AbstractIntroductionIdentifying subgroups of Temporary (alcohol) Abstinence Challenge (TAC) participants may offer opportunities to enhance intervention effectiveness. However, knowledge about such subgroups is missing. This study aimed to (i) describe a TAC population; (ii) identify subgroups of participants based on determinants of changes in drinking behaviour; and (iii) characterise subgroups in terms of sociodemographic and other characteristics.MethodsData from 3803 Dutch TAC participants were analysed to identify subgroups using three‐step Latent Class Analysis. Classes were based on determinants of changes in drinking behaviour (i.e., drinking refusal self‐efficacy, craving and behavioural automaticity) and were characterised by sociodemographic characteristics, drinking behaviour, previous participation in TACs, self‐reported health and life satisfaction.ResultsThe majority of TAC participants were female, highly educated, employed, 53 years old on average, participated in previous TACs and reported relatively high alcohol use. Four classes of participants were identified: (i) ‘ordinary drinkers’ (49.0%); (ii) ‘drinkers in control’ (21.4%); (iii) ‘habitual drinkers with perceived control to refuse’ (18.4%); and (iv) ‘drinkers not in control’ (11.2%). Class 2 drank least often and non‐excessive volumes, while other classes typically drank 4 or more days per week and 3 to 4 glasses per drinking day, with the highest alcohol use found in class 4.Discussion and ConclusionsDifferent configurations of determinants in this study's four subgroups may require different intervention approaches and might inform personalised support. Future research is needed to examine the predictive value of these subgroups on post‐challenge drinking behaviour to assess support needs and participation value.
Pay for digitalization: The relationship between digital transformation and payment disparity

Published: August 2024

AbstractUsing a sample of China's A‐share listed firms from 2016 to 2021, this study empirically examines the influence of digital transformation on the pay gap within firms. Based on the optimal salary contract theory, we posit that digital transformation widens within‐firm pay gap. Conversely, based on the managerial power theory, we posit the competing hypothesis that digital transformation is negatively correlated with the pay gap. Our findings support the optimal salary contract theory, suggesting that digital transformation is positively related to the pay gap, as evidenced by an increase in executive compensation rather than a decrease in the pay of rank‐and‐file employees. These findings are robust to various checks, including alternative measurements, quantile regression model, Heckman selection model, and IV‐2SLS method. Further tests reveal that the positive relationship between digital transformation and the pay gap is more pronounced in labor‐intensive enterprises and those with lower risk‐taking abilities. This study argues that a widening internal pay gap in the digital era is a rational market choice, as evidenced by the positive impact of the within‐firm pay gap resulting from digital transformation on firms' performance. This study extends our understanding of the impact of digital transformation and enriches the literature on compensation contract design.
The role of stock liquidity in blockholder governance: Evidence from corporate social responsibility
Authors: Freund Steven , Phan Hieu V. , Sun Lingna S. , Vo Hong 
Published: August 2024

AbstractWe use decimalization of the tick size, which exogenously increases stock liquidity and thereby heightens blockholder governance, to identify its effect on corporate social responsibility (CSR). We find that enhanced blockholder governance after decimalization leads to lower excessive CSR performance and higher firm value. Compared to active blockholders, passive blockholders, relying on the threat of selling shares and exiting, drive our results. The inverse relationship between blockholder governance and CSR is more pronounced for firms with poor corporate governance prior to decimalization. Our evidence suggests that blockholder exit threat can serve as a governance device to alleviate agency‐driven CSR.
Educational Exit and the Pursuit of a Happy Childhood Among Singaporean Middle‐Class Families
Authors: Göransson Kristina 
Published: August 2024

ABSTRACTOn the basis of ethnographic fieldwork in Singapore, the article explores the tension between children's academic success and emotional wellbeing, and the ways in which middle‐class parents navigate these conflicting aspirations. It delves into families with young children who pursue alternative lifestyles by moving abroad to a presumably less stressful environment or by homeschooling their children. The study aims to understand how parents who ‘opt out’ perceive their children's future and the sacrifices they make in pursuing alternative education for their children. Decisions were made to ‘protect’ the child from the potentially negative effects of a competitive education system, while pursuing an alternative childhood and school–life balance. East Asian education systems are globally renowned for their high academic standards and for producing students who score at the top on international assessment tests and rankings. In this context, alternative educational pursuits are both less established and less well understood, yet they are central to understanding emerging aspirations of wellbeing as well as the reconfiguration of conventional ideals of upward social mobility.
Influence of adolescent sexual communication on respect for sexual and gender diversity and its impact on the meaning of life
Authors: Quiceno Anlly Melissa Patiño , Boza Malena Portal , Martínez Gabriel Alfonso Pacheco 
Published: August 2024

