Published: October 2022

The use of Immersive Virtual Reality for the teaching and learning of mathematics is a line of growing interest, where empirical research is needed on the impact of its inclusion in the classroom. We present a study carried out with student teachers, in which NeoTrie VR software is used in an experimental group to work on the notion of polyhedron, following the Vinner framework. The analysis of quantitative data shows the most common errors made by students when identifying the classes to which a set of three-dimensional figures belong. The contrast of results of the experimental group with a control group yields significant differences, which imply that working with the software contributes to the acquisition of a richer and more connected mental image of the concepts studied. The students of the experimental group have been able to identify to a greater degree the relevant characteristics of the polyhedrons, their types and connections between them, as well as to reduce the errors detected in the initial test.

Det usikre som premiss for pedagogisk arbeid i barnehagen
Authors: Eriksen Marte 
Published: October 2022

ResuméDenne artikkelen handler om det usikre som fenomen og om hvordan det usikre er til stede i pedagogisk praksis og i pedagogens relasjon til barnet. For å få en større forståelse av det usikre, undersøkes hva barnehagelæreres refleksjoner om barnehagens hverdagsliv kan fortelle om det usikre som premiss for pedagogisk arbeid. Det empiriske materialet er barnehagelæreres refleksjoner fra fire fokusgruppeintervjuer. I analysen og diskusjonen om det usikre trekkes det veksler på Hannah Arendts begrep om menneskelig handling og Emmanuel Lévinas’ begrep om alteritet.
AbstractThe uncertain as a premise for pedagogical work in kindergartenThis article is about doubt and uncertainty as a pedagogical phenomenon. It explores uncertainty as part of pedagogical practice, and the pedagogue’s relationship to the child. In order to deepen the understanding of “the uncertain”, pedagogue’s reflections on uncertainty as a pedagogical premise in ECEC everyday life are explored. The empirical material consists of ECEC teacher’s reflections from four focus group interviews. The analysis and discussion of the uncertain draws on Hannah Arendt’s concept of human action, and Emmanuel Lévinas’s philosophy about the Other.

Published: October 2022

ResuméStudiens syfte är att undersöka hur yrkesverksamma i fritidshem beskriver sitt arbete, sin trivsel, de inkluderande arbetssätt som används och samverkan. Detta görs med teoretisk utgångspunkt i förklaringsmodellen formuleringsarenan, transformerings- och medieringsarenan, och realiseringsarenan med fokus på vad fritidshemmets uppdrag blir i pedagogisk praktik. Data samlades in genom enkäter med yrkesverksamma (N=63) i fritidshem från olika orter i Sverige. Studiens resultat påvisar att de har ett varierat arbete, att de trivs, att de erbjuder inkludering och att de, med få undantag, sätter in stödinsatser. Mindre än hälften av dem beskriver att de erbjuds handledning och rådgivning från specialpedagog eller annan profession med specialpedagogiska kunskaper, samt att de samverkar med elevhälsa. Fritidshemmets resurser beskrivs i viss mån som otillräckliga och stödinsatserna kan många gånger anses vara för få. Förslag till vidare forskning diskuteras.
AbstractSchool-age educare teachers’ work, well-being, inclusive education strategies and collaboration: a survey The aim of this study is to investigate how professionals in School-age educare (SAEC) describe their work environment, well-being, collaboration and the education strategies used. This is done by means of a theoretical understanding model including a formulation arena, a transformation and mediation arena and a realisation arena where the focus is on the realisation arena. Empirical data was collected through surveys with professionals (N=63) in SAEC working in different Swedish cities. The result of the study shows that they have a multifaceted work, that they are content/happy, that they provide inclusive education and support measures. Less than half of those surveyed describe that they receive adequate supervision and advice from a special needs educator or other profession with special needs education knowledge and that they collaborate with the School health services. The resources of the SAEC are to some extent perceived as insufficient and the support measures are often too limited. Suggestions for further research are discussed.
About Time
Authors: Friedman William 
Published: October 2022

In About Time, William Friedman provides a new integrated look at research on the psychological processes that underlie the human experience of time. Few intellectual problems are as intriguing or as difficult as understanding the nature of time. In About Time, William Friedman provides a new integrated look at research on the psychological processes that underlie the human experience of time. He explains what psychologists have discovered about temporal perception and cognition since the publication of Paul Fraisse's The Psychology of Time in 1963 and offers fresh interpretations of their findings.
In particular he shows that the experience of time depends on many different psychological processes and that it is essential to divide temporal experience into component categories in order to understand these processes.
In chapters on perception and memory, Friedman discusses our impressions about the rate of time's passage and our ability to localize memories in time. He takes up representation and orientation, our ability to build mental representations of the time structures that surround us and to view these patterns from the unique perspective of the present moment. Moreover he shows that we can learn a great deal about the psychological basis of temporal experience by studying the development of this knowledge in children and the way in which views of time vary by culture, personality type, and kind of psychopathology.

