AbstractBackgroundInhibitory control ability is a crucial cognitive function that enables individuals to regulate their impulses and behaviors in a goal‐directed manner. However, with the increasing prevalence of internet gaming disorder (IGD), there has been growing concern about the impact of excessive gaming on inhibitory control ability. Despite the accumulating evidence on this topic, the research conclusion on whether people with IGD have worse inhibition control ability than healthy controls remains inconsistent, and the lack of effective electroencephalography prediction indicators further complicates this issue. To address this research gap, the present study aimed to investigate whether N2 event‐related potential (ERP) and P3 ERP components could serve as reliable indicators of inhibitory control ability in individuals with IGD.MethodsTo achieve this goal, a systematic literature search was conducted in several databases, including Web of Science, ScienceDirect (EBSCO), SpringerLink, PubMed, and Wiley Online Library. The inclusion criteria were strictly implemented to ensure the quality of the studies included in the meta‐analysis. In the end, a total of 5 studies, with 139 participants diagnosed with IGD and 139 healthy controls, were included in the analysis.ResultsMeta‐analysis revealed large effect sizes of N2 and P3 amplitudes in individuals with IGD, indicating that these two ERP components could be potential indicators of inhibitory control ability. Specifically, the N2 and P3 amplitude was significantly larger in individuals with IGD than in the healthy control group, suggesting deficits in inhibitory control function and increased impulsivity in the IGD group. In the inhibition control task, the IGD group required more cognitive resources to suppress impulsive responses.ConclusionOverall, the findings of this meta‐analysis shed light on the potential use of N2 and P3 amplitudes as reliable indicators of inhibitory control ability in individuals with IGD. The results provide crucial insights into the neural mechanisms underlying inhibitory control impairment in IGD, which could inform the development of effective interventions for this condition. Further research is needed to explore the functional significance of these ERP components and their potential clinical applications in the diagnosis and treatment of IGD.
What do you Think about Parenting? Challenges to Cohesiveness in Child Protection Teams
Authors: Pereira Dora 
Published: January 2024

AbstractChild protection work requires professionals to manage the different perspectives regarding intervention aims and strategies associated with different personal, academic and organisational backgrounds. Parenting assessment is a determinant task for intervention and for children's future where universal or automatic criteria remain unavailable. This study aimed to explore and characterise the existing agreement (and disagreement) between child protection workers on statements related to judgements on parenting. A total of 325 Portuguese social workers participated in the study, mostly with a background in social work and psychology and more than six years of experience in child protection. Professionals were required to distribute 50 sentences in a scoring sheet (Q‐sort methodology) with 11 points. The results were interpreted through the matrix of operationalisation of minimally adequate parenting. Three main answer strands revealed different focuses in sorts' configurations: the child, the procedures and the child's ecology. The clear difference between the factors could contribute to maintaining the child protection system as an adversarial one, and not as an effectively cooperative system. To promote team cohesiveness and intervention success, and to reinforce professionals' wellbeing and resilience, metacommunication on parenting assessment criteria is proposed as a determinant strategy.

Published: January 2024

AbstractThe olive oil sector generates a high quantity of biomasses every year, especially in the Mediterranean region. Olive pomace is the main one, but depending on the extraction and subsequent processing, other derived biomass by‐products are generated like pâté, exhausted olive pomace, olive stone, and residual pulp. Their sustainable valorization is crucial. Therefore, this review first conceptualizes the current situation of the olive oil sector and describes these biomasses from a qualitative and quantitative point of view. Second, information on the bioactive compounds they present, the technologies used for their extraction, and examples of applications for their extracts is provided. Third, since the extraction of bioactive compounds will generate new residual biomasses, this review takes a step forward by integrating the extraction step in biorefinery cascading schemes. It also analyzes the benefits of this integration, the contribution to a circular (bio)economy, and the achievement of sustainable development goals.

Published: January 2024

AbstractNeurocysticercosis is an infection of the central nervous system caused by the larval stage of Taenia solium. Although endemic in sub‐Saharan Africa, it is neglected but remains a significant cause of preventable seizure in adults. Its diagnosis is challenging and is frequently missed due to its variable clinical manifestations and lack of diagnostic facilities in most areas of sub‐Saharan Africa. This report discusses two cases of parenchymal neurocysticercosis in Ghanaians who presented to the emergency unit of a District Hospital with adult‐onset seizures. The two cases highlight the need for a high index of suspicion and also underscore the important role of neuroimaging in the evaluation of patients presenting with adult‐onset seizures in neurocysticercosis endemic areas. This is necessary for prompt detection and initiation of appropriate therapy in order to improve prognosis.

