The Dark Triad of brand personality: Scale development and validation
Authors: Malär Lucia , Giuffredi‐Kähr Andrea 
Published: July 2024

AbstractDespite the considerable magnitude of negative brand personalities in the marketplace, prior research has disproportionately focused on positive personality traits. To address this research gap, the authors present a conceptual and empirical approach that draws from the Dark Triad of psychology and applies it to the branding domain. They conceptualize and validate the Dark Triad of brand personality which comprises brand narcissism, Machiavellianism, and psychopathy dimensions. Through a multiphase scale development process, a reliable and valid 12‐item brief version of the Dark Triad of brand personality is created, enabling its assessment in both research and management contexts. Examining the Dark Triad in branding is crucial as it provides a unique lens to understand the rise of negative, dark brand personalities. It accounts for brand personality aspects not yet captured by existing scales, including manipulation, exploitation, grandiosity, and lack of empathy. This introduction of the Dark Triad brand personality opens new avenues for research into brand transgressions and ethics in brand management. In terms of managerial implications, insights from this research can inform strategic brand management, enabling companies to better manage their brand's image.
The influencer‐entrepreneurship journey: A model of staged progression
Authors: Cheng Zixuan Mia , de Regt Anouk , Young Kai‐Yi 
Published: July 2024

AbstractWith the ever‐increasing digitalization of society, a growing number of people are inspired to start up their own digital ventures. Within this context, a specific aspect of content entrepreneurship stands out—social media influencers. These influencers attract brands due to their attentional capital and persuasive power. Currently, the development of such influence is not instantaneous but a progressive journey, with influencers exhibiting varying degrees of influence at different stages. For brands aiming to foster effective collaborations, understanding these stages is crucial. However, existing literature lacks a comprehensive theoretical structure that encompasses the full spectrum of the influencer's journey. As such, drawing from the entrepreneurship literature, this paper proposes a model that delineates how social media users develop and enhance their brand as influencer‐entrepreneurs and how their roles transform across the various stages of entrepreneurial progression and facilitate strategic marketing engagement. The proposed model comprises five stages: influence potential, influence formulation, influence competence, influence monetization, and influence reward. In light of the collaborative dynamics between influencers and brands, the model further provides strategic guidance for brand managers and marketers on engaging with influencers at various stages of their journey.

Published: July 2024

AbstractMechanically robust and ionically conductive hydrogels poly(acrylamide‐co‐2‐acrylamido‐2‐methylpropanesulfonate‐lithium)/TiO2/SiO2 (P(AM‐co‐AMPSLi)/TiO2/SiO2) with inorganic hybrid crosslinking are fabricated through dual in situ sol‐gel reaction of vinyltriethoxysilane (VTES) and tetrabutyl titanate (TBOT), and in situ radical copolymerization of acrylamide (AM), 2‐acrylamide‐2‐methylpropanesulfonate‐lithium (AMPSLi), and vinyl‐SiO2. Due to the introduction of the sulfonic acid groups and Li+ by the reaction of AMPS with Li2CO3, the conductivity of the ionic hydrogel can reach 0.19 S m−1. Vinyl‐SiO2 and nano‐TiO2 are used in this hybrid hydrogel as both multifunctional hybrid crosslinkers and fillers. The hybrid hydrogels demonstrate high tensile strength (0.11–0.33 MPa) and elongation at break (98–1867%), ultrahigh compression strength (0.28–1.36 MPa), certain fatigue resistance, self‐healing, and self‐adhesive properties, which are due to covalent bonds between TiO2 and SiO2, as well as P(AM‐co‐AMPSLi) chains and SiO2, and noncovalent bonds between TiO2 and P(AM‐co‐AMPSLi) chains, as well as the organic frameworks. Furthermore, the specific capacitance, energy density, and power density of the supercapacitors based on ionic hybrid hydrogel electrolytes are 2.88 F g−1, 0.09 Wh kg−1, and 3.07 kW kg−1 at a current density of 0.05 A g−1, respectively. Consequently, the ionic hybrid hydrogels show great promise as flexible energy storage devices.
On the efficient preconditioning of the Stokes equations in tight geometries

