AbstractMany charged organic molecules behave as persistent and hazardous pollutants with harmful effects on human health and ecosystems. They are widely distributed related to their charged molecular structure that provides water solubility. In order to track the fate and behavior of such pollutants, charged dyes with specific absorption in the visible spectra serve as convenient model compounds. We provide a platform of smart adsorbers that efficiently remediate positively and negatively charged dyes (crystal violet and Amaranth) from water. Metal oxide nanoparticles serve as a core with an intrinsically large surface area. The surface potential was tuned towards positive or negative by decorating the cores with self‐assembled monolayers of dedicated long‐chained phosphonic acid derivatives. Selective remediation of the dyes was obtained with corresponding oppositely charged core‐shell nanoparticles. Mixed dye solution can be cleaned by a cascade approach or by applying both particle systems simultaneously. The removal efficiency was determined as a function of particle concentration via UV‐spectroscopy. The results of remediation experiments at different pH values and using superparamagnetic iron oxide nanoparticle cores lead to a simple process with recycling capability.
A Legendre spectral‐Galerkin method for fourth‐order problems in cylindrical regions
Authors: Zheng Jihui , An Jing 
Published: September 2023

AbstractA spectral‐Galerkin method based on Legendre‐Fourier approximation for fourth‐order problems in cylindrical regions is studied in this paper. By the cylindrical coordinate transformation, a three‐dimensional fourth‐order problem in a cylindrical region is transformed into a sequence of decoupled fourth‐order problems with two dimensions and the corresponding pole conditions are also derived. With appropriately constructed weighted Sobolev space, a weak form is established. Based on this weak form, a spectral‐Galerkin discretization scheme is proposed and its error is rigorously analyzed by defining a new class of projection operators. Then, a set of efficient basis functions are used to write the discrete scheme as the linear systems with a sparse matrix based on tensor product. Numerical examples are presented to show the efficiency and high‐accuracy of the developed method. Finally, an application of the proposed method to the fourth‐order Steklov problem and the corresponding numerical experiments once again confirm the efficiency and spectral accuracy of the method.

AbstractObjectiveThe aim of this study was to explore prospective relationships between changing patterns of BMI/waist to height ratio (WHtR) during adolescence and subsequent neurobehavioral development.MethodsIn this prospective cohort study, randomized stratified sampling was used to recruit six middle schools and 609 students in Shanghai, China. In Grades 6, 7, and 9, the Youth Self Report scale was used to assess student neurobehavioral status and anthropometric measurements were conducted to calculate BMI z scores and WHtRs. Longitudinal data were analyzed using latent class mixture modeling to delineate trajectories of BMI z scores (“stable,” “decreasing,” “rapidly increasing”) and WHtRs (“stable,” “rapidly increasing”), and their associations with neurobehavioral status in Grade 9 were assessed.ResultsIn Grades 6 through 9 (ages 11–15 years), the prevalence of overall obesity and abdominal obesity ranged from 10.7% to 13.0% and 13.0% to 19.8%, respectively. Compared with the stable BMI z score trajectory, the rapidly increasing BMI z score trajectory was longitudinally associated with delinquent behavior, aggressive behavior, and externalizing problems (incidence rate ratio: 1.564–1.613, adjusted p < 0.05). Compared with the stable WHtR trajectory, the rapidly increasing WHtR trajectory significantly predicted increased risks of social problems and delinquent behavior (incidence rate ratios: 1.776–1.967, adjusted p < 0.05). Significant associations of the rapidly increasing BMI z score/WHtR trajectories with subsequent neurobehavioral deficits were observed among girls (adjusted p < 0.05) but not among boys (adjusted p > 0.05).ConclusionsRapid increases in BMI or WHtR during adolescence could predict subsequent neurobehavioral deficits, especially for externalizing behaviors. Timely intervention for weight control may be considered to promote adolescent mental health.