Published: January 2024

AbstractThe depolymerization of polyethers is a sustainable yet challenging opportunity for a circular economy in materials processing. While we recently identified silicon Lewis superacids as promising catalysts for this transformation, limited scope (e. g., terminal OH groups not tolerated) and strict requirements for anhydrous conditions hampered wider applicability. In the present work, the impact of different polyether structures and reaction conditions were evaluated. By doing so, the generality for structural variations was confirmed and substantial improvements made the depolymerization feasible for large‐scale applications under ambient conditions. Based on systematic experimental screenings, a refined mechanistic model of the depolymerization process is developed.
Anagostic Axial Interactions Inhibit Cross‐Coupling Catalytic Activity in Square Planar Pyridinophane Nickel Complexes

Published: January 2024

AbstractHerein, we report for the first time the use of the nitrogen‐based bidentate molecule [2.2]pyridinophane (N2) as a ligand for metal complexes. Additionally, its improved synthesis allows for electronic modification of the pyridine rings to access the new para‐dimethylamino‐[2.2]pyridinophane ligand (p‐NMe2N2). These ligands bind nickel in an analogous fashion to other pyridinophane ligands, completing the series of tetra‐, tri‐, and bidentate pyridinophane‐nickel complexes. The new compounds exhibit geometrically enforced C−H anagostic interactions between the ethylene bridge protons and the nickel center that are not present in other pyridinophane systems. These ethylene bridge groups also act as an unusual form of steric encumbrance, enforcing square planar geometries in ligand fields that would otherwise adopt tetrahedral structures. In addition, these anagostic interactions inhibit the catalytic performance in Csp3–Csp3 Kumada cross coupling reactions relative to other common bidentate N‐ligand platforms, possibly by preventing the formation of the 5‐coordinate oxidative addition intermediates.

Published: January 2024

AbstractElectrochemical epoxidation of olefins using water as an oxygen atom source is emerging as an alternative approach for an atom economic and sustainable method towards a highly selective synthesis of epoxides. We report an electrochemical procedure for epoxidation of cyclooctene using water as the sole oxygen atom source over a sodium dodecyl sulfonate (SDS) modified nickel hydroxide Ni(OH)2 catalyst directly grown on Ni foam. The SDS modification facilitates the mass transfer of cyclooctene towards the anode, thus achieving a 2.5‐fold higher conversion with more than 90 % selectivity towards the corresponding epoxide compared with pure Ni(OH)2 catalyst.

Published: January 2024

AbstractEncouraged by the successful fabrication of C60‐GNR (GNR=graphene nanoribbon) single‐molecule transistors in experiments, four Fe‐containing derived double‐layered devices of Fe@C60‐GNR are designed by employing different electrode linkages and their transport properties are investigated by using density functional theory (DFT) and nonequilibrium Green's function (NEGF) methods. Regardless of electrode connection, all these devices give rise to a smaller negative differential resistance (NDR) peak at V=0.2 and a higher peak at 1.2 V, suggesting their stable maneuverability as molecular devices and good candidates for developing on(off)‐off(on)‐on(off) current switches. The macroscopic NDR performance depends on the delocalization character and the crossing mechanism of the frontier orbitals. The peak‐to‐valley current ratios (Rmax) range from 454 to 2737, determined by the electrode linkage. Such a large Rmax‐value is necessary for developing dynamic random‐access memory (DRAM) cells. Encapsulating the Fe atom inside C60 not only improves the conductivity but also introduces the spin‐polarized transport property. The spin‐filtering efficiency (SFE) of almost all devices oscillates up and down in response to the bias voltage, indicating the possibility of designing on(off)‐off(on)‐on(off) spin switches and up‐down spin switches. All these fascinating properties provide an important clue for designing similar molecular devices with multiple functions by trapping magnetic transition metal atoms inside fullerenes.

Published: January 2024

AbstractThe environmental impact from the waste disposal has been widely concerned around the world. The conversion of wastes to useful resources is important for the sustainable society. As a typical family of wastes, biomass materials basically composed of collagen, protein and lignin are considered as useful resources for recycle and reuse. In recent years, the development of carbon material derived from biomasses, such as plants, crops, animals and their application in electrochemical energy storage have attracted extensive attention. Through the selection of the appropriate biomass, the optimization of the activation method and the control of the pyrolysis temperatures, carbon materials with desired features, such as high‐specific surface area, variable porous framework, and controllable heteroatom‐doping have been fabricated. Herein, this review summarized the preparation methods, morphologies, heteroatoms doping in the plant/animal‐derived carbonaceous materials, and their application as electrode materials for secondary batteries and supercapacitors, and as electrode support for lithium‐sulfur batteries. The challenges and prospects for the controllable synthesis and large‐scale application of biomass‐derived carbonaceous materials have also been outlooked.