AbstractThis article, which addresses the relationships between the meaning in life, sexual communication in adolescence and respect for sexual and gender diversity, is based on theories that suggest connections between the underlying constructs. The methodology employed uses microdata from the National Survey on Sexual and Gender Diversity ENDISEG 2021, conducted by INEGI in Mexico, which are analyzed through structural equation modeling. When the structural model was validated using the bootstrapping technique, the results showed that the estimate of the relationship between sense of life and sexual communication in adolescence was 0.642, indicating that this relationship is not statistically significant. Similarly, the relationship between respect for sexual and gender diversity and sexual communication in adolescence showed a value of 0.099, reflecting that this relationship is not statistically significant. In contrast, the relationship between sense of life and respect for sexual and gender diversity obtained a value of 0.000, showing the existence of an effect, that is, that the relationship is statistically significant. In conclusion, the tensions inherent in adolescence, as well as cultural and social factors, introduce important debates that need to be considered when addressing these phenomena. This complexity highlights the need for a holistic approach that distinguishes the diversity of experiences and contexts that influence adolescent development and impact on adulthood.
The Good Death in Early Modern Europe
Authors: Klestinec Cynthia , Manning Gideon 
Published: August 2024

ABSTRACTThe inevitability of death does not change its variability. In The Hour of Our Death (1981), Philippe Ariès positioned the sudden, unexpected, mass death of epidemics (especially from the Black Death) against the personalized, domesticated death for which one had time to prepare. The domesticated death, so he argued, appeared during a specific epoche of European history and was an historical inflection point, coinciding with the 18th century Enlightenment. Ariès looked unfavorably at this climax for what he saw as a process of de‐spiritualization, waning of faith, and the beginnings of commercialization and medicalization of death. Since his publications, scholars from a range of fields—history, anthropology, literature, religion, and art—have sought to address the omissions, exaggerations, and misleading claims in Ariès' account and, in doing so, have developed a rich field studying the cultural history and significance of death. Now situated in a transdisciplinary space, studying the good death and the tradition of ars moriendi (the art of the dying well) offers new perspectives and answers new questions about death. Although there is much that could be discussed, the focus here will be on recent trends in scholarship on the tradition of ars moriendi and its relationship to the interrelated histories of burial, the role of clerical and lay comforters, and the role of physicians as well as the historical and religious‐philosophical problems of the prolongation of life and sudden death.
Hydration mechanism of hydrated magnesium citrate: The effects of MgCl2
Authors: Chen Jianjun , Xiao Guoqing , Ding Donghai 
Published: August 2024

AbstractIn this study, the evolutions of kinetic parameters, such as hydration temperature, pH, and electrical conductivity, were observed to investigate the hydration mechanism of hydrated magnesium citrate (HMC). Additionally, the effects of MgCl2 on the hydration behavior of HMC and the working performance of its bonded castables were also investigated. The results show that the hydration mechanism of HMC is dissolution–precipitation, and its hydration product is magnesium citrate tetrahydrate [Mg(H2O)6] [MgC6H5O7(H2O)n]2∙(8‐2n)H2O. The hydration process of HMC is controlled by the concentration of the C6H6O72− ions. MgCl2 could inhibit the ionization of HMC, thereby delaying the hydration progress of HMC. The second exothermic peak was delayed from 1 to 4.8 h with increased MgCl2 content to 1.0 wt.%. The working performance of HMC‐bonded castables could be improved by adding MgCl2. After adding MgCl2, the setting time, flow value, and cold modulus of rupture of HMC‐bonded castables increased by 26.7%, 25.2%, and 8.8%, respectively, while the porosity decreased by 12%.

AbstractThe tribological performance of the tungsten carbide substrate (WC‐Co), improved by ceramic coatings, is still being reported in new studies that have been carried out to date. It has become a hot research topic that are widely applied in hard material research, especially in the tools manufacturing fields. This study was conducted to investigate the wear characteristics of a commercial cemented carbide tool (WC‐Co) coated with a physical vapor deposition chromium‐vanadium nitride film (CrVN), followed by a boriding process as a final thermochemical treatment. Tested in dry sliding contact against an alumina ball as a static partner, the tribological responses of the specimen were analyzed and compared with an uncoated specimen. Friction coefficients, calculated from volume loss, were around .58 for all specimens except the uncoated specimen at 10 N of applied load. Wear scar analyses revealed the occurrence of several wear mechanisms that is polishing, oxidation, wear debris formation, surface binder removal, grain fragmenting, and grain pull‐out.
Materials for improved lifetime of saggar in production of Li‐ion cathode powders
Authors: Waetzig Katja , Hutzler Thomas , Zschippang Eveline 
Published: August 2024