Published: July 2024

AbstractIt is known (see, e.g., [SIAM J. Matrix Anal. Appl. 2014;35(1):143‐173]) that the performance of iterative methods for solving the Stokes problem essentially depends on the quality of the preconditioner for the Schur complement matrix, . In this paper, we consider two preconditioners for : the identity one and the SIMPLE one, and numerically study their performance for solving the Stokes problem in tight geometries. The latter are characterized by a high surface‐to‐volume ratio. We show that for such geometries, can become severely ill‐conditioned, having a very large condition number and a significant portion of non‐unit eigenvalues. As a consequence, the identity matrix, which is broadly used as a preconditioner for solving the Stokes problem in simple geometries, becomes very inefficient. We show that there is a correlation between the surface‐to‐volume ratio and the condition number of : the latter increases with the increase of the former. We show that the condition number of the diffusive SIMPLE‐preconditioned Schur complement matrix remains bounded when the surface‐to‐volume ratio increases, which explains the robust performance of this preconditioner for tight geometries. Further on, we use a direct method to calculate the full spectrum of and show that there is a correlation between the number of its non‐unit eigenvalues and the number of grid points at which no‐slip boundary conditions are prescribed. To illustrate the above findings, we examine the Pressure Schur Complement formulation for staggered finite‐difference discretization of the Stokes equations and solve it with the preconditioned conjugate gradient method. The practical problem which is of interest to us is computing the permeability of tight rocks.

Published: July 2024

AbstractObjectiveTo investigate the utility of preprocedural paracetamol on reducing pain scores post office‐based laryngeal procedures.Study DesignProspective, controlled before‐after comparative study.SettingControlled prospective before‐after study.MethodsA retrospective analysis was performed of 100 patients who underwent office‐based laryngeal procedures without preprocedural analgesia at our center to establish a control group. Age, sex, procedure type, and amount of substance used were documented as well as postprocedural pain score. Pain scores were recorded every 5 minutes for 30 minutes following office‐based laryngeal procedures. A prospective arm of this study was then performed in which every patient undergoing office‐based laryngeal procedures at our center between September 2019 and December 2020 was administered 1000 mg of paracetamol prior to their procedure. The postprocedure pain scores of the 2 groups were then compared.ResultsA hundred patients were included in the retrospective arm and 75 patients were included in the prospective arm, receiving 1000 mg of paracetamol a median of 45 (interquartile range: 30‐53) minutes prior to their procedure. The 2 groups were matched for age, sex, and type of laryngeal procedure. Both nonanalgesia and analgesia groups demonstrated a similar proportion of patients who experienced any pain (47% and 48%, respectively) postprocedurally. The prospective arm of this study however reported a statistically significant reduction in the magnitude of their pain scores at all points postprocedurally (P = .005).ConclusionParacetamol preprocedurally reduces the severity of pain in office‐based laryngeal procedures and would be a useful consideration for patients who are likely to experience significant postprocedural pain.Level of EvidenceLevel 3.
Can irrelevant self‐related information in working memory be actively suppressed?

Published: July 2024

AbstractTo utilize the resource of working memory efficiently, the brain actively suppresses irrelevant information to focus cognitive resources on the task at hand. However, whether task‐irrelevant self‐related information can be suppressed is still an open question. This study explores the inhibitory effects of various types of identity‐associated information (self, friend, stranger) with an irrelevant distracting paradigm, in which participants are required to memorize the color while ignoring the shape during a memory array. In the subsequent test array, participants are asked to judge whether the color of the test item is the same as the memorized one, while the ignored shape features could also change. The results are as follows. (1) Self‐associated information survived the inhibitory effect no matter whether the interstimulus interval (ISI) was short or long. (2) Stranger‐associated information remained inhibitory effect in a long ISI (3000 ms). The results indicate that self‐associated information can bypass the executive system and remain active in working memory processing.
Significantly enhanced dielectric properties of Ti3C2Tx MXene/MoS2/methylvinyl silicone rubber ternary composites by tuning the particle size of MoS2
Authors: Zeng Yu , Tang Lu 
Published: July 2024