AbstractIntroductionShenlingbaizhu granule, a Traditional Chinese Medicine prescription comprising Renshen, Gancao, and Shanyao, is widely consumed in China nowadays.ObjectiveThe study tries to propose pharmacopoeia quality markers (Q‐markers) to prevent counterfeiting involving Renshen, Gancao, and Shanyao.MethodologyA novel strategy, that is, library‐based ultra‐high‐performance liquid chromatography–quadrupole‐orbitrap mass spectrometry, was used to analyse the lyophilised aqueous powder of Shenlingbaizhu granule. Subsequently, quantum chemistry calculation and UV‐vis spectra scanning were also performed through theoretical or experimental approaches.ResultThirty‐two isomers have been strictly distinguished, especially positional isomeric isochlorogenic acid B versus isochlorogenic acid C, positional isomeric schaftoside versus isoschaftoside, positional isomeric ginsenoside Rg2 versus 20S‐ginsenoside Rg3, and stereoisomeric 20S‐ginsenoside Rg3 versus 20R‐ginsenoside Rg3. Seventeen compounds were unexpectedly observed, particularly scoparone and pectolinarigenin, while a total of 76 bioactive compounds have been putatively identified in the study. The quantum chemistry calculation and UV‐vis spectra scanning results revealed that glycyrrhizic acid, ginsenoside Re, ginsenoside Rb1, and diosgenin displayed different dipole moment values and maximum absorption wavelengths from each other.ConclusionThe study recommends glycyrrhizic acid, ginsenoside Re, ginsenoside Rb1, and diosgenin as four anti‐counterfeiting Q‐markers for the pharmacopoeia. The anti‐counterfeiting Q‐markers can be detected using conventional HPLC. The observation of 17 unexpected compounds updates our knowledge regarding the bioactives of Shenlingbaizhu granule.
The Good Behavior Game for students with special educational needs in mainstream education settings: A scoping review
Authors: Jornevald Maria , Pettersson‐Roll Lise , Hau Hanna 
Published: September 2023

AbstractThe Good Behavior Game (GBG) is a classroom management strategy that consistently demonstrates its ability to promote positive behaviors and peer relations among students, with immediate and long‐term benefits. This scoping review aimed to provide an overview of peer‐reviewed research on the GBG specifically focused on students with special educational needs (SEN) in mainstream education settings. Following a systematic search‐and‐selection procedure, 30 studies were included, 26 with an experimental design and 4 with a qualitative/mixed‐methods design. SEN participants were mainly subgroups of students with baseline assessments of emotional‐behavioral difficulties; there was, however, substantial clinical and methodological heterogeneity across studies. Integrative findings from quantitative and qualitative studies indicate that the GBG benefits most students with SEN in mainstream settings, while results for students with severe socio‐behavioral difficulties are ambiguous. We identified a paucity of research on students with neurodevelopmental diagnoses such as attention deficit hyperactivity disorder or autism spectrum disorder, as well as on the perspectives of students and teachers and challenges associated with the GBG for students with severe difficulties. Schools implementing the GBG should be aware that some students may need individual adaptations to participate in the GBG, and teachers may need support to implement these adaptations.
Self‐regulation and procrastination in college students: A tale of motivation, strategy, and perseverance

