AbstractThe study of teacher well‐being is critically important. However, teacher well‐being studies are lacking in Africa, Asia, and the Middle East, and also generally in low‐income countries. This exploratory case study sought to identify teachers' perceptions of work‐related characteristics and personal practices associated with well‐being and burnout in three underrepresented, diverse sites: Battambang, Cambodia; Bungoma, Kenya; and Doha, Qatar. Ninety teachers participated in in‐depth interviews (Qatar N = 21, Cambodia N = 33, Kenya N = 36), as well as 16 principals and 11 policymakers. Qualitative analysis was conducted using data‐driven, emergent codes. Findings revealed that teachers attributed remarkably similar processes and key components to their well‐being (e.g., engagement school‐wide or district‐wide, schools attending to teachers' personal needs) and burnout (e.g., administrative burden, student misbehavior) across all three sites, with a few notable differences worthy of future follow‐up. Few teachers could name any well‐being programs at their school.

Authors: Wang Wei , Zhang Jie 
Published: August 2023

AbstractThis study aimed to apply psychological strain theory to explore the relationship between psychological strain and suicidality among Chinese young adults with a moderating effect of perceived social support. A questionnaire was administered with the Multidimensional Scale of Perceived Social Support, Suicidal Behaviors Questionnaire‐Revised, and Psychological Strain Scale among 13,250 college students across China. The main determinants of suicidal behavior were examined with multiple linear regression. Two steps of multiple regression were employed to define the moderating effect of social support. A positive relationship between psychological strain and suicidality was reported in the study, and social support was confirmed as a moderating factor between psychological strain and suicidal behavior.

Published: August 2023

AbstractProton exchange membranes (PEMs) play a crucial role in energy storage and conversion technologies such as fuel cells, redox flow batteries, and water electrolysis. Currently, perfluorosulfonic acid polymer (PFSA) membranes are the most commonly used PEM materials. However, PFSA membranes possess certain drawbacks, including the high dependence of proton conductivity on humidity, low glass transition temperatures, and complex synthesis processes. In recent decades, significant efforts have been dedicated to developing various alternative PEM materials, such as the sulfonated products of polyether ether ketone, poly(phenylene oxide), polysulfone, and polyimide. However, the backbones of these polymers often contain heteroatoms that are prone to breaking under practical working conditions, leading to reduced chemical stability. In contrast, all‐carbon backbone aromatic polymers exhibit excellent chemical stability, thermal stability, and mechanical properties, as well as high proton conductivity upon incorporating suitable acidic groups, which makes them promising alternatives for PEM materials. This review aims to summarize the recent research progress about all‐carbon backbone aromatic polymers, with a specific focus on synthesis strategies, structure–performance relationships, and applications in PEMs.

AbstractObjectiveHigh rates of non‐adherence to oral medications in breast cancer (BC) patients have been reported. Here we provide an up‐to‐date systematic review of the interventions aimed at increasing adherence to oral medication in BC patients, with a particular focus on the content of the interventions.MethodsPubMed, Scopus, Embase and Ovid databases and reference lists of relevant studies were searched through October 2022. Studies which (1) described an intervention aimed at increasing adherence to oral anticancer medication, (2) included (or planned to include) at least one sub‐group of BC patients, (3) were written in English, and (4) with full‐text available were included. The contents of the interventions were coded using the Behavior Change Technique Taxonomy. Quality assessment was conducted using Downs and Black scale.ResultsThirty‐six studies met the inclusion criteria and involved a total sample of 28,528 BC patients. Interventions were mainly delivered with eHealth devices (n = 21) and most of them used mobile app. Other studies used in‐person modalities (e.g., CBT, relaxation technique) or written materials (e.g., psycho‐educational booklet). The behavior change techniques most frequently implemented were “problem solving,” “social support,” “information about health consequences,” and “prompts/cues”. Quality assessment revealed that the higher risk of bias refers to the selection process.ConclusionsThe use of reminders, monitoring patients' medication‐taking behaviors and giving feedback were the most frequently implemented techniques in those interventions that resulted significant. If these preliminary observations were to be confirmed by future comparative studies, they should be taken into account when developing new interventions.
Differential dynamic programming for finite‐horizon zero‐sum differential games of nonlinear systems
Authors: Zhang Bin , Jia Yingmin , Zhang Yuqi 
Published: August 2023