AbstractTo realize the great potential of silicone rubber in advanced electronics, high dielectric constant and low loss tangent are currently pursued. Adding a third phase to conductive filler/silicone rubber composites may enhance the properties of the composites, but the appropriate particle size of the third phase is an open question. Here, MoS2 was used as the third phase to prepare the Ti3C2Tx MXene/MoS2/methylvinyl silicone rubber (VMQ) ternary composites, and the influence of different sizes of MoS2 (200 nm and 2 μm) on the dielectric performance of the composites was investigated. The dielectric constant of the Ti3C2Tx MXene/VMQ composites with 5 wt% MoS2 nanoparticles shows a 279% enhancement from 2.78 to 7.75 at 103 Hz, better than that of the Ti3C2Tx MXene‐MoS2 hybrid fillers/VMQ composites. Compared with micron MoS2, nano MoS2 can significantly enhance the dielectric performance of conductive filler/polymer composites because of shorter interparticle distances and enhanced interfacial polarization. Meanwhile, the composites exhibit low loss tangent (lower than 0.0015) and good thermal stability (up to 400°C) because of the low filling amounts of Ti3C2Tx MXene and MoS2 nanoparticles. Excellent flexibility with Young's modulus of 285 kPa and elongations break of 446% was also obtained. The design of these ternary composites greatly improves the dielectric and mechanical properties, which means that the dielectric material has a broad application prospect in modern electronics industry.Highlights
High dielectric constant was gained in Ti3C2Tx MXene/5n‐MoS2/VMQ composites.
The MXene/5n‐MoS2/VMQ composites exhibited excellent mechanical properties.
Appropriate filler size can benefit the performance of polymer composites.
Design and fabrication of highly aligned poly(l‐lactide‐co‐ε‐caprolactone) nanofiber yarns and braided textiles

Published: July 2024

AbstractAn approach that combines a modified electrospinning method with thermal stretching post‐treatment is designed to fabricate poly(l‐lactide‐co‐ε‐caprolactone) (PLCL) electrospun nanofiber yarns (ENYs). The nanofiber diameter in the PLCL ENYs is found to present an increasing trend with the increasing of polymeric concentration. When the PLCL concentration reaches 13% (w/v), the as‐generated ENYs show bead‐free and uniform nanofibrous structure. Then, a thermally stretching technique is applied to process the primarily‐obtained PLCL ENYs. When the stretching temperature is set as 60 °C, the thermally‐stretched PLCL ENYs present superior fiber orientation and notably enhanced crystallinity, thus resulting in dramatically increased mechanical properties. Finally, the thermally stretched PLCL ENYs are further processed into braided fabrics, and their mechanical properties are found to possess an obviously increased trend with the increasing of ENY numbers, demonstrating the adjustment feasibility of the mechanical properties of ENY‐based textiles by controlling the ENY numbers. Importantly, the in vitro cell studies demonstrate that the ENY‐based braided textiles significantly support the adhesion and proliferation of human dermal fibroblasts (HDFs). In all, the present study provides an easily‐handling strategy to fabricate high performance PLCL ENYs, which shows promising future for the generation of advanced biomedical textiles.
Harmony under threat: does resource‐mediated stress affect the (caste‐based) social network of leaf‐cutting ant colonies?

AbstractBACKGROUNDManaging pest species of eusocial insects, such as leaf‐cutting ants, poses significant challenges. Controlling them requires understanding of how toxic plant substrates and ant baits are recognized by foragers, transported to the nest, shared among workers and managed by gardeners cultivating the symbiont fungus garden. Despite this, little is known about how unsuitable resources might impact social interactions within ant colonies. This study aims to investigate whether the provision of a suitable substrate (copperleaf) and a toxic substrate (nasturtium leaves) affects the social network dynamics within colonies of two leaf‐cutting ant species: Acromyrmex molestans and Acromyrmex subterraneus. The interactions between castes were recorded and subjected to social network analyses.RESULTSInitial foraging duration increased for A. subterraneus provided with copperleaf, although no difference was observed for the other species and resource combinations. The social network structure was similar for both species when copperleaf leaves were provided as a substrate. However, notable alterations occurred with nasturtium leaf provision, leading to higher integration of gardeners in interactions and noticeable changes in the generalist worker network centrality, particularly in A. subterraneus.DISCUSSIONThe observed changes in social interactions, particularly in A. subterraneus, suggest that increasing gardener interactions with other castes expedites the movement of the substrate within the colony. This maximizes the potential toxic effect on the colony. © 2024 Society of Chemical Industry.