Globalisation and Rising Obesity in Low-Middle Income Countries
Authors: Obasuyi Osamudiamen Cyril 
Published: October 2022

While globalisation is a complicated term, evidence shows that increasing political and socio-economic connections, which is a hallmark of globalisation, dictate countries' health and economic decisions. These decisions significantly modify individuals' material circumstances and behavioural activities and lead to physical or psychological expression of disease.
In 2017, the WHO reported that over 4million people died from being overweight or obese. In the last four decades, the rates of obesity, especially in children and adolescents, have quadrupled from 4%-18% globally; in 2016, over 340 million children were either overweight or obese.
Non-traditional global health governance actors-whose influence in determining economic and global health decisions has risen in the last decades- have consistently furthered economic interests, which is, in part, fueling the obesity pandemic.
This paper argues that the increasing economic integration from globalisation, with the aid of the current global health governance landscape, drives the current obesity pandemic by worsening the social determinants of health, perpetuating inequality, and promoting unhealthy changes in the population's economic and socio-cultural environment.

AbstractThe use of track‐etched membranes allows further fine‐tuning of transport regimes and thus enables their use in (bio)sensing and energy‐harvesting applications, among others. Recently, metal–organic frameworks (MOFs) have been combined with such membranes to further increase their potential. Herein, the creation of a single track‐etched nanochannel modified with the UiO‐66 MOF is proposed. By the interfacial growth method, UiO‐66‐confined synthesis fills the nanochannel completely and smoothly, yet its constructional porosity renders a heterostructure along the axial coordinate of the channel. The MOF heterostructure confers notorious changes in the transport regime of the nanofluidic device. In particular, the tortuosity provided by the micro‐ and mesostructure of UiO‐66 added to its charged state leads to iontronic outputs characterized by an asymmetric ion current saturation for transmembrane voltages exceeding 0.3 V. Remarkably, this behavior can be easily and reversibly modulated by changing the pH of the media and it can also be maintained for a wide range of KCl concentrations. In addition, it is found that the modified‐nanochannel functionality cannot be explained by considering just the intrinsic microporosity of UiO‐66, but rather the constructional porosity that arises during the MOF growth process plays a central and dominant role.

AbstractOwing to high antibiotic resistance and thermotolerance, bacterial biofilm infections (BBIs) are refractory to elimination. Iron is essential for bacterial growth and metabolism, and bacteria can thus accumulate iron from surrounding cells to maintain biofilm formation and survival. Consequently, iron deficiency in the biofilm microenvironment (BME) leads to the functional failure of innate immune cells. Herein, a novel antibiofilm strategy of iron‐actuated Janus ion therapy (IJIT) is proposed to regulate iron metabolism in both bacterial biofilm and immune cells. A BME‐responsive photothermal microneedle patch (FGO@MN) is synthesized by the growth of Fe3O4 nanoparticles on graphene oxide nanosheets and then encapsulated in methacrylated hyaluronic acid needle tips. The catalytic product of ·OH by FGO@MN in BME disrupts the bacterial heat‐shock proteins, coercing biofilm thermal sensitization. As synergistic mild photothermal treatment triggers iron uptake, the intracellular iron overload further induces ferroptosis‐like death. Moreover, iron‐nourished neutrophils around BME can be rejuvenated for reactivating the suppressed antibiofilm function. Thus, more than 95% BBIs elimination can be achieved by combining heat stress‐triggered iron interference with iron‐nutrient immune reactivation. Furthermore, in vivo experiments validate the scavenging of refractory BBI after 15 days, suggesting the promising perspective of IJIT in future clinical application.