AbstractIn this article, we present an iterative algorithm based on differential dynamic programming (DDP) for finite‐horizon two‐person zero‐sum differential games. The technique of DDP is used to expand the Hamilton–Jacobi–Isaacs (HJI) partial differential equation into higher‐order differential equations. Using value function and saddle point approximations, the DDP expansion is transformed into algebraic matrix equation in integral form. Based on the algebraic matrix equation, a DDP iterative algorithm is developed to learn the solution to the differential games. Strict proof is proposed to guarantee the iterative convergences of the value function and saddle point. The new algorithm is fundamentally different from existing results, in the sense that it overcome the technical obstacle to address the time‐varying behavior of HJI partial differential equation. Simulation examples are given to demonstrate the effectiveness of the proposed method.

Published: August 2023

AbstractResponsive biohybrid systems have the potential to overcome limitations of both natural and artificial machines in terms of efficiency, accuracy, and functionality. As functional units, living cells act as bricks for building biohybrid machines, where the extracellular matrix mimics hydrogels to act as ideal biological concrete. Combining living cells with hydrogels offers unique advantages in simulating human tissues or organs, which unleashes the future of biohybrid systems, and thus has attracted extensive attention. Herein, recent progress in cell‐laden hydrogel‐based responsive biohybrid systems is summarized to provide a basic understanding of how these systems are built from the bottom up and how to achieve the complex functions. This review focuses on advanced manufacturing technologies for responsive biohybrid systems, including laden cells in hydrogel matrices, three‐dimensional bioprinting, and microfluidic manufacturing. Subsequently, the innovative applications of these works, including actuators, sensors, and engineered functional materials, are presented, along with different triggering mechanisms that are highlighted. Finally, the current challenges and future opportunities in the field are addressed. This review provides a unique perspective and is hoped to inspire fields such as biohybrid technologies, soft robots, and tissue engineering.

Published: August 2023

AbstractAn asymmetric wound dressing acts as a skin‐like structure serves as a protective barrier between a wound and its surroundings. It allows for the absorption of tissue fluids and the release of active substances at the wound site, thus speeding up the healing process. However, the production of such wound dressings requires the acquisition of specialized tools, expensive polymers, and solvents that contain harmful byproducts. In this study, an asymmetric bacterial cellulose (ABC) wound dressing using starch as a porogen has been developed. By incorporating silver‐metal organic frameworks (Ag‐MOF) and curcumin into the ABC membrane, the wound dressing gains antioxidant, reactive oxygen species (ROS) scavenging, and anti‐bacterial activities. Compared to BC‐based wound dressings, this dressing promotes efficient dissolution and controlled release of curcumin and silver ions. In a full‐thickness skin defect model, wound dressing not only inhibits the growth of bacteria on infected wounds but also regulates the release of curcumin to reduce inflammation and promote the production of epithelium, blood vessels, and collagen. Consequently, this dressing provides superior wound treatment compared to BC‐based dressing.

Published: August 2023

AbstractThe spinel Mn‐based cathodes with 3D Li+ diffusion channels, high voltage, and low‐cost show promise for developing high‐power lithium‐ion batteries (LIBs). But the disproportionation and Jahn–Teller distortion lead to structural degeneration and capacity decay, especially at high working temperatures. Herein, considering the merits of single crystals and orientation of exposed crystal planes, single‐crystal truncated octahedral LiMn2O4 (TO‐LMO) with exposed {111}, {100} and {110} facets is rationally designed, in which the mainly exposed {111} facets are truncated by a small portion of {100} and {110} facets. The Li‐deficient intermediate phase is innovatively proposed to prepare the single‐crystal TO‐LMO. The synergistic effects of single crystals and the orientation of exposed crystal planes significantly reduce the disproportionation of Mn3+ ions and thereby improve their structural stability. Consequently, the cycling stability of the single‐crystal TO‐LMO is remarkably enhanced, obtaining outstanding capacity retention of 84.3% after 2000 cycles, much better than that of 61.2% for octahedral LiMn2O4. The feasibility of preparing single‐crystal truncated octahedral LiNi0.5Mn1.5O4 with exposed {111}, {100}, and {110} facets via the Li‐deficient intermediate phase is further demonstrated. These findings offer new insight into regulating the orientation of exposed crystal planes and improving the reversibility of Mn‐based redox couples in LIBs.