AbstractHelical nanographenes have garnered substantial attention owing to their finely adjustable optical and semiconducting properties. The strategic integration of both helicity and heteroatoms into the nanographene structure, facilitated by a boron‐oxygen‐based multiple resonance (MR) thermally activated delayed fluorescence (TADF), elevates its photophysical and chiroptical features. This signifies the introduction of an elegant category of helical nanographene that combines optical (TADF) and chiroptical (CPL) features. In this direction, we report the synthesis, optical, and chiroptical properties of boron, oxygen‐doped Π‐extended helical nanographene. The π‐extension induces distortion in the DOBNA‐incorporated nanographene, endowing a pair of helicenes, (P)‐B2NG, and (M)‐B2NG exhibiting circularly polarized luminescence with glum of −2.3×10−3 and +2.5×10−3, respectively. B2NG exhibited MR‐TADF with a lifetime below 5 μs, and a reasonably high fluorescence quantum yield (50 %). Our molecular design enriches the optical and chiroptical properties of nanographenes and opens up new opportunities in multidisciplinary fields.

AbstractSaxitoxin (STX, 1) is a representative compound of paralytic shellfish toxins (PSTs) that are produced by marine dinoflagellates and freshwater cyanobacteria. Although several pathways have been proposed for the biosynthesis of STX, the order of ring and side chain hydroxylation, and formation of the tricyclic skeleton have not been well established. In this study, 12,12‐dideoxy‐decarbamoyloxySTX (dd‐doSTX, 2), the most reduced STX analogue having the tricyclic skeleton, and its analogues, 12β‐deoxy‐doSTX (12β‐d‐doSTX, 3), 12α‐deoxy‐doSTX (12α‐d‐doSTX, 4), and doSTX (5), were synthesized, and these compounds were screened in the toxic microalgae using high‐resolution LCMSMS. dd‐doSTX (2) and 12β‐d‐doSTX (3) were identified in the PSTs‐producing dinoflagellates (Alexandrium catenella, A. pacificum, and/or Gymnodinium catenatum) and in the cyanobacterium Dolichospermum circinale (TA04). doSTX (5), previously isolated from the dinoflagellate G. catenatum, was also identified in D. circinale (TA04). Furthermore, the conversion of 2 to 3, and 4 to 5, by SxtT with VanB, a reported Rieske oxygenase and its redox partner in STX biosynthesis, was confirmed. These results support that 2 is a possible biosynthetic precursor of STX, and that ring and side‐chain hydroxylations proceed after cyclization.
Efficient asynchronous federated learning with sparsification and quantization

Published: January 2024

SummaryWhile data is distributed in multiple edge devices, federated learning (FL) is attracting more and more attention to collaboratively train a machine learning model without transferring raw data. FL generally exploits a parameter server and a large number of edge devices during the whole process of the model training, while several devices are selected in each round. However, straggler devices may slow down the training process or even make the system crash during training. Meanwhile, other idle edge devices remain unused. As the bandwidth between the devices and the server is relatively low, the communication of intermediate data becomes a bottleneck. In this article, we propose time‐efficient asynchronous federated learning with sparsification and quantization, that is, TEASQ‐Fed. TEASQ‐Fed can fully exploit edge devices to asynchronously participate in the training process by actively applying for tasks. We utilize control parameters to choose an appropriate number of parallel edge devices, which simultaneously execute the training tasks. In addition, we introduce a caching mechanism and weighted averaging with respect to model staleness to further improve the accuracy. Furthermore, we propose a sparsification and quantitation approach to compress the intermediate data to accelerate the training. The experimental results reveal that TEASQ‐Fed improves the accuracy (up to 16.67% higher) while accelerating the convergence of model training (up to twice faster).

Published: January 2024

AbstractThe development of acid‐stable oxygen evolution reaction electrocatalysts is essential for high‐performance acidic water electrolysis. Herein, we report the results of one‐dimensional (1D) nanorods (NRs) IrCeMnO@Ir containing ~20 wt . % Iridium (Ir) as an efficient anode electrocatalyst, synthesized via a one‐step cation exchange strategy. Owing to the presence of 1D channels of the nanorod architecture and the unique electronic structure, the IrCeMnO@Ir exhibited 69 folds more mass activity than that of commercial IrO2 as well as over 400 h stability with only a 20 mV increase in overpotential. DFT calculations and control experiments demonstrated that CeO2 serves as an electron buffer to accelerate the kinetics of the rate‐determined step for the significantly enhanced activity and suppress the over‐oxidation of Ir species as well as their dissolution for impressively promoted stability under practical conditions. Our work opens up a feasible strategy to boost OER activity and stability simultaneously.

Published: January 2024

AbstractPennycress (Thlaspi arvense L.) is a winter annual weed species that is distributed globally in temperate regions. The possibility of pennycress inclusion in the corn–soybean cropping system in the midwestern United States has garnered increasing attention from farmers. Growing pennycress offers environmental benefits—reducing soil erosion and nitrate leaching, improving water quality, early‐season pollinator food, and economic benefits—higher seed oil percentage, increased net profit, crop diversification, and biodiesel/renewable jet fuel production. The prospect of pennycress as a cover/oilseed cash crop in the United States is supported by several private and public research institutions. Here, we have discussed the rise of pennycress as a breakthrough oilseed crop in the last decade and explored recent developments in pennycress genetics and genomics research, which could pave the way for pennycress improvement and sustainable pennycress inclusion in the midwestern United States.