AbstractCeramic saggars of mullite‐cordierite are currently used to produce cathode powders for lithium‐ion batteries. Strong interactions occur between the LiNi0.8Mn0.1Co0.1O2 (NMC) precursor in the temperature range of calcination (750–1000°C) leading to corrosion and formation of cracks in the saggar. The frequent failure of saggar causes a lot of waste, which could be reduced by choosing corrosion‐resistant materials. To understand the corrosion mechanism in the system MgO–Al2O3–SiO2, the materials MgO, Al2O3, MgAl2O4, and SiC (instead of SiO2) were embedded in premixed NMC precursor and calcined at T = 780°C for 50, 100, 150 and 200 h. The formed phases were determined by phase and microstructure analysis. Finally, the formation of LiAlO2 and Li5AlO4 is associated with a lower growth rate of the corrosion layer compared with Li4SiO4, while MgO is inert. The reactivity with NMC can be ordered as follows: SiO2 > Al2O3 > MgO.

Published: August 2024

SummaryThree different Acacia seeds (A. retinodes, A. provincialis and A. tenuissima) harvested from different locations and in different years were analysed for their variations in proximate and mineral composition. Results showed no one species had the highest content across all proximate and mineral analyses, for example, A. retinodes Harmans 2020 had the highest ash (3.7%), A. retinodes Harmans 2022 had the highest protein content (31.3%), A. tenuissima Hindmarsh 2020 had the highest fat content (18.5%) and A. provincialis Tarrington 2022 had the highest magnesium content (469 mg/100 g). Principle component analysis was carried out to determine the effect of species, harvest locations and years on the chemical composition. A biplot of the first two principal components with a total of 60.5% variation showed clustering based on harvest years. The compositions of the Acacia seeds were determined to be affected by species, harvest location and year differences. However, a complete gene–environment interaction study is needed to validate this.

ObjectivesThe National Clinical Database (NCD) Urology Division commenced registration in April 2018 in Japan. This is the first report to focus on five surgeries for which detailed information is registered.MethodsWe herein describe annual trends in and the complication grades of the following five surgeries: partial nephrectomy, radical nephrectomy, radical cystectomy, radical prostatectomy, and pyeloplasty, using the NCD. A total of 149 417 patients treated with the five types of surgeries based on NCD data were enrolled in this report.ResultsThe number of patients was 55 630 for partial/radical nephrectomy from April 2018 to December 2021, 83 653 for radical prostatectomy from April 2018 to December 2021, and 9342 for radical cystectomy from January 2020 to December 2021. In 2021, partial nephrectomy was performed on 7416 cases, radical nephrectomy on 7739 cases, radical prostatectomy on 22 692 cases, radical cystectomy on 4677 cases, and pyeloplasty on 792 cases.ConclusionsThe results obtained showed that a robot‐assisted or laparoscopic procedure has replaced open surgery as the common approach for all five surgeries. An analysis of NCD data may be useful for understanding trends in surgical procedures across the major field of urology.
Molecular dynamics simulations on ferroelectricity of AlN thin films
Authors: Deng Binghui , Shi Jian , Shi Yunfeng 
Published: August 2024

AbstractThe recent realization of ferroelectricity in scandium‐ and boron‐substituted AlN thin films has spurred tremendous research interests. Here we established a molecular dynamics simulation framework to model the ferroelectricity of AlN thin films. Through reparameterization of Vashishta potential for AlN, the coercive field strength and the AlN polarization were found to be close to experimental values. Furthermore, we examined the effects of film thickness, temperature, in‐plane strain on polarization‐electric field hysteresis loop, and the thickness‐dependent Curie temperature. Lastly, we incorporated electrodes towards atomic‐level modeling of ferroelectric device, by considering the induced charge at the interface between electrodes and ferroelectric film. We found that low dielectric contrast significantly lowers the coercive field for switching AlN.