Published: August 2023

AbstractHigh‐nickel layered oxide cathodes and lithium‐metal anode are promising candidates for next‐generation battery systems due to their high energy density. Nevertheless, the instability of the electrode–electrolyte interphase is hindering their practical application. Localized high‐concentration electrolytes (LHCEs) present a promising solution for achieving uniform lithium deposition and a stable cathode–electrolyte interphase. However, the limited choice of diluents and their high cost are restricting their implementation. Four novel cost‐effective diluents and their performance with highly reactive LiNiO2 cathode and Li‐metal anode are reported here. The results show that all the LHCE cells exhibit a Coulombic efficiency of >99.38% in Li | Cu cells and a capacity retention of >85% in Li | LiNiO2 cells after 250 cycles. Advanced characterizations unveil that the stable cell operation is due to well‐tuned electrode–electrolyte interphases and Li deposition morphology. In addition, online electrochemical mass spectroscopy and differential scanning calorimetry reveal that the gas generation and heat‐release are greatly reduced with the LHCEs presented. Overall, the study provides new insights into the role of diluents in LHCEs and offers valuable guidance for further optimization of LHCEs for high energy density lithium‐metal batteries.

AbstractSodium layered oxides feature in high capacity and diverse composition, however, are plagued by various issues including limited kinetics and interfacial instability with residual alkali. Conventional substitution/doping and heterogeneous coating are promising to tackle the problems of bulk and surface, respectively, but normally insufficient to address both. Herein, a post‐substitution strategy is proposed to modify primary sodium‐layered‐oxide particles that can simultaneously deal with bulk and surficial issues. As a typical example, post Ti‐substitution for O3‐NaNi1/3Fe1/3Mn1/3O2 is successfully performed by adjusting thermodynamic driving force, resulting in depth‐controllable Ti infusion from surface to bulk, as proved by energy dispersive spectroscopy maps collected at the cross‐section. Residual alkali species are efficiently diminished and benefited from the surface‐to‐bulk osmotic reaction, significantly improving Coulombic efficiency. Moreover, remarkable enhancements in reversible capacity (135 mAh g−1 at C/10), rate capability (74% retention at 5 C), and long‐term cycling stability (80% retention after 300 cycles at 2 C) are achieved by manipulating gradient‐like Ti distribution in a primary particle that brings with increased kinetics and strengthened interfacial stability, surpassing those given by rough heterotic coating and homogeneous Ti‐substitution. Such post‐substitution is expected to provide a universal strategy to modify primary layered‐oxide particles for developing advanced cathode materials of SIBs.
Stakeholder theory: Exploring systems‐theoretic and process‐philosophic connections
Authors: Valentinov Vladislav , Roth Steffen 
Published: August 2023

AbstractModern stakeholder theory is premised on the ‘integration thesis’, according to which business and ethics constitute an inseparable unity. For many management scholars, this thesis raised the difficult question of how far business can pursue ethical goals without losing its functional autonomy. We address this question by interpreting the integration thesis as the Luhmannian ‘unity of difference’ of business and ethics. This interpretation allows business and ethics to remain conceptually distinct, yet takes their very distinction to constitute a logical and dialectical unity as envisioned by the integration thesis. To justify this interpretation, we draw on the Luhmannian systems theory which accentuates the precariousness of the environment faced by business corporations, and on process philosophy which underscores the unique human capacity to navigate this precariousness by following social norms of ethical behaviour. We argue that a key prerequisite of successful stakeholder management is the activation of this human capacity.
Development of theoretical model for predicting flexural behavior of GFRP reinforced concrete beams with CFRP grid‐reinforced ECC