AbstractDevelopment of a flexible, transparent, and air‐permeable dopamine (DA) sensor is highly desirable for fully integrated optoelectrochemical probes, which can provide a useful tool for closed‐loop control and monitoring neural activities. Herein, a 3D freestanding architecture, which integrates a flexible and transparent metallic micromesh as the “core” with DA sensitive poly(3,4‐ethylenedioxythiophene)‐poly(styrenesulfonate) (PEDOT:PSS) as the “shell,” has been developed for DA monitoring. The freestanding micromesh electrode shows not only high mechanical flexibility (without apparent performance variation after 100 bending times), high optical transparency (≈85% at 550 nm), and air permeability (≈2600 mm s−1 at 10 Pa), but also excellent DA sensing performance such as a sensitivity up to 1650 µAcm−2 mM−1, wide linear range from 1 × 10−6 to 1000 × 10−6 m, a low limit of detection (LOD) of 0.27 × 10−6 m, high selectivity and high stability. The outstanding performance may arise from the core‐shell micromesh configuration, which combines high electrical conductivity of the Ni micromesh and high electrocatalytic activity of the PEDOT:PSS layer for DA oxidation. Such 3D freestanding architecture offers a simple and effective methodology to construct implantable biosensors for monitoring of DA and other neurotransmitters in the brain.

Published: October 2022

AbstractArtificial synapses have attracted extensive attention due to their capacity to circumvent the inherent restrictions of Von Neumann computing architecture. Although electrolyte‐gated synaptic transistors (EGSTs) have been enabled to emulate the essential synaptic plasticity, the corresponding neurological applications have been restricted by the lack of inhibitory synaptic response and the subsequent low asymmetric non‐linearity factor. Here, Mg‐doped SnO2 (Mg:SnO2) EGSTs via a low‐cost and facile solution method are fabricated. With both excitatory and inhibitory response modes, the improved MgSnO EGSTs display variable synaptic plasticity, with featured characteristics such as excitatory post‐synaptic current (EPSC), inhibitory post‐synaptic current (IPSC), paired pulse facilitation (PPF), paired pulse depression (PPD), spiking rate dependent plasticity (SRDP), and spike timing dependent plasticity (STDP). For the University of California at Irvine image, a simulated artificial neural network built on MgSnO EGSTs may achieve a learning accuracy of 92.3%. In addition, digital logic processing, Pavlovian dog's experiment have all been realized by the newly designed MgSnO EGSTs. These results highlight the potential of the MgSnO EGSTs for next‐generation artificial intelligence systems.

AbstractOrganic/inorganic hybrid artificial functional layer (AFL) designs of Zn anode have witnessed good progress in stabilizing the Zn anode. However, such processes remain uncapable of simultaneously providing durable protection and fast Zn2+migration, especially in high‐rate scenarios. Herein, intrinsic hydrogen‐bond donor (HBD)‐lined organophosphate superionic nanochannels are initially engineered to address this challenge. Due to unique ordered nanochannels with a smaller diameter than that of hydrated Zn2+ions and polyanions, hydroxymethyl Zn phosphates (Zn(O3PCH2OH, ZnOPC) are first considered for AFL design. The small size can provide an interception for polyanions. Density functional theory calculation indicates that ZnOPC nanochannels possess a 35% lower Zn2+migration energy barrier than conventional Zn phosphate, highly consistent with tested results. Additionally, as HBDs, rich ‐CH2OH groups located at nanochannels impose a targeted hydrogen‐bonding interaction with water molecules. Consequently, at an ultrahigh current density up to 50 mA cm−2, the Zn@ZnOPC anode shows a 36% lower overpotential than that of the bare Zn anode. As‐assembled Zn @ ZnOPC//NaV3O8· 1.5H2O full cells exhibit an ultralong lifespan of 20 000 cycles at 20 A g−1, with a low capacity‐decay of 0.016% per cycle. This work features a targeted hydrogen bonding‐enhanced desolvation effect occurring in organophosphate superionic nanochannels, which would enlighten to explore reliable fast‐charging aqueous batteries.
Residue decomposition dynamics in mixed ratios of two warm‐season cover crops
Authors: Dorissant Larousse , Brym Zachary T. , Swartz Stacy 
Published: October 2022