Published: September 2023

AbstractProcrastination is a delay in an intended course of action and, thus, a self‐regulation failure hindering growth and well‐being. Contrarily, self‐regulation is a set of cognitive and metacognitive skills and strategies supporting goal‐directed behavior. There is ongoing discussion regarding the extent to which (and the ways in which) promoting self‐regulation may counteract procrastination. On the one hand, it is argued that procrastination is linked with stable personal dispositions; on the other hand, it is said that this problematic behavior is associated with contextual influences. To deepen the understanding of these relationships, we used structural equation modeling (SEM) to test a theory‐driven model integrating four self‐regulation factors (goal setting, decision making, persevering, and learning from mistakes) and two measures of procrastination (irrational and academic). We hypothesized that goal setting, decision making, and perseverance would sequentially mediate between learning from mistakes and procrastination outcomes, thus, suggesting that cognitive‐motivational (learning from mistakes, goal setting), strategic (decision making), and volitional (perseverance) factors may all be necessary for successful self‐regulation, which could potentially be promoted by contextual influences. Participants of the present study were 433 Chilean university students (304 women, 129 men, M = 20.74 years, SD = 2.86) who completed measures for procrastination and self‐regulation. Findings support the important roles of goal setting and perseverance for successful self‐regulation and suggest that goal setting may mediate the effects of learning from mistakes on perseverance and decision making; whereas perseverance may mediate the effects of goal setting and decision making on procrastination variations. These results suggest that the negative effects of motivational and strategic factors of self‐regulation on procrastination may depend at least partly on the abilities to improve goals and persevere. Taking into account these critical roles in dealing with procrastination, it seems appropriate to support college students' self‐regulation skills and strategies, raising awareness about the indispensability of adequate goal setting and persistence in following through with intended courses of action.

Published: September 2023

AbstractBackgroundBehavioral cough suppression therapy (BCST) with a speech–language pathologist is a common treatment for chronic nonspecific cough (a.k.a., tic cough) in children. Yet, the outcomes and duration of pediatric BCST have eluded formal investigation. This study examined whether BCST improves cough in children with nonspecific cough and factors that predict the course of treatment. Additionally, the cough characteristics and comorbidities associated with the condition were examined.MethodsA retrospective, observational cohort design was utilized. Cough characteristics, medical history, and BCST treatment details and outcomes for 151 children were extracted from the electronic medical record of a large outpatient pediatric otolaryngology clinic.ResultsCough was dry and onset unaccompanied by illness in most cases. Roughly half of patients reported gradual onset and cough proceeded by tickle. On average, patients experienced symptoms for 19 months (SD = 20.09) before diagnosis. Rates of comorbid General Anxiety Disorder were elevated compared to pediatric norms. Additionally, high rates of asthma (22.1%), reflux (62.3%), and disordered sleep breathing (19.2%) were observed. Common findings on laryngoscopy included interarytenoid edema and erythema. Vocal fold changes were observed in 22.9% of children. BCST reduced cough in 92.5% of patients following an average of 1.7 sessions. Comorbid behavioral health diagnoses (p = 0.013) or induced laryngeal obstruction symptoms (p = 0.025) were significant predictors of increased therapy sessions. Cough proceeded by tickle significantly predicted fewer sessions in therapy (p = 0.011).InterpretationAlthough randomized clinical trials are needed, these data suggest that BCST is a low‐risk, effective treatment for children with nonspecific cough.
Effects of encapsulation of manganin gauges on the pressure profiles from shock initiation experiments
Authors: Miao Feichao , Jiang Tao , Li Dandan , Zhang Xiangrong , Zhou Lin 
Published: September 2023

AbstractThe Lagrangian test can measure the shock initiation process of explosives for different incident shock pressures. The manganin gauges record pressure histories for several DNAN‐based melt‐cast explosives. The encapsulation of the gauges results in three types of characteristic signals: (1) a step signal on the low‐pressure shock front, (2) a flatten Von Neuman's (VN's) spike on the high‐pressure shock front, and (3) a V‐shape signal behind the shock front. To reveal the mechanism underlying these characteristic signals, a one‐dimensional Lagrangian hydrocode, was used to simulate the propagation of a sustained shock in both ideal and non‐ideal systems. The simulation results show that the impedance mismatch between encapsulation material and explosives is the main reason for the three characteristic signals. The calibration of shock initiation model should take the encapsulation material into account so as to determine shock initiation model parameters accurately.