AbstractLicorice (Glycyrrhiza spp.) has been a cornerstone of traditional Chinese and Japanese medicine. This systematic review and meta‐analysis aimed to evaluate the efficacy of licorice formulations, alone or in combination with other herbs, on liver function enzymes in patients with primary liver disease. We systematically searched MEDLINE, Embase, Scopus, Web of Science, and Cochrane Library up to April 2024. Randomized controlled trials (RCTs) comparing the effects of Glycyrrhiza spp. preparations versus placebo or standard of care controls were included. Standard Cochrane methods were used to extract data and appraise eligible studies. A total of 15 RCTs, involving 1367 participants, were included in the analysis. The studies varied widely in geographical location, duration, and licorice preparations used. Licorice significantly reduced alanine aminotransferase (ALT) by 15.63 U/L (95% CI: −25.08, −6.18; p = 0.001) and aspartate aminotransferase (AST) by 7.37 U/L (95% CI: −13.13, −1.61; p = 0.01) compared to control groups. Subgroup analyses revealed that purified glycyrrhizic acid compounds were particularly effective, showing greater reductions in ALT and AST without significant heterogeneity. Although licorice treatment did not significantly impact gamma‐glutamyl transferase and total bilirubin (TBIL) levels overall, specific licorice‐herb preparations did show a notable reduction in TBIL. The safety profile of licorice was consistent with known side effects, predominantly mild and related to its mineralocorticoid effects. Despite heterogeneity and potential language bias, the findings suggest that licorice can enhance liver function. Further studies should standardize licorice preparations and explore its role in multifaceted herbal formulations to better understand its hepatoprotective mechanisms.

AbstractDeveloping high‐efficiency durable electrocatalysts in wide pH range for water splitting is significant for environmentally‐friendly synthesis of renewable hydrogen energy. Herein, a facile method by dealloying designable multicomponent metallic glass precursors is reported to synthesize amorphous‐crystalline heterostructured nanoporous high‐entropy alloys (AC‐HEAs) of CuAgAuPtPd, CuAgAuIrRu, and CuAgAuPtPdIrRu, heaped up by nanocrystalline particles with an average size of 2‐3 nm and the amorphous glued phase. The synthesized AC‐HEA‐CuAgAuPtPd owns highly catalytic performances for hydrogen evolution reaction (HER), with 9.5 and 20 mV to reach 10 mA·cm−2 in 0.5 m H2SO4 and 1.0 m KOH, and AC‐HEA‐CuAgAuIrRu delivers 208 and 200 mV for oxygen evolution reaction (OER). Moreover, a two‐electrode electrolyzer made of the AC‐HEA‐CuAgAuIrRu bifunctional electrodes exhibit a low cell voltage of 1.48 and 1.49 V in the acidic and alkaline conditions at 10 mA·cm−2 for overall water splitting. Combining the enhanced catalytic activities from nanoscale amorphous structure and atom‐level synergistic catalyst in AC‐HEAs provides an effective pathway for pH‐universal electrocatalysts of water splitting.

Published: July 2024

ABSTRACTEzetimibe (EZE) is a dyslipidemic agent used to treat hyperlipidemia along with statins and diet changes. To ascertain the drug's degradation profile, stress tests were conducted on it in accordance with International Council for Harmonization recommendations. An ultrahigh‐performance liquid chromatography–mass spectrometry method was developed and validated for the identification and quantification of EZE and its degradants. Using preparative high‐performance liquid chromatography, all impurities were isolated, and their structures were characterized thoroughly using advanced spectral techniques. The drug was relatively stable in basic, peroxide, photolytic, and thermal conditions; however, five degradants were observed in acid degradation. Among the five degradants, three degradation products eluted as Peak‐1, Peak‐2, and Peak‐3 which were found to be novel impurities that were not reported previously. However, the remaining two impurities were identified as Peak‐4 and Peak‐5, despite the insufficient information available. The present study has focused on the isolation of these five acid degradation products and the structural confirmation of these degradants by highly efficient spectral techniques. Moreover, the possible degradation mechanism of the azetidinone ring in the presence of acid has been explained, which might be helpful in determining the quality and purity of EZE and similar pharmaceutical compounds.