AbstractCover crop residue management has gained attention over the past few decades due to the potential of cover crop residues to provide soil cover and nutrient availability for subsequent crops. Nutrients released from cover crop residues depend on the nutrient composition of plant tissue and ensuing rates of mineralization. To evaluate the rate of carbon (C) and nitrogen (N) mineralization from cover crops, a field decomposition experiment was conducted in a humid subtropical agricultural field. Residues of two warm‐season cover crops, sunn hemp (Crotalaria junceaL.) and sorghum sudangrass (Sorghum bicolorL. ×S. bicolorvar. Sudanese), were placed in litterbags at various mixture ratios on the soil surface to quantify the amount of N and C released from the residues over 56 d. Residue biomass decomposition followed decay patterns that were similar despite treatment mixtures of cover crop ratios. The initial ratio of cover crop material in the litter mixture influenced early N release where ratios with increasing sunn hemp increased N decomposition. The majority of residue breakdown (50–75%), and C (50–75%) and N (65–75%) decomposition occurred during the first 7 d for all the treatments. A minor fraction of residue remained (10–14%) at Day 56, with 10–14% C and 7–25% N. The 25% N remained in the sole sorghum sudangrass treatment. These results indicate that N from legume cover crops may not be available to subsequent crops in humid subtropical soils lacking the capacity to retain nutrients leached out of cover crop residue, though small fractions of dry matter may remain.

Published: October 2022

AbstractAs genetic testing becomes more available, its utilization as an early diagnostic tool in nephrology is more common. The objective of the study is to examine diagnostic agreement between the renal biopsy findings and genetic diagnoses. A retrospective study was conducted in February 2022. A total of 28 patients had both genetic diagnosis and histologic results (n = 1 nephrectomy, n = 27 biopsy). We collected clinical, renal biopsy findings, and genetic information. The relationship between the histologic findings and the genetic diagnoses was classified as: concordant, nonspecific, and discordant. A total of 15 males and 13 females were included (mean age = 9.6 years). Clinical suspicion of Alport syndrome was the most common reason for referral (n = 11, 39.3%), followed by nephrotic syndrome (n = 8, 28.5%), “other” (n = 6, 21.4%), cystic kidney disease (n = 1, 3.6%), isolated hematuria (n = 1, 3.6%), and non‐nephrotic proteinuria (n = 1, 3.6%). The overall concordance rate between renal histologic and genetic diagnoses was 71.4% (20/28), nonspecific biopsy results were observed in 17.9% (5/28), and discordant results were observed in 10.7% (3/28). All patients referred for suspected Alport Syndrome had pathogenic/likely pathogenic variants in one of the COL4A genes. Two cases of Lowe syndrome and one of PAX2‐associated nephropathy had discordant histology findings. Agreement between renal histologic findings and genetic results varies based on the reason for referral. There was a complete agreement for patients referred for Alport Syndrome; However, there were examples that renal biopsy showed secondary findings that were not specifically associated with the underlying genetic results.

AbstractAn efficient and transition metal‐free C(sp3)−H sulfonylation method is described for the synthesis of 2‐sulfolmethyl quinolines from 2‐methylquinolines and the inexpensive sulfonyl hydrazides. Generally, this protocol uses KI as an additive in the presence of the oxidant tert‐butyl peroxybenzoate (TBPB), an efficient and compatible benign method that delivers 2‐sulfolmethyl quinolines products in moderate to good yields.
Human maxillary sinus size, shape, and surface area: Implications for structural and functional hypotheses

Published: October 2022

AbstractObjectivesAlthough research into human maxillary sinus (MS) morphology has overwhelmingly focused on sinus volume, other aspects of morphology (e.g., overall shape, mucosal surface area) factor prominently in hypotheses regarding MS form and function. Here, we investigate MS volume in conjunction with measures of MS shape and surface area in a large, diverse sample of modern humans. We test whether variation in MS volume is associated with predictable changes in MS shape (i.e., allometry) and investigate the influence of MS size‐shape scaling on mucosal surface area dynamics.Materials and MethodsMeasures of MS volume and surface area were obtained from computed tomographic (CT) scans of 162 modern human crania from three ancestral backgrounds—Equatorial Africa, Europe, and East Asia. 3D coordinate landmarks and linear measurements were also collected. Multivariate analyses were employed to test for associations between MS volume and other morphological variables.ResultsSignificant associations between MS volume and 3D shape were identified both across and within the subsamples. Variation in MS volume was found to predominantly relate to differences in MS height and width dimensions relative to MS length. This pattern of allometric scaling was found to differentially influence total mucosal surface area and the SAV ratio.ConclusionThis study suggests that variation in MS volume is disproportionately mediated by MS width and height dimensions. This finding has implications for hypotheses which structurally link MS morphology to craniofacial ontogeny and those which suggest that MS morphology may perform adaptive physiological functions.