AbstractTailoring of the stoichiometry, crystallinity, and microstructure of manganese oxides (MnOx) is of utmost importance for technological applications in the field of catalysis, energy storage, and water splitting. In this work, α‐Mn2O3, α‐Mn3O4, and MnO thin films with defined stoichiometric compositions and crystal structures were prepared by calcination of an anodically electrodeposited Mn‐oxyhydroxide precursor film in different gas atmospheres (air, inert, or reducing gas). The crystal structure and composition of the precursor and product films were determined by combining X‐ray diffraction, transmission electron microscopy, Raman spectroscopy, Rutherford backscattering spectrometry, and elastic recoil detection analysis. The anodically electrodeposited precursor film consists of nanocrystals of α‐Mn3O4 dispersed in an amorphous MnOOH matrix phase, and can be fully transformed into either crystalline α‐Mn2O3, α‐Mn3O4, or MnO upon calcination in an oxidizing, inert or reducing atmosphere, respectively. In situ high‐temperature X‐ray diffraction was applied to derive the phase transformation kinetics, resulting in a corresponding activation energy which decreases in the order α‐Mn2O3 (268 kJ/mole) > MnO (102 kJ/mole) > α‐Mn3O4 (60 kJ/mole). The disclosed synthesis routes for the preparation of single‐phase MnOx films with a defined crystal structure and stoichiometry can be exploited for a wealth of applications.

Published: August 2024

AbstractIntroductionIn this study, the effects of adding titanium dioxide nanotubes (TiO2) to 3D‐printed denture base resin on the mechanical and physical properties of denture bases were examined for the first time.MethodsThe specimens were digitally created using 3D builder software from Microsoft Corporation through computer‐aided design. In accordance with the test specifications for transverse strength, impact strength, hardness, surface roughness, and color stability, specimens were designed and printed with certain dimensions following relevant standards. TiO2 nanotubes (diameter: 15–30 nm and length: 2–3 μm) were added to the 3D‐printed denture base resin (DentaBase, Asiga, Australia) at 1.0% and 1.5% by weight. Flexural strength, impact strength (Charpy impact), hardness, surface roughness, and color stability were evaluated, and the collected data were analyzed with ANOVA followed by Tukey's post hoc test (α = 0.05). Field emission scanning electron microscopy (FESEM) and energy dispersive x‐ray spectroscopy (EDX) mapping were used to evaluate the dispersion of the nanotubes.ResultsCompared with those of the control group (0.0 wt.% TiO2 nanotubes), the average flexural, impact, and hardness values of the 1.0 and 1.5 wt.% TiO2 nanotube reinforcement groups increased significantly. Both nanocomposite groups showed significant color changes compared to that of the pure resin, and there was a considerable reduction in the surface roughness of the nanocomposites compared to that of the control group.ConclusionAdding TiO2 nanotubes to 3D‐printed denture base materials at 1.0 and 1.5 wt.% could enhance the mechanical and physical properties of the material, leading to better clinical performance.Clinical SignificanceIn terms of clinical applications, 3D‐printed denture base material has been shown to be a viable substitute for traditional heat‐cured materials. By combining this with nanotechnology, existing dentures could be significantly enhanced, promoting extended service life and patient satisfaction while addressing the shortcomings of the current standard materials.

AbstractChannel catfish (Ictalurus punctatus) and Nile tilapia (Oreochromis niloticus) are two aquaculture species of great importance. Intensive production is often hindered by poor growth performance and disease mortality. The aim of this study was to evaluate the potential of a commercial fermented yeast product, DVAQUA, on channel catfish and Nile tilapia growth performance metrics and disease resistance. Channel catfish and Nile tilapia were fed practical diets supplemented with 0%, 0.1% or 0.4% of DVAQUA over approximately 2‐month feeding periods in recirculation aquaculture systems. To assess the potential of the postbiotic against common aquaculture pathogens, juvenile catfish were subsequently challenged by immersion with Edwardsiella ictaluri S97‐773 or virulent Aeromonas hydrophila ML09‐119. Nile tilapia juveniles were challenged by injection with Streptococcus iniae ARS‐98‐60. Serum lysozyme activity, blood chemistry and growth metrics were measured at the end of the feeding period, but no differences were observed across the different metrics, except for survival. For the pathogen challenges, there were no differences in endpoint mortality for channel catfish with either pathogen (p > .05). In contrast, Nile tilapia survivability to S. iniae infection increased proportionally to the inclusion of DVAQUA (p = .005). Changes to sera lysozyme activity were also noted in the tilapia trial, with a reduction of activity in the fish fed the 0.4% DVAQUA diet compared to the control diet (p = .031). Expression profiles of proinflammatory genes and antibodies were also found to be modulated in channel catfish fed the postbiotic, indicating some degree of protective response. These results suggest that this postbiotic may be beneficial in protecting Nile tilapia against S. iniae infection by influencing immune parameters and additional research is needed to evaluate the potential of this DVAQUA for improving catfish health and disease control.