AbstractBACKGROUNDSex pheromones have proven to be a viable tool for monitoring and controlling pests and is an important part of integrated pest management (IPM). The noctuid moth Macdunnoughia crassisigna Warren poses a significant threat as a defoliator pest, impacting soybean and cruciferous vegetable production and quality in East Asia. However, a lack of comprehensive knowledge about its sexual chemical signaling hampers the development of semiochemical‐based IPM approaches for M. crassisigna.RESULTSWe first determined the mating rhythms of M. crassisigna. We then collected pheromones from the sex glands of virgin females at the mating peak and analyzed their components using gas chromatography–electroantennogram detection analysis. The results showed that three components elicited significant electrophysiological responses in male antennae. Gas chromatography–mass spectrometry analysis characterized these components as (Z)‐7‐dodecene acetate (Z7‐12:OAc), (Z)‐9‐tetradecene acetate (Z9‐14:OAc), and (Z)‐11‐hexadecen‐1‐ol (Z11‐16:OH). Further field experiments indicated that the mixture of Z7‐12:OAc and Z9‐14:OAc at a ratio of 3:1 displayed significant attractivity to males, confirming its role as a putative sex pheromone of M. crassisigna. Long‐term monitoring tests showed that traps baited with these pheromone lures effectively mirrored the population dynamics of M. crassisigna.CONCLUSIONThis study successfully identified and validated the sex pheromone released by female M. crassisigna and formulated potent sex lures for field‐based pest monitoring. These findings enriched our understanding of chemical communication in Noctuidae and laid a foundation for developing practical monitoring and control methods against M. crassisigna. © 2023 Society of Chemical Industry.
Commercial‐scale removal of short‐chain PFAS in a batch‐wise adsorptive bubble separation process by dosing with cationic co‐surfactant
Authors: Stevenson Paul , Karakashev Stoyan I. 
Published: September 2023

AbstractStudies performed by Burns et al. in 2021 and 2022 demonstrated that a three‐stage batch‐wise adsorptive bubble separation process, surface active foam fractionation (SAFF), is effective at removing most per‐ and polyfluoroalkyl substances (PFASs) from contaminated groundwaters and landfill leachates. However, PFAS species with very low adsorption coefficients to bubble surfaces are difficult to remove, which is parallel to the difficulties in removing short‐chain PFAS in granulated activated carbon beds and other solid media. It is well known that the adsorption coefficient to bubble surfaces improves in the presence of electrolytes in solution and it has previously been shown that this improves the removal of PFAS. By developing a correlation for the removal percentage of one species or another of PFAS due to SAFF in commercial‐scale processes as a function of the adsorption coefficient, it is possible to generally estimate the removal percentage of any PFAS. The addition of a cationic co‐surfactant, cetrimonium bromide, to the feed can significantly further improve the adsorption coefficient and, as a consequence, materially improve the removal of short‐chain PFAS due to SAFF. A method for estimating this improved performance is in qualitative agreement with plant trials of SAFF at a North American site with a history of groundwater contamination due to the use of aqueous film forming foams firefighting foams, but the precise improvements appear to be dependent upon the concentration of the added co‐surfactant. The required concentration of co‐surfactant is significantly larger than might be expected on charge equivalence considerations, and this may be due to its consumption by other species in the feed, including PFAS that have not been accounted for. It is noted that the SAFF process may not be true foam fractionation and may, instead, be a bubble fractionator, both of which can be collectively described by the term “adsorptive bubble separation processes.”

AbstractA benzothiazole fluorescent probe (probe 1) was developed for the determination of carboxylesterase and carbamate pesticides. The probe used benzothiazole as the fluorescent group and chlorophenyl acetate as the recognition group. The recognition mechanism of probe 1 for carboxylesterase was based on the enzymatic hydrolysis of chlorophenyl acetate by carboxylesterase. The solution of probe 1 gradually changed from light blue to dark blue as the concentration of carbamate pesticide increased. Probe 1 could detect the concentration of carbamate pesticide based on the linear functional relationship between the R/B*G (red, blue, green) value of the probe 1 solution photo and the concentration of carbaryl without professional personnel and equipment. Additionally, probe 1 was successfully used to detect the concentration of carbaryl in actual samples based on the curve function relationship between the fluorescence intensity of probe 1 at 434 nm and the concentration of carbaryl.