Published: August 2023

AbstractGlass fiber reinforced polymer (GFRP) concrete beams reinforced by carbon fiber reinforced polymer (CFRP) grid reinforced engineering cementitious composite (ECC) have excellent flexural performance and corrosion resistance in marine environments. However, the lack of a reliable theoretical model for predicting the flexural behavior of the hybrid beams makes it challenging apply them in the practical engineering. To address this issue, a series of numerical models were established to investigate the effects of key parameters on the flexural behavior of the hybrid beams, including the peak load, the neutral axis height, and the sectional stress distribution. Subsequently, based on the influence of the failures of different materials on the flexural performance of the hybrid beam, the loads of four feature points were calculated in the theoretical model to predict the entire load–displacement curve. Finally, the application range of the theoretical model was given based on the neutral axis height. The results showed that the cover thickness of the ECC, the GFRP reinforcement ratio and the cross‐sectional area of the CFRP grid were the key factors affecting the flexural performance of the hybrid beams. The theoretical model established in this study can predict the load–displacement curve accurately and can provide a reference for the subsequent design of the hybrid beams.

Published: August 2023

AbstractMost of the Italian infrastructures have been built since the mid‐twentieth century. Prestressed concrete (PC) has been widely used, especially for bridges and viaducts. These structures have proved effective over time, but their performance could be affected by degradation phenomena (i.e., corrosion of the tendons and residual prestressing) or construction defects (i.e., grouting of the ducts), which need to be accurately modeled. This paper focuses on the flexural response of two reduced‐scale, posttensioned, PC bridge girders, prestressed with two different jacking forces and tested under four‐point bending configuration. Four multidimensional numerical models were developed to simulate the experimental behaviors of the selected specimens, using two alternative computational strategies, namely, the finite element method (FEM) and applied element method (AEM). Three FEM modeling were considered, ranging from one‐dimensional lumped‐plasticity models to two‐dimensional and three‐dimensional (3D) spread‐plasticity models. Besides, 3D AEM models were developed into another software package. The accuracy and the computational costs of the two numerical strategies are discussed in this paper. Also, the main features of each numerical modeling technique are addressed, including comparisons between numerical and experimental global response data as well as the statistical characterization of the model error. Based on these different features, the authors also suggest the most suitable numerical strategy for future studies on PC girders.

AbstractStress-induced cardiovascular diseases characterized by inflammation are among the leading causes of morbidity and mortality in postmenopausal women worldwide. Estradiol (E2) is known to be cardioprotective via the modulation of inflammatory mediators during stress. But the mechanism is unclear. TNFα, a key player in inflammation, is primarily converted to its active form by 'A Disintegrin and Metalloprotease 17' (ADAM17). We investigated if E2 can regulate ADAM17 during stress. Experiments were performed using female FVB wild-type (WT), C57BL/6 WT, and G protein-coupled estrogen receptor 1 knockout (GPER-1 KO) mice and H9c2 cells. The study revealed a significant increase in cardiac injury and inflammation during isoproterenol (ISO)-induced stress in ovariectomized (OVX) mice. Additionally, ADAM17’s membrane content (mADAM17) was remarkably increased in OVX and GPER-1 KO mice during stress. However, in vivo supplementation of E2 significantly reduced cardiac injury, mADAM17, and inflammation. Also, administering G1 (GPER-1 agonist) in mice under stress reduced mADAM17. Further experiments demonstrated that E2, via GPER-1/PI3K pathway, localized ADAM17 at the perinuclear region by normalizing β1AR-Gαs, mediating the switch from β2AR-Gαi to Gαs, and reducing phosphorylated kinases, including p38 MAPKs and ERKs. Thus, using G15 and LY294002 to inhibit GPER-1 and its down signaling molecule, PI3K, respectively, in the presence of E2 during stress resulted in the disappearance of E2’s modulatory effect on mADAM17. In vitro knockdown of ADAM17 during stress significantly reduced cardiac injury and inflammation, confirming its significant inflammatory role. These interesting findings provide novel evidence that E2 and G1 are potential therapeutic agents for ADAM17-induced inflammatory diseases associated with postmenopausal females.
